Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a multifunctional auxiliary device for a pathological slicer. Background Technology

[0002] Pathological tissue sections have been widely used with the development of microscopy and immunoassay techniques, including frozen sections, paraffin sections, carbon-wax sections, ultrathin sections, and plastic sections. Among these, paraffin sections are the most commonly used. Paraffin sections are not only used to observe the morphology and structure of normal cells and tissues, but are also a primary method in pathology and forensic medicine for studying, observing, and judging morphological changes in cells and tissues. They are also widely used in research in many other disciplines. Paraffin sections preserve tissue structures well and have significant practical value in pathological and retrospective studies. They can cut continuous thin sections with clear tissue structures and accurate antigen localization. The microtome commonly used for paraffin sections is a rotary type, with thickness adjusters marked 0–50 μm or 0–25 μm, allowing for arbitrary thickness selection. The embedded paraffin blocks are trimmed into regular truncated pyramids with a blade. The thickness of paraffin sections is generally 2–7 μm, with a wide range of applications, does not affect antibody penetration, and produces uniform staining.

[0003] The preparation of paraffin sections typically involves embedding diseased tissue of varying sizes within paraffin blocks and then slicing them into 2-3 micrometer-thin sections using a microtome. The general procedure involves fixing the paraffin block in the clamp on the microtome head, adjusting the blade to a position close enough to cut the section, then adjusting the tissue section surface to precisely contact the blade, tightening the blade, securing the microtome head, and adjusting the section thickness as needed before cutting. In practice, when dealing with biopsy specimens containing tissue no more than 0.1 cm in diameter, achieving a precise cutting distance is difficult, leading to tissue loss during paraffin section preparation and affecting pathological diagnosis. Loss of small malignant pathological specimens can potentially result in medical disputes. Currently, the determination and adjustment of the cutting distance for paraffin sectioning relies primarily on visual observation, which introduces significant errors during operation, resulting in unnecessary loss of valuable tissue.

[0004] According to the novelty search report, CN216229804U discloses an auxiliary device for a pathological slicer, comprising: a base detachably mounted on the slicer housing support frame, one end of which is fixedly connected to the base, and the other end of which is rotatably connected to one end of the rotating frame; a semi-ring bracket connected in the middle to the other end of the rotating frame; a convex lens having a radial axis; one end of a first internally threaded tube rotatably connected to the middle of the support frame; one end of a second internally threaded tube rotatably connected to the middle of the rotating frame; and a threaded rod comprising a first threaded rod and a second threaded rod coaxially connected, the thread direction of the first threaded rod being opposite to the thread direction of the second threaded rod; the first threaded rod being threadedly connected to the other end of the first internally threaded tube; and the second threaded rod being threadedly connected to the other end of the second internally threaded tube.

[0005] The aforementioned technology discloses an auxiliary device for a pathological microtome. This device uses a tiltable, adjustable support mounted on the top of the microtome housing, consisting of a base, internally threaded tube, threaded rod, support frame, and rotating bracket. This support supports a convex lens, which magnifies the influence of the slide and blade position, allowing the operator to more promptly identify when the blade's cutting angle needs adjustment. This timely adjustment prevents the cutting of tissue specimens from being damaged, ensuring the accuracy of pathological diagnosis. However, the following problems exist during use:

[0006] 1. The method of manually rotating the screw to change the tilt angle of the support for the convex lens requires multiple rotations, and the operating position is located on the upper inner side, making operation inconvenient. Furthermore, relying solely on tilting the support to change position makes it difficult to quickly and accurately adjust the position of the convex lens, resulting in unsatisfactory convenience, efficiency, and accuracy. 2. After auxiliary observation, the convex lens protrudes directly above the operator's workstation, posing a risk of accidental head collision and injury during operation of the microtome, thus compromising safety. Therefore, a multifunctional auxiliary device for a pathological microtome is proposed to address the aforementioned problems. Utility Model Content

