Abstract
The present invention proposes osteotome under a kind of split type mirror, including handle, straight-bar and cutter head；Described handle is arranged at one end of straight-bar；Described cutter head uses demountable structure to be fixed on the other end of straight-bar.During use, after first straight-bar being placed in endoscope path way, the cutter head being suitable for is connected again in the straight-bar end passing endoscope end, after having connected, osteotome under split type mirror is positioned over lesion locations by working column together with endoscope, such that it is able to the operation that has of osteotome carried out under the conditions of the most lower, cutter head can be convenient for changing at any time when carrying out different operating, being not required to pull out straight-bar from endoscope path way, easy to use, safety is high；It is easier to have an effect when using after arranging handle, the operation of cutting in operation can be completed, reduce the use tapping operation, improve stability and the fineness of operation technique.
Description
Technical field
The present invention relates to technical field of medical instruments, be specifically related to osteotome under a kind of split type mirror.
Background technology
It is frequently necessary to use osteotome in bone surgery, the osteotome used the most clinically is integral type mostly
Osteotome, cutter head and knife bar are integrally machined and form.During Clinical practice, require cutter head according to the operation of difference operation
It is designed to different shapes, owing to the osteotome of integral type is only machined with a kind of cutter head, is therefore comparing again
Several osteotome can be used during miscellaneous operation, make troubles to operation preparation, and doctor frequently changes bone
Chisel can increase infection risk.
It addition, when orthopaedics Minimally Invasive Surgery, generally use endoscope to implement operation in human body.In view of to the greatest extent
Amount reduces patient's wound, and generally endoscope path way is thinner, more therefore has bigger or special-shaped
The integral type osteotome of cutter head cannot pass through endoscope path way.Existing integral type straight-bar osteotome is peeped within coordinating
When mirror uses, its working range is only limitted to the place that straight-bar can be stretched over, it is impossible to complete imaging processing nerve root
The hyperosteogeny of head end and the such work of calcification part.The existing osteotome inadequate science of head end shape, can not during use
Well have an effect, easily skid, and bone surgery it is frequently necessary to bigger strength and can be only achieved surgical effect.
Being limited to reasons in structure, the operation of existing osteotome can not carry out cutting operation energetically, and therefore operation is mainly to tap
It is main, have ignored and first cut the skill use prized afterwards, add operation risk.
Summary of the invention
The invention aims to overcome above-mentioned the deficiencies in the prior art, it is proposed that a kind of easy to use and energy
Install abnormity cutter head after with endoscope with the use of split type mirror under osteotome,.
For achieving the above object, the present invention uses following technical proposals: osteotome under a kind of split type mirror, including
Handle, straight-bar and cutter head；Described handle is arranged at one end of straight-bar；Described cutter head uses demountable structure solid
The other end due to straight-bar.After using the technical program, during use, after first straight-bar being placed in endoscope path way,
The cutter head being suitable for is connected, after having connected, by under split type mirror again in the straight-bar end passing endoscope end
Osteotome is positioned over lesion locations by working column together with endoscope, such that it is able to the operation that has of osteotome existed
Carry out under the conditions of under visual, cutter head can be convenient for changing when carrying out different operating at any time, be not required to directly
Bar pulls out from endoscope path way, easy to use, and safety is high；It is easier to have an effect when using after arranging handle,
The operation of cutting in operation can be completed, reduce the use tapping operation, improve the stability of operation technique
And fineness.
Preferably, threaded or draw-in groove is used to be connected between described cutter head and straight-bar.This programme simple in construction
Connect reliable, it is easier to realize.
Preferably, described handle is fixing with straight-bar end by the way of screw thread or welding is connected.
With improvement, one end that described straight-bar is connected with handle is "T"-shaped, and described "T"-shaped end is
One slide block；Described handle inner is provided with the chute being slidably matched with slide block along decreased food direction, and slide block holds
It is contained in chute.After using the technical program, slide block slides in chute thus changes on straight-bar and handle
Position relatively, when needing bigger turning moment, can slide into slide block one end of chute, thus increase
Add the moment of rotation, increase the strength prizing or cutting.
With improvement, described slide block is provided with Spring Card ball, with Spring Card ball sliding trace on described chute inwall
Corresponding position is provided with the detent that at least one is corresponding with Spring Card ball.Use Spring Card ball and detent
After coordinating location, when using handle to have an effect, the stability of handle is more preferable.
Preferably, described detent is three, and is separately positioned on two ends and the centre of chute inwall, bullet
Spring card ball makes straight-bar be positioned at two ends or the centre of handle respectively when snapping in corresponding detent.
Preferably, described handle is mutually perpendicular to straight-bar.Use this programme, can farthest increase use
Moment during power.
During use, after first straight-bar being placed in endoscope path way, then stretch out the end of endoscope path way even at straight-bar
Connect applicable osteotome cutter head, after having connected, osteotome under split type mirror is passed through working column together with endoscope
It is positioned over lesion locations, such that it is able to by all operations of osteotome in visual lower realization.
The invention has the beneficial effects as follows: cutter head and straight-bar use split-type structural, can first straight-bar be passed interior
Reconnect cutter head after sight glass passage, the cutter head of any abnormity therefore during operation, can be used, it is possible to achieve be visual
Under more fine safety operation, the process of the symptom such as narrow, ossified of such as nerve root rostral, expand
Visual safe operating range；It is provided with handle to make operator be easier to grasping to have an effect, such that it is able to
Carry out the operation of bone surgery cutting, reduce and tap operation, the most simple percussion operation is become percussion
With prize cut sled technology, add the stability of operation and the fineness of operation；Meanwhile, operation can be realized
Various osteotome cutter heads under middle mirror change installation at any time, very easy to use.
