Meniscus stitching instrument and positioning tube thereof

Abstract

The invention provides a meniscus stitching instrument and a positioning tube thereof. Wherein the positioning pipe comprises a first straight pipe, an arc-shaped pipe and a second straight pipe, the front end of the first straight pipe is connected with the left end of the arc-shaped pipe, the interior of the first straight pipe is communicated with the interior of the arc-shaped pipe, the second straight pipe is fixedly connected with the first straight pipe, and the extension line direction of the front end of the second straight pipe is aligned with the right end of the arc-shaped pipe; the interior of the second straight pipe is used for allowing the puncture pipe to penetrate through and guiding the puncture pipe, and the right end of the arc-shaped pipe is used for allowing the puncture pipe to be inserted. Due to the fact that the extension line of the front end of the second straight pipe is aligned with the right end of the arc-shaped pipe, the puncture pipe can quickly and effectively penetrate through the second straight pipe under the guidance of the second straight pipe and is connected with the right end of the arc-shaped pipe in an inserted mode, and then a working channel for puncture of a puncture needle is formed in the first straight pipe, the arc-shaped pipe and the positioning pipe. Therefore, the positioning tube can be used for positioning the puncture tube for meniscus suture, 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 of the lateral meniscus and body damage, disposable meniscal suturers are used at home and abroad, which are produced by foreign countries and whose patents are held abroad. The disposable meniscal suturing device mainly has the following disadvantages: (1) high cost: the suturing device is a disposable consumable, and the price is about 5,000 yuan each, while 2 to 3 pieces are needed to suture the outer side each time, and the cost is 10,000-15,000 yuan (2) When the stapler is applied blindly to the back of the knee joint, there is a possibility of injuring the posterior popliteal artery, popliteal vein, and common peroneal nerve. According to literature records, this possibility can reach 5%; (3) Technical The patent is abroad, and ...
