Problems solved by technology

[0002] Ankle fractures are common intra-articular fractures in clinical practice, and surgical reduction requires anatomical reduction; however, due to the special anatomical structure of the ankle joint, no matter whether it is open reduction or closed reduction, the anatomical reduction of the articular surface cannot be guaranteed by simply using the C-arm during surgery , especially the reduction and fixation of the posterior ankle and inferior tibiofibular syndesmosis, which affects the surgical effect and increases the incidence of traumatic arthritis in patients
[0003] The application of arthroscopic assisted reduction can accurately confirm the fracture of articular cartilage and judge the reduction of the articular surface, clarify the injury of the ankle ligament, and can find the advantages of removing the remaining bone and articular cartilage fragments in the joint, which has attracted more and more clinical attention; However, the ankle joint space is small, and it is difficult to reveal the posterior ankle and complete the reduction and fixation of the posterior ankle under arthroscopy, so it is difficult to popularize and apply in clinical practice.

Abstract

The invention provides an auxiliary device for treating ankle fracture under an arthroscope and an operation method thereof. The auxiliary device comprises a first auxiliary mechanism and a second auxiliary mechanism, and the first auxiliary mechanism comprises two retraction reduction assemblies; each retracting reduction assembly comprises a retractor, a first extension socketed pipe, a second extension socketed pipe, a retracting kit, a reduction pull pipe and a reduction kit; the second auxiliary mechanism comprises a retractor, an expansion guide kit, a first guide inner core, a second guide inner core and a hollow wrench. By means of the auxiliary device, the fractured posterior ankle and the reduction condition of the posterior ankle can be smoothly shown under the arthroscope, then operation personnel can conduct reduction and fixing work on the fractured posterior ankle according to the shown condition of the arthroscope, and the clinical operation effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an auxiliary device for arthroscopic treatment of ankle fractures and an operating method thereof. Background technique [0002] Ankle fractures are common intra-articular fractures in clinical practice, and surgical reduction requires anatomical reduction; however, due to the special anatomical structure of the ankle joint, no matter whether it is open reduction or closed reduction, the anatomical reduction of the articular surface cannot be guaranteed by simply using the C-arm during surgery , especially the reduction and fixation of the posterior malleolus and inferior tibiofibular syndesmosis, which affects the surgical effect and increases the incidence of traumatic arthritis in patients. [0003] The application of arthroscopic assisted reduction can accurately confirm the fracture of articular cartilage and judge the reduction of the articular surface, clarify the ...
