[0045] The present utility model provides a plasma surgical device capable of injecting an antifoaming liquid.

[0046] Please refer to Figure 1 , Figure 1 which is a partial structural schematic diagram of an embodiment of the plasma surgical device capable of injecting an antifoaming liquid provided by the present utility model. Figure 1 .

[0047] In an embodiment of the present utility model, the plasma surgical device capable of injecting an antifoaming liquid includes:

[0048] A tool assembly 100, provided with a liquid outlet and a liquid injection channel communicating with the liquid outlet;

[0049] A first liquid injection assembly 200 communicating with the liquid injection channel, for injecting a conductive solution into the liquid injection channel so that the conductive solution flows through the surgical site through the liquid outlet; and

[0050] A second liquid injection assembly 300 communicating with the liquid injection channel, for injecting an antifoaming liquid into the liquid injection channel so that the antifoaming liquid flows through the surgical site through the liquid outlet to eliminate the bubbles generated by the ionization of the conductive solution.

[0051] The plasma surgical device capable of injecting defoaming liquid in the technical solution of the present utility model includes a tool assembly 100, a first liquid injection assembly 200, and a second liquid injection assembly 300. The first liquid injection assembly 200 injects a conductive solution into the liquid injection channel. After the conductive solution flows from the liquid outlet to the surgical site, the electrode on the tool assembly 100 discharges to ionize the conductive solution to generate plasma. Through the covalent bond action between the plasma and cell molecules, the functions of vaporizing and coagulating soft tissues at the surgical site are achieved. During the process of ionizing the conductive solution to generate plasma, bubbles will be generated. The second liquid injection assembly 300 injects defoaming liquid into the liquid injection channel, and the defoaming liquid flows through the surgical site from the liquid outlet, which can eliminate the bubbles generated by the ionization of the conductive solution, thereby reducing the blockage of the surgical site by the bubbles, providing a clear surgical field of view, and further reducing the operation difficulty of the surgery and improving the safety of the surgery.

[0052] Among them, the specific ratio of the conductive solution and the defoaming liquid can be adjusted as needed, as long as the defoaming liquid does not affect the conductivity of the conductive solution, and no limitation is made here.

[0053] In an embodiment, the plasma surgical device further includes a mixing assembly 400. The mixing assembly 400 is provided with a mixing chamber 4111. One end of the mixing chamber 4111 is communicated with the liquid injection channel, and the other end of the mixing chamber 4111 is communicated with the first liquid injection assembly 200 and the second liquid injection assembly 300, so that the conductive solution and the defoaming liquid are mixed in the mixing chamber 4111.

[0054] Referring to Figure 2 , in the embodiment of the present utility model, the plasma surgical device further includes a mixing assembly 400. The first liquid injection assembly 200 injects the conductive solution into the mixing chamber 4111 of the mixing assembly 400, and the second liquid injection assembly 300 injects the defoaming liquid into the mixing chamber 4111 of the mixing assembly 400, so that the conductive solution and the defoaming liquid are mixed inside the mixing chamber 4111, making the conductive solution and the defoaming liquid evenly mixed. There is defoaming liquid around the conductive medium in the conductive solution. When bubbles are generated by the ionization of the conductive solution, the defoaming liquid around the conductive medium can quickly eliminate the bubbles, improving the defoaming efficiency and shortening the defoaming time, further improving the operability and safety of the surgery; on the other hand, the evenly mixed conductive solution and defoaming liquid can ensure that the conductivity of the mixed solution released to the surgical site meets the ionization requirements, avoiding affecting the ionization function of the plasma surgical device. The mixing assembly 400 can be a stirrer, and the conductive solution and the defoaming liquid are evenly mixed by a rotating stirring member; the mixing assembly 400 can also be a static mixer, which uses the mixing unit fixed in the pipe to change the flow state of the conductive solution and the defoaming liquid in the pipe to achieve the purpose of well dispersing and fully mixing the conductive solution and the defoaming liquid.

[0055] In an embodiment, the mixing assembly 400 includes:

[0056] A housing 410 is provided with a mixing chamber 4111; and

[0057] A mixing member 420 is fixed within the mixing chamber 4111. The mixing chamber 4111 is divided by the mixing member 420 into at least two diversion channels. The conductive solution and the defoaming liquid are mixed at one end of the mixing member 420 away from the liquid injection channel to form a mixed solution. The mixed solution is diverted through the at least two diversion channels and remixed at one end of the mixing member 420 close to the liquid injection channel.

[0058] Referring Figure 3 , in an embodiment of the present invention, the mixing assembly 400 includes a housing 410 and a mixing member 420. The conductive solution and the defoaming liquid are mixed into a mixed solution at one end of the mixing member 420 away from the liquid injection channel. When the mixed solution passes through a plurality of diversion channels provided in the mixing member 420, it is divided into multiple fluid streams. After passing through the mixing member 420, the multiple fluid streams are remixed at one end of the mixing member 420 close to the liquid injection channel, thereby improving the uniformity of the mixing of the conductive solution and the defoaming liquid, further enhancing the defoaming effect of the defoaming liquid, and reducing the influence of the defoaming liquid on the conductivity of the conductive solution.

