Background technology
In orthopaedics therapy operation, generally be to do the resection operation of osseous tissue with the saw blade of high speed swinging by goose saw, medical apparatus is usually required safe, reliable, easy to operate.Medical swing saw of the prior art, some is the mode that adopts nut to compress for the installation of saw blade, installing or change saw blade in operation process needs to screw or unscrew nut with instruments such as wrench, inconvenient operation.In addition, because goose saw in use has certain vibration, this nut compresses the situation that nut loosening appears in mode easily, influences operation safety.Though the goose saw that has has adopted more convenient quick change saw-blade structure, the angle position of saw blade on goose saw all is fixed, needs sometimes in the operation can operate by the posture of adjusting assurance or health, influences the convenience of operation technique.
Summary of the invention
The purpose of this utility model provides a kind of saw blade quick change construction of medical swing saw, its reliable, variable-angle in saw blade location, and installation or replacing saw blade are convenient, fast, can better satisfy the requirement of clinical operation.
The saw blade quick change construction of medical swing saw described in the utility model, comprise swinging axle, the gland that cooperates with swinging axle and saw blade, it is characterized in that: the top of swinging axle is provided with draw-in groove, it on the draw-in groove disk, be provided with annular groove below the disk, center above the disk is provided with a blind hole, and the both sides of swinging axle are provided with and the vertical bar hole of blind hole; The both sides of gland are provided with through hole, and the annular groove below the uniform a plurality of equidistant cylinders on the anchor ring above it, the top disk of the upper end of a plurality of equidistant cylinders and swinging axle is corresponding; The shank of saw blade is provided with bayonet socket, is provided with a plurality of equidistant circular holes and semicircle orifice around the circular arc of bayonet socket; The draw-in groove corresponding matching on bayonet socket and swinging axle top; Circular hole around the circular arc of bayonet socket and semicircle orifice cooperate with cylinder above the gland; Button cooperates with blind hole above the disk of swinging axle top, and the bottom of button is provided with a radial direction through hole, is provided with the compression spring between the bottom of the lower end of button and blind hole; Drive link passes the through hole of gland both sides, the bar hole of swinging axle both sides, the radial direction through hole of button bottom; Swinging axle cooperates by bearing with the middle and lower part of cylindrical shell, and the periphery of gland and the top of cylindrical shell are slidingly matched; Fixedly connected with shift fork by alignment pin in the bottom of swinging axle.
This utility model compared with prior art has the following advantages: owing to adopt the button mode to install or change saw blade, so, convenient and swift; Because saw blade and gland adopt a plurality of cylinders to fix, so not only the saw blade location is reliable, and adjustable angle, has satisfied the requirement of clinical operation better; Both can be used for horizontal goose saw, can be used for vertical goose saw again.

The specific embodiment
Embodiment: this utility model is used for horizontal goose saw.
Referring to Fig. 1 to Fig. 7, the saw blade quick change construction of medical swing saw described in the utility model, the gland 2 and the saw blade 3 that comprise swinging axle 1, be slidingly matched with swinging axle; The top of swinging axle is provided with draw-in groove 1-1, is a disk 1-2 on the draw-in groove, is provided with annular groove 1-3 below the disk, and the center above the disk is provided with a blind hole 1-4, and the both sides of swinging axle are provided with and the vertical bar hole 1-5 of blind hole; The both sides of gland 2 are provided with through hole 2-1, and the circumference above it is provided with a plurality of equidistant cylinder 2-2, and the annular groove 1-3 below the top disk of a plurality of equidistant cylinders 1 upper end and swinging axle is corresponding; The shank of saw blade 3 is provided with bayonet socket 3-1, is provided with a plurality of equidistant circular hole 3-2 and semicircle orifice 3-3 around the circular arc of bayonet socket; The draw-in groove 1-1 corresponding matching on bayonet socket 3-1 and swinging axle top; Circular hole around the circular arc of bayonet socket and semicircle orifice cooperate with cylinder 2-2 above the gland; Button 4 cooperates with blind hole above the disk of swinging axle top, and the bottom of button is provided with a radial direction through hole 4-1, is provided with compression spring 5 between the bottom of the lower end of button and blind hole; Drive link 6 passes the through hole of gland both sides, the bar hole of swinging axle both sides, the radial direction through hole of button bottom connects as one the three; Swinging axle cooperates with the middle and lower part of cylindrical shell 9 by bearing 7 and 8, and the periphery of gland and the top of cylindrical shell are slidingly matched; Fixedly connected with shift fork 11 by alignment pin 10 in the bottom of swinging axle, shift fork and the contact both sides that is engaged in the roller 14 of eccentric shaft 13 front ends in the handle sleeve 12.
