PUNCTURE SYSTEM AND CONTROL HANDLE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/125226
Kind Code:
A1
Abstract:
A puncture system (800) and a control handle (3, 4, 5, 6, 7) thereof. The control handle (3, 4, 5, 6, 7) comprises a shell (41, 51, 61, 71) and a control mechanism (44, 540, 640). The shell (41,51,61, 71) has an accommodation space (410) therein; and the control mechanism (44, 540, 640) comprises an operation member (441, 541, 641, 741) provided on the shell (41, 51, 61, 71) and a control switch (440) provided in the accommodation space (410). In this way, by means of operating the operation member (441, 541, 641, 741), the control switch (440) may be switched between on and off states. In the on state, a closed circuit is formed between an electrode tip (1) and external energy, and in the off state, an open circuit is formed between the electrode tip (1) and the external energy, so that an operator may realize the on-off of the circuit by means of operating the operation member (441, 541, 641, 741), which is very convenient and facilitates an increase in the probability of successful puncture.
