Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically a knob for controlling the direction of a medical endoscope insertion tube. Background Technology

[0002] In the medical field, especially in highly precise minimally invasive surgery, the accurate control of the insertion direction of the medical endoscope is undoubtedly the key to the entire surgical process. It not only directly relates to the success or failure of the surgery, but also profoundly affects the patient's treatment outcome and recovery process.

[0003] Traditional endoscopic insertion tube angle adjustment relies on single-stage gear or lever transmission systems. While this method achieves angle adjustment to some extent, the non-linear relationship between the rotation angle and the rotation amplitude of the insertion tube makes it difficult for doctors to accurately predict and adjust the direction of the insertion tube during operation. This can easily lead to overshoot and lag, thus affecting the accuracy and safety of the surgical procedure.

[0004] Therefore, this application provides a knob for controlling the direction of the insertion tube of a medical endoscope to solve the above problems. Utility Model Content

[0005] This application provides a knob for controlling the direction of a medical endoscope insertion tube, aiming to solve the problems mentioned in the background art, such as the nonlinear transmission system that the angle adjustment of the traditional endoscope insertion tube relies on, which makes it difficult for doctors to accurately predict and adjust the direction during operation, and easily causes overshoot and lag, affecting the accuracy and safety of the operation.

[0006] To achieve the above objectives, this application provides the following technical solution: a knob for controlling the direction of a medical endoscope insertion tube, comprising a rotating ring rotatably connected to the outside of the endoscope handle and a threaded transmission assembly disposed within the rotating ring for engaging with the outside of the insertion tube;

[0007] The threaded drive assembly includes a hollow column fixedly disposed at the top inner side of the rotating ring and coaxially disposed with the rotating ring, a threaded groove formed on the inner side of the hollow column, and a threaded tube passing through the hollow column and the rotating ring and fixedly connected to the outside of the insertion tube. The threaded tube is screwed to the threaded groove. Through the combined design of the rotating ring, the hollow column, the threaded groove, and the threaded tube, the doctor can easily adjust the direction of the insertion tube at multiple angles by rotating the rotating ring and utilizing the helical linear movement characteristics of the threaded tube, making the operation more labor-saving and precise. At the same time, the screwed design of the threaded groove and the threaded tube ensures stability during rotation. Due to the characteristics of the threaded structure, the rotating ring can provide a stable and predictable advancing or retracting force when rotating, which makes the rotation of the insertion tube smooth and controllable, improving the accuracy and safety of the surgical operation.

[0008] Preferably, to enhance grip stability, the outer side of the rotating ring is fixedly provided with vertical anti-slip textures; the design of the vertical anti-slip textures can increase the friction between the fingers and the rotating ring, preventing slippage caused by hand sweat or improper operation during operation. This not only improves grip stability, but also allows doctors to hold the ring more comfortably during long-term operation, reducing hand fatigue and helping to improve the continuity and precision of the surgery.

[0009] Preferably, to further ensure the linear spiral movement of the threaded tube, a tail sleeve is screwed to the outer side of the rotating ring away from the endoscope handle. The threaded tube passes through the tail sleeve and is slidably connected inside the tail sleeve. The design of the tail sleeve provides an additional support and guiding structure for the threaded tube. When the rotating ring rotates, the tail sleeve can rotate with the rotating ring to ensure that the threaded tube slides stably on a predetermined trajectory, further enhancing the stability of the entire structure.

[0010] Preferably, to facilitate the connection between the knob and the endoscope handle, the knob further includes a fastening mechanism disposed within the rotating ring and connected to the hollow post; the fastening mechanism design makes the connection between the rotating ring and the endoscope handle simple and quick.

[0011] Preferably, to facilitate accurate connection, the fastening mechanism includes a slot formed inside the rotating ring corresponding to the outer side of the hollow column, and the outer side of the endoscope handle is rotatably connected to the slot; the slot design provides initial positioning for the connection between the knob and the endoscope handle, making the connection between the rotating ring and the endoscope handle more convenient and accurate.

[0012] Preferably, for further connection, the fastening mechanism further includes a limiting rib fixedly disposed within the slot corresponding to the outer side of the hollow post and arranged in a ring for insertion into the endoscope handle, and a protrusion fixedly installed on the end of the limiting rib away from the hollow post. The endoscope handle has a guide ring groove inside that matches the protrusion, and the protrusion is slidably connected within the guide ring groove. The combination of the limiting rib and the protrusion provides additional support and fixation for the connection between the rotating ring and the endoscope handle. The protrusion's fit with the guide ring groove inside the endoscope handle allows the rotating ring to rotate smoothly while maintaining a stable connection, ensuring the linear helical movement of the threaded tube.

[0013] The knob that controls the direction of the medical endoscope insertion tube, through the cooperation of a rotating ring and a threaded transmission assembly, allows doctors to adjust the direction of the insertion tube at multiple angles by rotating the rotating ring and utilizing the helical linear movement characteristics of the threaded tube, making the operation more effortless and precise.

