Medical multi-functional self-fixing anal canal

Technical Field

The utility model relates to the field of medical equipment, in particular to medical multi-functional from fixed anal canal.

Background

In colorectal surgery, a part or all of the rectum is often cut off to perform anastomosis of the distal and proximal intestinal tracts, and in order to reduce the pressure of intestinal contents on an anastomosis port, the anal canal is often placed through the anus to reduce the pressure, drain the intestinal contents and support the distal and proximal intestinal tracts of the anastomosis port. Because of the special position and structure of the anus, the anal canal often has no better fixing method. The current clinical common method of suture or adhesive tape fixation has unsatisfactory actual effect, brings great pain to patients and also influences postoperative activities.

After a distal rectal or anal canal operation, such as a local excision of a benign and malignant tumor of the rectum or a hemorrhoid operation, sometimes a condition of heavy bleeding occurs, a putty gauze packing is a more common and effective method. Because the internal diameters of the rectum and the anal tube are different and the anus is used for defecation and air exhaust, the clinical practice is often not ideal.

There are also solutions to achieve fixation and compression hemostasis after colorectal surgery, such as hemorrhoid compression hemostat disclosed in chinese utility model patent No. cn201020219014.x with application date of 2010, 06, 08 and publication date of 2010, 12, 15, which is adapted to the physiological structure of anorectum, and includes a hollow catheter as anal canal, an inflatable expansion balloon and a filling tube for inflating the expansion balloon. Wherein the inflatable bladder comprises three continuous portions of a large end, a middle section and a small end. When in use, the inflation bag is inflated by injecting gas or water or ice mountain through the filling tube, so that the inflation bag is expanded, and the purpose is to attach the inflation bag to the internal hemorrhoid area, the external hemorrhoid area and the mixed hemorrhoid area, expand, extrude, tightly embed and press the anal canal, the upper part and the lower part of the anal canal, and achieve the function of compression hemostasis. However, due to individual differences, the post-operative rectal end shapes and sizes of different patients are different, and the internal anal circumference states are also different, so that the inflation states of the large end and the middle section of the inflatable bag are also different, and the practical use effect of the scheme is not ideal.

At present, no clinical application of the hemostatic bandage can realize fixation and compression hemostasis after colorectal surgery.

Detailed Description

The medical multifunctional self-fixing anal canal of the present invention will be described in detail with reference to the following embodiments and accompanying drawings.

Referring to fig. 1, in the first embodiment, the medical multifunctional self-fixing anal canal of the present invention mainly comprises an anal canal 10 and a multifunctional component 20. The anal tube 10 and the multifunctional component 20 can be separately connected, so that the medical multifunctional self-fixing anal tube after being combined can be used as required by a doctor, and the anal tube 10 or the multifunctional component 20 can be detached to be independently selected.

The anal canal 10 has a structure substantially the same as that of the existing anal canal, and has two through ends, a first end 11 and a part near the first end for extending into the human body, and a second end 12 and a part near the second end for remaining outside the human body. A plurality of drainage holes 13 which penetrate through the wall part of the anal tube 10 are formed at the position of the anal tube 10 close to the first end of the anal tube for realizing drainage and ventilation. In particular, the anal canal 10 is formed with one or more protrusions 14 as snap features near its second end 12. The anal canal 10 is preferably made of a silicone material, which is not easy to cause skin allergy. When a plurality of protrusions 14 is provided, the plurality of protrusions 14 may be in one or two or three rows extending in the direction of extension of the anal canal 10.

The multifunctional member 20 mainly comprises a sleeve 21 detachably fitted over the anal canal 10, a first cavity 22, a second cavity 23 and a third cavity 24 formed on the outer periphery of the sleeve 21, and a first conduit 25, a second conduit 26 and a third conduit 27 respectively connected to the first cavity 22, the second cavity 23 and the third cavity 24. The first, second and third cavities 22, 23 and 24 are not communicated with each other in their inner spaces, and are communicated with the outer space only through the first, second and third pipes 25, 26 and 27, respectively.

