Problems solved by technology

However, because most of the tissue samples are irregular, it is not easy to fix when cutting, and it is difficult to guarantee the thickness of different slices; in addition, multiple slices are stacked together, which is easy to confuse the order of arrangement, which will affect the follow-up observation and recording of the continuous and complete morphology of the conduction system. cause some trouble

Embodiment 1

[0126] Embodiment 1 A kind of cardiac conduction system histopathological sampling device

[0127] This embodiment provides a pathological sampling device for cardiac conduction system tissue, which is used to obtain sinoatrial node and atrioventricular node tissue of the cardiac conduction system, and obtain sinoatrial node tissue slices and atrioventricular node tissue slices with uniform thickness.

[0128] like Figure 6 As shown, a pathological sampling device for cardiac conduction system tissue, including positioning scissors and a slicing groove. Wherein, the positioning scissors include a first cutter body 1, a second cutter body 2 and a material-taking component, the first cutter body 1 includes a first handle 13 and a first cutting edge 14, and the second cutter body 2 includes a second handle 22 and a second handle 22. Two cutting edges 23, the first knife body 1 and the second knife body 2 are rotatably connected at the intersection of the handle and the cutting ...

Embodiment 2

[0186] Embodiment 2 A kind of cardiac conduction system histopathological sampling method

[0187] When collecting materials from the sinoatrial node of the cardiac conduction system, take the fixed heart, find the right atrial sulcus, and ensure that the superior vena cava and inferior vena cava have been opened along their long axis, and the structure of the sulcus and the right atrial appendage ridge is intact. Each chamber of the heart has been opened; then, insert the sinoatrial node positioning area insertion piece 31 into the positioning observation window slot 12, leave the first handle 314 outside, and hold the first handle 13 and the second handle 22 in the right hand, so that positioning and taking materials Keep the scissors open, spread the stumps of the superior vena cava and inferior vena cava with the left hand, so that the boundary groove, the ridge of the right atrial appendage, and the stumps of the superior vena cava are fully exposed, insert the scissors fo...

Abstract

The invention discloses a pathological sampler of a heart conduction system tissue and a sampling method for sampling a heart conduction system tissue. The invention firstly provides a pathological sampler of a heart conduction system tissue. The pathological sampler includes locating and sampling scissors and a slicing groove. A rectangular cutting area can be formed by an observation and sampling component of the invention. When a sinoatrial node and an atrioventricular node are cut, a locating area is defined by six easily identified structures to realize simple and accurate identification.The rectangular area formed by the locating and sampling scissors and a holding component are meshed with each other, and a target tissue block can be cut off successfully at one time. A locating observation window insertion groove is arranged on the locating and sampling scissors to flexibly install and replace two transparent insertion sheets so that location and sampling in the two areas can be realized. A tissue slice with a uniform thickness can be obtained by the slicing groove. In addition, the invention provides a method for sampling a heart conduction system tissue. The method is simple and safe, is able to obtain a high-quality tissue specimen slice, and is of great value in application and popularization.

Description

technical field [0001] The invention relates to the technical field of pathological slices, and more specifically, to a pathological sampling device for cardiac conduction system tissue and a sampling method thereof. Background technique [0002] The cardiac conduction system is composed of the sinoatrial node, atrioventricular node, atrioventricular bundle, left and right bundle branches and terminal fiber network, maintaining the normal rhythm of the heart. Conduction system lesions are the pathological basis of unstable electrocardiographic function, and arrhythmia can occur, leading to death. In forensic pathology work, the routine inspection of the cardiac conduction system is the inspection of the sinoatrial node and the atrioventricular node. However, in the autopsy work, forensic workers often do not pay enough attention to the examination of the cardiac conduction system. familiar. If the examination of the cardiac conduction system is neglected, it is easy to be...
