Abstract

Objective: To evaluate new techniques and improvements in surgical instruments related to intestinal anastomosis procedures. Methods: A search was conducted on the free database of patents from the National Institute of Industrial Patent Office (INPI) and The United States Patent and Trademark Office (USPTO). Were analyzed all occurrences between 2012 and 2016 related to experimental surgery and intestinal anastomosis. The requests for patents were examined individually and the data collected was the nationality of the applicant, if was physical (PP) or legal (LP) person and if was innovation or invention. At the end, a comparative analysis between the two institutions was performed. Results: In INPI was found only 5 occurrences. All of them were deposited by legal entity and were inventions. In addition, only one was a national request. In USPTO database, 65 occurrences met the inclusion criteria. Of these, 48 were national applications and only 5 were filed by physical person. Conclusion: More requests were found in US database, predominating national trustee and greater solicitation to inventions than Brazilian database. The main applications for patents are invention of surgical instruments, the development of new biological glues and improvement of mechanical sutures.  Keywords: patents, gastroenterology, surgical anastomosis.

Highlights

Intestinal anastomosis has always been a great challenge for surgeons because of its potential mortality and its many complications
The objective of this study was to perform a survey of all new techniques and improvements in surgical instruments since 2012 on the free database of patents from the National Institute of Industrial Patent Office (INPI) [6] and The United States Patent and Trademark Office (USPTO) [7] and perform a comparative analysis between the two institutions
This study consists in a bibliographic analysis of exploratory study with a quantitative approach [8]. It was conducted by the international data network, using national (INPI) and international (USPTO) free databases, which were analyzed all occurrences from 2012 to 2016 related to experimental surgery and intestinal anastomosis

Summary

Introduction

Intestinal anastomosis has always been a great challenge for surgeons because of its potential mortality and its many complications. The objective of this study was to perform a survey of all new techniques and improvements in surgical instruments since 2012 on the free database of patents from the National Institute of Industrial Patent Office (INPI) [6] and The United States Patent and Trademark Office (USPTO) [7] and perform a comparative analysis between the two institutions. In the national database, the search denominator used were the words "experimental surgery", but due to the insignificant results, it was decided to change the denominator for "anastomosis" obtaining a larger number of occurrences. In USPTO, was used the word "anastomosis" and due to the high volume of requests, there was a need to refine the search using different denominators as "surgery", "experimental", "intestine", "suture" and "devices"
