Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an endoscope self-locking handle. Background Technology

[0002] In modern minimally invasive surgery, endoscopes are a commonly used medical tool that allows doctors to perform surgical procedures through a small incision, thereby reducing patient trauma and recovery time. Endoscopes are usually equipped with a handle, which doctors use to control the direction and position of the endoscope.

[0003] Existing technologies disclose several utility model patents in the field of medical device manufacturing. Among them, utility model patent application number 202421416933.4 discloses an endoscope self-locking handle and an endoscope, including a housing and a drive assembly. The housing has gear patterns on at least one inner wall. The drive assembly includes a lever and a drive wheel. The drive wheel is rotatably mounted inside the housing, and the lever is connected to the drive wheel. The controllable portion of the lever is located outside the housing. At least one side of the drive wheel and / or the lever has a protruding bump that engages with the gear patterns on the corresponding side of the housing. When the drive assembly moves, it needs to overcome the resistance between the bump and the gear patterns to move the drive wheel. When the drive wheel rotates to its position, the bump and the housing gear patterns form a self-locking mechanism, limiting the position of the drive wheel. The entire handle has a simple structure, is easy to assemble, and has simple operation steps without additional locking actions, conforming to user habits.

[0004] However, the above method still has the following drawbacks in actual use: although it can achieve the self-locking function and conforms to the operating habits, most areas of the handle surface are not equipped with auxiliary structures. When the endoscope position needs to be finely adjusted during the operation, the handle is prone to slippage, which can affect the accuracy and safety of the operation and reduce the flexibility of the handle.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1 and Figure 4As shown, in this embodiment, an endoscope self-locking handle includes a handle body 1, an endoscope tube 2 rotatably connected inside the handle body 1, a self-locking button 3 inside the handle body 1, a snap-fit ​​structure 6 fixedly connected to the left side of the handle body 1, a concave plate 5 overlapping the left side of the handle body 1, the snap-fit ​​structure 6 being connected to the concave plate 5, an auxiliary structure 7 inside the concave plate 5, a groove 8 being formed inside the concave plate 5, the auxiliary structure 7 being slidably connected inside the groove 8, the auxiliary structure 7 including a drive rod 701, a tension band 702, a toothed plate 1 704, a toothed plate 2 705, and a sliding plate 706, a gear 703 fixedly connected to the outer surface of the drive rod 701, a spring 707 on one side of the sliding plate 706, a toothed plate 1 704 slidably connected inside the concave plate 5, and a toothed plate 2 705 slidably connected inside the concave plate 5.

[0023] like Figure 1 and Figure 3 As shown, a data connection cable 4 is fixedly connected to the bottom of the handle body 1, the endoscope tube 2 is connected to the self-locking button 3, the drive rod 701 is rotatably connected in the concave plate 5, the toothed plate 1 704 meshes with the gear 703, the toothed plate 2 705 meshes with the gear 703, the tension band 702 is slidably connected in the concave plate 5, the tension band 702 overlaps with the slide plate 706, the slide plate 706 is slidably connected in the groove 8, the slide plate 706 is connected in the groove 8 by the spring 707, one end of the tension band 702 is connected to the toothed plate 1 704, and the other end of the tension band 702 is connected to the toothed plate 2 705.

[0024] By setting up the slide plate 706 and the spring 707, when the toothed plate 1 704 and the toothed plate 2 705 move relative to each other, the two ends of the tension band 702 will retract accordingly. When the tension band 702 retracts, it will drive the slide plate 706 to slide in the groove 8. When the slide plate 706 slides, it will cause the spring 707 to deform, so that the slide plate 706 and the spring 707 provide a certain support for the movement of the tension band 702, avoiding the phenomenon of the tension band 702 colliding with the concave plate 5 when moving. When the tension band 702 loses resistance, it will be reset by the spring 707.

[0025] like Figure 4 As shown, the snap-fit ​​structure 6 includes a limiting plate 601 and a mounting plate 602. The limiting plate 601 is fixedly connected to the side of the handle body 1, and the mounting plate 602 is fixedly connected to the outer surface of the concave plate 5. The concave plate 5 is snapped into the limiting plate 601, and the mounting plate 602 overlaps with the limiting plate 601. The mounting plate 602 is provided with bolts 603, and the mounting plate 602 is connected to the limiting plate 601 through the bolts 603.

[0026] By setting the snap-fit ​​structure 6, when the concave plate 5 overlaps with the left side of the handle body 1 via the mounting plate 602, and the mounting plate 602 overlaps with the limiting plate 601, the mounting plate 602 is threadedly connected to the limiting plate 601 via bolts 603, so that the concave plate 5 and the handle body 1 can be assembled. When the auxiliary structure 7 is damaged, the concave plate 5 can be replaced, avoiding the need to replace the entire handle and reducing unnecessary processing costs.

[0027] This utility model provides a self-locking handle for an endoscope, the specific working principle of which is as follows:

[0028] When the handle is in use, the concave plate 5 is attached to the left side of the handle body 1 via the mounting plate 602, and the concave plate 5 is snapped into the limiting plate 601. The mounting plate 602 is attached to the limiting plate 601, and the mounting plate 602 is threadedly connected to the limiting plate 601 via bolts 603.

[0029] During subsequent use, adjustments can be made within the handle body 1. Once the adjustment is complete, the self-locking button 3 can be used to lock the mechanism. When a surgical examination is required, the hand can be held in the concave plate 5, and the tension band 702 will contact the back of the hand. The built-in motor drives the drive rod 701 to rotate. Since gear 703 meshes with toothed plate 1 704 and gear 703 meshes with toothed plate 2 705, toothed plate 1 704 and toothed plate 2 705 will move relative to each other, and the two ends of the tension band 702 will contract accordingly. When the tension band 702 contracts, it will cause the slide plate 706 to slide within the groove 8. When the slide plate 706 slides, it will cause the spring 707 to deform, and the tension band 702 will clamp the back of the hand.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
