Abstract
The utility model discloses a reciprocating type bone saw which comprises: a drive rotational axis fixed to an inner cavity of a back seat; a transmission device, wherein, one end connects with a drive axis through a clasp mounted on the drive axis; a driven axis connected with the other end of the transmission device; a knife handle locked with the other end of the driven axis through a locking piece and mounted on a limit cavity of a front seat, a knife tool connected with the other end of the knife handle and mounted on a safe nozzle, the safe nozzle is arranged on a front seat through a limit nozzle. The transmission device comprises: a transmission block, a connecting rod connected with the transmission block through a bearing. The reciprocating type bone saw has advantages of convenient operation, high work efficiency and long service life.
Description
Technical field
This utility model relates to a kind of medical surgical operating theater instruments, more particularly, relates to a kind of reciprocating bone saw that is used for bone surgery.
Background technology
Known in the surgery field of surgical, employed bone saw is generally reciprocating bone saw in the bone surgery.At present, in the world in the Chang Yong reciprocating bone saw, the transmission of power generally by gear drive, take turns structures such as transmission or cam drive partially and realize.But above-mentioned drive mechanism is complex structure not only, and the operator need apply bigger power ability complete operation when using such bone saw.In addition, because the power main part of such bone saw load is bigger, is easy to damage, thereby causes the service life of such bone saw shorter.
The utility model content
At the deficiencies in the prior art, it is a kind of simple in structure, easy to operate and be difficult for impaired reciprocating bone saw that the purpose of this utility model is to provide.
For achieving the above object, this utility model provides a kind of reciprocating bone saw, the power rotating shaft that comprises the interior intracavity that is fixed in back seat, the actuating device that one end links to each other with line shaft by being installed in the snap ring on the line shaft, be connected the driven shaft of the other end of actuating device, be locked in the other end of driven shaft and be installed on handle of a knife in the limit chamber of front stall by locking part, and link to each other with the other end of handle of a knife and be installed on and be locked in cutter in the safe muzzle on the front stall by spacing mouth, wherein, actuating device comprises drive block and is connected connecting rod on the drive block by bearing.
More preferably, the line shaft of this reciprocating bone saw passes through bearing, liner and bearing fixing in the interior intracavity of back seat.
More preferably, this reciprocating bone saw also comprises the antifriction bearing that is connected between driven shaft and the handle of a knife.
More preferably, the cutter of this reciprocating bone saw comprises one chip duplicate rows rack saw, quantitatively the pointed tooth of molding double-disk duplicate rows rack saw or the marshallings that staggered mutually by two row constitutes.
Compared with prior art, the utlity model has following advantage:
1, because this reciprocating bone saw has utilized lever principle on power transmission, therefore only need apply less power gets final product complete operation, makes that operation is more convenient;
2, because this reciprocating bone saw has adopted bearing arrangement in actuating device, wearing and tearing and load that driven shaft is subjected to can be reduced in the reciprocating motion process, thereby effect, minimizing load can be improved.
Description of drawings
Fig. 1 is the cross-sectional view according to the reciprocating bone saw of this utility model preferred embodiment.
The specific embodiment
For describing technology contents of the present utility model and structural feature in detail, be explained in further detail below in conjunction with embodiment and accompanying drawing.
Fig. 1 shows the cross-sectional view according to the reciprocating bone saw of this utility model preferred embodiment.This reciprocating bone saw comprises: be fixed in the line shaft 21 in the inner chamber 111 of back seat 11 by bearing 3, liner 4 and bearing 5; The actuating device 22 that one end links to each other with line shaft 21 by being installed in the snap ring 211 on the line shaft 21; Be connected the driven shaft 23 of the other end of actuating device 22, the other end of this driven shaft 23 is provided with antifriction bearing 231; Be locked in antifriction bearing 231 and be installed on handle of a knife 24 in the limit chamber 121 of front stall 12 by locking part 6; And the cutter 25 that links to each other with the other end of handle of a knife 24, this cutter is installed on by spacing mouth 122 and is locked in the safe muzzle 13 on the front stall 12.
In addition, actuating device 22 comprises: drive block 221 and be connected connecting rod 222 on the drive block 221 by bearing 223.In addition, cutter 25 includes but not limited to one chip duplicate rows rack saw, quantitatively the pointed tooth of molding double-disk duplicate rows rack saw or the marshallings that staggered mutually by two row constitutes.
According to the operation principle of reciprocating bone saw of the present utility model be rotary power is imported line shaft 21 after, directly force in drive block 221 by snap ring 211, thereby reciprocating by the direction drivening rod 222 and the driven shaft 23 of drive block 221 change power again, finish work such as cut-out, grinding at last by cutter 25.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Every equivalence of doing according to this utility model changes and revises, and is all covered by claim of the present utility model.
