WiseTek

What WiseTek does

WiseTek, legally Ningbo Zhiguang Electromechanical Technology Co., Ltd. (宁波智光机电科技有限公司) and branded as 智光科技 / Zhiguang Technology, is a privately held Chinese medical device company that designs and manufactures single-use (disposable) flexible endoscopes and the reusable image processor that drives them. Operating from Ningbo, Zhejiang with a stated presence in Silicon Valley, the company focuses on minimally invasive visualization in three clinical specialties — urology (single-use ureteroscope), cystology (single-use cystoscope), and pulmonology (single-use electronic bronchoscope) — under the OTU product family, with the OTU-A series medical endoscope image processor serving as the reusable platform console.

The company's core technology is a vertically integrated single-use endoscope platform that spans in-house design and manufacturing of core optoelectronic components (including a patented light source and patented bullet-shaped head tip, utility model patent ZL 2016 2 1263126.9), precision parts, and final system assembly. The disposable ureteroscope weighs 185 g and supports up to 275° deflection with a self-locking angle and a 3.6 Fr working channel; the cystoscope supports up to 210° bidirectional deflection with a 6.6 Fr working channel; the bronchoscope supports up to 180° bidirectional deflection. The OTU-A processor (2.7 kg, AC 220V/50Hz, HDMI/CVBS/USB outputs) is designed to pair exclusively with WiseTek's disposable catheters, producing a closed hardware ecosystem.

Commercially, WiseTek runs a sales-led go-to-market targeting hospitals and surgical centers, with quote-based pricing directed through a dedicated sales email and phone line. The business model is a classic razor-and-blade: one-time capital placement of the OTU-A console per facility followed by recurring per-procedure consumption of disposable catheters (each procedure consumes one sterile single-use catheter). The company's only disclosed institutional capital event is a $437,701 seed round from 6 Dimensions Capital in August 2018, and it has positioned itself in regional standards-setting by drafting the "Zhejiang Made" group standard for disposable ureteroscopes (public consultation August–September 2024).

Revenue model

1. Single-use endoscope catheter sales: Sale of disposable ureteroscope, cystoscope, and bronchoscope catheters sold as single-use sterile devices to hospitals and surgical centers. Each procedure consumes one catheter, generating recurring per-procedure revenue tied to surgical volumes.
2. OTU-A Series Image Processor capital sales: Capital sale of the OTU-A series medical endoscope image processor (the reusable console) sold to facilities alongside disposable catheters; functions as the anchor hardware enabling recurring catheter consumption.

Core offering

WiseTek designs, manufactures, and sells single-use flexible endoscope catheters (disposable ureteroscope, cystoscope, and electronic bronchoscope) that pair with its proprietary OTU-A Series Medical Endoscope Image Processor. The catheters are sterile, single-procedure devices used for minimally invasive urological and airway visualization in hospitals and surgical centers, while the OTU-A console is a reusable capital equipment component that processes and outputs images from the disposable catheters.

Product overview

WiseTek (智光科技) operates as a platform medical device company with a leading position in the single-use urological endoscope segment, organized as a core platform-plus-modules architecture. The OTU-A Series Endoscope Image Processor (内窥镜图像处理器) is the core reusable hardware platform that processes and outputs endoscopic images, and it must be paired with WiseTek's line of single-use visualization modules: the Disposable Ureteroscope Catheter (一次性使用输尿管内窥镜导管), the Disposable Cystoscope Catheter (一次性使用膀胱内窥镜导管), and the Disposable Electronic Bronchoscope (一次性使用电子支气管内窥镜). The company is one of very few worldwide to have vertically integrated the supply chain for single-use endoscopes, covering independent R&D and manufacturing of core optoelectronic components, precision parts, and final system assembly.

Emerging players

• Neptune Medical: Neptune Medical is a venture-backed developer of single-use and robotic endoscopy platforms targeting GI and adjacent indications. It is an emerging peer pursuing a similar disposable-plus-console architecture, useful as a comparable for WiseTek's vertical-integration playbook.
• UroViu Corporation: UroViu is an early-stage company developing single-use flexible cystoscopes and ureteroscopes that pair with a portable reusable handle/display. It is a direct emerging peer in the single-use urology endoscopy segment where WiseTek is most differentiated.

Direct peers

• Cook Medical: Cook Medical manufactures ureteroscopes, cystoscopes, and accessory devices used in urology and pulmonology procedures. Its single-use and limited-use flexible scopes directly overlap with WiseTek's catheter portfolio and target the same surgical-center buyer.
• Ambu: Ambu is the global pioneer in single-use endoscopes, with the aScope family covering bronchoscopy, urology, and cystoscopy indications. It is the most directly comparable competitor to WiseTek's disposable catheter-plus-reusable-console platform and targets the same hospital buyer.
• Coloplast: Coloplast's interventional urology division sells single-use and reusable ureteroscopes and accessories globally. It is a direct comparable in the disposable ureteroscope segment and shares WiseTek's hospital-channel GTM in urology.

Broad incumbents

• Stryker: Stryker operates across multiple endoscopy-adjacent surgical device categories including urology, ENT, and pulmonology visualization. It is a broad incumbent whose scale and integrated OR sales motion make it a relevant comparable for WiseTek's multi-indication platform strategy.
• Karl Storz: Karl Storz is a leading endoscopy system manufacturer offering flexible and rigid ureteroscopes, cystoscopes, and bronchoscopes paired with proprietary camera/light consoles. It overlaps directly with WiseTek's three disposable catheter indications and reusable OTU-A console architecture.
• Hologic: Hologic sells single-use hysteroscopes and other disposable visualization systems, and has built hospital-channel expertise around single-use endoscopy conversion. It represents a broader incumbent pursuing adjacent single-use endoscope categories that overlap with WiseTek's platform-plus-modules approach.
• Boston Scientific: Boston Scientific markets the LithoVue single-use digital flexible ureteroscope, a direct competitor to WiseTek's disposable ureteroscope, and also serves urology and pulmonary through its broader endoscopy and urology portfolios. It is a much larger incumbent with established hospital sales channels and clinical evidence.
• Olympus: Olympus is the dominant global endoscope manufacturer across reusable and emerging single-use categories, with strong KOL relationships and full procedure-room integration. It competes with WiseTek across ureteroscopy, cystoscopy, and bronchoscopy and sets the clinical-evidence bar for hospital procurement.
