Abstract
Provided is a medical reciprocating saw handset which comprises a driving mechanism disposed in a case body and a reciprocating saw main body engaged and connected with the front end of the case body. The utility model is characterized in that a straight bearing is arranged on the reciprocating saw main body, a reciprocating shaft is engaged with the straight bearing, the rear end of the reciprocating shaft is connected with the output end of the driving device disposed in the case body, the front end of the reciprocating shaft is connected with a saw blade, and a screw is locked to achieve fixing. The utility model has the advantages that a stainless steel straight bearing is employed as a support of the saw handset, the sliding friction of the original sliding bearing is replaced by the sliding friction of the straight bearing, which is characterized by high kinematics accuracy, low vibration and small heat, thereby effectively resolving the weaknesses of the existing saw handset and preferably satisfying the clinical demands.
Description
Technical field
This utility model relates to a kind of medical reciprocating saw mobile phone, is used for the reciprocating sow mobile phone of osseous tissue cutting in the power set of especially performing the operation.
Background technology
The reciprocating sow mobile phone is a kind of instrument that carries out osseous tissue cutting in the surgical operation, loads onto behind the saw blade under power drive high speed by saw blade and moves back and forth and can carry out the cutting of osseous tissue quickly and accurately.Existing saw mobile phone exists that sliding bearing is easy to wear, the saw blade kinematic accuracy is not high, noise is big, the heating important disadvantages, and the doctor uses inconvenience, safety relatively poor in operation process.
Summary of the invention
For solving the above-mentioned shortcoming that the saw mobile phone exists, this utility model provides a kind of medical reciprocating saw mobile phone, and its reciprocating precision height, heating are slightly, vibration is little, noise is low, can satisfy the requirement of clinical operation better.
A kind of medical reciprocating saw mobile phone described in the utility model comprises the reciprocating sow main body that is located at the intravital drive mechanism of shell, is connected with the housing front end, it is characterized in that, is provided with linear bearing on the reciprocating sow main body; Reciprocating shaft cooperates with linear bearing, and the drive mechanism outfan in the rear end of reciprocating shaft and the shell is hinged, and the front end of reciprocating shaft is connected with saw blade, and lock-screw is fixed.Adopt interference fit between linear bearing and reciprocating sow main body, guarantee the suitable magnitude of interference, the high speed by reciprocating shaft moves back and forth and drives saw blade and carry out back and forth cutting of high speed, and realization is to the cutting of osseous tissue.Reciprocating shaft sliding position surface adopts the above high rigidity of HRC60 to improve its wearability, utilizes the high accuracy of linear bearing to guarantee the stationarity of linear reciprocating motion, reduces vibration and noise, utilizes the rolling friction of linear bearing to reduce the heating of high-speed motion.
Described a kind of medical reciprocating saw mobile phone, its drive mechanism by the drive bevel gear of final drive shaft and front end, with the driven wheel of differential of drive bevel gear engagement, cooperate with driven wheel of differential from power transmission shaft, and the connecting rod that is connected of the eccentric shaft that is connected from the outfan of power transmission shaft and an end and eccentric shaft form; Final drive shaft is engaged on the body of drive mechanism by first group of bearing, is engaged on the body of drive mechanism by second group of bearing from power transmission shaft, and the body of drive mechanism is connected and fixed by screw and housing.Power is by final drive shaft → drive bevel gear → driven wheel of differential → from power transmission shaft → eccentric shaft → connecting rod → reciprocating shaft, the high-speed straight-line of realization saw blade moves back and forth.
Described a kind of medical reciprocating saw mobile phone, its drive bevel gear and driven wheel of differential are the circle-arc tooth bevel gear.The requirement of high speed transmission speed had both been satisfied in the employing of circle-arc tooth bevel gear, had reduced reciprocating noise again effectively.
Described a kind of medical reciprocating saw mobile phone, the rear end of its reciprocating shaft is by the rod hinge connection of the drive mechanism outfan in hinge and the shell.
This utility model prior art is compared and had the following advantages: this saw mobile phone uses the rustless steel linear bearing as supporting, replace the sliding friction of former sliding bearing with the rolling friction of linear bearing, have kinematic accuracy height, little, the little characteristics of generating heat of vibration, solve the shortcoming of existing saw mobile phone effectively, satisfied clinical demand better.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, the drive bevel gear 2-1 of final drive shaft 2 and front end is engaged on the body 16 of drive mechanism by first group of bearing 3, be engaged on the body 16 of drive mechanism by second group of bearing 6 and 7 from power transmission shaft 4, driven wheel of differential 5 cooperate from power transmission shaft 4, and making drive bevel gear 2-1 and driven wheel of differential 5 engagements, described drive bevel gear and driven wheel of differential are the circle-arc tooth bevel gear; Eccentric shaft 15 is connected at the outfan from power transmission shaft, and an end and the eccentric shaft of connecting rod 8 are connected; Drive mechanism is packed in the housing, and its body 16 is connected and fixed by screw 17 and housing.
Reciprocating sow main body 9 and housing front end are connected, linear bearing 10 is installed on the reciprocating sow main body, reciprocating shaft 11 cooperates with linear bearing 10, drive mechanism outfan-connecting rod 8 in the rear end of reciprocating shaft and the housing 1 is hinged by hinge 14, the front end of reciprocating shaft is connected with saw blade 13, and lock-screw 12 is fixing.
Make the saw mobile phone of the thrust slide supporting of crank slide block mechanism with linear bearing, the motion of flexible axle transmission and power drive slider-crank mechanism by a pair of circle-arc tooth Bevel Gear Transmission and pass on the execution cutter.The reciprocating shaft of saw mobile phone is actual to be exactly slide block in the slider-crank mechanism, and the high-speed straight-line by reciprocating shaft moves back and forth, and drives the saw blade high-speed straight-line and moves back and forth, thereby realize in the operation sawing to osseous tissue.
