CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application is a non-provisional application of U.S. Provisional Application No. 61/745,426, Attorney Docket No. 358, filed on Dec. 21, 2012, which is incorporated herein by reference in its entirety. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention relates generally to medical devices, and more particularly to endo-cutters or micro-cutters and stapling systems for performing various surgical procedures. 
       BACKGROUND 
       [0003]    Traditionally, surgeons use sutures to close wounds and incisions, attach separate tissue structures to one another, and perform other medical or surgical functions during various surgical procedures or operations. However, proper suturing requires significant skills to perform; in particular, complex suturing procedures can be time-consuming and/or very difficult to perform effectively. Furthermore, suturing may be impractical or unfeasible in certain situations. For example, suturing may be very difficult to perform in minimally-invasive surgical procedures where suturing tools may be required to be inserted through a small opening (often referred to as an access port) to gain access into a patient&#39;s body, and then the suturing operation is performed through the small access opening with extension tools to suture the target tissue. In such minimally-invasive surgical procedures, the opening or access port to the surgical site inside the patient may not be large enough to allow effective maneuvering of suturing tools to perform the suturing procedure efficiently and effectively. If access ports were made larger to allow for easier suturing operations, the benefits of minimally-invasive surgery, however, may be significantly reduced or altogether eliminated. Indeed, as surgical technology continues to progress, the size of the access ports required to access surgical sites in the body to perform minimally-invasive procedures correspondingly continues to decrease. Presently, micro-laparoscopy typically utilizes instruments with diameter of about 2 millimeters to about 3 millimeters to perform complex operations; e.g., laparoscopic cholecystectomy and inguinal hernia repair. When instruments of such small diameters are used, the size of the access ports can also be very small. It is common that the access ports can be as small as about 2 millimeters to about 3 millimeters in diameters. The benefits of these advances in surgical technology to the patients are obvious, minimally-invasive procedures can cause less physical trauma to the patient. As such, these minimally-invasive procedures can be performed to greater percentage of patients even if they are not in the best physical condition. In addition, because there is generally less physical trauma involved, the patients may experience less discomfort, the recovery time is typically reduced, and there may be less scarring at the operation site. However, because of restricted access, it can be significantly difficult or even impossible sometimes to perform effective suturing within a patient&#39;s body through these small access ports in minimally-invasive procedures. As such, alternatives to suturing are highly desired. 
       SUMMARY 
       [0004]    The present disclosure relates generally to medical devices, and more particularly to endo-cutters or micro-cutters and stapling systems for various surgical procedures. As disclosed, a surgical stapling apparatus is configured to perform stapling and/or cutting operations on a target tissue of a patient. The surgical stapling apparatus comprises of a mode selection switch mechanism to place the apparatus in either a clamping operational phase or a deployment operational phase. In the clamping operational phase, various clamp components are operated to facilitate loading of surgical staples into the stapling apparatus, if staples are not preloaded, placement of the stapling apparatus to a target surgical site, and clamping of target tissue to be stapled and/or cut. In the deployment operational phase, various deployment components are operated to staple and/or cut the target tissue to one or more desired distance intervals to achieve the desired surgical outcome for the patient. 
         [0005]    To describe some of the operational details, for example, the surgical stapling apparatus includes a clamp spool member that is coupled to a jaw or stapling assembly (e.g., through a clamp strip, etc.) to execute various clamping operations to prepare the surgical stapling apparatus for deployment (e.g., stapling and/or cutting of target tissue of a patient). The clamping operations include placing the jaw or stapling assembly into various clamping modes. A clamp slide member is coupled to the clamp spool member to drive or move the clamp spool member for various clamping operations. The surgical stapling apparatus also includes deployment spool member to operate or drive various components (e.g., a wedge element to deploy staples, a knife element to cut tissue, etc.) to execute various deployment operations (e.g., deployment of staples, cutting of tissue, etc.). A deployment slide member is coupled to the deployment spool member to drive or move the deployment spool member to execute various deployment operations. 
         [0006]    A mode switch mechanism or a mode switch member selectively places the surgical stapling apparatus in either a clamping operational phase or a deployment operational phase. 
         [0007]    Operation of a trigger mechanism or a trigger member operates the mode switch mechanism or the mode switch member to selectively place the surgical stapling apparatus in either the clamping operational phase or the deployment operational phase. 
