[0002] In the existing tools for taking out specimens in laparoscopic surgery, sterile bags are usually used to take out the biological tissues cut by surgical forceps in laparoscopic surgery. During this process, blood and water cannot be cleaned, so it is not possible to clearly It is difficult to see the position of the biological tissue, and because the incision is small, it is not convenient for the steel wire and the sterile bag to go deep into the body. In addition, when the cut biological tissue is large, the surgical forceps cannot be completely cut off at one time, resulting in the inability to The cut-off part of the biological tissue is fixed and pulled, so it is not convenient for the next cutting operation. In view of this, we propose a biological tissue specimen removal device for laparoscopic surgery

The invention relates to the field of medical equipment, in particular to a device for taking out biological tissue specimens for laparoscopic surgery, including a laparoscopic sleeve, and a ventilation duct, which is used to pick up the tissue cut off by surgical forceps on the laparoscopic sleeve. For biological tissue samples, a hoop is provided on the outer wall of one end of the ventilation pipe, and a barb mechanism is provided on the inner wall of the end of the ventilation pipe near the hoop to prevent the biological tissue from falling off. A suction mechanism for absorbing blood and water, the suction mechanism is connected with the barb mechanism through transmission. The device for taking out biological tissue specimens for laparoscopic surgery is convenient for taking out large-volume biological tissues, and prevents biological tissues from falling from the ventilation duct, preventing the fallen biological tissues from possibly containing tumor cells, thereby causing tumors. Improving the reliability of biological tissue removal, and maintaining the integrity of the specimen as much as possible in the process of taking the specimen.

During this process, blood and water cannot be cleaned, so it is not possible to clearly It is difficult to see the position of the biological tissue, and because the incision is small, it is not convenient for the steel wire and the sterile bag to go deep into the body. In addition, when the cut biological tissue is large, the surgical forceps cannot be completely cut off at one time, resulting in the inability to The excised part of the biological tissue is fixed and pulled, so it is inconvenient for the next cutting operation. In view of this, we propose a biological tissue sample removal d...
