Evaluation of an aspiration-type semiautomatic cutting biopsy needle
2015
AbstractPurpose: The purpose of this study was to evaluate an aspiration-type semiautomatic cutting biopsy needle for biopsy of bovine tissue. Material and methods: Aspiration-type semiautomatic cutting biopsy needles (18 gauge × 160 mm) with aspiration (Group A), aspiration-type semiautomatic biopsy needles without aspiration (Group Wo), or normal-type semiautomatic biopsy needles (18 gauge × 150 mm) (Group N) were used in 10 biopsies each of bovine liver or lung. The specimens were weighed with an electronic balance. Results: Mean (standard deviation) weights for bovine liver specimens in Groups A, Wo, and N were 6.80 (0.615) mg, 5.62 (0.843) mg, and 4.19 (0.140) mg, respectively. Mean weights of bovine lung specimens from Groups A, Wo, and N were 2.98 (0.828) mg, 2.67 (0.832) mg, and 1.94 (0.864) mg, respectively. A significant difference was seen between the 3 groups for bovine liver. However, a significant difference was only seen between Groups A and N for bovine lung. Conclusion: Bovine liver and l...
