Problems solved by technology

The establishment of the pedicle is mostly established by the surgeon based on the general direction of the pedicle, and using the drilling device to drill tentatively based on the feel and experience. It is easy to penetrate the pedicle, which will not only reduce the internal fixation strength of the screw, but may also damage the channel. surrounding tissues, causing pedicle cortex rupture, spinal cord and nerve root injury, blood vessel and visceral injury, etc.

Abstract

The invention discloses a drilling device and method for pedicle of vertebral arch with force feedback. The problems in the prior art are solved so that pedicle of vertebral arch is not easily broken, the internal fixation strength is not reduced and pedicle cortex is not fractured. The drilling device is reasonably arranged and provides a reference for accurate implantation of a pedicle screw. The beneficial effect is provided for effective establishment of a pedicle screw channel. The technical scheme is characterized in that the drilling device comprises a drilling rod; the head of the drilling rod is provided with a drilling bit; the drilling bit is provided with a force sensing resistor; the tail of the drilling rod is provided with an oscillating circuit; the oscillating circuit penetrates through a lead wire arranged in the drilling rod to be connected with the force sensing resistor; an alarm lamp is arranged in an annular oscillating circuit; the tail of the drilling rod is arranged in a handle; and the handle is detachably connected with the drilling rod.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a pedicle drilling device and method with force feedback. Background technique [0002] Pedicle screw internal fixation is a common surgical method for clinical spine surgery, such as spondylolisthesis, lumbar fracture, lumbar degenerative disease and other diseases, and has achieved a relatively satisfactory effect. Based on the anatomical characteristics of the pedicle, the implanted screw must pass through the narrow bony canal of the pedicle along the long axis of the pedicle according to the correct sagittal plane angle and horizontal plane angle. At present, it mainly relies on anatomical landmarks to determine the screw entry point. Auxiliary instruments such as Kirschner wires and pedicle probes are used to establish the screw path, and the position of the guide pin is confirmed through C-type X-ray machine projection. The establishment of the pedicle is most...
