Abstract

A surgical instrument in the form of a biopsy needle for removing tissue samples from a patient. The device has means for preloading to excise tissue samples of a preselected one of many possible tissue sample sizes. After preloading, the procedure is easily accomplished using a single hand. The tip is rendered less traumatic by positioning the distal end of the tissue sample notch relatively close to the very distal tip of the stylet. This is accomplished by grinding the distal tip of the stylet into an elliptical shape in a plane having a lateral projection which is away from the distal end of the tissue sample notch.
