AI Technical Summary

Technical Problem

Existing endoscope tip heat dissipation solutions are inefficient in confined spaces, failing to effectively reduce temperature and posing a risk of low-temperature burns. Furthermore, the liquid cooling medium faces high flow resistance in confined spaces, hindering rapid heat dissipation.

Method used

A segmented cold fluid flow channel is set on the endoscope tip, and the cold fluid is divided by multiple channels. Combined with a grid plate and a hydrophilic coating, the contact area and wettability between the liquid and the inner wall of the flow channel are improved. A micro pump and a water tank are used to realize liquid cooling circulation and enhance the heat dissipation effect.

Benefits of technology

It improves the heat dissipation efficiency of the tip, reduces the fluid flow resistance, ensures the safety and service life of the endoscope, and avoids the risk of low-temperature burns.
