Description

Novel vertebral body forming bilateral high-viscosity bone cement injection three-way pipeline

Technical Field

The utility model belongs to the technical field of medical equipment, concretely relates to novel centrum shaping both sides high viscosity bone cement injection tee bend pipeline.

Background

Osteoporotic vertebral fracture is a common fracture type of old people, is the preferred treatment method at present, is percutaneous vertebroplasty and percutaneous kyphoplasty, and has the advantages of small wound, quick pain relieving, capability of getting out of bed at early stage, and the like. The traditional vertebroplasty adopts low-viscosity bone cement, and is characterized by small molecular weight, long liquid state retention time, short dough period, large pressure in the injection process, wide dispersion range, easy leakage and the like. With the technical development of material engineering, the high-viscosity bone cement is gradually applied to vertebral body forming operation, shortens the liquid phase of the low-viscosity bone cement mixing process, has the characteristics of instantaneous high viscosity, long injectable time, good initial mechanical support effect, low polymerization temperature, uniform bone cement dispersion distribution and the like, and has definite clinical curative effect, safety and effectiveness. The traditional low viscosity bone cement vertebroplasty adopts a common injection system, and consists of a puncture needle, an expansion sleeve, a working sleeve, an injector and the like. With the appearance of high-viscosity bone cement, the traditional injection system cannot be competent for the injection task of novel bone cement materials, and the high-viscosity bone cement needs to be injected by adopting a combined hydraulic injection system. At present, products of Kyphon company, A-Spine company, Qiangsheng company, Disc-O-Tech and other companies exist internationally, but the cost is relatively high, and a corresponding bone cement injection system, namely the Mairelix system, is invented by Zhongshan medical hall company in 2008 at home. The system consists of an injector and a 3.0 puncture working sleeve, and the step of inserting an expansion sleeve in the traditional operation is omitted after puncture positioning, so that the operation time is further shortened, the operation steps are simplified, and the curative effect is exact in the unilateral vertebroplasty process. However, due to the properties of bone cement, this system has certain limitations in bilateral vertebroplasty procedures. If one side is injected first and then the other side is injected, the properties of the bone cement are different when the two sides are injected, which may cause the bone cement to be deviated from a solidification state when the other side is injected, resulting in uneven dispersion on the two sides. Furthermore, due to the long time interval, the bone cement has solidified in the injection system after the initial injection, blocking the tubing, resulting in injection failure. If two-side operations are to be performed simultaneously, two sets of bone cement injection systems are required, which greatly increases the operation cost of patients.

In order to simultaneously inject bilateral bone cement by utilizing one set of system in one operation, the applicant invents a novel vertebral body forming bilateral high-viscosity bone cement injection three-way pipeline, thereby meeting the operation requirement of simultaneously injecting bilateral bone cement.
