[0002] In the skin incision suturing process of general surgery, chest surgery, abdominal surgery and skin grafting in burns, manual sutures were generally used in the past, but now skin staplers are generally used. Staplers have the advantages of fast suturing, easy operation, and few side effects and surgical complications. However, the conventional skin staplers are basically disposable as a whole, which leads to high product costs on the one hand and generates a large amount of medical waste on the other hand. Therefore, designing a skin stapler that can be detached so that part of the structure can be reused can effectively reduce the cost of the overall stapler and reduce the amount of medical waste generated.

DETAILED DESCRIPTION

[0058] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0059] Embodiment 1:

[0060] Reference Figures 1 to 11 As shown, this embodiment provides a skin seam assembly suitable for a skin stapler, so this embodiment is directly described in detail with reference to the skin seam assembly used in the skin stapler.

[0061] Specifically, the skin stapler provided in this embodiment includes: a skin seam assembly and a shell assembly suitable for detachably cooperating with the skin seam assembly; wherein the skin seam assembly includes a staple magazine frame and a limiting protrusion 1 fixed at the front end of the staple magazine frame; the shell assembly includes an outer shell, an assembly bin formed in the outer shell for accommodating the skin seam assembly, and a limiting stopper 2 slidably engaged with the front end of the outer shell; and the limiting stopper 2 is provided with a limiting hole 21 for snap-fitting with the limiting protrusion 1.

[0062] That is to say, as the limit block 2 slides on the outer shell, when the limit block 2 slides to a certain position, the limit block 2 can engage with the limit protrusion 1 on the nail magazine frame, so that the limit block 2 can form a stopper for the leather seam component to be separated from the assembly bin in the outer shell, and the leather seam component can be firmly assembled and limited in the assembly bin in the outer shell. When the limit block 2 leaves the above-mentioned engagement position with the limit protrusion 1 and slides on the outer shell, so that the limit block 2 does not affect the position of the leather seam component to be separated from the assembly bin of the outer shell, the leather seam component can be smoothly separated from the outer shell, and the limit block 2 at this time will not interfere with the disassembly process of the leather seam component and the outer shell.

[0063] It should be noted that the "front end" and "rear end" referred to in this embodiment are specifically based on the relative position of the skin stapler during use, where the "front end" refers to the end of the skin stapler that contacts human tissue, and the "rear end" refers to the end that is relatively far away from human tissue.

[0064] Next, the outer shell is described in detail. The outer shell includes a left shell 31 and a right shell 32 that are suitable for being connected and matched, and a handle 4 that can rotate relative to the left shell 31 and the right shell 32. Specifically, the left shell 31 and the right shell 32 are matched and matched through a rotating shaft 51; wherein the rotating shaft 51 is fixedly provided on the side wall of the right shell 32 facing the left shell 31; the left shell 31 is provided with a positioning hole 52 suitable for matching with the rotating shaft 51; and the handle 4 is provided with a rotating hole 41 suitable for being sleeved on the rotating shaft 51. Under such a structure, the handle 4 can rotate around the rotating shaft 51, and the left shell 31 and the right shell 32 can achieve the positioning effect when the two are assembled under the cooperation of the rotating shaft 51 and the positioning hole 52.

