Abstract

The invention relates to the technical field of medical instruments, in particular to a surgical guide in coracoclavicular ligament reconstruction and a manufacturing method thereof. The surgical guide comprises a base. The base is a thin-wall curved plate, and the thin-walled curved surface of the plate fits and covers the surface of the area from the distal clavicle to the middle. The ratio of the length of the base to the total length of the clavicle is 0.38-0.42. The base is further provided with a first channel and a second channel. The position of the first channel is the position at thebottom of the coracoids corresponding to the central axis direction of the clavicle, the ratio of the length from the second channel to the distal clavicle and the total length of the clavicle is 0.14, and the direction is inclining by 15-30 degrees from the central axis of the clavicle. The surgical guide has the advantages of being accurate in positioning, reducing damage, saving the operationtime, reducing pains of patients and the like. The surgical guide is manufactured by adopting CT scanning and 3D printing methods, which can ensure that specification and size of the surgical guide conform to a patient, avoid the defects of the traditional unsatisfactory bone tunnel establishment position, simplify the operation and reduce the time for newcomers to learn the coracoclavicular ligament reconstruction.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a surgical guide plate in coracoclavicular ligament reconstruction and a preparation method thereof. Background technique [0002] In coracoclavicular ligament reconstruction, the accurate establishment of the bone tunnel of the clavicle and coracoid process is an important link to ensure the success of the operation. The current establishment method is completed by visual inspection or an angled locator, and the location of the bone tunnel is often not ideal. Insufficient or excessive reduction of the clavicle is caused, and the "wiper effect" occurs, leading to fracture of the reconstruction material, and even iatrogenic fracture of the coracoid process. Based on the above reasons, coracoclavicular ligament reconstruction has high requirements on the operator's surgical operation skills, and the learning curve is long, requiring years of surgical experience.
