Problems solved by technology

Despite increased colon cancer screening over the past few decades, only 55% of the eligible population is screened, far from the recommended 80%, leaving millions of patients at risk
[0004] Due to a lack of adequate resources, operators performing colonoscopies often only sample the largest polyps, exposing patients to sampling bias, as smaller, less detectable polyps are often left behind, and these polyps are later detected. Colon cancer at risk of developing before colonoscopy
Due to sample bias, a negative result from a sampled polyp does not ensure that the patient is indeed cancer-free
Existing imprecise polyp removal techniques are tedious and time-consuming

Embodiment Construction

[0099] The technology proposed by the present invention is directed to an improved flexible endoscopic instrument capable of accurately and efficiently obtaining samples from single or multiple polyps and tumors in patients. In particular, the improved endoscopic instrument is capable of clearing a sample from one or more polyps and harvesting the cleared sample without having to remove the endoscopic instrument from the treatment site within the patient.

[0100] Figure 1A Shows the different types of polyps that can form in the body. Most polyps can be removed with a snare polypectomy, although exceptionally large polyps and / or sessile or flat polyps must be treated piece by piece with biopsy forceps or en bloc with endoscopic mucosal resection (EMR) resection. Recent studies have concluded that flattened sessile polyps have the highest probability of hiding malignancy at 33%. The same study has also found that non-polypoid neoplastic lesions (sessile polyps) account for...

Abstract

The present invention discloses an improved flexible endoscopic instrument that can accurately and efficiently obtain samples from Patient samples of flat polyps and multiple polyps, modified flexible endoscopic instruments can be used in conjunction with endoscopes. In one aspect, the cutting tool is coupled to a flexible torque coil configured to transfer rotational energy from the powered actuator through the length of the endoscope to the cutting tool.

Description

[0001] related application [0002] This application claims priority to provisional application US Provisional Patent Application 61 / 824,760, filed May 17, 2013, entitled "Insertable Endoscopic Instrument for Tissue Removal," It is hereby incorporated by reference into the present invention. Background technique [0003] Colon cancer is the third most common cancer and the second leading cause of death in the United States. Colon cancer arises from pre-existing colon polyps (adenomas) present in as many as 35% of the US population. Colon polyps can be benign, precancerous, or cancerous. Colonoscopy is generally recognized as an excellent screening tool for colon cancer, which has an increasing incidence worldwide. According to the literature, every 1% increase in colonoscopy screening reduces the incidence of colon cancer by 3%. Demand for colonoscopy currently outstrips the healthcare system's ability to provide adequate screening. Despite increased colon cancer screeni...
