It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

Embodiments of the present application provide a surgical opening device, and in particular, an opening knife for opening a tissue (e.g., heart, etc.).

Referring to fig. 1 to 9, a surgical opening device according to an embodiment includes a bracket 100, a connection shaft 200, a guide head 300, and a prompt structure 400.

The bracket 100 serves as a structural bracket for the entire surgical opening device for installation of other related components of the surgical opening device. The bracket 100 includes a mounting cylinder 110.

The mounting cylinder 110 has a substantially hollow columnar shape.

The connection shaft 200 is slidably provided in the axial direction of the mounting tube 110 in the mounting tube 110. Specifically, the connection shaft 200 can also rotate relative to the mounting cylinder 110. The shaft wall of the connecting shaft 200 is provided with a groove 201.

The guide head 300 is connected to one end of the connection shaft 200, the guide head 300 can slide along the connection shaft 200 in the axial direction of the installation cylinder 110, a cutting edge is arranged on one side, close to the other, of at least one of the guide head 300 and the installation cylinder 110, the guide head 300 has a preset position relative to the installation cylinder 110, and the guide head 300 is positioned at the preset position when the surgical opening device completely cuts off tissues to be cut. In the illustrated embodiment, the predetermined position is the position of the guide head 300 relative to the mounting cylinder 110 in fig. 1 and 2, which is also the normal state of the surgical opening device, i.e., the state when not in use.

In one embodiment, the guide head 300 and the connecting shaft 200 are detachably connected, for example, connected by clamping, screwing, etc., and in this embodiment, a blade is provided on one side of the guide head 300 near the mounting cylinder 110, and a blade is also provided on one side of the mounting cylinder 110 near the guide head 300. Specifically, the guide head 300 can rotate with the connection shaft 200. When cutting tissue, the tissue is clamped between the blade of the mounting cylinder 110 and the blade of the guide head 300, and the guide head 300 is rotated by rotating the connecting shaft 200, so that the tissue is cut.

The prompting structure 400 is mounted on the bracket 100, the prompting structure 400 includes a prompting element 410 and an elastic element 420, the prompting element 410 can slide, the prompting element 410 can collide with the wall of the groove 201 to generate a prompting sound, and the elastic element 420 can provide an elastic force for the prompting element 410, so that the prompting element 410 can collide with the wall of the groove 201 when the guide head 300 slides to a preset position. That is, in the process that the connection shaft 200 slides in the axial direction of the mounting cylinder 110, when the guide head 300 slides to a preset position, the indicator 410 collides with the wall of the groove 201 by the elastic force of the elastic member 420 to make an indicator sound, and the indicator sound is "click" or "click" to indicate to the operator that the tissue cutting is complete.

The surgical opening device is used to open a hole in human or animal tissue (e.g., heart tissue) to facilitate subsequent cannula, attachment of auxiliary devices (e.g., ventricular assist pumps), and the like. In the process of cutting by using the surgical opening device, after the surgical opening device cuts the tissue, the prompting piece 410 collides with the groove wall of the groove 201 under the acting force of the elastic piece 420 to give a prompting sound to prompt the operator that the tissue cutting is completed, so that the operator is prevented from taking out the surgical opening device without cutting the tissue.

Based on the structural design of the surgical opening device of the present application, in the use process, firstly, a cross incision is cut on the tissue by using a cutting tool commonly used in the prior art, and secondly, a worker holds the surgical opening device by holding the mounting cylinder 110, the worker applies a force to the connecting shaft 200, slides the connecting shaft 200 along the axial direction of the mounting cylinder 110, and moves the mounting cylinder 110 and the guide head 300 away from each other, the guide head 300 passes through the cross incision, then the guide head 300 and the mounting cylinder 110 are moved close to each other, the connecting shaft 200 is rotated to cut the tissue, the guide head 300 returns to a preset position after the tissue is completely cut, at this time, the prompting piece 410 collides with the groove wall of the groove 201 under the elastic force of the elastic piece 420 to give a prompting sound, and the operator determines that the tissue has been cut after hearing the prompting sound.
