Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an endoscope three-way device and an endoscope thereof. Background Art

[0002] The electronic endoscope is a widely used medical device that can be inserted directly into human cavities and organ cavities for direct observation, diagnosis, and treatment. It integrates cutting-edge optical, mechanical, and electrical technologies. Currently, it generally uses a miniature CMOS sensor to image the cavity object through a tiny objective optical system onto the CMOS. The received image signal is then transmitted to an image processing system, and the processed image is finally output on a monitor for observation and diagnosis by the doctor.

[0003] In clinical use, endoscopes often need to enter the human body to remove diseased tissue from the patient's body using tools such as sampling forceps, such as cutting, clamping, or puncturing, for pathological examination. These tools are inserted through a jaw valve, a three-way assembly, and a clamp channel tube. Because tools like biopsy forceps have a rigid, approximately 10mm front end that cannot be bent, the design of the three-way assembly directly affects the comfort of inserting the forceps and the physician's operating experience, and in extreme cases, can interrupt the examination.

[0004] Currently, the inner hole of a tee is usually designed with equal diameter. When the tee is just inserted, the insertion of the clamp will be difficult due to the large angle. Therefore, the present invention proposes an endoscopic tee device and an endoscope thereof to solve the above problem. Utility Model Content

[0005] In order to overcome the defects of the prior art, the purpose of the present invention is to provide an endoscope three-way device and an endoscope thereof, so as to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the technical solution of the present invention is implemented as follows: an endoscope three-way device, comprising:

[0007] A clamp channel tee, wherein the clamp channel tee includes a section A channel, a section B channel, a section C channel, a section D channel and a section E channel;

[0008] a clamp channel valve body, the clamp channel valve body being arranged obliquely above the clamp channel tee;

[0009] A clamp channel valve body connector, which is provided between the clamp channel valve body and the section B channel of the clamp channel tee;

[0010] A tee front connector, one end of which is inserted into the D section channel and the E section channel of the clamp channel tee;

[0011] A three-way suction pipe is connected, and one end of the three-way suction pipe is inserted into the C section channel of the clamp channel three-way.

[0012] Preferably, the clamp valve body is connected to the section B channel of the clamp tee through a valve body seal and a clamp valve body joint.

[0013] Preferably, the three sections of channels B, C, and E are designed with certain angles, and the section of channel D is not designed with an angle.

[0014] According to another aspect of the present invention, an endoscope includes an operating portion and an insertion portion, wherein an endoscope three-way device is inserted into the insertion portion.

[0015] Preferably, a biopsy forceps is provided above the endoscope three-way device of the insertion portion.

[0016] The beneficial effects of the utility model are as follows: sampling forceps and the like can be inserted very comfortably, reducing the risk of clinical use and allowing doctors to perform physical examinations more comfortably; and the use of powder metallurgy and other processing methods improves the consistency of the product.
