Frozen section immunohistochemical automatic stainer

Abstract

The invention discloses a frozen section immunohistochemical automatic stainer. The stainer comprises a controller, a motor, a probe, a pipeline, a first reagent bin, a second reagent bin, a third reagent bin, and a mechanical shaft; the controller is used for controlling the probe to move along the mechanical shaft; the controller is further used for controlling the motor to rotate, thereby feeding the liquid in the first reagent bin, the second reagent bin and the third reagent bin into the probe along the pipeline; and the probe is used for spraying the liquid to a to-be-stained tissue section. The timeliness and the stability of the staining technology can be well improved.

Description

technical field [0001] The invention relates to the field of frozen section staining, in particular to an automatic staining instrument for frozen section immunohistochemistry. Background technique [0002] In surgery, it is often difficult to judge whether the tumor is benign, malignant or borderline. Different types of tumors have different surgical scopes. If it is a malignant tumor, it is often necessary to expand the scope of surgical resection. However, frozen sections of surgical specimens Pathological diagnosis is difficult to obtain a definite diagnosis based on morphology. Immunohistochemical techniques are needed to assist in differential diagnosis, clarify specific tumor types, and allow surgeons to grasp the scope of surgery. However, the development of immunohistochemistry for frozen sections is still immature. The application of intraoperative frozen section immunohistochemical technology has not been completed, and the current stability, timeliness and relate...

Problems solved by technology

[0002] In surgery, it is often difficult to judge whether the tumor is benign, malignant or borderline. Different types of tumors have different surgical scopes. If it is a malignant tumor, it is often necessary to expand the scope of surgical resection. However, frozen sections of surgical specimens Pathological diagnosis is difficult to obtain a definite diagnosis based on morphology. Immunohistochemical techniques are needed to assist in differential diagnosis, clarify specific tumor types, and allow surgeons to grasp the scope of surgery. However, the development of immunohistochemistry for frozen sections is still immature. The application of intraoperative frozen section immunohistochemical technology has not been completed, and the current stability, timeliness and related antibodies are under development, which seriously restricts the development and application of this technology
