Description

TECHNICAL FIELD

[0001] The utility model relates to the field of protective device, specifically a protective cover and drill protection mechanism are suitable for power equipment of orthopedics operation. BACKGROUND

[0002] In modern medical technology, orthopedic surgery is a complex and delicate operation, especially in the craniocerebral operation and spinal surgery, high-speed drill as a common power equipment, plays a vital role. High-speed drill can accurately and efficiently remove bone tissue through high-speed cutting tools. However, in the actual operation process, how to effectively fix and replace the protective cover and cutter of the drill becomes a key problem, which is directly related to the safety and efficiency of the operation.

[0003] The traditional high-speed drill usually needs to be used with the protective cover and cutter. The protective cover not only protects the operation area from debris, but also protects the operator from accidental injury to some extent. The existing protective cover mounting structure generally adopts the way of alignment and rotation, that is, the protective cover needs to be accurately aligned with the socket and locked by rotating. Although this method can achieve a certain fixing effect, there are many inconveniences in actual operation.

[0004] Firstly, the operation of alignment and rotation requires the operator to have certain experience and skills, otherwise the protective cover may not be firmly locked due to inaccurate alignment or insufficient rotation force. This not only increases the preparation time of the operation, but also may cause trouble in emergency situations. Secondly, the rotating locking structure is easy to wear after multiple uses, which reduces the locking effect and increases the risk of accidental falling of the protective cover. Finally, the traditional installation method is complicated to disassemble and reinstall, increasing the maintenance difficulty.

[0005] In order to overcome these problems, some improved schemes have been proposed in the prior art. For example, the protective cover and cutter are combined together in the prior art, called drill head, and the installation structure of the drill head is improved to simplify the operation. However, this method still has some shortcomings, such as complex overall structure, high manufacturing cost, and lack of universality between different models of drill heads, which limits the use range.
