Abstract

The utility model relates to an anal dilation device stand, comprising a cylindrical main body and a broad margin positioned at the proximal end of the cylindrical main body. A plurality of hollowed structures are arranged on the broad margin, and a tapered cap is arranged at the distal end of the cylindrical main body, wherein, a gap with a central angle of 180 degrees is arranged on the cylindrical surface between the cylindrical main body and the tapered cap. When in use, the anal dilation device stand can be better used for a non-annular incision hemorrhoid surgery by relaying on the gap on the cylindrical surface without adopting an auxiliary tube, and the anal dilation device stand can reduce the surgical process, which is good for the quick implementation of the surgery and can further reduce the pain of the patient.

Description

A kind of anus dilator seat

Technical field

This utility model relates to the assistive device of a kind of anorectal section, relates in particular to a kind of anus dilator seat.

Background technology

Anus dilator seat is the assistive device a kind of commonly used of anorectal section, and it plays an important role in the check of anorectal section, operative treatment process.The anus dilator seat that comparatively generally adopts is a straight-tube shape structure that has the edge at present, and its edge is controlled by the doctor or the skin closure at direct and anus edge is fixed.The effect of anus dilator seat is to strut anus, for follow-up inspection or treatment are prepared.

But its function of the apparatus of this structure is very single, and for the ease of the use of operation, it also needs to cooperate a piped subsidiary conduit with tapered distal end of circle.Particularly in the hemorrhoids surgical of other than ring type cutting, such situation makes the step of operation various, is unfavorable for the quick enforcement of performing the operation, and has also increased patient's misery indirectly.

Summary of the invention

The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of anus dilator seat is provided.

For realizing a kind of anus dilator seat of the purpose of this utility model, include cylinder body and broadside, broadside is positioned at the near-end of cylinder body, broadside is provided with some engraved structures, far-end in cylinder body has a tapered cap, and wherein: the periphery between cylinder body and the tapered cap is provided with the breach that central angle is 180 degree.

Further, above-mentioned a kind of anus dilator seat, wherein, described engraved structure has two at least.

Further, above-mentioned a kind of anus dilator seat, wherein, described engraved structure is on broadside and equidistantly distributes.

Further, above-mentioned a kind of anus dilator seat, wherein, described broadside excircle is provided with wavy projection.

Again further, above-mentioned a kind of anus dilator seat, wherein, described breach near-end is that transparent material constitutes.

Adopt technical solutions of the utility model, it in use unlike existing anus dilator seat, needs to cooperate the subsidiary conduit with tapered distal end to use.Simultaneously, the central angle that depends on the periphery to be offered is the breach of 180 degree, can allow this utility model come the hemorrhoids surgical that cuts at other than ring type better, has simplified the step of this operation, both be beneficial to the quick enforcement of operation, and can have further reduced patient's misery again.Therefore, this utility model can be well at anal-surgery, and especially the hemorrhoids surgical of other than ring type cutting is used, and is worth promoting in the field.

The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.

Description of drawings

Fig. 1 is the side surface configurations sketch map of anus dilator seat;

Fig. 2 is the schematic top plan view of anus dilator seat;

Fig. 3 is the organigram of broadside;

Fig. 4 is the partial enlarged drawing of Fig. 3.

The implication of each Reference numeral is as follows among the figure:

1 cylinder body, 2 broadsides

3 engraved structures, 4 breach

5 projections

The specific embodiment

A kind of anus dilator seat shown in Fig. 1～4, include cylinder body 1 and broadside 2, broadside 2 is positioned at the near-end of cylinder body 1, broadside 2 is provided with some engraved structures 3, the far-end of cylinder body 1 is provided with tapered cap, and its special feature is: the periphery between cylinder body 1 and the tapered cap is provided with the breach 4 that central angle is 180 degree.Attractive in appearance and firm in order to allow anus dilator seat take into account when offering breach 4, the center line of the non-openwork part on the center line of breach 4 and the broadside 2 at grade.

Further combined with Fig. 3, described engraved structure 3 has three, and engraved structure 3 is on broadside 2 and equidistantly distributes, and is convenient to the stitching of broadside 2 and skin.Further combined with Fig. 4, broadside 2 excircles are provided with wavy projection 5 again, and it is sliding effectively to prevent to occur when the doctor from holding anus dilator seat hands, guarantees that broadside 2 has certain frictional force.Consider that in operation process the doctor is tissues observed better, described anus dilator seat is a double-shot moulding, and its near-end is that transparent material constitutes, and remainder is white or other colors.

Use of the present utility model is roughly as follows: at first anus dilator seat is inserted anal canal, rotate anus dilator seat then, make its breach 4 aim at hemorrhoidal tissue.Sew up the broadside 2 and the skin around the rectum of anus dilator seat then, anus dilator seat is fixed, realize the fixing of anus dilator seat.

Then, play pocket to hemorrhoidal tissue with the breach 4 of looper by drawing together anus device seat, then with Binding Instrument nail anvil and nail bin away from state under put into anus dilator seat, hemorrhoidal tissue is between nail anvil and the nail bin.Subsequently purse wire is drawn Binding Instrument, tighten up purse wire, make the hemorrhoidal tissue of pathological changes all be drawn in the cutter intracavity of Binding Instrument.Fixedly behind the purse wire, regulate Binding Instrument, the distance between nail bin and the nail anvil is dwindled, clamp hemorrhoidal tissue up to nail anvil and nail bin.And then, observe Binding Instrument and whether enter into suitable distance in the anal canal, whether the pointer of Binding Instrument has been in can be pulled the trigger in the scope, is the green area of Binding Instrument indication window, after be sure oing all to enter proper state, gets final product extrusion handle, finishes percussion.

After the percussion, the adjusting instrument adjusting device, promptly adjusting knob makes nail anvil discharge the tissue that clips away from nail bin, then apparatus is slowly withdrawed from anal canal, and suture is cut off, and takes off anus dilator seat, and operation is promptly finished.

By above-mentioned character express also in conjunction with the accompanying drawings as can be seen, behind employing this utility model, it in use unlike existing anus dilator seat, needs to cooperate the subsidiary conduit with tapered distal end to use.Simultaneously, the central angle that depends on the periphery to be offered is the breach 4 of 180 degree, can allow this utility model come the hemorrhoids surgical that cuts at other than ring type better, has simplified the step of whole surgery, both be beneficial to the quick enforcement of operation, and can have further reduced patient's misery again.Therefore, this utility model can be well at anal-surgery, and especially the hemorrhoids surgical of other than ring type cutting is used, and is worth promoting in the field.

Certainly, more than only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, this utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within this utility model scope required for protection.
