Definitions

  • the invention relates to a medical device for connecting two portions of the intestine, consisting of two coupling components which can be connected with each other, which can be inserted in the respective extremities of the two portions of the intestine, and between which - in the coupled state - these intestinal extremities can be clamped, the said coupling components comprising coupling means which are provided with a projecting pin, which is connected with the first coupling component, which pin fits into a continuous central aperture formed in the second coupling component, and fixing means which keep the second coupling component, in the coupled state, pressed against the first coupling component, while clamping the intervening ends of the intestine.
  • the invention further relates to an ancillary device for use therewith and a method for the insertion of an intestinal button suture with the aid of this device.
  • a medical device is known from US patent 2,434,030.
  • the connection between the two portions of the intestinal button suture can only be made and maintained by manipulation of the portion of one of the components which projects outside the body of the patient.
  • this known design is restricted to rectum/colon anastomosis.
  • this device suffers from the disadvantage that during convalescence the device remains projecting outside the body, so that there is a danger of damage to the portion of the colon which is still vulnerable.
  • the device has to be adjusted and regulated by feel.
  • the invention aims at providing a medical device of the above-mentioned type capable of universal application for all types of intestinal sutures, which is extremely easy to employ, which is extremely light, and which can easily leave the body and furthermore ensures efficient healing of the intestine.
  • the device in accordance with the invention is characterised in that the projecting pin of the first coupling component is made internally hollow, with an internal dimension which is at least 1/3 of the external dimension of the first coupling component, said cavity- traversing the entire coupling component, wherein the pin has a sliding fit in the central aperture in the second coupling component, while the fixing means consist of magnets which are located in the parts of the coupling components, which face each other in the coupled state, adjacent to the projecting pin in the first coupling component and adjacent to the central aperture in the second coupling component, respectively.
  • the cross sectional profile of the coupling components is not an essential item, it is evidently of advantage, both from the manufacturing and the manipulation viewpoints, to make the coupling components rotationally symmetrical. More particularly the manipulation of the two coupling components in the intestinal extremities is rendered easier if both coupling components are rings with a cylindrical external surface and with the same ring diameter.
  • manufacture of the device is simple if the magnets in the coupling components are made ring-shaped with an external diameter equal to or less than the external diameter of the corresponding coupling component, and with an internal diameter larger than the largest pin diameter.
  • the thickness of the ring-shaped magnets does not need to be equal to the axial length of the coupling portions. Since, in order to exert their effect, the magnets must be as close as possible to the end faces of the two ring-shaped coupling components which must face each other, and since only that portion which is located close to the end face contributes essentially to the closure force exerted by the device, the axial length of the coupling components is greater than the thickness of the magnets. To prevent overturning during manipulation, the axial length of the casing of the actual coupling components should preferably be greater than the thickness of the magnets.
  • apertures are recessed in the magnet- -free portion of the cylindrical casing of the coupling components which faces away from the end faces. Furthermore, these apertures contribute towards a reduction in weight, which is important, because pressure due to the weight of the device during convalescence can result in damage (bed sores).
  • the pin and the central aperture are given such a profile that the central aperture of the second coupling component can be pushed over the pin of the first coupling component without rotation around its axis occurring.
  • the external profile cross section of the pin and the internal profile cross section of the central aperture have the form of a regular polygon, especially a hexagon.
  • the hexagon shape has advantages for manufacturing purposes, but it is naturally also possible to employ forms of other polygons or grooves, ribs, etc., although as a rule these are admittedly inefficient by nature.
  • the pin is provided at its end with an outwardly-projecting rim, longitudinal slots being provided in this end, wherein the central aperture in the coupling section at some distance from the end face has a broadend portion, the dimension of which is greater than that of the rim of the pin, while the distance from the projecting rim of the pin to the end face of the first coupling component is 2-6 mm greater than the said distance from the broadened portion of the central aperture to the end face of the second coupling component.
  • the coupling components may be manufactured from any material which is inert in the body and which does not give rise to tissue reactions. However, the coupling components are intended to remain only temporarily in the body and, after healing of the wound (whereby the tissue clamped between the rings dies) the coupling device works loose from the wall of the intestine and is removed by a natural path together with the faeces.
  • a suitable material for the body of the coupling components is an inert plastic material which can be extruded.
  • a suitable plastic material is, for example, a polyester polyethylene terephtjnalate.
  • the magnets should preferably be made from polymer-combined rare earth cobalt alloys, because in the non-magnetised state these materials can be easily machined.
  • the device in accordance with the invention is excellently suit able for making faultless intestinal sutures, whereby above all the danger of post-operative complications is considerably reduced.
  • the device can be employed at all locations in the human body where intestinal resections are required, as in the oesophagus, the thin intestine the thick intestine and the colon.
  • colon/intestine resections are among the most difficult operations, because frequently only a short section is left of the colon which lies deeply concealed in the abdomen. Manipulation is difficult at this point.
  • the invention similarly aims at providing an ancillary device for this type of operation, whereby colon anastomosis can be made easier.
  • this ancillary device in accordance with the invention is characterised by a seating knob, on which the end facing away from the end face of the second coupling component can be placed, a knob which is rounded at its front end and which can be placed on the end face of the second coupling component, wherein the seating knob, the second coupling component and the knob, in the assembled state, form a continuous cylinder and - in the assembled state - can be introduced into a portion of the intestine in the patient's body by means of an insertion pin.
  • the seating knob is screwed onto the insertion pin, wherein subsequently the knob can be attached to the seating knob with the second coupling component between them.
  • This provides a smoothly fashioned entity which is introduced rectally into the stump of the colon by means of the insertion pin until the rounded knob appears at the abdomen side. Then, from externally, the coupling between the rounded knob and the seating knob is loosened and the rounded knob is removed.
  • an extension rod can now be fastened to the seating knob, the said extension rod having the same external profile cross section as the projecting pin of the first coupling component, and one end of which can be inserted in the cavity of the pin, wherein stop means are provided for fixing the precise mutual position of the pin and the extension rod. Then the suture which is arranged around the end of the intestine is tightened until the end of the intestine contacts with the extension rod which now projects upwards into the abdominal cavity.
  • the coupling component By means of the insertion pin the coupling component is now pressed upwards, by means of which it is more easily reached by the operator, who now by hand brings the coupling component with the projecting pin already inserted in the other end of the intestine towards the projecting end of the extension rod, and, in the right position, pushes the projecting pin onto the extension rod. Whilst the operator now, with one hand, holds one end of the intestine and with the other hand holds the other end of the intestine, the surgical assistant slowly pulls the insertion pin with the seating knob fastened thereto and the extension rod fastened thereto downwards and out of the body of the patient, as a result of which the two coupling components approach each other without any mutual twisting being possible. Ultimately only the two coupling components are left behind in the body, with the ends of the intestine clamped between them.
  • the knob can be attached to a first end of the insertion pin, wherein the seating knob forms the front end of a cylindrical sleeve, in which the insertion pin is slidably in such a manner that the insertion pin can be pushed through the central aperture of the coupling component placed on the seating knob.
  • the first end of the insertion pin can be inserted in the cavity of the projecting pin of the first coupling component, wherein a portion of the insertion pin which extends from this end possesses the same external profile cross section as the pin.
  • the first end of the insertion pin portion can be detachably fastenable in the cavity of the projecting pin of the first coupling portion, whereby the coupling of the two coupling components is considerably simplified.
  • the invention also comprises a procedure for provision of an intestinal suture with the aid of a device in accordance with the invention, characterised by the fact that after resection of the intestine the mucosa and the sub-mucosa are separated from the surrounding muscular layer, which is removed over a distance of several millimetre after which the two coupling components are applied in the ends of the intestine and only the mucosa and sub-mucosa layers are clamped between the two coupling components.

