Visual puncture outfit convenient for fixing air delivery pipe

Abstract

The invention discloses a visual puncture outfit convenient for fixing an air delivery pipe, which comprises a sealing piece, a clamping mechanism and a movable ring, wherein a sleeve is connected to the bottom of the sealing piece in a buckled mode, a puncture cone is slidably connected to the interior of the sleeve, a C-shaped frame is fixed to the outer side of a mounting ring, a second bolt is connected to the top of the C-shaped frame in a threaded mode, the movable ring is slidably connected to the outer side of the sleeve, a fixed block is fixed to the outer side of the movable ring, and the fixed block is in threaded connection with a third bolt. The visual puncture outfit convenient for fixing the air delivery pipe is provided with the second bolt, trapezoidal blocks and a first spring, and the second bolt at the top of the C-shaped frame is rotated to drive the conical block to drive the two sets of trapezoidal blocks and two sets of clamping blocks below to move oppositely, so that the air delivery pipe is conveniently sleeved on the connecting pipe on the outer side of the sealing piece, and then two sets of connecting rods and clamping blocks are driven to move oppositely under the elastic action of the first spring to clamp the air delivery pipe on the outer side of the connecting pipe, so that the air delivery pipe is conveniently fixed and prevented from falling off.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a visible puncture device for fixing air tubes. Background technique [0002] The trocar is a medical device that provides instrument channels for minimally invasive abdominal and pelvic surgery. Compared with the traditional abdominal puncture device, the visual puncture device can display the puncture process in real time, which greatly improves the convenience and effectiveness of the puncture operation. The inner wall of the abdominal cavity is separated from the viscera, so as to facilitate the operation. The existing puncture device usually puts the air delivery tube with the same size as the connecting tube on the puncture device directly on the outside of the connecting tube to inject gas into the patient's abdominal cavity. This method has a poor fixation effect on the tracheal tube, and it is easy to cause the tracheal tube to fall off due to the influence of...

Problems solved by technology

[0003] The purpose of the present invention is to provide a visual puncture device that is convenient for fixing the tracheal tube, so as to solve the problem that the existing puncture device proposed in the above-mentioned background technology usually puts the tracheal tube directly on the outside of the connecting tube to the patient's abdominal cavity when in use. Gas injection, the fixation effect is poor, and because the gas delivery tube is long, when adjusting the angle of the puncture device, it will cause the gas delivery tube to fall and shake, and the practicability is poor
