Description

Technical Field

[0001] The utility model relates to the technical field of surgical training models, in particular to a surgical training and assessment model for practicing physicians. Background Art

[0002] Surgery is an important branch of medicine, which mainly treats various diseases, traumas and physical abnormalities through surgery. Surgeons are responsible for removing, repairing or reconstructing lesions during the operation. Since surgery is indispensable for surgeons, the assessment of practicing surgeons requires the use of dummy models to assess surgical operations.

[0003] Prior art, Chinese patent publication number CN213904687U discloses a wearable surgical training and assessment model for practicing physicians. The model includes a chest and abdominal skin model with a drape disinfection module mounted on top. A superficial tumor incision and suturing module is located adjacent to the drape disinfection module. A suture removal and dressing change module is located below the superficial tumor incision and suturing module, and a debridement and suturing module is located above the superficial tumor incision and suturing module. This model can be used for national practicing physician examinations, physician training, and practical exercises. The model can be placed on a real person or any mannequin, and then procedures performed on the skin model.

[0004] Based on the above materials, it can be seen that the existing technology generally uses operations on dummy models to achieve the purpose of training and assessment. However, in actual use, after operations (such as surgery, bandaging, etc.) on simple dummy models, the accuracy of the operations needs to be judged by the naked eye, and certain errors may occur in the naked eye judgment. Utility Model Content

[0005] The purpose of the present invention is to provide a surgical training and assessment model for practicing physicians, so as to solve the problem of possible errors in naked eye judgment raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a surgical training and assessment model for practicing physicians, comprising a horizontally placed support base, a corresponding placement platform provided directly above the support base, and further comprising:

[0007] A square mounting block is fixedly mounted on the upper surface of the placement table, and a silicone dummy model simulating a patient's chest is mounted above the mounting block, and a positioning slot is provided below the dummy model to engage with the mounting block, and an electrode plate is mounted above the mounting block;

[0008] The mannequin is internally provided with simulated blood vessels for simulating the disordered blood vessels in the human body;

[0009] A mounting frame is fixedly installed at the rear of the placement table, and an identification camera for identifying faces and a monitoring camera for monitoring the operation process are fixedly installed on the upper end of the mounting frame.

[0010] Preferably, a telescopic cylinder is fixedly installed between the support base and the lower surface of the placement table, and the placement table is adjusted from above by the telescopic cylinder.

[0011] Preferably, fixing balls are fixedly installed on the left and right sides of the mounting block, and the fixing balls are correspondingly engaged with the fixing grooves provided on the inner wall of the positioning groove.

[0012] Preferably, a first connecting wire for supplying power to the electrode plate is fixedly mounted on the lower surface of the electrode plate, and the first connecting wire is connected to the negative electrode of the battery module fixedly mounted on the upper surface of the placement table.

[0013] Preferably, the positive pole of the battery module is connected to a second connecting wire, and an internally conductive scalpel is installed at the front end of the second connecting wire.

[0014] Preferably, a docking port is fixedly installed on the left outer surface of the dummy model, and the docking port is communicated with the simulated blood vessel.

[0015] Preferably, the docking port and the delivery tube are inserted and snap-fitted, and the delivery tube is communicated with the delivery pump outlet fixedly mounted on the upper surface of the placement table, and the delivery pump inlet is connected to a pipeline for delivering simulated blood.

[0016] Compared with the existing technology, the beneficial effects of the present invention are as follows: the surgical training and assessment model for practicing physicians adopts a new structural design, and its specific contents are as follows:

[0017] 1. Install the dummy model on the mounting block to operate the scalpel for training or assessment. At the same time, the telescopic cylinder is activated to drive the placement table up and down to the appropriate height, making it suitable for operators of different heights.

[0018] Furthermore, during the assessment, identification cameras are used to identify the operator's identity, thereby assisting in recording scores. At the same time, monitoring cameras can record the entire operation process to facilitate subsequent review.

[0019] 2. When the user is operating the scalpel, if the scalpel cuts too deep, it will touch the electrode plate. When the scalpel touches the electrode plate, a complete circuit is formed. At this time, the electrical signal is transmitted to the control computer, which determines that the operator has made an operational error. The electrical signal replaces the naked eye observation, thus improving the accuracy.

[0020] Furthermore, corresponding simulated blood vessels are embedded in the interior of the heating model. When the operator cuts the simulated blood vessels, bleeding will occur, thereby achieving a more realistic feeling and more accurately reflecting the operator's operation.

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figures 1-4In order to achieve the purpose of simulated operation, this embodiment provides the following technical solutions, which specifically disclose: a horizontally placed support base 1, a corresponding placement platform 2 is arranged directly above the support base 1, a square mounting block 3 is fixedly installed on the upper surface of the placement platform 2, and a silicone mannequin 4 simulating a patient's chest is installed above the mounting block 3, and a positioning groove 5 is provided below the mannequin 4 to be engaged with the mounting block 3, a telescopic cylinder 6 is fixedly installed between the support base 1 and the lower surface of the placement platform 2, and the placement platform 2 is adjusted from above the telescopic cylinder 6, and fixed balls 8 are fixedly installed on the left and right sides of the mounting block 3, and the fixed balls 8 are engaged with the fixed grooves 9 provided on the inner wall of the positioning groove 5.

[0031] When using the device, first open the telescopic cylinder 6 according to the operator's height, and use the telescopic cylinder 6 to adjust the height of the placement table 2. Then place the dummy model 4 on the placement table 2, and use the positioning groove 5 below the dummy model 4 to dock and engage with the mounting block 3. At the same time, use the fixing balls 8 on the left and right sides of the mounting block 3 to engage and fix with the fixing groove 9 inside the positioning groove 5. After the fixation is completed, the operator can pick up the scalpel 7 to perform simulated surgical operations to achieve the purpose of training or assessment.

[0032] See also Figure 5 In order to solve the problem that traditional devices are prone to errors when observed with the naked eye, this embodiment provides the following technical solution, which determines whether an operational error occurs through electrical signals. Specifically, it is disclosed that: an electrode plate 10 is installed above the mounting block 3, and a first connecting wire 12 for powering the electrode plate 10 is fixedly installed on the lower surface of the electrode plate 10, and the first connecting wire 12 is connected to the negative pole of the battery module 11 fixedly installed on the upper surface of the placement table 2, and the positive pole of the battery module 11 is connected to the second connecting wire 13, and the front end of the second connecting wire 13 is installed with an internal conductive scalpel 7.

[0033] When the operator's scalpel 7 cuts too deep, the scalpel 7 will pass through the dummy model 4 and contact the electrode plate 10, forming a complete circuit under the connection of the battery module 11, the first connecting wire 12 and the second connecting wire 13, realizing the flow of electrical signals. At this time, the control computer detects the electrical signal, determines that the operator has made an operational error and records it.

[0035] During simulation training, the delivery pump 17 is turned on. At this time, the delivery pump 17 delivers simulated blood to the simulated blood vessel 14 through the delivery tube 16 (the delivery tube 16 is inserted into the docking port 15 to complete the connection). When the operator cuts off the simulated blood vessel 14 during simulation, bleeding will occur, which can achieve a more realistic effect. When an assessment is required, the recognition camera 19 is first turned on, and the recognition camera 19 is used to perform facial recognition on the operator, determine and record the identity, and at the same time, the monitoring camera 20 is turned on to shoot the operation process for convenience of subsequent review.
