SURGEOGUIDE II

SURGEOGUIDE II

Gamma probe system: SURGEOGUIDE II model

A gamma probe is a handheld device used for intraoperative use following interstitial injection of a radionuclide, to locate regional lymph nodes by their radioactivity. It is used primarily for sentinel lymph node mapping and parathyroid surgery. Radionuclides which uses usually are Tc-99m, I-131 & F-18. Gamma probes can also be used in open surgery, laparoscopy and theroscopy (inside the body), and can be used externally (outside the body). Most use of gamma probes is in Sentinel Lymph Node Biopsy (SLNB) and Radio-Guided Occult Lesion Localization (ROLL). But these systems can be used in all cases where the detection of small points with high activity distribution, high sensitivity and resolution is desired.

Service & Maintenance

The service & maintenance unit of Parto Negar Persia Company has been set up in 2009 at the same time as the beginning of the company's activity, and with the increase of variety and number of products of the company, this section has expanded and methods of responding to customers and customer surveys have been improved.

 Currently, 6 personnel consisting of two senior technical engineers, two technical engineers and two technical technicians are working in this department and provide their services, especially in the field of repair, maintenance and service of nuclear medical imaging systems.

It is also hoped that this year, with the appointment of Dr. Teymourian, with more than ten years of experience in the field of service and maintenance of nuclear medical systems, as the management of the service and maintenance department, the services of this department will be provided with higher speed and quality.

Providing these services in Tehran is less than 24 hours and in other cities is less than 72 hours. Due to the fact that all the products of the company are domestically produced, spare parts for all relevant parts are available in the company and the sleep time of the systems has been reduced to a minimum.
