[0003] In the prior art, the fixer fixed on the side of the bed is usually used as the basis for positioning the expansion system to realize the positioning function, but the expansion system in the prior art can only have a fixed expansion size, if necessary, it has a different If the size of the spreader is larger, the accessories of the spreader need to be replaced
Such an operation is very tedious and time-consuming

Abstract

The invention provides a minimally invasive mitral valve reactor comprising a rake-angle adjusting bar (1), a guide bar (2), a fastening portion (5) and a self-positioning expanding unit (6). The rake-angle adjusting bar (1) can be slidably inserted into and pass through the guide bar (2); a through hole is formed in the top of the fastening portion (5), the lower portion of the guide bar (2) is inserted into the through hole of the fastening portion (5) in a fastened manner, and when the rake-angle adjusting bar (1) slides in the guide bar (2), the guide bar (2) is fixed relatively to the fastening portion (5); the lateral side of the fastening portion (5) is pivotally connected with the self-positioning expanding unit (6), so that when the rake-angle adjusting bar (1) is adjusted to drive the fastening portion (5) to pivot, an angle between the guide bar (2) and the self-positioning expanding unit (6) can be adjusted according to the distance that the rake-angle adjusting bar (1) slides in the guide bar (2), and the self-positioning expanding unit (6) is enabled to keep in a position corresponding to the angle.

Description

technical field [0001] The present invention relates to the field of medical devices, and more particularly, to a minimally invasive mitral valve retractor for use in cardiac surgery. Background technique [0002] In cardiac surgery, multiple instruments need to cooperate to complete the operation on a certain operating area. When the operator operates one of the instruments, the other instruments should be stably fixed in a certain position to complete the corresponding auxiliary actions. In order to realize this positioning, a positioning and opening system is generally provided during the operation, and the positioning and opening system can keep a certain designated incision open so as to operate on the tissue inside the incision. [0003] In the prior art, the fixer fixed on the side of the bed is usually used as the basis for positioning the expansion system to realize the positioning function, but the expansion system in the prior art can only have a fixed expansion s...