         [0008]    When in the clamping operational phase, operation of the trigger member operates the components to execute the various clamping functions. The various clamping functions include placing the surgical stapling apparatus and/or the stapling assembly in a first mode or a trocar mode, a second mode or an open mode, a third mode or a clamping mode, etc. 
         [0009]    When in the deployment operational phase, operation of the trigger member operates the components to execute various deployment functions. The various deployment functions include stapling certain amount of target tissue or stapling a target tissue for a certain distance interval. In addition, the various deployment functions include cutting certain amount of target tissue or cutting a target tissue for a certain distance interval. 
         [0010]    The surgical stapling apparatus also includes a clamp lock member configured to place or lock the surgical stapling apparatus in various clamping modes. For example, the surgical stapling apparatus includes a clamp slide pin member coupled to the clamp slide member configured to engage with a clamp lock member to place or lock the surgical stapling apparatus in various clamping modes. The clamp lock member includes a first feature to engage with the clamp slide pin member to place or lock the surgical stapling apparatus in a first mode or a trocar mode. The clamp lock member includes a second feature to engage with the clamp slide pin member to place or lock the surgical stapling apparatus in a second mode or an open mode. The clamp lock member includes a third feature to engage with the clamp slide pin member to place or lock the surgical stapling apparatus in a third mode or a clamping mode. 
         [0011]    The surgical stapling apparatus also includes a clamp lock release member coupled to the clamp lock member that operates to adjust an angular position or orientation of the clamp lock member to allow release of the clamp slide pin member in a locked position to disengage from one of various clamping modes. 
         [0012]    As described from above, the surgical stapling apparatus is configured to perform surgical treatments to a target tissue by operating a trigger member of the surgical stapling apparatus to activate a clamp gear combination, asserting a first trigger-force to place a stapling member in a first mode or trocar mode, asserting a second trigger-force to place the stapling member in a second mode or an open mode, asserting a third trigger-force to place the stapling member in a third mode or a clamp mode, activating a mode selection switch to select a deployment phase; and asserting one or more deployment forces to execute one or more deployment operations. Additionally, asserting a release force to a clamp release member to change an orientation of a clamp lock member to release the stapling member in the first mode or trocar mode, the second mode or open mode or the third mode or clamp mode. 
         [0013]    Furthermore, the surgical stapling apparatus is configured to perform surgical treatments to a target tissue by operating a trigger member of the surgical stapling apparatus to activate a clamp gear combination, asserting a first trigger-force to drive a clamp spool member and a clamp slide member combination to place a stapling member in a first mode or trocar mode, asserting a second trigger-force to drive a clamp spool member and a clamp slide member combination to place the stapling member in a second mode or an open mode, asserting a third trigger-force to drive a clamp spool member and a clamp slide member combination to place the stapling member in a third mode or a clamp mode, activating a mode selection switch to select a deployment phase; and asserting one or more deployment forces to drive a deployment spool member and a deployment slide member combination to execute one or more deployment operations. Additionally, asserting a release force to a clamp release member to change an orientation of a clamp lock member to release the stapling member in the first mode or trocar mode, the second mode or open mode or the third mode or clamp mode. The act of changing the orientation or position of the clamp lock member allows a clamp slide pin to disengage from an engaging feature of the clamp lock member.

     DETAILED DESCRIPTION 
       [0034]      FIG. 1  illustrates examples of endo-cutter or micro-cutter and stapling systems  100  that can be alternatives or replacements to suturing. In particular, these endo-cutter or micro-cutter and stapling systems  100  are especially useful as alternatives or replacements to suturing in minimally-invasive surgical procedures. As illustrated in the figure, the operation of cutting and stapling is performed through a long slim shaft  104 . The actual operations of clamping, cutting, and stapling of tissue are performed at the distal-end  106  of the shaft  104 , and the control operations of these procedures are performed at the handle assembly  102 . The distal-end  106  may include a stapling system comprising of a staple channel and a staple anvil, which are illustrated in  FIG. 1 . The staple channel may include a staple holder or a staple cartridge for holding staples. The staple anvil deforms the staples as they are deployed. As the staples are deployed, the staples pierce the target tissue and the staple anvil deforms the staples to secure the staples against the target tissue. Further illustrated, the shaft at the distal-end may be substantially flexible and may be articulated. For example, near the distal-end of the shaft may include an articulated section  108 . Various versions of the endo-cutter or micro-cutter stapling systems may have non-articulated rigid shafts, while other versions may include substantially flexible or flexible portions that can be articulated. These and other features allow such examples of endo-cutter or micro-cutter and stapling systems (e.g., MICROCUTTER XPRESS™ and MICROCUTTER XCHANGE™, which are designed and manufactured by Cardica Inc. of U.S.A.) to be ideally suited as alternatives or replacements to suturing.

