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

A kind of ultrasonic osteotome bit

Technical field

The present invention relates to technical field of medical instruments, relate in particular to a kind of ultrasonic osteotome bit.

Background technology

In bone surgery, often use piezosurgery osteotomy to bone cut, grinding, planing, scraping or any reshaping.As shown in Figure 1, current ultrasonic osteotome bit is multiple tooth, has wider point of a knife part, and how point of a knife part is not effectively main cutting part.

There are the following problems for this ultrasonic osteotome bit: cutting speed is slow, and efficiency is low, and carrying load ability is poor, wastes energy; Easily fracture, service life is low; Complex-shaped, difficulty of processing is high, and production cost is high.

Summary of the invention

The object of the invention is to propose a kind of ultrasonic osteotome bit, can improve cutting speed, reduce operating time, and can accurately control cutting output and the shape to bone.

For reaching this object, the present invention by the following technical solutions:

A kind of ultrasonic osteotome bit, comprises blade and point of a knife, and described point of a knife is positioned at the positive front end of blade, for by whole energy centralizations of piezosurgery osteotomy to point of a knife part.

The thickness of described point of a knife is greater than the thickness of described blade.

Described point of a knife is provided with circular groove.

Described point of a knife is provided with gable.

Also comprise blade and connecting thread, blade one end connects blade, and one end is connected with connecting thread, and blade one end is thick cylinder, and one end is thin cylinder, middle by arc transition, and positive die nut position is set, and connecting thread is for being connected with ultrasonic transducer.

On the longitudinal central axis line that is centered close to cutter head of point of a knife, between two edges of nose center and blade, be triangle on one side, another side is circular groove.

On the longitudinal central axis line that is centered close to cutter head of point of a knife, between two edges of nose center and blade, be all triangle, and at leg-of-mutton mid portion, circular groove be set.

On the longitudinal central axis line that is centered close to cutter head of point of a knife, between two edges of nose center and blade, being triangle near nose center part, is circular groove near blade edge part.

On the longitudinal central axis line that is centered close to cutter head of point of a knife, between two edges of nose center and blade, be all triangle, and at leg-of-mutton mid portion, two circular grooves be set.

On the longitudinal central axis line that is centered close to cutter head of point of a knife, between two edges of nose center and blade, be all circular groove.

Adopted technical scheme of the present invention, deep efficiency is high, speed is fast, has reduced operating time, reduces patient's misery, reduces doctor's labor intensity; Cutter head exquisiteness is small and exquisite, can accurately control cutting output and shape to bone, reduces the deep loss amount in art, accelerates patient's recovery time; In deep process, there is hemostasis blood coagulation effect, reduce intraoperative blood loss; Reduce difficulty of processing, reduced production cost.

Fig. 1 is the structural representation of ultrasonic osteotome bit in prior art scheme.

Fig. 2 is the structural representation of ultrasonic osteotome bit in the specific embodiment of the invention one.

Fig. 3 is the side schematic view of ultrasonic osteotome bit in the specific embodiment of the invention one.

Fig. 4 is the structural representation of ultrasonic osteotome bit in the specific embodiment of the invention two.

The specific embodiment

Further illustrate technical scheme of the present invention below in conjunction with accompanying drawing and by the specific embodiment.

The main thought of technical solution of the present invention is in the planform of ultrasonic osteotome bit, point of a knife is positioned on the central axis of whole cutter head, thereby the energy that ultrasonic transducer is produced all converges at the point of a knife part (the most effective working portion) of ultrasonic osteotome bit, converge as a bit, make the point of a knife part of cutter head there is the strongest energy output, reach the strongest working effect.

Fig. 2 is the structural representation of ultrasonic osteotome bit in the specific embodiment of the invention one.Fig. 3 is the side schematic view of ultrasonic osteotome bit in the specific embodiment of the invention one.As shown in Figures 2 and 3, what this ultrasonic osteotome bit 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, for by whole energy centralizations of piezosurgery osteotomy to point of a knife part.On the longitudinal central axis line that is centered close to cutter head of point of a knife, between two edges of nose center and blade, be triangle on one side, another side is circular groove.

Blade one end connects blade, and one end is connected with connecting thread, and blade one end is thick cylinder, and one end is thin cylinder, middle by arc transition, and positive die nut position is set, and connecting thread is for being connected with ultrasonic transducer.The connecting thread of cutter head afterbody is connected with specific ultrasonic transducer, and tightens with corresponding spanner, then ultrasonic transducer is connected in to specific ultrasonic main frame, can carry out work.

Fig. 4 is the structural representation of ultrasonic osteotome bit in the specific embodiment of the invention two.As shown in Figure 4, the structure of the ultrasonic osteotome bit in the structure of this ultrasonic osteotome bit and the specific embodiment one is basically identical, and just the thickness of point of a knife is greater than the thickness of blade, between point of a knife and blade, passes through arc transition.

The width that point of a knife cuts out so in use is just greater than the thickness of blade, in operation process, just there will not be folder cutter stuck phenomenon while cutting the darker groove of thicker bone or cutting, window type otch.In addition, point of a knife thickness has greatly also increased point of a knife intensity, has relatively improved the service life of cutter head.

The above-mentioned one of only enumerating point of a knife is shaped as example, in actual operation process, can, according to different needs, adopt difform point of a knife.

Point of a knife part can be all circular groove, and groove two ends are positioned at blade edge both sides.

Point of a knife part can be also all gable.

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, between two edges of nose center and blade, be all triangle, and at leg-of-mutton mid portion, circular groove be set.

On the longitudinal central axis line that is centered close to cutter head of point of a knife, between two edges of nose center and blade, being triangle near nose center part, is circular groove near blade edge part.

On the longitudinal central axis line that is centered close to cutter head of point of a knife, between two edges of nose center and blade, be all triangle, and at leg-of-mutton mid portion, two circular grooves be set.

On the longitudinal central axis line that is centered close to cutter head of point of a knife, between two edges of nose center and blade, be all circular groove.

The above; be only the preferably specific embodiment of the present invention, but protection scope of the present invention is not limited to this, any people who is familiar with this technology is in the disclosed technical scope of the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
