Endoscope system and method of controlling endoscope system
An endoscope system including an endoscope insertion part to be inserted into a body cavity via a trocar stabbed in a body wall, the endoscope system comprising: a detecting device detecting whether a tip of the endoscope insertion part has been drawn inside the trocar; and a trocar cleaning device cleaning the inside of the trocar by supplying a predetermined fluid into the trocar when it is detected by the detecting device that the tip of the endoscope insertion part has been drawn inside the trocar.
1. An endoscope system comprising:
an endoscope including an insertion part having an observation window at a tip;
a trocar having an insertion path for inserting the insertion part into a body cavity;
a detecting device outputting a detection signal indicating whether or not a tip part of the insertion part is present in the insertion path based on an endoscopic image obtained by the observation window;
a trocar cleaning device determining whether or not to supply a predetermined fluid from a fluid source into the insertion path for cleaning the insertion path based on the detection signal outputted from the detecting device and automatically supplying the predetermined fluid to an inside of the insertion path when it is determined from the detection signal that the tip part of the insertion part is present inside the insertion path; and
an airtight preventive member provided at a proximal end side of the insertion path for ensuring airtightness of the insertion path,
wherein the detecting device automatically detects the insertion part disposed within the insertion path when a distal opening of the tip part is present in the endoscopic image and sends the detection signal to the trocar cleaning device to supply the predetermined fluid to the inside of the insertion path, and
wherein the detecting device automatically detects the insertion part is not disposed within the insertion path when the airtight preventive member is provided in the endoscopic image and sends the detection signal to the trocar cleaning device to stop the supply of predetermined fluid to the inside of the insertion path.
2. The endoscope system according to claim 1 , wherein
the trocar cleaning device intermittently supplies the predetermined fluid to the inside of the insertion path when it is determined by the detection signal that the tip part of the insertion part is present inside the insertion path.
3. The endoscope system according to claim 1 , wherein
the trocar cleaning device supplies the predetermined fluid to the inside of the insertion path by injecting the fluid from an injection nozzle provided at the tip of the insertion part.
4. The endoscope system according to claim 1 , wherein
the trocar cleaning device supplies the predetermined fluid to the inside of the insertion path by injecting the fluid from an injection nozzle provided at a tip of a sheath covering the insertion part.
5. The endoscope system according to claim 1 , wherein
the trocar cleaning device supplies the predetermined fluid to the inside of the insertion path via a fluid introduction port provided at the trocar.
6. The endoscope system according to claim 1 , wherein
the trocar cleaning device cleans the inside of the insertion path by selectively supplying a cleaning solution and a gas into the insertion path.
7. An endoscope system comprising:
an endoscope including an insertion part having an observation window at a distal end;
a trocar having an insertion path for inserting the insertion part into a body cavity;
a detecting device outputting a detection signal indicating whether or not a distal end part of the insertion part is present in the insertion path based on an endoscopic image obtained by the observation window;
a trocar cleaning device determining whether or not to supply a predetermined fluid from a fluid source into the insertion path for cleaning the insertion path based on the detection signal outputted from the detecting device and automatically supplying the predetermined fluid to an inside of the insertion path when it is determined from the detection signal that the distal end part of the insertion part is present inside the insertion path; and
an airtight preventive member provided at a proximal end side of the insertion path for ensuring airtightness of the insertion path,
wherein the detecting device automatically detects that the insertion part disposed within the insertion path when a distal opening of the distal end part is present in the endoscopic image and sends the detection signal to the trocar cleaning device to supply the predetermined fluid to the inside of the insertion path, and
wherein the detecting device automatically detects that the insertion part is not disposed within the insertion path when the airtight preventive member is provided in the endoscopic image and sends the detection signal to the trocar cleaning device to stop the supply of predetermined fluid to the inside of the insertion path.
8. The endoscope system according to claim 7 , wherein
the detecting device outputs the detection signal indicating that the distal end part of the insertion part is present inside the insertion path when a tip opening of the trocar is included in the endoscopic image.
