Further, puncture tube 2, tube filler 1, set to remove and be respectively marked with length unit mm number on cylinder 3 and opening frame 4, be easy to use
Person observes with carrying out merging brain tissue and haematoma cavity depth.
Optionally embodiment, the claw 42 and the length of tube body 41, outer diameter of opening frame 4 are of different sizes, for not
It is used in different operations with size and quantity of hematoma.
41 length of tube body can be 70mm, 50mm or 30mm, and 41 internal diameter of tube body can be 17mm, 16mm or 15mm, and blade 421 is long
Degree can be 55mm, 45mm or 35mm, blade 421 is stretched out naturally to be formed elliposoidal diameter and can make for 35mm, 30mm or 25mm
The specification of different parameters various combination is used for different shape and quantity of hematoma patients surgery out.
Since the case where clinically hemotoncus of 40-50 milliliters of elliposoidal forms, cortex are away from hemotoncus center 7cm or so, is most,
A kind of optimal case, the total length of tube filler 1 are 16cm, and diameter 1.5cm, the bullet end of tube filler 1 is 2cm, the central duct of tube filler 1
Length 16cm, diameter 3mm, strip 11 is 16cm long, wide 1mm, high 1mm.
Setting and removing the length of cylinder 3 is 12cm, diameter 17cm, sets the barrel thickness 1mm for removing cylinder 3, the wide 1.5mm of side vacancy.The
The wide 1cm of one handle 32, long 3cm, thick 0.2cm.
The tip that the junction width of the setting of blade 421 4 of claw 42, blade 421 and tube body 41 is greater than blade 421 is wide
Degree, further, a length of 6cm of blade 421, blade 421 and the junction width of tube body 41 are 0.5cm, and the tip of blade 421 is wide
Degree is 0.2cm.4 blades 421 strut to form a length of 4.5cm in elliposoidal space, wide 3cm naturally.6cm long, the outer diameter of tube body 41
1.65cm.The handle of tail end side one of opening frame 4, wide 1cm, long 2cm, thick 0.2cm.A length of 0.2cm of cross bar.
The application method of this equipment are as follows:
The preoperative distance that quantity of hematoma and inlet point to target point are calculated with 3D-Slicer software, into channel and 3
The angle of plane.1.5cm before design notch coronal suture, 2.5cm is opened by middle line, is about 4.0cm straight cut, mastoid process dilator retracts
Scalp exposes skull, the small bone flap of milling cutter form diameter about 2.5cm after drilling, and "+" cuts endocranium.Puncture tube 2 can be accurately placed in
To hemotoncus center, there is hemotoncus liquid stream to go out and illustrate to puncture successfully, the interior needle core of removal connects syringe, and to pump out several milliliters of hemotoncus preliminary
Decompression.
Claw 42 is closed up and removes the slowly merging haematoma cavity of cylinder 3 by setting, claw 42 is removed 3 rear blade 421 of cylinder and stretched out by setting
Among hemotoncus, fixed opening frame 4.It is softly sucked out within the scope of the elliposoidal that opening frame 4 is formed with scope combination aspirator
Hemotoncus, more tough and tensile secured hemotoncus can match syzygies physiological saline and tumor pincers etc. taken to be caught broken suction.First four are removed to strut between piece
Most of hemotoncus, four strut below piece hemotoncus or strut piece overlay area can be subsequent by the exposure of coaxial rotating opening frame 4
It is continuous to remove, until hematoma clearance is satisfied.Active hemorrhage point is encountered, can stop blooding using bipolar electrocoagulator, remove 3, cylinder using setting
Opening frame 4 is carefully withdrawn from from haematoma cavity.
The utility model has the following beneficial effects: the present invention is using hemotoncus the distracted pathological anatomy shape of normal cerebral tissue
State is placed in opening frame 4, and the claw 42 of opening frame 4 struts to form working space, for the interior of cerebral hemorrhage scope hematoma clearance operation
The operation tools such as mirror, aspirator, bipolar electrocoagulator provide maximized working space；Secondly because 42 elasticity of claw is placed in, is clear
When withdrawing from after except hemotoncus, elasticity, which passes through to set after closing up, removes the damage that the extraction of cylinder 3 does not aggravate normal brain activity cortex operation path.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with the power
Subject to the protection scope that benefit requires.
