Front end structure of electrocoagulation forceps

Abstract

The invention discloses a front end structure of electrocoagulation forceps. The front end structure comprises a forceps head, a forceps rod which is connected with the forceps head and drives the forceps head to be opened and closed through axial movement, a forceps handle which is connected with the forceps rod and drives the forceps rod to move axially, and a handle; the front end of the handle is connected with a handle tube; the handle tube comprises a hard tube section of which the rear end is fixed to the handle, a bendable section coaxially fixed to the front end of the hard tube section, and a hard fixed shaft section coaxially fixed to the front end of the bendable section; the forceps head is rotatably and coaxially connected to the front end of the fixed shaft section; and a rotation driving mechanism for driving the forceps head to rotate around the fixed shaft section and a bending driving mechanism for driving the bendable section to bend are arranged in the handle. By means of bidirectional bending of the bendable section of the front section of the handle tube and rotation of the forceps head, the pair of electrocoagulation forceps has various operation angles, handle tube turning, head rotating and clamping functions can be achieved at the same time, the pair of electrocoagulation forceps is convenient to use under the condition of complex cavities, and relatively large tissue damage cannot be caused.

Description

technical field [0001] The invention relates to the technical field of electrocoagulation forceps, in particular to a front end structure of electrocoagulation forceps. Background technique [0002] In laparoscopic clinical surgery, although the trauma is small, blood vessels will inevitably be cut and local bleeding will occur during the operation. The traditional method of thread tying to stop blood is not very suitable for laparoscopic surgery. The method of coagulation to stop bleeding is widely used. The use of electrocoagulation for surgical hemostasis originated very early, and the current used for surgery is high-frequency current (the frequency is thousands of cycles per second to more than 2 megacycles). Apply high-frequency current, even if the voltage is as high as thousands of volts, it can safely pass through the human body without causing nerve or muscle reactions. Through the thermal effect of high-frequency current, the blood vessel wall is dehydrated and ...

AI Technical Summary

Problems solved by technology

[0003] However, when the existing bipolar electric coagulation forceps are used, the operating angle of the electric coagulation forceps is limited, and it is difficult to use in complex cavity conditions, which will cause greater tissue damage
