Abstract
The utility model discloses a ventricle endoscope sheath belonging to medical device, which consists of a sheath and a core. The cylindrical core is nested in the sheath, and the right end of the sheath has a convex ring extending outward. The left end of the core is of ball shape matched with the left arc end of the sheath, and the right end of the core is provided with a baffle ring and a handle, and both the sheath and the core are made of transparent colorless material. Compared with the prior art, the ventricle endoscope sheath of the utility model has the advantages of reasonable design, simple structure, convenient use, high transparency, enlarged visual range of the ventriculoscope, easy disinfection, convenient operative conditions for medical staffs and no hurt, thus the utility model has very good extension and application value.
Description
1, technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of intraventricular endoscope epitheca.
2, background technology
Using intraventricular endoscope at present can be undertaken than complicated operations by the method for microtrauma, application in neurosurgery more and more widely, but present intraventricular endoscope epitheca is the cylinder of a metal, the interface that two belt switches are arranged on the one end, be used for respectively washing by water and attracting flushing water, one cylinder inner core is arranged in the cylinder, its complex structure, complex operation, freshly hemorrhagely very fast preceding end mirror is stuck with paste, be unable to recognize in the visual field anything, and the depth under the endoscope also can't confirm, is difficult to the overall picture that observation post needs operative site, thereby brings bigger difficulty to operation, the end is set to pyramidal structure in addition, can cause wound to the cerebral tissue structure, at present, good solution not arranged also.
3, summary of the invention
Technical assignment of the present utility model is to provide a kind of intraventricular endoscope epitheca at above-mentioned deficiency of the prior art, and that this intraventricular endoscope epitheca has is reasonable in design, simple in structure, easy to use, transparency is high, be easy to sterilization, AT characteristics.
The technical scheme that its technical problem that solves this utility model adopts is: be made up of epitheca and inner core, cylinder core is sleeved in the epitheca, the bulge loop that stretch oriented outer, the right part of epitheca, the left end of inner core is a spheroidal, the left end of epitheca is that arc matches with the spheroidal of inner core left end, the right-hand member of inner core is provided with baffle ring and handle, and epitheca and inner core are colourless transparent material and make.
Epitheca is provided with scale.
Handle is circular.
Intraventricular endoscope epitheca of the present utility model is compared with prior art, has following outstanding beneficial effect: reasonable in design, simple in structure, easy to use, transparency is high, enlarged the brain visor visual range, be easy to sterilization, be convenient to characteristics such as medical personnel's operation technique, no wound.

5, the specific embodiment
Explain below with reference to Figure of description intraventricular endoscope epitheca of the present utility model being done.
Intraventricular endoscope epitheca of the present utility model, its structure is made up of epitheca 1 and inner core 2, cylinder core 2 is sleeved in the epitheca 1, the bulge loop 3 that stretch oriented outer, the right part of epitheca 1, the left end of inner core 2 is a spheroidal 4, the left end of epitheca 1 is that arc matches with the spheroidal 4 of inner core left end, and the right-hand member of inner core 2 is provided with baffle ring 7 and handle 5, and epitheca 1 and inner core 2 are colourless transparent material and make.
Epitheca 1 is provided with scale 6.
Intraventricular endoscope epitheca of the present utility model in use, to puncture before art inner core and epitheca separately immerses in the disinfectant solution standby, after during operation cerebral tissue being exposed, the cortex of fulgerizing hemostasis, inner core is inserted spheroidal one end that makes inner core in the epitheca expose epitheca, after the arc of epitheca left end matches, and insert in the cerebral tissue together, extract inner core after arriving the target area, ventricularendoscope is put into epitheca, and the operation that can undergo surgery can be seen the scale that is engraved on the outer wall from the epitheca inwall in operation, thereby guaranteed the correct judgement on the degree of depth, so that it is accurate to perform the operation.
Except that the described technical characterictic of description, be the known technology of those skilled in the art.
Claims (3)
1. intraventricular endoscope epitheca, comprise epitheca and inner core, it is characterized in that cylinder core is sleeved in the epitheca, the bulge loop that stretch oriented outer, the right part of epitheca, the left end of inner core is a spheroidal, the left end of epitheca is that arc matches with the spheroidal of inner core left end, and the right-hand member of inner core is provided with baffle ring and handle, and epitheca and inner core are colourless transparent material and make.
