The diseases of women : a handbook for students and practitioners . l: this cutting edge, shaped like the pointof a quill pen, is ensheathed in a sliding barrel moved bya mounted thumb-piece, so that it can be protected at thewish of the operator. On the sides of the instrument thereare two spring hooks for retaining the instrument in posi-tion after its point has penetrated the cyst-wall. The trocar 387 388 DISEASES OF WOMEN. is fitted to a metre and a half (about five feet) of india-rubber tubing. The mechanism of this complicated instru-ment should be carefully studied by those proposing to useit. These trocars are very clumsy, and unless in constantuse work stiffly and easily get out of order (Figs. 109 andno). Pedicle-needle.—This instrument is designed to carry theligature through the pedicle of the tumor. The stem ofthe needle is about 15 cm. long, and is composed of nickeledsteel adjusted to a metal handle (Fig. ill). The stem iscurved toward the end, which should be bluntly the free end it is perforated by two holes, one behind. Fig. iio.—Ovariotomy trocar with its point guarded. the other; each should be capable of easily accommodatingthe thickest ligature silk. As a matter of fact, any needle capable of carrying theligature will serve the purpose of a pedicle-needle, but theneedle represented possesses many advantages which anoperator will realize as soon as he begins to acquireexperience. Sponge-holders.— Sponges on sticks are undesirablein abdominal operations. It is useful to employ instrumentsin which sponges or cotton-wool or gauze dabs can be easilymounted. A useful form of holder is shown in Fig. is an ovum forceps: the opposed sides of the fenestratedblades are devoid of serrations. The handles are furnishedwith clips. These holders can be put to many useful pur-poses besides holding sponges : they are easily sterilized.
