Puncture guide device for frontal horn of lateral ventricle

Abstract

The invention discloses a puncture guide device for frontal horn of lateral ventricle and relates to a medical device in neurosurgery. The puncture guide device comprises a cross beam and two vertical arms arranged at two ends of the cross beam, the profile of the puncture guide device is in the shape of an inverted U under front view, and a right-angle curved hook is arranged at the tail end of each vertical arm. Two puncture sleeves are arranged on two sides of the central line on the cross beam, parallel to each other and vertical to the cross beam, and central through holes are arranged on the puncture sleeves. The cross beam, the vertical arms, the right-angle curved hooks of the vertical arms and the puncture sleeves are positioned in a same plane. The puncture sleeves are arranged on the cross beam, the cross beam, the puncture sleeves, the vertical arms and the right-angle curved hooks of the vertical arms are positioned in the same plane, a frame for the guide device is always fixed in a puncture positioning point, and a puncture implement can perform puncture through the central through holes of the puncture sleeves, thereby really playing a drilling guiding role, ensuring that the puncture angle is correct, accurately pointing at a connecting line between two external auditory canals and reaching the lateral ventricle; and the guide device is convenient and objective to perform puncture, the drilling angle is accurate and has no deviation, and the guide device can ensure that an operation is successful.

Description

Technical field: [0001] The invention belongs to the field of medicine, and mainly relates to neurosurgery medical instruments, in particular to a puncture guide for lateral ventricle drainage in brain surgery. Background technique: [0002] Cerebrospinal fluid drainage through frontal horn puncture of the lateral ventricle is a commonly used diagnostic and therapeutic operation in neurosurgery. The success of frontal horn puncture depends on the location of the skull puncture point and on the direction and angle of the puncture. The location of the puncture point is easy to do according to the conventional method, that is, the point within the hairline (2cm) and 2.5cm on both sides of the centerline of the skull is taken as the drilling point. What is difficult to grasp is the direction and angle of the drilling process performed by the selected drilling point. When performing lateral ventricle puncture and drainage before the present invention, grasping the direction and a...

Problems solved by technology

Theoretically speaking, the orientation instrument will play the role of grasping the angle and controlling the drilling direction, but it is not the case in actual use, because the main board of the orientation instrument needs to be removed when drilling and puncturing, otherwise it will hinder the drilling, so In other words, when actually drilling, it means that the directional instrument is not used, which means that the directional instrument does not work, and the direction is still judged by subjective visual inspection, and there will still be deviations in the drilling angle.
