No-Scalpel Vasectomy (NSV) Set

Quick Answer: The no-scalpel vasectomy set, or NSV set, contains the specialised instruments for the no-scalpel technique of male sterilisation: a ring-tipped fixation clamp and a curved, sharp-tipped dissecting forceps. It is used in family planning training for doctors.

The Two Instruments of the NSV Technique

No-scalpel vasectomy was developed in China by Dr Li Shunqiang in the 1970s and is now widely taught in family planning programmes, including in India. Instead of cutting the skin with a scalpel, the operator fixes the vas deferens under the skin and makes a tiny puncture, which is associated with less bleeding and fewer complications than a conventional incision.

Two instruments make this possible. The ring-tipped vas fixation clamp has a small ring at the end of each jaw; it encircles and holds the vas through the skin without penetrating it. The NSV dissecting forceps have curved, sharply pointed tips; one tip punctures the skin and the closed tips spread the tissue to expose the vas, which is then lifted out. The listing does not state whether other instruments are included, so confirm the contents with the order.

In training, the instruments are first handled on scrotal models so trainees can practise the three-finger technique of isolating the vas and applying the ring clamp.

Specifications

Care & Handling

• Protect the sharp tips of the dissecting forceps with a tip guard during cleaning and storage.
• Clean both instruments with the jaws open, then sterilise and dry.
• Check that the ring clamp’s rings close evenly; misaligned rings will not hold the vas securely.

Applications

• Family planning training for doctors in the no-scalpel technique
• Practising vas isolation and ring-clamp application on scrotal models
• Instrument identification in surgery and urology teaching
• Setting up procedure trays in training centres

Why Choose LabEquip

NSV sets are ordered by medical colleges and family planning training centres that run no-scalpel technique courses. LabEquip lists the set for teaching use in its Biology Lab Products range; the IUCD set in the same range serves the other side of family planning training. Order through the contact page.

Frequently Asked Questions

What instruments are in an NSV set?

The core instruments are a ring-tipped vas fixation clamp and a curved, sharp-tipped NSV dissecting forceps. Some sets add other items, so check the contents list.

How is no-scalpel vasectomy different from conventional vasectomy?

The vas is fixed under the skin with a ring clamp and reached through a small puncture made with the dissecting forceps, rather than through a scalpel incision. It generally causes less bleeding.

What does the ring-tipped clamp do?

Its ring-shaped jaw tips encircle the vas through the skin and hold it firmly without piercing the skin.

Who developed the no-scalpel technique?

Dr Li Shunqiang in China in the 1970s. It has since been adopted in family planning programmes in many countries.

Can the instruments be used on training models?

Yes. Scrotal models let trainees practise vas isolation, ring-clamp application and use of the dissecting forceps before supervised clinical work.

How should the NSV instruments be stored?

Clean, sterilise and dry them, then store with the sharp forceps tips protected, since damaged tips make the puncture step harder.
