Problems solved by technology

However, in the existing operation of tibial transverse bone transfer technology, it is necessary to drill a hole on the tibia, cut off the bone block and then use the support to move the tibia. Drilling, osteotomy, and transfer on the tibia or bone increase the risk of surgery, while minimally invasive surgery has the advantages of less trauma, less pain, and faster recovery. If the tibial transverse bo

Abstract

The invention relates to a periosteum and parenchyma distractor. The periosteum and parenchyma distractor is characterized by comprising a periosteum and parenchyma support sheet and lifting devices,wherein one or more thread holes and lifting devices are arranged on the periosteum and parenchyma support sheet; and each lifting device comprises a spicule and a rotary sleeve, wherein the rotary sleeve sleeves the spicule, an external thread is formed in one end of the rotary sleeve, the external thread cooperates with the corresponding thread hole, when the rotary sleeve rotates, the periosteum and parenchyma support sheet can move along the axial direction of the spicule, and the periosteum and parenchyma support sheet is use for supporting periosteum. The periosteum and parenchyma distractor can slowly and automatically distract periosteum and parenchyma. The periosteum and the parenchyma are slowly distracted to enable proliferation and biosynthesis functions of cells to be stimulated. The self repair capacity of organisms is mobilized, the foot blood supply can be improved, and the ulcer healing can be promoted.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a stretcher for periosteum and soft tissue. Background technique [0002] Chronic non-healing wounds refer to wounds that have no tendency to heal after treatment for at least 1 month. According to global estimates, the prevalence of chronic wounds is about 1% to 2%, and the prevalence is higher in developing countries and people over 65 years old. At present, among the approximately 100 million person-times of skin, surgical incision and sinus wounds in China, about 30 million person-times develop into chronic refractory wounds on the body surface. The etiology of chronic wounds mainly includes metabolic diseases (diabetes), trauma, infection and burns, tumors, and vascular diseases of the lower extremities. Among them, the proportion of diabetes in metabolic diseases is increasing year by year. By 2008, the etiology of chronic wounds in domestic surveys was as high as ...
