Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of surgical simulation equipment, and more particularly to a simulation training device for laparoscopic surgery. Background Art
[0002] Laparoscopic surgery is a minimally invasive procedure that is now widely used. With the rapid advancement of industrial manufacturing technology and the integration of related disciplines, a solid foundation has been laid for the development of new technologies and methods. Coupled with the increasing sophistication of surgeons, many previously open surgeries have been replaced by endoscopic procedures, expanding surgical options for patients. The expensive instruments used in laparoscopic surgery make practice even more valuable. Improving laparoscopic skills through training is extremely challenging for surgical assistants, uncertified residents, and operators.
[0003] The existing Chinese invention patent CN116824941A provides a laparoscopic surgery training device including a training platform, a training simulation box, a coordination training mechanism and a movement auxiliary mechanism. The present invention provides a laparoscopic surgery training device. During laparoscopic surgery training, before laparoscopic surgery training, current is provided to the annular tube through the power supply inside the power box, so that the current can flow through the entire annular tube. The operator uses a first operating clamp to clamp the clamping plate above the detection ring, and surrounds the annular tube from the starting point to the end point to train the coordination of both hands. After the detection ring collides with the annular tube, the powder in the prompt box at the lower end of the detection ring will be shaken out from the prompt box. The shaken-out powder corresponds to the collision position, which is used to mark the collision position of the detection ring and the annular tube. In this way, the number and position of touching the tube wall are understood.
[0004] The above training device still has the following disadvantages:
[0005] 1. Recording the collision position of the detection ring and the annular tube by shaking off powder is unreliable. The amount of powder in the prompt box is fixed. When a collision occurs in the early stage, a large amount of powder will be spilled. Later, when the powder inside is less, the amount of spilled powder will gradually decrease, or even disappear, which may lead to recording errors. In addition, this method cannot intuitively observe the entire movement process, which may lead to certain deviations in the judgment of hand coordination and stability.
[0006] 2. The front end of the laparoscopic surgical manipulator is usually a functional area with blades, clamps, etc. When the manipulator drives the detection ring, if the blade or clamp collides with the energized ring tube, it is very easy to cause danger;
[0007] 3. The structural design of the simulation training device may be unreasonable, resulting in limited operating angles, restricting the freedom of training, and affecting the accuracy of operation and training effects. Summary of the Invention
[0008] The purpose of the present invention is to provide a simulation training device for laparoscopic surgery to solve the above technical problems.
[0009] The above technical objectives of the present invention are achieved through the following technical solutions: A simulation training device for laparoscopic surgery, comprising a standing platform, a support column, a surgical simulation box, an operator and a display, the display having a built-in processor, a controller, a storage, a signal receiver and a signal transmitter, the standing platform is fixedly connected to the support column, the top of the support column is fixedly connected to a balance platform, the top of the balance platform is fixedly connected to a hydraulic telescopic rod, the top of the hydraulic telescopic rod is fixedly connected to an operating table, the surgical simulation box is placed on the operating table, a connecting rod is provided at a corner of the operating table, the connecting rod is connected to the display, the top of the surgical simulation box is covered with a cortical simulation layer, and the operator simulates surgery in the surgical simulation box by inserting the cortical simulation layer.
[0010] The present invention is further configured as follows: the surgical simulation box includes an outer box and an inner box, the inner wall of the outer box is provided with an adhesive surface for attaching a simulated cyst or tumor; a serpentine obstacle column is provided in the inner box, both ends of the serpentine obstacle column are fixedly connected to a fixing seat, the bottom of the fixing seat is fixedly connected to a base, the base is fixedly connected to the inner box, a hanging rod is provided in the inner box, the hanging rod is provided on the side wall near one end of the serpentine obstacle column, a movable ring is sleeved on the serpentine obstacle column, a clamping plate is provided on the top of the movable ring, the clamping plate is sleeved with a hanging ring, and the hanging ring is hung on the hanging rod.
