Specific embodiment
Below by specific embodiment, the technical solution of the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of Novel cranial drill, including drillstock 1 and the drill bit 2 for being mounted on 1 front end of drillstock, drillstock 1
Including shell, above equipment is common equipment for person of ordinary skill in the field, does not need to pay creativeness
Labour, the utility model mainly increase chilled water unit and negative suction system to the improvement of traditional cranial drill.
The chilled water unit includes the cooling-water duct 3 opened up along the central axis of drill bit 2, across the cooling of the shell
The rear end of water pipe 4 and the micro pump 5 that 1 rear end of drillstock is arranged in, cooling-water duct 3 connects cooling water pipe 4 by rotary joint 6
Front end, 4 rear end of cooling water pipe pass through the external cooling water source of micro pump 5；In use process, cooling water source successively passes through Miniature water
After pump 5, cooling water pipe 4 and cooling-water duct 3, enter in drilling from the front end center of drill bit 2, from the outside uniform decrease in temperature in center,
Cooling effect is more preferable；It is to relatively rotate due to the rotation of drill bit 2, between cooling-water duct 3 and cooling water pipe 4, in order to guarantee
Rotate the sealed set of junction rotary joint 6.
The negative suction system includes adjustment frame 8, suction channel 4 and the annular bleed that 4 front end of suction channel is arranged in
First 7, adjustment frame 8 is arranged in the shell, for installing suction channel 4；Annular bleed head 7 is looped around 2 outside of drill bit, so as to
Suction cooling water and the bone mud that is mixed to form of bone foam, annular Smoking regime is corresponding with from center spray cooling water, bone mud to
External diffusion is just detached by annular bleed head 7, it is fine to detach effect；Suction channel 4 passes through the shell, corresponds on adjustment frame 4
Suction channel 4 is provided with slideway, and suction channel 4 is slidably installed in the slideway, so that it can be transported before and after 2 axis direction of drill bit
It is dynamic；Suction channel 9 is provided with outer limit plate 10 on the outside of corresponding 1 rear end of drillstock, and outer limit plate 10 and drillstock are arranged between 1 rear end
There is pressure spring 12, suction channel 9 is provided with interior limit plate 11, outer limit plate 10 and interior limit plate 11 on the inside of corresponding 1 rear end of drillstock
The amplitude that suction channel 9 moves forward and backward is limited jointly, pressure spring 12 is used to reset suction channel 9, avoid after detaching Wangue mud,
The sight of the blocking doctor of annular bleed head 7；The external negative pressure equipment in the rear end of suction channel 4, to generate negative pressure, the negative pressure is set
It is standby to can be aspiration pump, water pump etc..
When specifically used, first micro pump 5 is connect with cooling water source, the rear end of suction channel 4 and negative pressure equipment are connected
It connects；Then start micro pump 5 and negative pressure equipment, start to drill, while drilling, constantly infuse cooling water, realize real
Shi Jiangwen；When needing to aspirate bone mud, compressing suction channel 9 travels forward, and makes annular bleed head 7 close to working face, works as suction
After complete, release suction pipeline 9, under the action of pressure spring 12, annular bleed head 7 returns to original position, does not influence doctor's sight, is drilling
In the process, need continually to aspirate bone mud, the mode of operation of this elasticity simplifies the operation of doctor, very useful.
In order to guarantee that cooling water energy is synchronous with drilling, cooling-water duct 3 includes column-like paths 31 and is arranged in column-like paths
The tapered channels 32 of 31 front ends are provided with spring base 33 in column-like paths 31, plug 34, plug 34 are placed in tapered channels 32
It is provided between rear end and spring base 33 and holds out against spring 35, the outlet setting of tapered channels 32 is stretched out in the front end of plug 34.It uses
When, when drill bit 2 is connected on skull, plug 34 bounces back under the reaction of skull, and compression holds out against spring 35, to open gradually
The simultaneous implantation of cooling water is realized in contracting channel 32, when drill bit 2 is separated with skull, is held out against spring 35 and is held out against plug 34, will gradually
Contracting channel 32 is closed.When drill bit 2 drills skull, plug 34 can also close tapered channels 32 in time, and cooling water is avoided to inject cranium
It is intracavitary, improve safety.
In order to improve the reliability of plug 34, plug 34 includes ball and the protrusion that ball front end is arranged in, the ball
Rear end connect with spring 35 is held out against, the protrusion front end is in smooth arc-shaped and stretches out the outlets of the tapered channels 32；Make
Used time, the ball surface are contacted with the contact of tapered channels 32 for line, it is easy to are opened, in Recovery Process, by institute
State the guiding role of ball surface, plug 34 can smooth return, improve the smoothness of the movement of plug 34, avoid the occurrence of card
?.
Finally it should be noted that: above embodiments are only to illustrate the technical solution of the utility model rather than limit it
System；Although the utility model has been described in detail with reference to the preferred embodiment, those of ordinary skill in the art should
Understand: specific implementation of the utility model can still be modified or is equally replaced to some technical characteristics
It changes；Without departing from the spirit of technical solutions of the utility model, should all cover in the claimed technical solution of the utility model
In range.
