SURGICAL STERILE FIELD

A surgical sterile field system includes an expandible flexible enclosure that is transparent in at least part of its expanse and a pair of gloves that are hermetically formed and sealed on a wall of the enclosure to allow access to an inside of the enclosure near a surgical site. Further, the system includes an incision site of a size corresponding to the required surgical site, e.g., the eye, chest or pelvic area. The site has an adhesive at least surrounding its exterior periphery that is attachable to the skin of the patient adjacent the surgical sight and a cover over the incision site adhesive which can be removed prior to use. The enclosure may include a pop-up frame to support it.

FIELD OF THE INVENTION

The present invention relates to a surgical sterile field. More specifically, the present invention relates to a surgical sterile field that is compact, portable, disposable, cost-effective and recyclable.

BACKGROUND OF THE INVENTION

Surgical procedures performed in a hospital have the benefit of the sterile conditions in hospital operating rooms. These include sterile instruments, surgical drapes, filtered air, as well as gloved and masked surgeons, anesthesiologists, nurses, and operating personnel. The drawback to this hospital procedure is the cost, which is particularly driven by the cost to keep the operating room sterile to protect the patient from infection and the cost of the hospital facilities.

One more recent procedure seeking to reduce the cost of minor surgeries is to carry them out in ambulatory surgery centers. While this reduces the cost of the hospital facility, it still needs to have a sterile operating room and gloved and masked operating personnel, which have costs associated with them. In addition, hospitals may have ordinary rooms dedicated to out-patient surgical procedures that do not require the elaborate sterilizing procedures of operating rooms. These are typically procedures where minor incisions are performed, e.g., the insertion of a cardiac monitor in the chest of a patient, so the patient is less exposed to infections. Nevertheless, the surgeon and other personnel will usually still wear full sterile surgical attire for these procedures.

To further reduce the costs associated with surgeries in hospitals as well as to provide patients with more comfort, an increasing number of physicians have been practicing office-based surgeries, or OBS. OBS are surgical or invasive procedures performed in a location other than a hospital or ambulatory surgery center. In an OBS the procedures, which may include eye surgery (e.g., cataract surgery, retina procedures, refractive lens exchange and oculoplastic surgery), can be performed in a suite located within the physician's office using minimal to moderate anesthetics. However, one major issue in practicing in an OBS is the risk of contamination.

To prevent contamination, the operating room needs to be continuously cleaned and disinfected to create a sterile environment. The surgeon and assistants must scrub their hands meticulously with disinfectant, and wear a sterile gown, gloves, a disposable mask, cap, and disposable shoe coverings. Further, the patient must be extensively covered with sterile drapes. In the case of eye surgery, the eye must be draped with a special sterile cover for intraocular surgery (cataract or vitrectomy). Further, all surgical instruments must be sterile, e.g., by autoclaving them with high pressure steam. These are challenging, especially for those physicians who do not enjoy the same resources as large medical facilities.

Various efforts have been made to help surgeons practice OBS more easily. For example, US Patent Application Publication No. 2015/0238264 of Kerns et al. discloses a sterile ophthalmic surgical drape system that can provide a sterile operating field for ophthalmic medical procedures. The sterile ophthalmic surgical system comprises a drape, a collapsible frame apparatus, a hole of sufficient size for a microscope, a fan, a filter, air directors and slits. The drape system may be configured to be used in conjunction with a surgical tray with presterilized instruments. However, in this drape system, there is no disclosure of how the surgeon can get his hands into the operating site without breaching the sterile environment, except by reverse air flow. Also, the drape does not form a complete sterile enclosure.

Another example is US Patent Application Publication No. 2022/0192780 of Okajima et al., which discloses a portable surgical system including a sterile enclosure and a plurality of sterile sleeves made of a composite-material. However, while it is called “portable,” the surgical system still requires a “rigid frame” structure. Further, in this system, the medical instruments are transferred into the enclosure via material ports that “may be opened and closed by various means, such as zippers, magnetic strips, hook-and loop fasteners.” These ports may cause contamination by introducing non-sterile air full of many particles, bacteria, and viruses, into the container.

The present invention has been made in view of the above-described circumstances to provide a surgical sterile field that is compact and provides an effective sterilized surgical site in a cost-effective manner without relying on a rigid frame structure or requiring heavy equipment such as an electric pump, while providing a sterile way for the surgeon's hands to reach the surgical site.

