The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations. The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
As described in the technology of the application, no device capable of installing and fixing the lung organ for convenient experimental operation exists in the prior art. The inventor of the application finds that doctors need to do a large amount of exercise operation before being skilled in lung surgery, and the animal lungs can be simulated to be human lungs in reality, but the device for installing and fixing the lung organs is lacked, so that the lung organ simulation experiment is difficult to proceed.
In order to solve the above problems, the inventor of the present application proposes a technical solution of the present application, and specific embodiments are as follows:
example one

As shown in fig. 1, wherein the shelf body comprises: go up casing 1 and casing 11 down, go up the inside hollow structure of casing 1, the inside hollow structure that is of casing 11 down equally, go up casing 1 lid and establish back on casing 11 down, inside vacuole formation. The cross section of the upper shell 1 is in a kettle shape, and the cross section of the lower shell 11 is also in a kettle shape. Since the upper casing 1 is a kettle, the right end is larger and the left end is smaller, the left end of the upper casing 1 is defined as the front end of the upper casing 1, the right end of the upper casing 1 is defined as the rear end, and the lower casing 11 is similarly divided. An operation window 12 is arranged at the left end of the upper shell 1, the operation window 12 is used for externally connecting other components, and when other components need to be externally connected, the operation can be carried out only by extending the operation window 12 into the cavity. Other ablation components are externally connected for operation, and when the ablation tube enters the lung organ in the cavity through the operation window 12, the operation can be carried out in the lung organ.
As shown in fig. 3, the supporting mechanism is located inside the cavity, and the bottom of the supporting mechanism is fixed on the inner wall of the lower housing 11, and the supporting mechanism includes: a holding member 2 and a plurality of elastic components 21. Four elastic components 21 are arranged in the cavity, and the tail ends of the elastic components 21 are fixed on the inner wall of the right end of the frame body. Two elastic components 21 are fixed on the upper shell 1 and the lower shell 11, and the elastic components 21 on the upper shell 1 and the elastic components 21 on the lower shell 11 are parallel to each other, so that the cross section is rectangular. The supporting part 2 is divided into two parts, the upper half part of the supporting part 2 is sleeved on the elastic component 21 fixed on the upper shell 1, the lower half part of the supporting part 2 is sleeved on the elastic component 21 fixed on the lower shell 11, and when the upper shell 1 is buckled on the lower shell 11, the upper half part and the lower half part of the supporting part 2 are buckled to form a half-moon-shaped frame body. The left end of the holding member 2 is closed to form a top end, and a space for placing the lung organ is formed between the left end of the holding member 2 and the front end of the lower housing 11. Because the elastic component 21 has a telescopic function, when the elastic component 21 moves towards the right side, the elastic component 21 drives the abutting part 2 to move towards the right end, so that the space between the top end of the abutting part 2 and the front end of the lower shell 11 is increased, the lung organ is placed in the elastic component, after the lung organ is placed, the elastic component 21 is loosened, the elastic component 21 enables the elastic component to return to the initial state to move towards the left end due to elasticity, and therefore the abutting part 2 fixes the lung organ. The lung organ is placed on the supporting mechanism, and one side of the lung organ inlet is placed at the front end of the upper shell 1 for operation.

The left end of guide is fixed with bracing piece 211, and the other end of guide cup joints on the fixed column. Four first buckles 213 are arranged on the left end surface of the fixed column. If the supporting rod 211 needs to be moved to the right, the guiding element drives the supporting rod 211 to move to the right end, the guiding element extrudes the spring to enable the spring to be in a contraction state, at the moment, the distance between the left end of the guiding element and the left end of the fixing column is gradually shortened, and when the spring needs to be kept in a compression state, the fastening ends 224 of the first fasteners 213 arranged on the surface of the fixing column are fastened on the surface of the left end of the guiding element, so that the guiding element can be fixed. If it is necessary to return the support bar 211 to the original position, the hooking end 224 of the first hooking member 213 is simply removed from the surface of the guide member, and the support bar 211 is returned to the original position by the resilient force of the spring.
As shown in fig. 2, a gas delivery device is installed on the surface of the upper casing 1, and the gas delivery device is used to supply gas to the pulmonary organ so that the pulmonary organ can contract and expand like a lung in a human body.
