first bevel gear

7, 2 upper ends of rectangular block are rotated and are connected with axial pivot 8 from top to bottom, coaxial second bevel gear 9 with first bevel gear 7 meshing that is equipped with on the pivot 8.

In order to facilitate the operation of the medical staff, the upper end of the rotating shaft 8 extends out of the housing 1 and is slidably connected with a sliding barrel 10 with a downward opening.

In order to facilitate the medical staff to limit the second bevel gear 9, the upper end of the shell 1 is provided with a plurality of limiting holes 11 which are distributed along the circumferential direction of the rotating shaft 8 and are in the vertical axial direction, and the front end of the sliding cylinder 10 is provided with a limiting rod 13 which is inverted L-shaped and the lower end of which is inserted into the limiting holes 11.

In order to make the sliding cylinder 10 and the rotating shaft 8 rotate synchronously, the left and right sides of the inner side wall of the sliding cylinder 10 are respectively provided with a sliding chute 14 in the vertical direction, and the left and right ends of the outer edge surface of the rotating shaft 8 are respectively provided with a sliding block 15 which slides in the sliding chute 14 in the vertical direction.

In order to facilitate the operation of the medical staff, the lower end of the sliding cylinder 10 is connected with the shell 1 through a tension spring 16.

In order to facilitate the medical staff to inject liquid into the sacculus 4 so as to play the anchoring role, the catheter 3 is internally provided with a water injection hole 17 with the left-right axial direction, the left end of the water injection hole 17 is communicated with the sacculus 4, the right end of the water injection hole 17 is connected with a water injection pipe 18, and the right end of the water injection pipe 18 is provided with a three-way valve 19.

When the utility model is used, a medical worker puts a part of the catheter 3 with the balloon 4 at the left end into a blood vessel of a patient, when the free end of the catheter 3 touches an intricate blood vessel, the medical worker needs to swing the free end of the catheter 3 forward, the medical worker holds the shell 1 and pulls the sliding cylinder 10 upwards, the tension spring 16 is pulled upwards while the sliding cylinder 10 moves upwards, the tension spring 16 has a downward tension force, the sliding cylinder 10 drives the limiting rod 13 to move upwards, after the catheter moves for a certain distance, the lower end of the limiting rod 13 is far away from the limiting hole 11 and is positioned outside the shell 1, and the limiting of the second bevel gear 9 is released;

at the moment, the medical staff rotates the sliding barrel 10 clockwise, the sliding barrel 10 drives the rotating shaft 8 to rotate clockwise through the sliding block 15, the rotating shaft 8 drives the second bevel gear 9 to rotate clockwise, the second bevel gear 9 drives the first bevel gear 7 on the front side to rotate anticlockwise, the first bevel gear 7 on the front side drives the rotating wheel 5 on the corresponding side to rotate anticlockwise, the rotating wheel 5 on the front side rotates while contracting the pull rope 6, the pull rope 6 drives the free end of the catheter 3 to swing forward, meanwhile, the second bevel gear 9 drives the rotating wheel 5 on the corresponding side to rotate clockwise through the first bevel gear 7 on the rear side, and the rotating wheel 5 on the rear side rotates while releasing the pull rope 6, so that the free end of the catheter 3 swings forward more smoothly;

when the swing angle of the free end of the catheter 3 is proper, the medical staff loosens the sliding barrel 10, at the moment, the sliding barrel 10 moves downwards due to the downward tension of the tension spring 16, the sliding barrel 10 moves downwards and simultaneously drives the limiting rod 13 to move downwards, after moving for a certain distance, the lower end of the limiting rod 13 is inserted into the limiting hole 11 again to limit the second bevel gear 9, at the moment, the medical staff can continue to operate, when the left end of the catheter 3 meets the complicated blood vessel again, the medical staff needs to enable the free end of the catheter 3 to swing backwards, the medical staff repeats the above process, and pulls the sliding barrel 10 upwards to relieve the limit of the second bevel gear 9;

at the moment, the medical staff rotates the sliding barrel 10 anticlockwise, the sliding barrel 10 drives the rotating shaft 8 to rotate anticlockwise through the sliding block 15, the rotating shaft 8 drives the second bevel gear 9 to rotate anticlockwise, the second bevel gear 9 drives the rotating wheel 5 on the corresponding side to rotate anticlockwise through the first bevel gear 7 on the rear side, the rotating wheel 5 on the rear side rotates and simultaneously contracts the pull rope 6, so that the free end of the catheter 3 is driven to swing backwards, the rotating wheel 5 on the corresponding side is driven to rotate clockwise through the first bevel gear 7 on the front side while the second bevel gear 9 rotates, and the pull rope 6 is loosened while the rotating wheel 5 on the front side rotates, so that the free end of the catheter 3 can swing backwards more smoothly;

when the swing angle of the left end of the catheter 3 is proper, the medical staff loosens the sliding barrel 10, the sliding barrel 10 moves downwards due to the tension of the tension spring 16, the sliding barrel 10 drives the limiting rod 13 to move downwards to the lower end to be inserted into the limiting hole 11 again, the limiting of the second bevel gear 9 is realized, the medical staff can continue to operate at the moment, when the medical staff needs to inject water into the balloon 4 to play the anchoring role, the medical staff communicates the injector with the three-way valve 19 and opens the three-way valve 19, the water is injected into the balloon 4 through the water injection pipe 18 and the water injection hole 17, after the balloon 4 is inflated, the medical staff closes the three-way valve 19 and pulls out the injector, when the balloon 4 is not needed to be anchored, the medical staff can suck the water in the balloon 4 completely, and after the operation is finished, the medical staff can take out the catheter 3.

Compared with the prior art, the beneficial effects of the utility model are that: the casing that is equipped with, the rectangle piece, the pipe, the sacculus, first bevel gear, second bevel gear, the runner, the pivot etc, can make medical personnel carry out two-way angle's regulation and anchoring to the free end of pipe at the operation in-process, the process of operation has been accelerated, medical personnel's work load has been reduced, time saving and labor saving, the water injection pipe that is equipped with, the three-way valve, the slide cartridge etc., medical personnel's use of can being convenient for, the gag lever post that is equipped with, spacing hole, the extension spring, medical personnel can be convenient for carry on spacingly to second bevel gear, this simple structure, the design is novel, high durability and convenient use, therefore, the clothes hanger is strong in practicability.
