Description

A New Intelligent Coagulation Tweezer System

technical field

The present invention relates to a surgical instrument that transmits non-mechanical energy to the human body by passing an electric current through the tissue to be heated.

Background technique

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.

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. Squeeze the tweezers so that the two tweezers touch. Due to the long tweezers shaft, the contacts of the tweezers tips are often misaligned, causing problems during use.

Both ends of the limiting rod are convex, and are stuck on the outer sides of the two tweezers.

The invention controls the temperature of the tweezers within a certain range by detecting the impedance between the tweezers in real time, thereby ensuring the bonding effect of the electrocoagulation tweezers and avoiding the occurrence of overheating. The water inlet channel and the suction channel set on the tweezers body are located at the tip of the tweezers. When the surgical site around the blood vessel needs to be cleaned, the water inlet channel drains outward, and the suction channel sucks out the blood, which can be timely and more thorough. Clearing the operation site greatly facilitates the doctor's operation.

At the same time, the present invention is equipped with a positioning rod and a limit rod on the tweezers body. The limit rod can be used for coarse positioning, and at the same time prevents damage to the tweezers due to misuse. The positioning rod is for fine positioning, which can accurately ensure the accuracy of positioning.

The electrocoagulation tweezers support provided by the present invention has a simple structure, and after the electrocoagulation tweezers are used, they can be directly inserted into the grooves on the support, and the flexible material in the grooves tightly wraps the tweezers tips. When using again, just take out the electrocoagulation tweezers and use it directly, and like this, the cleaning of the tweezers tips is automatically realized through the friction between the flexible material and the tweezers tips. Moreover, after each use, the wheel will automatically rotate to replace the groove at the opening of the support to prevent cross-infection.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the present invention will be further described.

Embodiment 1, as shown in Figures 1 to 3, 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, and the rear portion of the tweezers rod 2 has an electrode seat 3, There is a plug 4 on the electrode base 3, and the plug 4 is connected to the host 5 through a cable, and the host 5 provides power for the electrocoagulation 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 tweezers to prevent the blood vessels from burning due to excessive temperature.

One side of the tweezers tip 1 and the tweezers rod 2 are provided with a water inlet channel 6, wherein the outlet of the water inlet channel 6 is located outside the tweezers tip, and the inlet is located on the electrode holder 3, and has a first socket matching the water storage device 7.

A first positioning rod 8 is fixed on the front part of the tweezers rod on one side, and a corresponding positioning hole 7 is provided on the other side of the tweezers rod. The middle part of the tweezers rod is provided with a limit rod 10, which passes through the limit holes on the tweezers rods on both sides, wherein the two ends of the limit rod are convex insulating caps 9, which are stuck on the outsides of the two tweezers rods.

When in use, the limit rod 10 limits the maximum opening of the tweezers rod, and also roughly positions the tweezers. When pinching the tweezers bar, the tip of the tweezers can only touch after the first positioning rod 8 passes through the positioning hole 7 . Such a structure ensures that the tip of the tweezers will not be misplaced, and ensures the accuracy of the electrocoagulation tweezers in use.

If the hemostasis site needs to be cleaned, the water storage device can be opened so that the water flows out from the water inlet channel.

As shown in Figure 4 and Figure 5, the electrocoagulation tweezers support includes a base 1-1, the base 1-1 is provided with an opening 1-5, and a wheel 1-2 is arranged inside the base, and the wheel relies on a motor Can rotate along the center of the wheel. A detachable movable seat is arranged on the wheel disk, and a groove 1-3 matching with the two tweezers of the electrocoagulation tweezers is arranged in the movable seat, and sterile flexible substances 1-4 are arranged on the side wall of the groove , through the rotation of the wheel, the grooves located at the opening can be replaced in turn.

After the doctor finishes using the electrocoagulation forceps, he only needs to insert the electrocoagulation forceps into the groove, and pull it out directly when using it again. Since the medical cotton in the groove tightly wraps the tweezers, the tweezers are automatically cleaned when the tweezers come in and out. The roulette rotating at the same time continuously replaces the used grooves, preventing secondary pollution of the tweezers. the

Embodiment 2: Different from Embodiment 1, there is also a suction channel on the tweezers, wherein the suction channel and the water inlet channel are respectively located inside the two tweezers, the entrance of the suction channel is located outside the tip of the tweezers, 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.
