Description

Technical Field

[0001] This application relates to the field of microscope measurement technology, and in particular to an observation stage and microscope device. Background Technology

[0002] Digital microscopes are widely used in industrial production for product observation, including visual measurement and dimensional measurement. Currently, microscopes are used to observe the cross-section of the tips of catheters in medical devices to determine product quality.

[0003] The outer diameter of the balloon tip after folding, as well as its outer diameter and folding state after depressurization and recovery, are important performance characteristics of balloon catheters. During the balloon folding design process, detailed observation and dimensional measurement of the tip cross-section after depressurization and recovery are necessary to determine the product performance of the balloon catheter.

[0004] When observing and measuring the cross-section of the tip of catheter-like instruments, for destructible samples, they are sliced ​​and placed on a stage for observation; for indestructible samples, their cross-section can only be roughly aligned with the lens for observation. However, due to the small diameter, long length, and often curved nature of the tubes being measured, there are problems such as difficulty in focusing the lens and blurry sampling.

[0005] For balloon catheters, the following challenges exist during measurement: the tip of the balloon needs to be directly facing the optical lens, but the overall length of the balloon catheter is over 1m and the catheter is curved. During observation, the front of the catheter cannot be fixed, and even after the balloon is directly facing the lens, the tip may not be perpendicular to the lens, which will obstruct the measurement.

[0006] If the balloon catheter is held by hand for imaging, the imaging effect is poor. In addition, the catheter is very long and shakes when held for imaging. Furthermore, the hand holding the catheter will be included in the background of the image, making the overall effect more blurry and not conducive to measuring the cross-sectional dimensions of the balloon tip. Utility Model Content

[0007] Therefore, it is necessary to provide an observation stage and microscope device to address the problems of difficulty in clamping and damage to the catheter structure when observing the cross-section of catheter-type instruments. This device can reliably clamp the tube to be measured, so that the end of the tube to be measured is directly facing the optical lens, which facilitates cross-sectional observation of the end to be measured by the optical lens and ensures the accuracy of the observation results.

[0008] According to one aspect of the present invention, an observation stage is provided, used in a microscope apparatus, for clamping a tube to be measured. The observation stage includes:

[0009] The base has a first mounting hole that extends through the height direction;

[0010] A connecting pipe is provided in the first mounting hole along the height direction;

[0011] An iris mechanism is installed in the connecting tube. The tube to be measured can extend through the connecting tube and the iris mechanism so that the end of the tube to be measured is exposed in the connecting tube. The iris mechanism can open or close to release or clamp the tube to be measured.

[0012] In one embodiment of this application, the outer diameter of the connecting pipe is smaller than the inner diameter of the first mounting hole;

[0013] The observation platform also includes a flexible tube, which is disposed between the connecting tube and the first mounting hole, and is used to interference fit the connecting tube into the first mounting hole.

[0014] In one embodiment of this application, the flexible tube is made of rubber material;

[0015] And / or, the height dimension of the flexible tube is smaller than the height dimension of the first mounting hole;

[0016] And / or, the thickness of the flexible tube is greater than or equal to the distance between the outer wall of the connecting tube and the inner wall of the first mounting hole.

[0017] In one embodiment of this application, the connecting tube is made of polypropylene, thermoplastic polymer, polycarbonate, or polyetheretherketone.

[0018] And / or, the base is made of metal;

[0019] And / or, the iris recognition mechanism is made of polypropylene, thermoplastic polymer, polycarbonate or polyetheretherketone.

[0020] And / or, when there is one iris recognition mechanism, the iris recognition mechanism is located at the top of the connecting tube; when there are at least two iris recognition mechanisms, the at least two iris recognition mechanisms are spaced apart along the height direction.

[0021] In one embodiment of this application, the base has a first surface and a second surface arranged opposite to each other, the top end of the connecting tube protrudes from the first surface of the base, and the end of the tube to be measured is exposed on the first surface.

[0022] In one embodiment of this application, the base has a first surface and a second surface disposed opposite to each other, and the base also has a recessed receiving groove;

[0023] The receiving groove is located on the second surface and communicates with the first mounting hole. The receiving groove is used to receive part of the tube body to be measured.

[0024] In one embodiment of this application, the iris recognition mechanism includes a cover plate, a drive assembly, and a plurality of blades. The cover plate has a second mounting hole extending through the height direction and communicating with a connecting tube for the tube to be measured to pass through.

