Ligation ring mounting plate, syringe and scope；The ligation ring, which is set in, pricks inner tube front outermost, and the set pricks outer tube package
Inner tube lateral surface is pricked in set, the front of set bundle outer tube is relatively thin, is normally in contraction state, set pricks outer tube and set bundle inner tube lateral surface is tight
Closely connected attached, set pricks the front end of outer tube in open or closed, the rear portion that set pricks outer tube continue thicken to be formed can with before scope
The connecting tube that end cap connects, set are pricked outer tube and are connected to by connecting conduit with the syringe interface of syringe, the ligation ring rack tube
It is put into the circular hole of ligation ring mounting plate, ligation ring rack tube can freely slide up and down in circular hole.
The syringe for being provided with side opening can be used in the syringe.
Elastic ligation ring can be used in the ligation ring, and high resiliency O shape cushion rubber can be used in the elasticity ligation ring.
The set, which pricks inner tube, can be used hard transparent plastic casing, and the set, which pricks outer tube, then can be used elastic thin-wall transparent sheath
Pipe.
The set constitutes a closed lacuna, set bundle inner tube after pricking inner tube and the one or both ends processing bonding of set bundle outer tube
The back body for pricking outer tube with set is that set bundle outer tube continues integrally formed heavy wall resilient connection sebific duct, by coupling sebific duct part
The front that set can be made to prick outer tube securely connects together with scope front end portion.
The closed lacuna then passes through an elongated soft connecting conduit and is connected with syringe, is led by syringe through connection
When the set of pipe forwards pricks gas injection in outer lumen, set pricks outer tube will constantly expand increase in ring week capsule column, form expansive force, right
It is placed in the ligation ring that set is pricked in front of outer tube lateral surface in advance and generates and makees to the successively incremeantal launching method that set bundle inner tube and set are pricked in front of outer tube
With the continuous forward direction of ligation ring rolls until arrival set pricks inner tube and set bundle outer tube front end and falls off, and rapid elastical retraction restores
To the lesser original shape state of diameter, and then complete set bundle movement.
