Thermoplastic forming mold of implantable flexible magnetic control bladder pump

Abstract

The invention relates to a thermoplastic forming mold of an implantable flexible magnetic control bladder pump. The bladder pump comprises a mold core, a front mold box, a rear mold box, a front mold box insertion block group and a rear mold box insertion block, wherein the mold core is composed of a mold core main body and a mold core handle; the shape of the mold core main body is matched with the shape of a filled bladder; the shape of the mold core handle is matched with the shape of a urethra connected with the bladder; the top of the front mold box is provided with a plurality of insertion grooves matched with the front mold box insertion block group; a front mold containing cavity is formed in the front mold box; an insertion hole matched with the rear mold box insertion block is formed in the top of the rear mold box; a rear mold containing cavity is formed in the rear mold box; and the mold core handle is arranged in the rear mold containing cavity. The implantable flexible magnetic control bladder pump prepared by the thermoplastic forming mold can effectively and permanently solve dysuria diseases such as nerve type bladder dysfunction; 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 force applied by an external magnetic field under the condition that no additional pipeline is connected.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a thermoplastic molding mold for 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 U...

Problems solved by technology

[0007] This application provides a thermoplastic molding mold 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 mold is provided, so that the implantable flexible magnetically controlled bladder pump prepared by it can effectively and permanently solve the urination such as neurological 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