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1

[0038] like Figures 1 to 4 As shown, this embodiment proposes a multifunctional pathological microtome auxiliary device, including an auxiliary device body installed on the top of the microtome housing 100. The auxiliary device body includes:

[0039] A convex lens 5 is positioned at the upper right of the slicer housing 100;

[0040] The U-shaped base 1 is fitted onto the top outer side of the slicer housing 100;

[0041] A threaded drive clamping assembly is mounted on the U-shaped base 1 and makes tight contact with the top front side of the slicer housing 100; the threaded drive clamping assembly is used to clamp and fix the U-shaped base 1 to the top of the slicer housing 100 by unilateral operation;

[0042] L-shaped support rod 3 is fixedly connected to the top of U-shaped base 1;

[0043] The lifting and horizontal drive dual-adjustment support assembly is installed on the L-shaped support rod 3;

[0044] The U-shaped bracket 4 is fixedly installed on the right end of the lifting and horizontal drive dual-adjustment support assembly by two screws. The lifting and horizontal drive dual-adjustment support assembly is used to allow personnel to easily and quickly raise and lower the U-shaped bracket 4 and adjust it left and right according to observation needs, so as to accurately adjust the position of the convex lens 5.

[0045] The rotating friction damping assembly consists of two sets installed between the outer side of the convex lens 5 and the inner side of the U-shaped bracket 4, and is used for rotating support of the convex lens 5 and positioning of the friction damping after rotation adjustment.

[0046] It should be noted that the convex lens 5 is used to magnify the image of the slice 101 and the cutter 102 when they are facing the microtome housing 100, so that the operator can more promptly detect when the cutting angle of the cutter 102 needs to be adjusted, thereby adjusting the cutting angle of the cutter 102 in time, avoiding cutting off the tissue specimen, and ensuring the accuracy of pathological diagnosis.

[0047] Furthermore, such as Figure 3-4As shown, the threaded drive clamping assembly includes a U-shaped clamp 2 disposed in a U-shaped base 1. Both ends of the front side of the U-shaped clamp 2 slide out to the front side of the U-shaped base 1. A screw 202 is rotatably mounted on the rear inner wall of the U-shaped clamp 2. A threaded hole for threaded connection with the screw 202 is opened on the front inner wall of the U-shaped base 1. A knob 201 is fixedly connected to the front end of the screw 202. Three anti-slip rubber blocks 203 are glued and fixed on the rear side of the U-shaped clamp 2 and the rear inner wall of the U-shaped base 1. The two anti-slip rubber blocks 203 facing each other are squeezed and contacted with the front top and rear top of the slicer housing 100, respectively.

[0048] It should be noted that: a first bearing is fixedly connected to the inner rear wall of the U-shaped clamp 2, and the inner ring of the first bearing is fixedly connected to the outer side of the screw 202, which is used to support the rotation of the screw 202 and realize its rotational connection with the U-shaped clamp 2; and two rectangular guide holes are opened on the inner front wall of the U-shaped base 1, which are both in sliding contact with the outer side of the U-shaped clamp 2, so as to allow the U-shaped clamp 2 to pass through and guide its lateral sliding.

[0049] In this embodiment, the U-shaped base 1 is secured to the top outer side of the slicer housing 100 by the cooperation of the U-shaped clamp 2, screw 202, knob 201, and anti-slip rubber blocks 203. Then, the knob 201 is rotated directly from the front. The knob 201 drives the screw 202 to rotate and move backward in the threaded hole. The screw 202 drives the U-shaped clamp 2 to slide backward in the U-shaped base 1. The U-shaped clamp 2 drives the three anti-slip rubber blocks 203 on the front to press backward against the slicer housing 100. With the support and clamping of the three anti-slip rubber blocks 203 on the rear, the U-shaped base 1 is clamped and fixed to the top of the slicer housing 100 by convenient single-sided operation, providing a non-destructive and convenient connection basis.

