    摘要: According to one embodiment, a method includes positioning a portion of a trocar into a patient cavity and inserting a surgical instrument into the trocar. The method also includes measuring, by a pressure sensor disposed in, on, or through a medical appliance, a pressure indicative of a pressure in the patient cavity. The method also includes supplying, based at least in part on the measured pressure, an insufflation gas to the patient cavity by providing the insufflation gas through the trocar.

    摘要: According to one embodiment, a method includes providing a trocar having a flow path for passage of an insufflation gas and also having a region outside the flow path that is open at the distal end of the trocar. The method also includes supplying insufflation gas through the flow path of the trocar and determining a differential pressure between a first pressure in the flow path of the trocar and a second pressure in the region of the trocar outside the flow path. The method also includes controlling the supply of insufflation gas through the trocar based at least in part on the determined differential pressure.

    摘要: According to one embodiment, a method includes positioning a portion of a trocar into a patient cavity and inserting a surgical instrument into the trocar. The method also includes measuring, by a pressure sensor disposed within the trocar, a pressure within the trocar. The measured pressure is indicative of a pressure in the patient cavity. The method also includes supplying, based at least in part on the measured pressure, an insufflation gas to the patient cavity by providing the insufflation gas through the trocar.

    摘要: A method includes receiving, from a primary pressure sensor, a pressure measurement indicative of a pressure of a patient cavity and controlling, by an insufflator, a supply of the insufflation fluid to the patient cavity based on the pressure measurement from the primary pressure sensor. The method further includes delivering, by a trocar, the supplied insufflation fluid to the patient cavity via an access port, wherein: the access port comprises a seal and a retractor; and the access port facilitates access therethrough to the patient cavity.

    摘要: A method comprises positioning a medical appliance having a primary pressure sensor at or within a patient incision site and supplying an insufflation fluid to the patient cavity. The method further comprises measuring a pressure in the patient cavity by the primary pressure sensor and controlling the supply of insufflation fluid by an insufflator to the patient cavity based at least on the measured pressure. The method further comprises determining, by a processor associated with the insufflator, that the measured pressure may be inaccurate and, in response to determining that the measured pressure may be inaccurate, controlling, by the insufflator, the supply of the insufflation fluid to the patient cavity based at least on a pressure measured by a backup pressure sensor.
