Teknisk områdeTechnical area

Den foreliggende opfindelse angår en kirurgisk indretning til ombinding af mavesækken på en patient, som vil have gavn af en sådan 5 ombinding, fortrinsvis til nedsættelse af fødeindtagelsen.The present invention relates to a surgical device for binding the stomach to a patient who will benefit from such wrapping, preferably for reducing food intake.

Et formål med opfindelsen er at frembringe en ombinding af mavesækken, hvilken ombinding kan modificeres uden et fornyet kirurgisk indgreb.It is an object of the invention to provide an abdominal wrap which can be modified without a re-surgical procedure.

1010

Teknikkens standpunktThe prior art

Ved en fremgangsmåde, som for tiden er i brug ved behandling af patienter, som lider af obesi, omsnøres mavesækken ved hjælp af et 15 bånd eller lignende, som under det kirurgiske indgreb har en forud fastlagt omkreds. Det har imidlertid vist sig, at omsnøringen i mange tilfælde er enten for stor eller for lille. Dette har ført til fornyede indgreb i næsten halvdelen af tilfældene.In a method currently in use in treating patients suffering from obesity, the stomach is laced with a band or the like, which has a predetermined circumference during the surgical procedure. However, it has been found that the lacing is in many cases either too big or too small. This has led to renewed intervention in almost half of the cases.

20 Beskrivelse af opfindelsenDescription of the Invention

Ved den foreliggende opfindelse tilvejebringes en kirurgisk indretning til ombinding af en patients mavesæk, hvilken indretning omfatter et bånd, som er indrettet til at blive forbundet med sig 25 selv i en ring omkring mavesækken. Indretningen ifølge opfindelsen er ejendommelig ved, at båndet har et hulrum, der er fyldt med et medium, hvilket hulrum har en fleksibel væg, som ved anbringelsen er indrettet til at blive vendt mod mavesækken, i hvilket hulrum mængden af medium kan forøges eller formindskes via en ledning, som 30 er forbundet med hulrummet og udmundende i en injektionsåbning, der er indrettet til at blive placeret under patientens hud, hvorved der kan opnås en forøgelse eller en formindskelse af det frie tværsnitsareal, som begrænses af ringen. Med indretningen ifølge opfindelsen kan båndet, som er udfyldt med en forudbestemt mængde af 35 medium i hulrummet, placeres omkring mavesækken, hvorved den tilsigtede omsnøring af mavesækken opnås. Hvis omsnøringen på et senere tidspunkt viser sig at være for snæver eller for stor, kan den udvides eller indsnævres i ønsket omfang ved indsætning af en injektionsnål gennem huden på patienten ind i injektionsåbningen til DK 168189 B1 2 udtagning eller injektion af medium.In the present invention there is provided a surgical device for binding a patient's stomach which comprises a band adapted to be connected to itself 25 in a ring around the stomach. The device according to the invention is characterized in that the band has a cavity filled with a medium, which cavity has a flexible wall which, upon application, is arranged to face the stomach, in which cavity the amount of medium can be increased or decreased via a conduit connected to the cavity and opening into an injection opening adapted to be placed under the patient's skin, thereby obtaining an increase or decrease of the free cross-sectional area constrained by the ring. With the device according to the invention, the band, which is filled with a predetermined amount of medium in the cavity, can be placed around the stomach, thereby obtaining the intended lining of the stomach. If, at a later stage, the lacing turns out to be too narrow or too large, it can be expanded or narrowed to the desired extent by inserting an injection needle through the patient's skin into the injection opening for DK 168189 B1 withdrawal or injection of medium.

Ifølge en foretrukken udførelsesform for opfindelsen strækker hulrummet sig over en omkring midten af båndet beliggende del, idet 5 båndet har frie ender, som er indrettet til at blive forbundet med hinanden. Sammenføjningen kan fortrinsvis ske ved at lægge de frie båndender over hinanden og sammenføje dem ved hjælp af sutur. Til dette formål kan båndet have en armering, f.eks. en netarmering, som forhindrer suturen i at rive båndet i stykker.According to a preferred embodiment of the invention, the cavity extends over a portion located around the center of the belt, the belt having free ends which are arranged to be connected to one another. The joining can preferably be done by laying the free strap ends over one another and joining them by suture. For this purpose, the belt may have a reinforcement, e.g. a mesh reinforcement that prevents the suture from tearing the tape apart.

