Afterwards, people utilize the human body naturals' such as nasal cavity physiology lacuna (the passage periphery does not have important feature), nerve endoscope and assistive device are performed the operation this sheath outer operation that is called outside working sheath, because scope light passes through air ambient, claim again the air ambient endoscopic surgery simultaneously.Because the sheath outer operation can use the larger suction pump of relative diameter and other apparatus, can process active hemorrhage, clot and some tumor, and a small amount of hemorrhage visual area of can not causing is unclear.Typical sheath outer operation has the per nasal surgery of skull base tumor that hypophysectomizes.The major advantage of sheath outer operation is to break away from the constraint of scope working sheath, but it needs a periphery not have the passage of important feature.
Intracerebral lesion (such as intracerebral hematoma) and Intraventricular focus (such as tumor and hematoma) are because of non-existent natural physiology lacuna passage, and the Minimally Invasive Surgery of employing nerve endoscope must be for performing the operation its scope of application of drawbacks limit of operation in the sheath in the sheath.This has caused vast neurosurgery worker's thinking, and previously also someone improves working sheath of nerve endoscope, wishes to make these operations become the sheath outer operation.Even but the working sheath after improving also all can not be regulated openings of sizes, has some defectives, be difficult in real work, use, promote.
Summary of the invention
The object of the invention is to, for the deficiencies in the prior art, provide a kind of endoscopic surgery to assist dilator, form a periphery and do not have important feature, and be the artificial gap that suitably to regulate, make the diseases such as the intracerebral lesion of non-existent natural physiology lacuna and Intraventricular focus can use the sheath outer operation, thereby enlarge the scope of application of nerve endoscope Minimally Invasive Surgery.
Technical scheme of the present invention is, a kind of endoscopic surgery is assisted dilator, comprises two dilator feet, and the cross section of described two dilator feet is the same semicircle of radius size, and the semicircular opening of two dilator cross sections is relative; The top of described two dilator feet is provided with the opening regulating mechanism of two dilator feet of control folding, and is respectively equipped with the abduction governor motion of control dilator foot bottom openings of sizes at each dilator foot top.
The periphery of described dilator foot is coated with tubulose transparent rubber film.
Described abduction governor motion comprises the dilator foot bending plate that extends laterally and form in dilator foot top, and be provided with regulating arm at dilator foot bending plate upside, described regulating arm and dilator foot bending plate pass through the A chain connection near an end of dilator foot, and be connected by screw at regulating arm and the dilator foot bending plate end away from the dilator foot, and dilator foot bottom opening is increased or dwindle by tightening or loosening screw.
Described opening regulating mechanism comprise link to each other with two regulating arms respectively or with two integrated two linking arms of regulating arm, and between two linking arms by the B chain connection, and connect by adjusting bolt in the outer end of two linking arms.
Should assist the using method of dilator to be:
1. the opening actuator of auxiliary dilator system is closed, the abduction actuator is interior receives, dilator foot (outer wrapping tubulose transparent rubber film) closely is engaged in outside the working sheath of nerve endoscope in a tubular form, in company with the slowly close focus (hematoma or intraventricular tumor) of working sheath of nerve endoscope.
2. after entering hematoma (or ventricles of the brain), extract working sheath of nerve endoscope, will assist dilator to stay original position and also fix (or artificial fixing) with fixed system in addition;
3. adjust as required opening regulating mechanism, regulate the dilator openings of sizes.Coat respectively hyaline membrane on the two dilator feet, the congestion around can avoiding etc. overflows into service aisle and stains endoscope lens, thereby obtains the good visual field; And various apparatuses are accidentally injured the passage surrounding brain tissues can avoid operating the time; Pass through simultaneously hyaline membrane observable passage periphery situation in case accidental haemorrhage.2 ~ 3mm suction pump and nerve endoscope are placed in the auxiliary dilator, remove part pathological changes (hematoma or tumor) under the whole dilator;
4. adjust as required dilator foot abduction actuator, regulate dilator distal opening size.After removing the part pathological changes, intracranial pressure lowers relatively, has living space and adjusts the abduction actuator of dilator; And part pathological changes major part is removed under the whole dilator, removes peripheral pathological changes, needs to adjust dilator; Simultaneously in conjunction with the dissection of cerebral tissue, the cerebral tissue surface exists abundant blood vessel and important pericaryon, has the stronger arachnoidea of toughness and pia mater encephali on the surface of cerebral tissue and compliance is poor than the alba in deep.The dilator that adopts us to design by adjusting bottom one-sided or bilateral dilator foot, makes the bottom obtain larger operative space, simultaneously to the important blood vessels on brain surface, the damage that nerve is accomplished minimum level.
