Abstract
The utility model discloses a combined type femoral stem prosthesis, which consists of two parts including a neck part and a stem part, wherein the neck part is in taper fit with the stem part, and the taper proportion is 1 to 10, so that the fit is firmer. The combined type femoral stem prosthesis disclosed by the utility model has the advantages that a front rake angle and a back rake angle of the combined type femoral stem prosthesis can be regulated and the combined type femoral stem prosthesis can be turned inwards or outwards according to the difference of neck parts; the original structure of human body bones is conformed to the maximum extent, and the combined type femoral stem prosthesis can be regulated at four angles according to the difference of bones of different patients, so the patients can better recover normal motor functions of human bodies and the service life of the prosthesis in the human bodies is prolonged; the different leg lengths of the patients can be regulated according to the length of the neck part, so the flexibility and the rapidity of an operation are greatly improved, the operation time is shortened, the pain of the patients is lightened and the service life of the prosthesis is prolonged.
Description
Technical field
This utility model relates to a kind of combined type femoral bone end prosthesis, a kind of specifically safe and reliable, optimize range of activity, realize the combined type femoral bone end prosthesis that Minimally Invasive Surgery is implanted.
Background technology
Combined type femoral bone end prosthesis is the artificial prosthesis that is used for hip replacement surgery, the active level that can reach when safety in human body of the installation effect of prosthese and postoperative prosthese in the rationalization degree direct influence art of its design, degree of stability and human motion.Designing a optimization range of activity, realize the prosthese that Minimally Invasive Surgery is implanted, is the target that a lot of artificial prosthetic designs persons pursue.
Replace downright bad expendable artificial hip joint to become more common operation at present for present useful artificial hip joint, but existing hip prosthesis, the ubiquity operation technique is complicated, and otch is bigger, the deficiency that the type femoral bone end prosthesis range of activity is little.For this kind defective of prior art, improvement project is a lot, but all can not get a desired effect.
In sum, for safe and reliable, simple in structure at present, optimize range of activity, realize that still there is the very big market demand in the combined type femoral bone end prosthesis that Minimally Invasive Surgery is implanted.
The utility model content
The purpose of this utility model be to provide a kind of safe and reliable, simple in structure, optimize range of activity, realize the combined type femoral bone end prosthesis that Minimally Invasive Surgery is implanted.
In order to realize the purpose of this utility model, this utility model adopts following technical scheme:
This utility model discloses a kind of combined type femoral bone end prosthesis, and it is made up of cervical region and handle body two parts; Said cervical region and handle body are through taper fit, and the tapering ratio is 1: 10, thereby makes cooperation more fastening.The combined type femoral bone end prosthesis of this utility model is according to different cervical regions, can use handle body and different cervical regions to cooperate, and both assemble easily, and a handle body can cooperate 15 kinds of cervical regions, scalable top rake, back rake angle, in turn over and turn up; Meet skeleton structure originally to greatest extent, can be different according to different patient's skeletons, carry out multiextent adjusting, make the patient can better recover the normal motion function of human body, increase the service life of prosthese in human body.The lower limb length that the patient is different can be regulated according to the length of cervical region, has improved the motility of operation greatly, and convenience has reduced operative incision, has shortened operating time, realizes the Minimally Invasive Surgery implantation, has alleviated less patient suffering, has prolonged the service life of prosthese.
The utility model has the advantages that:
1, the combined type femoral bone end prosthesis of this utility model, simple in structure, assembling easily, can realize Minimally Invasive Surgery.
2, the combined type femoral bone end prosthesis of this utility model can carry out the adjusting of different angle according to the difference of skeleton.
Foregoing has proved absolutely the technical scheme and the beneficial effect of this utility model; Below in conjunction with the accompanying drawing and the specific embodiment 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 the restriction to this utility model.
Description of drawings
Fig. 1 is this utility model perspective view
Fig. 2 is this utility model user mode sketch map
Parts label declaration in the sketch map:
1, cervical region 2, handle body
The specific embodiment
Referring to shown in Figure 1, the combined femoral stem of this utility model comprises cervical region 1, handle body 2; Cervical region 1 adopts taper fit with handle body 2, and the tapering ratio is 1: 10; Like this can simplified structure, reduce doctor's operating time, realize Minimally Invasive Surgery, can be in art flexible center and optimize the hip joint motion.
Referring to shown in Figure 2, the mated condition when cervical region 1 uses with handle body 2.
Be simplified structure, make things convenient for the doctor to operate, said cervical region 1 passes through taper fit with handle body 2, and the tapering ratio is 1: 10, thereby makes cooperation more fastening.The combined type femoral bone end prosthesis of this utility model is according to different cervical regions, can use handle body and different cervical regions to cooperate, and both assemble easily, and a handle body can cooperate 15 kinds of cervical regions, can regulate top rake, back rake angle, in turn over and turn up; Meet skeleton structure originally to greatest extent, can be different according to different patient's skeletons, carry out multiextent adjusting, make the patient can better recover the normal motion function of human body, increase the service life of prosthese in human body.The lower limb length that the patient is different can be regulated according to the length of cervical region, has improved the motility of operation greatly, and convenience has reduced operative incision, has shortened operating time, has alleviated less patient suffering, has prolonged the service life of prosthese.
