Description

Technical Field

[0001] This utility model belongs to the field of endoscope technology, and in particular relates to an endoscope actuation component and handle. Background Technology

[0002] An endoscope is a precision instrument that can be inserted into narrow spaces for observation, inspection, and operation. It is widely used in medical diagnosis, industrial inspection, scientific research, and other fields. In the medical field, it helps doctors to directly observe lesions in internal organs. In the industrial field, it can be used to inspect the internal structure of pipes and machinery. In scientific research, it helps in the observation and research of the microscopic world.

[0003] Traditional toggle levers are mostly exposed and lack effective protective structures. During equipment transportation, storage, or use, they are easily corroded by dust and liquids, as well as by external impacts, leading to wear and jamming of internal transmission components. This, in turn, affects the adjustment accuracy and service life of the endoscope. On the other hand, due to the lack of a reliable locking mechanism, unintentional touches or limb movements by medical staff during operation may cause the toggle lever to move unexpectedly, resulting in a deviation in the endoscopic observation angle. This not only interferes with the normal examination process but may also cause diagnostic omissions or surgical errors due to angular errors, seriously affecting the safety and accuracy of medical work.

[0004] To address these issues, we provide an endoscope actuation assembly and handle. Utility Model Content

[0005] The purpose of this utility model is to provide an endoscope toggle assembly and handle. Through the cooperation of the toggle mechanism and the reset mechanism, it solves the problem that in the prior art, the endoscope toggle lever is mostly exposed and lacks an effective protective structure. This can lead to the endoscope's observation angle shifting due to unintentional touch or limb movement during operation.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to an endoscope actuation assembly and handle, comprising a housing, a display screen fixedly connected to the surface of the housing, an actuation mechanism provided at the bottom of the housing surface, the actuation mechanism including an actuating rod, one side of the actuating rod being movably connected to the housing, a positioning seat fixedly connected to the bottom of the housing surface and located on the surface of the actuating rod, a limiting sleeve fixedly connected to one side of the positioning seat, and a reset mechanism fixedly connected to both sides of the surface of the positioning seat, a protective sleeve covered on the surface of the limiting sleeve, connecting blocks fixedly connected to both sides of the inner wall of the protective sleeve, a self-locking groove formed on the surface of the connecting blocks, and limiting rods movably connected to both sides of the inner wall of the limiting sleeve via rotating shafts, one side of the limiting rod extending into the inner cavity of the self-locking groove, the limiting sleeve adopting a cylindrical design. Its inner wall is fitted outside the actuating rod, providing a certain amount of room for movement. This ensures that the actuating rod can rotate freely while limiting its radial sway, improving operational stability. The connecting block and the limiting groove on the surface of the limiting sleeve form a sliding pair. The connecting block can slide axially within the limiting groove, ensuring that the protective sleeve does not shift during lifting and lowering. The length of the limiting groove determines the stroke of the protective sleeve, allowing it to completely cover or expose the actuating rod. The self-locking groove adopts a dovetail groove structure, and the end of the limiting rod is a matching cylindrical structure. When the protective sleeve descends, the limiting rod moves along the self-locking groove under the action of the rotating shaft. After passing the protruding part of the self-locking groove, it is locked into the groove under the action of spring force, achieving automatic locking. When pressed again, the limiting rod deforms under force and disengages from the groove, and the protective sleeve rises under the action of the reset mechanism.

[0008] The present invention is further configured such that the reset mechanism includes a sleeve, one side of which is fixedly connected to a positioning seat, a spring is fixedly connected to the inner cavity of the sleeve, a reset rod is fixedly connected to one side of the spring, and one side of the reset rod is fixedly connected to a protective sleeve. The combination of the spring and the reset rod allows the protective sleeve to quickly return to its initial position after unlocking, eliminating the need for manual operation and simplifying the usage process. The elasticity of the spring can absorb the impact force during pressing, reducing mechanical damage to the limiting sleeve and the toggle lever, and extending the service life. The sleeve provides guidance and support for the spring, preventing the spring from bending laterally during compression and ensuring the reliability of the reset action.

[0009] The present invention is further configured such that limit grooves are provided on both sides of the surface of the limiting sleeve, and one side of the connecting block extends into the inner cavity of the limit groove. The connecting block slides in the limit groove, which restricts the movement trajectory of the protective sleeve, prevents it from deviating or detaching during the lifting process, and enhances the structural stability. The length and shape of the limit groove can precisely control the stroke of the protective sleeve, ensuring that it completely covers or exposes the lever, and achieves a reliable protective function.

