Abstract

The invention discloses an ultrasonic knife head for laparoscopic surgery, and belongs to the technical field of ultrasonic knifes. The ultrasonic knife head comprises a knife body, wherein a metal sheath is arranged at one end of the knife body, a knife point is arranged at one end of the metal sheath, a rubber air pipe is arranged at the upper end of the knife body, and a grip is arranged at thelower end of the knife body. By mounting the corresponding grip according to use requirements, inserting the grip into the lower end of the knife body and clamping pin bodies into fixing holes, underthe action of elastic force of reset springs, the pin bodies are always clamped into the fixing holes, so that the grip is fixed and prevented from falling off; during replacement, the grip is rapidly taken down after the pin bodies pressed into the grip; and by replacing grips of different sizes, comfortable gripping gesture is provided, and long-time gripping is facilitated. By rotating and adjusting a rotating sliding base to slide along an annular sliding rail and driving the rubber air pipe by a fixing cylinder to change the angle, the rubber air pipe is prevented from being blocked whenheld by hand, and operation and use are facilitated.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic knife, in particular to an ultrasonic knife head for laparoscopic surgery. Background technique [0002] Ultrasound generally refers to high-intensity focused ultrasound therapy. High-intensity focused ultrasound therapy is a new type of tumor treatment. When using this method to treat tumors, ultrasonic positioning can be used, high-intensity ultrasonic waves can be used to kill tumor cells in the target area without damaging the surrounding normal tissues, and the thermal effect of ultrasonic waves at the focus can form a high temperature above 60°C in the target area, resulting in protein Degeneration and coagulation necrosis of tissue cells or irreversible severe damage, so as to achieve the purpose of treating tumors. [0003] The prior art has the following problems: the existing ultrasonic cutter head for laparoscopic surgery has a fixed handle size during use, which cannot be replaced...
