Description

Technical Field

[0001] The present invention belongs to the technical field of medical models, and in particular relates to a partially detachable and replaceable abdominal puncture scoring training model. Background Art

[0002] In the fields of medical teaching and scientific research, clinical internships and clinical operation training are often carried out. In order to avoid direct operation training on the human body, the common practice now is to use models for operation training;

[0003] The abdominal puncture training model is one of the commonly used training models, but most of the existing models are integrated, bulky, and easy to breed bacteria. In addition, repeated puncture training of the model can easily lead to damage to the skin structure of the local puncture point. If the model is not replaced, it will affect the puncture feel and cause inadequate puncture training. Replacing the model requires replacing the entire model, and the cost of maintenance and replacement is high. Therefore, it is necessary to propose an abdominal puncture scoring training model that can be partially disassembled and replaced to facilitate local replacement of the skin at the puncture point. Utility Model Content

[0004] In view of the deficiencies of the prior art, the purpose of the present invention is to provide a partially detachable and replaceable abdominal puncture scoring training model to facilitate local replacement of the skin at the puncture point.

[0005] The purpose of this disclosure can be achieved through the following technical solutions:

[0006] A partially detachable and replaceable abdominal puncture scoring training model, comprising:

[0007] A torso model, wherein a round hole is opened on the torso model, and the round hole is a blind hole;

[0008] A sliding shaft block is slidably engaged in the circular hole, one end of the sliding shaft block is connected to a driving member used to drive it to move along the circular hole, the driving member is arranged at the bottom of the circular hole, and one end of the sliding shaft block away from the driving member is provided with a puncture groove coaxially arranged;

[0018] A plurality of evenly distributed convex strips are fixed on the peripheral wall of the circular hole, and the convex strips are placed coaxially with the circular hole. A plurality of evenly distributed sliding grooves are opened on the peripheral wall of the sliding shaft block, and the sliding grooves correspond to the convex strips one by one and are slidably connected therewith.

[0019] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0020] Connection: refers to the process of connecting two separate profiles or parts into a complex part or component using fasteners such as screws, bolts and rivets.
