Abstract
Description
Technical Field
[0001] The invention relates to a minimally invasive surgical assisting device. Background Art
[0002] Single-port laparoscopic surgery is a new minimally invasive treatment method that inserts instruments for observation and cutting through an incision in the umbilicus of the abdominal wall or through a natural cavity such as an incision at the apex of the vagina. Large pieces of diseased tissue or organs removed laparoscopically are placed in traditional single-layer specimen bags, pulled to the incision, and the tissue is removed by manual shredding. The bag is in close contact with the tissue specimen and lacks space. The specimen bag may be damaged if not handled with care, causing leakage of diseased tissue and iatrogenic dissemination and metastasis, and may even directly damage organs such as the intestines in the pelvic and abdominal cavity. In addition, traditional electric tissue rapid pulverizers cannot be used due to lack of operating space. Therefore, the operation time for removing large pieces of diseased tissue or organs is prolonged.
[0003] In addition, a single-hole closed access platform is used to connect the closed bag mouth, and after the traditional single-layer specimen bag is inflated to form a space, a laparoscope is inserted for observation, and then an electric tissue rapid crusher is inserted to crush the specimen. Since the laparoscope and tissue specimen are in the same inflated space, tissue debris will splash onto the surface of the laparoscope body and the single-hole closed access platform, causing instrument contamination and affecting subsequent surgical use. Summary of the invention
[0004] The present invention is to avoid the shortcomings of the above-mentioned prior art. It adopts single-layer and double-layer retrieval bags, inflation tubes, metal elastic rings, push rods, and sheaths to enter the pelvic and abdominal cavities and accommodate tissue specimens. After inflation, an independent and closed hemispherical space structure can be naturally formed in the pelvic and abdominal cavities. There are tissue specimens and space inside the hemispherical space, and it is completely closed in the pelvic and abdominal cavities. The bag body is connected to the outside of the body through an incision.

[0007] 3. An inflatable self-forming dome protective cover for pulverizing tissue specimens in a single-port laparoscopic operation, characterized in that the double-layer bag bottom is a hemispherical air cushion structure, wherein an outer membrane (111) and an inner membrane (131) are connected by a plurality of rivets (12) to form a hemispherical cavity, an inner bag opening (112) of the double-layer bag bottom is sealed and connected to the circumference of the single-layer bag body (13), and the space between the inner membrane (131) and the outer membrane (111) of the double-layer bag bottom is connected to form an air cushion-type closed hemispherical cavity.
[0008] 4. An inflatable self-forming dome protective cover for crushing tissue specimens in a single-port laparoscopic operation, characterized in that the single-layer bag body is a hollow cylindrical structure composed of a single-layer membrane, the distal periphery is connected to the inner bag opening (112) of the double-layer bag bottom, and the proximal end of the single-layer bag body is an outer bag opening (17) connected to a metal elastic ring (15).
[0009] 5. An inflatable self-forming dome protective cover for crushing tissue specimens in a single-port laparoscopic operation, characterized in that the metal elastic ring (15) is a circular ring structure connected to the outer bag opening (17) of the single-layer bag body, and the metal elastic ring (15) is connected to the threaded buckle (321) and the cylindrical push rod (32).
[0010] 6. An inflatable self-forming dome shield for pulverizing tissue specimens in a single-port laparoscopic operation, characterized in that the inflatable tube is a hollow tubular structure, one end of which is connected between the outer membrane (111) and the inner membrane (131) of the double-layer bag bottom, and the other end is connected to a valve.
[0011] 7. An inflatable self-forming dome protective cover for pulverizing tissue specimens in a single-port laparoscopic operation, characterized in that a push rod (32) is a cylindrical structure, one end of which is threaded with a buckle (321), and the other end is connected to a hand-held handle (3).

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: The air cushion inflated and molded into a dome shape by the present invention forms an independent hemispherical space with tension in the pelvic and abdominal cavity. The hemispherical shape expands outward in the pelvic and abdominal cavity, pushing organs such as the intestine and omentum to the outside of the ball and away from the incision, while the internal space of the hemispherical shape is completely sealed in the pelvic and abdominal cavity, and the bag opening is connected to the outside through an incision in the abdominal wall or the top of the vagina. In view of the large incision of single-port laparoscopic surgery, it is possible to directly observe through the bag opening of the incision and use manual or electric crushing to remove tissue specimens. There is enough space between the specimen bag and the specimen, which effectively avoids damage to the specimen bag when crushing the tissue specimen, avoids damage to the pelvic and abdominal organs, and has the safety conditions for electric crushing.
[0014] Since the air cushion space formed by the inflation pressure and the crushed tissue specimens are two completely isolated independent spaces, tissue debris is prevented from contaminating the laparoscope and the single-port closed access platform, and does not affect the subsequent use of these instruments in surgery.

[0017] The surgeon holds the handle (3) and inserts the sheath tube (2) into the single-hole closed access platform, pushes the push rod (32), and the metal elastic ring (15) together with the single-layer and double-layer retrieval bags (1) enter the pelvic and abdominal cavities. The metal elastic ring expands the outer bag opening (17), and the excised tissue specimen (9) is placed in the bag. The inflation tube (14) is pulled out of the incision, and the sheath tube (2) and the push rod (32) are pulled to retract the outer bag opening (17) to the outside of the incision (10). Gas is injected through the inflation tube (14), and the single-layer and double-layer retrieval bags (1) are filled. The double-layer bag bottom (11) is sealed and expanded to form a hemispherical body. Since the double-layer membranes are connected by rivets, the spaces between the double-layer membranes are interconnected. The double-layer bag bottom (11) expands to form a hollow hemispherical space. When the outer membrane (111) of the double-layer bag bottom (11) expands outside the bag, it pushes the surrounding pelvic and abdominal organs such as the intestine (4), mesentery, omentum, and bladder, and continues to pull the single-layer bag body (13) through the incision (10). The outer bag opening (17) is pulled outward through the incision, and the inner bag opening (112) is pulled inside the abdominal cavity to the side of the incision.
[0018] The tissue specimen (9) in the double-layer bag bottom (11) is observed with the naked eye through the passageway between the outer bag opening (17) and the inner bag opening (112), an electric crushing cutter (6) is placed, and the tissue specimen (9) is crushed and removed in the hemispherical space formed by the double-layer bag bottom (11), and the inflation tube switch (141) is turned on to discharge the gas in the air cushion structure formed by the hemispherical inner membrane (131) and the outer membrane (111) of the double-layer bag bottom (11), and the single-layer bag body (13) is pulled outward, and the double-layer bag bottom (11) is removed from the pelvic and abdominal cavity through the incision (10).
[0019] The above embodiments are only descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the spirit and essence of the design of the present invention, any equivalent changes or modifications made to the present invention should be included in the protection scope of the present invention.
