Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a fixing bracket for a laparoscope lens. Background Art

[0002] In the modern medical field, laparoscopic surgery, as a minimally invasive technique, has been widely used due to its characteristics of small trauma and fast recovery. During laparoscopic surgery, the laparoscope lens, as a key device for the surgical field of view, its stability and flexibility directly affect the smooth progress of the surgery and the surgical effect. The traditional fixing method of the laparoscope lens mainly relies on the hand-held operation of medical staff. This method may cause hand fatigue due to long-term holding, and then cause the lens to shake due to hand tremors, affecting the clarity and stability of the lens. In addition, the hand-held operation also limits the freedom of both hands of medical staff during the surgery, making it difficult for medical staff to free their hands for other operations. Content of the Utility Model

[0003] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a fixing bracket for a laparoscope lens.

[0004] The technical solution is as follows: A fixing bracket for a laparoscope lens includes a fixing frame. A universal ball is rotatably connected to the middle of the fixing frame. A lens rod is slidably connected to the universal ball. The lens rod can swing at multiple angles through the universal ball. Two arc-shaped limiting plates are arranged on the fixing frame. The universal ball is located between the two arc-shaped limiting plates. The movement of the universal ball is restricted by the two arc-shaped limiting plates. An unfolding assembly is arranged on the fixing frame. The unfolding assembly is used to release the limitation of the two arc-shaped limiting plates on the universal ball.

[0005] Preferably, the unfolding assembly includes a pressing rod and a connecting rod. Two guiding blocks are fixedly connected to the top of the fixing frame. The two ends of the pressing rod are respectively slidably connected to the two guiding blocks. Oblique sliding grooves are opened at the bottoms of the two ends of the pressing rod. There are two connecting rods, which respectively correspond to the two arc-shaped limiting plates. One end of the connecting rod is fixedly connected to the arc-shaped limiting plate. The other end of the connecting rod is slidably connected in the oblique sliding groove. When the pressing rod moves downward, the connecting rod will drive the arc-shaped limiting plate to move away from the universal ball under the guidance of the oblique sliding groove.

[0006] Preferably, it further includes a slider and a first elastic member. A slider is slidably connected in the oblique sliding groove. The slider is fixedly connected to the connecting rod. A first elastic member is connected between the slider and the fixing frame.

[0007] Preferably, it further includes a limiting ring. A limiting ring for restricting the swinging range of the lens rod is fixedly arranged on the fixing frame and below the universal ball.

[0008] Preferably, the fixing frame includes an upper support rod and two lower support rods. Both ends of the upper support rod are rotatably connected to the lower support rods. At the top of each lower support rod, a clamping post is slidably connected. An elastic member II is connected between the clamping post and the lower support rod. A plurality of card slots matching the clamping posts are formed on the upper support rod.

[0009] Preferably, a clamping plate I is fixedly connected to the bottom of each lower support rod. A clamping plate II is slidably connected to the clamping plate I. At least one screw rod is threadedly connected to the clamping plate II. One end of the screw rod is rotatably connected to the clamping plate I.

[0010] Beneficial effects: Through the flexible connection between the universal ball and the mirror rod, the present utility model provides stable and flexible support for the mirror rod, and through the cooperation of the arc-shaped limiting plate and the unfolding assembly, quickly limits or releases the turning of the universal ball. Thus, during the operation, the lens can be quickly adjusted through the mirror rod, freeing the hands of medical staff and enabling them to focus more on the operation itself, thereby improving the safety and success rate of the operation.

Detailed Embodiments

[0017] The present utility model will be further described below in conjunction with the drawings and detailed embodiments.

[0018] Embodiment 1: Please refer to Figures 1-5, A laparoscopic lens fixing bracket, comprising a fixing frame 1. An annular through groove is formed in the middle of the fixing frame 1. A universal ball 2 is rotatably connected in the annular through groove. A lens rod 15 is slidably connected to the universal ball 2. The lens rod 15 can swing at multiple angles through the universal ball 2. Two arc-shaped limiting plates 3 are arranged on the fixing frame 1. The universal ball 2 is located between the two arc-shaped limiting plates 3. The movement of the universal ball 2 is restricted by the two arc-shaped limiting plates 3. An unfolding assembly 4 is arranged on the fixing frame 1. The unfolding assembly 4 is used to release the limitation of the two arc-shaped limiting plates 3 on the universal ball 2.

[0019] The unfolding assembly 4 includes a pressing rod 401 and a connecting rod 403. Two guiding blocks 14 are fixedly connected to the top of the fixing frame 1. The two ends of the pressing rod 401 are respectively slidably connected to the two guiding blocks 14. Oblique sliding grooves 402 are formed at the bottoms of the two ends of the pressing rod 401. The side of the oblique sliding groove 402 close to the universal ball 2 is the low side, and the side far from the universal ball 2 is the high side. There are two connecting rods 403, which respectively correspond to the two arc-shaped limiting plates 3 one by one. One end of the connecting rod 403 is fixedly connected to the arc-shaped limiting plate 3, and the other end of the connecting rod 403 is slidably connected in the oblique sliding groove 402. When the pressing rod 401 moves downward, the connecting rod 403 will drive the arc-shaped limiting plate 3 to move away from the universal ball 2 under the guidance of the oblique sliding groove 402.

