Abstract
This utility model relates to a kind of stereotaxis intracranial puncture positioning head frame, comprises guide rail, guide rail two ends be fixed with respectively in the same way to side gauge bar and homonymy guide rod; Guide rail is provided with the slide block that can slide, slide block is fixed with to side gauge bar middle guide rod in the same way; The tip of homonymy guide rod and middle guide rod all offers bullport; By be fixed with respectively at guide rail two ends in the same way to side gauge bar and homonymy guide rod; Guide rail is provided with slide block, slide block is fixed with middle guide rod, thus can position by only regulating middle guide rod and fix; Because the tip of homonymy guide rod and middle guide rod all offers bullport, thus orientation, the puncture of depthkeeping guiding haematoma cavity can be carried out, therefore, it is possible to improve hematoma puncture success rate of operation, save time, improve the paracentetic therapeutic effect of haematoma cavity.This apparatus structure is simple simultaneously, and preoperative planning only needs the conventional head CT inspection of row, easy and simple to handle, is convenient to clinical widespread adoption.
Description
Technical field
This utility model relates to a kind of intracranial positioning head frame, is specifically related to a kind of stereotaxis intracranial puncture positioning head frame.
Background technology
Cerebral hemorrhage is the common Severe acute disease of neurosurgery.The paracentesis of sphenotresia haematoma cavity have good therapeutic effect in cerebral hemorrhage treatment.But because hematoma is positioned at brain in art, patient can not look at hematoma straight, can only carry out blind wearing by experience to hematoma.Like this, likely cause puncture tube position to offset hematoma center, be even positioned at outside haematoma cavity, especially comparatively dark for position and measure little hematoma, affect surgical effect and even cause operative failure.In art, apply that horseley-Clarke technique carries out orientation to puncture, depthkeeping will contribute to improving puncture accuracy and success rate of operation.
In clinical, there is tridimensional orienting headstock to apply at present, but be applied to functional neurosurgery surgery more.Its puncture accuracy is high, can reach subnucleus group level, but there is the problem that operation is not convenient, preparation amount is large, time is long.Be unfavorable for clinical in cerebral hemorrhage treatment widespread adoption.
Utility model content
The purpose of this utility model is to overcome the shortcoming existed in above-mentioned prior art, provides a kind of stereotaxis intracranial puncture positioning head frame, has puncture accuracy high, simple to operate, the advantage that time is short.
For achieving the above object, this utility model by the following technical solutions: comprise guide rail, guide rail two ends be fixed with respectively in the same way to side gauge bar and homonymy guide rod; Guide rail is provided with the slide block that can slide, slide block is fixed with to side gauge bar middle guide rod in the same way;
Described homonymy guide rod and the tip of middle guide rod all offer the bullport with guide rail parallel.
Described is all fixedly welded on guide rail side gauge bar and homonymy guide rod.
For being welded and fixed between described slide block and middle guide rod.
Described slide block is provided with the slider locks screw for itself and guide rail being fixed.
Described slide block is assembling slide block, and fixes through some screws.
Being provided with the body of rod side gauge bar tip is the cone of 90 ° of angles; The bullport on homonymy guide rod and middle guide rod is pointed at the tip of cone, and the centrage of cone overlaps with the bullport centrage on homonymy guide rod and middle guide rod.
Described middle guide rod is L-type, and its top is fixed on slide block, and bottom bending segment runs through through bullport.
Bending segment bottom side gauge bar tip and middle guide rod is oppositely arranged, and is in phase co-altitude.
This utility model has following beneficial effect: prior art of comparing, this utility model by be fixed with respectively at guide rail two ends in the same way to side gauge bar and homonymy guide rod; Guide rail is provided with slide block, slide block is fixed with middle guide rod, thus can position by only regulating middle guide rod and fix; Because the tip of homonymy guide rod and middle guide rod all offers bullport, thus orientation, the puncture of depthkeeping guiding haematoma cavity can be carried out, therefore, it is possible to improve hematoma puncture success rate of operation, save time, improve the paracentetic therapeutic effect of haematoma cavity.This apparatus structure is simple simultaneously, and preoperative planning only needs the conventional head CT inspection of row, easy and simple to handle, is convenient to clinical widespread adoption.
Further, due to side gauge bar tip conically, thus head can be made fixing more more firm.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, this utility model comprises guide rail 1, guide rail 1 two ends be welded with respectively in the same way to side gauge bar 2 and homonymy guide rod 6, to side gauge bar 2 tip conically structure; Guide rail 1 is provided with the slide block 7 that can slide, slide block 7 is welded with to side gauge bar 2 middle guide rod 3 in the same way; Homonymy guide rod 6 all offers the bullport parallel with guide rail 1 with the tip of middle guide rod 3; Slide block 7 is provided with slider locks screw 4, slide block 7 is assembling slide block, and fixes through some screws 5, and being provided with the body of rod side gauge bar 2 tip is the cone of 90 ° of angles; The bullport on homonymy guide rod 6 and middle guide rod 3 is pointed at the tip of cone, and the centrage of cone overlaps with the bullport centrage on homonymy guide rod 6 and middle guide rod 3; Middle guide rod 3 is in L-type, and its top is fixed on slide block 7, and bottom bending segment runs through through bullport, is oppositely arranged, and is in phase co-altitude to bending segment bottom side gauge bar 2 tip and middle guide rod 3.
First clinician can touch its head CT coupon when running into Patients with Cerebral Hemorrhage; Choose maximum planes, maximum planes is selected puncture entry point A, the most advanced and sophisticated point B of puncture tube; So, desirable puncture direction is namely represented by A to the ray of B; Ray AB and right side scalp intersection point are C point; Therefore ray AC also represents puncture needle inserting needle direction, and the length of line segment AB is puncture depth of needle, as Fig. 4 shows.
For going out A, C 2 point at scalp surface accurate marker, label can be attached in scalp surface, and then check head CT confirms, as Fig. 5 shows.
Complete head CT inspection again and confirm that Preoperative Method is carried out after errorless in A, C 2 positions.Otch is done, row sphenotresia in A point place in art; The headstock is fixed in ready rear application, will aim at C point, and A point is aimed at by the most advanced and sophisticated tubular structure of middle guide rod to side gauge bar conical structure, fixing slide block; Import drainage tube into through homonymy guide rod and the most advanced and sophisticated tubular structure of middle guide rod, and thrust in brain, reach constant depth and can obtain desirable puncture position.
Preoperatively to locate drafting puncture line and scalp surface point of intersection, check head CT, in art, utilize the headstock to penetrate drainage tube to haematoma cavity, until desired depth along 2 lines.Reach directed, depthkeeping punctures object.
