Evaluation of the clinical usage of the basket-shaped biopsy microseparator

This experimental study was aimed to assess the use of basket shaped biopsy microseparator. In this study, it was aimed to evaluate the protection of brain tissue during neurosurgery of the brain tissue, clinical usage, and suitability.

Thirty cadaveric cow brains were used in this experimental feasibility study. Experimental materials were divided into two groups: In Group I, the microsurgical separation of the intrinsic brain parenchyma was performed by using the retraction of microsurgical basket separator. In Group II, the same microsurgical dissections were performed without microsurgical basket separator. The difficulty and suitability of the procedure was divided as three degree: very easy, easy, and difficult.

In Group I (n = 30), 20% fresh cadaveric cow brains, the difficulty of the dissection was evaluated as difficult; 60% of the brains were dissected with easy procedure. The remaining 20% of the brain dissection was evaluated as very easy. In Group II (n = 30), 40% fresh cadaveric cow brains, the difficulty of the dissection was evaluated as difficult; 53.33% of the brains were dissected with easy procedure. The remaining 6.67% of the brains were evaluated as very easy. The significance level was set at a P value of <0.046 in all statistical analyses.

This study showed that easily performing biopsy procedure and protecting the brain tissue with using of biopsy basket microseparator are feasible. It is thought that this instrument may make a contribution to the practical microsurgery in the protecting brain tissue and adequately performing of biopsy.
