Description

A toothed tweezers for surgery

technical field

The utility model belongs to a surgical instrument, in particular to a toothed tweezers for surgical operations.

Background technique

Toothed tweezers (skin tweezers) are indispensable medical instruments for surgical operations, and are used when suturing various tissues including muscle, subcutaneous tissue and skin. According to the inventor's many years of surgical experience and understanding, the current toothed tweezers are not perfect in design, and one of the main defects is that it is not easy to clamp the suture needle after the needle is pulled out when suturing the tissue. The reason is that the inner surface of the toothed tweezers head end is Smooth. Owing to can not clamp suturing needle, this brings many troubles to suturing, is unfavorable for the smooth carrying out of operation.

Contents of the invention

Aiming at the shortcomings of the existing surgical forceps, the purpose of this utility model is to provide a toothed forceps capable of fixing suture needles, which can effectively clamp the suture needles, so that the surgical suture work can be carried out smoothly.

In order to realize above-mentioned technical task, the utility model adopts following technical scheme:

A kind of toothed tweezers for surgery, including tweezers handle, tweezers arm and tweezers head, the tweezers head includes an upper tweezers head and a lower tweezers head, the upper tweezers head adopts a trapezoidal platform, on the top of the trapezoidal platform The surface is provided with teeth, and the lower tweezers head is provided with an alveolar that cooperates with the upper teeth of the upper tweezers head. When the tweezers are clamped, the upper tweezers head and the lower tweezers head can be tightly occluded; one side of the alveolar Needle grooves are provided on the tweezers arm along the axial direction of the tweezers arm, and convex lines are arranged in the needle grooves.

The ends of the teeth of the upper tweezers are plane.

The utility model improves the structure of the existing toothed tweezers, adds occlusal teeth, adds needle grooves, and provides anti-slip convex lines in the needle grooves, so that the surgical tweezers can closely and effectively carry out suturing needles of different diameters. Effective clamping, so that the suture needle will not slip or fall off. The utility model has the advantages of simple structure, practical function and low cost, and provides a good auxiliary tool for the smooth operation of surgery.

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

Detailed ways

Provide the specific embodiment of the utility model below, it should be noted that the utility model is not limited to the following specific embodiments, and all equivalent transformations done on the basis of the utility model technical solution are all within the protection scope of the utility model.

Example:

According to the above-mentioned technical scheme, as shown in Fig. 1 to Fig. 3, a kind of toothed tweezers for surgical operation includes tweezers handle 1, tweezers arm 2 and tweezers head, and the tweezers head includes an upper tweezers head 3 and a lower tweezers head Head 4, the upper tweezers head 3 adopts a trapezoidal platform, and the top surface of the trapezoidal platform is provided with teeth 301, and the lower tweezers head 4 is provided with an alveolar 401 that cooperates with the upper teeth 301 of the upper tweezers head 3 , when the tweezers are clamped, the upper tweezers head 3 and the lower tweezers head 4 can tightly bite; the tweezers arm 2 on the side of the tooth groove 401 is provided with a needle groove 402 along the axial direction of the tweezers arm 2, and in the needle groove 402 Ribs 403 are provided.

In the present embodiment, the upper tweezers head 3 is an inverted trapezoidal platform, as shown in Figure 2, the bottom surface of the trapezoidal platform is consolidated on the tweezers arm 2; the top surface of the trapezoidal platform has teeth 301, and the quantity of the teeth 301 can be determined according to the actual situation. It needs to be set up, because the needle body of the suture needle is relatively smooth, so in order to effectively clamp the suture needle, the teeth 301 do not use sharp teeth, but are processed into a plane 302 at the top of the teeth 301, correspondingly, the lower tweezers The slots 401 of the head 4 are provided with slots 401 corresponding to the structure of the teeth 301, so that the upper tweezers head 3 and the lower tweezers head 4 are in a tightly closed state when the tweezers are clamped.

As shown in Figure 3, on the side of the alveolar 401 of the lower tweezers head 4, a needle groove 402 is provided along the axial direction of the tweezers arm 2, and the diameter of the needle groove 402 is set according to the outer diameter of the suture needle, so that the needle tail of the suture needle Can be embedded in the needle groove 402; the length of the needle groove 402 is different, and can be opened according to the specifications of different suture needles. When the tweezers clamp the suture needle, the needle tail is embedded in the needle groove 402 and stands against the end of the needle groove 402; The body is clamped by the upper tweezers head 3 and the lower tweezers head 4, so that the suture needle can be clamped in all directions so that it cannot slide or move. Depending on the position of the suture needle to be clamped, different needle slots 402 are selected for clamping.

A raised pattern 403 is arranged in the needle groove 402 , and the raised pattern 403 can be arranged along the direction of the needle groove 402 or perpendicular to the direction of the needle groove 402 so that the suture needle cannot slide in the needle groove 402 .
