Description

[Technical Field]

[0001] The present invention relates to the technical field of medical devices, and more particularly to a button mounting structure for an endoscope and an endoscope. [Background technology]

[0002] With the development of medical technology, endoscopic technology has emerged. Endoscopes are used to visually inspect hard-to-reach areas, such as organs, inside the human body to observe pathological changes. They are examination instruments that combine traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. They include image sensors, optical lenses, illumination sources, and mechanical devices. They can enter the human body via natural passages to examine passages that connect to the outside (e.g., the digestive tract, respiratory tract, and urinary tract), or can be inserted through incisions to examine enclosed body cavities (e.g., the thoracic cavity, abdominal cavity, and joint cavities). Medical endoscopes have been widely used in various medical examinations. Depending on the parts of the body they can reach, they can be divided into otolaryngoscopes, gastrointestinal endoscopes, ureteroscopes, arthroscopes, and other types.

[0003] In the prior art, the main structure of a medical endoscope is divided into an insertion tube and a handle. The insertion tube is inserted into the human body's organs, and the handle is operated by a medical professional outside the body. To meet the demands of examinations, the endoscope has more and more functions, and the corresponding function buttons have also increased. However, the installation of these buttons is complicated, unreliable, and cumbersome to operate. Summary of the Invention [Problem to be solved by the invention]

[0008] In one embodiment, the first engaging structure includes a first boss and a second boss, and the first boss and the second boss are spaced apart to form the engaging groove.

[0009] In one embodiment, the first boss is located on one side of the second boss that is farther from the elastic portion, and a lead-in slope is provided on one side of the second boss that is closer to the first boss, and the lead-in slope is used to guide the snap-fit ​​portion into the engagement groove.

[0010] In one embodiment, the first boss is located on one side of the second boss that is farther from the elastic portion, the one side of the second boss that is farther from the first boss is installed so as to protrude from the mounting surface, a retraction hole is provided in the elastic portion, and the second boss is drilled in the retraction hole.

[0011] In one embodiment, an abutment block is provided on an inner wall of the retraction hole, and the abutment block abuts against the second boss.

[0012] In one embodiment, the second boss is located on the side of the circuit board mounting position, and the second boss is used to abut against the circuit board, and the mounting surface is provided with a stopper protrusion, and the stopper protrusion is located at the end of the circuit board mounting position, and the stopper protrusion is used to abut against the circuit board.

[0013] In one embodiment, a contact point is provided on the surface of the elastic portion facing the circuit board mounting position.

[0014] In one embodiment, the button body has a contact point on a surface facing the circuit board mounting position.

[0015] In one embodiment, the mounting portion and the resilient portion are of one unitary construction.

[0016] In one embodiment, the elastic portion and the button body are integrally formed.

[0017] In one embodiment, the button body is provided with a hollowed-out chamber.

[0018] In one embodiment, the mounting side is provided with mounting holes, which are used to drill connecting members to connect the circuit board holder to the casing of an endoscope.

[0019] In one embodiment, there are a plurality of first attachment structures, and the plurality of first attachment structures are installed at intervals along the extension direction of the circuit board mounting position; there are a plurality of button holders, and the first attachment structure of each button holder corresponds one-to-one to each of the second attachment structures and is snap-fitted; there are a plurality of button bodies, and each button body is provided in one-to-one correspondence with the elastic portion of each button holder.

[0020] The endoscope includes a circuit board and any one of the above-described button mounting structures for an endoscope, and the circuit board is provided at the circuit board mounting position.

[0021] In the endoscope installation process, the circuit board is first installed at the circuit board installation position of the circuit board holder, and then the button body is attached to the elastic part, so that the button body drives the elastic part to deform toward the circuit board installation position. Because the first fastening structure is engaged with the second fastening structure, this connection method is advantageous for improving the ease of installation of the button body. The elastic part and the circuit board installation position are spaced apart, so the medical professional directly presses the button body to deform the elastic part and perform a point contact operation with the circuit board. This direct pressing method has a simple structure, is highly reliable, and is advantageous for improving the ease of operation for the medical professional. [Brief explanation of the drawings]
