Embodiment 1

[0041] See figure 1 , figure 1 It is a structural schematic diagram of the intraoperative spinal rod customization system according to Embodiment 1 of the present invention. The intraoperative spinal rod customization system includes a feeding mechanism 1 , a measuring and positioning mechanism 2 , a cutting mechanism 3 , a bending mechanism 5 and a controller 8 . The controller 8 is the control core of the intraoperative spine connecting rod customization system, and its main function is human-computer interaction and control output. The user (doctor) can input the relevant parameters of the currently required customized connecting rod, and the control The device 8 controls other modules (including the feeding mechanism 1, the measuring and positioning mechanism 2, the cutting mechanism 3, the bending mechanism 5, etc.) to perform corresponding operations after calculating and processing the parameters input by the user; the feeding mechanism 1 The function of the connectin...

Embodiment 2

[0048] The intraoperative spinal rod customization system of this embodiment includes a feeding mechanism, a measuring and positioning mechanism, a cutting mechanism, a bending mechanism and a controller.

Abstract

The invention relates to an intraoperative spine connective bar customizing system and method. The intraoperative spine connective bar customizing system comprises a feeding mechanism, a measuring andpositioning mechanism, a cutting mechanism, a bending mechanism and a controller, wherein the controller is used for performing man-machine interaction and controlling output, and is used for controlling the feeding mechanism, the measuring and positioning mechanism, the cutting mechanism and the bending mechanism; the system also comprises a marking mechanism; the system also comprises an imageacquiring mechanism; and the controller also comprises an image transformation unit, a 3D reconstruction unit, a connective bar simulating and generating unit and a connective bar parameter acquiringunit. Through the adoption of the intraoperative spine connective bar customizing system disclosed by the invention, the conventional situation that at present, a connective bar is artificially customized is breakthrough, making up the defects in the connective bar customizing respect of a spine surgical operation in a long time is facilitated, the parameterization customizing of the connective bar is completed in an accurate, quick and one-time manner, and high-complexity connective bar customizing can be completed.

Description

technical field [0001] The invention relates to the fields of orthopedics and spinal surgery, in particular to a system and method for customizing pedicle and lateral mass screw connecting rods used in spinal surgery, which are used in customizing pedicle screw or lateral mass screw fixation systems for patients connecting rod. Background technique [0002] Normal people have three physiological curvatures in the spine. For patients with functional degeneration of the spine or spinal deformities, such as cervical curvature disappearance or recursion, lumbar disc herniation, scoliosis, kyphosis, etc., it needs to be repaired by orthopedic surgery . In orthopedic surgery, after completion of decompression, pedicle screw or lateral mass screw placement, it is necessary to use pre-bent connecting rods for fixation. Since each patient's spine sequence and curvature are different, and the range of fixation and correction angle are also different, clinically, mechanical pre-bendi...