[0050] Furthermore, such as Figure 1-4 As shown, the lifting and horizontal drive dual-adjustment support assembly includes a lifting plate 301 slidably sleeved on an L-shaped support rod 3. Two T-shaped guide rods 303 are fixedly connected to the top of the lifting plate 301. The L-shaped support rod 3 is slidably sleeved on the two T-shaped guide rods 303. A first electric telescopic rod 302 with its protruding end fixedly connected to the top of the lifting plate 301 is embedded and fixedly installed on the inner wall of the top of the L-shaped support rod 3. A rectangular tube 305 with a sealing structure at the right end is slidably sleeved on the lifting plate 301. A limit hole is opened on the inner wall of the bottom of the rectangular tube 305. A limit block that is slidably connected to the limit hole is fixedly connected to the bottom of the lifting plate 301, which has the effect of limiting and preventing the rectangular tube 305 from falling off. A second electric telescopic rod 304 with its protruding end fixedly installed to the top of the rectangular tube 305 is fixedly installed on the top of the lifting plate 301. A U-shaped bracket 4 is fixedly installed on the right end of the rectangular tube 305 by two screws.

[0051] It should be noted that: the top left side of the lifting plate 301 has a rectangular through hole that slides onto the outer side of the L-shaped support rod 3 for vertical sliding guidance of the lifting plate 301; and the top right side of the L-shaped support rod 3 has two vertical guide holes that slide onto the outer side of the corresponding T-shaped guide rod 303 for vertical sliding guidance of the T-shaped guide rod 303. With the vertical guidance on both sides of the first electric telescopic rod 302, the stable lifting displacement of the lifting plate 301 is ensured.

[0052] The left end and the right end of the extended end of the second electric telescopic rod 304 are fixedly installed on the top of the lifting plate 301 and the top of the rectangular tube 305 by corresponding mounting seats. The mounting seats are used to fix the second electric telescopic rod 304 to the top of the lifting plate 301 and to the top of the rectangular tube 305.

[0053] In this implementation scheme, the lifting plate 301, T-shaped guide rod 303, first electric telescopic rod 302, rectangular tube 305, and second electric telescopic rod 304 work together. The first electric telescopic rod 302 drives the lifting plate 301 to slide downward or move upward on the L-shaped support rod 3. The lifting plate 301 drives the two T-shaped guide rods 303 to slide vertically within the L-shaped support rod 3 for vertical guidance. The lifting plate 301 drives the rectangular tube 305 to move up and down for adjustment. The second electric telescopic rod 304 drives the rectangular tube 305 to slide horizontally left and right on the lifting plate 301 for horizontal adjustment. The vertical and horizontal movement of the rectangular tube 305 drives the U-shaped bracket 4 to move up, down, left, and right for adjustment. The electric drive allows personnel to conveniently and quickly raise, lower, and adjust the U-shaped bracket 4 to accurately adjust the position of the convex lens 5, improving the convenience, efficiency, and accuracy of adjustment.

[0054] Furthermore, such as Figure 3-4 As shown, the rotating friction damping assembly includes a rotating shaft 401. The two rotating shafts 401 are fixedly connected to the front and rear sides of the convex lens 5 respectively at their close ends. The two rotating shafts 401 are rotatably connected to the front and rear inner walls of the U-shaped bracket 4 respectively at their repulsive ends. A friction disc 402 is fixedly sleeved on the rotating shaft 401. Anti-slip damping rubber sleeves 403 in a squeezed and compressed state are bonded and fixed on the front and rear inner walls of the U-shaped bracket 4. The repulsive sides of the two friction discs 402 are squeezed and contacted with the close sides of the two anti-slip damping rubber sleeves 403 respectively. The rotating shaft 401 is located inside the corresponding anti-slip damping rubber sleeve 403 and does not contact its inner side.

[0055] It should be noted that: the inner walls of the front and rear sides of the U-shaped bracket 4 are fixedly connected with second bearings. The inner ring of the second bearing is fixedly fitted with the outer side of the corresponding rotating shaft 401, which serves to support the rotation of the rotating shaft 401 and realize its rotational connection with the U-shaped bracket 4.

