Puncture needle fixation device for nephrology

Abstract

The invention discloses a puncture needle fixation apparatus for renal internal medicine. The puncture needle fixation apparatus comprises a poisoning seat used for positioning the puncture position of a patient and limit pieces used for adjusting depth of a puncture needle, a tubular lug boss is arranged on the upper end face of the positioning seat, a concave portion is formed in the center of the tubular lug boss, a needle hole penetrating the lower end face of the positioning seat is arranged in the bottom center of the concave portion, concave limit grooves matched with the limit pieces to limit the rotation angle of the limit pieces are arranged on two upper sides of the tubular lug boss, the limit pieces include a first limit piece and a second limit piece which are detachably connected, a first arc portion of a semicircular structure is arranged in the middle of the first limit piece, the limit pieces are fixed on the puncture needed through fixation of the first limit piece and the second limit piece with each other, constraint of puncture depth of the puncture needle is achieved by allowing lower end faces of the limit pieces to be abutted against bottoms of the limit grooves when the puncture needle penetrates the needle hole of the positioning seat. The puncture needle fixation apparatus is reliable in scheme implementation and capable of reducing operation difficulty and intensity of medical workers.

Description

Technical field [0001] The invention relates to the field of medical auxiliary appliances, in particular to a puncture needle fixing device for nephrology. Background technique [0002] At present, during intrarenal puncture treatment operations, most surgeons can only rely on personal experience to perform puncture needle puncture for the patient. In kidney puncture operations, the puncture needle usually needs to be inserted at a certain angle to facilitate subsequent testing equipment. Scanning and monitoring; especially during the operation, the stability of the puncture needle must be strictly ensured to prevent accidental injury caused by the needle slipping. Although there are some auxiliary stabilizers to assist the puncture needle fixation, most of them are not effective. Not only can it not effectively bring convenience to the operation, but it will also bring a certain degree of uncertainty to the operation, leaving the patient with a certain postoperative risk after t...

Problems solved by technology

[0002] At present, in the operation of intrarenal puncture, most of the surgeons can only rely on personal experience to perform the surgery for the patient with a puncture needle. Scanning and monitoring; especially during the operation, it is necessary to strictly ensure the stability of the puncture needle to prevent accidental injuries caused by the slipping of the needle. Although there are currently some auxiliary stabilizers to assist the fixation of the puncture needle, most of them are not effective. Not only cannot effectively bring convenience to the operation, but it will also bring a certain degree of uncertainty to the operation, leaving patients with certain postoperative risks after the operation.
