Reciprocating feeding unit, orthopaedic screw placement mechanism, orthopaedic screw placement device and orthopaedic screw placement method

Abstract

The invention provides a reciprocating feeding unit, an orthopaedic screw placement mechanism, an orthopaedic screw placement device and an orthopaedic screw placement method. The orthopaedic screw placement device comprises a fixing clamp structure, a movable arm structure and the orthopaedic screw placement mechanism, wherein the orthopaedic screw placement mechanism comprises a sliding table mechanism, a telescopic mechanism, a probe swing mechanism and the reciprocating feeding unit; and the reciprocating feeding unit comprises a driving mechanism, a first roller, a second roller and a clamping mechanism. According to the reciprocating feeding unit, the orthopaedic screw placement mechanism, the orthopaedic screw placement device and the orthopaedic screw placement method, the technical problems that in the prior art, a doctor manually punches holes in the pedicle by using a hand cone and a Kirschner wire according to experience, and then various uncertain conditions occur in the pedicle screw placement process are solved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a reciprocating feeding unit, an orthopedic nail setting mechanism, a device and an orthopedic nail setting method. Background technique [0002] Congenital scoliosis is a serious congenital deformity in children. Congenital scoliosis is divided into three types: vertebral body malformation, poor segmentation and mixed type. The deformity of the vertebral body causes the spine to bulge and rotate sideways or front and back, and gradually aggravates with the growth of the spine. In addition to the deformity of the body, the impact on the child is more seriously affecting the heart and lung function, organ function and spinal cord function of the child, which seriously hinders the growth and development of the child. Congenital scoliosis is often accompanied by other systemic deformities, such as spinal canal and spinal cord abnormalities, urinary system deform...

AI Technical Summary

Problems solved by technology

[0010] In view of this, the present invention aims to propose a reciprocating feeding unit, an orthopedic screw setting mechanism, a device, and an orthopedic screw setting method, which solves the problem of manual screwing on the pedicle by doctors using hand awls and Kirschner wires in the prior art. Holes, which in turn lead to technical problems in various uncertain situations during the placement of pedicle screws;

[0011] It further solves the technical problem that expensive equipment and special instruments are needed in the pedicle screw internal fixation in the prior art, and the operation is relatively complicated;

[0012] And it solves the technical problems of poor fixation effect, unsatisfactory orthopedic effect, and damage to surrounding important blood vessels and nerves caused by the traditional manual nail placement method
