Training Method of Laparoscopic Trainer
At present, the more popular standardized training methods for beginners usually include the following 5
To evaluate beginners by the time they successfully completed the task.
Checkerboard drill: mark numbers and
The trainees are required to pick up the corresponding numbers and letters with equipment and put them on the chessboard
Location to be marked. It mainly cultivates the sense of direction under two-dimensional vision and the control of the hand on the operating pliers.
Bean drop drill: mainly training the operator's hand eye coordination ability.
The operator holds the camera with one hand and picks up the beans with the other hand and moves them 15cm
Put into a container with an opening of 1 cm.
Running string drill: mainly used to train the operator's hands
Adjustment ability. Simulate the process of holding and moving the instrument to check the small intestine under laparoscopy.
The trainee holds a section of line with both hands and instruments, and starts the line from one end to the next through coordinated movement of both hands
Gradually move to the other end.
The block move drill: used to train the fine movements of hands.
There is a metal ring on the triangular wooden block. When training, first use pliers to hold a curved needle and then pass through it
Hook the metal ring and lift it to the specified position.
Suture foam drill: the trainer is required to hold two needles
Block foam materials shall be sewn together and square knots shall be made in the box. This is considered the most common laparoscopic procedure
One of the difficult skills to master.
Simple surgical training model
The above training courses only trained the operators in some basic laparoscopic techniques
Not the whole procedure. In order to make the operation under the simulator closer to the actual clinical operation,
There are also various surgical training models made of materials abroad, such as inguinal hernia repair model
Cholecystectomy model, choledochotomy model, appendectomy model, etc. These models are
The actual operation conditions are partly simulated, and the operator can complete the corresponding operation on these models,
Through training on these models, trainees can quickly adapt to and master these operations.
Training method of living animal model
That is to say, animals are used as training objects for laparoscopic operation. Initial development of laparoscopic technique
This mode is often adopted in the future. Living animals provide surgeons with the most realistic operating environment
Such as normal tissue reaction during operation, injury and bleeding of surrounding tissues and organs when the operation is improper
Even the death of animals. In this process, the surgeon can be familiar with the design of laparoscopic surgery
Composition, function and application of equipment, instrument, laparoscope system and supporting equipment. Be familiar with establishing pneumoperitoneum
The method of placing the cannula. After the operation, the abdominal cavity can be opened to check the completion of the operation and whether there is any
Peripheral organ damage. At this stage, trainees are required to master the actual operation of laparoscopic surgery
In addition to the relevant operation methods, attention should also be paid to the cooperation between the operator and the assistant, the lens holder and the instrument nurse.
The main disadvantage is that the training cost is too high.
Laparoscopic clinical skills training
After simulation training, students can step by step after mastering basic laparoscopic operation skills
To the clinic. The process usually includes three stages: first, on-site surgical observation
The stage enables students to become more familiar with various laparoscopic equipment and instruments, and
The teacher explains the operation steps and key points, so that students can further understand and feel
The whole process of laparoscopic surgery. The second stage is to act as an operative assistant in laparoscopic cholecystectomy
Or when appendectomy is relatively simple, let him act as the mirror hand, and then act as the first
Assistant. Each operation of the operator should be carefully observed and pondered
To master the operation technique of laparoscope. The third stage is to act as an operator under the guidance of teachers,
Complete laparoscopic appendectomy, cholecystectomy and other operations. At the beginning, the instructor can
The non critical or relatively simple operations of the
Evaluation, and then gradually transition to completion by students according to their mastery of laparoscopic technology
The whole operation. In this process, students should constantly summarize experience and pay attention to their own
Strengthened training on weaknesses and deficiencies, and constantly improved laparoscopic operation skills during surgery,
After a long and hard training, he gradually became a qualified clinical laparoscopic surgeon.
The Necessity of Laparoscopic Basic Skills Training
As laparoscopy is a new technology, it is also open to the traditional surgery technology.
The operation is completely different. During laparoscopic surgery, the operator faces a two-dimensional monitor to complete three-dimensional space
The beginner will not adapt to the displayed image, and the judgment will be inaccurate
The action is uncoordinated and the equipment does not obey the command. This hand eye coordination required for laparoscopic surgery
The ability to adjust and perceive three-dimensional space must be gradually adapted through long training
Improve. In addition, during laparoscopic surgery, the surgeon in charge completes most of the operations
For the assistant, there is not much opportunity to perform the operation, while laparoscopic surgery requires three-dimensional space
The perception of depth, size, direction and level can only be experienced by the operator.
Therefore, it is very necessary to train beginners in basic skills.