[0025] The drive assembly is movably mounted on the connecting pipe, the cover plate covers the drive assembly, multiple blades are arranged at intervals along the circumference of the cover plate, and the multiple blades are rotatably connected to the cover plate and the drive assembly respectively.

[0026] When the drive assembly moves relative to the connecting pipe and cover plate, it can drive multiple blades to move into or out of the second mounting hole to control the iris mechanism to close or open.

[0027] In one embodiment of this application, the drive assembly includes a turntable and a plurality of transmission links, the turntable being rotatably disposed between the connecting pipe and the cover plate;

[0028] Multiple transmission links are arranged at intervals along the circumference of the turntable. One end of each transmission link is rotatably connected to the turntable, and the other end is rotatably connected to the blade.

[0029] When the turntable rotates, it can drive the transmission linkage to rotate the corresponding blade relative to the cover plate, so that the blade can move into or out of the second mounting hole.

[0030] In one embodiment of this application, the edge of the blade has a first mating edge and a second mating edge. When the iris mechanism is closed, the first mating edge of the blade can fit against the second mating edge of the adjacent blade, so that multiple blades can block the second mounting hole.

[0031] And / or, the number of leaves is three to five;

[0032] And / or, the cover plate has multiple first guide portions, and the turntable has multiple second guide portions arranged at intervals along the circumference of the turntable. The multiple second guide portions are correspondingly provided with the multiple first guide portions and are installed in cooperation. When the turntable rotates, it is guided by the guiding cooperation between the second guide portions and the first guide portions. One of the first guide portions and the second guide portions is a guide protrusion, and the other is a guide arc groove.

[0033] According to another aspect of the present invention, a microscope apparatus is provided, comprising a stage, an optical lens, and an observation stage as described above.

[0034] The machine includes a support platform and a support frame. The support frame is set on the support platform along the height direction, and the observation table is set on the support frame for clamping the tube to be measured. There is a preset distance between the observation table and the surface of the support platform to accommodate the tube to be measured.

[0035] An optical lens is mounted on the machine tool and is used to measure the tube to be measured held in the observation table.

[0036] By adopting the above technical solution, this application has at least the following technical effects:

[0037] The observation stage and microscope apparatus of this application include an observation stage in which a connecting tube is disposed along the height direction in a first mounting hole in the base, and an iris mechanism disposed in the connecting tube. The iris mechanism can open or close. When the iris mechanism is open, the tube to be measured can extend through the connecting tube and the iris mechanism, so that the end of the tube to be measured can be exposed in the connecting tube and face the optical lens of the microscope apparatus. When the iris mechanism is closed, it can clamp the tube to be measured to fix it to the base.

[0038] The observation stage of this application uses an iris mechanism to fix the tube to be measured onto the base, with the measured end of the tube protruding from the iris mechanism and connecting tube, while the rest of the tube lies below the base. This ensures that even if the tube is long, the iris mechanism reliably secures it to the base, guaranteeing that the measured end faces the optical lens of the microscope, facilitating cross-sectional observation and dimensional measurement. The entire observation and measurement process does not require the user to hold the tube, ensuring the accuracy of the measurement results. Attached Figure Description

Detailed Implementation

[0048] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0049] Taking balloon catheters in medical devices as an example, the following difficulties exist during the measurement process: The tip of the balloon needs to be directly facing the optical lens, but the overall length of the balloon catheter is over 1 meter. When the conical part of the balloon catheter is facing upwards, the entire catheter is in a bent state, making it impossible to fix the front part of the catheter. Furthermore, even when the balloon is directly facing the lens, the tip may not be perpendicular to the lens, obstructing the measurement. Moreover, if the balloon catheter is held handheld for imaging, the image quality is poor. The catheter is long, and handheld imaging is prone to shaking. Additionally, the background around the balloon often includes fingers in the image, further blurring the overall image and making it difficult to measure the cross-sectional dimensions of the balloon tip.

[0050] See Figures 1 to 5 This application provides a novel observation platform 100. Figure 1 This is a schematic diagram of the observation platform 100 according to an embodiment of this application from one perspective. Figure 2 for Figure 1 The diagram shown is a schematic representation of the observation platform 100 from another perspective. Figure 3 for Figure 1 An exploded view of the observation platform 100 shown. Figure 4 for Figure 1 The top view of the observation platform 100 shown. Figure 5 for Figure 4 The observation platform 100 shown is a cross-sectional view along the AA direction.

