Example Embodiment

[0029] Example 1, such as Figure 1 to Figure 3 As shown, a new type of intelligent electrocoagulation forceps system includes a forceps body and a host. The forceps body includes a forceps tip 1 and a forceps rod 2. The rear of the forceps rod 2 has an electrode holder 3, and the electrode holder 3 has a plug 4 and a plug 4. The host computer 5 is connected through a cable, and the host computer 5 provides power for the electrocoagulation tweezers through the cable. During use, the host 5 performs real-time detection of the output current and voltage, so as to obtain the real-time impedance of the material between the tweezers tips. Generally speaking, when the blood vessel is first bonded, the impedance between the tips of the forceps is small, and the temperature of the two tips can be higher at this time. As the blood vessels coagulate, the impedance of the material between the two forceps tips gradually increases. At this time, it is necessary to reduce the temperature of...

Example Embodiment

[0036] Example 2: Different from Example 1, the forceps rod also has a suction channel, where the suction channel and the water inlet channel are respectively located inside the two forceps rods, the entrance of the suction channel is located outside the tip of the forceps, and the outlet of the suction channel passes through The second plug interface is connected with the pipe on the suction machine. In this way, when the blood vessel needs to be cleaned, the water inlet channel on the forceps rod on one side flows out, and the suction channel on the forceps rod on the other side sucks blood away.

Abstract

The invention discloses a novel intelligent electric coagulation forceps system which comprises a forceps body and a main machine for supplying power to the forceps body, wherein the forceps body comprises forceps tips and forceps rods. The novel intelligent electric coagulation forceps system is characterized by further comprising a current detection device and a voltage detection device which are used for respectively detecting current and voltage between the forceps tips. Impedance of an object between the forceps tips is calculated according to the ratio of the voltage to the current, and the main machine gradually decreases output power of the forceps tips along with gradual increase of the impedance. A water inlet channel is arranged on the forceps body, an outlet of the water inlet channel is located at the positions of the forceps tips, a first positioning rod is fixed in front of the forceps rod on one side, and a corresponding positioning hole is arranged on the forceps rod on the other side. The temperature of the forceps tips is controlled within a certain range by detecting the temperature of the forceps tips in real time, so that adhesion effect of the electric coagulation forceps is ensured, and a superheat phenomenon is avoided.

Description

technical field [0001] The invention relates to a surgical instrument for transferring non-mechanical energy to the human body by passing electric current through tissue to be heated. Background technique [0002] The existing electrocoagulation tweezers system includes a tweezers body and a host that provides power and control for the tweezers body. The tweezers body sequentially includes tweezers tips, an insulating tweezers rod and an electrode holder. The plug at the rear of the electrode holder is connected to an external host through a wire. The tweezers tip of electrocoagulation tweezers provides high-frequency electric energy to the lesion tissue to dehydrate and coagulate the protein between the two ends of the tweezers tip to achieve the purpose of hemostasis. Because its range of action is limited to between the two tweezers, the degree of damage and range of influence on adjacent tissues is very small, and it is quite safe. [0003] During the use of traditi...
