[0039] The specific embodiments of the present application will be described below in conjunction with the accompanying drawings and examples:

[0040] It should be noted that the structures, proportions, sizes, etc. shown in the drawings of the present specification are only used to cooperate with the content disclosed in the specification, so that those skilled in the art can understand and read, and are not used to limit the implementation conditions of the present application. Any modification of structure, change of proportion relationship or adjustment of size, which does not affect the effect and purpose that can be achieved by the present application, should still fall within the scope of the technical content disclosed by the present application.

[0041] At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" referred to in the present specification are only for the convenience of clear description, and are not used to limit the scope of the present application. The change or adjustment of the relative relationship without substantial change of technical content is also regarded as the implementation scope of the present application.

[0042] Example 1, in conjunction with Figures 1 to 3As shown, the embodiment provides an electrode assembly, which comprises a support body, an electrode body 1 movably arranged on the support body, and a plurality of needle-shaped electrode needles 2 arranged on the electrode body 1. The electrode body 1 is movable relative to the central axis of the support body. The plurality of electrode needles 2 have the same length and are insulated from each other. The electrode needles 2 are in direct contact with the human tissue, so that the current is transmitted to the human tissue through the support body, the electrode body 1, and the electrode needles 2.

[0043] For example, in combination with Figure 3 As shown, the electrode body 1 is in a rectangular structure, and the electrode needles 2 are arranged on the contact surface of the electrode body 1. The needle heads of the electrode needles 2 extend in the opposite direction of the contact surface. The needle heads of the electrode needles 2 are in direct contact with the human tissue, serving as a conductive medium for the generated high-frequency current to be introduced into the human tissue area to be treated. Through the thermal effect of the current, the blood in the blood vessels is coagulated, thereby achieving the purpose of hemostasis.

[0044] Specifically, the spacing between the plurality of electrode needles 2 is the same. The same spacing can uniformly arrange the electrode needles 2 on the electrode body 1, and can ensure that the energy can be more uniformly applied to the target tissue when a larger area or a longer incision is treated, thereby avoiding excessive damage to the local area due to excessive concentration of energy, and thereby helping to achieve more uniform current distribution. The number of electrode needles 2 can be selected according to actual application.

[0045] Specifically, the spacing between adjacent electrode needles 2 is 2-5 mm. Preferably, the spacing between adjacent electrode needles 2 is 2.5 mm, which can ensure that there is enough space for the current to pass through the electrode needles 2 to effectively act on the target tissue, and also not too large to affect the synergistic effect of the adjacent area, so that medical personnel can more accurately control the electrocoagulation process and reduce the impact on the surrounding healthy tissue.

[0046] Specifically, in combination with Figure 2 As shown, in order to make the electrode body 1 displace around the central axis of the support body, a ball 31 is arranged on the electrode body 1. The support body is provided with a ball socket 51 corresponding to the ball 31. The ball 31 is movably arranged in the ball socket 51, so that the electrode body 1 drives the electrode needles 2 to rotate around the central axis of the support body. The support body and the electrode body 1 are both made of metal material, which can be selected from copper, gold, aluminum, etc. for conducting current. The ball joint connection of the support body and the electrode body 1 can make the electrode body 1 rotate in multiple directions, so that the electrode body 1 connected with the ball 31 can drive the electrode needles 2 to rotate around the center of the ball 31 in all directions, thereby realizing the angle adjustment of the electrode needles 2, and improving the flexibility of the electrode assembly.

[0047] Exemplarily, the support body is in a cylindrical shape, and the support body is provided with an insulating member which is axially sleeved on the support body. The support body comprises an electrically conductive rod 3 connected with the electrode body 1, and a handle 5 movably connected with the electrically conductive rod 3, a spherical cavity 51 is formed on the handle 5, and a spherical body 31 is arranged on the electrically conductive rod 3 corresponding to the spherical cavity 51, so that the bottom end of the electrically conductive rod 3 can be displaced around the central axis of the handle 5, thereby realizing the omnidirectional rotation of the electrode needle 2 around the spherical center of the spherical body 31, and further realizing the angle adjustment of the electrode needle 2, which is suitable for the electrocoagulation hemostasis operation requiring multiple angle adjustments.

