Description

Technical Field

[0001] The utility model relates to the technical field of plasma scalpels, in particular to a radiofrequency plasma scalpel with side suction and anti-blocking function. Background Art

[0002] As is well known, tissue debris will be generated during the cutting and ablation process of radiofrequency plasma surgical electrodes. For the radiofrequency plasma surgical electrodes on the market currently (as shown in Figure 1 ), since the suction channels are all arranged below the working electrode, when the tissue debris falls off, it will be immediately sucked into the negative pressure suction channel under the working electrode, without leaving enough time for the plasma vaporization and ablation of the working electrode. Therefore, the volume of the sucked tissue debris is usually relatively large, and it is very easy to get stuck in the electrode base, causing the knife head to be blocked. After the knife head is blocked, on the one hand, the dirty liquid cannot be discharged, affecting the surgical field of view. On the other hand, a large amount of physiological tissue accumulates around the working electrode, seriously reducing the cutting and ablation performance of the knife head, and then affecting the progress of the surgery.

[0003] Therefore, the existing technology has defects and needs to be improved. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a radiofrequency plasma scalpel with side suction and anti-blocking function to solve the problem of blockage of existing radiofrequency plasma surgical electrodes.

[0005] The technical solution of the utility model is as follows: A radiofrequency plasma scalpel with side suction and anti-blocking function is provided, including: a knife head, a handle, an outer suction tube, and a power cord; the knife head includes: an electrode base, a working electrode fixed on the electrode base, an inner suction tube, a knife rod, and a knife rod insulating tube sleeved on the knife rod; the electrode base is provided with a side suction channel, and the side suction channel is arranged on the side of the electrode base; the inner suction tube is directly communicated with the side suction channel on the electrode base, and the knife rod is used to fix the electrode base; the outer suction tube is communicated with the inner suction tube, and the power cord is electrically connected to the working electrode and the knife rod respectively; the knife head, the outer suction tube, and the power cord all penetrate into the handle. Preferably, the inner suction tube is made of an insulating material (such as plastic) or an insulating material layer is attached to the surface of a metal tube.

[0006] A side suction channel is provided on the electrode base, leaving sufficient plasma vaporization and ablation time for the working electrode. As a result, the volume of tissue debris sucked into the side suction channel can be significantly reduced, making it very easy to pass through the side suction channel, thus completely solving the problem of blockage. Moreover, since blockage is avoided, dirty liquid can be quickly discharged, preventing it from affecting the surgical field of view. Further, since the cut physiological tissue does not accumulate around the working electrode, the cutting and ablation performance of the tool tip is ensured, effectively guaranteeing the stable progress of the operation.

[0007] Preferably, a front suction channel can also be provided at the front end of the electrode base, and the front suction channel is communicated with the inner suction tube. The cross-sectional area of the front suction channel is smaller than that of the side suction channel. This solution can both avoid blockage and retain the suction function at the front end of the tool tip.

[0008] Further, the side suction anti-blocking radiofrequency plasma scalpel further includes: a flushing tube. The tool bar is provided with a water outlet hole, and the water outlet hole is communicated with the flushing tube. The flushing tube penetrates into the handle. Further, the electrode base is provided with a guiding arc surface. The water outlet hole and the guiding arc surface are arranged on the same side. The guiding arc surface is used to guide physiological saline to the working electrode to form a loop, enabling the plasma to be generated continuously and stably.

[0009] Further, the electrode base is provided with a guiding boss, and the suction port of the side suction channel is arranged on the guiding boss. A guiding boss is arranged around the suction port of the side suction channel, and the guiding boss can provide guiding and positioning functions.

[0010] Further, there is at least one water outlet hole. In a preferred solution, there are 3 water outlet holes arranged in a triangular pattern. Multiple water outlet holes can ensure the stability of the flowing physiological saline.

[0011] Adopting the above solution, the present utility model provides a side suction anti-blocking radiofrequency plasma scalpel. By providing a side suction channel on the electrode base, sufficient plasma vaporization and ablation time is reserved for the working electrode. As a result, the volume of tissue debris sucked into the side suction channel can be significantly reduced, making it very easy to pass through the side suction channel, thus completely solving the problem of blockage. Moreover, since blockage is avoided, dirty liquid can be quickly discharged, preventing it from affecting the surgical field of view. Further, since the cut physiological tissue does not accumulate around the working electrode, the cutting and ablation performance of the tool tip is ensured, effectively guaranteeing the stable progress of the operation.
