Problems solved by technology

[0002] Laparoscopic surgery is to puncture the abdominal wall to form multiple tiny puncture holes. After inflating the abdominal cavity, the abdominal cavity is inflated to form a space for surgical operations in the abdominal cavity and expose the tumor to be removed. Surgical instruments are used to remove the tumor from the normal tissues or organs of the human body in the abdominal cavity. During the whole process of tumor removal, solid tumors may be contaminated by tumor cells or tumor debris due to forceps tearing and other reasons. Abdominal cavity: Cystic tumors may overflow and leak tumor contents and contaminate the abdominal cavity due to clamp tearing and other reasons, thus iatrogenicly causing distant metastasis and recurrence of the tumor, which seriously threatens the life safety of patients
[0003] In order to prevent the implantation and metastasis of exfoliated tumor cells in the peritoneal cavity, the current method is mainly to flush the surgical wound and the peritoneal cavity with a large amount of normal saline or distilled water after tumor resection, hoping to ensure that no exfoliated tumors remain in the peritoneal cavity through flushing cells, but the remedial measure of relying on fluid flushing the peritoneal cavity is a helpless and passive measure after the fact that the peritoneal cavity has been contaminated by tumor cells. In clinical practice, it is difficult to satisfy expectations, and tumor recurrence and metastasis often occur due to this.

Abstract

The invention provides an isolation device for preventing tumor cells from falling off under a laparoscope, which belongs to the technical field of laparoscopic surgery auxiliary devices and comprisesa tumor cell isolation bag, a glue spraying pipe and an injection device filled with biological albumen glue. The tumor cell isolation bag comprises a flexible fixing layer and a gauze layer; whereinthe flexible fixing layer is made of medical plastic or medical rubber, the edge of the flexible fixing layer is sewn or bonded with the gauze layer, the flexible fixing layer and the gauze layer define a biological albumen glue filling space, the shape of the flexible fixing layer and the shape of the gauze layer are matched with the shape of a tumor cell exposed surface, and the gauze layer isattached to the tumor cell exposed surface; the front end of the glue spraying pipe penetrates through the flexible fixing layer and extends into the bioprotein glue filling space, and the rear end ofthe glue spraying pipe is connected with a glue outlet of the injection device. The device can be placed in the abdominal cavity before tumor cells are excised, falling tumor cells or overflowing tumor cell contents are prevented from dispersing in the abdominal cavity, are isolated from a human body and are prevented from being in direct contact with normal human tissues and organs, so that theaim of preventive treatment is fulfilled.

Description

technical field [0001] The invention belongs to the technical field of laparoscopic operation auxiliary devices, and specifically discloses a laparoscopic anti-tumor cell shedding isolation device. Background technique [0002] Laparoscopic surgery is to puncture the abdominal wall to form multiple tiny puncture holes. After inflating the abdominal cavity, the abdominal cavity is inflated to form a space for surgical operations in the abdominal cavity and expose the tumor to be removed. Surgical instruments are used to remove the tumor from the normal tissues or organs of the human body in the abdominal cavity. During the whole process of tumor removal, solid tumors may be contaminated by tumor cells or tumor debris due to forceps tearing and other reasons. Abdominal cavity: For cystic tumors, the contents of the tumor may overflow and leak to contaminate the abdominal cavity due to forceps tearing and other reasons, thus iatrogenicly causing distant metastasis and recurrenc...
