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
The invention relates to a lung propping and supporting device with the function of maintaining lung surface activity, which comprises: support body, supporting mechanism and heating device. 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. As shown in fig. 2, the cross section of the upper casing 1 is in the shape of a kettle, and the cross section of the lower casing 11 is also in the shape of a kettle. 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. The vertical cross section of the lower shell 11 is W-shaped, and the W-shaped is matched with the bottom of the abutting piece 2, so that the abutting piece 2 is fixed more stably. 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.
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, as shown in fig. 4, the supporting mechanism includes: a holding member 2 and a plurality of elastic members 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. Wherein, 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, thereby forming a rectangle section. 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.
As shown in fig. 3 and 4, the elastic member 21 includes: the support rod 211, the guide, the elastic member 212, the fixing column and a plurality of first buckles 213.

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 installed on the left end surface of the fixing column. If need move bracing piece 211 to the right, drive bracing piece 211 through the guide and move to the right end, guide extrusion spring makes the spring be in the shrink state, and the distance between the left end of guide and the left end of fixed column shortens gradually this moment, and when needs the spring to keep compression state, the lock joint end 224 lock joint that will install a plurality of first buckles 213 on fixed column surface can be fixed the guide at the guide left end surface. 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.
The lung support apparatus for maintaining pulmonary surfactant activity further comprises: as shown in fig. 3, the heating device is installed on the outer wall of the lower casing 11, and is located in the space between the front end of the abutting member 2 and the front end of the cavity, and is used for heating the lower casing 11, so that the lower casing 11 heats the lung organ contacted with the lower casing 11 after generating heat, thereby preventing the surface of the lung organ from being damaged due to overhigh temperature of the direct contact between the heating device and the surface of the lung organ, and maintaining the temperature of the lung organ and the activity of the lung organ.
From the above, it can be seen that the lung supporting apparatus with lung surfactant maintaining function of the present invention comprises: support body, supporting mechanism and heating device form the cavity between last casing 1 and lower casing 11, and supporting mechanism sets up inside the support body. The lung organ is placed on the supporting mechanism, the supporting piece 2 is driven by the elastic components 21 to fixedly arrange the lung organ, the activity of the surface of the lung is maintained according to the heating device, and the external component such as an ablation catheter conducts operation experiments on the lung organ in the cavity through the operation window 12.
