Description
Technical field
The utility model relates to a kind of backbone stereoscopic localized rulers, belong to medical instruments field.
Background technique
When row posterior spinal operation, especially thoracic vertebrae and waist chest section are performed the operation, often because determining that sick vertebra and vertebral pedicle puncture point are tired
It is difficult and have an X-rayed repeatedly, it wastes time, or even positioning mistake occurs, needs to extend operative incision, increases exposure range, lead to spinal cord
The complication such as neurotrosis.
There are many conventional spinal localization method, respectively there is limitation: (1) anterior superior spine positioning mode is more fat to figure or regression causes
The unclear person of interspinal interstice easily causes erroneous judgement, and this method relies on the experience of doctor, and accuracy rate is lower, at present clinically very
It is few to use.(2) rib cage positioning mode is more demanding to the clarity of preoperative X-ray film agent fluoroscopy during operation, intestinal gas and excrement have by
The judgement to T12 rib cage is influenced, in addition some backbones are easy to cause there are inborn variation, such as lumbarization, sacralization etc.
Mistake is positioned, so typically just supplementary means.(3) skin marker positioning mode is current clinical more common positioning side
Method, but since piece position is inconsistent or skin movement leads to the position corresponding with bone spinous process of the mark on skin positioned at taking the photograph for body in operation
It sets generation movement and keeps positioning very inaccurate, especially to fat patient, error is bigger.
Chinese patent CN206587051U discloses a kind of backbone body surface locator, including two piece of first positioning plate and two pieces
Second positioning plate, two pieces of first positioning plates are arranged in parallel, and two pieces of second positioning plates are arranged in parallel, and the first positioning plate
