Surgical operation system as well as unipolar and bipolar hybrid output method thereof

Abstract

The present invention provides a surgical operation system as well as a unipolar and bipolar hybrid output method thereof. The method is applied to the surgical operation system and includes the stepsof determining a selection instruction of an operator for output modes and controlling a first execution instrument to execute a cutting action and a tissue coagulation action when acquiring an instruction of selecting a unipolar and bipolar hybrid mode. The system includes a main control unit, a control panel, a high-frequency power supply module and the execution equipment. The surgical operation system can realize the hybrid mode of unipolar mode cutting and bipolar mode coagulation through the same execution instrument, not only overcomes the respective shortcomings of conventional unipolar output and conventional bipolar output, but also integrates the respective advantages of unipolar output and bipolar output.

Description

Technical field [0001] The invention relates to the technical field of electrosurgery, in particular to a surgical operating system and a single and bipolar hybrid output method applied to the system. Background technique [0002] The electric knife uses the energy output from the electrosurgery system to cut and coagulate human tissues. Among them, the thermal effect of the electric current will cause the body tissue to vaporize, which is the principle of cutting; the thermal effect of the electric current will make the human tissue protein denature and coagulate, which is the principle of blood coagulation. [0003] At present, electrosurgery systems generally have the functions of unipolar output and bipolar output. [0004] In the existing technology, such as figure 1 As shown, figure 1 It is a working mode of the unipolar output function of an existing electrosurgery system. The electrosurgery system includes a high-frequency power supply module, an electrosurgical pen, a loop ...

AI Technical Summary

Problems solved by technology

[0007] However, since the electric knife pen is only one pole in the entire current circuit, the electric power cannot be concentrated on the tissue to be coagulated to a large extent, but reaches the negative plate end through the larger area of ​​human tissue after passing through the pen tip.

Therefore, its coagulation effect is worse than that of the bipolar electrotome; and it is difficult for the monopolar electrosurgical pen to go deep into the abdominal cavity for minimally invasive surgery under laparoscope; Only high power can cut the tissue, but the high power brings great thermal damage to the tissue

[0008] Advantages and disadvantages of bipolar output: Since the coagulated tissue is the tissue that needs to be coagulated and is sandwiched between the two poles, the electric power is concentrated in the tissue between the two poles to a large extent.

[0009] However, since the energy output of bipolar instruments (bipolar scissors or bipolar forceps, bipolar forceps) is generally smaller than that of unipolar instruments, and the tissue energy density between the position of the upper blade and the lower blade is smaller than that of the tip of the monopolar electric knife pen , so when cutting thicker tissues, it is difficult to achieve rapid vaporization and separation of tissues

Therefore, bipolar instruments (bipolar scissors or bipolar forceps, bipolar forceps) are often only able to cut thin tissue
