Description

A basic operation trainer for laparoscopy and open surgery

technical field

The utility model relates to a training device, in particular to a basic operation training device for laparoscopy and open surgery.

Background technique

The basic operation of surgery is a solid foundation for entering the clinical study of surgery and a necessary condition for completing the operation. It mainly includes disinfection, sterility, incision, hemostasis, ligation, suture, separation, exposure, etc. These are the key contents of surgical learning, among which incision, hemostasis, ligation, and suture are the most important basic operating techniques. The focus of students' ability training in the basic teaching of surgery. It is very important for future clinical practice to strictly regulate the operation, train basic operation techniques, help students lay a good surgical foundation, and cultivate solid basic surgical skills.

However, the relationship between doctors and patients is tense today, patients are rarely allowed to practice operations, and it is difficult for students to get opportunities for surgical operations, so in vitro simulation training is urgently needed.

Operations such as incision, separation, suture, and knotting are the basic skills of clinicians, and both open surgery and laparoscopic surgery need to be mastered. At present, minimally invasive medical methods such as laparoscopy are also one of the development directions of medicine, and many township hospitals have also carried out laparoscopic surgery. However, some medical schools with insufficient conditions still only allow students to practice open surgery operations, failing to keep pace with the times, which affects the training quality of medical students.

Laparoscopic surgery has made continuous progress in our country for more than ten years, and has become increasingly popular among doctors and patients, and has also created a group of laparoscopic doctors. At present, some domestic medical institutions have set up laparoscopic surgery training centers one after another and use laparoscopic simulation training devices for training. However, compared with developed countries and regions, a considerable number of laparoscopy physicians in my country still lack standardized technical training, and the matching technical preparations The entry system also needs to be established. This situation not only affects the quality of laparoscopic surgery in my country. At the same time, it also restricts the popularization and development of laparoscopic technology.

Because the laparoscopic equipment system is fine and expensive, it is very difficult for general physicians to train on laparoscopic equipment.

In the utility model, the operating cylinder 11 is fixed on the rear side of the casing 1, and its upper end is higher than the casing 1 top. In the utility model, the rear side of the box body 1 is provided with a cover that can cover the placement square hole 8 , and the cover can be opened and closed relative to the placement square hole 8 .

The support card hole 7 is provided with a support card, and the simulated surgical equipment can be pliers scissors or separating forceps or a needle holder. After the position, the simulated surgical instrument 4 will be connected to the toca hole 7 through the toca. The structural relationship between the toca hole and the toca is the same as the structure of the corresponding part in the actual operation, and is a structure well known to those skilled in the art.

The utility model is a simple integrated structure. The image information captured by the camera is displayed through a tablet computer or a monitor, and the operator faces the enlarged image of the tablet computer or display screen for operation training. The simulator consists of a zoom camera integrated machine, a tablet Composition of computer or monitor, surgical instruments, models, etc.

The top of the utility model is provided with a circular hole deep knotter, a square suture box (practice cutting, suturing, knotting, etc.), a circular hole 7 for placing the camera to connect with the tablet computer, that is, the camera passes through the The line passing through the circular hole 7 is connected to the tablet computer, and the camera is a suction cup camera, whose position in the box can be changed according to the specific situation; 2 columns are designed on the top, connected with a rubber tube, which can be used for knotting practice or The backrest of the tablet computer; the front is a character shape composed of three toca holes for putting in laparoscopic operating instruments; the back is a movable square hole, which can be put into the simulated organ to be simulated, and a hook is attached inside the box , hook up the clip, clamp the organ to be operated, etc.

It is required not to collide with the surroundings at will during the operation, and try to be as stable, accurate, light and fast as possible.

Orientation adaptation training: put foam boards in the training box, press needles or nails on the foam boards, wrap rubber bands around the needles purposefully with grasping pliers, or complete similar operations with silk threads; practice repeatedly, constantly Improve the orientation ability of laparoscopic operation.

Tissue separation training: Put bananas, grapes, oranges or chicken with skin in the training box, and use grasping forceps, scissors, separation forceps and other instruments for blunt and sharp separation training.

Suture knotting training: fix the washed animal tissue on the foam board in the box, and use the finger needle holder and separation forceps for suture knotting training; use the needle holder inside and outside the training to select the correct needle insertion position, and train the needle holder Knot method, training internal and external suturing skills.

Although this manual uses a lot of box body 1, camera 2, display 3, imitation surgical instrument 4, suture box 5, round hole purse suture knotter 6, round hole 7, placing square hole 8, hook 9, clip 10.
