Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a preparation method of a soft tissue tumor specimen incision fixator and its suction cup. Background Art

[0002] After the pathological specimen of soft tissue tumor is removed, it needs to be fixed with 10% formalin in time. For soft tissue tumors with a diameter ≥ 2 cm, it is necessary to make incisions every 1 cm to allow formalin to penetrate into the tumor tissue for sufficient fixation. In clinical work, the soft tissue tumor specimen is often oval, which makes it difficult to clamp the specimen after surgery, difficult to incise the specimen, low efficiency in processing the postoperative specimen, uneven thickness when incising the specimen, resulting in tissue fixation failure. Without sufficient fixation, it can lead to difficult sampling, difficult to obtain high-quality HE sections, causing errors in immunohistochemistry and molecular pathology results, and incorrect pathological diagnosis can interfere with clinical treatment. Clinicians often hold the specimen with one hand and incise the specimen with the other hand, which is prone to blade cutting injuries and cause iatrogenic exposure. At the same time, it is not easy to measure the major axis and minor axis of the tumor after the oval tumor is removed. The base of the present invention has a 1*1 cm grid. After fixing the specimen with the specimen fixing suction cup, the major axis and minor axis of the tumor can be directly read, which is convenient and fast.

[0003] In Patent 201520950579.8, a fixing and cutting device for sectional specimens, which is provided with a plurality of liquid seepage holes on a rectangular chassis, fixing baffles are respectively fixed on two adjacent sides of the chassis, a slideway is arranged in the middle of each baffle, a plurality of vertical baffle knife grooves are arranged on each baffle, a vertical slide plate capable of moving along the slideway is arranged on each slideway, a slide plate fixing device is arranged on the vertical slide plate, a plurality of bars perpendicular to it are arranged on each vertical slide plate, and a plurality of bar knife grooves corresponding to the baffle knife grooves on the opposite baffle are arranged on each bar. A pull-out liquid collection drawer is arranged at the bottom of the chassis. The present invention can fasten the sectional specimen on the chassis, and the sectional specimen can be well and regularly cut by the cutting knives on the baffle knife grooves and bar knife grooves for easy observation, thus improving the teaching effect. Although the above problems are solved, there are still the following problems:

[0004] The fixing and cutting device for sectional specimens can only fix specimens of the same or different sizes. When the specimen is too large, it cannot be used and does not have an adjustment function, making it inconvenient to use.

[0005] In Patent CN201610213972.8, a silicone suction cup, its preparation method, and a pendant including the silicone suction cup; the silicone suction cup comprises the following components: 60 - 105 parts of methyl vinyl silicone rubber; 20 - 50 parts of silica; 1 - 8 parts of hydroxy silicone oil; 2 - 10 parts of dimethyl silicone oil; 0.1 - 0.4 parts of mold release agent; 0.5 - 1.5 parts of vulcanizing agent; the preparation method comprises the following steps: 1) weighing raw materials according to parts by weight; 2) kneading and mixing; 3) adding powder; 4) cold rolling; 5) cooling; 6) evacuating and cooling; 7) open rolling and filtering; 8) rubber mixing; 9) primary vulcanization; 10) secondary vulcanization; a pendant according to the present invention comprises a silicone suction cup, a connecting part, and a cap; the silicone suction cup has the physical property of silicone molecule migration and penetration, and has natural physical adsorption to ceramics, glass, etc.; the pendant is adsorbed on the wall surface in a planar negative pressure manner, and the structure of the pendant can be changed in a detachable manner, which is suitable for use in different occasions. However, there are still the following problems:

[0034] The following further describes the specific embodiments of the present invention with reference to the drawings. It should be noted here that the description of these embodiments is for helping to understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0036] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0037] The present invention provides a soft tissue tumor specimen incision fixator as shown in Figures 1-5 Figure 8, which includes a storage box 1. One end of the storage box 1 is open, and an adjustable-height grid tray 2 is arranged inside the storage box 1. A groove 3 is arranged on the inner wall of the storage box 1. A connecting rod 7 is vertically arranged inside the groove 3. The grid tray 2 is provided with a connecting head 8 at the position of the groove 3. A round hole 10 is arranged in the middle of the connecting head 8. The connecting head 8 is sleeved on the surface of the connecting rod 7 through the round hole 10 and is slidably arranged relative to the connecting rod 7. A fastening ring 9 is arranged at the connection between the connecting head 8 and the connecting rod 7;

[0038] Vertical columns 6 are arranged on the upper surface of the storage box 1. There are 4 vertical columns 6, which are respectively distributed in the middle of the four sides of the storage box 1. An adjusting rod 5 is rotatably connected to the surface of the vertical column 6. A suction cup 4 is arranged at one end of the adjusting rod 5.

[0039] Specifically, a handle 11 is arranged at the other end of the adjusting rod 5.

[0040] Specifically, the surface of the handle 11 is provided with grooves for increasing the friction force during rotation.

[0041] Specifically, the surface of the vertical column 6 is provided with a slot hole, and the inner wall of the slot hole is provided with internal threads.

[0042] Specifically, the surface of the adjusting rod 5 is provided with external threads for threaded connection with the internal threads.

[0043] During the use of the soft tissue tumor specimen incision fixator, first place the soft tissue tumor specimen to be incised on the grid tray 2. Then, according to the size of the soft tissue tumor specimen, press down or pull up the grid tray 2 to adjust the position of the soft tissue tumor specimen so that the suction cup 4 can accurately clamp its middle part. Since the fastening ring 9 is provided on the connecting head 8, the connection between the fastening ring 9 and the connecting rod 7 is tight, and it requires manual pushing to move the grid tray 2. The force during normal cutting will not cause the grid tray 2 to move. Then rotate the adjusting rods 5 in four directions. The notch on the handle 11 facilitates the application of force by hand, enabling the suction cup 4 to fix the soft tissue tumor specimen in the middle, facilitating cutting. The suction cup 4 is small, but has a good fixing effect, and the connection between the suction cup 4 and the adjusting rod 5 is also fixed by the suction cup, facilitating the replacement of suction cups 4 of different models and sizes. The distance between the grids of the grid tray 2 is set, and the long diameter and transverse diameter of the specimen can be directly read after the specimen is fixed, which is convenient for use.
