Embodiment 1

[0034] refer to figure 1 , is a multifunctional electric knife for laparoscopic surgery disclosed by the present invention, which includes an operating handle 1 made of insulating material. The interior of the operating handle 1 is hollow and the head end and tail end of the operating handle 1 have openings. A suction tube 2 is arranged at the head end of the operating handle 1, and the suction tube 2 is a silicone tube. One end of the suction tube 2 extends into the inside of the operating handle 1 through the opening at the head end of the operating handle 1 , and the other end is located outside the operating handle 1 .

[0035] One end of the suction tube 2 outside the operating handle 1 is the suction end of the suction tube 2 , and the suction tube 2 is fixedly connected to the operating handle 1 . The tail end of the operating handle 1 is provided with a pipe joint 3 , one end of the pipe joint 3 extends into the interior of the operating handle 1 through the opening a...

Embodiment 2

[0044] refer to Figure 5 , is a multifunctional electric knife for laparoscopic surgery disclosed in the present invention. The difference between Embodiment 2 and Embodiment 1 is that the communication channel used to connect the suction tube 2 and the pipe joint 3 is a connecting tube located inside the operating handle 1 7. One end of the connecting pipe 7 is connected with the end of the pipe joint 3 extending into the operating handle 1, and the other end is connected with the part of the suction pipe 2 extending into the operating handle 1. All are fixed and sealed connections. The part where the connecting pipe 7 is connected with the suction pipe 2 is located at one end of the suction pipe 2 close to the telescopic section 21 . In this embodiment, the connecting pipe 7 is a hose.

[0045] During laparoscopic surgery, the electric knife can be used to cut the blood at any time while keeping the anatomical surface clear, greatly improving the quality of the operation...

Abstract

The invention relates to a multifunctional electrotome for laparoscopic surgery. The multifunctional electrotome comprises an operating handle, a needle-shaped electrode and an electric control module, the interior of the operating handle is hollow; a sliding block capable of sliding back and forth is arranged in the operating handle; a suction tube is fixed at the head end of the operating handle; a pipe joint is arranged at the tail end of the operating handle; a telescopic section with an adjustable length is arranged at the position, located in the operating handle, of the suction tube, the needle-shaped electrode is located in the suction tube and fixedly connected with the sliding block, a control mechanism for controlling the sliding block to move is arranged on the operating handle, and a communication channel for communicating the suction tube with the tube pipe joint is arranged in the operating handle. The electrotome and an aspirator do not need to be frequently and repeatedly replaced in the operation process, a lot of precious time is saved, bleeding can be sucked away at any time while cutting is conducted, an anatomical surface is always kept clear, the operation quality is improved, and finally the bleeding amount in the operation is reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a multifunctional electric knife for laparoscopic surgery. Background technique [0002] When laparoscopic cholecystectomy is performed for acute cholecystitis, the operative field is prone to bleeding due to acute inflammation, resulting in blurred operative field. Traditional treatment methods: At present, during laparoscopic surgery, there are tools such as electric hooks and electric rods. These tools can only perform electrocution and electrocoagulation, but cannot attract at the same time. After exhaustion, the suction device is removed, and then inserted into the electric knife for cutting. This kind of conversion often delays time. When the suction device is taken out and the electric knife is re-entered, the operative field will be blurred by bleeding again, and the effect is not good. This process is repeatedly operated, which increases the difficulty of t...
