Description

Technical Field

[0001] The utility model relates to the field of auxiliary camera devices, in particular to a cilia mechanical stimulation needle auxiliary camera device. Background Technique

[0002] The measurement of tactile and mechanical pain thresholds is an important means to evaluate the function of pain receptors (such as nociceptive nerve endings). By comparing the tactile and mechanical pain thresholds under different experimental conditions (such as drug treatment, gene knockout, nerve injury, etc.), scientists can understand which factors affect pain perception, so as to deeply understand the physiological and pathological mechanisms of pain. Since there are many similarities between humans and animals in terms of physiology and pathology, measuring the tactile and mechanical pain thresholds of animals can also provide important references for human pain research and treatment. By comparing the differences in tactile and mechanical pain thresholds between different species, researchers can understand how these differences affect pain perception, so as to develop more effective and safe pain treatment methods.

[0003] When treating pain-related diseases, whether a drug is effective usually needs to be judged by evaluating whether it can reduce the mechanical pain threshold of animals. When developing new analgesic drugs in pain mechanism research, researchers will use tools such as cilia stimulation needles to measure the mechanical pain thresholds of animals before and after drug treatment, so as to evaluate the analgesic effect of the drugs.

[0004] In current experimental studies, although devices such as electronic tactile pain measuring instruments and cilia mechanical stimulation needles provide effective tools for evaluating tactile and pain responses, due to the limitations of angles and distances, they often cannot observe the responses of experimental animals in real time and clearly, and it is difficult to accurately locate the test area. This situation may not only lead to errors and inconsistencies in experimental results, but also requires experimental personnel to continuously manually adjust the device angle in actual operation, thus increasing the difficulty and complexity of the experiment. Summary of the Invention

[0005] The purpose of the utility model is to overcome the problem that when using a cilia mechanical stimulation needle or an electronic tactile pain measuring instrument, the responses of experimental animals cannot be clearly observed.

[0006] To achieve the above purpose, the design idea for solving the technical problem of the utility model is to design a telescopic bracket. One end of the bracket is a circular structure used to be sleeved and fixed on the handheld rod of the cilia mechanical stimulation needle or the electronic tactile pain measuring instrument. The other end of the bracket is a telescopic bracket. A manual rotation mechanism is arranged at the front end of the bracket. The rotation mechanism is fixedly connected with a telescopic structure that can drive the camera to telescopically rotate. The camera transmits the captured image to the display screen for the purpose of observation.

[0007] To achieve the above object, the technical solution adopted by the present utility model to solve its technical problems is as follows:

[0008] A cilia mechanical stimulation needle-assisted camera device, comprising a support member, a telescopic rod, a rotating mechanism and a camera support frame. The support member is used to sleeve on the hand-held rod of the cilia mechanical stimulation needle; the telescopic rod is arranged through the top of the support member; a rotating mechanism is arranged at the top of the telescopic rod, and the rotating mechanism is fixedly connected with the camera support frame.

[0009] A further optimized solution of the above solution is: the support member is a hollow frustum.

[0010] By adopting the above technical solution, further, the support member is a circular ring.

[0011] By adopting the above technical solution, further, the rotating mechanism is a ratchet mechanism.

[0012] By adopting the above technical solution, further, the camera support frame includes: a telescopic frame and a fixed frame. The telescopic frame is detachably fixed on the rotating mechanism, and the fixed frame is fixed on the telescopic frame.

[0013] By adopting the above technical solution, further, a groove is provided at the bottom of the camera support frame and is detachably fixed on the rotating mechanism.

[0014] The beneficial effects of the present utility model are:

[0015] 1. The support member of the present utility model adopts a hollow frustum or circular ring design, enabling the device to be flexibly sleeved on the hand-held rod of the cilia mechanical stimulation needle, adapting to cilia mechanical stimulation needles or electronic tactile pain measuring instruments with different diameters, and enhancing the versatility and adaptability of the device.

[0016] 2. The telescopic rod and the telescopic camera support frame provided by the present utility model allow the device to be flexibly adjusted in height and length, thereby adapting to different working scenarios and camera requirements.

