The meaning of "plurality" is two or more unless specifically limited otherwise.
To alleviate the pain of a patient with an implanted humeral prosthesis, the present invention provides an extendable humeral prosthesis according to fig. 1-3, comprising: the humerus upper end prosthesis comprises a humerus upper end body 1 and a broach prosthesis 2 which is sleeved and connected with the humerus upper end body 1; particularly, the upper end of the broach prosthesis 2 is sleeved on the lower part of the upper humerus body 1;
specifically, the structure of the humerus upper end body 1 is consistent with the physiological upper end of the femur.
In order to enhance the connection stability of the upper humerus body 1 and the broach prosthesis 2, a bar-shaped fixing groove 21 is formed in the upper portion of the broach prosthesis 2 along the length direction of the upper humerus body, and a pin hole 11 is formed in the lower portion of the upper humerus body 1, so that a fixing pin 3 is sequentially inserted into the pin hole 11 and the bar-shaped fixing groove 21 to connect and fix the upper humerus body 1 and the broach prosthesis 2. More specifically, the specific position of the pin hole 11 for abutting against the strip-shaped fixing groove 21 of the broach prosthesis 2 may be determined according to the length of the desired prosthesis, and finally, the fixing pin 3 is inserted into the pin hole 11 and the strip-shaped fixing groove 21 to fixedly connect the upper humeral end body 1 and the broach prosthesis 2. And then the problem that the limbs of the two-way patient are unequal in length in the prior art is solved.
In a specific embodiment, in order to facilitate the adjustment of the length of the prosthesis, the structure of the invention further comprises an adjusting screw 4, wherein an annular groove 41 is formed on the upper part of the adjusting screw 4 along the circumferential direction of the adjusting screw, and a limit hole 12 is formed on the upper part of the upper humerus body 1;
an insertion cavity 22 is formed in a portion, sleeved with the humerus upper end body 1, of the broach prosthesis 2 along the length direction, so that the adjusting screw 4 is inserted into the insertion cavity 22 from the upper portion of the humerus upper end body 1, then abuts against the annular groove 41 through the limiting hole 12 via the limiting pin 5, the adjusting screw 4 is used for fixing, and meanwhile, the connection stability of the humerus upper end body 1 and the broach prosthesis 2 is enhanced.
In the specific embodiment, in order to adjust the length of the prosthesis according to the requirement more conveniently, the adjusting screw rod 4 is provided with external threads along the length direction, the insertion cavity 22 is internally provided with an internal thread which is matched with the external thread, when the length of the prosthesis needs to be adjusted, because the limit pin 5 is propped against the annular groove 41 on the adjusting screw rod 4, the adjusting screw rod 4 cannot move in the up-down direction, due to the thread structure, the broach prosthesis 2 can be driven to move downwards when the broach prosthesis is rotated, meanwhile, the fixing pin 3 is pushed into the strip-shaped fixing groove 21 of the broach prosthesis 2, so that the broach prosthesis 2 cannot rotate per se and can only move up and down, thereby achieving the purpose of prolonging the prosthesis, the design of the prosthesis structure ensures that the opening is small, the bleeding is less, the operation risk is small in the process of extending the prosthesis, and the patient can pass through the prosthesis, especially children in the growth period.
In a specific implementation, the external thread is located below the annular groove 41 on the adjusting screw 4, so that the adjusting screw 4 does not move up and down during the extension of the prosthesis, and the connection stability with the upper humerus body 1 is maintained.
In a specific embodiment, in order to adjust the length of the prosthesis conveniently, a screwing hole 42 is formed in the top of the adjusting screw rod 4, the adjusting screw rod 4 is screwed into the broach prosthesis 2 through the screwing hole 42, specifically, the adjusting screw rod 4 is controlled to rotate by an auxiliary tool through the screwing hole 42 so as to adjust the position of the broach prosthesis 2 relative to the upper humeral end body 1, further, the screwing hole 42 is a hexagonal hole, and an inner hexagonal wrench is used to rotate the adjusting screw rod 4.
More specifically, the broach prosthesis 2 is composed of an insertion section 23, a middle section 24 and a connection section 25, wherein the insertion cavity 22 and the strip-shaped fixing groove 21 are both arranged on the connection section 25, the strip-shaped fixing groove 21 is not connected with the insertion cavity 22, and the diameter of the connection section 25 is smaller than that of the middle section 24 and larger than that of the insertion section 23. The upper humerus body 1 is provided with a containing cavity 13 for containing the broach prosthesis 2 at the lower part and a working cavity 14 communicated with the top of the containing cavity 13 at the upper part, and is used for auxiliary tools to enter from the working cavity 14 and be connected with the adjusting screw rod 4 so as to adjust the length of the prosthesis. Further, the accommodating chamber 13 and the working chamber 14 are concentric.
The assembly steps of the structure of the invention are as follows:
screwing an adjusting screw rod 4 into the intramedullary pin prosthesis 2 through an inner hexagonal wrench, inserting an assembly of the adjusting screw rod 4 and the intramedullary pin prosthesis 2 from the bottom of the upper humerus body 1, inserting a limiting pin 5 from a pin hole 11 on the upper humerus body 1 to be matched with an annular groove 41 on the adjusting screw rod 4, and welding the limiting pin 5 and the upper humerus body 1 firmly from the outside;
the fixing pin 3 is inserted into the limit hole 12 on the upper humerus body 1 and is welded firmly, and the assembly of the structure of the invention is completed.
The adjustable screw rod 4, the upper humerus body 1 and the broach prosthesis 2 can be molded through 3D printing.
The structures or the using principles which are not explicitly described in the invention are all realizable by the conventional technical means in the field, and therefore, the details are not described.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
