Description

Technical Field

[0001] This invention relates to an endoscope system, and more particularly to an endoscope system containing a reinforced connecting mechanism. Background Technology

[0002] With the development of endoscopic technology, minimally invasive surgery has gradually become widespread in various departments, such as urology, hepatobiliary surgery, and gynecology, where endoscopic minimally invasive procedures are now being performed in diagnosis and treatment. Especially with the development of electronic endoscopes, which can achieve miniaturization and flexible / rigid endoscope combinations, electronic endoscopes, particularly disposable ones, are increasingly being used in clinical applications, especially in urology and gynecology. Disposable cystoscopes, ureteroscopes, and hysteroscopes, among other electronic endoscopes, are becoming increasingly common in clinical practice.

[0003] The core difference between electronic endoscopes and traditional optical endoscopes is that electronic endoscopes place the camera module at the front of the observation position, while hardware such as the decoding board is placed at the rear via signal cables. The front-end working unit and the back-end control system are detachably connected through simple and detachable connection methods such as USB and Type-C.

[0004] Since it uses USB, Type-C and other connection methods, it is very convenient to connect and disconnect, but it can also lead to accidental loosening of the interface during clinical use. Therefore, the purpose of this application is to improve the connection method of the front end of the electronic endoscope to avoid accidental loosening of the interface during clinical use. Summary of the Invention

[0005] The endoscope system of the present invention with a reinforced connection mechanism provides a detachable reinforced connection between the working part connection end 21 and the endoscope connection mechanism 12-1 to avoid accidental loosening of the interface during clinical use.

[0006] The endoscope system with a reinforcing connection mechanism of the present invention is characterized in that: the endoscope system 100 with a reinforcing connection mechanism includes a front working part 1 and a rear control system 2, and a reinforcing connection mechanism 1-2 is provided between the front working part 1 and the rear control system 2;

[0007] A. The front working part 1 includes a working sheath 11 and a handle 12, wherein the working sheath 11 is disposed at the distal end of the handle 12;

[0008] B. The working sheath 11 is provided with an endoscope channel 11-1, an instrument channel 11-2 and a fluid channel 11-3. The endoscope channel 11-1 is provided with an endoscope working part 11-11. The proximal end of the handle 12 is provided with an endoscope connection mechanism 12-1, an instrument inlet / outlet mechanism 12-2 and a fluid inlet / outlet mechanism 12-3.

[0009] C. The back-end control system 2 includes a working part connection terminal 21, a control system 22, and a power circuit system 23;

[0010] D. During operation, the reinforcing connection mechanism 1-2 reinforces the connection between the working part connection end 21 and the endoscope connection mechanism 12-1. The endoscope working part 11-11 is connected to the control system 22 via the power circuit system 23 for real-time image display.

[0011] In clinical use, instruments such as disposable cystoscopes and disposable ureteroscopes, where the endoscope working part 11-11 is located, typically have a single-use front working part 1, requiring frequent replacement. To facilitate replacement of the front working part 1, the connection between the working part connecting end 21 and the endoscope connecting mechanism 12-1 is usually via USB, Type-C, or other easy-to-plug connection methods. Since these connection methods typically involve planar contact without significant connecting force, the connection between the working part connecting end 21 and the endoscope connecting mechanism 12-1 may accidentally loosen during clinical use due to various circumstances such as movement during operation or accidental contact by external forces. The reinforced connecting mechanism 1-2, through additional fixing action, increases the connection strength between the working part connecting end 21 and the endoscope connecting mechanism 12-1, effectively preventing accidental loosening of the interface during clinical use.

[0012] The reinforcing connection mechanism 1-2 is a detachable connection mechanism. To facilitate the replacement of the tip during use of the disposable electronic endoscope, the reinforcing connection mechanism 1-2 is typically a detachable connection mechanism.

[0013] The reinforcing connection mechanisms 1-2 are threaded reinforcing connection mechanisms, and / or concave-convex locking reinforcing connection mechanisms, and / or interference fit connection mechanisms. The applicant has only listed the above three reinforcing connection methods. In practical applications, those skilled in the art can design different specific reinforcing connection structures as needed, or combine multiple connection structures. The applicant will not provide examples of each, but none of them depart from the protection scope of this application.