1010

Det foretrækkes, at båndet er forsynet med et antal fastgørelses-øjer, som er indrettet til suturering til patientens kropsvæv, fortrinsvis til mavesækkens ydre væg.It is preferred that the band be provided with a plurality of attachment eyes adapted for suturing to the patient's body tissue, preferably to the outer wall of the stomach.

15 Mediet i indretningen kan være en gas, men er fortrinsvis en væske.The medium in the device may be a gas, but is preferably a liquid.

I valget af væske må der tages hensyn til, at den ikke i væsentlig grad må kunne penetrere vægmaterialet, som danner hulrummet, ledningen eller injektionsåbningen. Endvidere må der tages hensyn til, at væsken skal være fysiologisk uskadelig i det tilfælde, at 20 den trods alt skulle lække ud i organismen, f.eks. på grund af beskadigelse af indretningen, uhensigtsmæssig håndtering eller fejl i materialet. Osmotisk aktive eller inaktive væsker kan derfor anvendes. En foretrukken væske er en olie, såsom jordnøddeolie, sojaolie, en anden vegetabilsk olie eller en paraffinolie. Andre 25 foretrukne væsker er vand, en dextranopløsning eller en natrium-chloridopløsning. Væsken kan om nødvendigt indeholde bakteriostatisk virkende stoffer.In the choice of fluid, it must be taken into account that it must not be able to substantially penetrate the wall material forming the cavity, conduit or injection opening. Furthermore, it must be taken into account that the liquid must be physiologically harmless in the event that it should leak into the organism, e.g. due to device damage, improper handling or material failure. Therefore, osmotically active or inactive liquids can be used. A preferred liquid is an oil such as peanut oil, soybean oil, another vegetable oil or a paraffin oil. Other preferred liquids are water, a dextran solution, or a sodium chloride solution. The liquid may contain bacteriostatic agents if necessary.

Injektionsporten kan indrettes på en i og for sig kendt måde, men 30 består fortrinsvis af et bægerformet legeme, i hvis indre ledningen til mediet udmunder, hvilket legeme er indstøbt i et blødt materiale, som er gennemtrænge!igt for en injektionsnål.The injection port can be arranged in a manner known per se, but preferably 30 consists of a cup-shaped body, the inner conduit of which opens to the medium, which body is embedded in a soft material permeable to an injection needle.

Opfindelsen skal beskrives nærmere under henvisning til tegningen, 35 hvor fig. 1 er en afbildning fra siden af en indretning ifølge opfindelsen, 3 DK 168189 B1 fig. 2 er en afbildning i en lille vinkel af båndet til indretningen ifølge fig. 1, og fig. 3 er en skitse, som skematisk viser indretningen ifølge 5 opfindelsen placeret omkring mavesækken.The invention will be described in more detail with reference to the drawing, in which fig. 1 is a side elevational view of a device according to the invention; FIG. 2 is a small angle view of the tape of the device of FIG. 1, and FIG. 3 is a sketch showing schematically the device according to the invention located around the stomach.

Indretningen 1 ifølge opfindelsen omfater et bånd 2, som på den ene side har et hulrum 3 udfyldt med en væske, hvilket hulrum har en fleksibel væg 4. Hulrummet er i forbindelse med en ledning 5 for et 10 medium, hvilken ledning udmunder i en injektionsåbning 6. Ledningen kan overskæres af en kirurg og forbindes i en længde, som er hensigtsmæssig for den enkelte patient, og er til dette formål forsynet med et ikke vist forbindelsesrør.The device 1 according to the invention comprises a band 2 which, on one side, has a cavity 3 filled with a liquid, which cavity has a flexible wall 4. The cavity is in conjunction with a conduit 5 for a medium, which conduit opens into an injection opening. 6. The cord may be cut by a surgeon and connected to a length suitable for the individual patient and provided for this purpose with a connecting tube not shown.

