Abstract
The utility model discloses an artificial knee joint, including the knee joint body, the knee joint body includes prosthese and lower prosthese, going up the prosthese and being provided with the knee down between the prosthese and alternately guide the subassembly, this knee alternately guides the subassembly and includes upward ligament of a lower ligament and two, be provided with the acetabular bone groove down on the prosthese, go up be provided with on the prosthese two with the false body plush copper of acetabular bone groove looks adaptation, it passes through false body plush copper, acetabular bone groove and knee and intersects and guide the subassembly and coordinate swing joint to go up prosthese and prosthese down. This artificial knee joint goes up prosthese and prosthese down and passes through false body plush copper, acetabular bone groove and knee and intersect and guide subassembly cooperation swing joint, goes up ligament and ligament down and is to intersect to describe and arranges at last prosthese under and between the prosthese, can not only link together the artificial joint, and stability is stronger in addition, guides and makes good use of.
Description
Technical field
The utility model is related to human body knee joint technical field, specially a kind of artificial knee joint.
Background technology
Human body knee joint is by thigh or makes femur, the shin bone of focile and fibula, kneecap constitute.In femur and shin
There is cartilaginous opereulum between bone, be referred to as medial meniscus and lateral meniscus.The front lower end of femur has groove properly to lay kneecap, these
The surface in joint covers cartilage, can absorb vibrations and bear pressure.It is that human body is most easily injured in motion that cartilage is particularly meniscus
Part, once joint injury, will result in arthralgia, dysfunction, prosthetic replacement can effectively rebuild joint work(
Can, improve the quality of life of patient.Ligament belongs to dense connective tissue.Can be divided mainly into two classes：Elastic connective tissue and collagen
The irregular dense connective tissue that fiber is interlaced with one another.Elastic fibrous tissue is the dense connective tissue based on elastomer.
Thick elastomer or bunchy arranged in parallel, such as ligamentaum nuchae and ligamentum flavum.The connective tissue of ligament white banding, matter is tough and tensile,
It is flexible, bone can be linked together, ligament is flexible, fibroid dense connective tissue.What it was attached to bone can
Movable part, but its scope of activities is limited in order to avoid damaging.Ligament connects bone and bone, and with respect to tendon connection is bone and muscle.Mesh
Before, the guidance function of existing artificial knee joint is poor.
Utility model content
The purpose of this utility model is to provide a kind of artificial knee joint, to solve above-mentioned background technology in propose ask
Topic.
For achieving the above object, the utility model provides following technical scheme：A kind of artificial knee joint, including knee joint sheet
Body, the knee joint body includes upper pseudocolloid and lower pseudocolloid, and knee friendship is provided between the upper pseudocolloid and lower pseudocolloid
Fork guidance kits, the knee intersects guidance kits and includes an inferior ligament and two arnold ligaments, and on the lower pseudocolloid hip is provided with
Mortar groove, is provided with two prosthese plush coppers being adapted with acetabular bone groove, the upper pseudocolloid and lower pseudocolloid on the upper pseudocolloid
Guidance kits are intersected by prosthese plush copper, acetabular bone groove and knee and coordinates flexible connection.
Preferably, the inferior ligament is S-shaped is arranged in the acetabular bone groove of lower pseudocolloid, between two prosthese plush coppers
Gap is left, two arnold ligaments are located in the gap, and one end of two arnold ligaments is fixedly connected with pseudocolloid in gap
On outer surface, the other end of two arnold ligaments is fixedly linked respectively with the two ends of inferior ligament.
Preferably, the arnold ligament and inferior ligament is cross-shaped is arranged between pseudocolloid and lower pseudocolloid.
Preferably, the outer surface of the upper pseudocolloid and lower pseudocolloid is smooth shape.
Compared with prior art, the utility model has the advantages that：The artificial knee joint, upper pseudocolloid and lower vacation
Limbs intersect guidance kits and coordinate flexible connection, arnold ligament and the cross-shaped row of inferior ligament by prosthese plush copper, acetabular bone groove and knee
Cloth can not only link together artificial joint between upper pseudocolloid and lower pseudocolloid, and stability is stronger, guidance function
It is good.
Description of the drawings
Fig. 1 is the utility model structural representation.
In figure：1 knee joint body, pseudocolloid on 101,102 times pseudocolloids, 2 gaps, 3 knees intersect guidance kits, under 301
Ligament, 302 arnold ligaments, 4 acetabular bone grooves, 5 prosthese plush coppers.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Fig. 1 is referred to, the utility model provides a kind of technical scheme：A kind of artificial knee joint, including knee joint body 1,
Knee joint body 1 includes that upper pseudocolloid 101 and the outer surface of lower pseudocolloid 102, upper pseudocolloid 101 and lower pseudocolloid 102 are
