Description
Technical field
This utility model relates to a kind of device for the treatment of collapse of vertebra and compression fracture, relates in particular to the device of a kind of minimally-invasive treatment collapse of vertebra and compression fracture.
Background technology
Traditional treatment collapse of vertebra and compression fracture are otomy, and this method exists wound greatly and and the shortcomings such as many of issuing licence.Make joint efforts through the various countries scholar, explored a kind of effective and safe new method-Minimally Invasive Surgery.
Said Minimally Invasive Surgery is to open one or several aperture on patient body, and the surgeon is by means of various visual pattern equipment and advanced dexterous operating theater instruments equipment then, operating theater instruments is entered human body through too small otch treat or diagnose.Compare with traditional open operation, micro-wound surgical operation is little to the wound of health tissues, has reduced various operations and issues licence, and has improved in patient's art and postoperative body and mind comfort level, has shortened the post-operative recovery time, is the inexorable trend of surgical operation development.
For adapting to the Minimally Invasive Surgery needs, multiple injectable packing material, be developed as polymethyl methacrylate bone cement (PMMA), calcium phosphate bone cement (CPC), calcium sulfate paste etc., by percutaneous vertebral body Wicresoft injection operation, but carry the paste of in-situ solidifying to the vertebral fracture particularly of the fracturing position that subsides, can obtain significant analgesic effect, the height of compression vertebral body is obviously recovered and correct the kyphosis deformity.This injection minimally-invasive treatment method relates to injectable materials and is the apparatus system of realizing the injectable purpose.Injectable material such as injectable PMMA, CPC etc. are accepted extensively by the clinician.Cause that operation risk etc. all depends on the transmission device system that is adopted to some extent and prevent that the material seepage from going out when the convenience that material is carried, the effect of filling treatment and operation.
The percutaneous Minimally Invasive Surgery is used for the development of collapse of vertebra and compression fracture treatment technology and has experienced two stages: the phase I is exactly percutaneous vertebroplasty (percutaneous vertebroplasty, PVP), promptly under the guiding of X line perspective, puncture needle pedicle or sternocostal joints are penetrated pathological changes vertebral body and compression fracture position, then bone cement or other implant are injected next firm vertebral body in collapse of vertebra position and compression fracture, to strengthen vertebral body and compression fracture hardness, intensity, stable fracture and pain relieving.The defective of this method is that bone cement was in flow regime before solidifying, exist large tracts of land to contact with surrounding tissue, exist implant to flow out into the intravital danger of body from vertebral body intracavity portion, the venous plexus that implant enters into spinal canal, intervertebral foramina or vertebral body can block them or be taken away by blood, thereby causes the possibility of thrombosis or infarction.In order further to improve the effect of Minimally Invasive Surgery, second stage after the improvement is percutaneous kyphoplasty art (percutaneous kyphoplasty, PKP), promptly before bone cement injects, at first implant a balloon-expandable, the cavity that subsides that need is injected bone cement struts the formation cavity through inflation, bone cement is concentrated injected cavity body then, significantly reduced the contact area of various tissues in bone cement and the cavity like this, material also is easy to injection.But the bone cement that is in flow regime before solidifying concentrates the border of injection place still to contact with cavity tissue and body fluid, and the curing of material can be subjected to the influence of body fluid, and still there is the potential danger that leaks into spinal canal, intervertebral foramina in the material that injects.In a word, still there is unsatisfactory part in injectable Wicresoft interventional therapy collapse of vertebra in process of clinical application, how to improve the conveyer device of injection material, and to keep the advantage of Wicresoft's interventional therapy, the deficiency that overcomes existence becomes the key of dealing with problems.So optimize to import the material of apparatus structure of bone filler and function of use the collapse of vertebra disease that better Minimally Invasive Surgery is used for a variety of causes and causes is just seemed extremely important.
In the manufacturing of material conveying device, one of problem is to select for use which kind of suitable material manufacture to go out to meet protruding shaping conveyor behind the vertebral body of clinical requirement.Higher because of the vertebral body internal pressure, so the material that requires to introduce sacculus can bear required high pressure of bearing in the expansion expansion process, and can resist the damage that bony spur may cause sacculus.Problem two for because balloon expandable need be withdrawn from after forming cavity, and current methods is that the bone cement direct injection is filled in the cavity, contact so the bone cement that injects still exists with the border of surrounding tissue, thereby still have the probability of bone cement seepage.
The apparatus of introducing bone cement at present has: Granted publication CN2785549Y patent, a kind of treatment vertebral compression fracture balloon expandable pipe is provided, and the material property of the not mentioned making sacculus of this patent is so can't guarantee the required requirement of bearing pressure of sacculus;
Granted publication CN2487345Y patent; a kind of percutaneous kyphoplasty art device is provided; this patent is punctured by bony spur for avoiding dilating sacculus; add the contraction support that has overlapped a tinsel formation at sacculus; because be the metal coating support, need second operation to take out or the intravital problem of the permanent delay of foreign body so exist.
Summary of the invention
This utility model technical issues that need to address provide the system of a kind of minimally-invasive treatment collapse of vertebra and compression fracture, to overcome the above-mentioned defective that prior art exists, satisfy the needs of clinical treatment.
The system of said minimally-invasive treatment collapse of vertebra and compression fracture comprises Y type injection seat, guide thimble, balloon-expandable, degradable protection air bag, expansion syringe and the conduit with two inlets;
An inlet of one end of said Y type injection seat is connected with the expansion syringe by conduit, the other end of Y type injection seat is connected with an end of guide thimble, degradable protection air bag and balloon-expandable are enclosed within the other end of guide thimble respectively independently, the logical atmosphere of another inlet of Y type injection seat (1) one end also is provided with control valve, and the interpolation metal needle works effects such as supporting guide thimble simultaneously;
