Portable cardiovascular surgery cannula propeller for surgical department.

Abstract

The invention discloses a portable cardiovascular surgery cannula propeller for the surgical department. The propeller comprises a holding tube and a propelling tube; the propelling tube is located atthe left end of the holding tube; a same cannula body is inserted into inner sides of the holding tube and the propelling tube in a connected manner; a U-shaped limiting rod is fixed to each of the upper side and the lower side of the holding tube; a transverse insertion rod is movably inserted into the left end of each U-shaped limiting rod in a connected manner; the left end of each insertion rod is fixed to the propelling tube; each U-shaped limiting rod is provided with a locking piece for locking the corresponding insertion rod; the left end of the holding tube is rotatably provided withan internal gear ring in a sleeved manner; and the inner side of the internal gear ring is engaged with a plurality of driven gears. The propeller can automatically propel the cannula body, and has agood use effect; while the distance between the holding tube and the propelling tube can be adjusted as needed, so that the contact length between the propeller and the cannula body is larger, and propelling is more stable; and the whole propeller is small in size, convenient to carry and flexible and convenient to use.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a portable propeller for intubation in cardiovascular surgery. Background technique [0002] In heart or great vessel surgery, it is often necessary to insert surgical catheters in the human body, and these catheterization operations rely entirely on medical staff to insert the catheter into the surgical incision. This kind of manual operation has higher requirements on the operator, and it is difficult to grasp the stability and accuracy of the hand-held intubation tube. During the operation, the intubation tube is prone to be bent, which brings great trouble to the medical staff. Most of the existing surgical intubation propellers are simple in structure, and their propelling effect and stabilizing effect on intubation are not good enough, which affects the operation effect. Contents of the invention [0003] The purpose of the present invention is to solve the shortcoming...
