Description

Technical Field

[0001] The utility model belongs to the technical field of high-frequency electrodes, and particularly relates to a bipolar electrocoagulation forceps with the function of infusion and water control. Background Art

[0002] Electrocoagulation has been used for surgical hemostasis for a long time. The current used for surgery is high-frequency current (about 350KHZ). High-frequency current can safely pass through the human body even if the voltage is as high as several thousand volts, without causing nerve or muscle reactions. The thermal effect of high-frequency current is used to dehydrate and shrink the blood vessel wall, coagulate the blood in the blood vessel, and integrate the blood vessel and the blood clot into one, thereby achieving effective hemostasis. In addition, bipolar electrocoagulation can effectively prevent the undesirable phenomenon of instrument adhesion during coagulation in the presence of liquid such as saline. At present, the clinical use of bipolar forceps basically adopts the method of uninterrupted infusion, which interferes with the vision of medical staff during precision surgery. Bipolar forceps with controllable infusion structure have become the goal of technological innovation in the industry. The water control structures currently used in the industry all expose the water pipe connection on the surface of the forceps body. Due to the imperfect process design, the electrical safety indicators specified by the national standard cannot be met, and the two main components of the water control structure are glued to the surface of the forceps body, which has the risk of falling off during clinical operation. The surface of the tweezers is generally insulated by spraying plastic, but it cannot ensure that the insulation performance 100% passes the national standard testing indicators.

[0019] like Figure 1 As shown, a bipolar electrocoagulation forceps with infusion and water control function includes a metal forceps body 2, an insulating tube, a plastic forceps handle 1, a fixing box 7, a water control device 5, a power cord 8 and an infusion tube 6. The metal forceps body 2 is entirely covered by the plastic forceps handle 1 in the middle and the insulating tubes at both ends, and the tip of the metal forceps body 2 is exposed outside the corresponding insulating tube. The water control device 5 is integrally formed with the plastic forceps handle 1, and the connection between the infusion tube 6 and the metal water pipe on the metal forceps body 2 is implanted inside the plastic forceps handle 1. The fixing box 7 is used to fix the metal forceps body 2, the power cord 8 and the infusion tube 6. The insulating tube includes an insulating tube 3 covering the tip of the metal forceps body 2 and an insulating tube 4 covering the tail of the metal forceps body 2. The tip insulating tube 3 and the tail insulating tube 4 are both made of high temperature resistant insulating tubes. The metal forceps body 2 is formed by high pressure cold extrusion. The plastic forceps handle 1 and the water control device 5 are integrally injection molded. The plastic forceps handle 1 is made of ABS injection molding and riveted to the metal forceps body 2 as a whole. The infusion tube 6 is made of a silicone tube, one end of which is connected to the metal water pipe on the metal tweezers body 2 in the plastic tweezers handle 1 in turn, then passes through the water control device 5, and finally passes through the fixing box 7 to install the water infusion interface. Example 2

[0020] The connection between the infusion tube 6 and the metal water pipe on the metal forceps body 2 is implanted into the plastic forceps handle 1 through the implantation structure 9 .

[0021] The bipolar electrocoagulation forceps of the utility model have the following advantages over traditional products:

[0022] The surface of traditional tweezers is generally made of plastic spraying process, which cannot achieve the hidden danger of 100% passing the power frequency high frequency detection. After the tweezers are formed by high-pressure cold extrusion, the tip and tail of the tweezers are covered with high-temperature resistant insulation tubes. In addition to the high-temperature resistant insulation tubes covering the tip and tail of the tweezers, the middle part of the tweezers handle is made of ABS injection molding and riveted together with the tweezers body. The improved insulator can ensure that the insulation performance 100% passes the national standard requirements.

[0023] In order to solve the potential risk of falling off caused by the conventional process of gluing water control structures, this patent designs the left and right side structures of the water control structure and the plastic parts of the tweezers handle as an integrated injection molding.

[0024] In view of the current industry practice of exposing the water pipe connection device on the surface of the forceps body, which results in the electrical performance of the bipolar forceps failing to meet the indicators specified by the national standard, this patent implants the connection between the water hose and the metal water pipe inside the forceps handle to ensure that the insulation performance of the bipolar forceps 100% passes safety testing.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