[0051] The observation stage 100 is used in a microscope apparatus (not shown) and is an auxiliary tool used when observing samples under the microscope. Its main purpose is to support and fix the sample. In this application, the sample is a tube to be measured (not shown). Exemplarily, the tube to be measured is a medical catheter, such as a balloon catheter. Of course, in other embodiments of this application, the tube to be measured can also be other tubular components that require cross-sectional observation and dimensional measurement using a microscope apparatus. The following description uses a balloon catheter as an example of the tube to be measured.

[0052] To better illustrate the structure of the observation stage 100, the structure of the microscope apparatus will be briefly described first. The microscope apparatus includes a stage (not shown), an optical lens (not shown), and the observation stage 100 of this application. The stage includes a support platform (not shown) and a support frame (not shown). The support frame is disposed on the support platform and extends along the height direction. The height direction of this application is... Figure 1 and Figure 5 The vertical direction shown is the reference. The support platform can be placed on a surface such as an operating platform, desktop, or other surface.

[0053] The optical lens is mounted on the support frame of the machine tool and located above the support platform. The observation stage 100 is mounted on the support frame and located between the optical lens and the support platform. That is, the observation stage 100 is located below the optical lens and above the support platform. The observation stage 100 can clamp and fix the tube to be measured. There is a preset distance between the observation stage 100 and the support platform. After the observation stage 100 clamps the tube to be measured, the remaining part of the tube to be measured is accommodated between the support platform and the observation stage 100.

[0054] Understandably, the tube to be measured has a relatively long length, generally exceeding 1 meter. The end of the tube to be measured is the end to be measured, such as the tip of a balloon catheter. The tube to be measured passes through the observation platform 100 so that the end to be measured protrudes above the observation platform 100 and faces the optical lens. Then, the observation platform 100 can clamp and fix the tube to be measured so that the end to be measured is located between the observation platform 100 and the optical lens, while the rest of the tube is located below the observation platform 100, i.e., between the observation platform 100 and the support platform.

[0055] Subsequently, an optical lens can be used to observe and measure the cross-section of the end of the tube to be measured, in order to obtain relevant parameters of the cross-section. This allows for clear observation of the details of the edge of the end of the tube under test through the optical lens, making the observation and measurement of the tube more accurate and facilitating the assessment of the product quality.

[0056] It is worth noting that the focus of this application is on the structure of the observation stage 100 and how it clamps and fixes the tube to be measured. The structure and working principle of the machine tool and optical lens can be referred to the prior art, and will not be repeated here.

[0057] The observation stage 100 of this application can clamp and fix the tube to be measured so that the end of the tube to be measured is exposed on the observation stage 100, ensuring that the end of the tube to be measured is facing the optical lens of the microscope device, which facilitates the optical lens to observe and measure the cross-section and size of the end to be measured. Moreover, the entire observation, measurement and size measurement process does not require the user to hold the tube to be measured, ensuring the accuracy of the measurement results.

[0058] See Figures 1 to 5 In one embodiment, the observation platform 100 includes a base 110, a connecting tube 120, and an iris mechanism 130. The base 110 has a first mounting hole 111 extending through the height direction. The connecting tube 120 is disposed in the first mounting hole 111 along the height direction. The iris mechanism 130 is disposed in the connecting tube 120, and the tube to be measured can extend through the connecting tube 120 and the iris mechanism 130 so that the end of the tube to be measured is exposed in the connecting tube 120. The iris mechanism 130 can open or close to release or clamp the tube to be measured.

[0059] The base 110 is a component that supports and mounts the observation stage 100. The base 110 supports other components of the observation stage 100, allowing the observation stage 100 to be integrated into a single structure. Simultaneously, the base 110 also secures the entire observation stage 100; one edge of the base 110 can be mounted to the microscope apparatus's mounting platform, facilitating the installation of the observation stage 100. The base 110 has a through-hole 111 along its height direction. Figure 1 and Figure 5 The vertical direction is shown in the diagram.