SUMMARY OF THE INVENTION

The present invention is directed to a sterile surgical field system that has a flexible enclosure that is transparent in at least part of its expanse and at least one pair of glove chambers that are hermetically formed and sealed on a wall of the enclosure to allow access to an inside of the enclosure near a surgical site. The enclosure is presterilized, e.g., by heat or ultraviolet light. Further, the system includes an incision site of a size corresponding to the required surgical site. The site has an adhesive at least surrounding its exterior periphery that is attachable to the skin of the patient adjacent the surgical sight and a cover over the incision site adhesive which can be removed prior to use. As an alternative, the enclosure at the incision site can be cut by a surgical instrument to expose the surgical site rather than removing the cover.

The flexible enclosure may be inflatable by an external source of sterile air. However, alternatively, and preferably, the enclosure has a collapsible frame within it. A loop attached to an apex of the frame may be pulled away from a base of the frame, so the frame expands creating a vacuum in the enclosure that draws ambient air into the enclosure through a one-way valve with a HEPA filter. As a result, the enclosure is expanded into a bubble shape with a sterile interior.

When used for eye surgery, e.g., cataract removal, it has a transparent portion of the enclosure attached, e.g., by adhesive, to the objective lens of a microscope used by the surgeon during the operation. The system also includes an attachment portion in the form of an eye opening in the enclosure adjacent the patient's eyes, which acts as the surgical site, so it has an adhesive along its outer peripheral edge and an exterior removable cover. A further entrance opening is provided in the enclosure through which cables for powering a surgical instrument such as an ultrasonic phacoemulsification surgical instrument, as well as irrigation and aspiration tubes may pass.

The system is provided at a physician's office with the enclosure collapsed and already sterilized and in a sealed package. If the surgical instrument is of the disposable type, it may be presterilized and provided within the enclosure with its power and fluid tubes partially sealed within a tube in the wall of the enclosure. This will allow the attachment of the fluid lines and power cable to a surgical system outside the enclosure. The transparent portion of the enclosure is fastened to the objective lens of the microscope by the adhesive provided and the enclosure is inflated. During or after expansion or inflation of the enclosure, the eye opening is sealed to the skin of the patient around the eye or eyes. In such a state, the interior of the enclosure is sterile, and the rest of the operating room need not be. The surgeon can put his or her hands in the gloves, pick up the surgical instruments and perform the surgery without contaminating the surgical field. Materials for bandaging the surgical wound that have been presterilized and placed in the enclosure before the procedure can then be used to bandage the patient. In this embodiment everything needed for the procedure is located within the enclosure. At that point, the enclosure can be detached from the microscope and from the skin of the patient. It and its contents, where disposable instruments are used, can then be thrown away.

Having the instruments, medications and bandages sterilized and pre-positioned within the enclosure saves on the preoperative procedures. It is common for the implements, medications (e.g., aesthetics) and materials (e.g., bandages) needed for a procedure, even in an out-patient room, to be bar coded for identification. Before the procedure can begin, the instruments and materials must be gathered, have their bar codes read and placed in a convenient location for the procedure. This setup time is eliminated when everything is located in the enclosure supplied, thus reducing the time the room needs to be occupied. This means that more patients can be seen during the day.

This procedure for eye surgery can be expanded for use in surgical procedures on other parts of the body. In that setting or in eye surgery, additional instruments may be introduced into the sterile enclosure. An instrument tray with the other presterilized instruments may be provided with an adhesive layer over the top of the tray and a cover release layer over the adhesive. The cover layer is removed, and the tray is stuck to the enclosure by the adhesive. To reach the instruments, the surgeon cuts through the enclosure and the adhesive layer.

A particular use of the present invention is in minor surgical procedures such as the implantation of capsules (e.g., therapeutic time release capsules that contain medication (including chemotherapy drugs), hormones or antibiotics), or devices that stimulate or monitor the central or peripheral nervous system, diagnostic monitors, (including cardiac monitors) as well as the insertion of various types of catheters into the patient. See for example, the Adee, “The messy quest to replace drugs with electricity,” MIT Technology Review, May 30, 2024 and the Medtronic Insertable Cardiac Monitor (ICM) https://www.medtronic.com/us-en/healthcare-professionals/products/cardiac-rhythm/cardiac-monitors/reveal-linq-icm/mobile-manager.html. On such catheter is the DxTerity™ diagnostic catheter of Medtronic.

