Another object is to supply a needle holder provided with special means for gripping the instrument, which means designate the proper anatomic role to at least four fingers of the surgeons hand.

Another object is to provide a needle holder which enables a firm and nimble hold of the instrument.

Still another object is to provide a needle holder which engages more fingers than the two ring needle holders, without making the handle of the instrument more complicated.

Another object is to provide a bicapsular needle holder, the capsules of which have the indispensable length so that the ring like member will not exert any substantial pressure on the fingers.

Another object is to provide a capsular member for the forefinger, so that the latter is conveniently raised whereby the pressure of the ring like member for the thumb does not become uncomfortable over the thumbs dorsal surface.

A still further object is to provide the capsular members with an internal striated surface imitating the capillary grooves by means of fine fiutings which benefit the retention of the instrument.

.A still further object is to provide an arcuate lever for the middle finger located between the ring like member for the ring finger and the capsular member for the forefinger.

These and further objects and advantages of the invention will become apparent in the course of the following description. In order that the invention may be more clearly understood and readily carried out, a preferred embodiment thereof has been illustrated in the accompanying drawings, by way of example.

In the drawings:

Figure 1 is a perspective view of a bicapsular grip applied to a needle holder.

Figure 2 is the same needle holder as shown in Figure 1 but illustrating the position of the surgeons hand when gripping the latter.

Figure 3 is a plan view of the needle holder of Figure 1.

Figure 4 is a detail of the capsular member integral with the ring like member, for the thumb.

Figure 5 is a detail in lateral elevation of the capsular member for the forefinger.

Although reference is specially made to a needleholder it is to be understood that the bicapsular grip may be applied to other similar surgical instruments and the scope of this invention has to be interpreted along these lines.

It may be appreciated from the accompanying drawings, that the bicapsular needle holder i comprises a first branch 2 and a second branch 3, pivotally linked together by means of pivot l or the like, each branch 2 and 3 having a free end portion 2' and 3, respectively.

The other end of said branches 2 and 3 con stitute the needle holder jaws 5 and 6, which are of the known type and therefore will not be described. f

The free end portion 2' is integral with a first ring like member 1,, which ring like member l is bevelled so that the inner surface 7 thereof will, enter throughout substantially its entire length with the thumbs surface without exerting a pressure thereon.

For convenience of describing said ring like member the latter is divided into an outer portion la and an inner portion lb, by axis A. The inner portion 7b is integral with a first capsular member 8, the concavity of which is directed towards the outer portion la. Said first capsular member 8 has an outer wall 8' (see Figure 2) directed towards a second ring like member 9 integral with the free end portion 3, as will be later explained.

The inner surface 8" of the first capsular member a reproduces exactly the anatomy of the thumbs ball and it even imitates its capillary grooves by means of fine flutings it which benefits the retention of the instrument. A scale shape plate H, the concavity of which is a continuation of the concavity of the first capsular member 8, is integral with said first ring like member '5 and adjacent to the free end portion 2 and so located that the axis A is approximately an axis of symmetry therefor. Said scale shape plate I! buts against the corresponding lateral portion of the thumb and thereby decreases the pressure of the rings top edge l0 and distributes said pressure in a more uniform manner, whereby the tactile sensitivity is considerably increased. The lower portion of the first capsular member 8 is slightly curved, as may be best seen in Figure 3, so that the tip of the thumb buts thereagainst, whereby slippage of the ring like member i towards the root of the thumb is avoided.

The second capsular member 9 is also bevelled but in opposite direction as said first capsular.

member I as may be appreciated from axis B and C, respectively, so that also this second ring like member 9 has its inner surface 5 so orientated that it enters throughout its substantially full length in contact with the ring finger, as best seen in Figure 2, wherefrom it is also possible to understand that the instrument is so gripped by the hand that it contitutes a prolongation thereof, or in other words it is substantially parallel to the forearm of the surgeon.

-A second capsular member 12 (see also Figure 5) is fixed to said second branch 3, by means of a rib IS. The cavity of said second capsular member I2 is directed towards the pivot 4 and the capsular member is so shaped that said cavity is the negative of the forefingers tip, ball and part of the middle phalanx, and since the fore finger is usually slightly bent the top portion l2 of said second capsular member I2 is slightly bent backwards towards said free end 3'. The inner surface l2" of said second capsular member I2 is also provided with line flutings which benefit the retention of the instrument.

Finally the second branch 3, in the preferred embodiment, is also provided with an arcuate lever It the concavity of which is directed towards said second capsular member and which arcuate lever is projecting from said second branch 3 in substantially the same plane as said second ring like member 9.

As maybe best seen in Figure 2 the first and second-ring like members i and 9 as well as the arcuate lever 14 project laterally from the respective branches 2 and 3 so that the thumb,

the middle finger and the ring finger will holdthe instrument from the outside, whilst the second capsular member I2 is so located that the forefinger will be located on thetop of the ingees I, I I a aiereey tastier eiiettiea r the inst-r menuearn fishijai y a'pivot; ea'cnb anon fi'avi g'drregend ptrt n on the same side's! e fl l s p II I I II sai -pita enl stsshearing-nee meeiter ixe nebranchsiv tegrai" n said fr' assertion-trend "t vot; ea: eh i,- ember dserene sveiiee ring like;
