Disposable implement inserted into an endoscope
A disposable implement insertable into an endoscope and comprising at least one zone matched to the shape of the endoscope. The at least one zone is designed to be permanently deformed on account of having been used a first time by the inevitable mechanical, thermal and/or chemical treatment it undergoes in the endoscope, and before renewed use in the endoscope. Deformation of the at least one zone eliminates shape-matching of the zone to the endoscope, and is readily visually apparent to a user.
1. A disposable implement for insertion into an endoscope and comprising at least one zone matched to a shape of the endoscope, said implement being initially inserted into the endoscope with a first force prior to a first use of said implement in the endoscope and wherein the zone ( 17 , 24 ) is adapted to become permanently deformed subsequent to the first use and before a second use of the implement in the endoscope ( 10 , 20 ,), said implement being permanently deformed by a treatment selected from the group consisting of mechanical, thermal and chemical treatments, such that shape matching of the implement to the endoscope is permanently eliminated, said implement, following said treatment and despite said permanent deformation, may be reinserted into the endoscope with a second force and used within said endoscope, wherein said second force is substantially greater than said first force and thereby alerts a user to the second use of the implement in the endoscope.
2. The disposable implement as claimed in claim 1 , wherein deformation of the implement results in a clearly visible change in said at least one zone ( 13 , 24 ).
3. The disposable implement as claimed in claim 1 , wherein deformation of the zone ( 24 ) is accomplished by a thermal treatment.
4. The disposable implement as claimed in claim 1 , wherein the deformation of the zone ( 13 ) takes place while the disposable implement ( 12 ) is being removed from the endoscope ( 10 ).
5. The disposable implement as claimed in claim 1 , wherein, after deformation of the zone and re-insertion of the implement into the endoscope, basic functions of the implement are preserved in a manner safe for the patient.
6. The disposable implement as claimed in claim 2 , wherein deformation of the zone ( 24 ) is accomplished by a thermal treatment.
7. The disposable implement as claimed in claim 2 , wherein the deformation of the zone ( 13 ) takes place while the disposable implement ( 12 ) is being removed from the endoscope ( 10 ).
8. The disposable implement as claimed in claim 2 , wherein, after deformation of the zone and reinsertion of the implement into the endoscope, basic functions of the implement are preserved in a manner safe for the patient.
9. The disposable implement as claimed in claim 3 , wherein, after deformation of the zone and reinsertion of the implement into the endoscope, basic functions of the implement are preserved in a manner safe for the patient.
10. The disposable implement as claimed in claim 4 , wherein, after deformation of the zone and reinsertion of the implement into the endoscope, basic functions of the implement are preserved in a manner safe for the patient.
