Embodiment 1

[0030] like Figure 1 to Figure 4 As shown, a plasma surgical instrument mainly includes an electrode assembly and an insulating sleeve 1. One end of the insulating sleeve 1 is closed and one end is open and used to be worn on the finger. That is, the insulating sleeve 1 constitutes a finger sleeve structure. The electrode assembly includes a working pole 2, a return pole 3 and a cable 4. The working pole 2 and the return pole 3 are arranged at the closed end of the insulating sleeve 1 and separated by electrical insulation. The cable 4 is separated along the insulation The sleeve 1 is routed and electrically connected to the working pole 2 and the return pole 3 respectively. The working pole 2 and the return pole 3 are connected to the external plasma surgery host through the cable 4. The switch is controlled on the foot pedal. During the operation, the insulation is The sleeve 1 is put on the finger, the working pole and the return pole form a bipolar electrode structure, th...

Embodiment 2

[0036] When the insulating sleeve 1 is worn on the fingers, the condition of loosening and slipping may occur, which will affect the accuracy of the surgical operation. In order to ensure the wearing stability of the plasma surgical instrument, the insulating sleeve 1 is also provided with useful A fixing device for fixing the insulating sleeve 1 on the finger.

[0037] Specifically, as Figure 5 As shown, the fixing device is a plug body layer 8 arranged on the inner wall of the insulating sleeve 1, and the plug body layer 8 can have elasticity, so as to fill the gap between the plugging insulating sleeve 1 and the fingers, so that the insulating sleeve can be tightened. The function of fixing the cylinder 1 on the finger, and the plug body layer 8 preferably adopts insulating material to improve the insulation protection and improve the safety in use. The side of the plug body layer 8 facing the finger can also have several protrusions to increase frictional resistance, Imp...

Embodiment 3

[0042] like Figure 8 As shown, the difference from the first embodiment is that the insulating sleeve 1 is a plastic part that is easy to bend and deform. The insulating sleeve 1 can be made of one of PVC, PC, PTFE, and silicone materials. The barrel can be bent as a whole, so as to adapt to the movement of the fingers and ensure the flexibility of the surgical operation.

Abstract

The plasma surgical instrument comprises an electrode assembly and an insulating sleeve, one end of the insulating sleeve is closed, the other end of the insulating sleeve is open, the insulating sleeve is used for being worn on a finger, the electrode assembly comprises a working electrode, a loop electrode and a cable, and the working electrode and the loop electrode are arranged at the closed end of the insulating sleeve and are electrically insulated from each other; and the cable is electrically connected with the working electrode and the loop electrode respectively. The plasma surgical instrument is directly worn on a finger, the finger of a surgical operator can perform surgical operation close to superficial tissue, operation is more flexible and accurate, ablation and blood coagulation operation is more stable and reliable, damage to non-target tissue is avoided, surgical wounds are effectively controlled, surgical accuracy is improved, and the surgical effect is improved.

Description

technical field [0001] The invention relates to the technical field of medical surgical instruments, in particular to a plasma surgical instrument. Background technique [0002] The plasma scalpel uses the energy generated by the plasma generator to form a highly concentrated plasma thin layer between the plasma cutter head and the tissue. The plasma in the thin layer is accelerated by the electric field and has enough energy to smash the organic matter in the tissue. Molecular chains decompose the tissue into simple molecules, atoms or low molecular weight gases, so as to achieve the function of ablation and cutting. Since the current does not flow directly through the tissue, the tissue heats very little, so the treatment temperature is low (40-70°C), and it can maintain The activity of the cells reduces the thermal damage of the tissue, thereby achieving a minimally invasive effect. [0003] The traditional plasma scalpel is usually in the shape of a slender rod, which r...
