Abstract
The invention relates to an anal fistula plug which is insusceptible to dropping. The anal fistula plug comprises a circular table body implanting section, wherein the large end face of the implanting section is connected with one end of a plug body section; the other end of the plug body section is connected with a bottom surface of a cylindrical stitching area; the plug body section is formed by connecting more than two oblate spheroids; and the stitching area and the plug body section are made of a small intestinal submucosa or an allogenic biological material. According to the anal fistula plug, a plug body consists of a plurality of oblate spheroids, and the axial self-balancing of uniformly-distributed acting force to which the single oblate spheroid is subjected can be realized, so axial force generated by deformation stretching is generated on the integral plug body section only, and is balanced with 'rectal resting pressure' which acts on the large-end face side of the implanting section to avoid operation failure caused by the dropping of the implanting section. Numerical simulation indicates that the axial component force of the anal fistula plug under weight pressure can be reduced greatly, so that the anal fistula plug is prevented from dropping.
Description
Technical field
The present invention relates to a kind of anal fistula bolt, be specifically related to a kind of difficult drop-off anal fistula bolt.
Background technology
Development along with the deep and biomaterial that the anal fistula Therapeutic Method is studied; People are successively applying to biomaterial not of the same race in the anal fistula treatment in recent years, and wherein the most outstanding is exactly anal fistula bolt method, and anal fistula bolt method has not only farthest been preserved the patient's anus sphincter; Avoid patient's postoperative anal incontinence; And postoperative pain is less, can recover the operate as normal life soon, and is consistent with the theory of present minimally invasive surgery.So anal fistula bolt method just enjoys high praise once appearance, become a line art formula of recommending in U.S.'s knot rectal surgery association's anal fistula and the perianal abscess treatment guide.At present the anal fistula bolt generally adopts conical configuration, but the follow up survey of postoperative shows, comes off because the characteristics of its configuration are prone to cause in the use, causes operative failure.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of difficult drop-off anal fistula bolt, have self axially loaded balance, the advantage of difficult drop-off.
In order to achieve the above object, the technical scheme taked of the present invention is:
A kind of difficult drop-off anal fistula bolt comprises Rotary-table implantation section 3, implants the large end face of section 3 and an end of key section 2 and is connected, and the other end of key section 2 is connected with the bottom surface of cylinder suture zone 1.
Described key section 2 is connected and composed by plural oblate spheroid 4.
Described oblate spheroid 4 by a spheroid intercepting end to end the section form, the width of oblate spheroid 4 is the 45%-50% of sphere diameter, oblate spheroid 4 is identical with the diameter of suture zone 1.
The length of described suture zone 1 is adjusted according to the number and the total length of oblate spheroid 4, guarantee except that with suture zone 1 connecting place be half oblate spheroid 4, the appearance of 4 one-tenths integers of all the other oblate spheroids.
The described length of implanting section 3 is the 8%-15% of total length, and the diameter of small end face is 60% of oblate spheroid 4 diameters, and the diameter of large end face is identical with oblate spheroid 4 diameters.
Described suture zone 1 is processed by small intestinal submucosa or allosome biomaterial with key section 2.
Because key section 2 of the present invention is joined by a plurality of oblate spheroids 4 and is constituted; What on single oblate spheroid 4, receive is uniformly distributed with active force and can obtains axial self-balancing; Therefore the axial force that only has distortion to stretch and produce in whole key section 2; And make itself and " the rectum rest pressure " that act on the large end face side of implanting section 3 reach balance, prevent that thus coming off of the section of implantation 3 from causing the problem of operative failure.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done detailed description.
With reference to accompanying drawing, a kind of difficult drop-off anal fistula bolt comprises Rotary-table implantation section 3, implants the large end face of section 3 and an end of key section 2 and is connected, and the other end of key section 2 is connected with the bottom surface of cylinder suture zone 1.
Described key section 2 is connected and composed by plural oblate spheroid 4.
Described oblate spheroid 4 by a spheroid intercepting end to end the section form, the width of oblate spheroid 4 is the 45%-50% of sphere diameter, oblate spheroid 4 is identical with the diameter of suture zone 1.
The diameter of described suture zone 1 is identical with patient's fistula road width, and length is adjusted according to the number and the total length of oblate spheroid 4, guarantee except that with suture zone 1 connecting place be half oblate spheroid 4, the appearance of 4 one-tenths integers of all the other oblate spheroids.
The described length of implanting section 3 is the 8%-15% of total length, and the diameter of small end face is 60% of oblate spheroid 4 diameters, and the diameter of large end face is identical with oblate spheroid 4 diameters.
Described suture zone 1 is processed by small intestinal submucosa or allosome biomaterial with key section 2.
Because key section 2 of the present invention is joined by a plurality of oblate spheroids 4 and is constituted; What on single oblate spheroid 4, receive is uniformly distributed with active force and can obtains axial self-balancing; Therefore the axial force that only has distortion to stretch and produce in whole key section 2; And make itself and " the rectum rest pressure " that act on the large end face side of implanting section 3 reach balance, prevent that thus coming off of the section of implantation 3 from causing the problem of operative failure.Draw the size that the present invention can reduce anal fistula bolt axial component under body weight pressure greatly through numerical simulation, thereby prevent that it from coming off.