Not only is the sterile surgical field of the present invention useful for surgery in doctor's offices, hospitals and ambulatory surgery centers, but it can also be used for eye surgery or general surgery in disaster relief operations, or a battlefield, or traffic accident cases. In these situations, every minute used in transporting a trauma patient to a hospital can be a matter of life and death. By using the surgical sterile field system of the present invention, procedures like suturing major arteries or veins to stop hemorrhaging can be performed at the disaster location before transporting the patient to the hospital for complete medical care. In addition, since the surgical sterile field system does not require any rigid frame structure, it is easy to carry and is by no means cumbersome.

The microsurgical sterile field embodiment of the present invention provides doctors with significant benefits because of its reduction in cost and infection rates. For those who practice OBS, the microsurgical sterile field of the present invention offers an ideal clinical setting since it makes surgical procedures more efficient, while eliminating all of the time, materials and cumbersome process needed to disinfect the operating room and sterilize the surgical gowns and drapes. The ecological (energy) footprints are also significantly reduced as a result.

DETAILED DESCRIPTION OF THE INVENTION

FIG.1shows a microsurgical sterile field system100of a first embodiment of the present invention for performing an ophthalmological operation. The surgical sterile field system100comprises an inflatable enclosure2that is made of flexible and inflatable materials, e.g., plastic. It has at least one pair of integral sterile gloves3used by a surgeon. The sterile gloves3are hermetically sealed to the wall of the enclosure2with their rims sealed against the outside environment, but so as to allow for access to the inside of the enclosure2by the hands of the surgeon.

FIG.1further shows a surgeon9performing an ophthalmological operation while viewing the incision site7through a microscope13attached to the microscope connection10. The enclosure2is flexible enough to allow the objective lens of the microscope10to be aligned with the incision site7at the patient's eye. In a particular version, the enclosure may include a clear window11at connection10to improve the surgeon's view. SeeFIG.2.

The microsurgical sterile field system100is simple and requires that only a small area be sterile compared to a traditional ophthalmological procedure. For instance, no disposal drapes or gowns are required. Accordingly, the microsurgical sterile field system100of the present invention makes it possible to efficiently perform an ophthalmological operation in a cost-effective and environmentally friendly manner, while minimizing the risk of contamination. This includes performing the operation in a doctor's office as opposed to a hospital surgical room or even an OBS suite.

FIG.2is a plan view of the enclosure ofFIG.1. It shows the microscope connection10and a cable port20. The microscope connection10comprises the view window11that is made of clear glass or hard plastic and a rim12surrounding the view window11. The rim12is configured to attach to the microscope objective, e.g., by an adhesive. The cable port20is formed on the wall of the enclosure2so that the power cord21, irrigation21aand/or evacuation tubes21bof a surgical instrument22can extend outside of the enclosure2through a seal. The surgical instrument and the other instruments23needed for the procedure and located in a surgical tray5are pre-sterilized and placed inside the enclosure2before it is sealed. As can be seen inFIG.2, there is an incision site7that is a portion of the enclosure. It can have adhesive along its periphery7athat allows it to be fixed to the skin of the patient. A cover is placed over this adhesive during manufacture of the enclosure. At the time of the procedure the cover can be removed, and the enclosure fixed to the skin of the patient, e.g., about the eye as shown inFIG.2. Once in place, the surgeon can cut through the enclosure with a scalpel on the instrument tray5to expose the tissue of the patient where the ocular surgery is to take place.

There is a filter30, such as a HEPA filter, through which air may be drawn into or pushed into the enclosure by a fan or a sterile pump (not shown) to keep the enclosure inflated during the procedure. In one embodiment, the enclosure2can be rapidly inflated by using a compressed gas cartridge (not seen) to push air through the filter30. As an alternative there is an entrance port6which is shown enlarged inFIG.3Athat can be used as a way to introduce air into the enclosure from a sterile fan, pump, or gas cartridge.FIG.3Billustrates the details of one embodiment of the entry port6formed on the wall of the enclosure2. The entry port6comprises a tubal body60, a cap61, and at least two elastic membranes62. As shown inFIG.3B, the elastic membranes62are stacked in the tubal body60in the longitudinal direction with a certain interval between them in which disinfectant solution or gel is filled. After removing the cap61, the entry port6allows for the entry of a sterilized tube or power cord into the enclosure2while minimizing the risk of contamination.

