Abstract

The utility model discloses a novel anal dilatation device for the expansion of anus and anal tubes, which comprises a cylindrical body and an outer expansion wide edge. The wide edge is arranged on the near end of the body and the far end of the body is equipped with a hollow anal dilatation cap. The anal dilatation cap comprises a truncated cone-shaped anal dilatation part arranged on the near end thereof, a conical guiding part arranged on the far end thereof and a connection part arranged between the anal dilatation part and the guiding part. The maximal external diameter of the anal dilatation cap is smaller than the external diameter of the body. By utilizing the novel anal dilatation device, the patient's anus and anal tube can be expanded gradually in a controllable manner. The anus sphincter is gradually adapted to the amplitude dilated by the body of the anal dilatation device, thereby avoiding the anal fissure and relieving the pain of patients. Meanwhile, the integrated operation of the pre-amplification of the anus and the anal dilatation is realized by the device of the utility model, thus is simpler and more convenient in usage.

Description

Novel anus dilator

Technical field

This utility model relates to the anus-expanding unit that a kind of surgical operation is used, and belongs to technical field of medical instruments.

Background technology

When anorectal surgical is done inspection, diagnosis or operative treatment, need earlier anus to be strutted, and then put into other and be used to the surgical instruments checking or treat.The surgical instruments that struts anus commonly used at present is an anus dilator seat, the body and the application of force broadside that is positioned at the body afterbody that comprise a cylinder type, its inflexible cylinder type body can strut anus, and the intravital hollow space of cylinder then constitutes other surgical instrumenties and enters the intravital passage of patient.During use, the body of anus dilator seat is slowly inserted anus until anal canal by its front end, because the diameter of the cylinder type body of anus dilator seat bigger (generally reaching more than 30 millimeter) usually, so anus dilator seat is not easy to enter anus.Existing common way is that the doctor can insert patient's anus with finger earlier, and two handss firmly outwards strut then, again anus dilator seat are inserted anus.Because when the doctor used finger pre-expansion anus, the anal sphincter damage patient caused anal fissure because moment exerts oneself excessive through regular meeting, makes patient be subjected to unnecessary injury.

The utility model content

Defective in view of above-mentioned prior art exists can progressively expand the novel anus dilator that anus can be avoided anal fissure thereby the purpose of this utility model is that proposition is a kind of.

The purpose of this utility model will be achieved by the following technical programs:

A kind of novel anus dilator, be used for the expansion of anus and anal canal, comprise the body of cylinder type and the broadside that extends out, described broadside is arranged at the near-end of described body, the far-end of described body is provided with the expansion anus medicated cap of a hollow, described expansion anus medicated cap comprise the truncated cone-shaped that is arranged on its near-end expansion anus portion, be arranged on the conical guide part of its far-end and be arranged on connecting portion between described expansion anus portion and the guide part; The maximum outside diameter of described expansion anus medicated cap is less than the external diameter of described body.

Further, described connecting portion is cylindrical.

Perhaps, described connecting portion is a truncated cone-shaped, and the area of the cross section of the near-end of described connecting portion is greater than the area of the cross section of its far-end.

Perhaps, the cross section of described connecting portion is oval shape or ellipse.

Further, described body is provided with being used to undergo surgery and observing or the window of operative treatment of square type or ladder type.

Compared with prior art, the beneficial effects of the utility model are mainly reflected in: can be so that patient's anus and anal canal little by little, controllably increase, make anal sphincter adapt to the amplitude that the novel anus dilator body is strutted gradually, thereby can avoid the generation of anal fissure phenomenon, alleviate patient's misery; Simultaneously, this utility model is with the pre-expansion anus and expand the anus integrated design, makes that the use of product is simple more, convenient.

The specific embodiment

As shown in Figure 1-Figure 3, this utility model has disclosed a kind of novel anus dilator, comprises the body 2 of cylinder type and is arranged at the broadside that extends out 1 of body 2 near-ends.Described novel anus dilator also comprises the expansion anus medicated cap 3 of hollow, expands the far-end that anus medicated cap 3 is arranged at body 2; Expand anus medicated cap 3 comprise the truncated cone-shaped that is arranged on its near-end expansion anus portion 31, be arranged on the conical guide part 32 of its far-end and be arranged on the connecting portion 32 that expands the truncated cone-shaped between anus portion 31 and the guide part 33, the area of the cross section of the near-end of connecting portion 32 is greater than the area of the cross section of its far-end; Expand the external diameter of the maximum outside diameter of anus medicated cap 3 less than body 2.Certainly, connecting portion 32 also can be designed to cylindrical.

Expand anus portion 31 from its far-end to its near-end, internal diameter increases gradually, thereby can play the effect of expanding anus lentamente; The internal diameter of guide part 33 is less, and is conical, thereby is convenient to be inserted into anal, plays the effect of guiding; Connecting portion 32 is elliptical table shape or waist truncated cone-shaped, the contact area that makes apparatus get over anus in entering the process of anus becomes big gradually, thereby play the effect of progressively expanding anus, the anus looks enter in the process of anus slowly clockwise, alternate rotation apparatus repeatedly counterclockwise expanding then, the tissue of anus is relaxed repeatedly, reach and expand the anus purpose, perhaps expand anus portion in front and adorn a miniature vibrating motor, vibrate in musculus expansor, it is lax that muscle is quickened.

Body 2 is provided with being used to undergo surgery and observing or the window 21 of operative treatment of square type or ladder type.

Simply introduce the use of present embodiment below:

At first, guide part 33 is inserted in anus or the anal canal; Then, rotate described novel anus dilator, make anal sphincter lax gradually, reason is that the cross section of connecting portion of the present utility model is oval shape or ellipse, and rotation can make the sphincter of whole anal canal all be relaxed;

Then, insert lentamente and expand anus portion 31, make that anus or anal canal are little by little enlarged; At last, body 2 is inserted into anal, expands the anus operation thereby finish.

After anal sphincter was expanded to suitable size, hollow space insertion sight glass or surgery sewing and cutting machine at body underwent surgery and observe or operative treatment.For example hemorrhoid operation can be drawn in the blood stasis tissue to described body hollow inside from window 21, uses the PPH coinciding machine to carry out the seaming and cutting operation then.

Near-end herein, far-end are to decide according to industry practice, are near-end from the nearly person of doctor when promptly performing the operation, and are far-end on the contrary.

This utility model still has numerous embodiments, and all technical schemes that all employing equivalents or equivalent transformation and type become all drop within the protection domain of the present utility model.
