[0002] With the increasingly serious aging of the population in China, the number of patients with various degenerative diseases has increased year by year. Lumbar disc herniation and spinal stenosis are common degenerative diseases in the elderly, which seriously affect the daily life of patients and even have the risk of disability. Some patients cannot relieve their conditions through conservative treatment and need to choose surgical treatment. In recent years, with the rapid development of minimally invasive spinal techniques, spinal endoscopy has become the preferred method for surgical treatment of lumbar disc herniation, spinal stenosis, etc.

[0003] A large amount of isotonic irrigation fluid is required for water flushing during spinal endoscopy. To prevent the irrigation fluid from wetting the surrounding area during flushing, during the current surgery, a cloth is first used to surround the surgical hole, and then a sterile waterproof film is pasted at the cloth opening to form a C-shaped dam to centrally block the isotonic irrigation fluid from overflowing and flowing randomly. This operation method is simple and crude, the placement shape of the surrounding cloth is unstable, and the effect of collecting the isotonic irrigation fluid is not good.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 5 , the present invention provides a technical solution: a disposable special drape for spinal endoscopy surgery, including a surgical drape 1 and a surgical hole 2 opened on the surgical drape 1.

[0023] It should be noted that the surgical drape 1 is composed of three layers, which are, from the outside to the inside, a non-woven fabric layer, an absorbent cotton core layer, and a non-woven fabric layer, and the composition structure is the prior art.

[0024] A surgical sterile membrane 3 is covered and placed on the surgical hole 2. The surgical sterile membrane 3 is set as a sterile PU membrane, and the membrane body is transparent, which is used to cover the skin exposed by the hole and can block the contamination of the surgical site and the instruments in use by the bacteria and metabolites of the skin.

[0025] Covering the surgical skin with the surgical sterile membrane 3 on the surgical drape 1 at the surgical hole 2 is a routine operation in surgical procedures, and the specific content will not be elaborated here.

[0026] A C-shaped flushing and diversion seat 5 is placed on the surgical sterile membrane 3, which inflates and bulges to surround the surgical hole 2. The cross-section of the seat body is peak-shaped, and a groove cavity 7 for receiving isotonic flushing liquid is formed inside the C-shaped flushing and diversion seat 5. A notch 8 is opened in the groove cavity 7 in the direction of the patient's back side for the collection and drainage of isotonic flushing liquid.

[0027] It should be noted that during use, the patient adopts the prone position. Generally speaking, the patient lies on his stomach with the back facing up, so the notch faces the side of the back.

[0028] In this embodiment, the C-shaped flushing and diversion seat 5 is set as an airbag seat, and an air valve port 6 is arranged on the outside. The bottom surface of the seat body is horizontal and the upper part is arc-shaped and convex, and a large semi-circular groove cavity 7 is formed inside. The surgical sterile membrane 3 is provided with arc-shaped symmetric adhesive tapes 4 on the upper surface to cooperate with the C-shaped flushing and diversion seat 5, and the bottom surface of the C-shaped flushing and diversion seat 5 is adhesively attached to the adhesive tape 4 for fixation.

[0029] During use, a rinsing liquid storage bag 9 is covered on the slot cavity 7. The rinsing liquid storage bag 9 is made of sterile PU film. The middle sheet body is fitted and contacted with the slot cavity 7 to form a bag groove for containing isotonic rinsing liquid.

[0030] In this embodiment, a shaping ring 10 is connected to the edge of the rinsing liquid storage bag 9. The shaping ring 10 is a hard plastic ring, and the C-shaped rinsing diversion seat 5 is C-shaped. During use, the shaping ring 10 is arranged along the outer wall of the C-shaped rinsing diversion seat 5, so that the edge of the shaped rinsing liquid storage bag 9 does not scatter and deform, and the bag mouth remains in an open state, allowing the inner side of the isotonic rinsing liquid bag contaminated on the bag surface to flow.

[0031] Then, a drainage bag 11 is connected at the notch 8. The drainage bag 11 is a sterile PU film bag, in a funnel shape. The funnel tail pipe is a long tubular plastic pipe, and a switch device is provided at the tail.

[0032] That is, the C-shaped rinsing diversion seat 5, the rinsing liquid storage bag 9 and the drainage bag 11 cooperate. A long plastic bag is connected in the non-notch direction, which is convenient for collecting the isotonic rinsing liquid overflowing from the puncture port or the instrument interface during the operation. With the funnel-shaped drainage bag 11, it is convenient for the isotonic rinsing liquid overflowing during the operation to be introduced into the drainage bag 11 from the notch 8, and the isotonic rinsing liquid in the drainage bag 11 is discharged through the tail plastic pipe. Among them, the switch device can be a stop valve to open and close the flow of the pipe body, facilitating the collection of isotonic rinsing liquid.

[0033] It should be noted that currently, a self-made combined device is used in the operation. The tail of the drainage bag 11 is also a film, and each time a pair of pliers is needed to clamp the tail and then put it into the recycling container. In this application, the tail is set as a plastic pipe. When in use, the valve is opened, and there is no need to use pliers to clamp it, which is more convenient to use.

[0034] Furthermore, to ensure the stable inflation and forming of the C-shaped rinsing diversion seat 5:

[0035] At the upper and lower ends inside the C-shaped rinsing diversion seat 5, a limiting band 12 and an elastic band 13 are respectively fixedly connected. The limiting band 12 is a hard plastic band, the elastic band 13 is a rubber band, and the limiting band 12 and the elastic band 13 are distributed at intervals.

[0036] That is, in the preparatory work before use, through the inflation device docking the air valve port 6, the C-shaped rinsing diversion seat 5 is inflated. The internal expansion size is restricted by the limiting band 12 to avoid excessive inflation. At this time, the elastic band 13 is in a stretched state. When the C-shaped rinsing diversion seat 5 needs to be deflated after use, the stretched elastic band 13 assists in exhausting air outward, improving the use speed and reducing the time consumed in the operation.

[0037] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
