Problems solved by technology

The rod bending device in the prior art cannot strictly control the angle of the rod, either the angle is not enough to achieve the purpose of orthopedics, or the angle of the rod is too large and needs to be bent back
This prolongs the operation time and is also a kind of damage to the metal rod connected to the pedicle in the USS internal fixation system.

Abstract

The invention relates to a bending device for a fixing rod in the spine vertebral pedicle and a working method of the bending device, and belongs to the field of medical instruments. The bending device comprises an installing plate which is round, and a fixed barrel and a movable barrel are arranged on the upper side face of the installing plate; the fixed barrel is fixed to the installing plate,the lower portion of the right end of the movable barrel and the lower portion of the left end of the fixed barrel are hinged together, the hinging point of the movable barrel and the fixed barrel islocated in the circle center of the installing plate, the fixed barrel is fixed to the installing plate, and the interior of the fixed barrel is hollow and is a fixing hole. In this way, the angle ofthe bent rod can be accurately and strictly controlled, and is adjustable, adaptability is high, and operation efficiency is greatly improved.

Description

technical field [0001] The invention relates to a spinal pedicle internal fixation rod bending device and a working method thereof, belonging to the field of medical instruments. Background technique [0002] At present, the clinical treatment of scoliosis correction, spinal fracture, dislocation and other diseases mostly adopts the pedicle screw fixation system (USS internal fixation system) - the internal fixation pedicle screw of the spine is fixed on the connected metal rod for reduction, fixed. Because the physiological curvature of the spine is different in each vertebral body stage, the bending angle of the metal rod connected to the pedicle screw in the internal fixation USS system is different. The rod bending device in the prior art cannot strictly control the angle of the rod, either the angle is not enough to achieve the purpose of orthopedics, or the angle of the rod is too large and needs to be bent back. This prolongs the operation time, and is also a kind o...
