Technical Field

[0001] This application relates to the field of virtual surgery technology, and in particular to a puncture device for virtual simulation training. Background Technology

[0002] A laparoscopic simulator is a highly realistic training tool for minimally invasive surgery, primarily used for skills training by doctors and medical students. By simulating a real surgical environment and procedure, it helps medical professionals improve their surgical skills and reduce errors and complications in actual operations. With the popularization of minimally invasive surgical techniques and advancements in medical education, the laparoscopic simulator market is experiencing rapid growth.

[0003] Existing laparoscopic simulators are typically used in conjunction with a training platform. However, these training platforms are usually quite large, requiring a significant area for multiple users. Furthermore, since laparoscopic simulators are usually paired with training platforms, they cannot be easily replaced. When the usage scenario changes, the entire training platform often needs to be replaced, resulting in low training efficiency for operators. Utility Model Content

Obviously, the described embodiments are merely one embodiment of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

Thus, a feature defined with "first," "second," and "third," etc., may explicitly or implicitly include one or more of that feature. Furthermore, the terms "first," "second," and "third," etc., are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

Moreover, the terms "comprising" and "being," and any variations thereof, are intended to cover non-exclusive inclusion.

[0022] like Figure 1 As shown, this embodiment provides a virtual simulation training puncture device. The puncture device includes a puncture rod 1 and a housing 2. The puncture rod 1 is hollow inside and detachably connected to the housing 2. The puncture rod 1 can accommodate the passage of a testing instrument. The puncture device provided in this embodiment is typically used for simulation training of laparoscopic surgery. The puncture rod 1 is connected to the inside of the housing 2. The operator holds the laparoscopic instrument and inserts it into the puncture rod 1 through the through hole at the upper end of the housing 2, thereby simulating the use scenario of laparoscopic surgery.

[0023] like Figure 2As shown, in some application scenarios, the puncture device provided in this embodiment is inserted into the training platform 3 to achieve simulation training. The training platform 3 is provided with working holes for puncture device insertion. To improve the efficiency of simulation, the training platform 3 in this embodiment is provided with multiple working holes, which can accommodate multiple puncture devices simultaneously for simultaneous simulation training. In some other embodiments, the multiple puncture devices can be different types of laparoscopic simulation instruments. This can meet more application scenarios and achieve more efficient training results.

[0024] like Figure 3 As shown, the housing 2 includes a first housing 21 and a second housing 22 that are detachably connected. An accommodating space 23 is provided between the first housing 21 and the second housing 22. A first detection unit 24 and a second detection unit 25 are provided on the first housing 21. The first detection unit 24 is used to detect the linear movement of the endoscopic instrument, and the second detection unit 25 is used to detect the rotational movement of the endoscopic instrument. In this embodiment, the endoscopic instrument is inserted into the housing. During the insertion and continued movement, it is necessary to record the length of movement and the angle of rotation of the endoscopic instrument. Therefore, by collecting the movement process of the endoscopic instrument in real time through the first detection unit 24 and the second detection unit 25, the movement distance and rotation angle of the endoscopic instrument can be obtained.

[0025] like Figure 4-5As shown, to achieve better signal acquisition, a first through hole 26 along a first direction is provided on the first housing 21 in this embodiment. The endoscopic instrument can move linearly and rotate within the first through hole 26. A second through hole 27 along a second direction is also provided on the first housing 21, and the second through hole 27 communicates with the first through hole 26. Thus, the first detection unit 24 or the second detection unit 25 can be installed in the second through hole 26 to detect the moving distance and rotation angle of the endoscopic instrument in real time. In this embodiment, to better record the moving distance and rotation angle, the first detection unit 24 for detecting the moving distance of the endoscopic instrument can be a laser sensor, and the second detection unit 25 for detecting the rotation angle of the endoscopic instrument can be a laser sensor or an attitude sensor. An attitude sensor is configured within the accommodating space. To better install the first detection unit 24 and the second detection unit 25, a mounting groove 28 is also provided in the first housing 21. The mounting groove 28 is a recessed groove on the first housing 21, and its size is adapted to the size of the first detection unit 24 and the second detection unit 25. In order to ensure that the first detection unit 24 and the second detection unit 25 can be stably assembled while accurately detecting the signal of the movement of the endoscopic instrument, a pair of mounting grooves are provided in this embodiment, which are respectively installed on both sides of the first through hole 26. In this way, the straight-line distance between the first detection unit 24 and the second detection unit 25 is the greatest, and the interference between signals is the weakest. Thus, after the first detection unit 24 and the second detection unit 25 are stably assembled, the signal interference can be guaranteed.

[0026] During the movement of the endoscopic instrument, the distance and angle of movement of the endoscopic instrument are recorded in real time by a laser sensor and / or an attitude sensor, and the distance and angle data are sent to the controller. With the help of virtual simulation 3D simulation technology, the movement distance and rotation angle of the endoscopic instrument can be obtained in real time. The laser sensor, attitude sensor and virtual simulation 3D simulation technology mentioned in this embodiment are all existing technologies in the field, and will not be described in detail in this embodiment.

[0027] like Figure 4-5 As shown, the puncture rod 1 has a third through hole 11, which communicates with the first through hole 26. The laparoscopic instrument can move from the first through hole 26 into the third through hole 11. To ensure that the laparoscopic instrument can be better inserted into the first through hole 26, a chamfer 261 is provided at the beginning of the first through hole 26. The diameter of the chamfer 261 is larger than the diameter of the first through hole 26, which facilitates the operator to quickly insert the laparoscopic instrument. The outer shell of the second housing 22 is also provided with an anti-slip area with protruding edges. During use, the operator holds the anti-slip area of ​​the second housing with one hand and inserts the laparoscopic instrument through the chamfer 261 with the other hand, making the operation very convenient.

[0028] The above embodiments are merely illustrative of the technical concept and features of this application, intended to enable those skilled in the art to understand the content of this application and implement it accordingly, and should not be construed as limiting the scope of protection of this application. It is obvious to those skilled in the art that this application is not limited to the details of the above exemplary embodiments, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this application is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of the equivalents of the claims are intended to be included within this application.
