Abstract

A positioning mechanism and pancreatic tissue locator, relating to the field of medical device technology, are disclosed for positioning glass petri dishes. The glass petri dish has a spherical bottom surface. The positioning mechanism includes a positioning strip and a tension strip. The tension strip is fixed to the outer surface of the positioning strip, and its two ends are connected to limit the distance between them. By adjusting the connection position of the two ends of the tension strip, the size of the positioning area enclosed by the positioning strip can be adjusted. The positioning strip is used to contact the spherical bottom surface, and the positioning area is used to avoid contact with the glass petri dish.

Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a positioning mechanism and a pancreatic tissue locator. Background Technology

[0002] During EUS-FNA (ultrasound biopsy), because the puncture needle is very thin and pancreatic tissue needs to be pierced through multiple layers (such as tissue, muscle, mucosa, and skin), the obtained tissue often contains a large amount of blood or other substances. To better locate usable pancreatic tissue, a petri dish containing a liquid base and a puncture strip needs to be placed on a lamp for illumination. Currently, the lamp surface is flat, while the glass petri dish is placed on the convex surface of the lamp. This point contact between the convex surface and the flat surface results in poor stability, making the glass petri dish particularly prone to slipping or spilling during rinsing and specimen collection, thus affecting normal operation. Utility Model Content

[0003] The purpose of this invention is to provide a positioning mechanism and a pancreatic tissue locator, which can improve the stability of the combination of the glass petri dish and the illumination lamp, making it less likely for the glass petri dish to move relative to the illumination lamp during rinsing and specimen collection, and ensuring safe and reliable operation.

[0004] The embodiments of this utility model can be implemented as follows:

[0005] In a first aspect, this utility model provides a positioning mechanism for positioning a glass dish, the glass dish having a spherical bottom surface, comprising:

[0006] A positioning strip and an elastic strip are provided. The elastic strip is fixed to the outer surface of the positioning strip, and the two ends of the elastic strip are connected to limit the two ends of the positioning strip from moving away from each other. By adjusting the connection position of the two ends of the elastic strip, the size of the positioning area enclosed by the positioning strip can be adjusted.

[0007] The positioning strip is used to contact the bottom spherical surface, and the positioning area is used to avoid the glass surface dish.

[0008] In an optional embodiment, the elastic strip includes a strip body, a first adhesive body, and a second adhesive body; both the first adhesive body and the second adhesive body are fixed to the strip body, and the first adhesive body is used to bond and fix it to the second adhesive body; the strip body is fixed to the outside of the positioning strip.

[0009] Based on the above solution, when it is necessary to adjust the tightness of the elastic strip, the first adhesive body and the second adhesive body are separated. Then, the relative positions of the first adhesive body and the second adhesive body are adjusted according to the diameter of the lamp surface, and the first adhesive body and the second adhesive body are bonded together. The elastic strip can be consistent with the outer diameter of the lamp surface, so as to fit with the lamp cover around the lamp surface. This ensures that the lighting effect is not affected, improves stability, and is easy to operate.

[0010] In an optional embodiment, the first adhesive and the second adhesive are configured as a mutually cooperating Velcro assembly.

[0011] Based on the above solution, the structure is simple, it can be purchased directly, it can be reused multiple times, and the cost is low.

[0012] In an optional implementation, the positioning strip is configured as a hollow structure.

[0013] Based on the above solution, the positioning strip structure is lightweight, requires less material, has low cost, and good light transmittance.

[0014] In an optional embodiment, the positioning strip is configured as a light-transmitting element.

[0015] Based on the above solution, the positioning strip is less likely to block the light after the lighting is turned on.

[0016] In an optional embodiment, the positioning strip has an inner side for enclosing the positioning area, the inner side including a first inclined surface and a second inclined surface connected together, the first inclined surface and the second inclined surface having opposite inclination directions and different inclination angles.

[0017] Based on the above scheme, by setting the first and second inclined surfaces, when the positioning strip is formed into an arc or ring, both the first and second inclined surfaces can independently form a conical surface, which can better fit with the bottom spherical surface of the glass surface dish. Furthermore, the first or second inclined surface can be selected according to the needs to adapt to the positioning of glass surface dishes of different sizes, making it flexible and widely applicable.

[0018] In an optional embodiment, the positioning strip and the elastic strip are fixedly connected by an adhesive method.

[0019] Based on the above solution, the connection method between the positioning strip and the elastic strip is simple and reliable.

[0020] In an optional embodiment, the positioning strip has a first side and a second side in its width direction, and the elastic strip is located between the first side and the second side.

[0021] Based on the above solution, the elastic strip is blocked by the positioning strip, making it difficult for the glass surface dish to come into direct contact with the elastic strip.

[0022] In an optional embodiment, both the first side and the second side are provided with outward-folded edges.

[0023] Based on the above solution, the positioning strip can better cover the elastic strip by folding the edge.

