Problems solved by technology

However, there is a disadvantage that the pressure of the gas in the abdominal cavity decreases due to suction, and therefore new carbon dioxide gas needs to be delivered from the gas storage tank used as the gas supply source, thereby increasing the consumption of carbon dioxide gas
[0005] The above-mentioned conventional example is a structure in which the extracted carbon dioxide gas as a predetermined gas is circulated and reused, so the consumption of carbon dioxide gas can be reduced, but it cannot cope with the situation where a large amount of smoke is generated in the abdominal cavity.

no. 1 approach

[0037] Such as figure 1 As shown, the endoscopic surgery system 1 includes an electric scalpel device 4 as a surgical device, an endoscope device 6 , and the pneumoperitoneum device 8 of the first embodiment. The patient 3 who is the subject of the bed 2 performs surgery, the endoscope device 6 is used to observe the surgical operation using the endoscope 5, and the pneumoperitoneum device 8 makes the abdomen 3a to be operated in a pneumoperitoneum state to ensure endoscopy. The field of view of the mirror 5 and the area where the electric scalpel 7 is used for surgery. In addition, it can also be defined as an object in which the abdomen 3 a is formed.

[0038] The electric scalpel device 4 includes an electric scalpel power supply device 11 that generates high-frequency power, and an electric scalpel 7 that is supplied with the high-frequency power generated by the electric scalpel power supply device 11 via a cable 12, and is set by the operator through operation. The sw...

[0124] Next, a second embodiment of the present invention will be described. Figure 11 A pneumoperitoneum device 8E according to a second embodiment of the present invention is shown. The pneumoperitoneum device 8E is in Figure 2B The pneumoperitoneum device 8A is equipped for use in Figure 9 The device main body 21 of the third electromagnetic valve 53 is replaced by the check valve 74 described in FIG. In addition, in this embodiment, do not use Figure 2B The characteristic detection circuit 63 includes means for detecting a decrease in the filter characteristic of the filter 56E.

[0125] Figure 12 The structure near the suction nozzle base 29 in this embodiment is shown. Figure 12 (A) shows the structure near the suction nozzle base 29, Figure 12 (B) shows a filter 56E detachably attached to the recessed portion of the suction nozzle head 29 .

[0126] In the first modified example of the first embodiment, the suction nozzle head 29 is configured to have a tw...

Abstract

The pneumoperitoneum apparatus comprises: a gas feed duct connection part for connecting a duct for delivering a specified gas into a subject; a first duct for connecting a gas feed source connection part to the gas feed duct connection part; a suction duct connection part for connecting a duct for sucking out the specified gas from inside the subject; a pump for circulating the specified gas to the subject; a circulation duct for connecting the suction duct connection part to the pump; a second duct for connecting a suction source connection part to the circulation duct; a control section for controlling a switching unit so that the device operates in a first operation mode in which the specified gas is circulated to the subject via the pump and a second operation mode in which the specified gas is sucked to the suction source side via the second duct; etc.

Description

technical field [0001] The invention relates to an insufflation device for making the body cavity in an insufflation state. Background technique [0002] In recent years, surgical operations performed under observation through a laparoscope have been widely used. In surgical operations performed using a laparoscope, a pneumoperitoneum device is used to deliver a predetermined gas such as carbon dioxide gas into the abdominal cavity to secure a field of view of the laparoscope and a region for performing surgery. [0003] In addition, in the case of treatment with an electric scalpel, smoke generated in the abdominal cavity may hinder observation, so the smoke generated in the abdominal cavity is sucked by a suction device and discharged to the outside of the abdominal cavity. However, there is a disadvantage in that the pressure of the gas in the abdominal cavity decreases due to suction, and therefore new carbon dioxide gas needs to be fed from the gas storage tank used as...
