Mandibular osteotomy guide plate capable of retaining apodeum and production method thereof

Abstract

The invention discloses a mandibular osteotomy guide plate capable of retaining apodeum. The mandibular osteotomy guide plate is characterized by comprising two osteotomy guide plates and a connecting rod for connecting the two osteotomy guide plates, wherein the two osteotomy guide plates are provided with osteotomy guide wire grooves; and both the osteotomy guide plates are provided with fixing holes. A patient is subjected to maxillofacial CT before an operation, and CT data are imported into digital surgical auxiliary software in a DICOM format; the mandible is separated in the software, and simulation design of the osteotomy guide plate and bone flap repair are carried out; and after 3D printing is carried out on a repaired model, titanium plate bending and nail hole presetting are carried out on the basis, and CT is carried out on the model again. After osteotomy repair simulation, the mandible model, a titanium plate and nail hole model are subjected to fitting to complete nail road transfer; related data is imported into three-dimensional design software in a stl file format; design of the osteotomy guide plate is carried out; and after design is completed, 3D printing is carried out. The mandibular osteotomy guide plate is simple to operate and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a mandibular osteotomy guide plate capable of retaining muscle attachment and a manufacturing method thereof. Background technique [0002] The mandible is located in the protruding part of the maxillofacial region and is the only movable bone in the human head and face, which plays a decisive role in the shape and function of the human face. For some benign and malignant tumors and cystic lesions of the mandible, partial mandibular resection (osteotomy) is a common treatment method, which aims to completely and precisely remove the tumor while protecting the surrounding healthy tissue as much as possible. [0003] For the conventional partial mandibular resection, traditionally, the surgeon mainly uses a wire saw or a power saw to perform osteotomy according to personal experience and preoperative imaging examination results. [0004] Most of the current mandibular os...

Problems solved by technology

Such a design often leads to a huge volume of the guide plate, which makes it difficult to place it in place, and requires a large area of ​​peeling off the surrounding muscle tissue to be placed in place

However, in a large amount of clinical work, we found that the stripping of the masticatory muscles (masserus, temporalis, medial pterygoid, lateral pterygoid) during surgery often leads to damage to the postoperative mastication and mouth opening and closing functions of patients, while the suprahyoid Excessive stripping of muscle groups often leads to postoperative tongue retraction to block the airway, endangering the life of the patient
