Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a water retaining device for transforaminal endoscopic surgery. Background Art

[0002] Perforaminal endoscopic lumbar surgery is commonly used in clinical practice to treat lumbar disc herniation. Through a certain specific pipeline system combined with an endoscopic system, the pipeline system is passed through a certain anatomical structure into the site of disc herniation. Under endoscopic visualization, some specific instruments are used to remove the herniated disc, thereby achieving effective nerve release.

[0003] Before percutaneous endoscopic lumbar disc surgery, a disposable dressing pack needs to be pasted and covered around the surgical site; and during percutaneous endoscopic lumbar disc surgery, the surgical site needs to be flushed to improve the field of view during surgery, prevent the patient from having low body temperature, and prevent incision infection. A water collection bag is provided on one side of the U-shaped sheet of the disposable auxiliary material package to collect liquid during the flushing process. At the same time, in order to allow the liquid to flow down from one side of the water collection bag, the sheet is usually folded and bent into a U-shaped water barrier and laid around the surgical site, and the water barrier is covered with multiple layers of transparent dressings and then bonded to other dressings, thereby guiding the liquid to flow down from one side of the water collection bag. However, there is a problem of inconvenient operation, and the additional use of multiple layers of dressings leads to higher costs. Summary of the invention

[0004] The purpose of the present invention is to provide a water retaining device for transforaminal endoscopic surgery, which has the advantages of convenient operation and reduced use cost.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a water-blocking device for percutaneous endoscopic lumbar disc surgery, comprising a U-shaped sponge body used to surround the periphery of the patient's surgical site, and a waterproof cloth cover wrapped around the outside of the sponge body, a waterproof cloth strip is provided on the outer bottom edge of the waterproof cloth cover, a first viscose layer is provided on the lower surface of the waterproof cloth strip, and a first release tape covering the first viscose layer and capable of being torn off is provided on the first viscose layer.

[0006] The present invention is further configured as follows: a plurality of water absorption holes are provided at the bottom of the waterproof cloth cover near the bending part of the sponge body, a drainage pipe for connecting the drainage pipe is provided at the part of the waterproof cloth cover near the two ends of the sponge body, a flexible connecting belt is provided around the drainage pipe, and a plastic sealing cover is provided on the flexible connecting belt which has an interference fit on the drainage pipe to achieve sealing.

[0007] The present invention is further configured as follows: the waterproof cloth cover is made of waterproof non-woven fabric, and a display strip with built-in anhydrous copper sulfate is arranged on the inner side of the top of the waterproof cloth cover near both ends of the sponge body.

[0008] The present invention is further configured as follows: an electrostatic dressing tape for sticking is provided on the inner bottom edge of the waterproof cloth cover.

[0009] The present invention is further configured as follows: it also includes a water collecting bag, the two ends of the opening of the water collecting bag are detachably connected to the outer side of the waterproof cloth cover close to the two ends of the sponge body, the outer surface of one side edge of the opening of the water collecting bag is provided with a second viscose layer, and the second viscose layer is provided with a second release tape covering the second viscose layer and being torn away.

[0010] The present invention is further configured as follows: a shaping strip made of iron wire is arranged inside the edge of the other side of the opening of the water collecting bag to open the opening of the water collecting bag after deformation.

[0011] The present invention is further configured as follows: connecting ears are provided at both ends of the opening of the water collecting bag, and snap fasteners are provided between the connecting ears and the waterproof cloth cover.

[0012] In summary, the present invention has the following beneficial effects:

[0013] 1. During the transforaminal endoscopic surgery, the sponge body and the waterproof cloth cover are first placed around the surgical site of the patient; then the waterproof cloth strip is turned outward, the first release tape is torn off, and the waterproof cloth strip is pasted through the first adhesive layer; finally, the water-blocking effect is achieved, which has the advantages of convenient operation and low use cost;

[0014] 2. During the perforaminal endoscopic surgery, the flushing liquid slowly overflows from the surgical site of the patient. At this time, the liquid will also penetrate toward the bend of the spongy body. In order to reduce the leakage caused by the uneven adhesion of the first adhesive layer, multiple water absorption holes are set at the bottom of the bend of the spongy body. At this time, the liquid can be absorbed by the spongy body; at the same time, when the liquid of the spongy body is absorbed to a certain amount, the plastic sealing cover of the drainage tube is removed, and the drainage tube is connected to the drainage tube to achieve drainage;

[0015] 3. A display bar with anhydrous copper sulfate is set on the inner side of the top of the waterproof cloth cover near both ends of the sponge. The anhydrous copper sulfate turns blue when it comes into contact with water. When the display bar turns blue, it means that a large amount of liquid has been absorbed in the sponge, and the liquid can be drained through the drainage pipe at this time;

[0016] 4. An electrostatic dressing tape for pasting is arranged at the inner bottom edge of the waterproof cloth cover, so as to waterproof the inner and outer sides of the waterproof cloth cover, and cooperate with the water absorption holes on the waterproof cloth cover to achieve multiple protection effects;

[0017] 5. It also includes a water collection bag. The two ends of the opening of the water collection bag are detachably connected to the outer sides of the waterproof cloth cover near the two ends of the sponge body. After tearing off the second release tape, the outer surface of the edge of one side of the opening of the water collection bag is pasted, so that the liquid can flow into the water collection bag, without using the U-shaped sheet in the disposable dressing package;

[0018] 6. A shaping strip made of iron wire is arranged on the other side edge of the opening of the water collecting bag to open the opening of the water collecting bag after deformation, so as to facilitate opening the opening of the water collecting bag after the shaping strip is deformed, so that liquid can flow into the water collecting bag.