[0060] The connecting tube 120 is a component that supports the iris mechanism 130 and installs it onto the base 110. The connecting tube 120 is installed in the first mounting hole 111. The axial direction of the connecting tube 120 is the height direction. The connecting tube 120 extends along the axial direction. The iris mechanism 130 is disposed on the connecting tube 120. The iris mechanism 130 is a component that clamps and fixes the tube to be measured. When the iris mechanism 130 moves, it can open or close to release or clamp the tube to be measured.

[0061] When the iris mechanism 130 opens, the end of the tube to be measured extends from bottom to top through the connecting tube 120 and the iris mechanism 130. At this time, the end to be measured protrudes above the connecting tube 120 and the base 110, and extends towards the optical lens. Subsequently, the iris mechanism 130 gradually closes. At this time, the iris mechanism 130 can clamp the tube to be measured to hold and fix the tube to be measured, so that the end of the tube to be measured faces the optical lens.

[0062] Understandably, the end to be measured is a short section at the top of the tube to be measured. Taking a balloon catheter as an example, the end to be measured is the length of the tip of the balloon catheter and the balloon portion. Because the length of the tube to be measured is relatively long, even if the tube to be measured is in a curved state, the iris mechanism 130 clamps and fixes the tube to be measured, and the connecting tube 120 guides the tube to be measured, ensuring that the curved part of the tube to be measured is located between the base 110 and the support platform, thus ensuring that the end to be measured above the iris mechanism 130 extends along the height direction.

[0063] That is, by clamping and fixing the tube to be measured through the iris mechanism 130, and guiding the tube to be measured through the connecting tube 120, the portion of the tube to be measured protruding above the base 110 can be kept basically vertical (perpendicular to the base 110), thus ensuring that the end to be measured is directly facing the optical lens. In this way, when using the optical lens to observe and measure the cross-section and dimensions of the end to be measured, the end to be measured will not interfere with the measurement part, and the details of the edge of the end to be measured can be clearly observed through the optical lens, thereby making the observation and measurement of the cross-section and dimensions of the tube to be measured more accurate, so as to facilitate the judgment of the product quality of the tube to be measured.

[0064] In the above embodiment, the observation platform 100 uses an iris mechanism 130 to fix the tube to be measured onto the base 110, with the end of the tube to be measured exposed between the iris mechanism 130 and the connecting tube 120, while the rest of the tube is located below the base 110. Thus, even if the tube to be measured is long, the iris mechanism 130 reliably fixes it to the base 110, ensuring that the end of the tube to be measured faces the optical lens of the microscope device. This facilitates cross-sectional observation and dimensional measurement of the end by the optical lens. Furthermore, the entire observation, measurement, and dimensional measurement process does not require the user to hold the tube, ensuring the accuracy of the measurement results.

[0065] In one embodiment, the base 110 is made of metal. This ensures the structural strength of the base 110 and improves its supporting performance. Optionally, the base 110 is made of stainless steel, copper, or other materials. In this embodiment, the base 110 is rectangular. Of course, in other embodiments of this application, the base 110 can also be square, circular, or other shapes, as long as it can support and install the various components.

[0066] See Figure 1 and Figure 2 In one embodiment, the base 110 has a first surface 112 and a second surface 113 facing each other. The top end of the connecting tube 120 protrudes from the first surface 112 of the base 110, and the end of the tube to be measured is exposed on the first surface 112. The upper surface of the base 110, which is the surface of the base 110 facing the optical lens, is the first surface 112, and the lower surface of the base 110, which is the surface of the base 110 facing the support platform, is the second surface 113.

[0067] The first mounting hole 111 penetrates the first surface 112 and the second surface 113 of the base 110 along the height direction, that is, the first mounting hole 111 penetrates the upper surface and the lower surface of the base 110 along the height direction, and the connecting tube 120 is installed in the first mounting hole 111. In this way, the tube to be measured can pass through the first mounting hole 111 and extend into the connecting tube 120, and then extend through the iris mechanism 130.

[0068] Furthermore, after the connecting pipe 120 is installed in the first mounting hole 111, the connecting pipe 120 protrudes from the first surface 112 of the base 110. That is, the dimension of the connecting pipe 120 in the height direction is larger than the dimension of the base 110 in the height direction, so that the connecting pipe 120 has a certain length in the height direction.

