Fracture traction fixator capable of carrying out fracture traction fixation and rapid reduction simultaneously

Abstract

The invention discloses a fracture traction fixator capable of carrying out fracture traction fixation and rapid reduction simultaneously, and belongs to the technical field of orthopedic operative instruments. The fracture traction fixator is used for completing rapid reduction when carrying out fracture traction fixation. According to the technical scheme, a length-adjustable screw sleeve is arranged in the middle of a traction rod, the upper ends of two fixation rods are detachably and perpendicularly connected with the two ends of the traction rod respectively, the lower ends of the two fixation rods are universally connected with the upper portions of fixation collets respectively, and the lower portions of the two fixation collets are fixedly connected with bone fixation portions at the two ends of a fracture portion respectively. According to the fracture traction fixator, the fracture portion can be made to move towards the two ends by adjusting the length of the traction rod, and thus the overlap displacement of the fracture portion can be corrected; the rotation displacement of the fracture portion can be corrected by rotating the fixation collets; the traction rod, the fixation rods and the fixation collects are fast and convenient to connect, reduction and fixation can be simultaneously carried out, the effect of instant stabilization can be achieved, operative time is shortened, and the fracture traction fixator is especially beneficial to operations in emergencies.

Description

technical field [0001] The invention relates to a fracture traction fixer capable of quick reset and belongs to the technical field of orthopedic medical devices. Background technique [0002] Fractures of limbs and spine are common types of fractures in war injuries and social life. Exploring the most ideal fixation method for extremity fractures has always been a hot and difficult point in orthopedic work. There are some deficiencies in several fixation structures currently used, which cannot meet the clinical needs, as follows: the external fixator fixation operation is complicated, and the reduction cannot be completed at the same time, and it is difficult to meet the needs of rapid fixation of fractures on the battlefield; although braces and plaster fixation are installed Fast but difficult to effectively fix the fracture; the unique "angular stability" and "internal fixation bracket" of the locking plate can provide a stable fixation effect while protecting the perio...

There are some deficiencies in several fixation structures currently used, which cannot meet the clinical needs, as follows: the external fixator fixation operation is complicated, and the reduction cannot be completed at the same time, and it is difficult to meet the needs of rapid fixation of fractures on the battlefield; although braces and plaster fixation are installed Fast but difficult to effectively fix the fracture; the unique "angular stability" and "internal fixation bracket" of the locking plate can provide a stable fixation effect while protecting the periosteum from damage, but the operation requires spinal or general anesthesia , and cannot be realized on the battlefield; although interlocking intramedullary nails have been widely used clinically and have remarkable therapeutic effects, they do not have a reset function and are difficult to apply on the battlefield.