15 Båndet 2 omfatter en bærestrimmel 7 af et materiale, som har en så stor bøjelighed, at det kan sammenføjes til en ring, og som ikke fremkalder trauma på vævsdele, som det bringes i kontakt med. Bærestrimlen indbefatter en netarmering 8. Hulrummet 3 består ifølge fig. 1 og 2 af et rørstykke, der er lukket ved begge ender og som er 20 limet til bærestrimlen. Alternativt kan bærestrimlen udgøre en af hulrummets vægge. Den anden væg 4 omkring hulrummet er beregnet til at blive vendt mod mavesækken ved anbringelsen og er fremstillet af et blødt bøjeligt materiale, som er i stand til at ekspandere ved udfyldning med et medium. Væggen 4 kan alternativt fremstilles af et 25 elastisk materiale.The tape 2 comprises a carrier strip 7 of a material which is so flexible that it can be joined to a ring and which does not cause trauma to tissue parts with which it is brought into contact. The carrier strip includes a net reinforcement 8. The cavity 3 consists of FIG. 1 and 2 of a piece of pipe closed at both ends and glued to the carrier strip. Alternatively, the carrier strip may form one of the cavity walls. The second wall 4 around the cavity is intended to face the stomach during application and is made of a soft, flexible material capable of expanding by filling with a medium. Alternatively, the wall 4 may be made of a resilient material.

Injektionsåbningen 5 omfatter et bægerformet legeme 9, som antydet med punkterede linier på fig. 1, og er indstøbt i et dæksel 10 bestående af blødt materiale.The injection port 5 comprises a cup-shaped body 9, as indicated by dashed lines in FIG. 1, and is embedded in a cover 10 made of soft material.

30 I fig. 2 viser en pil, hvorledes en væske kan indføres via ledningen 5 for mediet i hulrummet, som er vist i delvis ekspanderet tilstand.In FIG. 2 shows an arrow on how a liquid can be introduced via the conduit 5 of the medium into the cavity shown in the partially expanded state.

I fig. 3 er mavesækken betegnet 11, og båndet er forbundet som en 35 ring betegnet ved 12.In FIG. 3, the stomach is designated 11 and the belt is connected as a ring 12 at 12.

Fortrinsvis udgør længden af båndet mellem 60 og 200 mm, hvorved hulrummet optager mellem 40 og 170 mm, og bredden mellem 5 og 20 mm. Væskemængden i hulrummet i fuldstændig ekspanderet tilstand kan 4 DK 168189 B1 passende være mellem 2 og 20 ml. Ved valget af disse parametre, materialet og godstykkelsen kan det frie tværsnitsareal, som er omgivet af båndet i ringform, formindskes med ca. 80% i forhold til det største areal, som er på mellem 150 og 2500 mm2 5Preferably, the length of the tape is between 60 and 200 mm, whereby the cavity occupies between 40 and 170 mm and the width between 5 and 20 mm. Suitably, the amount of liquid in the completely expanded state can be between 2 and 20 ml. By choosing these parameters, the material and the thickness, the free cross-sectional area, which is surrounded by the band in annular form, can be reduced by approx. 80% in relation to the largest area, which is between 150 and 2500 mm2 5

Materialet i indretningen skal være fysiologisk uskadeligt og ikke irriterende for vævet i alle dele, som bringes i kontakt med kropsvæv. Båndet, hulrummets vægge, ledningen og den ydre del af injektionsåbningen kan passende fremstilles af siliconegummi, medens 10 den bægerformede del af injektionsåbningen hensigtsmæssigt kan fremstilles af højtrykspolyethylen eller polyamid.The material of the device must be physiologically harmless and not irritating to the tissue in all parts which are brought into contact with body tissue. The band, cavity walls, conduit, and outer portion of the injection opening may conveniently be made of silicone rubber, while the cup-shaped portion of the injection opening may conveniently be made of high-pressure polyethylene or polyamide.
