Problems solved by technology

[0002] Existing laparoscopic surgery for the removal of muscle tissue such as uterus or fibroids is to use a morcellator to crush the tissue to be removed in the abdominal cavity and then take it out from the minimally invasive opening. In this way, the tissue is likely to remain in the abdominal cavity, such as For malignant tumors, there is an increased risk of tumor stage
Moreover, the existing surgical equipment for removing abscess is quite different from abscess and muscle tissue, one is skin fluid, the other is solid muscle tissue, and the excision methods are different, so the two types of equipment cannot be shared

Embodiment 1

[0035] An abdominal cavity extraction device, comprising a sleeve 1, an extraction assembly located in the sleeve, and a sealing and fixing assembly located at the rear end of the sleeve; the extraction assembly includes an extraction bag 2 with a closing rope 21 at the mouth of the bag for The bracket for opening the retrieval bag is used to push the retrieval bag out of the casing and is detachably connected with the bracket and the rear end passes through the pushing operation rod 3 at the outer end of the casing; the retrieval bag is provided with an auxiliary operation hole 22 , and the closing rope passes through the rear end of the casing along the inner cavity of the casing; the sealing and fixing assembly includes a sealing membrane valve 4 with a sealing layer composed of at least two sealing membrane flaps 42 .

[0036] Through the setting of the bracket, the retrieval bag pushed out by the push operation rod can be automatically unfolded, and because the mouth of the ...

Embodiment 2

[0041] The difference from the above embodiment is that the bracket includes a connection plate 51 with a through hole in the center, several first struts 53 whose rear ends are hinged on the connection plate, and each first strut is hinged to a second strut at the front end. 54. The front ends of all the second struts are hinged on an end connection plate 55; the push operation rod includes a thicker rear end main push section 32 and a thinner front end extension section 33, and the rear end main push section diameter is larger than the diameter of the through hole, and the diameter of the front end stretching section is smaller than the diameter of the through hole; the front end of the first strut is located outside the hinged position to set a limit piece 531, and the limit piece is provided with an arc opening facing the connection The limit guide arc in the center of the disc, (it is also possible to use an arc-shaped sheet or a flap with a fold to set baffles on both sid...

Embodiment 3

[0046] The difference from the above embodiments is that the sealing membrane valve includes a valve sleeve 41 detachably sleeved on the rear end of the casing and has a central cavity, the sealing layer is arranged on the central cavity, and the sealing layer There are several diaphragm gaps intersecting at the center of the sealing layer radially on the top, the sealing layer area between the adjacent diaphragm gaps is a sealing valve, and all the sealing valves on each sealing layer are combined to form a cone tip For the tapered sealing layer facing the front end of the casing, 1-3 layers of sealing layers are arranged on the central cavity.

[0047] Each sealing layer includes 3-6 sealing membrane flaps; the sealing membrane flaps include a connection part for fixing the valve sleeve near the wall of the central through cavity, and a rear end of the casing near the center of the central through cavity. The anti-deformation repositioning part 421 protruding in the directio...

Abstract

The invention relates to the field of minimally invasive abdominal surgery, in particular to an abdominal cavity material obtaining device. The abdominal cavity material obtaining device comprises a cannula, a material obtaining assembly located inside the cannula and a sealing fixing assembly located at the rear end of the cannula. The material obtaining assembly comprises a material obtaining bag, a bracket and a pushing operation rod, wherein a bag opening of the material obtaining bag is provided with a reefing line, the bracket is located inside the material obtaining bag and used for opening the material obtaining bag, the pushing operation rod is used for pushing out the material obtaining bag from the cannula and detachably connected with the bracket, and the rear end of the pushing operation rod penetrates out of the outer end of the cannula. An auxiliary operation hole is formed in the material obtaining bag. The reefing line penetrates out from the rear end of the cannula along an inner cavity of the cannula. The sealing fixing assembly comprises a sealing membrane valve with a sealing layer composed of two sealing membrane flaps. The abdominal cavity material obtaining device is simple and stable in structure, processing is convenient, the surgery operation is convenient, both material containing and smashing are performed inside an abdominal cavity, the observation field is wide through an endoscope, no dead angle exists, and tissue is removed thoroughly. The surgery time is short, and smashing can be performed only by one person.

Description

technical field [0001] The invention relates to the field of minimally invasive laparoscopic surgery, in particular to an abdominal cavity retrieval device. Background technique [0002] Existing laparoscopic surgery for the removal of muscle tissue such as uterus or fibroids is to use a morcellator to crush the tissue to be removed in the abdominal cavity and then take it out from the minimally invasive opening. In this way, the tissue is likely to remain in the abdominal cavity, such as If it is a malignant tumor, there is an increased risk of tumor stage. And the existing operation equipment of removing abscess is because there is big difference between abscess and muscular tissue, and one is skinny fluid, and the other is solid muscular tissue, and excision mode is different, and two kinds of equipment can not share. Contents of the invention [0003] The object of the present invention is to provide a laparoscopic object retrieval device for the above problems. [0...
