Description

Technical Field

[0001] The utility model belongs to the field of medical technology, and in particular relates to a laparoscopic blood vessel ligation and suturing training device. Background Art

[0002] With the development of minimally invasive surgery concepts and the advancement of equipment, laparoscopic surgery is increasingly being used in various surgical operations, especially abdominal surgery (including surgery on organs such as the liver, gallbladder, pancreas, stomach, intestines, kidneys, ureters, and bladder). During the operation, in order to achieve the purpose of removing the lesion, we first need to free the lesion and some important organs. Due to the wide distribution of vascular systems at all levels, the freeing and ligation of blood vessels are often the key to determining the success of our operation. The tension of blood vessels of different grades and types varies due to the different thickness of the tube wall; the tension of the same type of blood vessels in different patients also varies due to the different degrees of sclerosis of the blood vessels. In laparoscopic surgery, the ligation and suturing of blood vessels are usually performed by the surgeon using laparoscopic instruments to clamp vascular clips or suture needles and threads. The requirements of this process are very delicate. Experienced doctors can generally complete it smoothly with caution and caution with their many years of operating experience. Of course, there are also cases where the tension of the blood vessels exceeds its limit during the operation, resulting in damage and subsequent heavy bleeding. If this is the case for experienced doctors, then for inexperienced doctors, it is more likely to cause vascular damage due to inappropriate pulling force during the operation. Blood vessel damage can cause bleeding, which can affect the clarity of the surgical field and prolong the operation time. However, damage to small vessels or large blood vessels that are not easily detected can often lead to serious consequences, including massive bleeding, secondary surgery, or even death. In order to reduce the above risks, it is very important to increase the experience of the surgeon.

[0003] In the traditional medical training model, the way to increase experience is to participate in more surgeries and conduct experiments on animals, but such opportunities are limited. With the advancement of medicine, many different types of laparoscopic simulation trainers have undoubtedly brought better training opportunities for young doctors. Most of the existing laparoscopic simulators on the market are structured to place a silicone block simulating internal organs in a cavity box, and open multiple holes on the upper surface of the cavity box. A camera is placed in one of the holes, and the image taken by the camera is used to simulate the image of the surgical monitor. The other holes can be inserted with surgical instruments to perform simulated surgical operations on the silicone block. This training mode is mainly aimed at tissue shearing and suturing, and cannot accurately simulate the application scenarios of tube ligation and suturing, and cannot perform targeted training; in addition, the existing simulators can only display images, and cannot provide force feedback, resulting in poor training results. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a laparoscopic vascular ligation and suturing training device, which is used to solve the technical problems that the existing laparoscopic simulation trainer cannot perform targeted vascular ligation and suturing and can only display images but cannot provide force feedback, resulting in poor training effects.

[0005] The utility model provides the following technical solution: a laparoscopic vascular ligation and suturing training device, comprising a training device body, the training device body comprising a box, a monitoring component arranged in the box, and a display screen installed on the top of the box, the monitoring component comprising a bottom plate detachably arranged in the box, two tension sensing members symmetrically arranged on the top of the bottom plate, a limiting member installed on the tension sensing member, and a control module electrically connected to the tension sensing member, the two limiting members are respectively used to limit the two ends of the simulation tube to limit the simulation tube in the box, the control module is electrically connected to the display screen, the tension sensing member is used to monitor the tension signal of the simulation tube, and transmit the tension signal to the control module, the control module is used to determine whether the tension signal exceeds a threshold value, and transmit the result of the determination and the tension value corresponding to the tension signal to the display screen for display.

[0006] Compared with the prior art, the beneficial effects of the utility model are: first, the bottom plate is taken out of the box, and then the two ends of the simulation tube are respectively connected to the limit members to fix the simulation tube above the bottom plate, and then the bottom plate is placed in the box, and then the threshold is adjusted to a suitable position, and then the operator uses the simulation operating lever to perform ligation and suturing training. At this time, the tension sensing member monitors the tension signal of the simulation tube in real time, and transmits the tension signal to the control module, and the control module transmits the pressure value corresponding to the tension signal to the display screen for display. At the same time, the control module is used to determine whether the tension signal exceeds the threshold. If too much force is applied during the operation, and the tension signal exceeds the threshold, the control module sends a warning signal to the display screen. It can be seen that by monitoring the tension signal of the simulation tube in real time through the tension sensing member, the specific force of the trainee during the operation can be known in real time, and the trainee can be warned by setting the threshold, thereby improving the training effect.

