Abstract
The utility model relates to a medical device, in particular to a pre-fixed orthopedics internal fixation bone fracture plate and a positioning steel needle. The bone fracture plate comprises an orthopedic internal fixation bone fracture plate with screw elliptical holes at intervals and a matched screw, and is provided with a positioning steel needle which is formed by connecting a needle handle, a needle point and a screw head into a whole; a plurality of steel needle round holes and steel needle elliptical holes are orderly drilled on the orthopaedics internal fixation bone fracture plate with screw elliptical holes at intervals. The utility model has the advantages of can with orthopedics internal fixation coaptation board pre-fixation on the skeleton of suffering from the limb, need not to use holding forceps, bone surgery convenient operation, can not cause the obstacle to follow-up operation, be suitable for orthopedics medical institution to use.
Description
One, technical field
This utility model relates to a kind of medical treatment device, and especially a kind of orthopaedics internal fixation blade plate and location draw point of pre-fixing is suitable for orthopaedics medical treatment and uses.
Two, background technology
Existing orthopaedics internal fixation blade plate is made of the orthopaedics internal fixation blade plate and the supporting screw that have the screw elliptical aperture at interval, during with this device immobilized patients bone, need orthopaedics internal fixation blade plate to be fixed on the skeleton of suffering from limb with bone holding forceps, therefore could fix after should taking to peel off the measure of periosteum or skeleton surrounding soft tissue, there is following deficiency in it: the one, and often cause bone holding forceps to be difficult to clamping for the fracture of near articulation etc., make troubles to bone surgery; The 2nd, bone holding forceps take up room greatly, appear in the district in limited operation, usually can cause obstacle to the subsequent procedures operation.
Three, summary of the invention
The purpose of this utility model provides a kind of orthopaedics internal fixation blade plate and location draw point of pre-fixing, and it can solve the deficiencies in the prior art.
For achieving the above object, the scheme of this utility model design comprises orthopaedics internal fixation blade plate and the supporting screw composition that has the screw elliptical aperture at interval, is provided with the location draw point that is joined together by needle handle, needle point, screw terminal; On the orthopaedics internal fixation blade plate that has the screw elliptical aperture at interval, be drilled with some draw point circular holes and draw point elliptical aperture in an orderly manner.
This utility model is because be provided with the location draw point that is joined together by needle handle, needle point, screw terminal and be drilled with some draw point circular holes and draw point elliptical aperture in an orderly manner on orthopaedics internal fixation blade plate, orthopaedics internal fixation blade plate can be pre-fixed on the skeleton of suffering from limb, need not to use bone holding forceps just can reach orthopaedics internal fixation blade plate is fixed on purpose on the skeleton of suffering from limb, so bone surgery is easy to operate, can not cause obstacle to the subsequent procedures operation; In addition owing to not changing the basic structure of former orthopaedics internal fixation blade plate and supporting screw, so do not influence the inherent performance of original device at all.
Four, description of drawings
Concrete structure of the present utility model is provided by the following drawings.
Fig. 1 is according to a kind of orthopaedics internal fixation blade plate front view that pre-fixes that the utility model proposes.
Fig. 2 is according to a kind of location draw point front view that the utility model proposes.
Fig. 3 can pre-fix orthopaedics internal fixation blade plate and location draw point cooperation sketch map.
Each sign expression in the accompanying drawing:
1. orthopaedics internal fixation blade plate 2. screw elliptical apertures 3. draw point circular holes 4. draw point elliptical apertures 5. needle handles 6. needle points 7. screw terminals
Below in conjunction with accompanying drawing this utility model is described in further detail.
Five, the specific embodiment
As shown in Figure 1, the scheme of this utility model design comprises orthopaedics internal fixation blade plate 1 and the supporting screw composition that has screw elliptical aperture 2 at interval, is provided with the location draw point that is joined together by needle handle 5, needle point 6, screw terminal 7; On the orthopaedics internal fixation blade plate 1 that has screw elliptical aperture 2 at interval, be drilled with some draw point circular holes 3 and draw point elliptical aperture 4 in an orderly manner.
The needle point 6 of described location draw point and screw terminal 7 diameters are less than needle handle 5 diameters.
Described needle point 6 and screw terminal 7 length are 0.2～2 times of needle handle 5 length.
The minor axis of the diameter of described draw point circular hole 3 and draw point elliptical aperture 4 is slightly larger than needle point 6 and screw terminal 7 diameters.
