Description

A deep no-stretch knotting training device

technical field

The utility model relates to a medical teaching instrument, in particular to a surgical knot-tying training device without pulling.

Background technique

Knot tying is a very important technique in surgical operations. Suturing in surgery is inseparable from ligation. It can be said that it runs through the process of surgical operations and is one of the most basic operations. However, low-quality knotting may be pulled to other physiological tissues, especially in fine surgery and vascular surgery, which can lead to unstable and unreliable ligation, slipping and loosening of knots after surgery, causing bleeding, secondary infection and digestive juices Leakage may even endanger the life of the patient. In the prior art, such as Chinese Patent No. 200820142201.5 utility model patent, the disclosure date is August 5, 2009, which discloses a knotting training model, which mainly consists of a base, a set of magnetic structures, and three specifications of transparent The cylindrical cavity structure is composed of two parallel simulated blood vessels. The bottom surface of the base is equipped with an adsorption plate for fixing the model. It is composed of a magnetic structure, one is installed on the base, and the other is installed on a ring. A module, which is adsorbed on the magnetic poles on the base. The magnetic structure is used to simulate the mutual pulling force and traction force between tissues. The cylindrical cavity structure simulates the space in the human abdominal cavity with different sizes and depths. Two simulated blood vessels are composed of a cavity soft tube made. Although the above-mentioned technical scheme can enable learners to repeatedly practice various knotting operations, it has the disadvantages of complex structure, high manufacturing cost, and lack of feedback information.

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiencies of the above-mentioned prior art. The utility model also provides a no-stretch knotting training that can accurately judge the training effect and is easy to operate.

The technical problem to be solved in the utility model is solved through the following technical solutions:

A deep no-stretch knotting training device, comprising a base, a hollow barrel arranged on the base, and a simulated blood vessel passing through the hollow barrel, the simulated blood vessel has tension, and also includes a tension detector, the A tension detector is connected with the simulated blood vessel.

According to the utility model, a deep no-stretch knotting training device also has the following subsidiary technical features:

An alarm is also set on the tension detector.

It also includes a liquid supply device, and the liquid supply device communicates with the simulated blood vessel.

The simulated blood vessel is a hollow latex tube or rubber tube.

The hollow barrel is a transparent plastic barrel.

Compared with the prior art, the non-stretch knotting training device provided by the utility model has the following advantages: the utility model is provided with an alarm device, which will alarm when pulled to a certain extent, can accurately judge the training effect, and has good controllability. Strong, rich feedback information, etc., can cultivate students' ability to carry out comprehensive non-stretch knotting training.

Detailed ways

Referring to Fig. 1 , a deep no-stretch knotting training device provided in the utility model includes a base 1, a hollow barrel 2 arranged on the base 1 and a simulated blood vessel 3 passing through the hollow barrel 2, The simulated blood vessel 3 has tension, and also includes a tension detector 4, the tension detector 4 is connected with the simulated blood vessel 3, and the tension detector 4 is also provided with an alarm 5, when pulling a knot , the tension detector 4 detects the tension of the simulated blood vessel 3, and if the tension is greater than the limit value of the tension detector 4, the alarm device 5 will alarm, so as to objectively feed back the result of the practitioner's knot-tying training.

Referring to Fig. 1, according to the above-mentioned embodiment provided by the utility model, it also includes a liquid supply device 6, the liquid supply device 6 is connected with the simulated blood vessel 3, and the switch of the liquid supply device 6 is opened after the knotting is completed. , by observing the leakage of the liquid in the simulated blood vessel 3 to evaluate the operator's knot-tying quality. If there is liquid outflow in the simulated blood vessel 3, then the knotting quality is poor.

Referring to Fig. 1, according to the above-mentioned embodiment provided by the utility model, the simulated blood vessel 3 is a hollow latex tube or a rubber tube, and the utility model utilizes the characteristics of elasticity and tension of the latex tube or the rubber tube to simulate the bending of the human blood vessel , Extensibility. And the liquid simulating human blood is housed in the hollow latex tube or the rubber tube. Thereby the simulation of the utility model is enhanced.

Referring to Fig. 1, according to the above embodiment provided by the utility model, the hollow barrel 3 is a transparent plastic barrel, and the above-mentioned structure can clearly see the knotting operation steps of the students by observing the transparent plastic barrel.
