Abstract
The invention discloses a kind of orthopaedics centralization bit guide, including: connecting rod, fairlead and jaw；The outer wall of described fairlead upper end is connected fixing with described connecting rod, and the end face of fairlead lower end is provided with anti-skidding sawtooth；Described jaw includes sleeve, stop screw and a pair arc elastic sheet metal, and two panels arc elastic sheet metal is fixed on sleeve lower end, and two panels arc elastic sheet metal is symmetrically set；Described sleeve is slidably enclosed within fairlead, and sleeve is fixed with fairlead by stop screw.By the way, drill bit can be controlled to hit exactly at skeleton pulp cavity by the present invention, it is ensured that the maximum holding dynamics of screw, and decreases surgical injury, shortens operating time, reduces operative hemorrhage.
Description
Technical field
The present invention relates to medical treatment drilling instrument field, particularly relate to a kind of orthopaedics centralization bit guide.
Background technology
Requisite the same instrument when guider is Following Orthopaedic Procedures, common guider is only in fairlead remote design
Sawtooth, clinician is when using common guider to hole at bone surface, and skidding often occurs in drill bit, and causes boring to be lost
Losing, clinician it is frequently necessary to repeated multiple times punching could get out required screw hole at smooth bone surface.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of orthopaedics centralization bit guide, it is possible to by drill bit control
Hit exactly at skeleton pulp cavity, it is ensured that the maximum holding dynamics of screw, and decrease surgical injury, shorten operating time, reduce
Operative hemorrhage.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of orthopaedics centralization drill bit
Guider, including: connecting rod, fairlead and jaw；The outer wall of described fairlead upper end is connected fixing with described connecting rod, guides
The end face of set lower end is provided with anti-skidding sawtooth；Described jaw includes sleeve, stop screw and a pair arc elastic sheet metal, two panels
Arc elastic sheet metal is fixed on sleeve lower end, and two panels arc elastic sheet metal is symmetrically set；Described sleeve is slidably
Being enclosed within fairlead, sleeve is fixed with fairlead by stop screw.
Preferably, described sleeve having along sleeve axis direction bar hole, described fairlead sidewall is provided with spacing
The screw hole that screw matches, described stop screw one end is through bar hole and inserts in screw hole.
Preferably, described guiding is cased with two, is separately fixed at connecting rod two ends.
The invention has the beneficial effects as follows: drill bit can be controlled to hit exactly at skeleton pulp cavity by the present invention, it is ensured that screw is
Hold greatly dynamics, and decrease surgical injury, shorten operating time, reduce operative hemorrhage.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of orthopaedics centralization bit guide one preferred embodiment of the present invention.
In accompanying drawing, the labelling of each parts is as follows: 1, connecting rod；2, fairlead；3, sleeve；4, arc elastic sheet metal；5, limit
Position screw.
Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of orthopaedics centralization bit guide, including: connecting rod 1, fairlead 2 and jaw, fairlead 2 has two, solid respectively
It is scheduled on connecting rod 1 two ends；The outer wall of described fairlead 2 upper end is connected fixing with described connecting rod, on the end face of fairlead lower end
It is provided with anti-skidding sawtooth；Described jaw includes sleeve 3, stop screw 5 and a pair arc elastic sheet metal 4, two panels arc elastic gold
Belong to sheet 4 and be fixed on sleeve 3 lower end symmetrically, between two panels arc elastic sheet metal 4, form circular clamp mouth；Described sleeve 3
Slidably being enclosed within fairlead, sleeve has along sleeve axis direction bar hole, described fairlead sidewall is provided with and limits
The screw hole that position screw matches, described stop screw 5 one end is through bar hole and inserts in screw hole.
The present invention adds sleeved at the periphery of original fairlead, and hub distal end design arc elastic sheet metal, sleeve is near
Hold equipped with stop screw, to adapt to human body from femur, humerus, tibia, different straight to clavicle, ulna and radius, metacarpal-phalangeal, sole of the foot phalanx etc.
The boring demand of footpath skeleton, arc elastic sheet metal has elastical retraction performance, can be with stuck fast skeleton both sides, no matter drill bit
How direction offsets, and drill bit is controlled to hit exactly at skeleton pulp cavity by centralization guider all the time, it is ensured that the maximum hold of screw
Degree, and decrease surgical injury, shorten operating time, reduce operative hemorrhage.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this
The equivalent structure that bright description and accompanying drawing content are made, or directly or indirectly it is used in other relevant technical fields, the most in like manner
It is included in the scope of patent protection of the present invention.
