Description
Technical Field
The invention relates to a suction apparatus in medical apparatus, in particular to a minimally invasive steering soft suction apparatus.
Background
The suction apparatus is needed to remove the blood vessel broken ends of hematocele, effusion, necrotic tissue, tumor tissue and hemorrhage in the surgical operations of neurosurgery, otorhinolaryngology and the like. The aspirator has the functions of sucking liquid, semi-solid, blood vessel, tumor and other matters in operation, cleaning operation and exposing bleeding part. The suction apparatus is based on the principle that the removable target substance is sucked into the pipeline through pressure difference, and the operation is removed; or the target tissue is absorbed to control the spatial position of the target tissue. The aspirator can maintain a clean operation environment for an operator, and can adsorb and control the spatial positions of certain target blood vessels, tissues, tumors and the like; assisting the surgeon in completing the target action. In department operations such as neurosurgery and otorhinolaryngology, an aspirator is an indispensable conventional surgical instrument. With the development of science and technology and the improvement of medical technology level, microscopes and endoscopes are widely popularized in various neurosurgery operations, which continuously puts forward new requirements on suction devices in departments such as neurosurgery, otorhinolaryngology and the like.
The surgeons in departments of neurosurgery, otorhinolaryngology and the like find that the prior suction apparatus has the following defects in long-term operation experience: (1) in the neurosurgery operation, some dead zones and corners exist, the traditional hard aspirator cannot be effectively operated, or the hard aspirator with the front end having different angles is frequently replaced. (2) In most neuroendoscopy and microscope operation, in order to reach a target area, a channel, a rigid suction apparatus and an endoscope need to be adjusted, which puts high requirements on the coordination of two-hand operation and three-hand operation. The first solution is to use a pneumatic arm, which is expensive and not popular. The second method is to strengthen the preoperative operation training and match the training, which consumes a great deal of valuable time of surgeons and has higher labor cost. In most neuroendoscopy operations, the target action can be met after the far end of the channel tube is repeatedly adjusted for multiple times, so that multiple times of physical traction, extrusion and contusion are formed on deep brain tissues, nerves, blood vessels and the like, the risks of operation injury in the operation, hemorrhage in the perioperative period, cerebral edema and the like are increased, and the operation injury counteracts partial operation benefits. Fourth, if the endoscope channel is curved like an arc-shaped guider, the existing suction apparatus and other tools cannot be used. These problems are troubling surgeons in departments such as neurosurgery, otorhinolaryngology and the like, and a new minimally invasive diversion soft aspirator is urgently needed to solve the problems.
