Abstract

Suture forceps for single sutures, characterized by two corresponding different active sites in the forceps head, in which the one active site as a thread-guiding perforated die ( 1 . 2 ) and the other site of action as a tissue-perforating and string-taking stamp ( 3 ) is designed. This stamp ( 3 ) attacks the of the matrix ( 1 . 2 ) in a guide (2 in 1 , 2 in 2 ) presented after approximately right - angled puncture of the breakthrough of the template (1 in 1 , 1 in 2 ) in a slot (1 in 3 ) and returns this suture.

Description

The Suture forceps for single sutures is one in medicine Applicable technical utility invention invention for surgical-surgical sutures with filamentous Suture with targeted tissue puncture and for positioning there a single or double-lumen suture with any suture material without the use of surgical needles with standard needle holders in the depth of the operation area.

According to the Prior art are commonly used in surgery Seams with thread-like sutures are set in such a way that a suture by means of a forceps-shaped needle holder and a needle passed through the tissue and then after Grasping on the opposite side the puncture pulled through and knotted becomes. These are either prefabricated thread-fixed needles or surgical needles with spring eyelet used. At the current Stand surgical suturing technique for single sutures are mechanically strong and at the same time very simply configured Instruments, but especially sutures, not available. A special seldom used solution are boomerang needle holders (A) in which a movable needle after puncture the thread at the opposite side again; this mechanically complex Devices are to be provided for smaller seams. There is also a sophisticated needle holder with rotating head (B), with which a thread is guided through the tissue and is resumed at the opposite piercing.

to Fixation on or in more rigid tissues become very resilient sutures required, being mostly in the depth of the surgical field lying puncture requires a significant piercing force. Examples for such stable suture fixations are the attachment alloplastic tubular, ribbon or net shape Implant materials or the locking of displaced organs Fascia or ligaments in small-scale descent operations Pool. Also the attachment of stuck individual seams Laparoscopic surgeries require suture instruments that have a Suturing in a work cycle and without encroaching allow.

This Problem is with the claim specified protection claim invention "suture for single seams "so solved that in the tissue depth and in deep areas of the operation area suture pierced through solid, rigid tissue sections and in the same stroke without reaching around the instrument self gripped and returned.

With The invention achieves that in the depth of the operation area (For example, in urological or gynecological operations in the small pelvis or during laparoscopic procedures) a "blind" exact Positioning the seam (ie only by pressing) by means of this Suture forceps for single sutures uncomplicated is. Suture material can also be used in the depth of the instrument Operation area without extensive cutting production accessibility in and around structures (such as Cooking, ligaments, tendons, fascia, vessels, Organs) are introduced and locked.

By means of this suturing forceps for single sutures according to the invention, a suture is also to be placed in very rigid tissue, for example by fascia, scars, tendon plates or cartilage, because the corresponding different effective sites (matrix and punch) in the forceps head efficiently puncture even firmer tissue up to a strength of 20 mm and the subsequent thread passage ensure. According to the invention, according to the invention, the one active site is a thread-guiding pierced matrix ( 2 ) and the other active site as a perforating to the tissue to be sewn and the thread picking stamp ( 3 ) shaped. The piercing force is transmitted either by lever-shaped acting or by parallel acting pliers arms (or commercial) of the suture, the active sites act perpendicular punching each other.

• a) In der Tiefe des Operationsgebietes (zum Beispiel bei urologischen oder gynäkologischen Operationen im kleinen Becken aber auch bei laparoskopischen Operationen in der „Knopflochchirurgie”) ist „blindes” exaktes Positionieren der Naht (also lediglich durch Tasten oder unter Videokontrolle) mittels dieser Nahtzange für Einzelnähte unkompliziert möglich.
• b) Mit dieser Nahtzange für Einzelnähte ist eine Naht auch in sehr rigidem Gewebe, zum Beispiel durch Faszien, Narben, Sehnenplatten oder Knorpel zu setzen.
• c) Als Nahtmaterial ist beliebiges chirurgisches Nahtmaterial angemessener Stabilität verwendbar, wobei keine besondere Ansprüche an Fadenstärke, Fadenstruktur, Rigidität, Oberflächenstruktur oder besondere Konfektionierung bestehen.
• d) Die rasche Fortfolge weiterer Nähte in gleicher Operationssitzung ist wegen sehr einfacher Fadeneinlage in das Instrument gesichert.
• e) Die Nahtzange für Einzelnähte ist ein robustes Instrument und ist durch zwei korrespondierende unterschiedliche Wirkstellen im Zangenkopf charakterisiert; es ist sicher handhabbar und bedarf keiner Justierung oder Montage.
• f) Die Reinigung, Desinfektion und Sterilisierung der aus inoxidablem Material angemesserer Stabilität gefertigten Nahtzange für Einzelnähte ist wegen der einfachen Konfiguration zuverlässig möglich.

