Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of anal dilator, especially an anal dilator. BACKGROUND
[0002] As an important part of medical devices, the anal dilator plays an irreplaceable role in the clinical application of the anorectal department. Its original intention is to solve the treatment problems of anorectal diseases such as anal stenosis, constipation, hemorrhoids and anal fissure, and also provides great convenience for anal surgery and examination.
[0003] There is an anal dilator on the market, which comprises a supporting ring, and a plurality of anal dilating claws are arranged on the supporting ring to dilate the anus. However, each anal dilating claw of the dilator can only be expanded outwardly by the cooperation of the stud and the nut, and all the anal dilating claws cannot be expanded outwardly at the same time, so the working efficiency is low. UTILITY MODEL CONTENTS
[0004] The utility model aims at providing an anal dilator, all the anal dilating claws dilate the anus at the same time, and the working efficiency is improved.
[0005] The anal dilator comprises a supporting ring, a plurality of anal dilating claws that can be opened and closed and are used for dilating the anus of a human body are arranged on the left side of the supporting ring, all the anal dilating claws are hingedly connected to the supporting ring and swing along the center direction of the supporting ring, and a tail plate is fixed to the hinged end of the anal dilating claw.
[0006] Further, the anal dilating claw is six, and the six anal dilating claws are hingedly connected to the supporting ring and are distributed at equal intervals along the circumference thereof.
[0007] Further, a groove is formed in the inner ring of the supporting ring corresponding to each anal dilating claw, and the hinged end of the anal dilating claw is hingedly connected to the groove through a hinge column.
[0008] Further, a limiting protrusion is fixed to the outer side of the head of the anal dilating claw.
[0009] Further, two limiting plates that are symmetrically distributed are fixed to the outer ring of the supporting ring.
[0010] Further, an anti-skid pattern is formed in the outer side wall of the adjusting ring.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] This invention uses an adjusting ring to simultaneously tighten all the tail plates, thereby driving all the anal dilators to dilate the patient's anus at the same time, thus improving the working efficiency of a single controlled anal dilator. Attached Figure Description
[0013] Figure 1 Here is a schematic diagram of the structure of this utility model:
[0014] Figure 2 for Figure 1 Front view structural diagram;
[0015] Figure 3 This is a three-dimensional structural diagram of the present invention;
[0016] The components in the diagram are named as follows: 1. Anal dilator claw; 2. Limiting protrusion; 3. Limiting plate; 4. Adjusting ring; 5. First locking tooth; 6. Tail plate; 7. Support ring. Detailed Implementation
[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
[0018] Example
[0019] The anal dilator described in this embodiment, such as Figures 1 to 3 As shown, it includes a support ring 7. On the left side of the support ring 7, there are 6 openable and foldable anal dilators 1 for dilating the human anus. All anal dilators 1 are hinged to the support ring 7 and swing along the center direction of the support ring 7. The 6 anal dilators 1 are hinged to the support ring 7 and are distributed at equal intervals along its circumference. Corresponding to each anal dilator 1, a groove is opened on the inner ring of the support ring 7. The hinged end of the anal dilator 1 is hinged in the groove through a hinge post.
[0020] During manufacturing, hinge holes are formed on the side walls of the grooves at both ends of the corresponding hinge pins. These hinge holes are blind holes. The hinge ends of the anal dilators 1 also have hinge holes, and the hinge pins are independently installed within these holes. Thus, when all the anal dilators 1 are installed on the support ring 7, they open simultaneously to dilate the patient's anus. During manufacturing, the support ring 7 is divided into two mounting rings, left and right, along the center line of the hinge holes. This allows all the hinge pins to be installed in their corresponding hinge holes. After all the hinge pins are installed, the two mounting rings are joined together and secured with screws.
[0021] The outer side of the head of the dilator claw 1 is fixed with a limiting block 2. The purpose of the limiting block 2 is to limit the withdrawal of the dilator claw 1 from the anus to a certain extent through the limiting block 2 after the head of the dilator claw 1 is inserted into the anus of the patient during the treatment process.
[0022] As shown in the drawings, the tail plate 6 is fixed to the hinged end of the dilator claw 1; all the tail plates 6 are in the state of expanding to the right side when all the dilator claws 1 are in the state of folding, a plurality of first locking teeth 5 are arranged on the outer side wall of each tail plate 6 along the length direction, and the same adjusting ring 4 is sleeved on all the tail plates 6, and the second locking teeth corresponding to each tail plate 6 are fixed on the inner ring of the adjusting ring 4 and are engaged with the first locking teeth 5. Figure 1
[0023] As shown in the drawings, when all the dilator claws 1 are in the state of folding and all the tail plates 6 are in the state of expanding to the right side, the adjusting ring 4 is close to the supporting ring 7 at this time, and as the adjusting ring 4 gradually moves to the right side, all the tail plates 6 are continuously tightened by the adjusting ring 4 and are folded to the inner side, and at the same time, the dilator claw 1 at the other end is expanded due to the folding of the tail plate 6, and at this time, if all the dilator claws 1 are inserted into the anus, the anus can be expanded. Figure 2
[0024] After the adjusting ring 4 moves to the right, the adjusting ring 4 cannot move to the left due to the constraint of the first locking teeth 5 and the second locking teeth, that is, the tail plate 6 cannot be expanded, and the dilator claw 1 also cannot be folded, and the expansion of the anus of the patient is continuously maintained. When the dilator claws 1 are folded, the adjusting ring 4 can be rotated to make the second locking teeth deviate to one side and be unlocked from the first locking teeth 5, at this time, the adjusting ring 4 can move to the left, the tail plate 6 is not constrained by the adjusting ring 4, and the tail plate 6 is expanded by itself under the condition that the dilator claw 1 is pressed by the anus, the dilator claw 1 is folded at the same time, and the dilator claw 1 is taken out of the anus of the patient.
[0025] The outer ring of the supporting ring 7 is fixed with two limiting plates 3 which are symmetrically distributed. The outer side wall of the adjusting ring 4 is provided with anti-skid lines. When in use, the medical staff needs to control the supporting ring 7 with one hand, and adjusts the adjusting ring 4 with the other hand during the left and right movement of the adjusting ring 4, and the limiting plates 3 and the anti-skid lines can play the role of anti-skid during the process.
[0026] In the actual use process:
[0027] The medical staff applies lubricating oil to the head of the dilator claw 1, inserts all the dilator claws 1 into the anus of the patient, adjusts the adjusting ring 4 to move to the right side, makes all the tail plates 6 shrink to the inner side, and then all the dilator claws 1 expand to the outer side to support the anus of the patient, so that the working efficiency is improved.