[0011] Using the above technical solution, the trainee stands on a stand and holds a handheld manipulator to perform surgical simulation training. During training, various modes can be set according to the different conditions of the surgical simulation box. The trainee first practices surgical incisions on the cortical simulation layer, then inserts the handheld manipulator into the incision for training. During the initial training phase, novices can release the grasping forceps with the handheld device, remove the hanging ring from the hanging rod with the grasping forceps, and move the moving ring along the serpentine obstacle column, preferably without the inside of the moving ring touching the serpentine obstacle column. Later in training, when the moving ring's trajectory has become relatively stable, cyst and tumor cutting training can begin. At this stage, the difficulty of cutting varies depending on the location of the cyst and tumor. Cysts and tumors can be placed in different locations of the outer box and cutting training can be carried out from easy to difficult according to needs. After the cutting technique training reaches the required standard, obstacles can be installed near the cyst or tumor to simulate the location of internal organs within the abdominal cavity, allowing for more difficult surgical training. During the cutting training, according to the different cutting positions, the feet need to step on the hydraulic control pedal at the same time to control the extension and retraction of the hydraulic telescopic rod, and then adjust the angle of the operating table to make cutting more convenient and train the coordination ability of hands and feet at the same time.
[0012] The present invention is further configured such that a displacement sensor is provided inside the clamping card.
[0013] By adopting the above technical solution, the displacement sensor is used to collect the movement curve of the clamped card, and the stability of the trainee using the equipment during the operation can be judged according to the trend of the movement curve.
[0014] The present invention is further configured as follows: the manipulator includes a handheld part and an operating rod, the handheld part is connected to the operating rod, a lock is provided on the handheld part, the interior of the operating rod is divided into two pipes, one of which is used to absorb waste liquid residues generated after surgery, and a moving rod is provided in the other pipe, a grasping forceps is provided at the bottom of the moving rod, the handheld part controls the extension and retraction of the moving rod and the opening and closing of the grasping forceps, the head of the operating rod is provided with an inhaler, a cutting port and a visual lens, and a cutting knife is provided at the opening of the cutting port.
[0015] By adopting the above technical solution, when the trainee operates the manipulator, he holds the handpiece and inserts the operating rod into the surgical simulation box. The visual lens captures the image in the surgical simulation box in real time and displays it on the monitor. The trainee can perform cutting training according to the image on the monitor. The handpiece is used to control the extension and retraction of the moving rod and the opening and closing of the grasping forceps. When the grasping forceps grasps the cyst or tumor to be cut, the moving rod is retracted, and the cyst or tumor is cut off by the cutting at the opening of the incision. It can then be sucked out by the suction device. The locking device is provided so that when the novice is doing the mobile ring training in the early stage and the gripping ability is not so strong, the grasping forceps can be locked by the locking device after clamping the clamping card to prevent it from slipping.
[0016] The present invention is further configured as follows: a hydraulic control pedal is provided on the standing platform, two hydraulic control pedals are distributed on each side of the left and right sides of the support column, and a total of 6 hydraulic telescopic rods are provided, with the display side as the upper, 1 each on the upper and lower sides, and 2 each on the left and right sides. The hydraulic telescopic rods on the upper and lower sides control the forward and backward tilt of the operating table, and the hydraulic telescopic rods on the left and right sides control the left and right tilt of the operating table. The four hydraulic control pedals respectively control the extension and retraction of the upper hydraulic telescopic rod, the lower hydraulic telescopic rod, the left hydraulic telescopic rod and the right hydraulic telescopic rod.
[0017] The present invention is further configured such that a balance sensor and an angle offset sensor are provided in the operating table.
[0018] By adopting the above technical solution, the balance sensor box angle offset sensor is used to collect the balance and tilt angle of the operating table. According to the changes in the balance and tilt angle of the operating table, feedback can be provided on the coordination ability of the hands and feet of the person using this equipment, as well as the ability to control the tilt of the operating table.
[0019] The present invention is further configured as follows: an anti-slip area is provided at the center of the operating table, and anti-slip particles are provided at the bottom of the surgical simulation box.
[0020] By adopting the above technical solution, when adjusting the tilt angle of the operating table, with the anti-slip area and anti-slip particles, displacement between the surgical simulation box and the operating table can be better avoided.
