Tumour collection chamber for space-occupying lesions in neurosurgery

Collection of tissue sample is one of the most important step in neurosurgery while removing intracranial or intraspinal space occupying lesions (SOL). It is required for tissue diagnosis, further treatment planning and prognostication. There is no mention of any tool except taking pieces using various biopsy/holding forceps or curettes. Author has designed a prototype of a tumour collection chamber (TCC), which is connected to the suction tubing for collection of solid tumours during surgical removal by suction by selectively allowing the suction flow through the TCC. It is easy to use as and when the tumour is being removed and suction flow can be bypassed by the surgeon or the assistant once tumour removal is done or otherwise.
