Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an intestinal tissue fixation device for pathological examination. Background Technology

[0002] In pathological examination, intestinal tissue needs to be fixed before it can be sectioned for observation. Traditional fixation methods are mostly done manually, using forceps or sutures. This is cumbersome and can easily damage the tissue. Some fixation devices have simple structures and are difficult to adapt to intestinal tissues of different sizes and shapes, resulting in poor fixation and affecting the accuracy of subsequent pathological analysis. Existing technical problems: 1. Traditional manual fixation methods are complex to operate, easily cause tissue damage, and uneven fixation force leads to tissue deformation, affecting the quality of pathological sections. 2. Existing fixation devices are difficult to adapt to intestinal tissues of different sizes, have poor versatility, and require device replacement for different samples, increasing operating costs and time. Therefore, it is necessary to design an intestinal tissue fixation device for pathological examination to solve the above problems. Summary of the Invention

[0017] Please see Figure 1-5 This utility model provides a technical solution: The intestinal tissue fixation device for pathological examination includes a base 1. The left and right front ends of the base 1 are each provided with a push-pull groove 2. A push-pull device 3 is slidably connected in the push-pull groove 2. Fastening devices 4 are slidably connected around the upper end of the push-pull device 3. There are four fastening devices 4.

[0018] In this embodiment, the push-pull device 3 includes a pull-out plate 31. A protrusion 32 is fixedly connected to the lower left and lower right ends of the pull-out plate 31. A handle 33 is fixedly connected to the upper front end of the pull-out plate 31. A first sliding groove 34 is opened at both the upper front and upper rear ends of the pull-out plate 31. A connecting component 35 is slidably connected within the first sliding groove 34. Two connecting components 35 are provided, and the two connecting components 35 are symmetrically distributed left and right. The pull-out plate 31 is slidably connected to the upper part of the base 1 via the protrusions 32. The connecting component 35 includes a connecting plate 351, and a second sliding groove is opened at the upper end of the connecting plate 351. The groove 352 has two displacement blocks 353 slidably installed inside the second sliding groove 352. The middle of the left end and the middle of the right end of the displacement block 353 are fixedly connected to the slider 354. The front and rear of the upper end of the displacement block 353 are both opened with guide holes 355. The middle of the upper end of the displacement block 353 is opened with a screw hole 356. The front and rear of the lower end of the connecting plate 351 are slidably connected in the first sliding groove 34. The push-pull groove 2 is opened along the left and right direction of the front end of the base 1, and the two push-pull grooves 2 are arranged parallel to each other. The position of the protrusion 32 slidably embedded in the push-pull groove 2 is adapted to the shape of the push-pull groove 2.

[0019] Through the above scheme: the pull-out plate 31 is slidably connected to the push-pull grooves 2 that are opened in the left and right directions and are parallel to each other at the front end of the base 1 via the protrusions 32 on the lower left and right sides. The shape of the protrusions 32 and the push-pull grooves 2 are adapted to each other, so that the pull-out plate 31 can be smoothly pulled out by the handle 33 at the upper front end, which is convenient for placing intestinal tissue. Two connecting components 35 are symmetrically distributed on the left and right sides and are slidably connected in the first sliding groove 34 at the front and rear of the upper end of the pull-out plate 31. The lower end of the connecting plate 351 of the connecting component 35 can slide in the first sliding groove 34 to adjust the left and right position. The upper end of the connecting plate 351 can slide in the first sliding groove 34 to adjust the left and right position. The displacement block 353, which is slidably installed in the second sliding groove 352 of its upper end, can be adjusted in the front and back position by the slider 354, so that the displacement block 353 can be adjusted in the pull-out plate 351. The device allows for two-dimensional position adjustment to accommodate intestinal tissues of different sizes. The screw hole 356 at the upper center of the displacement block 353 can be threaded to the adjusting screw 42 of the fastening device 4. By turning the screw block 41, the pressure block 44 is lowered, allowing the fixing conical needle 45 to pierce the tissue for fixation. At the same time, the guide rod 43 cooperates with the guide hole 355 to guide and ensure the stability of the fixation process. This solution achieves convenient pulling of the pull plate 31 through the sliding cooperation of the push-pull groove 2 and the protrusion 32. The setting of the first sliding groove 34 and the second sliding groove 352 allows the connecting component 35 and the displacement block 353 to be adjusted in multiple dimensions, thereby achieving flexible positioning and fastening of intestinal tissues of different sizes, improving the applicability and ease of operation of the fixation device.

