Description

Bone cutting forceps

Technical Field

The utility model relates to the technical field of medical equipment, more specifically the utility model relates to an osteotomy forceps that says so.

Background

In hospital orthopedics, often meet some diseases and need carry out the osteotomy operation, need use the osteotomy pincers to fix the bone centre gripping in the osteotomy operation, then cut the bone with the line data, be about to the line data encircle the skeleton after, medical personnel's both ends that the line data was carried to both hands move back and forth from top to bottom, thereby make the line data carry out cutting motion to the skeleton and realize the osteotomy operation.

However, in the actual operation process, the line data is not guided, so that the line data can deviate from cutting in the cutting process, and the bone cutting effect is greatly reduced; moreover, because no protective measures are set, the suture thread is in direct contact with soft tissues around the skeleton, so that cutting damage can be caused to the soft tissues around the skeleton in the process of cutting the suture thread, further the influence of increased bleeding, limited postoperative functions and the like is caused, and the operation risk is improved; in addition, because the osteotomy forceps do not have a self-locking function, the osteotomy forceps need to use external force to clamp bones all the time, and the medical staff is easy to feel fatigue.

Therefore, how to provide an osteotomy forceps which can cut and guide the wire to improve the osteotomy effect and reduce the cutting damage to soft tissues around the bone during the cutting of the wire to reduce the operation risk, has a self-locking function, does not need the medical staff to clamp the bone by using external force all the time and reduces the physical labor of the medical staff is a problem to be solved urgently by the technical staff in the field.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a can have cutting guide effect to the line according to improve the osteotomy effect, and the cutting damage to soft tissue around the skeleton when reducible line is according to the cutting, with reduce the operation risk, and the osteotomy pincers have self-locking function, need not medical personnel and use external force pincers to hold the skeleton always, with the osteotomy pincers that alleviate medical personnel's manual labor.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

an osteotomy forceps comprising:

the wire drawing mechanism comprises a first clamp handle and a second clamp handle which are arranged in a mutually crossed manner, wherein the first clamp handle and the second clamp handle are movably connected through a hinged shaft;
