Condylar fracture reduction device with navigation auxiliary function

Abstract

The invention discloses a condylar fracture reduction device with a navigation auxiliary function. The condylar fracture reduction device with the navigation auxiliary function comprises a head and a handle, wherein the top end of the head is in the shape of a fork with an opening; the top end of the handle is connected with the bottom end of the head; a navigation seat for placing a navigation ball is arranged at the bottom end of the handle; and a holding part for an operator to hold is arranged on a side of the handle. Risks of extra operative wound and facial nerve injury are reduced, meaningless operative wound and excessive separation are avoided, and damage risks of nerves and blood vessels are reduced. Meanwhile, the idiomatical prolate shape of the conventional vessel clamp or condylar reduction forceps is changed, the basic state of an ascending limb decoherence apparatus is used, an arc-shaped fork structure is designed again according to the anatomical shape feature of a mandibular condyle, and reduction of condylar fracture, particularly inwards shifted condylar fracture, can be carried out effectively. The condylar fracture reduction device with the navigation auxiliary function is relatively simple to operate and easy to popularize.

Description

technical field [0001] The invention relates to a medical auxiliary device, in particular to a condyle fracture resetter with navigation auxiliary function. Background technique [0002] Mandibular condyle fracture is one of the most common fracture types in the oral and maxillofacial region, and its incidence can account for 25% to 50% of all mandibular fractures. Its clinical manifestations are mandibular dysfunction and occlusal disorder, and untimely or unreasonable treatment can lead to serious complications including joint ankylosis and mandibular dysplasia. In recent years, with the continuous improvement of the surgical level and strong internal fixation techniques, many scholars have begun to prefer to perform surgical treatment for a considerable number of cases with severe displacement. [0003] During surgical reduction, an open incision is usually required to expose the fracture fragment and reduce it. The exposure of the fracture fragments mainly depends on t...

AI Technical Summary

Problems solved by technology

To be able to locate and expose the fracture fragments, the surgeon sometimes has to extend the incision and perform extensive dissection, which not only results in a more pronounced surgical scar, but also greatly increases the risk of damage to important anatomical structures such as the facial nerve and blood vessels

[0005] The locking teeth of ordinary condylar reduction forceps and vascular forceps cannot clamp the condyle very well, especially for some inwardly displaced condylar fracture fragments. For such cases, the surgeon Had to expend a lot of force on the condyle itself to keep the fracture fragments from falling off
