As shown in fig. 1-5, a tongue side drag hook for oral and maxillofacial surgery, including inside cavity and one end for open-ended holding rod 1, holding rod 1 is equipped with the fixed cover of open-ended one end and has connect frame 2 that is linked together, sliding connection has two symmetrical sliders 3 between the both sides of 2 inner walls of frame, one side that two sliders 3 carried on the back mutually all is fixed with connecting rod 4 and the spring 6 that is the U type, the one end that two connecting rod 4 are close to each other all is fixed with splint 5, the one end of spring 6 keeping away from slider 3 and adjacent 2 inner walls of frame fixed connection, be provided with the adjusting part 7 of interval between two sliders 3 of manual regulation on the holding rod 1.

In this embodiment, different with traditional tongue side drag hook, the utility model discloses a two splint 5's cooperation plays the clamping action to the tongue, then stirs through the tongue after the centre gripping, guarantees going on that the operation can be smooth, wherein specifically operate as follows: firstly, medical personnel hold the holding rod 1 with one hand, the whole device is moved and adjusted, the outer frame 2 and the two clamping plates 5 extend into the oral cavity, the tongue thickness of the people is different, so the distance between the two clamping plates 5 can be adjusted, the distance between the two sliding blocks 3 is adjusted through the adjusting component 7, and then the two sliding blocks are matched through the U-shaped connecting rod 4, as shown in figures 3 and 4, the two clamping plates 5 can be driven to be adjusted in position at the moment, so that the device adapts to tongues with different thicknesses, and the clamping effect on the tongues can be ensured under the action of the spring 6, therefore, compared with the prior art, the tongues are not easy to slip, and the device provides guarantee for oral surgery; it should be noted that the device can be reused many times, but a comprehensive disinfection treatment is required before and after each use.

Specifically, the adjusting assembly 7 comprises a push rod 702 movably penetrating through two ends of the holding rod 1, a trapezoidal block 701 is fixedly mounted at one end of the push rod 702 positioned inside the outer frame 2, and inclined planes contacting with the side surfaces of the trapezoidal block 701 are formed on the surfaces, close to each other, of the two sliding blocks 3.

In this embodiment, choose for use push rod 702, trapezoidal piece 701 and the cooperation between two sliders 3, as shown in fig. 4, trapezoidal piece 701 is the inclined plane with the contact surface of two sliders 3, driving trapezoidal piece 701 through push rod 702 and moving the in-process, if trapezoidal piece 701 carries out rectilinear movement along the direction of keeping away from holding rod 1, two sliders 3 can alternate segregation and drive two splint 5 separations this moment, thereby enlarge the interval between two splint 5, the convenience is put into the tongue between two splint 5 this moment, then it is close to holding rod 1 once more to drive trapezoidal piece 701, thereby make two splint 5 be close to each other once more and cooperate the effect of spring 6 to carry out effectual centre gripping with the tongue.

Specifically, the outer surface of the holding rod 1 is provided with a limiting hole 703, and the outer surface of the push rod 702 is fixed with a bump 704 extending to the outside of the holding rod 1 through the limiting hole 703.

In this embodiment, in order to move the push rod 702 conveniently, the moving path of the push rod 702 is limited, and through the cooperation of the limiting hole 703 and the bump 704, when the holding rod 1 is held by a single hand, the thumb contacts with the bump 704 and drives the push rod 702 to move along the holding rod 1 through the bump 704, and meanwhile, the position of the limiting hole 703 ensures that the moving area of the bump 704 is limited, and in the same way, the moving path of the push rod 702 is limited, so that the device can be operated more conveniently to complete the clamping work of the tongue.

Specifically, the other two sides of the inner wall of the outer frame 2 are fixed with slide bars with dovetail-shaped sections, and dovetail grooves matched with the slide bars in a sliding mode are formed in one sides, close to the slide bars, of the two slide blocks 3.

In this embodiment, the slide bar (not shown in the drawings) and the dovetail groove formed in the slider 3 ensure that the slider 3 can smoothly slide inside the outer frame 2, and ensure the stability of the slider 3 in the sliding process, which not only provides a guarantee for the adjustment of the two clamping plates 5.

Specifically, the clamping plate 5 is a rubber plate.

In this embodiment, choose the rubber slab for use to be splint 5, compare with splint 5 of metal material, the metal surface is smooth at first can not appear and the temperature is low arouses the discomfort of patient, the comfort level of tongue when can guaranteeing splint 5 and tongue contact can reduce the damage to the tongue centre gripping simultaneously.
