Portable percutaneous puncture locating device and locating method implemented via device

Abstract

The invention discloses a portable percutaneous puncture locating device and a locating method implemented via the device. The device comprises a locating frame, a rotary piece and a scale ring, wherein an arc-shaped groove is formed in one end of the locating frame, and angle scales, along the circumferential direction of the arc-shaped groove and the outer wall surface of the scale ring, are arranged on the outer wall surface of the end; the rotary piece comprises a locating end and a rotating end; the locating end of the rotary piece is overlapped with the circle center of the arc-shaped groove; a power unit, by which the locating end of the rotary piece can be driven to rotate, is arranged in the locating frame; the rotary piece can move along a radial direction of the arc-shaped groove; one end of the scale ring is connected to the rotary piece, so that a plane where the scale ring is located is perpendicular to a plane where the end of the locating frame is located; a guide blockis connected to the scale ring; a guide hole, in which a puncture needle is inserted, is formed in the guide block; and a central shaft of the guide hole points to the circle center of the arc-shapedgroove. The puncture guidance device provided by the invention is simple in structure, easy to disinfect and low in cost; and the device is simple and convenient to operate and relatively short in locating duration, and radiation quantities to a patient and operators can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a portable percutaneous puncture positioning device and a positioning method realized by the device. Background technique [0002] With the continuous improvement of the concept of minimally invasive spinal surgery and the continuous development of minimally invasive technology, the discipline has gradually moved from the direction of minimally invasive surgery to precision, digitalization, and intelligence. Many scholars define modern minimally invasive spinal surgery as a comprehensive discipline that integrates digital, intelligence, navigation technology, and endoscopic technology into spinal surgery. Similar to open surgery, minimally invasive spinal surgery uses one or more tiny incisions or puncture channels, uses special instruments and devices, and completes the puncture under the monitoring of imaging equipment or guidance of navigation technology.

Problems solved by technology

These devices have their own deficiencies. The first type of operator needs to be an experienced physician. In addition, multiple perspective positioning is required to adjust the direction, angle and depth of the puncture needle in order to obtain a satisfactory puncture point and puncture path. Moreover, when the operator adjusts the puncture direction according to the hand feeling, the peripheral nerves and blood vessels will be stimulated. Most importantly, multiple fluoroscopy increases the radiation dose of the patient and the operator; It is difficult for most hospitals to implement; the third spinal positioning device is currently in the exploratory stage, and the clinical feasibility and navigation accuracy need to be improved, and most of the equipment is large and difficult to sterilize. Puncture angle and depth, when the puncture position is changed due to patient movement, the parameters need to be readjusted, which relatively increases the operation time, blood loss and infection risk, etc.
