Abstract
Disclosed is a composite dynamic lumbar vertebra fixing device. A titanium alloy screw is fixed on each of an upper L-shaped base and a lower L-shaped base, the upper end of an upper flexible plastic sleeve is connected with a sliding piece which is connected with a sliding groove in the bottom of the upper L-shaped base to enable the upper flexible plastic sleeve and the upper L-shaped base to be in sliding connection, the lower end of a lower flexible plastic sleeve is connected with a sliding piece which is connected with a sliding groove in the bottom of the L-shaped base to enable the lower flexible plastic sleeve and the lower L-shaped base to be in sliding connection, and an alloy spring is mounted between the upper flexible plastic sleeve and the lower flexible plastic sleeve. The composite dynamic lumbar vertebra fixing device can change shape along with bending of the lumbar vertebra of a human body to fit the human body, and only part of parts need to be replaced when the fixing device is replaced, so that suffering caused to a patient is reduced, and expense caused by integral replacement is lowered; an adjusting ejector head and an adjusting screw can slightly adjust strength of the alloy spring, so that optimal treatment effect can be brought to the patient.
Description
Technical field
The present invention relates to a kind of armarium, be specifically related to a kind of lumbar vertebra dynamic fixation device.
Background technology
Lumbar degenerative disease is commonly encountered diseases and the frequently-occurring disease of orthopaedics, and clinical at present take operative treatment as main method, but plant bone mass absorbs, fusion device moves after loosening, the problem of fusion device depression because operative treatment exists.Therefore, draw dynamic fixation system in medical science, namely when not bone-graft fusion, change the mode of motion segment bearing load by external fixture, make lumbar vertebra under the protection of dynamical system, obtain self and repair.
Current, the flexible member of lumbar vertebra dynamic fixation device is on the market single, cannot complete posture conversion, and fixture being designed to integral type, needing integral replacement when changing when human body making exercise attitudes.
Summary of the invention
Main purpose of the present invention is to provide a kind of combined type lumbar vertebra dynamic fixation device, and this device can carry out flexural deformation with human action wearing in process, and laminating body shape makes human motion and changes convenient.
A kind of combined type lumbar vertebra dynamic fixation device, comprise Titanium Alloy Screw, upper L-type pedestal, lower L-type pedestal, slide plate and chute, also comprise alloy spring, upper flexible garment bag, lower flexible garment bag, set screw and adjustment top, described upper L-type pedestal, lower L-type pedestal is fixed with Titanium Alloy Screw respectively, described flexible garment bag upper end connects slide plate, slide plate is connected with the chute of upper L-type base bottom, make to be formed between flexible garment bag and upper L-type pedestal to be slidably connected, described lower flexible garment bag lower end connects slide plate, slide plate is connected with the chute of lower L-type base bottom, make to be formed between lower flexible garment bag and lower L-type pedestal to be slidably connected, alloy spring is arranged between flexible garment bag and lower flexible garment bag.
Described lower flexible garment bag inside is provided with set screw, regulates top to be arranged in set screw by screw thread.
Beneficial effect of the present invention is: a kind of combined type lumbar vertebra dynamic fixation device provided, this device is provided with alloy spring, alteration of form can being carried out with the bending of human body lumbar vertebra, with human body of fitting, the human body sense of discomfort that minimizing brings because of fixing device for installing when carrying out every motion can being made.By arranging slide plate and chute, removable parts original paper is only needed when changing fixture, the device being fixed on human body need not be changed, reduce the slight illness brought to patient, the general expenses produced when simultaneously reducing integral replacing, top and set screw is regulated the dynamics of alloy spring to finely tune, for patient brings the therapeutic effect of the best.
Accompanying drawing explanation
Figure 1 shows that the structural representation of combined type lumbar vertebra dynamic fixation device.
Detailed description of the invention
Hereafter will describe the specific embodiment of the invention in detail in conjunction with concrete accompanying drawing.It should be noted that the combination of technical characteristic or the technical characteristic described in following embodiment should not be considered to isolated, they can mutually be combined thus be reached better technique effect.In the accompanying drawing of following embodiment, the identical label that each accompanying drawing occurs represents identical feature or parts, can be applicable in different embodiment.
The structural representation of the combined type lumbar vertebra dynamic fixation device shown in composition graphs 1, can find out, combined type lumbar vertebra dynamic fixation device, comprise Titanium Alloy Screw 101, upper L-type pedestal 105, lower L-type pedestal 106, slide plate 107 and chute 108, also comprise alloy spring 102, upper flexible garment bag 103, lower flexible garment bag 104, set screw 112 and adjustment top 111, described upper L-type pedestal 105, lower L-type pedestal 106 is fixed with Titanium Alloy Screw 101 respectively, described flexible garment bag 103 upper end connects slide plate 107, slide plate 107 is connected with the chute 108 bottom upper L-type pedestal 105, make to be formed between flexible garment bag 103 and upper L-type pedestal 105 to be slidably connected, described lower flexible garment bag 104 lower end connects slide plate 107, slide plate 107 is connected with the chute 108 bottom lower L-type pedestal 106, make to be formed between lower flexible garment bag 104 and lower L-type pedestal 106 to be slidably connected, alloy spring 102 is arranged between flexible garment bag 103 and lower flexible garment bag 104.Upper L-type pedestal 105, chute 108, slide plate 107 and upper flexible garment bag 103 all have screwed hole 109, be fixed together by screw 110, same, lower L-type pedestal 106, chute 108, slide plate 107 and lower flexible garment bag 104 all have screwed hole 109, is fixed together by screw 110.Described lower flexible garment bag 104 inside is provided with set screw 112, regulates top 111 to be arranged in set screw 112 by screw thread.
During use, by the Titanium Alloy Screw 101 be arranged on upper L-type pedestal 105 and lower L-type pedestal 106, fixture is fixed on treatment position, when changing alloy spring 102, open screw 110, upper flexible garment bag 103 and lower garment bag 104 are taken out in direction along chute 108, change alloy spring 102, by regulating the elastic force of top 111 and set screw 112 alloy spring 102 to finely tune, then upper flexible garment bag 103 and lower garment bag 104 are arranged on upper L-type pedestal 105 and lower L-type pedestal 106 by chute 108.
Although give some embodiments of the present invention, it will be understood by those of skill in the art that without departing from the spirit of the invention herein, can change embodiment herein.Above-described embodiment is exemplary, should using embodiment herein as the restriction of interest field of the present invention.
