Abstract
The utility model relates to a device for percutaneous vertebral body rear convex plastic operation comprising a percutaneous puncture needle, a catheter and a saccule which are fitting to the percutaneous puncture needle. The percutaneous puncture needle comprises a needle point and a set of ectasia sleeve which are sleeve jointed one by one, the saccule wraps the catheter, a constrictive supporting which is made of tinsel is sleeved around the saccule. The utility model is characterized in that: the front port of the constriction-ectasia sleeve of the ectasia sleeve which is sleeve jointed one by one is made into a zigzag, and the zigzag points incline to the same direction. The utility model can avoid the saccule to be punctured by sclerotin and prevent the saccule from extending into the non-arming area; the fit-to-shape supporting can satisfactorily diaplasis the compressed vertebral body; the supporting recovering memory force and the saccule ectasia force form the resultant force which is easy to spread the compressed vertebral body; the supporting intensity is increased by the integration of the metal supporting and the bone cement.
Description
(1) technical field
This utility model belongs to medical apparatus and instruments.Be mainly used in the operation device that intervene operations such as " percutaneous kyphoplasty arts " is used.
(2) background technology
The percutaneous vertebroplasty is a kind of intervene operation that just grows up at late nineteen eighties, method is under the guiding of videos such as X line, approach by percutaneous puncture injects the pathological changes vertebral body with bone cement, to stop vertebral body to be subsided, remove or ease the pain because of compressed by factors such as tumor destruction or osteoporosis.Causing post kyphosis deformity person for vertebral body compressed subsiding, then is after puncturing successfully, earlier struts the vertebral body of subsiding correcting the post kyphosis deformity with balloon expandable, and then injects bone cement and fixed.Percutaneous kyphoplasty art that Here it is.
But there is weak point in existing operation device, the structure of percutaneous needle comprise needle point and one group step by step the expanded casing of fit constitute room for improvement also arranged.Conduit that and for example enters from sleeve pipe and sacculus also have the deficiency in the use: the balloon expandable in the bone space may run into two troubles: the one, and coarse bone structure may puncture sacculus; The 2nd, sacculus may escape into the hollow area that we do not wish that it enters voluntarily.The weak point of operation device all might influence the success of operation.
(3) summary of the invention
Solution of the present utility model is: percutaneous kyphoplasty art device, comprise that percutaneous needle and the conduit that cooperates with it and sacculus constitute, percutaneous needle comprises needle point and the one group expanded casing of fit step by step, sacculus is wrapped on the conduit, it is characterized in that adding the contraction support that tinsel of cover constitutes at sacculus.Metal rack can discharge, and this support can be made various suitable shape supports with memory alloy material, is narrowed to suitable shape by guide bushings on low temperature.Elder generation's percutaneous puncture and expand the passage of setting up a target approach vertebral body by special expanded casing step by step during operation, then sacculus, support, conduit are imported the target area, to the sacculus pressurization (inflation) of heating, make sacculus and support coextend shaping, strut the vertebral body of subsiding.Discharge support again, withdraw from foley's tube, inject water skiing mud at last and fill up space in the support.
Utilization the utility model has the advantages that: 1, can avoid sacculus to be punctured by sclerotin; 2, prevent that sacculus from escaping into the nontarget area; 3, suitable shape support can reset satisfactorily and compress vertebral body; 4, the strength of the strength of support refresh memory and balloon expandable forms and makes a concerted effort the easier vertebral body that struts compression; 5, metal rack and bone cement combine has increased support strength.
In addition, for the ease of importing the sacculus support, must set up one have enough bores via the passage of skin to targeted vertebral body, and this passage also must be by one section bone space.So, with the port design toothing of expanded casing, and the same direction of crown inclination sensing, as shown in the figure.Like this, when expanded casing enters soft tissue,, just can successfully push soft tissue open, when entering bone sex organization,, just can sever bone sex organization and make smooth advances and put in place as long as along crown direction rotation propelling as long as the rotation of contrary crown direction advances.

Fig. 1 is this utility model structural representation, and is at support and balloon expandable releasing structure sketch map
Fig. 2 is the structural representation of this utility model sclerotin puncture needle
Fig. 3 is this utility model sclerotin puncture needle expanded casing structural representation,
The structural representation that Fig. 4 does not discharge for this utility model
The structural representation of saccule support system among the figure, wherein 1 is conduit, 2 contraction supports for the stainless steel metal wire formation, 3 is sacculus.The structure that Fig. 4 does not discharge when implanting for saccule support system, the expression support has discharged shaping among Fig. 1, and foley's tube has restored to be prepared to withdraw from.The sclerotin puncture needle comprise sclerotin puncture needle 6 among the figure and one group step by step the expanded casing 5 of fit form, 4 is the puncture needle handle.
(5) specific embodiment
Percutaneous kyphoplasty art device, comprise that percutaneous needle and the conduit 1 that cooperates with it and sacculus 3 constitute, percutaneous needle comprises needle point and the one group expanded casing 5 of fit step by step, sacculus is wrapped on the conduit, sacculus generally is made of macromolecule material film, pore is arranged on the conduit, after sacculus puts in place, by conduit to inflated.Sacculus adds the contraction support 2 that tinsel of cover constitutes.Support can be made of the Ultimum Ti silk and reticulate or other various suitable shape shell-like supports, is narrowed to suitable shape by guide bushings on low temperature, is easy to again be strutted by sacculus.Metal rack can discharge, elder generation's percutaneous puncture and expand the passage of setting up a target approach vertebral body step by step by special expanded casing during this operation imports the target area with sacculus, support, conduit then, to the sacculus pressurization of heating, make sacculus and support coextend shaping, strut the vertebral body of subsiding.Discharge support again, withdraw from foley's tube, inject water skiing mud at last and fill up space in the support.The structure of sclerotin puncture needle expanded casing is a joint cover one joint, and the back telescopic caliber of level is bigger, and the anterior port of expanded casing is made zigzag 6, and crown tilts to point to same direction, as shown in the figure, can conveniently enter bone sex organization and soft tissue.When crown tilt to point to other direction also can, when cutting off bone sex organization, carry out with opposite direction.
Claims (3)
1, percutaneous kyphoplasty art device, comprise that percutaneous needle and the conduit that cooperates with it and sacculus constitute, percutaneous needle comprises needle point and the one group expanded casing of fit step by step, and sacculus is wrapped on the conduit, it is characterized in that adding the contraction support that tinsel of cover constitutes at sacculus.
2,, it is characterized in that the network that contraction support that tinsel constitutes is made for the Ultimum Ti silk by the described percutaneous kyphoplasty of claim 1 art device.
3, by the described percutaneous kyphoplasty of claim 1 art device, the expanded casing reducing and expansion that it is characterized in that described fit are step by step opened telescopic anterior port and are made zigzag, and crown tilts to point to same direction.