[0024] Secondly, this utility model provides a pancreatic tissue locator, comprising:

[0025] The lighting lamp and the positioning mechanism described in any of the foregoing embodiments; the positioning mechanism is placed on the lighting lamp, and the positioning strip of the positioning mechanism is used to position the glass surface dish.

[0026] The advantages of the positioning mechanism and pancreatic tissue locating device provided in this embodiment of the invention include:

[0027] In summary, the positioning mechanism provided in this embodiment, when in use, first lay the lamp flat with the lamp surface facing upwards, ensuring the lamp's position is stable. Then, adjust the connection positions of the two ends of the elastic strip according to the size of the lamp surface, so that the outer diameter of the annular structure formed by the elastic strip is approximately the same as the diameter of the lamp surface. Place the elastic strip on the lamp surface, with the outer periphery of the elastic strip fitting against the lampshade walls around the lamp surface. At this point, the adjustment of the positioning mechanism is complete, and the positioning strip, constrained by the elastic strip, forms an annular or arc-shaped strip, forming a positioning area for placing the glass petri dish. This completes the assembly of the positioning mechanism and the lamp. Finally, place the glass petri dish to be processed on top of the positioning mechanism, with the bottom spherical surface of the glass petri dish facing downwards, located within the positioning area. After the glass petri dish is placed, the bottom spherical surface contacts the upper edge of the positioning strip, positioning the glass petri dish. In this way, the glass petri dish is stably positioned on the lamp surface, preventing it from moving relative to the lamp during rinsing and specimen collection, ensuring safe and reliable operation.

Detailed Implementation

[0035] In related technologies, when processing glass petri dishes 003, the bottom spherical surface 031 of the glass petri dish 003 is generally placed directly on the lamp surface 021 of the illumination lamp 002, with the lamp surface 021 facing upwards and lying flat, before the glass petri dish 003 is processed. During this process, because the lamp surface 021 is flat, the spherical convex surface and the flat surface are in point contact, resulting in poor stability. The glass petri dish 003 is particularly prone to slipping or spilling during rinsing and specimen collection, thus affecting normal operation.

[0036] To address the aforementioned problems, this utility model provides a positioning mechanism 001, which can improve the stability of the glass petri dish 003 in conjunction with the lighting lamp 002, thereby improving the problem that the glass petri dish 003 is particularly prone to slipping or spilling during the rinsing and specimen collection process.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0041] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0042] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0043] Please combine Figures 1-4 This embodiment provides a positioning mechanism 001 for positioning a glass dish 003, wherein the glass dish 003 has a bottom spherical surface 031, and the positioning mechanism 001 includes:

[0044] Positioning strip 100 and tension strip 200, tension strip 200 is fixed on the outer surface of positioning strip 100, and the two ends of tension strip 200 are connected to limit the two ends of positioning strip 100 from moving away from each other; by adjusting the connection position of the two ends of tension strip 200, the size of positioning area 101 enclosed by positioning strip 100 can be adjusted.

[0045] The positioning strip 100 is used to contact the bottom spherical surface 031, and the positioning area 101 is used to avoid the glass surface dish 003.

[0046] As described above, the positioning mechanism 001 provided in this embodiment is used as follows:

[0047] In use, first lay the light 002 flat with its lamp surface 021 facing upwards, ensuring the light 002 is in a stable position. Then, adjust the connection positions of the two ends of the elastic strip 200 according to the size of the lamp surface 021, so that the outer diameter of the annular structure formed by the elastic strip 200 is approximately the same as the diameter of the lamp surface 021. Place the elastic strip 200 on the lamp surface 021, ensuring that the outer circumference of the elastic strip is flush against the walls of the lampshade 022 around the lamp surface 021. At this point, the positioning mechanism 001 is adjusted, and the positioning strip 100, constrained by the elastic strip 200, forms an annular or arc-shaped strip, forming the positioning area 101 for placing the glass dish 003. This completes the assembly of the positioning mechanism 001 and the light 002. Finally, the glass petri dish 003 to be processed is placed above the positioning mechanism 001, with the bottom spherical surface 031 of the glass petri dish 003 facing downwards and located in the positioning area 101. After the glass petri dish 003 is placed, the bottom spherical surface 031 contacts the upper edge of the positioning strip 100, and the glass petri dish 003 is positioned by the positioning strip 100. In this way, the glass petri dish 003 is stably positioned on the lamp surface 021 of the illumination lamp 002. During the rinsing and specimen collection processes, the glass petri dish 003 is not easy to move relative to the illumination lamp 002, and the operation is safe and reliable.

[0048] The following embodiments illustrate the details of the positioning mechanism 001 of this application by way of example.

[0049] Please combine Figures 1-4 In this embodiment, optionally, the elastic strip 200 includes a strip body 210, a first adhesive body 220 and a second adhesive body 230; both the first adhesive body 220 and the second adhesive body 230 are fixed on the strip body 210, and the first adhesive body 220 is used to bond and fix with the second adhesive body 230; the strip body 210 is fixed on the outside of the positioning strip 100.

