Abstract
The utility model relates to an extendable regulation type artificial joint prosthesis used for a patient who uses an artificial limb. Because of growth and development, when the relative heights of a healthy limb and an artificial limb differ greatly, and the patient is difficult to walk, the technology divides an integral artificial joint into two stages that are an articular end and a broach end, and a regulating screw is arranged between the articular end and the broach end. Both ends of the regulating screw and the articular end and the broach end are in thread connection, and the middle part of the screw is provided with a regulating screw hexagonal nut fixedly connected with the screw. The regulating screw hexagonal nut divides the screw into a right section and a left section of positive and negative threads. A locking nut of the articular end and the regulating screw of a locking nut of the broach end are in positive and negative thread match. The utility model solves the problem that the past fixing integral artificial joint is inconveniently to adjust the length, and the utility model can slightly adjust the length of the artificial limb for many times according to the developmental condition of the healthy limb, does not influence the physiological function of the limb bone, and also saves medical expenses.
Description
Technical field
This utility model relates to a kind of invalid adjustable type artificial joint prosthesis that prolongs that fits an artificial limb, and belongs to the shaping surgery technology field.
Background technology
Limbs are suffered from the patient of tumor, Ipsilateral is equipped with artificial limb after operation, and the speed of growth ratio of strong side limbs fits an artificial limb adnation length soon, and substitution worker Joint orthosis one side is shorter relatively, can't normally walk, in the time of can only waiting until to a certain degree, change another pair artificial joint prosthesis, if patient is child, the artificial joint that will renew at any time along with the growth promoter of health, painful big, the expense height, this is a problem anxious to be solved at present.
Summary of the invention
The purpose of this utility model is that the problem at present existence provides a kind of artificial limb the invalid adjustable type artificial joint prosthesis that prolongs, its structure as shown in Figure 1, original artificial joint is whole, joint end (1) and broach end (5) are arranged, broach end (5) connects broach (7) and has located reinforcing sleeve (6), the applicant is divided into two sections with the artificial joint of integral body, joint end (1) and broach end (5), there is adjusting screw(rod) (8) centre, the two ends of adjusting screw(rod) (8) and joint end (1) and broach end (5) are to be threaded, and go up near articulation (1) at adjusting screw(rod) (8) and install joint end locknut (2), at the nearly broach end (5) of adjusting screw(rod) (8), install broach end locknut (4) and in the middle of adjusting screw(rod) (8), connecting adjusting screw(rod) hex nut (3), screw thread on the screw rod (8) is positive left-hand thread from adjusting screw(rod) hex nut (3) punishment, go up near articulation (1) at adjusting screw(rod) (8), install joint end locknut (2), nearly broach end (5) is installed broach end locknut (4), two locknuts (2,4) screw thread is opposite.
When needs prolong artificial joint, earlier with removing the nut (2,4) that son unclamps joint end (1) and broach end (5), rotate the adjusting screw(rod) hex nut with removing son then, screw rod (8) withdraws from from joint end (1) and broach end (5) female thread, and whole artificial joint prolongs to be adjusted to and gets final product when suitable with strong limb height.With removing son two locknuts (2,4) are locked respectively.
This utility model has solved the problem that the artificial joint prosthesis that is fixed as one can not be regulated length, can only open an osculum is that the available son of removing is regulated the length that prolongs artificial limb, can repeatedly regulate in a small amount, can not influence the physiological function of the skeleton of limbs, also save medical expense.

The specific embodiment
Material of the present utility model is a titanium alloy, artificial joint is made two-part, joint end (1) and broach end (5), middle joint car has the female thread that matches with adjusting screw(rod) (8), earlier adjusting screw(rod) (8) is screwed into joint end (1) and broach end (5), again it is screwed into the other end, adjusting screw(rod) (8) is from being fixed on the intermediary hex nut of adjusting screw(rod) (8) (3) boundary, two ends are positive left-hand thread, joint end locknut (2) and broach end locknut (4) also are positive left-hand threads, above two locknuts will be locked respectively after appropriate to installing.
Claims (2)
1, a kind of adjustable type artificial joint prosthesis that prolongs comprises joint end (1) and broach end (5), and broach end (5) connects broach (7) by reinforcing sleeve (6), it is characterized in that artificial joint is divided into two sections, and promptly joint end (1) is one section; Broach end (5) is another section, there is the female thread that matches with intermediate regulations screw rod (8) this end of two sections, the screw thread that is connected with in the middle of the adjusting screw(rod) (8) on adjusting screw(rod) hex nut (3), the screw rod (8) is positive left-hand thread from adjusting screw(rod) hex nut (3) punishment, go up near articulation (1) at adjusting screw(rod) (8), install joint end locknut (2), nearly broach end (5) is installed broach end nut (4), and the screw thread of two nuts (2,4) is opposite.
2, the adjustable type artificial joint prosthesis that prolongs according to claim 1, it is characterized in that making the material that this utility model adopts is titanium alloy.
