Abstract
The invention discloses an ultrasonic bone knife head. The ultrasonic bone knife head comprises a blade and a knife tip, wherein the knife tip is positioned at the front end of the blade and is used for converging all the energy of an ultrasonic bone knife to the knife tip part. Due to the adoption of the technical scheme provided by the invention, the cutting speed can be increased, the operation time is reduced, and the cutting degree and the cutting shape of a bone can be precisely controlled.
Description
Technical field
The present invention relates to technical field of medical instruments, relate in particular to a kind of piezosurgery osteotomy cutter head.
Background technology
In bone surgery, often use piezosurgery osteotomy to bone cut, grinding, planing, scraping or any reshaping.As shown in Figure 1, present piezosurgery osteotomy cutter head is multiple tooth, and the point of a knife part of broad is arranged, and how the point of a knife part is not effectively main cutting part.
There is following problem in this piezosurgery osteotomy cutter head: cutting speed is slow, and efficient is low, and carrying load ability is poor, wastes energy; Fracture easily, service life is low; Complex-shaped, difficulty of processing is high, and production cost is high.
Summary of the invention
The objective of the invention is to propose a kind of piezosurgery osteotomy cutter head, can improve cutting speed, reduce operating time, and can accurately control cutting output and shape bone.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of piezosurgery osteotomy cutter head comprises blade and point of a knife, and said point of a knife is positioned at the positive front end of blade, is used for whole energy centralizations with piezosurgery osteotomy to the point of a knife part.
The thickness of said point of a knife is greater than the thickness of said blade.
Said point of a knife is provided with circular groove.
Said point of a knife is provided with gable.
Also comprise blade and connecting thread, blade one end connects blade, and an end is connected with connecting thread, and blade one end is thick cylinder, and an end is thin cylinder, and is middle through arc transition, and positive die nut position is set, and connecting thread is used for being connected with ultrasonic transducer.
On the longitudinal central axis line that is centered close to cutter head of point of a knife, Yi Bian be triangle between two edges of nose center and blade, another side is a circular groove.
On the longitudinal central axis line that is centered close to cutter head of point of a knife, all be triangle between two edges of nose center and blade, and circular groove be set at leg-of-mutton mid portion.
On the longitudinal central axis line that is centered close to cutter head of point of a knife, partly being triangle near nose center between two edges of nose center and blade, partly is circular groove near blade edge.
On the longitudinal central axis line that is centered close to cutter head of point of a knife, all be triangle between two edges of nose center and blade, and two circular grooves be set at leg-of-mutton mid portion.
On the longitudinal central axis line that is centered close to cutter head of point of a knife, all be circular groove between two edges of nose center and blade.
Adopted technical scheme of the present invention, deep efficient is high, speed is fast, has reduced operating time, reduces less patient suffering, reduces doctor's labor intensity; The cutter head exquisiteness is small and exquisite, can accurately control cutting output and shape to bone, reduces the deep loss amount in the art, accelerates patient's recovery time; Hemostasis blood coagulation effect is arranged in deep process, reduce intraoperative blood loss; Reduce difficulty of processing, reduced production cost.

The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through the specific embodiment.
The main thought of technical scheme of the present invention is on the planform of piezosurgery osteotomy cutter head; Point of a knife is positioned on the central axis of whole cutter head; Thereby the energy that ultrasonic transducer produced is all converged at the point of a knife part (the most effectively working portion) of piezosurgery osteotomy cutter head; Converge and be a bit, make the point of a knife of cutter head partly have the strongest energy output, reach the strongest work.
Fig. 2 is the structural representation of piezosurgery osteotomy cutter head in the specific embodiment of the invention one.Fig. 3 is the side schematic view of piezosurgery osteotomy cutter head in the specific embodiment of the invention one.As shown in Figures 2 and 3, what this piezosurgery osteotomy cutter head adopted is single main serrated knife point dissymmetrical structure, comprises blade 1, point of a knife 2, connecting thread 3 and blade 4.
Point of a knife is positioned at the positive front end of blade, is used for whole energy centralizations with piezosurgery osteotomy to the point of a knife part.On the longitudinal central axis line that is centered close to cutter head of point of a knife, Yi Bian be triangle between two edges of nose center and blade, another side is a circular groove.
Blade one end connects blade, and an end is connected with connecting thread, and blade one end is thick cylinder, and an end is thin cylinder, and is middle through arc transition, and positive die nut position is set, and connecting thread is used for being connected with ultrasonic transducer.The connecting thread of cutter head afterbody is connected with specific ultrasonic transducer, and tightens, again ultrasonic transducer is connected in specific ultrasonic main frame, can carry out work with corresponding spanner.
Fig. 4 is the structural representation of piezosurgery osteotomy cutter head in the specific embodiment of the invention two.As shown in Figure 4, the structure basically identical of the piezosurgery osteotomy cutter head in the structure of this piezosurgery osteotomy cutter head and the specific embodiment one, just the thickness of point of a knife passes through arc transition greater than the thickness of blade between point of a knife and the blade.
The width that cuts out of point of a knife just greater than the thickness of blade, in operation process, the cutter stuck phenomenon just can not occur pressing from both sides when cutting the darker groove of thicker bone or cutting, window type otch so in use.In addition, point of a knife thickness has greatly also increased point of a knife intensity, has improved the service life of cutter head relatively.
Above-mentioned a kind of example that is shaped as of only enumerating point of a knife in the actual operation process, can adopt difform point of a knife according to different needs.
The point of a knife part can all be a circular groove, and the groove two ends are positioned at the blade edge both sides.
The point of a knife part can all be a gable also.
The point of a knife part can also be taked following shape:
On the longitudinal central axis line that is centered close to cutter head of point of a knife, all be triangle between two edges of nose center and blade, and circular groove be set at leg-of-mutton mid portion.
On the longitudinal central axis line that is centered close to cutter head of point of a knife, partly being triangle near nose center between two edges of nose center and blade, partly is circular groove near blade edge.
On the longitudinal central axis line that is centered close to cutter head of point of a knife, all be triangle between two edges of nose center and blade, and two circular grooves be set at leg-of-mutton mid portion.
On the longitudinal central axis line that is centered close to cutter head of point of a knife, all be circular groove between two edges of nose center and blade.
The above; Be merely the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, anyly is familiar with this technological people in the technical scope that the present invention disclosed; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
