Embodiment Construction

[0031] To facilitate those skilled in the art to understand the present invention, the following in conjunction with the accompanying drawings illustrate a specific embodiment of the present invention.

[0032] as Figure 1 ~ Shown, a crushing calcane fracture closure reduction device, comprising a calcane fixation component 1, a calcane balloon extrusion component 2, a calcane traction component 3; a calcane fixation assembly 1 is used to fix the anterior calcane and tal bone, while being able to limit the calcane airbag squeeze assembly 2, the calcane balloon squeeze assembly 2 squeezes from both sides and bottom of the calcane and supports the calcane fracture site, and the calcane traction assembly 3 drags the upturned end of the calcaneal bone downward movement to the original position.

[0033] Calcaneal fixation assembly 1 comprises plate I 11 and plate II 12, plate I 11 and plate II 12 symmetrically disposed on both sides of the calcaneum, plate 11 and plate II 12 are distr...

Abstract

The invention belongs to the technical field of medical devices, and in particular relates to a closed reduction device for comminuted calcaneus fractures, comprising a calcaneus fixation assembly, a calcaneus airbag extrusion assembly, and a calcaneus traction assembly; the calcaneus fixation assembly is used to fix the calcaneus At the same time, it can limit the calcaneal airbag extrusion assembly. The calcaneal airbag extrusion assembly squeezes and holds up the fracture site of the calcaneus from both sides and the bottom of the calcaneus. The calcaneal traction assembly pulls the raised end of the calcaneus toward the Move down to the original position. The closed reduction device of the calcaneus of the present invention can reduce the comminuted calcaneal fracture without going through the lateral surgical incision, and then fix it percutaneously with Kirschner wire, bone cement or locking plate. Thereby reducing intraoperative bleeding and surgical incision-related complications.

Description

Technical field [0001] The present invention belongs to the technical field of medical devices, specifically relates to a crushing calcaneal fracture closure reduction device. Background [0002] Comminuted calcaneal fracture due to joint surface collapse, changes in the morphology of the calcaneum, etc., such as no surgery to restore normal calcaneal morphology, will lead to the occurrence of traumatic arthritis, heel pain when the patient walks, affecting the patient's daily life, and eventually need to perform heel distance joint fusion surgery. [0003] In X-ray examination: lateral positional film can clearly show the Bohler angle and Gissane angle, which reflects the degree of fracture compression; the normal Bohler angle ranges from 25 ° to 40 °, and once the Bohler angle is less than 15 °, it is considered to be a serious injury; The Gissane angle is a very important anatomical marker, which is extended by the lateral side of the anterior and posterior articular surface o...
