Abstract
The utility model provides a plug -type hand drill of axial, include draw back plate, jackshaft and with the drill bit that the transmission shaft is connected, be equipped with screw gear and axial gear on the jackshaft, the one side of draw back plate is equipped with the handle, the another side be equipped with the rack just with axial gear engagement, be equipped with on the transmission shaft gear just with screw gear engagement. The utility model discloses plug -type hand drill of axial only need operator's hand handle grip do the push -and -pull campaign can realize the drill bit along axial motion, it is little to occupy the operation space, not influenced by patient's health or operating table facility, and the available health of operator withstands the tail end of transmission shaft, the operation of being convenient for, and simple structure, processing is convenient.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of axial plug-type hand drill.
Background technology
At present, the type of drive of the hand drill that neurosurgery and bone surgery use in bony structure is holed is all that doctor holds turning handle by circular motion drive drill bit rotation, is based on lever principle. Owing to doctor drives turning handle to belong to circular motion, taking up room big, the restriction by patient body and other facilities of operating-table is bigger, therefore, make troubles to operation technique, and the interruption of movement locus that patient can be caused to hold cranium aperture is irregular, even injure surrounding soft tissue. Therefore, clinical needs one drives track amplitude less, is susceptible to the hand drill of context impact.
Utility model content
The purpose of this utility model is in that providing a kind of drives track amplitude less, is susceptible to the axial plug-type hand drill of context impact.
The purpose of this utility model is realized in, a kind of axial plug-type hand drill, including draw back plate, jackshaft and the drill bit that is connected with power transmission shaft, jackshaft is provided with helical gear and axial gears, the one side of draw back plate is provided with handle, another side is provided with tooth bar and engages with axial gears, and power transmission shaft is provided with gear and engages with helical gear. In this technical scheme, owing to helical gear can change the direction of motion of transmission, staff only needs driving handle can engage drive jackshaft with axial gears by tooth bar to rotate, and then is engaged with gear by helical gear and drive power transmission shaft and drill bit axially movable.
For ensureing the convenience that hand drill drives, push-and-pull tooth bar length is 30cm, and width is 3cm.
Above-mentioned jackshaft is arranged on power transmission shaft by bearing.
In order to ensure Stability Analysis of Structures, above-mentioned draw back plate, jackshaft and be arranged in hollow with power transmission shaft.
This utility model has the advantages that
1, the axial plug-type hand drill of this utility model only needs operator to hold handle to do push-and-pull campaign and can realize drill bit axially movable, take operative space little, will not be affected by patient body or operating-table facility, and operator available body withstands the tail end of power transmission shaft, it is simple to implement pressure testing operation.
2, the axial plug-type hand drill of this utility model bores, suitable in neurosurgery operation of opening cranium and orthopaedics, the operation opening bony structure, is used without power supply, can use under the various environment such as field operations and first aid.
3, the axial plug-type hand drill of this utility model need not drive drill bit by circular motion, relatively stable in the process of boring, it is not easy to produce drill bit sliding transfer, not easily surrounding soft tissue is caused damage.
4, the axial plug-type hand drill simple in construction of this utility model, easy to process.

Detailed description of the invention
Embodiment, a kind of axial plug-type hand drill, referring to Fig. 1 and Fig. 2, including draw back plate 1, jackshaft and drill bit 7, drill bit 7 is connected with power transmission shaft 6, and jackshaft is provided with helical gear 4 and axial gears 2, and the one side of draw back plate 1 is provided with handle 8, another side is provided with tooth bar 1-1 and engages with axial gears 2, and power transmission shaft 6 is provided with gear 5 and engages with helical gear 4.
Draw back plate 1 length is 30cm, and width is 3cm. Draw back plate 1, jackshaft and be arranged in hollow with power transmission shaft 6. Jackshaft is arranged in hollow by bearing.
During use, operator driving handle 8, the tooth bar 1-1 on draw back plate 1 engages drive jackshaft and rotates with axial gears 2, and then is engaged with gear 5 by helical gear 4 and drive power transmission shaft 6 and drill bit 7 axially movable. With drill bit 7 direction of motion on the same line, final drive drill bit 7 moves axially draw back plate 1 direction of motion.
The axial plug-type hand drill of this utility model only needs operator to hold handle to do push-and-pull campaign and can realize drill bit axially movable, take operative space little, will not be affected by patient body or operating-table facility, and operator available body withstands the tail end of power transmission shaft, it is simple to operation.
