Opfindelsen angår et kirurgisk instrument til indvortes brug i forbindelse med kirurgiske operationer i legemshulrum og navnlig i forbindelse med operationer i bughulen.The invention relates to a surgical instrument for internal use in connection with surgical operations in body cavities and in particular in connection with abdominal operations.
® Kendt teknik® Known technique
Under bughuleoperationer er det almindeligvis nødvendigt at skubbe mavetarmkanalen tilside for at holde det sted, hvor operationen udføres, fri og let tilgængelig. Det er til dette formål kendt at holde tarmene i en bestemt stilling ved at anvende væskeabsorberende bom- 10 uldsduge og sårhager, som holdes manuelt under operationen af en eller flere sygeplejersker, som assisterer kirurgen.During abdominal operations, it is usually necessary to push the gastrointestinal tract aside to keep the place where the operation is performed free and easily accessible. For this purpose, it is known to hold the intestines in a specific position by using fluid-absorbing cotton cloths and wounds which are held manually during the surgery by one or more nurses assisting the surgeon.
Anvendelsen af sådanne bomuldsduge og sårhager frembyder flere ulemper. Således forhindrer anvendelsen af bomuldsduge ikke, at de tilbageholdte tarme gradvis frigøres og generer kirurgen, idet 1 ζ assistenterne efterhånden bliver trætte af at holde bomuldsdugene og sirhagerne og som følge af, at bomuldsdugene på grund af deres begrænsede væskeabsorptionsevne fra tid til anden skal erstattes af nye bomuldsduge. Udskiftningen af bomuldsdugene sinker ikke alene operationen men kan også medføre, at operationen ikke bliver udført £ pi det mest hensigtsmæssige tidspunkt.The use of such cotton cloths and wounds presents several disadvantages. Thus, the use of cotton cloths does not prevent the intestines from being gradually released and inconveniencing the surgeon, with the 1 ζ assistants gradually getting tired of holding the cotton cloths and the sirens and, due to their limited liquid absorbency, from time to time having to be replaced. new cotton cloths. The replacement of the cotton cloths not only slows down the operation but can also cause the operation not to be performed at the most convenient time.
Ydermere kan anvendelsen af bomuldsduge bevirke, at små partikler, som frigøres herfra, indføres i legemshulrummet, hvorfra de er vanskelige at fjerne.Furthermore, the use of cotton fabrics can cause small particles released from them to be introduced into the body cavity from which they are difficult to remove.
Formålet med opfindelsen er at tilvejebringe et kirurgisk in-strument til brug i legemshulrum og til at holde organerne, såsom tarmene, i en fast stilling under operationen uden bistand af hjælpepersonale og uden at beskadige organerne.The object of the invention is to provide a surgical instrument for use in body cavities and to hold the organs, such as the intestines, in a fixed position during surgery without the assistance of auxiliary personnel and without damaging the organs.
Omtale af opfindelsen ΟΛDisclosure of the Invention ΟΛ
Dette formål opnås med det kirurgiske instrument ifølge opfindelsen, hvilket instrument er ejendommeligt ved, at det har stangform og omfatter et uelastisk deformerbart, let bøjeligt legeme, som er omsluttet af et blødt væskeabsorberende materiale, der eventuelt er indesluttet i et hylster.This object is achieved with the surgical instrument according to the invention, which is characterized in that it has a rod shape and comprises an inelastic deformable, easily bendable body which is enclosed by a soft liquid absorbent material, which is optionally enclosed in a sheath.

Tilstedeværelsen af det uelastisk deformerbare, let bøjelige legeme i instrumentet ifølge opfindelsen bevirker, at det stangformede legeme efter at være blevet passende tildannet til at holde organerne, såsom tarmene, i en given stilling, uændret beholder den herved op- 2 144082 nlede form, hvorved anvendelsen af manuelt fastholdte hjælpemidler bliver overflødig. Da det uelastisk deformerbare legeme er omgivet af det bløde væskeabsorberende materiale vil der ved bøjningen af instrumentet omkring organerne ikke ske en beskadigelse af disse.The presence of the inelastically deformable, easily bendable body in the instrument of the invention causes the rod-shaped body, after being appropriately formed to hold the means, such as the intestines, in a given position, to retain unchanged shape thereby the use of manually held aids becomes unnecessary. Since the inelastically deformable body is surrounded by the soft liquid-absorbing material, the bending of the instrument around the organs will not damage them.
5 Tilstedeværelsen af det væskeabsorberende materiale bevir ker også, at væske, såsom blod, der afgives under operationen, opsamles og derved forhindres i at interferere med operationen.The presence of the liquid-absorbing material also causes liquid, such as blood that is released during the operation, to be collected and thereby prevented from interfering with the operation.
Da tykkelsen af det væskeabsorberende materiale, der omgiver det uelastisk deformerbare legeme, kan varieres uden nogen væ-10 sentlig ugunstig virkning pi bøjeligheden af instrumentet ifølge opfindelsen, kan instrumentets væskeabsorptionsevne varieres indenfor vide grænser og efter behov.Since the thickness of the liquid absorbent material surrounding the inelastic deformable body can be varied without any appreciable adverse effect on the flexibility of the instrument of the invention, the liquid absorbency of the instrument can be varied within wide limits and as required.
