Abstract

The invention relates to the technical field of tools for biological surgery, and particularly relates to a novel linkage mechanism for a handheld ultrasonic cutter. The novel linkage mechanism comprises an outer shell, a forceps mouth mechanism, an ultrasonic vibration mechanism, a transmission mechanism, a linkage mechanism body and a handle, wherein the outer shell has a certain thickness; the forceps mouth mechanism is powered by ultrasonic waves and cuts tissue; the ultrasonic vibration mechanism is connected with a power supply and generates ultrasonic waves after being powered on; the transmission mechanism is connected with the forceps mouth mechanism and drives the forceps mouth mechanism to move; the linkage mechanism body is connected with the transmission mechanism and used for an operator to control the transmission mechanism to move; the handle is connected with the linkage mechanism body; the linkage mechanism body comprises a push cylinder, a force application rod and a linkage rod; the push cylinder bears the transmission mechanism and is connected with the force application rod through the linkage rod; the force application rod is of a bent arc structure and fixed to the inner side of the outer shell through a lever point; and when the force application rod is pushed, the force application rod is pushed. The novel linkage mechanism for the handheld ultrasonic cutter aims at overcoming the defects in the prior art, reduces the use space and has high practicability.

Description

technical field [0001] The invention relates to the technical field of biological surgery tools, in particular to a novel linkage mechanism for a hand-held ultrasonic cutter. Background technique [0002] Cutting devices are often used when performing surgery on organisms. The commonly used cutting device is a bipolar tissue closer; Connected, the electrode base is equipped with a high-frequency input plug. The bipolar tissue closer can perform more precise electrocoagulation and hemostasis on small blood vessels and other structures. The principle is that high-frequency current dissolves and denatures proteins. There is a differentiated zona pellucida, thereby producing permanent lumen closure to achieve hemostasis, and when the tissue denaturation and fusion are completed, the power can be automatically cut off. [0003] The double-lobe tweezers of the existing bipolar tissue closers have tweezers, and the tweezers are integrally formed with the double-lobe tweezers. The...
