An embodiment of the invention discloses a transurethral prostate surgical robot resection system comprising a surgical robot device for performing a surgical operation on a predetermined resection range of the prostate of a patient according to a surgical control instruction sent by a surgical control device and sending surgical image information to the surgical control device; a display device for displaying an image to a surgical operator according to display data sent by the surgical control device; the surgical control device for acquiring prostate scan data from an external scanning device and establishing a three-dimensional model of the prostate. A surgical resection path and a surgical resection range are determined according to the three-dimensional model and a preset model to generate the surgical control instruction and send the surgical control instruction to a surgical robot apparatus. The system ensures surgical accuracy and safety by means of the three-dimensional modeling and resection path presetting, improves the resection efficiency, and avoids tissue residue and damage caused by improper human operation and unskilled technology.

The present invention relates to the technical field and particularly to a hepatobiliary surgery operation track tracer. The hepatobiliary surgery operation track tracer comprises an operating table,one side of the operating table is fixedly connected with a support frame, besides, a top end of the support frame is fixedly connected with a connecting rod, besides, one side of the connecting rod is fixedly connected with an arc-shaped sliding rail, a surface of the arc-shaped sliding rail is sleeved with a C-shaped connecting sliding groove, and a bottom part of the C-shaped connecting slidinggroove is fixedly connected with a shadowless lamp. The shadowless lamp can be supported by the arc-shaped sliding rail and the C-shaped connecting sliding groove, a second hinged rod can enable a crown gear to rotate to drive the shadowless lamp to move circumferentially at a bottom part of the arc-shaped sliding rail, ensures that light always faces towards an operation incision, and can adjustpositions and angles of a tracking camera when a shooting field of vision is influenced by operations of a doctor in a shooting process.

The invention discloses a fixed-type self-lighting vaginal speculum for rats, which comprises an upper hinge unit and a lower hinge unit, wherein the upper hinge unit comprises an upper main sheet and an upper dilating sheet, the middle part of the upper main sheet is bent upward to form an arch, and the upper dilating sheet is connected on the highest site of the arch of the upper main sheet and extends forward; the lower hinge unit comprises a lower main sheet and a lower dilating sheet, the middle part of the lower main plate is bent downward to form a recess, lower connecting sheets are arranged on the two sides of the recess and extend up, and the lower connecting sheets are hinged with upper connecting sheets through pin shafts; the arch of the upper hinge unit and the recess of the lower hinge unit are oppositely connected to form a cavity; a positioning sheet is arranged at the rear end of the upper hinge unit and extends downward, and positioning teeth are formed on the positioning sheet and used for clamping the rear edge of the lower hinge unit; a lighting circuit is fixed on the lower side of the front end of the upper dilating sheet and formed by an illuminating lamp, a battery and a power switch; and two binding ropes are connected on the two sides of the lower hinge unit respectively. The vaginal speculum is applied to dilate the vagina of a rat in observation and surgical operation of vagina, cervix and uterine cavity of the rat, is convenient to operate and has high stability.
