Abstract
Abstract A device for the removal of anatomical parts by laparoscopy, comprising a bag to be inserted by means of a tube applicator inside the abdominal cavity. A flexible element is provided along the edge of the mouth of the bag, having such resilient characteristics as to spring back to a loop configuration when it is not subjected to a deformation. According to a preferred embodiment, the flexible element is formed by a helicoidal spring with a ring clip slidingly coupled thereto, so that the resilient action of the spring keeps the mouth open when the bag is inserted in the abdominal cavity, and by making the clip to slide along the spring it is possible to close again the bag when needed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
110 words
A device for removing anatomical parts in surgical operations carried out by laparoscopy, comprising a bag, a tube applicator in which the bag is arranged for being introduced in an abdominal cavity, means for ejecting the bag from the tube applicator into said cavity, a flexible closed linear element associated with the bag along its mouth, having an elastic behavior so as to spring back in a loop configuration when the bag is outside the tube applicator, wherein the flexible element is slidingly coupled with a ring-shape clip which defines two lobes having substantially loop forms of variable dimensions following the reciprocal sliding between the flexible element and the clip.
Claim 2
Independent Claim
110 words
A device for removing anatomical parts in surgical operations carried out by laparoscopy, comprising a bag, a tube applicator in which the bag is arranged for being introduced in an abdominal cavity, means for ejecting the bag from the tube applicator into said cavity, a flexible closed linear element associated with the bag along its mouth, having an elastic behavior so as to spring back in a loop configuration when the bag is outside the tube applicator, wherein the flexible element is slidingly coupled with a ring-shape clip which defines two lobes having substantially loop forms of variable dimensions following the reciprocal sliding between the flexible element and the clip.
Claim 3
Dependent Claim
15 words
A device according to claim 1 , wherein the flexible element is a helicoidal spring.
Claim 4
Dependent Claim
36 words
A device according to claim 1 , wherein the flexible element is folded into a figure 8 profile and wherein the clip is arranged astride a junction of the two lobes forming said figure 8 profile.
Claim 5
Dependent Claim
56 words
A device according to claim 1 , wherein the means of the tube applicator for ejecting the bag comprises a ram that slides longitudinally inside the tube applicator, operated by a stem passing through a proximal end of the tube applicator, and wherein the applicator is provided with means for making a seal on the stem.
Claim 6
Dependent Claim
20 words
A device according to claim 4 , wherein the means for making the seal on the stem comprises a membrane.
Claim 7
Dependent Claim
19 words
A device according to claim 4 , wherein the tube applicator further comprises means for hooking the flexible element.
Claim 8
Dependent Claim
22 words
A device according to claim 6 , wherein the means for hooking the flexible element comprises a hook portion of the ram.
Claim 9
Dependent Claim
30 words
A device according to claim 1 , wherein the bag is arranged inside the tube of the related applicator and is rolled around the flexible element or a part thereof.
Claim 10
Dependent Claim
25 words
A device according to claim 1 , wherein the bag comprises a member selected from the group consisting of polyurethane, an aramid fiber and polypropylene.