[0050] When it is necessary to adjust the tightness of the elastic strip 200, separate the first adhesive body 220 and the second adhesive body 230. Then, adjust the relative positions of the first adhesive body 220 and the second adhesive body 230 according to the diameter of the lamp surface 021 of the lighting lamp 002, and then bond the first adhesive body 220 and the second adhesive body 230 together. The elastic strip 200 can be consistent with the outer diameter of the lamp surface 021, so as to fit with the lamp cover 022 around the lamp surface 021. This ensures that the lighting effect is not affected, improves stability, and is easy to operate.

[0051] Optionally, the first adhesive body 220 and the second adhesive body 230 are configured as mutually cooperating hook and loop fastener components. Hook and loop fasteners have a simple structure, are readily available, can be reused multiple times, and are low in cost.

[0052] It should be understood that the strip body 210 can be a rectangular strip, and the strip body 210 can be made of materials such as plastic, which has a certain degree of deformation capability and is not easily bent or damaged. Furthermore, the first adhesive body 220 on the strip body 210 can be located on its inner surface, and correspondingly, the second adhesive body 230 on the strip body 210 can be located on its outer surface. When adjusting the diameter of the tension strip 200, the first adhesive body 220 is adjusted to be outside the second adhesive body 230, and then the set length can be adhered.

[0053] In this embodiment, optionally, the positioning strip 100 is configured as a hollow structure. The positioning strip 100 is lightweight, requires less material, has low cost, and good light transmittance.

[0054] Furthermore, the positioning strip 100 is designed to be light-transmitting. When the lighting lamp 002 is turned on, the positioning strip 100 will not easily block the light.

[0055] It should be noted that the positioning strip 100 can be made of plastic, which is easy to mold and has a certain degree of deformation capability, making it less prone to bending and damage.

[0056] In this embodiment, optionally, the positioning strip 100 has an inner side for forming the positioning area 101. The inner side includes a first inclined surface 110 and a second inclined surface 120 connected to each other. The first inclined surface 110 and the second inclined surface 120 have opposite inclination directions and different inclination angles.

[0057] This design, by setting the first inclined surface 110 and the second inclined surface 120, allows both the first inclined surface 110 and the second inclined surface 120 to independently form a conical surface when the positioning strip 100 is arranged in an arc or ring shape. This allows for better contact with the bottom spherical surface 031 of the glass surface dish 003, resulting in a better positioning effect. Furthermore, the first inclined surface 110 or the second inclined surface 120 can be selected according to requirements to adapt to the positioning of glass surface dishes 003 of different sizes, making it flexible and widely applicable.

[0058] That is, when the positioning strip 100 is arranged in a ring or an arc, the first inclined surface 110 and the second inclined surface 120 can each independently form two conical surfaces with different apex angles. The positioning strip 100 can be adjusted so that the first inclined surface 110 faces upwards, and the glass surface dish 003 is positioned by contacting the first inclined surface 110. Alternatively, the second inclined surface 120 can face upwards, and the corresponding first inclined surface 110 can face downwards, and the glass surface dish 003 is positioned by contacting the second inclined surface 120. This method is flexible and convenient to use.

[0059] In this embodiment, optionally, the positioning strip 100 and the elastic strip 200 are fixedly connected by adhesive.

[0060] It should be understood that the connection between the two is simple and reliable.

[0061] In this embodiment, optionally, the positioning strip 100 has a first side and a second side in its width direction, and the elastic strip 200 is located between the first side and the second side. The elastic strip 200 is blocked by the positioning strip 100, so the glass surface dish 003 is not easily in direct contact with the elastic strip 200.

[0062] For example, the elastic strip 200 can be located at the middle of the positioning strip 100 in its width direction, and the positioning strip 100 has a good blocking effect on the elastic strip 200.

[0063] In this embodiment, optionally, both the first and second sides are provided with outwardly folded edges 130. The positioning strip 100 can better cover the elastic strip 200 through the folded edges 130.

[0064] The positioning mechanism 001 provided in this embodiment can position the glass surface dish 003 on the lamp surface 021 of the lighting lamp 002. The positioning effect of the glass surface dish 003 is good, it is not easy to shift during operation, and it is safe and reliable.

[0065] This embodiment also provides a pancreatic tissue locator, including an illumination lamp 002 and a positioning mechanism 001 as described in the above embodiment; the positioning mechanism 001 is placed on the illumination lamp 002, and the positioning strip 100 of the positioning mechanism 001 is used to position the glass surface dish 003.

[0066] With this design, the positioning mechanism 001 is first placed on the lamp surface 021, and the tension strip 200 is adjusted to match the diameter of the lamp surface 021. After the tension strip 200 is adjusted, the structural shape of the positioning strip 100 is fixed. The glass dish 003 is then placed on the positioning strip 100, and the position of the glass dish 003 relative to the lighting lamp 002 is stable and reliable.

[0067] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
