Description

Technical Field

[0001] The utility model relates to the technical field of clinical medicine, in particular to an esophagus simulation model specimen. Background Art

[0002] The esophagus is one of the important digestive tract tissues in the human body and plays a key role in the digestive process. Pathological changes in the esophageal mucosa are closely related to a variety of diseases such as esophageal cancer and esophagitis. Therefore, the observation and measurement of esophageal mucosal specimens are of great significance in clinical diagnosis and medical research.

[0003] At present, doctors and researchers mainly obtain esophageal mucosal image information through imaging methods such as CT and endoscopy, or directly observe the mucosal condition under the endoscope for judgment. However, these methods have certain limitations, and it is difficult to accurately evaluate important parameters such as the specific position, length, circumferential length and circumferential proportion of the specimen in the esophagus, thus affecting the comprehensive understanding and research of related diseases.

[0004] On the other hand, the existing technology also lacks a model that can truly simulate the internal environment of the esophagus, making it difficult to fix the esophageal mucosal specimen to its inner wall for observation and measurement. Due to the special anatomical structure of the esophagus, it is difficult to restore the real environment inside the esophagus by relying solely on a plane model, which makes it impossible to accurately measure and evaluate parameters such as the specimen's position, length, circumferential length, and proportion.

[0005] Therefore, there is an urgent need for a model that can intuitively simulate the internal structure of the esophagus so that parameters such as the position, length, circumferential length and circumferential proportion of the esophageal mucosal specimen fixed on its inner wall can be accurately measured, providing important support for the diagnosis and research of related diseases. Utility Model Content

[0006] In order to solve the problems of the prior art, the embodiment of the utility model provides an esophageal simulation model specimen. The technical solution is as follows:

[0007] On the one hand, an esophageal simulation model specimen is provided, comprising:

[0008] A hollow cylinder simulating the shape and size of a normal human esophagus;

[0009] A tearable soft layer wraps around the outer surface of the hollow column;

[0010] The cut esophageal mucosa specimen is fixed on the inner cavity wall of the hollow cylindrical body to measure the length, circumferential length and circumferential proportion of the esophageal mucosa specimen on the inner cavity wall;

[0011] A measuring ruler extends along the axial direction and the circumferential direction of the hollow cylindrical body and is used to measure the length and the circumferential length of the esophageal mucosal specimen fixed to the inner cavity wall.

[0012] Furthermore, the soft layer surrounding the outer surface of the hollow column is made of foam material or fabric.

[0013] Furthermore, it also includes a needle-shaped fixing part for fixing the esophageal mucosal specimen to the inner cavity wall of the hollow columnar body.

[0014] Furthermore, the needle-shaped fixing piece is a pin.

[0015] Furthermore, the hollow column is made of a hard paper tube or a plastic tube.

[0016] The beneficial effects brought by the technical solution provided by the embodiment of the utility model are:

[0017] 1. Real simulation of the internal environment of the esophagus

[0018] The shape and size of the hollow columnar structure of the model of the utility model correspond to the actual size of the normal human esophagus, and can truly restore the internal spatial structure of the esophagus. This provides a simulation environment that is highly close to the actual situation for fixing and observing esophageal mucosal specimens.

[0019] 2. Easy to fix and manipulate specimens

[0020] The outer surface of the hollow cylindrical structure of the model is wrapped with a tearable soft layer, so that the inner wall can be exposed, making it easy to fix the specimen on it. It is also equipped with a needle-shaped fixture that can firmly fix the specimen in the desired position, facilitating subsequent observation and measurement operations.

[0021] 3. Accurately measure specimen position and size

[0022] The model is equipped with measuring scales along the axial and circumferential directions, which can directly measure the length, circumferential length, and circumferential ratio of the specimen fixed to the inner cavity wall. Since the size of the model corresponds to the actual esophagus, the measurement results can truly reflect the situation of the specimen in the human esophagus, providing accurate data support for the diagnosis and research of related diseases.

