Embodiment Construction
[0013] The present invention will be further described below in conjunction with the drawings and embodiments.
[0014] Such as figure 1 , figure 2 As shown, the hand-operated surgical intubation pusher of the present invention includes a handle 1, a revolver 2 fixedly mounted on the upper end of the handle 1, and a revolver 3 is installed in the revolver 2 through a bearing. 3 is equipped with a rocking handle 4. When in use, one hand grasps the handle 1 to fix it, and the other hand drives the runner 3 to rotate through the crank 4.
[0015] Compression nuts 7 and 8 are inserted into the upper end of the runner bin 2, and the inner ends of the compression nuts 7 and 8 located in the runner bin 2 are connected with press rods 9 and 10 through threads. Rotate the compression nuts 7, 8, and the compression nuts 7, 8 and the compression rods 9, 10 can rotate relative to each other to adjust the distance between the two.
[0016] At least two pressure rods 9, 10 are respectively fixe...

The invention relates to cardiovascular surgery appliances and in particular relates to a hand-operated operation cannula propeller. The hand-operated operation cannula propeller comprises a handle, and a runner bin which is fixedly arranged at the upper end of the handle, wherein a runner is arranged in the runner bin through a bearing; an operating crank is arranged on the runner; a pressing nut is inserted into the upper end of the runner bin; the inner end of the pressing nut positioned in the runner bin is connected with pressing rods through threads; at least two pressing rods are respectively and fixedly connected to two ends of a pressing plate; a pressing wheel is arranged on the pressing plate; a guiding catheter is arranged between the pressing plate and the runner and is mounted on the bin wall of the runner bin; and the axis of the guiding catheter is positioned on the tangent line of the runner. The operation cannula propeller is hand-operated and propelled by adopting the runner, the defects such as instability and low accuracy brought by manual operation are overcome, the operation cannula propeller is simple in structure and convenient to use, and the operating stability and accuracy are greatly improved.
Description
Technical field [0001] The invention relates to a cardiovascular surgical instrument, in particular to a hand-operated surgical intubation pusher. Background technique [0002] In heart or large blood vessel surgery, it is often necessary to insert surgical catheters into the human body. These intubation operations completely rely on medical staff to hold the cannula and insert it into the surgical incision. This kind of manual operation has high requirements for operators, and the stability and accuracy of the handheld intubation tube are difficult to grasp. Chinese patent 2012102651582 discloses a "Cardiovascular Surgery Intubation Fixing Clip", which can be used to clamp the end of the intubation tube during the operation, and the operation of the holding fixture during the intubation process can improve the intubation operation to a certain extent Accuracy and stability. However, the fixed clip can only play the role of fixing the intubation tube and facilitating the hand-h...
