[0039] Embodiment 1

[0040] The present embodiment provides a rotating opening and closing type preheatable vaginal dilator as shown in Figures 1-9 The present embodiment provides a rotating opening and closing type preheatable vaginal dilator as shown in

[0041] The rotating expansion assembly 4 includes a plurality of rotating gears 41 and expansion rods 42. The expansion rod 42 is fixedly arranged at the right end of the rotating gear 41. The rotating gear 41 is engaged with the hand screw wheel 5. Among them, one rotating gear 41 and one expansion rod 42 form a group, and specifically four groups are provided, so that the compression force of the expansion rod 42 on the patient can be reduced during use, thereby better reducing the pain felt by the patient, and also bringing a better expansion angle. The hand screw wheel 5 serves as a driving wheel to drive the rotating gear 41 to rotate. The rotating gear 41 is used to drive the expansion rod 42 to act, so as to realize the expansion or reduction of the rotating expansion assembly 4.

[0042] Further, asFigure 2 As shown in Figure 4 The right end of the mounting seat 3 is provided with four mounting rods 31, which are equidistantly arranged around the mounting seat 3, and the rotating gear 41 is sleeved on the mounting rod 31. Specifically, four mounting rods 31 are arranged at the right end of the mounting seat 3 to facilitate the installation or subsequent replacement of the rotating expansion assembly 4, and the rotating gear 41 is rotatably connected with the mounting rod 31.

[0043] Further, the expansion rod 42 includes a straight rod 421 and an arc-shaped rod 422, the left end of the arc-shaped rod 422 is coaxially arranged with the rotating gear 41, and the straight rod 421 is fixedly arranged at the right end of the arc-shaped rod 422. The rotation of the rotating gear 41 causes the right end of the arc-shaped rod 422 and the straight rod 421 to form a circular motion with the rotating gear 41 as the center, and the straight rod 421 finally plays a supporting role.

[0044] Further, the right side of the mounting seat 3 is fixedly provided with a protective end cover 9, which is provided with a limiting hole 91 at a position corresponding to the expansion rod 42. The rotating gear 41 is arranged between the mounting seat 3 and the protective end cover 9, and the hand screw 5 is arranged at the left end of the protective end cover 9. A protection area is formed between the protective end cover 9 and the mounting seat 3 for placing the rotating gear 41 and plays a limiting role to prevent the rotating gear 41 from falling off, and also prevents the hand screw 5 from moving axially to the right end. The limiting hole 91 provided on the protective end cover 9 allows the expansion rod 42 to pass through the protective end cover 9 and ensures that the left end of the expansion rod 42 can move in the limiting hole 91 without tilting. At the same time, the protective end cover 9 can also protect the patient from being injured by the sharp end of the rotating gear 41.

[0045] Further, as shown in Figure 4 The upper end of the mounting cylinder 2 is fixedly provided with an elastic buckle 21, and the elastic buckle 21 is fixedly provided with an inclined gear position clamping block 211.

[0046] A plurality of gear position clamping slots 51 corresponding to the gear position clamping block 211 are equidistantly arranged on the hand screw 5. During use, the gear position clamping block 211 will always be located in the gear position clamping slot 51, and the inclined gear position clamping block 211 will automatically pop into the gear position clamping slot 51 of the hand screw 5 when the hand screw 5 is rotated to increase the required gear position. When it is necessary to reduce the expansion gear position, the elastic buckle 21 can be automatically reduced to a low gear by simply pressing it down. The gear position clamping block 211 actually also plays a supporting role on the overall structure, so that after the gear position is expanded, the dilator will not automatically retract to reduce the gear position due to pressure. There are currently four gear position clamping slots 51, i.e. there are four gear positions in total. The hand screw 5 can be rotated four times to fully open the instrument, and more gear positions of the hand screw 5 can be replaced according to the needs to control the opening amplitude between each gear position.

