Abstract
Description
449 450 2 En relativt enkel operationsmetod, s k "gastric banding" har introducerats på senare år (Bo & Modalsli 1983). Den innebär att man fäster en slinga, vanligen formad av en kärlprotes eller nät (t ex Marlex), runt magsäckens övre del, så att en lagom stor ficka bildas, rymmande ca 50 ml. Åtsnörningen försöker man anpassa så att patien- tens födoämnesintag blir ordentligt nedsatt men ändå tillåter så mycket föda att passera, att patienten så småningom stabiliserar sig på en lägre, förhoppningsvis normal vikt. Operationsmetoden är förhållandevis enkel, men resultaten är mycket varierande och svåra att förutse. Blir öppningen för trång kräks patienten. Blir den för vid, blir viktnedgången otillfredsställande. I båda fallen kan man få operera om patienten. Trots dessa svårigheter är gastric banding idag den vanligaste operations- metoden vid fetma i Skandinavien. 449 450 2 A relatively simple surgical method, so-called "gastric banding", has been introduced in recent years (Bo & Modalsli 1983). It involves attaching a loop, usually formed by a vascular prosthesis or mesh (eg Marlex), around the upper part of the stomach, so that a reasonably large fika is formed, holding about 50 ml. Attempts are made to adjust the constriction so that the patient's food intake is properly reduced, but still allow so much food to pass, that the patient eventually stabilizes at a lower, hopefully normal weight. The operation method is relatively simple, but the results are very varied and difficult to predict. If the opening becomes too narrow, the patient vomits. If it gets too wide, the weight loss will be unsatisfactory. In both cases, you can have surgery on the patient. Despite these difficulties, gastric banding is today the most common surgical method for obesity in Scandinavia.
Operationer på dessa extremt feta patienter innebär avsevärda operationstekniska problem. Åtkomligheten för kirurgiska åtgärder kräver speciellt utformade hakar och instrument. Varje anordning som kan underlätta applikationen av bandet för åtstramning runt mag- säcken och förenkla operationen är därför värdefull. Det är svårt att standardisera vidden av öppningen i magsäcken, likaså den övre mag- säcksfickans volym. Ett nät som sys in är svårt att fixera i rätt läge.Operations on these extremely obese patients involve significant surgical problems. The accessibility of surgical procedures requires specially designed hooks and instruments. Any device that can facilitate the application of the band for tightening around the stomach and simplify the operation is therefore valuable. It is difficult to standardize the width of the opening in the stomach, as well as the volume of the upper stomach. A mesh that is sewn in is difficult to fix in the right position.
Komplikationer i form av dislokation av nätet och skador på magsäcks- väggen med invandring av suturer och infektion i det inplanterade materialet förekommer icke helt sällan. Bindsvävsvandling med icke önskvärd förträngning kan med tiden uppstå. Risken för komplika- tioner med hittillsvarande teknik och material illustreras av bifogad referens (Coelho et al. 1985). Önskvärdheten att åstadkomma en reglerbar anordning för att kunna justera åtsnörningen av magsäcken har länge diskuterats av kirurger intresserade av denna form av kirurgi. Det har legat nära till hands att kombinera nät eller insydd kärlprotes med någon form av ballong ansluten till en inplanterbar infusionsport, t ex av typ PORT-A-CATH, som finns kommersiellt tillgänglig. Någon praktiskt användbar metod tycks ej ha framkommit, sannolikt därför att insyning av ett nät inte är lämpligt att kombinera med en uppblåsbar anordning.Complications in the form of dislocation of the mesh and damage to the stomach wall with immigration of sutures and infection in the implanted material are not uncommon. Connective tissue transformation with undesirable narrowing can occur over time. The risk of complications with prior art and materials is illustrated by the attached reference (Coelho et al. 1985). The desirability of providing an adjustable device to adjust the constriction of the stomach has long been discussed by surgeons interested in this form of surgery. It has been close at hand to combine a mesh or sewn-in vascular prosthesis with some form of balloon connected to an implantable infusion port, for example of the PORT-A-CATH type, which is commercially available. No practically useful method seems to have emerged, probably because the insertion of a net is not suitable to be combined with an inflatable device.
