The electrotome is a transurethral surgical excision device widely used in the current urinary surgery, and is mainly applied to transurethral prostatectomy (TURP) and transurethral bladder tumor electrotomy (TURBT).
When a clinician performs the two operation modes, the main application mode is to control the electric cutting handle by fingers, linearly move the electric cutting ring for cutting tissues back and forth, and cut and stop bleeding the tissues. The cutting efficiency is low, and the time of one operation is different from half an hour to two or three hours, so that the finger joint is subjected to tens to hundreds of different operation movements. And due to factors such as poor stability, finger joint fatigue, long-time lifting of double arms and the like, uncertainty exists in standardization, safety, excision scope, hemostatic effect and the like of surgical cutting.
The traditional electrotome adopts a 2D hard tube optical lens to generate an image, has no stereoscopic impression, and a doctor cannot accurately judge the shape and structure of the tissue.

As shown in fig. 12, the cut ring assembly 101 includes a cut ring 1011 and a cut ring securing tube 1012. The cut-off ring 1011 is a substantially flexible conductive cable that ensures that the cut-off ring 1011 does not deform and maintains a degree of rigidity when rotating to cut tissue. The electric cutting ring fixing tube 1012 is a hollow tube, and the electric cutting ring 1011 is fixed in a blind hole in the middle of the electric cutting ring fixing tube 1012 to form a rigid body. The cut-off ring assembly 101 is secured to the conductive slip ring 34 through a front flange through hole 10214 below the front flange 1021 of the housing 102. The bottom of the central blind hole of the electric cutting ring fixing tube 1012 is provided with a transverse small hole 10121, after the electric cutting ring 1011 is inserted into the blind hole of the electric cutting ring fixing tube 1012, a wire is welded through the small hole 10121 to be electrically connected with a rotor end (not shown) of the conductive slip ring 34, and a stator end (not shown) of the conductive slip ring 34 is electrically connected with a plasma energy platform through the wire, so that the transfer of plasma energy is realized. After the electric cutting ring 1011 and the electric cutting ring fixing pipe 1012 are installed, glue is used for filling and sealing. In the embodiment of the invention, the electric cutting ring 1011 and the electric cutting ring fixing pipe 1012 are fixedly connected together, and can not be reused and disassembled. In clinical use, the electric cutting ring 1011 with different specifications can be connected with the electric cutting ring fixing tube 1012 in advance according to the requirement, and the electric cutting ring components 101 with different specifications (for example, electric cutting rings with different thicknesses and shapes) are combined and installed on the rotary working component 10 for selection by a clinician. As described above, when the adjustment screw 311 is manually rotated, the conductive slip ring seat 35 moves back and forth with the conductive slip ring 34 and also moves back and forth with the cut-off ring assembly 101.
Two bevel gears 36 are respectively arranged at the output shaft of the motor 37 and the tail end of the electric cutting ring assembly 31, the axes of the bevel gears are crisscrossed, and the motor 37 rotates to drive the electric cutting ring assembly 101 to rotate together, so that the electric rotary cutting function is realized.
The cut ring 1011 is inserted into the cut ring fixing tube 1012 and then sealed by glue. If not sealed, saline may enter the inside of the electrically powered rotary working assembly 10 along the outer circumference of the cut-ring mounting tube 1012, thereby shorting the conductive slip ring and motor.
FIG. 13 is a sectional view of a binocular stereoscopic electric rotary resectoscope according to an embodiment of the present invention. As shown in fig. 13, the speculum seat seal 95 fits within an annular groove of the distal speculum seat 94 of the speculum assembly 9, preventing saline from entering the interior of the electrically powered rotary working assembly 10 along the outer periphery of the electrically powered cutting ring retaining tube 1012.
