Detailed Description

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

By figure 1 to 5, main part 1 including upper and lower axial, coaxial sliding connection has drive ring 2 in main part 1, the coaxial groove of stepping down 3 of having seted up of drive ring 2 lower extreme, sliding connection has piston 4 in the groove of stepping down 3, the coaxial feed ring 5 that is equipped with in drive ring 2 upper end, 5 female connection of feed ring has turning block 6, turning block 6 lower extreme is connected with piston 4 upper end through stay cord 7, it has cardboard 8 of upper and lower direction to articulate respectively on the wall of main part 1 left and right sides, sliding tray 9 of upper and lower direction has been seted up on cardboard 8, drive ring 2 left and right sides articulates respectively has the arm-tie 10 that inserts in its corresponding side sliding tray 9, sliding connection has the drive post in the sliding tray 9, the drive post rotates with arm-tie 10 and is connected.

In order to facilitate the sliding of the driving ring 2, the driving ring 2 is provided with moving grooves 11 on the left and right sides, respectively, the main body 1 is provided with clamping blocks 12 on the left and right sides, respectively, and the clamping blocks 12 are inserted into the moving grooves 11 on the corresponding sides, and are connected with the moving grooves 11 in a sliding manner.

In order to limit the driving ring 2, two limiting holes 13 which are penetrated through from front to back are formed in the main body 1, a limiting column 14 which can be inserted into the limiting holes 13 is connected to the driving ring 2 in a sliding mode, and the rear end of the limiting column 14 is connected with the driving ring 2 through a spring 15.

In order to facilitate the resetting of the piston 4, the piston 4 is connected with the side wall of the abdicating groove 3 through a pressure spring 16.

In order to facilitate the rotation of the rotating block 6, a plurality of auxiliary rods 17 are uniformly distributed on the rotating block 6 along the circumferential direction.

In order to facilitate the observation of medical staff, the piston 4 is provided with a probe 18.

When the utility model is used, the initial position of the piston 4 is below the hinge point of the clamping plate 8, the medical staff stretches the main body 1 into the auditory meatus or nasal cavity of a patient, when the medical staff observes through the probe 18, the medical staff holds the main body 1 after foreign matters in the auditory meatus or nasal cavity of the patient contact with the piston 4, then the auxiliary rod 17 is utilized to rotate the rotating block 6 clockwise, and the rotating block 6 moves upwards under the action of the thread;

in the process that the rotating block 6 moves upwards, the rotating block 6 drives the piston 4 to move upwards through the pull rope 7, the piston 4 presses the pressure spring 16, in the process that the piston 4 moves upwards, medical staff gradually move the main body 1 inwards according to the condition of the probe 18 to enable foreign matters to be always contacted with the lower end of the abdicating groove 3, and the movement of the piston 4 enables the inside of the abdicating groove 3 to generate negative pressure, so that a small part of the foreign matters are sucked into the abdicating groove 3 under the action of the negative pressure;

when the piston 4 moves upwards to the limit position, at the moment, the medical staff stops rotating the fixture block 12 and pulls the fixture block 12 upwards, under the action of the threads, the fixture block 12 drives the driving ring 2 to move upwards, the driving ring 2 drives the foreign matters to move upwards through the piston 4 and the abdicating groove 3, the driving ring 2 enables the limit post 14 to press the side wall of the limit hole 13, the limit post 14 moves backwards and compresses the spring 15, and the limit post 14 moves out of the limit hole 13 on the lower side;

in the upward movement process of the driving ring 2, the clamping plates 8 are in contact with the outer side wall of the driving ring 2, the pulling plate 10 drives the driving column to move upward along the sliding groove 9, when the driving ring 2 is positioned above the hinge point of the clamping plates 8, the pulling plate 10 is positioned at the limit position of the sliding groove 9 at the moment, medical staff continuously pulls the rotating block 6, the lower ends of the pulling plates 10 swing inward, in the swinging process of the pulling plates 10, the driving column is hinged with the pulling plates 10 and is in sliding connection with the clamping plates 8, so that the lower ends of the two clamping plates 8 synchronously swing relative to each other in the swinging process of the pulling plates 10, the two clamping plates 8 shield the opening of the main body 1, and therefore shielding support is carried out below foreign matters;

when the limiting column 14 is inserted into the limiting hole 13 on the upper side, the lower ends of the two clamping plates 8 move to the limit position, the lower end of the foreign matter is restrained, and the medical staff pulls the main body 1 upwards to take out the foreign matter from the auditory meatus or the nasal cavity of the patient.

The utility model discloses simple structure, convenient operation, the design is novel, and the practicality is strong, thereby medical staff rotates the commentaries on classics piece and carries out the negative pressure attraction to the foreign matter, prevents that medical staff from when taking out the foreign matter, thereby presss from both sides the bits of broken glass with the foreign matter because of the dynamics is too big to can be with the complete taking out of foreign matter, when attracting the foreign matter to the main part in, medical staff stimulates the drive ring and can make the cardboard support the foreign matter end again, prevents that the foreign matter from droing.
