Problems solved by technology

At present, the meniscus injury is blindly punctured during the outside-in suturing operation, which has many disadvantages, such as poor puncture accuracy, and multiple punctures will damage blood vessels, nerves, and meniscus tissues, etc.
Therefore, blind puncture is increasingly unable to meet the needs of surgery

Embodiment Construction

[0011] see figure 1 , the present invention includes a positioning arm 1 and a guide tube 2, the front end of the positioning arm 1 has a circular hole or groove, and the circular hole or groove corresponds to the tip of the meniscal puncture needle 3 passing through; the base under the positioning arm 1 is a hollow structure , can be inserted into the guide tube 2; the guide tube 2 is a hollow structure, and can be inserted into the meniscus puncture needle 3.

[0012] see figure 2 During implementation, firstly, the front end of the positioning arm 1 is pressed down on the inner edge 4 of the torn meniscus, the guide tube 2 is inserted into the base below the positioning arm 1, and the meniscus suture needle 3 passes through the guide tube 2 and passes through the skin from outside the joint, The joint capsule, the anterior angle of the meniscus or the body, and the inner edge 4 of the torn meniscus accurately arrive at the front end of the positioning arm 1 with a circula...

Abstract

The invention discloses a meniscus suture positioning guider which comprises a positioning arm and a guide tube. A circular hole or groove is formed in the front end of the positioning arm and corresponds to a pointed end of a meniscus puncture needle to penetrate through the meniscus puncture needle pointed end, a base in the lower portion of the positioning arm is of a hollow structure, the guide tube can be inserted into the base, the guide tube is of a hollow structure, and the meniscus puncture needle can be inserted into the guide tube. The meniscus suture positioning guider has the advantages that the structure is simple, the guider is easy and convenient to operate, the inner edge of a meniscus torn portion is pressed downwards by the front end of the positioning arm in a meniscus injury suture operation, a meniscus suture needle can precisely penetrate through the guide tube and the inner edge of the meniscus torn portion to reach the circular hole or groove in the front end of the positioning arm, and the defects that the meniscus puncture needle is blindly penetrated and lack of precision, and blood vessels, nerves, meniscus tissue and the like are damaged due to lots of punctures are overcome. The guider shortens time for the meniscus suture operation clinically, simplifies operation steps and improves operation quality.

Description

technical field [0001] The invention relates to a positioning guide for ensuring that a meniscus puncture needle can accurately reach the inner edge of the meniscus tear in meniscus injury suture operation. Background technique [0002] Meniscus injury is a common clinical sports injury, which can lead to pain and mobility impairment. With the deepening of research on meniscus injury, its treatment methods are gradually perfected. In recent years, the principle of treatment for meniscus injuries is to suture as much as possible to avoid the occurrence and development of osteoarthritis. There are three basic approaches to arthroscopic meniscal suturing: inside-out, outside-in, and all-inside. The outside-to-inside suture technique is mostly used for the suture of the anterior horn injury of the meniscus. This suture technique requires an auxiliary incision on the skin and is suitable for barrel-handled, longitudinal, oblique, horizontal and transverse tears in the anterior a...
