Minimally invasive locator for brain puncture

Abstract

The invention discloses a minimally invasive locator for brain puncture which comprises a Y axis locating rule, an X axis locating rule, a Z axis locating rule, a circular arc locating rule and a puncture needle guide seat, wherein the Y axis locating rule is located at the brain part of a patient; the X axis locating rule is glidingly arranged on the Y axis locating rule along the Y axis; the Z axis locating rule is glidingly arranged on the X axis locating rule along the X axis; the circular arc locating rule is glidingly arranged on the Z axis locating rule along the Z axis; the puncture needle guide seat is arranged on the circular arc locking rule and slides in the circular arc direction of the circular arc locating rule; a locating hole for a puncture needle for puncture location isformed in the puncture needle guide seat; and the circle center axial line of the positioning hole is intersected with circular center axial line of the circular arc locating rule. The minimally invasive locator has the advantages that medical workers can conveniently, fast and precisely locate the focus target spot; the optimal puncture point can be obtained by regulating the puncture needle guide seat; the problems that the focus target spot locating is difficult, and the puncture point cannot be selected are solved; the focus target spot locating operation steps are simplified; the puncturedifficulty is reduced; and the operation success rate is improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a minimally invasive locator for brain puncture. Background technique [0002] Diseases such as cerebral hemorrhage, hydrocephalus, brain abscess and brain cystic tumor are common clinical diseases in neurology. In the prior art, the surgical methods used to treat intracranial diseases mainly include craniotomy and puncture drainage. The former is more difficult, risky and expensive, and the latter is minimally invasive removal of intracranial hemorrhage or hematoma. It is clinically used because of its small trauma, safety, effectiveness, and low price. However, the quality and speed of the operation are affected to a certain extent because the puncture point cannot be accurately grasped objectively and is affected by human operation factors. And the various stereotaxic apparatuses that are used in clinic for skull puncture at present, because structure is complicated, price i...

Problems solved by technology

In the prior art, the surgical methods used to treat intracranial diseases mainly include craniotomy and puncture drainage. The former is more difficult, risky and expensive, and the latter is minimally invasive removal of intracranial hemorrhage or hematoma. It is clinically used because of its small trauma, safety and effectiveness, and low price. However, because the puncture point cannot be objectively and accurately grasped, and it is affected by human factors, the quality and speed of the operation are affected to a certain extent.

And the various stereotaxic apparatuses that are used in clinic for skull puncture at present, because structure is complicated, price is high, operation process is loaded down with trivial details, operation time is long, all is invasive screw fixation, has increased patient's misery, makes its clinical emergency Usage is limited
