End head assembly for endoscope

Abstract

Provided is an end head assembly for an endoscope. The end head assembly has a proximal end for connection to other portions of the endoscope and a distal end positioned opposite the proximal end, thedistal end for forming the distal end of the endoscope. The end head assembly comprises: a working channel extending in a longitudinal direction extending from the proximal end of the end head assembly towards the distal end, and a camera assembly including a flexible printed circuit and a camera module, the camera module including an image sensor and a lens group and extending in a longitudinaldirection, the camera module including a proximal connection surface, where the camera module is positioned above the working channel in an up-down direction such that a lateral direction extends transverse to both the camera module and the working channel, wherein the flexible printed circuit extends from a connection with a connection surface of the camera module in a lateral direction beyond the connection surface, forming a first bent portion of the flexible printed circuit toward a proximal end of the end head assembly, and wherein the first bent portion of the flexible printed circuit isarranged proximal to the connection surface of the camera module.

Description

technical field [0001] The present disclosure relates to endoscopes, and more particularly, to a tip assembly for an endoscope. Background technique [0002] Endoscopes are well known for visual inspection of hard-to-reach locations such as body cavities of the human body. Typically, an endoscope includes an elongated insertion tube with a handle at its proximal end (from the operator's point of view) and a device such as a built-in camera at its distal end. Visually inspect the device. The definitions of the terms "distal" and "proximal" as used herein for endoscopes in general are adhered to in this specification, ie proximal is the end closest to the operator and distal is the end farthest from the operator. [0003] As the name suggests, endoscopes are used to look inside the body, such as a patient's lungs or other body cavities. Therefore, modern endoscopes are usually equipped with a light source and visual receptors, including visual sensors such as cameras or ima...

AI Technical Summary

Problems solved by technology

Providing a small tip assembly can be especially challenging where the endoscope includes both a camera and a working channel extending through the tip assembly because the camera and working channel are positioned one above the other within the tip assembly, This takes up space in the radial direction of the tip assembly