[0010] The present invention is further configured such that a positioning post is fixedly connected to one side of the reset rod, and one side of the positioning post extends into the inner cavity of the spring. The positioning post is inserted into the inner cavity of the spring to prevent the spring from twisting or deforming during repeated compression and extension, and to ensure consistent reset force.

[0011] The present invention is further configured such that side plates are fixedly connected to both sides of the housing. The side plates are L-shaped. The L-shaped side plates increase the force-bearing area, disperse the impact force from the outside, improve the deformation resistance of the housing, and protect the internal precision components.

[0012] The present invention is further configured such that a connecting seat is fixedly connected to the top of the housing, a wire is connected to one side of the connecting seat, and a lens is connected to one side of the wire. The connecting seat provides a stable interface for the wire, reducing poor contact caused by shaking or pulling, and ensuring the stability of image and data transmission.

[0013] An endoscope actuation component handle includes a handle body, the top of which is fixedly connected to a housing, and anti-slip strips are fixedly connected to both sides of the handle body. The anti-slip strips are made of silicone material, which significantly increases the friction between the hand and the handle body, especially when the hand is wet or when wearing gloves. The position and shape of the anti-slip strips are designed according to the mechanical distribution of the hand to reduce local pressure concentration and reduce fatigue during long-term operation.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model provides an efficient protective function for the lever through an innovative press-lock design. When the protective cover is pressed down, it is securely locked in the low position, and the lever is in the unlocked state, which facilitates quick and accurate adjustment by medical staff. When the protective cover is pressed again to rise, the limit rod and the self-locking slot cooperate tightly to form a reliable lock, effectively preventing accidental activation caused by external factors and ensuring the stability of the endoscope observation angle.

[0016] 2. This utility model can block dust and liquid from entering from all directions by raising the protective cover, buffering external impact, protecting the lever and its internal transmission structure, and significantly extending the service life of the equipment. This design, which combines protection and convenience, not only reduces operational errors caused by accidental touch and improves the safety and accuracy of medical operations, but also simplifies the protective operation process, achieving a perfect unity of protection and efficient operation, and bringing great convenience and reliability to the use of endoscopes.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figure 1-6 This utility model relates to an endoscope actuation assembly and handle, comprising a housing 1, a display screen 2 fixedly connected to the surface of the housing 1, an actuation mechanism 3 provided at the bottom of the surface of the housing 1, the actuation mechanism 3 including an actuation rod 31, one side of the actuation rod 31 being movably connected to the housing 1, a positioning seat 32 fixedly connected to the bottom of the surface of the housing 1 and located on the surface of the actuation rod 31, a limiting sleeve 33 fixedly connected to one side of the positioning seat 32, a reset mechanism 34 fixedly connected to both sides of the surface of the positioning seat 32, a protective sleeve 35 covering the surface of the limiting sleeve 33, connecting blocks 36 fixedly connected to both sides of the inner wall of the protective sleeve 35, a self-locking groove 37 opened on the surface of the connecting block 36, and limiting rods 38 movably connected to both sides of the inner wall of the limiting sleeve 33 via a rotating shaft, one side of the limiting rod 38 extending into the inner cavity of the self-locking groove 37.

[0028] Specifically: The limiting sleeve 33 adopts a cylindrical design, and its inner wall is fitted outside the actuating rod 31, providing a certain amount of room for movement. This ensures that the actuating rod 31 can rotate freely while limiting its radial sway, thus improving operational stability. The connecting block 36 and the limiting groove 4 on the surface of the limiting sleeve 33 form a sliding pair. The connecting block 36 can slide axially within the limiting groove 4, ensuring that the protective sleeve 35 does not shift during lifting and lowering. The length of the limiting groove 4 determines the stroke of the protective sleeve 35, allowing it to completely cover or expose the actuating rod 31. The self-locking groove 37 adopts a dovetail groove structure, and the end of the limiting rod 38 is a matching cylindrical structure. When the protective sleeve 35 descends, the limiting rod 38 moves along the self-locking groove 37 under the action of the rotating shaft. After passing the protruding part of the self-locking groove 37, it is locked into the groove under the force of the spring 342, achieving automatic locking. When pressed again, the limiting rod 38 deforms under force and disengages from the groove, and the protective sleeve 35 rises under the action of the reset mechanism 34.

