Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 4 and give, handle including upper and lower direction, arc and opening holding tank 2 up have been seted up to 1 upside of handle, axial round pin axle 3 articulates around in holding tank 2 has the connecting rod 4 of shape of falling T, holding tank 2 and threaded connection have to stretch out to connecting rod 4 upper end about the holding tank 2 and the cone 5 big end down, 5 upper ends of cone are equipped with the drag hook 6 of the shape of falling U, 6 free ends of drag hook are equipped with fan-shaped and big end down's separation plate 7, the rectangular channel 8 of left and right directions is seted up to 1 downside of handle, axial guide bar 9 about 8 internal rotations are connected with in the rectangular channel, the left and right sides is equipped with wire rope 10 respectively on the guide bar 9, wire rope 10 free end stretches into in holding tank 2 and is connected with connecting rod 4 lower extreme, round pin axle 3 is located between two wire rope 10.

In order to facilitate the rotation of the guide rod 9, a worm wheel 11 is coaxially arranged on the guide rod 9, a worm 12 meshed with the worm wheel 11 is connected in the rectangular groove 8 in a rotating mode, a rotating wheel 13 positioned above the rectangular groove 8 is coaxially arranged at the upper end of the worm 12, and the front end of the rotating wheel 13 penetrates through the handle 1 and is connected with the handle 1 in a rotating mode.

In order to facilitate the wire rope 10 to better pull the connecting rod 4, the left side and the right side in the rectangular groove 8 are respectively provided with a front axial direction reversing wheel 14 and a rear axial direction reversing wheel 14, and the wire rope 10 is in surface contact with the outer edge surfaces of the reversing wheels 14 on the corresponding sides.

In order to facilitate holding the handle 1, a plurality of annular anti-slip strips 15 which are uniformly distributed along the vertical direction are arranged on the outer edge surface of the handle 1.

In order to facilitate the rotation of the runner 13, a plurality of anti-slip grooves 16 are formed on the outer edge surface of the runner 13, and the anti-slip grooves are uniformly distributed along the circumferential direction and are in the vertical axial direction.

When the utility model is used, firstly, medical staff holds the handle 1, and the handle 1 is provided with the anti-slip strip 15, so that the handle 1 can be better held, the sliding is avoided, the operation on the axillary vein of a patient is convenient, and then the draw hook 6 is inserted into the axillary vein tissue of the patient through the handle 1, the draw hook 6 is promoted to hook the axillary vein of the patient, and the separating plate 7 is arranged, so that the axillary vein is protected conveniently, more axillary veins can be pulled up conveniently, and meanwhile, the medical staff can effectively clean the tissue below the axillary vein of the patient;

when the angle of the drag hook 6 needs to be adjusted to adapt to surgical incisions with different shapes, firstly, the rotating wheel 13 is rotated clockwise, and the anti-skid groove 16 is formed in the outer side of the rotating wheel 13, so that the rotating wheel 13 is convenient to rotate, the worm wheel 13 drives the worm wheel 11 to rotate clockwise through the worm 12, the worm wheel 11 drives the guide rod 9 to rotate clockwise, the guide rod 9 drives the left steel wire rope 10 to wind on the guide rod 9 through the left reversing wheel 14, the left steel wire rope 10 pulls the connecting rod 4 to swing downwards along the accommodating groove 2 through the pin shaft 3, the connecting rod 4 drives the drag hook 6 to swing leftwards through the cone 5, meanwhile, the right end of the connecting rod 4 drives the right steel wire rope 10 to move upwards, in the process, the steel wire rope 10 is always in a tightening state, when the drag hook 6 needs to swing rightwards, the rotating wheel 13 is rotated anticlockwise, the operations are repeated, and the structure of the worm wheel 11 and the worm 12 has certain self-locking performance, the draw hook 6 can be in a stable angle, so that the axillary vein of a patient can be conveniently hooked up, and the workload of medical care personnel is increased;
