INTERNALLY PRESSURIZED MEDICAL DEVICES |
摘要 |
There are provided pressurized surgical instruments for use in pressurized surgical environments. The pressurized surgical instruments include pressurizing systems for maintaining a neutral or positive pressure flow within the surgical instrument during use. The pressurizing systems include a primary sensor for detecting the pressure of the surgical environment and a pressurizing mechanism for balancing the pressure of the surgical instrument with the surgical environment. The pressurizing mechanism includes a controller to receive and compare the signal sent from the primary sensor to the ambient or internal instrument pressure and a pressure delivery system to provide positive pressure to the interior of the surgical instrument in response to a signal received from the controller. The sources of pressure for the pressure delivery systems may be external or self contained within the surgical instrument.
