Description
Technical field
The present invention relates to medicine instrument technical field, specially a kind of hypophysoma cuts remove device.
Background technique
Hypophysoma is one group from prehypophyseal tumour.Hypophysoma typically occurs between twenty and fifty period, usually can shadow
Growth and development, the reproductive function, study and work ability of patient are rung, clinical manifestation is hormone secretion abnormality disease group, oncothlipsis
Disease group, pituitary apoplexy and the performance of other hypofunction of anterior pituitary of hypophysis surrounding tissue.At present still to the treatment of hypophysoma
Based on operation, it is aided with drug therapy, radiotherapy.Around there are optic nerve, internal carotid, sea in the position of hypophysoma in saddle area
The important neuromechanism such as continuous sinus, hypothalamus, so operation still has certain risk.Operation method has through sphenoid sinus, opens cranium two at present
Kind mode, about 90% or more hypophysoma can take Trans-sphenoid surgery425 mode under scope to be cut off.Tumor diameter is big
It must reach optic nerve with optic nerve adhesion or the leading operative treatment of visually impaired tumour palpus, operation in 3 centimetres and sufficiently depressurize,
When carrying out hypophysoma cutting operation, because of tumour, the property overwhelming majority is softer, is easy to strike off and absorb with low pressure, thus mostly uses greatly
Stripper removing and suction tube attract, to prevent tumour " envelope " or saddle from influencing Tumors in saddle and cut every collapsing too early
It removes, should be by the excision sequence of first periphery rear center, currently, protruding into through sphenoid sinus, to carry out the removing mode striking off or absorb be main
Operation method protrudes into stripper through sphenoid sinus or suction tube is operated, since to protrude into space limited for sphenoid sinus, and need to make
It is pried through with endoscope, thus surgical doctor carries out the alternately and repeatedly use of stripper and suction tube, substantially prolongs hand
Art time, and when being removed by force by stripper, the operative skill of doctor is required high, tumour " envelope " confession can occur
Blood rupture of blood vessel, the phenomenon that causing subarachnoid hemorrhage, it is also possible to cause diaphragma sellae breakage leakage of cerebrospinal occur, to hard tough
The apparent tumour of adhesion is difficult thoroughly to cut off to influence surgical quality, and existing hypophysoma cutting remove device is installed negative mostly
Attractor is pressed, vacuum suction machine is also easy to produce reverse differential pressure when stopping using, flows backwards the hypophysoma in anti-neoplastic collection box,
Malpractice easily occurs, increases operation difficulty, and sucking head is chronically exposed in air and is easily infected with germs, increases bacterium in operation
A possibility that infection.
