## About

Founded in 2014 and based in Ezhou, China, Jingwei Vision Medical Technology Co., Ltd., trading as Viestar or Biopsee, operates as a medical equipment developer focusing on the research and development, manufacturing, and application of medical devices. It has a R&D centre in Wuhan, a medical centre in Quanzhou, a sales centre in Suzhou, and a manufacturing centre in Changzhou. In 2019, the company obtained the registration certificate for confocal micro endoscope medical devices. It has cooperated with Beijing Friendship Hospital, Wuhan University Central South Hospital and other hospitals to conduct clinical research projects. In November 2025, Viestar raised over 100 million in venture funding from Efung Capital, Xi'an Huabin Fengtai Fund Management and Yangtze Optical Fibre & Cable.

The company mainly provides products of three technology areas including early tumour minimally invasive treatment technology, real-time non-invasive visualization biopsy technology, and early tumour minimally invasive treatment technology. Its confocal micro endoscopy helps clinicians to see the cell structure directly during endoscopy, thus diagnosing tumour lesions, improving the accuracy of biopsy, and reducing the rate of missed diagnosis. The company's visual biopsies can be used in respiratory, gynaecology, oncology, surgery, dentistry, and urology.

The company generates revenue by providing medical devices and services for early diagnosis and treatment of tumours.
