Puncture device

Abstract

The invention discloses a puncture device. The puncture device includes a puncture device body, a puncture state sensing unit arranged in the puncture device body, a control unit, a prompt unit and apower source; the control unit includes a switch unit, and the power source, the switch unit and the prompt unit constitute a loop; the puncture state sensing unit is used for sensing the puncture state of the puncture device body, and the end, used for outputting an electric signal corresponding to the puncture state, of the puncture state sensing unit is electrically connected to a control end of the switch unit; an input end or output end of the switch unit is electrically connected to the prompt unit and used for controlling the switch states of the switch unit according to the electric signal, wherein the switch states include the switch-on state and the switch-off state; the power source is electrically connected to the puncture state sensing unit and the prompt unit separately and used for supplying power to the puncture state sensing unit and the prompt unit. According to the puncture device provided in the embodiment, the puncture state sensing unit is utilized to automatically judge whether or not the puncture device penetrates through the wall of an abdominal cavity during puncture, doctors are helped to make judgement, and the accuracy and safety of surgery can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of medical devices, in particular to a trocar. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive surgery, which has the advantages of small surgical incision and low harm to patients. To perform laparoscopic surgery, it is necessary to establish the connection between the extra-abdominal cavity and the intra-abdominal cavity. The puncture device is an indispensable consumable for endoscopic system surgery and minimally invasive medical treatment. gas, and to establish passage for endoscopes and surgical instruments from the outside world into and out of the abdominal cavity. [0003] However, during the actual operation, the surgeon needs to judge the depth of the puncture and whether it penetrates the abdominal wall based on experience. For inexperienced doctors, it is easy to cause deviation due to misjudgment, resulting in too deep punct...
