Abstract
The invention discloses a novel anus dilator for dilating an anus and an anal canal. The anus dilator comprises a cylindrical body and an externally dilated wide edge, wherein the wide edge is formed at the near end of the body, and the far end of the body is provided with a hollow anus dilating cap; the anus dilating cap comprises a circular anus dilating part at the near end, a conical guide part at the far end and a connecting part between the anus dilating part and the guide part; and the maximum outside diameter of the anus dilating cap is smaller than the outside diameter of the body. The novel anus dilator has main advantages that: the anus and the anal canal of a patient can be gradually and controllably enlarged, and the sphincter of the anus gradually adapts to the amplitude spread by the body of the novel anus dilator so as to avoid anal fissure and relieve the pain of the patient; and meanwhile, anus pre-dilation and anus dilation are integrally designed so that the novel anus dilator is easier and more convenient to use.
Description
Technical field
The present invention relates to the anus-expanding unit that a kind of surgical operation is used, belong 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.
Summary of the invention
The defective that exists in view of above-mentioned prior art, thus the objective of the invention is to propose a kind ofly can progressively expand the novel anus dilator that anus can be avoided anal fissure.
Purpose of the present invention 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, beneficial effect of the present invention is 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, the present invention 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, the present invention 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.
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 invention 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.
The present invention still has numerous embodiments, and all technical schemes that all employing equivalents or equivalent transformation and type become all drop within protection scope of the present invention.
