Description

Technical Field

[0001] This utility model relates to the field of cystoscopy technology, and in particular to a cystoscope with a quickly interchangeable lens. Background Technology

[0002] In the field of urological diagnosis and treatment, the cystoscope is a core diagnostic tool, and the efficiency of its lens changing directly affects the continuity of the surgical procedure. Clinical statistics show that a single radical cystectomy for cystitis requires an average of 3 to 5 lens changes with different perspectives, and the traditional lens change process causes a cumulative intraoperative interruption of 15 to 20 minutes. With the popularization of day surgery, the need for rapid switching of minimally invasive instruments is becoming increasingly urgent, especially in the treatment of cases with multiple lesions. Frequent lens changes can prolong the operation time by more than 35% and increase the risk of infection for patients.

[0003] Currently, cystoscopes used in clinical practice mainly adopt threaded locking lens interfaces. The typical structure includes precision threads at the end of the scope body, a rubber sealing ring, and spring-loaded signal contacts. The device relies on the axial clamping force of the threaded pair to achieve sealing and electrical connection.

[0004] The existing connection structure has low replacement efficiency. Due to the use of full-circumferential thread engagement, in emergency replacement scenarios in the operating room, the operator needs to complete multiple rotations to completely separate the lens. During this process, the thread surface is easily contaminated by blood or tissue fluid. Therefore, a cystoscope body with a quick lens replacement capability is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cystoscope body with a quick-change lens, aiming to improve the problem that the operator needs to complete multiple rotations to completely separate the lens in emergency operating room scenarios due to the low replacement efficiency and the use of a full-circumferential thread engagement method.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cystoscope body with a quickly replaceable lens, comprising a cystoscope body, a flexible lens disposed on the outer wall of the cystoscope body, a fixing block fixedly connected to the outer wall of the cystoscope body, a connecting block three fixedly connected to the outer wall of the fixing block, a sliding groove provided inside the connecting block three, a telescopic block two and a spring fixedly connected to the outer wall of the fixing block, a telescopic block one slidably connected to the inner wall of the telescopic block two, a transmission block fixedly connected to the inner wall of the telescopic block one, and a limit component disposed on the inner wall of the connecting block three;

[0007] The limiting component includes a connecting seat and a limiting block. The outer wall of the connecting seat is slidably connected to the inner wall of the connecting block, and one end of the limiting block is fixedly connected to the outer wall of the connecting seat.

[0008] Furthermore, the outer wall of the limiting block is slidably connected to the inner wall of the sliding groove, and the outer wall of the transmission block is slidably connected to the inner wall of the connecting seat.

[0009] Furthermore, the outer wall of the connecting seat is fixedly connected to the inner wall of the flexible lens, and the outer wall of the fixing block is rotatably connected to the connecting block one.

[0010] Furthermore, a sealing ring is fixedly connected to the outer wall of the connecting block one, and the sealing ring one and the sealing ring two form a contact seal to prevent liquid from seeping from the outside of the mirror body into the internal circuit area.

[0011] Furthermore, a second connecting block is rotatably connected to the outer wall of the connecting seat, and the outer wall of the second connecting block is fixedly connected to the inner wall of the second sealing ring.

[0012] Furthermore, the second sealing ring is fitted with the first sealing ring, and the second sealing ring and the first sealing ring form a double sealing barrier to enhance waterproof performance.

[0013] Furthermore, a sealing ring three is fixedly connected to the outer wall of the connecting seat, and the sealing ring three forms a contact seal with the connecting block two to prevent liquid from seeping in from the gap between the hose lens and the connecting block two.

[0014] Furthermore, the sealing ring three is attached to the connecting block two, and the connecting block two is used to drive the sealing ring two to be attached to the sealing ring one.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when disassembly is required, simply press the connecting seat and rotate it to disengage the limiting block on it from the limiting of the sliding groove. With the assistance of the elastic potential energy of the spring, the connecting seat can be smoothly separated from the fixed block, and the transmission block is connected inside the connecting seat to transmit signals, ensuring that signal transmission is not affected throughout the process, effectively reducing equipment downtime and ensuring the continuity of the inspection process.

[0017] 2. In this utility model, the sealing ring three on the connecting seat can effectively block liquid from entering through the gap between the connecting seat and the connecting block three. At the same time, rotating the connecting block two can make the sealing ring two and the sealing ring one on the connecting block one fit tightly together, forming a double sealing barrier, further preventing liquid from entering the interior of the endoscope. It can adapt to the complex environment of frequent contact with body fluids during cystoscopy, avoid problems such as short circuits and damage to optical components caused by liquid seepage, extend the service life of the equipment, reduce maintenance costs, and ensure the safety and stability of the examination process.

The outer wall of the fixed block 2 is fixedly connected to the telescopic block 2 14 and the spring 15. The spring 15 pushes the connecting seat 9 outward through elastic potential energy, assisting the limiting block 10 to disengage from the locking of the sliding groove 16, and at the same time provides pre-tightening force during installation to ensure the reliability of the connection. The inner wall of the telescopic block 2 14 is slidably connected to the telescopic block 13. The inner wall of the telescopic block 13 is fixedly connected to the transmission block 12. The transmission block 12 maintains a stable connection with the internal circuit of the cystoscope body 1 to ensure reliable transmission of image and illumination signals. The inner wall of the connecting block 3 11 is provided with a limiting component.

[0028] The limiting component includes a connecting seat 9 and a limiting block 10. The outer wall of the connecting seat 9 is slidably connected to the inner wall of the connecting block 11. One end of the limiting block 10 is fixedly connected to the outer wall of the connecting seat 9. The limiting block 10 locks and unlocks the connecting seat 9 by cooperating with the slot at the end of the sliding groove 16 to prevent accidental detachment during use. The outer wall of the limiting block 10 is slidably connected to the inner wall of the sliding groove 16, and the outer wall of the transmission block 12 is slidably connected to the inner wall of the connecting seat 9.

[0029] Reference Figure 1 - Figure 6 The outer wall of the connector 9 is fixedly connected to the inner wall of the flexible lens 8. The outer wall of the fixing block 2 is rotatably connected to the first connector 3. The outer wall of the first connector 3 is fixedly connected to the first sealing ring 4. The first sealing ring 4 and the second sealing ring 5 form a contact seal to prevent liquid from seeping into the internal circuit area from the outside of the lens body. The outer wall of the connector 9 is rotatably connected to the second connector 6. The outer wall of the second connector 6 is fixedly connected to the inner wall of the second sealing ring 5. The second sealing ring 5 and the first sealing ring 4 are in contact, forming a double sealing barrier to enhance waterproof performance.

The telescopic block 13 can extend and retract inside the telescopic block 2 14, while the transmission block 12 on the telescopic block 13 maintains the stability of the signal transmission function. During this process, the spring 15 uses its own elastic potential energy to help push the connecting seat 9, so that it can be smoothly separated from the fixing block 2 fixed on the cystoscope body 1, thereby quickly completing the disassembly and replacement of the flexible tube lens 8. At the same time, the sealing ring 3 7 on the connecting seat 9 can effectively prevent liquid from entering the connection part. By rotating the connecting block 2 6 on the connecting seat 9, the sealing ring 2 5 can be made to fit tightly with the sealing ring 4 on the connecting block 3, forming a double sealing structure, further preventing liquid from entering the inside of the endoscope and ensuring the safety of the internal components of the equipment.
