A Lumbar Set (also called a Lumbar Laminectomy or Spinal Set) is a specialized collection of surgical instruments used in neurosurgical or orthopedic procedures involving the lumbar spine, such as laminectomy, discectomy, or decompression surgeries. The set is designed for precise bone removal, nerve decompression, and tissue handling around the spine.

Key Components and Their Functions:

1. Scalpel Handle with Blades – For making abdominal and uterine incisions.

2. Mayo Scissors (Straight & Curved) – Used to cut tissues, fascia, and sutures.

3. Metzenbaum Scissors – For delicate dissection of soft tissue.

4. Artery Forceps (Mosquito, Crile, Kocher) – For clamping blood vessels and controlling bleeding.

5. Tissue Forceps (Allis, Babcock, Toothed & Non-Toothed) – Used to grasp tissues and the uterus gently.

6. Needle Holders (Mayo-Hegar) – To hold and guide needles during uterine and skin closure.

7. Retractors (Doyen, Deaver, Langenbeck) – For exposing abdominal layers and uterus.

8. Sponge Holding Forceps – To hold gauze or sponges for cleaning or mopping.

9. Uterine Sound and Vulsellum Forceps – To manipulate and stabilize the uterus.

10. Bowl and Basin Set – For antiseptic solutions and irrigation fluids.

A Manual Craniotomy Drill is a hand-operated surgical instrument used to create openings in the skull (burr holes) during a craniotomy procedure. It allows surgeons to penetrate the cranial bone safely and precisely without causing damage to the underlying brain tissue.

The 400-watt electrosurgical unit (ESU) is a microprocessor-controlled device that provides both monopolar and bipolar modes of operation. It can deliver a maximum output power of 400 watts, making it suitable for a wide range of surgical applications—from minor soft-tissue procedures to major operations requiring deep tissue cutting.

The machine allows precise adjustment of power levels, automatic load detection, and patient safety monitoring. It comes with cutting and coagulation modes, each optimized for smooth surgical performance and reduced tissue damage.

This unit delivers up to 300 watts of output power, making it suitable for general, gynecological, ENT, orthopedic, and minor surgical procedures. It converts electrical energy into heat, enabling precise tissue dissection and coagulation with minimal damage to surrounding tissues.

The machine typically includes monopolar and bipolar modes, allowing flexibility in various surgical applications. It features a microprocessor-based control system for accurate power output and enhanced patient safety.
