Abstract
Abstract The thread (1) has a flexible section with two ends. The lower (2) fastening part on the thread first end has a hollow cylinder (5) with a continuous hole (7) through which a surgical needle threads. One end of the hollow cylinder is joined directly or indirectly to the thread section. The free end not joined to the thread section points away from the thread section and leads into a sloping edge (10). The point of the surgical needle protrudes out of the hollow cylinder free end to form a smooth transition surface together with the sloping edge. The thread section second end has a top fastening part (3) consisting of a tube (15) into which the hollow cylinder fits. The top and lower fastening parts are joined by at least one lug (23) fitting into a recess (11).

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
230 words
Thread for making a surgical suture, comprising: a) a thread portion (1), which is formed from a flexible material and has a first
end and a second end, b) a lower closure part (2) on the first end of the thread portion (1), which has a cylinder (5), which is indirectly or directly connected to the thread portion (1) via one of
its ends, and the free end of which cylinder, not connected to the
thread portion (1), points away from the thread portion (1), and extends at its free end into a sloping edge (10), c) an upper closure part (3) on the second end of the thread portion (1), which
comprises a tubular part (15), into which the cylinder (5) is insertable, and d) means (11, 23), whereby the upper closure part (3) can lock with the lower
closure part (2), characterised in that e) the cylinder (5) is a hollow cylinder with a through-bore (7), the bore (7) of the hollow cylinder (5) being configured in such a
manner that a surgical needle (120) is insertable, so that the point (121) of the surgical needle protrudes from the free end of
the hollow cylinder (5) and forms, together with the sloping edge (10), a smooth transitional
surface, and f) the tubular part (15) of the upper closure part (3) is in the form of a square
tube.
Claim 2
Dependent Claim
78 words
Thread according to claim 1 having the lower closure part (2), wherein the
hollow cylinder (5) is raised on a discontinuous plate (4), which is connected
to the thread portion (1) and has a frustoconical, through-bore (8) provided
with a smaller opening and a larger opening, the smaller opening of which
faces the hollow cylinder (5) and is in alignment with the bore (7) thereof, and
the greater opening of which is remote from the hollow cylinder (5).
Claim 3
Dependent Claim
56 words
Thread according to claim 1 or 2, wherein the means, whereby the upper
closure part (3) can lock with the lower closure part (2), comprise at least one
projection (23) in the interior of the tubular part and at least one recess (11)
on the hollow cylinder (5), the projection (23) engaging in the recess (11).
Claim 4
Dependent Claim
52 words
Combination, comprising a transfer holder (30) for handling purposes and the
thread according to one of claims 1 to 3, with the transfer holder comprising a) a bifurcated head (31a), which has recesses (32) for accommodating
both the lower closure part (2) and the upper closure part (3), and b) a handle.
Claim 5
Dependent Claim
223 words
Combination, comprising a surgical suturing instrument for making a surgical
suture and the thread according to one of claims 1 to 3, the surgical suturing
instrument comprising a) an applicator shaft (40), which has a distal end, which is to be inserted into the body of a
patient, and a proximal end, and comprises an inner shaft part (42) and an outer shaft tube (41)
which is axially displaceable relative to the internal shaft part
(42), b) two jaws (102, 103) on the distal end of the applicator shaft (40), which jaws
are situated opposite each other and can be moved towards each other and
away from each other, c) a multi-part gripping part (52, 53) on the proximal end of the applicator shaft
(40) for actuating the jaws (102, 103), one part (52) of which is connected to
the internal shaft part (42), and an additional part (53) is connected to the
outer shaft tube (41), d) the jaws (102, 103) being formed from a resilient material and assuming,
without the action of force, a V-shaped position relative to each other, and e) one of the two jaws (102) being provided at its distal end with a needle (120),
which extends into a point (121), and the maximum length of which
corresponds to the internal diameter of the outer shaft tube (41).
Claim 6
Dependent Claim
62 words
Combination according to claim 5, having means which render possible a distal advancing movement of the jaw (102), which is provided
with the needle (120), relative to the jaw (103), which is situated
opposite thereto, and/or a proximal withdrawing movement of the jaw (103), which is not
provided with the needle (120), relative to the jaw (102), which is
situated opposite thereto.
