TECHNICAL FIELD
[0001] The present application relates to the technical field of surgical auxiliary devices, in particular to an antibacterial surgical film water collection negative pressure system. BACKGROUND
[0002] In the field of modern spine surgery, unilateral biportal endoscopy (UBE) as a minimally invasive technique has been widely used in the examination and treatment of spinal diseases. This technique uses two transverse incisions about 0.5-1.0 cm long on the patient's back as an observation channel and an operation channel. The endoscope is inserted through the observation channel, and a clear working space is formed in the body cavity by continuously perfusing sterile saline. At the same time, with the help of the high-definition magnified image provided by the endoscope, the surgeon can accurately operate the surgical instruments to effectively treat problems such as herniated disc and spinal stenosis. Its advantages of small trauma, fast recovery, clear vision, etc. make it an important choice for minimally invasive spine surgery. However, UBE surgery still faces some challenges in clinical application. The continuously perfused sterile saline will overflow through the operation channel, flow along the patient's body to the operating table, bed sheet and even the ground, not only destroying the sterile environment of the surgical area, but also increasing the risk of intraoperative hypothermia, postoperative wound infection, etc. Among them, the more serious complications are: intraoperative hypothermia can cause multiple damages to the patient's physiological functions, significantly increase the perioperative risk, such as causing cardiovascular events, severe bleeding, infection complications, delayed recovery, chills and delirium, etc. Therefore, the development of a surgical auxiliary device that can effectively solve the problem of overflow of sterile saline and prevent intraoperative hypothermia caused by it has become a key research direction in the field of spine surgery, especially for UBE surgery. Technical innovation is needed to provide patients with a safer and more efficient surgical experience during the perioperative period, reduce perioperative complications, and promote the further development of minimally invasive spine surgery technology. SUMMARY
[0003] The purpose of the present application is to provide an antibacterial surgical film water collection negative pressure system that can overcome the problem of overflow of continuously perfused sterile saline through the operation channel during endoscopic surgery in the field of spine surgery, which flows along the patient's body to the operating table, bed sheet and even the ground, resulting in destruction of the sterile environment of the surgical area, and the resulting risk of intraoperative hypothermia, postoperative wound infection, etc.
[0004] The present application discloses an antibacterial surgical film water collection negative pressure system, which comprises:
[0005] A water collection main body, the shape of the water collection main body is configured to enclose a water collection area outside the surgical incision on the surface of the patient's body, and the water collection main body is distributed with a microporous structure facing the human stoma;
[0006] A waterproof membrane is provided, which covers the water collection body and the water collection area. The waterproof membrane is provided with a surgical operation port corresponding to the human stoma. The waterproof membrane is also provided with liquid passage holes facing the microporous structure.
[0007] A negative pressure drainage tube, wherein the head end of the tube body is fitted and connected to the microporous structure; and the tail end of the tube body is connected to a negative pressure source.
[0008] This technical solution involves the following steps: During surgery, saline solution overflowing from the stoma collects in a collection area enclosed by the main collection body. This saline solution passes through the liquid pores and waterproof membrane to reach and infiltrate the microporous structure. Simultaneously, a negative pressure source is activated, creating negative pressure at the tip of the negative pressure drainage tube to draw the sterile saline solution out of the microporous structure. Thus,
[0009] This invention can avoid the problem of sterile saline continuously infused during spinal endoscopic surgery (especially UBE surgery) overflowing through the operating channel and flowing along the patient's body to the operating table, bed sheets, or even the floor, thus ensuring a sterile environment in the surgical area, reducing the risk of infection, and preventing intraoperative hypothermia.
[0010] Preferably, in the above-mentioned antibacterial surgical membrane water collection negative pressure system, the water collection body has a ring structure; the water collection body includes two sponge layers, which are respectively arc-shaped and symmetrically distributed on the inner ring surface of the water collection body; the remaining part of the water collection body is a water-proof layer.
[0011] This technical solution utilizes a sponge layer to provide a microporous structure for the absorption of saline solution. Simultaneously, a waterproof layer prevents saline solution from leaking out from the back of the sponge layer towards the stoma, ensuring the pumping effect of the negative pressure drainage tube. Furthermore, by dividing the sponge layer into two independent structures, the adsorption capacity of the negative pressure suction tube for saline solution within the sponge layer is optimized.
[0012] Preferably, in the above-mentioned antibacterial surgical membrane water collection negative pressure system, the water-proof layer has through holes that lead to the two sponge layers respectively, and the number of negative pressure drainage tubes is configured to be two. The tube heads of the two negative pressure drainage tubes are respectively attached to the two sponge layers through suction cups fixed in the through holes.
[0013] By adopting this technical solution, which utilizes a suction cup structure that penetrates the waterproof layer, leakage of saline solution is prevented during the extraction process, thus optimizing the placement of the negative pressure drainage tube.
