Description

A condylar fracture reducer with navigation aid function

technical field

The utility model relates to a medical auxiliary device, in particular to a condylar fracture resetter with a navigation auxiliary function.

Background technique

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.

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 the preoperative auxiliary examination (such as CT, etc.) and the experience and judgment of the surgeon; and the conventional condylar reduction forceps or ordinary vascular forceps are usually used in the reduction process.

Due to the special organizational structure of the condyle itself, individual differences in patients and the different magnitude and direction of external force acting on the mandible, it is sometimes very difficult to locate the fracture fragment. In order 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 leads to a more obvious surgical scar, but also greatly increases the risk of damage to important anatomical structures such as the facial nerve and blood vessels.

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 spend a lot of effort for the clamping of the condyle itself to prevent the fracture fragments from falling off.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a condylar fracture reducer with a navigation auxiliary function, which can effectively locate the condylar fracture position and reduce trauma.

The utility model is realized through the following technical solutions. The utility model comprises a head and a handle. The top of the head is a fork with an opening. The top of the handle is connected to the bottom of the head. The handle The bottom end of the handle is provided with a navigation seat for placing the navigation ball, and the side of the handle is provided with a grip part for the operator to hold.

The top end of the handle and the bottom end of the head are connected by bolts. The cleaning head can be replaced after use to ensure medical hygiene.

The head is an arc structure. The arc-shaped structure can directly act on the fracture block, and the fracture block can be reset by the operator's thrust.

The arc is half of an ellipse with a major diameter of 15 mm and a minor diameter of 10 mm along the major diameter direction. The design length of the arc can meet the needs of reset and match the arc of the human mouth.

The navigation seat at the bottom end of the handle is connected to the navigation ball by bolts. The existing navigation technology can be used to assist in effectively locating the location of the condylar fracture.

The navigation seat is a cylindrical structure with threads. Can be used to fix the navball.

Compared with the prior art, the utility model has the following advantages: the utility model can use navigation technology to assist in effectively locating the position of the condylar fracture fragment during the operation, which greatly reduces the difficulty of finding the condylar fracture fragment during the operation, and improves the operation efficiency. efficiency. Reduce the risk of additional surgical trauma and facial nerve injury, avoid unnecessary surgical trauma and excessive separation, and reduce the risk of nerve and blood vessel injury. At the same time, the usual flat and long shape of the conventional vascular forceps or condylar reduction forceps was changed, and the basic shape of the ascending branch dissector was adopted instead. According to the anatomical shape characteristics of the condyle, the arc-shaped fork-shaped structure was redesigned, which can effectively Condyle fractures, especially condyle fractures displaced inwardly, are relatively simple to operate and easy to popularize.

Detailed ways

The following is a detailed description of the embodiments of the present utility model. This embodiment is implemented on the premise of the technical solution of the present utility model, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present utility model is not limited to the following the described embodiment.

As shown in Figures 1 and 2, this embodiment includes a head 1 and a handle 2, the top of the head 1 is fork-shaped with an opening, the top of the handle 2 is connected to the bottom of the head 1, The bottom end of the handle 2 is provided with a navigation seat 21 for placing a navigation ball, and the side of the handle 2 is provided with a gripping portion 22 for the operator to hold.

The top end of the shank 2 and the bottom end of the head 1 are connected by a bolt 3 . The cleaning head 1 can be replaced after use to ensure medical hygiene. The head 1 has an arc-shaped structure, which is half of an ellipse with a long diameter of 15 mm and a short diameter of 10 mm along the long diameter direction, matching the curvature of the oral cavity. The arc-shaped structure can directly act on the fracture block, and the fracture block can be reset by the operator's thrust. The bottom end 21 of the shank 2 is connected to the navigation seat 21 through the bolt 3, and the navigation seat 21 is a threaded cylindrical structure. The existing navigation technology can be used to assist in effectively locating the location of the condylar fracture.

When in use, the doctor holds the holding part 22 of the handle 2, and the navigation ball rotates to drive the entire resetter to move, and the arc-shaped head 1 directly acts on the fractured part, and then promotes the reduction of the fractured part. It can be combined with navigation technology to effectively locate the position of the condylar fracture fragment during the operation, reducing the risk of additional surgical trauma and facial nerve injury; at the same time, it changes the reset mode, reduces the difficulty of reset, and improves the operation efficiency.
