This page documents how medbot.cn assembles its database of China’s medical robotics companies and products. Transparency about data sourcing lets readers judge the confidence level of each field for themselves.
Source Categories
We distinguish three kinds of facts, each with its own verification bar:
1. Regulatory facts
Fields like NMPA approval status, CE marking, FDA clearance, and registration numbers. These come only from the issuing authority’s public database — never from company press releases or secondary reporting.
Primary sources:
- NMPA National Medical Products Administration (China, registration query)
- EUDAMED (European Union CE database)
- FDA 510(k) and PMA databases (United States)
Regulatory facts are not modified by automated updates and are only adjusted after a registration number or record is directly verified in the issuing database.
2. Company-stated facts
Founding year, headquarters, employee count, funding rounds, stock code, leadership, product positioning, and descriptive text. For these fields, the company itself is the authoritative source. Our role is to record what a company publicly states about itself — not to conduct independent audit.
Acceptable sources include the company’s own website, press releases distributed through wire services (PR Newswire, Businesswire, Cision, 美通社), sponsored feature articles, editorial coverage from industry publications, and published exchange filings. All are treated as equivalent for this class of fact.
Each source URL is validated at ingest time with a three-step check: (a) the link returns HTTP 200, (b) the target page’s first 500 words actually mention the company or product, (c) the domain is not on our rejection list of SEO-spam and content farms.
3. Market claims
Installation counts, market share figures, procedure volumes, and clinical trial headline numbers. We require at least two independent publishing channels for these claims, and the data is displayed alongside the reporting date and source link so readers can trace provenance.
What We Do Not Publish
- Aggregate industry statistics such as “N NMPA-approved surgical robots in China.” There is no official regulatory tally for the “medical robot” category, so any whole-industry count is a derived estimate with non-trivial error. Instead, we state what this database tracks — e.g., “This database catalogs N companies in vascular interventional robotics as of April 2026” — making the scope explicit.
- Prescriptive comparisons of safety or clinical efficacy. We are a database, not a clinical trials analysis service.
- Real-time pricing, procurement amounts, or bid data. These vary by buyer and are not reliably attributable without procurement document access.
Update Cadence
Data refresh runs monthly:
- Existing company and product records: re-scanned for updates to company-stated and market-claim fields, with the field-category rules above applied automatically.
- New entrants: NMPA Class III approvals in robotics categories over the previous month are cross-checked against our existing catalog; new companies passing a multi-source existence check are added.
- Regulatory status changes: monitored continuously; material changes (approval, revocation) are applied to the affected record when verified.
Each monthly refresh produces a git-tagged snapshot, enabling full rollback if a data error is discovered. A weekly summary of changes is maintained internally.

About Data Transparency
Every company and product detail page includes a “Sources” section listing the publicly available references used to populate the record. This enables any reader to independently verify the claims on the page. Where a factual statement lacks a cited source, treat it as derived from the listed sources collectively — not as an independent editorial claim.
