Locking external fixation device for treatment of fracture of distal radius

Abstract

The invention relates to an external fixation locking fixing device for treatment of fracture of distal radius, belonging to the technical field of medical instruments. The locking external fixation device comprises a frame body and screws, the frame body comprises a T-shaped fixing part and a strip-shaped fixing part, the T-shaped fixing part and the strip-shaped fixing part are uniformly provided with threaded holes, the threaded holes are matched with threads of the tail parts of the screws so as to enable the T-shaped fixing part to be fixed on a back side bone block of the distal radius, and the strip-shaped fixing part is fixed on the radius side of the distal radius so as to enable the fracture of the distal radius to realize diaplasis locking. By using the locking external fixation device, the trauma is small, the hemorrhage is less, the incision is reduced manifold, and the cicatrix is small and attractive; and the operative complications are obviously reduced. Taking out by second operation is not required, so that hospitalization costs are saved for a patient. Moreover, the locking external fixation device is light in weight, the patient suffering from less pain, and the locking external fixation device is conducive to rehabilitation of the patient. According to the locking external fixation device, the screw path injury is small, the screw path complications are fewer, and the operative safety is improved; and as the fixation does not cross a joint, the operative interference with the wrist joint is reduced.

Description

technical field [0001] The invention relates to an external fixation locking and fixing device for the treatment of distal radius fractures, belonging to the technical field of medical devices. Background technique [0002] Distal radius fractures are common fractures. Surgical treatment is one of the main treatment methods. The purpose of treatment is to reduce and fix the fracture site. There are two kinds of fixation methods: internal fixation and external fixation. Internal fixation using steel plates and screws as materials is currently the main clinical treatment method. The disadvantages of internal fixation are large surgical trauma, long incision, and obvious scars. , some patients need a second operation to remove it. For the elderly, especially those who take anticoagulants such as aspirin, open reduction and internal fixation surgery has clear surgical risks, which greatly limits the application of internal fixation; external fixation is the safest option for tre...

Internal fixation using steel plates and screws as materials is currently the main clinical treatment method. The disadvantages of internal fixation are large surgical trauma, long incision, and obvious scars. , some patients need a second operation to remove it. For the elderly, especially those who take anticoagulants such as aspirin, open reduction and internal fixation surgery has clear surgical risks, which greatly limits the application of internal fixation; external fixation is the safest option for treatment. option, the structure of the traditional external fixator such as figure 1 As shown, it mainly includes an elongated frame body 1, a plurality of clamping screws 2, fixing screws 3 and movable joints 4; in order to adapt to the bone size of different groups of people, the length of the frame body can be adjusted, and the fracture fixing screws 3 are composed of clamping screws 2 fixed and adjustable length; movable joints can adjust the angle

However, the traditional external fixator is bulky and bulky, the operation is complicated, the fixation effect is poor, it is easy to loosen, and it is fixed across the joint, so that the function of the wrist joint is often affected. Therefore, the traditional external fixator is used in distal radius fractures. There are also obvious deficiencies in the treatment of