[0014] Preferably, the reinforcing connection mechanism 1-2 is a concave-convex locking reinforcing connection mechanism 1-2-1; the concave-convex locking reinforcing connection mechanism 1-2-1 includes a positioning groove 1-2-11 and a positioning block 1-2-12, the positioning block 1-2-12 being embedded in the positioning groove 1-2-11 to form a reinforcing connection. In specific applications, the positioning groove 1-2-11 can be disposed on the endoscope connection mechanism 12-1, and the positioning block 1-2-12 can be disposed on the working part connection end 21; alternatively, the positioning groove 1-2-11 can be disposed on the working part connection end 21, and the positioning block 1-2-12 can be disposed on the endoscope connection mechanism 12-1; the positioning block 1-2-12 being embedded in the positioning groove 1-2-11 constitutes the reinforcing connection mechanism 1-2, firmly connecting the working part connection end 21 and the endoscope connection mechanism 12-1 together.

[0015] A sealing mechanism 12-21 is provided at the instrument entry / exit mechanism 12-2. When the endoscope system of the present invention with a reinforced connection mechanism is applied in clinical operations such as urology where fluid enters and exits body cavities, a sealing mechanism 12-21 can be provided at the instrument entry / exit mechanism 12-2. When the instrument enters or exits the instrument channel 11-2 through the instrument entry / exit mechanism 12-2, the sealing mechanism 12-21 plays a sealing role, preventing fluid from overflowing from the outlet of the instrument entry / exit mechanism 12-2 during operation.

[0016] The sealing mechanism 12-21 is detachably disposed at the instrument inlet / outlet mechanism 12-2. The sealing mechanism 12-21 can be made as an independent component and detachably connected to the proximal end of the instrument inlet / outlet mechanism 12-2 via a Luer connector or similar means. This detachable connection allows the sealing mechanism 12-21 to be replaced during use.

[0017] The sealing mechanism 12-21 is a one-way sealing valve 12-21-1. The one-way sealing valve 12-21-1 typically adopts a single-piece or multi-disc silicone valve design. With this one-way valve design, when the instrument is removed, the internal fluid or gas can reset the one-way sealing valve 12-21-1, still providing a good sealing effect.

[0018] The fluid enters and exits the body cavity through the same fluid channel 11-3. A three-way control valve 12-31 is provided at the fluid inlet / outlet mechanism 12-3, which controls the fluid's entry, exit, and containment within the body cavity. This single fluid channel design requires only one fluid inlet / outlet mechanism 12-3 on the handle 12, and the three-way control valve 12-31 controls the fluid's state, such as inlet, outlet, or complete closure. This design is very simple and does not interfere with hand movements during clinical applications.

[0019] The three-way control valve 12-31 is detachably mounted at the fluid inlet / outlet mechanism 12-3. The three-way control valve 12-31 can be made into an independent component and detachably connected to the proximal end of the fluid inlet / outlet mechanism 12-3 via a Luer connector or other means.

[0020] The handle 12 is also provided with a grip portion 12-4. The grip portion 12-4 facilitates more stable operation of the endoscope system with reinforced connection mechanism of the present invention during use.

[0021] The grip portion 12-4 includes a trigger position 12-41 and a thumb-and-finger guard 12-42. The trigger position 12-41 is typically a smooth, annular structure located at the distal end of the endoscope connection mechanism 12-1, near the endoscope connection mechanism 12-1, allowing for finger insertion. The thumb-and-finger guard 12-42 is positioned between the endoscope connection mechanism 12-1 and the instrument insertion / exit mechanism 12-2. The thumb-and-finger guard 12-42 has a smooth, inwardly arc-shaped structure, which can provide a stabilizing effect by pressing against the thumb near the web of the hand. Through the cooperation between the trigger position 12-41 and the thumb-and-finger guard 12-42, a very comfortable grip can be achieved during clinical application.

[0022] The endoscope connection mechanism 12-1, the instrument inlet / outlet mechanism 12-2, and the fluid inlet / outlet mechanism 12-3 are arranged in the same plane along the axial direction of the working sheath 11. The endoscope connection mechanism 12-1 and the fluid inlet / outlet mechanism 12-3 are usually located on the upper and lower sides of the instrument inlet / outlet mechanism 12-2. The three are arranged in the same plane along the axial direction of the working sheath 11. This arrangement in the same longitudinal plane effectively solves the problem in existing disposable endoscope systems where the inlet / outlet pipe and instrument inlet / outlet mechanism are horizontally arranged, while the endoscope connection mechanism 12-1 is vertically arranged, which leads to mutual interference between hand movements and instrument insertion / exit operations in clinical applications.

