Description
Technical Field
the utility model belongs to the technical field of medical instrument, a neural endoscope is with supplementary mirror suction device that holds is related to.
background
The neuroendoscopy operation has small wound, can place a light source near an operation area, has good illumination effect, does not need to focus repeatedly, has high image resolution in the operation, can carry out panoramic and close-range observation, can carry out high-definition observation on surrounding anatomical structures, and is favorable for distinguishing the boundary between lesion and normal tissue structure (the neuroendoscopy technical clinical application experts consensus writing group, the neuroendoscopy operation technology treatment ventricular and cerebral cavity system diseases Chinese experts consensus J, China neuro-surgical journal 2016, 32(8):757-766.DOI: 10.3760/cma.j.issn.1001-2346.2016.08.001.). Currently, neuroendoscopy is rapidly developed in neurosurgery, and is widely used and approved not only in the treatment of traditional ventricular and cranial base diseases, but also in a variety of neurosurgical fields, such as various cerebral hemorrhages including hematoma in brain parenchyma (Chenghe, Von triphase, Korean shiguang, etc.; curative effect analysis for removing hypertension basal ganglia hemorrhage by frontal access neuroendoscopy [ J ]. Hebei medicine, 2018, 40(21): 3292. along with 3295.

Meta analysis of the efficacy of craniotomy optic nerve decompression and endoscopic optic nerve decompression [ J ]. China journal of modern medicine, 2018,28(27):64-70.DOI: 10.3969/j.issn.1005-8982.2018.27.012 ], etc.
The working conditions of the endoscope require the presence of an operating channel and a cavity, the channel being used for the passage of the endoscope therethrough. The lacunae may occur naturally or may be a result of disease or surgery. The lacunae requires sufficient space to allow the endoscope to view the surrounding structures and to perform the surgical procedure within it safely and efficiently (Neuroendoscopic clinical practice experts group consensus J.Chinese experts group for neuroendoscopic surgical techniques in the treatment of ventricular brain systems diseases [ J ]. J.Zhonghua J.Neurosurgical, 2016, 32(8):757-766.DOI: 10.3760/cma.j.issn.1001-2346.2016.08.001.). The existing mainstream method is that an operator and an assistant are matched with two-person four-hand operation, the assistant holds the endoscope and washes the endoscope, and the operator holds an instrument for operation. The operation mode requires that the operator and the assistant have enough professional knowledge and under-mirror training at the same time, and the close cooperation is achieved, so that the operation can be perfectly carried out.
The technical development is a process from simple to complex and complex to simple, and in order to improve the operation efficiency and avoid unnecessary injuries, some foreign professors currently try to use a single hand to hold an endoscope and an aspirator simultaneously, which is called as a chopstick technology vividly. The technology theoretically needs no assistant for cooperation, and the operation can be perfectly carried out by a single person, so that the operation risk caused by the matching error is greatly reduced; however, the difficulty of the technique is far better than that of using chopsticks, one hand needs to keep the stability of holding the endoscope, and meanwhile, the technique has the flexibility of the suction apparatus, and the suction apparatus can be matched with an apparatus of the other hand to operate according to the conditions in the operation at any time. Since most neurosurgeons are right handed, the use of left-handed scopes and right-handed instruments is limited by the high requirement for left-handed dexterity.
Most of the existing endoscopes and suction apparatuses are separated, two instruments are required to be held by a single hand, and the difficulty is high. If the endoscope and the suction apparatus are simply fixed, the endoscope and the suction apparatus are not easy to move, and the flexibility is greatly insufficient. If the endoscope with the controllable suction channel is redesigned, the cost of updating the equipment is huge.
