Femtosecond laser micro-nano-processing technology for nozzle machining: no carbonisation, no burrs, no thermal effects

With the continuous development of medical technology, femtosecond laser technology, as a high-precision, heat-affected-free processing method, is widely used in the field of medical device manufacturing. This paper introduces the principles, advantages, and application cases of femtosecond laser perforation equipment in medical nozzle processing, and discusses its potential for improving the quality, performance, and productivity of medical nozzles.

Medical nozzles are one of the common components in medical devices and are used in applications such as drug sprays and inhalation appliances. Traditional machining methods have some limitations in the manufacturing of medical nozzles, such as low machining accuracy and high thermal influence. And the emergence of femtosecond laser technology provides a new way to solve these problems.

Femtosecond laser is a kind of laser with extremely short pulse time, and its pulse time is on the order of femtosecond (10^-15 seconds), so there is almost no thermal influence in the processing. Femtosecond laser perforation equipment makes use of this characteristic to enable high-precision processing of workpieces such as medical nozzles. The principle is to use a laser to generate a plasma on the surface of a substance, and by controlling the laser energy and the position of the focusing point, tiny holes are formed on the surface of the workpiece.

Advantages of femtosecond laser technology in medical nozzle processing:

1、High precision: Femtosecond laser can achieve micron-level processing accuracy, which can meet the strict requirements of medical nozzles on hole diameter and shape.

2, no thermal impact: due to the extremely short pulse time, femtosecond laser processing process almost no thermal impact, can avoid thermal damage and deformation of the material.

3、No residue: Femtosecond laser processing is non-contact, does not produce cutting residue or debris, to ensure the cleanliness of the medical nozzle.

4、Efficient automation: Femtosecond laser processing can achieve a high degree of automation, improving the productivity and stability of medical nozzles.

Application cases:

1, medical nebuliser nozzle: the use of femtosecond laser technology processing of medical nebuliser nozzles, can be achieved by controlling the flow rate and particle size of the drug spray, to improve the therapeutic effect.

2, inhaler nozzle: femtosecond laser perforation equipment can be achieved in the inhaler nozzle tiny holes, improve the inhalation effect, improve patient comfort.

Femtosecond laser technology has shown great potential in medical nozzle processing, and its high precision and no thermal influence have made it an important processing process in the manufacture of medical devices. With the further development of the technology and the promotion of its application, it is believed that femtosecond laser technology will play an even more important role in the field of medical device manufacturing and bring more innovation and progress to the cause of healthcare.
