The invention discloses an anti-slip endoscopic puncture device, which comprises a puncture sleeve, a rod cap and an anti-slip mechanism. The surface of the puncture sleeve is inlaid and fixed with an annular thread, and the rod cap penetrates through a puncture rod through the sleeve seat and the anti-slip mechanism. The puncture sleeve, the fixed anti-slip mechanism is movably installed on the top of the rod cap, and the fixed anti-slip mechanism includes a connecting plate, a mounting groove, an engaging groove, a T-shaped block, a connecting sleeve, a first connecting hole, an arc plate, a first The connecting column, the second connecting hole, the rotating screw, the concave block, the second connecting column, the third connecting hole, the clamping plate, the threaded hole, the anti-slip pad, the threaded rod and the limit plate, and the bottom of the connecting plate is provided with an installation groove, A T-shaped block is fixed inside the installation groove, the concave block is engaged with the T-shaped block, the limiting plate is engaged with the engaging groove, and the anti-slip endoscopic puncturer is provided with an annular thread. The resistance of the puncture cannula to be pulled out of the skin is increased through the annular thread while reducing the resistance of the puncture cannula to puncture the skin.
Description
technical field [0001] The invention relates to the technical field of trocars, in particular to an endoscope trocar with anti-fall. Background technique [0002] Laparoscopic surgery mainly relies on a medical endoscope to image the surgical area on a TV screen by means of a camera system, and perform surgery by watching TV images. During laparoscopic surgery, it is necessary to puncture the human body to form an instrument channel. The doctor uses a puncture device. It is necessary to grasp the handle and apply downward force, so that the puncture rod penetrates the puncture cannula and enters the inside of the human body. Since the palm is operated with gloves, a certain degree of mucus is attached to the surface of the gloves, and then the handle is held again through the gloves. At this time, the handle slips on the ground due to the sliding friction between the mucus on the surface of the glove and the glove, causing dust on the surface of the puncture rod, which canno...
