Embodiment 1

[0042] like figure 1 As shown, an atrial stretch auxiliary device 2 in this embodiment is a connecting support structure, which is arranged on the inner part of the pericardium to be stretched by the fixed arm or the movable arm of the sternal retractor, including the sternal retractor fixing structure. 21 and the hook wire fixing structure 22, the two are separated and connected by welding. The sternal retractor fixing structure 1 has a fixing structure 201, and the fixing structure 201 is used to be fixed on the fixed arm or the moving arm of the sternal retractor. The hook wire fixing structure 22 has a hook wire fixing structure 206 for fixing the tissue pulling hook wire. When the sternal retractor fixing structure 21 is fixed to the fixed arm or the moving arm of the sternal retractor, the position of the hook wire fixing structure 206 is substantially flush with the inner part of the fixed arm or the moving arm Location.

Embodiment 2

[0048] like figure 2 As shown, an atrial stretch auxiliary device 2 in this embodiment is a connecting support structure, which is arranged on the inner part of the pericardial cavity being stretched by the fixed arm or the movable arm of the sternal retractor, and includes a sternal retractor. The fixing structure 21 and the wire hook fixing structure 22 are integrated. The fixing structure of the sternal retractor has a fixing structure 201, and the fixing structure 201 is used to be fixed on the fixed arm or the moving arm of the sternal retractor. The hook wire fixing structure 22 has a hook wire fixing structure 206 for fixing the tissue pulling hook wire. When the sternal retractor fixing structure 21 is fixed to the fixed arm or the moving arm of the sternal retractor, the position of the hook wire fixing structure 206 is substantially flush with the inner part of the fixed arm or the moving arm Location.

Embodiment 3

[0054] like image 3 As shown, an atrial stretch auxiliary device 2 in this embodiment is a connecting support structure, which is arranged on the inner part of the pericardial cavity being stretched by the fixed arm or the movable arm of the sternal retractor, and includes a sternal retractor. The fixing structure 21 and the wire hook fixing structure 22 are integrated. The fixing structure of the sternal retractor has a fixing structure 201, and the fixing structure 201 is used to be fixed on the fixed arm or the moving arm of the sternal retractor. The hook wire fixing structure 22 has a hook wire fixing structure 206 for fixing the tissue pulling hook wire.

[0055] like Figure 4 As shown, the elongated fixed arm 41 and the movable arm 42 of the sternum retractor are respectively provided with side U-shaped baffles 43 for spreading the sternum on the inner side of the exposed pericardium. The side U-shaped baffles 43 The sides of the fixed arm 41 and the moving arm 42 f...

Abstract

The invention relates to an atrium traction auxiliary device and an atrium drag hook. The atrium traction auxiliary device is of a connecting and supporting structure and comprises a sternum retractor fixing structural part and a hook line fixing structural part. The sternum retractor fixing structural member is provided with a fixing structure fixed on a fixed arm or a movable arm of the retractor, and the thread hooking fixing structural member is provided with a thread hooking fixing structure used for fixing a tissue traction suture. When the sternum retractor fixing structural part is fixed to the retractor, the position of the thread hooking fixing structure is basically flush with or lower than the position of the inner side of the fixed arm or the movable arm. The atrium drag hook comprises an atrium traction auxiliary device and further comprises a hook line structural part composed of a plurality of hook lines used for traction of tissue. According to the device, a drag hook is omitted, automatic traction is achieved on the premise that the surgical field is not shielded and surgical operation is not hindered, and the height and traction tension of the thread hooking fixing structure can be flexibly adjusted according to the position of a pulled tissue and the requirement for the surgical field, so that the optimal surgical field is obtained.

Description

technical field [0001] The invention relates to an atrial pulling auxiliary device and an atrial retracting hook, belonging to the technical field of cardiac surgical instruments. Background technique [0002] Cardiac surgery mainly includes coronary artery bypass grafting, heart valve surgery, congenital heart disease correction surgery, cardiac tumor resection, major vascular surgery and cardiomyopathy surgery. Cardiac surgery has the characteristics of long operation time, complexity, high difficulty and high risk. It is called the last fortress in the field of surgery by the medical community. A good surgical field of view is the basis for ensuring the smooth implementation of surgery and obtaining good results. Due to the surgical instruments, a good field of vision cannot be obtained during the operation, and the operation will be difficult, especially for cardiac surgery, which will be even more difficult. Sternal retractor is usually used to separate the sternum to...
