Medical apparatus

Abstract

The invention provides a medical apparatus capable of isolating, with a simple structure, a fluid succeeding unit connected with the fluids such as air supply and water supply, and a non-fluid succeeding unit connected with the non-fluids such as an optical system, a signal line and a power system, and the medical apparatus also has high reliability of waterproof strategy. The medical apparatus is characterized in that the apparatus includes: an insertion part side body (50) of an endoscopic (21) as a first component; the power unit (50) as a second component, which includes a receiving chamber (71) which is connected with the insertion part side body (50) in a manner of free assembly and disassembly and the outer circumferential part of which is surrounded by walls; the fluid succeeding unit which is located out of the receiving chamber (71) and connected to the insertion part side body (50); and the non-fluid succeeding unit which is located inside of the receiving chamber (71) and connected to the insertion part side body (50).

Description

technical field [0001] The present invention relates to, for example, a medical device including an endoscope main body located at a proximal end of an insertion portion of the endoscope and a power unit connected to the endoscope main body. Background technique [0002] In an endoscope as a medical device, a main body portion is provided at a base end portion of an insertion portion for insertion into a body cavity, and a universal cord connected to a light source device or the like is connected to the main body portion. Built-in items such as signal lines connected to the illumination optical system and the observation optical system, bending operation wires, and air / water supply or suction pipes pass through the insertion portion. Furthermore, the main body is provided with the illumination optical system, signal lines, and connection portions of various pipes, and also provided with a bending operation portion for bending the bending portion, and various operation button...

AI Technical Summary

Problems solved by technology

Therefore, since it is necessary to isolate the illumination optical system and the electrical system from the fluid systems such as air supply / water supply and suction, the structure in the connection part is complicated

[0012] In Patent Document 2, it is configured to connect the electrical system and the fluid system at the same time by connecting the insertion part and the main body part. However, since these connections are made in one connector housing, the structure in the connecting part complex

[0013] In Patent Documents 3 and 4, since the power transmission system from the electric motor constituting the bending drive unit is exposed, waterproof measures during cleaning are required, and the structure is complicated

Furthermore, when the endoscope is in use, a torsional force is applied to the insertion part, and the torsional force of the insertion part is directly applied to the power transmission part, so it is likely to have adverse effects on the power transmission system.
