A spring-loaded reciprocable styles holder assembly (39) includes a cap (40); a hollow body element (41) partially nested within and reciprocable a major part of its length into the cap; a spring (54) urging the body element outwardly of the cap; and a styles (42) supported at one end by the cap and extending through and beyond the body element. The remote end of the body element (41) has a small borehole (45) through which the styles (42) extends. The remote end is also provided with attachment means for a hypodermic needle (47) with slotted tip (51) for T-fastener (48) emplacement, the needle telescopically surrounding the full length of the stylet. In a useful modification of the device and insufflation adapter (90) having a side port (94) for attachment of a hypodermic syringe is placed in line between the body element and the hypodermic needle. The styles holder assembly (39) with a slotted hypodermic (47) needle attached thereto may be used for emplacing a T-fastener (48) in a hollow organ of a person, such as the stomach.

Un ensemble porte-stylet (39) chargé par ressort et à va-et-vient comprend un capuchon (40); un corps creux (41) à va-et-vient partiellement emboîté sur une partie de sa longueur dans le capuchon; un ressort (54) poussant le corps à l'extérieur du capuchon; et un stylet (42) supporté à une extrémité par le capuchon et s'étendant dans ledit corps et au-delà. L'extrémité distale du corps (41) comporte un petit alésage (45) dans lequel s'étend le stylet (42). L'extrémité distale est également pourvue d'un élément de fixation destiné à une aiguille hypodermique (47) à pointe fendue (51) dans laquelle s'adapte un élément de fixation en T (48), l'aiguille entourant totalement le stylet de manière télescopique. Selon une modification utile apportée au dispositif, un adaptateur d'insufflation (90) comportant un orifice latéral (94) servant à fixer une aiguille hypodermique est placé dans l'axe entre le corps et l'aiguille hypodermique. L'ensemble porte-stylet (39) auquel est fixé une aiguille hypodermique fendue (47) peut être utilisé pour positionner un élément de fixation en T (48) dans un organe creux d'un patient, tel que l'estomac.