The inventive step is that a solution of a suturing forceps for single sutures for suturing with conventional surgical sutures, which was previously not obvious to the skilled person (that is to say for the experienced surgeon), has been developed. The novelty value of the suturing forceps for single sutures is based on utility value properties, which, in the current state of the art of instrumentation of previous surgical suture devices for single sutures, are not coherently present:

• a) In the depth of the operating area (for example, in urological or gynecological operations in the pelvis but also in laparoscopic surgery in the "buttonhole surgery") is "blind" exact positioning of the suture (ie only by pressing or under video control) using this suture forceps for Single seams uncomplicated possible.
• b) With this suture pliers for single sutures, a suture is also to be placed in very rigid tissue, for example by fascia, scars, tendon plates or cartilage.
• c) As a suture material any suitable surgical suture suitable stability is used, with no particular demands on thread strength, thread structure, rigidity, surface structure or special packaging.
• d) The rapid progression of further sutures in the same operation session is because of very simple fade No deposit secured in the instrument.
• e) The suturing forceps for single sutures is a robust instrument and is characterized by two corresponding different effective sites in the forceps head; It is safe to handle and requires no adjustment or assembly.
• f) The cleaning, disinfection and sterilization of the seams made of inoxidablem material of appropriate stability for single seams is reliably possible because of the simple configuration.

The industrial applicability of this particular subject-specific operational Procedures supporting instrument is based on the deductible business advantage for surgical-surgical Service provider, in particular from the extended indication special surgical techniques, which are a tissue-preserving suture must be included in the depth of the tissue

With this sterilizable reusable suture forceps for Single seams can be inexpensive conventional Surgical sutures are processed. A significant cost reduction mainly results from the shorter cutting seam time, reducing the cost of consumables (such as pre-assembled needle thread sets and special applicators for Suturing at tissue depth), the shorter length of stay because of the potentially faster postoperative healing and the lower surgical burden and thus also risk minimization. This results in a cheaper price-performance ratio in surgical-surgical service provision.

An advantageous embodiment of the invention is shown in the claims. Embodiments are based on the 4 and 5 explains; show it 4 a "seaming device for single seams, characterized by two movably connected stably configured arms" and 5 "Suturing forceps for single sutures, characterized by two parallel movably connected stably designed forceps arms".

Claims (5)

Suture forceps for single sutures, characterized by two corresponding different active sites in the forceps head, in which the one active site as a thread-guiding perforated die ( 1 . 2 ) and the other site of action as a tissue-perforating and string-taking stamp ( 3 ) is designed. This stamp ( 3 ) attacks the of the matrix ( 1 . 2 ) in a guided tour ( 2 in 1 . 2 in 2 ) presented after approximately right-angled puncture of the breakthrough of the template ( 1 in 1 . 1 in 2 ) in a slot ( 1 in 3 ) and returns this suture. According to claim 1, the thread-guiding matrix of the suture is characterized by an aligned in the suture plane breakthrough ( 1 in 1 . 1 in 2 ) of the active site, for the entry of the material to be sewn by the piercing and the suture thread in a slot detecting tapered punch ( 1 in 3 ), as well as a thread-perpendicular breakthrough ( 2 in 1 . 2 in 2 ). This arranged transversely to the longitudinal axis yarn-conducting breakthrough can be used as a bore ( 2 in 1 ) or as forward and obliquely upward slits ( 2 in 2 ). According to claim 1, the thread-engaging stamp-like active site is characterized by a tip asymmetrically tapering punch for tissue perforation ( 3 ), which in the inside has an obliquely inwardly forwardly extending and rearwardly open aligned slot ( 1 in 3 ). If this stamp, after penetrating the material to be sewn, penetrates into the opening of the die, the latter becomes transverse to this slot (FIG. 1 in 3 ) in the thread-leading breakthrough ( 2 in 1 . 2 in 2 ) lying suture with just this slot ( 1 in 3 ) captured. When divergence of the active sites, so when opening the suture forceps ( 4 . 5 ), the one with this slot ( 1 in 3 ) is taken back from the opening of the die ( 1 in 1 . 1 in 2 ). Suture forceps for single sutures according to one of the preceding claims ( 4 ) characterized by two movably connected stably configured arms ( 1 and 2 in 4 ) which is shaped by a joint designed as a laid-up or 3 in 4 ) are connected like a pliers. These arms carry the corresponding active sites, namely (according to the preceding claims 2 and 3) die and punches of the pliers head, wherein the axes of the active sites to the axis line of the pliers arms can be angled so far that always the punch is arranged to the die sufficiently rectangular ( 5 Angle α in 4 . 5 Angle α in 5 ). Thus, during the movement of the forceps arms, the approximately right-angled puncture of the corresponding different action points on the forceps head, namely that of the thread-guiding die ( 3 in 4 ) and the perforating thread-taking punch ( 4 in 4 ) and thus after tissue puncture of the suture ( 5 in 4 ) and returned. Suturing forceps for single sutures according to one of the preceding claims, characterized by two pliers arms ( 5 ). These pliers arms carry the corresponding sufficiently perpendicular to each other arranged active sites of the pliers head ( 5 Angle α in 5 ), namely (according to the preceding claims 2 and 3) die and punches. Thus, the approximately right-angled puncture (angle α in 5 ) the thread-guiding die ( 3 in 5 ) with the perforating thread-taking punch ( 3 in 5 ) and so after tissue puncture of the suture ( 7 in 5 , respectively. 6 ) and returned.
