TECHNICAL FIELD
[0001] The present application relates to the technical field of medical devices, in particular to a bipolar electrocoagulation device with water and electricity cooperation. BACKGROUND
[0002] The bipolar electrocoagulation device is a medical device that uses the heat effect of high-frequency current to make protein tissue denature and coagulate, and the blood vessel wall shrinks and dehydrates, and the blood vessel and blood clots are integrated to achieve effective hemostasis. When the bipolar electrocoagulation device is applied, the energy is only concentrated between the two electrodes of the bipolar electrocoagulation device, the required electricity is significantly reduced compared with the monopolar device, and the heat diffusion and damage to the adjacent tissue are also reduced.
[0003] The ordinary bipolar electrocoagulation device mainly includes a clamp head, a clamp rod, an operating handle, a high-frequency cable and the like, and the clamp head is controlled to be closed through the operating handle. In endoscopic surgery, due to the limitation of the endoscope, the operation space of the ordinary bipolar electrocoagulation device is small, and it is difficult to reach the expected tissue position and perform electrocoagulation hemostasis. At the same time, the existing bipolar electrocoagulation device still has some drawbacks in the process of electrocoagulation hemostasis, for example: 1. The scab and adhesion on the surface of the tissue during the coagulation process lead to a decrease in coagulation effect; 2. The tissue damage is too high, causing tissue or blood vessel carbonization and damage; 3. The tissue is adhered to the clamp sheet after electrocoagulation, and the tissue is easily injured or the electrocoagulation or blood vessel closure is ineffective during the withdrawal of the surgical device. Although some doctors use physiological saline to cool and prevent adhesion in open surgery, it is very inconvenient to operate, and the physiological saline is continuously turned on during the entire surgical process, and water continuously drips from the end of the device, which not only affects the operation but also increases the safety risk of the operation.

[0056] The present application will be described in detail below by referring to the accompanying drawings and combining with the embodiments.
[0057] As shown in Figures 1 to 8 The present embodiment provides a bipolar electrocoagulation instrument with water and electricity cooperation, which comprises a handle part 1, a shaft part 3 and a jaw part 2, the jaw part 2 is arranged at the end of the shaft part 3 away from the handle part 1, wherein:
[0058] The handle part 1 is provided with a pulling driving assembly 4 for controlling the opening and closing state of the jaw part 2 and a water and electricity joint control assembly 5 for controlling the water and electricity on-off of the jaw part 2;
[0059] The water circuit and the electric circuit of the jaw part 2 are in the state of being simultaneously opened or simultaneously disconnected through the water and electricity joint control assembly 5;
[0060] When the jaw part 2 is in the opened state, the water and electricity joint control assembly 5 is limited by the pulling driving assembly 4 so that the water circuit and the electric circuit of the jaw part 2 are in the state of being normally disconnected.
[0061] The present embodiment can make the person with fast speed realize the state of the water circuit and the electric circuit of the jaw part 2 being simultaneously opened or simultaneously disconnected through a single action by arranging the water and electricity joint control assembly 5 in the handle part 1, realize the technical ingenuity of electrocoagulation and water dripping at the same time, no electrocoagulation and no water dripping, thereby effectively solving the problem of poor water and electricity coordination of the existing bipolar electrocoagulation instrument.
[0062] In addition, when the jaw part 2 is in the open state, the pulling driving assembly 4 can restrict the water and electricity control assembly 5, so as to avoid the water and electricity control assembly 5 from triggering the water circuit and the electricity circuit of the jaw part 2 to change from the disconnected state to the open state, thereby playing an insurance role when the jaw part 2 is in the open state, avoiding the water and electricity circuit of the jaw part 2 from being connected, reducing the risk of misoperation of the operator, avoiding the non-diseased tissue from being electrocoagulated, and increasing the safety of the operation.
[0063] In the embodiment, the water and electricity control assembly 5 comprises a control button 51, a rotary transmission structure 52, a reset spring 53, an electricity circuit control board 54, and a water circuit control rod 55.
[0064] The rotary transmission structure 52 is rotationally connected in the handle part 1, and is divided into a power input section and a power output section by a rotation axis of the rotary transmission structure 52. The control button 51 is arranged on the handle part 1 and faces the power input section of the transmission structure. One end of the reset spring 53 is connected in the handle part 1, and the other end is connected to the power output section of the rotary transmission structure 52. The control switch of the electricity circuit control board 54 and the power input end of the water circuit control rod 55 are arranged towards the power output section of the rotary transmission structure 52.
[0065] After the pulling driving assembly 4 drives the jaw part 2 to be in the closed state, the restriction of the pulling driving assembly 4 to the water and electricity control assembly 5 is released. At this time, the control button 51 is pressed to drive the rotary transmission structure 52 to rotate in the handle part 1. After the rotary transmission structure 52 rotates, the control switch on the electricity circuit control board 54 is pressed, so that the electricity circuit is opened, and at the same time, the water circuit control rod 55 is no longer pressed by the rotary transmission structure 52, so that the water circuit is connected. After the water circuit is connected, the physiological saline enters the jaw part 2 through the water circuit, so that the electricity circuit is conducted, the electricity circuit between the fixed jaw plate 21 and the movable jaw plate 22 of the jaw part 2 is conducted, and the electrocoagulation operation is completed. In the embodiment, the conductivity of the physiological saline is also utilized to control the on-off of the circuit, so that when the physiological saline is not in place during the initial electrocoagulation, the circuit cannot be conducted physically, and the possibility of the circuit being conducted without the water circuit being connected is eliminated, thereby providing reliable safety protection for the operation of the operator. After the control button 51 of the water and electricity control assembly 5 is released, the rotary transmission structure 52 is reset under the action of the reset spring 53. At this time, the control switch of the electricity circuit control board 54 is no longer pressed, and after the water circuit control rod 55 is pressed, the water circuit control rod 55 disconnects the water circuit. Due to the control switch, even if there is conductive physiological saline in the water circuit, the circuit can also be prevented from being conducted.
