Abstract

The present invention relates to a handheld biopsy device for collecting soft tissue samples from surgical patients. At least one electrode is provided, eg, between the handle and the tip of the biopsy device. Electrodes may be provided on the sleeve. The sleeve with the electrodes can be releasably supported on the biopsy device.

Description

technical field [0001] The present invention generally relates to devices and methods for harvesting soft tissue. More specifically, the present invention relates to a device and method for enhancing tissue coagulation using a biopsy device for harvesting soft tissue. Background technique [0002] The diagnosis and treatment of patients with malignancy, premalignant symptoms, and other diseases has long been a research hotspot. Noninvasive methods of examination of tissue include palpation, x-rays, magnetic resonance imaging, computed tomography, and ultrasound imaging. When clinicians suspect tissue may contain cancer cells, a biopsy is done through an open or percutaneous procedure. An open procedure is when the doctor uses a scalpel to make a large incision in the tissue to allow direct visualization and access to the target tissue mass. Then, the entire mass of tissue (excisional biopsy) or part of it (excisional biopsy) is removed. A percutaneous biopsy is the use o...