[0017] 3. The rotating mechanism of the present utility model enables the camera support frame to rotate and position more precisely. Compared with traditional electronically lifted cameras, the cost is lower. In different experimental environments, there is no need for electrical connection and remote control, and manual adjustment is more time-saving and accurate. Description of the Drawings

[0031] Embodiment 1

[0032] Refer to Figures 1-10, a cilia mechanical stimulation needle-assisted camera device, comprising a support member 10, a telescopic rod 20, a rotating mechanism 30 and a camera support frame 40, characterized in that the support member 10 is used to be sleeved on the cilia mechanical stimulation needle; two telescopic rods 20 are oppositely and penetratingly arranged at the top of the support member 10; a rotating mechanism 30 is arranged at the top end of the telescopic rod 20, and the rotating mechanism 30 is fixedly connected with the camera support frame 40.

[0033] During specific implementation, the support member 10 has an annular structure with a certain thickness and height, and the inner diameter range of its ring is set to 1-3 cm. A rubber ring is ingeniously arranged inside the ring to increase the friction with the hand-held rod of the cilia mechanical stimulation needle, ensuring that the device can be stably sleeved on the cilia mechanical stimulation needle, and at the same time improving the stability of the entire device during use, providing a reliable guarantee for accurate imaging.

[0034] During specific implementation, the snap ring 21 inside the telescopic rod 20 adopts a "U"-shaped design and the material is spring steel. One end of the snap ring 21 is fixedly connected with the telescopic rod 20, and the other end has a conical protrusion, and a hole is provided at the lower end of the telescopic rod 20. During the telescopic process, the snap ring 21 remains in a retracted state; when stretched to a specific position, the conical protrusion penetrates the hole to achieve positioning. This design allows the protrusion to slide out of the hole by applying pressure to achieve continuous adjustment of the telescopic rod. The telescopic rod 20 is a hollow structure, and the diameter range of the telescopic rod 20 is 5-8 mm. The telescopic rod 20 is connected to the support member 10 in a penetrating manner to ensure stable and flexible adjustment during the experiment.

[0035] During specific implementation, a rotating mechanism 30 is arranged at the top end of the telescopic rod 20. The rotating mechanism 30 includes a rotating shaft 31, a handle 312, an internal gear 32 and a pawl 311. The telescopic rod 20 is divided into a first telescopic rod 22 and a second telescopic rod 23. The top end of the first telescopic rod 22 is rotatably connected with the rotating shaft 31 and fixedly connected with the internal gear 32. The rotating shaft 31 penetrates the internal gear 32 and is rotatably connected with the second telescopic rod 23. The handle 312 is fixedly connected to the other end of the rotating shaft 31. The pawl 311 is fixed on the rotating shaft 31 through a torsion spring and is engaged with the teeth of the internal gear 32. This design enables the pawl 311 to remain stable when no adjustment is required, and when adjustment is needed, by gently rotating the rotating shaft 31, the pawl 311 can quickly respond and lock at the corresponding position of the internal gear 32, preventing the angle of the camera from changing due to the action of gravity or accidental touch, thereby achieving precise control of the angle of the camera support frame 40. This design not only enhances the stability of the device but also greatly improves the flexibility and convenience of operation.

[0036] During specific implementation, the extension range of the telescopic rod 20 is 5-20 cm.

[0037] In specific implementation, the camera support frame 40 includes a telescopic frame 41 and a fixed frame 42. The top and bottom of the telescopic frame 41 are respectively provided with "L"-shaped clamping devices, which makes the operation more convenient compared with the spring clip type telescopic structure when the telescopic frame 41 is telescoped, and is more suitable for fine height adjustment. Thus, it ensures that the camera can flexibly adjust the shooting position in different scenarios. At the same time, the telescopic frame 41 is detachably clamped with the rotating shaft 31, so that the camera can be driven by the rotating shaft 31 to rotate 360°, meeting the shooting requirements at different angles. The fixed frame 42 is telescopically clamped with the telescopic frame 41, and its telescopic principle is the above principle, providing stable support for the camera to ensure that it will not shake or shift during the shooting process. The camera can be firmly fixed on the fixed frame 42 to achieve clear and stable shooting effects. And the telescopic range of the telescopic frame 41 is 2 to 5 cm, adjusting different heights for different lengths of fiber filaments to more clearly observe the activity responses of experimental animals.

