Abstract
The utility model relates to medical equipment. An inner hole dilating drilling head for orthopedics, which comprises a hollow sleeve pipe, a movable shaft arranged in the sleeve pipe, a blade arranged at the end of the movable shaft, corresponding two sides on a pipe wall of the sleeve pipe are provided with strip-shaped holes, the movable shaft is arranged in the sleeve pipe through a dowel positioned in the strip-shaped holes, and the outer side of the sleeve pipe is sheathed with a handle. The blade is pivoted on the sleeve pipe through a rotary shaft and is connected with the end of the movable shaft by the other connective point, and the position of the sleeve pipe corresponding to the blade is provided with the strip-shaped holes. The utility model has the advantages of big work area and high efficiency, and a patient's pain can be reduced.
Description
This utility model relates to a kind of medical apparatus and instruments, the interior reaming bit that particularly a kind of orthopaedics is used.
Sometimes downright bad tissue is rejected in needing to have an operation bone when diseases such as treatment femur head necrosis, way commonly used is to punching on bone with chisel, then curet is put in the aperture slough is struck off, because scraper and drill bit all are straight, if the too little dead angle that just is easy to generate of working hole, slough under the dead angle is rejected unclean, if the quantity of the diameter of expansion working hole or increase working hole can increase patient's misery again, prolong the time of healing, on the other hand, because curet is manual operations, inefficiency.
The purpose of this utility model provides a kind of interior reaming bit of orthopaedics that can enlarge the work area of blade relatively.
For achieving the above object, this utility model adopts following technical scheme:
Orthopaedics described in the utility model with interior reaming bit comprise a hollow sleeve pipe, be installed in live axle in the sleeve pipe, be installed in the blade of live axle end, both sides corresponding on the telescopic tube wall have the strip hole, live axle is installed in sleeve pipe by the pin that is arranged in the strip hole, and the telescopic outside is set with handle; Blade is articulated on the sleeve pipe by a rotating shaft, and is connected with the end of live axle with another junction point, and the position that sleeve pipe is corresponding with blade has the strip hole.
As to further improvement of the utility model, described handle is one to be sleeved on the pipe on the sleeve pipe, and the inwall of this handle has the corresponding annular groove of length of its diameter and pin.
After adopting technique scheme, by lever operated live axle axially-movable, promptly can regulate blade rotates on pivot, the range of activity that makes point of a knife is greater than telescopic diameter, reach the purpose that enlarges work area, if this orthopaedics is installed on the motor with interior reaming bit, can also increase work efficiency.
Further specify this utility model below in conjunction with drawings and Examples:
Accompanying drawing is the longitudinal sectional view of an embodiment of the present utility model.
As shown in drawings, orthopaedics described in the utility model with interior reaming bit comprise a hollow sleeve pipe 1, be installed in live axle 2 in the sleeve pipe 1, be installed in the blade 3 of live axle 2 ends, both sides corresponding on the tube wall of sleeve pipe 1 have rectangular strip hole 4, live axle 2 is installed in sleeve pipe 1 by the pin 5 that is arranged in strip hole 4, the outside of sleeve pipe 1 is set with handle 6, handle 6 is one to be sleeved on the pipe on the sleeve pipe 1, the inwall of this handle 6 has the corresponding annular groove of length of its diameter and pin 5, and pin 5 just in time can be stuck in this groove.Blade 3 is articulated on the sleeve pipe 1 by a rotating shaft, and articulates with the end of another junction point and live axle 2, and sleeve pipe 1 and blade 3 corresponding positions have strip hole 7.
During use, this orthopaedics is installed on the motor with interior reaming bit, handle 6 upwards can not be pushed away when not needing blade 3 work, this moment, blade 3 can be fully retracted in the sleeve pipe 1; When handle 6 was pushed away downwards, blade was in rotation on the pivot and outside sleeve pipe 1 is stretched out in strip hole 7, and under the drive of motor, sleeve pipe 1 rotates synchronously with blade, with the tissue cutting-out of pathological changes.