In this embodiment, the sleeve 21 is made of silicone material, and the inner diameter thereof is substantially equal to or slightly larger than the outer diameter of the anal canal 10 so as to facilitate inserting the anal canal 10. The first cavity 22, the second cavity 23 and the third cavity 24 are formed on the outer periphery of the sleeve 21 in a sequential manner from the first end 211 of the sleeve 21 to the second end 122 of the sleeve 21. That is, the wall of the first cavity 22 facing the second cavity 23 is connected to the wall of the second cavity 23, and the wall of the second cavity 23 facing the third cavity 24 is connected to the wall of the third cavity 24 facing the second cavity 23; or the parts where the first cavity 22 and the second cavity 23 are connected share a part of the wall, and the parts where the second cavity 23 and the third cavity 24 are connected share a part of the wall. Preferably, the first cavity 22, the second cavity 23 and the third cavity 24 are made of silicone material, and are integrally formed with the sleeve 21.

The first pipe 25 extends along the inside or outside of the sleeve 21, and one end thereof passes through the wall of the first chamber 22, so that the inner space of the first pipe 25 communicates with the inner space of the first chamber 22. The first conduit 25 may be separated from the outer wall of the sleeve 21 after passing over or through the third cavity 24, so that the other end of the first conduit 25 becomes a free end. The free end of the first pipe 25 may be provided with an adjusting valve (not shown) for opening and closing the first pipe 25, so as to facilitate the sealing of the first chamber 22 at any time. The first chamber 22 can be inflated or filled with air through the first tube 25 to a desired size.

The second duct 26 also extends along the inside or outside of the sleeve 21, and one end thereof passes through the wall of the second chamber 23, so that the inner space of the second duct 26 communicates with the inner space of the second chamber 23. The second conduit 26 may be separated from the outer wall of the sleeve 21 after passing over or through the third cavity 24, so that the other end of the second conduit 26 becomes a free end. The free end of the second duct 26 may be provided with a regulating valve for opening and closing the second duct 26, facilitating the closing of the second chamber 23 at any time. The physician may inflate or inflate the second lumen 23 with fluid through the second tube 26 to expand the second lumen 23 to the desired size. The second end of the sleeve 21 protrudes 0.5 to 5 cm with respect to the third cavity 24, facilitating the arrangement of the first duct 25 and the second duct 26. In fig. 1 and 2, for convenience of viewing the case where the first duct 25 and the second duct 26 are inside the multi-function member, the first and second duct portions located inside the first to fourth cavities are shown by broken lines.

The third chamber 24 is generally located outside the patient's body, so that one end of the third conduit 27 can be directly connected to the outer wall of the third chamber 24, so that the inner space of the third conduit 27 communicates with the inner space of the third chamber 24. The third duct 27 may extend toward the outside of the multifunctional member 20. Similarly, the free end of the third conduit 27 is also provided with a regulating valve for opening and closing the third conduit 27. The physician may inflate or inflate the third lumen 24 with fluid through the third conduit 27 to expand the third lumen 24 to the desired size.

The preferred first, second and third conduits 25, 26, 27 are integrally formed with the first, second and third cavities 22, 23, 24 and the sleeve 21.

In this embodiment, the first cavity 22 is substantially truncated cone-shaped (substantially trapezoidal when viewed from a direction perpendicular to the outer circumferential surface of the sleeve 21) when expanded to a predetermined size, and has a side wall that is outwardly flared in a circular arc shape, and an end of the largest outer diameter is close to the first end 211 of the sleeve 21, and an end of the smallest outer diameter is connected to the second cavity 23. The shape can ensure that the first cavity 22 can fix the multifunctional part 20 and the anal canal 10 after expansion, so that the multifunctional part is not easy to fall off; when the compression hemostasis function of the end of the rectum is required to be realized, the rectum can be expanded to a preset size according to the requirement, so that a good compression hemostasis function is realized; the function of rectum end expansion can be realized after partial or whole rectum operation is cut. The length of the projection of the first cavity 22 on the cannula 21 (i.e. the dimension extending along the cannula 21) may be 1.5 to 2.0 cm.

The third cavity 24 is generally spherical or football shaped when expanded to a predetermined size. This shape allows the third cavity 24 to assist the first cavity 22 in securing the multifunctional member 20 and the anal canal 10 after expansion, so that the multifunctional member 20 and the anal canal 10 do not slide into the body; and the shape makes the patient more comfortable when taking exercise after the operation.