[0056] In this embodiment, the rotating shaft 401, friction disc 402, and anti-slip damping sleeve 403 work together to provide rotational support for the convex lens 5 using two rotating shafts 401, providing the personnel with the conditions to rotate and adjust the convex lens 5. When the personnel rotate the convex lens 5, it drives the two friction discs 402 to rotate through the two rotating shafts 401. The friction discs 402 rub against the corresponding anti-slip damping sleeves 403. After adjustment, the squeezing friction force between the anti-slip damping sleeves 403 and the corresponding friction discs 402 achieves automatic friction damping positioning support for the rotating shaft 401, thereby achieving anti-rotation support for the convex lens 5 after rotational adjustment.

[0057] Furthermore, a battery is fixedly installed on the top rear side of the U-shaped base 1, and the first electric telescopic rod 302 and the second electric telescopic rod 304 are electrically connected to the battery through wires. A U-shaped handle is fixedly connected to the bottom left side of the L-shaped support rod 3.

[0058] It should be noted that the opening and closing of the first electric telescopic pole 302 and the second electric telescopic pole 304 are both controlled by conventional electric telescopic pole forward and reverse switches connected to the first electric telescopic pole 302 or the second electric telescopic pole 304 and the battery via wires. The connection of the first electric telescopic pole 302 and the second electric telescopic pole 304 to the corresponding forward and reverse switches for operation and control is a well-established and known method, and will not be described in detail here. The forward and reverse switches can be installed on the front right side of the U-shaped base 1, close to the operator's workstation, so that the operator can directly reach out and operate them.

[0059] This embodiment utilizes an electric drive with bidirectional adjustment for both upward and downward movement, as well as left and right movement, allowing personnel to conveniently and quickly raise and lower the convex lens 5 and adjust it left and right. This enables precise adjustment of the convex lens 5's position, improving ease of adjustment, efficiency, and accuracy. Furthermore, through another implementation method, the U-shaped bracket 4 and the convex lens 5 can be conveniently and quickly rotated to the upper left after use to avoid the upper part of the workstation, effectively preventing accidental head collisions and injuries to personnel operating the slicer housing 100 on the right side, thus improving safety.

[0060] The usage method of this embodiment is as follows: When using the multifunctional pathological slicer auxiliary device, after the U-shaped base 1 is clipped onto the outer top of the slicer housing 100, the knob 201 is directly rotated from the front. The knob 201 drives the screw 202 to rotate in the threaded hole and move backward. The screw 202 drives the U-shaped clamp 2 to slide backward in the U-shaped base 1. The U-shaped clamp 2 drives the three anti-slip rubber blocks 203 on the front to press against the slicer housing 100 backward. With the support and clamping of the three anti-slip rubber blocks 203 on the rear, the U-shaped base 1 is clamped and fixed on the top of the slicer housing 100 by convenient single-sided operation, providing a non-destructive and convenient connection basis.

[0061] The operator directly activates the first electric telescopic rod 302, which drives the lifting plate 301 to slide downwards or move upwards on the L-shaped support rod 3. The lifting plate 301 drives the two T-shaped guide rods 303 to slide vertically within the L-shaped support rod 3 for vertical guidance. The lifting plate 301 drives the rectangular tube 305 to move up and down for adjustment. The operator operates the second electric telescopic rod 304 to drive the rectangular tube 305 to slide horizontally left or right on the lifting plate 301 for horizontal adjustment. The rectangular tube 305 moves up, down, left, and right, which drives the U-shaped bracket 4 to move up, down, left, and right for adjustment. The U-shaped bracket 4 drives the convex lens 5 to move up, down, left, and right for adjustment. After the adjustment is appropriate, the operator can directly close the first electric telescopic rod 302 and the second electric telescopic rod 304. This allows for convenient and quick raising and lowering and left and right adjustment of the convex lens 5 using electric drive and bidirectional adjustment, so as to accurately adjust the position of the convex lens 5 and improve the convenience, efficiency and accuracy of adjustment.

