Description
Technical field
The invention belongs to technical field of medical instruments, and in particular to there is operation path during operations on cranium and brain and can protect
The effect of brain tissue, can effectively avoid damage to brain tissue, and deep operation can be carried out by having, especially in endoscopic surgery
In.
Background technology
It is complicated because brain deep and intraventricular tumor or vascular lesion position are deep, and brain tissue structure is tender, easily
Be damaged, focal area is reached in operation to be had through clinical operation approaches such as cortex fistulization approaches, unavoidably apparatus by when
Form brain tissue impairment repeatedly.Advocate at present after neurosurgery Minimally Invasive Surgery, especially nerve endoscope Technique Popularizing, encephalic is deep
Portion's operation can use endoscopic technic, so that deep art area is reached, but for showing brain tissue expansion and damaging less.But
Even if using nerve endoscope technology, it is still desirable to show that cortex fistulization enters brain tissue through brain tissue, and need to pull brain group
Knit, prevent its elastical retraction, operating theater instruments turnover can damage surrounding brain tissues repeatedly, the predominantly brain spatula skill previously used
Art, fixed inconvenience, and also brain spatula periphery can have incised injury to brain tissue, influence therapeutic effect.
Current existing technology, such as Chinese invention patent CN202843673U discloses a kind of endoscopic surgery auxiliary
Dilator, including two dilator pin, the cross sections of described two dilator pin is the same semicircle of radius size, and two supports
The semicircular opening for opening device cross section is relative；Opening of the top of described two dilator pin provided with two dilator pin foldings of control
Governor motion, and the abduction adjustment structure for controlling dilator foot bottom openings of sizes is respectively equipped with the top of each dilator pin.This
Invention, which forms a periphery, does not have important feature, and can suitably adjust the gap between dilator pin.It is unreasonable in the presence of expanding
And there is the big factor of surrounding brain tissues damage.
But previous patent technology does not accomplish that minimizing damage well enters art area, while reducing brain tissue as far as possible
Function that is expansion damage and protecting channel side wall brain tissue.
The content of the invention
It is easy to operate the technical problem to be solved in the present invention is to provide one kind is rational in infrastructure, less brain group can be passed through
Knit the damage of cortex fistulization and enter deep, then by the operation in passage, so as to avoid the damage week of apparatus turnover repeatedly
Side brain tissue, so as to improve the security of operation.
In order to solve the above technical problems, embodiments of the invention provide a kind of operation path external member, it is characterised in that including
Channel body A, inner core extension fixture B, the channel body A include sleeve 1, the connector 2 being connected on sleeve 1, and sleeve 1 is
Hollow channel design, uniform more than 3 an of side periphery of the connector 2 along sleeve 1；
The inner core extension fixture B includes internal core rod 4, head 5, enlarged portion 7 and charging portion 8；
Described channel body A sleeve 1 can be bounced back to the center of passage 3, stored, and be there is space inside passage 3 and accommodated inner core
Extension fixture B.
The sleeve 1 is hollow soft channel design, can be plastic material.
A side periphery of the connector 2 along sleeve 1 is uniform, and connector 2 is a banded structure, can pull open sleeve 1
Side forms passage.
The connector 2 and sleeve 1 have certain elasticity tension.
The enlarged portion 7 of the inner core extension fixture B is the structure being paperwrapped in internal core rod 4, can be injected by charging portion 8
Medium, such as air or water, expansion form cylindric.
There is bound edge 6 in the periphery of head 5 of the inner core extension fixture B, bound edge 6 can encase the enlarged portion 7 of protection retraction
End.
Also there is fixing device C, the fixing device C includes fix bar 9, retainer plate 10 and on retainer plate 10 with connecting
The through hole 11 that the quantity of fitting 2 matches, the end of connector 2 can be allowed to match, by and it is fixed.
The head 5 of the inner core extension fixture B is passivity head.
There is different lengths and cross section specification in the channel body A, length range is in 2-15cm, and cross-sectional diameter is in 1-
10cm。
There is different lengths and cross section specification in the enlarged portion 7 of the inner core extension fixture B, length range in 2-15cm,
Cross-sectional diameter is in 1-10cm.
The above-mentioned technical proposal of the present invention has the beneficial effect that：
A kind of operation path external member of the present invention can first be packaged together sleeve with inner core extension fixture, from brain tissue cortex
Fistulization, inner core head, which is punctured, enters brain tissue deep, by injecting gas flaring to the enlarged portion of inner core extension fixture, produces hand
Art passage, then pumpback gas and extracts inner core extension fixture, and indwelling sleeve is as operation path, by fixes sleeve, then
Nerve endoscope related equipment can repeatedly be passed in and out and performed the operation, and also avoid channel side wall from protecting brain tissue to avoid damage to, Yi Shengke
Suitable plant bulk is selected according to size of tumor and demand in preoperative and art, beneficial to operation.
