Description

Anorectal dilator

[ technical field ] A method for producing a semiconductor device

The utility model relates to the technical field of medical equipment, in particular to the technical field of anorectal expanders.

[ background of the invention ]

When the anorectal surgery is used for examination, diagnosis or operation treatment, the anus needs to be firstly opened, and then other surgical instruments for examination or treatment are placed. The currently common surgical instrument for stretching the anus is an expander, the currently commonly used anal expander is of a straight cylindrical structure, the rigid cylindrical body can stretch the anus, and the hollow part in the cylindrical body forms a passage for other surgical instruments to enter the body of a patient. When in use, the main body of the expander seat is slowly inserted into the anus from the front end to the anal canal, and the diameter of the cylindrical main body of the expander seat is usually larger (generally more than thirty millimeters).

Because the size of the existing dilator is fixed, the dilator seat is not easy to enter the anus, if the dilator is used for dilating the anus forcibly, the patient can feel strong pain, even the anal fissure is caused.

The existing common method is that a doctor firstly inserts fingers into the anus of a patient, then two hands stretch outwards with force, and then inserts the expander seat into the anus.

When a doctor pre-expands the anus with fingers, the anal sphincter of a patient is often injured due to instantaneous excessive force, anal fissure is caused, and the patient is injured inadequately.

[ Utility model ] content

The utility model aims at solving the problems in the prior art and providing an anorectal dilator which can realize slow and gradual anal dilation so as to avoid the condition of anal fissure.

In order to achieve the above object, the utility model provides an anorectal dilator, including hollow round platform shape's guide disc and leading-in body, the leading-in body includes at least two, and is the expansion piece of convex outer peripheral face structure, its characterized in that: the guiding disk is provided with a driving device for driving the guiding body to expand, and the driving device comprises: the device comprises a placing groove arranged at the inner edge of a guide disc, wherein a driving ring is arranged in the placing groove; the sliding rail is arranged at the position of the guide disc and is perpendicular to the circle center of the guide disc, and a sliding block is arranged in the sliding rail in a sliding mode; the upper end of the sliding block is provided with a first hinge seat and a first rotating shaft which is rotatably arranged on the first hinge seat, the driving ring is provided with a second hinge seat and a second rotating shaft which is rotatably arranged at the second hinge seat, and a connecting rod is arranged between the rotating shaft and the second rotating shaft; the lower end of the sliding rail is provided with an opening penetrating through the sliding rail and the guide disc, the opening extends to the edges of two ends of the sliding rail along the sliding direction of the sliding block, and the lower end of the sliding block is provided with a connecting piece which penetrates through the opening and is connected with the expansion piece.

Preferably, the guide disc is further provided with a limiting device for limiting the driving ring to move up and down, the limiting device comprises a rotating drum which is rotatably arranged at the upper end of the guide disc and is close to the placing groove, and a limiting block is arranged on the side edge of the rotating drum and extends to the upper end of the driving ring and is attached to the upper surface of the driving ring. Its advantage lies in through stop device's setting for leading-in body is after the expansion, and leading-in body keeps the expansion state and avoids the effect that the expansion was influenced to the recoil when can.

Preferably, the guide disc is further provided with a through hole, and the through hole is oval or rectangular.

Preferably, the number of the expansion pieces is 4, and the expansion pieces are symmetrically arranged at the lower end of the guide disc.

The utility model has the advantages that: the utility model discloses a drive arrangement's setting can make leading-in body slowly and progressively expand, and this drive arrangement simple structure convenient operation expands simultaneously effectually for anal sphincter adapts to the range that the expander body propped gradually, thereby can avoid the emergence of anal fissure phenomenon, alleviates patient's misery.

Specifically, when the leading-in body is in a non-expansion state and a contraction state, the driving ring is positioned at the upper end of the placing groove, at this time, the leading-in body can be inserted into the anus of a patient due to the fact that the leading-in body is in the contraction state, at this time, the driving ring is pressed downwards through the edge of the handheld guide disc, the driving ring moves downwards, as the driving ring is provided with a second hinged seat and a second rotating shaft connected to the second hinged seat, the second rotating shaft is further connected with a connecting rod, the connecting rod is further connected with a first rotating shaft in the first hinged seat on the slide rail inner slide block at the guide disc, when the driving ring moves downwards, the connecting rod is pressed downwards through the second rotating shaft, meanwhile, the second rotating shaft starts to rotate, the pressed connecting rod simultaneously gives a pressing-down force to the first rotating shaft and a pressing force to the outer end of the guide disc to enable the slide, because the slider lower extreme is connected with the connecting piece that is connected with the expansion piece, make the expansion piece also follow the slip when the slider is gliding for the expansion piece removes to the guiding disk outer end, all outwards removes through whole expansion pieces, and leading-in body expansion during the final effect.

In actual operation, can both realize the effect of the slow expansion of the leading-in body through the edge of handheld guide dish and slowly push down the drive ring, simultaneously when the leading-in body expands to the biggest, the drive ring also just pushes down and moves to the standing groove of guide dish in, at this moment through rotating the rotary drum in the stop device, makes the stopper of rotary drum side rotate to the drive ring upper end, plays limiting displacement, prevents that the leading-in body that enlarges from reducing once more.

The features and advantages of the present invention will be described in detail by embodiments with reference to the accompanying drawings.
