Description

Technical Field

[0001] The utility model belongs to the field of laparoscopic surgical instruments, and in particular relates to an electric coagulation hook capable of manually controlling the temperature to drop. Background Art

[0002] The laparoscopic electrocoagulation hook is one of the commonly used laparoscopic surgical instruments. It uses electric current to produce a thermal effect on the tissue, thereby achieving the purpose of cutting the tissue. The hemostatic electrode is attached to the bleeding site through the electrocoagulation hook, thereby producing thermal coagulation to achieve the effect of hemostasis.

[0003] The existing laparoscopic electrocoagulation hook has a problem that the temperature of the terminal end is too high after use, which may burn normal intestinal tissues and other tissues during operation, resulting in delayed rupture and the like. Air cooling is often used in the existing technology, but the cooling efficiency is low in the human body cavity. Utility Model Content

DETAILED DESCRIPTION

[0018] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1

[0020] like Figure 1-4 As shown, an electric coagulation hook with manually controlled cooling includes a rod body 1, electric coagulation hooks 5 arranged at both ends of the rod body 1, and an operating part 2. A cooling cavity 501 is arranged in the electric coagulation hook 5, and an outlet is arranged at the end. A water injection pipe 4 connected to the cooling cavity 501 is commonly arranged in the rod body 1 and the operating part 2. The water injection pipe 4 is used to inject physiological saline to cool the electric coagulation hook 5. A manual control button 8 for controlling the opening and closing of the water injection pipe 4 is arranged in the operating part 2.

[0021] A wire portion 3 is provided at the root of the electrocoagulation hook 5, the wire portion 3 passes through the rod body 1 and the operating portion 2, and is provided with a connector 6 for connecting to the host. The wire portion 3 is used to connect the electrocoagulation hook 5 so that the electrocoagulation hook 5 has the ability to cut and stop bleeding.

[0022] The surface of the operating part 2 is provided with a saline connector 7 for connecting to an external saline pumping device. The saline connector 7 is connected to the water injection pipe 4 through a manual button 8. The saline is used to directly cool the electrocoagulation hook 5 from the inside, which has higher cooling efficiency, and the outflowing saline will not damage the organ tissue.

[0023] The manual button 8 includes a button shell 801 arranged in the operating part 2, a slider 802 is arranged inside the button shell 801, and a button cover 803 extending to the outside of the button shell 801 is arranged on the surface of the slider 802, wherein a valve channel 805 is arranged inside the slider 802, one end opening of the valve channel 805 is located on the side wall of the slider 802, which is used to communicate with the saline connector 7, and the other end opening is located on the bottom wall of the slider 802 and is connected to the water injection pipe 4, and the button cover 803 is bounced up by the reset spring 804, and when it is bounced up, the side wall opening of the valve channel 805 is misaligned with the saline connector 7. When in use, since the electrocoagulation hook 5 does not cut only once during cutting, it is necessary to cool the electrocoagulation hook 5 after one cutting, and then move it to another place to continue cutting after cooling. Since the cooling chamber 501 is filled with saline after the first cooling, which affects the secondary heating of the electrocoagulation hook 5, the manual button 8 has a re-absorption function after being closed. Figure 3-4 As shown, when the button cover 803 is released, the slider 802 moves up, so that the valve channel 805 is offset from the saline connector 7, and the slider 802 continues to move up to suck back the saline in the water injection pipe 4. The sucked back amount does not need to be large, and only the drain hole cooling cavity 501 is needed.

[0024] A sealing member 806 is provided on the side wall of the valve passage 805 that contacts the button housing 801 .

[0025] The specific implementation method is as follows: when in use, the electrocoagulation hook 5 is used to cut dirty tissue, and then the button cover 803 is pressed to open the water injection pipe 4, so that saline is injected into the cooling chamber 501 for cooling. After cooling, the position of the electrocoagulation hook 5 is replaced, and the button cover 803 is released to draw a small amount of saline back into the button shell 801, and the saline in the cooling chamber 501 is emptied to prevent affecting heating.

[0026] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
