Problems solved by technology

Through the puncture training module made in a superimposed manner, since the tissues of each layer are independent, it is difficult to ensure the close fit between different tissues when superimposed and combined, so it is difficult to ensure that the puncture needle is The needle insertion depth before entering the spinal canal is consistent with the design needle insertion depth, which affects the effect of puncture training

specific Embodiment 2

[0047] Specific embodiment 2 The simulated lumbar vertebrae described in this embodiment, such as Figure 2~3 Shown is a 3D printed complete simulated lumbar vertebra (20) with vertebrae 1 to 5. A shallow groove (27) is set on each spinous process of the first vertebra (21) to the fifth vertebra (22) of the 3D printed artificial lumbar vertebra (20), and the position of the shallow groove (27) is At 11mm away from the top of each spinous process, the shallow groove (27) has a height and depth of 1mm. Cylinders (25) are respectively arranged on both sides of each spinous process, and a 1mm annular shallow groove (26) is opened at a place 1mm away from the top of the cylinder (25). Open 1mm shallow grooves (26) on the cylinders (25) arranged on both sides of each spinous process, the purpose is to fix the simulated ligamentum flavum (60) on the simulated lumbar vertebrae (20), and pass 3 shallow grooves (26) on each vertebrae. The groove is used to fix the simulated ligamentum...

Embodiment 3

[0050] Example 3 as figure 2 and Figure 4 As shown, the simulated puncture tube described in this embodiment includes a simulated dura mater (51) and a simulated spinal canal (52), and the simulated puncture tube (50) is set on the 3D printed simulated lumbar vertebra ( 20) in the "C" type fixed structure 231). In this embodiment, the materials used for the simulated dura mater (51) and the simulated spinal canal (52) are soft materials. The soft material is specifically a latex tube and a silicone tube, the latex tube is used to simulate the simulated dura mater (51) in the simulated puncture tube, and the silicone tube is used to simulate the simulated spinal canal (51) in the simulated puncture tube ( 52). The size of the latex tube is 148mm in length and 14*18mm in diameter, and the size of the silicone tube is 140mm in length and 8*11mm in diameter. The silicone tube is sleeved in the latex tube, one end is blocked with a T-shaped silicone plug (53), and one end is ...

Abstract

The invention discloses a lumbar puncture training module which comprises a simulation outer skin, a simulation lumbar vertebra bone, simulation supraspinal ligament and simulation interspinous ligament and a simulation subcutaneous tissue, and is characterized in that a simulation ligamentum flavum and a simulation puncture tube are arranged on the simulation lumbar vertebra bone; the simulation puncture tube is arranged in an entocoele of the simulation lumbar vertebra bone, and the simulation puncture tube comprises a simulation spinal canal and a simulation spinal dura mater; the simulation ligamentum flavum is arranged in an exocoel of the simulation lumbar vertebra bone; the simulation lumbar vertebra bone is wrapped on the simulation supraspinal ligament and interspinous ligament, the simulation supraspinal ligament and interspinous ligament is wrapped in the simulation subcutaneous tissue; and the simulation subcutaneous tissue is wrapped by the simulation outer skin. The manufacturing method of the module is an integrated forming manufacturing method, the problems of needle inserting hand feeling and needle inserting accuracy during lumbar puncture training are solved, and replacement of the puncture module is facilitated.

Description

technical field [0001] The application belongs to the field of medical education, and in particular relates to a lumbar puncture training module and a manufacturing method thereof. Background technique [0002] At present, the production of existing medical teaching models related to puncture training is basically composed of superimposed single-layer tissues. In the production process of the lumbar puncture training module, the prepared lumbar vertebrae, skin layer, subcutaneous tissue, supraspinous ligament, interspinous ligament, ligamentum flavum, dura mater, arachnoid, etc. are generally combined to form Lumbar puncture module. The cavity between the dura mater and arachnoid is supported by placing a spring or a ring-shaped support structure to ensure that the dura mater Invasion does not occur. Through the puncture training module made in a superimposed manner, since the tissues of each layer are independent, it is difficult to ensure the close fit between different...