[0059] In one embodiment, the mixing assembly 400 includes a plurality of mixing members 420 connected end to end. The mixed solution sequentially passes through the plurality of mixing members 420 and enters the liquid injection channel; and / or,

[0060] The mixing member 420 has at least one spiral blade. Each spiral blade has two opposite side walls 421. Each side wall 421 and the inner wall of the mixing chamber 4111 enclose a diversion channel.

[0061] Combining Figure 3 and Figure 4 , in an embodiment of the present invention, the mixing assembly 400 includes a plurality of mixing members 420 connected end to end. After the mixed solution sequentially passes through the plurality of mixing members 420, it can be mixed more uniformly, improving the mixing effect and ensuring the conductive performance and defoaming function of the mixed solution. On the other hand, the structure of the plurality of mixing members 420 connected end to end is relatively simple, easy to implement, and easy to disassemble and clean, facilitating maintenance and replacement.

[0062] Combining Figure 3 and Figure 4, in an embodiment of the present utility model, the mixing member 420 has at least one spiral blade. Two side walls 421 of the spiral blade and the inner wall of the mixing chamber 4111 form two flow dividing channels. The mixed solution formed by the conductive solution and the defoaming liquid is divided into two streams when passing through the mixing member 420, and then is mixed again at one end of the mixing member 420 close to the liquid injection channel. The structure of the mixing member 420 is simple and occupies a small volume. The side wall 421 of the spiral blade has a small blockage to the mixed solution, which not only ensures that the mixed solution can flow smoothly through the mixing member 420, but also causes the mixed solution to collide with the side wall 421 during the process of passing through the flow dividing channel to generate turbulence, improving the mixing effect. Specifically in this embodiment, the mixing assembly 400 includes a plurality of spiral mixing members 420, and the connection parts of two adjacent spiral mixing members 420 are arranged in a cross shape. For example, when two mixing members 420 are provided, the mixed solution is divided into solution A and solution B when passing through the first mixing member 420. When entering the second mixing member 420, solution A is divided into solution A1 and solution A2, and solution B is divided into solution B1 and solution B2. Among them, solution A1 and solution B1 enter the same flow dividing channel of the second mixing member 420 for mixing, and solution A2 and solution B2 enter another flow dividing channel of the second mixing member 420 for mixing, further improving the mixing effect, ensuring that the conductive solution and the defoaming liquid are mixed evenly, thereby improving the defoaming effect of the defoaming liquid and reducing the influence of the defoaming liquid on the conductivity of the conductive solution.

[0066] Wherein, the sealing cover 412 is provided with a first joint 4121 and a second joint 4122 communicating with the mixing chamber 4111. The first joint 4121 communicates with the first liquid injection assembly 200, and the second joint 4122 communicates with the second liquid injection assembly 300; one end of the mixing tube 411 away from the sealing cover 412 is provided with a third joint 4113 communicating with the mixing chamber 4111, and the third joint 4113 communicates with the liquid injection channel.

[0067] Refer to Figure 3In the embodiment of the utility model, the housing 410 includes a mixing tube 411 and a sealing cover 412. A mounting port 4112 is provided at one end of the mixing tube 411. The flow mixing element 420 is installed into the mixing chamber 4111 through the mounting port 4112, and the mounting port 4112 is then sealed by the sealing cover 412, so that the flow mixing element 420 can be easily assembled into the mixing chamber 4111, thereby reducing the manufacturing and assembly difficulties of the mixing assembly 400. Specifically in this embodiment, a sleeve tube is provided on the sealing cover 412, and the end of the mixing tube 411 provided with the mounting port 4112 has a larger diameter and is sleeved on the outside of the sleeve tube. A sealed connection is achieved by gluing or interference fit, thereby enhancing the connection strength between the mixing tube 411 and the sealing cover 412, improving the sealing effect, and reducing the possibility of leakage. The sealing cover 412 is also provided with a first joint 4121 and a second joint 4122, which are convenient for connecting the first injection assembly 200 and the second injection assembly 300 respectively through pipelines.

[0076] In one embodiment, the defoaming liquid is simethicone or dimethicone.

[0077] In the embodiment of the present utility model, the defoaming liquid is dimethicone or simethicone. Simethicone is a mixture of liquid dimethicone.

The liquid inlet and the liquid outlet are arranged adjacent to each other. The liquid outlet releases the conductive solution and the defoaming liquid. Only a part of the conductive solution is ionized by the electrode of the tool assembly 100. Therefore, the liquid suction assembly 600 can suck the remaining liquid away from the surgical site through the liquid inlet, avoiding the accumulation of liquid at the surgical site. And during the process of sucking the liquid, it can also suck part of the bubbles, thereby further reducing the visual field obstruction at the surgical site, facilitating the user's surgical operation, and improving the safety of the operation.