[0007] Furthermore, the limiting member includes a shell, a limiting cavity is opened inside the shell, and the limiting cavity passes through one end and one side of the shell, a rotating plate is provided on the side through which the shell is passed, a limiting strip is provided at the bottom of the rotating plate, and the rotating plate can be rotatably set on the shell so that the limiting strip is in the limiting cavity or in the limiting cavity. When the limiting strip is in the limiting cavity, the simulation tube placed in the limiting cavity is limited.

[0008] Furthermore, an elastic telescopic member is disposed on one side of the shell, and the elastic telescopic member is used to limit the rotation plate so that the limiting bar is limited to be located in the limiting cavity.

[0009] Furthermore, the elastic telescopic member includes a groove formed on the housing and a movable plate connected to the groove via a spring.

[0010] Furthermore, the top of the box body is covered with a cover plate.

[0011] Furthermore, a slide groove is provided on the side wall of the box body, a slider is provided in the slide groove, the slider is connected to the bottom plate, and the slide groove passes through the top of the box body so that the slider can move in the slide groove.

[0013] Furthermore, the simulation tube is a latex tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] See also Figure 1 to Figure 2As shown, a laparoscopic vascular ligation and suturing training device in an embodiment of the utility model is used to simulate laparoscopic simulation tube 40 ligation and suturing training, including a training device body 100, the training device body 100 includes a box 10, a monitoring component 20 arranged in the box 10, and a display screen 30 installed on the top of the box 10, the monitoring component 20 includes a bottom plate 21 detachably arranged in the box 10, two tension sensing members 22 symmetrically arranged on the top of the bottom plate 21, a limiter 23 installed on the tension sensing member 22, and an electrical connection In the control module 24 of the tension sensing member 22, the two limiting members 23 are respectively used to limit the two ends of the simulation tube 40 to limit the simulation tube 40 in the box body 10. The control module 24 is electrically connected to the display screen 30. The tension sensing member 22 is used to monitor the tension signal of the simulation tube 40 and transmit the tension signal to the control module 24. The control module 24 is used to determine whether the tension signal exceeds a threshold value, and transmit the judgment result and the tension value corresponding to the tension signal to the display screen 30 for display.

[0027] During the specific implementation, first, the bottom plate 21 is taken out of the box 10, and then the two ends of the simulation tube 40 are respectively connected to the limit members 23 to fix the simulation tube 40 above the bottom plate 21, and then the bottom plate 21 is placed in the box 10, and then the threshold is adjusted to a suitable position, and then the operator uses the simulated operating lever to perform ligation and suturing training. At this time, the tension sensing member 22 monitors the tension signal of the simulation tube 40 in real time, and transmits the tension signal to the control module 24. The control module 24 transmits the pressure value corresponding to the tension signal to the display screen 30 for display. At the same time, the control module 24 is used to determine whether the tension signal exceeds the threshold. If too much force is applied during the operation, and the tension signal exceeds the threshold, the control module 24 sends a warning signal to the display screen 30. It can be seen that by monitoring the tension signal of the simulation tube 40 in real time through the tension sensing member 22, the specific force of the trainee during the operation can be known in real time, and the trainee can be warned by setting the threshold, thereby improving the training effect.

[0028] Optionally, the tension sensing member 22 may be a tension sensor or a pressure sensor. In this embodiment, the tension sensing member 22 is a tension sensor, the model of the tension sensor is JZHL-L1, and the control module 24 is a Siemens PLC controller.

