Description
Technical field
This utility model relates to a kind of orthopedic tap.
Background technology
Along with the development and progress of science and technology, orthopaedics and tranmstology has had the biggest progress in terms of diagnosis, treatment.The foundation of hands surgery and development, make the Diagnosis Technique of hand injury rapidly be universal and improve；Extensively carrying out of microsurgery, makes many toes dissociate Hand Reconstruction, the coincideing and loosen of nerve tract, and coincideing between the small artery of 0.2mm is the most no longer mythical；The diseases such as new art formula treatment skoliosis, cervical spondylosis and cervical spinal stenosis are used all to achieve preferable orthopaedics and tranmstology effect；The various effective art formula that arthritic is taked so that the patient liied in bed for many years stands up from newly；Treatment to malignant bone tumor develops into comprehensive treatment from single amputation, improves cure rate and the survival rate of operation；The clinical practice of knee arthroscope, not only solves some difficult arthropathic diagnosis, and achieves diagnosis and treatment synchronization is carried out；Development along with material science so that the fracture of some complexity the most also can manage it internal fixation treatment；Artificial joint, the function of artificial vertebral body and performance are the most perfect.In a word, the development of the development of orthopaedics and tranmstology and preclinical medicine, particularly experimental medicine and material science is undivided.
Along with epoch and the change of society, injury of orthopaedics department spectrum has had obvious change, such as, the diseases such as tuberculosis of bone and joint, osteomyelitis, poliomyelitis significantly reduce, the wound showed increased that vehicle accident causes, population aging, fracture, orthopaedics and tranmstology arthrosis that senile osteoporosis causes increase, the impact of environmental factors, bone tumor, rheumatoid arthritis increase etc. accordingly.
At present in the middle of some bone surgeries, need to use steel plate to be fixed, it is therefore desirable to screw tap carries out auger shell pit, existing orthopaedics screw tap inconvenient operation, easily causes stripped thread during boring.
Utility model content
It is effective that the technical problems to be solved in the utility model is to provide a kind of tapping, it is possible to is effectively prevented stripped thread, facilitates the orthopedic tap of the keyhole degree of depth.
For solving the problems referred to above, this utility model adopts the following technical scheme that a kind of orthopedic tap, including shaft, threaded portion, drill bit and drill sleeve, described threaded portion and drill bit are located at shaft lower end, the one-body molded setting of described shaft and threaded portion, described drill bit removably connects with threaded portion, described drill sleeve is located at outside threaded portion, described drill sleeve is connected with threaded portion, described shaft top is provided with hands handle, the T-shaped setting of described handle, bar shaped hole slot it is provided with on described drill sleeve, it is provided with ring for fixing on the drill sleeve at described bar shaped hole slot two ends, helicla flute and ridge it is provided with on described drill bit, described ridge is distributed twist.
As preferably, described shaft is fixing with handle to be connected, and keeps handle Stability Analysis of Structures in use.
As preferably, described drill sleeve top is provided with pad, when pad can keep drill sleeve to rotate on the net, contacts with shaft, it is to avoid cause drill sleeve to damage.
As preferably, curved setting bottom described drill sleeve, it is possible to when being maintained at boring, when drill sleeve and Body contact, do not result in scuffing.
As preferably, described shaft diameter is more than 2cm.
The beneficial effects of the utility model are: have helicla flute and ridge on the drill bit of setting so that ridge is when auger shell pit, and chip can be discharged from screw thread slotted eye, keep tapping effective, it is possible to be effectively prevented stripped thread；The drill sleeve arranged can be in rotary moving on threaded portion, thus regulates bit depth, facilitates the keyhole degree of depth；The impurity that the bar shaped hole slot arranged enables in drill sleeve after a long time use is discharged from bar shaped hole slot, does not interferes with the in rotary moving of drill sleeve.
Accompanying drawing explanation
Fig. 1 is the structure chart of a kind of orthopedic tap of this utility model, and Fig. 2 is the drill bit structure figure of a kind of orthopedic tap of this utility model.
Detailed description of the invention
As shown in Figure 1, a kind of orthopedic tap, including shaft 1, threaded portion 2, drill bit 3 and drill sleeve 4, described threaded portion 2 and drill bit 3 are located at shaft 1 lower end, the one-body molded setting of described shaft 1 and threaded portion 2, described drill bit 3 removably connects with threaded portion 2, described drill sleeve 4 is located at outside threaded portion 2, described drill sleeve 4 is threadeded with threaded portion 2, described shaft 1 top is provided with handle 5, the described T-shaped setting of handle 5, it is provided with bar shaped hole slot 6 on described drill sleeve 4, it is provided with ring for fixing 7 on the drill sleeve 4 at described bar shaped hole slot 6 two ends, helicla flute 8 and ridge 9 it is provided with on described drill bit 3, described ridge 9 is distributed twist.
Described shaft 1 is fixing with handle 5 to be connected.
Described drill sleeve 4 top is provided with pad 10.
Curved setting bottom described drill sleeve 4.
Described shaft 1 diameter is more than 2cm.
The beneficial effects of the utility model are: have helicla flute and ridge on the drill bit of setting so that ridge is when auger shell pit, and chip can be discharged from screw thread slotted eye, keep tapping effective, it is possible to be effectively prevented stripped thread；The drill sleeve arranged can be in rotary moving on threaded portion, thus regulates bit depth, facilitates the keyhole degree of depth；The impurity that the bar shaped hole slot arranged enables in drill sleeve after a long time use is discharged from bar shaped hole slot, does not interferes with the in rotary moving of drill sleeve.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model is not limited thereto, any change expected without creative work or replacement, all should contain within protection domain of the present utility model.
