Suture Needle Patent
 

Suture needle

A suture needle has a unique structure for reducing impalement resistance. The suture needle is formed with a base end portion formed at an end of the suture needle for engaging a suture thread, a tip portion formed at another end of the suture needle for impaling a tissue, and a tapered portion extending to the tip portion. The tapered portion has a cross-section without a cutting edge and a plurality of roughened regions formed in stripes extending in a substantially axial direction of the tapered portion. The roughened regions are provided solely on the tapered portion of the suture needle. The surface roughness of the roughened regions on the suture needle is about 2 .mu.m-15 .mu.m.

Device for inserting a surgical suture needle into an endoscopic suture apparatus

In a device for inserting a surgical suture needle into an endoscopic suture apparatus wherein the device includes two legs which are movable relative to each other, one of the legs has a front end with means for receiving a jaw of an endoscopic suturing apparatus and the other leg has needle engagement means for holding a surgical needle in a predetermined position such that one needle tip enters a needle support of the surgical suturing apparatus jaw when the other leg holding the needle is moved toward the one leg while the one leg is disposed on the surgical suturing apparatus jaw.

Suture needle park and collector

A suture needle holder includes a hollow holder portion which is preferably molded from a clear plastic, and a base portion coupled to a lower portion of the holder portion. A lower side of the base portion is provided with an adhesive. The holder portion is provided with at least one needle park which can be integrally molded with the holder portion. The holder portion also includes an opening through which used suture needles can be disposed into the hollow holder portion. The surgeon is able to see into the clear holder portion and make an accurate count of how many suture needles have been used. The adhesive on the base member enables the holder to be positioned on the surgical drape and prevents unintentional movement of the holder, and further facilitates single-handed use of the holder. In a preferred embodiment, the hollow holder portion is shaped like a hexagonal frustum and includes a needle park on each of its six sloped faces. Each needle park is formed by two inwardly angled walls, the walls able to frictionally engage the shaft of a suture needle. The holder portion is provided with a raised portion around which suture material may be thread to assist a physician in tying off suture. The opening is provided on the raised portion and includes a tapered entryway which prevents disposed needles from exiting the opening.

Laparo-suture needle and method for use thereof

A laparo-suture needle and method for use thereof. A medical suturing instrument employs an outer, hollow shaft having a laterally-disposed, elongate handle at a proximal end and an elongate, inner shaft disposed within the outer shaft. The inner shaft has a cutting edge at the distal end and extends out of the outer shaft at the proximal end, terminating in a spring-loaded push button. A lateral notch is formed in the inner shaft proximal of the cutting edge. The spring forces the inner shaft rearwardly so as to pull the notch within the outer shaft. By gripping the handle and placing pressure on the push button, the inner shaft is moved forward so as to expose the notch. A suture may then be placed in the notch so that the instrument grips the suture between the outer shaft and the inner shaft when the push button is released. The instrument is used for suturing muscle at an incision by gripping the end of a suture, forcing the distal end of the instrument beneath the epidermis within an incision, into the fatty tissue and through the muscle adjacent one side of the incision to force the suture through the muscle.
