Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
65 words
A trocar sleeve comprising a proximal main body having an axial through-bore, a distal sleeve, and a detachable connection between the distal sleeve and the main body, wherein the distal sleeve has a proximal end formed with a bead and wherein a cap is mounted on said proximal end engaging the bead, the cap being detachably attached to the main body to provide said connection.
Claim 2
Dependent Claim
65 words
A trocar sleeve comprising a proximal main body having an axial through-bore, a distal sleeve, and a detachable connection between the distal sleeve and the main body, wherein the distal sleeve has a proximal end formed with a bead and wherein a cap is mounted on said proximal end engaging the bead, the cap being detachably attached to the main body to provide said connection.
Claim 3
Dependent Claim
23 words
A trocar sleeve according to claim 1, wherein the cap has a thread which engages in a complimentary thread on the main body.
Claim 4
Dependent Claim
20 words
A trocar sleeve according to claim 1, wherein the cap is attached to the main body by a bayonet catch.
Claim 5
Dependent Claim
36 words
A trocar sleeve according to claim 1, wherein the cap has two axially adjacent circumferential areas, one of said areas providing the connection with the main body and the other said areas providing a gripping area.
Claim 6
Dependent Claim
18 words
A trocar sleeve according to claim 4, wherein the gripping area is provided with a roughened external surface.
Claim 7
Dependent Claim
27 words
A trocar sleeve according to claim 1, wherein the main body has an annular surface against which the bead is pressed into sealing engagement by the cap.
Claim 8
Dependent Claim
27 words
A trocar sleeve according to claim 1, wherein the distal sleeve is axially aligned with said through-bore in the main body by means of a screw cap.
Claim 9
Dependent Claim
20 words
A trocar sleeve according to claim 1 including a sealing ring fitted between the distal sleeve and the main body.
Claim 10
Dependent Claim
21 words
A trocar sleeve according to claim 1, wherein the distal sleeve comprises a circular cylindrical tube with a bevelled distal end.
Claim 11
Dependent Claim
74 words
A trocar sleeve comprising a proximal main body having an axial through-bore, a distal sleeve, and a detachable connection between the distal sleeve and the main body, wherein the distal sleeve has a proximal end formed with a bead, and a cap mounted on said proximal end engages the bead, the cap being detachably attached to the main body to provide said connection, wherein the cap has a sliding fit on the distal sleeve.
Claim 12
Dependent Claim
74 words
A trocar sleeve comprising a proximal main body having an axial through-bore, a distal sleeve, and a detachable connection between the distal sleeve and the main body, wherein the distal sleeve has a proximal end formed with a bead, and a cap mounted on said proximal end engages the bead, the cap being detachably attached to the main body to provide said connection, wherein the cap has a sliding fit on the distal sleeve.
Claim 13
Dependent Claim
83 words
A trocar sleeve comprising a proximal main body having an axial through-bore, and a distal sleeve having a proximal beaded end which is engaged by a cap having a sliding fit on said distal sleeve and being attachable to said proximal main body to provide a detachable connection between said distal sleeve and said proximal main body, said cap having two axially adjacent circumferential areas, one of said axially adjacent circumferential areas providing said detachable connection and the other providing a gripping area.
Claim 14
Dependent Claim
83 words
A trocar sleeve comprising a proximal main body having an axial through-bore, and a distal sleeve having a proximal beaded end which is engaged by a cap having a sliding fit on said distal sleeve and being attachable to said proximal main body to provide a detachable connection between said distal sleeve and said proximal main body, said cap having two axially adjacent circumferential areas, one of said axially adjacent circumferential areas providing said detachable connection and the other providing a gripping area.
Claim 15
Dependent Claim
