Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
168 words
A forceps having a handle with two resiliently spread apart gripping arms of which one is movable towards and away from the other which is immovable, and an exchangeable forceps insert comprising a tubular shaft which has at its distal end region a forceps aperture and proximally a coupling member joined to the shaft and firmly connectible to the immovable gripping arm, and a thrust rod for closing and opening the forceps aperture, extending through the shaft and terminating proximally in a coupling head which is connectible to a carriage that is mounted on the immovable gripping arm for displacement by the movable gripping arm characterized in that the carriage is lockable in a position in which the gripping arms are pressed together and the forceps aperture is closed, and in that the coupling member is provided with two axially spaced apart inner end stops against which a peripheral stop carried by the thrust rod can abut, thereby to define advance and return strokes of the thrust rod.
Claim 2
Dependent Claim
168 words
A forceps having a handle with two resiliently spread apart gripping arms of which one is movable towards and away from the other which is immovable, and an exchangeable forceps insert comprising a tubular shaft which has at its distal end region a forceps aperture and proximally a coupling member joined to the shaft and firmly connectible to the immovable gripping arm, and a thrust rod for closing and opening the forceps aperture, extending through the shaft and terminating proximally in a coupling head which is connectible to a carriage that is mounted on the immovable gripping arm for displacement by the movable gripping arm characterized in that the carriage is lockable in a position in which the gripping arms are pressed together and the forceps aperture is closed, and in that the coupling member is provided with two axially spaced apart inner end stops against which a peripheral stop carried by the thrust rod can abut, thereby to define advance and return strokes of the thrust rod.
Claim 3
Dependent Claim
107 words
A forceps as claimed in claim 1, charac- 3 GB 2 140 735A 3 terized in that the carriage is lockable by means of a locking element which is rotatable with or around a spindle extending at right angles to the upper proximal side of the immovable gripping arm which in an advanced position of the carriage is placed against its proximal end side and by rotation under the resilient spreading apart of the movable gripping arm authorises the return stroke of the carriage via a flat.peripheral portion or peripheral recess, and is releasably immobilised in each of the two terminal positions by means of detent devices.
Claim 4
Dependent Claim
22 words
A forceps as claimed in claim 1 or 2, characterized in that the two end stops are displaceable in the coupling member.
Claim 5
Dependent Claim
70 words
A forceps as claimed in any one of claims 1 to 3, characterized in that one of the end stops in the coupling membdr limits the closing positions of the forceps aperture and the other end stop limits the opening position of the forceps aperture, the maximum closing and opening angle which may be set being larger than required for the purpose of adapta- tion to different exchangeable forceps inserts.
Claim 6
Dependent Claim
31 words
A forceps as claimed in any one of the claims 1 to 4, characterized in that a tube which surrounds the thrust rod is provided for sealing and for lateral support.
Claim 7
Dependent Claim
44 words
A forceps substantially as hereinbefore described with reference to the accompanying drawings. Printed in the United Kingdom for Her Majesty's Stationery Office, Dd 8818935, 1984. 4235. Published at The Patent Office, 25 Southampton Buildings, London. WC2A 1AV, from which copies may be obtained. 1
