“…Although a study reported that the threshold value for a safe negative pressure of dog brain tissue was approximately 15 kPa, it could not represent the ideal negative pressure for different structures of the human brain ( 5 ). On the other hand, the negative pressure at the suction tip cannot be predictable and is variable, depending on the air inlet and the load on the central vacuum system.…”

BackgroundAn essential surgical tool in neurosurgery is the suction tube. The skillful and accurate use of a suction tube facilitates the neurosurgical operation.ObjectiveThis study is to verify the practicality of an adjustable pressure suction tube (APS tube) and to explore the ideal APS tube diameter and tip negative pressure for different intracranial structures.MethodsAPS tubes were used to aspirate brain tissues and carotid arteries of rats. Laser speckle contrast imaging (LSCI) was used to record the blood flow velocity (BFV). We measured APS tube diameter, air inlet size, tip negative pressure and central negative pressure and calculated the correlation between them. In our department, intraoperative real-time parameters including APS tube diameter, length, air inlet size, and central negative pressure were recorded, and the tube tip negative pressure suitable for different intracranial structures and parts was calculated.ResultsAll experiments were carried out using APS tubes. Experiments on rats objectively reflected a severe structural damage to the brain and blood vessels by the suction tube, which might even result in an irreversible reduction in blood flow., Rat carotid arteries and brain tissue suffered severe damage when the tip negative pressure exceeded 33.4 ± 1.8 and 29.2 ± 2.0 kPa, respectively. BFV failed to return to the preoperative level 3 min after the operation (p < 0.05), and this decrease was more pronounced when the suction tube diameter was large (p < 0.05). The tip negative pressure was positively and negatively correlated with central negative pressure and the air inlet size, and was independent of APS tube diameter. A total of 50 operations including 39 tumor resection operations and 11 moyamoya disease bypass operations were recorded. Large-diameter APS tubes (3.5 mm) with an closed air inlet were frequently used to maintain a greater tip negative pressure before the incision of dura mater. When important structures such as motor cortex and brainstem were involved, 1.5- or 2.0-mm-diameter APS tubes were mostly used, and an air inlet was opened up to 0.7–2.1 mm to maintain a safe tip negative pressure (7.4–27.9 kPa).ConclusionAPS tubes with a mechanical knob provide stable and precise adjustment of the tip negative pressure, avoiding excessive negative pressure that causes serious damage to the intracranial structure. And, this allows the surgeon to hold the suction tube more freely and operate at any angle with an appropriate fulcrum near the incision to achieve efficient atraumatic suction and enhance surgical safety.

“…This tool has two main functions: (A) aspiration, which is either the non-traumatic removal of blood and fluid or the removal of soft tissue [8,9], and (B) tissue holding [5]. Surgical aspirators are included in commercial simulators but studies on their mechanical behavior are scarce in the literature and do not provide enough experimental data to develop a model suitable for a simulator [10,11,12,13,14,15,16,17].…”

Suction in neurosurgery

Abstract: Conventional suction systems for neurosurgery are assessed against the background of findings in experimental investigations. Criteria for optimum suction are proposed. The advantages of a modified suction system for neurosurgery are discussed, and recommendations are given.
