Description

Technical Field

[0001] The present invention relates to the technical field related to tools for disassembling rumen fistulas in dairy cows, and particularly to a segmented cutting device and system for rumen fistulas. Background Art

[0002] In the field of dairy cow breeding and scientific research, the rumen fistula technology is widely used for real-time monitoring of the digestion process in the rumen, collecting content samples, and evaluating feed fermentation efficiency. Specifically, this technology enables operators to directly obtain rumen internal environment data by establishing an artificial fistula opening in the rumen wall of dairy cows and implanting a special fistula device, thereby providing key support for precise nutritional regulation, microbial community research, and metabolic disease diagnosis.

[0003] Currently, widely used dairy cow rumen fistulas usually adopt a special structural design with a thin middle part and thick ends, and their materials are mainly made of rigid silicone. Before installation, it is soaked in hot water to make it soft. Then, one thick end is squeezed and placed into the dairy cow's body, with the muscle layer located in the middle position. This design helps the fistula to better fit the dairy cow's body after installation, reducing adverse effects on the dairy cow's body and also facilitating the maintenance of the fistula's stability.

[0004] However, significant technical bottlenecks are faced during the disassembly or replacement of the fistula. Existing technologies mostly rely on traditional cutting tools (such as scissors) for cutting operations. Due to the limited space of the rumen opening and the dense distribution of muscle, blood vessels, and nerve tissues around the fistula, the operation vision is limited, making it difficult to precisely control the cutting range and force, and it is extremely easy to accidentally injure surrounding normal tissues, resulting in complications such as bleeding and tissue tearing, and even affecting the physiological functions of dairy cows. In addition, the material of the rumen fistula usually has high toughness and elasticity, making traditional cutting methods difficult to operate, and it is easy to cause incomplete cutting or irregular edge fractures, resulting in the retention of fistula fragments in the body, thereby triggering local inflammatory reactions and threatening the health of dairy cows.

[0005] Currently, there is no effective solution to the problems of easy accidental injury to dairy cows and irregular cutting by scissors in the related technologies. Summary of the Invention

[0006] The purpose of the present invention is to provide a segmented cutting device and system for rumen fistulas to solve the problems of easy accidental injury to dairy cows and irregular cutting by scissors in the related technologies.

[0305] The advantages of the present invention are that the cooperation between the first locking unit and the second locking unit can limit and fix the first baffle unit and the second baffle unit, ensure that the baffle maintains a stable position during cutting, and will not move or shake, thereby ensuring the cutting accuracy and safety. Through locking, the structure of the whole device is more stable, can withstand greater force during cutting, reduce the possibility of device deformation, and improve the reliability and durability of the device.