[0014] Preferably, in the above-mentioned antibacterial surgical membrane water collection negative pressure system, each of the negative pressure drainage tubes includes two branch tubes, and the two branch tubes are respectively connected to the sponge layer by suction cups.
[0015] By adopting this technical solution, the saline solution absorbed in each sponge layer can be extracted from multiple directions, ensuring the uniformity of the extraction speed.
[0016] Preferably, in the above-mentioned antibacterial surgical membrane water collection negative pressure system, the number of liquid passage holes is even, and the even number of liquid passage holes are configured to be distributed evenly on the waterproof membrane facing the two sponge layers.
[0017] By adopting this technical solution, the saline solution is ensured to flow at a relatively uniform speed to the sponge layer on the side facing the stoma, thereby achieving uniform absorption of the saline solution by the sponge layer.
[0018] Preferably, in the above-mentioned antibacterial surgical membrane water collection negative pressure system, the negative pressure source includes a negative pressure aspirator, an air tube, and a waste liquid cylinder. The top of the waste liquid cylinder is provided with a sealing cap. The tail end of the negative pressure drainage tube passes through the sealing cap and extends into the waste liquid cylinder. One end of the air tube passes through the sealing cap and extends into the waste liquid cylinder, and the other end is connected to the negative pressure aspirator.
[0019] This technical solution involves using a negative pressure suction device to achieve negative pressure suction and discharging the suctioned saline solution into a waste container.
[0020] Preferably, the waterproof film is made of an antibacterial material.
[0021] Compared with existing technologies, this invention avoids the problem of sterile saline solution continuously infusing during spinal endoscopic surgery (especially UBE surgery) overflowing through the operating channel and flowing along the patient's body onto the operating table, bed sheets, and even the floor. This ensures a sterile environment in the surgical area, reduces the risk of infection, and prevents intraoperative hypothermia. Furthermore, this invention has the advantages of simple structure, ease of preparation, and ease of operation. Attached Figure Description

[0027] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.
[0028] Example 1, please refer to Figs. 1-3 :
[0029] An antibacterial surgical membrane-based negative pressure drainage system includes: a water collection body 100, a waterproof membrane 200, and a negative pressure drainage tube 300.
[0030] The water collection body 100 is configured to enclose a water collection area outside the surgical incision on the patient's body surface. The water collection body 100 has microporous structures distributed on it, facing the stoma. In this example: the water collection body 100 has a ring-shaped structure; the water collection body 100 includes two sponge layers 110, each of which is arc-shaped and symmetrically distributed on the inner annular surface of the water collection body 100; the remaining portion of the water collection body 100 is a water-resistant layer 120. The waterproof layer 120 has four through holes, which are connected in pairs to two sponge layers 110. Suction cups 340 are installed on each of the four through holes. Two negative pressure drainage pipes 300 are configured, each including a main pipe 310 and two branch pipes 320. The ends of the two branch pipes 320 are respectively connected to the same sponge layer 110 via a suction cup 340. The bodies of the two branch pipes 320 are connected to the main pipe 310 of the negative pressure drainage pipe 300, which in turn is connected to a negative pressure source.
[0031] The waterproof membrane 200 is made of antibacterial material. The waterproof membrane 200 is sized to at least cover the water collection body 100 and the water collection area. The waterproof membrane 200 has a rectangular surgical opening 220 located corresponding to the stoma. The waterproof membrane 200 also has liquid passage holes 210 facing the microporous structure. In this example, there are 6 or 8 liquid passage holes, which are evenly distributed on the waterproof membrane 200 facing the two sponge layers 110.
[0032] The negative pressure source includes a negative pressure suction device 400, an air tube 330, and a waste liquid cylinder 500. The top of the waste liquid cylinder 500 is equipped with a sealing cap. The tail end of the negative pressure drainage tube 300 passes through the sealing cap and extends into the waste liquid cylinder 500. One end of the air tube 330 passes through the sealing cap and extends into the waste liquid cylinder 500, while the other end is connected to the negative pressure suction device 400. A backflow prevention valve may also be provided at the connection between the air tube 330 and the negative pressure suction device 400.
[0033] In practice, its working process is as follows:
[0034] During the procedure, the water collection body 100 is fixed to the patient's skin with an adhesive dressing, and a waterproof film 200 is placed over it. The waterproof film 200, except for covering the water collection body 100, adheres to the patient's skin, allowing the cephalostomy to protrude from the surgical opening 220. During the procedure, saline solution overflowing from the stoma reaches and permeates the microporous structure through the fluid pores 210. Simultaneously, the negative pressure suction device 400 is activated, creating negative pressure at the ends of each branch of the negative pressure drainage tube 300. This draws the saline solution adsorbed in the sponge layer 110 and directs it into the waste container. This overcomes the problem of saline solution used for irrigating the incision flowing down the patient's body onto the operating table, sheets, or even the floor during UBE surgery, contaminating the sterile environment of the surgical area, increasing the risk of infection, and causing intraoperative hypothermia.
[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
