Problems solved by technology

[0008] There are still some flushing and suction devices for endoscopes that use a three-way switch. When the switch is rotated to one position, it is suctioned, and when it is rotated to another position, it is flushed, but it is quite difficult to operate with one hand.

Abstract

The invention discloses a multifunctional cutting and sucking knife for an endoscope. The multifunctional cutting and sucking knife combines an aspirator and an electrotome into a whole. When the surface of a wound has a bleeding phenomenon, the surface of the wound can be rinsed and sucked in time, tool replacement is not needed, therefore, operation time is saved, and the amount of bleeding is reduced. The multifunctional cutting and sucking knife comprises the electrotome and a suction pipeline, wherein the front end of the suction pipeline is provided with an opening in a beveling mode. One end of the electrotome extends from the opening by 2-3mm. The other of the electrotome is connected to a power supply through an electrode wire. The width of the electrotome is equal to the inner diameter of the suction pipeline. The rear end of the suction pipeline is provided with a suction opening and a water inlet. The suction opening is connected with a suction device, and the water inlet is connected with a rinsing device. The suction device is controlled by a suction button on the suction pipeline, and the rinsing device is controlled by a rinsing button on the suction pipeline. All mist generated by the electrotome falls in a suction region of the suction pipeline.

Description

technical field [0001] The invention relates to a multifunctional cutting and suction knife for endoscope. It belongs to the technical field of medical equipment. Background technique [0002] In conventional laparoscopic surgery, the suction device and the electric knife are used separately, which is not convenient enough to operate. When the wound surface is bleeding, or the contents of the gastrointestinal tract or biliary tract overflow, the operation cannot be continued, and a flushing device is required at this time. Flushing undoubtedly prolongs the operation time and increases the amount of bleeding. [0003] In addition, laparoscopic surgery is different from traditional open surgery. It only cuts a few 1-2cm holes in the abdominal wall, inserts lenses and instruments, and performs surgery by displaying the situation in the abdominal cavity through a monitor. [0004] Most of the current laparoscopic operations need to inject carbon dioxide gas into the abdominal ...
