Specific implementation mode
- Fig. 3 is please referred to Fig.1, the utility model is self-expanding no-station pole canopy keyhole surgery lane device comprising channel part 1
And puncture portion 2.
Channel part 1 is whole cylindrical, and channel part 1 includes braced frame 11 and cover film 12；Braced frame 11 is arranged
In cover film 12.Preferably, cover film 12 includes theca interna 121 and theca externa 122, and theca interna 121, theca externa 122 divide
Other lining is bonded to each other in the inside of braced frame 11, the outside of braced frame 11, and theca interna 121 with theca externa 122, to
Braced frame 11 is set to be arranged in cover film 12.Above structure is convenient for the processing of channel part 1.
Cover film 12 is usually that latex is made, naturally it is also possible to is made of other medical materials, such as e-PTFE second
Alkene (ePTFE) etc..
Braced frame 11 by reticular structure, be usually medical metal be made.Preferably, braced frame 11 is memory wire
It weaves.It is woven more specifically, braced frame 11 is niti-shaped memorial alloy silk.Used nickel-titanium shape memory
The recovery temperature of alloy can be between -10 DEG C -55 DEG C, usually between 20 DEG C -37 DEG C, preferably 33 DEG C.
Puncture portion 2 includes sequentially connected from swollen device 23 and connecting tube 24；Be made from swollen device 23 for flexible material,
And with 24 unicom of connecting tube.Preferably, it is non-compliance sacculus from swollen device 23.In general, from swollen device 23 be polyvinyl chloride
(PVC) it is made.
Channel part 1 folds rear enclosure from swollen device 23.
The operation principle of self-expanding no-station pole canopy keyhole surgery lane device in the utility model is：At the beginning of braced frame 11
Beginning shape is cylindrical shape；Using it is preceding by channel part 1 fold (if braced frame 11 be niti-shaped memorial alloy silk weave,
Then need to fold at a temperature of less than recovery temperature) from swollen device 23.
When needing to appear intracerebral lesion, specified position is delivered to by channel part 1 and from swollen device 23, then by gas injection
Device (attached drawing is not drawn into, such as syringe, compression pump etc.) and 24 unicom of connecting tube, and gas is injected to from swollen device 23,
By expansion from swollen device 23 channel part 1 is extended for original shape after by channel part 1 and from the extraction of swollen device 23 it is (logical
It often needs to take out the extraction section gas from from swollen device 23 by gas injection device, to reduce the volume from swollen device 23, make from swollen
Device 23 is convenient for being extracted), intracerebral lesion can be manifested from channel part 1 (i.e. the hollow part of channel part 1).
It is woven if braced frame 11 is niti-shaped memorial alloy silk, it can (attached drawing not be drawn by gas injection device
Go out, such as syringe, compression pump etc.) high-temperature gas (such as 37 DEG C of gas) is injected to from swollen device 23, passing through expansion
It, can be with also by transmitting heat after expansion from swollen device 23 to channel part 1 while expanding channel part 1 from swollen device 23
Make braced frame 11 fully, rapidly revert to original shape, so as to increase appearing for diseased region, contribute to lesion
Elimination or excision, operating time can also be shortened.
Further, it is further fixedly arranged on set 22 of threading a needle from the front end of swollen device 23, the front end for set 22 of threading a needle is additionally provided with
Draw point 21.For example, the tail end setting hole for set 22 of threading a needle, the tail end for set 22 of threading a needle is inserted into from the front end of swollen device 23, is threaded a needle
The tail end of set 22 shrinks, is clamped from the front end of swollen device 23.By draw point 21 and set 22 of threading a needle, piercing method may be used will
It is delivered to specified position, brain tissue is pulled without brain spatula, it is very light to brain tissue compressing, even if operating time
It is long to produce serious influence to brain tissue and serious complication, substantially reduce operation risk.
Further, the thread a needle front end of set 22 is additionally provided with guide pad 221, and guide pad 221 is whole in cone.It can rise
To guiding role, scratch brain tissue when preventing from puncturing.
