Description

The ceramic-lined concussion extractor of artificial hip joint
Technical field
The present invention relates to medical instruments fields, and in particular to a kind of ceramic-lined concussion extractor of artificial hip joint.
Background technique
Artificial hip joint operation includes manual acetabulum displacement and artificial femoral head replacement, needs to use manual acetabulum (i.e. hip Mortar prosthese), acetabular component usually by acetabular cup and it is ceramic-lined form, acetabular cup is fixed on people by bone cement or porous coating It is ceramic-lined to be typically designed to be press-fitted locking with acetabular cup taper in body acetabular fossa, have be identical between the two, so that The problem of ceramic-lined to be not easy to fall off from acetabular cup, but this also brings ceramic-lined more difficult taking-up.
However, original prosthese need to be taken out in artificial hip joint revision procedure, takes acetabular component to be divided into two steps, first take out It is ceramic-lined in acetabular cup, then acetabular cup is removed from human body.
In clinical practice, it is common practice that be against liner edge with osteotome (chisel), osteotome tapped with tup, by liner It is taken out after shaking loose, it is big due to lacking positioning and tup percussion amplitude, often there is osteotome slippage, fluctuation of service, further, since outside Cup is bonded closely with liner, is tapped by artificial, is taken time and effort, seriously affect procedure efficiency, and tup knock, will increase trouble The uneasy sense of person.
Summary of the invention
For in the prior art, acetabular component liner takes out tool and lacks positioning, and operating difficulties is easy to the problems such as slipping, The invention proposes a kind of ceramic-lined concussions of artificial hip joint with good location, simple to operate, time saving and energy saving to take Device out.
To achieve the above object, the ceramic-lined concussion extractor of artificial hip joint proposed by the present invention, including work head end With for providing the power source of straight reciprocating motion；
The head end that works includes a vibrating arm, is coaxially provided with a positioning inner core in vibrating arm, positions top and the vibration of inner core Bar is connected by elastic element, and the bottom end for positioning inner core runs through the bottom of vibrating arm and is connected with a positioning ball；The top of vibrating arm End is fixedly connected with power source, and a percussion bar obliquely is fixed on the outside of vibrating arm, taps bar and vibration rod axis in pre- Clamp angle.
Preferably, in the ceramic-lined concussion extractor of artificial hip joint, the diameter and acetabular bone of the positioning ball Prosthese liner clearance fit, gap are 0.5mm~1mm.
Preferably, in the ceramic-lined concussion extractor of artificial hip joint, the elastic element is spring or gas Capsule.
Preferably, in the ceramic-lined concussion extractor of artificial hip joint, tap bar and vibrating arm in 30 °~ 60°。
Preferably, in the ceramic-lined concussion extractor of artificial hip joint, the power source includes outer housing, outside There is motor, driving gear, driven gear, first connecting rod, second connecting rod, sliding bar and linear bearing, motor passes through in shell Bracket is fixed on outer housing, and for driving driving gear to rotate, driven gear is engaged with driving gear, one end of first connecting rod It is fixed in the rotary shaft of driven gear, one end of the other end and second connecting rod is hinged, the other end and sliding bar of second connecting rod One end it is hinged, the other end of sliding bar is installed through the linear bearing on outer housing, and extends outer housing and vibrating arm Top be fixedly connected.
Preferably, in the ceramic-lined concussion extractor of artificial hip joint, the vibrating arm is connect with sliding bar Mode is to be detachably fixed connection.It is detachably fixed connection and uses the disassembly machinery fields routine such as be threadedly coupled, snap connection Connection type.
In use, first will positioning inner core inlay card in the ball groove of acetabular component liner, due to positioning inner core head end with Liner ball groove size fit, it is convenient to it realizes the positioning of extractor, while positioning formation ball-joint structure between inner core and liner, The centre of sphere that the work head end of extractor can position ball is freely rotated, to adjust the tilt angle of work head end.Then, work is adjusted The bottom end of percussion bar is made to be resisted against the upper limb anchor ring of liner as head end；Finally turn on the power source, drives vibrating arm by power source It moves back and forth, so that tapping bar constantly beats liner, so that the binding face of liner and acetabular cup be shaken loose, takes out liner.
Operating time has been saved so that liner taking-up operation is simpler convenient using the extractor proposed in the present invention, And reduce operation risk.
