Abstract
The utility model relates to an ultrasonic chisel for removing bone substance in operations, which belongs to the technical field of medical equipment used in cementum removal operations. The utility model is composed of an ultrasonic generator and a hand machine, wherein a machine head is arranged at the front end of the hand machine; after the improvement, the machine head is composed of a connecting body and a working end; saw teeth are arranged at a cutting edge part of the working end. An ultrasound chisel is formed by that a working head which is provided with the saw teeth and file patterns is matched with the ultrasonic generator and an energy converter of the existing ultrasonic dental unit. When used in bone substance removal operations, the utility model has the advantages of high bone removal efficiency, small vibration and little pain of patients. Because the working head does reciprocating motion, soft tissue injury caused by a worm wheel drill is effectively avoided. Clinical trials prove that the utility model has the characteristics of high patient tolerance degree, little intraoperative tissue damage, low postoperative infection probability, simple doctor operation, etc. The cost of the utility model is lower than that of foreign equipment. The utility model has wide application space.
Description
Technical field
This utility model relates to a kind of medical operation apparatus, and particularly the employed apparatus of boning in the Oral and Maxillofacial Surgery operation belongs to technical field of medical instruments.
Background technology
Usually need spend the bone object tool in the Oral and Maxillofacial Surgery extraction,, often need to remove the part alveolar bone and be beneficial to extracting of tooth as in pulling out the process of block teeth.The method that generally adopts is the chiso-mallet method at present, this method makes the patient feel terrified usually, and the vibrations of knocking the cutter handle with hammer make the patient be difficult to tolerance, and operation process is very long and painful, a lot of patients abandon treatment owing to fear operation process, thereby cause the state of an illness to increase the weight of and even worsen.Other has some odontologist then to adopt high speed worm gear dental drill to bone, this method can make the patient avoid the hardship of chiso-mallet, but reason owing to operating theater instruments self, cause easily in the art, post-operative complication, as causing the postoperative subcutaneous emphysema with the gases at high pressure spraying because of high speed worm gear dental drill, because of being involved in drill point, soft tissue forms damage, or the like.According to the related data introduction, abroad the someone uses a kind of miniature reflex saw or goose saw to bone, and therapeutic effect is better, but apparatus expensive, the treatment cost is very high, is difficult to promote the use of.
Summary of the invention
This utility model is used for solving the defective of above-mentioned prior art and provides a kind of corrective surgery misery, security performance height, cheap being used to of alleviating to perform the operation and remove the ultrasonic cutter of sclerotin.
The alleged problem of this utility model solves by the following technical programs:
A kind of be used for performing the operation remove the ultrasonic cutter of sclerotin, comprise supersonic generator and mobile phone in the formation, the mobile phone front end is provided with head, its special feature is: described head is made up of connector and working end, the blade in the working end is provided with sawtooth.
Above-mentioned be used for performing the operation remove the ultrasonic cutter of sclerotin, sword side plane position, described working end is provided with the cut of file, described connector tail end is provided with the atomized water spray orifice, the working end is led in the outlet of atomized water spray orifice.
Above-mentioned be used for performing the operation remove the ultrasonic cutter of sclerotin, described working end is dagger shape or tulwar shape, its overall size is: long 10~15 millimeters; Wide 2~4 millimeters; Thick 0.5~1.5 millimeter, the angle D of working end and connector is 0~90 degree.
Above-mentioned be used for performing the operation remove the ultrasonic cutter of sclerotin, the between cog spacing of described working end sawtooth is less than the shake working head of the cut of file of working end, promptly constitute a ultrasonic cutter, it is in the operation process of boning, the efficient of boning height, vibrations are little, the patient suffering is little, and, can effectively avoid the soft tissue injury of worm gear brill because of working head is reciprocating motion.Show that through clinical trial the utlity model has patient's tolerance degree height, tissue injury is few in the art, the postoperative infection probability is low, and the doctor operates characteristics such as relatively easy.Particularly it can make full use of the existing machine equipment that cleans one's teeth, a tractor serves several purposes, or as cleaning one's teeth the adnexa of machine, and its cost cost is far below overseas equipment, therefore has application space widely, good market prospect and social benefit.

The specific embodiment
Referring to Fig. 1, basic comprising of the present utility model comprises supersonic generator 1 and mobile phone 3, is provided with transducer in the mobile phone, and it is identical that described supersonic generator and mobile phone and the existing machine of cleaning one's teeth are provided with, and is provided with head 2 at the mobile phone front end.
Key improvements of the present utility model is at head, and referring to Fig. 2, Fig. 3, head 2 is made up of connector 2-1 and working end 2-2, and connector is provided with the connecting thread 2-3 of being convenient to change, and the blade in the working end is provided with sawtooth 2-6.Its operation principle is: ultrasound wave outputs to the working end by the vibration of transducer conversion, makes the working end produce high-frequency vibration, and the sawtooth position of working end then can be to dentale high speed sawing.Pressure and Oscillation Amplitude are all very little during work, and the patient feels that misery is very little, the tolerance degree height, but because frequency is very high, the bone efficient of dieing height.Fracture for avoiding osseous tissue that working end clamping tension is caused, be provided with cut of file 2-5 at sword side plane position, working end, the cut of file can also be increased work efficiency.Be provided with atomized water spray orifice 2-4 in the connector, the working end is led in the outlet of atomized water spray orifice, the atomized water spray orifice can be connected sterile distilled water from pressure vessel, spray the working end, under dither, form water smoke, has very high cooling effectiveness, postoperative subcutaneous emphysema and the infection that can also avoid high speed worm gear dental drill to cause simultaneously with the gases at high pressure spraying.Particularly the damage of worm gear dental drill to soft tissue avoided for moving back and forth in the working end.
Be to adapt to doctor's operation, the shape of working end can be other shape according to action need also as Fig. 2, dagger shape shown in Figure 3, as Fig. 4, tulwar shape shown in Figure 5, diamond shaped, semicircle shape as shown in Figure 7 as shown in Figure 6 certainly.The angle D of working end and connector is 0~90 degree, long 10~15 millimeters of working end size; Wide 2~4 millimeters; Thick 0.5~1.5 millimeter.Test shows that the between cog spacing of working end sawtooth is to be advisable less than an amplitude.
