Description

Technical Field

[0001] The invention relates to the field of endoscopes, and in particular to an endoscope capable of quickly dismantling and replacing pipelines. Background Art

[0002] An endoscope is a medical detection device that has an image sensor, optical lens, light source, mechanical device and other structures. It can enter the human body through the natural channels of the human body or through a small incision made during surgery.

[0003] Endoscopes in the prior art need to be disinfected before use, but the disinfection operation may be incomplete due to a malfunction of the disinfection equipment or insufficient disinfection time, which can easily cause infection. In addition, due to the severity of various infectious diseases, the disinfection requirements for endoscopes used in the respiratory system are higher, and they need to be sent to a special sterilization supply room for sterilization. The operation process is cumbersome and the cost is high. Therefore, in response to this problem, disposable endoscopes are available on the market, and their pipelines and handles are disposable. They cannot be used again after use and can only be disposed of as garbage. The handles are mostly made of plastic and cannot be degraded, causing environmental pollution.

[0004] Therefore, the prior art has defects and needs to be improved. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an endoscope with quickly detachable and replaceable pipelines, thereby solving the problem in the prior art that the endoscope needs to be disinfected before use, which has high requirements, complicated operation process and high cost; at the same time, it solves the problem of environmental pollution caused by the use of disposable handles.
