Abstract
The utility model relates to a medical screw tap which is realized by making improvements on the basis of the screw taps in the prior art. The utility model comprises a head, a main body and a tail and is characterized in that the main body is provided with a large spiral flute which is larger than the wire internal. The utility model has the advantages of a quite reasonable design, a simple structure and convenient use. Besides, as the main body is provided with the large spiral flute which is larger than the wire internal, the bone slag produced in the tapping course may be discharged smoothly, the utility model may be applied to an electric tapping to speed up the tapping, to shorten the tapping time and further to shorten the times of operations, and to alleviate the pains of patients and the risks in operations made to patients who could not bear operations for a long time. Additionally, the utility model is also beneficial to the work intensity of doctors performing the operations.
Description
Technical field: this utility model relates to a kind of medical screw tap.
Background technology: the orthopedic steel plate internal fixation operation all needs to use the screw tap drilling and tapping usually.The screw tap of prior art generally all be monofilament apart from screw tap, the broken foam of the sclerotin that is produced in tapping process is discharged not smooth, if the tapping excessive velocities just is difficult to guarantee that normal sclerotin is not damaged.Therefore, be not damaged, generally all be to use hand screw tap hand tapping clinically for guaranteeing normal sclerotin.Hand tapping, the one, speed is slower, will inevitably cause orthopaedics internal fixation operation time lengthening, increases 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 bigger.
Technology contents: the purpose of this utility model provides a kind of novel medical screw tap, in order to overcome the above-mentioned drawback of existing in prior technology effectively.This utility model is to improve realization on the basis of existing technology, and it comprises head, main part and afterbody, it is characterized in that main part is provided with the king bolt groove greater than its flight lead.During use, screw tap of the present utility model is installed on the electric drill that matches with it, can be in order to electric threading.
This utility model design is more reasonable, simple in structure, easy to use, because main part is provided with the king bolt groove greater than its flight lead, the broken foam of the sclerotin that is produced in the tapping process is discharged unobstructed, can be used for electric threading, tapping is speeded up, significantly reduce the tapping time, and then shorten operating time greatly, alleviate patient's misery and wound, reduce the patient's of tolerate surgery operation risk for a long time; Also help alleviating the working strength of operative doctor in addition.
Description of drawings: accompanying drawing is a front view of the present utility model.
The specific embodiment: accompanying drawing has provided an embodiment of the present utility model, with reference to the accompanying drawings shown in, it is made of head 1, main part 2 and afterbody 4, its main part 2 is provided with the king bolt groove 3 greater than its flight lead.
For this utility model and general common electric drill can both be equipped with, said afterbody 4 is provided with the hitching post 5 that afterbody and common electric drill can both be equipped with.
Claims (2)
1: a kind of medical screw tap, comprise that head (1), main part (2) and afterbody (4) constitute, its main part (2) is provided with the king bolt groove (3) greater than its flight lead.
2: medical screw tap according to claim 1 is characterized in that said afterbody (4) is provided with a hitching post (5) that afterbody (4) and common electric drill can both be equipped with.
