Abstract

The utility model discloses an orthopaedic piercer for operation, belonging to the technical field of medial equipment. The piercer comprises a taper bit, a drill stem, a connecting rod and a handle, wherein the handle is fixed at the rear end of the connecting rod; the drill stem with a reduced diameter is fixed at the front end of the connecting rod; and the taper bit is arranged at the front end of the drill stem. The piercer is used for screw fastening operation at a pedicle of a vertebral arch of a thoracolumbar spine in orthopaedics, and by using the piercer, a required hole can be drilled in the pedicle of the vertebral arch at a time, thus achieving the function which only can be completed by the cooperation of a hole stabber, a trocar and the piercer before, the hole is formed accurately, the bone loss is small, the operation time is shortened, the operation wound is reduced, and the labor intensity of medical personnel is reduced.

Description

The orthopaedics borer

Technical field

This utility model relates to a kind of medical surgical instrument, the borer that especially a kind of bone surgery uses.

Background technology

Orthopaedics need be holed in pedicle of vertebral arch when breast pedicle of lumbar vertebral arch screw fixing operation, and generally needs perforate vertebra, trocar, borer three to cooperate the boring work of just finishing in the past; With perforate vertebra location, use trocar preboring aperture then earlier, just get out the hole that needs with borer at last.Whole process; More loaded down with trivial details, the apparatus that needs is many, and operating time is long, and healthcare givers's labor intensity is big.

The utility model content

At the problem that above-mentioned prior art exists, this utility model provides that a kind of orthopaedics borer solves that in breast pedicle of lumbar vertebral arch screw fixing operation boring apparatus loaded down with trivial details, that need is many, operating time length, healthcare givers's the big technical problem of labor intensity.

The purpose of this utility model realizes as follows; It relates to drilling rod, connecting rod and handle, the rear end fixed handle of connecting rod, and the drilling rod that connecting rod front end fixed diameter diminishes, the front end of drilling rod has taper bit.Drill bit is rhizoma sparganic cone, four rib vertebral bodys and pentagonal pyramid body.

During use, with the drill bit bore position, while the healthcare givers catches handle to press down the positive and negative turning handle, drill bit and drilling rod just can get out the hole that needs, and the boss that drilling rod and connecting rod junction form plays position-limiting action.

The utlity model has beneficial effect is: use it once to get out the hole that needs in pedicle of vertebral arch, realized that perforate vertebra, trocar, borer three cooperate the function of finishing, opening is accurate, and the loss of bone amount is few, shorten operating time, reduced healthcare givers's labor intensity.
