Description
Technical field
Medical field of the present invention, specifically a kind of medical bone drill.
Background technique
Bone drill is often used in medical, is frequently necessary to be used in neurosurgery, cardiothoracic surgery, orthopaedics, Department of B urn etc., existing
Some bone drills be usually it is electronic, pass through rotation aperture on corresponding bone of a motor control drill bit.It is existing
There is the following aspects in bone drill: first, existing drill bit majority cannot be replaced, minority being capable of better bone
In brill, in terms of replacement not；Second, when boring, dynamics is not easily controlled existing bone drill, firmly excessive sometimes, brill
It is too deep to influence operation.
Summary of the invention
The present invention is the problems in existing in order to solve, and provides a kind of medical bone drill, including hand handle, drill body and drill bit, hand
Being separately fixed on drill body with drill bit, drill bit is equipped with motor, and the drill bit is equipped with fixing seat and drill bit is dismountable
Connection, the fixing seat includes a recessed fixation seat shell, is equipped with rotating bar among fixed seat shell and connects with motor, turns
The end of lever is equipped with driving gear, driving gear and fixed gear teeth and fixed gear is three, is set on each fixed gear
There is the fixed link with fixed gear shaft to parallelly distribute on, fixed end is equipped with fixing head, rotates rotating bar by motor and drives
Driving gear, driving gear drive fixed gear, and fixed gear band turn lever rotation, fixed gear and driving gear are solid respectively
It is scheduled on pedestal；
In some embodiments, the opening for placing fixed gear is equipped in fixed seat shell, enable gear from
By rotating, not excessive gear can not need setting hatch frame when fixed seat shell transfer is dynamic, in the preferred case,
Three fixed gear set specifications are the same, and the radius of driving gear is less than fixed gear.
Hand handle, drill bit and motor use existing technology in the present invention, and drill bit of the invention can be various differences
Model the versatility of bone drill can be improved according to clinical more preferable different drill bit when in use.
The drill bit includes a screen post and drilling rod, and the screen post is stuck in fixed link.
Specific usage mode is as follows: when three fixed gears are in a direction, being usually fixed bar from master
Moving gear is farthest, and fixing head is distributed generally along the tangential direction of fixed gear, this when screen post can be stuck in rule
In fixed pole, with hand fine rotation fixed link, fixing head can block screen post, and three fixed links will tightly bite detent
Column, and then it is able to drive screen post rotation.The advantages of this mode, mainly there is three: first, it is easy for installation, screen post need to only be put
In the space surrounded into fixed link, fine rotation fixed link；Second, fixed force is strong, fixed link and detent can tightly be stung
Firmly, due to the rotation of fixed gear, fixed link around fixed gear central axis direction, with the rotation of fixed gear, three
Space between fixed link can be smaller and smaller, and then can get one's teeth into screen post；Third, unclamping aspect；Needing more preferable bore
When head, it is only necessary to gently by fixed column backwards rotation.
As an improvement, the drill bit further includes having the first rotation seat connected with drilling rod, rotation seat is equipped with motion bar,
The end of motion bar is fixed with movable block；Screen post is fixedly connected with connecting rod, and connecting rod end integrated molding has connection sheet, connection
Piece is fixedly connected with the second swivel base, and the second swivel base is equipped with loose slot, and movable block is located in loose slot, and only can be along moving down on loose slot
Dynamic, the bottom of loose slot is equipped with one for the channel that portable pillar passes through, by elasticity between the first rotation seat and the second rotation seat
Part connection, and elastic component is in compressive state.
The compressive preload power of elastic component of the invention can need to be configured, the suitable threshold value of this preload force, control
Transformation critical point between rigidity and elasticity processed, the size of preload force need to control movable block according to critical point and are controlled.
As an improvement, the elastic component is spring or the standby elastic piece of rubber system, rubber in the preferred case, is used
Fluorine silica gel, the fluorine silica gel include 100 parts of fluorine silicon raw rubber, 1 part of silane coupling agent, 5 parts of silicon carbide, 0.5 part of cobalt and 10
The fluorosilicon oil of part carries out surface using traditional handicraft and is modified, is kneaded and prepares elastic slice.Elasticity prepared by the present invention has longer
When the service life (present invention be hit by a bullet piece be in compressive state for a long time).
As an improvement, first rotation seat is equipped with the protective shell that can wrap up spring, the protective shell can
To wrap up the second rotation seat in whole or in part.
As an improvement, the connection sheet and the second rotation seat is connected by screw to.
As an improvement, the section of the movable block and loose slot is regular hexagon, movable block covers in screen post, and
And it is equipped with a nut in screen post and fixes and limit movable block far from the movement of the first rotation seat direction.
The preferred drill bit can have both rigidity and elasticity, when the axial compressive force that drill bit is subject to is little, activity
Block is located at the bottom of loose slot, will not rotate along the direction of loose slot, axis will not occur for the first rotation seat and the second rotation seat
To movement, when axial pressure is greater than certain force (extruding force of movable block and loose slot), this when, movable block was along work
Dynamic slot is mobile and then the first rotation seat is moved axially along the second rotation seat, and drill bit is in an elastic state, this elasticity
Bone can be effectively protected to avoid drill bit to the overexercise of bone in state.
