Development of a New Irrigation Sucker for Microneurosurgery-Technical Note-

Abstract

A new irrigation sucker (Delta Irrigation Sucker  ) was designed for microneurosurgery. The Delta Irrigation Sucker  has a unique trigonal pyramid-shape thumb piece, providing a very stable grip. Irrigation is achieved easily by pushing a small button just behind the pressure-regulating pore. Stable hold of the sucker and easy handling of the irrigation button enable irrigation without unsteadiness of the sucker. The Delta Irrigation Sucker  is available in six sizes, with diameters from 1.5 mm to 4.0 mm at 0.5 mm intervals. Irrigation force is provided by a pressure bag, and a normal sterile transfusion set can be used as the irrigation circuit. The Delta Irrigation Sucker  was used in 20 cases of clipping for ruptured cerebral aneurysm, five cases of tumor resection, and three cases of anterior clinoidectomy and opening of the internal auditory meatus. Subarachnoid clot was easily removed and the bleeding points were easily confirmed. Irrigation, controlled by natural finger movement, did not cause unsteadiness of the sucker.

An Irrigation Suction System Using a Pressurized Fluid High-Flow Pump System in Comparison with a Standard Cuff Pressure System: Technical Note

“…[1][2][3][5][6][7]11 These include bipolar systems with pressurized IV fluid, techniques for positioning the irrigation fluid and the aspiration tube within the operative field for continuous irrigation and aspiration, 7 and devices that unify the IS system. [2][3][4] We performed surgery according to the principle of sharp dissection. 8 To use only as much irrigation fluid as necessary and only when necessary, we used an IS system that unified IS tubes.…”

“…8 To use only as much irrigation fluid as necessary and only when necessary, we used an IS system that unified IS tubes. Various examples of such systems are on the market, [1][2][3][5][6][7][8]10 and these are selected according to surgeon preferences. However, it is necessary to pressurize the IV irrigation fluid continuously and consistently in all these systems.…”

“…However, it is necessary to pressurize the IV irrigation fluid continuously and consistently in all these systems. [1][2][3][4][5] Using a syringe to drop fluid at the location indicated by the surgeon has traditionally been a major role for an assistant during surgery. However, although this is performed as a matter of course, there is no guarantee that a suitable volume of fluid will be applied at the moment intended by the surgeon.…”

“…1 Irrigation-suction (IS) systems are often used for this purpose, and pressure cuff devices are most frequently used to pressurize the fluid. [2][3][4] Various IS systems have been developed 1,3,5,6 and marketed for irrigation and suction of neurosurgical fields. Saline, Ringer lactate solution, and artificial cerebrospinal fluid are all used for irrigation.…”

“…Saline, Ringer lactate solution, and artificial cerebrospinal fluid are all used for irrigation. 3,4,7,8 Because irrigation fluid bags require pressure for use in IS systems, many institutions 3,9,10 use the compression pressure bag system that is normally used to measure arterial pressure. In the past, we also used this method, although manual compression pressure bags (►Fig.…”
