The embodiment of the application provides a wound stapler as shown in fig. 1 to 2. Fig. 1 is a schematic structural view of a wound stapler according to an embodiment of the present application, and fig. 2 is a schematic structural view of a needle holder of the wound stapler according to an embodiment of the present application.

As shown in fig. 1 and 2, the wound stapler provided in the embodiment of the present application includes a rail device 300, a slider 400, a suturing needle 200, and a needle holder 100. The rail device 300 includes a left rail 310 and a right rail 320, the left rail 310 being hinged to the right rail 320, the left rail 310 and the right rail 320 forming a circular ring-shaped structure. The left guide rail 310 and the right guide rail 320 are each provided with a slide groove 360, and the slide grooves 360 are arranged along the extending direction of the left guide rail 310 or the right guide rail 320. Ensuring that the chute 360 coincides with the trajectory of the left rail 310 or the right rail 320. Each chute 360 is provided with a slider 400, the slider 400 is provided with a needle holder 100, a plurality of suture needles 200 are clamped on the needle holder 100, and the radian of the suture needles 200 is consistent with that of the chute 360.

The radian of the suture needle 200 is consistent with that of the chute 360, so that the suture needle 200 can be ensured to be perpendicular to the plane of the wound when penetrating the wound, and the suture needle is vertically inserted according with clinical requirements.

In one implementation of the present embodiment, the slider 400 is in an i-shaped or T-shaped configuration.

With continued reference to fig. 1, the end of the left rail 310 away from the hinge is a first clamping end 311, the end of the right rail 320 away from the hinge is a second clamping end 321, and two sides for clamping a clinical wound are formed between the first clamping end 311 and the second clamping end 321.

Specifically, the ports of the first clamping end 311 and the second clamping end 321 are provided with rubber sleeves. Pain in the patient can be reduced during the surgical procedure.

The working principle of the wound stapler of the embodiment of the application is as follows: first, the number of suture needles 200 is selected according to the clinical wound position and the interval between the suture needles 200 is determined, and the suture needles 200 are loaded into the needle holder 100 of the right rail 320. Second, the first clamping end 311 of the left rail 310 clamps both sides of the wound with the second clamping end 321 of the right rail 320. Again, needle holder 100 slides around chute 360 of right rail 320 from top to bottom near second grip end 321, needle 200 passes through the wound from the right side of the wound, needle holder 100 of left rail 310 grips needle 200, and needle holder 100 of right rail 320 releases needle 200; from time to time, needle holder 100 of left rail 310 slides suture needle 200 from bottom to top away from the skin tissue; finally, the doctor knots the suture. The curvature of the needle 200 conforms to the curvature of the chute 360 to ensure that each time the needle 200 is advanced, it is perpendicular to the wound skin tissue. Meanwhile, the device also meets the clinical vertical needle insertion requirement. Therefore, the wound stitching instrument disclosed by the embodiment of the application can perform disposable multi-needle stitching, so that the steps of stitching operation are reduced, the stitching stability is good, the operation efficiency is improved, and the operation time is shortened.

As shown in fig. 2, the inner and outer sides of the right and

left rails

320 and 310 are inclined in the same direction. With such a structure, the first clamping end 311 and the second clamping end 321 clamp the skin tissue of the clinical wound deeper, and the clamping force is stronger. Of course, without being limited to such a structure, the upper and lower surfaces of the right and

left rails

320 and 310 may be inclined in the same direction.

As shown in fig. 1, the sliding grooves 360 are provided on the upper surfaces of the left and

right rails

310 and 320, respectively. Of course, the chute 360 may be provided on both sides of the left rail 310 and the right rail 320 without being limited to such a configuration. The sliding block 400 may be slidably connected in the sliding groove 360.

Embodiments of the present application also illustratively provide specific configurations of needle holder 100. Needle holder 100 includes an upper handle 110, a lower handle 120, an upper jaw 130, and a lower jaw 140. The upper handle 110 is fixedly connected with the lower clamp mouth 140, the lower handle 120 is fixedly connected with the upper clamp mouth 130, and the joint of the upper handle 110 and the lower clamp mouth 140 is hinged with the joint of the lower handle 120 and the upper clamp mouth 130. The opposite surfaces of the upper handle 110 and the lower handle 120 are provided with mating connectors 160. The opposite surfaces of the upper jaw 130 and the lower jaw 140 are provided with needle grooves 150, and the suture needle 200 is clamped between the needle grooves 150 of the upper jaw 130 and the needle grooves 150 of the lower jaw 140. Needle holder 100 can hold multiple suture needles 200 at one time, saving surgical time.

In one implementation of the present embodiment, the connector 160 is a locking tooth buckle. This ensures that the needle holder 100 can be locked during the surgical procedure, so that the suture needle 200 does not fall off or shift, and the structure is more stable. Of course, such a configuration is not limiting, as long as the connector can be locked, ensuring that the suture needle 200 does not fall off or shift.

In one implementation of the present embodiment needle holder 100 is removably attached to slider 400. In actual use, a physician may choose to install different types of needle holders 100 according to different clinical wounds. Specifically, needle holder 100 is connected to slider 400 by means of a bolt and nut.

Further, the plane in which needle holder 100 is located is perpendicular to chute 360, which is more convenient for the physician. Of course, the plane of needle holder 100 may be perpendicular or not, as long as the curvature of needle 200 is consistent with that of the guide slot.

In one implementation of the present embodiment, the left rail 310 and the right rail 320 are symmetrically disposed.

As shown in fig. 1, embodiments of the present application also illustratively provide a specific implementation of the rail apparatus 300.
