Abstract

The invention discloses an implantable flexible magnetic control bladder extrusion device, which comprises a flexible magnetic control wrapping body used for wrapping a bladder, the flexible magnetic control wrapping body comprises a flexible non-magnetic base body and a ferromagnetic composite body, and the ferromagnetic composite body is arranged on the outer surface of the flexible non-magnetic base body; the flexible non-magnetic substrate is prepared from organic silica gel, polydimethylsiloxane resin and a brightener through thermoplastic curing; the ferromagnetic complex is prepared from organic silica gel, polydimethylsiloxane resin and magnetic particles through thermoplastic curing. The implantable flexible magnetic control bladder extrusion device can solve urination difficulty caused by low bladder activity/detrusor muscle contraction weakness and the like. After the extrusion device is implanted in an operation, the function of normal urination can be achieved through high torque of magnetic force applied by an external magnetic field without no extra pipeline.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an implantable flexible magnetically controlled bladder extrusion device. Background technique [0002] Soft robotics for biomedical applications are rapidly developing to improve medical conditions and provide novel therapeutic tools, such as surgical instruments, human simulation, and drug delivery. As a class of highly compliant and biocompatible active systems, soft robots hold great promise in assisting organ movement and even organ reconstruction. Efforts have been made to use soft robotics in prosthetic assistive devices for various diseased muscles, such as cardiac muscle, hand muscles, and sphincters. [0003] Underactive bladder (UAB) is characterized by prolonged urination and dysuria due to muscle weakness (DU), leading to serious complications and even death. Affected by aging, neurological diseases, trauma or diabetes, etc., the incidence of UAB is high, a...
