Biological tissue specimen taking-out device for laparoscopic surgery

Abstract

The invention relates to the field of medical equipment, in particular to a biological tissue specimen taking-out device for laparoscopic surgery. The device comprises a laparoscopic cannula and a ventilation pipeline, the ventilation pipeline is used for picking up a biological tissue specimen cut off by operating forceps on the laparoscopic cannula, and a hoop sleeve is arranged on the outer side wall of one end of the ventilation pipeline. A barb mechanism used for preventing biological tissue from falling off is arranged on the inner wall of the end, close to the hoop sleeve, of the ventilation pipeline, a suction mechanism used for absorbing blood is arranged on the side wall of the end, close to the hoop sleeve, of the ventilation pipeline, and the suction mechanism is in transmission connection with the barb mechanism. According to the biological tissue sample taking-out device for the laparoscopic surgery, large-size biological tissue can be taken out conveniently, the biological tissue is prevented from falling off from the ventilation pipeline, the situation that the falling biological tissue possibly contains tumor cells, and consequently implantation and metastasis of tumors are caused is prevented, the reliability of taking out the biological tissue is improved, and the integrity of the specimen can be kept as much as possible in the specimen taking process.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a device for taking out biological tissue samples for laparoscopic surgery. Background technique [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 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...
