Therefore, a clip can be installed around the tumor, which can be located using a sensor. Most of the clip\u2013detectors developed thus far can only detect tumors in either the colon or stomach and require a wire to connect the clip and detector. This study designs a clip and detector that can locate a tumor in the stomach and colon. The clip contains a neodymium magnet that generates a magnetic field, and the detector includes a Colpitts oscillator that allows magnetic coupling of the clip and detector. After installing the prepared clip at the tumor location, the detector is used to locate the clip. To test the clip and detector, we conducted animal experiments, during which four clips were installed in the colon and stomach of a mini pig. We succeeded in locating the clips within 2.17 and 3.14 s in the stomach and colon, respectively, which were shorter than the detection times reported in previous studies. The demand for laparoscopic surgery and endoscopes is predicted to increase owing to this method.<\/jats:p>","DOI":"10.3390\/s22145404","type":"journal-article","created":{"date-parts":[[2022,7,21]],"date-time":"2022-07-21T03:34:40Z","timestamp":1658374480000},"page":"5404","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Clip\u2013Detector Using a Neodymium Magnet to Locate Malignant Tumors during Laparoscopic Surgery"],"prefix":"10.3390","volume":"22","author":[{"given":"Kicheol","family":"Yoon","sequence":"first","affiliation":[{"name":"Medical Devices R&D Center, Gachon University Gil Medical Center, Incheon 21565, Korea"},{"name":"Department of Biomedical Engineering, College of Medicine, Gachon University, Incheon 21565, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9714-6038","authenticated-orcid":false,"given":"Kwang Gi","family":"Kim","sequence":"additional","affiliation":[{"name":"Medical Devices R&D Center, Gachon University Gil Medical Center, Incheon 21565, Korea"},{"name":"Department of Biomedical Engineering, College of Medicine, Gachon University, Incheon 21565, Korea"},{"name":"Department of Biomedical Engineering, College of Health Science, Gachon University, Incheon 21936, Korea"},{"name":"Department of Health Sciences and Technology, Gachon Advanced Institute for Health Sciences and Technology (GAIHST), Gachon University, Incheon 21565, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun-Won","family":"Chung","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Gachon University Gil Medical Center & College of Medicine, Gachon University, Incheon 21565, Korea"},{"name":"CAIMI Co., Ltd., #206 Building of Incheon Startup Park, 204 Convensia-daero (Songdo-dong), Yeonsu-gu, Incheon 22004, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Won Suk","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Surgery, Gachon University Gil Medical Center & College of Medicine, Gachon University, Incheon 21565, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,20]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"Tumor microenvironment shapes colorectal cancer progression, metastasis, and treatment responses","volume":"9","author":"Li","year":"2022","journal-title":"Front.
