Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a medical bone scraper. Background Technology

[0002] A bone curette is a manual medical tool commonly used to treat orthopedic diseases and perform related surgical procedures. It utilizes its special shape and material, along with the surgeon's hand strength, to scrape away bone structures or soft tissue to achieve therapeutic goals. Existing technologies use curettes with various shapes and structures, and the ends of the curettes are prone to wear, leading to their direct scrapping and waste. To address this, Chinese invention patent CN108852460A discloses an orthopedic curette with a hollow tubular handle. An end cap is fitted to the right side of the handle and is threaded onto the handle. A serrated spoon, elliptical in shape with serrated edges, is placed inside the handle. A spring post is attached to the left side of the handle, and a connecting rod is attached to the left side of the spring post. The curette is threaded to the front end, allowing for curette replacement. However, it has the following drawbacks:

[0003] When using a scraper connected by a thread, the force generated between the scraper and the contact area can easily cause the scraper to rotate, leading to loosening of the threaded connection and causing the scraper to come off the handle, which is not conducive to its use.
