[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1-3 As shown, a disposable nail storage box of a skin stapler includes a nail storage box assembly 1, a reset assembly 2 capable of maintaining axial rotation is arranged inside the nail storage box assembly 1, a nail outlet groove 104 is provided at the bottom of the nail storage box assembly 1, the reset assembly 2 includes a rotating shaft 201, an outer wall of the rotating shaft 201 is provided with support rods 202 distributed in a circular array to support suture nails, and an outer wall of the rotating shaft 201 at one end near the nail outlet groove 104 is connected to a clamping block 105, and the clamping block 105 maintains synchronous axial rotation with the rotating shaft 201.

[0025] The main purpose of the staple storage box of the disposable skin stapler is to support the suture staples through the support rods 202 on the outer wall of the rotating shaft 201, and when the suture staples remain tilted, the supporting rods 202 can keep the rotating shaft 201 axially rotating, and then drive the clamping block 105 to keep rotating synchronously so that the clamping slot 106 and the suture staple can maintain the same tilt angle, thereby keeping the suture staple fixed; and through the pressure rod 205 set between the fracture of the rotating shaft 201 corresponding to the staple outlet groove 104, the suture staple can be pressed down from the fracture and popped out of the staple outlet groove 104 by downward pressure, thereby performing the suturing work.

[0026] In the technical solution provided by this utility, Figure 1 , Figure 2 and Figure 3 It can be seen that the nail storage box assembly 1 includes a nail storage box 101, and a nail storage groove 102 is also opened inside the nail storage box 101 for placing suture staples, and a push block 103 is slidably arranged inside the nail storage groove 102 to squeeze the suture staples, so that the suture staples remain in a fixed state.

[0027] Furthermore, the outer walls of the block 105 and the push block 103 on both sides are provided with a slot 106, and the slot 106 inside the block 105 extends outward to communicate with the nail outlet slot 104, so that the suture nail can be ejected from the nail outlet slot 104 when the downward pressure is applied to perform the suturing work.

[0028] Furthermore, the position of the rotating shaft 201 corresponding to the nail outlet groove 104 remains disconnected, and a pressure rod 205 is provided at the disconnected portion of the rotating shaft 201. The pressure rod 205 can only rotate in the direction of the nail outlet groove 104, so that the disconnected portion remains connected to the nail outlet groove 104, so that the suture nail is pressed down and popped out from the disconnected portion to perform the suturing work.

[0029] Furthermore, a connecting rod 204 is connected between the rotating shaft 201 and the clamping block 105, and the connecting rod 204 can drive the clamping block 105 and the rotating shaft 201 to maintain synchronous axial rotation, so that the clamping slot 106 opened by the clamping block 105 can be consistent with the angle between the suture staple and the staple storage box 101, so that it can be clamped into the inside of the clamping slot 106, and then the clamping block 105 can be squeezed by pressing down and closing the staple storage box 101, so that it can be reset as the rotating shaft 201 rotates, driving the suture staple to be clamped into the inside of the staple storage slot 102.

[0030] Furthermore, a rotating wheel 203 is provided at the end of each support rod 202 away from the rotating shaft 201, and each support rod 202 is kept extending to the inner wall close to the nail storage groove 102, so the length of the support rod 202 away from the nail outlet groove 104 is shorter than the length of the support rod 202 close to the nail outlet groove 104.

[0031] Working principle: by placing the suture staples inside the staple storage box 101, when the suture staples are tilted and stuck in the staple storage box 101, the support rod 202 can be squeezed, thereby driving the rotating shaft 201 to rotate axially, thereby driving the clamping block 105 to rotate axially, so that the angle between the clamping slot 106 inside the clamping block 105 and the suture staples and the staple storage box 101 is consistent;

[0032] Then, the push block 103 is pushed and squeezed to make the suture staples clamped in the clamping groove 106, and then the staple storage box 101 is closed and pressed down, thereby driving the clamping block 105 to rotate and reset, so that the suture staples clamped inside are completely clamped in the inside of the staple storage box 101;

[0033] Then, by applying downward pressure, the suture nail is ejected from the disconnected portion of the rotating shaft 201 and out of the nail groove 104, and the suture work is performed.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
