Drainage device for single-side double-channel endoscopic surgery

Abstract

The invention provides a drainage device for a single-side double-channel endoscopic surgery. The drainage device comprises an isolating membrane, release paper, water absorption sponge and a water absorption pipe. Wherein the release paper is adhered to the isolating membrane and is torn off during use, so that the isolating membrane can be adhered to the skin surface of a human body; an annular structure formed by the water absorption sponge is fixed above the isolating membrane, and the middle part of the annular structure is a surgical operation area; the water absorption pipe is installed in the water absorption sponge and used for absorbing water generated in the operation and discharging the water out through a negative pressure suction pipe. According to the drainage device, the isolating membrane is pasted to the back of a patient after the release paper is torn off before an operation, a'water retaining dam 'can be directly formed, operation is convenient and fast, and compared with a traditional method for temporarily preparing the'water retaining dam' before the operation, early-stage preparation of medical staff is reduced; and the special shape of the back can be adapted, the water absorption performance is good, frequent movement of the suction pipe for sucking flushing fluid in the operation process is avoided, and then the workload is reduced.

Description

Technical field [0001] The present invention relates to a medical instrument field of assistive technology, particularly, to a single-sided dual-channel endoscopic surgical drain. Background technique [0002] Composed of spinal vertebrae, the vertebrae are connected between each other through the disc and ligaments, to maintain the body stably. Behind each arch the spine, lamina, spinous and transverse processes of the vertebrae composition, close to the surface, easily accessible, there is a common disease of the spine class lumbar disc herniation, spinal stenosis, spondylolisthesis and so on. [0003] Single-sided dual-channel endoscopic surgery, minimally invasive surgery is a new, can be accurate, minimally invasive manner effective to treat various diseases of the spine, as compared to traditional open surgery, with less trauma, less bleeding advantages, can reduce surgical risk patients, it is conducive to early rehabilitation of patients after surgery. One-side dual-chann...

Problems solved by technology

[0006] Therefore, the technical problem to be solved by the present invention is to overcome that there is no drainage device in the prior art that is suitable for draining the liquid drained from the surgical incision on the back of the human body to keep the surgical area dry, so that the doctor needs to set it up before the operation, resulting in a The time is extended and the suction tube needs to be moved at any time during the operation, which leads to the technical defect of increasing the workload, so as to provide a drainage device that can save operation time and does not need to move the suction tube at any time, which can reduce the workload of the operation
