Perineum visual field exposing device

Abstract

The invention relates to a perineum visual field exposing device which comprises a fixing support (2), a dilator (5) and a lighting assembly, the fixing support (2) is used for detachably installing the dilator (5), the installation position of the dilator (5) on the fixing support (2) is adjustable, and the lighting assembly is installed on the fixing support (2). Compared with the prior art, the dilator (5) is fixed through the fixing support (2), the installation position of the dilator (5) is adjustable, an operator can operate independently, an assistant does not need to assist a drag hook, the operation space is saved, meanwhile, the position of the dilator (5) can be adjusted according to the operation requirement, in addition, the device is provided with illumination, repeated adjustment of exogenous illumination is avoided, operation is convenient, and the operation efficiency is improved. The sterile operation principle is met.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a perineal visual field revealing device. Background technique [0002] Abdominal perineal combined with radical rectal cancer surgery (Miles surgery) is suitable for patients with low rectal cancer who cannot preserve the anus for the purpose of radical tumor resection. Because the operation involves many parts, including the sigmoid colon, the whole rectum and its mesentery, the anal canal and the skin around the anal canal, the subcutaneous tissue, the entire anal sphincter, and the dissection of the lymph nodes in the inferior mesenteric artery, two operators are required to be located in the abdomen and the anal canal, respectively. The perineum cooperates with the above-mentioned tissue viscera resection. [0003] The perineal operation of the Miles procedure involves an incision of about 5 cm of the skin around the anal canal. At this time, the anal canal can be ...

Problems solved by technology

However, the operating space in the perineum is limited, and the assistant often stands on the outside of the patient's thigh to cooperate with the surgeon to expose the field of view. The long-term bending posture and the limitation of the line of sight may easily lead to insufficient exposure of the operative field, affecting the time and effect of the operation

[0004] The existing perineal expanders have the following disadvantages: (1) At least one assistant is required to cooperate with the operation, which is still limited by space and sight; (2) The operation is cumbersome, requiring the operator and the assistant to repeatedly adjust the stretching position , affect the operation process; (3) Some expanders are not fixed firmly, which increases the risk of operation; (4) There is no self-contained lighting device, and it needs to rely on external lighting, and the lighting angle has to be adjusted frequently due to the small space of the perineum
