Description

Technical Field

[0001] This invention relates to the field of endoscopic instruments, specifically a disposable endoscope. Background Technology

[0002] Endoscopes, as compact optical instruments, are widely used in the medical and industrial fields. In the medical field, endoscopes are mainly used to enter the human body through natural orifices or small incisions to perform medical examinations and assist doctors in diagnosing and treating diseases. An endoscope generally consists of a head end equipped with a camera module, a light source, and a PCB board; a processing system for image processing and display; and a connecting part that connects the head end to the processing system. Because endoscopes perform invasive examinations, especially the invasive head end, the smaller its size, the more convenient the invasive examination.

[0003] Existing endoscopes are relatively large due to the multiple electrical components stacked inside. Furthermore, endoscopes may generate an electrostatic field during use, which could damage the electrical components and consequently the endoscope. Summary of the Invention

[0004] The present invention aims to provide a disposable endoscope that can reduce size and provide electrostatic protection, thereby improving the practicality and safety of the endoscope.

[0005] This invention provides the following basic solution: a disposable endoscope, comprising: a headstock;

[0006] The top surface of the head end is provided with mounting holes and copper pin holes; inside the head end, from one end of the top surface to the opening end, are arranged in sequence: camera module, PCB and RFPCB;

[0007] The camera module is positioned opposite the mounting hole, the bottom surface of the camera module is fixedly connected to the top surface of the PCB, and LED lights are also provided on both sides of the camera module on the top surface of the PCB.

[0008] The bottom surface of the PCB is T-welded to one side of the RFPCB, and the RFPCB is vertically mounted on the bottom surface of the PCB.

[0009] The PCB has through holes opposite to the copper pin holes, and copper pins are installed inside the copper pin holes, with the copper pins passing through the through holes.

[0010] Note: PCB: Printed Circuit Board;

[0011] RFPCB: Flexible Printed Circuit Board.

[0012] Beneficial effects of the basic solution: The endoscope headstock (i.e., the head end) in this solution is equipped with the necessary electrical components: camera module, PCB, RFPCB, and LED light. The camera module and LED light are located on the top surface of the PCB, and the camera module is positioned opposite the mounting holes on the top surface of the headstock to enable image acquisition. The RFPCB is located on the bottom surface of the PCB and is T-welded to the PCB, making the PCB perpendicular to the RFPCB. This reduces the lateral dimension, making the overall headstock smaller and creating a smaller headstock size. This makes the endoscope easier to use for invasive examinations and improves its practicality.

[0013] Meanwhile, copper pin holes are provided on the top surface of the headstock, and through holes are provided on the PCB opposite to the copper pin holes. Copper pins are placed in the copper pin holes and pass through the through holes, so that the copper pins go from the headstock to the side of the RFPCB to provide electrostatic protection for the electrical components in the headstock and conduct static electricity through the copper pins; in particular, the copper pins pass through the through holes and are parallel to the side of the RFPCB, which also adds ESD (electrostatic discharge) protection to the RFPCB; the setting of copper pins can provide electrostatic protection, so that the endoscope meets the high level of ESD requirements and improves the safety of the endoscope.

[0014] In addition, the connection structure between the electrical components is simple, the overall structure is also simple, and the installation is convenient, which can effectively improve production efficiency.

[0015] In summary, this solution reduces size, facilitates installation, and provides electrostatic protection, thereby improving the practicality, safety, and production efficiency of endoscopes.

[0016] Furthermore, adhesive is applied to the copper needle inside the copper needle hole on the top surface of the head end seat.

[0017] Beneficial effect: Applying adhesive to the copper needle hole on the top surface of the head end seat fixes it in place and prevents the copper needle from moving.

[0018] Furthermore, a clamping opening is also provided on the top surface of the head end seat;

[0019] The PCB is crescent-shaped, with its notch facing the jaws.

[0020] Beneficial effects: When using an endoscope, because the RFPCB is vertically mounted on the bottom surface of the PCB and the PCB is crescent-shaped, its notch is aligned with the forceps channel provided on the top surface of the headstock, so that operating tools such as forceps can be operated through the PCB and the headstock.

[0021] Furthermore, the copper needle holes are located on both sides of the clamp opening;

[0022] The through-holes are located at the two tips of the PCB, opposite to the copper pinholes.

[0023] Beneficial effect: The through-holes are set at the two tips of the PCB, opposite the copper pin holes. After the copper pins are inserted, the original layout of the PCB and RFPCB is not affected.

[0024] Furthermore, the camera module and LED lights are connected to the PCB using ultra-low temperature solder paste for low-temperature baking.

[0025] Beneficial effects: The PCB uses ultra-low temperature solder paste and is baked at low temperature, which can ensure the perpendicularity of the LED and the camera module, making subsequent installation easier.

[0026] Furthermore, a heat-conducting block is provided between the LED and the PCB to elevate the LED.

