The suturing instrument uses a tissue suturing method consisting in introducing a quick-hardening biocompatible mass (hereinafter referred to as the ‘mass’) into the tissues to be connected or drawing it from them through hollow needles. The instrument has housing (1) with tissue gripping jaws (2 and 3) with control handles (5, 14). One of the jaws contains needle holder (19) with mechanism (17) moving it both ways. The needle holder contains mass receptacle (25, 28) above needles (18) that is connected to needle mouths via damper (33). A mechanism squeezing the mass out of the receptacle is located above the receptacle: inflatable bladder (29) that is open to external source of elevated pressure (31), rod or lock plate (59) with a device securing it to jaw walls (3) or instrument housing walls (1) on needle withdrawal from tissues. The mass receptacle presses against the fixed lock plate on needle lifting, and the mass is uniformly fed into tissues. The instrument can also be mounted on surgical forceps, (FIG. 1).
A surgical suturing device comprising, a housing with control handles at one end and two gripping working jaws at the other, at least one of which being mounted so that it can move relative to the second one, a holder with hollow needles mounted on either jaw, a reciprocating mechanism for hollow needle mounted so that they can interact with the needle holder, as well as a tissue fastening agent, wherein a fluid biocompatible quick-hardening mass placed in a receptacle open to hollow needle channel mouths and equipped with a mechanism ensuring its uniform feed into the tissues to be stitched is used as a fastening agent, and a damper mounted at the receptacle outlet.
