Abstract
The invention relates to an ultrasonic orthopedic surgery saw which comprises a motor swinging handle, an ultrasonic generator and a cooling saw blade system. The ultrasonic generator comprises a piezoelectric energy exchanger, a conical amplitude transformer, a mounting seat and a saw blade joint. Because a combined structure of a traditional mechanical pendulum saw and an ultrasonic saw is adopted, electric energy is converted into mechanical energy by the piezoelectric energy exchanger and the conical amplitude transformer in the ultrasonic generator and can gasify water and fracture protein hydrogen bonds in hard bone tissue contacting with cooling saw teeth in a bone surgery by high-frequency ultrasonic vibration so as to thoroughly damage and fully cut bone tissue to be cut. When the ultrasonic bone surgery saw is used for an operation, the ultrasonic bone surgery saw can cut all bones comprising loose bones, cartilages and hard bones without damaging blood vessels and nervous tissue, prevent bone cells from being burnt or burnt dead in the surgery process due to low cutting temperature, protect the biological performance of the bone cells, promote the recovery of a patient after the operation and scarcely have saw blade loss.
Description
Technical field

In the present embodiment, above-mentioned mount pad 23 is fixed on the shell 16 by second rolling bearing 14 on first rotating shaft 231 and the 3rd rolling bearing 15 on second rotating shaft 232.
Be respectively equipped with clutch shaft bearing seat 17 that cooperates with second rolling bearing 14 and second bearing block 18 that cooperates with the 3rd rolling bearing 15 on the above-mentioned shell 16.In the present embodiment, above-mentioned clutch shaft bearing seat 17 is round bearing block, and second bearing block 18 is the circular arc bearing block.
In the present embodiment, above-mentioned shell 16 is positioned at second bearing block, the 18 other cross baths 35 that are provided with.
The bearing position centrage 36 of above-mentioned eccentric shaft 12 departs from motor shaft centrage 37.
In the present embodiment, above-mentioned first connector 25 is a studs, and second connector 26 is a screw.
Be equiped with the gauge tap 19 that is connected with motor 11 on the above-mentioned motor swing handle 1 with decelerator.
In the present embodiment, above-mentioned gauge tap 19 is the multifunction switch that can realize that cooling saw blade system 3 single oscillations, single supersonic vibration, swing and the compound three kinds of functions of supersonic vibration are switched.
In the present embodiment, above-mentioned flange 27 is a circular flange; The mounting groove 28 that the bottom of mount pad 23 is provided with is rectangular slot.
Operation principle of the present invention is as follows: as shown in Figure 7, when selecting switch 19 to be single oscillation, motor 11 energisings of the band decelerator that ultrasonic orthopedic surgery saw of the present invention is related begin rotation, pass through key, eccentric shaft 12, rolling bearing 13 and rectangular slot 28, make ultrasonic generator 2 integral body swing around rotating shaft 231 axis, because ultrasonic generator 2 is connected to an integral body with cooling saw blade system 3 by screw, so the motion of the saw body 31 of cooling saw blade system 3 also is the oscillating motion around rotating shaft 231 axis, when sawtooth 33 touches spongy bone or soft tissue, promptly can realize the machine cuts of bone.Because motor 11 is by slowing down, thereby the frequency of vibration that produces can be not too high, thereby the osseous tissue of cut place and saw blade temperature can be not too high, but for the sake of security, can be alternative liquid coolant such as brine ice or disinfectant solution be transferred to sawtooth 33 by infusion tube 34 and liquid interface 32 and saw body 31, to reach the purpose that reduces otch and saw blade temperature by outside syringe pump.
When selecting switch 19 to be single supersonic vibration, the produce power conversion under the driving of power supply outside of the related piezoelectric transducer 21 of ultrasonic orthopedic surgery saw of the present invention, electric energy is converted into dither, by being connected with conical horn 22, make amplitude enlarge, feasible cooling saw blade system 3 body vibrations that are installed in conical horn 22, because conical horn 22 is to be installed on the mount pad 23 of band rotating shaft by a circular flange 27 that is positioned at zero shift node 29 places, thereby mount pad 23 can't produce vibration.When sawtooth 33 touched hard bone, the water in the os osseum histiocyte was vaporized rapidly under dither, the albumen hydrogen bond rupture, finished cutting thereby the realization osseous tissue thoroughly destroys.In the time of cutting; alternative liquid coolant such as brine ice or disinfectant solution are transferred to sawtooth 33 by infusion tube 34 and liquid interface 32 and saw body 31 by outside syringe pump; to reach the purpose that reduces otch and saw blade temperature; can avoid osteocyte in cutting process, to be burnt or burn to death, protect the biological property of osteocyte effectively.Simultaneously, simple supersonic vibration only has destruction to the osseous tissue of particular stiffness, can not be corrupted to blood vessel, nervous tissue and soft tissue.
When selecting switch 19 to be swing and supersonic vibration compound tense, the ultrasonic orthopedic surgery saw comprehensive above-mentioned single oscillation of energy of the present invention and single supersonic vibration function, the supersonic vibration cutting is worked when the higher os osseum of the hardness ratio that is cut bone, when the hardness ratio that is cut is low, mainly be that goose saw works, thereby can realize the cutting of os osseum, spongy bone and hyaloidin bone material.
Can select the compound three kinds of functions of single oscillation, single supersonic vibration, swing and supersonic vibration to carry out the osseous tissue cutting according to the actual requirements by ultrasonic orthopedic surgery saw of the present invention, all bone cuttings that comprise spongy bone, hyaloidin and os osseum matter can be optionally finished, blood vessel and nervous tissue can be do not destroyed.And cutting temperature is low, avoids osteocyte to be burnt in operation process or burn to death, and the biological property of protection osteocyte can promote the recovery behind the corrective surgery, does not have the saw blade loss substantially.Thereby the present invention is a ultrasonic orthopedic surgery saw a kind of reasonable in design, convenient and practical, powerful.
