Description

Technical Field

[0001] The present invention relates to the technical field of endoscopes, and particularly relates to a multi-channel insertion part for an endoscope. Background Art

[0002] As an important medical diagnosis and treatment tool, an endoscope is widely used in the examination of human body cavities such as the digestive tract, respiratory tract, and urinary tract, as well as minimally invasive surgeries. An endoscope is a detection instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, software, etc., and has an image sensor, an optical lens, a light source illumination, a mechanical device, etc. It can enter the stomach through the oral cavity or enter the body through other natural orifices. With the endoscope, lesions that cannot be shown by X-rays can be seen, so it is very useful for doctors. For example, with the help of an endoscope, a doctor can observe ulcers or tumors in the stomach and thus formulate the best treatment plan.

[0003] However, currently, the traditional endoscope insertion part usually has only one channel, which brings many inconveniences in actual operation. When performing operations such as stone extraction, the optical fiber needs to be pushed out first before the instrument can be inserted. This not only increases the operation steps but also may lead to an extended operation time, increasing the pain and risk for the patient. In addition, the traditional endoscope also requires a sheath for water inlet and outlet, further increasing the complexity and cumbersome degree of the operation, prone to operation errors, and affecting the smooth progress of the surgery. Summary of the Invention

[0004] In view of the problems that the traditional endoscope insertion part usually has only one channel, which brings many inconveniences in actual operation. When performing operations such as stone extraction, the optical fiber needs to be pushed out first before the instrument can be inserted. This not only increases the operation steps but also may lead to an extended operation time, increasing the pain and risk for the patient. In addition, the traditional endoscope also requires a sheath for water inlet and outlet, further increasing the complexity and cumbersome degree of the operation, prone to operation errors, and affecting the smooth progress of the surgery, the present invention is proposed.

And three groups of return water channels 6 are provided on the surface of the connection cylinder 5, and the return water channels 6 communicate with the inner cavity of the connection cylinder 5.

[0028] The inner cavity of the insertion part 7 is provided with an instrument group 11, and one end of the instrument group 11 penetrates through the connection cylinder 5 and the instrument communication groove 17 and extends to the inside of the instrument channel 3. The inner cavity of the insertion part 7 is also provided with an optical fiber group 10, and one end of the optical fiber group 10 penetrates through the connection cylinder 5 and the optical fiber communication groove 18 and extends to the inside of the optical fiber channel 4. The optical fiber group 10 is responsible for transmitting the light source to the tip cap body 1 of the endoscope to illuminate the examination area inside the human body.

[0029] Three groups of return water communication ports 12 are arranged on the surface of the insertion part 7 near one end of the connection cylinder 5, and the three groups of return water communication ports 12 correspond to the three groups of return water channels 6 on the connection cylinder 5 one by one, which is convenient for discharging the flushing liquid and other liquids generated during the operation, such as blood, tissue fluid, etc. out of the body, so as to keep the surgical field of view clear and ensure the smooth progress of the operation.

[0030] A lens channel 2 is arranged at the top of the tip cap body 1 near one side of the connection cylinder 5, and the lens channel 2 penetrates through the tip cap body 1. A lens wire 8 is arranged in the inner cavity of the insertion part 7, and one end of the lens wire 8 extends to the inner cavity of the connection cylinder 5. And one end of the lens wire 8 located in the inner cavity of the connection cylinder 5 is provided with a lens group 9, and one end of the lens group 9 extends to the inner cavity of the lens channel 2. The function of the lens group 9 is to clearly transmit the image inside the human body to an external display device so that the doctor can make an accurate diagnosis and treatment.

At the same time, a water return channel 6 is provided on the connection cylinder 5 for discharging waste water during the operation, keeping the surgical field of view clear. The design of three independent channels allows doctors to perform lighting, instrument operation, and liquid discharge simultaneously, without the need to frequently replace equipment or adjust the operation process, greatly improving the surgical efficiency. Compared with traditional endoscopes, when operating, the optical fiber needs to be pushed out to insert the instrument for stone extraction, and a sheath is also required for water inlet and outlet, with a cumbersome operation process and prone to errors. However, due to the three independent channels provided in the insertion part of the endoscope in this solution, doctors can more conveniently control various operations without frequently replacing instruments or adjusting equipment, thus simplifying the operation process. Moreover, the multi-channel design enables each operation during the surgical process to be independent of each other, reducing the surgical risks caused by frequently replacing instruments or adjusting equipment and improving the surgical safety.
