One can insert the tubular structure in described implantable access sheath, and its head end is that pathological tissue takes out end, and it is inserting
After described implantable access sheath, pathological tissue takes out end and passes the head end of described implantable access sheath；Described passage tail
Cap can be arranged on the tail end of described implantable access sheath.
In a preferred embodiment, described passage nook closing member and the tail end taking pathology sleeve pipe are respectively provided with one handle.
In a preferred embodiment, also including an interim fixed handle of passage, the interim fixed handle of described passage exists
The afterbody of described implantable access sheath it is installed on when taking pathology sleeve pipe described in insertion and passage tail cap is installed.
In a preferred embodiment, the interim fixed handle of described passage includes being respectively provided with consolidating of semi-circular groove in the middle part of in the of two
Determining plate, the semi-circular groove both sides of fixed plate described in are each provided with a lock-screw wherein, in fixed plate another described
Semi-circular groove both sides respectively offer a locking hole corresponding with described lock-screw.
Due to the fact that and take above technical scheme, its have the advantage that present invention comprises implantable access sheath,
Nook closing member, take pathology sleeve pipe and tail cap, nook closing member put into the access sheath that model is suitable for, penetrates in the lump and take pathogenic site,
By access sheath being stayed site of puncture after taking pathology sleeve pipe taking-up bone pathology, access sheath caudal install
Tail cap, and access sheath screw-in is fixed on bone hole, thus reach to close the purpose of Puncture approach, it is possible to effectively block
The tumor tissues local diffusion of Puncture approach.
