Laparoscopic rigid shaft/tube

Material:

• Usually made of high-strength stainless steel (such as 304 or 316L), which is corrosion-resistant and has high mechanical strength.
• Sometimes lightweight titanium alloy or other alloy materials are used to reduce the weight of the equipment.

Function:

• Protect the internal optical lens and fiber optic cable from external damage.

• Deliver the camera, light source, etc. to the surgical site through the mirror tube.

• Provide a channel for surgical instruments (some laparoscopes are designed as multi-functional channels to allow other surgical tools to pass through).

Length and diameter:

• Length: Usually 20cm-30cm, the specific length is adjusted according to the type of surgery and the surgical site.

• Diameter: Common diameters are 5mm, 10mm, 12mm, etc. The smaller the diameter, the smaller the incision to the patient.

High polished 316 stainless steel making points

●    Selects the high quality of the powder, special process properly

●    Develop appropriate binder formula

●    Can develop high hardness of 316 l products, hardness is 200 hv, look at mirror polishing effect.

Key point：

●    Finer powder

●    Optimized binder

●    Sintering atmosphere

●    Impurity control
