Embodiment Construction

[0028] The technical solutions in the typical embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] like figure 1 As shown in the figure, a cardiac tissue retractor provided in this embodiment includes a non-invasive clip 1 at the proximal end for clamping the tissue at the incision of the heart, a fixed clip 2 at the distal end, and a traction rope 3 connecting the two. The clamping position of the fixed clip 2 and / or the atraumatic clip 1 changes the pulling force and pulling direction of the tissue at the cardiac incision;

[0030] The damage-free clip 1 includes an upper clip body 11 with an upper clip part 13 and a lower clip body 12 with a lower clip part 14. The upper clip part 13 and the lower clip part 14 are both arc-shaped plates and cooperate with each other , and they are all inclined to the side of the lower clip body 12, such as figu...

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a heart tissue retractor which comprises a non-injury clip at the near end and used for clamping tissue at a heart incision, a fixing clip at the far end and a traction rope for connecting the non-injury clip and the fixing clip. The traction force and the traction direction of the tissue at the heart incision are changed by adjusting the forceps holder position of the fixing clamp and / or the non-injury clamp; wherein the damage-free clamp comprises an upper clamp body with an upper clamping part and a lower clamp body with a lower clamping part, and the upper clamping part and the lower clamping part are arc-shaped plates, are matched with each other and are inclined towards one side of the lower clamp body; the traction force and the traction direction of the tissue at the heart incision can be changed by adjusting the clamping positions of the non-injury clamp and the fixing clamp, the position adjustment is convenient and rapid, and meanwhile, the damage to the tissue can be avoided.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a cardiac tissue retractor. Background technique [0002] In cardiac surgery, various incisions are required to expose the aortic valve, left ventricular outflow tract, or left atrial structures (such as left atrial appendage, mitral valve, etc.), or right atrial structures (such as atrial septum, tricuspid valve, etc. ), or pulmonary valve, right ventricular outflow tract and other structures. [0003] The traditional method is to pull the incision by sutured traction wire so that the operator can see the internal structure, so as to carry out the next operation. However, the method of suturing the traction wire needs to sew multiple sutures on the heart tissue, which is easy to cause damage to the heart tissue. In addition, with the progress of the operation, it is necessary to adjust the pulling direction and pulling strength of the traction wire at any time to better...
