Problems solved by technology

Minimally invasive surgery requires the use of locators for bone tunnel positioning and establishment. At present, cruciate ligament reconstruction locators are basically used, which is a flat locator and non-stereoscopic. Due to the anatomical position of the coracoid process and the clavicle, the coracoid process and the clavicle are in The position is not on a plane, but in a three-dimensional cross direction. When using the cruciate ligament reconstruction locator, it will be partially blocked, making it difficult to locate smoothly and affecting the accuracy of positioning.

Abstract

The invention provides a positioning device. The positioning device comprises a main body, a blocking part, a hook line part, a side block and an inner sleeve, wherein the blocking part is positioned at the first end of the main body part; the hook line part is positioned at the first end of the main body part; the side block is arranged at the second end of the main body part, and a first included angle is formed between the side block and the main body part; the inner sleeve is arranged on the side block; when the blocking part is clamped to the outer side of coracoid, a guide needle can drill toward the hook line part in the inner sleeve in the first direction, and the first direction is not parallel to the plane of the main body part. With the adoption of the positioning device, the positioning accuracy and stability of tunnel constructing in acromioclavicular dislocation operation can be achieved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a positioning device for establishing a tunnel used in minimally invasive surgery for the treatment of acromioclavicular joint dislocation. Background technique [0002] With the progress of society and the development of medical level, minimally invasive surgery will become the mainstream. Arthroscopy technology has developed rapidly in recent years. The progress of technology is inseparable from the invention and creation of equipment. Good equipment can greatly reduce the difficulty of surgery and improve the quality of surgery. Bring greater benefits to patients. [0003] When minimally invasive arthroscopic surgery for dislocation of the acromioclavicular joint is used for reconstruction and fixation with the coracoclavicular ligament loop plate, a bone tunnel needs to be established in the clavicle and coracoid process, and the knee cruciate ligament reconstruction instrument...
