Meniscus stapler and its positioning tube

Abstract

The present invention provides a half -moon plate suture and its positioning tube.Among them, the positioning tube includes the first straight tube, the arc tube, and the second direct tube.The tube is fixed with the first straight tube, and the front -end extension line of the second direct pipe is aimed at the right end of the arc -shaped tube.The right end is used for puncture tube insertion.Because the front -end extension of the second direct tube is aimed at the right end of the curved tube, so that the puncture tube can quickly and effectively pass through the second direct tube and insert it with the right end of the arc tube under the guidance of the second direct tube.Together, the internal channels for the first direct tube and the arc tube are formed for piercing needle and puncture.Therefore, the positioning tube of the present invention can locate the puncture tube of the semi -moon plate, and the positioning operation is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a meniscus stapler and a positioning tube thereof. Background technique [0002] At present, for the suture repair of the posterior horn and body of the lateral meniscus, disposable meniscus sutures are used at home and abroad, produced for foreign countries, and the patents are held abroad. The disposable meniscus suture mainly has the following disadvantages: (1) High cost: the suture is a disposable consumable, and the price of each is about 5,000 yuan, while the outer side of the suture needs to be used 2 to 3 each time, and the cost is 10,000-15,000 yuan (2) Blindly puncture the posterior side of the knee joint when the stapler is applied, there is a possibility of injuring the posterior popliteal artery, popliteal vein, and common peroneal nerve. According to literature, this possibility can reach 5%; (3) Technical The patent is abroad, and the supply may be affe...
