Abstract
A memory alloy vertebral body bracket is made of a shape memory alloy material and comprises a front end, a rear end and a main body, wherein the main body is provided with central support sheets which can be combined to form rectangle shape and up and down corresponds, two sides of the central support sheets are provided with arc-shaped side sheets, two ends of the central support sheets and the side sheets are folded and sleeved in a front end found pipe and a rear end round pipe which are respectively provided with an open pore, and the combined cross section of the two central support sheets is approximately rectangular. The memory alloy vertebral body bracket is integrally made of memory alloy planking with temperature memory function, can be expanded to an approximate cuboid cavity in the vertebral body, and has quite small configuration, thereby being convenient for realizing minimally invasive surgery, moreover, the cross section is designed in rectangle shape, thus the resetting stability after the memory alloy vertebral body bracket is implanted can be effectively resolved. When being implanted in a diseased vertebra, the memory alloy vertebral body bracket can produce restoring force with the help of body temperature, lead the collapsing vertebral body to recover to a setting height, and have sufficient supporting force to keep the recovering height of the vertebral body for a long time, thereby achieving the effect of curing vertebral body collapse.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, the Intrapyramidal a kind of memorial alloy vertebral body support of particularly a kind of implantation.
Background technology
Spinal fracture can be caused by multiple factor.It can be divided into physics responsible (violence traumatic fracture), age physiologic factor (osteoporosis), biological factor histological type such as (antibacterial inflammation, abscess) according to the cause of disease.The spinal fracture treatment is divided into expectant treatment and operative treatment, and operative treatment mainly is open internal fixation treatment at present, causes surgical wound big, and convalescent period is long, and the patient stands more misery; The Kyphon balloons technique of Chu Xianing became the perfect Minimally Invasive Surgery method of spinal treatments in recent years, had shortened the operation healing stage greatly, and had effectively reduced operation risk.Employed packing material but another kind of risk also appearred thus,---the risk that bone cement is revealed.The Chinese utility model patent " the expansible orthopedic repositor ZL 20082006206.5 of vertebral body " of using and giving birth to has been eliminated this risk, because limitation of design, instability after its circular cross-section structure causes implanting and strength inequality can not be with better effects of the expansible orthopedic repositor performance of this vertebral body.
The utility model content
This utility model purpose provides and a kind ofly can form approximate cuboid cavity at the vertebral body intramedullary expansion, and profile is small, is convenient to realize Minimally Invasive Surgery, and Cross section Design is rectangle, can effectively solve a kind of memorial alloy vertebral body support of the stability when resetting after the implantation
The purpose of this utility model is achieved through the following technical solutions:
A kind of memorial alloy vertebral body support is made by shape memory alloy material, comprises front end, rear end and main body, and main body is provided with two and combines and be rectangular corresponding center support sheet up and down, and the both sides of center support sheet are provided with arcual lateral plate; The two ends of center support sheet and lateral plate are drawn in and are sleeved in front end pipe and the rear end pipe, are respectively equipped with perforate on front end pipe, the rear end pipe.
The cross section of described two center support sheets combination is approximate rectangular.
The stage casing external diameter of described center support sheet is less than the external diameter of lateral plate.
The length of described front end pipe and rear end pipe is 2mm～3mm, and diameter is 3mm～4mm.
Described lateral plate is 4, and is relative in twos up and down.
This utility model is formed by the memorial alloy sheet material integral production with temperature memory function, can form approximate cuboid cavity at the vertebral body intramedullary expansion, profile is small, is convenient to realize Minimally Invasive Surgery, and Cross section Design is a rectangle, can effectively solve the stability when resetting after the implantation.It is implanted in the trouble vertebra, produce restoring force by body temperature, the vertebral body that will subside returns to the height of setting, and has enough support forces, and long-term the maintenance recovered vertebral height, reaches the effect for the treatment of collapse of vertebra.
Manufactured materials of the present utility model is selected the memory alloy material with excellent biological compatibility for use, as Ti-Ni marmem, and safe in vivo, nontoxic, nothing rejection.

The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail:
A kind of memorial alloy vertebral body support is made by shape memory alloy material, comprises front end 1, rear end 2 and main body 5.It is approximate rectangular that main body 5 has two cross sections of making up into rectangular 3, two center support sheets of corresponding center support sheet up and down 3 that combine.There is arc lateral plate 4 both sides of center support sheet 3, and lateral plate 4 is relative in twos up and down, have 4.The stage casing external diameter of center support sheet 3 is less than the external diameter of lateral plate 4.The two ends of center support sheet 3 and lateral plate 4 are drawn in and are sleeved in front end pipe 1 and the rear end pipe 2, are respectively equipped with perforate 6,7 on front end pipe 1, the rear end pipe 2.The length of front end pipe 1 and rear end pipe 2 is 2mm～3mm, and diameter is 3mm～4mm.Center support sheet 3 and the supported on both sides sheet 4 moulding back approximate diameter of a circles of profile are 3mm～4mm before implanting, and it is parallel with the vertebral body centrage to implant rear center's support chip 3, and support resets.
