Abstract
A crown protector for femur head is composed of a sleeve with a flange at its enclosed end and more than one through hole on its surface, a hollow cylinder with through holes on its surface and extended from said enclosed end of said sleeve, and an open encasing with a rib ring extended inward for matching with said sleeve. During the growth of femur after operation the newly grown blood vessels and callus can pass through said holes, so binding the sleeve with femur tightly.
Description
Technical field
The present invention relates to a kind of crown femoral head protector or femoral head surface replacement device, abbreviation " crown head "; relate in particular on a kind of femoral head that can directly be linked in after operation is cut; make it unlikelyly be subjected to extraneous wearing and tearing, and the device that can be combined into one with femur.
Background technology
At present, for the processing mode of hip joint disease, generally be with whole neck of femur along the smooth excision in neck of femur lower edge, and then handle artificial hip joint handle implanted femur pulp cavity will be arranged.But existing operation device is except existing fixing the coating the unsettled shortcoming, more because the blood vessel and the callus that newly grow can't coat the artificial hip joint handle effectively, thereby cause the artificial hip joint handle can't be fully and femur be combined into one, and then cause femur and artificial hip joint handle to meet with stresses shield and produce all inevitable complication, on practicality, have a greatly reduced quality, increase patient's misery.Above many disadvantages is perplexing medical dealer and patient for a long time always.
Existing operation device please refer to shown in Figure 1: it is a kind of artificial hip joint of femoral head surface replacement, it comprises a head 100, this head 100 has a slick spherical surface, and is recess in this head 100, in addition, this head 100 is provided with an outward extending cone 110 being the recess center position, and this head 100 is in recess, and this device construction can be inserted cone 110 in the femur in use, head 100 is linked on the surface of neck of femur, and fixes with bone cement.In the course of time, cause loosening, displacement easily even cause fracture of femoral neck and all other inevitable complication, and need operation once more to overhaul.Thereby on practicality, have a greatly reduced quality, increase patient's misery.Above many disadvantages is perplexing medical dealer and patient for a long time always.
Summary of the invention
Technical problem to be solved by this invention provides firm firm being coated and fixed of a kind of femoral head that makes disease, and the crown femoral head protector that can be combined into one with blood vessel that newly grows and callus.
In order to solve the problems of the technologies described above, the present invention has adopted following technical proposals: a kind of crown femoral head protector is provided, and it includes:
One sleeve, on the femoral head behind this sleeve fit Rhizoma Atractylodis Macrocephalae, this sleeve blind end periphery is provided with an outward extending flange, and this sleeve surface is provided with the hole that runs through more than wherein;
One cover body, its buckle are on sleeve, and described cover body is provided with an opening, and this opening just can enter for sleeve, and this cover body certain place is provided with the gilled rings that extends internally in the distance center position, this gilled rings just can with the mutual buckle of sleeve;
One cylinder is integral with sleeve or cover body and is connected, and is extended to the open end by blind end.
During use; can earlier cover body be nested on the sleeve; to there be the femoral head of pathological changes to cut into just again and can be sleeved on telescopic shape by operation; on femur, get out simultaneously the perforation of an appropriate depth; sleeve just can be linked on this femoral head after cutting; and make cylinder can penetrate in the perforation; thereby go deep in the femur, so that the postoperative femur can be because of the protection of cover body, unlikely being worn; and blood vessel that newly grows in the femur and crust scar can be passed hole and be grown in it; and sleeve can be combined into one with femoral head, and then make sleeve unlikely loosening, like this; not only can make sleeve firm firm on femoral head, and can protect that this femoral head is unlikely to come to harm again.
Further, described sleeve buckle in cover body an end and cover body between form a space, this space can be used for burying underground artificial bone meal or the other biological preparation that is used to promote femoral growth, during use, quicken femur and grow blood vessel and crust scar, pass hole and cover body and sleeve after, go deep in the artificial bone meal tissue again, And combines, finishes biological fixation.

The specific embodiment
See also shown in Fig. 2,3: crown femoral head protector of the present invention, comprise: a sleeve 10, be a circular sleeve shape in the present embodiment, this sleeve 10 is closed one end periphery and is provided with an outward extending flange 11, and these sleeve 10 surfaces are provided with more than one sleeve hole 12, these some sleeve holes 12 all run through sleeve 10, and in addition, this sleeve 10 is provided with one by the cylinder 13 of blind end to the open end extension; This cylinder 13 can be hollow or solid two kinds, this cylinder 13 can protrude outside the sleeve 10, when if this cylinder 13 is hollow, can be provided with some hollow cylinder holes 131 (as shown in Figure 3) on it, be nested with a cover body 20 on the described sleeve 10, be a hollow sphere in the present embodiment, this cover body 20 is provided with an opening 22, this opening 22 just can enter for sleeve 10, and certain place is provided with the gilled rings 21 that extends internally to this cover body 20 in the distance center position, this gilled rings 21 just can with the flange 11 mutual buckles of sleeve 10.
As shown in Figure 4 be the compound section sketch map of another specific embodiment of crown femoral head protector of the present invention: wherein cylinder 13 is located at the middle part of cover body 20 and is extended to opening part; and be integral with cover body 20 and be connected; the blind end of described sleeve 10 is provided with a hole that can allow cylinder 13 pass; described cylinder 13 is provided with screw thread; thereby can cylinder 13 and sleeve 10 pins be lumped together by bolt 132, described cylinder 13 is solid.
As shown in Figure 5 be the compound section sketch map of a specific embodiment again of crown femoral head protector of the present invention: its connected mode and basically identical shown in Figure 4; wherein; cylinder 13 is a hollow; can be provided with some hollow cylinder holes 131 on it, described cylinder 13 also closes by second bolt, 133 pins with cover body 20.
During use, please refer to shown in Fig. 6,7, earlier with the mutual buckle of cover body 20 by gilled rings 21 and flange 11, thereby buckle is on sleeve 10.And the femur powder 40 that can promote femur 30 growth is embedded in the space of 20 of sleeve 10 and cover bodies; to there be the femoral head 30 of disease to be processed into the shape that matches with sleeve 10 by the operation cutting; simultaneously; on femoral head 31, bore perforation 32 in the dark and femur 30 with instrument; cylinder 13 can be inserted in the perforation 32; thereby on the femoral head 31 that sleeve 10 can be linked in cut; so; not only can make on the firm firm femoral head 31 that is linked in postoperative of sleeve 10; and because the protection of cover body 20 makes this femoral head 31 avoid coming to harm once more.Further,, thereby sleeve 10 and cover body 20 can be combined into one, this cover body 20 be unlikely the loosening situation that breaks away from takes place with femur 30 because femur powder 40 can promote angiogenic growth and the molding of crust scar in the femoral head 31, and makes it pass hole 12.
