暂无{Abstract}: <B>OBJECTIVE: </B>To quantitatively assess the performance of the new robotic visualization system (Zeiss, KINEVO 900) in terms of visual imaging effect and evaluate its potential application in microscopic vasectomy reversal.<BR><B>METHODS: </B>We made a parallel comparison between the effects of the plane and stereo visual images of KINEVO 900 and optical surgical microscopy (Zeiss, S7), and performed microscopic vasectomy reversal on the rat model using KINEVO 900.<BR><B>RESULTS: </B>Compared with S7, KINEVO 900 provided an even longer working distance (200－625 mm), a 3－4 times larger effective field area and a 1.5－2 times deeper front depth of field with the same working distance of 200 mm. No statistically significant difference was observed in the average anastomosis time and immediate patency rate between the two platforms (P > 0.05).<BR><B>CONCLUSIONS: </B>The 4K3D video image stream outputted by KINEVO 900 is not inferior to that of the optical surgical microscope represented by S7 and is sufficient for microsurgeries in urology and andrology. More prospective randomized clinical animal experiments are needed to further evaluate its application value in andrology.
