Description

Lefort three-section osteotome

Technical Field

The utility model relates to the field of medical appliances, in particular to a lefort three-section osteotome.

Background

In craniofacial lefortIII osteotomy, the prior osteotome has certain difficulty in chiseling the bone of the lower wall of the orbit, and a doctor frequently needs to change the direction of the osteotome when in use and is easy to cause damage to eye contents when chiseling the bone, so that the osteotome without changing the direction can be designed, and simultaneously, the tissue can be protected at the front part of the chisel and the tissue can be separated.

Disclosure of Invention

The utility model aims to provide a Lefort three-osteotome, which aims to solve the problems that the existing osteotome used at the Lefort III position in the background art cannot protect the corners of eyes and the bone inside the cheekbones needs to be chiseled with additional tools, and the operation difficulty is increased to cause larger wound to patients.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a Lefort three-section osteotome, includes handle portion 1, connecting portion 2, separation portion 3, vice sword 4, be equipped with on the handle portion 1 connecting portion 2, the connecting portion 2 tip is equipped with separation portion 3, separation portion 3 with connecting portion 2 are integrated into one piece structure, be equipped with on the bottom surface of separation portion 3 vice sword 4, vice sword connection is fixed on being close to of connecting portion 2 separation portion 3, separation portion 3 with vice sword 4 tip flushes, forms T type form, be arc shape on the separation portion 3, separation portion 3 is blunt can protect the canthus, can laminate the canthus along the lower extreme towards the cheekbone position chisel bone use, vice sword 4 is in on the one side of separation portion 3, when using separation portion 3 to chisel the cheekbone position of Lefort III, vice sword 4 can stretch to the cheekbone inside chisel bone.

The connecting part 2 is of a bending structure, the bending angle is 135 degrees, and the bending angle of the connecting part 2 is suitable for the angle between the cheekbone position and the vertical position during use, so that the osteotome can be operated better.

Compared with the prior art, the utility model has the following beneficial effects:

the connecting part of the utility model has an included angle with a bending angle of 135 degrees, the utility model is better suitable for the operation of the cheekbone bone chisel, the end part of the connecting part is provided with a blunt separating part, the separating part has a certain radian and is suitable for protecting the canthus in the operation process on the Lefort III position, one side of the separating part is provided with a pair of cutters for the bone chisel in the cheekbone, and the utility model can reduce the trauma of patients without replacing other tools.
