BeEndo Veterinary Endoscopy: A Decade of Persistence by Engineers, Ushering in the “Ultra-HD Era” for Small Animal Diagnosis and Treatment

In the field of veterinary medicine, endoscopy technology has long been monopolized by imported brands. Not only are the devices expensive, but their optimization for the anatomical characteristics of pets such as dogs and cats is insufficient, making it difficult for grassroots pet hospitals to carry out precise minimally invasive diagnosis and treatment. However, the engineering team of BeEndo Medical, with ten years of perseverance and innovation, has overcome multiple technical difficulties in the research and development (R&D) of veterinary endoscopes, and launched the first domestically produced high-adaptability veterinary endoscopy system. It has not only filled the technical gap of domestic veterinary endoscopes, but also enabled thousands of pets to receive precise and minimally invasive diagnosis and treatment services with its advantages of high cost-effectiveness and high adaptability, writing a new chapter in the R&D of Chinese veterinary medical equipment.

Starting from Scratch: The Engineering Team Targets the Pain Points of Veterinary Diagnosis and Treatment and Launches the Tackling Campaign “Human endoscopes cannot be directly applied to pets. The esophageal diameter of dogs, the intestinal curvature of cats, all require redesigning the mirror body parameters; moreover, in veterinary diagnosis and treatment scenarios, the portability of equipment and the simplicity of operation are also pain points that imported equipment has failed to solve.” Recalled Engineer Zhang, the person in charge of BeEndo’s veterinary endoscopy R&D team and a senior mechanical engineer. When BeEndo decided to lay out the veterinary endoscopy track in 2015, the entire industry faced a “triple dilemma”: the unit price of imported veterinary endoscopes exceeded 800,000 yuan, and more than 90% of small and medium-sized pet hospitals could not afford them; the mirror body design was based on human anatomical characteristics, which was easy to cause mucosal damage when adapted to pets; the equipment operation was complex, and the training cost for grassroots veterinarians was high and it was slow to get started.
Faced with an almost blank domestic R&D foundation, BeEndo deployed 28 core engineers from multiple fields such as optics, machinery, software, and clinical veterinary medicine to form a special R&D team. This team with an average age of 35 has since started a tackling mode of “staying in pet hospitals and immersing in laboratories”. To figure out the anatomical characteristics of pets of different breeds and sizes, the engineers traveled to 120 pet hospitals in more than 20 provinces and cities across the country, followed veterinarians to complete more than 3,000 veterinary endoscopy diagnosis and treatment surgeries, recorded everything from the esophageal length of golden retrievers to the bronchial diameter of ragdoll cats, from the respiratory rate of pets under anesthesia to the operational pain points of the mirror body during diagnosis and treatment, and accumulated more than 100,000 pieces of data and 800 research records. “Once, to observe the stress situation of endoscopic operation on cat intestines, we stayed in a pet hospital for 72 consecutive hours, recorded 15 cat gastroenteroscopy surgeries, and were still debugging the data of pressure sensors at 3 a.m.” Said Software Engineer Li. It is this extreme pursuit of details that allowed the team to accurately lock the core direction of veterinary endoscopy R&D: it is necessary to optimize the size and flexibility of the mirror body to adapt to pet anatomical characteristics, simplify the operation process, improve image clarity, and control costs to meet the needs of the grassroots market.
Tempered Through Trials: Conquering Core Technologies and Polishing “Pet-Specific” Endoscopes The R&D of veterinary endoscopes is difficult in “small and sophisticated” – it is necessary to reduce the diameter of the mirror body to adapt to the narrow cavity of pets, while ensuring image clarity and operational stability. The diameter of imported veterinary endoscopes is generally more than 8mm, while the esophageal diameter of small dogs and cats is only 5-6mm, and forced operation is easy to cause damage. For this reason, the mechanical engineer team spent 2 years carrying out hundreds of iterations on the mirror body structure: using aviation-grade lightweight alloy to build the mirror body skeleton, optimizing the traditional multi-layer cable layout into a “coaxial integration” design, and finally compressing the mirror body diameter adapted to small and medium-sized pets to 4.8mm, while ensuring that the mirror body can flexibly turn 360°, and the bending angle error is controlled within ±1°. Optical imaging is another major difficulty. There are many hairs and complex mucosal folds in the pet’s digestive tract, and imported endoscopes often have problems of blurred images and lost details. The optical engineer team, in conjunction with a top domestic optical research institute, developed a “pet-specific ultra-low-light imaging module”: improving the light transmittance in low-light environments by optimizing the lens coating process; developing an adaptive noise reduction algorithm to automatically filter imaging interference caused by hairs and mucus, and finally achieving a lesion recognition accuracy of 0.05mm level – even tiny polyps in the cat’s intestines and slight damage to the dog’s esophageal mucosa can be clearly presented. “To test the imaging stability, we put the mirror body into an environment simulating the pet’s digestive tract, bent and rubbed it more than 500,000 times to ensure that the image is free of freezes and distortion.” Introduced Optical Engineer Wang. In terms of operational adaptability, the team has also made great efforts. Aiming at the insufficient operational experience of grassroots veterinarians, software engineers redesigned the operation interface, simplified complex parameter adjustments into a “one-click mode”, added a “operation guidance prompt” function to remind doctors of the insertion depth and bending angle of the mirror body in real time; mechanical engineers optimized the grip of the control handle and adjusted the damping coefficient according to the operating habits of veterinarians, allowing novice doctors to get started quickly. After millions of durability tests and thousands of clinical trial operations, the service life of the core components of BeEndo veterinary endoscopes has reached 1.5 times that of imported products, while the operational error rate has been reduced by 60%, perfectly adapting to the special needs of veterinary diagnosis and treatment.

A Promising Future: Sustained Innovation to Benefit More Lives with Veterinary Endoscopes Today, BeEndo’s R&D team has not stopped, but has launched the R&D of the second-generation veterinary endoscopes: developing more miniaturized endoscopes for the diagnosis and treatment needs of exotic pets (such as rabbits, chinchillas, reptiles); integrating AI technology to develop an intelligent recognition system for pet digestive tract lesions, further reducing the diagnostic difficulty for grassroots doctors. “Our goal is not only to make ‘usable’ veterinary endoscopes, but also ‘easy-to-use and applicable’ ones, so that every pet can enjoy high-quality diagnosis and treatment services, and let Chinese veterinary medical equipment have more say on the global stage.” Said Engineer Zhang. From scratch, from catching up to surpassing, BeEndo’s veterinary endoscopy R&D team has broken the import monopoly with ten years of perseverance and innovation, making domestic veterinary endoscopes stand at the forefront of the industry. The efforts of these engineers are not only a technological breakthrough, but also a practice of “equality of life” – whether humans or pets, they deserve precise and safe medical protection, and they are the creators of this protection.
