Problems solved by technology

[0004] However, in current clinical applications, after the syndesmosis is reset with the help of reduction forceps, the placement of the inferior tibiofibular screw is estimated based on surgical experience, which inevitably leads to poor position of the inserted inferior tibiofibular screw, and even inferior tibiofibular screw failure. The screw is close to the posterior edge of the tibia and is not inserted into the tibia, resulting in poor surgical treatment effect and even leading to medical technology accidents

Embodiment Construction

[0028] In order to make it easier for those skilled in the art to understand the present invention, the specific implementation manners of the present invention will be described below with reference to the accompanying drawings.

[0029] Such as Figure 1-3 As shown, the lower tibiofibular syndesmosis reduction and screw insertion guide device includes an X-ray transparent resin chassis 1 and an ankle neutral fixation component 2 arranged on the X-ray transparent resin chassis 1, an ankle joint horizontal marker rod component 3, a lower The tibiofibular screw was placed into the spacing and angle component 4 and the inferior tibiofibular syndesmosis compression reduction component 5 .

[0030] The ankle neutral position fixation assembly 2 is used to promote the ankle joint to be in a neutral position relative to the X-ray resin chassis 1, and includes a bracket 21 fixed on the X-ray resin chassis, which is perpendicular to the bracket 21 and can be moved up and down on the b...

Abstract

The invention relates to the technical field of medical instruments, in particular to a tibiofibular syndesmosis reduction and screw placement guide device. The guide device comprises a base disc andan ankle neutral fixing assembly, an ankle joint horizontal marking rod assembly, a tibiofibular screw placement spacing and angle assembly and a tibiofibular syndesmosis pressurizing reduction assembly which are arranged on the base disc. By means of the tibiofibular syndesmosis reduction and screw placement guide device, tibiofibular screws can be placed reasonably with the placement position accuracy to 1mm and 1 degree, so that the tibiofibular screw placement accuracy is greatly improved, the surgical treatment effect is greatly improved, the occurrence of medical technical accidents is avoided, and the guide device is suitable for popularization and application in clinical medicine.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a syndesmotic reduction and screw insertion guide device. Background technique [0002] Ankle fractures with syndesmosis injuries are relatively common clinically, and 15-23% of ankle fractures with syndesmotic ligament injuries require precise reduction and fixation. If the treatment is not timely or inappropriate, chronic pain, joint instability and traumatic arthritis often remain, seriously affecting the function of the ankle joint. There are many methods of tibiofibular fixation, but as a simple and effective method, the fixation of inferior tibiofibular metal screw is still considered as the gold standard. [0003] At present, the most commonly used clinical treatment method is lateral fixation with AO cortical bone screws. For many years, the location and number of inferior tibiofibular screws have been the focus of controversy. With the deepening of various biom...
