Application of laser welding machine in medical industry

As a precision machining tool, laser has unique application prospects in the field of medical equipment.

The main application fields of medical device products are: gastroenterology, minimally invasive medicine, orthopedics, cardiovascular and cerebrovascular and various surgical instruments.

The main products of medical auxiliary materials are: various types of applicators, colloids, disposable medical equipment, medical reagent bottles, test boxes, etc.

Laser technology is used in the medical industry, and it is currently mainly concentrated in welding, cutting, marking and other fields;

1. Gastroenterology:

Disposable biopsy forceps

a. The welding of the pliers sleeve and the spring tube, the one-ring sealing welding technology was used in the early days, and now the 6-point symmetrical welding is used. b. Welding of hinge connection points and anti-dropping requirements. c. Welding of probes with needles.

Disposable digestive tract hemostatic clip

The appearance is the same as the biopsy forceps, the forceps head is designed in the form of a collet, the collet seat sleeve and the spring tube of the welding point are welded, and the 6-point symmetrical welding.

2. Minimally invasive surgical instruments:

Various minimally invasive surgical endoscopes, laparoscopes, otolaryngoscopes, arthroscopes, brain mirrors, etc. The main welding is: mirror base + sleeve welding, light guide + light guide base welding, lens + inner and outer sleeve welding, window sealing welding, etc. There are many technical difficulties, high process requirements, and fine materials.

3. Surgical suture instruments:

stapler

Precision welding of stapler stapling head housing.

4. Welding of cardiovascular and cerebrovascular instruments:

Cardiovascular and cerebrovascular device products are mostly small and precise products with high added value and high technical requirements, with strong material specificity, small welding parts, and high requirements.

5. Orthopedic equipment welding:

Orthopedic joint implants have a large number of artificial hinges, pins, and components; these types of products are directly implanted into the human body for a long time, and require extremely high structural stability. All link points need to be cured by laser spot welding to prevent them from falling off.

6. Conduit welding:
