Embodiment 1

[0036] Such as Figure 1 to Figure 5 As shown, this example proposes

[0037] A percutaneous patella fracture reducer, comprising a base 1 and several horizontal rods 3 arranged on the base 1 through a movable mechanism 2, the movable mechanism 2 includes a lifting mechanism 4 arranged on the base 1 and a lifting mechanism 4 arranged on the lifting mechanism 4 and The horizontal adjustment mechanism 5 that rises and falls with the lifting mechanism 4, the horizontal rod 3 moves in three-dimensional space by means of the horizontal adjustment mechanism 5 and the lifting mechanism 4, and the ends of several horizontal rods 3 facing the patella are pointed, and the pointed ends are used to pass through the skin and abut on the on the patella.

[0038] In this embodiment, in order to solve the problem in the related art that open reduction is required when the fracture of the patella is reduced, causing greater trauma to the patient. The concept of this application to solve the ...

Embodiment 2

[0063] Such as Figure 6 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes a percutaneous patellar fracture reducer, which is simpler in structure than that of embodiment 1, although it cannot adjust the precise angle.

[0064] It includes a base 1 and a number of horizontal rods 3 set on the base 1 through the movable mechanism 2. The movable mechanism 2 includes a lifting mechanism 4 set on the base 1 and a horizontal adjustment mechanism set on the lifting mechanism 4 and rising and falling with the lifting mechanism 4 5. The horizontal rods 3 move in three-dimensional space with the help of the horizontal adjustment mechanism 5 and the lifting mechanism 4. The ends of the several horizontal rods 3 facing the patella are pointed, and the pointed ends are used to pass through the skin and abut on the patella.

[0065] Further, the lifting mechanism 4 includes a vertical rod 6 arranged on the base 1, a slide block 7 which s...

Abstract

The invention relates to the technical field of medical instruments, and provides a percutaneous patella fracture repository. The percutaneous patella fracture repository comprises a base and a plurality of horizontal rods arranged on the base through a movable mechanism, the movable mechanism comprises a lifting mechanism arranged on the base and a horizontal adjusting mechanism arranged on the lifting mechanism and ascending and descending along with the lifting mechanism, the horizontal rods move in a three-dimensional space by means of the horizontal adjusting mechanism and the lifting mechanism, the ends, facing a patella, of the horizontal rods are sharp ends, and the sharp ends are used for penetrating through the skin to abut against the patella. By means of the technical scheme, the problem that in the prior art, when patella fracture reduction is conducted, incision reduction is needed, and a patient is seriously wounded is solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a percutaneous patella fracture reducer. Background technique [0002] The patella is the largest sesamoid bone in the human body. Patella fractures are caused by trauma. Violence directly acts on the patella or the quadriceps muscle contracts violently, resulting in the loss of the integrity of the patella. Patella fractures can be cured through general treatment and surgical treatment. The purpose of treatment for patella fractures is to restore the function of the knee joint, allowing patients to walk as soon as possible, and try to preserve the patella. [0003] Surgical treatment is the most common treatment method in the treatment of patella fractures. Generally, an incision needs to be made first, and the flap is opened upwards to see the fracture fragment of the patella. Hold the patella to reset the gapped patella. After the reduction is completed, Kirschner wir...