[0021] The present invention further provides a system for the above-mentioned simulation training device, the system comprising:
[0022] Central module: The central module includes a processor, a controller and a memory;
[0023] Signal transmission module: The signal transmission module includes a signal receiver and a signal transmitter;
[0024] Signal acquisition module: The signal acquisition module includes a visual lens, a displacement sensor, a balance sensor and an angle offset sensor;

The printer prints the relevant information of the surgical simulation process after the simulation is completed. The mobile device receives the relevant information of the surgical simulation process after the simulation is completed.
[0030] In summary, the present invention has the following beneficial effects:
[0031] The training equipment of the present invention is divided into the following training stages:
[0032] Phase 1: The handheld operator controls the gripper to clamp the card, remove the hanging ring from the hanging rod, press the lock, and control the moving ring to move on the serpentine obstacle column;
[0033] Phase 2: Based on the first phase, the lock is no longer used, and the trainee can move the moving ring by holding the card by himself;
[0034] Phase 3: Place materials simulating cysts or tumors at different locations on the outer box for cutting training;
[0035] Phase 4: Based on the third phase, a simulated cyst or tumor is installed in a position where cutting is more difficult. By controlling the hydraulic control pedal, the hydraulic telescopic rod is driven to move, and then the operating table is tilted to assist in better cutting training and at the same time do hand-foot coordination training.
[0036] The present invention is based on the above four stages of training, which basically covers all stages of laparoscopic surgery training. The first and second stages mainly train the stability of the hands, the third stage performs surgical cutting training, and the fourth stage further performs coordination training of the hands and feet on the basis of the above, meeting the needs of trainees at each stage. The staged training mode can provide positive or negative feedback to the trainees in stages, so that they can adjust the deficiencies in the training in real time, and avoid the occurrence of a large number of problems during the training process that cause them to lose confidence and find no solutions. At the same time, compared with the existing technology, because its angle is adjustable, it can effectively improve the accuracy and effect of training, and will not be limited by the operating angle, affecting the freedom of training.

DETAILED DESCRIPTION

[0048] Example 1: The trainee stands on a standing platform 7 and holds the manipulator 4 to perform surgical simulation training. During training, multiple modes can be set according to different situations of the surgical simulation box 2. The trainee first makes a surgical incision training on the cortical simulation layer, and then inserts the handheld manipulator 4 into the incision to continue training.
[0049] During the first training phase, the trainee can release the gripper 405 through the handheld portion 401, and use the gripper 405 to clamp the clamping plate 209 and remove the hanging ring 204 from the hanging rod 208. At this time, press the lock 402, and the gripper 405 will firmly clamp the clamping plate 209. The trainee only needs to operate the operator 4 to drive the mobile ring 207 to move on the serpentine obstacle column 203. It is best to ensure that the inside of the mobile ring 207 does not touch the serpentine obstacle column 203. After reaching the other end of the serpentine obstacle column 203, replace the operator 4 on the other side and do the same training again to train the stability of the left and right hands. After completing a round-trip training, by checking the trend of the displacement sensor 16, the offset of the mobile ring 207 can be observed so that corresponding adjustments can be made during the next training. When the smoothness of the movement curve of the displacement sensor 16 reaches a certain level, the next phase of training can be carried out.
[0050] Example 2: Based on Example 1, after clamping the clamping card 209, the lock 402 is no longer used. The trainee controls the handheld part 401 to clamp the clamping card 209 and drives the moving ring 207 to move back and forth on the serpentine obstacle column 203. When the smoothness of the moving curve of the displacement sensor 16 reaches a certain level, the next stage of training can be carried out.
[0051] Example 3: After the movement trajectory of the displacement sensor 16 has become relatively stable, cyst and tumor cutting training can begin. At this stage, the difficulty of cutting varies depending on the location of the cyst or tumor. As needed, cysts and tumors are placed in different locations of the outer box 201 for cutting training, from easy to difficult. After the cutting technique training reaches the corresponding standard, obstacles can be installed near the cyst or tumor to simulate the location of internal organs in the abdominal cavity, allowing for more difficult surgical training.
[0052] Example 4: Based on Example 3, during the cutting training process, according to the different cutting positions, the foot needs to step on the hydraulic control pedal 6 at the same time to control the extension and retraction of the hydraulic telescopic rod 10, and then adjust the angle of the operating table 5, making cutting more convenient and training the coordination ability of hands and feet at the same time.
