Full Description:
FIELD OF THE INVENTION  
       [0001]     The present invention relates to a medical instrument, in general, and to a hemostasis apparatus for preventing profuse bleeding, particularly during a surgical procedure.  
       BACKGROUND OF THE INVENTION  
       [0002]     In performing many medical procedures, it is necessary to make incisions. It is just as necessary to properly close the incision. Physicians would have experienced profuse bleeding while performing cutaneous or subcutaneous surgery on a patient. The profuse bleeding will cause numerous complications that will raise the risk of the surgery.  
         [0003]     In prior instances, a physician would utilize a tourniquet, hemostatic cotton or a hemostat to prevent profuse bleeding of a patient during a surgical procedure. But the efficiency of the hemostasis is not quite satisfying, owing to the physical restraints of the above-mentioned devices. For instance, the tourniquet is not suited for a surgery on a human chest. Therefore, a new hemostasis apparatus could serve to rectify this problem.  
       SUMMARY OF THE INVENTION  
       [0004]     An object of the present invention is to provide a hemostasis apparatus for preventing bleeding during cutaneous or subcutaneous surgeries.  
         [0005]     Another object of the present invention is to provide a hemostasis apparatus for helping surgeries go more smoothly and safely.  
         [0006]     A further object of the present invention is to save time and effort during surgeries.  
         [0007]     Yet another object of the invention is to provide an economical and practical means to more easily facilitate surgery.  
         [0008]     Other objects and advantages of the present invention will become apparent from the following descriptions, taken in connection with the accompanying drawings, wherein, by way of illustration and example, four embodiments of the present invention are disclosed.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0023]      FIG. 1   a  is a plan view of an embodiment of the present invention. Referring now to  FIG. 1   a , the hemostasis apparatus  100  is used to control bleeding while performing a surgery on a surgical area of a patient. The hemostasis apparatus  100  includes a first portion  101  having a closed structure, a second portion  103  and  105 , and an adjusting device  107 . In this embodiment, the first portion  101  is embodied as a ring  101 , the second portion  103  and  105  are embodied as two arcs  103  and  105 , respectively, and the adjusting device  107  is embodied as four screws  107 . The hemostasis apparatus  100  of this embodiment is preferably applied to a round surgical area of a patient, for instance, a breast. Before performing a surgical operation (either cutaneous or subcutaneous) on a breast of a patient, first the physician disposes the ring  101  on the patient to surround the breast and then affixes the ring  101  to the patient in order to maintain the relative position between the ring  101  and the patient. Second, the physician adjusts the adjusting device (or the four screws)  107  to an appropriate position to make the two arcs  103  and  105  support and stress the breast to control bleeding during the surgery. The foregoing appropriate position is determined according to different surgeries and necessities of bleeding control.  
         [0024]     Referring to  FIG. 1   b , in this embodiment, the frame shape of the first portion  101  is not circular. For precisely fitting, different patients&#39; body shapes, the shape of the first portion  101  could be customized. Referring to  FIG. 5 , the hemostasis apparatus  100  is applied on a breast of a patient. The shape of the first portion  101  is designed according to the patient&#39;s breast and her body shape. Therefore, the hemostasis apparatus  100  can be perfectly disposed on the surgical area of the breast and provide trustable stability between the patient and the hemostasis apparatus itself during operation. By similar way, at the outset the physician disposes the first portion  101  on the patient to surround the breast, and then affixes the first portion  101  to the patient in order to maintain the relative position between the first portion  101  and the patient. Then the physician adjusts the adjusting device (or the four screws)  107  to a appropriate position to make the second portions  103  and  105  support and stress the breast to control bleeding from a cut  53  made during the surgery.  
         [0025]     Referring now to  FIG. 2   a , the hemostasis apparatus  200  is used to control bleeding while performing a surgery on a surgical area of a patient. The hemostasis apparatus  200  includes a first portion  201  having a closed structure, a second portion  203  and  205 , and an adjusting device  207 . In this embodiment, the first portion  201  is embodied as a rectangular frame  201 , the second portion  203  and  205  are embodied as two support devices  203  and  205 , respectively, and the adjusting device  207  is embodied as four screws  207 . The hemostasis apparatus  200  of this embodiment is preferably applied to a rectangular surgical area of a patient, for instance, an arm or a leg. Before performing a surgical operation (either cutaneous or subcutaneous) on an arm (or a leg) of a patient, the physician first disposes the rectangular frame  201  on the patient to surround the arm (or the leg), and then affixes the rectangular frame  201  to the patient in order to maintain the relative position between the rectangular frame  201  and the patient. Second, the physician adjusts the adjusting device (or the four screws)  207  to an appropriate position to make the two support devices  203  and  205  support and stress the arm (or the leg) to control bleeding during the surgery. The foregoing appropriate position is determined according to different surgeries and necessities of bleeding control.  