         [0035]      FIG. 2A  through  FIG. 2C  illustrate exposed and exploded views of the body, handle, and trigger elements of one example of endo-cutter or micro-cutter and stapling system  100  handle assembly  102  where the clamp and deployment mechanisms (e.g.,  310  and  1010  in  FIG. 2A ) are illustrated. In addition, some of the piece-part components of the handle assembly  102  are separately marked with reference numerals for ease of illustration and discussion, as pertain to and illustrated in  FIG. 2B  and  FIG. 2C . For ease of discussion and additional reference, component or parts identification to the referenced numerals associated with  FIG. 2B  are: (1)—Release; (2)—Pin (Release); (3)—Spring (Mode Button); (4)—Pin (Release Spring); (5)—Handle (Right); (6)—Handle (Left); (7)—Pin (Clamp Lock); (8)—Pin (Clamp Slide); (9)—Spring (Trigger); (10)—Spring (Release); (11)—Clamp Lock; (12)—Clamp Lock Tab; (13)—Deployment Pulley; (14)—Pin (Deployment Pulley); (15)—Pin (Gear); (16)—Slide (Clamp); (17)—Slide (Deployment); (18)—Washer (Gear); (19)—Clamp Pulley &amp; Gear; (20)—Deploy Pulley &amp; Gear; (21)—Cable Deploy; (22)—Cable Clamp; (23)—Trigger Subassembly; (24)—Adhesive; and (25)—Grease. For ease of discussion and additional reference, component or parts identification to the referenced numerals associated with  FIG. 2C  are: (1)—Mode Button; (2)—Spring (Ratchet); (3)—Ratchet; (4)—Spring (Trigger Clamp Gear); (5)—Trigger Gear (Deploy); (6)—Trigger Gear (Clamp); (7)—Spring (Trigger Deploy Gear); (8)—Trigger (Left); (9)—Trigger (Right); and (10)—Adhesive. 
         [0036]    As can be depicted from the  FIG. 2A ,  FIG. 2B , and  FIG. 2C , the system includes a trigger  302  in the handle assembly  102  to activate the gear system  300  (as indicated in  FIG. 3A ) that in turn operate either the clamp or deploy mechanisms (e.g.,  310 ,  1010 ), depending on which operational mode is selected by a mode switch mechanism  910 ,  912  (as illustrated in  FIG. 9A ,  FIG. 9B , and  FIG. 11 ). 
         [0037]      FIG. 3 ,  FIG. 4 , and  FIG. 5  illustrate the clamp mechanism components  310  without the body and handle cover of the endo-cutter or micro-cutter and stapling system  100  for ease of illustration and discussion. As can be appreciated from the figures, the trigger member  302  activates a set of clamp gears  300  which in turn pulls on a clamp cable member  322  that asserts a pull force onto a clamp slide member  332  and clamp spool member  342  combination. To be discussed in further detail, as the clamp slide member  332  and clamp spool member  342  combination is either pulled back by the clamp cable member as may be appreciated from the illustration of  FIG. 3  or pushed forward by a spring member  412  as illustrated in  FIG. 4 , the position of the slide member  332  and spool member  342  combination may be locked into various clamping mode positions (e.g., first mode, second mode, or third mode) by the clamp lock member  512  as illustrated in  FIG. 5 . The slide member  332  and spool member  342  can be locked in various positions as a clamp slide-pin member  522  travels either backward (as pulled by the cable member  322 ) or forward (as pushed by the spring member  412 ) along the clamp lock member  512 . The clamp slide-pin  522  may rest on the clamp lock member  512  or in the various notches or detents (e.g.,  513 ,  523 , etc.) that are on the clamp lock member  512 . The combination of the slide member  332 , spool member  342 , and clamp slide-pin member  522  are configured to operate in concert to hold the jaws (e.g., the staple channel and staple anvil) of the stapling member  106  in various operational modes or positions—such as, a first mode or trocar mode, a second mode or open mode, or a third mode or clamping mode (the stapling member of the distal-end  106  is illustrated in  FIG. 1 ). 