[0029] Example 2

[0030] Please see Figure 1-6 Based on Embodiment 1, the reset mechanism 34 includes a sleeve 341, one side of which is fixedly connected to the positioning seat 32. A spring 342 is fixedly connected to the inner cavity of the sleeve 341. A reset rod 343 is fixedly connected to one side of the spring 342. One side of the reset rod 343 is fixedly connected to the protective sleeve 35. Limiting grooves 4 are provided on both sides of the surface of the limiting sleeve 33. One side of the connecting block 36 extends into the inner cavity of the limiting groove 4. A positioning post 5 is fixedly connected to one side of the reset rod 343. One side of the positioning post 5 extends into the inner cavity of the spring 342. Side plates 6 are fixedly connected to both sides of the housing 1. The side plates 6 are L-shaped. A connecting seat 7 is fixedly connected to the top of the housing 1. A wire 8 is connected to one side of the connecting seat 7. A lens 9 is connected to one side of the wire 8.

[0031] Specifically: The combination of spring 342 and reset lever 343 allows the protective sleeve 35 to quickly return to its initial position after unlocking, eliminating the need for manual operation and simplifying the usage process. The elasticity of spring 342 absorbs the impact force during pressing, reducing mechanical damage to the limiting sleeve 33 and the actuating lever 31, and extending their service life. Sleeve 341 provides guidance and support for spring 342, preventing lateral bending of spring 342 during compression and ensuring the reliability of the reset action. Connecting block 36 slides within the limiting groove 4, restricting the movement trajectory of the protective sleeve 35 and preventing it from shifting or detaching during lifting and lowering, thus enhancing its performance. To ensure structural stability, the length and shape of the limiting groove 4 precisely control the stroke of the protective sleeve 35, ensuring that it completely covers or exposes the toggle lever 31, thus achieving reliable protection. The positioning post 5 is inserted into the inner cavity of the spring 342 to prevent the spring 342 from twisting or deforming during repeated compression and extension, ensuring consistent reset force. The L-shaped side plate 6 increases the force-bearing area, disperses the impact force from the outside, improves the deformation resistance of the housing 1, and protects the internal precision components. The connecting seat 7 provides a stable interface for the wire 8, reducing poor contact caused by shaking or pulling, and ensuring the stability of image and data transmission.

[0032] Example 3

[0033] Please see Figure 1-6 This utility model is a handle for an endoscope actuation assembly, including a handle body 10, the top of the handle body 10 being fixedly connected to the housing 1, and anti-slip strips 11 being fixedly connected to both sides of the handle body 10.

[0034] Specifically: The anti-slip strip 11 is made of silicone material, which significantly increases the friction between the hand and the handle body 10, especially when the hand is wet or when wearing gloves. The position and shape of the anti-slip strip 11 are designed according to the mechanical distribution of the hand, which reduces local pressure concentration and reduces fatigue during long-term operation.

[0035] The working principle of this utility model is as follows: When the protective sleeve 35 is pressed down, the connecting block 36 slides down along the limiting groove 4 on the surface of the limiting sleeve 33. During this process, the limiting rods 38 connected to both sides of the inner wall of the limiting sleeve 33 through the rotating shaft rotate outward under the pushing force of the protective sleeve 35 pressing down, passing over the protruding part of the self-locking groove 37. When the protective sleeve 35 descends to the predetermined position, the limiting rods 38 are engaged in the inner cavity of the self-locking groove 37, realizing the automatic locking of the protective sleeve 35. At this time, the toggle lever 31 is in an operable state, and the operator can adjust it.

[0036] When the adjustment is complete or the lever 31 is no longer needed, press the protective sleeve 35 again. The applied external force causes the limiting rod 38 to deform and disengage from the self-locking groove 37. At the same time, the spring 342 is in a compressed state during the pressing of the protective sleeve 35, storing elastic potential energy. When the limiting rod 38 disengages from the groove, the spring 342 releases its elastic potential energy, pushes the reset rod 343, and then drives the protective sleeve 35 to slide upward along the limiting groove 4. After rising, the protective sleeve 35 completely covers the lever 31, protecting it from dust, liquid intrusion, and accidental contact.

[0037] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
