Description
Technical field
This utility model relates to technical field of medical instruments, relates in particular to a kind of orthopaedics nail taking-out forceps.
Background technology
The orthopedist once ran into screw and screwdriver slide fastener phenomenon in the hospital in operation, particularly in the screw that runs into the steel difference and screw reason such as get rusty in vivo, caused screw in a dilemma; Since this problem screw nail tail and steel plate very near, and the nail tail is circle, traditional like this hand vice contact stud tail is 2 points; Unload pine and waste time and energy because of contact area causes tightening, and 2 be prone to slide, more when getting internal fixation see more; When being exactly the taking-up of hollow nail of fracture of femoral neck in addition; Because of the self-locking action of hollow nail, add that the preceding thick back of hollow nail is thin, it is the equal of to enlarge a bone hole with following closely the silk that makes head that rotation draws off hollow nail; Resistance is quite powerful, even causes orthopedist's hands mill to bubble hemorrhage.
The utility model content
The technical problem that this utility model solved is to provide a kind of orthopaedics nail taking-out forceps, and fully the contact area of increase and screw is prevented sliding stop, is convenient to medical personnel and in time takes out screw, raises the efficiency, and has reduced the patient suffering.
The technical scheme of the technical problem that this utility model solved is: a kind of orthopaedics nail taking-out forceps; Comprise through bearing pin hinged first caliper and second caliper; The said first caliper front end is provided with first binding clip; The said second caliper front end is provided with second binding clip, and the clamping face of said first binding clip and second binding clip is equipped with the horizontally extending cut of file, is provided with groove between the cut of file of the clamping face side of said first binding clip; The bearing of trend of the said groove and the cut of file is perpendicular, and said groove extends to the top of said first binding clip.
As optimized technical scheme, the lozenges side of first binding clip is provided with wedge-shaped slot, and the bearing of trend of said wedge-shaped slot is directed to said bearing pin.
As optimized technical scheme, second binding clip is provided with from first hole of the second binding clip top end opening, and first hole is provided with spiral alveolar perpendicular to the vertical end face of described second binding clip in said first hole.
As optimized technical scheme, the lozenges side of second binding clip is provided with perpendicular to the second axial hole of said first hole, is provided with spiral alveolar in said second hole.
As optimized technical scheme, be provided with the elasticity that said first caliper and second caliper are flicked mutually between first caliper and second caliper and strut steel disc.
Owing to adopted a kind of orthopaedics nail taking-out forceps of technique scheme, be provided with groove in the clamping face side, so just there are two traditional point gearing to become three point gearing, fully increased the contact point with the nail tail of screw, prevented slip, be convenient in time take out screw.
Because second binding clip is provided with first hole and second hole, and between first caliper and second caliper, is provided with elasticity and struts steel disc, can utilize the nail tail medicated cap of top and the flexible clamp screws of lateral hole and take out screw, use flexibly, be convenient to operate.
Description of drawings
Fig. 1 is the structural representation of this utility model orthopaedics nail taking-out forceps;
Fig. 2 is the structural representation of groove of first binding clip of this utility model orthopaedics nail taking-out forceps;
Among the figure: 1. first caliper, 2. second caliper, 3. bearing pin, 4. first binding clip, 5. second binding clip, 6. groove, 7. wedge-shaped slot, 8. first hole, 9. second hole, 10. elasticity struts steel disc, 11. cut of files.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, further set forth this utility model, should be understood that these embodiment only be used to this utility model is described and be not used in the restriction this utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to this utility model after the content of having read this utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Shown in Fig. 1, Fig. 2 were common, a kind of orthopaedics nail taking-out forceps comprised that first caliper 1, second caliper 2 and bearing pin 3 constitute; The folding of first caliper 1 and second caliper 2 is hinged through bearing pin 3, and the flexible steel disc 10 that struts makes first caliper 1 and the 2 automatic foldings of second caliper, is convenient to manually press from both sides tweezer; First caliper, 1 front end is provided with the clamping face that first binding clip, 4, the second calipers, 2 front ends are provided with second binding clip, 5, the first binding clips 4 and second binding clip 5 and is provided with the cut of file 11; Prevent the landing of gripping object; The top end that the lozenges side that the clamping face side of first binding clip 4 is provided with groove 6, the first binding clips 4 is provided with wedge-shaped slot 7, the second binding clips 5 is provided with first hole 8 of vertical top end face direction; The lozenges side of second binding clip 5 is provided with perpendicular to being equipped with spiral alveolar in axial second hole, 9, the first holes 8 of first hole 8 with in second hole 9.
Owing to adopted a kind of orthopaedics nail taking-out forceps of technique scheme, be provided with groove 6 in the clamping face side, so just there are two traditional point gearing to become three point gearing; Fully increased contact point with the nail tail of screw; Prevented slip, be convenient in time take out screw, because second binding clip 5 is provided with first hole 8 and second hole 9; And between first caliper 1 and second caliper 2, be provided with elasticity and strut steel disc 10; Can utilize the nail tail medicated cap of top and the flexible clamp screws of lateral hole and take out screw, use flexibly, be convenient to operation.This utility model reasonable in design, fully the contact area of increase and screw is prevented sliding stop, is convenient to medical personnel and in time takes out screw, raises the efficiency, and has reduced the patient suffering.
More than show and described the advantage of ultimate principle, principal character and this utility model of this utility model.The technical staff of the industry should understand; This utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the description that this utility model just is described; Under the prerequisite that does not break away from this utility model spirit and scope, this utility model also has various changes and modifications, and these variations and improvement all fall in this utility model scope that requires protection.This utility model requires protection domain to be defined by appending claims and equivalent thereof.
All are from the design of this utility model, and the reconfiguration of having done without creative work all drops within this utility model protection domain.
