Abstract
The present invention relates to the osteotomy saw that a kind of bone surgery is used, particularly a kind of directly to incision art open country, through surface of bone, according to operation plan, saw blade carries out altofrequency and small angle oscillation, finishes osteotomy saw multiple function, various complexity, high-leveled and difficult operation.
This saw also can be used for beating groove, block in carpenter and other the nonmetal operations, section etc.
Description
(technical field: International Classification of Patents A61 B17/14)
The present invention relates to the osteotomy saw that a kind of bone surgery is used, particularly a kind of according to operation plan, saw blade carries out altofrequency and small angle oscillation directly to incision art open country, through surface of bone, finishes the osteotomy saw of multiple function.
Board-like osteotomy saw of the prior art, the bone that can only execute the limb dividing art is from disconnected, and it is not only stupid but also slow to perform the operation.As do other operation, because of the form relation can not enter the osteotomy position, purposes is single.
Line formula osteotomy saw of the prior art, this saw is formed by braided steel wire.Can block long bone with it, but sawed-off surface of bone is irregular, easily becomes the Dou section; And must carry out subperiosteally extensively peeling off to the side, just can send into line formula osteotomy saw.Big with this saw damage cartilaginous tissue, and necessary cross-section whole bone, can not keep lateral part cortical bone, it is unfavorable that the broken ends of fractured bone of wedgeshaped osteotomy is stablized.Can not repeat osteotomy well accurately, more can not utilize and beat the bone groove, get the bone piece, its purposes is limited to.
Osteotome of the prior art, though can be used to deep, beat the bone groove and get the bone piece, because of Dou face extruding is arranged itself, section is not neat.And since the fragility of bone, easily splitting.If sclerotin is very hard, repeat deep difficulty.Often, easily bone is smashed, caused operative failure because of malfunction.
Garden disc type osteotomy saw can be swung osteotomy though can rotate maybe in the prior art, and it does not enter the art open country because of the structural relation of body.In clinical, how to tear Gypsum Fibrosum open with it.
The objective of the invention is to provide a kind of multi-functional osteotomy saw, it not only can finish the function of several osteotomy saw of the prior art flexibly, quickly and accurately, also possesses highlightedly directly to incision art open country, altofrequency and small angle oscillation, can finish the osteotomy function of the high-leveled and difficult operation of various complexity.
Task of the present invention is achieved in that 1. saw blades is installed in blade clamp and 2. goes up.9. 5. cam be connected with motor shaft.5. blade clamp U-lag is 2. arranged the front at cam.Location fulcrum hole (11) is arranged on the blade clamp symmetrical center line 2..The location fulcrum shaft is arranged 3. on the saw body.3. 5. cam be eccentric with the location fulcrum shaft.The location fulcrum shaft is 3. on motor shaft centrage 9..When 4. 5. cam contacted with the upper end of blade clamp U-lag 2., 1. saw blade was then complying with the location fulcrum shaft 3. to lower swing.When 10. 5. cam contacted with the lower end of blade clamp U-lag 2., 1. saw blade was then complying with the 3. upwards swing of location fulcrum shaft.5. cam under 9. motor shaft drives, whenever rotates a circle, and 5. cam just drives anchor clamps that 1. saw blade link to each other and 2. complying with the location fulcrum shaft and 3. swing up and down once.The motor high speed rotating, then saw blade is 1. synchronous with it, altofrequency, the swing of low-angle ground.
1. saw blade adopts one chip metal saw blade.Its sawtooth is little arc, and sawtooth is along the left and right arrangement of tooth body centrage, and pitch is 1.6 millimeters.The saw blade shape differs, can be according to operation needs, arbitrarily transposing.
Power of the present invention can adopt inorganic variable-speed motor, and adjustable extent 4000 is changeed-15000 rev/mins, and 220 volts of alternating voltages become the dc source of 24-36 volt through rectifier transformer.Also can adopt blast, as power sources such as compressed air or nitrogen.
Of the present invention simple in structure, weight is light, and is safe and reliable, low cost of manufacture, be convenient to implement bone surgery osteotomy, slot, burrow, cut the bone piece of various forms, and very smooth from disconnected surface of bone.Especially the present invention can carry out the osteotomy of position, deep, the osteotomy of the osteotomy of the osteotomy of privileged sites, the osteotomy of high-leveled and difficult operation, orthomorphia and the prosthetic replacement of various limbs etc.So saw is multi-functional high-quality novel osteotomy saw.Can be widely used in the bone surgery of each large and medium-sized hospital.
The present invention is used for clinical example:
Acute tibia osteomyelitis, 3 years old infant.Execute focal cleaning, tibia fluting, irrigation and drainage art.In the art, with osteotomy saw of the present invention, very successfully with the whole fluting of tibia.If with osteotome operation, need beat groove, because of the infant bone is very thin, it is one slow to be bound to, and two easy folds in a garments split, three easily broken.
Forearm flexor group sponginess vascular tumor, musculus flexor contracture hands deformity.At tumor resection, after musculus flexor prolongs, still residual deformity.Make of osteotomy of the present invention saw and to scratch ulna cripetura osteotomy, respond well.If with osteotome or scroll saw osteotomy, to be cut into etc. greatly scratching ulna, it is smooth that the cross section is difficult for, and can influence surgical effect.
Femoral shortening in the paci's operation in the rotary osteotomy, with osteotomy saw of the present invention, cuts standard, and surface of bone is neat, and para-position is tight, helps healing.If use the prior art osteotomy, influence surgical effect equally.
In knee, wedge osteotomy on the condylus medialis femoris, the infantile diplegia sequela, the operation that difficulty such as talipes equinovalgus are high is all carried out disposable wedge osteotomy with osteotomy saw of the present invention, and involutory tight, it is good to reset.This be prior art can not finish.
This saw also can be used for beating groove, block in the nonmetallic materials operation such as carpenter, section etc.
Note in the accompanying drawing:
1. saw blade 2. blade clamp 3. locate 4. U-lag upper end of fulcrum shaft
5. 6. 7. 8. micro machine of attaching plug of electrodeless variable-speed switch of cam
9. motor shaft 10. U-lag lower end (11) location fulcrum hole