[0023] 4. Easy to operate and low cost

[0024] The model has a simple structure and is made of common materials such as a hollow columnar structure, a soft layer, a needle-shaped fixing and a measuring ruler. It is easy to operate, has a low production cost, and has good practical value and prospects for promotion and application.

[0025] 5. Intuitive display, easy to observe

[0026] The model can intuitively present the internal structure of the esophagus. The observer can clearly observe the distribution position, shape and size of the specimen in the esophagus without the aid of imaging methods, which greatly facilitates clinical diagnosis and scientific research.

[0027] In summary, the esophageal simulation model specimen provided by the utility model can truly simulate the internal environment of the esophagus, facilitate the fixation and operation of the specimen, and provide support for the accurate measurement of parameters such as specimen position, length, circumferential length and proportion. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings required for use in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0029] Figure 1 It is a schematic diagram of an esophagus simulation model specimen according to an embodiment of the utility model. DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] The utility model provides an esophageal simulation model specimen, which is used to simulate the internal structure of the human esophagus and facilitate the fixation, observation and measurement of esophageal mucosal specimens. The model can truly reproduce the internal environment of the esophagus, so that the position, length, circumferential length and circumferential proportion of the specimen fixed on its inner cavity wall can be accurately measured, thereby providing support for the diagnosis and research of related diseases.

[0032] See also Figure 1 The esophagus simulation model specimen includes a hollow columnar structure 1 and a tearable soft layer 11.

[0033] The shape and size of the hollow columnar structure 1 correspond to the actual size of a normal human esophagus. Specifically, the hollow columnar structure 1 is cylindrical, and its length ranges from 20 to 30 cm, and its outer diameter ranges from 1.5 to 2.5 cm. By designing in accordance with the actual size of the esophagus, the internal spatial structure of the esophagus can be truly restored, providing a suitable simulation environment for specimen fixation and measurement.

[0034] The outer surface of the hollow columnar structure 1 is surrounded by a tearable soft layer 11. The soft layer 11 can be made of foam material or fabric. The soft layer 11 allows the inner cavity of the hollow columnar structure 1 to be exposed, thereby facilitating the fixing of the esophageal mucosal specimen on the inner cavity wall and measuring.

[0035] Specifically, the cut esophageal mucosa specimen can be fixed on the inner cavity wall of the hollow cylindrical structure 1 to measure the length, circumferential length and circumferential proportion of the esophageal mucosa specimen on the inner cavity wall.

[0036] To achieve the above measurement, the model also includes a measuring scale 12, which extends along the axial and circumferential directions of the hollow cylindrical structure 1. Specifically, circumferential and axial scale lines can be pre-set on the inner wall surface of the hollow cylindrical structure 1 as the measuring scale 12. By observing and measuring the starting and ending positions of the specimen fixed to the inner cavity wall on the measuring scale 12, the length (axial dimension) and circumferential length (circumferential dimension) of the specimen can be obtained. The circumferential length is divided by the entire inner circumference of the hollow cylindrical structure 1 to calculate the proportion of the circumference occupied by the specimen.

[0037] Specifically, the model may further include a needle-shaped fixing member 2 for fixing the esophageal mucosal specimen to the inner wall of the hollow cylindrical structure 1. The needle-shaped fixing member 2 is preferably a pin, which is convenient for firmly fixing the specimen at a desired position.

[0038] Specifically, the hollow columnar structure 1 can be made of common materials such as hard paper tubes or plastic tubes, which is conducive to the manufacture of the model.

[0039] When in use, first tear off the soft layer 11 on the outer surface of the hollow cylindrical structure 1 to expose the inner cavity wall. Then fix the esophageal mucosal specimen to be observed on the inner cavity wall of the hollow cylindrical structure 1, and use the needle-shaped fixing part 2 to fix the specimen at a specific position. After fixation, by observing the position and size of the specimen on the measuring scale 12, the length, circumferential length and circumferential proportion of the specimen can be measured. Since the size of the model corresponds to the actual esophagus, the measurement result can truly reflect the situation of the specimen in the human esophagus.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
