Centrum universal reduction device for spinal operation of orthopedic department

Abstract

The invention discloses a centrum universal reduction device for a spinal operation of the orthopedic department, and particularly relates to the field of medical care equipment. The centrum universalreduction device comprises a main rod, supporting bases are connected to the two ends of the main rod, top bases are arranged at the tops of the supporting bases, transverse rods are arranged betweenthe two top bases, a detection top plate is arranged between the two transverse rods, side rods are arranged at the two sides of the detection top plate, and movable bases are arranged at the inner sides of the supporting bases. According to the centrum universal reduction device, through the arrangement of the side rods, positioning plates and clamping plates, the spines of patients are clamped,the device is adjusted at first, the positions of the side rods are adjusted according to different patients, hydraulic lifting rods are controlled to work and drive the positioning plates to move downwards, transmission motors are controlled to adjust the angles of the positioning plates, so that the two positioning plates position the good parts of the spines from the two sides, the positioningplates at the front and back expose to-be-excised lesion pyramids in the middle, then the clamping plates clamp the lesion pyramids from the two sides, and a doctor conveniently carries out the operation.

Description

technical field [0001] The invention relates to the technical field of medical care, and more specifically, the invention relates to a vertebral body universal reducer for orthopedic spinal surgery. Background technique [0002] With the advancement of medical technology, the operation of reduction and fixation after the complete resection of diseased or deformed vertebral bodies has been implemented clinically. During the implementation of this type of operation, reliable temporary fixation and accurate surgical reduction between the upper and lower segments of the diseased vertebral body or deformed vertebral body to be completely resected is an important part of the successful operation. At present, when this type of operation is performed clinically, the existing spinal internal fixator is used for temporary fixation between the upper and lower vertebral bodies of the diseased vertebral body or deformed vertebral body that needs to be completely resected. Instrument can...

[0005] Patent application publication number CN2102499744A discloses a vertebral body universal resetter for orthopedic spinal surgery. This patent utilizes the principle of leverage, universal knot and threaded rod adjustment mechanism, and quadrilateral frame structure. The operation is simple, labor-saving, and the surgical reset is easy and fast. Accurate, fast and reliable temporary fixation can shorten operation time, reduce operation risk, and improve operation quality. Many shortcomings, such as the process of directly locating the lesion cone, there will often be positioning errors and slight deviations in the position of the vertebral body after being stressed, which will affect the doctor's operation
