Self-destruction type device for limiting using times and on disposable electrosurgical pencil

Abstract

The invention provides a self-destruction type device for limiting using times and on a disposable electrosurgical pencil. The self-destruction type device for limiting the using times comprises a self-destruction groove (8), an ejector rod (2), a sleeve (7) and a switch (10). The upper end of the ejector rod (2) extends out of the self-destruction groove (8), and the lower end of the ejector rod (2) is inserted into the sleeve (7) in a sliding mode. A spring (9) is arranged in the sleeve (7), and when sliding, the ejector rod (2) compresses the spring (9). The switch (10) is composed of a contact A and a contact B, wherein the bottom end of the ejector rod (2) contacts the contact A, the contact A is connected with a plug pin (1) of a plug (12) in a conducting mode through a connecting wire, a connecting wire of the contact B is used as a power connecting wire, and connecting wires of the other two plug pins are respectively used as an electro-coagulation connecting wire (4) and an electro-scission connecting wire (5). The self-destruction groove (8) is sealed through a self-destruction partition piece (11), and the ejector rod (2) enables the self-destruction partition piece (11) to break under the action of pressure. The self-destruction type device for limiting the using times and on the disposable electrosurgical pencil ensures that the disposable electrosurgical pencil is in the real sense of 'being disposable' under the condition that the using habit of a doctor is not changed, and therefore safety of a patient is protected.

Description

technical field [0001] The invention relates to a high-frequency electrosurgical instrument, in particular to a self-destruction type time-limiting device that limits the use of a one-time use electric knife pen. Background technique [0002] The electric knife pen is used as the operating handle and is the main accessory of the high-frequency electric knife (a surgical device that uses the thermal effect of high-frequency current to complete cutting and coagulation). Now widely available as a one-time accessory. Disposable electric knife pen can effectively prevent cross infection. [0003] However, due to the restriction of consumer water products and the drive of profit, in actual clinical use, it is difficult for the disposable electrosurgical pen to be used "one-time". However, limited by cost and hygienic conditions, it is impossible to use disposable electrosurgical pens repeatedly safely and reliably, which will bring hidden dangers that should not happen to electr...
