Thermoplastic forming method of implantable flexible magnetic control bladder pump

Abstract

The invention relates to a thermoplastic forming method of an implantable flexible magnetic control bladder pump. The thermoplastic forming method comprises the following steps of preparing a ferromagnetic complex from organic silica gel, polydimethylsiloxane resin and magnetic particles; preparing a hot-melt-state flexible non-magnetic substrate from organic silica gel, polydimethylsiloxane resin and a brightener; and carrying out injection molding, curing and forming on the hot-melt-state flexible non-magnetic matrix and the ferromagnetic complex, so that the implantable flexible magnetic control bladder pump is manufactured. The implantable flexible magnetic control bladder pump prepared through the thermoplastic forming method can effectively and permanently solve dysuria diseases such as nerve type bladder dysfunction and the like, and after the flexible magnetic control bladder pump is implanted through an operation, the normal urination function can be realized through high torque of magnetic field force applied by an external magnetic field under the condition of not connecting any additional pipeline.

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
