Abstract
The ventricular anterior horn puncture positioning instrument has mainly one main plate and two auxiliary plates embedded via dovetail and dovetail slot in the angle of 90 deg. Each of the auxiliary plates has external auditory canal positioning slot and external auditory canal positioning knob inside the slot; and the main plate has direction pointer, and work hole with minimal distance of 2 cm to the direction pointer. The present invention has simple structure, can position, guide and puncture in 3D direction and has satisfactory clinical effect.
Description
Technical field
The present invention relates to a kind of Medical Instruments, be meant a kind of simple and easy ventricular anterior horn puncture positioning instrument especially.
Background technology
At present, ventricular puncture is clinical a kind of diagnosis, treatment means commonly used, and many under regular situation is target spot with the ventricular anterior horn, goes into method before the employing.This method is got 3cm behind the anterior hair line, and the other 2.5cm of center line is a point of puncture, and the inserting needle direction is parallel with sagittal plane, point to the imaginary line of two external auditory meatuss.Because what this method was used is manually control puncture, no objective criterion, aseptic hole-towel influences sight line in addition, punctures and successfully relies on the experience of operator to a certain extent.
Summary of the invention
The objective of the invention is to avoid above-mentioned weak point of the prior art, and propose a kind of simple in structure, can three-dimensional location, guiding, be punctured to the position finder of ventricular anterior horn.
Purpose of the present invention can reach by following measure: a kind of simple and easy ventricular anterior horn puncture positioning instrument, described ventricular anterior horn puncture positioning instrument include mainboard and two subplates, and they are by movably dovetail and dovetail groove tabling; Described mainboard and subplate length are all 15cm, and described mainboard has arm for direction indicator and working hole; Described two subplates have subplate regulating tank, subplate fixing button and external auditory meatus locating slot, in the described external auditory meatus locating slot external auditory meatus navigation button are arranged.
Further, described mainboard telescoping part indicates graduation mark.
Further, the angle of described master, two subplates is 90 °.
Further, the equal in length of described two subplates.
Further, described external auditory meatus locating slot symmetry, the other graduation mark that indicates of groove.
Further, described external auditory meatus navigation button is removable in the external auditory meatus locating slot, and by the fixedly female locking of Luo.
Further, described arm for direction indicator is vertical with the work mainboard, and can roll over.
Further, described working hole and arm for direction indicator minimum range are 2cm.
The present invention has following advantage compared to existing technology: the present invention is a kind of simple in structure, can three-dimensionally locate, lead, and is punctured to the position finder of ventricular anterior horn, and application has clinically obtained satisfied effect.

The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the invention.
As shown in Figure 1, 2, a kind of ventricular anterior horn puncture positioning instrument, described ventricular anterior horn puncture positioning instrument include mainboard 1 and two subplates 2, and they are by movably dovetail and dovetail groove 3 tablings, and mainboard 1 telescoping part indicates graduation mark, and the angle of major-minor plate is 90 °; The equal in length of two subplates 2, two subplates 2 have external auditory meatus locating slot 4, and external auditory meatus locating slot 4 symmetries, the other graduation mark that indicates of groove; External auditory meatus navigation button 5 is arranged in the external auditory meatus locating slot 4, and external auditory meatus navigation button 5 is removable in external auditory meatus locating slot 4, and by fixedly female 6 lockings of Luo; Arm for direction indicator 10 is arranged on the mainboard 4, vertical with mainboard 1, and can roll over; Working hole 9 is arranged on the mainboard 1, with arm for direction indicator 10 minimum ranges be 2cm.
During use, shown in Fig. 1,3, with the arm for direction indicator 10 of mainboard 1 with suffer from anterior hair line after the intersection point of 3cm and median line align, the left and right external auditory meatus of left and right external auditory meatus navigation button 5 alignment is fixed, regulating tank 7 in, regulate left and right subplate dovetail groove 3 and fix by subplate fixing button 8.As required by the direction of the arm for direction indicator left and right ventricular anterior horn that punctures.
