Abstract
The utility model relates to an artificial joint half-hip two active head device belonging to the field of the clinic medical device and has the composition that an inner lining and a ball head are arranged in a ball cup which is provided with a concave groove inside, a notch and two clamping holes are arranged on a clamping ring whose outside diameter end is provided with a rectangular clamp, and the clamping ring can be locked firmly after being clamped by the rectangular clamp in the concave groove of the ball cup to prevent the ball head and the inner lining from loosening or falling. Compared with the prior art, the utility model has the advantage of simple and reasonable structure, and convenient manufacture and use.
Description
What this utility model was related is medical clinical device field.Be specially adapted to artificial joint half hip double motion head parts.
In the prior art, artificial joint is applied in medical industry clinical already, for example the composition of half hip double motion head artificial joint is that parts such as ball cup, liner, bulb and pressure ring are formed, and its structure can be with reference to the accompanying drawings shown in 1, and given in accompanying drawing 1 is the structural representation of half hip double motion head artificial joint in the prior art, 1 is the ball cup in accompanying drawing 1,2 is liner, and 3 is bulb, and 4 is pressure ring, 5 is joint handle, and 6 use the hole for screw thread applies.This structure is that pressure ring 4 is fixed on liner 2 and bulb 3 in the ball cup 1 by being threaded of ball cup 1, and the bulb 3 of double motion head artificial joint adopts the conical surface to be connected with joint handle.The work process of this device is, behind double motion head artificial joint and the implanted human body of joint handle one, people's thigh drives the joint handle motion, there is not relative motion between joint handle and the bulb, only be that bulb rotates in liner, when rotational angle arrived certain limit greatly, the rotational angle of bulb will be greater than its maximum rotation angle at inside liner, and this moment, joint handle and bulb just forced the spherical outside surface in whole double motion head joint also to rotate in the mortar of the pelvis of human body.The shortcoming of this device is, because bulb relatively rotates with liner and pressure ring, and the direction of rotation is controlled by the human body leg exercise, so be unascertainable.Therefore when bulb rotation direction and pressure ring be threaded into direction when opposite, just pressure ring might be screwed out gradually, the function of this device was thoroughly lost efficacy.The artificial joint of another kind of double motion head in the prior art can 2 be narrated with reference to the accompanying drawings, and 1 is the ball cup in accompanying drawing 2, and 2 is liner, 3 bulbs, 4 is snap ring, and 5 is folder hole, and 6 is otch, and 7 is liner inclined-plane card, 8 is ball cup groove, and 9 is the liner groove, and 10 is the snap ring rectangular card.The structure of this device is that a circle groove 8 is arranged in ball cup 1, at place, liner outer one circle inclined-plane card 7 is arranged, one circle groove 9 is arranged, have otch 6 at snap ring 4 end faces at the liner inner surface, have the folder hole 5 that 2 special-purpose hand vice insert on the otch 6 both sides end faces, on snap ring 4 external diameters, snap ring rectangular card 10 is arranged.This Unit Installation is with liner 2 disposable being pressed in the ball cup 1, and it is firm in ball cup groove 8 by liner inclined-plane card 7 cards, again bulb 3 is put into liner 2, insert folder hole 5 with special-purpose hand vice then, and inwardly compress snap ring 4, and make the internal diameter of its external diameter less than liner 2, after being put into liner 2, snap ring 4 unclamps special-purpose hand vice, under snap ring 4 elastic reactions, the snap ring rectangular card is embedded in the liner groove 9.The major defect of this device is: therefore the sterilization before can't undergoing surgery to the ball cup of this artificial joint and liner slit before clinical operation can only require this product is processed and offer hospital under aseptic condition.
Order of the present utility model is that proposition is a kind of simple in structure, and is reasonable, and makes things convenient for the double motion head artificial joint device of clinical manipulation.
By the double motion head artificial joint device that the purpose of this utility model proposed, can 3 be described in detail with reference to the accompanying drawings.Accompanying drawing 3 is generalized sections of this utility model double motion head artificial joint apparatus structure, and 1 is the ball cup in accompanying drawing 3, and 2 is liner, and 3 is bulb, and 4 is snap ring, and 5 is folder hole, and 6 is otch, and 7 is the snap ring rectangular card, and 8 is ball cup groove.The composition of the two moving worker's joint arrangements of this utility model is that liner 2 is housed in ball cup 1, bulb 3 is housed in liner 2, one circle Baltimore groove 8 is arranged in ball cup 1 inboard, being at the planar end surface of snap ring 4 has otch 6, on two planar end surfaces of otch 6, have 2 folder holes 5, the aperture that it is characterized in that each folder hole 5 on snap ring 4 should be greater than the 0.1-1.0mm of the point diameter of general surgical hemostasis pincers, and the snap ring rectangular card 7 on snap ring 4 external diameter ports should be stuck in the ball cup groove 8 on ball cup 1 inboard.Its installation method is to insert folder hole 5 and inside cramping with mosquito forceps, because dwindling of otch 6, the external diameter that makes snap ring 4 is less than ball cup 1 mouth diameters, snap ring is put into the ball cup and unclamped mosquito forceps, 4 of snap rings return to life size, therefore the snap ring rectangular card 7 on the snap ring 4 is embedded in the ball cup groove 8 in the ball cup 1, and at this moment the liner ball cup 1 in 2, bulb 3 are all firm by snap ring 4 locks.
This utility model double motion head artificial joint has simple and reasonable compared with prior art, and it shows:
1, compare safer with first kind of structure.Under the effect of human body shank, bulb has the power that is pulled outwardly.The internal ring circle of snap ring is a sphere that coincide with spherical surface, and when bulb pulled outward, the inner and outer diameter of snap ring had the trend that becomes big.Because the constraint of ball cup has limited the increase of snap ring overall diameter, has guaranteed that bulb can not take off, the probability of having avoided above-mentioned first kind of structure pressure ring to screw out.
2, compare with above two kinds of structures, the installation and removal of this structure double motion head do not need specific purpose tool, only need once can mosquito forceps.Mosquito forceps is general utility tool in hospital operating room.This structure not only can offer hospital with disinfection, does not need to sterilize once more when operation, and can offer hospital with non-disinfection.Wider than second kind of structure scope of application.When this structure double motion head offers hospital with non-disinfection, in hospital, parts can be taken apart, so that carry out disinfection before the operation.Promptly all parts are dismountable.
