Cut bone coping saw splashproof locator

Technical Field

The utility model belongs to the field of medical equipment, specifically speaking are cut bone coping saw splashproof locator.

Background

In the orthopedic surgery, the excision of the focus of the long bone of the limb often requires the osteotomy of the long bone. The operation of osteotomy is to introduce the wire saw for osteotomy after the bone segments of the osteotomy plane of the limb bone are fully exposed. After the osteotomy is completed, the long bone of the focus is removed from the operative field.

The traditional limb long bone osteotomy adopts an orthopedic wire saw to perform osteotomy. Due to the lack of positioning and fixing devices of the fretsaw, the operation is difficult, the osteotomy plane error is often caused, the blood vessel and nerve side injury is caused, and the operation curative effect is poor. It has the following disadvantages:

1. the wire saw osteotomy completely determines an osteotomy plane manually, so that the wire saw is difficult to fix in the osteotomy process, and the osteotomy cannot be accurately performed according to the osteotomy plane set in the operation.

2. In the process of cutting bones by a wire saw, blood vessels and nerve side injury are easily caused due to the lack of necessary protective instruments.

3. When the osteotomy is completed, the wire saw is easy to fly out of the operative field and pollute the operative space due to the lack of necessary control devices.

4. The position of the fretsaw cannot be accurately mastered in the operation process of the fretsaw, and iatrogenic injuries of operation operators are easily caused.

5. The osteotomy process needs three operators, one operator operates the wire saw, one operator protects muscle and vascular nerves, and one operator limits the displacement of the wire saw.