Följande krav bör kunna ställas på en anordning för åtsnörning av magsäcken vid gastric banding: Apglikgtignen skall vara enkel och snabb även hos dessa extremt feta och svåropererade patienter skall vara vävnadsvänligt och steriliserbart Stabil och säker skall finnas. Ringen skall inte fixeras med suturer, som kan glida upp, skära sönder materialet, orsaka vävnadsskada eller med tiden fragmentera._ Suturering med nål innebär också fara för punktering om man avser att ansluta bandet till någon form av uppblåsbar anordning. Om bandet skall an- 3 449 430 vändas utan regleringsanordning bör det finnas i olika storlekar eller vara justerbart och åtdragbart vid operationen.It should be possible to impose the following requirements on a device for constriction of the stomach during gastric banding: The application must be simple and fast, even in these extremely obese and difficult-to-operate patients it must be tissue-friendly and sterilizable. Stable and safe must be available. The ring should not be fixed with sutures, which can slide up, cut the material, cause tissue damage or fragment over time. Suturing with a needle also involves the risk of puncture if you intend to connect the band to some form of inflatable device. If the belt is to be used without a control device, it should be available in different sizes or be adjustable and tightenable during the operation.
Om man avser att kombinera bandet med regleringsanordning tillkommer ytterligare krav: * bör helst vara i samma material som bandet och fast sammanfogat med detta.If you intend to combine the belt with a control device, additional requirements are added: * should preferably be in the same material as the belt and firmly joined to it.
Justeringen skall vara enkel och icke åtkomlig för patienten. _ Ringens vidd skall kunna justeras alltefter patientens viktnedgång utan att patienten själv skall kunna påverka detta.The adjustment should be simple and not accessible to the patient. _ The width of the ring must be adjustable according to the patient's weight loss without the patient being able to influence this.
Lägeskontrgll bör enkelt kunna ske genom t ex injektion av kont- rast i den uppblåsbara delen och ultraljud eller röntgen- i undersökning. i I enlighet med föreliggande uppfinning åstadkommes detta ändamål och dessa fördelar med en protes, vilken kännetecknas av att den omfattar a) ett till en sluten slinga åtdragbart band av varierande vidd an- ordnat att kunna anbringas runt en magsäck, b) en låsanordning for fixering av slingan, c) en bandfórlängning med kapanvisning Bandet kan användas i denna form for att underlätta den vanliga operationsmetod som kallas "gastric banding". Bandet avses att kunna tillverkas i flera olika vidder med inre omkrets från 7 till 12 cm. En viss justerbarhet vid hopfästningen kan åstadkommas beroende på hur hårt bandet åtdrages.It should be possible to easily check the position by, for example, injecting contrast into the inflatable part and ultrasound or X-ray examination. In accordance with the present invention, this object and these advantages are achieved with a prosthesis, which is characterized in that it comprises a) a strap tightening to a closed loop of varying width arranged to be able to be applied around a stomach, b) a locking device for fixing of the loop, c) a band extension with cut instruction The band can be used in this form to facilitate the usual surgical method called "gastric banding". The belt is intended to be manufactured in several different widths with an inner circumference from 7 to 12 cm. Some adjustability in the fastening can be achieved depending on how tight the strap is tightened.
Uppñnningen i detta grundutfórande ger förutsättningen för kombination med en reglerbar anordningi form av d) en på bandets insida fästad krage med variabel volym och e) organ for till eller bortförsel av en vätska till resp från kragens inre för reglering av vätskemängden i kragen och därmed kragens volym.The invention in this basic embodiment provides the precondition for combination with an adjustable device in the form of d) a collar attached to the inside of the belt with variable volume and e) means for adding or removing a liquid to or from the inside of the collar for regulating the amount of liquid in the collar and thus the collar. volume.
