Embodiment 1

[0030] Such as Figure 1-3 As shown, the balloon-type support device for laparoscopic surgery includes a hollow rod-shaped support rod 1, a bottom cover 11 is provided at the bottom of the support rod 1, a top cover 12 is provided at the top, and a slider is arranged inside the support rod 1 2. An accommodating chamber 13 is formed between the slider 2 and the bottom cover 11, the accommodating chamber 13 is provided with an airbag 3, the slider 2 is connected to the top of the airbag 3, and the side wall of the accommodating chamber 13 is provided with At least two openings 14, slide the slider 2 towards the bottom of the support rod 1, the airbag 3 protrudes from the opening 14 to the outside of the support rod 1, and also includes a support frame 9 buckled on the patient's abdomen, the support Frame 9 is made up of several connecting rods 91 detachable, and described support frame 9 is arc-shaped, and support leg 92 is arranged at the bottom of described support frame 9, an...

Embodiment 2

[0037] Such as Figure 1-3 As shown, the structure of the balloon-type supporting device for laparoscopic surgery in this embodiment is the same as that of Embodiment 1, the difference is that a spring 6 is sleeved on the handle 4, the bottom end of the spring 6 is connected with the slider 2, and the top end is Connected with the top cover 12, the top cover 12 is provided with a limiting ring groove 121, the handle 4 is provided with a limiting block 41, and the limiting chute 121 is provided with a Notch 122.

[0038] In the balloon-type support device for laparoscopic surgery in this embodiment, a spring 6 is provided between the top cover 12 and the slider 2, so that the spring 6 applies a force to the slider 2 to move toward the top cover 12, so that the slider can be restored to its original position. The unused initial position contacts the expansion part of the airbag 3 outside the support rod 1, which facilitates recovery of the support rod 1 and safely releases the ...

Embodiment 3

[0041] Such as Figure 1-3 As shown, the structure of the balloon-type support device for laparoscopic surgery in this embodiment is the same as that of Embodiment 1, the difference is that it also includes a sealing plate 7 for closing the opening 14, and the sealing plate 7 and the support rod 1 A rotating shaft 71 is arranged between them, and when the opening 14 is closed, the outer surface of the sealing plate 7 is coplanar with the outer surface of the support rod 1 .

[0042] The balloon-type support device for laparoscopic surgery of this embodiment, by setting the sealing plate 7 to close the opening 14 on the support rod 1, the air bag 3 is preferably limited in the support rod 1, and when the support rod 1 is placed in the abdominal cavity, the support The outer wall of the rod 1 will not cause damage to the poking hole, further avoiding additional pain to the patient. At the same time, when the air bag 3 extends out of the support rod 1, the sealing plate 7 is atta...

Abstract

The invention relates to the field of medical instruments, in particular to a balloon-type support device for laparoscopic surgery. The support device comprises a hollow rod-shaped support rod, a bottom cover is arranged at the bottom of the support rod, and a top cover is arranged at the top of the support rod. The support rod is provided with a slider, a receiving chamber is formed between the slider and the bottom cover, the receiving chamber is provided with a balloon, and the slider is connected at the top of the balloon. The side wall of the receiving chamber is provided with at least two openings, and the slider is slid toward the bottom of the support rod. The balloon protrudes from the opening to the outside of the support rod. The number of puncture holes is reduced, the connection between the support rod and the abdominal wall is stabilized, the structure is simple, the operation is convenient, and the work difficulty of the medical staff is reduced. Because the contact areabetween the balloon and the inner wall of the abdominal cavity is wider and the contact surface is smoother, on the one hand, the support device has better supporting effect, on the other hand, the pressure injury to the abdominal wall is avoided correspondingly, and the unnecessary trauma caused by surgery of the patient is reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a balloon type support device for laparoscopic surgery. Background technique [0002] Laparoscopic surgery mainly includes pneumoperitoneum surgery and gas-free laparoscopic surgery, both of which need to use a pneumoperitoneum needle to puncture the abdominal wall in advance to form a laparoscopic poke hole, and then introduce carbon dioxide or place in the channel connecting the outside world and the abdominal cavity formed by the puncture. Insert the suspension device, separate the abdominal wall and abdominal viscera, and establish a surgical space in the abdominal cavity. Since the carbon dioxide introduced by gas laparoscopic surgery is easily absorbed through the peritoneum, it will cause more complications for elderly patients. Therefore, for elderly patients, generally use Gas-free laparoscopic surgery. [0003] However, at present, in gas-free laparoscopic surgery,...
