Navigation plate for individually assisting complete anatomical reconstruction of coracoclavicular ligament and manufacturing method thereof

Abstract

The invention relates to a navigation plate for individually assisting complete anatomical reconstruction of a coracoclavicular ligament and a manufacturing method thereof. According to the invention, based on a base, each bone tunnel catheter is designed in a preset direction according to the central positions of a trapezoid ligament and a conoid ligament at processus coracoideus scapularis and clavicle attachment footprint; the above process is implemented in three-dimensional reconstruction software through combination of anatomical markers and calculation, and it can be ensured that the positions of the trapezoid ligament and the conoid ligament completely conform to anatomical positions, the direction of a tunnel is consistent with the designed direction, and the accuracy and safety of an operation are ensured; the bone tunnel catheter of the trapezoid ligament and the bone tunnel catheter of the conoid ligament are built on the same base, so the built tunnel is more accurate; and in addition, the base is completely attached to the bone surfaces of the clavicle and the coracoid, the central positions of ligament attachment footprints is marked, and the catheters in the direction of the bone tunnel are connected with the base into a whole, so the bone tunnel can be accurately established.

Description

technical field [0001] The invention relates to a navigation board and a manufacturing method for personalized auxiliary complete anatomical reconstruction of the coracoclavicular ligament, belonging to the technical field of medical devices. Background technique [0002] Dislocation of the acromioclavicular joint is common in clinical practice. The coracoclavicular ligament reconstruction technique is widely used in the treatment of dislocation of the acromioclavicular joint. The coracoclavicular ligament is composed of two ligaments, the trapezoidal ligament and the conical ligament. These two ligaments have different anatomy. structure and function. Currently, the commonly used single-bundle reconstruction technique is only an approximate anatomical reconstruction of the clavicle insertion, and cannot completely replace the functions of the trapezoidal and conical ligaments. A few reported double-bundle reconstructions of the coracoclavicular ligament are not complete rec...

AI Technical Summary

Problems solved by technology

During the operation, measuring methods such as straightedge and angler are used to determine the central area of ​​the imprint of the trapezoidal ligament and conical ligament on the clavicle and coracoid process and create a bone tunnel. rate has some influence

Although the computer navigation technology can accurately assist the realization, the popularity of the navigation system is still not high, and the price is too high to effectively apply and promote the complete anatomical reconstruction of the coracoclavicular ligament in clinical practice. Therefore, there is an urgent need for a A new technology that guarantees surgical results without relying on navigation systems
