Embodiment 1

[0045] The invention provides a method for preparing a sucker, which comprises the following steps in sequence:

[0046] S1: First put the silica gel raw material and vulcanizing agent into the mixer and stir. At this time, the temperature of the mixer is 25°C, stir for 5 minutes, and then heat up at a heating rate of 2°C / min, and add acrylic acid to it in turn during the heating process Butyl ester, fluorine wax, silicone oil and mold release agent, when the temperature rises to 35°C, stop heating and stirring for 10 minutes, and finally add alumina, raise the temperature to 40°C, stir for 30 minutes, then cool down to 20°C at a cooling rate of 5°C / min , stand still for 1-2h to obtain the mixed material;

[0047] S2: Put the mixed material obtained in the above steps into a kneader, and perform closed-cover kneading and kneading at a temperature of 40-50°C;

[0048] S3: After the above steps are completed, raise the temperature to 60-70°C, add white carbon black therein, and...

Abstract

The invention discloses a soft tissue tumor specimen incision fixator and a preparation method of a sucker thereof. The soft tissue tumor specimen incision fixator comprises a storage box, wherein anopening is formed in one end of the storage box, a grid tray with the adjustable height is arranged in the storage box, a groove is formed in the inner wall of the storage box, a connecting rod is vertically arranged in the groove, a connector is arranged at the position, which is located in the groove, of the grid tray, a round hole is formed in the middle of the connector, the surface of the connecting rod is sleeved with the connector through the round hole, and a fastening ring is arranged at the joint of the connector and the connecting rod; and a stand column is arranged on the upper surface of the storage box, an adjusting rod rotationally connected with the stand column is arranged on the surface of the stand column, and a sucker is arranged at one end of the adjusting rod. The preparation method of the sucker comprises the steps of mixing, kneading, open milling, primary vulcanization and secondary vulcanization. The soft tissue tumor specimen incision fixator is provided withthe liftable grid tray, and the sucker can be adjusted under the action of the adjusting rod, so that the fixator can be suitable for soft tissue tumor specimens with different sizes and is convenient to use.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a soft tissue tumor specimen incision fixer and a preparation method of the sucker. Background technique [0002] Pathological specimens of soft tissue tumors after surgery should be fixed with 10% formalin in a timely manner. For soft tissue tumors with a diameter ≥ 2 cm, incisions should be made every 1 cm to allow formalin to penetrate into the tumor tissue to achieve full fixation. In clinical work, soft tissue tumor specimens are often elliptical, which can lead to difficulties in clamping and incision of specimens after surgery. The efficiency of postoperative specimen handling is low, and the thickness of specimens is uneven when incision, resulting in failure of tissue fixation. Inadequate fixation can lead to difficulties in obtaining materials and obtaining high-quality HE slices, causing errors in immunohistochemistry and molecular pathology results...
