Gynecology

The BeamPath® GYN system provides Gynecologists with the energy they can trust for safe and complete disease removal.  The device allows the surgeon to operate with confidence near delicate anatomy by providing minimally invasive access, precise and predictable tissue interaction, and the micron-level thermal spread of CO2 laser energy.

The CO2 laser has been considered the gold standard for precise tissue cutting for over 30 years, with a peer reviewed publication base in the thousands.  Although its minimal thermal effect is appreciated when operating near critical structures, clinical applications have historically been limited due to cumbersome set-up and difficulty in obtaining sufficient anatomical access.  OmniGuide has overcome these limitations by introducing BeamPath, a breakthrough technology enabling the delivery of CO2 laser in an easy-to-use, flexible fiber form.

How it Works

Predictable and Precise Tissue Interaction
CO2 laser energy is highly absorbed in water and cuts tissue by vaporizing the water content of cells at the tissue surface. High absorption of CO2 laser energy in water leads to a predictable and controlled tissue interaction with a thermal effect of approximately 150 microns. 1  Electrosurgical energy relies on tissue conductivity, causing a less predictable thermal spread and a tissue effect that is approximately 10x greater. 1 

 

Controlled Depth of Penetration
The BeamPath® System features a divergent beam, allowing the surgeon to easily control the depth of penetration by adjusting the distance to the tissue. Hemostatic cutting is achieved at close distances, while ablation and coagulation is achieved at distances farther away. 

     

Clinical Applications:

Minimally Invasive Endometriosis Procedures
The goal of endometriosis surgery is to give patients the best chance of symptom relief by safely and completely removing disease. Electrosurgery has been widely used in minimally invasive procedures because it enables hemostatic disease resection. However, the thermal spread associated with standard electrosurgery can present safety challenges when working near critical structures like the ureter, bowel, or bladder. In these situations, the risk of thermal injury can prohibit surgeons from complete disease removal.

The CO2 laser offers significant advantages due to its precise and predictable tissue interaction. It is often referred to as the “what you see is what you get” laser. The micron-level thermal effect allows surgeons to visualize depth of penetration, removing the guesswork associated with electrosurgery.

• Key advantages of CO 2 laser in Endometriosis procedures include:

  • SAFETY: precise and predictable tissue interaction minimizes risk of thermal injury 2
  • MORE COMPLETE DISEASE REMOVAL:  micron-level thermal spread 1 allows surgeons to operate with confidence near critical structures like the ureter, bowel, bladder, and reproductive organs

With BeamPath, surgeons can enjoy the benefits of CO2 laser in an easy-to-use, flexible form designed for use in both platforms of minimally invasive surgery:

  • Conventional Laparoscopy – compatible with standard 5mm trocars
  • Robot-assisted Laparoscopy – compatible with robotic instrumentation, allowing full-wristed articulation

Lower Genital Tract Surgery
The CO2 laser is an effective surgical instrument for treating lesions covering a large surface, where precise control over depth of tissue penetration is imperative. Although traditional CO2 lasers provide utility in these procedures, they are limited in anatomical access and are cumbersome to use. In contrast, BeamPath delivers CO2 laser energy to target tissue from any angle while offering no-touch resection and ablation of superficial as well as deep seated vaginal and cervical lesions.
BeamPath offers the following advantages compared to traditional line-of-sight systems:

  • Improved access for hard-to-reach lesions
  • Enhanced ease-of-use and ergonomics
