Space for safe Procedures – Insufflators & Pumps

In Minimally Invasive Medicine, good visibility and precise incisions are the nuts and bolts. However, both are only possible when there is enough space for the scope and medical instruments. Insufflators and Pumps are needed to dilate body cavities reliably with medical CO2 or fluid for stable internal surgical sites. WOM is the global leader and pioneer for Insufflators in the field of laparoscopy and for Pump systems in the field of gynecology.

Providing a working Space: Insufflators

Insufflator
  • During a surgical procedure in the abdominal cavity, such as the removal of the gallbladder, space must be created first. This is done through a hollow tube called a trocar, which is gently pushed through the abdominal wall and anchored in place so no CO2 is released
  • The sterile tubing of an Insufflator is connected to the trocar. Depending on the application, up to 50 liters of gas per minute (l/min.) can be supplied and up to 12 l/min. can be extracted
  • This innovative CO2 management makes it possible to keep surgical conditions in the abdomen very stable and the risks for the patient low at the same time. The pressure is high enough to provide adequate visibility and space in the body cavity, but also low enough so that no large quantities of CO2 reach the bloodstream (embolism)

Insufflation in Cardiac Surgery

  • Surgical teams also use our Insufflators in cardiac surgery for harvesting a vessel in cardiac surgical mode
  • Harvesting involves the surgeon gently removing a vessel from the patient's arm or leg that is later used for the heart bypass. Read more about this in the article about the instrument developed by WOM
  • In cardiac mode, the Insufflator creates an optimal CO2 environment in the opened chest cavity, for example, when replacing heart valves, to minimize ambient air reaching the vessels (risk of embolism)

Pressure Equalization through innovative Pump Systems

Pump
  • Our Pump systems also produce optimal pressure conditions for surgery in body cavities
  • Unlike Insufflators, the Pumps work with saline or dextrose solutions
  • Our devices are used for procedures in the uterus (hysteroscopy), joints (arthroscopy), and urethra, bladder, ureter, and kidney (endourology)
  • The Pump reliably builds pressure where needed and even maintains it when simultaneously irrigating or extracting fluid
