Abstract
The utility model relates to a malignant tumor lymphatic channel transfer demonstrating model, which can be used for demonstrating the vivid and visual tumor lymphatic channel diffusion process for students. The malignant tumor lymphatic channel transfer demonstrating model has the technical scheme that a device comprises a simulated tumor lymphatic channel demonstrating model formed by a primary cancer model, a lymphatic model, a lymph gland model, a thoracic duct model and a blood pool, the lymphatic model is upwards communicated with the primary cancer model and is downwards communicated with the lymph gland model, the lymph gland model is communicated with the thoracic duct model and finally enters the blood pool, the lymph gland is a spiral tube, and the spiral tube walks from the outside to the inside. The lower ends of the primary cancer model and the lymph gland model are respectively provided with a regulating switch. The malignant tumor lymphatic channel transfer demonstrating model has the advantages that the structure is simple, and the development process of the tumor lymphatic channel transfer can be intuitively displayed, so medical students can have deep impressions on each link of the tumor lymphatic channel transfer.
Description
Technical field
The utility model relates to a kind of medical teaching and uses teaching aid, particularly malignant tumour lymphatic metastasis demonstrating model.
Background technology
In the pathology teaching, malignant cell is invaded lymphatic vessel and arrives regional nodes's formation lymphatic metastasis cancer from former position, get into blood flow secondary blood road at last and shift.The teacher says that time service is not dark with simple language description indigestion base content and impression.It is not only time-consuming on blackboard, to draw, and is difficult to the complete demonstration of true pathology is come out.Although multimedia teaching is vivid, ocular demonstration property technical ability is obviously not enough.
Summary of the invention
The utility model content:
The utility model can show exist not intuitively the lymphatic metastasis of prior art malignant tumour, not vivid, its each link of student's indigestion and provide a kind of simple in structure, visual pattern to show the pathologic process that the tumor lympha road shifts.
For achieving the above object, the utility model adopts following technical scheme:
Malignant tumour lymphatic metastasis demonstrating model; Comprise that the simulation tumor lympha road that primary carcinoma model, lymphatic vessel model, lymph node model, ductus thoracicus model and blood pool are formed shifts demonstrating model; Said lymphatic vessel model is upwards connected the primary carcinoma model; Connect the lymph node model downwards, lymph node model and ductus thoracicus model are connected, and get into blood pool at last; Said lymph is become spiral pipe, the traveling of spiral pipe ecto-entad.Said lymph node model comprises regional nodes's model and distant place lymph node model, and said primary carcinoma and lymph node lower end are provided with by-pass cock respectively.
The utility model according to technique scheme obtains is simple in structure, the strong and realization easily of ocular demonstration property.The utility model can intuitively demonstrate the evolution that the tumor lympha road shifts, and------------next stop lymph node---ductus thoracicus---gets into blood flow to the gathered edges hole to involve whole lymph node to invade lymphatic vessel to make the student stay deep impression to each link that the tumor lympha road shifts: cancer cell.

Embodiment:
For the technological means that the utility model is realized, creation characteristic is reached purpose and effect and is understood understanding easily, below in conjunction with the concrete further proof the utility model of demonstrating.
The malignant tumour of growing with the aggressive mode not only can be former position continued growth, spread, and can also be diffused into other positions of health through number of ways---shift.In case shift, the possibility of being cured reduces greatly.The mode that epithelial malignancy---cancer at first shifts is lymphatic metastasis; Cancer cell is invaded lymphatic vessel; Arrive regional nodes with lymph liquid; Be gathered in marginal sinus earlier and involve whole lymph node then and can continue to shift next stop lymph node, after ductus thoracicus gets into blood and the transfer of secondary blood road.
Based on above-mentioned principle; The utility model provides demonstrating model as shown in the figure; Explain as follows in conjunction with embodiment: the described malignant tumour lymphatic metastasis of the utility model demonstrating model; Comprise that the simulation tumor lympha road that primary carcinoma model 1, lymphatic vessel model 2, regional nodes's model 5, distant place lymph node model 10, ductus thoracicus model 12 and blood pool 14 are formed shifts demonstrating model, said lymphatic vessel model 2 is upwards connected primary carcinoma model 1, downwards through afferent lymphatic model 4 and 5 connections of regional nodes's model; Through efferent lymphatic vessel model 8 and lymph node model 10 connections at a distance, ductus thoracicus model 12 gets into blood pool 14; In said regional nodes 5 and the distant place lymph node model 10 is spiral pipe model 13, the 13 ecto-entad travelings of spiral pipe model.Said primary carcinoma model 1, regional nodes's model 5 and at a distance lymph node model 10 lower ends by-pass cock 3,9,11 is set respectively.
Be set to spiral pipe 13 shapes and ecto-entad traveling in said regional nodes model 5 and the distant place lymph node model 10; At first invade lymph node marginal sinus 6 with the simulation cancer cell; Then involve lymph node central area 7, communicate with ductus thoracicus model 12 at last, get into blood pool 14 and the transfer of secondary blood road.Through above design the student is more clearly observed and the forming process of understanding the lymphatic metastasis cancer.
According to the demonstrating model of technique scheme, concrete presentation process is following:
During use, at first close primary carcinoma model and regional nodes's model by-pass cock 9, cancer cell liquid is poured in the primary carcinoma model 1; Slowly open its by-pass cock, primary carcinoma cell liquid 15 flows into lymphatic vessel model 2 along with lymph liquid is descending, gets into regional nodes's marginal sinus 6 along afferent lymphatic model 4; Ecto-entad flows into lymph node central area 7 then; After the Where topical lymphatic metastasis, cancer cell continues to invade the next stop and distant place lymph node 10 through efferent lymphatic vessel 8, opens lymph node by-pass cock 11 at a distance; Cancer cell gets into ductus thoracicus 12, gets into blood pool 14 at last and the transfer of secondary blood road.
More than simulated the process of malignant cell lymphatic metastasis.
