Microsurgical combination instrument for suture positioning using the hollow needle method and for intraluminal one-handed suturing

摘要

This protective microsurgical combination instrument is the union of a "rod element for hollow needle guidance" with a; "Rod element for intraluminal suture" (intraluminal suture instrument) "and optionally with a" knot pusher ". The claims 1. The microsurgical minimally invasive combination instrument for suture positioning with the hollow needle method as well as for transendoscopic or direct intraluminal one-handed Nahtsetzung is characterized as a microsurgical rod element with a combined functionally combined site of action for both hollow needle guidance and intraluminal suture needle guidance. Claim 2. - Characteristics of this microsurgical rod element for hollow needle guide and intraluminal suture according to claim 1 is the shape of the suitable for transendoscopic laparoscopy shaft of 4 to 4.1 mm diameter at the common functional action end, with a 0% cylindrical () to 6 % conical (as 6% (Luer) cone) Hollow needle or cannula attachment (and) - optionally with very flat, slightly increasing right-hand twist - for fixed, load-bearing axial attachment for standardized Luer cannulas. Claim 3. - Characteristic of this functionally combined site of action according to claim 1 is that it acts in the sense of an intraluminal suturing device as a needle holder for specially bent bent needles, which are firmly connected to suture threads to make one-handed minimally invasive transendoscopic or intraluminal seams, this functionally combined Weaving point according to claim 2, characterized in that a one-sided guide slot of the axial bore in the hollow needle approach of the rod element of about 1½ times the width of the needle diameter and at most twice the depth of the diameter of the used special bent bent needles; Thus, such needles are fed and fixed by needle-thread combinations on the connected suture threads in this guide slot. Claim 4. - Characteristic of the microsurgical rod element is the 15 mm to 20 mm below this functionally combined according to claim 1, 2 and 3 active site laterally from the body of the rod element obliquely distally extending outlet of the thread bore. Claim 5. - Characteristic of the microsurgical rod element is the flat on the body of the rod element symmetrical narrowing transverse notch for temporary clamping of suture threads below the thread exit according to claim 4. Claim 6. Characteristic of the microsurgical rod element is a scaling marking at 50 mm intervals , Claim 7. - The functionally combined active site according to claim 1 opposite end of the rod element is designed as a knot gate, to which an axial bore with at most a lumen width of 1½ times the seam thread diameter for thread transfer is attached to the 10 to 20 mm according to claim 4 laterally is discharged to the rod element.
