Abstract

A water jet arthroscope, comprising a pump body assembly (1), a water jet assembly (2), an endoscope module (3), and a cryoablation assembly (4). The water jet assembly (2) is connected to the pump body assembly (1); the endoscope module (3) is connected to the water jet assembly (2); the cryoablation assembly (4) comprises a cryo-switch ball valve (41), a cryoablation catheter (42), and a cryo-balloon (43); the cryo-switch ball valve (41) is provided on the water jet assembly (2); one end of the cryoablation catheter (42) is connected to an outlet of the cryo-switch ball valve (41), and the other end thereof passes through the endoscope module (3; the cryo-balloon (43) is provided at the other end of the cryoablation catheter (42). The water jet arthroscope is easy to operate by a doctor, causes less bleeding, achieves quick postoperative recovery of a patient, shortens an operation duration, is high in treatment effectiveness, reduces severe complications such as thrombosis, and lowers the pain level of the patient; moreover, the doctor and an observer can view an image of the knee of the patient in real time by means of an external workstation and can examine the knee of the patient in detail, so that the operation safety is increased.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a water jet arthroscope. Background technique [0002] Arthroscopy technology uses high-tech imaging technology and optical fiber technology to display the internal structure of the human body, and at the same time makes tissue repair and joint function reach the best level. Now the most widely used tool in orthopedic surgery, it was originally used only to visualize intra-articular structures and is now the most important device in most surgical procedures of every substantial joint in the body. Modern arthroscopy has become one of the main means of diagnosing and treating intra-articular diseases. It has been used in knees, shoulders, elbows, wrists, ankles, hips, and intervertebral bodies, and even in non-joint parts. However, the composition of modern arthroscopy equipment and its supporting equipment is complex and expensive. During the operation, it is often ne...
