Meniscus suturing system and lead groove structure and guiding method thereof

Abstract

The invention discloses a meniscus suture system and a lead groove structure and a guiding method.The lead groove structure comprises a first section groove, a second section groove, a third section groove, a fourth section groove, a fifth section groove and a sixth section groove which are sequentially communicated end to end, and the head end of the first section groove and the tail end of the sixth section groove are jointly connected with an initial section groove; the whole lead groove forms a closed loop, and a preset included angle is formed between every two adjacent section grooves; and the connection site of the outer groove walls of the first section groove and the sixth section groove is deviated to the upper side of the center line of the starting section groove. According to the lead groove structure, the vibrating needle can run smoothly in the lead groove, the stroke is fixed, the stability and the high efficiency of guiding are ensured, in addition, the lead groove structure is easy to produce, no additional inclined structure is arranged at the inner bottom of the section groove, the production is simpler, and the guiding effect is more stable.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a meniscus suturing system and a lead groove structure and a guide method thereof. Background technique [0002] Meniscus tear is a very common sports injury in sports. It is often caused by the uncoordinated joint activities, such as kicking the ball, hitting the foot, or tripping or tripping during running. It gets stuck between the femur and tibia, causing a tear. If there are other conditions at the same time, such as long-term labor in a squatting position, previous ligament damage, or the original disc-shaped meniscus, etc., it is more likely to cause tearing. The elderly are also prone to tearing due to the degeneration and aging of the meniscus. And these tears can be caused even without obvious trauma. [0003] Meniscus suture refers to the surgical method of fixing the torn meniscus with suture under arthroscopy, which can effectively reduce the distance betw...

AI Technical Summary

Problems solved by technology

[0005] After analysis, it can be seen that there is a problem in this prior art. When the spring needle moves forward or backward on each branch road, it may be blocked by the intersection of the segment grooves Leading to unsmooth pushing; in order to solve this problem in this technology, it is necessary to set the bottom surface of the first groove close to the second groove and the bottom surface of the fifth groove close to the sixth groove to be inclined uphill, which increases the production cost , In addition, the problem that the continued movement of the needle may be blocked at the intersection of the third and fourth slots is still not solved
