Abstract

The invention provides a special holding forceps for maxillary Le Fort I osteotomy, belonging to the technical field of clinical medicine; the special holding forceps for maxillary Le Fort I osteotomy is composed of an upper forceps body, a lower forceps body and a personalized plate ;The upper clamp body and the lower clamp body are crossed and connected through the pin shaft, and the height can be adjusted up and down. The lower adjustable clamp and the lower bow-shaped clamp beak are connected by concave screws, and the width can be adjusted by opening and closing left and right. The personalized board is inserted and connected by the side concave structure and the lower side protruding structure which can be adjusted and clamped. In intraoperative use, when the maxillary bone segment is broken, the front end of the upper forceps body is used to clamp the nasal base bone tissue, and the lower adjustable forceps are adjusted to suit different arch widths, and then the maxillary dentition is accurately contacted. The upper and lower clamp handles loosen and retract the maxillary segment. The special holding forceps for osteotomy of the present invention protects the soft tissue and mucosa of the hard palate, thereby reducing intraoperative damage, and realizing precise and stable clamping of the maxillary segment.

Description

technical field [0001] The invention belongs to the technical field of clinical medicine, and in particular relates to a special holding forceps for maxillary Le Fort I osteotomy and a method for using the same. Background technique [0002] Maxillary Le Fort I osteotomy is one of the most commonly used surgical procedures in orthognathic surgery. Its function is to correct the deformity of the maxilla in multiple spatial directions such as vertical, horizontal, and anterior and posterior directions. A prerequisite for successful surgery is the complete release of the maxillary segment after fracture. However, in the current operation, it is necessary to directly contact the mucosa of the maxillary hard palate through the special holding forceps for the maxilla to complete the release process. In the process of use, if the grip is too strong, it will cause contusion or other damage to the soft tissue and mucous membrane of the hard palate to a certain extent; None of the a...
