Description

Ultrasonic guiding positioning adjusting device for accurately injuring tissues in animal body

Technical Field

The utility model relates to an animal causes experimental apparatus technical field that hinders, concretely relates to accurate supersound guide positioning adjusting device that causes the injury of tissue in animal body.

Background

When the on-site hemostasis or injured channel repair of fire ware penetrating injury or blind channel injury is researched, a ballistic gun is often used for accurately injuring specific tissues in an animal body, such as organs or blood vessels, and simulating the injuring effect of specific parts of the human body under a battlefield or anti-terrorism condition, and a standardized animal injuring model is established and used as a basis for structural design and effect evaluation of a hemostasis material and a hemostasis device.

In order to establish a precise and injury-causing standardized animal model, the flight path of a bullet shot by a ballistic gun has good repeatability, in an injury experiment, a specially-made ballistic gun is usually selected for injury, the bore of the gun is designed by a special rifling, and the bullet shooting precision and the repeatability are good. The bullet gun body is firmly fixed on the large-mass adjustable base, the shooting angle and the height of the bullet trajectory line can be slightly adjusted, and the gun body cannot be displaced after multiple times of shooting. Within the shooting range of 15-20m, the deviation absolute error of the ballistic gun is less than or equal to +/-5 mm, and the repeatability absolute error is less than or equal to +/-5 mm.

When the outer surface of an experimental animal is injured, the shooting accuracy and repeatability of the ballistic gun are good, in order to establish a standardized animal injury model and realize accurate injury positioning of a bullet, the experimental animal is usually supported or suspended and fixed on a platform, and then the injury simulating position of the experimental animal is adjusted to a bullet trajectory line. Under the influence of gravity acceleration, the free flight path of the shot is parabolic. Considering that the bullet flight speed is high (700-. If the injury distance is selected to be 15m, namely the animal to be injured is placed at the position of 15m, the first positioning target 101 and the second positioning target 102 can be respectively placed at the positions of 16m and 17m, the first positioning target 101 and the second positioning target 102 are hollow positioning target frames and are pasted with target paper, the position of the ballistic gun 103 is adjusted to be horizontal and then shooting is carried out, two bullet holes 104 are formed in the surface of the target paper, and the connecting line of the centers of the two bullet holes is the bullet shooting track 105. The bullet firing trajectory 105 is formed as shown in fig. 1.

However, when the tissue in the animal body is injured, the tissue cannot be seen in the animal body, and the relative position of the tissue is indirectly displayed through auxiliary equipment, so that accurate injury can be realized.

Tissue injury experiments in experimental animals generally utilize imaging devices such as ultrasound, X-ray, etc. to visualize the tissue and trace transverse and longitudinal intersecting incisions 106 on the surface of the experimental animal to mark the impact point and the bullet shooting trajectory, as shown in fig. 2.

Through analysis, the positioning error is mainly caused by the following factors:

(1) according to the marking method of the cross-cut line, it is difficult to accurately determine the bullet incidence angle.

The distance between the tissue to be wounded in the experimental animal body and the epidermis is a certain distance, even if the bullet impact point can be ensured to have good repeatability on the body surface of the experimental animal, the bullet impact point is gradually increased along with the increase of the incident depth, and the deviation of the incident angle inevitably causes the trajectory of the bullet to deviate from the tissue to be wounded more and more. For example, at a lesion depth of 100mm, a deviation of 10 ° from the incident angle will cause the bullet to deviate 17mm from the intended trajectory, and if a tiny tissue (only 5-10mm in diameter) such as an arterial vessel 107 is injured, the bullet will deviate from the lesion-causing tissue, thereby causing experimental failure.

(2) The body surface of the animal is soft tissue, and the accuracy of the incisal trace marking is influenced by the posture adjustment.

When experimental animals are injured, the limbs of the animals are tied to fix the animals in a hanging mode so as to fully expose injured tissues. After the incisor line mark is finished, when the incisor line mark is positioned and adjusted, the body position of the experimental animal can be changed, the epidermis and the internal tissues of the experimental animal can be deformed along with the change of stress, so that the relative position of the experimental animal can be changed, the tissue to be injured deviates from the incisor line mark position, even if the incisor line position mark before positioning is accurate, the incisor line position mark can deviate due to positioning adjustment, and a repeatable standard experimental animal injury model is difficult to establish.
