Problems solved by technology

During the insertion of the brain pressure plate, the brain pressure plate and the damaged tissue around the wound rub against each other, causing secondary damage to the wound and its surrounding tissues, which will easily lead to increased bleeding and wound expansion, which will cause unnecessary harm to the patient. Trauma and pain; and there are relatively many steps, which take up a certain amount of time, and require surgical operations such as hemostasis for patients

Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings.

[0034] Such as Figures 1 to 6 The surgical wound retraction device shown includes a flexible retraction assembly 40 and a deformable sleeve 10 .

[0035] The flexible retractor assembly 40 includes an expansion balloon 41 , a stent 42 and an inflation device 43 . Wherein, the expansion balloon is made of elastic material, can be contracted to enter the diseased part and can be expanded to form a retracting channel for the said diseased part. The bracket 42 is used to keep the expansion balloon 41 in a cylindrical shape, and the inflation device 43 is used to fill the expansion balloon 41 with gas or liquid to make it inflated. The expansion balloon 41 is coated on the outer wall of the stent 42 , and the inflation device 43 is connected with the expansion balloon 41 . The deformable sleeve 10 deforms and expands together with the expansion balloon 41 and can be sol...

Abstract

The invention discloses a surgical wound retractor. The surgical wound retractor includes a flexible retracting assembly and a deformable pipe sleeve. The flexible retracting assembly includes an expandable balloon, a support and an inflating device. The deformable pipe sleeve can deform and expand with the expandable balloon, and can fix and keep the shape so as to open a retracting channel; andthe deformable pipe sleeve and the expandable balloon are separated from each other. The surgical wound retractor can retract a wound or channel to be retracted from inside in an operation, can reducesecondary damage to the wound and surrounding tissues thereof due to the retractor, and can relieve pains of a patient in the operation.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a device for retracting surgical wounds. Background technique [0002] During surgical procedures, medical personnel need to use their retractor devices to locate muscle tissue, blood vessels, nerves and other tissues so that the operation site can be accessed. Surgical retractors are of particular importance in many surgical procedures, especially those involving cerebrovascular and neurological procedures. The traditional brain tissue retraction and the establishment of the surgical channel mainly rely on the brain pressure plate (stainless steel sheet) to use the anatomical structure of the brain to retract the brain tissue. Cerebral blood vessels and nerves are easily damaged during the process, and brain stretch injuries can be seen everywhere. After retraction, due to the creep characteristics of brain tissue, the expanded channel is easy to shrink and become s...
