Cold light source in a ring and is arranged at the front end of contiguous block, and described temperature sensor is arranged on the periphery of contiguous block.
It is using the advantage of above-mentioned technical proposal：The external diameter of contiguous block is identical with the external diameter of extension tube so that extension tube and company
The stitching portion for connecing the outer circumference surface of block is more smooth, it is not easy to damage is caused to human viscera organ, and causes laparoscope
Integraty is stronger, more attractive in appearance；Cold light source is using annular and is arranged at the front end of contiguous block, shooting that can be with extension tube front end
Head keeps identical direction, reaches more preferable lighting effect.
As further improvement of the utility model, provided with anti-between the rear end of the contiguous block and the step surface of extension tube
The sealing ring that only liquid enters.
It is using the advantage of above-mentioned technical proposal：Because electrode slice is such as between the rear end of contiguous block and the step surface of extension tube
Fruit, which touches liquid, may occur the hidden danger such as short circuit, set sealing ring to prevent liquid entry into electrode slice here,
Improve the safety and stability of equipment.
As further improvement of the utility model, it is evenly equipped with the outer circumference surface of the contiguous block axially extending anti-skidding
Convex tendon.
