Abstract
The invention aims to provide a fixing plate for mucosa resection tissue specimens under an endoscope, which does not damage the integrality of the resection tissue specimens and mainly comprises a fixing plate body for spreading the tissue specimens and a plurality of fixing stator blocks for pressing the tissue specimens on the fixing plate body.
Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a submucosal resection tissue specimen fixing plate under an endoscope.
Background
Endoscopic Submucosal Dissection (ESD) is a new treatment means appearing in recent years, is a technology with good clinical application prospect, enables more early digestive tract cancers to be completely resected under an endoscope at one time, and avoids the pain of an open surgery and the resection of organs. Compared with the endoscope treatment methods such as laparotomy and EMR in the past, the ESD has the advantages that 1, the wound is small, 2, a patient can receive multiple treatments at multiple positions, 3, a doctor can obtain a complete histopathology specimen for analysis, and 4, the resection rate of tumors with large areas, irregular shapes or combined ulcers and scars is higher than 96%, so that the recurrence probability is reduced.
At present, clinically, a cut specimen is generally spread on a fixing plate after an ESD operation and then fixed by using a pin, however, the pin may damage the tissue specimen, especially damage the edge, thereby affecting the analysis and diagnosis of the tissue specimen and the judgment of the tumor margin.
Disclosure of Invention
The invention aims to provide a fixing plate for a mucosa resection tissue specimen under an endoscope, which can not damage the integrity of the resection tissue specimen.
The invention is realized by the following technical scheme:
a tissue specimen fixing plate for endoscopic mucosal resection comprises a fixing plate body for spreading a tissue specimen and a plurality of fixing blocks for pressing the tissue specimen on the fixing plate body.
Further, the fixing plate body comprises a magnet I, and a plastic layer is wrapped outside the magnet I; the stator block comprises a magnet II, and a plastic layer is wrapped outside the magnet II.
Furthermore, the fixed plate body is square, the fixed stator block is circular or annular, and a plurality of burrs are arranged on the inner side surface of the fixed stator block.
Furthermore, any two adjacent side edges of the fixed plate body are provided with graduated scales.
Further, the fixed plate body has a specification of 5 × 5cm, 6 × 6cm, 10 × 10cm or 13 × 13 cm.
Further, the number of the fixed stator blocks is 12, the fixed stator blocks are distributed annularly, and the outer side surfaces of the fixed stator blocks are sequentially marked with numbers 1, 2 and 3 … … 12 in a counterclockwise direction.
Further, the external mounting of fixed plate body has the dustcoat of protection physiology sample, be equipped with a plurality of liquid hole on dustcoat (6), the colour of fixed plate body is light green or white.
Compared with the prior art, the invention has the following beneficial effects:
1. the tissue specimen is fixed and pressed on the fixing plate body through the magnetic attraction effect between the fixing stator block and the fixing plate body, and the integrity of the tissue specimen is prevented from being damaged through the pins;
2. the size of the specimen is estimated roughly through the graduated scale, so that the specimen is convenient to slice;
3. the invention has simple structure and convenient operation.

FIG. 1 is a schematic structural view of an endoscopic mucosal resection tissue specimen fixing plate according to the present invention;
FIG. 2 is a schematic view of the internal structure of FIG. 1;
in the figure: 1. the fixing plate body, 11, magnet I, 2, the stator piece, 21, magnet II, 3, burr, 4, scale, 5, tissue specimen, 6, dustcoat.
Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
An endoscopic mucosal resection tissue specimen fixation plate as shown in fig. 1-2 comprises a fixation plate body 1 for spreading a tissue specimen and twelve fixation blocks 2 for pressing the tissue specimen against the fixation plate body 1. Wherein, the specification of fixed plate body 1 is 10 × 10 cm's square, and fixed plate body 1 is inside to be magnet I11, then has the light green plastic layer of 1mm thickness in the outside plastic blasting of magnet I11. Every solid stator piece 2's appearance is the cylindrical of 6mm diameter height 8mm, and its inside is magnet II 21, then wraps the plastic blasting in the outside of magnet II 21 and has the light green plastic layer of one deck 1mm, and the medial surface of solid stator piece 2 is equipped with a plurality of burr 3, can be with firm the pressing of tissue sample on the fixed plate body like this. All fixed stator segments 2 are distributed annularly on the fixed plate 1, and the outer side surfaces thereof are sequentially marked with numerals 1, 2, 3 … … 12 in the counterclockwise direction. Therefore, the body part corresponding to each point position can be conveniently judged by a doctor according to the fixing of the clock point position, for example, a certain point represents the mouth side, the anus side, the inner side, the outer side and the like.
In order to initially observe the size of the tissue specimen, graduated scales 4 can be arranged on any two adjacent sides of the fixed plate body 1. In order to prevent the physiological specimen from being damaged by accidental collision before being placed in the formalin solution, the outer cover 6 for protecting the physiological specimen is arranged outside the fixing plate body 1, and the outer cover 6 is provided with a plurality of liquid permeating holes, so that the physiological specimen can be integrally placed in the formalin solution, and the physiological specimen is immersed in the formalin solution from the liquid permeating holes.
The specific working process of the endoscopic mucosal resection tissue specimen fixing plate is as follows:
the last exhibition of tissue specimen 5 that comes down of cutting is on the fixed plate body, then presses the stator piece on tissue specimen 5, because magnet I and magnet II's magnetism inhale the effect, can be with tissue specimen 5 tight fixed, has guaranteed tissue specimen 5's integrality simultaneously greatly.
