Problems solved by technology

[0003] During the use of traditional electrocoagulation tweezers, the output power of the electrocoagulation tweezers is fixed, which may cause the temperature of the tip of the tweezers to be too high, causing the problem of burning blood vessels, and when using it, it is necessary for personnel to constantly Squeeze the tweezers so that the two tweezers touch
Due to the long tweezers shaft, the contact of the tweezers tips is often misaligned, causing problems in use

Embodiment 1

[0029] Example 1, such as Figure 1 to Figure 3 As shown, a new type of intelligent electrocoagulation tweezers system includes a tweezers body and a host, wherein the tweezers body includes a tweezers tip 1 and a tweezers rod 2, the rear part of the tweezers rod 2 has an electrode seat 3, and the electrode seat 3 has a plug 4, and the plug 4 It is connected with the host 5 through a cable, and the host 5 provides power for the electric coagulation forceps through the cable. During use, the host 5 detects the output current and voltage in real time, so as to obtain the real-time impedance of the material between the tweezers. Generally speaking, at the beginning of blood vessel bonding, the impedance between the tweezers is small, and the temperature of the two tweezers can be higher at this time. With the coagulation of blood vessels, the impedance of the material between the two tweezers gradually increases. At this time, it is necessary to reduce the temperature of the twe...

Embodiment 2

[0036] Embodiment 2: Different from Embodiment 1, there is also a suction channel on the tweezers rod, wherein the suction channel and the water inlet channel are respectively located inside the two tweezers rods, the entrance of the suction channel is located outside the tweezers tip, and the outlet of the suction channel passes through The second socket is connected with the pipeline on the suction machine. In this way, when the blood vessels need to be cleaned, the water inlet channel on one side of the tweezers flows out the water flow, and the suction channel on the other side of the tweezers sucks away the blood.

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...
