Abstract
The utility model relates to a novel interspinal grafting bone fusion device. The inner wall of the annular base (1) of the novel interspinal grafting bone fusion device is connected with a reinforcing rib plate (2) and provided with an annular recess (3). Self-tapping hollow screw threads (4) are attached to the reinforcing rib plate (2) to form a plurality of hole sites (5) between the reinforcing rib plate (2) and the hollow screw threads (4), and a press cap (6) is positioned in the annular recess (3). The novel interspinal grafting bone fusion device has the design of hollow screw thread self-tapping screwed multiple hole sites and large capacity, and self-tapping screw thread slots are engaged with upper and lower spinal bodies. Fixed strength is increased, more bone contact surfaces are provided, and bone fusion is promoted. The novel interspinal grafting bone fusion device is suitable for Chinese human bodies' physiological characteristics, has the advantages of simple and easy use, low cost and convenient operative procedure, and is entirely made from and processed by titanium alloy according with G B / T 13810-1997.
Description
Technical field
This utility model relates to a kind of novel intervertebral bone-graft fusion device, belongs to manufacture technology field of medical appliance.
Background technology
Lumbar vertebra, cervical vertebra fixing operation are through years development, technology reaches its maturity, the apparatus that is used for internal fixation is also more, though its short term efficacy is good, but in the long-term Clinical Follow-up, internal fixation device often owing to lack axial load support between reliable and stable vertebral body, causes the internal fixation device fatigue fracture easily, need operation once more, so the bone fusion is only permanent.And the application of interbody bone-grafting interfusion device, postoperative can improve the symptom and interpyramidal the stablizing of patient's pain immediately, improves bone and merges probability, reduces complication and the ratio of performing the operation once more.At present, domesticly be used for clinical fusion device, great majority are based on import, and Design and Machining in use not too is fit to Chinese based on American-European human body, and the design bulky complex of while related equipment is operated loaded down with trivial details.
Summary of the invention
The technical problem that this utility model solves: designing a kind of novel intervertebral bone-graft fusion device, is that basic engineering forms with the Chinese visible human, is fit to the Chinese visible human physiological characteristics, be simple and easy to use, cheap, operation technique is convenient, and all adopts the titanium alloy that meets GB/T13810-1997 to be processed into.
Technical solution of the present utility model:
A kind of novel intervertebral bone-graft fusion device, be connected with on its ring-shaped base (1) inwall and strengthen gusset (2), be shaped on annular recess (3), self-taped type hollow out screw thread (4) is attached to strengthening on the gusset (2), make and strengthen forming position, a plurality of hole (5) between gusset (2) and the hollow out screw thread (4), gland (6) is arranged in annular recess (3).
Vertically be connected with the bow load closed reinforcement gusset of homogenize (2) in six on ring-shaped base (1) inwall.Self-taped type hollow out screw thread (4) is a cylindrical thread.Or self-taped type hollow out screw thread (4) is tapered thread, and the end of strengthening gusset (2) is fixed with propeller type termination (7).
Advantage that this utility model compared with prior art has and effect:
1, hollow out screw thread self-taped type screw-in design, hypocentrum on the tapping screw thread groove tight engagement increases constant intensity;
2, top and bottom multi-hole position and high capacity design provides more bone contact surface, position, hole nearly 70%, and the gland made from ultra high molecular polyethylene behind the filling bone piece embeds the annular recess of fusion device rear end, prevents from that the bone piece from coming off to promote the bone fusion;
3, the closed reinforcement gusset of bow load homogenize in six is the bearing type structure, and more stable support is provided, and can impel the bone contact closely and increase structural strength simultaneously again;
4, except using fusion device, need not to add any fixture in the art, and after the product surface anodization, have the better image compatibility, corrosion resistance and abrasiveness and biocompatibility, and have enough intensity and hardness.

The specific embodiment
1,2,5,6 first kind of embodiment of the present utility model described in conjunction with the accompanying drawings.
A kind of novel intervertebral bone-graft fusion device, vertically be connected with the bow load closed reinforcement gusset of homogenize (2) in six on its ring-shaped base (1) inwall, be shaped on annular recess (3), self-taped type cylindricality hollow out screw thread (4) is attached to strengthening on the gusset (2), make and strengthen forming position, a plurality of hole (5) between gusset (2) and the hollow out screw thread (4), gland (6) is arranged in annular recess (3).
After can implanting fusion device according to the needs of patient vertebral body in the operation, be obtained from the body bone graft by correct operating procedure, bone graft is carefully embedded Gongli in the wall that fills up fusion device, do not stay any space, the gland of polythene material being made with instrument is over against the fusion device rear end then, the gland edge " " embed in the annular recess on the ring-shaped base inwall, make gland sealing fusion device.
3,4,5,6 second kind of embodiment of the present utility model described in conjunction with the accompanying drawings.
A kind of novel intervertebral bone-graft fusion device, vertically be connected with the bow load closed reinforcement gusset of homogenize (2) in six on its ring-shaped base (1) inwall, be shaped on annular recess (3), self-taped type taper hollow out screw thread (4) is attached to strengthening on the gusset (2), and the end of strengthening gusset (2) is fixed with propeller type termination (7), and making formation position, a plurality of hole (5) between reinforcement gusset (2) and the hollow out screw thread (4), gland (6) is arranged in groove (3).The method of manipulating is identical with first kind of embodiment.
