Abstract

Devices and methods are provided for removing fluid from a surgical access device and / or from surgical instruments passed therethrough, and for preventing such fluid from accumulating. For example, in one embodiment, an exemplary device can include a body defining a working channel that is configured and sized to allow for passage of a surgical instrument therethrough. A number of seals can be disposed in the working channel so as to contact the inserted surgical instrument. One or more outlets can be oriented to direct gas, such as air or an insufflation gas, into the working channel so as to remove fluid on the seals, or other parts of the surgical access device, as well as the surgical instruments themselves. In some embodiments, constant flows of gases can be arranged to act as shields to help prevent fluid from accumulating on the surgical access device and / or surgical instruments.

Description

technical field [0001] The present invention generally relates to devices and methods for removing fluid from a surgical access device and / or from surgical instruments passing through the surgical access device, as well as devices and methods for preventing such fluid accumulation. Background technique [0002] In laparoscopic surgery, one or more small incisions are made in the abdomen and a trocar is inserted through the incisions to create access to the abdominal cavity. A trocar is used to introduce various instruments and tools into the abdominal cavity and to provide insufflation to elevate the abdominal wall above the organs. During the procedure, a scope device such as an endoscope or laparoscope is inserted through one of the trocars to allow the surgeon to view the surgical field on an external monitor connected to the scope device. [0003] Mirror devices are often inserted and removed through the trocar multiple times during a single surgical procedure, and duri...
