Abstract
The utility model discloses an orthopedic drill and relates to a drilling rod, a connecting rod and a handle, wherein the back end of the connecting rod is fixed with the handle, the front end of the connecting rod is fixed with the drilling rod with reduced diameter, and a conical drill bit is arranged at the front end of the drilling rod. The orthopedic drill is used for orthopedic thoracic and lumbar vertebral pedicle screw fixation operation, and the use of the orthopedic drill can drill a required hole on a vertebral pedicle, realize the functions which are completed by a hole-opening cone, a sheath needle and a drill through matching, lead the hole opening to be accurate and the loss of bone mass to be less, shorten the operation time and reduce the labor intensity of medical staffs.
Description
Technical field:
This utility model relates to a kind of medical operating utensil, the borer that especially a kind of orthopaedics uses.
Background technology:
Orthopaedics is when breast pedicle of lumbar vertebral arch screw fixing operation, need on pedicle of vertebral arch, hole, can finish boring work and generally need perforate awl, trocar, borer three to cooperate just in the past: with perforate awl location, use trocar preboring aperture then earlier, just get out the hole that needs at last with borer.Whole process is more loaded down with trivial details, and the apparatus that needs is many, and operating time is long, and healthcare givers's labor intensity is big.
Summary of the invention:
The purpose of this utility model provides a kind of orthopaedics borer, and solution boring in breast pedicle of lumbar vertebral arch screw fixing operation apparatus loaded down with trivial details, that need is many, operating time long, 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 the rectangular pyramid body.
During use, with the drill bit bore position, while the healthcare givers catches handle to press down forward and reverse 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 beneficial effect that the utlity model has is: use it can once get out the hole that needs on pedicle of vertebral arch, realized that perforate awl, 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.
Description of drawings:
Accompanying drawing is the structural representation of this utility model orthopaedics borer.
The specific embodiment:
With reference to accompanying drawing, it relates to drilling rod 3, connecting rod 2 and handle 1, the rear end fixed handle 1 of connecting rod 2, and the drilling rod 3 that connecting rod 2 front end fixed diameters diminish, the front end of drilling rod 3 has taper bit 4, and drill bit 4 is the rectangular pyramid body.