         [0026]     Referring to  FIG. 2   b , in this embodiment, the frame shape of the first portion  201  is hexagonal rather than rectangular. For precisely fitting different patients&#39; body shapes (or limb shapes), the shape of the first portion  201  could be customized. Referring to  FIG. 2   c , the hemostasis apparatus  200  is applied on an arm of a patient. The shape of the first portion  201  is designed according to the patient&#39;s arm shape. Therefore, the hemostasis apparatus  200  can be perfectly disposed on the surgical area of the arm and can provide trustable stability between the patient and the hemostasis apparatus itself during operation. By a similar method, at the outset, the physician disposes the first portion  201  on the patient to surround the surgical area of the arm, and then affixes the first portion  201  to the patient in order to maintain the relative position between the first portion  201  and the patient. It should be noticed that, the first portion  201  includes a frame-adjusting device  209 , which adjusts the frame shape of the first portion  201  to help build a stable connection relationship between the first portion  201  and the arm. After the first portion  201  is arranged properly, the physician then adjusts the adjusting device (or the four screws)  207  to a appropriate position to make the second portion  203  and  205  support and stress the arm to control bleeding from a cut  211  during the surgery.  
         [0027]      FIG. 2   d  shows another embodiment of the hemostasis apparatus of the present invention. The first portion  201  is a three-dimensional structure that allows an arm of a patient to pass through the first portion  201 . The frame-adjusting device  209  here can also help the hemostasis apparatus  200  fit precisely on the arm of the patient. Therefore, the hemostasis apparatus  200  can be perfectly disposed on the surgical area of the arm and provide trustable stability between the patient and the hemostasis apparatus itself during operation. By a similar method, at the outset, the physician disposes the first portion  201  on the patient to surround the surgical area of the arm, and then affixes the first portion  201  to the patient in order to maintain the relative position between the first portion  201  and the patient. After the first portion  201  is arranged properly, the physician then adjusts the adjusting device (or the four screws)  207  to a appropriate position to make the second portion  203  and  205  support and stress the arm to control bleeding from a cut  211  during the surgery.  
         [0028]     Referring now to  FIG. 3   a , the hemostasis apparatus  300  is used to control bleeding while performing a surgery on a surgical area of a patient. The hemostasis apparatus  300  includes a first portion  101  having a closed structure, a second portion  103  and  105 , an adjusting device  107  and a resilient component  301 . The resilient components  301  are connected with the adjusting device  107  to facilitate the second portion  103  and  105  to stress the patient. In this embodiment, the first portion  101  is embodied as a ring  101 , the second portion  103  and  105  are embodied as two arcs  103  and  105 , respectively, the adjusting device  107  is embodied as four screws  107  and the resilient component  301  is embodied as a spring  301 . The hemostasis apparatus  300  of this embodiment is preferably applied to a round surgical area of a patient, for instance, a breast. Before performing a surgical operation (either cutaneous or subcutaneous) on a breast of a patient, the physician first disposes the ring  101  on the patient to surround the breast, and then affixes the ring  101  to the patient in order to maintain the relative position between the ring  101  and the patient. Second, the Physician adjusts the adjusting device (or the four screws)  107  to a appropriate position to make the two arcs  103  and  105  support and stress the breast to control bleeding during the surgery. The foregoing appropriate position is determined according to different surgeries and necessities of bleeding control. The spring  301  (or the resilient component  301 ) provides a force to facilitate the two arcs  103  and  105  to control bleeding during the surgery. After the surgery, the spring  301  can also provide a recovery force to facilitate the two arcs  103  and  105  reverting back to their original positions.  
         [0029]     Referring now to  FIG. 3   b , the hemostasis apparatus  300  is used to control bleeding while performing a surgery on a surgical area of a patient. The hemostasis apparatus  300  includes a first portion  101  having a closed structure, a second portion  103  and  105 , an adjusting device  107  and a resilient component  301 . The resilient components  301  are connected with the adjusting device  107  to facilitate the second portion  103  and  105  to stress the patient. In this embodiment, the first portion  101  is embodied as a ring  101 , the second portion  103  and  105  are embodied as two arcs  103  and  105 , respectively, the adjusting device  107  is embodied as four screws  107  and the resilient component  301  is embodied as a spring  301 . The hemostasis apparatus  300  of this embodiment is preferably applied to a round surgical area of a patient, for instance, a breast. Before performing a surgical operation (either cutaneous or subcutaneous) on a breast of a patient, the physician first disposes the ring  101  on the patient to surround the breast, and then affixes the ring  101  to the patient in order to maintain the relative position between the ring  101  and the patient. Second, the Physician adjusts the adjusting device (or the four screws)  107  to a appropriate position to make the two arcs  103  and  105  support and stress the breast to control bleeding during the surgery. The foregoing appropriate position is determined according to different surgeries and necessities of bleeding control. The spring  301  (or the resilient component  301 ) provides a force to facilitate the two arcs  103  and  105  to control bleeding during the surgery. After the surgery, the spring  301  can also provide a recovery force to facilitate the two arcs  103  and  105  reverting back to their original positions.  
         [0030]     Referring now to  FIG. 4   a , the hemostasis apparatus  400  is used to control bleeding while performing a surgery on a surgical area of a patient. The hemostasis apparatus  400  includes a first portion  201  having a closed structure, a second portion  203  and  205 , an adjusting device  207 , and a resilient component  401 .