  • Fig. ) is a perspective view of the end face of the coupling portions in the non-coupled state.

  • Figs. 19a-19e illustrate an alternative embodiment of the ancillary device in accordance with the invention, together with the use thereof.
  • the medical device shown in figs. 1-3 in accordance with the invention consists of a first coupling component 1 with a projecting pin 2, which is hollow internally, and which fits into a central aperture 3 of a second coupling component 4.

This prevents any twisting of the intestinal suture.
  • Both of the coupling components 1, 4 have a cylindrical casing 13, 14, respectively, having the same ring diameter.
  • the external diameter of the magnets 5-. 6 is less than the external diameter of the coupling components 1 , 4, but if desired can be equal thereto.

  • Apertures 15, 16 are provided in the portion of the cylindrical casing 13, 14 of the coupling components 1, 4 which is free from magnetic material, said apertures 15, 16 having a double purpose. First of all they serve to discharge waste material which can be present between the wall of the intestine and the device, and secondly these apertures 15, 16 provide a desirable saving in weight. For good wound healing it is always of great importance that as little pressure as possible is exerted on the portion of the intestine to be healed. One difficulty with the devices hitherto has been especially their considerable weight, which on numerous occasions has given rise to damage to the intestine as a result of bed sores. By the provision of the later/al apertures 15, 16 the weight of the said devices is reduced, whereby the risk of damage to the intestine has been considerably reduced.
