Adjustable puncture device for pathological examination

Abstract

The invention relates to an adjustable puncture device for pathological examination. The adjustable puncture device for pathological examination comprises a base, two first vertical plates fixed on the base and perpendicular to the base, two second vertical plates slidably arranged in the two first vertical plates, and a steering plate rotatably installed between the two second vertical plates. When sampling work of pathological examination is carried out, an elastic driving mechanism works in the forward direction, the penetrating depth of a puncture needle is controlled through a display device, the puncture needle stores corresponding elastic potential energy, a direction adjusting mechanism works to drive the steering plate to ascend or descend, the puncture needle is adjusted to a proper puncture height, then the steering plate is driven to drive the puncture needle to rotate, so that the puncture angle is adjusted, the elastic potential energy stored by the puncture needle is released, the elastic driving mechanism works reversely, finally, the puncture needle punctures into a body cavity of a patient, and in the movement process of puncturing into the body cavity of the patient, a speed reduction assembly is used for reducing the speed.

Description

technical field [0001] The invention relates to the related technical field of medical auxiliary equipment, in particular to an adjustable puncture device for pathological examination. Background technique [0002] Puncture, a commonly used surgical term in medicine, is a diagnosis and treatment technique in which a puncture needle is inserted into the body cavity to extract secretions for testing, injecting gas or contrast agent into the body cavity for contrast examination, or injecting drugs into the body cavity. The purpose of puncture is to draw blood for testing , Blood transfusion, infusion and catheterization for angiography. [0003] However, the existing puncture device, in the process of use, the depth of the puncture needle into the patient's body cavity is usually controlled by the medical staff by virtue of their senses, and does not have the corresponding adjustment and control function. Patients cause unnecessary injuries, and in actual use, the ideal effect...