[0023] The distal centerline of the endoscope channel 11-1 forms an angle β with the centerline of the working sheath 11. Because the endoscope working section 11-11 employs an electronic endoscope design, its structure typically includes a small-sized camera module at the distal end and a flexible signal cable connected to the rear end of the camera module. Therefore, even if the endoscope channel 11-1 has bends or angles, the endoscope working section 11-11 can still be arranged along the direction of the endoscope channel 11-1. Thus, the distal centerline of the endoscope channel 11-1 and the centerline of the working sheath 11 can be set at a certain angle as needed to change the observation angle of the endoscope working section 11-11.

[0024] The β angle range is 0° to 70°. Depending on clinical needs, the β angle range is typically 0° to 70°.

[0025] The working part connecting end 21 and the endoscope connecting mechanism 12-1 are detachably connected via Type-C. Type-C connection has gradually become an internationally accepted method, offering advantages such as non-directionality and ease of insertion and removal. Of course, in practical applications, the connection between the working part connecting end 21 and the endoscope connecting mechanism 12-1 can also be via USB, gold fingers, or other connection methods. The applicant will not list all of these here, but they all fall within the scope of this application.

[0026] In clinical use, hold the working part connecting end 21 and align it with the endoscope connecting mechanism 12-1. Then continue to push the working part connecting end 21 forward. The positioning block 1-2-12 is embedded in the positioning groove 1-2-11 and locked, forming the reinforcing connecting mechanism 1-2, which further and firmly connects the working part connecting end 21 and the endoscope connecting mechanism 12-1 together.

[0027] The endoscopic system of the present invention, comprising a front working part 1 and a rear control system 2, includes a reinforcing connection mechanism 1-2 between the front working part 1 and the rear control system 2. The front working part 1 includes a working sheath 11 and a handle 12. The working sheath 11 contains an endoscope channel 11-1, an instrument channel 11-2, and a fluid channel 11-3. The endoscope working part 11-11 is located within the endoscope channel 11-1. The proximal end of the handle 12 is provided with an endoscope connection mechanism 12-1, an instrument in / out mechanism 12-2, and a fluid in / out mechanism 12-3. The rear control system 2 includes a working part connection end 21, a control system 22, and a power circuit system 23. During operation, the reinforcing connection mechanism 1-2, through additional fixing action, increases the connection strength between the working part connection end 21 and the endoscope connection mechanism 12-1, thereby effectively preventing accidental loosening of the interface during clinical practice.

[0049] Example 1: Endoscopic system of the present invention including a reinforced connection mechanism

[0050] refer to Figures 1 to 5-2 The endoscope system with a reinforcing connection mechanism in this embodiment includes a front working part 1 and a rear control system 2, and a reinforcing connection mechanism 1-2 is provided between the front working part 1 and the rear control system 2.

[0051] The front working part 1 includes a working sheath 11 and a handle 12, with the working sheath 11 disposed at the distal end of the handle 12.

[0052] refer to Figure 3 The working sheath 11 is provided with an endoscope channel 11-1, an instrument channel 11-2, and a fluid channel 11-3. In this embodiment, the distal end of the working sheath 11 is also provided with a positioning end 11-4. The instrument channel 11-2 and the fluid channel 11-3 adopt the same channel. The distal ends of the endoscope channel 11-1, the instrument channel 11-2, and the fluid channel 11-3 are fixed on the positioning end 11-4. The proximal end of the handle 12 is provided with an endoscope connection mechanism 12-1, an instrument in / out mechanism 12-2, and a fluid in / out mechanism 12-3.

[0053] refer to Figure 1 and Figure 2 The back-end control system 2 includes a working part connection terminal 21, a control system 22, and a power supply circuit system 23.

[0054] In this embodiment, the reinforcing connection mechanism 1-2 is a detachable connection mechanism, which facilitates the replacement of the front end during the use of the disposable electronic endoscope. When connected, it plays a role in strengthening and fixing, and when disassembled, the front working part 1 can be easily replaced.

