Embodiment Construction

[0025] Figure 1A to Figure 1C Shown is an HF electrode handle 1 for operating an HF electrode (not shown) for HF surgery, comprising a movable switch control module 3 having a housing 3a, the The housing 3a has a hook 3b embedded therein and two buttons 5 as actuating elements for each on / off switch 7 used in the housing 3a. The switch is used to switch between the various (electrical) operating modes of the instrument. Instead of one or two switches, rotary or sliding actuators for controlling electrical operating parameters of the instrument can be provided.

[0026] Each switch 7 has annular inner and outer contacts 7a, 7b. An inclined surface section 1a is provided on the operating part 1, which is used to install the switch control module 3, and there is a first groove 1b and a second groove 1c in this section, and the first groove 1b can accommodate the switch 7 And the second groove 1c cooperates with the hook 3b on the switch control module as a fixing or locking me...

Abstract

Disclosed is a switching control device for a medical instrument, especially for an electrode used in HF surgery, comprising a connection line. Said switching control device is designed as a switching control module for controlling various electrical operating modes of the instrument and includes a three-dimensionally and pressure-tightly sealed housing that is resistant to sterilization temperatures, an actuating element and fixing means to be releasably mounted within or on a manipulating part of the instrument, and module contacting means for interacting with device or instrument contacting means which are connected to the connection line in order to perform a switching control function.

Description

technical field [0001] The present invention relates to a switch control device for medical instruments, in particular, an electrode for HF surgery, and operating parts of such instruments. Background technique [0002] Here, the term "switching control device" means that the operator can switch or control the functions of the device in question (in particular the power supply to the device, the geometry of the device or from the Any switch and / or control device for signal transmission of instruments). In principle, "device" should be understood to mean any medical-surgical therapeutic or diagnostic-apparatus, while "operating part" means a part or part of such a device, which is held in the hand of the operator when the device is used for medical purposes and / or on which he performs a switch or control function. Endoscopic instruments without operating parts in the narrow sense but which can be operated and switched / controlled by an operator are expressly considered to be...
