Embodiment Construction

[0012] A method for manufacturing a novel anti-displacement water-conducting silicone tube placed in the brain, the manufacturing method is as follows:

[0013] (1) Design and manufacture molds according to drawings;

[0014] (2) Liquid silicone injection molding;

[0015] (3) Divide the thermosetting liquid silicone rubber (LSR) into two components, A and B, separate the crosslinking agent (hydrogen-containing silicone oil) and the catalyst (platinum), and put them into the two components respectively. Mix A and B components;

[0016] (4) Before each injection molding, put the two components of A and B on the rubber mixer to mix evenly, and then put it into the injection mold cavity immediately. Under the pressure of the press, the rubber will flow into the six holes through the runner. In the mold, and then heated and pressurized vulcanization, made of silicone rubber thin-walled micro-hose;

[0017] (5) remove the edge and trim the formed support;

[0018] (6) Use a las...

Abstract

The invention discloses a manufacturing method of a novel displacement-preventing water guide silicone tube placed in the brain. The manufacturing method of the novel displacement-preventing water guide silicone tube placed in the brain includes the following steps that firstly, a die is manufactured according to the drawing design; secondly, liquid silicone injection forming is conducted; thirdly, thermoset liquid silicone rubber (LSR) is divided into an A component and a B component, a cross-linking agent (containing hydrogen silicon oil) and a catalyst (containing platinum) are separated and are put into the two components correspondingly, and the A component and the B component are then mixed during use; fourthly, before each time of injection molding, rubber materials of the A component and the B component are put on a rubber mixing machine to be evenly mixed and then are put into an injection molding cavity immediately, under the pressure effect of a press machine, the rubber materials pass through a runner and flow into a six-hole die, then heating and pressurizing vulcanization is conducted, and the silicone rubber thin-wall micro rubber tube is manufactured; fifthly, a formed support is subjected to edge demounting and trimming; and sixthly, a laser punching machine is used for punching the formed support. The manufacturing method of the novel displacement-preventing water guide silicone tube placed in the brain is simple in technology and low in cost, and the manufactured silicone rubber tube is proper in hardness and not likely to be aged and can be applied to the field of hydrocephaly drainage surgeries at a large scale.

Description

technical field [0001] The invention relates to the technical field of hydrocephalus treatment, in particular to a manufacturing method of a novel anti-displacement water-conducting silicone tube placed in the brain with low manufacturing cost, suitable hardness and softness, and which is not easy to age. Background technique [0002] Endoscopic midbrain water-conducting silicone tube molding is an important means of treating hydrocephalus. The existing water-conducting silicone tubes are too expensive to manufacture and are prone to aging, resulting in insufficient toughness. Long-term use needs to be replaced regularly. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a method for manufacturing a novel anti-displacement water-conducting silicone tube placed in the brain with low manufacturing cost, suitable hardness and softness, and not easy to age. [0004] A method for manufacturi...
