Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is a bipolar sectional structure sketch map of singly opening elastic separating plier of the present utility model;
Fig. 2 is the enlarged diagram of A among Fig. 1;
Fig. 3 is the enlarged diagram of B among Fig. 1.
The specific embodiment
Fig. 1～Fig. 3 comprises claw beam 3, pull bar 2, handle, caliper and wheel set assembly 4 in conjunction with having provided a kind of bipolar elastic separating plier of singly opening.The outer surface of claw beam 3 is provided with insulation sleeve 31.
Caliper is decided to realize being rotatedly connected by dielectric pin 13 between binding clip 11 and the moving binding clip 12 by deciding binding clip 11 and moving binding clip 12 is formed.Handle is made up of the preceding pincers of insulation handle 71 and insulation forceps major handle 72, and the preceding pincers of insulation handle 71 and insulation forceps major handle 72 are realized being rotatedly connected by pin 73.Before insulation, be provided with wheel set assembly 4 on the pincers handle 71.
The outer surface of pull bar 2 is provided with insulating barrier 21, and the pull bar 2 of peripheral hardware insulating barrier 21 is sleeved in the claw beam 3.The tail end of the top of pull bar 2 and moving binding clip 12 is fixedly linked, and the top of claw beam 3 is fixedly linked with the afterbody extended end 14 of deciding binding clip 11.Can not switch between binding clip 11 and moving binding clip 12, the pull bar 2 in order to ensure deciding, therefore at the afterbody extended end 14 of deciding binding clip 11 and between the insulating barrier 21 of pull bar 2 outer surfaces insulating part 15 is set, between the tail end of the tail end of deciding binding clip 11 and moving binding clip 12, insulating part 16 is set.
The tail end of claw beam 3 is sleeved in the claw beam extension bar 6 and with claw beam extension bar 6 and is fixedly linked, fixedly install claw beam positioning sleeve 5 in claw beam extension bar 6 outer surface of front end, claw beam positioning sleeve 5 is arranged in the inner chamber of insulator cap 41, and claw beam extension bar 6 seamlessly is sleeved in the runner shaft 44.After runner 42 tightened insulator cap 41 with respect to insulation, claw beam positioning sleeve 5 seamlessly was clamped between insulator cap 41 and the insulation runner 42 (along the direction of central shaft), and therefore, claw beam extension bar 6 can not produce relative rotation between the runner 42 with insulating; Thereby realize that insulation runner 42 drives the rotation of claw beam extension bar 6 and claw beam 3; After unscrewing insulator cap 41, the two ends of claw beam positioning sleeve 5 just no longer are insulated medicated cap 41 and insulation runner 42 clamps, and claw beam extension bar 6 can be extracted in runner shaft 44 at this moment.
The tail end of pull bar 2 passes claw beam 3 successively and claw beam extension bar 6 backs are rotatedly connected with draw-bar seat 23, and be specially: the tail end at pull bar 2 is provided with spherical protuberance 22, is provided with the recess that matches with spherical protuberance 22 on draw-bar seat 23; Rely on cooperating of spherical protuberance 22 and recess, thereby realize the tail end of pull bar 2 and being rotatedly connected of draw-bar seat 23.This draw-bar seat 23 is fixedly linked with insulation forceps major handle 72, promptly can drive draw-bar seat 23 by rotation insulation forceps major handle 72 and move forward and backward.
Opposite polarity preceding electrode 81 and rear electrode 82 are set respectively on the pincers handle 71 before insulation, between pro-electrode 81 and the rear electrode 82 collets 83 are set, thereby electrode 81 rear electrodes 82 electricity are each other isolated before realizing.The two ends of high temperature resistant wire 84 link to each other with draw-bar seat 23 with rear electrode 82 respectively, and draw-bar seat 23, pull bar 2 (comprising spherical protuberance 22) and moving binding clip 12 are electric conductor.Before electrode 81 be conducted runner axle sleeve 43, runner shaft 44, claw beam extension bar 6, claw beam 3 and decide binding clip 11 and be electric conductor with runner axle sleeve 43.
It is above-mentioned that bipolar singly to open the elastic separating plier practical work process as follows:
1, when when deciding caliper that binding clip 11 and moving binding clip 12 form and enters into the position of needs operation, thereby open handle (distance before insulate this moment forceps major handle 72 and the insulation between the pincers handle 71 increases) by rotating insulation forceps major handle 72, insulation forceps major handle 72 drives draw-bar seat 23 and advances, draw-bar seat 23 pushing drawing rods 2 advance, pull bar 2 drives moving binding clip 12 and makes opening action, thereby makes caliper in opened condition.
2, can change and decide binding clip 11 and moving binding clip 12 position in the plane by rotating insulation runner 42, thus the optimum position that obtains performing the operation.Specific as follows: as to rotate insulation runner 42, insulation runner 42 drives insulator cap 41 and claw beam positioning sleeve 5 rotates together, claw beam positioning sleeve 5 drives claw beam extension bar 6, claw beam 3 again and decides binding clip 11 and rotate together, moving binding clip 12 rotates with deciding binding clip 11, and moving binding clip 12 also drives pull bar 2 and rotates with respect to draw-bar seat 23 together.When forwarding suitable angle to, insulation runner 42 stops operating; At this moment, is deciding between binding clip 11 and the moving binding clip 12 at position to be performed the operation.
3, make preceding electrode 81 and rear electrode 82 equal energized, thereby produce corresponding polarity.Rear electrode 82 is conducted with moving binding clip 12 by high temperature resistant wire 84, draw-bar seat 23, pull bar 2 (comprising spherical protuberance 22) successively.Before electrode 81 successively by runner axle sleeve 43, runner shaft 44, claw beam extension bar 6, claw beam 3 with decide binding clip 11 and be conducted.Owing to across insulating barrier 21, so can not produce electric conduction phenomena between claw beam 3 and the pull bar 2 between claw beam 3 and the pull bar 2.Because decide between binding clip 11 and the moving binding clip 12 is insulating part 16 and dielectric pin 13; Therefore decide can not produce electric conduction phenomena between binding clip 11 and the moving binding clip 12.Owing to decide the afterbody extended end 14 of binding clip 11 and between the insulating barrier 21 of pull bar 2 outer surfaces, insulating part 15 be set, therefore decide can not produce electric conduction phenomena between binding clip 11 and the pull bar 2.Because the outer surface of claw beam 3 is provided with insulation sleeve 31, so the outer surface of claw beam 3 can not produce leaky.
Thereby 4, close up handle (distance before insulate this moment forceps major handle 72 and the insulation between the pincers handle 71 is dwindled) by rotating insulation forceps major handle 72, insulation forceps major handle 72 drives draw-bar seat 23 and retreats, draw-bar seat 23 pushing drawing rods 2 retreat, pull bar 2 drives moving binding clip 12 disturbance of making a match and does, and closes up state thereby caliper is.When deciding binding clip 11 and contact energising simultaneously with tissue, will carry out electricity cutting or electricity coagulates to tissue, thereby make operative site finish corresponding treatment with moving binding clip 12.
At last, it is also to be noted that what more than enumerate only is a specific embodiment of the present utility model.Obviously, this utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of this utility model all should be thought protection domain of the present utility model.
