Interventional puncture positioning device for neurology department

Abstract

The invention discloses an interventional puncture positioning device for the neurology department, and belongs to the technical field of medical auxiliary instruments, the interventional puncture positioning device for the neurology department comprises a connecting seat, the upper surface of the connecting seat is provided with a guide bin through two fixing blocks, and the upper surface of the connecting seat is fixedly connected with two clamping rings through a vertical plate; a gap between the opposite faces of the two clamping rings is slidably connected with a threaded cylinder. According to the interventional puncture positioning device for the neurology department, clamping rings, a threaded cylinder, limiting rings, a fixing ring and a first catheter are arranged, a rotating piece drives the threaded cylinder and the two limiting rings to rotate, the threaded cylinder is in threaded fit with a threaded rod between the two clamping rings according to rotation of the limiting rings, and the threaded rod pulls a rotating lantern ring to move; the rotary lantern ring rotates on the surface of the fixed ring through the two pressing rings to drive the puncture position of the rotary lantern ring to change, the mode can achieve adjustment and change of the puncture position and angle in the puncture process, positioning of the rotary lantern ring is more accurate, the operation requirement for doctors is greatly lowered, and use is safer and more reliable.

Description

technical field [0001] The invention belongs to the technical field of medical auxiliary instruments, in particular to a neurology interventional puncture positioning device. Background technique [0002] Neurology, as an independent secondary discipline, mainly provides targeted diagnosis and treatment for diseases of the nervous system, and the research methods basically overlap with those of internal medicine. Among them, the more common ones, such as lumbar puncture, are one of the means of neurological treatment. The puncture technique cooperates with CT and other technical means to achieve the effect of accurate pathological puncture. The current lumbar puncture method is that the patient lies on the side of the bed, and the doctor directly operates the needle through the hand to perform puncture. However, as the current puncture technology, In other words, the requirements for the doctor's operation and corresponding skills are extremely high, and hand shaking after p...

Problems solved by technology

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an interventional puncture positioning device for neurology, which solves the problem that the attending doctor of neurology relies too much on empirical judgment for puncture during actual operation and use, and is aimed at the doctor's needs. The operation level is relatively high, and it is difficult to accurately locate the puncture position, angle and depth
