Definitions

  • the present invention is generally applicable to the technical field of the surgical devices, and particularly relates to a prosthetic device intended for use in colostomy operations.
  • the invention also relates to a feces collection container usable with the aforesaid device and a colostomy assembly comprising the prosthetic device and the collection container.
  • the colostomy surgical technique allows deviating a portion of the intestinal tube outside the body of the patient, both in a definitive and temporary manner.
  • cutaneous colostomy provides for the passage of a colonic loop through the thickness of the abdominal wall of the patent.
  • the stable fixing of the colonic loop to the body of the patient occurs by suturing the externally-directed end of the loop itself with the skin of the abdomen.
  • a collection container can be removably connected to the end of the colonic loop in order to allow the collection and subsequent evacuation of the feces coming from the intestinal tube.
  • One drawback of such solution is represented by the fact that such technique produces a high percentage of cases (about 60%) in which medical complications arise after colostomy, which make patient tolerability difficult.
  • the skin of the abdomen placed close to the end of the colonic loop can come into contact with the fecal material expelled during the evacuation phase.
  • a device for colostomy is known from US4265244, illustrated in Fig. 1 , having an adaptor A of substantially tubular form with a first end portion P-i intended to come into contact with the skin D of the patient in order to be connected to a feces collection bag.
  • the adaptor A also comprises a second end portion P 2 that is substantially tubular and intended to be inserted inside the abdominal incision B.
  • the termination of the colonic loop C to be colostomized is made to slide outside the external surface S of the adaptor A in a manner such that the same comes into contact with the fecal material during evacuation.
  • the adaptor A is configured for fixing the colonic loop C to the abdominal skin D in a manner such that its external end surface S is interposed between the loop C itself and the skin D, preventing their contact during the evacuation of the fecal material.
  • the object of the present invention is to remedy the abovementioned drawbacks, by providing a prosthetic device for colostomy which is characterized by high efficiency and relatively reduced cost.
  • One particular object is to obtain a prosthetic device for colostomy which does not require the fixing to the abdominal skin of the patient, avoiding the risk of skin diseases such as dermatitis or the like.
  • One particular object is to obtain a prosthetic device for colostomy that allows preventing the feces material from coming into contact with the abdominal skin during the intestinal expulsion step.
  • a further object is to obtain a prosthetic device for colostomy which allows a high bacterial isolation between the device portion intended to be in contact with the feces and the device portion in contact with the abdominal wall, preventing the onset of medical complications or diseases such as dermatitis, stenosis, prolapses and parastomal hernias.
  • Yet another object is to obtain a feces collection container that can be easily coupled to the prosthetic device.
  • a prosthetic device for colostomy in accordance with claim 1 , comprising a tubular connector suitable for being connected to a feces collection container, said connector having an annular end edge intended to be placed in contact with the patient's abdomen close to an abdominal incision.
  • the prosthetic device is characterized in that it comprises a tubular connection member coaxially anchored to said connector close to said annular end edge, said connection member having a substantially cylindrical wall insertable in the abdominal incision with a first support zone for a first suture of connection to a section of the intestinal tube and a second support zone for a second suture of connection to the abdominal incision. Thanks to this particular configuration, it will be possible to secure the device to the body of the patient without it being necessary to suture it to the skin, thus obtaining a colostomy of prosthetic, non-cutaneous type which will allow considerably reducing the onset of medical complications such as dermatitis or the like.
  • a feces collection container is provided, in accordance with claim 12, connectable to the aforesaid prosthetic device.
  • an assembly for colostomy in accordance with claim 15, comprising at least one feces collection container and at least one prosthetic device according to the finding.
  • Advantageous embodiments of the finding are obtained in accordance with the dependent claims.
  • FIG. 1 is a side view in section of a device for colostomy according to the prior art
  • FIG. 2 is a partially sectioned perspective view of a prosthetic device for colostomy according to the finding in a first preferred configuration
  • FIG. 3 is a perspective view in section of the device of FIG. 2;
  • FIG. 4 is a view in section of the device of Fig. 2 applied to a patient
  • FIG. 5 is a view in section of a prosthetic device for colostomy in a second preferred configuration
  • FIG. 6 is a view in section of a prosthetic device for colostomy in a third preferred configuration
  • FIG. 7 represents an application sequence of the device of Fig. 6;
  • FIG. 8 is a partially sectioned side view of a container according to the finding.
  • the prosthetic device for colostomy will be intended for use in both temporary and permanent colostomy surgery operations.
  • an abdominal incision B is made in the abdomen H of a patient in order to deviate a section C of the intestinal tube outside the body, in a manner so as to allow the evacuation of the feces.
  • the prosthetic device 1 for colostomy operations comprises a tubular connector 2 suitable for being connected to a feces collection container 3, illustrated in Fig. 8, and having an annular end edge 4 designed to be placed in contact with the abdomen H of the patient close to an abdominal incision B.
  • the connector 2 is coaxially anchored to a tubular connection member 5 in proximity to its annular end edge 4.
  • connection member 5 has a substantially cylindrical wall 6 insertable in the abdominal incision B, having a first support zone 7 of a first suture W-i for connection to a section C of the intestinal tube and a second support zone 8 of a second suture W 2 for connection to the abdominal incision B.
