PK Technology

Powering Gynaecology

PK TECHNOLOGY: Powering Gynaecology

PK TECHNOLOGY is an impedance-controlled bipolar energy system that is designed specifically to enhance performance and versatility in laparoscopic gynecological surgery. It offers a complete range of multifunctional laparoscopic instruments, each individually designed for a specific application area. PK TECHNOLOGY instruments have been established on the market for more than ten years and are used by gynecologists all over the world in various procedures.

The surgeon benefits from:

  • high patient satisfaction and effective performance6
  • potentially shorter procedure times1
  • potentially improved operating-room efficiency1
  • the confidence that comes with ten years proven clinical history

PK TECHNOLOGY System with ESG-400 Generator

PK TECHNOLOGY provides surgeons with the ability to seal, transect, coagulate, dissect, vaporize, resect, and mobilize tissue all with precision and control from one energy platform: ESG-400 - a fully equipped, latest generation HF generator that provides the PK TECHNOLOGY instruments with advanced bipolar energy. An auto-detection function and dedicated sealing and cutting modes for PK TECHNOLOGY instruments and other Olympus devices help simplify the OR workflow.

Clinically Proven for Over Ten Years

PK TECHNOLOGY is an effective technology that has over ten years of proven clinical history and that:

  • is safer than traditional energy technologies, such as monopolar or conventional bipolar2,3,4,5
  • is associated with reduced operation time and high patient satisfaction6
  • eliminates the risk of electrical injury6
  • minimizes thermal damage to the tissue7

PK Cutting Forceps


Clinical Proven and Convincing more than 10 Years

PK Cutting Forceps may shorten procedure times7,8 due to:

  • Reliable coagulation8
  • Controlled and precise mechanical cutting
  • Strong grasping

It is particularly suitable for LSH, TLH, LAVH, and BSO9.

PK Lap Loop


The Lap Loop offers higher patient safety in addition to fast, immediate, and straight cutting of the uterus during LSH procedures10. The gynecologist performing advanced laparoscopic surgery benefits especially from:

  • Patient Safety:
    - Blue-coated wire for optimal visibility in the placement of PK LAP LOOP
    - White ceramic tip helps identifying, if the bowel has been caught in the loop
  • Efficiency:
    - Fast, clean and immediate bipolar cutting
  • Easy and Convenient Handling and Placement:
    - Large loop for big cases
    - Pop-up diamond-shaped loop opens up automatically in the abdomen
    - Consistent loop-shape
    - Ergonomic handle design

PK Spatula


The PK Spatula cuts, coagulates, and dissects with unique bipolar precision, thus allowing for potentially faster procedures and enhanced effectiveness. The tip design allows for both pinpoint and broad tissue coagulation. The PK Spatula is indicated for resection and coagulation of soft tissue and blood vessels in laparoscopic surgery. It is particularly suitable for myomectomy and the amputation of the uterus11.

PK J-Hook


The PK J-Hook can reduce the operating time by cutting and coagulating simultaneously. The unique tip design is excellent for sceletonization and mobilization, thus potentially enabling smooth operation. The PK J-Hook is particularly suitable for adhesiolysis and the amputation of the uterus.

PK Needle


The PK Needle is a unique bipolar cutting device that allows the surgeon to perform precise, safe, and fast procedures. The PK Needle is indicated for resection of soft tissue in laparoscopic surgical procedures. It is particularly suitable for the treatment of ectopic pregnancy, myomectomy, and the amputation of the uterus.
