Detailed Description

The present application will be described in further detail below with reference to the accompanying drawings by way of specific embodiments.

The application provides a model for amputation training, in particular a model for amputation training of an operator, so that the operator is skilled in the amputation process.

Referring to fig. 1 and 2, the model for amputation training provided in this embodiment mainly includes: a limb substitute 10, a first main conduit 20, a second main conduit 30, a wire 40, a first pressurizer 50 and a second pressurizer 60.

The limb substitute 10 is, as the name implies, an article for replacing a limb, the limb substitute 10 having an organizational structure consistent with an actual limb, such as: simulated cortex, simulated bone, etc. In one embodiment, the limb substitute 10 is an animal limb. The animal limb is in particular a dead animal limb, more in particular a limb of a human domesticated, dead animal, such as: pig limbs, sheep limbs, cow limbs, etc., and pig hands are used in this example. In another embodiment, the limb replacement 10 comprises a stem 11 for simulating bone and a silicone sleeve 12 for simulating cortex, the silicone sleeve 12 being wrapped around the stem 11. The rod 11 may be a plaster rod, a plexiglas rod, or the like.

First main pipeline 20, second main pipeline 30 and wire 40 are used for setting up in limbs substitute 10, and specifically first main pipeline 20, second main pipeline 30 and wire 40 set up in limbs substitute 10's cortex, the direction of extension of first main pipeline 20, second main pipeline 30 and wire 40 in the cortex is the same with limbs substitute 10's direction of extension, in other words, the length direction of first main pipeline 20, second main pipeline 30 and wire 40 in the cortex is the same with limbs substitute 10's length direction. The first main conduit 20 is used to simulate veins, the second main conduit 30 is used to simulate arteries, and the wire 40 is used to simulate nerves. In this embodiment, the first main conduit 20 and the second main conduit 30 are infusion conduits and the wire 40 is a surgical suture. Therefore, the model has the advantages of convenient material acquisition and low cost.

The first pressurizer 50 communicates with one end of the first main pipe 20, and the second pressurizer 60 communicates with one end of the second main pipe 30. A first liquid is sealed in the first pressurizer 50 and the first main pipe 20, and a second liquid is sealed in the second pressurizer 60 and the second main pipe 30, that is, the other end of the first main pipe 20 is sealed, and the other end of the second main pipe 30 is sealed. As shown in fig. 1, during an amputation in direction a-a, the first liquid in the first main conduit 20 and the first pressurizer 50 flows out from the cut-out of the first main conduit 20, and the second liquid in the second main conduit 30 and the second pressurizer 60 flows out from the cut-out of the second main conduit 30. Because the first main pipe 20 and the second main pipe 30 simulate veins and arteries respectively, in order to distinguish the effect of bleeding after the simulation of the veins and the arteries and amputation, the color of the first liquid and the color of the second liquid can be set to be different, specifically, the color of the first liquid is blue, the color of the second liquid is red, and of course, the colors of the first liquid and the second liquid can also be set to be other colors respectively.

During amputation, the first pressurizer 50 is used to apply pressure to achieve the first liquid ejection effect, and the second pressurizer 60 is used to apply pressure to achieve the second liquid ejection effect. The second pressurizer 60 applies a greater pressure to the second main conduit 30 than the first pressurizer 50 applies to the first main conduit 20 to better simulate the arteriovenous. In some embodiments, the first and

second pressurizers

50 and 60 may be conventional fluid bags that are squeezed to apply pressure during amputation; in some embodiments, the first and

second pressurizers

50 and 60 may also be infusion pressurizing bags. In still other embodiments, the first pressurizer 50 and the second pressurizer 60 may be booster pumps. In this embodiment, the first and

second pressurizers

50 and 60 are infusion pumps, which can accurately control the pressure to simulate different blood pressures. Therefore, the pressurizer is convenient to take materials.

