Abstract
The invention discloses a spine fixing system, which comprises fixing plates, regulating rings, screws and connecting shafts, wherein a plurality of fixing plates are arranged, and are connected with one another through the connecting shafts arranged on the end parts of the fixing plates, mounting holes which can be matched with the screws are formed in two sides of the fixing plates, the regulating rings are arranged in the mounting holes, and the screws are assembled with the mounting holes in a matched manner. According to the spine fixing system, the screws are arranged on the fixing plates, and the angles of the screws can be regulated, so that firm bone anchor connection can be realized, the stability of the whole spine can be ensured, and foreign body sensation of patients can be reduced through regulating the mounting angles of the screws by the regulating rings.
Description
Technical field
The invention belongs to medical instruments field, relate in particular to a kind of spinal fixation system.
Background technology
The history of the existing last 100 years of application of internal fixation of spine art, internal fixation is mainly the thing operations that directly face is connected and fixed knochenbruch in or beyond knochenbruch such as applied metal screw, steel plate, intramedullary needle, steel wire or hone lamella, be used for open reduction of fracture and osteotomy, to keep the reset of folding end.
In existing internal fixation, the screw of implanting conventionally can obtain firm bone and be anchored, yet in the situation that some are special, the position for example bad at bone density, sclerotin is more loose, its hold is less, the screw ratio of implanting is easier to become flexible, cannot realize firm bone and be anchored, will jeopardize the stability of whole interior fixed structure, so that the final therapeutic effect of impact.
Summary of the invention
The object of the present invention is to provide a kind of spinal fixation system, be intended to solve in existing spined internal fixation, the screw of implantation is easy loosening problem under special circumstances.
The present invention is achieved in that a kind of spinal fixation system comprises fixing head, adjustable ring, screw, connecting axle; Described fixing head is some, between fixing head, by being arranged on the connecting axle of self end, connect, described fixing head both sides have can with the installing hole of described screw fit, in described installing hole, adjustable ring is installed, described screw coordinates installation with installing hole.
Further, described fixing head is the shape of rectangle dual-side indent, edge rounding, and upper surface or the lower surface of two fixing heads that are connected are arbitrarily not parallel.
Further, be arranged on the axis antarafacial of the screw of fixing head the same side, be arranged on axes intersect or the antarafacial of the screw of fixing head both sides.
Further, described screw is hollow screw, has external screw thread, and adjustable ring has the female thread coordinating with screw external screw thread.
Further, described adjustable ring is arranged in installing hole, in order to the setting angle of adjustment screw.
Further, the adjustable-angle between the axis of described adjustable ring and the axis of installing hole is 20 °-30 °.
effect gathers
Spinal fixation system of the present invention, screw angle scalable is arranged on fixing head, can realize firm bone anchor chain and connect, and can guarantee the steadiness of whole spinal column, by the setting angle of adjustable ring adjustment screw, has reduced patient's foreign body sensation.

Fig. 1 shows the structure of spinal fixation system of the present invention, and as shown in the figure, the present invention is achieved in that a kind of spinal fixation system comprises fixing head 1, adjustable ring 2, screw 3, connecting axle 4; Described fixing head 1 is some, between fixing head 1, by being arranged on the connecting axle 4 of self end, connect, described fixing head 1 both sides have the installing hole that can coordinate with described screw 3, and adjustable ring 2 is installed in described installing hole, and described screw 3 coordinates installation with installing hole.
Further, described fixing head 1 is the shape of rectangle dual-side indent, edge rounding, and upper surface or the lower surface of two fixing heads 1 that are connected are arbitrarily not parallel.
Further, be arranged on the axis antarafacial of the screw 3 of fixing head 1 the same side, be arranged on axes intersect or the antarafacial of the screw 3 of fixing head 1 both sides.
Further, described screw 3 is hollow screw, has external screw thread, and adjustable ring 2 has the female thread coordinating with screw external screw thread.
Further, described adjustable ring 2 is arranged in installing hole, in order to the setting angle of adjustment screw 3.
Further, the described axis of adjustable ring 2 and the adjustable-angle between the axis of installing hole are 20 °-30 °.
Spinal fixation system of the present invention, screw 3 angle scalable are arranged on fixing head, can realize firm bone anchor chain and connect, and can guarantee the steadiness of whole spinal column, by the setting angle of adjustable ring 2 adjustment screw 3, have reduced patient's foreign body sensation.
Although above-mentioned, by reference to the accompanying drawings the specific embodiment of the present invention is described; but be not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various modifications that performing creative labour can make or distortion still within protection scope of the present invention.