[0062] Two rotating shafts 401 are used to support the rotation of the convex lens 5, providing the operator with the means to adjust the convex lens 5. When the operator rotates the convex lens 5, it drives the two friction discs 402 to rotate through the two rotating shafts 401. The friction discs 402 rub against the corresponding anti-slip damping sleeves 403. After the convex lens 5 is aligned with the slice 101 and the cutter 102, the force applied to it is stopped. At this time, the squeezing friction between the anti-slip damping sleeves 403 and the corresponding friction discs 402 achieves automatic friction damping positioning support for the rotating shafts 401, thereby supporting the convex lens 5 after rotation adjustment to prevent it from rotating on its own. When the convex lens 5 is facing the slice 101 and the cutter 102 of the microtome housing 100, it magnifies the image at this position, so that the operator can more promptly detect when the cutting angle of the cutter 102 needs to be adjusted, thereby adjusting the cutting angle of the cutter 102 in time, avoiding cutting off the tissue specimen, and ensuring the accuracy of pathological diagnosis.

[0063] Example 2

[0064] Reference Figure 5-6 As shown, this embodiment differs from Embodiment 1 in that the L-shaped support rod 3 can also be hinged to the top of the U-shaped base 1. The same inclined third electric telescopic rod 306 is hinged between the top right side of the U-shaped base 1 and the left inner wall of the L-shaped support rod 3. The third electric telescopic rod 306 is electrically connected to the battery through a flexible wire.

[0065] This embodiment allows for convenient and quick rotation of the U-shaped bracket 4 and convex lens 5 to the upper left after use to avoid the upper part of the workstation, effectively preventing accidental head collisions and injuries to personnel operating the slicer housing 100 on the right side, thus improving safety.

[0066] It should be noted that the hinge between the L-shaped support rod 3 and the U-shaped base 1 is achieved by using conventional supports and stainless steel shafts. Specifically, two supports are welded and fixed to the top of the U-shaped base 1, and the L-shaped support rod 3 has a hole at the bottom front side for installing bearings. A stainless steel shaft is fixed inside the inner ring of the bearings and fixed or welded to the inner side of the two supports. The stainless steel shaft is used to provide a stable hinge connection by utilizing the high strength and wear resistance of stainless steel.

[0067] The bottom and the extended end of the third electric telescopic pole 306 are both hinged to the U-shaped base 1 and the L-shaped support pole 3 via hinge seats.

[0068] It should be further explained that the opening and closing of the third electric telescopic pole 306 is controlled by a conventional electric telescopic pole forward and reverse switch connected to the battery via wires. The connection method of the third electric telescopic pole 306 for personnel operation and control via a corresponding forward and reverse switch is a well-established and known method, and will not be described in detail here. The forward and reverse switch can be installed directly on the front side of the third electric telescopic pole 306, as it is located close to the U-shaped base 1 and near the right-side personnel work area, allowing personnel to directly reach and operate it.

[0069] The usage method of this embodiment is as follows: The difference from Embodiment 1 is that, under the premise that the L-shaped support rod 3 and the U-shaped base 1 are hinged, it also has the following functions: After observation and use, the personnel can directly start the third electric telescopic rod 306 in the forward direction to drive the L-shaped support rod 3 to rotate to the left. The L-shaped support rod 3 drives the U-shaped bracket 4 and the convex lens 5 to rotate to the upper left through the lifting plate 301 and the rectangular tube 305 in sequence, so as to avoid the upper right position of the slicer housing 100. This achieves the effect of conveniently and quickly rotating the U-shaped bracket 4 and the convex lens 5 to the upper left after use to avoid the upper part of the workstation, effectively avoiding the phenomenon of accidental head collision and injury to the convex lens 5 when the personnel operate the slicer housing 100 on the right side, and improving the safety of use.

[0070] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
