1. A coeliac tissue-suturing apparatus comprising:
- a flexible tubular member having a passage extending therethrough and inserted into a channel of an endoscope;
a needle having one end concentrically fixed to that end of the tubular member which is inserted into the endoscope and having the other end made into a sharp tip, said needle having substantially the same outer diameter as the tubular member and adapted to protrude from a distal end of the endoscope;
a first-stop receiving chamber communicating with the atmosphere and the passage of the tubular member;
a first stop for setting suturing thread on tissues around a coeliac bleeding spot at the commencement of a suturing operation, said first stop being adapted to fix one end of the suturing thread extended along the tubular member, and normally received in the first stop receiving chamber; and
