Abstract:
Disclosed is an anti-slip combined connection device for an extraction bag for crushing under an endoscope and a hard catheter. The device comprises a hollow hard catheter (1), wherein one end of a catheter cavity is in spiral connection with a closure cap (11), the other end of the catheter cavity is externally provided with a catheter baffle (12), and the catheter cavity is internally provided with an internal thread (13) connected to an external thread (23) of a base (2); and the base (2) is of a hollow tubular structure composed of a base sheath tube (21) and a base baffle (22), wherein the base sheath tube (21) externally has the external thread (23) that is connected to the internal thread (13) of the hard catheter; an outer periphery of the tail end of the base (2) is provided with the base baffle (22); a surface of the base baffle (22) is provided with a groove (24); and a thickened washer (32) is provided around a circular hole (31) in the surface of an extraction bag (3). The combined connection of the extraction bag for crushing under a laparoscope and the hard catheter is firm, thereby preventing the hard catheter and the extraction bag from slipping from an abdominal cavity through an abdominal wall puncture hole to outside of the body due to excessive pulling from outside of the body.