[0014] The knob that controls the direction of the medical endoscope insertion tube ensures stability during rotation through the screw connection design between the threaded groove and the threaded tube. Due to the characteristics of the thread structure, the rotating ring can provide a stable and predictable advance or retraction force when rotating, which makes the rotation of the insertion tube smooth and controllable, improving the accuracy and safety of the surgical operation.

[0015] The knob that controls the direction of the medical endoscope insertion tube features a vertical anti-slip texture design, which increases the friction between the finger and the rotating ring, preventing slippage due to hand sweat or improper operation during the procedure. This not only improves grip stability but also allows doctors to hold the instrument more comfortably during prolonged operations, reducing hand fatigue and contributing to improved surgical continuity and precision.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] This embodiment provides a knob for controlling the direction of the insertion tube of a medical endoscope, such as... Figures 1-3As shown, the knob includes a rotating ring 1 rotatably connected to the outside of the endoscope handle and a threaded transmission assembly 2 disposed inside the rotating ring 1 for connecting to the outside of the insertion tube; the threaded transmission assembly 2 includes a hollow post 21 fixedly disposed at the top of the inner side of the rotating ring 1 and coaxially disposed with the rotating ring 1, a threaded groove 22 opened on the inner side of the hollow post 21, and a threaded tube 23 passing through the hollow post 21 and the rotating ring 1 and fixedly connected to the outside of the insertion tube, the threaded tube 23 being screwed to the threaded groove 22.

[0025] In order to enhance grip stability, vertical anti-slip texture 11 is fixedly provided on the outer side of the rotating ring 1. The design of the vertical anti-slip texture 11 can increase the friction between the fingers and the rotating ring 1, preventing slippage caused by hand sweat or improper operation during operation. This not only improves grip stability, but also allows doctors to hold the ring more comfortably during long-term operation, reducing hand fatigue and helping to improve the continuity and precision of the surgery.

[0026] In addition, to further ensure the linear spiral movement of the threaded tube 23, a tail sleeve 12 is screwed onto the outer side of the rotating ring 1 away from the endoscope handle. The threaded tube 23 passes through the tail sleeve 12 and is slidably connected inside the tail sleeve 12. The design of the tail sleeve 12 provides an additional support and guide structure for the threaded tube 23. When the rotating ring 1 rotates, the tail sleeve 12 can rotate with the rotating ring 1 to ensure that the threaded tube 23 slides stably on the predetermined trajectory, further enhancing the stability of the entire structure.

[0027] In use, the doctor holds the rotating ring 1 with their fingers and rotates it. At this time, the rotating ring 1 will synchronously drive the hollow column 21 inside to rotate. Since the hollow column 21 is provided with a threaded groove 22, the threaded groove 22 can also rotate synchronously with the rotation of the hollow column 21. Due to the guidance of the coccyx sleeve 12, the threaded tube 23 screwed to the threaded groove 22 will move linearly in a spiral within the hollow column 21 as the threaded groove 22 rotates. The threaded tube 23 is fixedly connected to the outside of the endoscope insertion tube. Therefore, rotating the rotating ring 1 by different numbers of turns or angles will cause the threaded tube 23 to rotate linearly in a spiral, directly driving the insertion tube to rotate by different angles to meet different exploratory needs.

[0028] Specifically, the knob also includes a fastening mechanism 3 disposed in the rotating ring 1 and connected to the hollow post 21. The fastening mechanism 3 includes a slot 31 opened in the rotating ring 1 corresponding to the outside of the hollow post 21. The outside of the endoscope handle is rotatably connected in the slot 31. The fastening mechanism 3 also includes a limiting rib 32 fixedly disposed in the slot 31 corresponding to the outside of the hollow post 21 and arranged in a ring for insertion into the inside of the endoscope handle, and a protrusion 33 fixedly installed on the end of the limiting rib 32 away from the hollow post 21. The inside of the endoscope handle is provided with a guide ring groove that matches the protrusion 33. The protrusion 33 is slidably connected in the guide ring groove.

[0029] When installing the knob, first align the slot 31 of the rotating ring 1 with the rotating connection part of the endoscope handle, and insert the endoscope handle into the slot 31. As the endoscope handle is inserted, the limiting rib 32 retracts and enters the endoscope handle. After the limiting rib 32 is fully inside the endoscope handle, the limiting rib 32 recovers under the action of elasticity and inserts the protrusion 33 into the guide ring groove inside the endoscope handle. When the doctor needs to adjust the insertion tube angle of the endoscope, the rotating ring 1 can be rotated. At this time, under the limiting sliding action of the protrusion 33 and the guide ring groove, the rotating ring 1 will drive the hollow column 21 to rotate synchronously and stably. Thus, as the hollow column 21 rotates, the threaded tube 23 can make linear rotational movement, thereby realizing the adjustment of multiple angles of the insertion tube.

[0030] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
