characterized in that it is provided with at least one transparent region, said transparent region having an area of at least 1 cm2 and a thickness less than 200 μm; said transparent region being made of a material or materials with a total transmittance greater than 80%, a clarity greater than 80% and a haze less than 25%. ## Claims ### Claim 1 A laparoscopic morcellation kit, comprising: a laparoscopic morcellation bag comprising at least one film of plastic material, attached such that it defines a surface of the bag: said surface of the bag having a first closed end and a second open end, the second open end being a port for introducing at least one surgical specimen a morcellator, the laparoscopic morcellation bag being also provided with at least one transparent region having an area of at least 1 cm2 and a thickness of 80 μm; an introducer tube containing the laparoscopic morcellation bag folded up therein; and a trocar provided with an inlet for the connection to insufflation devices; wherein: the transparent region of the laparoscopic morcellation bag is made of a material or a combination of materials with a total transmittance greater than 90% measured according to international standard ASTM D 1003, a clarity greater than 90% measured according to international standard ASTM D 1003 and a haze than 4% according to international standard ASTM D 1003; the surface of the laparoscopic morcellation bag has a Shore elastic stiffness greater than A70 measured according to International Standard DIN 53505, an elongation at break greater than 100% measured according to International Standard DIN EN ISO 527, a mechanical breaking strength greater than 40 MPa measured according to International Standard DIN EN ISO 527 and a continuous use temperature greater than 115°C; and the trocar has a diameter between 15 and 20 mm and a length between 70 and 100 mm. ### Claim 2 (depends on 1) The laparoscopic morcellation kit according to claim 1, wherein the transparent region is made of polyurethane, polyester, polypropylene, polyethylene, polycarbonate, silicone and/or combinations thereof. ### Claim 3 (depends on 1) The laparoscopic morcellation kit according to any claim 1, wherein the second open end of the surface of the bag is provided with a drawstring. ### Claim 4 (depends on 3) The laparoscopic morcellation kit according to claim 3, wherein the drawstring is bent into a loop shape surrounding the second open end of the surface of the bag, said loop being part of a taut-line hitch knot type attachment. ### Claim 5 (depends on 1) The laparoscopic morcellation kit according to claim 1, wherein the second open end of the surface of the bag is provided with a flexible ring, with a Shore A hardness ≥90 and shape memory. ### Claim 6 (depends on 5) The laparoscopic morcellation kit according to claim 5, wherein the flexible ring is attached to a drawstring. ### Claim 7 (depends on 1) The laparoscopic morcellation kit according claim 1, wherein the transparent region occupies an area greater than 60% of the total area of the surface of the bag. ### Claim 8 (depends on 1) The laparoscopic morcellation kit according to claim 1, wherein the surface of the bag has a round shape. ### Claim 9 (depends on 1) The laparoscopic morcellation kit according to claim 1, wherein it is provided with at least one hollow comprising an open outer mouth, a side surface hermetically attached to the surface of the bag and a closed bottom hermetically attached to said side surface, the closed bottom furthermore being provided with a transparent region of an area of at least 1 cm2 and a thickness less than 200 μm, and said transparent region being made of a material or a combination of materials with a total transmittance greater than 80%, a clarity greater than 80% and a haze less than 25%. ### Claim 10 (depends on 9) The laparoscopic morcellation kit according to claim 9, wherein the side surface of the hollow has a tubular or trapezoidal shape. ### Claim 11 (depends on 9) The laparoscopic morcellation kit according to claim 9, wherein the hollow is provided with at least one projecting tab. ### Claim 12 (depends on 1) The laparoscopic morcellation kit according to claim 1, wherein the introducer tube is provided with sealing means comprising a stopper, a sealing valve and a check valve being provided in said stopper.
