Epidural puncture device

Abstract

An epidural puncture device comprises a cross beam, first supporting legs, second supporting legs, filling liquid and a pressure sensor, the first supporting legs are arranged at the bottoms of the two ends of the cross beam, the second supporting legs are rotationally connected into the first supporting legs, a first rotating handle is arranged at the position, close to one end, of each second supporting leg, and a suction cup is installed at one end of each second supporting leg. A screw rod is rotatably connected to the middle part of the cross beam. One end of the screw rod is equipped with a second rotating handle. An elastic block is arranged on the inner side of each first supporting leg through a connecting rod, an opening is formed in the top of the elastic block, external threads are formed in the outer side of the top of the elastic block, a fastening sleeve is connected to the outer side of the elastic block in a screwed mode, and a connecting frame is arranged at the top end of a connecting rod; The middle of the elastic block is inserted with a puncture needle. The device is novel in structure, ingenious in conception, capable of conveniently adjusting the fixing position according to actual conditions, high in applicability, capable of monitoring pressure signals during puncture and conveniently judging the puncture position according to the pressure signals, high in puncture precision and beneficial to use.

Description

technical field [0001] The invention relates to a puncture device, in particular to an epidural puncture device. Background technique [0002] Anesthesia means "loss of consciousness, sensation". Loss of sensation can be localized, that is, reflected in a certain part of the body, or systemic, that is, manifested as a loss of consciousness throughout the patient's body and unconsciousness. From a medical point of view, the meaning of anesthesia is to temporarily lose the patient's overall or partial sensation through drugs or other methods, so as to achieve the purpose of painlessness and provide conditions for surgical treatment or other medical examination and treatment. [0003] Epidural anesthesia has been used clinically for more than 90 years, and has been gradually improved through continuous practice and research, and has become a commonly used method in clinical anesthesia. But failed epidural anesthesia is very common in clinical practice. An epidural is ineffec...

Problems solved by technology

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an epidural puncture device, which effectively solves the problem that the existing epidural puncture cannot be fixed well during operation and cannot be adjusted according to needs. At the same time, it is impossible to judge the puncture position well, which is not conducive to the operator's operation, the puncture accuracy is low, and it is not conducive to the treatment of patients.
