STERILE DRAPE FOR ATTACHMENT TO AN IMAGING MACHINE

摘要

An embodiment of the present invention provides a kit of parts for use in a surgical procedure performed under image guidance, and particularly under real time image guidance. The kit includes a sterilized drape for use with the chosen imaging machine and which can be used to provide a sterile operating environment when the procedure is performed under the imaging beam. The kit also includes a needle holder that can keep the surgeon's hand away from the imaging beam. The needle holder is operable to hold a needle that is made from a material suitable for piercing tissue, but also substantially preserves the appearance of the needle when it is viewed under the imaging beam.

主权项

1. A needle for collecting a sample of a target tissue in a patient, comprising:
a hollow cannula configured to removably receive a stylet therein for insertion of the needle into the patient; the cannula having an open proximal end, an opposing open distal end, and a lumen extending between the open proximal end and the open distal end; the lumen defining an inner surface; the inner surface having at least one inner surface feature adjacent to the open distal end for engaging with the target tissue after removal of the stylet, and for retaining the sample during withdrawal of the cannula from the patient; the at least one inner surface feature providing a discontinuity on the inner surface.
