ENDOSCOPE · 3 items

Endoscope components

The scope body enters the patient through the insertion tube, instruments pass through the Biopsy Channel, and the articulating section is wrapped by the Viton Bending Rubber — three items, each built to your finished-scope assembly drawing.

Endoscope Insertion Tube

Endoscope Insertion Tube
Endoscope insertion tube close-up — braid pattern and printed scaleDetails →

The part of the scope that enters the body. Built as jacket, braid and liner, with the port flared smooth so head assembly goes easily.

Outer diameter0.8 – 6.8 mm
Inner diameter0.5 – 6.0 mm
JacketTPU · PA12 · PEBAX
ReinforcementStainless steel
LinerPTFE · PA12 · PEBAX · PVDF
GI, bronchial, urological and gynaecological scopes

Biopsy Channel

Biopsy Channel
Biopsy channel — coil-reinforced PTFE tube tipDetails →

The passage forceps, snares and haemostasis tools travel through. A PTFE inner layer keeps friction low; an ePTFE outer layer takes repeated flexing and cleaning.

LayersTwo-layer forceps channel
Inner layerPTFE — low friction
Outer layerePTFE — expanded, porous

Viton Bending Rubber

Viton Bending Rubber
Viton bending rubber — black thin-wall tube cross-sectionDetails →

The serpentine component that wraps an endoscope's bending section. It holds shape through curved paths, reducing twisting and breakage and making articulation stable.

Item by requirement
If passage friction is the problemA PTFE inner layer in the biopsy channel lowers the friction forceps and snares meet.
If there is cold storage or transportViton Bending Rubber stays elastic down to −35 °C.
If you assemble the headInsertion tubes ship with the port flared smooth, so assembly goes faster.
If reprocessing cycles are frequentThe ePTFE outer layer and Viton both take repeated cleaning and flexing.
Send an assembly drawing and quantity and we reply within three business days.

Processes that run alongside

Endoscope components usually arrive bundled with reinforced tubing and secondary processing.

FAQ

FAQ

What diameters does the insertion tube cover?

The published range is OD 0.8 – 6.8 mm and ID 0.5 – 6.0 mm. Anything outside that is agreed from your drawing.

Can we choose the jacket material?

TPU, PA12 and PEBAX are available, and durometer can be stepped along the length so the distal end is softer.

Why is the biopsy channel two layers?

The PTFE inner layer lowers instrument friction and the ePTFE outer layer takes repeated flexing and cleaning. One material rarely does both well.

How thin can the Viton bending rubber go?

Down to a 0.1 mm wall. The serpentine profile holds its shape even that thin.

Does it hold up in the cold?

Viton Bending Rubber stays elastic to −35 °C, so cold storage or air transport is not an issue.

Can we source all three together?

Yes. Send an assembly drawing and we quote insertion tube, biopsy channel and Viton bending rubber as one package.
