Abstract
The utility model discloses a craniotomy drilling tool, which comprises a transmission. A drilling rod, on which a drilling chuck and a drilling bit are mounted, is arranged at the lower part of the transmission; the upper end of the drilling rod is arranged in the transmission and provided with a driven gear. A first rotation shaft and a second rotation shaft are arranged on the two side walls of the transmission; a first bevel gear which is meshed with the driven gear is arranged at one end of the first rotation shaft in the transmission and a second bevel gear which is meshed with the driven gear is arranged at one end of the second rotation shaft in the transmission. When in use, firstly the first bevel gear is turned around by a handle to drive the driven gear which then drives the drilling bit to rotate in a rapid speed, thus the patient suffers less from bleeding and pain; when the skull is drilled thoroughly approximately, the handle is mounted on the second rotation shaft and rotated slowly, which prevents the craniotomy tissue damaging due to the rapid speed, thus ensuring the life security of the patient and improving the operation effect.
Description
Technical field
This utility model relates to a kind of orthopaedics operation of opening cranium sphenotresia apparatus, relates to a kind of drill for craniotomy tool specifically, belongs to medical device technology neck city.
Background technology
Drill for craniotomy is the clinical indispensable apparatus of orthopaedics, every routine operation of opening cranium must be bored several bone holes earlier on skull, operator requires the cranium brill will sterilize easy to use, be perfectly safe when boring cranium, present general drill for craniotomy can be divided into three kinds with power mode in the ability city, be bitbrace, pneumatic drill and electric drill, wherein bore the most commonly used with the hand-rail type cranium again, its drill bit of the tired brill of traditional hand-rail type is 1: 1 with the ratio of the rotating speed of wind, the speed of boring cranium is slow, during Operation Fee, effort, patient's amount of bleeding is increased.Though electric drill and pneumatic drill have improved brill cranium speed, complex structure involves great expense, need alternating current power supply or high pressure nitrogen as power source, both use also safety inadequately of inconvenience, adopt in addition that to prepare link before the art of electric drill or pneumatic drill complicated, also pollute easily.
The utility model content
The technical problems to be solved in the utility model provides a kind of can the raising and bores cranium speed, can guarantee patient safety again, improves the drill for craniotomy tool of surgical effect.
For addressing the above problem, this utility model by the following technical solutions:
A kind of drill for craniotomy tool, comprise a gearbox body, bottom at gearbox body is provided with drilling rod, drill chuck and drill bit are installed on drilling rod, described drilling rod upper end is positioned at gearbox body and driven gear is installed, on the shell wall of the both sides of gearbox body, be separately installed with first turning cylinder and second turning cylinder, an end that is positioned at gearbox body at first turning cylinder is equipped with first bevel gear that is meshed with driven gear, and an end that is positioned at gearbox body on second turning cylinder is equipped with second bevel gear that is meshed with driven gear.
Below be the utility model for further improvement of these options:
The rotating ratio of described first bevel gear and driven gear is 1: 2.
As further improvement:
The rotating ratio of described second bevel gear and driven gear is 1: 1.
Further improve:
Be rotationally connected by bearing respectively between the shell wall of drilling rod, first turning cylinder and second turning cylinder and gearbox body.
Further improve:
Be provided with general crank in the outside of first turning cylinder, be provided with handle on gearbox body top.
This utility model adopts such scheme, when bringing into use, at first rotate the first bevel gear driving driven gear and drive the drill bit rotation, carry out the drill for craniotomy hole, because the rotating ratio of first bevel gear and driven gear is 1: 2 by crank, at this moment, the rotating speed of drill bit is very fast, can creep into fast, has reduced patient's amount of bleeding, and pain, in the time approximately will boring, crank is installed on second turning cylinder, slowly shake crank, because the rotating ratio of second bevel gear and driven gear is 1: 1, at this moment, the speed of drill bit is slower, has prevented to cause owing to excessive velocities the injury of intracranial tissue, guarantee patient's life security, improved surgical effect.
The utility model is described in further detail below in conjunction with drawings and Examples:
Description of drawings
Accompanying drawing is the structural representation of this utility model embodiment.
The specific embodiment
Embodiment, as shown in the figure, a kind of drill for craniotomy tool, comprise a gearbox body 1, be provided with handle 2 on the top of gearbox body 1, be provided with drilling rod 3 in the bottom of gearbox body 1, drill chuck 8 and drill bit 9 are installed on drilling rod 3, described drilling rod 3 upper ends are positioned at gearbox body 1 and driven gear 4 are installed, be rotationally connected by bearing between the shell wall of drilling rod 3 and gearbox body 1, on the shell wall of the both sides of gearbox body 1, install respectively by bearing and be rotatably connected to first turning cylinder 61 and second turning cylinder 6, an end that is positioned at gearbox body 1 at first turning cylinder 61 is equipped with first bevel gear 51 that is meshed with driven gear 4, first bevel gear 51 is 1: 2 with the rotating ratio of driven gear 4, an end that is positioned at gearbox body 1 on second turning cylinder 6 is equipped with second bevel gear 5 that is meshed with driven gear 4, second bevel gear 5 is 1: 1 with the rotating ratio of driven gear 4, is provided with general crank 7 in the outside of first turning cylinder 61.
When bringing into use, at first rotate first bevel gear 51 and drive 9 rotations of driven gear 4 drive drill bits by crank 7, carry out the drill for craniotomy hole, because first bevel gear 51 is 1: 2 with the rotating ratio of driven gear 4, at this moment, the rotating speed of drill bit 9 is very fast, can creep into fast, reduced patient's amount of bleeding, and pain, in the time approximately will boring, crank 7 is installed on second turning cylinder 6, slowly shake crank 7, because the rotating ratio of second bevel gear 5 and driven gear 4 is 1: 1, at this moment, the speed of drill bit 9 is slower, prevented to cause the injury of intracranial tissue, guaranteed patient's life security, improved surgical effect owing to excessive velocities.