[0055] refer to Figure 1-1In this embodiment, the reinforcing connection mechanism 1-2 is a concave-convex locking reinforcing connection mechanism 1-2-1; the concave-convex locking reinforcing connection mechanism 1-2-1 includes a positioning groove 1-2-11 and a positioning block 1-2-12, the positioning block 1-2-12 being embedded in the positioning groove 1-2-11 to form a reinforcing connection. The positioning block 1-2-12 is disposed on the endoscope connection mechanism 12-1, and the positioning groove 1-2-11 is disposed on the working part connection end 21. During connection, the positioning block 1-2-12 is embedded in the positioning groove 1-2-11 to form the reinforcing connection mechanism 1-2, thus firmly connecting the working part connection end 21 and the endoscope connection mechanism 12-1 together. In practical applications, the positioning block 1-2-12 can also be disposed on the working part connection end 21, and the positioning groove 1-2-11 can be disposed on the endoscope connection mechanism 12-1, without departing from the protection scope of this application.

[0056] In practical applications, the reinforcing connection mechanism 1-2 can also be a threaded reinforcing connection mechanism, and / or an interference fit connection mechanism, or different specific reinforcing connection structures designed by those skilled in the art as needed, or a combination of multiple connection structures. The applicant will not give examples here, but none of them depart from the protection scope of this application.

[0057] refer to Figure 1 and Figure 2 A sealing mechanism 12-21 is provided at the instrument entry / exit mechanism 12-2. When the endoscope system of the present invention with a reinforced connection mechanism is applied in clinical operations such as urology where fluid enters and exits body cavities, a sealing mechanism 12-21 can be provided at the instrument entry / exit mechanism 12-2. When the instrument enters or exits the instrument channel 11-2 through the instrument entry / exit mechanism 12-2, the sealing mechanism 12-21 plays a sealing role, preventing fluid from overflowing from the outlet of the instrument entry / exit mechanism 12-2 during operation.

[0058] The sealing mechanism 12-21 is detachably disposed at the instrument inlet / outlet mechanism 12-2. The sealing mechanism 12-21 can be made as an independent component and detachably connected to the proximal end of the instrument inlet / outlet mechanism 12-2 via a Luer connector or similar means. This detachable connection allows the sealing mechanism 12-21 to be replaced during use.

[0059] refer to Figure 1-2 The sealing mechanism 12-21 is a one-way sealing valve 12-21-1. The one-way sealing valve 12-21-1 typically adopts a single-piece or multi-disc silicone valve design. With this one-way valve design, when the instrument is removed, the internal fluid or gas can reset the one-way sealing valve 12-21-1, still providing a good sealing effect.

[0060] The fluid enters and exits the body cavity through the same fluid channel 11-3. A three-way control valve 12-31 is provided at the fluid inlet / outlet mechanism 12-3, which controls the fluid's entry, exit, and containment within the body cavity. This single fluid channel design requires only one fluid inlet / outlet mechanism 12-3 on the handle 12, and the three-way control valve 12-31 controls the fluid's state, such as inlet, outlet, or complete closure. This design is very simple and does not interfere with hand movements during clinical applications.

[0061] refer to Figure 2 The three-way control valve 12-31 is detachably mounted at the fluid inlet / outlet mechanism 12-3. The three-way control valve 12-31 can be made into an independent component and detachably connected to the proximal end of the fluid inlet / outlet mechanism 12-3 via a Luer connector or other means.

[0062] refer to Figure 7 and Figure 7-1 In this embodiment, the endoscope connection mechanism 12-1, the instrument inlet / outlet mechanism 12-2, and the fluid inlet / outlet mechanism 12-3 are arranged in the same plane along the axial direction of the working sheath 11. The endoscope connection mechanism 12-1 and the fluid inlet / outlet mechanism 12-3 are typically located on the upper and lower sides of the instrument inlet / outlet mechanism 12-2. The fact that all three are arranged in the same plane along the axial direction of the working sheath 11 effectively solves the problem of mutual interference between hand movements and instrument insertion / exit operations in clinical applications, which is caused by the horizontal arrangement of the inlet / outlet pipe and the instrument inlet / outlet mechanism in existing disposable endoscope systems, while the endoscope connection mechanism 12-1 is vertically arranged.

[0063] The handle 12 is also provided with a grip portion 12-4. The grip portion 12-4 facilitates more stable operation of the endoscope system with reinforced connection mechanism of the present invention during use.

