Abstract

The invention discloses a screw tap specially used in the orthopaedics department. The screw tap comprises the threaded end located at the front end, a connecting rod located in the middle and the handheld portion located at the back end, wherein the threaded end, the connecting rod and the handheld portion are formed integrally, and the threaded end and the connection rod form a rod shape of an integrated structure and are identical in outer diameter. Tapping threads are machined in the outside of the threaded end, a spiral groove is machined in the outside of the connection rod, in a shape for hand holding and is identical to the tapping threads in turning direction, and the middle of the handheld portion is provided with angular bumps perpendicular to the surface of the handheld portion. The screw tap specially used in the orthopaedics department has the advantages that the screw tap is reasonable in structural design, simple and convenient to manufacture and convenient to use, and especially the angular bumps are designed at the connecting position between the connecting rod and the handheld portion, so that friction force is greatly increased, a doctor only needs to turn the handheld portion in the beginning, is directly in contact with the tail portion of the connecting rod in due time and can easily turn the screw tap with a thumb, and the operation time is greatly saved.

Description

A kind of orthopaedics special screw tap

Technical field

The present invention relates to a kind of orthopaedics special screw tap, belong to medical instruments field, be used for auxiliary doctor and use at bone surgery, can make the speed of screw tap when backed off after random is finished in tapping faster, reduce the operating time, reduce Principle of Pain.

Background technology

In the bone surgery fixedly the deck often can use screw tap to carry out tapping; existing screw tap is all in the technical efficient that greatly improved of tapping; can withdraw from very easily but but often ignored when withdrawing from, also can reduce operating time, lower medical and nursing work person's working strength and patient's misery.Traditional medical screw tap no matter tapping how effectively, all the no one improves withdrawing from, must the hand rotation embolus, beginning like this needs to rotate embolus, expends time in very much and energy if rotate embolus always.

Summary of the invention

In order to make the speed of screw tap when backed off after random is finished in tapping faster, reduce the operating time, reduce Principle of Pain, the invention provides a kind of orthopaedics special screw tap.

Purpose of the present invention is come specific implementation by the following technical programs:

A kind of orthopaedics special screw tap, comprise the end of thread that is positioned at front end, the connecting rod in the middle of being positioned at and be positioned at the Handheld Division of rear end, the described end of thread, connecting rod and Handheld Division are one-body molded, it is shaft-like that the end of thread and connecting rod are structure as a whole, and external diameter is identical, the external process of the end of thread has tapping thread, the external process of connecting rod has helicla flute, described helicla flute is processed into the shape that is suitable for holding, described helicla flute is identical with the rotation direction of described tapping thread, is provided with the corner angle with the Handheld Division Surface Vertical at the middle part of described Handheld Division.

Further, described corner angle are positioned at the junction of connecting rod and Handheld Division.

Described Handheld Division is a cross bar, and connecting rod is connected with the center of described cross bar.

The invention has the beneficial effects as follows, reasonable in design, make easy, easy to use, it is fast that its screw tap of combining over solves the operation tapping, speed is slow when having changed tapping end backed off after random, greatly lose time, in the disadvantageous situation of patient, particularly designed corner angle at connecting rod with the part that is connected between the Handheld Division, so greatly increased frictional force, the doctor only need begin to rotate the Handheld Division, just directly contact the connecting rod afterbody to certain the time, just can easily rotate with thumb, greatly saved operating time.

Description of drawings

The below is described in further detail the present invention with embodiment with reference to the accompanying drawings.

Fig. 1 is the structure chart of the described a kind of orthopaedics special screw tap of the embodiment of the invention.

The specific embodiment

As shown in Figure 1, the described a kind of orthopaedics special screw tap of the embodiment of the invention, comprise the end of thread 1 that is positioned at front end, connecting rod 2 in the middle of being positioned at and the Handheld Division 3 that is positioned at the rear end, the described end of thread 1, connecting rod 2 and Handheld Division 3 are one-body molded, it is shaft-like that the end of thread 1 and connecting rod 2 are structure as a whole, and external diameter is identical, the external process of the end of thread 1 has tapping thread, the external process of connecting rod 2 has helicla flute, described helicla flute is processed into the shape that is suitable for holding, described helicla flute is identical with the rotation direction of described tapping thread, is provided with the corner angle with the Handheld Division Surface Vertical at the middle part of described Handheld Division 3.

Further, described corner angle are positioned at the junction of connecting rod 2 and Handheld Division 3.

Described Handheld Division 3 is cross bars, and connecting rod 2 is connected with the center of described cross bar.

The invention has the beneficial effects as follows, reasonable in design, make easy, easy to use, it is fast that its screw tap of combining over solves the operation tapping, speed is slow when having changed tapping end backed off after random, greatly lose time, in the disadvantageous situation of patient, particularly designed corner angle at connecting rod with the part that is connected between the Handheld Division, so greatly increased frictional force, the doctor only need begin to rotate the Handheld Division, just directly contact the connecting rod afterbody to certain the time, just can easily rotate with thumb, greatly saved operating time.