The amputation training model provided in this embodiment is a disposable product, that is, the limb substitute 10, the first main pipe 20, the second main pipe 30 and the wire 40 as a whole are disposable products, and for saving the manufacturing cost of materials, the model further includes: a first sub-pipe 51 and a second sub-pipe 61, the first sub-pipe 51 being connected between the first pressurizer 50 and one end of the first main pipe 20, i.e., one end of the first main pipe 20 is communicated with an outlet of the first pressurizer 50 through the first sub-pipe 51; the second sub pipe 61 is connected between the second pressurizer 60 and one end of the second main pipe 30, that is, one end of the second main pipe 30 communicates with the outlet of the second pressurizer 60 through the second sub pipe 61. When a limb is amputated, the pressure to which the blood in the vein and artery of the patient is subjected is different, and correspondingly, the flow rate of the blood flowing out of the vein and artery of the patient after amputation is different, in order to ensure the authenticity of the amputation training process, the model for amputation training provided by the embodiment further comprises: a first speed governor 52 and a second speed governor 62, the first speed governor 52 being disposed on the first sub-pipe 51, the second speed governor 62 being disposed on the second sub-pipe 61. During amputation training, the first speed regulator 52 is used for regulating the flow rate of the first liquid flowing out of the cut-out of the first main pipe 20, and the second speed regulator 62 is used for regulating the flow rate of the second liquid flowing out of the cut-out of the second main pipe 30, so as to achieve a more real amputation effect. Wherein, the first speed regulator 52 and the second speed regulator 62 both adopt transfusion switch clamps, and have the characteristics of convenient material acquisition and low cost.

In some embodiments, after the amputation training of the present model, the first main conduit 20 and the first sub-conduit 51 are separated, and the second main conduit 30 and the second sub-conduit 61 are separated, so that the first sub-conduit 51, the second sub-conduit 61, the first pressurizer 50 and the second pressurizer 60 can be reused.

Further, after the amputation training is abandoned, in the process of amputation training using another amputation model, in order to ensure the quick connection between the first sub-pipe 51 and the second sub-pipe 61 and the first main pipe 20 and the second main pipe 30 in the other amputation model, the amputation model further comprises: a first connector 53 and a second connector 63, the first connector 53 being for quick connection of the first subduct 51 and one end of the first main duct 20, the second connector 63 being for quick connection of the second subduct 51 and one end of the second main duct 30.

second connectors

53 and 63 may be quick connectors to achieve quick and convenient connection. The first and

second connectors

53 and 63 may also be valves to control the connection and disconnection between the first sub-pipe 51 and the first main pipe 20 and between the second sub-pipe 61 and the second main pipe 30, respectively.

In another embodiment, on the premise of not considering the material manufacturing cost, the first sub-pipe 51 and the first main pipe 20 are of an integrated structure, that is, they are a liquid conveying pipe; the second sub-pipe 61 and the second main pipe 30 are of an integrated structure, and are a liquid conveying pipe.

As shown in fig. 3, the model for amputation training provided by the present embodiment further includes: the artificial limb prosthesis comprises a first splint 70, a second splint 80 and a dummy model 90, wherein the first splint 70 and the second splint 80 are arranged on a limb substitute 10, specifically, one end of the first splint 70 and one end of the second splint 80 are clamped and fixed on the limb substitute 10, and the other end of the first splint 70 and the other end of the second splint 80 are clamped and fixed on the dummy model 90. More specifically, the dummy 90 is a dummy lacking at least one limb, and the other end of the first splint 70 and the other end of the second splint 80 are secured to the at least one limb that the dummy lacks for more realistic amputation training. In this embodiment, the model simulates a part of a lower limb, one end of which is clamped to the leg of the dummy by two clamping plates, and the other end of which is clamped to the bare foot of the dummy by two other clamping plates, and the other part of the lower limb is the same as the other lower limb.

In some embodiments, the parts of the model exposed outside the limb substitute 10, such as the first pressurizer 50, the second pressurizer 60, the first sub-pipe 51, the second sub-pipe 61, the first speed regulator 52, the second speed regulator 62, the first connecting piece 53 and the second connecting piece 63, are arranged in the dummy model body, such as the chest cavity and/or the abdominal cavity of the dummy model, and the simulation degree is higher.
