Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a human tissue shaving and collection device. Background Technology
[0002] Arthroscopy is a commonly used clinical tool for treating intra-articular lesions. Arthroscopic minimally invasive techniques are widely applied in clinical practice, often used for the removal of intra-articular lesions and the repair of damaged tissues. It offers advantages such as minimal trauma and rapid recovery. Arthroscopic lesion removal includes procedures such as resection of inflammatory synovium, osteophyte removal, removal of diseased bone and cartilage tissue, and resection of space-occupying lesions such as intra-articular tumors. The primary resection method involves using a high-speed rotating shaving or grinding tool under arthroscopy to break up the tissue, which is then aspirated from the joint through a connected negative pressure tube and collected in a negative pressure suction bottle. Clinically, the diagnosis and treatment of diseases heavily rely on the pathological analysis of the lesion tissue. This requires that the collected pathological tissue be the most typical part of the lesion, and the collection operation must be performed under aseptic conditions. To improve the efficiency of collecting the target lesion tissue, a collection device is needed. However, existing collection devices still have the following shortcomings:
[0003] When existing collection devices are used, most of them are not sterile, and the various lesions and partially excised normal tissues are mixed together, making it impossible to distinguish and classify the lesions. This results in a decrease in the practicality and efficiency of the collection devices.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a human tissue scraping and collection device. Utility Model Content
