Description
Technical Field
The invention relates to a restorer, in particular to a percutaneous minimally invasive fracture restorer, and belongs to the technical field of clinical medical bone surgery.
Background
The basic principle of fracture treatment is reduction, fixation and functional exercise, obviously the reduction is the starting link of the whole fracture treatment, and the reduction effect directly influences the internal fixation implantation effect, thereby determining the fracture treatment effect. Common fracture reduction techniques include manipulation and incision reduction, and fracture reduction and firm fixation are the most ideal conditions for orthopedics doctors to realize fracture dissection reduction under the non-invasive premise. However, in reality, the noninvasive manual reduction is often difficult to achieve the effect of functional reduction, and even if the real-time good reduction of fracture is realized, fracture displacement can also occur quickly under the action of muscle traction, so that the reduction is invalid. Compared with manual reduction, the reduction is easier to realize functional reduction and even anatomical reduction, and also is easy to realize internal fixation of fracture, however, the soft tissues and the blood circulation of the fracture are damaged, obvious negative effects are caused on fracture healing, and improper reduction and fixation of fracture are often the direct causes of bone nonunion, bone necrosis and bone defect. The fracture anatomic reduction and firm fixation are realized on the premise of little damage or even no damage to blood circulation, which is an important problem facing the fracture of the old diseases. It can be said that minimally invasive fracture fixation is only possible if minimally invasive fracture reduction is achieved first, and current fractures are reduced by means of various auxiliary instruments such as a wide variety of reduction forceps. The purpose of minimally invasive fracture reduction is not achieved, mainly because the minimally invasive fracture does not achieve good holding force on the fracture pieces, and even in incisional reduction, some deep fractures are not easy to achieve anatomic reduction by using common reduction forceps, which is also related to insufficient holding force.