[0069] In this way, the connecting tube 120 can guide the tube body to be measured so that the part of the tube body to be measured extending out of the iris mechanism 130 remains perpendicular to the base 110, thereby ensuring that the end to be measured is facing the optical lens, which facilitates the optical lens to observe and measure the cross-section and size of the end to be measured.

[0070] See Figures 1 to 3 , Figure 5 In one embodiment, the base 110 has a first surface 112 and a second surface 113 facing away from each other, and the base 110 also has a recessed receiving groove 114. The receiving groove 114 is located on the second surface 113 and communicates with the first mounting hole 111. The receiving groove 114 is used to receive a portion of the tube body to be measured.

[0071] In other words, the lower surface of the base 110 has a recessed receiving groove 114. The receiving groove 114 connects to the first mounting hole 111 and also connects to the space below the base 110. At the same time, the receiving groove 114 extends through one end of the base 110. In this way, when the portion of the tube to be measured below the base 110 is bent, the receiving groove 114 can accommodate part of the tube to be measured, so that the tube to be measured can be installed into the connecting pipe 120.

[0072] In one embodiment, the connecting tube 120 is made of polypropylene (PP), thermoplastic polymer (Acrylonitrile Butadiene Styrene, ABS), polycarbonate (PC), or polyetheretherketone (PEEK). The connecting tube 120 connects the iris mechanism 130 to the base 110, so that the iris mechanism 130 and the base 110 form an integral structure.

[0073] In one embodiment, the iris recognition mechanism 130 is made of polypropylene (PP), thermoplastic polymer (ABS), polycarbonate (PC), or polyetheretherketone (PEEK). The iris recognition mechanism 130 can clamp and fix the tube to be measured.

[0074] See Figure 1 , Figures 3 to 5 In one embodiment of this application, there is one iris recognition mechanism 130, which is located at the top of the connecting tube 120. That is, one iris recognition mechanism 130 is located at the top of the connecting tube 120. After the tube to be measured extends through the connecting tube 120 and the iris recognition mechanism 130, the tube to be measured is clamped and fixed by the iris recognition mechanism 130, so that the end of the tube to be measured is exposed in the connecting tube 120.

[0075] Of course, when there is only one iris mechanism 130, the iris mechanism 130 can also be located at the bottom of the connecting tube 120 or at other positions, as long as it is convenient for the iris mechanism 130 to clamp or release the tube to be measured. When the iris mechanism 130 is located in the middle of the connecting tube 120, the connecting tube 120 can be divided into two sections so that the iris mechanism 130 is exposed in the connecting tube 120, making it convenient for the user to control the opening or closing of the iris mechanism 130.

[0076] Of course, in other embodiments of this application, when the number of iris mechanisms 130 is at least two, the at least two iris mechanisms 130 are spaced apart along the height direction. For example, two iris mechanisms 130 can be placed above and below the connecting tube 120. The reliability of clamping and fixing the tube to be measured can be improved by using two iris mechanisms 130, preventing the position of the tube to be measured from shifting. Of course, the number of iris mechanisms 130 can also be other.

[0077] See Figure 3 , Figure 5 and Figure 6 In one embodiment, the outer diameter of the connecting pipe 120 is smaller than the inner diameter of the first mounting hole 111. The observation platform 100 also includes a flexible pipe 140, which is disposed between the connecting pipe 120 and the first mounting hole 111 and is used to interference fit the connecting pipe 120 into the first mounting hole 111. Figure 6 for Figure 5 A magnified view of the observation platform 100 at point B.

[0078] After the connecting pipe 120 is installed into the first mounting hole 111, there is a certain gap between the outer wall of the connecting pipe 120 and the inner wall of the first mounting hole 111. After the flexible pipe 140 is placed between the connecting pipe 120 and the first mounting hole 111, the flexible pipe 140 can fill the gap between the connecting pipe 120 and the first mounting hole 111, so that the connecting pipe 120 is interference-fitted into the first mounting hole 111. By using the compression state between the three, the connecting pipe 120 is installed onto the base 110.

[0079] Furthermore, since the flexible tube 140 has a certain compressibility, the connecting tube 120 can have a certain degree of freedom. If the iris mechanism 130 clamps the tube to be measured and the end to be measured has a small tilt angle relative to the base 110, the connecting tube 120 can be operated to have a certain tilt angle relative to the base 110 through the flexible tube 140 to adapt to the tilt of the end to be measured.

