[0037] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0038] An embodiment of the present application provides an ear canal foreign body remover.

[0039] Embodiment 1, as Figure 1-7 shown.

[0040] An ear canal foreign body remover comprises a main rod 1, the outer side of the main rod 1 is covered with a rubber sleeve 4, the front end of the rubber sleeve 4 is an adsorption head 41, the adsorption head 41 is truncated cone-shaped, and the front end diameter is smaller than the rear end diameter, which is convenient for sucking foreign bodies on the one hand, and on the other hand, the foreign bodies are sucked into the adsorption head 41, which is convenient for fixation and prevents the foreign bodies from falling out.

[0041] The main rod 1 includes a plurality of sub-rods 11, and a rotating assembly 12 is installed between two adjacent sub-rods 11. The rotating assembly 12 is used to realize the rotation of the sub-rod 11, thereby changing the shape of the entire main rod 1 so that it can be bent, thereby facilitating entry into the patient's ear canal to remove foreign objects without damaging the patient's ear canal.

[0042] The rotating assembly 12 includes a rotating rod 121, a rotating ear plate 122, a transmission box 123, a pushing airbag 124, a moving plate 125, a push rod 126, and a return spring 127. The rotating ear plates 122 are respectively arranged on the left and right sides of the front end of the sub-rod 11, the inner top of the rotating ear plate 122 is rotatably connected to the rotating rod 121, and the other end of the rotating rod 121 is fixedly connected to the bottom end of the adjacent sub-rod 11, and a transmission box 123 is installed on the front side of the inner cavity of the sub-rod 11, the top surface of the transmission box 123 is open, and the inner cavity of the transmission box 123 is slidably connected to the moving plate 125, and the pushing airbag 124 is arranged between the moving plate 125 and the inner bottom surface of the transmission box 123. 24, the pushing airbag 124 is connected to an external air source for air supply, and the pushing airbag 124 is used to push the moving plate 125 to move up and down along the inner cavity of the transmission box 123. The top of the moving plate 125 is rotatably connected to the push rod 126. One side of the top surface of the transmission box 123 is open. The top of the push rod 126 extends to the outside of the transmission box 123 and is rotatably connected to the bottom end of the adjacent sub-rod 11. The return spring 127 is installed between the top of the rotating box inner cavity and the moving plate 125. A micro air pump is installed at the bottom of the main rod 1. The micro air pump is connected to a plurality of the pushing airbags 124 through an air pipe, and an electromagnetic valve is provided at the end of the air pipe, so that the expansion and deflation of a certain pushing airbag 124 can be accurately controlled. When the pushing airbag 124 is expanded, the moving plate 125 is pushed up. When the pushing airbag 124 is deflated, the moving plate 125 is moved down under the elastic force of the return spring 127. By moving the movable plate up and down, the push rod 126 can be pushed and pulled, and then the push rod 126 can push and pull the bottom end of the adjacent sub-rod 11, so that it rotates around the rotation connection between the rotating rod 121 and the rotating ear plate 122, thereby changing the direction of the sub-rod 11. The pushing airbag 124 is a flexible structure, so that when the angle of the sub-rod 11 is too large, the side wall of the sub-rod 11 touches the patient's ear canal, which will also react to the pushing airbag 124, thereby compressing the pushing airbag 124, thereby preventing the sub-rod 11 and other structures from causing greater damage to the ear canal.

[0043] An ear canal foreign body remover also includes a negative pressure component 2 installed at the bottom of the rubber sleeve 4. The negative pressure component 2 is used to form negative pressure in the main rod 1 to absorb and fix the foreign body.

[0044] The negative pressure assembly 2 includes a fixing ring 21 and a negative pressure tube 22. The fixing ring 21 is installed at the bottom of the rubber sleeve 4, and the negative pressure tube 22 is installed in the middle of the fixing ring 21. The negative pressure tube 22 is connected to the negative pressure. The air inside the main rod 1 is extracted through the negative pressure system connected to the negative pressure tube 22, so that the inner cavity of the main rod 1 is in a negative pressure state, and then the foreign matter is absorbed through the adsorption head 41. Small foreign matter can be directly sucked into the adsorption head 41, while larger foreign matter can be adsorbed at the end of the adsorption head 41. Then increase the vacuum degree, that is, increase the suction force at the end of the adsorption head 41, and suck the foreign matter into the adsorption head 41 through the suction force of the negative pressure. Then, in the process of removing foreign matter, the corners of the foreign matter will no longer scratch the patient's ear canal.

[0045] An ear canal foreign body remover includes a suction component 3 installed at the front end of the main rod 1 and used in conjunction with a negative pressure component 2. The suction component 3 is suitable for foreign bodies with irregular surfaces. Compared with the suction head 41, the suction end area is smaller and it is easier to suction and fix foreign bodies.