[0029] See also Figures 3 to 7As shown, specifically, the limiting member 23 includes a shell 231, the interior of the shell 231 is provided with a limiting cavity 232, and the limiting cavity 232 passes through one end and one side of the shell 231, and a rotating plate 233 is provided on the side of the shell 231 passed through, and a limiting strip 234 is provided at the bottom of the rotating plate 233, and the rotating plate 233 can be rotatably set in the shell 231 so that the limiting strip 234 is in the limiting cavity 232 or in the limiting cavity 232. When the limiting strip 234 is in the limiting cavity 232, the simulation tube 40 placed in the limiting cavity 232 is limited.

[0030] More specifically, one side of the housing 231 is provided with an elastic telescopic member 25, and the elastic telescopic member 25 is used to limit the rotation plate 233 so that the limiting strip 234 is limited in the limiting cavity 232. The elastic telescopic member 25 includes a groove 251 opened on the housing 231, and a movable plate 253 connected to the groove 251 through a spring 252.

[0031] When the simulation tube 40 needs to be installed, the operator first retracts the elastic telescopic member 25 to lose the limiting effect on the rotating plate 233, and then rotates the rotating plate 233 to make the limiting strip 234 connected to the rotating plate 233 leave the limiting cavity 232, and then inserts one end of the simulation tube 40 into the limiting cavity 232 through the end penetrated by the shell 231, and then rotates the rotating plate 233 in the opposite direction to make the limiting strip 234 connected to the rotating plate 233 enter the limiting cavity 232 to squeeze the simulation tube 40, and then stops squeezing the elastic telescopic member 25 to make the elastic telescopic member 25 block the rotating plate 233 to prevent The rotating plate 233 rotates, thereby limiting the simulated tube 40 in the limiting cavity 232, and the installation of the simulated tube 40 is completed. When the simulated tube 40 needs to be replaced, the operator contracts the elastic telescopic part 25 to lose the limiting effect on the rotating plate 233, and then rotates the rotating plate 233 to make the limiting strip 234 connected to the rotating plate 233 leave the limiting cavity 232. At this time, the limiting strip 234 pushes the simulated tube 40 outward during the movement, which facilitates the disassembly of the simulated tube 40. It can be seen that the simulated tube 40 can be limited by rotating the rotating plate 233, which is simpler to operate than the existing method of extrusion through bolts.

[0032] Furthermore, the top of the box body 10 is covered with a cover plate 11 .

[0033] Furthermore, a slide groove 12 is provided on the side wall of the box body 10 , a slider 13 is provided in the slide groove 12 , the slider 13 is connected to the bottom plate 21 , and the slide groove 12 passes through the top of the box body 10 so that the slider 13 can move in the slide groove 12 .

[0034] Furthermore, the display screen 30 includes a real-time display area, a preset display area 32, an indicator light area 33 and a photographing area 34; the preset display area 32 is used to display the tension of the simulation tube 40 in the non-operation state, the real-time display area is used to display the tension of the simulation tube 40 in real time during the operation, the indicator light area 33 is used to prompt when the tension signal exceeds the threshold, and the photographing area 34 is used to display the picture in the box 10 in real time.

[0036] In summary, the laparoscopic vascular ligation and suturing training device in the above-mentioned embodiment of the utility model first takes the bottom plate 21 out of the box 10, and then connects the two ends of the simulation tube 40 to the limiter 23 respectively, so that the simulation tube 40 is fixed above the bottom plate 21, and then the bottom plate 21 is placed in the box 10, and then the threshold is adjusted to a suitable position, and then the operator uses the simulated operating lever to perform ligation and suturing training. At this time, the tension sensing member 22 monitors the tension signal of the simulation tube 40 in real time, and transmits the tension signal to the control module 24, and the control module 24 transmits the pressure value corresponding to the tension signal to the display screen 30 for display. At the same time, the control module 24 is used to determine whether the tension signal exceeds the threshold. If too much force is applied during the operation, the tension signal exceeds the threshold at this time, and the control module 24 sends a warning signal to the display screen 30. It can be seen that the tension sensing member 22 monitors the tension signal of the simulation tube 40 in real time, and the specific force of the trainee during the operation can be known in real time, and the threshold setting can be used to warn the trainee, thereby improving the training effect.
