Problems solved by technology

When a doctor examines the anus, it is generally necessary to expand the anus to a certain extent to facilitate the examination of the disease. Doctors generally use an anal dilator to expand the anus. The current anal dilator is more complicated to operate, and the size of the anus is different when it is expanded. Well fixed, easy to cause damage to the patient's anus

Embodiment 1

[0031]Such asfigure 1 As shown: a turntable medical anal dilator, including a fixed base disc 1, a rotating disk 2 for adjusting the degree of expansion, and 5 arc-expanded plates 3 for achieving anal expansion, allowing 5 The arc-expanded plate 3 gradually expands until the degree of expansion reaches the degree of patient acceptable.

[0032]Such asfigure 2 As shown: The fixed base disc 1 includes a substrate 101, a hood 102 on the substrate 101 and an annular disk 103 disposed inside the outer cylinder 102, and a first through hole 105 is provided on the substrate 101, and the annular disk 103 is fixed. On the substrate 101, the inner loop diameter of the annular disk 103 is consistent with the diameter of the on-through hole on the substrate 101. The annular disk 103 is uniformly distributed in the circumferential direction with 5 expansion plate mounting holes 104, and the expanded plate mounting hole 104 is from the upper to the down-circular disk 103 and the substrate 101, the e...

Embodiment 2

[0037]Such asFigure 11 As shown, the medical anal dilator of the present embodiment is substantially identical to the structure in the first embodiment, and the difference is that the expansion plate mounting hole 104 is provided with a slide 107 in the inner wall in the longitudinal direction, and the outer wall of the connecting rod 302 is symmetric setting. There are two flaps 306, and the connecting rod 302 is provided by the expansion plate mounting hole 104, and the two side flaps 306 are disposed in both sides of the dilated plate mounting hole 104, respectively, by the above configuration, can make the connecting rod 302 can be more Coolly move within the expansion plate mounting hole 104.

Embodiment 3

[0039]The medical anal dilator of the present embodiment is substantially the same as in Example 1, and the difference is that the outer wall of the fixed base disc 1 is provided with a scale, and a pointer is provided in the circular cover 201 of the rotary disk 2, by a pointer. And the scale can quantify the degree of expansion, easy to record and control the expansion progress.

[0040]The method of use of medical anal dilators of the present invention is as follows: Division of the dilator before use, so that the arcuate plate of the dilator is in a contracted state, at this time, the head end of the dilated plate can enter an anus very smoothly in the contracted state. After the arc-shaped expansion plate completely enters the anus, the fixed base plate is at the anus. At this time, the rotation disk is rotated by hand, and the pointer and scale can be observed during the rotation, and the rotation can be observed to better control the expansion process. When the patient is slight...

Abstract

The invention relates to a rotary disc medical anal dilator, which comprises a fixed base disc, a rotary disc for adjusting the expansion degree and N arc-shaped expansion plates for realizing anal expansion. The fixed base plate includes a base plate, an outer cylinder covered on the base plate, and an annular plate arranged inside the outer cylinder. Each expansion plate mounting hole of the shaped plate is provided with an arc-shaped expansion plate, and the arc-shaped expansion plate consists of a long Consists of a strip arc plate, a connecting rod and a control handle. The rotating disc includes a round cover and N control blocks arranged inside the round cover. The round cover is composed of a disc and a ring stop. The expansion of the dilator can be adjusted by turning the rotating disc. The degree can be adjusted according to the different bearing capacity of different patients, which is flexible and convenient.

Description

Technical field[0001]The present invention relates to the field of medical device, and more particularly to a turntable medical anal dilator.Background technique[0002]The anus is an opening of the end of the digestive tract in vitro, usually closing, and the expansion is circular during the defecation, and the diameter is about 2-3 cm. The skin of the anus is black, and there is a bag, sweat gland and sebaceous glands, often contracted by muscle, forming a number of radijet wrinkles. When the doctor examines the anus, it is generally necessary to make a certain expansion of the anus, which is convenient to check the condition, the doctor usually expands the anus using anal dilator, and the current anal dilator is more complicated, and the size is not It is easy to fix it, it is easy to harm the patient anus.Inventive content[0003]It is an object of the present invention to solve the disadvantages in the prior art, providing a turntable medical anal dilator, and can adjust the degree...
