Abstract
The utility model relates to a medical flexible shaft transmission grinding handle, comprising a handle sleeve, a furcation connecting part matched and connected inside the handle sleeve through a plurality of bearings, a grip sleeve and a spring grip inside the grip sleeve. The utility model is characterized in that: a flexible shaft is joined between the furcation sleeve and the spring grip, a syphon is sleeved outside the flexible shaft, the smallest curvature radius R of the syphon is 150 mm; a metal hose is positioned between the flexible shaft and the inner wall of the syphon, a gap is kept between the metal hose and the flexible shaft. The utility model has the advantages that: by adopting the flexible shaft as the standard piece, the processing difficulty is reduced greatly, so as to reduce the cost; as the hose arranged between the flexible shaft and the syphon sleeve, the flexible shaft is protected and the service life is prolonged; the performance is reliable during the high-speed rotation and the noise is low.
Description
Technical field
This utility model relates to medical apparatus and instruments, is specifically related to medical flexible axle transmission mill handle.
Background technology
When performing an operation to patient, use the mill handle of straight-bar can influence doctor's sight line, therefore, the doctor likes using the mill handle at certain inclination angle, and this mill handle adopts bevel-gear sett to realize having mutually the transmission of power of the diaxon of certain angle usually.And medical mill handle requires to work under 30000-40000 rev/min rotating speed, and the bevel gear of straight-tooth or helical teeth can not meet the demands, and needs can meet the demands with the curved surface bevel gear.Adopt curved surface Bevel Gear Transmission structure not only to have baroque defective, but also have requirement on machining accuracy height, defective that difficulty is big, its production cost is also corresponding to be increased.Therefore, the existing mill handle of curved surface Bevel Gear Transmission structure that adopts need be improved.
Summary of the invention
The purpose of this utility model provides a kind of medical flexible axle transmission mill handle, and its drive mechanism is simple, makes easily, and production cost is low, dependable performance when high speed rotating, and noise is little.
Medical flexible axle transmission mill handle described in the utility model, comprise the handle sleeve and by be connected within it fork-shaped connector of bearing, chuck sleeve pipe and establish within it collet, it is characterized in that: between fork-shaped connector and collet, be connected with flexible axle, be with a bend pipe in the outside of flexible axle; The radius of curvature R minimum of bend pipe is 150mm.Flexible axle selection standard spare, the minimum diameter of flexible axle is 3.3mm in the existing standard, its minimum profile curvature radius R is 150mm, so the radius of curvature R minimum of bend pipe is 150mm.As select the bigger flexible axle of diameter, the corresponding increase of its minimum profile curvature radius for use.
Described medical flexible axle transmission mill handle is provided with metal hose between the inwall of flexible axle and bend pipe, maintain the gap between metal hose and the flexible axle.To reduce wearing and tearing, the protection flexible axle increases the service life, and reduces noise simultaneously.
Described medical flexible axle transmission mill handle, the last connecting screw rod of its flexible axle is connected with an end of fork-shaped connector; The following connecting screw rod of flexible axle is connected with an end of collet, which is provided with needle bearing.
Described medical flexible axle transmission mill handle, its upper end that is enclosed within the bend pipe of flexible axle outside is provided with ring washer, is connected by the telescopic end of first locking nut and handle, and the lower end of bend pipe is connected with the telescopic end of chuck by second locking nut.
Described medical flexible axle transmission mill handle is respectively equipped with the adjustment packing ring at the two ends of bend pipe, to regulate the length of metal hose, makes its contact good.
This utility model compared with prior art has the following advantages: the flexible axle of employing is a standard component, and difficulty of processing is significantly reduced, and has reduced cost; Between flexible axle and curved sleeve pipe, metal hose is set, has protected flexible axle, thereby prolonged service life; Dependable performance when high speed rotating, noise is little.
