Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the present invention, and It is not all, of embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are not doing Go out the every other embodiment obtained under creative work premise, broadly fall into the scope of protection of the invention.

Referring to Fig. 1-3, the present invention provides a kind of technical scheme: a kind of guiding being easy to grip use Pincers, including clamp handle 1, one end of clamp handle 1 is fixedly connected with force hole 2, and the medial surface in force hole 2 is coated with Having skid resistant course, the other end in force hole 2 to be hinged with grip shank 3, the side opening of grip shank 3 is provided with C-shaped channel 4, the side opening of C-shaped channel 4 is provided with through hole, and through hole is suitable with isocon, so can conveniently divide Flow tube can enter in C-shaped channel 4 by through hole, by the setting of C-shaped channel 4 in grip shank 3, allows point The termination of flow tube can be inserted in C-shaped channel 4, such that it is able to reach isocon to enter to the effect in abdominal cavity, C The side of type groove 4 inner chamber is installed with driving box 5, and the bottom of driving box 5 inner chamber is fixedly connected with fixing Folder 6, the top of fixation clamp 6 is plugged with driving motor 7, and driving motor 7 is Nanoelectromechanical, Nanoelectromechanical A diameter of 3.2 millimeters, a length of 7 millimeters, weight is 0.26 gram, can be stable be placed in driving box In 5, for fixing the electric power output that isocon provides stable, and the output shaft of motor 7 is driven to fix even It is connected to the screw mandrel 8 being rotationally connected with fixation clamp 6 inner cavity top, screw mandrel 8 is socketed with screw rod bushing 9, drive The output shaft of motor 7 can drive screw mandrel 8 to rotate, and because the screw rod bushing 9 of screw mandrel 8 surface socket Suitable with screw mandrel 8 so that screw mandrel 8 can drive screw rod bushing 9 enterprising at screw mandrel 8 while rotating Row moves up and down, and the side of screw rod bushing 9 is installed with the displacement running through and extending to driving box 5 side Bar 10, displacement bar 10 be shaped as L-type, displacement bar 10 is fixedly connected with away from one end of screw rod bushing 9 Cushion 11, being shaped as of cushion 11 is U-shaped, and the inside of cushion 11 is filled with damping sponge Bed course, and displacement bar 10 is positioned at the both sides of driving box 5 inner chamber one end and has been fixedly connected with and driving box 5 Inner cavity top and driving box 5 intracavity bottom fix the damping spring 12 of connection, by driving motor 7 and position Move the setting of bar 10, allow driving motor 7 that displacement bar 10 can be driven to move down, such that it is able to will insert The isocon entered to C-shaped channel 4 is fixed, and reaches the effect of fixing isocon, the side of this insertion Formula stablizing very, it is not required that take a substantial amount of time, be the most also avoided that the injury to abdominal viscera, Reduce operative scar, protect the life security of patient to a certain extent, and treatment can also be increased Success rate.

Operation principle: when isocon termination is fed through intraperitoneal by needs, to force hole 2, force is passed through The stress of clamp handle 1, by two grip shank 3 separately, is then inserted into the C of grip shank 3 side by isocon In type groove 4, then open driving motor 7, allow the output shaft driving motor 7 drive screw mandrel 8 to rotate, And because the screw rod bushing 9 of screw mandrel 8 surface socket is suitable with screw mandrel 8 so that screw mandrel 8 is same rotate Time screw rod bushing 9 can be driven to move up and down on screw mandrel 8, thus allow the displacement of screw rod bushing 9 side Bar 10 also can move up and down simultaneously, and then allows the cushion 11 bottom displacement bar 10 can be to being inserted into Isocon in C-shaped channel 4 carries out the purpose gripped, and is finally reached safe being sent into isocon termination Effect to abdominal cavity.

Although an embodiment of the present invention has been shown and described, for those of ordinary skill in the art Speech, it is possible to understand that these embodiments can be carried out without departing from the principles and spirit of the present invention Multiple change, revising, replace and modification, the scope of the present invention is limited by claims and equivalent thereof Fixed.