Enligt en fóredragen utfóringsform av protesen enligt uppfin- ningen utgöres organen fór till eller bortfórsel av vätskan av en ledning, vars ena ände anslutes till kragen och den andra änden till en s k infusionsport avsedd att inplanteras i bukväggen. Med en injektionsnål kan membranet i infusionsporten punkteras och vätska till eller bort- tagas med hjälp av injektionsspruta.According to a preferred embodiment of the prosthesis according to the invention, the means for conveying or removing the liquid are constituted by a conduit, one end of which is connected to the collar and the other end to a so-called infusion port intended to be implanted in the abdominal wall. With an injection needle, the membrane in the infusion port can be punctured and fluid added or removed using a syringe.
Föredraget material vid tillverkning av protesen är silikongummi, vilket har lämpliga egenskaper fór tillverkning av protesens samtliga komponenter och är ett av de mest vävnadsvänliga material som finns tillgängliga for inplantation. 449 430 q Den vätska som används for reglering av kragens volym är före- trädesvis en vattenhaltig vätska. Enligt en aspekt av uppfinningen inne- håller vätskan ett röntgenkontrastmedel for att möjliggöra lägeskontroll och kontroll av kragens utspänning. Enligt en annan aspekt innehåller vätskan ett bakteriehämmande medel, vilket genom diffusion genom den mikroporösa strukturen i kragens och bandets material kan motverka infektion i protesen.The preferred material in the manufacture of the prosthesis is silicone rubber, which has suitable properties for the manufacture of all components of the prosthesis and is one of the most tissue-friendly materials available for implantation. 449 430 q The liquid used to regulate the volume of the collar is preferably an aqueous liquid. According to one aspect of the invention, the liquid contains an X-ray contrast agent to enable position control and control of the tension of the collar. According to another aspect, the liquid contains a bactericidal agent, which by diffusion through the microporous structure in the material of the collar and band can counteract infection in the prosthesis.
Uppfinningen kommer i det följande att beskrivas närmare under hänvisning till bifogade ritningar, där g fig l visar konstruktionsritning av bandet i grundutfórande fig 2 visar schematiskt protesband enligt fig 1 hopíäst och app- licerad på en magsäck vid gastric banding. fig 3 visar konstruktionsritning av protes med regleringsorgan fig 4 visar schematiskt protes med regleringsorgan enligt fig 3 i hopfast läge och applicerad på magsäck. 5 a 449 430 Beskrivning: Protesbandet omfattar, som bäst framgår av fig 1, ett till en slynga hopfästbart band (1 :1 ), vilket i sin ena ände är försett med en sölja (1 :2) och i andra änden en bandförlängxiing (1:3), vilken är avsedd att avskiljas från den hopfästbara slyngan i kapanvisningen (1 :4) sedan bandförlängningen (1 :3) dragits genom söljan (1:2) och ytterdelen av låsanordningen (lzö) med sina griphack dragits ini söljan med motsvarande hack (1:2). På ritningen har 4 griphack inritats, men bandet kan försesmed ytterligare griphack om man önskar större variabilitet vid åtdragning av bandet.The invention will be described in more detail below with reference to the accompanying drawings, in which g fi g 1 shows a construction drawing of the band in the basic embodiment fi g 2 shows a schematic prosthesis band according to fi g 1 hopiäst and applied to a stomach during gastric banding. fi g 3 shows construction drawing of prosthesis with control means fig. 4 schematically shows prosthesis with control means according to fi g 3 in a fixed position and applied to the stomach. Description of the prosthetic band comprises, as best seen in Fig. 1, a band (1: 1) which can be fastened to a sling, which is provided at one end with a bar (1: 2) and at the other end a band extension ( 1: 3), which is intended to be separated from the fastenable sling in the cutting instruction (1: 4) after the strap extension (1: 3) has been pulled through the column (1: 2) and the outer part of the locking device (lzö) with its gripping notches has been pulled into the column with corresponding notch (1: 2). 4 gripping notches have been drawn in the drawing, but the belt can be provided with additional gripping notches if greater variability is desired when tightening the belt.