[0048] In the embodiment, the electrically conductive rod 3 and the outer wall of the handle 5 are sleeved with an insulating member, and the insulating member is made of an insulating protective material, such as polyvinyl chloride (PVC). During the electrocoagulation operation, the handle 5 in the power-on state can generate heat at the position in contact with the electrically conductive rod 3, and the insulating protective material arranged on the electrically conductive rod 3 and the handle 5 can play an electrically insulating role, thereby avoiding the current shunting caused by the contact between the power-on support body and other parts during the operation, and affecting the efficiency of wound treatment.

The high-frequency signal generator is responsible for generating high-frequency current, using radio frequency (RF) technology, with a frequency range generally between 300 kHz and 1 MHz, which helps to reduce damage to surrounding tissues while achieving effective coagulation effect. The control circuit board includes components such as microprocessors or single-chip microcomputers, which are used to control and regulate output power, working mode, and respond to user input (such as footswitch). The power amplifier is used to enhance the signal strength generated by the high-frequency signal generator, so as to be able to provide enough energy to the electrode needle 2 for coagulation operation. The feedback system is used to monitor output parameters (such as current, voltage, power, etc.) in real time, and the protection circuit is designed with various protection mechanisms, such as overload protection, short circuit protection, temperature protection, etc., to ensure the safety of the operator and the reliability of the device itself. The connection interface is used to connect the support body, the negative electrode, the footswitch and other external devices, to ensure the safety and efficiency of signal and power transmission. The insulating sleeve 6 connected between the connection interface and the support body is provided with an insulating protective material, which is also an insulating protective material as the above-mentioned insulating member, and plays an electrically insulating and protective role on the cable.

[0051] Exemplarily, the pipe end of the insulating sleeve 6 is provided with an elastic clamping joint 61, and the handle 5 is correspondingly provided with a plug-in interface 52. The elastic clamping joint 61 and the plug-in interface 52 are clamped and matched to realize the connection of the insulating sleeve 6 and the handle 5. The connection part of the elastic clamping joint 61 and the handle 5 is selected from a metal material, so that the cable in the insulating sleeve 6 conducts current to the handle 5.

For multiple connected hemostasis plates 41, the fixing belt 45 of the hemostasis plate 41 can be detached, the multiple hemostasis plates 41 are connected by the connecting structure, and the hemostasis plates 41 located at the four corners are fixed by the fixing belt 45 with a proper length, so that the compression hemostasis function of a large area wound surface is realized.

[0054] In this embodiment, as shown in Figure 4 For a large area wound, multiple hemostasis plates 41 need to be connected to ensure complete coverage of the wound surface, and adjacent compression hemostasis members 4 are connected by the connecting structure and can rotate relative to each other.

[0055] Specifically, as shown in Figure 5 、 Figure 6 The connecting structure is detachably arranged on the compression hemostasis member 4, and the compression hemostasis member 4 and the connecting structure can be separated for disinfection after use, so as to ensure the safety of use. The compression hemostasis member 4 is provided with a clamping groove 47 at each of the four corners, and the connecting structure comprises an elastic buckle 461, which is elastically clamped by the elastic buckle 461 and the clamping groove 47 to realize the connection between the connecting structure and the compression hemostasis member 4. The shape of the elastic buckle 461 and the clamping groove 47 is matched, a notch is formed in the elastic buckle 461, the elastic buckle 461 is inserted into the clamping groove 47, and the elastic buckle 461 is abutted against the inner wall of the clamping groove 47, so that the notch gradually shrinks, and when the elastic buckle 461 is inserted into the groove bottom of the clamping groove 47, the elastic buckle 461 restores the elasticity and is abutted against the inner wall of the clamping groove 47.

[0056] In this embodiment, as shown in Figure 7 The clamping groove 47 is provided with a pressure spring 467 corresponding to the position of the notch, and the pressure spring 467 can more stably abut the elastic buckle 461 against the inner wall of the clamping groove 47 by using its own elasticity.