The second cavity 23 is generally cylindrical when expanded to a predetermined size. Preferably, in consideration of the deformation after expansion, the outer diameter of the second cavity 23 tends to decrease from the two ends to the middle, so that the middle section 231 of the second cavity 23 is concave at the opposite ends in the non-expanded state. So, when needs realize human anal canal hemostasis by compression or expand the anus function, control second cavity 23 expand to the size that needs can, when not needing second cavity 23 to realize hemostasis by compression function, put down gas or liquid in the second cavity 23 can. Namely: if the medical multifunctional self-fixing anal canal plays a role in supporting and draining, the second cavity 23 can not expand; if the compression hemostasis or stenosis expansion function is taken, the anal canal 10 can be not used. In addition, the second cavity 23 can also assist the first and third cavities 24 to achieve a fixing effect after being expanded, so as to prevent the multifunctional member 20 from being displaced. The length of the projection of the second cavity 23 onto the cannula 21 (i.e. the dimension extending along the cannula 21) may be 1.8 to 2.2 cm.

In order to ensure the function of compression hemostasis and the comfort of the patient, the outer surfaces of the part of the second cavity 23 connected with the first cavity 22 and the part of the second cavity 23 connected with the third cavity 24 are smoothly transited.

Furthermore, the second end 212 of the sleeve 21 protrudes 0.5 to 5 cm relative to the third cavity 24, facilitating the arrangement of the first and second ducts 25, 26 and the connection to the anal canal 10. While the first end 211 of the sleeve 21 does not protrude or protrudes only by less than a centimeter with respect to the first cavity 22. In this embodiment, the sleeve 21 near its second end 212 is formed with a hole or groove 213 as a snap feature for receiving the protrusion 14 of the anal canal 10. The hole or groove 213 cooperates with the protrusion 14 to detachably connect the anal canal 10 and the sleeve 21. After the anal canal 10 is connected with the sleeve 21 through the buckling part, the part of the anal canal 10 with the drainage hole 13 extends out of the first end 211 of the sleeve 21 to realize the drainage and support functions, and the second end 12 of the anal canal 10 extends out of the second end 212 of the sleeve 21 to be convenient for connecting parts such as a drainage bag.

Preferably, the sleeve 21 is provided with a plurality of holes or grooves 213 from the second end 212 towards the first end 211, so that the anal canal 10 can be adjusted in length by connecting the protrusions 14 with different holes or grooves 213. Thus, the anal canal 10 can be placed in a relatively high rectum and has supporting and drainage functions for a relatively high intestinal anastomotic stoma (e.g., an intestinal anastomotic stoma that is 15 cm from the human anal canal).

It will be appreciated that other snap features may be used in place of the protrusion 14 and the aperture or slot 213 in other embodiments.

It will be appreciated that the silicone thickness of the sleeve 21 is set so that it can normally maintain the tubular shape, and the wall thicknesses of the first through third cavities 22 through 24 are preferably such that they do not easily maintain their shapes or easily deform them when not expanded, so that the multifunctional member 20 can smoothly enter the human body.

It is understood that the above-described multifunctional member 20 may be used alone.

Please refer to fig. 2, which is a schematic structural diagram of a medical multifunctional self-fixing anal canal according to the second embodiment. The multifunctional self-fixing anal canal of this embodiment is similar to the first embodiment in structure, and the only difference is that the middle section 231 ' of the second cavity 23 ' of the multifunctional member 20 ' is formed with a fold 232 ' that can stretch out when the second cavity 23 ' expands to a predetermined size. These corrugations 232 'extend in generally the same direction as the sleeve 21'. Preferably, when the fold 232 ' is stretched, the second cavity 23 ' has a substantially cylindrical shape, and when the second cavity 23 ' is further expanded, the middle section 231 ' of the second cavity 23 ' may protrude from the opposite ends, so as to achieve compression hemostasis or anal dilatation functions in different degrees as required. When the second cavity 23 'is not needed to be expanded, the anus of the patient can be adapted to the periphery of the second cavity 23' more easily, and the use comfort is improved.

It is to be understood that "substantially" is used herein to describe the situation where substantially the same or slightly different from substantially the same, but generally the situation is observed by a human being to be considered as having no difference from substantially the same or a difference as small as being negligible. For example, the circular truncated cone shape may be regarded as a circular truncated cone shape when viewed by a person, although the circular arc of the outer sidewall of the first cavity 22 is not ideal or the upper side surface is not flat enough after the first cavity is expanded.

In the description of the present invention, it is to be understood that the terms such as "upper", "lower", and the like, which indicate the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