[0046] The suction assembly 3 includes a mounting plate 31, a rotating motor 32, a linear motor platform 33, a telescopic push rod 34, and a suction port 35. The inner cavity of the uppermost sub-rod 11 is provided with a mounting plate 31, the rotating motor 32 is installed in the middle of the mounting plate 31, the linear motor platform 33 is installed at the output end of the rotating motor 32, the telescopic push rod 34 is installed on the slider of the linear motor platform 33, and the output end of the telescopic push rod 34 is installed with a suction port 35, and the suction port 35 is connected to the negative pressure. The suction port 35 is connected to the negative pressure pipe 22 through a pipeline, and the negative pressure pipe 22 is connected to the negative pressure. The rotating motor 32 can drive the linear motor platform 33 to rotate, and the linear motor platform 33 can drive the telescopic push rod 34 to move linearly. Finally, the two cooperate with each other to realize the flexible movement of the suction port 35, so that foreign objects can be aligned from various positions, and the suction port 35 is extended by the telescopic push rod 34, and the suction port 35 uses negative pressure to absorb and fix foreign objects. The suction port 35 is funnel-shaped, so as to be attached to the surface of the foreign matter and absorb the foreign matter.

[0047] An anti-slip ring 411 is provided inside the adsorption head 41 . The anti-slip ring 411 is made of rubber and can increase the friction between the adsorption head 41 and the foreign matter to prevent the foreign matter from being sucked into the adsorption head 41 and then being partially dislodged.

[0048] A fixing ring 412 is installed on the top of the adsorption head 41 to further improve the fixing ability of the foreign matter after adsorption.

[0049] The fixing ring 412 includes a fixing block 4121 and a connecting belt 4122. A plurality of fixing blocks 4121 are evenly spaced at the front end of the adsorption head 41, and a connecting belt 4122 is provided between two adjacent fixing blocks 4121. After the foreign matter is sucked into the adsorption head 41, the fixing ring 412 increases the locking ability of the end of the adsorption head 41. When the foreign matter falls out, the additional pulling force of the fixing ring 412 is required.

[0050] The adsorption head 41 is provided with a clamping assembly 5 for clamping foreign matter so that the suction assembly 3 can be aligned with the foreign matter for adsorption and fixation.

[0051] The clamping assembly 5 includes a micro telescopic rod 51, a clamping head 52, an inner connecting rod 53, a driving rope 54, and a micro rope winding machine 55. The micro telescopic rods 51 are respectively installed on both sides of the top of the adsorption head 41, and the clamping head 52 is installed on the output end of the micro telescopic rod 51. The inner connecting rod 53 is arranged on the inner side of the adsorption head 41 directly below the micro telescopic rod 51. The bottom end of the inner connecting rod 53 is rotatably connected to the top of the adjacent sub-rod 11, and the micro rope winding machine 55 is installed in the inner cavity of the adjacent sub-rod 11. The output end of the micro rope winding machine 55 is fixedly connected to the driving rope 54, and the other end of the driving rope 54 is fixedly connected to the top of the inner connecting rod 53. When in use, the two micro telescopic rods 51 drive the clamping head 52 to extend, and then the micro rope winding machine 55 tightens the driving rope 54, and the driving rope 54 is used to pull the end of the inner connecting rod 53, and the two ends of the inner connecting rod 53 move toward each other, thereby shortening the distance between the two clamping heads 52 to achieve the clamping function.

[0052] The front sides of the suction head 41 are equipped with micro cameras 6, which are connected to a display, and the display is placed on the side of the bed or other detection equipment. The micro camera 6 can assist medical staff to operate and remove foreign objects better according to the real-time image in the ear canal.

[0053] When the present invention is used:

[0054] The suction head 41 is inserted into the patient's ear canal. When inserted, the angles of each sub-rod 11 are adjusted according to the actual situation to prevent the device from touching the patient's ear canal. According to the situation of the foreign matter, the foreign matter can be directly sucked, or the foreign matter can be first clamped by the clamping component 5 and then adsorbed.

[0055] When directly sucking foreign matter, the rotary motor 32, the linear motor platform 33, and the telescopic push rod 34 are adjusted according to the position of the foreign matter, so that the suction port 35 extends out to align with the foreign matter, and the suction port 35 uses negative pressure to absorb and fix the foreign matter. Then the telescopic push rod 34 retracts to bring the foreign matter to the end of the suction head 41. At this time, the negative pressure component 2 is started, and the telescopic push rod 34 continues to retract synchronously. Through the suction force of the suction head 41 and the pulling force of the suction port, the foreign matter is sucked into the interior of the suction head 41. At this time, the foreign matter can be removed from the patient's ear canal.

[0056] When clamping a foreign object, the two micro telescopic rods 51 drive the clamping head 52 to extend, and then the micro rope winding machine 55 tightens the driving rope 54, and the driving rope 54 pulls the ends of the inner connecting rod 53, and the two ends of the inner connecting rod 53 move toward each other, and the foreign object is clamped by the two clamping heads 52. Then, the adsorption component is used to absorb the foreign object into the adsorption head 41.
