Description

Intelligent training method and system for simulating abdominal cavity lavage

Technical Field

The invention relates to a medical teaching training system, in particular to an intelligent training method and system for simulating peritoneal lavage.

Background

The peritoneal lavage and drainage is also called therapeutic continuous peritoneal lavage and drainage, which is developed from pure normal saline lavage to target lavage liquid with antibiotics, trace heparin, chymotrypsin, etc. The data show that: the method can be used for treating pyorrhea, hydrops, severe peritonitis, complicated abdominal wound or leakage. The peritoneum has a great capacity for the removal of water molecules, but is slow for the removal of cellular molecules and microorganisms. If a large amount of toxins and bacteria are not cleared in time, serious circulatory failure and death can be caused after absorption. Postoperative antibiotic therapy is also sometimes difficult to work with. The purpose of adopting the peritoneal lavage for drainage is to effectively dilute toxin and reduce the concentration of bacteria so as to be beneficial to the exertion of the defense mechanism of the organism; the optimal concentration of the antibiotic in the abdominal cavity can be maintained by adopting internal antibiotic treatment; foreign matters which are difficult to absorb by the peritoneum can be removed through lavage and drainage, and quadrant abscesses of the small septal sample of the small chamber can be damaged; peritoneal lavage and drainage and has a peritoneal dialysis effect like that of the treatment of uremic patients, by which most toxins and bacteria can be dialyzed out. Can also be used for maintaining normal serum biochemistry or correcting metabolic disorder by adjusting ion concentration and osmotic pressure of lavage solution, and is helpful for internal environment stabilization.

In the peritoneal lavage operation, a puncture tube or puncture placing operation is needed, namely, anesthesia is firstly carried out, a puncture needle is adopted for puncture after anesthesia, a guide wire is placed through a side hole of the puncture needle after puncture, skin is dilated after the puncture needle is withdrawn, and then a catheter is sleeved in the guide wire for tube placement. However, both the placement of the guide wire and the placement of the catheter require the insertion depth, the insertion position, and the insertion speed, and the placement of the catheter also requires the manipulation. Human factors have a great influence on the operation. However, if the operation is careless and careless, serious consequences can also happen. When the abdominal cavity lavage is used for puncture and catheterization, if the guide wire or the catheter is inserted too deeply, the guide wire or the catheter is inserted into an organ, mechanical stimulation is caused to the organ, even the organ is punctured, and serious consequences are caused. If the guide wire is inserted too shallowly, the guide tube cannot be guided to be normally placed in a preset position, so that effusion cannot be extracted through the guide tube, and the peritoneal cavity cannot be irrigated.

Generally, doctors need to get experience in the process of learning and training through continuous practice and training so as to improve the medical level of the doctors. Traditional training and training for new physicians has no better training simulation means other than using cadavers and animals. The training by using animals has a plurality of defects, the anatomical structure of the animals is different from that of human bodies, particularly the depth of a guide wire to be placed and a catheter to be placed is completely different in puncture catheter placement operation, and simulation operation cannot be carried out. When a corpse is subjected to puncture tube-placing operation, the blood-back indication cannot be carried out, and abdominal cavity lavage operation exercise cannot be carried out.

The virtual operation training system is applied to modern medicine by adopting a computer, and integrates the cross fields of various subjects such as computer technology, graphic imaging, sensor technology, biomechanics, modern medicine, computer vision, robotics and the like.

At present, the abdominal cavity lavage training is mainly carried out by using a human body model, and a plurality of specifications or details can not be reflected in the process of carrying out the abdominal cavity lavage, such as operation step feedback, doctor-patient interaction, puncture angle monitoring, puncture depth, guide wire placement and tube placement detection, implantation depth detection, implantation speed detection, implantation manipulation detection, instrument selection and the like. And when local anesthesia is carried out, layer-by-layer anesthesia is needed, the process of simulating anesthesia puncture can be really simulated only by designing the simulation human body structural tissues in the human body model, lavage reflux needs to be designed, the structural simulation degree of the model is high, and the cost is very high. And no interaction exists among doctors and patients, the operation steps cannot be monitored and recorded, the operation results cannot be counted and fed back, the operation process cannot be sensed, and the like. In addition, model teaching can not give corresponding feedback to students according to different operations of the students; the teacher has to teach the skill teaching in a classroom, and the daily training is difficult to develop; the traditional way of training is only skilled practice and lacks the cultivation of clinical thinking.

And how to detect the puncture catheterization operation in the puncture catheterization training, accurately position the guide wire and the catheter, and particularly how to acquire and position in real time is the problem to be solved by operation feedback.