[0064] refer to Figure 7 and Figure 7-1 The gripping part 12-4 includes a trigger position 12-41 and a thumb-and-finger guard 12-42. The trigger position 12-41 is typically a smooth, annular structure located at the distal end of the endoscope connection mechanism 12-1, near the endoscope connection mechanism 12-1, allowing for finger insertion. The thumb-and-finger guard 12-42 is positioned between the endoscope connection mechanism 12-1 and the instrument insertion / exit mechanism 12-2. The thumb-and-finger guard 12-42 has a smooth, inwardly arc-shaped structure, which can provide a stabilizing effect by pressing against the thumb near the web of the hand. Through the cooperation between the trigger position 12-41 and the thumb-and-finger guard 12-42, a very comfortable grip can be achieved during clinical application.

[0065] In this embodiment, the working part connecting end 21 and the endoscope connecting mechanism 12-1 are detachably connected via Type-C. Type-C connection has gradually become an internationally accepted connection method, offering advantages such as non-directionality and ease of insertion and removal. Of course, in practical applications, the connection between the working part connecting end 21 and the endoscope connecting mechanism 12-1 can also be via USB, gold fingers, or other connection methods. The applicant will not list all of these here, but they all fall within the scope of this application.

[0066] In clinical use, the working part connecting end 21 is held and aligned with the endoscope connecting mechanism 12-1. Then, the working part connecting end 21 is pushed further in, and the positioning block 1-2-12 is locked within the positioning groove 1-2-11, forming the reinforcing connecting mechanism 1-2, further and firmly connecting the working part connecting end 21 and the endoscope connecting mechanism 12-1 together. The endoscope working part 11-11 is connected to the control system 22 via the power circuit system 23 for real-time image display.

[0067] In clinical use, instruments such as disposable cystoscopes and disposable ureteroscopes, the front working part 1 of the endoscope working part 11-11 is usually for single use and therefore needs to be replaced frequently. To facilitate the replacement of the front working part 1, the connection between the working part connecting end 21 and the endoscope connecting mechanism 12-1 is usually a USB or Type-C connection method that is easy to plug and unplug. Since the contact of the above connection method is usually a planar contact without strong connection force, the connection between the working part connecting end 21 and the endoscope connecting mechanism 12-1 may be accidentally loosened during clinical use due to various situations such as back-and-forth movement during operation or accidental contact by external force.

[0068] The endoscope system with the reinforced connection mechanism in this embodiment is designed with the reinforced connection mechanism 1-2. The reinforced connection mechanism 1-2 can increase the connection between the working part connection end 21 and the endoscope connection mechanism 12-1 through additional fixing effect, thereby effectively avoiding the occurrence of accidental loosening of the interface during clinical practice.

[0069] Example 2: Observation of the endoscopic system of the present invention with an adjustable field of view and a reinforced connecting mechanism

[0070] refer to Figure 6 and Figure 6-1 The difference between this embodiment and embodiment 1 is that, in this embodiment, the observation angle of the endoscope working part 11-11 is adjustable.

[0071] In this embodiment, the distal centerline of the endoscope channel 11-1 forms an angle β with the centerline of the working sheath 11. Because the endoscope working section 11-11 adopts an electronic endoscope technology, its structure includes a small-sized camera module 11-11-1 located at the distal end and a flexible signal line 11-11-2 connected to the rear end of the camera module 11-11-1. Therefore, even if the endoscope channel 11-1 has bends or angles, the camera module 11-11-1 can still be coaxially positioned at the distal end of the endoscope channel 11-1, and the signal line 11-11-2 can be arranged along the direction of the endoscope channel 11-1. Therefore, when the distal centerline of the endoscope channel 11-1 and the centerline of the working sheath 11 are set to a certain angle as needed, the observation angle of the camera module 11-11-1 also changes with the angle of the distal end of the endoscope channel 11-1, thereby changing the observation angle of the endoscope working part 11-11.

[0072] Depending on clinical needs, the β angle range is typically 0° to 70°, with preferred clinical angles being 20°, 30°, and 70°.

[0073] It should be noted that the structures disclosed and described herein can be replaced by other structures with the same effect, and the embodiments described herein are not the only structures for implementing the present invention. Although preferred embodiments of the present invention have been described and illustrated herein, those skilled in the art will understand that these embodiments are merely illustrative, and those skilled in the art can make numerous variations, modifications, and substitutions without departing from the present invention. Therefore, the scope of protection of the present invention should be defined in accordance with the spirit and scope of the appended claims.
