Abstract
The utility model discloses a fused thighbone handle of a thighbone, which consists of a connecting conical head, a nape, a handle body, a sliding lock groove, a connecting thread, a fixed medullar cavity rod, a pair of connecting screw nails and two pieces of metal reinforcing plates. The components are assembled to use, so that the fused thighbone handle is applied to the diseases such as the accidental thighbone split, the thighbone fracture, the thighbone coloboma and the like in the operation. The fused thighbone handle can fast connect the split or fractured thighbone, thereby furthest saving the operating time, leading a patient to be capable of preferably recovering the normal motion function of a human body, and prolonging the service life of the implanted prosthesis in the human body.
Description
Technical field
This utility model relates to a kind of femur pattern of fusion femoral stem, a kind of specifically novel, reliable, femoral stem that can at utmost be fixed in human femur under loading.
Background technology
Artificial hip prosthesis's replacement operation considerable time occurred.In the biotype hip replacement, because improper or human femur under loading form, the quality of operation technique femur splitting phenomenon occurs through regular meeting when prosthese is installed.At this moment just need carry out revision procedure and repair impaired femur, common method is for handling the femur binding with the titanium silk.This situation occurs, not only prolonged operating time, brought more misery, and delayed the cycle of postoperative rehabilitation to the patient.
The femur not good for sclerotin and the femoral bone cavitas medullaris form is short of behind the initial stage prosthetic replacement, has bigger probability prosthetic loosening to occur, need carry out revision procedure.This situation is inscrutable in stage now, can not avoid certainly.
How can make that hip prosthesis and femur are better to be combined, and also enough adhesions can be arranged, and then make postoperative rehabilitation fast, be difficult for prosthetic loosening and cause carrying out revision procedure for the not good femur of sclerotin.
Though some companies adopt the method that increases pulp cavity internal fixation bar, fix in distal femur, play the effect of fixing whole prosthese.But this kind design all is to overhaul the handle design mostly, seldom adopts for first replacement prosthesis, and adds fixed bar in the pulp cavity separately, can not solve the loosening problem of prosthese postoperative fully.
In sum, for safe and reliable, simple in structure at present, be connected firmly with femur, can change fixed form at any time, still there is very big demand in the femoral hip stem prosthese of implanting that is easy to perform the operation.
The utility model content
This utility model purpose is to remedy the backward situation of present technology in order to satisfy orthopedist's demand, and a kind of very easy easy-to-use femoral hip stem prosthese is provided.
In order to realize this utility model purpose, this utility model adopts following design:
A kind of femur pattern of fusion femoral stem, its by connect conehead, neck, handle body, slide-and-lock groove, fixedly pulp cavity bar, attachment screw, metal reinforcing plates are formed.Said modules, diseases such as by being used in combination, the satisfied outer femur splitting that goes for performing the operation, femur fracture, femur defect.The femur that can connect splitting fast or fracture is farthest saved operating time, makes the patient can better recover the normal motion function of human body, increases the service life of prosthese in human body.
Advantage of the present utility model and benefit:
1, this utility model femur pattern of fusion femoral stem is simple in structure, makes easily.Described femur pattern of fusion femoral stem under the situation of not adding any assembly, can be used as common femoral stem and uses, and also can be used as first hip-joint replacement prosthesis and uses.Operation is simple, and cost is low, and is widely applicable.
2, this utility model femur pattern of fusion femoral stem in first hip replacement surgery, when the femur sclerotin occurring when not good, can install and fix the pulp cavity bar, plays the far-end fixation.Increase being connected between prosthese and the femur, play the effect of better fixed fae body.
3, this utility model femur pattern of fusion femoral stem in first hip replacement surgery, when femur splitting or femur splitting occurring and when damaged, can install fixedly pulp cavity bar and metal reinforcing plates according to circumstances additional or only adorn metal reinforcing plates separately.By selecting for use of combination, not only can take the circumstances into consideration to increase constant intensity according to surgery situation, the problem in the solution operation that also can be quick, economic, it is painful that the patient is exempted once more, early recovery.
Foregoing has illustrated the beneficial effect of this utility model patented technology scheme fully, below in conjunction with the drawings and specific embodiments this utility model is done further narration, so that the public is to having more deep understanding in the utility model, the embodiment of the specific embodiment is best technical scheme, and is not to restriction of the present utility model.

The specific embodiment
As shown in Figure 1 and Figure 2, the utility model discloses a kind of femur pattern of fusion femoral stem.Its by connect conehead 1, neck 2, handle body 4, slide-and-lock groove 3, connecting thread 5, fixedly pulp cavity bar 6, a pair of attachment screw 7 and two metal reinforcing plates 8 are formed.
This utility model femur pattern of fusion femoral stem and assembly can be made with titanium alloy.
According to different instructions for uses, as shown in Figure 2, fixedly pulp cavity bar 6 can screw in femoral stem body 4 afterbodys by connecting thread 5, plays and strengthens fixed effect.Metal reinforcing plates 8 is passed slide-and-lock groove 3 by two attachment screws 7 and is connected, and plays the effect of resected femur near-end.Femoral stem body after the slide-and-lock groove can allow to connect is done to adjust up and down, to adapt to rational fitting depth and stress is installed.
Said modules, by being used in combination, go for the operation diseases such as outer femur splitting, femur fracture, femur defect of likeing, the femur that can connect splitting fast or fracture, farthest save operating time, make the patient can better recover the normal motion function of human body, increase the service life of prosthese in human body.
Claims (3)
1. femur pattern of fusion femoral stem, it by connect conehead (1), neck (2), handle body (4), slide-and-lock groove (3), connecting thread (5), fixedly pulp cavity bar (6), a pair of attachment screw (7) and two metal reinforcing plates (8) are formed.
2. according to claim 1 described a kind of femur pattern of fusion femoral stem, it is characterized in that, femur pattern of fusion femoral stem handle body side surface has slide-and-lock groove (3), and a pair of attachment screw (7) passes slide-and-lock groove connection both sides metal reinforcing plates (8) and clamps the splitting femur, reaches fixation.
3. according to claim 1 described a kind of femur pattern of fusion femoral stem, it is characterized in that femoral stem and assembly thereof are made by titanium alloy.
