AI Technical Summary
During long-term use of existing needle holders, due to the poor anti-slip effect of metal materials, it is easy to cause needle removal or displacement of the needle, which causes inconvenience to operation.
An anti-slip needle holder is designed, which is equipped with a rubber strip on the clamping surface of the clamping head. The rubber strip is buried between the groove bottom and the groove shoulder of the limit groove to form a limit anti-slip effect and provides buffering and anti-slip functions in the clamping state.
Through the limiting and extrusion effect of the glue strip, the anti-slip performance of the seam needle in the needle holder is significantly improved, ensuring stable clamping and convenient operation of the seam needle, especially the anti-slip effect in the length direction of the needle is particularly obvious.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of surgical instruments and relates to an anti-slip needle holder. Background Art
[0002] The needle holder is also called a needle holding forceps, which is mainly used to clamp the suture needle for tissue suturing operations. The needle clamp of the existing needle holder has several horizontal limit grooves, which allow the suture needle to be located in the groove to ensure that the suture needle is generally maintained at a vertical position with the forceps handle. Since the suture needle and the needle holder are both made of metal, during the long-term needle holding operation and the process of the suture needle being subjected to force (especially when the force along the length of the needle is large), the needle is easily removed or shifted due to the poor anti-slip effect between the metals, causing inconvenience to the operation. Utility Model Content
[0003] The purpose of the utility model is to provide an anti-slip needle holder in view of the above-mentioned problems existing in the prior art. The technical problem to be solved by the utility model is how to optimize the anti-slip effect of the needle holder on the suture needle.
[0004] The purpose of the utility model can be achieved through the following technical solutions: an anti-slip needle holder, characterized in that it includes two halves, the halves include a gripping portion and a clamp head, the two halves are hinged at the junction of the gripping portion and the clamp head, the clamp head has a flat clamping surface, the clamping surface has transversely distributed limit grooves, the clamping surface has a buried groove vertical to the limit groove, the buried groove divides the limit groove into two, the buried groove is filled with a rubber strip, the rubber strip is higher than the bottom of the limit groove and lower than the shoulder of the limit groove.
[0005] Furthermore, the two ends of the rubber strip are respectively provided with a limiting portion, and the two ends of the buried groove are respectively provided with positioning openings adapted to the two limiting portions.
[0006] The needle holder of the present invention is different from the existing needle holder in that: a rubber strip is arranged in the middle of the clamping surface for holding the needle, and after being buried, the rubber strip is higher than the bottom of the groove and slightly lower than the shoulder of the groove. The so-called bottom of the groove and the shoulder of the groove are the lowest and highest points of the convex and concave of the limiting groove. In this way, when the suture needle is located in the area enclosed by the two limiting grooves on the two pliers heads, the suture needle squeezes the rubber strip to form a limiting and anti-skid state. At the same time, after the clamping state of the needle holder is locked, the suture needle can be clamped by the two clamping surfaces and squeezed by the rubber strip. For the suture needle, while locking and clamping, it also has a buffering and anti-skid effect, especially the rubber strip has an obvious anti-skid effect on the suture needle along the length direction of the needle.

[0010] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0011] like Figure 1 and Figure 2 The anti-slip needle holder shown includes two halves, each of which includes a gripping portion 1 and a clamp head 2. The two halves are hinged at the junction of the gripping portion 1 and the clamp head 2. The clamp head 2 has a flat clamping surface, the clamping surface has a laterally distributed limit groove 3, and the clamping surface has a buried groove 4 perpendicular to the limit groove 3. The buried groove 4 divides the limit groove 3 into two parts. The buried groove 4 is filled with a rubber strip 5, which is higher than the bottom of the limit groove 3 and lower than the shoulder of the limit groove 3.
[0012] The two ends of the rubber strip 5 are respectively provided with a limiting portion 6, and the two ends of the buried groove 4 are respectively provided with positioning openings 7 adapted to the two limiting portions 6; what needs to be concretized is: the positioning opening 7 near the front end of the pliers head 2 is a through groove that passes through the back of the pliers head 2, and the positioning opening 7 near the tail end of the lead is a transverse groove that is observed laterally from the clamping surface but does not pass through the back of the pliers head 2, and the two limiting portions 6 of the rubber strip 5 correspond to them, and the transverse groove is inclined toward the front end of the pliers head 2. The rubber strip 5 is a deformable material made of silicone, and its initial length is slightly smaller than the buried groove 4. After it is slightly stretched, it can be stuck in the buried groove 4 and the two positioning openings 7, so that it will not naturally detach from the buried groove 4.
[0013] The parts of the needle holder that are not detailed are the same as those of the existing needle holder. The present needle holder is different from the existing needle holder in that a rubber strip 5 is provided in the middle of the clamping surface for holding the needle. After being buried, the rubber strip 5 is higher than the bottom of the groove and slightly lower than the shoulder of the groove. The so-called bottom of the groove and the shoulder of the groove are the lowest and highest points of the convexity of the limiting groove 3. In this way, when the suture needle is located in the area enclosed by the two limiting grooves 3 on the two pliers heads 2, the suture needle squeezes the rubber strip 5 to form a limiting and anti-skid function. At the same time, after the clamping state of the needle holder is locked, the suture needle can be clamped by the two clamping surfaces and squeezed by the rubber strip 5. For the suture needle, while locking and clamping, it also has a buffering and anti-skid effect. In particular, the rubber strip 5 has an obvious anti-skid effect on the suture needle along the length of the needle.
[0014] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
