Embodiment 1

[0061] Please refer to the attached figure 1 , attached figure 2 , with figure 1 It is a structural schematic diagram of a special tube-holding instrument for arterial and venous intubation in the anterolateral small incision heart surgery of this embodiment, with the attached figure 2 It is a structural schematic diagram of the left clamp of a special tube-holding instrument for arterial and venous cannula in the anterolateral small incision cardiac surgery of this embodiment. The special-purpose tube-holding instrument for arterial and venous cannula in the anterolateral small incision cardiac surgery comprises a left clamp (1), a right clamp (2), and a coupling pin (3); the left clamp (1) consists of a left handle ( 11), the left front transmission rod (12), the left joint (13), the left rear transmission rod (14) and the left pincer head (15); the left handle (11) is semicircular Ring-shaped, the head of the left handle (11) is fixedly connected with a left front tran...

Embodiment 2

[0066] Please refer to the attached Figure 7 , attached Figure 8 , with Figure 7 It is a structural schematic diagram of a special tube-holding instrument for arterial and venous intubation in the anterolateral small incision heart surgery of this embodiment, with the attached Figure 8 It is a partial schematic diagram of a special tube-holding instrument for arterial and venous cannula in the anterolateral small incision heart surgery of this embodiment.

[0067] This embodiment is basically the same as Embodiment 1, except that a lock (4) is installed on the tube-holding instrument.

[0068] The special tube-holding instrument for arterial and venous intubation in anterolateral small incision heart surgery includes left forceps (1), right forceps (2), coupling pin (3), and locking buckle (4); the left forceps (1) ) is made up of left handle (11), left front side transmission rod (12), left side junction (13), left rear side transmission rod (14) and left side pincer h...

Embodiment 3

[0073] Please refer to the attached figure 1 , with figure 1 It is a structural schematic diagram of a special tube-holding instrument for arterial and venous cannulation in anterolateral small incision heart surgery in this embodiment.

[0074] The use process and method of the special tube-holding instrument for arterial and venous cannula in the anterolateral small incision cardiac surgery:

[0075] First, when performing anterolateral small incision cardiac surgery, the left hand handle (11) and the right hand handle (21) are held by hand, and the left side forceps head (15) and the right side forceps head (25) are passed. To grasp the arterial and venous cannulas, it can effectively prevent the slippage and the retraction of the stylet when the aortic cannula is clamped by ordinary vascular forceps or forceps. Using the tube-holding instrument to grasp the head end of the vena cava cannula can be turned more flexibly, so as to facilitate the delivery of the venous cannu...

Abstract

The invention relates to a special pipe holding apparatus for venous incubation of anterolateral small incision cardiac surgery, which comprises a left clamp, a right clamp and a combining pin; the left clamp is composed of a left side handle, a left front side conveying rod, a left side combining part, a left back side conveying rod and a left side clamp head; the right clamp is composed of a right side handle, a right front side conveying rod, a right side combining part, a right back side conveying rod and a right side clamp head; the combining pin is composed of a pin base and a pin head.The special pipe holding apparatus has the advantages that a flexible and stable operation tool is provided for venous incubation required by extracorporeal circulation of the anterolateral small incision cardiac surgery; the possibility of influence on cannula by pipe core returning and even cannula slippage caused by unstable apparatus clamping for untight bonding of the pipe core and the pipe wall can be reduced during the aorta cannula process of such minimally invasive surgery; the flexibility of cannula head steering is greatly improved, the difficult of delivering a venous cannula to vena cava is solved; besides, the safety of this operation is greatly improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a special tube-holding instrument for arterial and venous cannula in anterolateral small incision heart surgery. Background technique [0002] Open-heart surgery for the treatment of congenital heart malformations requires intubation of the ascending aorta and vena cava to establish connections between the patient's arterial and venous blood vessels and the pipeline of the extracorporeal circulation machine, and the heart can only be opened with the assistance of the extracorporeal circulation machine The incision is made to work inside the heart. The aorta and superior vena cava are located at the cranial end, while the inferior vena cava is located at the crural end. The median longitudinal incision of the sternum can well expose these large vessels that need to be intubated at the same time. The intubation operation is more convenient, safe and reliable. When card...
