Description

Technical Field

[0001] This utility model relates to the field of medical training equipment technology, specifically to a surgical positioning and placement training model and simulation training device. Background Technology

[0002] Laparoscopic surgery is a newly developed minimally invasive method. It is characterized by a small surgical space, loss of stereoscopic vision, and weakened proprioception, requiring surgeons to develop entirely new hand-eye coordination abilities.

[0003] In the field of medical training, corresponding training models are used to train medical staff's practical skills for different operational skills. Among them, positioning training in laparoscopic surgery is crucial. In existing technologies, the positioning training models have simple structures, and the training results need to be checked and verified by the instructors one by one. This is labor-intensive and relies on subjective observation and judgment. Different people's judgment results vary greatly, making it difficult to objectively and accurately evaluate the training effect of trainees. Utility Model Content

[0004] To address the shortcomings of the existing technology, this invention provides a surgical positioning and placement training model and simulation training device for laparoscopic positioning and placement training, facilitating objective and accurate evaluation of the training effect for trainees.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A surgical positioning and placement training model includes a base plate, a main control board, columns, metal rings, and a power supply. The base plate has at least two different diameter columns, and the number of specifications of the metal rings corresponds to the number of diameter specifications of the columns. The metal rings can be fitted onto the corresponding columns. The base plate at the lower end of the columns has conductive elements, which are two symmetrically arranged metal contacts on both sides of the columns. When the metal rings are fitted onto the columns, the metal rings and the two metal contacts are electrically connected to form a closed circuit. The main control board is located inside the base plate, and the conductive elements are electrically connected to the main control board. The main control board is electrically connected to the power supply. The main control board has a timing module, and the control switch of the timing module is located on the upper surface of the base plate.

[0007] Furthermore, the main control board is equipped with a signal acquisition module, a signal processing module, a data transmission module, and a scoring module.

[0008] Furthermore, there are two types of columns, with three of each type.

[0009] Furthermore, the column is made of a high-strength, insulating, and lightweight material.

[0010] Furthermore, the control switch for the timing module is a metal contact switch.

[0011] A simulation training device using the above-mentioned training model includes a training box, a clamping tool, a laparoscope, a display screen, and a host computer. The training model is positioned and placed inside the training box. The training box has an instrument channel that connects the inside and outside. The clamping tool and the laparoscope extend into the training box from the instrument channel. The main control board, the laparoscope, and the display screen are electrically connected to the host computer.

[0012] Furthermore, the clamping tool includes a separating clamp and a gripping clamp.

[0013] Furthermore, the instrument channel has three channels.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. Standardize training scenarios to reduce practical risks.

[0016] This utility model training model constructs a repeatable and quantifiable training scenario through standardized column dimensions, metal ring specifications, and conductive component layout. Different trainees have completely consistent training conditions on the same model. The model does not rely on real patients or high-cost consumables. Trainees can repeatedly perform cyclical training of setting up, adjusting, and trying again, and master positioning skills in a zero-risk environment.

[0017] 2. Real-time operation feedback enhances awareness of precise positioning.

[0018] This novel training model, through the matching state of the conductive element and the metal ring, can output real-time electrical signals to provide feedback on the accuracy of positioning. When the trainee places the metal ring in place, the main control board can quickly confirm the effectiveness of the operation through signal changes, avoiding the lag and subjectivity of relying on manual visual judgment in traditional training. This instant feedback helps trainees quickly correct operational deviations and reinforces the core requirements of surgical positioning: "size matching and precise positioning," making it particularly suitable for surgical scenarios with extremely high requirements for instrument placement accuracy.

[0019] 3. The process is quantified and visualized, facilitating capability assessment and improvement.

