Abstract
The invention provides an adjustable self-stabilizing type artificial sacrum prosthesis which is arranged between lumbar vertebra and left and right ilia to replace physiological sacrum. The adjustable self-stabilizing type artificial sacrum prosthesis comprises a prosthesis body, and left and right ear shaped joint fusion surfaces which are respectively arranged at two sides of the prosthesis body to be respectively clung to the ear-shaped surfaces of the left and right ilia; a main body nut is used for adjusting the length of the sacrum prosthesis. The adjustable self-stabilizing type artificial sacrum prosthesis has the main advantages that the joint fusion surface are arranged at two sides of the artificial sacrum prosthesis body and are respectively connected and fused with physiological sacrum, and therefore, the osteocyte is promoted to develop quickly, the sacralization is accelerated, the functions of sacrum are covered, and as a result, the purpose of stably reconstructing lumbosacral sacroiliac joints can be achieved.
Description
Technical field
The present invention relates to bone surgery implant, particularly a kind of adjustable self-stabilising artificial crystalline lens of alternative nature rumpbone.
Background technology
Rumpbone is the important step of spinal column to pelvis transition, has extremely important effect to support spinal column, maintenance pelvic stabilization, transmission upper body part physiological loads and external heavy burden etc.Sacral Tumors occupies certain proportion in tumor of spine case, and excision is the Main Means of Current therapeutic Sacral Tumors.It is larger that conventional sacral prosthesis designs, and operation wound is larger, and also very difficult during implantation, postoperative infection probability is larger.But due to the particularity of rumpbone present position, operating difficulty is comparatively large, and usually partly destroys waist sacrum, sacroiliac joint even fully owing to performing the operation, the stable lumbosacral joint of postoperative how restoration and reconstruction is the difficult problem that medical circle is shown great attention to always.The method that under the spinal column that current routine adopts, waist section is rebuild, all there is certain limitation and deficiency in the bone grafting Reconstruction etc. such as following closely excellent Reconstruction, autologous bone or allograph bone, postoperative to loosen, fracture, rejection and fusion are bad etc. happens occasionally, and, bilateral ilium is attached with a large amount of muscle and ligament, after taking out rumpbone, be difficult to bilateral ilium to support to anatomical position originally when conventional sacral prosthesis is implanted, be difficult to the lower waist section functional rehabilitation realizing later stage patient.
Summary of the invention
The invention provides a kind of scalable self-stabilising artificial crystalline lens, with solve the excellent Reconstruction of existing nail or bone grafting Reconstruction postoperatively to loosen, fracture, rejection and fusion are bad etc., and therapeutic effect is not good, and operation wound is larger during conventional sacral prosthesis implantation, implant also very difficult, ilium resets difficult, the problem that postoperative infection probability is larger.
The present invention is achieved through the following technical solutions: a kind of scalable self-stabilising artificial crystalline lens, be arranged between lumbar vertebra and left and right ilium with alternative physiology rumpbone, comprise: prosthetic main, left and right ear articular prosthesis, be separately positioned on the both sides of prosthetic main, for fitting with the auricular surface of left and right ilium respectively.
The surface in left and right ear joint fusion face has microcellular structure further.
Both sides, left and right ear joint are provided with screw hole further.
Both sides, left and right ear joint are provided with the nail be connected with nail-stick system further.
Microcellular structure is the multidirectional micro hole structure be interconnected further, and pore diameter is 800 μm.
Prosthetic main adopts scalable adjustment structure further, supports left and right ilium.
The length scope that prosthetic main regulates further is 30-55mm.
Prosthetic main is made up of medical metal further.
The inside of prosthetic main is provided with bone grafting hole further.
Scalable self-stabilising artificial crystalline lens is to left and right extending until left and right ilium further.
By technique scheme, major advantage of the present invention is: the both sides of scalable self-stabilising artificial crystalline lens have the articular surface merged with both sides ilium, can osteocyte be facilitated very soon to generate, and promotes that bone merges; The physiology that length adjustable is conducive to left and right sides ilium resets, and promotes that lower limb function recovers.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
The structural scheme of mechanism of scalable self-stabilising artificial crystalline lens of the present invention has been shown in Fig. 1.This scalable self-stabilising artificial crystalline lens is made up of three parts, left ear articular prosthesis (1), auris dextra cylindrarthrosis prosthese (2), and prosthetic main (3) three parts form; And prosthetic main (3) carries out length adjustment by adjusting nut (4), to adapt to different anatomic physiological data, and realize the Using prosthesis of little wound and minimal incision *, screw hole (5) is for fixing scalable self-stabilising artificial crystalline lens in double-deck ilium, and the fixing nail (6) of nail rod is for being connected with reconstruction nail-stick system.
Fig. 2 shows the schematic diagram of the artificial rumpbone vacation of scalable self-stabilising and Peripheral Bone respective outer side edges.In this embodiment, scalable self-stabilising artificial crystalline lens instead of physiology rumpbone, in figure when patient's rumpbone because of focus involve cause sacral lack and need to be substituted by prosthese time, the artificial rumpbone vacation of scalable self-stabilising can extend lengthening to the left and right to support left and right ilium (7), it is made to be reset to dissect physiology position, and due to the extruding of bilateral ilium (7), make scalable self-stabilising artificial crystalline lens obtain good primary stability; Now will to adopt screw (8) to carry out reinforcement fixing for the left ear articular prosthesis (1) of described scalable self-stabilising artificial crystalline lens and auris dextra cylindrarthrosis prosthese.
Fig. 3 shows scalable self-stabilising artificial crystalline lens and coordinates schematic diagram with nail-stick system.In this embodiment, scalable self-stabilising artificial crystalline lens is connected by nail (6) with nail-stick system (9), complete the fusion of lumbosacral joint, carry out corresponding bone filling in bone grafting hole (10) inside of scalable self-stabilising artificial crystalline lens, the initial stage of completing stablizes the recovery with function.
Fig. 4 shows the microcellular structure schematic diagram of scalable self-stabilising artificial crystalline lens of the present invention, the left ear articular prosthesis (1) of scalable self-stabilising artificial crystalline lens and surface, auris dextra cylindrarthrosis prosthese (2) fusion face are provided with the microcellular structure (11) be convenient to osteocyte and grown into, this microcellular structure (11) is a kind of multidirectional micro hole structure be interconnected, pore diameter is 800 μm, this hole is conducive to osteocyte and creeps and grow into, and postoperative scalable self-stabilising artificial crystalline lens faying face will merge to reach steady in a long-term with physiological bone structure generation bone.Bone grafting hole (10) can be provided with to hold autologous or allograph bone block and osseous granules in scalable self-stabilising artificial crystalline lens, be implanted into autologous or allograph bone block and osseous granules in preoperative or art can play induction osteocyte to creep the effect of growing into and promoting that bone merges in this bone grafting hole 70, aperture, bone grafting hole 70 is 20mm.