[0020] In this embodiment, the fastening device 4 includes an adjusting screw 42. The upper end of the adjusting screw 42 is fixedly connected to a screw block 41, and the lower end of the adjusting screw 42 is movably connected to a pressure block 44 via a bearing. The bottom of the pressure block 44 is fixedly connected to a plurality of fixed conical pins 45. The front and rear parts of the lower end of the pressure block 44 are both fixedly connected to guide rods 43. The adjusting screw 42 is threaded into a screw hole 356. The position and size of the guide rod 43 correspond to the position and size of the guide hole 355. The plurality of fixed conical pins 45 are all conical in shape and are evenly distributed in a rectangular shape.

[0021] Through the above scheme: when the screw block 41 is turned, the adjusting screw 42 rotates within the screw hole 356 of the displacement block 353. Since the lower end of the adjusting screw 42 is movably connected to the pressure block 44 through a bearing, and the guide rod 43 at the lower end of the pressure block 44 slides into the guide hole 355 of the displacement block 353, the rotational motion of the adjusting screw 42 is converted into the linear lifting and lowering motion of the pressure block 44. As the pressure block 44 descends, multiple rectangularly evenly distributed conical fixed conical needles 45 at the bottom gradually pierce the intestinal tissue, achieving tissue fixation. The corresponding cooperation between the guide rod 43 and the guide hole 355 ensures the smooth lifting and lowering of the pressure block 44 and avoids the skewness of the fixed conical needles 45. This scheme achieves the lifting and lowering adjustment of the pressure block 44 through threaded transmission, and uses the guide structure to ensure the stability of the fixation process. The rectangularly evenly distributed conical fixed conical needles 45 can disperse pressure and effectively pierce the tissue, improving the reliability and uniformity of intestinal tissue fixation and providing a stable sample fixation effect for subsequent pathological examination.

[0022] It should be noted that this utility model is an intestinal tissue fixation device for pathological examination. When this device is in operation, the base 1 is first placed. Since the push-pull groove 2 is opened along the left and right directions of the front end of the base 1 and is parallel to each other, the protrusion 32 is slidably embedded in the push-pull groove 2 and its position and shape are adapted. By pulling the handle 33 at the upper front end of the pull plate 31, the protrusion 32 slides within the push-pull groove 2, allowing the pull plate 31 to be pulled out from the base 1. After placing the intestinal tissue on the pull plate 31, the left and right positions of the two connecting components 35 are adjusted according to the tissue size by sliding the lower end of the connecting plate 351 within the first sliding groove 34. Then, the displacement block 353 slides within the second sliding groove 352. Guided by slider 354, the front and rear positions of displacement block 353 are adjusted to place displacement block 353 in a suitable position. Then, the adjusting screw 42 of fastening device 4 is threaded into screw hole 356 of displacement block 353. Since the position dimension of guide rod 43 corresponds to guide hole 355, rotating screw block 41 drives adjusting screw 42 to rotate, causing pressure block 44 to move and descend at the lower end of adjusting screw 42 through bearing. Multiple fixed conical needles 45 with conical structure and uniform rectangular distribution gradually pierce intestinal tissue. At the same time, guide rod 43 slides in guide hole 355 to guide, realizing the fastening of intestinal tissue. Finally, pull plate 31 is slid back to base 1 through protrusion 32 to complete the fixation of intestinal tissue.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
