DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0019] like Figure 1-2 As shown, the utility model is a head fixing device for ENT examination, comprising a seat plate 1, a support assembly is arranged at the bottom of the seat plate 1, a lifting mechanism is arranged on the left side of the top of the seat plate 1, an arc plate 11 is fixedly installed on the upper side of the lifting mechanism, an arc groove 12 is opened on the top of the arc plate 11, a slide plate 13 is slidably mounted inside the arc groove 12, a locking assembly is arranged between the slide plate 13 and the arc plate 11, a connecting rod 14 is fixedly installed on the top of the slide plate 13, and a bar box 15 is fixedly installed on the top of the connecting rod 14;

[0020] A moving block 16 is symmetrically slidably installed inside the strip box 15, and a bidirectional threaded rod 17 is rotatably installed on the inner wall of the rear side of the strip box 15. The front end of the bidirectional threaded rod 17 passes through the two moving blocks 16 in turn and extends out of the strip box 15. A screw block 18 is fixedly installed at the front end of the bidirectional threaded rod 17. The rear moving block 16 is threadedly connected to the reverse-rotation thread section of the bidirectional threaded rod 17, and the front moving block 16 is threadedly connected to the forward-rotation thread section of the bidirectional threaded rod 17. A clamping assembly is installed on the right side of the two moving blocks 16.

[0021] When in use, the patient sits on the seat board. In the initial state, the height of the lifting mechanism is adjusted according to the patient's height so that the two clamping assemblies are located on the upper side of the ear of the patient's head. After the adjustment is completed, the staff rotates the screw block 18, and the bidirectional threaded rod 17 can be rotated by the screw block 18. Since the rear moving block 16 is threadedly connected with the reverse thread section of the bidirectional threaded rod 17, and the front moving block 16 is threadedly connected with the forward thread section of the bidirectional threaded rod 17, the bidirectional threaded rod can rotate forward and backward to drive the two moving blocks 16 to move closer to and away from each other. When the patient's head needs to be clamped, the two moving blocks 16 are controlled to move closer to each other until both clamping assemblies contact the patient's head and apply a certain clamping force. The holding force is used to fix the patient's head. When examining the patient's ears, the patient needs to tilt his head, and the medical staff can release the lock of the locking component. The patient's tilted head can drive the slide plate 13 to slide inside the arc groove 12 until it is adjusted to a suitable angle, and the locking component is used to lock the slide plate 13 again. The position of the slide plate 13 is fixed, and the angle of the patient's head is fixed, and the head will not rotate during the examination. When examining the patient's nose or throat, the patient needs to keep his head tilted back. At this time, the two clamping components can be preferentially released to clamp the patient's head. After the patient finishes tilting his head back, the two clamping components are controlled again to clamp the patient's head so that the patient can keep his head tilted back. It has strong applicability and reliable and convenient clamping.

[0022] The clamping assembly includes an extension rod 19, which is fixedly mounted on the right side of the moving block 16, and a strip clamping block 20 is fixedly mounted on the side of the extension rod 19 away from the strip box 15;

[0023] Cotton pads 21 are fixedly mounted on one side of the two strip-shaped clamping blocks 20 close to each other.

[0024] When the two strip clamps 20 are close to each other, the two cotton pads 21 will first abut against the front and back sides of the patient's head, and the two strip clamps 20 are both located on the upper side of the patient's ears and will not block the patient's ears. The two strip clamps 20 can apply a fixing force to fix the patient's head to prevent the patient's head from shaking, and the cotton pads 21 can avoid pinching the patient.

[0025] The support assembly includes four support columns 22 , which are distributed in a rectangular shape and installed at the bottom of the seat plate 1 ; the four support columns 22 can provide a stable supporting force for the seat plate 1 .

[0026] The locking assembly includes a first threaded rod, a plurality of first threaded connection holes 23 are arc-shapedly opened on the inner wall of the bottom side of the arc groove 12, a second threaded connection hole is opened on the upper side of the slide plate 13, the first threaded rod is threadedly connected to the inside of the second threaded connection hole, the lower end of the first threaded rod is threadedly connected to one of the first threaded connection holes 23, and a rotating block 231 is fixedly installed on the upper end of the first threaded rod.

[0027] When in use, in the initial state, the first threaded rod is threadedly connected to one of the first threaded connection holes 23, so the position of the slide plate 13 is fixed. When the sliding of the slide plate 13 needs to be adjusted, the first threaded rod only needs to be rotated to make the first threaded rod withdraw from the connection with one of the first threaded connection holes 23. After the patient stops tilting his head, the first threaded rod can be connected to the corresponding first threaded connection hole 23 again.

[0028] The lifting mechanism includes a sleeve 24, which is rotatably assembled on the left side of the top of the seat plate 1. The second threaded rod 25 is connected to the internal thread of the sleeve 24. The arc plate 11 is fixedly installed on the upper end of the second threaded rod 25. Telescopic rods 26 are symmetrically installed at the bottom of the arc plate 11. The lower ends of the two telescopic rods 26 are fixedly connected to the top of the seat plate 1, and a turntable 27 is fixedly installed around the sleeve 24.

[0029] When in use, the staff rotates the turntable 27 forward and reversely, and the turntable 27 drives the sleeve 24 to rotate forward and reversely. Since the position of the second threaded rod 25 is limited by the two telescopic rods 26, as the sleeve 24 rotates, the second threaded rod 25 will extend out or enter the sleeve 24, thereby changing the height of the arc plate 11. The operation is simple and convenient.

[0030] According to the above overall description, the utility model can stably clamp the patient's head when in use to prevent the patient's head from moving around and affecting the doctor's examination. After the patient makes movements such as tilting the head or tilting the head, the patient's head can be fixed to keep the patient's head tilted or tilted, which is convenient for the doctor to examine and further improves the doctor's examination efficiency.

[0031] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
