Under the condition, when the skin seam component is assembled in the assembly bin of the outer shell, the skin seam component is partially embedded into the abdicating groove 42 of the handle 4 through the nail bin frame body, so that the limiting convex block 1 moves towards the handle 4 along with the nail bin frame body synchronously, and the limiting stop block 2 can smoothly slide to a position suitable for being clamped with the limiting convex block 1, and after the limiting stop block 2 slides to the position, the limiting convex block 1 moves towards the front end of the skin stitching instrument through the skin seam component, so that the limiting convex block 1 is just clamped into the limiting hole 21 of the limiting stop block 2.

In the above process, under the condition that the skin suture assembly moves to the 'rear end' of the skin suture instrument for a certain distance to avoid the interference of the protruding height of the limit bump 1 to the movement process of the limit stop 2, after the limit stop 2 slides to the position suitable for being clamped with the limit bump 1, the acting force of the skin suture assembly moving to the 'front end' of the skin suture instrument is applied, the skin suture instrument adopted by the embodiment does not need to additionally design a special driving structure for enabling the skin suture assembly to move to the 'front end' of the skin suture instrument, but is directly realized by the pushing spring 104 of the nail structure. The specific principle is as follows: in the process of assembling the skin suture assembly into the outer shell, when the spring buckle 103 of the nail feeding structure is clamped with the buckle limiting groove 105 of the outer shell, the nail bin frame body does not enter the abdicating groove 42 on the handle 4 at the moment, and the limiting bump 1 can cause the interference of the sliding of the limiting stopper 2, so that the skin suture assembly is required to be pushed to the back end of the skin suture instrument continuously by applying acting force to the skin suture assembly through hands, so that the limiting bump 1 forms the abdicating effect on the limiting stopper 2 along with the pushing process of the nail bin frame body, in the process, as the spring buckle 103 is clamped by the buckle limiting groove 105 of the outer shell, the spring buckle 103 can not be pushed to the back end of the skin suture instrument synchronously along with the nail bin frame body, thus limiting the axial end of the pushing spring 104 to make the pushing spring 104 incapable of moving, in this case, the suturing nail 101 and the nail pushing plate 102 can still move synchronously along with the nail bin frame body, in the moving process, the pushing spring 104 is compressed under the action of the nail pushing plate 102, and along with the further movement of the nail bin frame body, when the nail bin frame body is partially embedded into the abdicating groove 42, the limiting bump 1 does not interfere with the sliding of the limiting stop block 2 any more; when the limit stop 2 slides to a position suitable for being clamped with the limit bump 1, at the moment, the nail bin frame body can utilize the reset acting force of the pushing spring 104 to enable the skin suture assembly to be pushed towards the front end of the skin suture device, so that the limit bump 1 just enters the limit hole 21 of the limit stop 2, and clamping matching between the limit stop 2 and the limit bump is achieved. In summary, in this embodiment, the spring buckle 103 of the nail structure is matched with the buckle limiting groove 105 of the outer housing to realize the acting force of the skin suture assembly in the pushing process to the front end of the skin suture device, so as to avoid the problem of additionally adding a driving structure, and simplify the structure of the whole skin suture device.

It should be noted that, in the process of pushing the skin suture assembly to the "rear end" of the skin suture instrument, when the end of the spring buckle 103 departing from the buckle limiting groove 105 just abuts against the alignment assembly structure formed by the insertion and matching of the alignment post 86 and the alignment hole 87, the skin suture assembly cannot be pushed to the "rear end" of the skin suture instrument, and at this time, the limiting protrusion 1 no longer constitutes the interference of the sliding of the limiting stopper 2, that is, in the process of pushing the skin suture assembly to the "rear end" of the skin suture instrument by the force applied by the hand, when the skin suture assembly cannot be pushed to the "rear end" of the skin suture instrument, the skin suture assembly is pushed to the right position, and in such a structure, it is not necessary to add an additional structure for grasping the pushing progress of the skin suture assembly to the "rear end" of the skin suture instrument, and the skin suture assembly can be known by the hand feeling, the skin stitching instrument has the advantages that the structure of the skin stitching instrument is simplified, and the convenience in operation is improved. The specific implementation mode of the structure only needs to design that the height of the limiting lug 1 relative to the protrusion of the nail bin frame body is equal to or slightly smaller than the distance between the end part of the spring buckle 103 departing from the buckle limiting groove 105 and the alignment assembly structure in the clamping state of the limiting lug 1 and the limiting stop block 2.

Finally, it should be further noted that the skin stapler of the present embodiment further includes a staple forming plate 106 of a skin stapler mature in the prior art and adapted to cooperate with the handle 4, the staple forming plate 106 is adapted to eject the staples 101, so that the staples 101 can be fired under the action of the handle 4 and the staple forming plate 106; and the staple forming plate 106 is also matched with a return spring 108, one end of the return spring 108 is abutted against the staple forming plate 106, while the other end is abutted against the staple box frame body, in the process of firing the staples 101 by the staple forming plate 106, the return spring 108 is compressed and deformed, and the return action of the return spring 108 can enable the staple forming plate 106 to be smoothly reset after one staple 101 is fired.

To sum up, as for the skin stitching instrument of this embodiment, when limit stop 2 slides to the backstop that can not cause the assembly storehouse to the shell body, the hand grips the skin seam subassembly, in advancing the assembly storehouse of packing into the shell body with the skin seam subassembly, treat the skin seam subassembly and assemble the position back, slide limit stop 2 again for spacing hole 21 on limit stop 2 and the 1 joint of spacing lug on the nail storehouse support body, the assembly between skin seam subassembly and the shell body has been accomplished this moment. When the skin seam subassembly is dismantled from the shell body as required, as long as promote limit stop 2 with the hand for limit stop 2's spacing hole 21 breaks away from with spacing lug 1 on the nail storehouse support body, when limit stop 2 slides to a certain position and no longer constitutes the backstop to the assembly storehouse of shell body, the rethread hand grips the skin seam subassembly this moment, pulls out the skin seam subassembly from the assembly storehouse of shell body and can realize the dismantlement between skin seam subassembly and the shell body.

Example 2:

referring to fig. 12 to 21, on the basis of the skin suturing device of embodiment 1, the skin suturing device of the present embodiment has the same general structure as the skin suturing device of embodiment 1, except that the limit stop 2 of the skin suturing device of the present embodiment is rotatably coupled to the front end of the outer housing of the housing assembly.

In further detail, along with the rotation of limit stop 2 on the shell body, when limit stop 2 rotated to a certain position, limit stop 2 can be in joint with limit lug 1 on the nail bin support body, thereby enabling limit stop 2 to form the stopping function of detachment of the skin seam assembly from the assembly bin in the shell body, and enabling the skin seam assembly to be firmly assembled and limited in the assembly bin in the shell body.
