staples, as well as other surgical interventions associated with making incisions in deep and narrow cavities.

The purpose of the invention is the dissection of a hollow organ along a circular arc.

The drawing shows a device for electrosurgery.

The device consists of a knife 1, the working part 2 of which is bent at an obtuse angle to the longitudinal axis of the conical contact element 3, and the handle 4. The thickened end 5 of the handle 4 has an end opening leading to the threaded channel 6, into which a screw 7 is screwed connecting knob 4 and turning unit 8, representing cylinder 9, having holes 10 and 11 in the ends, leading to threaded channels 12 and 13. One of them 12 is for fixing screw 14 with locknut 15, the other 13 - to connect the rotary unit 8 with the current-leading wire 16. In addition, in There is also a transverse channel 17 through cylinder 9, through which screw 7 passes, connecting cylinder 9 with a thickened end 5 of handle 4. Screw 7 has a supporting hopper 18 and an annular groove 19 in which the end of screw 14 enters. Swivel 8 by means of wire 16 There is a high-frequency oscillator 20, to which the switching pedal 21 and the passive electrode 22 are connected.

Thanks to the swivel unit 8, it is possible to carry out the free rotation of the knife around its longitudinal axis, and in combination with the flexible wire, the swivel unit allows the knife to freely move in any plane.

The entire surface of the electrode has an electrically insulating coating with the exception of the working part 2 of the knife 1 and the threaded channel 6.

The device is operated as follows.

After securing the patient’s passive electrode 22 and anesthesia, the surgeon, holding the ear funnel in his left ear and the right arm 4 of the electrode connected to the high-frequency generator 20, enters the knife 1 and its element 3 through the ear funnel into the the ear canal and, putting the cutting part of the knife 1 in the right place, makes a transverse arcuate cut of the skin of the upper back and bottom walls, rotating the tool around the longitudinal axis of the element 3 and at the same time moving the knife 1 at different angles to the outer longitudinal axis of the ear canal. In this case, the entire incision is made after connecting the device with the help of a foot pedal 21 to the high-frequency generator 20, or the incision is made without coagulation, and the surgeon turns on the generator 20 only at the moment when bleeding begins at the incision sites.

The use of the proposed device for micro-operations on the ear allows rumor-repairing operations to be performed on a thrasher in a dry field.

Claims (1)

A DEVICE FOR ELECTROSURGERY containing a conical contact element with an electrical insulating coating except for the working part and a connector, characterized in that, in order to dissect the hollow organ along an arc of a circle, the contact element in front of the working part is curved and contains a rotary assembly that allows axial rotation of the contact element, and the connector is mounted on a rotary node and is electrically connected to the contact element. from SU. „1202567
