Description
Technical field
The invention belongs to technical field of medical instruments, belong to orthopedic instrument technical field further, be specifically related to a kind of use
In fracture merges fixation procedure, during especially fracture of the carpal bone merges fixation procedure, carry out the reduction of the fracture for installing fusion device,
Fixing and auxiliary bore hole carpal bone four foot fusion device positions and drilling aid.
Background technology
Fracture is that human body sustains an injury frequent situation, and it is the most frequently used medical means that the reduction of the fracture is fixed.Wrist
Being mankind's functional parts the most flexibly, carpal bone is to be combined into by the bone piece of polylith different structure, is that structure is complicated.Once it is subject to
To injury, its replacement and fixation is more than the reduction of the fracture difficulty at other positions.The reset of prior art typically use Kirschner wire,
The replacement and fixation fracture of the carpal bone positions such as fixation steel plate, do not have pressurization owing to these apparatuses are fixing to intercarpal joints position,
The postoperative extenal fixation needing the long period, exerts a certain influence to the functional rehabilitation of patient, i.e. can recover slow.And steel
Plate bolt is fixed needs and is punched on less carpal bone, operation complexity, increases operation wound, affects function of joint, and postoperative can
The complication such as pain and infection can occur, totally unfavorable to carpal recovery.Melted to this end, the present inventor once develops multiple carpal bone
Clutch also achieves national patent, this technology should be replaced with traditional fixation steel plate, reached the good reduction of the fracture merge
Purpose and therapeutic effect.But, this fusion device needs location and boring in a pre-installation, owing to carpal bone bone piece is little, during boring
Easily injuring surrounding soft tissue, the impact of the factors such as the multi-dimensional nature that bone piece coordinates, after causing realizing the reduction of the fracture with traditional apparatus
Being accurately positioned and holing the most highly difficult of fixing hole, have impact on the using effect of carpal bone fusion device.Therefore, develop one and melt
The supporting fusion stationary positioned device of clutch is very important, and is the best way overcoming prior art defect.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, easy and simple to handle, contribute to the reduction of the fracture, registration, bore
Hole coordinates carpal bone four foot fusion device location and drilling aid accurately with fusion device.
The purpose of the present invention is achieved in that, including drill bushing seat, drill bushing and extension rod, described drill bushing seat connects prolongation
Bar, uniform on described drill bushing seat arrange two drill bushing, drill bushing front end is provided with anti-skidding thorn.
The present invention uses engraved structure, has both been easy to location, is easy to again observe boring.The present invention is as possessing identical fixing foot
Fusion device kit, it is not necessary to measure and can meet the needs of the installing hole being accurately positioned and drilling through fusion device.Ensure that wrist
Bone fusion device is accurately installed and is put in place, it is to avoid the reset of the damage of surrounding soft tissue, beneficially patients with fractures, fixing and function is extensive
Multiple, it is a kind of very useful orthopaedics therapy medical apparatus and instruments.

Fig. 1 is the stereochemical structure relation schematic diagram of the present invention；
Fig. 2 is the left view of Fig. 1；
Fig. 3 is the right view of Fig. 1；
Fig. 4 is another embodiment structural relation schematic diagram of the present invention.
In figure: 1-drill bushing seat, 11-observation port, 2-drill bushing, the anti-skidding thorn of 21-, 22-leads boring, 3-extension rod, 4-handle.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings, but is any limitation as the present invention never in any form, based on
Present invention teach that any conversion made, each fall within scope.
As shown in Fig. 1 ~ 3, the present invention includes that drill bushing seat 1, drill bushing 2 and extension rod 3, described drill bushing seat 1 connect extension rod
3, uniform on described drill bushing seat 1 arrange two drill bushing 2, drill bushing 2 front end are provided with anti-skidding thorn 21.
Described drill bushing seat 1 rear end arranges extension rod 3, described extension rod 3 front end axially and its main part be 10 ~
30 ° of angles.So as the angle adjusted between handle 4 and drill bushing seat 1 working face.Want with the operation in boring procedure to adapt to fix
Ask.
Described drill bushing seat 1 is in engraved structure, and corner is symmetrical arranged drill bushing 2, and the center portion thereof position arranges observation port 11, convenient
Observation during use, contributes to being accurately positioned.Described drill bushing seat 1 uses tight fit structure with drill bushing 2, can take interference
Fit structure or employing rearward end welding manner all can realize the purpose of the present invention.
The described longitudinally disposed through-hole structure of drill bushing 2 lead boring 22.
Described anti-skidding thorn 21 is " V " structure, and angular aperture is 45 ~ 75 °, and optimal way is 50 ~ 60 °.
Described anti-skidding thorn 21 is the zigzag structure along drill bushing 2 front end circumference uniform distribution.
A length of 10 ~ 30 mm of described drill bushing 2, optimal way is 12 ~ 20 mm.
The described neighbor distance between drill bushing 2 is 5 ~ 20mm, and optimal way is 8 ~ 14mm.
Described extension rod 3 is threaded connection mode and is connected with drill bushing seat 1, and extension rod 3 rear end arranges handle 4.Extend
Bar 3 can also be connected by clamping or fixed form with drill bushing seat 1, does not affect the realization of the object of the invention.
