Abstract
The invention discloses a medical screw tap. The medical screw tap comprises a handle, an arc transition section and a screw tap head, wherein the handle, the arc transition section and the screw tap head are sequentially connected to one another; a clamping plane is arranged on the handle; a plurality of clamping grooves are uniformly distributed in the arc transition section; a threaded groove is formed in the screw tap head; the width of the threaded groove is greater than the thread interval of the screw tap head; and moreover, the screw tap head is provided with a plurality of cutting edges, a plurality of arc connecting surfaces and a plurality of through holes. The medical screw tap is reasonable in design, simple in structure and convenient to use; because a main body is provided with the threaded groove of which the width is greater than the thread interval, crushed bones generated in a tapping process are discharged smoothly, tapping speed is increased, tapping time is greatly shortened, surgery time is also greatly shorted, pain and wound of a patient are relieved, the surgical risk of patients who cannot tolerate long-time surgery are reduced, and the work intensity of surgeons is also reduced.
Description
Technical field
The present invention relates to technical field of medical instruments, particularly a kind of medical screw tap.
Background technology
Orthopedic steel plate internal fixation operation, all needs conventionally with the tapping of screw tap hole, the screw tap of prior art be all generally monofilament apart from screw tap, the broken end of sclerotin producing in tapping process is discharged not smooth, if screwing speed is too fast, is just difficult to guarantee that normal sclerotin is not run bad.Therefore, for guaranteeing that normal sclerotin is not damaged, be, all generally to use hand screw tap hand tapping clinically.Hand tapping, the one, speed is slower, will inevitably cause client's internal fixation operation time lengthening, increase patient's misery and wound, especially for the patient of tolerate surgery for a long time, the having a big risk of its operation, the 2nd, operation technique doctor's working strength is also larger.
Summary of the invention
The deficiency existing for above-mentioned prior art, the object of this invention is to provide a kind of medical screw tap, reasonable in design, simple in structure, easy to use.
A kind of medical screw tap, comprise handle, arc transition section and screw tap head, described handle, arc transition section are connected successively with screw tap head, described handle is provided with clamping plane, in described arc transition section, be evenly distributed with plural clamping groove, described screw tap head is provided with thread groove, and the groove width of described thread groove is greater than the flight lead of described screw tap head, meanwhile, described screw tap head is provided with plural cutting edge, circular arc joint face and through hole.
As preferably, the quantity of described thread groove is 3.
As preferably, the angle of inclination of described thread groove is 130 °.
As preferably, the diameter of described clamping plane is 2.7mm.
As preferably, the diameter of described handle is 6.4mm.
As preferably, the diameter of described thread groove is 12mm.
As preferably, the diameter of described cutting edge is 15mm.
Beneficial effect of the present invention: reasonable in design, simple in structure, easy to use, because main part is provided with the thread groove that is greater than flight lead, the broken end of sclerotin producing in tapping process is discharged unobstructed, screwing speed is accelerated, greatly reduced the tapping time, and then greatly shortened operating time, the misery that alleviates patient is wound very, reduce tolerate surgery patient's operation risk for a long time, be also conducive to alleviate in addition the working strength of operative doctor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
With reference to Fig. 1, this specific embodiment is by the following technical solutions: a kind of medical screw tap, comprise handle 1, arc transition section 4 and screw tap head 5, described handle 1, arc transition section 4 and screw tap head 5 are connected successively, described handle 1 is provided with clamping plane 2, in described arc transition section 4, be evenly distributed with plural clamping groove 3, described screw tap head 5 is provided with thread groove 7, the groove width of described thread groove 7 is greater than the flight lead of described screw tap head, meanwhile, described screw tap head 5 is provided with plural cutting edge 6, circular arc joint face 8 and through hole 9.
Quantity that it should be noted that described thread groove 7 is 3.
Angle of inclination that it should be noted that described thread groove 7 is 130 °.
Diameter that it should be noted that described clamping plane 2 is 2.7mm.
Diameter that it should be noted that described handle 1 is 6.4mm.
Diameter that it should be noted that described thread groove 7 is 12mm.
In addition, the diameter of described cutting edge 6 is 15mm.
This concrete enforcement is reasonable in design, simple in structure, easy to use, because main part is provided with the thread groove that is greater than flight lead, the broken end of sclerotin producing in tapping process is discharged unobstructed, screwing speed is accelerated, greatly reduced the tapping time, and then greatly shortened operating time, the misery that alleviates patient is wound very, reduce tolerate surgery patient's operation risk for a long time, be also conducive to alleviate in addition the working strength of operative doctor.
The above is only better embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