When the enclosure is fully in place and inflated, and the incision site7is affixed to the skin of the patient as shown inFIG.1, the surgeon places his hands in the gloves3, grasps a scalpel23and uses it to remove the portion of the enclosure within the confines of the incision site7to expose the underlying tissue of the patient. In a phacoemulsification procedure, an incision is made in the eye by the surgeon to expose the cataract using one of the tools (scalpel)23inFIG.2. Then the surgeon uses the ultrasonic handpiece22to break up the cataract while irrigation fluid is bathing the site from irrigation line21aand the pieces of cataract and excess fluid are drawn away from the area of the cataract by the aspiration line21b. If needed or desired, the handpiece can use alternatively use laser energy instead of ultrasonic vibration at the tip of a workpiece22to soften, breakup and remove a cataract. For example, the laser light source can be a laser in the handpiece22′ or a fiber-optic cable238extending from a laser outside the enclosure to the handpiece22′ inside the enclosure as shown inFIG.12. In this arrangement the fiber-optic cable is located inside a tube132and directs laser light pulses to a titanium target232. The effect of the light pulses hitting the target is to generate shockwaves that emulsify the cataract tissue. A channel214is formed between the inner surface of the handpiece22′ and the outer surface of the tube132for carrying irrigation fluid to the operating site. Tissue can be aspirated from the site by a suction force applied to the interior216of tube132.

FIG.4Ais a plan view of the surgical sterile field system100of the first embodiment. As shown in the drawing, two types of the attachment portions4have been formed on the enclosure2; one4ais for attaching an instrument tray5(FIG.5A) and another one4bis for use as an incision site. Although the embodiment shown inFIG.4Ahas two attachment portions4a,4b, an extra attachment portion4may be added if necessary.

As shown inFIG.4B, the attachment portion4ahas a band-aid type design containing two layers: an adhesive layer42disposed on the outer surface of the enclosure2, and a cover layer41disposed on the outer surface of the adhesive layer42. The cover layer41is made of paper or plastic film and can be easily peeled off by hand to expose the adhesive layer42, to which the instrument tray5ofFIG.5Aor an incision site on the body of the patient is attached.

As shown inFIGS.5A &5B, the instrument tray5is composed of a tray box50in which sterile medical instruments are store and three layers including a transparent layer53, an adhesive layer52, and a cover layer51stacked on a top of the instrument tray in this order. Similar to the cover layer41of the attachment portion4of the enclosure2, the cover layer51of the instrument tray5is made of paper or plastic film and can be easily peeled off by hand to expose the adhesive layer52. The adhesive layer52is disposed on the top of the transparent layer53, which covers the top portion of the tray box50. In one embodiment, the adhesive layer52is also formed transparent.

FIGS.6A-6Dillustrate the process of accessing medical instruments in the instrument tray5during a surgery. As shown inFIG.6A, first, the cover layer41of the attachment portion4of the enclosure2and the cover layer51of the instrument tray5are peeled off. Then, an upper surface of the instrument tray5is attached to the adhesive layer4of the attachment portion4of the enclosure2. In this embodiment shown inFIG.6A, the cover layer41and the adhesive later 42 of the attachment portion4extends along the edges of the attachment portion4. Likewise, the cover layer51and the adhesive layer52of the instrument tray5at least extend along the edges of the instrument tray5. Then, the instrument tray5is attached to the attachment portion4of the enclosure2so that the adhesive layer51of the instrument tray5can be aligned with the adhesive layer41of the attachment portion4.

After attachment, as shown inFIG.6B, the instrument tray5is ready to be accessed by a surgeon. As shown inFIG.6C, the surgeon inserts his or her hands into the gloves3and cuts away the wall of the enclosure2, the adhesive layer42of the attachment portion4as well as the adhesive layer52and the transparent layer53of the instrument tray5so that the medical instruments in the instrument tray5can be accessed inside the enclosure2. In some embodiments rather than having the adhesive layer extend along the edges it can cover the entire surface and when access to the tray5is needed the surgeon cuts through the layer.

FIG.6Dshows a modified version of the first embodiment where two instrument trays5,5′ are attached to the enclosure2. In this manner, the surgeon can access additional sterilized instruments in the tray5′ such as scissors, a syringe, a surgical knife and so on while keeping the surgical field sterile. Thus, the surgery can be efficiently performed while reducing the risk of contamination.