         [0038]    As illustrated in  FIG. 5 , the clamp slide-pin member  522  is resting near the tip of the clamp lock member  512  (e.g., in a first mode or trocar mode), not in any one of the notches or detents (e.g.,  513 ,  523 ). These various clamp modes (e.g., first mode or trocar mode, second mode or open mode, or third mode or clamping mode, etc.) are associated with various clamp operational modes of the clamp member  106  or stapling member  106  located at substantially the distal portion of the long slim shaft  104  of the endo-cutter or micro-cutter and stapling system  100  as illustrated in  FIG. 1 . 
         [0039]    Typically, in a first state or neutral state, the clamp mechanism components  310  set the clamp or stapling member  106  in a first mode or trocar mode. In this mode, the jaws of the clamp member  106  of the cutter and staple system  100  may be in a smallest or most compact configuration, which allows it to be inserted through a small opening or access port for executing cutting and stapling procedures in minimally invasive surgical operations. As mentioned previously, for example, the clamp  106  may be comprised of stapling jaw components including a staple channel (with a staple holder or staple cartridge) and a staple anvil. As can be observed in  FIG. 6 , the slide member  332  is substantially at its most extended position and the clamp slide-pin member  522  is positioned or resting at substantially the tip of the clamp lock member  512 . Also, the trigger member  302  is in its released-state or extended-state, ready to be use—such as ready to be squeezed or activated by a surgeon. 
         [0040]    The clamp mechanism components  310  are activated by a partial-squeeze of the trigger member  302 , as illustrated in  FIG. 7 . The partial-squeeze of the trigger member  302  activates the clamp gears  300  to rotate and asserts a pull force onto the slide member  332  to slide backwards toward the proximal portion of the cutter and stapling system  100 . As illustrated in  FIG. 7 , the slide member  332  has been pulled back and the clamp slide-pin member  522  is resting in a first notch or first detent  513  on the clamp lock member  512 . The backward movement of the slide member  332  asserts a pull force on the components of the jaws of the clamp (e.g., stapling members: staple channel and staple anvil—not shown) which causes the jaws of the clamp to open in this second mode or open mode. In this second mode or open mode, staples or staple cartridges can be loaded into the clamp or stapling system (e.g., staple channel &amp; staple cartridge combination). Also, after the cutting and stapling system is inserted into the target operational site, in the second mode or open mode, the clamp ( 106 ) can be positioned to grasp tissue for stapling. Further illustrated in  FIG. 7  is that a clamp pin-release member or clamp lock release member  524  is in a second-level position in a substantially triangular slot  533  or the first slot  533 , on the clamp lock member  512 , as compared to a first-level position, when the clamp mechanism components  310  are in a first mode or trocar mode as illustrated in  FIG. 6 . The clamp pin-release member  524  in a second-level position may cause the clamp lock member  512  to be in a substantially angular orientation as compared to the clamp release-pin  524  in a first-level position. Alternatively, the clamp pin-release member  524  in a second-level position may cause the clamp lock member  512  to be in a substantially greater angular orientation as compared to the pin-release member  524  in the first-level position. When the clamp release-pin  524  is in the first-level position, the clamp lock member  512  may be oriented in a substantially horizontal orientation. Whereas, when the clamp release-pin  524  is in the second-level position, the clamp lock member  512  may be oriented in a slightly or substantially angular orientation or in a substantially non-horizontal orientation. 
         [0041]      FIG. 8  illustrates the clamp mechanism  310  components in a third mode or clamping mode as caused by a full-squeeze or full-activation of the trigger member  302 . The full-squeeze of the trigger member  302  further advances the clamp gears  300  that winds up the cable member  322 , which further pulls the slide member  332  and spool member  342  combination backwards further towards the proximal portion of the cutter and stapling system  100 . The backward movement of the slide member  332  causes the clamp slid-pin member  522  to travel into a second notch or second detent  523  of the clamp lock member  512 . In this mode, the spool member  342  which connects or couples to the components of the jaws of the clamp  106  (e.g., stapling members) causes the jaws of the stapling members  106  to clamp onto the tissue that is ready to be stapled. In this position, in the second notch or second detent  523 , the jaws are secured or locked in clamping mode. Further illustrated in  FIG. 8 , the pin-release member  524  is in a third-level position. In this third-level position, the clamp lock member  512  is at a substantial angular orientation, in which the clamp lock member has pivoted about a clamp pin-lock member  702  in a third notch or third detent  543 . In this position, the clamp lock member  512  securely holds the clamp slide-pin  522  in the second notch or second detent  523  of the clamp lock member  512 . To release the jaws of the clamp or the stapling member  106 , the clamp lock member  512  can be moved to “unlock” or “release” the clamp slide-pin member  522  from the second notch or second detent  523  by adjusting or pushing forward the pin-release member or clamp lock release member  524  in the triangular slot  533 . The releasing adjustment or movement of the pin-release member  525  causes the clamp lock member  512  to move or position itself in a substantially “opposite” angular orientation, which allows the clamp slide-pin member to be released from the second notch  523  as the spring member  412  pushes the clamp spool member  342  and clamp slide member  332  forward. Similarly, the clamp slide-pin member  522  can be released from the first notch  513  in a substantially similar manner. 
