Problems solved by technology

[0006] The disadvantages of the above two structures are: due to the small cross-sectional area of ​​the ribs, the ribs can only be fixed by the fixation plate or the bone plate, and the reduction and correction cannot be performed, so there is a problem of difficult or inaccurate reduction. When fixing, there is no corresponding positioning structure

Abstract

The invention belongs to the technical field of medical apparatuses for department of thoracic surgery, and in particular discloses a rib fracture reduction and fixation apparatus for department of thoracic surgery. The apparatus comprises an upper clamping plate and a lower clamping plate, wherein guide holes, a threaded hole and a first through hole are formed in the upper clamping plate; a first sliding groove is formed in the upper end face of the upper clamping plate; a locating mechanism is connected into the first sliding groove in a sliding mode; the locating mechanism comprises a supporting plate and splints; guide pillars are fixedly connected to the upper end face of the lower clamping plate; the upper ends of the guide pillars run through the guide holes; a second through hole is formed in the lower clamping plate; a screw rod is rotatably connected into the second through hole; the lower end of the screw rod runs through the lower clamping plate and then is provided with a limiting block; and the upper end of the screw rod runs through the threaded hole and is provided with a rotary piece. According to the rib fracture reduction and fixation apparatus provided by the invention, reduction is implemented on a fracture part by virtue of the upper clamping plate and the lower clamping plate, then a position of rib drilling is determined by virtue of the locating mechanism, and two sides of the fracture part are fixed by virtue of fixing plates, so that an operation integrating reduction, locating and fixation is implemented; and a postoperative recovery effect of a patient is enhanced.

Description

technical field [0001] The invention belongs to the technical field of medical instruments for thoracic surgery, in particular to a rib fracture fixation device for thoracic surgery. Background technique [0002] Thoracic surgery, as an important department in a general hospital, specializes in diagnosing and treating the thoracic cavity and its internal organs. According to statistics, the incidence of sternal fractures accounts for 1.0% to 5.5% of thoracic trauma, and the main causes are traffic accidents and construction accidents. It can occur anywhere on the sternum, mostly at the ribs. Rib fractures are different from extremity fractures. Limb fractures can be fixed not only by steel plates, but also through auxiliary fixation of the fracture position outside the body. However, rib fractures can only be fixed by internal steel plates, so the ribs are docked and the fractures are fixed accurately during surgery. The degree requirements are extremely high. [0003] At ...
