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

  • In a minimally invasive surgical procedure in the abdomen, such as removal of the gallbladder, access is required to allow instruments to be placed in the abdomen. Trocars (access cannulas) are used for this purpose, which are inserted into the abdominal wall and allow the body cavity to be dilated using CO2 gas. The CO2 gas creates an overpressure in the abdominal cavity. This causes the abdominal wall to rise, creating the free space needed for the procedure.
  • The trocar is connected to the insufflator by a sterile tube. The insufflator pumps up to 50 liters of CO2 per minute (l/min) into the abdominal cavity, depending on the application. The gas is heavily contaminated during the surgical procedure, i.e. by high-frequency coagulation resulting in heavy smoke formation. The insufflator continuously exchanges the contaminated CO2 gas by active suction of up to 12 l/min, thus ensuring a clear view of the surgical field.
  • Our 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.
  • We offer two unique & patented software algorithms supporting value-based & personalized healthcare and increased patient safety:
    • ISI (Intelligent Steady Insufflation)™ continuously monitors & forecasts pressure to keep surgical conditions in the abdomen stable. It provides a steady flow without interrupting workflows, even under challenging conditions.
    • This will be supported with IPM (Intelligent Pressure Monitoring)™ by increasing pressure accuracy within the pneumoperitoneum and avoiding potentially harmful overpressure situations for the patient without impacting performance of the insufflator.

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.
  • 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

  • Like insufflators, our suction/irrigation pumps enable the distension of various body cavities while ensuring optimal pressure & visibility conditions throughout the surgical procedure.
  • Our devices are used for procedures on the uterus (hysteroscopy), joints (arthroscopy) and urethra, bladder, ureter and kidney (endourology).
  • Saline or sugar solutions are used to distend the body cavities. The pump provides a reliable pressure build-up while simultaneously irrigating or aspirating fluid.
  • To improve patient safety and ensure a superior reliability, our newest pump generation offers a unique & patented software algorithm enabling virtual pressure monitoring within body cavities - IPM (Intelligent Pressure Monitoring)™. This algorithm increases pressure accuracy and avoids potentially harmful overpressure situations for the patient without reducing performance during minimally invasive procedures.
