Description
Technical field
This utility model relates to a kind of device for the treatment of compression fracture of vertabral body, is specifically related to a kind of inflatable device for the treatment of compression fracture of vertabral body.
Background technology
Compression fracture of vertabral body (" VCF ") is a kind of common spinal injury and can causes long term disability, and in general, VCF relates to subsiding of one or more vertebral bodys in the spinal column.VCF is unobstructed to occur in the bottom vertebral body of thoracic vertebra or the top vertebral body of lumbar vertebra.VCF is usually directed to the fracture of the front part generation of influenced vertebral body.VCF can cause normal sequence and the curvature of the vertebral body in the involved area of spinal column, and for example lordosis produces distortion.VCF with or relevant deformity of spine for example be since the metastatic disease of spinal column, wound etc. cause or relevant with osteoporosis.Up at present, the doctor still is subject to many limitations aspect lopsided with relevant taking which kind of mode to treat VCF.
The treatment compression fracture of vertabral body generally adopts two kinds of technology, and a kind of is vertebroplasty (PVP), is about to flowable reinforcing material, and normally polymethyl methacrylate (PMMA-often is called bone cement) injects damaged vertebral body by puncture needle.Soon, liquid filling material polymerization and hardness increased, and support vertebral body internally after cement injected, and alleviating pain also prevents from further subsiding through vertebral body.The phenomenon of bone cement seepage appears in this operation easily, and the operation chance of success is low, and is dangerous big.
Another kind of technology is kyphoplasty art (PKP), distensible device is inserted in the damaged vertebral body, then expansion.Take out distensible device, this operation namely forms a cavity in bone, can fill bone cement or other loading material in cavity, makes the bone of fracture can load-bearing.Thereby the reinforcement damaged vertebral body protects it to avoid further subsiding.This modus operandi has solved the situation of bone cement seepage, but operating procedure is numerous and diverse, for the requirement height of operative doctor.
Summary of the invention
For solving the problem that prior art exists, this utility model provides a kind of inflatable device for the treatment of compression fracture of vertabral body, has effectively simplified operating procedure.
This utility model is achieved through the following technical solutions: this utility model comprises body, fixed handle, moving handle, expandable capsule bag, sealing-plug and bone cement inlet; Described body is divided into outer tube and interior pipe, and described interior pipe is positioned at outer tube inside and is longer than outer tube, leaves the space that can hold the capsule bag between described interior pipe and the outer tube; Described capsule bag is arranged in the space of body dispensing end, and interior Guan Yiduan is connected with capsule bag inlet seal, described capsule bag outfan by line to sew up sealing; Manage the other end in described and be provided with sealing-plug, in pipe fixedly connected near the appear on the stage small-bore section of scalariform through hole of the part of sealing-plug and described fixed handle, described fixed handle large aperture section is provided with the axial kidney slot with respect to the axial line symmetry, moving handle one end stretches into fixed handle through hole inside from described kidney slot, and fixedlys connected with the outer tube wall that stretches into fixed handle large aperture section; Pipe also is provided with the bone cement interface near the part of sealing-plug in described.
Further, described inflatable sac bag material is soft macromolecular material.
The beneficial effects of the utility model are: the bone cement of the high pressure that injects when using this utility model to undergo surgery is that the tunica bag is wrapped in, and finishes after vertebral body resets, and the capsule bag is withdrawn from, and has effectively prevented the seepage occurrence probability of bone cement; This utility model is compared with traditional kyphoplasty art, and vertebral body resets and one step of bone cement injection finishes, and has effectively simplified operating procedure, significantly reduces the radiation that doctor and patient are subjected in operation.
Description of drawings
Fig. 1 is user mode sketch map of the present utility model.
Fig. 2 is the unused state sketch map of capsule bag.
Fig. 3 is the user mode sketch map of capsule bag.
In the drawings: the 11-outer tube; Pipe in the 12-; The 2-fixed handle; The step-like through hole of 21-; The 22-kidney slot; The 3-moving handle; 4-capsule bag; The 5-sealing-plug; 6-bone cement inlet.
The specific embodiment
Shown in Fig. 1 ~ 3, this utility model comprises body, also comprises fixed handle 2, moving handle 3, expandable capsule bag 4, sealing-plug 5 and bone cement inlet 6; Described body is divided into outer tube 11 and interior pipe 12, and described interior pipe 12 is positioned at outer tube 11 inside and is longer than outer tube 11, between described interior pipe 12 and the outer tube 11, leaves the space that can hold capsule bag 4; Described capsule bag 4 is arranged in the space of body dispensing end, and interior pipe 12 1 ends are connected with capsule bag 4 inlet seals, described capsule bag 4 outfans by line to sew up sealing; Manage 12 other ends in described and be provided with sealing-plug 5, in pipe 12 fixedly connected near the appear on the stage small-bore section of scalariform through hole 21 of the part of sealing-plugs 5 and described fixed handle 2, described fixed handle 2 large aperture sections are provided with the axial kidney slot 22 with respect to the axial line symmetry, moving handle 3 one ends stretch into fixed handle 2 through hole inside from described kidney slot 22, and fixedly connected with outer tube 11 sidewalls that stretch into fixed handle 2 large aperture sections; Pipe 12 also is provided with bone cement inlet 6 near the part of sealing-plug 5 in described.
Further, described inflatable sac bag 4 materials are macromolecular material.
Further, described interior pipe 12 can be that metal tube also can be non-metallic pipe.
Further, the line of described sealed pouch 4 can be medical cotton thread.
Using method of the present utility model is, body portion is inserted in the spinal column, promote moving handle 3, moving handle 3 drives outer tube and slides backward, and the inflatable sac bag that inserts like this in the spinal column exposes out, injects bone cement from bone cement inlet 6, bone cement enters capsule bag 4 by interior pipe 12, capsule bag 4 expands under the pressure of bone cement, struts epispinal vertebral body, and anterior vertebral is resetted; The line of the outfan of capsule bag 4 ruptures under certain fixation pressure then, capsule bag 4 openings, and bone cement enters in the vertebral body.Withdraw from capsule bag 4 afterwards, bone cement is stayed and is strengthened vertebral body in the vertebral body.
