intra-articular release device

Abstract

The invention discloses an intra-articular loosening device, which belongs to the field of medical devices, and is used to solve the problem that in the prior art, the acupotomy mirror can only peel off the diseased tissue, and after the peeling, the acupotomy mirror needs to be pulled out to use other surgical tools again. After the peeled lesion tissue is removed, it is a blind operation during the removal process, which is inconvenient to operate. It includes a light guide core, a light guide tube, and a knife tube. The light guide tube is sleeved outside the light guide core, and the knife tube is sleeved outside the light guide tube. flush, the lower end of the knife tube is connected with a blade; the knife tube is also covered with a sheath tube, and the side wall of the lower end of the sheath tube is axially provided with two symmetrical slide grooves, and the two sides of the blade are The edges are embedded in the chute; the lower ends of the two symmetrical chutes are provided with incisors, one end of the incisors is connected to the chute through a pin shaft, a linkage mechanism is provided between the incisors and the blade, and the incisors are downward One end opens and closes with the axial relative movement of the blade and the chute through the linkage mechanism. Under the scheme of visual stripping of diseased tissue, the technical solution integrates visual clamping and removal of diseased tissue, which is convenient for operation.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to an intra-articular release device. Background technique [0002] Ordinary arthroscopic treatment usually requires 3 or more channels to be opened at the surgical site to facilitate operation. During the treatment process, the damaged mucosa, cartilage and other tissues are mainly cut off or exploited, which are relatively large and the recovery time is relatively long; [0003] The minimally invasive needle-knife mirror has an incision of less than 0.5 cm during treatment, and at most two channels can be opened. Sometimes one channel can also complete the entire diagnosis and treatment process. Relieve adhesions, eliminate inflammation, restore function, and the intraoperative trauma is relatively small. [0004] For example, the patent document with application number CN201110458403.7 discloses a minimally invasive integrated needle-knife mirror, including a mirror-knife combined...

AI Technical Summary

Problems solved by technology

[0005] However, in the prior art, the acupotomy mirror can only peel off the diseased tissue. After the peeling, it is necessary to pull out the needle knife mirror and use other surgical tools to remove the peeled diseased tissue. During the removal process, it is a blind operation, which is inconvenient to operate.
