Abstract

The invention discloses an anal dilator, which comprises a cylindrical body, a tapered guide part and an outwardly expanded wide side, the guide part is connected to the distal end of the body, and the wide side is connected to the The proximal end of the main body, the anal dilator also includes a cylindrical air bag matched with the main body, the air bag is sleeved on the outer surface of the main body, and the air bag is connected to a fluid through a catheter source. The invention can make the patient's anus and anal canal increase gradually and controllably, and can make the anal sphincter adapt to the range that can be stretched by the anal expander seat before inserting the anal expander seat, thereby avoiding the phenomenon of anal fissure occurred, reducing the pain of the patient. The present invention can be widely used in surgical operations.

Description

A kind of anus-expanding unit

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, comprise a columnar body and the application of force convex shoulder that is positioned at the body afterbody, its inflexible cylinder 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, though generally all be to match with the anus-expanding unit inner catheter to enter anus, the far-end that expands anus phase inner catheter still enters anus inadequately easily, fast.Existing common way is that the doctor can insert patient's anus with finger earlier, and two handss firmly outwards strut anus then, again anus dilator seat and inner catheter thereof 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

Defective in view of above-mentioned prior art exists the objective of the invention is to propose a kind of anus-expanding unit that can avoid anal fissure.

Purpose of the present invention will be achieved by the following technical programs:

A kind of anus-expanding unit, be used for the expansion of anus and anal canal, comprise the guide part of columnar body, taper and the broadside that extends out, described guide part is connected in the far-end of described body, described broadside is connected in the near-end of described body, described anus-expanding unit also comprises a columnar air bag that matches with described body, and described Air sac cover is connected to the outer surface of described body, and described air bag is communicated in a fluid source by a conduit.

Further, the length of described air bag equals the length of described body.

Further, the internal diameter of described air bag is 33～35 millimeters.

Further, the internal diameter of described air bag is 34 millimeters.

Further, described anus-expanding unit also comprises at least one support member, and described support member is arranged between described body and the air bag.

Further, described anus-expanding unit comprises four support members, and described support member is the laminated structure of circular arc, and described support member is arranged between described body and the air bag symmetrically.

Further, described fluid source is source of the gas or fluid supply.

Further, described source of the gas is manual inflatable ball.

Further, described conduit is provided with a control valve that is used to control fluidic flow.

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, before inserting anus dilator seat, can make anal sphincter adapt to the amplitude that can be strutted by anus dilator seat, thereby can avoid the generation of anal fissure phenomenon, alleviate patient's misery.

The specific embodiment

Shown in Fig. 1-5, a kind of anus-expanding unit 1 of the present invention comprises the guide part 12 of body 11, taper and the broadside 13 that extends out, and guide part 12 is connected in the far-end of body 11, and broadside 13 is connected in the near-end of body 11; Described anus-expanding unit also comprises a columnar air bag 2 that matches with body 11, and air bag 2 is socketed on the outer surface of body 11, and the length of air bag 2 equals the length of body 11; One end of conduit 21 is communicated in air bag 2 by a seal nipple 23, and the other end of conduit 21 is communicated in a manual inflatable ball 22, thereby makes air bag 2 and manually inflatable ball 22 connections; Be provided with the support member 3 of four circular arc laminated structures between body 11 and the air bag 2 symmetrically, thereby make when air bag 2 is inserted into anal, the lower surface butt on the near-end of support member and money limit, make air bag that the fold phenomenon can not take place or can't enter the anus phenomenon, the support member 3 of greater number also can be set certainly; Conduit 21 is provided with a control valve 24 that is used to control gas flow.Described near-end for when operation from the nearer end of medical worker; Described far-end for when operation from medical worker's end far away.

The internal diameter of air bag 2 equals 34 millimeters, and is suitable with the internal diameter of common anus-expanding unit; Certainly, the internal diameter of air bag 2 also can be designed to 33～35 millimeters.Certainly, also can feed liquid in air bag 2 it is expanded, thereby play the effect of expanding anus, this moment, manually inflatable ball 22 can be substituted by liquor pump.

Simply introduce use of the present invention below: at first, the body 11 of the anus-expanding unit of unaerated is inserted in the patient's anus, because its internal diameter has been significantly smaller than the anus-expanding unit and the inner catheter internal diameter of prior art, so be easy to enter anus; Then, use manual inflatable ball 22 to begin to airbag aeration, air bag 2 expands gradually, reaches to stop inflation behind the maximum gauge.At last, withdraw from anus-expanding unit of the present invention, make air bag and support member thereof stay anal, if air bag can be followed body and outwards be withdrawed from, then live the near-end of support member, make its fixed-site motionless, with the broadside of another hand operated body with a hand, take out body, air bag then can be stayed anus, for entering of other operating theater instruments provides passage or working place, treat the operation finish after, discharge the gas in the air bag, air bag is taken out.

The present invention still has numerous embodiments, and as in order to make air bag better stay anus, by the cylindrical inverted cone etc. that becomes, all employing equivalents or equivalent transformation and all technical schemes of forming all drop within protection scope of the present invention with the shape of air bag.
