Description
Technical Field
The utility model relates to a ventriculoscope work external member.
Background
When the ventriculoscope works, a transparent sheath is required to be arranged on the head of a patient so as to facilitate the observation of a probe; the existing ventriculoscope working kit comprises a transparent sheath and a solid puncture needle, wherein the solid puncture needle firstly punctures the scalp and other parts, then the sheath is sheathed and the scalp is placed, and then the solid puncture needle is drawn out; because the sheath and the solid puncture needle are both rigid, the brain tissue is greatly damaged in the puncture and implantation processes, and the liquid is difficult to remove and decompress, so that the observation is influenced; and the solid puncture needle can only be provided with a sheath with one diameter, so the use is inconvenient.
Disclosure of Invention
The utility model aims at the above-mentioned not enough of prior art, provide a ventriculoscope work external member, it has the advantage little to the brain tissue damage to but flowing back decompression guarantees the observation effect of ventriculoscope, and convenient to use.
In order to achieve the purpose, the ventriculoscope working kit of the utility model comprises a transparent outer sheath and a solid puncture needle, and is characterized in that the solid puncture needle is sleeved with a hollow puncture needle, the front end of the hollow puncture needle is connected with the front end of a cylindrical outer capsule, the hollow puncture needle is positioned in the outer capsule, and the rear end of the outer capsule is connected with a liquid outlet of a pressure control valve; the pressure control valve comprises a main valve body provided with a liquid inlet and a liquid outlet, and a pressure regulating pipe communicated with the main valve body, wherein the bottom of the pressure regulating pipe is closed, an adjusting screw is connected through threads and penetrates through the bottom of the pressure regulating pipe, a stop block, a spring and a valve core are sequentially arranged in the pressure regulating pipe in front of the adjusting screw in a sliding manner, and an overflow outlet is arranged in the middle of the pressure regulating pipe; the inner diameter of the outer sheath is larger than the outer diameter of the outer bag;
when in use, after the solid puncture needle and the hollow puncture needle are successfully punctured at the puncture point, if liquid needs to be discharged, the solid puncture needle can be pulled out and discharged through the hollow puncture needle; then slowly injecting liquid into the outer bag through a pressure control valve to enable the outer bag to expand into a prefabricated cylinder shape, controlling the filling pressure to be not more than a preset value through a valve core, and otherwise, discharging the liquid through an overflow outlet; gradually sheathing a transparent sheath outside the outer capsule, and then pulling out the solid puncture needle, the hollow puncture needle and the outer capsule;
in the puncture process of the utility model, the outer capsule wraps the hollow puncture needle, the damage to the brain tissue is small, the pressure and the speed of the outer capsule in the expansion process are controllable, and the damage to the brain tissue is also reduced; after the puncture is successful, the liquid can be discharged and decompressed, the observation effect of the ventriculoscope is ensured, and the same solid puncture needle is provided with the external capsules with different sizes, so that the use is convenient;
as a further improvement of the utility model, the rear end of the sheath is fixedly connected with an annular end disc; the operation and the depth positioning of the sheath are convenient;
as a further improvement of the utility model, a pressure gauge is arranged on the main valve body; perfusion pressure can be monitored;
to sum up, the utility model has the advantages of to brain tissue damage is little to but flowing back decompression guarantees the observation effect of ventriculoscope, and convenient to use.