  • the tubular connector 2 will preferably be made of any polymer material, even rubber or silicon material, suitable for coming into contact with the human body, and possibly but not necessarily suitable for being sterilized in autoclaves and/or under cold conditions.
  • its annular end edge 4 will be substantially flat, in order to come into contact with the skin D by means of simple abutment.
  • the connector 2 will be substantially rigid or semi-rigid in order to be easily handled by an operator, with an internal peripheral surface 9 that is substantially cylindrical and delimiting a central passage 10.
  • the tubular connection member 5 will preferably be flexible, so that it can be easily inserted inside the abdominal incision B and in order to be fixed by means of the sutures W-i and W 2 to the anatomical parts of the patient.
  • connection member 5 can have a net, mesh or even porous structure in order to enhance the contact between the abdominal wall H and the derived intestinal tube section C, in a manner so as to promote the growth of biological tissues when the device 1 must be used in a permanent or in any case prolonged form.
  • the tubular connection member 5 will have axial length l-i greater than that l 2 of the connector 2, in a manner so as to project below the same.
  • the anchoring between the connector 2 and the connection member 5 will be obtained at an annular intermediate portion 12 of the latter, close to its upper edge 11.
  • the upper edge 11 will be radially free with respect to the internal peripheral surface 9 of the connector 2 in order to be handled by the operator and allow the application of the first suture W-i for connection to the intestinal tube section C.
  • the free end of the intestinal tube section C can be bent on the upper edge 11 of the connection member 5, which will define the first support zone 7, and fixed to the same by means of the suture W-i .
  • the intestinal tube section C will always remain contained inside the connector 2, preventing its contact with the outside.
  • the second suture zone 8 can instead be defined by a second annular portion arranged below the anchorage portion 12; such second annular portion can also be suitably shaped, e.g. convex, in order to facilitate the application of the second suture W 2 .
  • connection member 5 can have substantially constant thickness along its entire axial extension with possible localized increases, particularly at the annular intermediate portion 12, so as to compensate for possible thickness reductions due to the anchorage and to provide the correct amount of material for promoting the new growth of intestinal tube biological tissue.
  • anchoring between the connection member 5 and the connector 2 can be carried out above the annular portion 12 with increased thickness.
  • This latter portion will possibly project downward with respect to the end edge 4 of the connector 2 and will have a substantially radial upper surface 13 projecting inward in order to define the first support zone 7 for the first suture W,.
  • connection member 5 and the connector 2 will be obtained at the upper tubular portion 14 of the former, possibly but not necessarily with its upper end edge 11 also in this case not bound to the internal peripheral surface 9 of the connector 2, so as to be free.
  • connection member 5 In another embodiment, illustrated in Fig. 5, the upper tubular portion 14 of the connection member 5 will instead be embedded in the material of the connector 2.
  • the upper tubular portion 14 of the connection member 5 will be made of a first base material that is biologically non-absorbable, but in any case suitable for coming in contact with the human body, in order to mutually isolate the first suture zone 7 from the connector 2.
  • connection member 5 In this manner, growth of intestinal tube biological tissues also on this portion of connection member 5 will be avoided, preventing the fecal bacteria from moving to the connector 2, from here to the abdomen H and subsequently inside the patient's body.
  • connection member 5 will instead be made of a third biologically absorbable material in order to allow the contact between the abdominal wall H and the derived intestinal tube section C and to enhance biological tissue growth.
  • the second material can be selected from among polymer materials, such as polypropylene or the like.
  • annular isolation sleeve 16 can be provided that is made of a second biologically non-absorbable material, possibly equivalent to the first material; such sleeve is fixed inside the connector 2, coaxially superimposed on the upper portion 14 of the connection member s.
  • Fig. 7 illustrates an operative sequence of coupling via suture of the derived intestinal tube section C with the connection member 5. Such sequence, even if referred to the configuration of Fig. 6, can also be applied to the device 1 of Figs. 4 and 5.
  • the latter will be configured so as to cross through both the annular intermediate portion 12 with increased thickness of the connection member 5 and the intestinal section C, before being closed on the radial surface 13 of the former.
  • connection member 5 on an internal or preferably external peripheral surface thereof, can have a graduated scale (not shown in the futures) in order to allow the possible reduction of its axial length l-i, so as to adapt it to the thickness of the abdominal incision B of the patient subjected to colostomy.
  • tubular connector 2 will have a threaded surface 17, e.g. the external peripheral surface thereof, for its removable coupling via screwing with a counter-threaded portion 18 of a collection container 3.
  • Fig. 8 illustrates a container 3 for the feces collection that can be coupled to the prosthetic device 1.
  • the container 3 comprises a containment chamber 20 for the feces having an opening 21 for the passage of the feces and means 22 for the removable anchoring of the chamber 20 to the tubular connector 2 of the prosthetic device 1.
  • the anchorage means 22 will comprise the aforesaid counter-threaded portion 18 of the internal surface 23 of the chamber 20 arranged near its opening 21 in order to allow the coupling by means of screwing to the threaded surface 17 of the tubular connector 2.
  • anchorage means 22 could be configured differently, e.g. as a snap-on bayonet or as a simple male and female coupling, also as a function of the connector configuration 2.
  • the collection chamber 20 can also have suitable valve means (not shown) which are adapted to allow the controlled outflow of intestinal gases present therein.