[0047] Further, the rotating gear 41 is an incomplete gear, and an intermittent stroke is arranged on the rotating gear 41. When the medical worker forgets that the maximum gear has been reached and continues to rotate, the intermittent stroke can make the hand rotating wheel 5 unable to drive the rotating gear 41 to rotate, thereby reminding the medical worker that the maximum gear has been reached.

[0048] Further, the rotating gear 41 is a bevel gear, and the end face close to one end of the expansion rod 42 is smaller than the end face of the other end. The inner circle of the hand rotating wheel 5 is provided with internal teeth matched with the rotating gear 41. The arrangement of the bevel gear makes the rotating gear 41 apply an axial force to the left of the hand rotating wheel 5, and the protection end cover 9 cooperates to limit the axial position of the hand rotating wheel 5.

[0049] Further, the rotating expansion assembly 4 is fixedly provided with a heating assembly 6.

[0050] The mounting cylinder 2 is fixedly provided with a lighting assembly 7.

[0051] The back of the lower end of the handle 1 is provided with a power supply 8 for supplying power to the heating assembly 6 and the lighting assembly 7. The mounting cylinder 2 is used to fix the lighting assembly 7, the heating assembly 6 is built-in in the rotating expansion assembly 4, and the handle 1 is used to bear the wires connecting the power supply 8 with the heating assembly 6 and the lighting assembly 7.

[0052] Further, the heating assembly 6 includes an electric heating wire 61, one end of which is fixedly arranged in the mounting cylinder 2, and the other end is fixedly arranged in the inside of the expansion rod 42 through the mounting seat 3 and the mounting rod 31. The electric heating wire 61 is powered by the power supply 8 and is used to preheat the expansion rod 42 as a whole before use, and can be gradually heated to 30-35℃, so that the patient can be examined in a more comfortable temperature close to the human body, and the discomfort caused by the cold instrument is avoided.

[0053] Further, a plurality of lamp holes 22 are equidistantly arranged close to the right side of the mounting cylinder 2. The lighting assembly 7 includes a plurality of equidistantly arranged L-shaped lamp rods 72 and lamp beads 71. The left end of the lamp rod 72 is fixedly arranged on the outer circle of the mounting cylinder 2, the right end of the lamp rod 72 is arranged through the lamp hole 22, and the lamp bead 71 is fixedly arranged on the right end of the lamp rod 72. Specifically, there are four groups of lamp beads 71 and lamp rods 72, which can provide better light conditions for observation. The lamp holes 22 arranged on the mounting cylinder 2 can make the right end of the lamp rod 72 extend out of the mounting cylinder 2 and install the lamp bead 71 into the observation area of the instrument. The lamp bead 71 minimizes the visual field shielding while the light can directly fill the observation area, providing the maximum lighting condition for the medical worker and solving the disadvantage of needing another person to assist in lighting.

[0054] In use, the instrument is in a closed state, first open the power 8, turn on the lighting assembly 7 and heating assembly 6, the heating assembly 6 preheats the instrument, the temperature of the rotating expansion assembly 4 is increased, after the temperature is appropriate, the medical worker can put the instrument into the patient's body by holding the handle 1, then directly rotating the hand screw 5 can increase the gear, reducing the gear only needs to directly press the elastic buckle 21, the elastic buckle 21 can prevent the instrument from being automatically reduced under pressure during the examination, at this time the medical worker can observe the patient's condition through the lighting assembly 7, and according to the actual need, the required gear is increased or reduced, after the examination, the medical worker presses the elastic buckle 21, the hand screw 5 will automatically return to the lowest gear, then the instrument is taken out and the power is turned off to complete the operation.

[0055] The above is a further detailed description of the utility model in combination with specific preferred embodiments, and the specific implementation of the utility model cannot be limited to these descriptions. For ordinary skilled persons in the technical field to which the utility model belongs, without departing from the concept of the utility model, a number of simple deductions or substitutions can be made, which should be regarded as belonging to the protection scope of the utility model.
