Description

Technical Field

[0001] This utility model relates to the field of medical teaching equipment technology, specifically a puncture operation training device for medical teaching. Background Technology

[0002] As is well known, percutaneous puncture technique is also called percutaneous puncture technique. Percutaneous puncture technique is mainly used for various cardiovascular angiography and transvascular interventional treatments that require percutaneous puncture and insertion of catheters.

[0003] Current puncture technique training methods using puncture tubes have significant limitations. To simulate different blood vessel diameters, multiple puncture tubes of different sizes are required. However, once a puncture tube model is selected, its diameter is fixed and cannot be adjusted. During training, trainees cannot flexibly change the puncture tube diameter according to real-time needs. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a puncture operation training device for medical teaching, which solves the problems of traditional puncture tubes having no adjustable diameter, poor practicality, and poor flexibility.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a puncture operation training device for medical teaching, comprising a base, a placement groove with an open top on the base, a puncture tube placed in the placement groove, protruding blocks on both sides of the inner wall of the placement groove, a support plate for supporting the puncture tube inside the placement groove, and a screw threadedly connected to the base, the screw being used to adjust the height of the support plate, the support height of the support plate coordinating with the blocking of the blocks to adjust the diameter of the puncture tube protruding upward through the blocks in the placement groove.

[0008] Furthermore, the top of the base is covered with a leather-like layer.

[0009] Furthermore, the base is provided with a baffle at its edge to restrict the placement of the leather-like layer.

[0010] Furthermore, the base is provided with a plurality of mounting blocks 1, and mounting blocks 2 that attract each other are mounted on the mounting blocks 1. The mounting blocks 1 and mounting blocks 2 attract each other to hold the leather-like layer.

[0011] Furthermore, the base is provided with a mounting groove for storing one side of the lead screw, and the lead screw is provided with a screwing component for rotating the lead screw.

[0012] Furthermore, the base is provided with several slots of different sizes for placing puncture tubes of the same size.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a puncture operation training device for medical teaching, which has the following beneficial effects:

[0015] This medical teaching puncture operation training device, through the setting of a stop block, a support plate and a lead screw, allows the height of the support plate to be adjusted by rotating the lead screw. The support height of the support plate, in conjunction with the blocking action of the stop block, is used to adjust the diameter of the puncture tube protruding upward through the stop block in the placement slot. The operation is simple and labor-saving. Compared with the traditional method of frequently changing different types of puncture tubes, it can quickly meet the needs of different puncture tube protrusion diameters during training, and eliminates the need to purchase a large number of different types of puncture tubes, thus reducing equipment procurement costs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5This utility model discloses a medical teaching puncture operation training device, including a base 1, a placement groove 2 with an open top on the base 1 for placing a puncture tube 5, protruding blocks 6 on both sides of the inner wall of the placement groove 2, a support plate 3 for supporting the puncture tube 5 inside the placement groove 2, a screw 4 threadedly connected to the base 1, the screw 4 being rotatably connected to the support plate 3, an installation groove 8 for storing one side of the screw 4, a screw screw 7 for rotating the screw 4, rotating the screw 4 to adjust the height of the support plate 3, the support height of the support plate 3 coordinating with the blocking of the blocks 6 to adjust the diameter of the puncture tube 5 protruding upward through the blocks 6 in the placement groove 2.

[0024] The puncture tube 5 is made of elastic materials such as plastic and rubber.

[0025] The top of the base 1 is covered with a leather-like layer 10, which is made of rubber. The edge of the base 1 is provided with a baffle 11 to limit the placement of the leather-like layer 10, so as to place the leather-like layer 10 in a suitable position.

[0026] Several mounting blocks 9 are fixedly installed on the base 1. Mounting blocks 9 are mounted on the mounting blocks 9 and mutually attracting mounting blocks 12. The mounting blocks 9 and 12 attract each other to hold the leather-like layer 10 and fix the position of the leather-like layer 10.

[0027] The base 1 is also provided with several different types of placement slots 2 for placing puncture tubes 5 of the same type. The type of placement slot 2 is used to place the most commonly used types of puncture tubes 5.

[0028] In summary, when using this medical teaching puncture operation training device, the puncture tube 5 is placed in the placement slot 2 with the support plate 3. The size of the placement slot 2 is larger than that of other placement slots 2, and the size of the puncture tube 5 inside is larger than that of the puncture tube 5 in other placement slots 2.

[0029] Then, the operator rotates the screw 4 according to the required puncture diameter. The screw 4 causes the support plate 3 to move upward. The support height of the support plate 3, in conjunction with the blocking of the stop block 6, is used to adjust the diameter of the puncture tube 5 in the placement groove 2 as it passes through the upward protrusion of the stop block 6. When the diameter meets the operator's requirements, the leather-like layer 10 is laid on the top surface of the base 1. The leather-like layer 10 is fixed by the mounting block 9 and the mounting block 12. At this time, the operator performs the puncture operation on the puncture tube 5.
