Problems solved by technology

[0004] At present, in order to adapt to the individual characteristics of patients, the operation often relies on the doctor's surgical experience to place the nails, which is prone to subjective deviations. Deviations occur during the nail placement process, which makes it impossible to establish a reasonable and effective channel, which in turn affects the surgical effect, increases the surgical risk, and prolongs the life of the surgery. operation time

Abstract

The invention relates to a medical instrument for an orthopedic operation, and particularly relates to a screw placement device in the orthopedic operation. The device comprises an acromioclavicular joint screw placement device, a cervical vertebra pedicle screw placement device and a thoracolumbar vertebra pedicle screw placement device; and each of the acromioclavicular joint screw placement device, the cervical vertebra pedicle screw placement device and the thoracolumbar vertebra pedicle screw placement device comprises a part guide frame, the part guide frames are used for installing part positioning mechanisms and part screw placement guide pipes. Due to the implementation of the technical scheme, the device is simple in structure, convenient to use and low in cost, subjective deviation of an operator during screw placement is avoided, the operation risk is reduced, the operation time is shortened, the labor cost and the time cost are reduced, a more efficient and convenient replacement scheme is provided for the operator to carry out reduction operation on the acromioclavicular joint, and the device is suitable for wide popularization and application.

Description

technical field [0001] The present application relates to a medical device for orthopedic surgery, in particular to an orthopedic nail placement device. Background technique [0002] At present, in orthopedic surgery, it is often necessary to drive steel nails into specific parts of the bone to facilitate the rapid recovery of patients. [0003] For example, in the treatment of some dislocations of the acromioclavicular joint, screws need to be driven into the coracoid process of the scapula through the distal end of the clavicle; some cervical spine fractures need to be treated with vertebroplasty, and pedicle auxiliary positioning is required when fixing pedicle screws. Complete the insertion of cervical pedicle screws; during thoracolumbar spine surgery, thoracolumbar pedicle auxiliary positioning is required when fixing thoracolumbar pedicle screws, and then complete the insertion of thoracolumbar pedicle screws. [0004] At present, in order to adapt to the individual ...