The tray5shown inFIGS.5Athough6D can be replaced in a situation where instruments in the tray first supplied are not sufficient for a procedure and additional or other instruments are needed. The method for replacing the existing tray with a new tray is as follows: First, a sterile adhesive patch located in the enclosure is applied over the incision in the transparent layer53of the instrument tray. Next, the instrument tray is removed from the exterior of enclosure by detaching it from the attachment portion4a, thereby exposing the adhesive layer42of the attachment portion. The new instrument tray that has different instruments than the instrument tray is provided. Like the original tray it has a transparent layer covering the instruments in the new tray and an adhesive on its top52covered by a protective cover51. Then; the protective cover of the new instrument tray is removed to expose its adhesive layer and the new tray is attached onto the enclosure at the attachment portion by having the adhesive of the new instrument tray contact the adhesive of the attachment portion on the outside of the enclosure, Finally, the surgeon cuts away the transparent layer53of the new instrument tray so that the different medical instruments in the instrument tray can be exposed inside the enclosure.

In the present invention, a sterile bag is utilized to store sterilized components. For instance, as shown inFIG.7, a small sterile bag101is used for containing relatively small components such as the instrument tray5. The sterile bags101must be removed before accessing the instrument tray5.FIG.8shows a large sterile bag102that is used for containing the entire surgical sterile field system100. The sterile bags101,102have an opening port103that can be pulled apart to open the sterile bags101,102.

FIG.9shows a modified version of the first embodiment where two surgeons9a,9bperform general surgery. The surgery may be performed in a hospital or an OBS or a doctor's office using the surgical sterile field system100of the present invention. However, the location is not limited to an office, but may include an open field such as a battlefield or an accident site. No matter where the operation is performed, thanks to the surgical sterile field system100, the patient is sufficiently protected from contamination.

As seen inFIG.9, two pairs of the integral gloves are provided on opposite sides of the wall of the enclosure2. Using these gloves, the surgeons have access to the surgical tools in tray or box5. In this case the surgery is performed without a microscope. In addition, the incision site7can by anywhere on the body of the patient. The shape of the enclosure may be folded or otherwise adjusted (e.g., changed in size or shape) to fit the part of the body that is being operated on.

FIG.10illustrates the process of attaching the enclosure2to the incision site7. Similar to the process described above, first the cover layer41of the attachment portion of the enclosure2is peeled off. Then, the enclosure2is lowered so that the adhesive layer of the attachment portion is placed over the incision site7of the patient8. Then, the enclosure2is attached directly to the area around the incision site7. After attachment, the surgeon can simultaneously cut away and remove a portion45of the wall of the enclosure2and a part of the attachment portion4that is surrounded by the adhesive layer42so that the incision site7is accessible. The removed portion of the enclosure2and the attachment portion4may be left inside the enclosure2. In this manner, the surgeon can perform a surgery while minimizing the risk of contamination to the incision site7. When performing ocular surgery, it is preferrable that the adhesive extend about the periphery of the incision site. In general surgery, e.g., chest surgery as shown inFIG.10, it may be preferable to have the adhesive extend over the entire area and be sealed to the patient's chest. Rather than cut out the portion45the surgeon can leave it in place and make an incision directly through the enclosure and adhesive at the incision cite. Once the operation is complete, the wound can even be sutured while the adhesive layer is still adhering to the patient's chest. In such a situation it is beneficial to include an antibiotic or other medicine in the adhesive to guard against infection and to promote healing.

FIG.11is a second embodiment of the present invention. In this embodiment the microsurgical sterile field system200differs from the system100of the first embodiment in the presence of an internal magnifying glass40. The magnifying glass40is aligned with the incision site7and configured to magnify the incision site7. Further, there can be a modified version of the second embodiment where the entry port6for the enclosure is omitted.

FIG.13shows a prior setup for inserting a medical device, for example an insertable cardiac monitor, or medicine in a cavity formed in the body of a patient, e.g., in the patient's chest. In this out-patient setting, the surgeon9wears a mask, gloves, and a gown. A drape is 70 placed over the patient. It can pass over a frame72that holds it away from the patient's face so they can breathe, but not on the surgical site. Nevertheless, having the drape over the patient's face is uncomfortable for the patient. A hole is provided in the drape at the location of the surgical site7.

