DETAILED DESCRIPTION

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-4 As shown, a purse-string suture practice mold for medical teaching includes a table 1 with a placement groove 2 on the table 1. A mold 3 is placed in the placement groove 2. The mold 3 includes skin tissue 4 and an abdominal cavity 5. The skin tissue 4 is divided into multiple layers from the outside to the inside: skin layer 41, subcutaneous tissue layer 42, abdominal wall muscle layer 43, and peritoneum layer 44. The peritoneum layer 44 is fixedly connected to the abdominal cavity 5. An insertion component 6 is provided on the outer wall of the skin tissue 4. The skin tissue 4 is made of silicone material to simulate the condition of human skin. The insertion component 6 connects the layers in series while preventing the corners of the layers from curling up.

[0023] In this embodiment, a circular hole 7 is provided on the skin tissue 4 to indicate the location of the navel. The circular hole 7 indicates the location of the navel and can provide a reference for the location where the patient's skin is cut.

[0024] In this embodiment, storage tanks 8 for storing red dyeing solution are provided inside the skin tissue 4 and at the incision site. When the skin tissue 4 is cut, the red dyeing solution in the storage tank 8 can overflow, causing some obstruction and influence on the patient's vision and operation, thereby simulating the bleeding situation of the patient during the operation.

[0025] In this embodiment, a threaded hole 9 extending to the peritoneum layer 44 is provided on the skin tissue 4. An elastic ball 10 is fixed on the inner bottom wall of the threaded hole 9. When the threaded rod is screwed into the threaded hole 9, the deformation of the elastic ball 10 can exert a certain pushing effect on the threaded rod, thereby reducing the spacing between the threads and making the connection between the layers more stable. Different lengths of threaded rods can be selected for connection according to the number of layers being practiced.

[0026] In this embodiment, the threaded hole 9 is not connected to the storage tank 8 and does not interfere with the opening position.

[0027] In this embodiment, the plug-in component 6 includes a locking block 61, a through slot 62 is provided on the locking block 61, an L-shaped lever 63 is fixed on the side wall of the adjacent layer to which the locking block 61 is fixed, a triangular block 64 is fixed on the L-shaped lever 63, and the adjacent layers can be fixedly connected when the triangular block 64 is inserted into the locking block 61.

[0028] In this embodiment, a plurality of support frames 11 are fixed on the top surface of the table 1.

[0029] It needs to be explained that the utility model discloses a purse suture practice mold for medical teaching, when using, the threaded rod is screwed into the threaded hole 9, and the elastic ball 10 can be deformed to push the threaded rod, so that the gap between the threads can be reduced, the connection between each layer is more stable, when the L-shaped push block 63 enters the through slot 62 on the clamping block 61, the inner wall of the through slot 62 extrudes the hypotenuse of the triangular block 64, so that the L-shaped push block 63 is bent under stress, until the triangular block 64 passes completely, the L-shaped push block 63 resets and completes clamping, so that the problem of corner lifting can be prevented, when the skin tissue 4 is cut, the red dyeing liquid stored in the inner storage groove 8 is spilled, the vision and operation of the trainee are influenced, the bleeding condition of the patient during operation is simulated, and the practice is more effective.

[0030] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above. It should be understood by those skilled in the art that the utility model is not limited by the above-mentioned embodiments, and the above-mentioned embodiments and the description in the specification only illustrate the principle of the utility model, various changes and improvements can be made to the utility model without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed. The scope of protection of the utility model is defined by the appended claims and their equivalents.
