Embodiment Construction
[0135] The technology presented herein relates to improved flexible endoscopic instruments that can precisely and efficiently obtain single and multiple polyp and tumor samples from patients. In particular, the improved endoscopic instrument enables removal of a sample from one or more polyps and removal of the removed sample without having to remove the endoscopic instrument from the treatment site within the patient.
[0136] Figure 1A Various types of polyps that can form in the body are shown. Most polyps can be removed by snare polypectomy, although particularly large polyps and / or sessile or flat polyps must be removed individually with biopsy forceps or en bloc with endoscopic mucosal resection (EMR). A recent study concluded that depressed sessile polyps had the highest rate of malignancy at 33%. The same study also found that non-polypoid neoplastic lesions (sessile polyps) accounted for 22% of patients with polyps or 10% of all patients undergoing colonoscopy. Th...

Abstract
The surgical console includes drive components, vacuum interface, fluid transfer device, user interface, and control circuitry. The drive assembly is configured to be coupled to the endoscopic tool and rotated by the motor. The vacuum port is configured to apply a vacuum to the endoscopic tool. The fluid transfer device is configured to flow fluid through the endoscopic tool. The user interface is configured to receive user input indicative of at least one of an instruction to rotate the endoscopic tool or to cause fluid to flow through the endoscopic tool when the vacuum is applied. The control circuit controls at least one of the drive assembly, the vacuum interface, or the fluid transfer device based on the instructions and is configured to cause the drive assembly to rotate the endoscopic tool while the vacuum interface applies vacuum in response to user input indicative of an instruction to rotate the endoscopic tool .