         [0042]    With the clamp mechanism  310  is in the third mode and target tissue is clamped, the next phase of the operation is ready to be deployed.  FIG. 9A  and  FIG. 9B  illustrate a backside view of an endo-cutter or micro-cutter and stapling system  100  where a mode switch mechanism  910  and a mode selection member  912  are illustrated. A stand-off member  902  is shown to engage the clamp gears  300  that drive the clamp mechanism  310 . 
         [0043]      FIG. 10  illustrates the deploy mechanism components  1010  that are used to deploy or drive an endo-cutter or micro-cutter  100  to cut target tissue. Cutting and stapling of target issue may occur at substantially the same time or the operations may be separated by a substantially small time incremental period. As illustrated in  FIG. 10 , the deploy mechanism  1010  comprises of a set of deploy gears  1030 , a deployment cable member  1022 , a combination of deployment slide member  1032  and a deployment spool member  1042 , and a deploy pulley member  1052 .  FIG. 11  illustrates a backside-view of an endo-cutter or micro-cutter and stapling system where a mode switch mechanism  910  has been activated to place the endo-cutter or micro-cutter and stapling system  100  in a deployment mode. For example, a mode switch button  912  has been pushed or activated to move the stand-off member  902  of the mode switch mechanism  910  to engage the gears  1030  of the deploy mechanism  1010 , while disengaging with the clamp drive gears  300  of clamp mechanism  310 . Once the deploy mechanism  1010  is engaged, activation of the trigger member  302  activates the gears  1030  of the deploy mechanism  1010  which advances or drives the endo-cutter or micro-cutter  100  to cut target tissue. Additionally, the deployment mechanism  1010  may also advances or drives the endo-cutter or micro-cutter  100  to staple target tissue. 
         [0044]      FIG. 12A  and  FIG. 12B  illustrate the deployment mechanism components of the endo-cutter or micro-cutter and stapling system in a deployment mode; for example, in a condition ready to deploy an endo-cutter or micro-cutter. As illustrated in  FIG. 12B , a deploy ratchet member  1212  engages a first tooth  1242  of a first deploy gear  1214 .  FIG. 13A  and  FIG. 13B  illustrate the deployment mechanism components of the endo-cutter or micro-cutter and stapling system in a first deployed mode; for example, a first trigger-squeeze in the deployment mode. As the trigger member  302  is squeezed or activated, the deploy ratchet member  1212  urges or advances the first deploy gear  1214 , as illustrated in  FIG. 13B . The first deploy gear  1214  acts on a second deploy gear  1216  which winds and pulls on a deploy cable member  1222 . The deploy cable member  1222  pulls on the combination of deploy slide member  1032  and deploy spool member  1042  to advance the combination to a first deployed position, illustrated in  FIG. 13A . The movement of the combination advances the components associated with the endo-cutter or micro-cutter (such as a deployment strip member  1252 , a knife member (not shown), etc.) to a first position; cutting targeted tissue to a certain distance or interval. Additional deployment members may also be activated, such as a wedge member (not shown) to drive and deploy staples in the clamp member  106  to correspondingly staple the targeted tissue to a certain distance or interval. 
         [0045]      FIG. 14A  and  FIG. 14B  illustrate the deployment mechanism components of the endo-cutter or micro-cutter and stapling system in a second deployed mode; for example, a trigger-release state after the first deployed mode. In  FIG. 14A , it is illustrated that the trigger member  302  is released, which causes the deploy ratchet member to return or retreat and engages the second tooth  1244  of the first deploy gear  1214 . In this position, the deploy mechanism  1010  is ready for further deployment. 
