Problems solved by technology

Due to the sterile drape during the operation, body surface landmarks such as the tip of the nose and the external auditory canal are covered, and the midpoint of the line connecting the bilateral external auditory canals is an imaginary point in the internal space of the skull, which cannot be viewed directly. Therefore, the traditional positioning method is limited; even if the initial positioning is relatively accurate , it is also prone to direction deviation during the puncture process

Embodiment Construction

[0015] In order to make the objects and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0016] Such as figure 1 As shown, the embodiment of the present invention provides an anterior horn puncture auxiliary positioning instrument, including a positioning frame 1 and an infrared positioning lamp 2. The positioning frame 1 includes a left side AD, a right side BC, and a top side AB. and the rectangular frame formed by the bottom edge DC, the two ends of the bottom edge DC are symmetrically installed with earplug installation rods H and I through screw buttons F and G, and the earplug installation rods H and I have scales to ensure that CI=DH, The distance from the two sides of the head frame to the outer ear door is equal; it also i...

Abstract

The invention discloses an auxiliary positioner for lateral ventricle frontal horn puncture, comprising a positioning frame and an infrared positioning lamp. The positioning frame includes a rectangular frame composed of a left side AD, a right side BC, a top side AB and a bottom side DC; two ends of the bottom side DC are symmetrically fitted with earplug mounting rods H and I respectively through screw knobs F and G; the earplug mounting rods H and I are provided with graduation marks, with CI=DH ensured; two sides of a head rack are equally far away from the external acoustic pore; the auxiliary positioner also includes a steel rod M and a steel rod J; the top side AB is movably fitted with an N part and a K part; the K part is arranged in the midpoint of the top side AB; the upper endof the steel rod J is passed through the K part; the lower end of the steel rod J is movably fitted with a Q part; the Q part is a plastic sheet with graduation marks and can move up and down along the steel rod J, and the Q part is used for measuring a horizontal distance from a P point to the steel rod M. The auxiliary positioner is simple in structure and convenient to use, can provide linear positioning and is suitable for guiding a puncture direction.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an auxiliary positioning instrument for puncturing the anterior horn of the lateral brain. Background technique [0002] Puncture of the anterior horn of the lateral ventricle is a common surgical operation in neurosurgery. It is used for the treatment of hydrocephalus and ventricular hemorrhage, and requires precise puncture direction. Due to the sterile drape during the operation, body surface landmarks such as the tip of the nose and the external auditory canal are covered, and the midpoint of the line connecting the bilateral external auditory canals is an imaginary point in the internal space of the skull, which cannot be viewed directly. Therefore, the traditional positioning method is limited; even if the initial positioning is relatively accurate , it is also prone to direction deviation during the puncture process. Contents of the invention [0003] In order to solve th...
