Embodiment Construction

[0030] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0031] Aiming at the problem that the existing duodenoscope has a small space and it is inconvenient to realize the function of multi-field of view, this example presents a multi-lens structure scheme, which optimizes the structures of multiple lenses, lighting systems and water and air spray devices. Arrangement and integration make it compact in structure and occupy a small space, so as to realize the multi-field requirements of the duodenoscope.

[0032] The duodenoscope provided in this example includes a lens device, an illumination system, a water and air spray device, an operating mechanism and a control device. The operating mechanism here is a duodenoscope forceps lifting device, a lifting seat, and auxiliary structures such as forceps ...

Abstract

The duodenoscope comprises a lens device, a lighting system, a water and gas spraying device, an operating mechanism and a control device, the lens device comprises a first lens and a second lens, and the first lens and the second lens are arranged at the top end and the first side face of the duodenoscope end respectively. The lighting system, the water and gas spraying device and the lens device are correspondingly arranged in a matched mode and integrated into an integral structure, and the integral structure and the operating mechanism are arranged on the second side face and the third side face of the duodenoscope end respectively and wrapped by a shell with a lateral opening. The control mechanism is in control connection with the lens device, the lighting system, the water and gas spraying device and the operation mechanism. According to the scheme, the forward lens is additionally arranged on the basis of the lateral lens of an existing duodenoscope, the core difficulty of realizing a multi-view-field endoscope structure is solved through optimized arrangement and integration of the structure, and the working performance of the duodenoscope is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of endoscopes, in particular to a duodenoscope with multi-field functions. Background technique [0002] Duodenoscope is mainly used to observe and diagnose the duodenal papilla, facilitate the intubation of the bile duct and pancreatic duct, and diagnose and treat diseases of the biliary and pancreatic system. [0003] Traditional duodenoscopes have only one side-facing lens, with a single and limited field of view. Due to the narrow and tortuous cavity through which the duodenum passes, the forward and backward movement of the lens is a frequent action. For complex working conditions such as lens entry, the traditional duodenoscope with only a single lens sideways has obvious shortcomings. This requires the duodenoscope to have a multi-field function, especially the forward field of view, in order to have more perception of surrounding information.
