Endoscopy parts|Components and functions of flexible endoscopes

1. Components of flexible endoscopes

The components of the flexible endoscope are the operating part, the insertion part (insertion tube part, bending part, tip part), the light guide bending section part and the light guide head part.

2. Eyepiece

The flexible endoscope does not have an eyepiece. Instead, it is equipped with 1-4 switch buttons. Each switch can arbitrarily set up some panel functions of the processing center through the keyboard, such as fixing, metering, contour enhancement, AGC, enlargement, printing, etc.

3. Flexible endoscope Operation parts

The flexible endoscope operation unit includes a air/water button, an attraction button, a large and small knob, an S cover, an operation handle, a biopsy channel opening valve, a biopsy channel interface, a air/water tube interface, an angle adjustment device, and a traction wire.

4. Tip of flexible endoscope

The insertion site is the insertion tube part, the binding part, and the Tip part

5. Light guide bending part

The light guide bending part contains CCD, beam, water tube,air tube, suction tube, ground wire,button control line.

6.Light guide head part

It includes a light guide plug rod, an air plug rod, a horizontal interface, a ground wire interface, and a suction port. the guide head needs to have electrical contacts and needs to be waterproof. therefore, when soaking the side leakage, you need to bring a waterproof cover, and the side leakage head must also be on the waterproof cover.

Pentax light guide head includes a light guide plug rod, a water bottle interface, a ground wire interface, an suction port, and a leak detector. compared with olympus, the pentax guide head has a relatively large appearance structure because there is a drive board inside, and olympus’s drive board is in the host.

Fujinon light guide head includes a light guide plug rod, an air plug rod, a water bottle interface, a ground wire interface, an suction port, and a leak detection head. compared with olympus and pentax, fujinon’s guide head and ccd connection seat are separated, so it is more inconvenient to operate.
