Embodiment 1

[0037] Such as figure 1 , 2 The minimally invasive light source hook shown includes a base body 1 and an integrated hook 11 protruding laterally from the bottom of the base body 1. The end of the hook 11 is a warped sheet with an arc-shaped curved surface. 12. The middle part of the substrate 1 is provided with a suspension part 13; the back of the substrate 1 is provided with a traction device 2, the traction device 2 is a steel wire, the top of the traction device 2 passes through the hole on the surface of the substrate 1 to the front, and the top of the traction device 2 is connected with a The ring 21 is connected to the end of the traction device 2 with a path guiding device 22 arranged on the bottom surface of the drag hook 11 , and two opposite expansion pieces 23 are installed on both sides of the path guiding device 22 .

[0038] In this embodiment, the outer surface of the extension sheet 23 is an arc-shaped curved surface.

[0039] In this embodiment, there is al...

Embodiment 2

[0046] The technical solution described in embodiment two is similar to embodiment one, and its difference is:

[0047] Such as image 3 As shown, in this embodiment, the path guiding device 22 is a hinge 222 structure with a restoring device. The hinges 222 can be in a superimposed state as shown in the figure, or can be in a separate state arranged side by side.

Embodiment 3

[0049] The technical solution described in embodiment three is similar to embodiment one, and its difference is:

[0050] Such as image 3 As shown, in this embodiment, the path guiding device 22 is a gear set 223 with a restoring device.

[0051] The gear set 223 can be as shown in the figure with an adjustable stop wheel in the middle to adjust the opening of the expansion piece 23; or it can be two gears with relative rotation.

Abstract

Provided is a minimally-invasive light source hook. The light source hook includes a base body and a hook body transversely protruding out of the bottom of the base body, and the end part of the hookbody is a cocked sheet with an arc-shaped surface. The light source hook is characterized in that the top of the base body is provided with a handle protruding transversely, and a suspended part is arranged in the middle of the base body; a traction device is arranged on the back surface of the base body, the top end of the traction device penetrates from the base body to the front surface, a pulling ring is connected to the top end of the traction device, the tail end of the traction device is a path guiding device arranged on the bottom surface of the hook body, and an extensible sheet is installed on the path guiding device. The minimally-invasive light source hook has the advantages of being small in size, great in created operation environment, convenient to observe and operate, highin extension adaptability and capable of avoiding damage to the human body.

Description

technical field [0001] The invention relates to the field of medical instruments for thoracoabdominal minimally invasive surgery, in particular to a minimally invasive light source hook. Background technique [0002] With the development of electron microscopic technology and remote control technology, surgical operations are becoming more and more minimally invasive. How to ensure a good field of vision and provide enough operating space for surgical tools while protecting tissues from injury in minimally invasive surgery is a key issue in minimally invasive surgery. Problems that technology needs to solve. [0003] Especially in thoracoabdominal surgery, there are many organs in the abdominal cavity and thoracic cavity, and they are in contact with each other. The above problems need to be solved urgently. [0004] As the application number is 92207880.7 described a kind of multifunctional upper abdomen suspension automatic draw hook, it hangs draw hook in the future by s...