An alternative arrangement for conducting the surgery depicted inFIG.13is shown inFIG.14, which represents a fourth embodiment of the present invention. In the arrangement ofFIG.14, an expanded or inflated transparent enclosure300is located over the surgical site7in the manner discussed above. Within the enclosure300there is a box5with surgical instruments that allow the surgeon to make an incision in the chest of the patient. This incision can be used to insert capsules, e.g., therapeutic time release capsules and cardiac monitors such as those sold by Medtronic, in the chest of a patient. In the case of the cardiac monitor, the instruments include an insertion tool loaded with the cardiac monitor and an incision tool in the form of a handle with a scalpel tip at its end as shown in the hands of the surgeon inFIG.14. The technique for insertion of the monitor is shown on the Medtronic website. However, this procedure can be conducted in an ordinary room without special sterilization and filtering. Further, the surgeon need not wear a mask, glove, and gown. Nevertheless, the surgical site7is protected from infectious materials, while allowing the patient to breathe normally without a drape over his face. As shown by the manufacturer of the Medtronic device, insertion is suggested merely with a topical disinfectant spread to the insertion site. This would not prove the type of significantly added protection from infection provided by the present invention.

As shown inFIG.15, which is a plan view of the enclosure300ofFIG.14, the surgical instrument and other instruments needed for the procedure are pre-sterilized and located in the surgical box or tray5within the enclosure300. Typical instruments for implantation in the chest wall are the inserter54and an incision tool56for creating an opening in the skin of the chest. As can be seen there is an incision site7that is a portion of the enclosure, and it can have adhesive along its periphery7athat allows it to be fixed to the skin of the patient. Once in place, the surgeon can cut through the enclosure with a scalpel from the instrument tray5to expose the tissue of the patient where the chest insertion is to take place. There is a filter30, such as a HEPA filter, through which air may be drawn into or pushed into the enclosure by a fan or a sterile pump (not shown) to keep the enclosure inflated during the procedure.

A fourth embodiment is shown inFIG.16. In that figure an enclosure400is used to isolate the pelvic area of a patient undergoing a catheter insertion procedure, where a cardiac catheter75is placed in a pelvic vein. The catheter enters the enclosure400through a sealed tube402. This tube allows the catheter to be moved into or withdrawn from the enclosure without allowing surrounding atmosphere to enter the enclosure. Thus, it may be similar to or the same as port20inFIG.2. Once the catheter is placed in the vein it is pushed through the vein to the heart. A machine76is connected to the end of catheter outside of the enclosure and provides the capability for the catheter to carry out its prescribed function, e.g., to expand in a clogged artery when the catheter carries a stent. The enclosure400has an adhesive along its base which is covered by a release strip. When ready for use the release strip is removed and the enclosure is fastened to abdomen and upper thighs of the patient completely covering the pelvic areas surrounding the surgical site.

In the arrangement ofFIG.17Athe enclosure the enclosure400ofFIG.16further includes a frame410to keep the enclosure in an expanded shape. This frame can be used in addition to air inflation of the enclosure or in place of it. If force air is not needed or desired, certain benefits are achieved. First, the cost of the equipment for air inflation is eliminated. This includes a fan and any filter system. Second, the noise of the fan is eliminated. Third, the possibility is removed that the air insertion equipment will block the view of the patient by the surgeon.

Preferably the frame410is made from flexible spokes411with feet412at one end. The other ends of the spokes are attached to an apical ring or disk413at the top of the frame. The frame parts can be thin flexible plastic or spring metal rods. In one version the frame is made collapsible as shown inFIG.17B. To assist in making the frame collapsible, spring-loaded hinged joints416are provided in each of the spokes of the frame.FIG.17Bshows the frame in its collapsed form. The enclosure400is also collapsed when the frame is collapsed. It can be stacked and shipped in this collapsed shape after its interior has been sterilized. When it is time to use the enclosure400, the surgeon can pull up on a loop415, allowing the springs in the hinged joints to cause the frame to pop-up into its expanded shape.

According to the surgical sterile field system of the present invention, it is possible to improve the efficiency of the creation of a sterile surgical site so that surgical procedures can be performed in a doctor's office. The surgery can be in different parts of the body, e.g., the eye, the chest and the pelvic area. Further, it is possible to suppress the cost associated with the procedures since the surgical sterile field system of the present invention does not require a significant amount of sterilization of the operating site. In addition, it is possible to reduce the risk of contamination that may occur in out-patent and OBS procedure rooms. Therefore, the present invention has industrial benefit and applicability.
