Automatic sealing switching-free mechanism of puncture outfit

Abstract

The invention provides an automatic sealing switching-free mechanism of a puncture outfit. The automatic sealing switching-free mechanism is mainly composed of a bracket assembly and a puncture casingpipe assembly. When a clinic operative instrument enters a puncture casing pipe, the instruction is firstly in contact with a protective gasket, the damage of the operative instrument to a protectivesealing valve is effectively avoided, and the sealing valve and the protective gasket are formed by two or more pieces in an annular assembly mode. When the clinic operative instrument enters the puncture casing pipe, the sealing valve can effectively seal the periphery of the operative instrument according to the appearances of different operative instruments and provide good air impermeabilityfor a clinic operation, the bracket assembly and the puncture casing pipe assembly can be separated at any time through a designed fastener and a connecting switch, and a clinic doctor can conveniently take out the lesion tissue through the puncture casing pipe and meanwhile does not need to replace adapters different in diameter when using different diameters of operative instrument. Therefore, the operation time of the clinic doctor is greatly shortened, and the operation safety is greatly improved.

Description

technical field [0001] The invention specifically relates to an automatic sealing and conversion-free mechanism of a puncture device, which belongs to the technical field of medical devices. Background technique [0002] An automatic sealing and conversion-free mechanism of a puncture device is mainly suitable for clinical surgery to puncture the abdominal cavity during laparoscopic surgery, transport gas to the abdominal cavity, and establish a passage for the endoscope and surgical instruments to enter and exit the abdominal cavity from the outside. It is not only suitable for pneumoperitoneum surgery and minimally invasive laparoscopic surgery with pneumoperitoneum requirements, but also for minimally invasive incision surgery without pneumoperitoneum. In laparoscopic surgery, since the internal organs of the human body are mainly concentrated in the abdomen, in order to ensure the safety of minimally invasive surgery, it is necessary to ensure that the clinician has a go...

Problems solved by technology

In laparoscopic surgery, since the internal organs of the human body are mainly concentrated in the abdomen, in order to ensure the safety of minimally invasive surgery, it is necessary to ensure that the clinician has a good surgical field of view, so it is necessary to inject gas into the patient's body to expand the patient's abdomen, so There are high requirements on the airtightness of the trocar; at the same time, in laparoscopic surgery, clinicians need to use surgical instruments of different diameters, which puts forward higher requirements on the airtightness of the trocar. The puncture device used in laparoscopic surgery, in order to meet the requirements of better air tightness for surgical instruments of different diameters, a circular converter with different diameters is added to the upper end of the puncture device to ensure that the puncture device can en
