Problems solved by technology

Internal fixation using steel plates and screws as materials is currently the main clinical treatment method. The disadvantages of traditional internal fixation are large surgical trauma, long incision, and obvious scars. After the dislocation heals, the internal fixation plate is located under the skin, which is very obvious. cause, often requiring secondary surgery to remove

Embodiment Construction

[0021] The locking external fixation device proposed by the present invention for the treatment of acromioclavicular joint dislocation includes an L-shaped fixture 1 and a screw 6, and the structure of the L-shaped fixture is as shown in Figure 1, wherein Figure 1 (a) is an L-shaped fixture Structural schematic diagram, Fig. 1(b) is a side view of the L-shaped fixing part shown in Fig. 1(a). Threaded holes 2 are evenly distributed on the L-shaped fixing part 1, and the threaded holes 2 match the thread of the screw tail end 4 of the screw 3, such as figure 2 As shown, the L-shaped fixture 1 is fixed to the injured limb through the screw 6 .

[0022] In the aforementioned locking external fixation device, the L-shaped fixing member 1 can be made of any material among stainless steel, aluminum alloy, titanium alloy, carbon steel or carbon fiber.

[0023] The L-shaped fixing part in the above-mentioned locking external fixing device can be a cuboid or a cylindrical body, and its...

Abstract

The invention relates to a locking outer fixing device used for treatment of dislocation of acromioclavicular joints and belongs to the technical field of medical instruments. The locking outer fixing device comprises an L-shaped fixing member and screws; the fixing member is evenly provided with threaded holes which are matched with the tails of the screws; the L-shaped fixing member enter an injured limb through the screws. The L-shaped fixing member is made of any material of stainless steel, aluminium alloy, titanium alloy, carbon steel or carbon fiber. By means of the locking outer fixing device of the invention, the wound is small with less bleeding, notches are reduced by times and scars are small and beautiful. The operation complication is obviously reduced and there is no need of a second operation for removal so as to avoid the risk of a secondary operation and save medical cost for patients. The device is smaller than traditional fixing frames in volume and is light; pain in patients is reduced and the device is good for the rehabilitation of patients. By means of the locking outer fixing device, screw path damage is small and screw path complication is less, and the safety of operation is increased.

Description

technical field [0001] The invention relates to a locking external fixation device for the treatment of acromioclavicular joint dislocation, which belongs to the technical field of medical instruments. Background technique [0002] Dislocation of the acromioclavicular joint is a common orthopedic injury. Severe dislocation requires surgical treatment. The purpose of treatment is to reset and fix the dislocated part. The existing fixation methods include internal fixation and external fixation. The traditional Kirschner wire fixation method is rarely used because of its unreliable fixation and high failure rate. Internal fixation using steel plates and screws as materials is currently the main clinical treatment method. The disadvantages of traditional internal fixation are large surgical trauma, long incision, and obvious scars. After the dislocation heals, the internal fixation plate is located under the skin, which is very obvious. Causes often require secondary surgery t...