[0080] In other words, after the iris mechanism 130 clamps and fixes the tube to be measured, if the end to be measured is not directly facing the optical lens, the flexible tube 140, due to its compressible nature, can be slightly adjusted in position by the cooperation of the connecting tube 120 and the flexible tube 140, so that the end to be measured of the tube is directly facing the optical lens. If the angle of deviation of the end to be measured is large, the tube to be measured clamped by the iris mechanism 130 needs to be readjusted.

[0081] In one embodiment, the flexible tube 140 is made of rubber material. That is, the flexible tube 140 is a rubber tube. The rubber tube fills the gap between the connecting tube 120 and the first mounting hole 111. Utilizing the compressibility of the rubber tube, the connecting tube 120 is mounted on the base 110, and at the same time, the position of the end to be measured can be finely adjusted so that the end to be measured is directly facing the optical lens.

[0082] See Figure 3 , Figure 5 and Figure 6 In one embodiment, the height of the flexible tube 140 is smaller than the height of the first mounting hole 111. That is, the height of the flexible tube 140 is smaller. In this way, the flexible tube 140 can cover the smaller height of the outer wall of the connecting tube 120, and while installing the connecting tube 120 onto the base 110, it is also convenient for the connecting tube 120 to tilt relative to the base 110, so as to make slight adjustments to the position of the end to be measured.

[0083] See Figure 3 , Figure 5 and Figure 6 In one embodiment, the thickness of the flexible tube 140 is greater than or equal to the distance between the outer wall of the connecting tube 120 and the inner wall of the first mounting hole 111. This allows the flexible tube 140 to be interference-fitted between the connecting tube 120 and the first mounting hole 111, giving the flexible tube 140 a compressible characteristic for mounting the connecting tube 120 to the base 110 and facilitating adjustment of the connecting tube 120's position.

[0084] See Figure 1 , Figure 3 , Figure 7 and Figure 8 In one embodiment, the iris recognition mechanism 130 includes a cover plate 131, a drive assembly 132, and a plurality of blades 133. The cover plate 131 has a second mounting hole 1311 extending through the height direction, which communicates with a connecting pipe 120 for the tube to be measured to pass through. The drive assembly 132 is movably disposed on the connecting pipe 120, and the cover plate 131 covers the drive assembly 132. The plurality of blades 133 are arranged circumferentially spaced along the cover plate 131, and the plurality of blades 133 are rotatably connected to the cover plate 131 and the drive assembly 132, respectively. When the drive assembly 132 moves relative to the connecting pipe 120 and the cover plate 131, it can drive the plurality of blades 133 to move into or out of the second mounting hole 1311 to control the iris recognition mechanism 130 to close or open. Figure 7 for Figure 3 The diagram shown is a schematic representation of the iris mechanism 130 in the observation platform 100 from one perspective. Figure 8 for Figure 7 A schematic diagram of the iris recognition mechanism 130 from another perspective.

[0085] The cover plate 131 is the upper cover of the iris recognition mechanism 130. The middle region of the cover plate 131 has a second mounting hole 1311 that extends through the height direction. The second mounting hole 1311 is coaxially arranged with the connecting tube 120 and communicates with the inner cavity of the connecting tube 120. The end of the tube to be measured can pass through the connecting tube 120 and the second mounting hole 1311 of the cover plate 131 to protrude, so that the end to be measured is exposed on the first surface 112 of the base 110.

[0086] Multiple blades 133 are rotatably connected to a cover plate 131, and are also rotatably connected to a drive assembly 132. The drive assembly 132 is movably disposed between the connecting pipe 120 and the cover plate 131. When the drive assembly 132 moves, it can drive the blades 133 to rotate relative to the cover plate 131. As the blades 133 rotate, they can move into or out of the second mounting hole 1311. When the multiple blades 133 move into the second mounting hole 1311, they can block the second mounting hole 1311 to close the iris mechanism 130. When the multiple blades 133 move out of the second mounting hole 1311, the second mounting hole 1311 is exposed to open the iris mechanism 130.

[0087] When installing the tube to be measured, the drive assembly 132 drives multiple blades 133 to move out of the second mounting hole 1311, so that the iris mechanism 130 opens. At this time, the end of the tube to be measured can extend through the connecting tube 120 and the second mounting hole 1311. Subsequently, the drive assembly 132 drives multiple blades 133 to rotate, so that multiple blades 133 move into the second mounting hole 1311. At this time, multiple blades 133 can clamp the tube to be measured, so that the end to be measured faces the optical lens, thereby achieving clamping and fixing of the tube to be measured.