         [0046]      FIG. 15A  and  FIG. 15B  illustrate the deployment mechanism components of the endo-cutter or micro-cutter and stapling system in a third deployed mode; for example, a second trigger-squeeze after the second deployed mode. As illustrated in  FIG. 15A , the trigger member  302  is squeezed to advance the first deploy gear  1214 , which is illustrated in  FIG. 15B . The advancement or rotation of the first deploy gear advances or rotates the second deploy gear  1216  in an opposite direction, which winds or pulls on the deploy cable member  1222 . The deploy cable member  1222  winds around a deploy pulley  1052  and pulls the combination of deploy slide member  1032  and deploy spool member  1042 . The deployment member combination ( 1032  and  1042 ) is moved forward or advanced to a second deployed position, as illustrated in  FIG. 15A . The movement of the deployment member combination ( 1032  and  1042 ) advances or drives the components associated with the endo-cutter or micro-cutter further forward (e.g., a deployment strip member  1252 , a knife member (not shown), etc.), thus further cutting the targeted tissue. Additional deployment members may also be activated, such as a wedge member (not shown) to drive and deploy staples in the clamp member  106  to correspondingly staple the targeted tissue to a certain distance or interval. 
         [0047]      FIG. 16A  and  FIG. 16B  illustrate the deployment mechanism components of the endo-cutter or micro-cutter and stapling system in a fourth deployed mode; for example, a trigger-release state after the third deployed mode. As illustrated in  FIG. 16A , the trigger member  302  is released, which allows the deploy ratchet member  1212  to return or retreat. The return of the deploy ratchet member  1212  allows it to engage a third tooth  1246  on the first deploy gear  1214 . The engagement of the deploy ratchet  1212  with the third tooth  1246  on the first deploy gear  1214  may provide sufficient adjustments to the engagement of the mode switch mechanism  910  to allow it to reset. For example, the adjustment may allow the mode switch mechanism  910  and/or the mode switch selection member  912  to reset or reengage the mechanisms and components of deploy and clamp operations to the first mode (e.g., clamp mechanism first mode). 
         [0048]    The adjustment and engagement of the mode switch mechanism  910  and/or the mode switch selection member  912  may be triggered by the third tooth pushing on the deployment ratchet  1212  as the ratchet engages with the third tooth  1246 . The third tooth  1246  may be irregular-shaped or has a shape that is substantially different than the shape of the first tooth and/or second tooth of the first deploy gear  1214 . The mode switch mechanism  910  may be spring-loaded, such that the engagement of the deploy ratchet  1212  with the third tooth  1246  provides sufficient adjustment or movement to allow the spring-loaded mode switch mechanism  910  to reset. The resetting of the mode switch mechanism allows the stand-off  902  member to return to a position where the clamp gears  300  of the clamp mechanism  310  is engaged and in state of the first mode (clamp mechanism first mode), as illustrated in  FIG. 17A  and  FIG. 17B . 
         [0049]      FIG. 17C  and  FIG. 17D  illustrate side-views of the endo-cutter or micro-cutter and stapling system  100  illustrating that the mode switch mechanism  910 ,  912  has been reset to place the endo-cutter or micro-cutter and stapling system  100  in the first mode or trocar mode. As may be appreciated from the illustrations, the clamp slide pin member  522  is positioned or resting near the tip of the clamp lock member  512 . Also, the clamp pin-release member  524  is positioned or resting in the first-level position in the substantially triangular-shaped slot  533  in the clamp lock member  512 . The first-level position may allow the clamp lock member  512  to be in a substantially horizontal level, orientation, or position. 
         [0050]      FIG. 18A  and  FIG. 18B  illustrate the deploy mechanism components in a deployed state illustrating that components or accessories (e.g., endo-cutter or micro-cutter) attached or coupled to the deploying components have been deployed or advanced to their deployed state. For example, an endo-cutter or micro-cutter may be coupled to the deploy mechanism  1010  (such as by way of the deployment slide member  1032  and deployment spool member  1042 ). As the deploy mechanism components are advanced in various modes, the endo-cutter or micro-cutter is correspondingly advanced forward to cut target tissue as part of the clamping, cutting, and stapling of the endo-cutter or micro-cutter and stapling system operations.
