Abstract
The invention discloses a thoracic and abdominal puncture knife, and belongs the technical field of medical apparatuses. The puncture knife comprises a knife rod body and a knife head which is integrally arranged at one end of the knife rod body and is identical to the knife rod body in diameter, and a knife edge is constituted on the knife head; the puncture knife is characterized in that an easy-to-bend transition section is constituted between the knife rod body and the knife head; and the diameter of the easy-to-bend transition section is 1/3-1/5 of the diameter of the knife rod body. Angle requirements of doctors, who implement a puncture operation on a patient in clinical, can be satisfied by bending the knife head having the knife edge relative to the knife rod body as required; theoperation can be facilitated, and operating difficulty of the operating doctors can be reduced and puncture efficiency can be improved; and materials can be saved; therefore, the puncture knife is consistent with the spirit of economizing and energy-saving economy which is advocated by the whole society at present.
