Device 4 can connect or split, and during connection, the output shaft of motor 2 is passed through in the stomidium of shaft coupling 4 one, and it is general that screw-in shaft coupling 4 is carried
Logical screw, makes both fix axial location.During fractionation, by the rotation of plain screw opposite direction, motor 2 is set to separate with shaft coupling 4.Connection
Axle device 4 is placed between 2 semicircle ring cylinders of the side of cross contiguous block 3.2 identical deep groove ball bearings 5 are embedded in cross
In the circle ring column of contiguous block 3.Bearing positioning table 6 is enclosed within the circle ring column of cross contiguous block 3, during connection, uses interior hexagonal
Fillister head screw is screwed in the screwed hole on the grooving groove face of bearing positioning table 6, makes cross contiguous block 3 and bearing positioning table 6
It is fixed together.During fractionation, by the rotation of hexagon socket cap head screw opposite direction, cross contiguous block 3 is set to take off with bearing positioning table 6
From.Angular contact ball bearing 7 is enclosed within the minor radius circle ring column of bearing positioning table 6.Little back-up ring 8 is attached to the little of bearing positioning table 6
On the bottom surface of radius circle ring column, during connection, screwed in the screwed hole of little back-up ring 8, by little back-up ring 8 with hexagon socket cap head screw
It is fixed on bearing positioning table 6, while fixing the inner ring of angular contact ball bearing 7.It is during fractionation, hexagon socket cap head screw is anti-
Direction rotates, and departs from little back-up ring 8 and bearing positioning table 6.The side of big back-up ring 9 is fitted in the outer ring of angular contact ball bearing 7, set
The large radius circle ring column of cylinder 10 is enclosed within angular contact ball bearing 7, and big back-up ring 9 can be connected with each other or split with sleeve 10, even
When connecing, the screwed hole of big back-up ring 9 is screwed in hexagon socket cap head screw, secured it on sleeve 10.During fractionation, by interior hexagonal
Fillister head screw opposite direction rotates, and departs from both.Rotary connection plate 11 is fixed on sleeve 10 by hexagon socket cap head screw
On, the less column type boss of the radius of rotary connection plate 11 connects shaft coupling 4.
Clamping mechanism can connect or split, and during connection, motor 12 is positioned over the side square indentations of guide track block 13
It is interior, screwed in the screwed hole of guide track block 13 with hexagon socket cap head screw, make both be fixed together.During fractionation, by interior six
Angle fillister head screw opposite direction rotation, departs from both.Guide track block 13 and section bar base plate 14 can be connected with each other or split, even
When connecing, the side of guide track block 13 is close on section bar base plate 14, with hexagon socket cap head screw guide track block 13 is screwed in
In screwed hole, guide track block 13 is set closely to be connected with section bar base plate 14.During fractionation, by the rotation of hexagon socket cap head screw opposite direction
Turn, separate both.Optical axis 15 is supported by guide track block 13, shaft coupling block 17 and grip block 22, and shaft coupling 16 is positioned over leads

Hexagon socket cap head screw opposite direction rotates, and examination push rod 24 departs from slide block 21.
The present invention is operated in the following manner：Fixed mechanism is fixed on into mechanical arm by hexagon socket cap head screw
On, and Transurethral prostatic electroresection A scalpel is placed between grip block 22 and movable grip block 23, will with screw bolt and nut
Grip block 22 and movable grip block 23 are fixed together, meanwhile, the column type stock of push rod 24 is placed in into the annular of scalpel
In spanner.First, the pose for adjusting mechanical arm changes Transurethral prostatic electroresection A scalpel of the present invention clamping connected therewith
The pose of device, and then change the pose of Transurethral prostatic electroresection A scalpel, realize scalpel to patient's lesions position
Positioning.Secondly, the rotary connection plate 11 being attached thereto is driven to rotate by shaft coupling 4 by motor 2, and then, with rotary connection plate
11 connected clamping mechanism rotations, clamping mechanism drives connected Transurethral prostatic electroresection A operating knife device rotation, realizes
The pivoting of scalpel, changes the excision angle of scalpel.Finally, drive what is be attached thereto by shaft coupling 16 by motor 12
Ball-screw 19 rotates, realize with feed screw nut 20 be connected slide block 21 axial movement, and then realize with slide block 21 be connected
The axial movement of push rod 24, by push rod 24 scalpel spanner is promoted, and realizes the axial stretching of scalpel TURP ring.Motor 12 is rotated forward
When, drive push rod 24 to advance, scalpel spanner is promoted, scalpel TURP ring is released, after TURP ring is completely out, motor 12 is reverse
Rotation, drives push rod 24 to retreat, and departs from scalpel spanner, and scalpel TURP ring springs back to original position under self structure, in this time
During bullet, doctor controls the energization pedal of TURP ring by stepping on, and completes once resecting.So repeatedly, until operation is completed.
It is schematic above by reference to the accompanying drawing description of this invention, no restricted, those skilled in the art should
It is understood that in actually implementing, the shape and layout type of each component may occur some changes in the present invention；And at this
Under the enlightenment of invention, other staff can also make make modification and certain structure to similar design of the invention or to the present invention
The equivalent of part.Specifically, without departing from the present invention design aim, it is all it is obvious change with
And the similar Design with equivalent, it is all contained within protection scope of the present invention.
