Limb reestablishment shape righting adjustment controllable external fixation stent

Abstract

The invention discloses a limb reestablishment shape righting adjustment controllable external fixation stent. The stent comprises a 360-degree angle shape righting nail clip, a stent axial up-and-down controllable adjusting nail clip, a stent unilateral controllable angle nail clip, a common nail clip and a guide rod. The stent is individually and randomly combined according to the specific conditions of patients by abiding by the mechanical principle, and the stent can meet requirements of any patient with limb malformation and be adjusted later. The stent can be pressurized, lengthened, rotated, bent and the like according to open comminuted fractures or bone defects. The stent is pre-placed after clinical assessment, the fractures can be later adjusted, the operation time is shortened, blood loss or iatrogenic injuries are reduced, and complex fractures are changed into simple fractures. Secondary operations caused by bone defects or force line deviations are reduced, the stability and flexibility of the external fixation stent are better exerted in fracture and shape righting treatment, the operation frequency of doctors is reduced, the operation time of the doctors is shortened, the cost of the patients is reduced, and the disease courses of the patients are shortened.

Description

technical field [0001] An orthopedic controllable external fixation bracket for limb reconstruction. Background technique [0002] Usually the fixation bracket is to drill the two ends of the fracture with needles or nails, and then fix the needle penetrating the fracture on the external fixator outside the skin, which has the following functions: 1) It can maintain a good reduction of the fracture end; 2) It can be retracted Both ends of the backbone are used to lengthen the limbs; 3) Compression techniques can be used to promote fracture healing; 4) Early angular deformities and rotational deformities can be corrected, such as old fractures. [0003] However, in the process of limb reconstruction, due to the inaccurate placement of bone screws, the vertical displacement or angle deviation of the backbone is caused. The existing fixed brackets cannot accurately adjust the deviation of displacement and angle in solving this problem, and for congenital In special cases such ...

Problems solved by technology

[0003] However, in the process of limb reconstruction, due to the inaccurate placement of bone screws, the vertical displacement or angle deviation of the backbone is caused. The existing fixed brackets cannot accurately adjust the deviation of displacement and angle in solving this problem, and for congenital Or bone deformities caused by trauma and the resulting C type, O In special cases such as deformed legs and ankle joints, there is no effective limb reconstruction fixation bracket
