Abstract
A kind of drill for craniotomy of forming by wind and drill bit etc. that is used for the neurosurgery clinical operation, its principal character is that a secondary epicyclic train gear is housed between wind and drill bit, the rotating ratio that cranium after the improvement bores between its wind and drill bit can reach 1: 4, helps to improve the effect of neurosurgery.
Description
The invention belongs to technical field of medical instruments, particularly a kind of hand-rail type drill for craniotomy that is used for the neurosurgery clinical operation.
Drill for craniotomy is the clinical indispensable apparatus of neurosurgery.At present general drill for craniotomy is divided with power mode and can be divided into three kinds in this area, and promptly bitbrace, pneumatic drill and electric drill wherein bore the most commonly used with the hand-rail type cranium again.The ratio that traditional hand-rail type cranium bores its drill bit and the rotating speed of wind is 1: 1, 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, but complex structure, involve great expense, need alternating current power supply or high pressure nitrogen, both use also safety inadequately of inconvenience as power source, adopt the preceding complexity of link of preparing of art of electric drill or pneumatic drill in addition, also pollute easily.
The objective of the invention is at the existing drill for craniotomy weak point of hand-rail type drill for craniotomy particularly, a kind of simple in structure, dependable performance is provided, is suitable for neurosurgery and opens the efficient quick hand drill for craniotomy that cranium uses.
For achieving the above object, technical solution of the present invention is to set up the epicyclic train gear that a pair is made up of ring gear, planetary gear and central gear between the wind of traditional hand-rail type drill for craniotomy and drill bit.After this improves, when the wind of drill for craniotomy rotates a week, drill bit can be corresponding rotations several weeks, thereby the speed of having accelerated to bore cranium has improved the effect of performing the operation.
Below with reference to accompanying drawing the present invention is further described.
Fig. 1 is a theory structure sketch map of the present invention.
Fig. 2 is the structural representation of an embodiment of the present invention.
Fig. 3 is the fundamental diagram of epicyclic train gear.
With reference to accompanying drawing, quick hand drill for craniotomy of the present invention is made up of wind 1 and drill bit 2 etc., the epicyclic train gear is installed between wind 1 and the drill bit, ring gear 3 and drill for craniotomy handgrip locking bar 7 Joints in the gear, central gear 5 connects with drill bit axostylus axostyle 1, planetary ring gear 3 and central gear 5 engagements, its wheel bearing connects with wind rotating shaft bar 6 simultaneously.During work, the operator passes through rotary handle crank 1 drive planetary gear 4 along ring gear 3 rotations, and then drives central gear and reach drill bit 2 acceleration rotations.For the structural stability of strengthening epicyclic train and improve the cranium driller and make effect, can in gear, be symmetrical arranged three planetary gears 4, simultaneously with ring gear 3, the gear ratio of planetary gear 4 and central gear 5 is defined as 3: 1: 1.Like this, when wind 1 rotated a week, according to the gear ratio formula of planet circular system, all numbers of the rotation of central gear 4 and drill bit 2 were 4.Number in the figure 7 is a handgrip.
Compared with prior art, cranium drilling tool of the present invention has the characteristics such as rotating speed is fast, good hand touch, dependable performance, can be widely used in the medical departments such as town and country, army, factories and miness, and help to improve the effect of neurosurgery.
Claims (3)
1, a kind of drill for craniotomy with wind 1 and drill bit 2, it is characterized in that between wind 1 and drill bit 2, being equipped with the epicyclic transmission that a pair is made up of ring gear 3, planetary gear 4 and central gear 5, wherein planetary gear 4 wheel bearings connect with wind rotating shaft bar 6, and central gear 5 connects with the drill bit axostylus axostyle.
2, drill for craniotomy as claimed in claim 1 is characterized in that having in the gear three symmetrically arranged planetary gears 4.