[0088] Furthermore, after the multiple blades 133 clamp the tube to be measured, the multiple blades 133 partially block the second mounting hole 1311. In this way, the multiple blades 133 can limit excess light from passing through the second mounting hole 1311, acting as an aperture to prevent the optical lens from capturing unwanted parts, which helps with focusing, ensures the accuracy of the imaging results of the optical lens, facilitates the measurement of cross-sectional dimensions, and improves measurement efficiency.

[0089] In other words, after multiple blades 133 clamp the tube to be measured, they can block light from passing through the edge of the tube, facilitating the focusing of the optical lens. This allows the optical lens to accurately observe and measure the cross-section and dimensions of the end being measured, clearly observing edge details and ensuring more accurate dimensional measurements.

[0090] See Figure 8In one embodiment, a plurality of blades 133 are disposed below the cover plate 131. That is, the plurality of blades 133 are located between the cover plate 131 and the connecting pipe 120, and clamp the tube to be measured between the connecting pipe 120 and the cover plate 131.

[0091] See Figure 7 and Figure 8 In one embodiment, the edge of the blade 133 has a first mating edge 1331 and a second mating edge 1332. When the iris mechanism 130 is closed, the first mating edge 1331 of the blade 133 can fit against the second mating edge 1332 of the adjacent blade 133 so that the multiple blades 133 can block the second mounting hole 1311.

[0092] In other words, the blade 133 is roughly in the shape of a leaf. Multiple blades 133 can be spliced ​​together to form a circle, so as to effectively cover the second mounting hole 1311. Figure 7 The image shows multiple blades 133 partially open. When the multiple blades 133 are fully closed, the first mating part between adjacent blades 133 fits against the second mating edge 1332 and can completely cover the second mounting hole 1311.

[0093] In one embodiment, the number of blades 133 is three to five. In this embodiment, the number of blades 133 is five. The five blades 133 are arranged to form a complete circle to cover the second mounting hole 1311. Of course, in other embodiments of this application, the number of blades 133 may also be three, four, or other numbers.

[0094] Understandably, the number of blades 133 can also be selected according to the catheter to be measured. When the catheter to be measured is a balloon catheter, the balloon of the balloon catheter is a three-wing fold or a five-wing fold, and a corresponding number of blades 133 are set to clamp the corresponding balloon catheter to ensure the reliability of the balloon catheter clamping and fixing.

[0095] In this application, after the iris mechanism 130 clamps the balloon catheter, the gap between adjacent blades 133 is adjusted by the outer diameter of the balloon. This can both clamp and fix the balloon catheter so that the tip of the balloon catheter faces the optical lens, and restrict the passage of light by blocking the blades 133, thus acting as an aperture and helping with focusing.

[0096] See Figure 8In one embodiment, the drive assembly 132 includes a turntable 1321 and a plurality of transmission links 1322. The turntable 1321 is rotatably disposed between the connecting pipe 120 and the cover plate 131. The plurality of transmission links 1322 are arranged circumferentially spaced along the turntable 1321. One end of each transmission link 1322 is rotatably connected to the turntable 1321, and the other end is rotatably connected to a blade 133. When the turntable 1321 rotates, it can drive the transmission links 1322 to rotate the corresponding blade 133 relative to the cover plate 131, so that the blade 133 can move into or out of the second mounting hole 1311.

[0097] A turntable 1321 is rotatably mounted on top of the connecting pipe 120, and a cover plate 131 is placed over the turntable 1321. The cover plate 131 is a stationary component, while the turntable 1321 can rotate relative to the connecting pipe 120. Each transmission link 1322 is curved and extends radially. One end of each transmission link 1322 is rotatably connected to the turntable 1321, and the other end is rotatably connected to the blade 133.

[0098] When the turntable 1321 rotates relative to the connecting pipe 120 and the cover plate 131, the turntable 1321 can drive the transmission link 1322 to move, and the transmission link 1322 can push the blade 133 to rotate around the cover plate 131, so that the blade 133 moves into or out of the second mounting hole 1311. Figure 8 As shown, turntable 1321 is in Figure 8 When rotated counterclockwise in the indicated direction, the turntable 1321 can drive the transmission linkage 1322 to move the blade 133 into the second mounting hole 1311. Figure 8 When rotated clockwise in the indicated direction, the turntable 1321 can drive the transmission link 1322 to move the blade 133 out of the second mounting hole 1311.

