Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0018] A kind of laser perforation method of medical PTCA balloon, such as figure 1 , figure 1 The medical PTCA balloon 1 is referred to as the balloon for short, and the laser perforation method includes the following steps:

[0019] S1. Place the medical PTCA balloon 1 to be punched on the adsorption platform 2 .

[0020] The specific process is as follows: the medical PTCA balloon 1 to be punched is placed on the adsorption platform 2 and the adsorption platform 2 is opened, and the medical PTCA balloon 1 is adsorbed on the adsorption platform 2 . Both ends of the medical PTCA balloon 1 are connected with an air pipeline 3 . The air pipeline 3 is connected to the inflation device, and air can be injected into the medical PTCA balloon 1 through the inflation device and the air pipeline 3 . The inflation device can adopt the inflation and...

Abstract

The invention discloses a laser perforation method and a laser perforation device for a medical PTCA balloon, relates to the technical field of manufacturing of human body drug delivery devices, and solves the problems of high operation difficulty and non-uniform aperture size of laser perforation of an existing medical PTCA balloon. The laser perforation method comprises the following steps: placing a medical PTCA balloon to be perforated on an adsorption platform; inflating the medical PTCA balloon to enable the medical PTCA balloon to bulge, wherein the bulged medical PTCA balloon is adsorbed on the adsorption platform; punching the medical PTCA balloon by adopting ultraviolet laser; and deflating the medical PTCA balloon and the taking down the medical PTCA balloon from the adsorption platform. The laser perforating device comprises a laser perforating unit, an adsorption platform, an inflation unit and a control unit. According to the laser perforation method, hot melting of the balloon is extremely small, tiny holes can be perforated, the perforating size and range can be easily controlled, no special clamp is needed for fixing, the fixing effect is good, no impurity is left inside, cleanliness and safety of a later operation are guaranteed, the perforating difficulty is lowered, and the perforating efficiency is high.

Description

technical field [0001] The invention relates to the technical field of manufacturing a medicine delivery device for a human body, in particular to a laser perforation method and a laser perforation device for a medical PTCA balloon. Background technique [0002] PTCA balloon dilatation catheter balloon coronary intervention will gradually become popular in clinic. By perforating the wall of the balloon, the liquid medicine in the balloon can be accurately directed to the affected part of the blood vessel, which reduces the use of medicines, reduces medical costs, and avoids the need for medicines. Waste; Second, the precise control of the dosage can greatly reduce the side effects of the drug itself. During the treatment process, the drug slowly seeps out from the wall hole of the balloon through a certain pressure. After the treatment is completed, the excess drug in the balloon needs to be pumped out. Or the blood flows back into the balloon through the hole in the wall o...
