Incision balloon dilator special for pleuroperitoneal cavity surgery

Abstract

The invention discloses an incision balloon dilator special for pleuroperitoneal cavity surgery. The incision balloon dilator further comprises a plurality of dilating rings, wherein the same balloon is arranged on the arc-shaped inner sides of the dilating rings; one side of each dilating ring is fixedly connected with a plurality of shaping wires; the shaping wires are arranged to limit the corresponding portions of the balloon to form a concave structure when the balloon expands; a plurality of liquid discharging holes are formed in the concave structure; liquid discharging branch pipes are fixedly connected to the liquid discharging holes; a liquid discharging annular pipe is arranged in the balloon; one end of each liquid discharging branch pipe is fixedly connected to the liquid discharging annular pipe; a liquid discharging main pipe is fixedly connected to the side wall of the liquid discharging annular pipe; and one end of the liquid discharging main pipe penetrates through the balloon. According to the scheme, tissue fluid generated at the contact position of an incision and the balloon dilator is discharged, other complications caused when the tissue fluid drips into the body of a patient are avoided, the balloon makes contact with the incision, and therefore the incision tissue is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an incision balloon dilator for thoracoabdominal surgery. Background technique [0002] In thoracoabdominal surgery, when the doctor makes an incision on the patient's surgical site, the incision will close automatically due to the contraction of human tissue, affecting the normal operation of the operation. In order to ensure the normal operation of the operation, it is necessary to use an incision dilator to retract the incision , to obtain a wider field of view, which is convenient for doctors to perform surgical treatment. [0003] For example, the publication number is that CN210095804U Chinese patent discloses a kind of incision dilator for general surgery, comprising a first expansion board, a second expansion board and a miniature air pump, air bags are installed at the left and right ends of the bottom of the first expansion board, so The second expansion plate ...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned equipment has the following disadvantages: the first expansion plate and the second expansion plate are in contact with the tissue at the incision, and the incision at the surgical site will continuously produce interstitial fluid, which will drip along the first expansion plate and the second expansion plate. In the patient's body, the interstitial fluid cannot be processed in time, leading to other complications in the patient