[0038] In specific implementation, telescopic grippers 421 are respectively and penetratingly arranged on both sides of the fixed frame 42, and the two are fixedly connected by a compression spring fixed inside the fixed frame 42. When the camera needs to be removed, only the grippers 421 need to be pulled. This improves the versatility and compatibility of the fixed frame, enabling it to firmly clamp cameras of different size specifications, greatly expanding its applicable range, and reducing the trouble and cost of replacing the fixed frame due to camera size differences.

[0039] In specific implementation, the device can be entirely made of materials with higher strength and stronger corrosion resistance, such as carbon fiber or high-strength plastics, making the entire device lighter and more robust to meet the usage requirements in different environments.

[0040] In specific implementation, the camera adopts an IMAX258 image sensor, which is a high-performance, high-sensitivity and low-noise CMOS image sensor, and the camera is wired-connected to reduce the weight of the device and increase flexibility.

[0041] During specific operation, the camera is clamped on the fixed frame 42, the telescopic rod 20 is adjusted to the required length, and the conical protrusion of the spring clip 21 penetrates through the hole to achieve limit fixation. The device is sleeved on the ciliary mechanical stimulation needle, and then the telescopic rod 20 is adjusted to an appropriate length. After ensuring the stability of the telescopic rod 20, the telescopic frame 41 of the camera support frame 40 is adjusted to an appropriate height, and the handle 312 is rotated to drive the rotating shaft 31 and the moving pawl 311 to rotate, thereby realizing the angle adjustment of the camera support frame 40. The pawl 311 will automatically lock at the corresponding position of the internal gear 32 to ensure the stability of the camera without movement. The camera conducts shooting and recording, and its signal is transmitted to the display screen through wireless connection.

[0042] Embodiment 2

[0043] Reference Figures 1~10 Regarding the support member 10 in the first embodiment, it can also be designed as a hollow frustum with a height of 3 to 4 cm and diameters of 1 to 3 cm at both ends. A rubber ring is provided inside the frustum. The position of the rubber ring is usually on the side with a larger diameter of the support member 10 to better adapt to and fix fiber mechanical stimulation needles with different diameters. An expansion rod 20 is provided at the larger-diameter end, and the handheld rod of the fiber mechanical stimulation needle is slowly inserted through the side with a larger diameter of the support member 10. Due to the elasticity of the rubber ring, it will automatically adapt to the diameter of the handheld rod of the fiber mechanical stimulation needle and form a tight fit on the surface of the handheld rod of the fiber mechanical stimulation needle. This can effectively prevent the device from shaking or falling off during use.

[0044] Embodiment 3

[0045] Reference Figures 1~10 Regarding the telescopic frame 41 of the camera support frame 40 in the first embodiment, "C"-shaped grooves are provided at the bottom of the telescopic frame 41. The grooves are made of a material with certain elasticity and not easily deformed, such as synthetic rubber, etc. The notch of the groove faces downward, and polyurethane coatings, rubber coatings, polymer coatings, etc. are provided inside the notch diameter of the groove to increase friction.

[0046] During specific implementation, when it is necessary to install or fix the telescopic frame 41, the notch of the groove is aligned with the rotating shaft 31, and a certain pressure is applied to the telescopic frame 41 until the notch of the "C"-shaped groove completely coincides with the rotating shaft 31, so that it can be stably clamped on the rotating shaft 31. Such a design not only simplifies and speeds up the installation process, but also has a firm and reliable connection.

[0047] Embodiment 4

[0048] Reference Figures 1~10 Regarding the camera support frame 40 in the first embodiment, if the camera captures clearly and there is no need to adjust the height, it can also be replaced with a fixed frame 42 with a groove as in Embodiment 3 at the bottom. And at this time, the bottom of the fixed frame 42 and the bottom of the telescopic frame 41 have the same structure and can both be clamped on the rotating shaft 31. Removing the telescopic frame 41 and only installing the fixed frame 42 can reduce the weight of the device and increase flexibility.

For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
