Abstract
The utility model discloses a kind of special osteotome of foramen intervertebrale lens, including handle, blade, sleeve and cutter head, handle is hollow or solid cylinder, handle two ends are connected to blade and cutter head, and sleeve is wrapped in outside handle, and blade is cylinder tangent plane body, cylinder tangent plane body is the direction tangent plane along cylinder axis, cutter head is disk, and disk is provided with locator, and the lateral edges of one of edge of locator with blade axially are flushed.The utility model is provided with sleeve, it is to avoid infection, simultaneously because osteotome handle is corresponding with sleeve, therefore handle will not influence each other and change the position of osteotome with sleeve, can accurately learn the position of osteotome, prevent nerve to be damaged, improve security.
Description
Technical field
The utility model is related to medical equipment, and in particular to a kind of special osteotome of foramen intervertebrale lens.
Background technology
Foramen intervertebrale lens are similar with spinal endoscopes, are a pipes equipped with light, it from patient body side or
Side rear enters intervertebral foramen, implements to perform the operation in trouble free service trigonum, is that, effect minimum to patient trauma is best in similar operation
Disc herniation minimally-invasive treatment.Current foramen intervertebrale lens operation has two kinds during the taking-up bone of intervertebral shaping is carried out
Apparatus：Bone drill and trepan, both apparatuses are all circular, there is the risk of injured nerve.Because both apparatuses only have three points
One of left and right and bone-contact, neural damage occurred mainly in the space being not in contact with bone.Simultaneously at present osteotome by
In the limitation of its shape and length, it can not be applied in intervertebral hole forming.
Utility model content
It can be applied in foramen intervertebrale lens operation during intervertebral foramen formation the utility model proposes one kind, it is to avoid thorn
Swash nerve, the special osteotome of safe foramen intervertebrale lens.
To achieve these goals, the utility model is achieved through the following technical solutions：
A kind of special osteotome of foramen intervertebrale lens, including handle, blade, sleeve and cutter head, the handle are hollow or filled circles
Cylinder, the handle two ends are connected to blade and cutter head, and the sleeve is wrapped in outside handle, and the blade is cylinder tangent plane
Body, the cylinder tangent plane body is the direction tangent plane along cylinder axis, and the cutter head is disk, and the disk is provided with locator, institute
Lateral edges of the one of edge of locator with blade axially are stated to flush.
Further, the radian of the blade end is 120 ° -180 °.
Further, the length of the sleeve is not more than the length of handle.
Further, lateral edges of the left hand edge or right hand edge of the locator with blade axially are flushed.
Further, the diameter of the blade is more than the diameter of handle.
Further, it is excessive for circular arc between the blade and handle.
The special osteotome of the utility model foramen intervertebrale lens, its advantage is：
(1) osteotome blade is arc, and the circular arc degree that cross section is is 120 ° -180 °, can completely and bone-contact, it is to avoid
The possibility that the sharp part and nerve of bone drill and trepan are in contact, prevents nerve to be damaged, improves security.
(2) the utility model osteotome is provided with sleeve, it is to avoid infection, simultaneously because osteotome handle is corresponding with sleeve,
Therefore handle will not influence each other and change the position of osteotome with sleeve.
(3) locator is provided with osteotome cutter head, can accurately learns the position of osteotome.
(4) the utility model osteotome due to blade and handle on the same axis, therefore be vertical advance；And bone drill and ring
Saw and advance for manual rotation, exist after cutting bone and fall through suddenly and the danger of injured nerve；And the utility model osteotome is vertical
Into, it can avoid suddenly falling through and the generation of the situation of injured nerve, it is safe.
(5) intervertebral foramen bone and nerve in the middle of have ligamentum flavum interval, vertically into osteotome will not cut ligamentum flavum, improve
Security.
(6) osteotome does not enter canalis spinalis, is not take up intravertebral space, it is to avoid stimulate nerve.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, before creative labor is not paid
Put, other accompanying drawings can also be obtained according to these accompanying drawings.

Fig. 2 is the side schematic view of the special osteotome of the utility model foramen intervertebrale lens；
Fig. 3 is the schematic cross-section of blade.
1- handles, 2- blades, 3- sleeves, 4- cutter heads, 5- locators.
Embodiment
The utility model is further described with reference to specific embodiment and accompanying drawing.
A kind of special osteotome of foramen intervertebrale lens as Figure 1-3, including handle 1, blade 2, sleeve 3 and cutter head 4, handle 1 is
Hollow or solid cylinder, the two ends of handle 1 are connected to blade 2 and cutter head 4, between blade 2 and handle 1 for circular arc excessively,
Prevent tip or sharp edges from occurring then causing the stimulation to nerve.Sleeve 3 is wrapped in outside handle 1, and the length of sleeve 3 is little
In the length of handle 1, the design of sleeve 3 avoids infection, simultaneously because osteotome handle 1 is corresponding with sleeve 3, therefore handle
1 will not influence each other and change the position of osteotome with sleeve 3, and blade 2 is cylinder tangent plane body, and cylinder tangent plane body is along cylinder axis
Direction tangent plane, the radian of the end of blade 2 is 120 ° -180 °, and cutter head 4 is disk, and disk is provided with locator 5, a left side for locator 5
The lateral edges of the axle of edge or right hand edge with blade 2 along handle 1 are flushed, and can accurately learn the position of osteotome；Blade 2 it is straight
Footpath is more than the diameter of handle 1, and blade 2 can be made exposed, convenient operation.The utility model is provided with sleeve 3, it is to avoid infection, simultaneously
Because osteotome handle 1 is corresponding with sleeve 3, therefore handle 1 will not influence each other and change the position of osteotome, energy with sleeve 3
Enough positions for accurately learning osteotome, prevent nerve to be damaged, improve security.
The technical scheme that the utility model embodiment is provided is described in detail above, it is used herein specifically
Individual example is set forth to the principle and embodiment of the utility model embodiment, and the explanation of above example is only applicable to side
Assistant solves the principle of the utility model embodiment；Simultaneously for those of ordinary skill in the art, implement according to the utility model
Example, will change, in summary, this specification content should not be construed as in embodiment and application
To limitation of the present utility model.
