Meniscus suture guider

Abstract

The invention relates to a meniscus suture guider. The meniscus suture guider comprises a guiding device and a positioning rod; a needle hole, a side edge groove and an inserting groove are formed in the guiding device, and the needle hole extends from the first side face of the guiding device to the middle and extends to be communicated with the needle hole; the inserting groove penetrates through the guide device from the top surface to the bottom surface of the guide device; the positioning rod comprises a positioning rod head and a positioning rod part, the positioning rod part can be inserted into the inserting groove in a sliding mode, a fixing screw is arranged on the second side face of the guiding device, the fixing screw is inserted into the inserting groove from the second side face, and therefore when the guiding device is adjusted to a proper position, the positioning rod part is fixed into the inserting groove by screwing down the fixing screw; the positioning rod head comprises a puncture hole and an arc-shaped part, and the puncture hole is formed in one end of the arc-shaped part; the other end of the arc-shaped part is fixedly arranged at the top end of the positioning rod part, and when the positioning rod part is fixed in the inserting groove through the fixing screw, the needle hole corresponds to the puncture hole in position.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a meniscus suture guide. Background technique [0002] The suture of the anterior horn of the meniscus needs to be sutured from the outside-in method. Clinically, the puncture needle with a coil method is used to perform blind puncture from the outside through the skin to the inside of the joint. The operation depends on the surgeon's sense of spatial positioning, so It is difficult to complete in one step, especially for beginners. [0003] In the prior art, the suturing of the anterior corner of the meniscus adopts the method of blind piercing with a puncture needle and a coil, which relies on the operator's experience and sense of spatial positioning, and there is no special guiding and positioning tool. The operator uses the puncture needle to estimate the anatomical position for positioning and puncture, which is not accurate and requires repeated attempts. [0004...

Problems solved by technology

The operator uses the puncture needle to estimate the anatomical position for positioning and puncture, which is not accurate and requires repeated attempts

[0004]Because the existing technology relies on the operator’s feeling, it needs to accumulate experience, and it needs to be corrected by trial and error, which is inefficient and the head of the ACL locator does not match. It is difficult to fix the meniscus, the guide device is long, and the length of the needle is not enough, which increases the difficulty of the operation
