Thermoplastic molding method of implantable flexible magnetically controlled bladder pump

Abstract

The invention relates to a thermoplastic molding method of an implantable flexible magnetically controlled bladder pump, comprising the following steps: preparing a ferromagnetic composite through organic silica gel, polydimethylsiloxane resin and magnetic particles; The hot-melt flexible non-magnetic matrix is ​​prepared by using base siloxane resin and brightener; the hot-melt flexible non-magnetic matrix and the ferromagnetic composite are injected and solidified to obtain an implantable flexible magnetically controlled bladder pump. The implantable flexible magnetically controlled bladder pump prepared by the thermoplastic molding method can effectively and permanently solve neuropathic bladder dysfunction and other dysuria diseases. After the flexible magnetically controlled bladder pump is implanted through surgery, it can Under this condition, the function of normal urination is realized through the large torque of the magnetic field force exerted by the external magnetic field.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a thermoplastic molding method of an implantable flexible magnetically controlled bladder pump. Background technique [0002] The rapid development of soft robots applied in the biomedical field aims 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 reconstructing organs. Efforts have been made to use soft-bodied robots 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 due to weak muscle contraction, leading to serious complications and even death. Affected by age, neurological diseases, trauma and diabetes, the incidence of ...

AI Technical Summary

Problems solved by technology

[0007] This application provides a thermoplastic molding method for an implantable flexible magnetically controlled bladder pump, which solves or partially solves the problem of the limited hydraulic pressure provided by the artificial detrusor muscle in the prior art, which is far from the human muscle level and lacks realistic medical design. And the optimization of biological safety, the technical problem that reliable long-term function cannot be realized; a thermoplastic molding method is provided, so that the implantable flexible magnetically controlled bladder pump prepared by it can effectively and permanently solve the urination such as neuropathic bladder dysfunction Difficult diseases, after the flexible magnetic control bladder pump is surgically implanted, the function of normal urination can be realized through the large torque of the magnetic force applied by the external magnetic field without any additional pipelines