Protesbandet avses tillverkas i flera olika längder med omkrets i låst läge mellan 70 och 120 mm. ' Fig 2 visar en schematisk bild av magsäck (2a), det hopfästa bandet efter kapning av bandförlängníngen (2b) samt bandet applicerat på mag- säcken vid gastric banding (2c).The prosthetic band is intended to be manufactured in different lengths with a circumference in the locked position between 70 and 120 mm. Fig. 2 shows a schematic view of the stomach (2a), the fastened band after cutting the band extension (2b) and the band applied to the stomach during gastric banding (2c).
Fig 3 visar protes med regleringsanordning, där en kopplingsför- stärkning (3 :1) markerar var ledningen från infusionsporten skall in- kopplas. Denna ledning skall vara fast förenad med protesen genom lim- ning. Bandförlängningen är försedd med ett hål (3:2) för att underlätta bandets applikation runt magsäcken. Kapanvisningen är markerad (323).Fig. 3 shows a prosthesis with a control device, where a coupling gain (3: 1) marks where the line from the infusion port is to be connected. This cable must be firmly connected to the prosthesis by gluing. The band extension is provided with a hole (3: 2) to facilitate the band's application around the stomach. The cut instruction is highlighted (323).
Mot bandets insida är kragen (3:4) fästad.The collar (3: 4) is attached to the inside of the strap.
Fig 4 visar en schematisk bild av protes med regleringsanordning dels i hopfogat läge (4a), dels applicerad på magsäck (4b). Anden av bandet (4a:1) har dragits genom söljan med låsanordningen (4a:2). På bandets insida ses den expanderbara kragen (4az3). Ledningen (4a:4) för vätska mellan kragen (4a:3) och infusionsporten med membran (4a:5).Fig. 4 shows a schematic view of a prosthesis with an adjusting device partly in the joined position (4a), partly applied to the stomach (4b). The spirit of the strap (4a: 1) has been pulled through the column with the locking device (4a: 2). On the inside of the strap is the expandable collar (4az3). The line (4a: 4) for liquid between the collar (4a: 3) and the infusion port with membrane (4a: 5).
När protesen anbringats på magsäckens övre del bildas en mindre ficka (4b:1) ovanför åtsnörningen. Ledningen (4bz2) har dragits genom bukhinnan (4b:3) och genom den raka bukmuskeln (4bz4) där infusions- porten fixerats med suturer vid muskelns främre bindvävshinna. Vid genomdragning av ledningen genom bukväggsmuskeln är infusions- porten bortkopplad och ledningen, som är 300 mm lång, avkapas till passande längd före anslutningen till infusionsporten. Kopplingsanord- ning mellan ledning och infusionsport finns kommersiellt tillgänglig som tillbehör till infusionporten.When the prosthesis is applied to the upper part of the stomach, a smaller pocket (4b: 1) is formed above the constriction. The lead (4bz2) has been drawn through the peritoneum (4b: 3) and through the straight abdominal muscle (4bz4) where the infusion port fi xerated with sutures at the anterior connective tissue membrane of the muscle. When the line is pulled through the abdominal wall muscle, the infusion port is disconnected and the line, which is 300 mm long, is cut to the appropriate length before connection to the infusion port. Coupling device between line and infusion port is commercially available as an accessory to the infusion port.
Den operativa metoden vid inplantationen av protesen följer i övrigt förfarandet vid s k gastric banding (Bo & Modalsli) men förenklas genom att protesen ej fordrar fixering med suturer och ej heller den noggranna justering av öppningens storlek som vanligen krävs vid denna operations- metod. Operationstiden förkortas uppskattningsvis 20 - 40 minuter.The surgical method of implantation of the prosthesis otherwise follows the procedure of so-called gastric banding (Bo & Modalsli) but is simplified in that the prosthesis does not require fixation with sutures nor the precise adjustment of the size of the opening that is usually required in this surgical method. The operation time is shortened by an estimated 20 - 40 minutes.
