Abstract

The invention discloses a one needle and one thread menisci stitching instrument, which belongs to the field of medical instruments and comprises a sewing needle and a guiding needle, wherein the sewing needle is provided with an axial through hole which penetrates through the needle and the guide needle, the bottom surface of the groove penetrates through the side wall of the axial through hole,the upper end of the groove penetrates through the oblique incision, and the lower end of the guide needle is provided with a tapered sharp part. The radial dimension of the sharp part is smaller thanradial dimension of the axial through hole, and the oblique incision is in smooth transition with the inner wall of the axial through hole and the outer wall of the sewing needle. The stitching instrument enables the operator to quickly and accurately determine the needle insertion angle, the needle inserting point, the needle inserting path and the needle out point under the condition that the line of sight is blocked.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a one-needle-one-line meniscus stapler. Background technique [0002] When suturing the meniscus, ordinary suturers are difficult to operate, and the position of the needle is complicated, and the angle is difficult to grasp. It often happens that the operator and the needle insertion point are on both sides of the human body, and the human body will block the operator's sight. At this time, it is necessary to With the help of auxiliary tools or staff, it is easy to have errors in the position of the needle, the position of the needle, the angle of the needle, and the path of the suture, and it is necessary to quit and re-thread the needle. This not only increases the suturing time, but also brings workload to the medical staff, and brings more pain to the patient, which is not conducive to treatment. Contents of the invention [0003] The present invention aims to provide a one...
