Disclosed is a surgical system for small-pit closure in hollow organs having excellent operability, safety, and reliability, and whereby it is possible to reduce the duration and invasiveness of surgery by avoiding major surgical procedures. The surgical system is provided with a surgical device (1, 1A) for small-pit closure in hollow organs, with said surgical device including the following components, which are connected sequentially: a suture-member cartridge (5-5B) in which a pair of parallel tubular members (51) that accommodate respective suture members (100-120) configured of a suture thread (103-143) are feedably connected to the rear ends of a pair of arrowy-shaped members (101-121) that latch into tissue in a hollow organ; an auxiliary shooting unit (3-3B) having plungers respectively provided in a pair of cylinders (31, 31B) open at both ends; a hollow-organ-insertable unit (2, 2A) configured of a pair of flexible air tubes; and a gas shooter (4-4B) that sequentially discharges compressed air or high-pressure gas into the open-ended cylinders in response to operations of a trigger (44-4B4), for sequentially ejecting the arrowy-shaped members and driving the same into tissue in the hollow organ (T) on both sides of a small pit (Tc) site. The surgical device is used, in combination with an endoscope (200, 200A) that is inserted into the hollow organ, for closing and suturing the hollow organ tissue at the small-pit site.

Provided is a boot band 31 that is capable of preventing the occurrence of buckling in the inner-layer portion of a band body 33. In the boot band 31, by applying a diameter-reducing tightening force on the band body 33 when an engagement pawl 41 of the inner-layer portion 35 of the band body 33 has entered a top-end engagement hole 42 of the outer-layer portion 34 of the band body 33, the top-end engagement hole 42 rides over the engagement pawl 41. Buckling is prevented by providing, at the area of the top-end engagement hole 42 opposite where the engagement pawl 41 enters therein, a guide means 51 that faces the engagement pawl 41.

Câble d'énergie et/ou de télécommunication comprenant au moins une couche (4) électriquement isolante qui comporte au moins deux bandes isolantes (61 à 64) superposées, chacune de ces bandes (61 à 64) étant disposée de façon à laisser un déjoint (71 à 74) entre deux de ses spires successives (81 à 84), caractérisé en ce que chaque bande (61 à 64) est disposée de façon décalée par rapport aux bandes (61 à 64) contigües de manière à ce que les déjoints (71 à 74) d'une bande (61 à 64) ne coïncident pas avec les déjoints (71 à 74) des bandes (61 à 64) contigües et soient recouverts entièrement par les spires (82 à 84) des bandes contigües (62 à 64). La couche isolante (4) comporte une substance diélectrique et résistante au feu qui se trouve au contact de chacune desdites bandes isolantes (61 à 64) et s'introduit dans lesdits déjoints (71 à 74).
