The light source device 4 is connected to a first endoscope camera 7 via a light guide cable 8 that transmits illumination light. When the illumination light of the light source device 4 is supplied to the light guide cable 8 of the endoscope camera 7, the affected part in the abdomen of the patient 15 into which the insertion portion of the endoscope camera 7 is inserted is illuminated. .

  Optical image data captured by the endoscope camera 7 is transmitted to the video processor 3 via the imaging cable 9. The optical image data is signal-processed by a signal processing circuit in the video processor 3 to generate a video signal. The video signal is output to the display device, and an endoscopic image is displayed.

  Trocars 10 a and 10 b are punctured in the abdominal cavity of the patient 15. An insufflation tube 11 extending from the insufflation apparatus 5 is inserted into the trocar 10a and introduced into the abdominal cavity.

<Second Embodiment>
The insufflation algorithm of the insufflator is only an algorithm that matches the size of the abdominal cavity. However, when air is delivered to a cavity smaller than the abdominal cavity, overshoot often occurs.

Therefore, in this embodiment, a description will be given of an air supply algorithm for a small cavity that is adapted to the size of a cavity that is smaller than the abdominal cavity.
In the air supply algorithm for the small cavity, the maximum air supply pressure is set lower than that of the air supply algorithm for the abdominal cavity (for example, 30 mmHg).

Further, in the air supply algorithm for the small cavity, when the flow rate measured at the time of air supply is lower than the air flow algorithm for the abdominal cavity, the process for increasing the air supply pressure is not performed.
In addition, the algorithm for the abdominal cavity provides a process to observe the situation by weakly supplying air at the start of air supply. However, the algorithm for the small cavity always performs weak air supply. do not do.

<Third Embodiment>
Currently, in an endoscopic procedure, the target cavity is inflated with air or carbon dioxide gas in order to secure a surgical field and a working space. When the target cavity is inflated, air is supplied via the air / water supply channel of the endoscope by manually pressing the air / water supply button of the endoscope.

  However, in recent years, with the diversification and complexity of endoscopic procedures (for example, ESD and NOTES), inconvenience has arisen in securing the visual field by manual operation. ESD is an abbreviation for Endoscopic submucosal dissection. NOTES is an abbreviation for Natural Orifice Translumenal Endoscopic Surgery.

  Therefore, in this embodiment, it is possible to automatically control the air supply to secure the surgical visual field, reduce the man-hour for the operator to secure the visual field, and concentrate on the technique (operation of the endoscope and forceps). Like that.

  FIG. 6 shows an endoscope system according to the third mode for embodying the present invention (embodiment 1). The endoscope system includes an insufflation apparatus 80, an endoscope 81, an insufflation tube 82, and a forceps channel 83.

In this embodiment, an air supply device 80 is connected to the forceps channel 83 and air is supplied to the air supply object 84 through the endoscope 81.

  According to the present embodiment, the forceps channel having the largest inner diameter (wide space) among the channels of the endoscope is used to perform fluid supply and pressure sensing. As a result, air can be supplied at a high output flow rate even under an endoscope, and pressure sensing can be performed with a fast response.

  FIG. 7 shows an endoscope system according to the third mode for embodying the present invention (embodiment 2). That is, as shown in FIG. 7, a forceps can be inserted into the forceps channel by connecting a T-shaped tube 86 between the forceps channel of the endoscope and the pneumoperitoneum tube. Example 2 improves Example 1 and enables air supply with forceps inserted into the channel. In FIG. 7, the lower part of the T-shaped tube 86 is connected to forceps, and a tube extending in the lateral direction of the T-shaped tube 86 is connected to an insufflation tube 82 extending from the insufflation apparatus 80. Moreover, the forceps 87 can be inserted from the upper part of the T-shaped tube. Note that the connection method between the T-shaped tube 86 and the pneumoperitoneal tube 82 is preferably a luer shape or a bamboo shoot shape.

  The present invention is not limited to the above-described embodiment, and various configurations or embodiments can be taken without departing from the gist of the present invention.
