Switch 27 is and circuit board electrical connection, the wire connection terminal of pull rod back seat connect the conducting wire 48 of a setting plug 49, and plug 49 is inserted
Enter in socket, pull rod back seat, fixture block 11, taper apical axis 14, pull rod, drive link 2, tool tip 42, the first cutter head 41 and the second knife
First 40, which sequentially form access, generates electric current, and the first cutter head 41 and the second cutter head 40 are electrode knife head, which becomes hand
Art electrode, wherein the first cutter head 41 is used for blood coagulation, the second cutter head 40 is used to cut with cutter tooth 43.When needing cutting, press and cut
Switch, cutter head electrode are closed, and host output cutting power reaches cutting function；When needing blood coagulation, host output blood coagulation power,
Reach coagulation function.
First cutter head 41 is driven by pull rod, and pull rod is driven by spanner 25, during work, is pulled back spanner 25, is made oscillating rod
Around the centre of sphere of the top semicircle sphere 16 of oscillating rod 23, arc swing, spherical chamber are moved with oscillating rod 23 backward for 23 bottom end
While drive the also swing backward of sphere 17, pull rod back seat is made also to move backward, targeting part 19 is between two lower limiting boards 18
It moves backward, pull rod back seat drives pull rod to move backward by fixture block 11, and pull rod is pulled by drive link 2 on the first cutter head 41 again
Rear articulated shaft 45 move backward, the first cutter head 41 is rotated around preceding articulated shaft 44, opposite second cutter head 40 of the first cutter head 41 to
Outer opening, the first cutter head 41 and the second cutter head 40 are in the forward acute angle shape setting of angle mouth；When unclamping spanner 25, spanner 25
It is resetted forward under the action of resetting spring 22, then pull rod back seat drives pull rod and drive link 2 to push forward by fixture block 11
Articulated shaft 45 afterwards, the first cutter head 41 are turned round around preceding articulated shaft 44, and 41 opposite second cutter head 40 of the first cutter head is closed, the first cutter head
41 are located at 40 side of the second cutter head and disappear with the angle of the second cutter head 40.
The runner 9 can be by rotating manually, and runner 9 overcomes the resistance of positioning ball 36, in 9 rotation process of runner,
Positioning ball 36 is crushed in locating groove 34, stirs runner 9 when going to precalculated position human hand stopping, positioning ball 36 is positioning
It is stretched under the elastic force of spring 37 in corresponding locating groove 34, runner 9 and connecting shaft 30 is prevented to rotate.
Runner 9 rotate during, connecting shaft 30 is rotated with runner 9, due to connecting shaft 30 with simultaneously cap 5 be threadedly coupled,
Connecting shaft 30 drives and cap 5 rotates, and cap 5 drives outer pipe flange 56 and outer tube 4 to rotate therewith, since tool tip 42 is installed in
4 front end of outer tube, so tool tip 42 is rotated with outer tube 4, tool tip 42 drives drive link 2 and pull rod to rotate again, interior bar 3 and
Taper apical axis 14 rotates, the rotation of positioning groove on taper apical axis 14, and fixture block 11 always in partial insertion positioning groove not
Movement, is evacuated lantern ring 29 and pull rod back seat does not also rotate.
The rotation final purpose of runner 9 is in order to which the first cutter head 41 and the second cutter head 40 is made to prolong before and after connecting shaft 30
The center axis thereof stretched, when the first cutter head 41 is located at the positive upside of the second cutter head 40, the rear interval of articulated shaft 45 is set on preceding hinge
The back lower place of spindle 44.
The pumping lantern ring 29 is preceding aspirating hole 46,4 tube chamber of outer tube, connection on the tube wall of outer tube 4 in order to siphon away flue gas
Centre bore 6, the rear aspirating hole 7 in connecting shaft 30, the pumping slot 28 for being evacuated lantern ring 29 and the exhaust tube 8 of axis 30 are sequentially communicated, can
The flue gas generated in surgical procedure is made to enter from preceding aspirating hole 46, and is finally taken away from exhaust tube 8.
