Detain 45 it is movable be located on the body of rod 44, the push-pull rod 32 is pulled away from towards the direction far from the cylinder 31 to scheduled cylinder
Stop being pulled away from when 31 scale, the body of rod 44 fastens the buckle 45 at this time, and the buckle 45 offsets with the ring support 312
Only, prevent the body of rod 44 from moving again, so that push-pull rod 32 be effectively prevent to bounce back in cylinder 31 and the phenomenon that back pressure occur.
The present invention also provides a kind of application methods of brain aspiration biopsy device:
S1: it determines the target site that brain aspiration biopsy device needs to puncture, extracts needle after needle body 1 is penetrated into target site
Core 12；After the depth for first determining the direction and inserting needle that need brain to puncture under CT guidance in this step, needle body 1 is penetrated into mesh
Then cursor position extracts needle core 12, hollow tack needle 11 is only stayed to puncture target position；
S2: being sequentially connected the filter device 2 and the negative pressure suction device 3 for hollow tack needle 11, and then movement pushes away
Pull rod 32 to generate negative pressure in cylinder 31, and in this step, the push-pull rod 32 is pulled away from towards the direction far from the cylinder 31
Stop being pulled away from when drawing to scheduled 31 scale of cylinder, then fasten the buckle 45 prevent its from move again and with the ring
Support 312 offsets only, so that effect prevents push-pull rod 32 from bouncing back in cylinder 31 and the phenomenon that back pressure occur；
S3: by the push-and-pull of the repeated multiple times 1cm of hollow tack needle 11 or so, so that brain tissue is inhaled under subnormal ambient
In filter collector 21 and until be drawn into the brain tissue of filter collector 21 does pathologic finding enough, it is collected by filtration in this step
Device 21 is by being collected the brain tissue of suction；
S4: finally pulling out hollow tack needle 11, the brain tissue inspection that will be collected in filter collector 21.
The technology of the present invention effect major embodiment is in the following areas:
1. since hollow tack needle end part and needle core end form obtuse, so that subtracting significantly when piercing through lax brain tissue
The problem of damaging blood vessel and injuring nerve less.
2. since needle body, filter device and negative pressure suction device are detachable setting, so that fixed when puncture to destination organization
Position is more convenient and safe.
3. being stuck in by the locating piece at corresponding graduation mark, can prevent from changing at external cause (such as external force) real
Border needs the depth of inserting needle, thus accurate control depth of needle.
4. the distance caging device is set to the cylinder back-end, to be moved to the stroke limit dress when the push-pull rod
The cylinder is made to form predetermined negative pressure when the predetermined position set, so that push-pull rod can not be mobile relative to cylinder, it is effectively anti-
Thrust pull rod bounces back in cylinder and the phenomenon that back pressure occurs.
Certainly, above is representative instance of the invention, and in addition to this, the present invention can also have other a variety of specific implementations
Mode, all technical solutions formed using equivalent substitution or equivalent transformation, is all fallen within the scope of protection of present invention.