[0065] Regarding the assembly and fastening between the left shell 31 and the right shell 32 of the present embodiment, in an optional implementation, the rotating shaft 51 is suitable for being partially inserted into the positioning hole 52 to achieve the matching of the rotating shaft 51 and the positioning hole 52. When the left shell 31 and the right shell 32 are aligned under the matching of the rotating shaft 51 and the positioning hole 52, welding and fixing can be used to match and fix the left shell 31 and the right shell 32. It should be noted that in this case, the end of the rotating shaft 51 matching the positioning hole 52 is provided with an annular boss 53 on the outer wall of the rotating shaft 51, and the boss 53 is used to limit the depth of the rotating shaft 51 inserted into the positioning hole 52. In another optional implementation, the rotating shaft 51 will not be directly inserted into the positioning hole 52. In this case, the rotating shaft 51 will only be aligned with the positioning hole 52, and an axial threaded hole is provided in the rotating shaft 51. When the left housing 31 and the right housing 32 are aligned under the cooperation of the rotating shaft 51 and the positioning hole 52, the fastening screw 6 can be inserted into the rotating shaft 51 after passing through the positioning hole 52 to achieve the fastening connection between the left housing 31 and the right housing 32 through the fastening cooperation between the fastening screw 6 and the rotating shaft 51. It should be noted that in this case, for the left housing 31 and the right housing 32, there are several other assembly holes between the two that can be used to assemble the fastening screws 6, that is, a plurality of fastening screws 6 are used to achieve a firm fit between the two.

[0066] In an optional implementation, the outer shell of this embodiment is matched with the limit block 2 through the following structure: strip slide grooves 7 are symmetrically provided at the front ends of the left shell 31 and the right shell 32; the length of the strip slide groove 7 is greater than the side length of the limit block 2; and pulleys 22 suitable for slidingly matching with the strip slide grooves 7 on the left shell 31 and the right shell 32 are respectively provided on a pair of opposite side edges of the limit block 2. It should be noted that the length of the strip slide groove 7 here is designed to meet the limit block 2 when it slides to one of the positions in the strip slide groove 7. It can be engaged with the limit protrusion 1 on the nail magazine frame; and when the limit block 2 slides to another position in the strip slide groove 7, it will not affect the separation of the leather seam assembly from the outer shell. It should be noted that, for the two special positions of the above-mentioned limit stopper 2, in order to quickly know that the limit stopper 2 has slid into place, the structure of the strip slide 7 designed in this embodiment satisfies the following conditions: when the limit stopper 2 slides to the top of the strip slide 7 in the strip slide 7, the limit stopper 2 will not affect the leather seam assembly from being installed into or detached from the outer shell, and when the limit stopper 2 slides to the bottom of the strip slide 7 in the strip slide 7, the limit stopper 2 is just suitable for engaging with the limit protrusion 1. In this way, the control of the movement state of the limit stopper 2 can be quickly mastered through the two "limit" positions.

[0067] Next, the nail magazine frame includes a left nail magazine 81 and a right nail magazine 82 that are connected and a chassis 83 that is connected to the left nail magazine 81 and the right nail magazine 82; and the left nail magazine 81 and the inner side wall of the left shell 31 and the right nail magazine 82 and the inner side wall of the right shell 32 are matched through a clamping structure. The chassis 83 here can be optionally assembled with the bottom of the left nail magazine 81 and the right nail magazine 82 through a clamping slot, and other structures can also be used, that is, as long as the chassis 83 and the left nail magazine 81 and the right nail magazine 82 can be matched and fixed, the use requirements of this embodiment can be met.

[0068] On the basis of the above structure, it should be noted that half protrusions 11 suitable for splicing to form the limit protrusions 1 are symmetrically arranged on the front ends of the left nail bin 81 and the right nail bin 82. Under such a structure, the limit stopper 2 can be matched and fixed with the left nail bin 81 and the right nail bin 82 at the same time.

[0069] The clamping structure for assembling the nail magazine frame and the outer shell in this embodiment adopts the following structure: the clamping structure includes guide grooves 91 respectively provided on the left nail magazine 81 and the right nail magazine 82, and guide strips 92 respectively provided on the left shell 31 and the right shell 32 suitable for clamping with the guide grooves 91; wherein the notches of the guide grooves 91 are located at the rear end side of the left nail magazine 81 and the right nail magazine 82. Under this structure, the nail magazine frame only needs to be gradually inserted into the assembly bin in the outer shell through the cooperation of the guide grooves 91 and the guide strips 92.