[0027] Beneficial effects: The LED light uses a heat-conducting block to elevate the light source, realizing an LED cold light source system that replaces the traditional fiber optic cold light source, resulting in better lighting effects.

[0028] Furthermore, the camera module includes: a sensor and a lens;

[0029] The lens is positioned in the non-imaging area of ​​the sensor.

[0030] Note: sensor: image sensor;

[0031] lens: lens.

[0032] Beneficial effects: The camera module adopts the process of directly packaging the lens with the CMOS sensor, which makes the non-imaging area of ​​the sensor a support to fit the lens, so that the sensor and lens become a whole, which is conducive to mass production and improves the yield rate.

[0033] Furthermore, the lens is fixed to the inner wall of the mounting hole by applying adhesive around its perimeter.

[0034] Beneficial effect: The lens is fixed to the inner wall of the mounting hole by applying adhesive around the perimeter, without overflowing the surface, thus securing the lens.

[0035] Furthermore, a connector is provided on the side of the RFPCB at the end furthest from the head end.

[0036] Beneficial effect: Connecting the RFPCB to other external systems is achieved through connectors. Attached Figure Description

[0041] The following detailed description illustrates the specific implementation method:

[0042] The reference numerals in the accompanying drawings include: head end base 1, mounting hole 2, copper pin hole 3, clamping mouth 4, camera module 5, PCB 6, RFPCB 7, LED light 8, sensor 9, lens 10, non-imaging area 11, solder ball 12, heat-conducting block 13, copper pin 14, connector 15, fixing plate 16, mounting through hole 17, positioning hole 18, connecting block 19.

[0043] In the description of this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" refers to two or more; the terms "connected," "fixed," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0044] In the description of this specification, it should be understood that the directional terms such as "upper," "lower," "left," and "right" used in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should also be understood that when it is mentioned that one element is connected to another element "upper," "lower," "left," or "right," it can be directly connected to the other element "upper," "lower," "left," or "right," or indirectly connected to the other element "upper," "lower," "left," or "right" through an intermediate element.

[0045] The basic implementation examples are as follows: Figure 1 As shown:

[0046] A disposable endoscope includes: a headstock 1; in this embodiment, the headstock 1 is shaped like a cylindrical cover.

[0047] The top surface of the head end seat 1 is provided with mounting holes 2, copper needle holes 3, and clamping grooves 4;

[0048] From one end of the top surface to the one end of the opening, the following components are arranged sequentially inside the head end 1: camera module 5, PCB 6 and RFPCB 7;

[0049] The camera module 5 is positioned opposite to the mounting hole 2. The bottom surface of the camera module 5 is fixedly connected to the top surface of the PCB 6, and LED lights 8 are also provided on both sides of the camera module 5 on the top surface of the PCB 6. Ultra-low temperature solder paste is used between the camera module 5, the LED lights 8 and the PCB 6 for low-temperature baking connection. The ultra-low temperature solder paste and the low-temperature baking temperature are 180 degrees. If low-temperature silver paste is used, the ultra-low temperature solder paste and the low-temperature baking temperature can be 80 degrees, thereby reducing the impact of high-temperature displacement on the lens.

[0050] Specifically, mounting hole 2 is a square hole, and clamping mouth 4 is a round opening. Mounting hole 2 and clamping mouth 4 are set together. Copper needle holes 3 are set on both sides of clamping mouth 4. PCB6 is crescent-shaped, and its notch is opposite to clamping mouth 4. When using an endoscope, because RFPCB7 is vertically set on the bottom surface of PCB6, and PCB6 is crescent-shaped, its notch is opposite to clamping mouth 4 set on the top surface of headstock 1, so that pliers and other operating tools can be operated through PCB6 and headstock 1. Furthermore, part of the top surface of headstock 1 is inclined, and the inclined part covers half of clamping mouth 4, which makes it easier to operate the tools.

[0051] Camera module 5, such as Figure 2 As shown, it includes: Sensor 9 and lens 10; lens 10 is set on the non-imaging region 11 of Sensor 9, as shown. Figure 3 As shown, the camera module 5 uses a process of directly packaging the lens with the CMOS Sensor 9. This allows the non-imaging area 11 of the Sensor 9 to serve as a support for the lens 10, making the Sensor 9 and lens 10 a single unit. This facilitates mass production and improves yield. Solder balls 12 are provided on the bottom surface (center of the shape) of the Sensor 9 for soldering, using ultra-low temperature solder paste for low-temperature baking connection. A heat-conducting block 13 is provided between the LED and the PCB 6 to elevate the LED. The bottom surface of the heat-conducting block 13 and the top surface of the PCB 6 are connected using ultra-low temperature solder paste for low-temperature baking connection. Furthermore, the mounting hole 2 is a square hole adapted to the lens 10. The lens 10 is fixed to the inner wall of the mounting hole 2 by applying adhesive around its perimeter, ensuring it does not overflow the surface (top surface) of the head end 1.

