AI Technical Summary

Technical Problem

During endoscopic surgery, after the water inlet device is turned off, the residual pressure in the pipes causes water to continue flowing, affecting the precision of the surgical procedure.

Method used

An adjustable water pressure inlet device was designed. By setting a cut-off pipe and auxiliary components in the delivery pipe, the baffle and the rotating shaft are used to push the baffle open by the pump pressure. When the pump stops, the baffle resets and closes, preventing residual water from flowing into the endoscope pipeline.

Benefits of technology

It effectively prevents residual water in the tubing from obstructing the endoscope lens, improves the precision of water flow control, ensures a clear surgical field, and guarantees the normal progress of the surgical procedure.

Abstract

This utility model relates to the field of endoscopic surgical equipment technology, and discloses an adjustable water pressure inlet device for endoscopic surgery. It includes a control box and auxiliary components including a compartment inside a flow-stopping tube. Rotating grooves are provided on the inner walls of both ends of the compartment. A rotating shaft is installed inside the rotating groove, and multiple toothed blocks are provided on the outer wall of the rotating shaft. A baffle is provided at one end of the rotating shaft. A cavity is provided on the inner wall of the rotating groove, and an electromagnet and a spring are installed on the inner wall of the cavity. A slider is installed inside the cavity, with a locking tooth at one end and a magnetic plate at the other end. This utility model achieves water flow interception through the baffle inside the flow-stopping tube at the end of the delivery tube. The pressure of the water delivery pushes the flow-stopping tube open to allow water inlet. The supporting force of the baffle closes the flow-stopping tube when the water flow stops, preventing residual clean water in the delivery tube from continuing to flow into the endoscope pipeline and affecting the image, improving the accuracy of water flow control, and ensuring the normal use of the endoscope.