[0070] For the guide groove 91 and guide strip 92 suitable for matching adopted in this embodiment, firstly, the assembly is convenient, which can be realized by simple linear push-pull motion, and the assembly and disassembly efficiency is high. Secondly, the guide strip 92 provided on the housing assembly is convenient for the disinfection and sterilization process of the housing assembly, and there is no sterilization dead angle. Therefore, such a structure is convenient for the housing assembly to be thoroughly disinfected and sterilized during repeated use.

[0071] In conjunction with the accompanying drawings, an optional implementation case is described. In this embodiment, the left nail magazine 81 and the right nail magazine 82 are matched in the following manner: the left nail magazine 81 and the right nail magazine 82 are matched and fixed by a positioning buckle 84 and a positioning boss 85 suitable for snap-fitting; wherein a positioning buckle 84 is respectively provided on the upper end surface and the lower end surface of the left nail magazine 81; and a positioning boss 85 suitable for cooperating with the positioning buckle 84 is respectively provided on the upper end surface and the lower end surface of the right nail magazine 82.

[0072] In addition, it should be noted that in this embodiment, an alignment structure is further provided between the left nail magazine 81 and the right nail magazine 82; the alignment structure includes an alignment post 86 provided on the left nail magazine 81, and an alignment hole 87 provided on the right nail magazine 82 suitable for plugging and matching with the alignment post 86. During the assembly process of the left nail magazine 81 and the right nail magazine 82, the alignment post 86 and the alignment hole 87 are plugged and matched to form an alignment assembly structure 200, which can improve the assembly efficiency of the snap-fit ​​between the left nail magazine 81 and the right nail magazine 82.

[0073] Furthermore, it is necessary to explain that the skin stapler of the present embodiment further includes a staple storage cavity formed inside the left staple cartridge 81 and the right staple cartridge 82, and a staple 101 and a staple supply structure assembled in the staple storage cavity; the staple supply structure includes a staple push plate 102 arranged in the staple storage cartridge, a spring buckle 103 arranged at the rear end of the staple storage cartridge, and a push spring 104 arranged between the staple push plate 102 and the spring buckle 103; and a port for taking out the staple push plate 102 is provided at the rear end of the staple storage cartridge; and a buckle limiting groove 105 suitable for clamping and fixing the spring buckle 103 is provided in the right housing 32. Considering the firmness and stability of the cooperation between the staple supply structure and the staple cartridge frame after the staple supply structure is assembled into the staple storage cartridge, a clamping groove 107 for clamping and cooperating with the spring buckle 103 is provided in the right staple cartridge 82, that is, the cooperation between the spring buckle 103 and the clamping groove 107 makes it convenient for the skin stitching assembly to be assembled with the outer housing after the staple supply structure is connected and fixed with the staple cartridge frame. When the skin seam assembly of the skin stapler of this embodiment is assembled with the outer shell, the spring buckle 103 is just snap-fitted into the buckle limiting groove 105 .

[0074] The present embodiment provides an independent skin seam assembly, which can be separated or assembled with the outer shell, so as to meet flexible and changeable practical needs; at the same time, the present embodiment also provides a flexibly loadable and detachable nail supply structure, through which the suture nail 101 can be quickly stapling in the nail storage cavity, that is, when stapling, by disengaging the skin seam assembly from the outer shell, the spring buckle 103 is disengaged from the buckle limiting groove 105, and then the nail supply structure is removed from the nail magazine frame, so that the suture nail 101 can be quickly loaded into the nail storage cavity. After the suture nail 101 is assembled in place, the nail push plate 102, the push spring 104 and the spring buckle 103 are assembled with the nail magazine frame. After the assembly work is completed, the overall skin seam assembly is directly assembled with the outer shell through the cooperation of the guide groove 91 and the guide strip 92, and finally the skin seam assembly can be firmly assembled in the outer shell through the cooperation of the limiting block 2 and the limiting protrusion 1.

