Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to an endoscope button mounting structure and an endoscope. Background Art

[0002] With the development of medical technology, endoscopy technology has emerged. Endoscopes are used to visually inspect hard-to-reach locations such as organs in the human body to observe pathological conditions. It is a detection instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. It has image sensors, optical lenses, lighting sources, mechanical devices, etc. It can enter the human body cavity through natural channels to inspect cavities that communicate with the outside world (such as the digestive tract, respiratory tract, urinary tract, etc.), or it can be inserted through an incision to inspect closed body cavities (such as the chest cavity, abdominal cavity, joint cavity, etc.). Medical endoscopes have been widely used in various departments for examinations. According to the parts reached by medical endoscopes in the human body, they can be divided into otolaryngoscopes, gastroenteroscopes, ureteroscopes, arthroscopes, etc.

[0003] Traditionally, medical endoscopes consist of an inserter that inserts into the body's organs, while the handle remains external to the body and is operated by medical personnel.

[0018] In one embodiment, the mounting side is provided with a mounting hole, and the mounting hole is used to pass a connecting piece so as to connect the circuit board bracket to the endoscope housing.

[0019] In one embodiment, there are multiple first clip structures, and the multiple first clip structures are arranged at intervals along the extension direction of the circuit board mounting position; there are multiple button brackets, and the first clip structure of each button bracket is snap-fitted with each second clip structure in a one-to-one correspondence; there are multiple button bodies, and each button body is arranged in a one-to-one correspondence on the elastic part of each button bracket.

[0035] In one embodiment, see Figure 1 、 Figure 2 and Figure 3 An endoscope button mounting structure 100 includes a circuit board bracket 110, a button bracket 120, and a button body 130. The circuit board 200 has a mounting surface 111 and a mounting side 112. The mounting surface 111 is provided with a circuit board mounting position 113, and the mounting side 112 is provided with a first clamping structure 114. The button bracket 120 includes a connected elastic portion 121 and a mounting portion 122. The elastic portion 121 is arranged corresponding to the circuit board mounting position 113. The mounting portion 122 is provided with a second clamping structure 123. The first clamping structure 114 and the second clamping structure 123 are engaged with each other to maintain a distance between the elastic portion 121 and the circuit board mounting position 113. The button body 130 is provided on the elastic portion 121. The button body 130 is used to drive the elastic portion 121 to produce elastic deformation relative to the mounting portion 122 in a direction closer to the circuit board mounting position 113 under the action of an external force.

[0036] During the installation process of the endoscope button mounting structure 100, the circuit board 200 is first mounted on the circuit board mounting position 113 of the circuit board bracket 110. Then, the button body 130 is positioned on the elastic portion 121, and the button body 130 is configured to drive the elastic portion 121 to deform toward the circuit board mounting position 113. Because the first engaging structure 114 and the second engaging structure 123 engage and mate, this connection method facilitates the installation of the button body 130. The elastic portion 121 maintains a distance from the circuit board mounting position 113 of the circuit board 200. By directly pressing the button body 130, the elastic portion 121 deforms, thereby performing a touch operation on the circuit board 200. This direct pressing method is simple in structure and highly reliable, facilitating convenient operation for medical personnel.

[0037] It should be noted that the button body 130 is used to drive the elastic portion 121 to generate elastic deformation relative to the mounting portion 122 toward the circuit board mounting position 113 under the action of external force, thereby generating a touch or press operation on the circuit board 200, thereby realizing signal conversion.

[0038] Optionally, the snap-fitting manner of the first snap-fitting structure 114 and the second snap-fitting structure 123 can be: the first snap-fitting structure 114 is a slot and the second snap-fitting structure 123 is a buckle, or the first snap-fitting structure 114 is a buckle and the second snap-fitting structure 123 is a slot, or other snap-fitting manners.

[0039] Specifically, see Figure 1 and Figure 2 The first engaging structure 114 is a slot, and the second engaging structure 123 is a buckle that fits into the slot. Thus, during installation, the buckle is pressed into the slot to engage, thereby connecting the circuit board bracket 110 and the button bracket 120. This provides a simple structure and a reliable connection, thereby improving the reliability of the endoscope button mounting structure 100.

[0040] In one embodiment, see Figure 1 and Figure 3 The first engaging structure 114 includes a first boss 1141 and a second boss 1142, which are spaced apart to form a slot. Thus, the first boss 1141 and the second boss 1142 act to lock the second engaging structure 123, thereby improving the connection stability between the first engaging structure 114 and the second engaging structure 123, thereby enhancing the installation stability of the button body 130 and improving the overall usability of the endoscope button mounting structure 100.

[0041] Further, see Figure 1First boss 1141 is located on the side of second boss 1142 away from elastic portion 121. Second boss 1142 is provided with a guide slope 1143 on the side closer to first boss 1141. Guide slope 1143 is used to guide the snap into the slot. Thus, guide slope 1143 can guide the second engaging structure 123 into the slot, facilitating easier installation of button body 130 and, in turn, improving the overall installation efficiency of endoscope button mounting structure 100.

[0042] In one embodiment, see Figure 1 The first boss 1141 is located on the side of the second boss 1142 that is away from the elastic portion 121. The side of the second boss 1142 that is away from the first boss 1141 protrudes relative to the mounting surface 111. The elastic portion 121 is provided with a clearance hole 1211, and the second boss 1142 is inserted into the clearance hole 1211. The passage of the second boss 1142 through the clearance hole 1211 facilitates the smooth engagement of the clip with the slot for a secure connection, thereby improving the connection stability between the button bracket 120 and the circuit board bracket 110, and enhancing the reliability and overall quality of the endoscope button mounting structure 100.