[0020] It further includes a slider 5 and a first elastic member 6. A slider 5 is slidably connected in the oblique sliding groove 402. The slider 5 is fixedly connected to the connecting rod 403. The first elastic members 6 are respectively connected between the fixing frame 1 and the sides of the two sliders 5 away from each other.

[0021] The working principle of this embodiment: First, the fixing frame 1 serves as a support structure. The universal ball 2 is slidably connected to the lens rod 15, providing the lens with the ability to swing at multiple angles. The two limiting plates are closely attached to both sides of the universal ball 2, restricting the natural swing of the universal ball 2 and the lens rod 15, ensuring that the lens remains in a stable and precise position without active adjustment, providing a clear and stable visual angle for the operation.

[0022] When the lens angle needs to be adjusted, the operator pushes the pressing rod 401 downward. The two ends of the pressing rod 401 are slidably connected to the guiding blocks 14 at the top of the fixing frame 1 to ensure smooth movement. As the pressing rod 401 moves downward, the oblique sliding groove 402 at its bottom guides the movement of the connecting rod 403, and then drives the arc-shaped limiting plate 3 to move away from the universal ball 2, thereby releasing the limitation on the universal ball 2. Then, the operator can freely adjust the lens angle by swinging the lens rod 15 forward, backward, left, and right to meet the needs of the operation.

[0023] After the adjustment of the lens viewing angle is completed, the operator releases the pressing rod 401. At this time, the slider 5 moves backward and resets under the elastic action of the first elastic member 6, and drives the arc-shaped limiting plate 3 to move closer to and fit the universal ball 2 again through the transmission of the connecting rod 403, so as to restore the limiting effect on the universal ball 2. In this way, it can ensure that the lens rod 15 is firmly fixed in the adjusted position again, providing stable support for the subsequent surgical operation.

[0024] Embodiment 2: On the basis of Embodiment 1, please refer to Figures 1-5 , a laparoscopic lens fixing bracket, further comprising a limiting ring 7. A limiting ring 7 for restricting the swinging range of the lens rod 15 is fixedly provided on the fixing frame 1 and below the universal ball 2. The limiting ring 7 has an inner diameter slightly larger than the maximum diameter of the lens rod 15 and an outer diameter smaller than the position that the lens rod 15 may reach at the extreme swinging angle, with an annular horn structure.

[0025] The fixing frame 1 includes an upper support rod 101 and two lower support rods 102. Both ends of the upper support rod 101 are rotatably connected to the lower support rods 102. A clamping column 8 is slidably connected to the top of each lower support rod 102. An elastic member II 9 is connected between the bottom of the clamping column 8 and the lower support rod 102. A plurality of card slots 10 matching the clamping column 8 are opened in the lower part of the upper support rod 101.

[0026] A clamping plate I 11 is fixedly connected to the bottom of each lower support rod 102. A clamping plate II 12 is slidably connected to the bottom of the clamping plate I 11. Two screw rods 13 are threadedly connected to the clamping plate II 12. The upper ends of the screw rods 13 are rotatably connected to the clamping plate I 11. By rotating the lower ends of the screw rods 13, the clamping plate II 12 can be axially moved along the screw rods 13, so as to adjust the distance between the clamping plate I 11 and the clamping plate II 12.

[0027] The working principle of this embodiment: The limiting ring 7 forms a blocking surface through its own shape and position. When the lens rod 15 swings to approach its maximum range, the lens rod 15 will contact the limiting ring 7, so that it cannot continue to swing in this direction. In this way, the swinging range of the lens rod 15 is restricted, ensuring that the lens is adjusted within a reasonable angle, thus guaranteeing the smooth progress of the operation and the stability of the operation; the angle adjustment between the upper support rod 101 and the two lower support rods 102 is realized through rotational connection. The clamping column 8 at the top of the lower support rod 102 cooperates with the card slot 10 on the upper support rod 101 and is automatically locked under the action of the elastic member II 9 to ensure the stability of the bracket at different surgical positions and angles; at the same time, a clamping plate I 11 and a clamping plate II 12 are also provided at the bottom of the lower support rod 102. By simultaneously rotating the two screw rods 13 to make the clamping plate II 12 approach and clamp the clamping plate I 11, it is fixed on a support surface such as the edge of the operating table, realizing the stable installation and flexible adjustment of the bracket.

[0028] The above embodiments are provided for those skilled in the art to implement or use the present utility model. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present utility model. Therefore, the protection scope of the present utility model is not limited by the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
