Title
(EN) SINGLE-USE UTERINE ENDOSCOPE
(FR) ENDOSCOPE UTÉRIN À USAGE UNIQUE
(ZH) 一种一次性子宫内窥镜
Abstract
(EN) A single-use uterine endoscope, relating to the technical field of medical instruments, and comprising a handle mechanism (1) and a cannula mechanism (6). The cannula mechanism (6) comprises a rotating inner tube (61) and a supportive outer tube (62), one end of the rotating inner tube (61) being connected to the handle mechanism (1), and the other end being connected to a camera (64). The supportive outer tube (62) is sleeved on the circumference of the rotating inner tube (61), one end of the supportive outer tube (62) being fixedly connected to the handle mechanism (1), and the other end being provided with a bending segment (621), a continuous bending groove (622) being provided on the bending segment (621), and the continuous bending groove (622) being distributed helically along the circumference of the bending segment (621). The single-use uterine endoscope has the effect of causing any cross section of the bending segment (621) to have two stress points, such that when the bending segment (621) is stressed, the bending segment (21) is supported by the stress points and cannot easily be snapped, thereby helping to reduce the medical risk of the bending segment (621) breaking in the uterus.
(FR) L'invention concerne un endoscope utérin à usage unique, relevant du domaine technique des instruments médicaux, et comprenant un mécanisme de poignée (1) et un mécanisme de canule (6). Le mécanisme de canule (6) comprend un tube interne rotatif (61) et un tube externe de support (62), une extrémité du tube interne rotatif (61) étant reliée au mécanisme de poignée (1), et l'autre extrémité étant reliée à une caméra (64). Le tube externe de support (62) est emmanché sur la circonférence du tube interne rotatif (61), une extrémité du tube externe de support (62) étant relié de manière fixe au mécanisme de poignée (1), et l'autre extrémité étant pourvue d'un segment de courbure (621), une rainure de courbure continue (622) étant formée sur le segment de courbure (621), et la rainure de courbure continue (622) étant répartie en hélice sur la circonférence du segment de courbure (621). L'endoscope utérin à usage unique a pour effet que n'importe quelle section transversale du segment de courbure (621) a deux points de contrainte, de telle sorte que, lorsque le segment de courbure (621) est contraint, le segment de courbure (21) est supporté par les points de contrainte et ne peut pas facilement se casser, ce qui contribue à réduire le risque médical de rupture du segment de courbure (621) dans l'utérus.
(ZH) 一种一次性子宫内窥镜,涉及医疗器械技术领域,包括手柄机构(1)以及插管机构(6),插管机构(6)包括旋转内管(61)和支撑外管(62),旋转内管(61)的一端与手柄机构(1)转动连接,另一端连接有摄像头(64);支撑外管(62)套设于旋转内管(61)周向,支撑外管(62)的一端与手柄机构(1)固定连接,另一端设置有弯折段(621),弯折段(621)上开设有连续的折弯槽(622),折弯槽(622)沿弯折段(621)的周向呈螺旋排布。一次性子宫内窥镜具有使得弯折段(621)的任意一个截面上都有超过两个的受力点,弯折段(621)受力时,在各受力点的支撑下弯折段(621)较难折断,从而便于降低弯折段(621)断裂在子宫内的医疗隐患的效果。
