Ultrasonic guiding, positioning and adjusting device for animal in vivo tissue accurate injury

Abstract

The invention relates to an ultrasonic guiding, positioning and adjusting device for animal in vivo tissue accurate injury. The ultrasonic guiding, positioning and adjusting device comprises a rotating supporting foundation support and a base, wherein the rotating supporting foundation support is used for supporting the whole regulating device body, so that height adjustment and rotating operationof the whole regulating device are realized; the bottom end of the base is connected with the rotating supporting foundation support; a fixed platform is arranged at the top end of the base; a tilting platform is hinged to a position away from the top end of the base, of the fixed platform; an up-and-down lifting mechanism is arranged at one end away from a hinging shaft, of the tilting platform;a front-and-rear moving mechanism, a left-and-right moving mechanism and a front-and-rear tilting mechanism are sequentially arranged between the fixed platform and the base from top to bottom; an ultrasonic guiding and positioning device comprises an ultrasonic diagnostic apparatus, an ultrasonic probe, a puncturing guiding frame, a laser positioning device and a puncture needle; a supporting rod is arranged on one side adjacent to the up-and-down lifting mechanism, of the fixed platform; the laser positioning device is connected with the supporting rod; and the laser positioning device performs up-and-down longitudinal motion, horizontal lateral motion and universal rotating adjustment along the supporting rod.

Description

technical field [0001] The invention relates to the technical field of animal wounding experimental devices, in particular to an ultrasonic-guided positioning adjustment device for precise wounding of tissues in animals. Background technique [0002] When studying the on-site hemostasis or wound repair of gun penetrating wounds or blind wounds, ballistic guns are often used to accurately wound specific tissues in animals, such as organs or blood vessels, to simulate the wounding effect of specific parts of the human body under battlefield or anti-terrorism conditions. Establish a standardized animal injury model as the basis for the structural design and effect evaluation of hemostatic materials and hemostatic devices. [0003] In order to establish a standardized animal model for accurate injury, it is necessary to ensure that the flight trajectory of the bullet fired by the ballistic gun has good repeatability. In the injury experiment, a special ballistic gun is usually u...

AI Technical Summary

Problems solved by technology

For example, when the depth of injury is 100mm, the deviation of the incident angle of 10° will cause the bullet to deviate from the expected track by 17mm. causing the experiment to fail

[0010] (2) The animal body surface is soft tissue, body position adjustment will affect the accuracy of notch line marking

Remember that after the line marking is completed, the position of the experimental animal will change when the positioning is adjusted, and the epidermis and internal tissues of the experimental animal will deform with the change of force, resulting in a change in relative position, causing the tissue to be injured to deviate from the incision line Mark the position, even if the position of the anterior notch line is accurately marked, it will deviate due to positioning adjustment, making it difficult to establish a repeatable standardized experimental animal injury model
