Embodiment 1

[0030] Such as figure 1 Shown is a schematic structural view of a three-dimensional suture fixer of the present invention, including: a fixer body 1, and the fixer body 1 includes: a three-dimensionally formed steel core 2, and a helical spring ring surrounding the steel core 2 3. The fixer body 1 is bent to form a multi-segment continuous bending segment for fitting with the outer thorax wall of the human body.

[0031] Specifically, as figure 2 As shown, the fixator body 1 is formed in a 3D three-dimensional shape, and is bent to form a plurality of continuous bending sections that are used to fit the outer wall of the lateral thorax of the human body.

[0032] Preferably, the outer thoracic wall is the right outer thoracic wall. Such as Figure 7 and Figure 8 As shown, during the operation, the patient is placed in the supine position with the right shoulder propped up. Place the fixator body 1 on the right thorax. A part of the fixator body 1 is placed on the right...

Embodiment 2

[0036] Such as Figure 1 to Figure 6 As shown, a three-dimensional suture fixer according to an embodiment of the present invention includes: a fixer body 1, a fixing ring 4 arranged on the fixer body 1, and a blunt ring 4 arranged at the end of the fixer body 1 fixed head 5, the fixer body 1 includes: a three-dimensionally formed steel core 2, and a helical spring coil 3 surrounding the steel core 2, the steel core 2 is a stainless steel core, and the steel core 2 The bending angle is adjustable, and the bending angle can be adjusted by fine-tuning the steel core before connection so that the three-dimensional suture fixer fits closely with the side chest;

[0037] The fixer body 1 is bent to form a multi-segment continuous bending segment that is used to fit the outer thoracic wall of the human body;

[0038] The bending section includes a first bending section 11 , a second bending section 12 , a third bending section 13 , and a fourth bending section 14 connected in seque...

Abstract

The invention discloses a three-dimensional suture fixer, comprising: a fixer body (1), and the fixer body (1) includes: a three-dimensionally formed steel core (2), and a steel core (2) surrounding the steel core (2). A spiral spring coil (3), the fixer body (1) is bent to form a multi-segment continuous bending segment and is used to fit the outer thorax wall of the human body. In the present invention, the fixer body is bent in multiple sections to form a multi-section continuous bending section that is used to fit the outer wall of the lateral thorax of the human body. The three-dimensional (3D) three-dimensionally formed open annular suture fixing device of the present invention can perfectly fit the outer wall of the patient's side thorax, and can closely fit the shape of the side thorax without affecting the entry and exit of other thoracoscopic surgical instruments. , The adjustment of the pericardial and atrial traction line.

Description

technical field [0001] The invention relates to the related technical field of medical equipment, in particular to a three-dimensional suture fixer. Background technique [0002] Heart valve surgery often requires more pre-placed sutures, such as valve sutures, pericardial suspension wires, and atrial traction wires. At present, the suture fixation device designed for median sternotomy has been maturely applied in the market, which can organize all the preset sutures, avoid the use of a large number of hemostats, and take into account the cleanliness, practicality and efficiency. [0003] However, with the rapid development of minimally invasive cardiac surgery, especially thoracoscopic cardiac surgery, the proportion of open heart surgery on the right lateral thoracic wall is increasing year by year. The main shape of the original suture fixing device is a flat rigid ring shape, while the contour of the side chest wall is curved, so the suture fixing device cannot be compl...
