Problems solved by technology
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
[0003] However, due to the lack of intraoperative testing equipment, the stability of the tibiofibular syndesmosis is generally assessed by the ankle external rotation test and the fibular traction (Hook or Cotton) test in the existing surgery.
However, in practice, it is found that the above-mentioned experimental results are subject to judgment, and there will be large errors due to different doctors' experience, which will mislead the treatment.

Embodiment Construction
[0022] 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.
[0023] Such as Figure 1-2 As shown, the intraoperative detection device for the stability of the inferior tibiofibular syndesmosis includes an X-ray transparent resin chassis 1 and a calf fixation mechanism 2, a lower tibiofibular syndesmosis tension mechanism, and a foot fixation mechanism 4 that are sequentially arranged on the X-ray transparent resin chassis 1 And lower tibiofibular syndesmosis and fibula torsion mechanism.
[0024] The lower tibiofibular syndesmosis torsion mechanism is used to observe the stability of the lower tibiofibular syndesmosis through X-ray under a certain torsion angle. It includes a torsion component 6 and a two-dimensional universal torsion bracket 3 connected to the torsion component 6 . The torsion assembly 6 i...

The invention relates to the technical field of medical instruments, in particular to an intraoperative detection device for the stability of tibiofibular syndesmosis. The device comprises a chassis and a shank fixing mechanism, a tibiofibular syndesmosis tension mechanism, a foot fixing mechanism and a tibiofibular syndesmosis fibula torsion mechanism which are sequentially arranged on the chassis; the tibiofibular syndesmosis tension mechanism comprises a torsion assembly and a two-dimensional universal torsion stent connected with the torsion assembly; the foot fixing mechanism comprises afoot fixing plate, a toe fixing frame arranged at the top of the foot fixing plate and a foot bracket arranged in an arc-shaped structure at the bottom of the foot fixing plate; the tibiofibular syndesmosis fibula torsion mechanism comprises a tension assembly and a two-dimensional universal tension stent connected with the tension assembly. The force for detecting the stability of the tibiofibular syndesmosis can be checked both in direction and in size, so that the accuracy of the stability detection of the tibiofibular syndesmosis is remarkably improved, the occurrence of missed diagnosis and misdiagnosis is greatly avoided, and the intraoperative detection 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 an intraoperative detection device for the stability of the inferior tibiofibular syndesmosis. Background technique [0002] Ankle fractures with syndesmotic syndesmotic injuries are relatively common clinically, and about 15-23% of them will result in syndesmotic ligament injury and syndesmotic instability, requiring 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. [0003] However, due to the lack of intraoperative detection equipment, the stability of the tibiofibular syndesmosis is generally assessed by the ankle external rotation test and the fibular traction (Hook or Cotton) test in existing operations. However, in practice, it has been found that the above-mentioned experimental results are subject to judgment w...