[0075] It should also be explained that, since the present embodiment realizes the snap-fitting with the limiting protrusion 1 on the skin seam assembly by the sliding of the limiting stop block 2 on the outer shell, and the limiting protrusion 1 is raised to a certain height relative to the nail magazine frame, therefore, during the sliding of the limiting stop block 2, the skin seam assembly needs to move a certain distance toward the "rear end" of the skin stapler in the outer shell to avoid the interference of the raised height of the limiting protrusion 1 with the movement of the limiting stop block 2. Therefore, the present embodiment is designed to have a recessed make way groove 42 on the side edge of the handle 4 facing the nail magazine frame, which is suitable for the nail magazine frame to be partially embedded. In this case, when the skin seam assembly is assembled into the assembly bin of the outer shell, the staple magazine frame is partially embedded in the yield groove 42 of the handle 4, so that the limiting protrusion 1 moves synchronously with the staple magazine frame toward the handle 4, so that the limiting block 2 can smoothly slide to a position suitable for engaging with the limiting protrusion 1. After the limiting block 2 slides into place, the skin seam assembly moves toward the "front end" of the skin stapler, so that the limiting protrusion 1 is just engaged with the limiting hole 21 of the limiting block 2.

[0076] In the above process, when the skin seam assembly moves a certain distance toward the "rear end" of the skin stapler to avoid the interference of the height of the limiting protrusion 1 with the movement of the limiting block 2, when the limiting block 2 slides to a position suitable for engaging with the limiting protrusion 1, the skin seam assembly is forced to move toward the "front end" of the skin stapler. The skin stapler used in this embodiment does not need to additionally design a special driving structure for moving the skin seam assembly toward the "front end" of the skin stapler, but directly utilizes the push spring 104 of the nail supply structure to achieve it. The specific principle is as follows: during the process of assembling the skin seam assembly into the outer shell, when the spring buckle 103 of the nail supply structure is engaged with the buckle limit groove 105 of the outer shell, the nail magazine frame has not yet entered the yield groove 42 on the handle 4, and the limit protrusion 1 will cause interference with the sliding of the limit block 2. Therefore, it is necessary to apply a force to the skin seam assembly by hand to continue to push the skin seam assembly toward the "rear end" of the skin stapler, so that the limit protrusion 1 forms a "yield" effect on the limit block 2 during the advancement of the nail magazine frame. In this process, since the spring buckle 103 has been stuck in the buckle limit groove 105 of the outer shell, the spring buckle 103 will no longer be synchronously advanced toward the "rear end" of the skin stapler with the nail magazine frame, thus limiting the The axial end of the push spring 104 is compressed, making it unable to move. In this case, the suture nail 101 and the nail pushing plate 102 continue to move synchronously with the nail magazine frame. During this movement, the push spring 104 will be compressed under the action of the nail pushing plate 102. With the further movement of the nail magazine frame, when the nail magazine frame is partially embedded in the yielding groove 42, the limiting protrusion 1 no longer interferes with the sliding of the limiting block 2; when the limiting block 2 slides to a position suitable for engaging with the limiting protrusion 1, at this time, the nail magazine frame can use the restoring force of the push spring 104 to enable the skin seam assembly to be pushed toward the "front end" of the skin suturer, so that the limiting protrusion 1 just enters the limiting hole 21 of the limiting block 2, thereby realizing the engaging fit between the two. In summary, this embodiment realizes the force in the process of pushing the skin seam assembly toward the "front end" of the skin stapler through the cooperation between the spring clip 103 of the nail supply structure and the clip limit groove 105 on the outer shell, avoiding the problem of adding an additional driving structure to simplify the overall structure of the skin stapler.

