Telescopic 3D printed osteotomy guide plate with dual-locking structure

Abstract

The invention discloses a telescopic 3D printed osteotomy guide plate with a dual-locking structure. The guide plate comprises a left plate body and a right plate body which are integrally shaped by 3D printing, and a telescopic structure which can realize relative expansion and contraction of the left plate body and the right plate body. Through use of the osteotomy guide plate disclosed by the application, on one side, all components are integrally shaped by 3D printing, the components are mutually limited or nested, relative motion among the components is satisfied, mutual stripping among the components is avoided, and safety and convenience in an operation are improved; and on the other side, the guide plate has a function of adjusting expansion and contraction and the guide plate canhas a small volume while being put into an incision, and the guide plate is adjusted to a large volume after being put into the incision, so that flexibly and convenience in the operation are greatlyimproved. After volume deformation, the guide plate can be stabilized in a working state, thus the volume and shape of the guide plate are not influenced by maxillofacial surface muscle traction, positioning accuracy is ensured, and the dual-locking structure can prevent unlocking caused by a misoperation.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a telescopic 3D printing osteotomy guide plate with a double locking structure. Background technique [0002] With the development and progress of modern social civilization, people pay more attention to their appearance and body shape while pursuing a higher quality of life. The mandible is an important component structure for constructing facial contours, thus becoming a key part of plastic and cosmetic surgery. Asian women often use the "oval face" as one of the specific expressions of aesthetics. On the contrary, hypertrophy of the mandibular angle makes the face look too round and lacks the gentle beauty of oriental women. The mandibular angle resection can remove the hypertrophic bone in the mandibular angle area, coordinate the proportion of the lower 1 / 3, and improve the facial shape. Therefore, it is favored by the majority of beauty lovers and has become the most used su...

Problems solved by technology

Surgery is often performed with a small incision in the oral cavity. Although the traditional personalized guide plate can improve the accuracy of the operation, it is difficult to put it into the incision due to its large size and non-stretchable reasons, and it is prone to deviation in position.

[0008] 2. Although some people propose to use a jigsaw puzzle-like structure to print the guide plate in pieces, due to the rich muscle tissue around the jaw, the guide plate is prone to relative displacement between each puzzle piece due to the lack of in-position constraints during the placement process, making positioning Accuracy drops

[0009] 3. In the traditional surgical procedure without using a guide plate, the positioning depends entirely on the experience of the surgeon, and there is a lot of subjectivity