En stor væskeabsorptionsevne hos instrumentet ifølge opfindelsen kan være af stor betydning for en operations gunstige forløb.A high fluid absorbency of the instrument of the invention can be of great importance for the favorable course of an operation.
15 I tilfælde, hvor en patient mister blod under operationen, absorberes blodet således i det væskeabsorberende materiale, og den mistede mængde blod kan måles med mellemrum ved at udtage instrumentet fra legemshulrummet og fjerne blodet herfra ved sammenpresning. Ved at bestemme den mængde af blod, der er mistet, kan der foretages en ' 20 nøjagtig dosering af bedøvelsesmidlet, idet doseringen af bedøvelses midlet afhænger af den resterende mængde blod i patienten.Thus, in cases where a patient loses blood during surgery, the blood is absorbed into the fluid-absorbing material and the lost amount of blood can be measured at intervals by withdrawing the instrument from the body cavity and removing the blood from it by compression. By determining the amount of blood lost, an accurate dosage of the anesthetic can be made, the dosage of the anesthetic depending on the remaining amount of blood in the patient.
En foretrukken udførelsesform for instrumentet ifølge opfindelsen omfatter et perforeret, bøjeligt rør, der er indlagt i det væskeabsorberende materiale, og som er således indrettet, at det kan 25 forbindes med et sugeorgan, f.eks. en pumpe, over en væskekollek-tor.A preferred embodiment of the instrument according to the invention comprises a perforated, flexible tube which is embedded in the liquid-absorbing material and which is arranged so that it can be connected to a suction means, e.g. a pump, over a liquid collector.
Ved anvendelse af denne udførelsesform for instrumentet ifølge opfindelsen kan blodet, der absorberes i det væskeabsorberende materiale, kontinuerligt fjernes herfra og opsamles i væskekollektoren, 30 hvorved mængden af mistet blod kontinuerligt kan bestemmes.Using this embodiment of the instrument of the invention, the blood absorbed in the liquid-absorbing material can be continuously removed from it and collected in the liquid collector, whereby the amount of lost blood can be continuously determined.
I beskrivelsen til USA patent nr. 3.923.052 er der omtalt en fenestrationsdrapering omfattende et eller flere stykker uvævet stof og strimler af et uelastisk deformerbart bøjeligt materiale. Formålet med disse strimler er at tilpasse draperingen til legemets form omkring 35 det sted, hvor det kirurgiske indgreb skal finde sted. Den kendte drapering er alene beregnet til udvortes brug og har kun ringe absorptionsevne.In the disclosure of U.S. Patent No. 3,923,052, a fenestration drape comprising one or more pieces of nonwoven fabric and strips of an inelastic deformable flexible material is disclosed. The purpose of these strips is to adapt the drape to the shape of the body at about the place where the surgical procedure is to take place. The known draping is intended for external use only and has little absorbency.
Det uelastisk deformerbare legeme i instrumentet ifølge opfindelsen er fortrinsvis metallisk, f.eks. fremstillet af aluminium. Et 144082 3 metallisk legeme frembyder den særlige fordel, at det kan lokaliseres ved røntgenundersøgelse, såfremt det utilsigtet er blevet efterladt i et legemshulrum.The inelastic deformable body of the instrument according to the invention is preferably metallic, e.g. made of aluminum. A metallic body offers the special advantage that it can be located by x-ray examination if it has been unintentionally left in a body cavity.
Formen af det uelastisk deformerbare legeme er ikke kritisk, 5 men legemet har fortrinsvis form som en strimmel.The shape of the inelastically deformable body is not critical, but the body preferably has the shape of a strip.
Det skal underforstås, at det uelastisk deformerbare legeme kan være et leddelt legeme forudsat, at ledforbindelserne er udført på en sådan måde, at legemet opretholder sin form efter at være blevet deformeret.It is to be understood that the inelastic deformable body may be an articulated body provided that the articulated joints are made in such a way that the body maintains its shape after being deformed.
10 Det væskeabsorberende materiale består fortrinsvis af blødt formstofskum, f.eks. polyetherskum. Ved anvendelse af blødt poly-etherskum kan væske, der er absorberet heri, let fjernes ved sammenpresning, og instrumentet kan påny anvendes ved samme operation.The liquid-absorbing material preferably consists of soft plastic foam, e.g. polyether foam. Using soft polyether foam, liquid absorbed herein can be easily removed by compression and the instrument can be reused in the same operation.
15 Også andre væskeabsorberende materialer, f.eks. bomulds vat og lignende materialer, er anvendelige. I tilfælde, hvor det væskeabsorberende materiale er bomuldsvat, foretrækkes det at anvende et hylster, f.eks. et hylster fremstillet af et fnugfrit formstofmateria-le. Hylsteret kan være rørformet og kan være vævet eller strikket.Other liquid absorbing materials, e.g. cotton wool and similar materials are useful. In cases where the liquid-absorbing material is cotton wool, it is preferred to use a sheath, e.g. a casing made of a lint-free plastic material. The casing may be tubular and may be woven or knitted.
20 Det er fortrinsvis fremstillet ud fra et formstofmateriale, f.eks. ud fra nylontråd.It is preferably made from a plastics material, e.g. based on nylon thread.
Det rørformede hylster kan være lukket ved enderne ved kendte metoder, f.eks. ved sammenbinding, sammenlimning, sammensyning eller forsegling.The tubular sleeve may be closed at the ends by known methods, e.g. by bonding, bonding, sewing or sealing.
