Micro air pump is a key component in medical endoscpy devices. How to use the micro air pump in the field of medical endoscopy and minimally invasive?

With the development of electronics and digital video technology, electronic endoscopes are gradually used in medical diagnosis and minimally invasive fields. Endoscope is an integrated monitoring instrument that integrates various technologies such as optics, ergonomics, precision machinery, modern electronics, mathematics, and software. The electronic endoscope enters the human body through the natural orifice of the human body or the percutaneous puncture channel,The lesion can be seen directly at the relevant parts , and make a diagnosis of the lesions under direct vision or take a biopsy of the lesions for pathological diagnosis.

Treatment or implantation of man-made products that have a therapeutic effect. Minimally invasive surgery refers to surgery performed using modern medical instruments such as endoscopes and related equipment. It has the advantages of less trauma, less pain, and faster recovery. It is a revolutionary progress in modern medical surgery.

With the development and popularization of medical speculum and minimally invasive technology, some auxiliary equipment for endoscope and minimally invasive surgery have also appeared on the market, in order for medical workers to conveniently participate in endoscopic diagnosis and minimally invasive surgery of patients’ lesions.

Common applications of micro air pump:

1.Irrigation is to use the micro air pump to generate positive pressure to transmit the liquid medium to pressurize and expand the cavity, which is used to improve the visual space of the speculum, and can clean the blood in the cavity, making the observation and surgical field of vision clearer, suitable for various laparoscopy and surgery.

2.Waste liquid suction, through the micro pump to generate negative pressure on the airtight container, to suck the liquid medium( perfused by the speculum or the medical waste liquid generated by the operation) into the negative pressure container.

3. Suction cutting, through the micro air pump to generate negative pressure on the airtight container, suck human tissue to assist cutting, and attract the cut tissue fragments into the negative pressure container.

For the above-mentioned application cases, such as perfusing liquid with a micro positive pressure pump and negative pressure suction with a micro vacuum pump which can effectively avoid the risk of cross-infection. At the same time, a pressure sensor can be installed to adjust the speed of the micro pump through the closed-loop control of the host computer to indirectly control the liquid flow rate and pressure.
