In the figure: 1-operation handle, 2-connecting pipe, 3-electric coagulation hook, 4-sleeve, 5-snap ring, 6-twist ring, 7-fixed ring, 8-ball, 9-annular limit groove, 10-annular chute, 11-fixture block, 12-slider.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-2, the present utility model provides a technical solution: the utility model provides an electricity congeals hook under thoracoscope that can turn to, includes handle 1, connecting pipe 2 and electricity congeals hook 3, sleeve pipe 4 has been cup jointed to the lateral wall of connecting pipe 2, the left end of sleeve pipe 4 is sealed form, electricity congeals hook 3 fixed mounting in the left end of sleeve pipe 4, electricity congeals hook 3's shape for hook-shaped, the right end of connecting pipe 2 and handle 1 fixed mounting, the lateral wall fixed mounting of handle 1 has snap ring 5, snap ring 5 cup joints on connecting pipe 2, twist ring 6 is installed in the lateral wall rotation of snap ring 5, twist ring 6 and sleeve pipe 4 fixed mounting, be provided with spacing subassembly between twist ring 6 and the handle 1.

Through rotating the twisting ring 6, the twisting ring 6 drives the sleeve 4 to rotate on the connecting pipe 2, so as to drive the electric coagulation hook 3 to rotate, and the electric coagulation hook 3 can be rotated under different conditions to operate.
