Description

Laparoscopic surgery simulation training system

Technical Field

The utility model relates to an endoscopic surgery simulation training system, in particular to a laparoscopic surgery simulation training system.

Background

Since minimally invasive surgery has the characteristics of less trauma, less bleeding and rapid recovery, it is accepted and liked by patients, and thus more and more surgical operations are performed laparoscopically. However, the quick recovery of the laparoscopic minimally invasive surgery is based on the laparoscopic surgery technology mastered by the operating physician, the speed of the surgery completion time and the amount of bleeding during the surgery directly influence the recovery speed of the patient after the surgery, so how to improve the laparoscopic technology has a very important significance for improving the application safety and the efficiency of the laparoscopic minimally invasive surgery and the quick recovery of the patient after the surgery. In order to improve the laparoscopic surgery technique, it is necessary to continuously simulate and practice the operations and steps in the surgery on the laparoscopic trainer, and train the remedial measures of the sudden complications encountered in the surgery, such as blood vessel bleeding, organ injury, etc., so as to improve the mastering of the operator on the surgery technique and improve the surgery efficiency. There is therefore a need for a laparoscopic surgery simulation training system to improve the surgical skill of the surgeon.

In the prior art, there are simple devices that attempt to achieve this goal. For example, a "training simulator for laparoscopic surgery" disclosed in CN200979766Y, an "training instrument for endoscopic surgery" disclosed in CN101589416A, a "training simulator for laparoscopic surgery" disclosed in CN205862635U, and a "training simulation box for surgery" disclosed in CN 207742836U. The above-mentioned technique is all surrounded by the plate and forms closed or semi-closed box simulation human abdominal cavity, and the trompil makes surgical equipment can pass on the box, sets up the camera stick in the video acquisition equipment simulation operation or utilizes the trompil on the box directly to use the camera stick in the operation on the box or in the box, places simple model in the box and supplies the training person to practise. Such as placing a piece of pigskin to train the suturing technique.

It can be seen that these simple surgical simulation training devices are simple models, which can only practice the most basic operations and manipulations, and cannot simulate the bleeding of the surgical area and the specific appearance of organ injury which may occur in the real surgery, and cannot achieve the training and improve the ability and technique of handling the emergency in the surgery of the operator. Therefore, there is a need to develop a laparoscopic trainer that can simulate the common complications that actually occur during surgery, and improve the strain capacity of the operator during surgery.

The Chinese patent CN103886797A discloses a highly simulated laparoscopic surgery simulation trainer and the CN103886798A discloses a highly simulated interventional surgery trainer, which are improved aiming at the model in the prior art, and provide a human organ model surgery training device with high simulation degree. However, the above-described improvement techniques are bulky as a whole. Secondly, animal organs are put into the simulated human body model, and the animal organs are required to be connected with a circulating pipeline system. The method for obtaining the animal viscera has the advantages of limited obtaining ways and obtaining quantity, extremely high possibility of putrefaction of the animal viscera and difficult preservation, and the connection of the animal viscera and a pipeline system is technically very difficult to realize, so that the cost is high even if the connection can be realized. The circulating pipeline system for simulating the human body circulating system has no practical significance in operation practice, and the pressure in the circulating pipeline is not easy to approach and keep at the pressure of the real human body circulating system. In addition, the pump and the collecting tank adopted in the improved technology as the circulating pipeline system are large in size, and special electric power is needed for working and driving when the improved technology is used. The improved technology only remains in theory, is not as good as directly practicing on the animal body in actual operation, and has no value of popularization and application in reality.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a laparoscopic surgery simulation training system has solved the common complication that current training system can not simulate to appear in the operation, can't train the operator in the operation strain capacity, and can only follow the problem that fixed angle carries out the operation of different operations.

