An auxiliary straight tube with illumination function for use with endoscopes

Abstract

An auxiliary straight tube with illumination function for use with an endoscope includes: an inner tube, which is a non-flexible straight tube; a light strip surrounding the inner tube; an electrical connection sleeve fitted onto one end of the inner tube, the electrical connection sleeve having an electrical connector for connecting to an external power source and other electronic signal sources, the electrical connector being electrically connected to the light strip; and a light-transmitting protective member covering the light strip and integrated with the inner tube, the light-transmitting protective member also being integrated with the electrical connection sleeve and covering at least a portion of the electrical connection sleeve, the light emitted by the light strip being projected outward through the light-transmitting protective member, the light-transmitting protective member protecting the light strip from contact with external objects; wherein, the electrical connection sleeve and the inner tube are spatially connected, allowing an endoscope flexible tube to pass through.

Claims

1. An auxiliary straight tube with illumination function for use in an endoscope, comprising: an inner tube, which is an inflexible straight tube; a light strip surrounding the inner tube, the light strip being energized to emit light; a power connector sleeve fitted over one end of the inner tube and covering a portion of the inner tube externally, the power connector sleeve having a shoulder for the end of the inner tube to abut against, the power connector sleeve having an electrical connector for connecting to an external power source and other electronic signal sources, the electrical connector being electrically connected to the light strip; and a light-transmitting protective member covering the light strip and integrated with the inner tube, the light-transmitting protective member also being integrated with the power connector sleeve and covering at least a portion of the power connector sleeve, the light emitted by the light strip being projected outward through the light-transmitting protective member, the light-transmitting protective member protecting the light strip from contact with external objects; wherein... The electrical connection sleeve is spatially connected to the inner tube, allowing an endoscope hose to pass through.

2. The auxiliary straight tube with illumination function for use with an endoscope as described in claim 1, wherein: The light-transmitting protective component is an inflexible straight tube. The light-transmitting protective component has a notch at one end where the power-connecting sleeve is located. The power connector of the power-connecting sleeve protrudes from the body of the power-connecting sleeve and is located within the notch. The outer end of the power-connecting sleeve is flush with the other end of the light-transmitting protective component, and the power-connecting sleeve is fixed to the light-transmitting protective component by at least one fastener.

3. The auxiliary straight tube with illumination function for use with an endoscope as described in claim 2, wherein: It further includes an end sleeve, which is fitted over the inner tube and the light-transmitting protective element. The end sleeve has a stop surface that stops at one end of the inner tube, and the end sleeve is provided with a spacer located between the inner tube and the light-transmitting protective element, so that a certain distance is maintained between the inner tube and the light-transmitting protective element.

4. The auxiliary straight tube with illumination function for use with an endoscope as described in claim 3, wherein: The spacer is ring-shaped and is secured to the spacer by a plurality of fasteners passing through the end sleeve and the light-transmitting protective element from the outside.

5. The auxiliary straight tube with illumination function for use with an endoscope as described in claim 3, wherein: The stop surface of the end sleeve is located at one end of the light-transmitting protective element.

6. The auxiliary straight tube with illumination function for use with an endoscope as described in claim 3, wherein: The light-transmitting protective component has an opening, a microphone module is disposed outside the inner tube and within the range of the opening, and the opening is located inside the end sleeve. The microphone module is electrically connected to the electrical connector via the lamp.

7. The auxiliary straight tube with illumination function for use with an endoscope as described in claim 3, wherein: The light strip is located between the end sleeve and the power connection sleeve, but not inside the end sleeve.

8. The auxiliary straight tube with illumination function for use with an endoscope as described in claim 1, wherein: The power connection sleeve has a push-pull neck with a gradually decreasing diameter from the outer end to the other end. The smallest diameter of the push-pull neck is smaller than the diameter of the inner tube, and the shoulder is located at the smallest diameter of the push-pull neck.

9. The auxiliary straight tube with illumination function for use with an endoscope as described in claim 1, wherein: The light strip is spirally wound around the inner tube.

10. The auxiliary straight tube with illumination function for use with an endoscope as described in claim 1, wherein: The light-transmitting protective component is selected from transparent resin or optical adhesive, or from transparent soft rubber that has been injection molded.
