Minimal invasive centrum elastic capsule

Abstract

The invention relates to a minimal invasive centrum elastic capsule. The invention aims at the shortcoming that doctor needs to regulate the angle of a puncture needle for many times during the puncturing process when the current centrum expanding saccule conduit device is used and provides the minimal invasive centrum elastic capsule which can be punctured once in order to build a working channel during the puncturing process for curing osteoporosis spinal column compression fracture. The capsule of the invention comprises an elastic capsule, an inner conduit, an outer conduit, a conduit, a Y-joint, a port and a guide rod, wherein the front end of the elastic capsule is fixed with the front end of the inner conduit; the back end of the elastic capsule is clamped between the outer conduit and the conduit; the conduit is connected with a front connector of the Y-joint; a back connector of the Y-joint is connected with the port; a closed channel is formed by connecting the inner cavity of the elastic capsule with the outer conduit and the Y-joint; the guide rod is inserted in the inner conduit; the back end of the guide rod is provided with a handle; the handle is threaded to the port; and a developing ring is arranged on the inner conduit in the cavity of the elastic capsule.

Description

Technical field [0001] The invention belongs to the category of medical devices, and specifically is a minimally invasive vertebral body elastic capsule. Background technique [0002] In elderly patients with osteoporosis, compression fractures of the spine may occur under the action of slight external force. With the aging of society, the incidence of osteoporotic vertebral compression fractures is increasing year by year. The patient suffers from pain, is bedridden for a long time, and the quality of life is significantly reduced. Elderly osteoporotic spinal compression fractures can cause kyphosis, causing pain and loss of limb function. Due to the compression of the vertebral body, kyphosis occurs in the spine, and certain organs in the thoracic and abdominal cavity are compressed, which restricts normal physiological activities. The patient's breathing, heart, and digestive system functions are impaired. The cervical spine, hips, and knees are damaged by protruding or flex...

Problems solved by technology

[0005] The object of the present invention is to provide a method for the treatment of osteoporosis in view of the above-mentioned deficiencies that doctors often have to adjust the angle of the puncture needle several times during the puncture process in the existing vertebral body expansion balloon catheter device in use. A minimally invasive vertebral body elastic capsule that can establish a working channel with only one-time puncture in the puncture process of spinal compression fractures
