Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a device for testing the effectiveness of plasma surgical equipment. Background Technology

[0002] In scenarios such as factory inspection and routine calibration of plasma surgical equipment, it is necessary to verify the two core functions of "cutting mode" and "coagulation mode". The verification process in the existing technology is as follows: Cutting mode verification: Relying on the surgical electrode to excite ion luminescence, the plasma effect is confirmed by wavelength measurement.

[0003] Current detection devices have technical flaws. Regarding the verification of cutting patterns, existing detection equipment lacks a dedicated light-shielding structure, and ambient light easily interferes with the wavelength probe, making it impossible to directly determine that the corresponding identification wavelength source is the plasma wavelength emitted by the plasma surgical device, resulting in unreliable experimental results. On the other hand, the brightness of plasma is extremely low, making direct observation and identification very difficult. During detection and recording, the main subject captured by the camera is not obvious, and during the adjustment of the camera, collisions can cause unstable imaging of the light, affecting the stability of light detection. Ultimately, the verification of the cutting pattern effect and the detection of data are inaccurate. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing detection devices are prone to interference from ambient light when verifying the device switching mode, making it impossible to directly detect the plasma wavelength emitted by the plasma surgical device. In addition, the light intensity is low during the detection process, and the recognition is extremely low when observed directly with the naked eye, which easily leads to misjudgment. The purpose is to set up an effect detection device for plasma devices to solve the above-mentioned technical problems.

[0005] This utility model provides a device for detecting the effect of plasma equipment, comprising: Plasma surgical equipment emits plasma outwards from the plasma head of the equipment. An excitation medium, positioned around the plasma surgical device, is used to excite internal substances to emit light through plasma; it includes a light-emitting region and a non-light-emitting region; the light-emitting region is a spherical area of ​​the excitation medium affected by the plasma, and the non-light-emitting region is an area unaffected by the plasma.

[0006] This also includes: The detection component is used to identify and detect the wavelength of the emitting region.

[0007] A light-shielding shell is placed around the excitation medium and outside the plasma surgical equipment to form a light-shielding environment, and is located below the plasma surgical equipment; the light-shielding shell has detection holes for cooperation with the detection components; The image acquisition component, located on one side of the light-shielding shell, is used to capture images of the excitation medium to obtain images of the excitation medium being excited by plasma to form luminescent areas where light is emitted and non-luminescent areas where light is not emitted.

[0008] Furthermore, the detection component is a wavelength detector, including a wavelength probe at the front end, which is oriented toward the luminescent region formed by plasma excitation within the excitation medium.

[0009] Furthermore, the detection aperture is finely adjusted according to the size of the wavelength probe to ensure that no ambient light leaks in after the wavelength probe is inserted; the detection aperture is equipped with an adjustable spherical bearing, which is fitted onto the wavelength probe.

[0010] Furthermore, the inner wall of the light-shielding shell is provided with an observation port for fixing the image acquisition component, which runs through the light-emitting observation surface.

[0011] Furthermore, the observation port is covered with an observation window, which is a black glass that allows light to pass through from the inside to the outside in one direction. The outside can observe the internal plasma equipment and the light-emitting area of ​​the excitation medium through the observation window.

[0012] Furthermore, the light-shielding shell is detachable; the light-shielding shell consists of three parts: a rotating cover and a rear fixing box. The rear fixing box is located at the rear of the plasma surgical device, and an opening is provided on the side closest to the rear of the plasma surgical device; when closed, the rotating cover completely seals the opening of the rear fixing box.

[0013] Furthermore, a rotating hinge is provided at the connection between one end of the rotating cover and the rear fixed box, and the rotating cover rotates to one side with the rotating hinge as the center point.

[0014] Furthermore, a guide rail assembly is provided below the light-shielding shell for moving the light-shielding shell back and forth, which is used to adjust the distance between the image acquisition component and the light-emitting area without opening the light-shielding shell.

