Definitions
- the present invention relates to forceps for medical use, in particular for biopsy, for example, for endoscopic biopsy, laparoscopy, gynaeocological applications and the like.
- a conventional forceps of this type comprises two half-shells, each of which has a front rim and a base wall, and which are mounted on a support element in a manner such that they can adopt a first, opened-out configuration and a second, closed configuration.
- the forceps is passed through the operating duct of an endoscope in the closed configuration and is brought into contact with the internal mucosa of the organ (for example, the oesophagus, stomach, duodenum, or colon) to be biopsied.
- the organ for example, the oesophagus, stomach, duodenum, or colon
- the half-shells are opened and then closed so as to cut off a sample of the mucosa which remains held between them. Given the intrinsically limited nature of the space available, the closed half-shells can hold at most 2-3 biopsy samples.
- Another problem connected with the need to perform a plurality of introductions and withdrawals of the forceps consists of the long duration of this procedure which is due, amongst other things, to the need to empty the half- shells. Owing to the small size of the samples taken, this operation in fact takes the operator a considerable amount of time. In operative practice, however, the time available in certain conditions, for example, with markedly intolerant patients who are unable to take sedatives - may be very limited, so that the use of conventional forceps is difficult .
- the subject of the present invention is forceps of the type described at the beginning of the present description and characterized in that it has at least one container element having a cavity for receiving a plurality of biopsy samples .
- the forceps of the invention can therefore be used to take all of samples necessary for a given pathological condition, in succession, by performing only one introduction and withdrawal, thus considerably reducing the time required for the operation, as well as the wear of the endoscope duct.
- the container element keeps the biopsy samples isolated from the duct, which has the advantage of preventing any mixing with impurities or with any scraps remaining from other samples taken, which may be present therein.
- Figure 1 is a schematic plan view of a forceps of the invention
- Figure 2 is a front elevational view of the forceps of Figure 1 .
- Figure 3 is a section view taken on the line III-III of Figure 1 ,
- Figures 4 and 5 are respective plan views of each of the two half-shells of a forceps constituting an alternative embodiment of the invention
- FIG. 6 is a section taken on the line VI-VI of Figure 4,
- Figure 7 is a section view taken on the line VII-VII of Figure 5 .
- Figures 8 and 9 are views corresponding to Figures 5 and 7 , respectively, of a further embodiment of a detail of a forceps of the invention.
- a biopsy forceps for example, for endoscopic biopsy, comprises ( Figures 1-3) two half-shells 10a, 10b each having a front rim 12 and a base wall 14.
- the half-shells 10a, 10b are mounted in conventional manner, for example, on a support element 16 so that they can adopt a first, opened- out configuration (shown in the drawings) and a second, closed configuration in which the rims 12 of the two half- shells 10a, 10b are in contact with one another.
- the half-shell 10b has, in its base wall 14, a hole 18 which communicates with the cavity 20 inside a beaker-shaped container element 22 associated therewith and having a plurality of through-openings 24 in its walls.
- the material constituting the element 22 is not critical within the scope of the present invention and may be selected, without particular limitations, from those suitable for use in the medical field.
- the half-shell 10a is filled up to approximately a third of its height with filling material 25.
- the forceps is first of all passed through an endoscope duct (not shown in the drawings) , with the half- shells 10a, 10b in the closed configuration, until the forceps is in the desired location close to the internal mucosa of the organ to be biopsied.
- the half-shells 10a, 10b are opened out and closed again several times in succession so as to cut off a corresponding number of biopsy samples .
- the openings 24 allow air and any organic liquids which remain trapped in the cavity 20 of the element 22 to be discharged, further facilitating the movement of the biopsy samples inside the element 22.
- the half- shells 10a, 10b are closed again and the forceps, with its container element 22, can be withdrawn through the endoscope duct .
- the biopsy samples which are enclosed inside the cavity 20 do not therefore have any substantial contact with the duct, which could constitute a potential source of histological contamination.
- FIGS 4 to 7 show an alternative embodiment of the half- shells of a biopsy forceps according to the invention, which half-shells can be mounted on a support element in a manner similar to that described with reference to Figures 1-3.
- the half-shell 10a with which the container element 20 is not associated has ( Figures 4 and 6) a base wall 14 having a central portion 26 which is raised substantially to the level of the rim 12, and an annular, recessed, peripheral portion 28.
- the half-shell 10b on the other hand, ( Figures 5 and 7) has, in its base wall 14, the hole 18 in which the end of the beaker-shaped container element 22 is fixed by means of an annular layer of adhesive 30, this end being open and having a restricted neck.
- the internal cavity 20 of the container element 22 thus constitutes a continuation of the space inside the half-shell 10b.
- the container element 22 also has openings 24 in its base and side walls.
- FIG. 8 and 9 show a variant of the fixing of the container element 22 to the half-shell 10b, which is an alternative to the use of the above-described layer of adhesive.
- the open end of the element 22 has a hooked rim for engaging a rim of complementary shape of the hole 18 of the half-shell 10b. This engagement is preferably secured by a mechanical element such as a spring ring 32.
- both of the half-shells may have their own container elements and/or may have, independently of one another, any shape, for example, with a toothed or serrated rim.
- the container element in turn may have substantially any shape and/or length and/or may be in the form of a net engaged directly on the rim of the associated half-shell.
- the container element may equally well be secured on the respective half-shell immovably, or releasably.
