Abstract
This utility model provides a kind of anterior cervical vertebrae soleplate curet, comprises the spoon bar with curvature, and described spoon bar is provided with scale; The first end of described spoon bar is connected with handle, and described handle is provided with anti-skidding portion; The second end of described spoon bar is connected with key bit, and the structure of described key bit is triangle, and described key bit top is provided with level and smooth cutting edge.Leg-of-mutton key bit structure has increased curet structural strength, reduces soft tissue and strikes off difficulty; And thinner key bit reduces the requirement to intervertebral space width, with the spoon bar of curvature, for striking off process, provide the better visual field, the design of anti-skidding portion has increased processing safety.
Description
Technical field
This utility model relates to medical appliance field, is specifically related to a kind of anterior cervical vertebrae soleplate curet.
Background technology
For commonly encountered diseases and the frequently-occurring disease clinically such as cervical spondylosis, prolapse of lumbar intervertebral disc, stenosis, under the invalid prerequisite of expectant treatment, main by intervertebral disc and the bony spur of excision pathological changes clinically at present, adopt curet to remove terminal plate of vertebral body cartilage, prepare good intervertebral space implant bed it is carried out to fusion treatment.
The key bit of traditional Cervical endplate curet is rectangle or water-drop-shaped, and when striking off endplate cartilage, not only hold is little, and strikes off thorough not; The key bit of tradition curet is thicker, need to strut intervertebral space to hold curet during operation; And spoon bar mostly is straight-bar, blocks local field of view during operation, affects operation safety.
For the above-mentioned defect of prior art, this utility model is proposed.
Utility model content
In view of this, this utility model provides a kind of anterior cervical vertebrae soleplate curet, comprises the spoon bar with curvature, and described spoon bar is provided with scale; The first end of described spoon bar is connected with handle, and described handle is provided with anti-skidding portion; The second end of described spoon bar is connected with key bit, and described key bit top is provided with cutting edge; The width of the cutting edge end of described key bit is greater than the described key bit end that is connected with spoon bar.
Described key bit be shaped as trapezoidal or triangle.
Described trapezoidal waist limit replaces with camber line.
The limit of described triangle except cutting edge replaces with camber line.
Described anti-skidding portion is a kind of in anti-slip veins, skid resistant course or anti-skidding frosting.
Described scale is between the middle part and the second end of described spoon bar.
Described curvature is single radian or becomes radian.
The radius of curvature of described single radian is 30～50mm.
The thickness of described key bit is 2～4mm.
The beneficial effect that this utility model produces is:
The key bit structural edge cutting edge that head end is wide and the narrow class of bar connecting place is triangular shaped is wider, with soleplate contact area is larger and structure is firmer, has increased the structural stability of curet; The scope that intervertebral space decompression and soleplate are processed is beloid, so the design of triangle key bit more meets operation custom;
Because key bit stability increases, making it is not affecting under the prerequisite of stability, key bit thickness is done thinlyyer (to compare to traditional key bit (5mm), can accomplish thick 2～4mm), because of cervical operation patient, often intervertebral space is narrower, thinner novel key bit can reduce and in operation process, excessively struts decompression, thus neuroprotective;
For straight-bar, with the spoon bar of curvature, can better expose operation local field of view, increase processing safety; And spoon bar near-end is with scale: can observe at any time the scale mark on spoon bar in operating process, grasp the degree of depth that spoon bar enters, prevent from that key bit from entering to take an advanced study into spinal cord injury.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, can more completely understand better this utility model.Accompanying drawing described herein is used to provide further understanding of the present utility model, and embodiment and explanation thereof are used for explaining this utility model, does not form to improper restriction of the present utility model, wherein:
Fig. 1 is the structural representation of a kind of anterior cervical vertebrae soleplate of this utility model curet.
Fig. 2 is part (A) enlarged drawing of the key bit of a kind of anterior cervical vertebrae soleplate of this utility model curet.
In figure: 1, handle 2, spoon bar 3, key bit 4, scale 5, anti-slip veins.
The specific embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
A kind of anterior cervical vertebrae soleplate curet as shown in Figure 1, comprise handle 1, spoon bar 2 and key bit 3, the first end of spoon bar 2 is connected with handle 1, the second end and key bit 3, between the middle part of spoon bar 2 and the second end, be marked with scale 4, during use, can observe at any time by scale 4 scale mark 4 of spoon bar 2, grasp the degree of depth that key bit 2 enters, prevent that key bit 2 from entering dark Spinal Cord.Level and smooth cutting edge is arranged on the top of key bit 2.Key bit 2 is triangular structure, and thickness can be as thin as 2～4mm (as 3mm), and level and smooth cutting edge is arranged at the top of key bit 3.
Handle 1 is provided with anti-skidding portion, and anti-skidding portion can be the anti-slip veins stricture of vagina 5 in the present embodiment, can be also independent skid resistant course, can also be anti-skidding frosting processing on handle 1 etc.
Preferably spoon bar 2 is with curvature as a kind of, and can be single radian or become radian, single radian, radius of curvature 30-50mm, 30,35,40,45,50mm radius of curvature is preferably the value that every 5mm is gap.For straight-bar, with the spoon bar 2 of curvature, can increase operation local field of view, effectively improved the processing safety of operation.
As mentioned above; embodiment of the present utility model is explained; obviously, as long as do not depart from fact inventive point of the present utility model and effect, the distortion that will be readily apparent to persons skilled in the art, within being all included in protection domain of the present utility model yet.