[0015] Furthermore, the top of the light-shielding shell is provided with a pre-reserved moving strip hole for moving relative to the plasma surgical device; a bendable and straight rubber strip is provided along the moving strip hole to block the moving strip hole when the plasma surgical device moves along the moving strip hole while the light-shielding shell is moving, thus maintaining the light-shielding environment inside the light-shielding shell.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects: 1. The device isolates the influence of ambient light on the detection components through a light-shielding shell, allowing for simultaneous verification and detection of the plasma of the detection components without moving them. This eliminates irrelevant factors during the experiment and directly detects the wavelength of the plasma emitted by the plasma surgical equipment, obtaining accurate detection data. Furthermore, the use of the light-shielding shell amplifies the plasma equipment with low luminous intensity in the dark environment, increasing the discernibility and reducing misjudgments compared to conventional natural light environments.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0023] Example 1: A plasma surgical device effect detection device includes a plasma surgical device 1 for emitting plasma from its own plasma head to the surrounding area, an excitation medium 2, a detection component 5, a light-shielding shell 6, and an image acquisition component 9. The excitation medium 2 is placed around the plasma surgical device 1 and is used to excite the plasma to form a light-emitting region 3 and a non-light-emitting region 4. The light-emitting region 3 is a spherical area of ​​the excitation medium 2 affected by the plasma, and the non-light-emitting region 4 is an area unaffected by the plasma. The above-mentioned regions need to be directly observable from the side of the container. Therefore, the excitation medium 2 is loaded into a container with at least one transparent side, such as a beaker, and the container has an opening at the top so that the plasma surgical device 1 can be inserted into the excitation medium 2 through the opening. The detection component 5 is installed on the side of the light-shielding shell and is used to identify and detect the wavelength of the light-emitting area 3. The detected image is a spectrum with wavelength as the horizontal axis and light intensity as the vertical axis.

[0024] A light-shielding shell 6 is placed around the excitation medium 2, forming a light-shielding environment outside the plasma surgical device 1; a detection hole 7 is provided on the light-shielding shell for cooperation with the detection component 5. Image acquisition component 9 is set on one side of light shield 6 and is used to take pictures of excitation medium 2 to obtain images of excitation medium 2 being excited by plasma to form light-emitting area 3 and light-emitting area 4 not emitting light. Reference Figure 1 In some embodiments, the inner wall of the light-shielding shell 6 is provided with an observation port 11 for fixing the image acquisition component 9 through the light-emitting area 3. The image acquisition component 9 is installed through the observation port 11, so that the image acquisition component 9, the excitation medium 2 and the plasma surgical device 1 are on the same horizontal line. This ensures that the image acquisition component 9 can directly capture the true state of the light-emitting area 3 and the non-light-emitting area 4 through the observation port 11, and avoids image distortion caused by shooting angle deviation.

[0025] In some embodiments, the observation port 11 is covered with an observation window 12; the observation window 12 is a black glass that allows light to pass through from the inside to the outside in one direction, and the plasma device and the light-emitting area 3 of the excitation medium 2 can be observed from the outside through the observation window 12; the observation window 12 is made of black glass, and most of the ambient light from the outside is blocked. The dark environment formed inside the light-shielding shell 6 indirectly amplifies the light-emitting imaging effect of the plasma in the excitation medium 2, which is convenient and quick when the image acquisition component 9 is not installed or when it is only necessary to verify whether the plasma device is working properly.

[0026] In a preferred embodiment, the light-shielding shell 6 is detachable, including a rotating cover 13 and a rear fixing box 14. The rear fixing box 14 is detachably and fixedly disposed at the rear of the plasma surgical device 1. An opening 15 is provided on the side of the rear fixing box 14 near the rear of the plasma surgical device 1. When closed, the rotating cover 13 completely closes the opening 15 of the rear fixing box 14. Through the design of the rotating cover 13 and the rear fixing box 14, when installing the light-shielding shell 6, the plasma device enters the interior through the opening 15 of the light-shielding shell 6 until the top of the plasma device abuts and matches the notch on the top of the light-shielding shell 6, so that the observation port 11 can be aligned with the plasma head of the plasma device. At this time, the rotating cover 13 is rotated to close, and a dark environment is formed inside the light-shielding shell 6 after light shielding. Only the plasma device serves as the light source inside, and the wavelength probe of the detection component 5 only detects the light-emitting area 3, effectively controlling and excluding variables of the test environment. Furthermore, the detachable design of the light-shielding shell 6 facilitates the replacement of the plasma device, allowing for multiple tests with different plasma devices.

[0027] In some embodiments, a rotating hinge 16 is provided at the connection between one end of the rotating cover 13 and the rear fixing box 14. The rotating cover 13 rotates to one side with the rotating hinge 16 as the center point. The rotating hinge 16 is located on the top of the light-shielding shell 6. When closed, the rotating cover 13 opens upwards. After the light-shielding shell 6 and the plasma device are fixed, the rotating cover 13 automatically closes downwards to create an internal light-shielding environment.