In order to solve the technical problem, the utility model provides a following technical scheme:

a laparoscopic surgery simulated training system comprising:

a box body for performing operation training operation;

the organ model is placed in the box body, a pipeline for simulating a human body fluid system is arranged in the organ model, one end of the pipeline, which is positioned in the organ model, is in a closed state, and the pipeline is provided with an interface outside the organ model;

the pressure water bags are provided with water conveying pipes, outlets of the water conveying pipes are mutually connected and communicated with corresponding interfaces of the organ models, and the pressure water bags are provided with pre-pressure adjusting structures.

Because the operation simulation training only aims at a single organ, and rarely has the operation simulation training of multiple organs, the existing training box or similar training boxes are enough to be utilized, and the simulation of the whole human environment is not needed. In a general normal operation, when a tube needs to be cut, the tube in the direction of both sides of the incision or the tube in the direction of the side into which the body fluid at the incision is transferred needs to be ligated, and the tube can be cut after the ligation is completed, and the tube is not cut in an open state and the incision is exposed to the air. Therefore, the completion degree of the ligation of the pipeline can be checked by keeping the pipeline simulating the human body fluid system at a proper pressure. The closed pipeline can well maintain the pressure in the pipeline. The liquid in the pipeline is in a real flowing state, so that the pressure in the pipeline is difficult to maintain, and the whole operation simulation training is not influenced. In a successful operation simulation training, the liquid in the pressure water bag can not be consumed at all, and the pressure water bag can be completely reused, so that the consumption of materials can be saved to the maximum extent, and the structure is simpler and more reasonable. Once the operation is wrong or fails, the liquid flows out, due to the existence of the pressure in the pipelines, the liquid with different pressures flows out from different pipelines, if the liquid is dyed, the colors of the liquid in different pipelines are different, and if the color of the real body fluid corresponding to the human body is simulated for dyeing, the simulated degree is closer to the real operation state compared with any prior art. The trainer should judge the simulated body fluid according to the state of the outflow fluid and decide the remedial measures according to the judgment. Even with the training system, the practitioner can perform an operation simulation training for emergency remedy in a state where the liquid flows out from the intentionally set region. Meanwhile, when liquid flows out, the loss of the liquid can be obtained according to the residual quantity of the liquid in the pressure water bag, so that a quantitative evaluation index is provided for the result of the simulation training.

Furthermore, the pre-pressure adjusting structure comprises a water bag chamber for accommodating the pressure water bag, an extrusion part is arranged in the water bag chamber, the extrusion part has a pre-pressure which is adjustable, and the pre-pressure makes the extrusion part tend to reduce the space of the water bag chamber.

Furthermore, a ruler is arranged between the back plate and the extrusion plate.

Because the pressure of the backboard is determined by the compression degree of the compression spring, the pressure applied to the backboard can be marked by the distance between the backboard and the extrusion plate, so that the prepressing force of the backboard on the pressure water bag can be accurately set by adjusting the adjusting bolt and observing the scale.

Furthermore, the water bag cabin is detachably connected with the box body.

Furthermore, the box body comprises a bottom plate and a cover shell detachably connected to the bottom plate through a plurality of locking assemblies, wherein a plurality of operation holes are formed in the cover shell, each locking assembly comprises a female buckle pivoted to the cover shell and a male buckle fixedly arranged on the bottom plate, a driving assembly is arranged in each male buckle, and the driving assembly is used for enabling the female buckle to be separated from each male buckle.

because the focus body can be detachably connected with the organ body, corresponding focus models can be added according to different focuses of different diseases, and focus positioning and resection operations in the operation process can be trained;

because the pressure of the pressure water bag can be adjusted to the real pressure corresponding to the simulated blood vessel, the bleeding amount and the bleeding speed in the operation can be simulated;

because the color of the liquid in different pipelines is different, the trainer can judge which simulated body fluid is according to the state of the flowing liquid and decide which remedial measure is adopted according to the judgment, and the operation state is closer to the real operation state.

Because the housing is detachably connected to the bottom plate through the locking assembly, and the operation hole is positioned on the housing, different housings can be replaced according to different organ models because the positions and sizes of the operation holes required by different operations are different, and the locking state of the housing is stable and reliable.
