Technical Field

The present application relates to the technical field of medical devices, and in particular to a skin stapler.

Background Art

Skin staplers are used to suture skin incisions. Existing skin staplers generally consist of three major parts: a movable handle, a fixed handle, and a stapler magazine, wherein the stapler magazine is a part for storing suture staples.

When using the skin stapler, hold the end of the movable handle and the end of the fixed handle with your dominant hand, and apply force to lift the end of the movable handle. At this time, the stapler connected to the front end of the movable handle is pressed down, so that the suture staples in the stapler magazine penetrate into the patient's skin and take shape on the skin surface to complete the suture.

In order to achieve the best suturing effect, when suturing the wound, the doctor first uses tweezers with one hand to bring the two ends of the wound together, and then uses the other hand to align the center of the skin stapler with the wound to complete the suturing. This process requires the cooperation of both hands, the operation is relatively complicated, and results in low suturing efficiency.

Please refer to Figure 5. In this embodiment, the firing assembly 240 includes a support plate 241, a spring fixing seat 242, a nail pushing block 243 and a second spring 244. The support plate 241 is arranged in the installation cavity 230, the spring fixing seat 242 is connected to the second chamber body 220, and the second spring 244 is arranged between the spring fixing seat 242 and the nail pushing block 243. The side of the support plate 241 close to the nail pushing block 243 is used to set the suture nail 600.

Bending portions 2412 are provided on both sides of the support sheet 241. The bending portions 2412 are strip-shaped and consistent with the length direction of the support sheet 241. A blocking block 214 is provided inside the first chamber body 210. The blocking block 214 and the clamping block 221 respectively abut against the two ends of the bending portion 2412 to jointly limit the movement of the support sheet 241 along its own length direction.

The spring fixing seat 242 is connected to the tail of the second chamber body 220, the nail pushing block 243 is slidably set on the support plate 241, and the second spring 244 is set between the spring fixing seat 242 and the nail pushing block 243.

In this embodiment, a hook 224 is disposed at the rear end of the second housing 220 , a block 2422 is disposed on the spring fixing seat 242 , and the hook 224 is engaged with the block 2422 .

The clamping block 2422 is protruded from the top of the spring fixing seat 242 , and the clamping hook 224 is clamped with the clamping block 2422 , so that the spring fixing seat 242 and the second chamber body 220 remain relatively fixed.

In other embodiments, the spring fixing seat 242 and the second chamber body 220 may be detachably connected via buckles or bolts, or the spring fixing seat 242 and the second chamber body 220 may be integrally formed.

Please refer to Figure 6. In this embodiment, the clamping assembly 400 includes two clamping clamps 410 and a first spring 420. The two clamping clamps 410 are rotatably connected to the nail magazine 200. The first spring 420 is connected between the two clamping clamps 410. The two clamping clamps 410 clamp the wound under the action of the nail pressing piece 500.

One end of the two clamping clamps 410 is provided with a through hole, and the rivets pass through the through holes on the two clamping clamps 410 in turn and are connected to the first chamber body 210, so that the two clamping clamps 410 can rotate around the rivet as the axis; fixed columns are also provided on the opposite side walls of the two clamping clamps 410, and the two ends of the first spring 420 are sleeved on the two fixed columns, which have a tendency to make the two clamping clamps 410 move away from the rivet at one end and move away from each other. The nail pressing piece 500 can make the two clamping clamps 410 move towards each other at one end away from the rivet, thereby clamping the wound.

Please refer to Figure 7. In this embodiment, an extension portion 510 is provided on the nail pressing piece 500. A first clamping opening 511 is provided on the extension portion 510. The two opposite inner side walls of the first clamping opening 511 can simultaneously abut against the outer side walls of the two clamping jaws 410 so that the angle between the two clamping jaws 410 gradually becomes smaller.

The first clamping opening 511 is arranged at the tail end of the extension portion 510, and the first clamping opening 511 faces the two clamping jaws 410. The first clamping opening 511 is U-shaped, and the two opposite inner side walls of the first clamping opening 511 can simultaneously resist the outer side walls of the two clamping jaws 410, so that the two clamping jaws 410 move toward each other at one end away from the rivet, and the angle between the two clamping jaws 410 gradually decreases until the two clamping jaws 410 clamp the wound at one end away from the rivet.

In this embodiment, a boss 2411 is provided at the front end of the support sheet 241, and the boss 2411 extends out of the opening 211. The boss 2411 is used to support the suture nail 600; a second clamping opening 520 is provided at the bottom of the pressing nail sheet 500, and the two opposite inner side walls of the second clamping opening 520 can abut against the two sides of the suture nail 600 located on the boss 2411, so that the suture nail 600 is deformed and suture is completed at the wound.

The boss 2411 is used to carry the suture nail 600 farthest from the push nail block 243, so as to cooperate with the nail pressing piece 500 to complete the suturing operation; the second clamping opening 520 faces the boss 2411, and the second clamping opening 520 is U-shaped; when the nail pressing piece 500 moves toward the boss 2411, the two opposite inner side walls of the second clamping opening 520 press against the two sides of the suture nail 600 located on the boss 2411, so that the two sides of the suture nail 600 are bent downward and the suturing is completed at the wound.

In this embodiment, a third fixing column 222 is provided on the second housing 220 , a third spring 223 is sleeved on the third fixing column 222 , a contact portion 530 is provided on the top of the nail pressing piece 500 , and one end of the third spring 223 away from the second housing 220 contacts the contact portion 530 .

The extension direction of the third fixing column 222 is consistent with the movement direction of the nail pressing piece 500. The end of the third spring 223 away from the second magazine body 220 abuts against the abutment portion 530, so that the nail pressing piece 500 always has a tendency to move away from the boss 2411, so that the nail pressing piece 500 presses the suture nail 600 to reset after completing the suturing.

The working principle of the skin stapler provided in this embodiment is as follows: align the skin stapler with the suturing position, hold the fixed handle 100 and the movable handle 300, so that the tail of the movable handle 300 moves toward the fixed handle 100, and the head of the movable handle 300 moves toward the pressure nail piece 500, and the head of the movable handle 300 presses down the abutment portion 530 on the pressure nail piece 500, so that the pressure nail piece 500 moves toward the boss 2411. Before the pressure nail piece 500 contacts the suture nail 600 on the boss 2411, the first clamping opening 511 on the pressure nail piece 500 will force the two clamping forceps 410 to move closer to the middle, thereby closing the skin on both sides of the wound, and the pressure nail piece 500 continues to move downward and contacts the suture nail 600. The second clamping opening 520 on the pressure nail piece 500 will force the suture nail 600 to deform and complete the suturing at the wound. The effect of pre-tightening and suturing can be achieved with one hand operation, which simplifies the suturing operation and improves the suturing efficiency.

The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