[0028] In other embodiments, the rotating hinge 16 is installed on either the left or right side of the light-shielding shell 6, causing the rotating cover 13 to open laterally. Simultaneously, the notch on the top of the light-shielding shell 6 for accommodating the plasma surgical device 1 is located at the top of the opening 15 of the rear fixing box 14. When the rotating cover 13 is closed, the top of the rotating cover 13 abuts against the side of the plasma surgical device 1, completely surrounding the notch. In some embodiments, a guide rail assembly 8 is provided below the light-shielding shell 6 for moving the light-shielding shell 6 back and forth, which is used to adjust the distance between the image acquisition component 9 and the light-emitting observation surface; wherein the guide rail assembly 8 is a slider guide rail, including a straight guide rail and a slider that slides in the straight guide rail. The slider has a recessed hole in the center, and a post is provided at the bottom of the light-shielding shell 6. The post is inserted into the hole, and the slider moves back and forth in the straight guide rail, so that the light-shielding shell 6 is adjusted to move closer to or further away from the plasma device. The distance when it moves away is a reserved installation space for the image acquisition component 9. When it moves closer, the screen size of the image acquisition component 9 is adjusted to adapt to different image acquisition components 9.

[0029] In some embodiments, the notch at the top of the light-shielding shell 6 extends rearward along the top of the rear fixing box 14, serving as a movable slot 17 reserved for movement relative to the plasma surgical device 1. During the forward and backward movement of the light-shielding shell 6, it is necessary not only to maintain the internal light-shielding environment but also to reserve space for movement. Therefore, the notch at the top is extended to form the movable slot 17, which follows the same trajectory as the guide rail assembly 8. Several bendable and recoverable rubber strips 18 are provided along the slot 17, and all of these rubber strips 18 can provide light protection during the movement of the light-shielding shell 6. Cover the movable slot 17; when the light shield 6 moves along the guide rail assembly 8, because the plasma device is connected to an external power source, part of the plasma device is outside the light shield 6; several rubber strips 18 are closely arranged on the movable slot 17. When the light shield 6 moves back and forth along the guide rail assembly, and the plasma surgical device 1 moves along the movable slot 17 and lifts up part of the rubber strips 18, the rubber strips 18 adaptively bend upward and fit sideways, and at this time, they still have a partial blocking function; after the device moves, the rubber strips 18 return to a straight state and restore complete blocking of the movable slot 17.

[0030] Reference Figure 4 In a preferred embodiment, the detection component 5 is a wavelength detector, including a wavelength probe at the front end. The wavelength probe faces the light-emitting area 3 formed by plasma excitation within the excitation medium 2. The detection principle of the cutting mode of the plasma surgical device 1 in the prior art is that during the process of generating plasma by the electrodes of the plasma device in the ion solution, the charged particles located in the vapor sheath undergo various physical and chemical processes such as ionization, decomposition, and recombination under the combined action of the temperature field and the electric field, accompanied by energy radiation. The remaining energy is radiated out in the form of electromagnetic waves, emitting photons of characteristic frequencies. Among them, Na atoms with wavelengths of 580nm~600nm and H free radicals with wavelengths of 653.6nm have the most obvious emission spectra during the plasma discharge process. In the figure, the light intensity of the wavelengths of 550nm to 600nm is the most obvious. This is used to determine that these wavelengths appear during the plasma discharge process. Furthermore, the light with the same wavelength range and the same light intensity in the ambient light is excluded by the light shield 6. As a result, the wavelength probe cannot distinguish whether the light of the corresponding wavelength comes from the ambient light or the light of the plasma in the light-emitting area 3. Thus, it is concluded that the plasma device has generated a plasma effect and the cutting mode of the device is operating normally.

[0031] In some embodiments, the detection hole 7 is finely adjusted according to the size of the wavelength probe of the detection component 5 to ensure that no ambient light leaks in after the wavelength probe is inserted; the detection hole 7 is provided with an adjustable spherical bearing 10, which is sleeved on the wavelength probe; the spherical bearing 10 is used to flexibly adjust the orientation of the wavelength probe without moving the overall position of the detection component 5, and adjust it slightly to keep the orientation of the wavelength probe unchanged, so that the orientation will not be deviated due to equipment vibration or slight collision, thus ensuring the stability of the detection process; the outer ring of the spherical bearing 10 is fitted with an adaptively shrinkable rubber ring, so that while it is fixed to the side wall, the internal light-shielding environment is protected from ambient light leakage or the amount of leakage is minimal, so as not to affect the detection component 5's detection of obvious characteristic wavelengths.

[0032] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