[0077] It should also be explained that, in the process of the skin seam assembly of the present embodiment being pushed toward the "rear end" of the skin stapler, when the end of the spring buckle 103 that is away from the buckle limit groove 105 just abuts against the alignment assembly structure formed by the plug-in cooperation of the alignment column 86 and the alignment hole 87, the skin seam assembly cannot continue to be pushed toward the "rear end" of the skin stapler, and at this time, the limit protrusion 1 no longer interferes with the sliding of the limit block 2. In other words, in the process of applying force by the hand to push the skin seam assembly toward the "rear end" of the skin stapler, when resistance is encountered and the skin seam assembly cannot be pushed forward, it means that the skin seam assembly has been pushed into place. Under such a structure, there is no need to add an additional structure for grasping the progress of the skin seam assembly pushing toward the "rear end" of the skin stapler, and it can be directly known by the feel of the hand, which not only simplifies the structure of the skin stapler but also improves the convenience of operation. The specific implementation method of the above structure only needs to design the height of the limiting protrusion 1 relative to the nail magazine frame to be equal to or slightly smaller than the distance between the end of the spring buckle 103 away from the buckle limiting groove 105 when the limiting protrusion 1 and the limiting block 2 are engaged and the alignment assembly structure.

[0078] Finally, it should be noted that the skin stapler of the present embodiment also includes a staple plate 106 suitable for cooperating with the handle 4, which is a maturely used skin stapler in the prior art. The staple plate 106 is suitable for pushing the suture staple 101 so that the suture staple 101 can be fired under the action of the handle 4 and the staple plate 106; and the staple plate 106 is also equipped with a return spring 108, one end of the return spring 108 is against the staple plate 106, and the other end is against the staple magazine frame. In the process of the staple plate 106 firing the suture staple 101, the return spring 108 is compressed and deformed, and the return action of the return spring 108 can make the staple plate 106 smoothly reset after a suture staple 101 is fired.

[0079] In summary, with respect to the skin stapler of the present embodiment, when the limit stopper 2 slides to a position where it does not cause a stop for the assembly bin of the outer shell, the skin seam assembly is held by hand and pushed into the assembly bin of the outer shell. After the skin seam assembly is assembled in place, the limit stopper 2 is slid again so that the limit hole 21 on the limit stopper 2 is engaged with the limit protrusion 1 on the nail bin frame, and the assembly between the skin seam assembly and the outer shell is completed. When it is necessary to disassemble the skin seam assembly from the outer shell, the limit stopper 2 is pushed by hand so that the limit hole 21 of the limit stopper 2 is disengaged from the limit protrusion 1 on the nail bin frame, and when the limit stopper 2 slides to a certain position and no longer constitutes a stop for the assembly bin of the outer shell, the skin seam assembly is held by hand and pulled out from the assembly bin of the outer shell to achieve the disassembly of the skin seam assembly from the outer shell.

[0080] Embodiment 2:

[0081] See also Figures 12 to 21 As shown, based on the skin stapler of Example 1, the skin stapler provided in this embodiment has the same general structure as the skin stapler of Example 1, the difference being that the limit stop 2 of the skin stapler of this embodiment is rotationally coupled to the front end of the outer shell of the shell assembly.

[0082] In further detail, as the limit stopper 2 rotates on the outer shell, when the limit stopper 2 rotates to a certain position, the limit stopper 2 can engage with the limit protrusion 1 on the nail magazine frame, so that the limit stopper 2 can form a stopper for the leather seam assembly to be separated from the assembly bin in the outer shell, and the leather seam assembly can be firmly assembled and limited in the assembly bin in the outer shell. When the limit stopper 2 leaves the above-mentioned engagement position with the limit protrusion 1 and rotates on the outer shell, so that the limit stopper 2 does not affect the position of the leather seam assembly to be separated from the assembly bin of the outer shell, the leather seam assembly can be smoothly separated from the outer shell, and the limit stopper 2 at this time will not interfere with the disassembly process of the leather seam assembly and the outer shell.

