In chinese patent 2020104704042, a distal humerus prosthesis is disclosed, the distal humerus body of which can be specifically made of titanium alloy powder by 3D printing technique; the marrow needle can be made of forged titanium alloy by machining, and can be standardized, namely, a plurality of specifications are prepared in advance, and the corresponding specifications are selected according to the diameter of the diaphysis of the humerus of a patient; the distal humerus body is provided with a cylindrical connecting part, the intramedullary pin is provided with a corresponding intramedullary pin connecting part, the cylindrical connecting part is connected with the intramedullary pin connecting part in a cone-fit way, and the cylindrical connecting part and the intramedullary pin connecting part are connected into a whole through a frustum-shaped convex cone and a frustum-shaped concave cone.
The humerus distal prosthesis can only solve the problem that the tumor prosthesis can only be installed after osteotomy, and the loss is excessive Huang Jingu, so that the operation time is increased and the pain of a patient is aggravated.
Disclosure of Invention
The utility model aims to provide a distal humerus joint surface prosthesis which is designed according to the joint surface matching of a patient, can wrap residual bone, can be implanted without osteotomy, can solve various symptoms such as arthritis, comminuted fracture and the like, retains more golden bones, greatly saves operation time and relieves pain of the patient.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
the distal humerus joint surface prosthesis comprises a marrow needle and a joint surface prosthesis, wherein the marrow needle is connected with the joint surface prosthesis through a herringbone structure, two bifurcation ends of the herringbone structure are fixedly connected with the joint surface prosthesis, and a converging end of the herringbone structure is connected with one end of the marrow needle; the herringbone structure is a bone trabecula porous structure, and the outer surface of the herringbone structure is provided with a suture ring for fixing human soft tissues.
Further, the herringbone structure and the marrow needle are of an integrated structure.
The utility model has the beneficial effects that:
1. the herringbone structure contacted with the bone is designed to be a bone trabecular porous structure, so that the later-stage stability of the prosthesis is greatly improved.

4. No need of osteotomy in operation, more Huang Jingu are reserved, the operation time is greatly saved, and the pain of patients is relieved.
Drawings
FIG. 1 is a schematic diagram of an embodiment of the present utility model;
1. a marrow needle, 2, a suture ring, 3, a herringbone structure, 4 and a joint surface prosthesis.
Detailed Description
The following description of embodiments of the present utility model will be made more fully hereinafter with reference to the accompanying drawings and examples, in which embodiments, however, are shown in the drawings, in which embodiments of the utility model are shown, in which some, but not all embodiments of the utility model are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The distal humerus joint surface prosthesis comprises a marrow needle and a joint surface prosthesis, wherein the marrow needle is connected with the joint surface prosthesis through a herringbone structure, two bifurcation ends of the herringbone structure are fixedly connected with the joint surface prosthesis, and a converging end of the herringbone structure is connected with one end of the marrow needle; the herringbone structure is a bone trabecula porous structure, and the outer surface of the herringbone structure is provided with a suture ring for fixing human soft tissues.
Further, the herringbone structure and the marrow needle are of an integrated structure.
The following is a more specific example:
(1) The intramedullary pin 1 is a herringbone intramedullary pin, is inserted into the intramedullary cavity to play a role in stabilizing, can adjust the length of the intramedullary pin according to the residual condition of the intramedullary cavity of a patient, and is designed to be herringbone to increase the anti-rotation effect;
(2) The suture ring 2 can suture and bind surrounding soft tissues and free bones to play a role in fixation, and can be removed by a pair of locking pliers if the influence is removed during operation;
(3) The herringbone structure 3 is a bone trabecula porous structure, which is beneficial to promoting bone ingrowth and soft tissue crawling;
(4) The joint surface prosthesis 4 is finished according to the anatomical structure design of a patient, and polishing treatment is carried out, so that elbow joint movement is recovered to the greatest extent.
The novel humerus prosthesis mainly aims at a humerus prosthesis of a specific patient, solves the problems that the humerus prosthesis needs more osteotomies and is easy to produce complications in the related art, reduces the burden of the patient, shortens the operation time of the prosthesis, reduces the pain of the patient, has a bone-trabecular porous structure on a bone contact surface, has good postoperative stability effect, better short-term and long-term functional prognosis, prints the prosthesis according to the bone of the patient, and has good joint mobility after operation.
The method comprises the following steps:
(1) And the porous structure of the bone trabecula is designed on the part contacted with the bone, so that the later-stage stability of the prosthesis is greatly improved.
(2) Can wrap the residual bone, can be implanted without osteotomy, and can solve various symptoms such as arthritis, comminuted fracture and the like.
(3) The whole prosthesis is 3D printed, and the prosthesis which is most matched with the prosthesis can be designed according to the physiological radian of the joint of each patient, so that the personalized customization is realized.
(4) No need of osteotomy in operation, more Huang Jingu are reserved, the operation time is greatly saved, and the pain of patients is relieved.
