Minimally invasive repositor of tibial plateau collapse fracture block

Abstract

The invention discloses a minimally invasive repositor of a tibial plateau collapse fracture block, and belongs to the technical field of orthopedics department medical equipment. The minimally invasive repositor is used for performing minimally invasive reposition on a collapse fracture block in a tibial plateau joint. The technical scheme of the minimally invasive repositor is that a repositionplate is a disk, a diameter of the reposition plate is matched with a diameter of a minimally invasive drill hole, the front end of a top rod is connected with the bottom face of the reposition plate,and the rear end of the top rod is connected with a handle, the top rod is a flexional long rod, the top rod is made of a high molecular material or a spring, and a length of the top rod is greater than a length of the minimally invasive drill hole. The minimally invasive repositor initiates a tibial plateau collapse bone block reposition minimally invasive device, and provides a new route for treating and repositioning the tibial plateau collapse bone block through a minimally invasive operation. The minimally invasive repositor is simple in structure, convenient to use, and capable of avoiding the support and fixation of a long bone fracture plate after the reposition, reducing additional operative incisions and soft tissue injuries, greatly reducing the occurrence of complications, such as postoperative incision infection and dysfunction, simplifying a medical treatment process, saving medical resources, and relieving the medical burden of a patient.

Description

technical field [0001] The invention relates to a device used for minimally invasive reduction of intra-articular collapsed fracture fragments of the tibial plateau during operation, and belongs to the technical field of orthopedic medical devices. Background technique [0002] Tibial plateau fracture is a common intra-articular fracture in clinical practice, and it is mostly seen in middle-aged and young people who have suffered high-energy injuries. Due to the complex and changeable fracture morphology, clinical treatment is more difficult. The purpose of treatment for tibial plateau fractures is to restore the smoothness of the articular surface and the alignment of the lower limbs, firmly fix the fracture fragments, and avoid long-term complications such as postoperative traumatic arthritis and joint stiffness. The key step in the surgical treatment of tibial plateau fractures is to reduce the displaced fracture fragments. In order to obtain a good surgical field of vi...

AI Technical Summary

Problems solved by technology

The biggest problem existing in the current minimally invasive surgical methods is that minimally invasive reduction of intra-articular fractures can only be performed by drilling away from the fracture site, and the tunnel formed by the drilling can reach below the fracture block for jacking and reduction. The jacks are placed obliquely into the bone tunnel, and the insertion position is far away from the collapsed bone block. At the same time, the opening of the bone window is far away from the knee joint, which will cause a defect in the tibial shaft and seriously affect the overall stability of the tibia. After reduction, a long bone graft is required. The plate should be supported and fixed, otherwise iatrogenic tibial shaft fractures will easily occur
