Embodiment Construction

[0048] figure 1 Surgical needle 10 is shown in a (representatively somewhat simplified) perspective view. The surgical needle 10 shows a needle body 12 as a main part. The needle body is in the shape of a helix. A needle tip 14 is formed at one end. The first end 16 of the needle body 12 is seated proximate to the needle tip 14 . The second end 18 of the needle body 12 is opposite the first end. A wire 20 extends from the second end 18 .

[0049] Thus, surgical needle 10 is shown here before or during wound closure. The needle tip 14 (on the needle body not visible here) is fixedly connected to the needle body 12 in this state.

[0050] figure 2 The surgical needle 10 according to the invention is shown in another state of use in the corresponding view. Again the body 12 of the surgical needle 10 with its first end 16 and its second end 18 can be seen. However, the needle point body 22 is separated from the needle body 12 . The thread 20 is also connected to the fir...

Abstract

The present invention relates to a surgical needle (10), which can be used to suture wounds in a medical application. More precisely, the present invention relates to a surgical needle that is connected to a thread (20) and that has a tip body (22), which bears the needle tip, and a needle body (12). The needle body (12) has a helical design and has an inner cavity. The needle body has a first end (16), which faces the tip body (22). The needle body has a second end (18), which is opposite the first end (16). The tip body (22) has a thread receptacle. The thread of the thread receptacle is fed from the first end (16) of the needle body to the second end (18) of the needle body through the cavity. The surgical needle is characterised in that the tip body is designed as a separate component, which is detachably connected to the needle body, and that the tip body has a shaft piece (24) and a connecting piece (26) and is rotationally symmetrical about an axis through the needle tip.

Description

technical field [0001] The present invention relates to surgical needles that can be used to close wounds in medical applications. Background technique [0002] Suturing wounds to facilitate wound healing is an ancient technique. There are therefore numerous variants for different applications. The doctor's typical hand tools are still needles and threads. Both are available in a wide variety and can be matched to the respective application. Finished needle / thread assemblies are also generally commercially available. [0003] European patent EP1726317B1 discloses a surgical instrument and a surgical method especially suitable for cosmetic surgery. Here, the wire is guided into the tissue in the form of a multi-turn helix and generally approximately in the form of a helix. This is accomplished with straight needles. [0004] European Patent EP1778096B1 discloses a spiral suturing instrument. This suturing instrument is conceived exclusively for use in the intervertebra...
