[0027] The specific usage scenario of this embodiment is as follows: The spring 330 is compressed by sliding the slider 340. Subsequently, the staple 350 is placed inside the staple cartridge 300, and the slider 340 fixes the staple 350 inside the staple cartridge 300. Then, by pushing the staple cartridge 300, the staple cartridge 300 is inserted into the inner wall at the bottom of the housing 100.
[0028] Embodiment 3: As Figure 3 , the inner wall of the punch seat 210 is elastically connected to the top inner wall of the nail shooting chamber 120 through the second spring 220. The outer wall of the nail shooting chamber 120 is fixedly installed with a cover plate 140 in cooperation. The wrench 200 is rotatably connected to the inner walls of the nail shooting chamber 120 and the cover plate 140 through a rotating shaft 230. A limiting block 250 is fixedly installed on the outer wall of the wrench 200. A clamping block 240 is rotatably connected to the inner wall of the wrench 200. A push plate 241 is provided at the front end of the clamping block 240, and the push plate 241 is used to cooperate with the inner wall of the card slot 211 to insert and control the upward sliding position of the punch seat 210 on the inner wall of the nail shooting chamber 120.
[0029] The specific usage scenario of this embodiment is as follows: By pressing the wrench 200, the wrench 200 drives the clamping block 240 to rotate around the rotating shaft 230, so that the limiting block 250 is inserted into the card slot 211 on the inner wall of the punch seat 210. During the flipping of the limiting block 250, the punch seat 210 can be driven to move upward to adjust the position, so that the punch seat 210 is lifted upward. Subsequently, due to the upward movement of the punch seat 210, the push plate 241 is disengaged from the card slot 211. Thus, under the action of the elastic potential energy of the second spring 220, the punch seat 210 is pushed to move downward rapidly and accelerate, so that the punch seat 210 drives the punch 212 to impact the top of the staple 350 downward, so that the staple 350 passes through the staple passing groove 320, and thus the staple 350 quickly sutures the skin wound.
[0030] The working principle of the present utility model is as follows: When in use, those skilled in the art compress the spring 330 by sliding the slider 340, and then place the suture staple 350 inside the staple cartridge 300, so that the slider 340 fixes the suture staple 350 inside the staple cartridge 300. Then, by pushing the staple cartridge 300, the staple cartridge 300 is inserted into the inner wall at the bottom of the housing 100. Subsequently, by holding the housing 100 by hand, the device is attached to the position of the patient's skin to be sutured, so that the staple passage groove 320 straddles the wound. Then, by pressing the wrench 200, the wrench 200 drives the latch 240 to rotate around the rotating shaft 230, so that the limiting block 250 is inserted into the card slot 211 on the inner wall of the punch seat 210. During the flipping process of the limiting block 250, the punch seat 210 can be driven to move upward to adjust the position, so that the punch seat 210 is lifted upward. Subsequently, due to the upward movement of the punch seat 210, the push plate 241 is disengaged from the card slot 211, so that the punch seat 210 is driven by the elastic potential energy of the second spring 220 to move downward rapidly with an accelerated motion, so that the punch seat 210 drives the punch 212 to impact the top of the suture staple 350 downward, so that the suture staple 350 passes through the staple passage groove 320, thereby enabling the suture staple 350 to quickly suture the skin wound.
[0031] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
