Description

Technical Field

[0001] The invention relates to the technical field of endoscopes, in particular to a puncture endoscope system used on the rectum of small animals. Background Art

[0002] In the process of new drug development, before a candidate drug enters the clinical trial stage, its acute, chronic, developmental and reproductive toxicity and carcinogenicity must be fully evaluated to ensure the effectiveness and safety of the drug after administration to humans. Generally, the drug is injected into the rectum of small animals for experiments, and the experimental animals need to be dissected to confirm the symptoms. Experiments often require euthanasia of many small animals, which brings animal ethical issues. Therefore, the introduction of endoscopic examinations in animal experiments can effectively reduce the number of experimental animals.

[0003] Chinese patent document CN201620875799.3 discloses an endoscope, including a head end structure, a bending portion connected to the head end structure, an insertion tube connected to the bending portion, a handle connected to the insertion tube, and a display screen on the handle. However, when it is used for experiments on small animals such as mice, one hand is required to control the head end to maintain precise operation of the head, and the other hand is required to hold the handle and watch the display screen on the handle. It is impossible to perform other instrument operations on the small animal at the same time, and more operators are required to participate, which increases the complexity and difficulty of the work and prolongs the experiment time. The long time requires an increase in the anesthetic dose or the number of anesthesia, thereby increasing the risk of death of the small animal after anesthesia. This type of endoscope cannot be well adapted to small animal experiments, nor can it meet the needs of researchers to independently and quickly conduct small animal experiment research.

[0004] Another Chinese patent document CN202222182308.5 describes an endoscope, which, through the arrangement of external connecting parts, internal connecting tubes and nozzles, allows the endoscope to be connected to a gas source or a water source at any time, thereby achieving the purpose of flushing the camera. However, when animal endoscopic surgery is used to examine animals, blood and dirt may gush out of the affected area. In order to maintain a clear field of vision, the endoscope needs to continuously clean the camera through its water supply channel. However, its control handle is bulky and has a relatively complex structure, requiring the participation of multiple operators to complete, making the operation complicated and the efficiency too slow.
