Neither the cutting or sharp-edged needIe, nor the so-caIIed round needle can meet these requirements. We beIieve that the needIe herein described wiI1 meet these specifications.
In the accompanying iIIustration this type of surgica1 needle is shown. It has been designed for use as a universa1 needIe and has a11 the good points of the round needIe pIus the advantages of the cutting needIe. It is especiaIIy suited for use in a11 puerperal gynecoIogica1 operations.
