Surgical needle description


This invention relates to surgical instruments and in particular to a novel needle holder.


The increasing perception of risk of infection of medical personnel by contact with patients body fluids has led to various measures in an attempt to reduce the likelihood of infection. There is particular concern over the possibility of transmission of hepatitis B virus (HBV) and human immuno deficiency virus (HIV) to health workers in the course of their patient care duties. In the case of surgeons and other theatre workers, needle stick injuries are relatively common and surgical gloves do not provide complete protection. In one recent study it was found that in 54% of caesarean sections, one or more glove punctures were found to have occurred to the surgeon's gloves. Attempts have been made to reduce the puncture rate, for example, by adopting a practice of double-gloving and using blunt-tipped needles. While blunt tipped needles do reduce the number of punctures, perhaps by a factor of about 1.5 the rate of puncturing is still unacceptably high.


It is, therefore, an object of the invention to provide a needle holder which, in use, is capable of reducing the risk of needle stick injury and glove puncture in surgical operations.

According to one aspect of the present invention there is provided a surgical needle holder which comprises a pair of jaws for holding a needle, while inserting stitches into tissue and retaining means associated with the jaws for retaining the tip of the needle in an inoperative position, in which the user's hand is protected from contact with the needle tip.

The retaining means may comprise an aperture, recess or groove formed in part of the jaws of the instrument, the aperture recess or groove being dimensioned to receive the needle tip. In an alternative arrangement, the jaws or the handles of the needle holder are shaped to provide abutments adapted to grip the needle tip or an elongated gap in which the needle tip can be lodged in the inoperative position.

The needle holder is preferably provided with the retaining means on opposite sides of the jaws so that the needle holder can be used either way up.

The needle holder in accordance with the invention is intended to be used with both blunt tipped and sharp needles and needles of various diameters. For this reason, the retaining means, such as a groove, when viewed in cross-section, has an inward taper.


Further features and advantages of the invention will become apparent from the following description and accompanying drawings, in which

FIG. 1 is a perspective view of a needle holder in accordance with the invention, showing the needle in the operative position,

FIG. 2 is a section along the line A--A in FIG. 1 on an enlarged scale,

FIG. 3 is a view, partly in section taken along the line B--B in FIG. 1 and again on an enlarged scale,

FIG. 4 shows a plan view of the jaws section of a second embodiment of a needle holder in accordance with the invention,

FIG. 5 shows a plan view of the jaws section of a third embodiment of a needle holder in accordance with the invention,

FIG. 6 is a plan view of a fourth embodiment in accordance with the invention, and

FIG. 7 is a view taken on the line C--C in FIG. 6.


Referring the accompanying drawings, the needle holder comprises a pair of jaws generally indicated at 1 and which can be opened and shut using the handles 2. The action of the jaws is a scissor-like action pivoted in the general region of a pivot point 3. As shown in FIG. 1 a needle 4 is held in the jaws with thread 5 attached to the needle end and the needle tip 6 used to insert stitches in conventional manner to suture the wound. The needle holder normally incorporates a ratchet-type lock schematically indicated at 17.

After inserting stitches into the wound, it is common practice for a surgeon to leave the needle locked into the jaws and to slide his hands down the instrument to grip the surgical thread and firmly close up the wound. It is at this point that it is believed that a number of glove punctures and needle stick injuries occur. In accordance with the invention, at this point in the suturing of the wound, the needle 4 is rotated in the jaws so that the needle tip 6 is received in a groove 7 in which it is releasably retained. In this position (which is indicated in FIG. 3), the needle tip is guarded within the groove and the surgeon is protected from any needle stick injury. He can therefore complete the tying of the surgical suture without risk of glove puncture. Also, when the surgeon passes the needle and needle holder to the theatre nurse, the needle should be passed in the inoperative position.

The groove 7 is formed in one or both components of the jaw 1 and in one embodiment is shaped as shown in FIG. 2 at an inwardly tapering groove. The advantage of this kind of shape is that the groove can accommodate needles of various tip sizes. The length of the groove 7 is also chosen so that it can accommodate a variety of needles of different diameter R (see FIG. 3). It may also be advantageous to provide the inner surface of the groove 7 with a milled or roughened surface for better retention of the needle tips. An inwardly tapering groove can also be used with blunt-tip needles and these are advantageously used together with the needle holder of the invention, so as to further reduce the risk of needle stick injury.

Rotation of the needle from the operative to the inoperative or parked position shown in FIG. 3 is preferably carried out using forceps to rotate the needle into the parked position. Suitable forceps for this purpose are described in UK Patent Application No. 2210574 the contents of which are hereby incorporated by reference.

A second embodiment of the invention is shown in FIG. 4. This embodiment corresponds with that shown in FIGS. 1 to 3 except that instead of a groove, one or both jaws 1 are formed with a series of holes, recesses or depressions 21. Such holes, recesses or depressions may also be inwardly tapered so as to accommodate needle tips of different sizes. Preferably, the holes or recesses 21 are formed on the face of both jaws 21 so that the needle tip can be received in an appropriate hole whichever way up the needle holder is used.

A third embodiment is shown in FIG. 5. In this embodiment, instead of providing a groove in the jaws 1 the proximal end of the jaws are modified to form a slot 31. This slot may be tapered inwardly to accommodate needle tips of different sizes.

Referring to FIGS. 6 and 7 a fourth embodiment comprises a needle holder having jaws 1 formed by a pair of handles 10 11 pivotably attached at a pivot point 12. Handle 10 includes a web-like plate 14 attached to the handle 10. Plate 14 extends into a slot formed in the handle 11 and the two handles are pivoted about a pin 12. Plate 14 has an extension in the direction of the finger grips 16. Handles 10 and 11 are so shaped in the region of the rearward plate extension 15 that when the needle holder is closed, an enlarged gap 20 or 21 exists between the arms of the handles. A ratchet closure 17 enables the needle holder to be held in a closed position without maintaining finger pressure on the handles. The inward faces of the portions of the arms 10 and 11 which form the sides of the gap 20 or 21 may be sloped inwardly so as to form inwardly tapered slots in cross-section.

In a modification of the embodiments shown in FIG. 5 or FIGS. 6 and 7 additional retaining means (e.g. a groove or recesses) may be formed in one or both faces of the jaws in the region of the pivot point. This arrangement allows needles to be accommodated which have a larger range of diameters.

Preferably, the retaining means comprise a groove or slot having a substantially uniform width. In comparison with a standard needle holder, it may be desirable to shift the pivot point forward (i.e. in the direction of the open end of the jaws), in order to provide the maximum length of available area for locating the groove and/or slot. Also, in order to be able to provide retaining means of significant width and depth, the bulk size of the needle holder in the region of the jaws may need to be increased compared with some standard or conventional needle holders.

In a more elaborate design, the needle holder may be modified by the provision of a rolling hinge. In such a modification, movement of one handle axially with respect to the other causes the needle to rotate from its operative to its inoperative position, without needing to touch the needle with forceps. Once the needle is in its inoperative position, the tip may then be urged into a retaining means such as a groove.
