Problems solved by technology

However, the existing bipolar electrocoagulation and electric cutting instruments under endoscopy are all foot-controlled, which is not easy to operate during the operation (the surgeon needs to move the center of gravity and lift the foot, causing the instrument to shake; there are multiple pedals such as monopolar and ultrasonic scalpels under the foot, which are easy to confuse ), if bipolar coagulation can be conveniently operated by hand, it can improve the experience of surgeons

Embodiment 1

[0048] Such as figure 1 As shown, a manual excitation type bipolar electrocoagulation cutting instrument can be used as a high-frequency surgical forceps, which includes an instrument body, and the instrument body includes:

[0049] High-frequency energy supply components;

[0050] The electrocoagulation cutting part is connected with the high-frequency energy supply part and is suitable for acting on human tissue and realizing electrocoagulation on human tissue when high-frequency energy is supplied;

[0051] A manual control part connected with the high-frequency energy supply part and suitable for manual operation to switch on or off the high-frequency energy flowing into the electrocoagulation cutting part.

[0052] Specifically, as figure 1 As indicated, the instrument body also includes:

[0053] fixed handle 7;

[0054] The casing assembly 3, the tail end of the casing assembly 3 is connected to the fixed handle 7, and the electrocoagulation cutting part is movably ...

Embodiment 2

[0084] The structure of the manual excitation type bipolar electrocoagulation cutting instrument of this embodiment is basically the same as that of Embodiment 1, the difference is: as figure 2 , 3 As shown, the electrocoagulation cutting unit is a scissors unit; the scissors unit includes a first scissors arm 1 a and a second scissors arm 1 b adapted to move closer to or spread apart under the movement of the push rod 2 . The scissors part of this embodiment can realize the function of electric cutting or the function of cutting while coagulating.

[0085] The first scissor arm 1a and the second scissor arm 1b are hinged and jointly hinged on the head end of the sleeve assembly 3, and the hinge forms a hinge point G;

[0086] The head end of the push rod 2 can be hinged to the first scissor arm 1a and the second scissor arm 1b through a link mechanism.

[0087] Specifically, the link mechanism may be the following structure, which includes a first link 1c and a second link...

Abstract

The invention discloses a manual excitation type bipolar electrocoagulation cutting instrument. The manual excitation type bipolar electrocoagulation cutting instrument comprises an instrument main body; the instrument main body comprises a high-frequency energy supply part, an electric coagulating and cutting part and a manual control part; the electric coagulating and cutting part is connected with the high-frequency energy supply part, and is suitable for acting on human tissues and realizing electric coagulating and/or electric cutting on the human tissues when high-frequency energy is supplied; and the manual control part is connected with the high-frequency energy supply part and is suitable for being manually operated to connect or disconnect the inflow of the high-frequency energy into the electric coagulating and cutting part. According to the manual excitation type bipolar electrocoagulation cutting instrument, manual control excitation can be achieved under an endoscope, gravity center instability and shaking caused by the fact that a surgeon needs to step on a pedal in the surgery are avoided, control is easier, misoperation and accidental injury are not likely to happen, and the use experience of the surgeon in the surgery is improved.

Description

technical field [0001] The invention relates to a manually activated bipolar electric coagulation cutting instrument. Background technique [0002] Laparoscopic surgery (including laparoscopic, thoracoscopic and other endoscopic-based surgery) is one of the greatest advances in medicine in the 21st century. A series of difficult and complicated operations such as radical gastrectomy and radical gastrectomy can now be carried out under laparoscopy. While laparoscopy brings advantages such as minimally invasive, magnified and clear field of view, it also brings the problem of difficult control of intraoperative bleeding. Bipolar coagulation has the advantages of precise hemostasis, low ambient temperature, and less side damage in controlling bleeding. However, the existing bipolar electrocoagulation and electric cutting instruments under endoscopy are all foot-controlled, which is not easy to operate during the operation (the surgeon needs to move the center of gravity and l...
