Embodiment 1

[0095] An endoscope with expandable end includes an insertion part and an endoscope main body, the insertion part includes a casing, a working cavity, a camera and a wire belt; the working cavity, the camera and the wire belt are all located in the casing; one end of the wire belt is connected to The camera is connected, and the other end passes through the casing to connect with the main body of the endoscope. The camera is arranged at the end of the casing; there is a gap at the end of the casing, and the working cavity or the camera can be stretched out or retracted from the gap. When the working cavity or the camera extends When the gap is opened, the working cavity and the camera are in a juxtaposed state. The wire tape is flat, and the wire tape includes wires arranged in parallel and a sheath wrapping all the wires together.

Embodiment 2

[0097] It is basically the same as Embodiment 1, except that the endoscope with an expandable end also includes a wedge-shaped block, one end of which is a plane and the other end is an inclined plane, the plane end of the wedge-shaped block is connected to the camera, and the inclined-plane end of the wedge-shaped block It is connected with the working cavity, which is a pipe independent of the casing, and the notch on the casing is set on one side of the slope of the wedge block (the gap on the casing is opposite to the slope of the wedge block); the slope of the wedge block and the slope of the wedge block The axial angle is 30°. When the executive end of the endoscope reaches into the target position, push the working channel, the working channel slides out along the slope of the wedge block, and protrudes from the gap of the shell, and is in a parallel position with the camera. At this time, the medical The instrument is inserted into the working cavity for various operat...

Embodiment 3

[0099] It is basically the same as Embodiment 2, except that the endoscope with an expandable end also includes an elastic sleeve, which is arranged at the end of the housing where the camera is installed, and wraps the camera and the housing gap. This can further improve the protective effect.

Abstract

The invention discloses an endoscope with an enlargeable tail end. The endoscope comprises an insertion part and an endoscope main body, wherein the insertion party comprises a shell, a working tract, a camera and a wire band; the working tract, the camera and the wire band are located in the shell; one end of the wire band is connected with the camera, and the other end of the wire band is connected with the endoscope main body after penetrating the shell; the camera is arranged at the tail end in the shell; a gap is formed at the tail end of the shell so that the working tract or the camera can extend out or retract from the gap; when the working tract or the camera extends out the gap, the working tract and the camera are in a parallel state. The endoscope with the enlargeable tail end can realize the enlarging and retracting of the tail end of the endoscope; the tail end of the endoscope is enlarged after passing through a narrow human body tract so that the working tract or the camera can extend out; the working tract and the camera are located at the parallel positions, so that the inner diameter of the working tract is obviously increased, the working tract can pass through more instruments to take out larger foreign matters.

Description

technical field [0001] The invention relates to an endoscope with an expandable end, which belongs to the field of medical instruments. Background technique [0002] Endoscope is a common medical device at present. It usually includes an insertion part that goes deep into the body cavity, and an endoscope main body. A camera module for image acquisition is arranged in the insertion part, and the output image signal is transmitted to the endoscope outside the human body. It is processed in the main body and further transmitted to the back-end control and display circuit, which is convenient for doctors to detect and perform related operations. There are many kinds of endoscopes, including thoracoscopes, laparoscopes, hysteroscopes, otoloscopes, and the like. [0003] The common problem of all endoscopes at present is that the inner diameter of the working cavity is small and the scope of application is narrow. This is related to the traditional structure of the endoscope. T...
