[0006] Therefore, the purpose of the utility model is to provide a straw-type curette that can be changed in multiple angles, which solves the problem that during the use of the straw-type curette with adjustable angle direction used in the prior art for otolaryngology, the air suction port is easily blocked by large foreign objects, resulting in the inability to perform suction work. The curette needs to be taken out and the air suction port needs to be cleaned before it can be used again, which is very inconvenient and will aggravate the patient's discomfort.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A straw-type scraper capable of changing directions at multiple angles, comprising a handle and a straw, wherein a support ring is fixedly arranged on the inner side of the upper end of the handle, a rotating ball is rollably sleeved between the support ring and the inner wall of the handle, the straw is fixedly arranged on the upper side of the rotating ball, and a scraper head is fixedly arranged on the top end of the straw;

[0009] A Y-shaped channel is provided inside the rotating ball, first cavities are provided at both ends of the handle, a plurality of through slots are provided between the two first cavities, and an air intake pipe is fixedly provided at the lower end of the handle;

[0010] A ejector pin is arranged inside the straw, a conical groove is provided at the bottom of the first cavity on the upper side, a ball is fixedly arranged at the lower end of the ejector pin, the ball abuts against the conical groove, a second cavity is arranged inside the lower end of the rotating ball, and a reset mechanism for driving the ejector pin to reset is arranged inside the second cavity.

[0011] Preferably, the reset mechanism includes a block and a spring, the block is slidably arranged inside the cavity, the block is fixedly sleeved on the lower end of the ejector pin, the spring is movably sleeved on the rod wall of the ejector pin, one end of the spring is fixedly connected to the upper surface of the baffle, and the other end of the spring is fixedly connected to the inner wall of the second cavity.

[0012] Preferably, a push plate is fixedly sleeved on the outer wall of the lower end of the straw, and a thumb groove is formed at one end of the push plate.

[0013] Preferably, a sealing gasket is fixedly provided on the inner wall of the handle and at a position abutting against the rotating ball.

[0014] Preferably, the outer wall of the handle is provided with anti-slip texture.

[0015] Preferably, the cross-sections of the stopper and the second cavity are both square.

[0016] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0017] 1. The utility model allows the user to hold the handle, insert the thumb into the thumb groove, and rotate the thumb to drive the straw to rotate along with the rotating ball, thereby saving time and effort to adjust the angle of the straw. Moreover, the thumb is used for control, so the control can be more precise.

[0018] 2. The utility model, when the rotating ball rotates, will drive the vertical direction of the ball to move upward along the conical groove. During this period, the conical groove will squeeze the ball upward, and then push the push rod upward, so that the push rod can push away the larger foreign matter blocking the air inlet, thereby effectively preventing the air inlet from being blocked. There is no need to take out the scraper for cleaning, which is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model embodiment discloses a straw-type scraper which can change direction at multiple angles.

[0027] Reference Figure 1-3 A straw-type scraper with multi-angle changeable direction comprises a handle 1 and a straw 3, a support ring 8 is fixedly arranged on the inner side of the upper end of the handle 1, a rotating ball 2 is rolledly sleeved between the support ring 8 and the inner wall of the handle 1, a sealing pad 13 is fixedly arranged on the inner wall of the handle 1 and the part abutting against the rotating ball 2 to improve the sealing performance of the connecting part between the rotating ball 2 and the handle 1, the straw 3 is fixedly arranged on the upper side of the rotating ball 2, a scraper head 4 is fixedly arranged on the top of the straw 3, and an anti-slip pattern is arranged on the outer wall of the handle 1 to increase the friction between the hand and the handle 1 and prevent slipping as much as possible during use;

[0028] A Y-shaped channel 6 is provided inside the rotating ball 2, first cavities are provided at both ends of the handle 1, a plurality of through slots are provided between the two first cavities, and an air intake pipe 5 is fixedly provided at the lower end of the handle 1;

[0029] A thimble 7 is arranged inside the straw 3, a conical groove 12 is provided at the bottom of the upper first cavity, a ball 11 is fixedly arranged at the lower end of the thimble 7, the ball 11 abuts against the conical groove 12, and a second cavity is provided inside the lower end of the rotating ball 2.

[0030] Reference Figure 1-3A reset mechanism for driving the ejector pin 7 to reset is arranged inside the second cavity, and the reset mechanism includes a stopper 9 and a spring 10. The stopper 9 is slidably arranged inside the cavity, and the stopper 9 is fixedly sleeved with the lower end of the ejector pin 7. The spring 10 is movably sleeved on the rod wall of the ejector pin 7. One end of the spring 10 is fixedly connected to the upper surface of the baffle, and the other end of the spring 10 is fixedly connected to the inner wall of the second cavity. The cross-sections of the stopper 9 and the second cavity are both square, so that the stopper 9 cannot rotate, that is, it can slide stably.

[0031] Reference Figure 1-3 The outer wall of the lower end of the straw 3 is fixedly sleeved with a push plate 14, and one end of the push plate 14 is provided with a thumb groove. The thumb is inserted into the thumb groove to control the straw 3 to adjust its angle.

[0032] In the utility model, when in use, the user holds the handle 1, inserts the thumb into the thumb groove in the push plate 14, and rotates the thumb to drive the straw 3 to rotate along with the rotating ball 2, which can save time and effort to adjust the angle of the straw 3, and because the thumb is used for control, the control can be more precise; when the rotating ball 2 rotates in all directions, it will drive the ball 11 to move up along the tapered groove 12 in the vertical direction, during which the tapered groove 12 will squeeze the ball 11 upward, and then push the push rod 7 upward, so that the push rod 7 can push away larger foreign objects blocking the air inlet, thereby effectively preventing the air inlet from being blocked, and there is no need to take out the scraper for cleaning, which is more convenient to use.
