[0012] As a preferred solution of the utility model, a dripping pipe is arranged on the handle, and the dripping pipe is connected with the interior of the first straight line segment.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model is energized by an external power supply through a cable connection point, and contacts the bleeding point through the electrocoagulation hole on the hollow metal tube to perform electrocoagulation hemostasis, and adjusts the angle between the first straight line segment and the second straight line segment through the adjustment segment, so that the position of the electrocoagulation hole on the second straight line segment is adjusted, thereby facilitating electrocoagulation hemostasis at a relatively hidden position in nasopharyngeal surgery, improving convenience of use, and improving surgical efficiency and surgical results.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figures 1 to 4 As shown, the utility model provides a disposable adjustable bipolar electrocoagulator with suction for nasal endoscopic surgery, including a handle 1 and a cable connection point arranged on one side of the handle 1, a hollow metal tube 2 with a hollow interior is connected to the handle 1, an electrocoagulation hole 3 is opened on the side of the end of the hollow metal tube 2, and the outer surface of the hollow metal tube 2 is covered with an insulating layer.

[0025] The hollow metal tube 2 includes a first straight segment 201, an adjusting segment 202 and a second straight segment 203. The first straight segment 201 is connected to the handle 1, the adjusting segment 202 is connected to the end of the first straight segment 201, and the second straight segment 203 is connected to one end of the adjusting segment 202. The adjusting segment 202 can be bent arbitrarily and keep the angle fixed. The first straight segment 201, the adjusting segment 202 and the second straight segment 203 are all hollow metal tubes.

[0026] When the utility model is in use, it is powered on by connecting the cable to an external power source, and the insulation of the entire device is ensured by the insulating layer and the handle 1, thereby ensuring the safety of use.

[0027] When in use, according to the position where electrocoagulation hemostasis is to be performed, the angle between the first straight segment 201 and the second straight segment 203 is adjusted by adjusting the segment 202, so that the electrocoagulation hole 3 on the second straight segment 203 can easily reach some relatively hidden positions in nasopharyngeal surgery, thereby improving the convenience of use, and improving the surgical efficiency and surgical effect.

[0028] When electrocoagulation hemostasis is performed, the electrocoagulation hole 3 can make the end of the hollow metal tube 2 form an effect similar to the two ends of bipolar forceps, so that the blood vessel is dehydrated and coagulated to achieve the effect of hemostasis.

[0029] The adjustment section 202 is a metal universal tube.

[0030] The adjustment section 202 of the metal universal tube can ensure the conductivity of the entire hollow metal tube 2 so that it can be bent into any angle and hover through the adjustment section 202, thereby fixing the angle between the first straight section 201 and the second straight section 203, ensuring stability during surgical operations and facilitating hemostasis operations.

[0031] The second straight section 203 includes a hollow tube 204 connected to the adjustment section 202 . The end of the hollow tube 204 is connected to the electrocoagulation tube 205 via threads, and the electrocoagulation hole 3 is arranged on the side of the electrocoagulation tube 205 .

[0032] That is, the second straight line segment 203 includes two parts, and the electrocoagulation tube 205 can be replaced after use, thereby reducing waste of resources.

[0033] The insulating layer is either an insulating sleeve or an insulating coating.

[0034] Ensure safety during use, or adopt other technical means.

[0035] An annular plate 206 is disposed inside the port of the hollow tube 204 . A sealing plate 208 is connected to the inner wall of the hollow tube 204 via a spring sheet 207 . The sealing plate 208 abuts against the annular plate 206 under the elastic force of the spring sheet 207 .

[0036] A water dripping pipe 5 is provided on the handle 1 , and the water dripping pipe 5 is connected with the interior of the first straight line segment 201 .

[0037] Through the elastic force of the spring 207 (the spring 207 is a prior art and will not be described in detail here), the sealing plate 208 is abutted against the annular plate 206 to achieve sealing of the end of the hollow tube 204 and prevent liquid from entering the hollow metal tube 2 through the electrocoagulation hole 3.

[0038] Secondly, when physiological saline is introduced through the drip tube 5, the sealing plate 208 can be pushed open from the inside of the hollow metal tube 2, so that the physiological saline can flow out through the electrocoagulation hole 3 to soak the tissue, so as to intermittently rinse or drip the tissue, so that the tissue can be kept moist, tension-free and the surgical field clean, avoiding excessive temperature from affecting the surrounding important tissues and structures, and reducing the adhesion of eschar and bipolar forceps.

[0039] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