[0099] See Figure 8 In one embodiment, the cover plate 131 has a plurality of first guide portions 1312, and the turntable 1321 has a plurality of second guide portions 13211 arranged at intervals along the circumference of the turntable 1321. The plurality of second guide portions 13211 are correspondingly provided with the plurality of first guide portions 1312 and are installed in cooperation. When the turntable 1321 rotates, it is guided by the guiding cooperation of the second guide portions 13211 and the first guide portions 1312. One of the first guide portions 1312 and the second guide portions 13211 is a guide protrusion and the other is a guide arc groove.

[0100] The cooperation of the first guide part 1312 and the second guide part 13211 can guide the rotation of the turntable 1321 relative to the cover plate 131 and the connecting pipe 120, so as to ensure that the rotation trajectory of the turntable 1321 is accurate, thereby accurately driving the blade 133 to move into or out of the second mounting hole 1311.

[0101] In this embodiment, the first guide portion 1312 is a guide protrusion, and the second guide portion 13211 is a guide arc groove disposed on the turntable 1321. Of course, in other embodiments of this application, the positions of the guide protrusion and the guide arc groove can also be interchanged, that is, the first guide portion 1312 is a guide arc groove, and the second guide portion 13211 is a guide protrusion.

[0102] The observation stage 100 of this application can release and clamp the tube to be measured by opening or closing the iris mechanism 130. After the iris mechanism 130 clamps the tube to be measured, it can fix the tube to be measured so that the end of the tube to be measured is located between the base 110 and the optical lens, which facilitates the alignment of the end to be measured with the optical lens, and thus facilitates the optical lens to observe and measure the cross-section and size of the end to be measured.

[0103] In this way, even if the length of the tube to be measured is long, the iris mechanism 130 fixes the tube to be measured and guides it through the connecting tube 120, so that the tube to be measured can be reliably fixed to the base 110. This ensures that the end of the tube to be measured is facing the optical lens of the microscope device, which facilitates the optical lens to observe and measure the cross-section and size of the end to be measured. Moreover, the entire observation, measurement and size measurement process does not require the user to hold the tube to be measured, thus ensuring the accuracy of the measurement results.

[0104] Furthermore, the flexible tube 140 is interference-fitted between the connecting tube 120 and the first mounting hole 111, giving the flexible tube 140 a certain degree of compressibility. In this way, the flexible tube 140 can facilitate the installation of the connecting tube 120 onto the base 110, while also allowing the connecting tube 120 a certain degree of freedom, so that its position can be slightly adjusted so that the end of the tube to be measured is directly facing the optical lens.

[0105] Simultaneously, the iris mechanism 130 uses a drive assembly 132 to drive multiple blades 133 to move, causing the blades 133 to move into or out of the second mounting hole 1311. This closes or opens the blades 133, thereby closing or opening the iris mechanism 130, achieving the clamping or release of the tube to be measured. After the multiple blades 133 clamp the tube to be measured, they partially block the second mounting hole 1311 to limit excess light from passing through it, acting as an aperture. This aids in focusing, ensures accurate imaging results from the optical lens, facilitates cross-sectional dimension measurement, and improves measurement efficiency.

[0106] This application also provides a microscope apparatus, including a machine base, an optical lens, and an observation stage 100 as described in any of the above embodiments. The machine base includes a support platform and a support frame, the support frame being disposed on the support platform along the height direction, and the observation stage 100 being disposed on the support frame for holding a tube to be measured. A predetermined distance exists between the observation stage 100 and the surface of the support platform to accommodate the tube to be measured. The optical lens is disposed on the machine base for measuring the tube to be measured held by the observation stage 100.

[0107] The microscope device of this application, employing the observation stage 100 of the above embodiment, is unaffected by the length of the tube to be measured. It enables the clamping and fixing of the tube, ensuring that the end of the tube to be measured faces the optical lens, facilitating cross-sectional observation and dimensional measurement of the end. The entire observation, measurement, and dimensional measurement process does not require the user to hold the tube, ensuring the accuracy of the measurement results.
