Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to a plasma surgical electrode. Background Technology

[0002] With the continuous development of medical technology, plasma surgical electrodes have been widely used in various soft tissue surgical treatments. The plasma surgical electrode connects to external plasma surgical equipment via its own cable, and its own suction tube connects to external negative pressure suction equipment. However, when different types of plasma surgical electrodes need to be changed during the same surgery, medical staff need to switch and connect the various external devices between different types of plasma surgical electrodes, which is a complicated procedure and increases the operation time. Utility Model Content

[0003] To facilitate operation, this application provides a plasma surgical electrode.

[0004] The plasma surgical electrode provided in this application adopts the following technical solution: include: The handle has an injection port and a suction port at one end. The suction port is detachably connected to an external suction tube, and the injection port is detachably connected to an external injection tube. The electrode assembly is located on the other end of the handle. The electrode assembly has an injection channel and a suction channel. The inlet of the suction channel and the outlet of the injection channel are both located at the same end of the handle and are connected to the outside. The outlet of the suction channel is connected to the suction port, and the inlet of the injection channel is connected to the injection port. Both the injection channel and the suction channel extend along the axis of the handle, with the injection channel surrounding the outer periphery of the suction channel. The suction channel has a first bend in its extending direction, and the injection channel has a second bend in its extending direction. The electrode assembly includes a unclogger for preventing blockage in the suction channel, and the unclogger is slidably disposed within the suction channel.

[0005] In one possible implementation, the unblocking component includes: The unblocking rod is slidably installed in the liquid suction channel, with one end of the unblocking rod extending out of the liquid suction channel and located inside the handle; Barbs are provided on the outer wall of the unclogging rod, and multiple barbs are provided along the axial direction of the unclogging rod.

[0006] In one possible implementation, the barbs extend obliquely from one end to the other along the axial direction of the drain rod.

[0007] In one possible implementation, the electrode assembly further includes a drive member for moving the drain rod, one end of which extends into the handle and is connected to one end of the drain rod to drive the drain rod to slide back and forth axially along the suction channel.

[0008] In one possible implementation, the drive member includes a connecting part that extends into the handle and is slidably connected to the handle. One end of the drain rod is provided with a third bend that protrudes toward the drive member and abuts against the connecting part. The connecting part presses the third bend to drive the drain rod to slide axially back and forth in the liquid suction channel.

[0009] In one possible implementation, the drive unit further includes a pressing part extending out of the handle, one end of which is fixedly connected to the connecting part.

[0010] In one possible implementation, the electrode assembly further includes a first electrode and a second electrode sleeved on the outer wall of the first electrode, a first insulating layer disposed on the inner wall of the first electrode, and a second insulating layer disposed on the inner wall of the second electrode; an injection channel is formed between the second insulating layer and the first electrode, and a suction channel extends through the first insulating layer.

[0011] In one possible implementation, the electrode assembly further includes a third insulating layer disposed on the outer wall of the first electrode and a fourth insulating layer disposed on the outer wall of the second electrode.

[0012] In one possible implementation, the end of the handle away from the electrode assembly is provided with a cable interface for connecting to an external cable, and the cable interface is electrically connected to the first electrode and the second electrode respectively.

[0013] In one possible implementation, the electrode assembly further includes an identification module disposed within the handle, the identification module being electrically connected to the cable interface.

[0014] In summary, this application includes the following beneficial technical effects: When the plasma surgical electrode is in operation, the conductive medium in the injection device enters the injection channel through the external injection pipe, injection interface, and injection channel inlet. The conductive medium is ionized into plasma and output to the injection channel outlet for surgical use. At this time, under the suction action of the suction device, excess liquid and impurities are output to the suction interface through the suction channel inlet and outlet, and then sucked out to the suction device through the external suction pipe. When it is necessary to replace the plasma surgical electrode, there is no need to disconnect the external cable from the surgical device. Simply disconnect the external cable from the cable interface and connect the external cable to the cable interface of another plasma surgical electrode to achieve replacement. The operation is convenient and saves time.

[0015] By pressing the third bend of the connecting part, the unblocking rod slides back and forth axially in the suction channel. The unblocking rod trolley has a certain obstruction effect, which causes the fluid passing through the suction channel to form turbulence inside, automatically flushing the suction channel. This can effectively prevent residual tissue from accumulating on the inner wall of the suction channel, avoid blockage of the suction channel, facilitate the smooth progress of the operation, and thus improve the efficiency of the operation.

The operation is convenient and saves time.

The liquid injection channel 5 is formed between the second insulating layer 12 and the third insulating layer 13, and the liquid absorption channel 6 penetrates through the first insulating layer 11.

[0024] The end of the handle 1 furthest from the electrode assembly 2 is provided with a cable interface 15 for connecting to external cables. The cable interface 15 is electrically connected to the first electrode 9 and the second electrode 10.

The unblocking rod 17 has a certain blocking effect, so that the fluid passing through the suction channel 6 will form turbulence inside it, automatically flushing the suction channel 6. This can effectively prevent residual tissue from accumulating on the inner wall of the suction channel 6, avoid blockage of the suction channel 6, facilitate the smooth progress of the operation, and thus improve the efficiency of the operation.
