Double-balloon dilator for bone surgery

Abstract

The invention discloses a double-balloon dilator for a bone surgery, which belongs to the technical field of medical apparatuses. The double-balloon dilator for the bone surgery is mainly characterized by comprising a pressurizing injection device, a developer syringe and a dilating balloon, wherein the pressurizing injection device is communicated with an inner cavity of the dilating balloon by a conduit; the developer syringe is arranged on the conduit between the pressurizing injection device and the dilating balloon; the dilating balloon comprises a main balloon and an auxiliary balloon; the auxiliary balloon is arranged at the side of the main balloon; the conduit comprises a main conduit and an auxiliary conduit; one ends of the main conduit and the auxiliary conduit are respectively communicated with the main balloon and the auxiliary balloon, and the other ends of the main conduit and the auxiliary conduit are respectively connected with the pressurizing injection device; a hydraulic flow dividing valve is connected to a pipeline among the main conduit, the auxiliary conduit and the pressurizing injection device; and the developer syringe is respectively communicated with the main conduit and the auxiliary conduit by the flow dividing valve. The invention aims to provide the double-balloon dilator for the bone surgery, which can be used for single-side vertebral pedicle puncture so as to achieve the bone cement filling effect with same double-side puncture and is used for treating osteoporotic vertebral compression fracture.

Description

technical field [0001] The invention relates to a medical device, more specifically, to a double-type balloon dilator for orthopedic surgery used for treating pain caused by osteoporotic vertebral body compression fractures. Background technique [0002] In recent years, with the rapid development of various radiographic technologies, optical fiber technology, microendoscopic technology, digital imaging and computer navigation technology, spinal surgery has achieved rapid development. Minimally invasive spinal surgery has also become an important direction in the development of spinal surgery. As an emerging field, minimally invasive spinal surgery has been widely contacted by people. Among the many new techniques of minimally invasive spinal surgery, the technique of percutaneous intravertebral injection of bone cement is mostly used in the treatment of osteoporotic compression fractures of the thoracolumbar column or vertebral body metastases, mainly including percutaneou...

AI Technical Summary

Problems solved by technology

Due to the limited volume of the single balloon of the traditional dilator, it cannot effectively stretch the compressed part of the vertebral body. With the existing technology, the single-balloon dilation of unilateral pedicle puncture cannot achieve the expected effect.
