As the core component for realizing flexible steering in the cavity, the precision processing of curved part of endoscope is directly related to the accuracy of diagnosis and treatment operation and patient safety. Traditional mechanical processing is prone to cause burrs or dimensional deviation of snake bone joints, while the endoscope bending section laser cutting machine provides a breakthrough solution for curved part manufacturing through non-contact and high-precision characteristics, promoting the upgrading of minimally invasive instruments to a more reliable and refined direction.

 

The bending section of the endoscope needs to achieve multi-directional bending in a tube with a diameter of less than 5mm, and the joint cutting accuracy directly affects the flexibility and durability of movement. Laser cutting uses ultra-fast pulse technology to achieve 0.02mm-level slits on nickel-titanium alloy or stainless steel pipes, and the uniformity of joint gap is improved by more than 90%, avoiding the risk of motion jamming or metal fatigue fracture caused by traditional processing. For example, an international brand uses fiber laser technology to control the tolerance of joint components to ±1μm, significantly improving the passability of colonoscopes in complex intestinal environments.

 

The endoscope bending section needs to be densely grooved to reduce weight and enhance flexibility. The laser cutting machine uses three-dimensional path programming to simultaneously complete the processing of hundreds of special-shaped slots on the tube wall without secondary assembly, and the processing efficiency is 4 times higher than that of electrochemical etching. At the same time, the characteristics of no chemical residue meet the medical-grade cleanliness standards and ensure the biosafety of the device.

 

Medical-grade titanium alloys or polymer coating materials are sensitive to heat, and traditional processes are prone to oxidation or coating peeling. The extremely short pulse (10^-15 seconds) of the femtosecond laser hardly produces a heat-affected zone, ensuring the smoothness of the cutting surface and the mechanical properties of the material, and extending the service life of the device.

 

In response to the ultra-fine diameter requirements of neuroendoscopy, pediatric endoscopes, etc., the laser cutting machine completes micron-level structure processing on a 0.1mm thick tube wall, and integrates a guidewire channel or biopsy hole position to achieve "one tube with multiple functions" and help carry out complex procedures.
