Description
Technical field
The present invention relates to the field of medical instrument technology more particularly to a kind of cornu frontale ventriculi lateralis guiding puncture devices.
Background technology
Cornu frontale ventriculi lateralis puncture is that neurosurgery carries out Ventriculo peritoneal shunt and the common operation of extraventricular drainage operation.Volume
The parameters such as position, angle, the depth that angle punctures are the key that Ventriculo peritoneal shunt and extraventricular drainage operation success or failure.
Before the preferable position of puncture of frontal angle is homonymy telocoele Men Shi holes (i.e. Monro holes), in the separate ventricles of the brain choroid plexus and
Telocoele wall.Common method is single-handedly to puncture, and point of puncture is 2cm in hairline, 2.5cm on the outside of head median line.Puncture procedure
When, puncture needle is directed toward offside endocanthion in oblique coronal plane, in sagittal plane by bilateral external auditory meatus line, slow inserting needle is about
4cm or so has cerebrospinal fluid spilling, is put into about 1.5cm or so further along.Operator is needed with oneself subjective sensation, and assurance punctures through
Angle of the puncture needle on coronal-plane and sagittal plane in journey, even high seniority doctor is also difficult to find preferable puncture position accurately,
Still more feldsher.Therefore, it is commonplace to there is the situation of puncture angle deviation, foreign literature report, the ratio that ideal punctures
Example is only 40% or so.
Certainly, can also be come in the hospital perfected in equipment using instruments such as stereotactic apparatus, intraoperative ultrasound, navigators auxiliary
Carry out puncture procedure is helped, can so reach very high precision.But due to exist spend high, cumbersome, consuming duration etc. because
Element, greatly patient both domestic and external there is no condition using above-mentioned Medical Devices, and condition is simple and crude, situation it is pressed for time
Under, many operations can not also be equipped with above-mentioned Medical Devices in time.
The problem of for more than, some doctors once designed, made it is relatively simple punctured for cornu frontale ventriculi lateralis it is auxiliary
Help device.
For example, Fig. 1 be the prior art puncture direction finder structure diagram, as shown in Figure 1, puncture direction finder by
The semicircle mainboard of angle index is indicated to determine to puncture the puncture direction of conduit, the puncture conduit on the semicircle mainboard is always
It is directed toward the midpoint of bilateral external auditory meatus.However, preferably Monro holes not on the line at point of puncture Yu bilateral external auditory meatus midpoint,
So theoretically i.e. there are larger errors for puncture direction finder.
For another example, Fig. 2 is the puncture gate apparatus structure diagram of the prior art, as shown in Fig. 2, puncture gate apparatus is vertical at two
Crossbeam is set on arm, and trocar sleeve is vertically set on crossbeam, and lancet device is punctured along the central through hole of trocar sleeve.
However, cornu frontale ventriculi lateralis puncture on oblique coronal-plane be there are one angle of inclination, so just can guarantee ventricles of the brain cannula tip with
Telocoele wall does not contact, this puncture gate apparatus is a vertical puncturing, it is difficult to ensure to puncture ideal position.
Therefore, it using being simple and convenient to operate, having the high puncture auxiliary device for puncturing precision is this field skill to design a kind of
The technical issues of art personnel are urgently to be resolved hurrily.
The content of the invention
