Abstract
The utility model relates to an assembled buffer sessile hip joint and is in an elastic shock avoiding structural design which is composed of a femur end adjustable artificial head, a double-sheath type vertebra table capable of acting, a built-in buffer elastic shock avoiding device, a femur neck dissection shape outward built hollow prosthesis and a body double-lock fixing nail and is similar to cartilage tissue of the surface of the joint. The assembled buffer sessile hip joint is assembled by movement simulation machines according to the unique dissection relation, the physiology movement function and the characteristic of the biomechanics of the hip joint of a human body and has the characteristic of the simulation joint. The assembled buffer sessile hip joint has the advantages that the assembled buffer sessile hip joint simulates the physiology movement function of the hip joint and conforms to the characteristic of the biomechanics, the shock avoiding device decreases the hedging collision between joint movement surfaces and relieves the stress conduction, the joint buffer shock avoiding device can obviously reduces the friction index between the joint movement surfaces and prolongs the service life, and the unique conception and the assembled design can cause the operation to be simple and convenient and have strong adjustability.
Description
(1) technical field:
This utility model relates to a kind of orthopaedics artificial joint, particularly a kind of combined buffer-type stockless hip joint.
(2) background technology:
At present, orthopaedics is widely used with artificial joint, has solved the difficult problem of many orthopaedics patients.But existing artificial hip joint not buffering is not kept away the function of shaking, and causes to produce very stiff and demandingly to impulse force between articular prosthesis, and joint easy to wear raises the frictional index between joint motions face, reduces service life.In the artificial hip joint operation, also operation technique is complicated, and adjustability is poor.
(3) summary of the invention:
The purpose of this utility model is to design a kind of combined buffer-type stockless hip joint, and it is overcome above-mentioned shortcoming, is a kind of practical novel artificial joint.
The technical solution of the utility model: a kind of combined buffer-type stockless hip joint, it is characterized in that it is by the artificial bulb of adjustability, movable double-sleeve type slip vertebra platform, the buffering shock preventing device, the external neck of femur is dissected the shape hollow prosthesis and is reached fixedly pinning formation, cover and conical desk shape overcoat in said movable double-sleeve type slip vertebra platform comprises, interior cover is fixedlyed connected with external hollow prosthesis end, fixedly pinning places in the interior cover on the external hollow prosthesis according to the endoporus on the prosthese and suffers from limb neck of femur stump and fix, interior cover is outer to be the conical desk shape overcoat, place the fixedly pinning top end in the movable double-sleeve type slip vertebra platform to place the buffering shock preventing device, put movable pin hole in the movable double-sleeve type slip vertebra platform, the outer steady pin hole that put of movable double-sleeve type slip vertebra platform, the restriction pin penetrate in outside the steady pin hole that puts and in the movable pin hole that puts, the buffering shock preventing device is limited under the restriction pin; The artificial bulb of adjustability places the conical desk shape overcoat outward according to its conical desk shape endoporus and the outer tight fit assembling of conical desk shape overcoat; The external neck of femur is dissected to also have on the shape hollow prosthesis with fixing pinning and is cooperated localized other locking nail hole.
Above-mentioned said buffering shock preventing device is spring or other elastic component.
Above-mentioned said external neck of femur dissect have on the shape hollow prosthesis to cooperate localized other locking nail hole with fixing pinning be one or more.
Operation principle of the present utility model is: a kind of the design that is similar to articular surface cartilaginous tissue elasticity anti-vibration structure arranged by what the adjustable dummy head of femur end, movable double-sleeve type vertebra platform, built-in buffering elasticity shock preventing device, neck of femur dissected that shape external hollow prosthesis and body twin-lock staple form, it is anatomy relationship with the human hip uniqueness, physiological activity function and biomechanics characteristic thereof are basis, employing motion simulation machinery makes up and constitutes, and has the feature in emulation joint.
Superiority of the present utility model is: 1, emulation meets its biomechanics characteristic in the physiological movement function of hip joint; 2, shock preventing device has reduced the liquidating property collision between the joint motions face, the relieve stresses conduction; 3, buffering shock preventing device in joint can obviously reduce the frictional index between joint motions face, and prolong service life; 4, design is unique, and combined design can make operation technique simple, convenient, and adjustability is strong.
