Double-rod pressure-increasing surgery cannula expander

Abstract

The present invention relates to a medical appliance, particularly to a double-rod pressure-increasing surgery cannula expander, which is composed of an inner expanding rod, a rod base, a pincer handle, a rivet, a sawtooth card and a handle, wherein, the striped pincer handle and the long axis of the elliptical annular handle generate an obtuse angle and are integrated. A pair of pincer handles and handles are connected through the rivet, and the inner side of each handle is provided with the sawtooth card integrated with the handle. The end of each pincer handle is provided with a rod seat which is vertical to the pincer handle and is integrated with the pincer handle. Then end of the rod seat is provided with the inner expanding rod integrated with the rod seat. The diameter of the inner expanding rod is one half of the rod seat, and the length is 2-3 times of the rod seat. The double-rod pressure-increasing surgery cannula expander not only can firmly fix the cannula, but also can send the cannula into the deeper part thereby greatly increasing the accuracy and stability of the surgery.

Description

Technical field [0001] The invention relates to a medical instrument, in particular to a double-rod expansion type surgical intubation expander. Background technique [0002] In heart or large blood vessel surgery, it is often necessary to intubate the blood vessel. In current operations, the tube is directly intubated with the hand. For deep operations, the hand cannot reach the deep part of the incision. At this time, because the tube is relatively soft and the hand-held part is far from the tip of the tube, the accuracy of the intubation is greatly affected. Summary of the invention [0003] In order to solve the shortcomings of the prior art, the present invention provides a double-rod expansion type surgical intubation expander capable of stably clamping the intubation. [0004] The solution to the technical problem of the present invention is that the double-rod expansion type surgical intubation expander is composed of an internal expansion rod, a rod seat, a forceps handle,...

AI Technical Summary

Problems solved by technology

[0002] In heart or great vessel surgery, it is often necessary to intubate the blood vessel. In the current operation, the tube is directly held by the hand for intubation. When performing deep operations, the hand cannot reach into the deep part of the incision.

At this time, because the tube is relatively soft, and the hand-held part is far away from the tip of the tube, the accuracy of intubation is greatly affected.