[0043] Further, see Figure 1 The inner wall of the positioning hole 1211 is provided with a supporting block 1212. The supporting block 1212 is in contact with the second boss 1142. Thus, the supporting block 1212 and the second boss 1142 are in contact with each other, which can fix and limit the mounting portion 122, maintain the stability of the mounting portion 122, and thereby improve the connection stability between the first clamping structure 114 and the second clamping structure 123, ensure the installation stability of the button body 130, and thus improve the overall quality and reliability of the endoscope button mounting structure 100.

[0044] In one embodiment, see Figure 1 and Figure 3 The second boss 1142 is located on the side of the circuit board mounting position 113. The second boss 1142 is configured to interfere with the circuit board 200. The mounting surface 111 is provided with a limiting protrusion 1111. The limiting protrusion 1111 is located at the end of the circuit board mounting position 113 and is configured to interfere with the circuit board 200. In this manner, the second boss 1142 can limit the circuit board 200, restricting its movement toward the side of the circuit board mounting position 113 and securing the circuit board 200 to the circuit board mounting position 113 on the mounting surface 111. Furthermore, the limiting protrusion 1111 can limit the circuit board 200, preventing the end of the circuit board mounting position 113 from moving, further securing the circuit board 200 to the circuit board mounting position 113 on the mounting surface 111, and improving the installation stability of the circuit board 200.

[0045] In one embodiment, see Figure 1 A contact 131 is provided on a surface of the elastic portion 121 facing the circuit board mounting position 113. Thus, by pressing the button body 130, the contact 131 touches or presses the circuit board 200, thereby reducing the pressing stroke, improving the ease of use of the button body 130, and ensuring the efficiency of the endoscope.

[0046] In another embodiment, a contact 131 is provided on a surface of the button body 130 facing the circuit board mounting position 113. Similarly, by pressing the button body 130, the contact 131 performs a touch or press operation on the circuit board 200, thereby reducing the pressing stroke, improving the ease of use of the button body 130, and ensuring the efficiency of endoscope use.

[0047] Optionally, the mounting portion 122 and the elastic portion 121 may be connected by bonding, welding, snap connection, plug connection or other connection methods. Alternatively, the mounting portion 122 and the elastic portion 121 are an integrated structure.

[0048] Specifically, see Figure 1 and Figure 2 The mounting portion 122 and the elastic portion 121 are integrated. This provides a simple structure, facilitates production, and helps ensure the connection stability and reliability between the mounting portion 122 and the elastic portion 121, while also reducing production costs and improving economic benefits. This embodiment only provides one specific connection method between the mounting portion 122 and the elastic portion 121, but is not limited to this.

[0049] Optionally, the button body 130 and the elastic portion 121 may be connected by bonding, welding, snap connection, plug connection or other connection methods. Alternatively, the button body 130 and the elastic portion 121 are an integrated structure.

[0050] Specifically, see Figure 1 and Figure 2 The elastic portion 121 and the button body 130 are integrated. This provides a simple structure, facilitates production, and helps ensure the connection stability and reliability between the button body 130 and the elastic portion 121, while also reducing production costs and improving economic benefits. This embodiment only provides one specific connection method between the button body 130 and the elastic portion 121, but is not limited to this.

[0051] Preferably, the button body 130 , the mounting portion 122 and the elastic portion 121 are an integral injection-molded structure, which is beneficial to reducing production costs and improving overall structural stability.

[0052] In one embodiment, see Figure 1 and Figure 2The button body 130 is provided with a weight-reducing cavity. This helps to reduce the weight of the button body 130, facilitates the rebound of the elastic portion 121, increases the service life and reliability of the elastic portion 121, and further improves the overall quality of the endoscope button mounting structure 100.

[0053] In one embodiment, see Figure 1 and Figure 2 The mounting side 112 is provided with a mounting hole 1121 for receiving a connector to connect the circuit board bracket 110 to the endoscope housing. This facilitates the installation of the circuit board bracket 110 and the endoscope housing, thereby improving the overall quality of the endoscope button mounting structure 100.

[0054] In one embodiment, see Figure 1 and Figure 2 There are multiple first snap-fit structures 114, each spaced apart along the extension direction of the circuit board mounting position 113. There are multiple button brackets 120, each with its first snap-fit structure 114 corresponding to a second snap-fit structure 123. There are multiple button bodies 130, each corresponding to the elastic portion 121 of each button bracket 120. In this way, multiple button bodies 130 can be mounted on the circuit board bracket 110, allowing for different operational functions, thereby improving the ease of use of the endoscope.

[0055] In one embodiment, an endoscope (not shown) includes a circuit board 200 and the endoscope button mounting structure 100 in the above embodiments, and the circuit board 200 is disposed at the circuit board mounting position 113 .

[0056] During the installation of the endoscope, the circuit board 200 is first mounted on the circuit board mounting position 113 of the circuit board bracket 110. Then, the button body 130 is positioned on the elastic portion 121, and the button body 130 is configured to cause the elastic portion 121 to deform toward the circuit board mounting position 113. Because the first engaging structure 114 and the second engaging structure 123 engage and mate, this connection method facilitates the installation of the button body 130. The elastic portion 121 maintains a distance from the circuit board mounting position 113 of the circuit board 200. Medical personnel can directly press the button body 130 to deform the elastic portion 121, thereby performing a touch operation on the circuit board 200. This direct pressing method is simple in structure, highly reliable, and facilitates the operation of medical personnel.

[0057] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