[0052] The bottom surface of PCB6 is T-welded to one side of RFPCB7. RFPCB7 is vertically mounted on the bottom surface of PCB6, and the notch of PCB6 is on one side of RFPCB7. RFPCB7 and the notch do not coincide.

[0053] The PCB6 has through holes opposite to the copper pin holes 3. Specifically, the through holes are located at the two tips of the PCB6, opposite to the copper pin holes 3. Copper pins 14 are installed inside the copper pin holes 3, and the copper pins 14 pass through the through holes and are parallel to the side of the RFPCB7. The copper pins 14 extend from the head end seat 1 to the side of the RFPCB7 to provide electrostatic protection for the electrical components inside the head end seat 1 and to conduct static electricity. In addition, glue is applied to the copper pins 14 inside the copper pin holes 3 on the top surface of the head end seat 1 to fix the copper pins 14 and prevent them from moving.

[0054] A connector 15 is provided on the side of the RFPCB7 away from the head end, through which the RFPCB7 is connected to other external systems; in this embodiment, the connector 15 adopts Molex 5050701222, and the other system connected is a handle, and the setting of the connector 15 facilitates the connection of the handle.

[0055] In addition, during actual use, a sleeve is also attached to the open end of the head end seat 1 to protect the part of the RFPCB7 located outside the head end seat 1; in this embodiment, the sleeve is made of steel pipe.

[0056] In this design, the endoscope headstock 1 is equipped with the necessary electrical components: camera module 5, PCB 6, RFPCB 7, and LED light 8. The camera module 5 and LED light 8 are located on the top surface of PCB 6, and the camera module 5 is positioned opposite the mounting hole 2 on the top surface of the headstock 1 to enable image acquisition. The RFPCB 7 is located on the bottom surface of PCB 6 and is T-welded to PCB 6, making PCB 6 perpendicular to RFPCB 7. This reduces the lateral dimension, making the overall headstock 1 smaller and thus creating a smaller headstock 1. This makes the endoscope more suitable for invasive examinations and improves its practicality.

[0057] Meanwhile, a copper pin hole 3 is provided on the top surface of the headstock 1, and a through hole is provided on the PCB 6 opposite to the copper pin hole 3. A copper pin 14 is provided in the copper pin hole 3 and passes through the through hole. Thus, the copper pin 14 extends from the headstock 1 to the side of the RFPCB 7, providing electrostatic protection for the electrical components in the headstock 1 and conducting static electricity through the copper pin 14. In particular, the copper pin 14 passes through the through hole and is parallel to the side of the RFPCB 7, which also increases ESD (electrostatic discharge) protection for the RFPCB 7. The setting of the copper pin 14 can provide electrostatic protection, making the endoscope meet the high-level ESD requirements and improving the safety of the endoscope. In addition, the connection structure between the various electrical components is simple, the overall structure is also simple, and the installation is convenient, which can effectively improve production efficiency.

[0058] Example 2

[0059] This embodiment is basically the same as the above embodiment, except that: Figure 4 As shown, a fixing plate 16 is provided on the outer periphery of PCB6. The fixing plate 16 is provided with mounting through holes 17 and several positioning holes 18. Several connecting blocks 19 are provided on the outer periphery of PCB6. The other end of the connecting block 19 is fixedly connected to the inner periphery of the mounting through hole 17.

[0060] The positioning hole 18 is located on the extension line of the diagonal of the mounting through hole 17 and does not coincide with the mounting through hole 17. In this embodiment, there are two positioning holes 18, which are located on the two opposite corners of the fixing plate 16, so as to achieve stable positioning. In other embodiments, different numbers of positioning holes 18 can be set according to the requirements.

[0061] The number of connecting blocks 19 is 3, and they are evenly spaced to better ensure the stability and smoothness of the connection between PCB6 and fixing plate 16; in other embodiments, the number of connecting blocks 19 can also be set according to stability requirements.

[0062] The fixing plate 16 enlarges the external dimensions of PCB6, facilitating the installation and soldering of RFPCB7. The fixing plate 16 has several positioning holes 18, which allow PCB6 to be positioned during its own installation and the soldering of RFPCB7. PCB6 is housed within mounting through-holes 17 on the fixing plate 16 and is fixedly connected to the inner circumference of these holes 17 via connecting blocks 19 on its outer periphery. After T-welding, the connecting blocks 19 serving as connection points are removed, allowing the fixing plate 16 to be separated. This solves the problem of increasingly difficult T-welding due to the decreasing size of PCB6, facilitating T-welding and effectively improving the efficiency and yield of T-welding between PCB6 and RFPCB7. Furthermore, for components such as the camera module 5 and LED lights 8, these components can be installed first, followed by the separation of the fixing plate 16.