[0020] The timing module integrated into the main control board of this utility model training model can accurately record the time from the start of training to the completion of all positioning operations. Combined with the signal feedback on whether the positioning is accurate, it can objectively quantify the trainee's operational efficiency and accuracy, providing an objective basis for teaching evaluation.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] In the description of the embodiments of this application, it should be noted that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this application is usually placed in when in use, or the orientation or positional relationship that is commonly understood by those skilled in the art. It is only for the convenience of describing this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0027] In the description of the embodiments of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0028] like Figure 1 , Figure 2As shown, a surgical positioning and placement training model includes a base plate 1, a main control board, columns, metal rings, and a power supply. The base plate 1 has at least two different diameter columns, each with a corresponding metal ring of the appropriate diameter. The number of metal ring sizes corresponds to the number of column diameter sizes. The metal rings can be fitted onto the corresponding columns. A conductive element, consisting of two symmetrically arranged metal contacts 2 on both sides of the column, is located on the base plate at the lower end of each column. When the metal ring is fitted onto the column, it forms a closed circuit with the two metal contacts 2. The main control board is located inside the base plate 1. The conductive element is electrically connected to the main control board, which is in turn connected to the power supply. When the circuit formed by the metal ring, conductive element, and main control board is completed, the main control board detects a change in electrical signal. Based on this signal, the main control board determines whether the positioning and placement operation of the simulated object (metal ring) is complete. The main control board is equipped with a timing module. The control switch 3 of the timing module is a metal contact switch located on the upper surface of the base plate 1. At the start and end of training, the training equipment is used to touch the control switch 3 to start and stop the timing module, recording the completion time of the positioning training. This provides an important basis for the main control board to perform comprehensive scoring. To avoid accidental activation, an insulating baffle (such as an ABS plastic ring) can be installed around the contact point.

[0029] In one specific implementation, this application selects the STM32F103RCT6 chip as the core component of the main control board. The main control board integrates a signal acquisition module, a signal processing module, a data transmission module, and a scoring module. The signal acquisition module is used to acquire various electrical signals and send them to the signal processing module. The signal processing module processes the acquired electrical signals. The scoring module scores the training effect based on the data processed by the signal processing module. The data transmission module is used to send the scoring results to the host computer.

[0030] A simulation training device using a surgical positioning and placement training model includes a training box, clamping tools, a laparoscope, a display screen, and a main unit. The positioning and placement training model is placed inside the training box, which has three interconnected instrument channels. The clamping tools include dissecting forceps and grasping forceps. The dissecting forceps, grasping forceps, and laparoscope extend into the training box through their respective instrument channels. The main control board, laparoscope, and display screen are electrically connected to the main unit. The display screen can show the laparoscope image and training data. The training box has a collection slot for placing metal rings. The collection slot is located next to the positioning and placement training model. Before and after training, the metal rings are collected in the collection slot for easy retrieval during training.

[0031] like Figure 2As shown, in this embodiment, there are two types of columns: three thick columns 4 and three thin columns 5. The thick columns 4 are matched with large metal rings 6, and the thin columns 5 are matched with small metal rings 7. The six columns are labeled as column A, column B, column C, column D, column E, and column F in sequence, and all are made of high-strength, insulating, and lightweight materials. During operation training, the laparoscope is first inserted into the training box through the instrument channel, the field of view is adjusted and fixed, one hand holds the separation forceps and the other holds the grasping forceps, and enters the training box through the instrument channel. The grasping forceps head touches the control switch 3 of the timing module to start the timer. Then, the grasping forceps are used to grab the metal ring in the collection tank and transfer it to the separation forceps, and the metal ring is placed on the corresponding column. If the placement is correct, the metal ring, conductive element and main control board will form a closed loop. The main control board determines and records that one placement operation has been completed. Place the columns in the order of AF. After passing the test, touch the control switch 3 of the timing module with the gripper head. At this time, the positioning and placement operation is considered to be completed, the timing module stops timing, the system automatically ends and scores based on the accuracy of positioning and placement and the completion time, and reports the score data to the cloud or the display.

[0032] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
