Abstract
The utility model relates to a medical high pressure sterilizing electric saw, which is used for sawing bones in orthopaedic operations. The utility model converted the rotary movement of a motor into the reciprocating movement of a saw blade by a driving cam and a driven cam, a restoring spring, and other similar accessories. The utility model has the advantages of simplicity and practicality. The medical high pressure sterilizing electric saw can shorten the time of operations, so the labour intensity of doctors and the pain of patients can be relieved.
Description
This utility model belongs to medical apparatus and instruments.
In the present domestic bone surgery, hand saws is generally all used in the cut-out of skeleton, sawing speed is slow, prolongs operating time, and doctor's labor intensity is big.
The objective of the invention is to design a kind of simple and practical, medical electric saw that price is lower.
Technical solution of the present utility model is to drive power transmission shaft rotation with micro machine by drive mechanism, actuating cam and inverted cam are installed on the power transmission shaft successively, wherein actuating cam is fastening is installed on the power transmission shaft, inverted cam is linked on the power transmission shaft by sliding matching mode, actuating cam contacts with the cam face of inverted cam, the other end of inverted cam is equipped with saw blade folder and saw blade successively, and the outer wall of inverted cam is equipped with back-moving spring.When power transmission shaft rotated, actuating cam also rotated, and inverted cam reciprocatingly slides on power transmission shaft thereupon, thereby it is reciprocating to drive saw blade, realized the action of sawing skeleton.
This electric saw is simple in structure, thereby low price; Sawing speed is fast, can shorten operating time, thereby alleviates doctor's labor intensity and patient's misery.
Fig. 1 is a cutaway view of the present utility model, and as Figure of abstract.
Further specify below in conjunction with 1 pair of this utility model of accompanying drawing:
This utility model constitution state is as follows: the rotating shaft 25 of micro machine 24 tightens travelling gear 23 is installed, gear 23 meshes with three driving gears of driving tooth wheel set 22, the central shaft of these three driving gears is fastened on the drive 21, the central shaft of drive 21 is equipped with travelling gear 10, travelling gear 10 is meshed with three driven gears of driven tooth wheel set 20, the central shaft of these three driven gears is fixedly mounted on the drive 19, the axle center of drive 19 is connected with power transmission shaft 17, of the present utility model being characterised in that is equipped with actuating cam 9 that has oblique convex surface and the inverted cam 6 that has projection successively on the power transmission shaft 17, its cam 9 fastening being installed on the power transmission shaft 17, cam 6 is linked on the power transmission shaft 17 by sliding matching mode, cam 9 contacts with the convex end face of cam 6, the other end of cam 6 is equipped with saw blade folder 2 and saw blade 1 successively, it is that fixedly saw blade presss from both sides 2 nut that the outer wall of cam 6 is equipped with back-moving spring 26,3.
The periphery of cam 6 is equipped with metal ferrules 4 and sheath body 5 successively, back-moving spring is installed between the end and cam 6 outer wall lobe of sheath body 5, cam 6 outer walls have guide chute 27, the other end of sheath body 5 is equipped with guide finger 7, guide finger 7 is inserted in the guide chute 27, preventing that cam 6 from swinging when reciprocating vertically, thereby rock when preventing the saw blade sawing.
After motor 24 energisings, rotating shaft 25 drives travelling gear 23, driving tooth wheel set 22, drive 21, travelling gear 10, driven tooth wheel set 20, drive 19, power transmission shaft 17, actuating cam 9 rotations successively, because the effect of back-moving spring 26, gathering sill 27 and guide finger 7, inverted cam 6 is under the promotion of actuating cam 9, do straight reciprocating motion, the saw blade 1 in the saw blade folder 2 is realized the action of sawing skeleton.
8,11,12,14,15,16 are respectively in the middle part of this electric saw and the shell of afterbody among Fig. 1, and motor 24 is installed in the mesochite 12, and the afterbody of motor 24 has been equipped with the cushion block 13 of liner and sealing function.In the junction of fore shell 11 and mesochite 12, the junction of mesochite 12 and cushion block 13 and tail shell 14 has respectively and realizes the sealer 28 that is sealed and matched, thereby make this utility model can carry out the integral high pressure steam sterilization, prevent postoperative infection.Sealer 28 can be sealing ring or synthetic resin.