[0083] In an optional implementation, the outer shell of the present embodiment is matched with the limit stop 2 through the following structure, wherein mounting holes 12 are symmetrically provided at the front ends of the left shell 31 and the right shell 32, and the mounting holes 12 are located above the assembly bin of the outer shell; and rotating bosses 25 that rotate with the mounting holes 12 are respectively provided at the top ends of a pair of opposite side edges of the limit stop 2; and the rotating bosses 25 are located on the side edges of the limit stop 2 away from the limit hole 21.

[0084] It should be noted that, since the limit stopper 2 of this embodiment realizes the snap-fitting with the limit protrusion 1 after rotating to a certain position through its rotational movement, and the interference fit structure is used to ensure the tight fit between the two when the limit stopper 2 is rotated and the limit protrusion 1 is matched, and to ensure the interference fit between the two, during the rotation of the limit stopper 2, the edge of the end face of the limit hole 21 on the limit stopper 2 facing the assembly bin may interfere with the limit protrusion 1 and cause the operation resistance during the rotation of the limit stopper 2. Based on this problem, the edge of the end face of the limit hole 21 facing the assembly bin of this embodiment is provided with a guide surface 23. This guide surface 23 is designed as an arc surface, so that the design of the guide surface 23 can smoothly realize the buffering and guiding effect during the matching process of the limit hole 21 and the limit protrusion 1, so that the limit hole 21 and the limit protrusion 1 can both ensure the interference fit effect and reduce the resistance of the rotation operation.

[0085] In addition, in an optional implementation, a concave finger groove 33 is provided on the outer surfaces of the left shell 31 and the right shell 32 that are separated from each other and located on both sides of the limit stopper 2. The significance of designing the finger groove 33 in this embodiment is that when the limit stopper 2 needs to be separated from the limit protrusion 1, the limit stopper 2 needs to be pulled by the finger. Considering that it is convenient for the finger to quickly grab the limit stopper 2, the finger groove 33 is designed in this embodiment, that is, the finger only needs to pass through the position of the finger groove 33 to quickly grab the limit stopper 2.

[0086] Since the skin seam assembly of this embodiment needs to be gradually assembled into the assembly bin of the outer shell under the action of the hand holding the nail magazine frame, in order to increase the resistance between the hand and the nail magazine frame and prevent slipping, this embodiment adds anti-slip grooves 88 on the outer surfaces of the left nail magazine 81 and the right nail magazine 82.

[0087] For the skin stapler of this embodiment, compared with the skin stapler of embodiment 1, the handle 4 of the skin stapler of this embodiment does not need to be provided with a clearance groove 42, because the assembly with the skin seam assembly is achieved by the rotation of the limit block 2 in this embodiment, and in this case, it is no longer necessary to use the space of the clearance groove 42 on the handle 4 to avoid the interference of the limit protrusion 1 with the limit block 2, so the handle 4 in this embodiment does not need to be provided with a clearance groove 42. In addition, it should be noted that for the skin stapler of this embodiment, the buckle limit groove 105 can be provided on the right shell 32, or the buckle limit groove 105 can be not provided on the right shell 32.

[0088] In summary, with respect to the skin stapler of the present embodiment, when the limit stopper 2 is rotated to a position where it does not cause a stop for the assembly bin of the outer shell, the skin seam assembly is held by hand and pushed into the assembly bin of the outer shell. After the skin seam assembly is assembled in place, the limit stopper 2 is rotated again so that the limit hole 21 on the limit stopper 2 is engaged with the limit protrusion 1 on the nail bin frame, and the assembly between the skin seam assembly and the outer shell is completed. When it is necessary to disassemble the skin seam assembly from the outer shell, the limit stopper 2 is pulled by hand so that the limit hole 21 of the limit stopper 2 is disengaged from the limit protrusion 1 on the nail bin frame, and when the limit stopper 2 is rotated to a certain position and no longer constitutes a stop for the assembly bin of the outer shell, the skin seam assembly is held by hand and pulled out from the assembly bin of the outer shell to achieve the disassembly between the skin seam assembly and the outer shell.
