RU2370221C1 - Training simulator for mastering technical skills of tendon suture - Google Patents

Abstract

FIELD: medicine.

SUBSTANCE: invention relates to medicine and can be applied for practical training of doctors traumatologists, surgeons various technical skills of applying tendon sutures. Training simulator for mastering technical skills of tendon suture consists of supporting platform, made from wooden plate and includes two hollow plastic cylinders fixed on supporting platform. On cylinder surface ellipse-shaped hole imitating operation wound is made. Foam rubber bar with transected in the centre rubber strip is inserted inside the cylinders to imitate injured tendon. Rubber strip is fixed on one of bar surfaces with possibility to turn inside out for control of thread passing, estimation of rubber edge adaptation and for estimation of strength by tension.

EFFECT: mastering various technical skills of tendon suture using device of simple construction imitating real clinical conditions.

Description

The invention relates to medicine and to the field of education, in particular to equipment for the practical training of orthopedic traumatologists, surgeons in various techniques for suturing tendons.

Mastering the tendon suture technique as part of higher education begins on the course of operative surgery, where classes are held on cadaveric material. The disadvantage of this technique is the difficulty of storing the material, limited availability during group classes, the spent material cannot be restored. These disadvantages are eliminated by using special simulators. The closest analogue (prototype) of the proposed device is a "simulator for practicing the technique of surgical operations" proposed by R. Sukhoverkhov (Sukhoverkhov R.I., Krivoshchekov E.P. Military Medical Journal. - 2001. - No. 9. - p. 70), along with the advantages (multifunctionality), which has a number of disadvantages.

The disadvantages of the prototype are:

- the presence of many functional units that impede its manufacture, as well as storage and transportation;

- rubber rods are used as a tendon, which does not properly mimic a tendon;

- dummies of tendons are located on the plates, which does not provide real clinical conditions: lack of imitation of a wound, damaged segment.

The objective of the invention is to create a device that allows you to master the seam of the tendon, devoid of these disadvantages.

The technical result is the mastery of various methods of tendon suture using a device of simple design, more simulating real clinical conditions.

The solution to this problem and the achievement of a technical result provides a simulator for mastering the tendon suture technique (see drawing).

The proposed simulator consists of a support platform, its size is 120 × 100 mm, made of wood slab 1, two hollow plastic cylinders 2 with a volume of 10 ml. Cylinders with two fasteners 3 are fixed to the support platform. On the surface of the cylinders, facing upwards, simulating an operative wound, an ellipsoidal hole 4 is applied. Inside the cylinders, a foam rubber block 70 * 15 mm in size is inserted. A strip of knitted rubber 5 50 mm long is fixed along the length of the bar with the help of seams on one of the surfaces, in the middle of the strip of knitted rubber it intersects, imitating a damaged tendon. For greater stability of the bar in the cylinder, the latter is closed with a plug made of a piston for a disposable syringe 6.

In the process, the device is used as follows: With the help of appropriate surgical instruments and suture material, one or another type of tendon suture is performed, after the suture is completed, the rubber strip is turned out and the thread is controlled, the strength of the suture by stretching is evaluated, the edges of the rubber are adapted. To continue the activity, the foam rubber block with a strip of knitted rubber changes.

The proposed simulator for the development of tendon suture technique has the following advantages:

- the use of cylinders with an elliptical hole, strips of knitted rubber allows you to simulate conditions close to the conditions of the surgical wound;

- the constructive simplicity of manufacturing a simulator for the development of a tendon suture does not require complex, expensive materials;

- the low cost of consumables allows you to reuse the simulator without significant economic costs;

- small size, ease of transportation, no need for special storage conditions;

- the possibility of using for training the tendon suture technique as a group of students in the classroom, and by doctors of surgical hospitals in hospitals.

Claims (1)
