Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0043] As shown in the figure, the vertebral body balloon dilation plastic system includes a balloon dilation catheter 1, a pressurized pump 2, a combined probe 3, a guide wire 4, an expansion sleeve 5, a protective sleeve 6, a drill bit 7, and bone cement advancement. device 8. The balloon dilation catheter 1 is composed of a Y-shaped tee pipe 103, a balloon 102, a balloon catheter 101, a balloon guide wire 104, and a marker pin 105. The balloon dilation catheter 1 is provided with a balloon guide wire 104, Keep the balloon catheter 101 upright to act as a stent, and assist the balloon dilation catheter 1 to be inserted into the vertebral body; the rear end of the balloon catheter 101 is connected with a Y-shaped three-way pipe 103, and the Y-shaped three-way pipe 103 has a Y-shaped One is connected with the pressurizing catheter 203, and the other...

Abstract

The invention provides a centrum balloon dialation forming system and belongs to the technical field of medical operation devices. The system comprises a balloon dilating catheter, a pressure pump, a combined probe, a guide wire, a dilation sleeve, a protective sleeve, a drill bit and a bone cement propeller. When the centrum balloon dilation forming system is applied to treatment of vertebral hemangioma, metastatic tumor and osteoporotic fracture, a water soluble contrast medium is injected by virtue of a puncture needle of the pedicle of vertebral arch to carry out intraosseous venography, the situations that the contrast medium seeps out of an end plate and bone cortex or stays in bones can be displayed clearly, and whether the contrast medium is spread to the opposite side when injected from a single side can be displayed; and various balloon shapes, such as flat shape, spherical shape, bullet shape, peanut-liked 8 shape, elliptical shape and the like, are designed on the balloon dilating catheter. Through adoption of the system, different operation centrums and operation methods can be selected, so that complications are reduced; an injector with scales, a handle and a rotary nut are designed to effectively control the pressure when bone cement is injected, so that the exosmosis because the strength cannot be controlled can be solved; and the system has the advantages of convenience in operation and safety and practicality, the operation risk is remarkably reduced and the success rate of operations is high.

Description

technical field [0001] The invention belongs to the technical field of medical surgical instruments, in particular to a vertebral body balloon expansion forming system for treating vertebral hemangiomas, metastatic tumors and osteoporotic fractures. Background technique [0002] At present, conservative treatment methods are usually used for osteoporotic fractures, including long-term bed rest, wearing braces, etc. Elderly patients have many complications caused by long-term bed rest, and left with persistent symptoms of thoracolumbar and back pain, which is more painful; while traditional surgery Internal fixation is risky and costly, and because of osteoporosis, the screw has no grip point, and the failure rate of the operation is high. Vertebral hemangiomas generally have no obvious symptoms. Individual hemangiomas invade the vertebral body severely, leading to microfractures or even collapse of the vertebral body, causing pain or compressing the spinal cord and nerve roo...
