Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to a waterproof backflow device for percutaneous endoscopic discectomy. Background Technology

[0002] Lumbar disc herniation is a common clinical condition caused by the degeneration and rupture of the nucleus pulposus due to various reasons, protruding posteriorly into the lamina and compressing or irritating adjacent tissues, causing a series of clinical symptoms such as lower back pain and nerve root pain on movement. In severe cases, surgery is required to remove excess disc tissue to relieve nerve root compression and damage, and restore spinal neuromuscular function. Traditional open surgery is highly invasive and has a high rate of postoperative complications. With continuous technological advancements, minimally invasive spinal surgery, represented by percutaneous endoscopic discectomy, has been widely used in the treatment of lumbar disc herniation.

[0003] Percutaneous endoscopic discectomy (PED) involves making a small incision to create a working channel in the intervertebral foramen of the lumbar spine to reach the herniated disc. Using a spinal endoscope, the tissues and anatomical structures inside the spine are transmitted to an external monitor. The doctor then operates by observing the monitor and removes the herniated disc through the created channel, thus achieving the treatment goal.

[0004] Percutaneous endoscopic discectomy (PED) requires a water flow environment. The device consists of a main body, a handle, and a lens. One end of the main body is the working port, and a water inlet is located on the outer circumference of the main body. The handle is obliquely fixed to the outer wall of the main body, and the lens is threaded onto the end of the main body opposite to it. During lateral approach PED with the patient in a prone position, due to the patient's position and ease of operation for the staff, the working port on the main body is usually higher than the handle. This causes water from the working port to easily flow back onto the handle and then down the handle onto the lens, resulting in blurred vision. The surgery must be stopped and the lens cleaned before continuing, affecting the surgical progress and posing a safety hazard. Utility Model Content

[0005] To reduce surgical safety risks, this application provides a waterproof backflow device for percutaneous endoscopic discectomy.

[0006] The technical solution of the waterproof backflow device for percutaneous endoscopic discectomy provided in this application is as follows:

[0007] A waterproof backflow device for a percutaneous endoscopic discectomy includes an upper water-blocking component and a lower water-blocking component. Both the upper and lower water-blocking components are semi-circular and located on the outer circumferential wall of the handle of the target percutaneous endoscopic discectomy unit. The projections of the upper and lower water-blocking components onto the diameter plane of the handle of the target percutaneous endoscopic discectomy unit are circular. A water-guiding groove is provided at the top of both the upper and lower water-blocking components.

[0008] Optionally, the wall of the water channel near the handle of the target percutaneous endoscopic disc is inclined.

[0009] Optionally, both the upper and lower water-blocking components have multiple suction cup grooves at one end near the handle of the target percutaneous endoscopic disc.

[0010] Optionally, the upper and lower water-blocking components are provided with multiple receiving grooves at one end of the handle near the target percutaneous endoscopic disc, and the multiple receiving grooves and multiple suction cup grooves are distributed at intervals, with magnets fixedly installed in the receiving grooves.

[0011] Optionally, a first water guide is fixedly installed on the upper water-blocking component, and a second water guide is fixedly installed on the end of the lower water-blocking component away from the handle of the target percutaneous endoscopic discectomy unit. The second water guide is connected to the water guide groove of the lower water-blocking component.

[0012] Optionally, both the upper and lower water-blocking components are made of rubber material.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] 1. Water flowing back from the working port on the target percutaneous endoscopic discectomy unit to the handle will be guided through the inclined end of the water channel to the water channels of the upper water baffle and the lower water channel, and then flow out through the first water channel and the second water channel respectively. This can prevent water on the handle from flowing onto the lens, thereby avoiding blurred vision, not affecting the surgical process, and reducing surgical safety risks.

[0015] 2. Both the upper and lower water-blocking components are mounted on the handle via suction cup grooves and magnets, making them easy to disassemble and install in different positions on the handle without affecting the surgical operation of the staff. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0020] This application discloses an external waterproof backflow device for percutaneous endoscopic discectomy.

[0021] Reference Figure 1 and Figure 2 A waterproof backflow device for percutaneous endoscopic discectomy is applied to a target percutaneous endoscopic discectomy. The target percutaneous endoscopic discectomy includes a body 4, a handle 5, and a lens 6. The body 4 is placed horizontally, with a working port 41 at the right end and a water inlet 42 at the upper end. The handle 5 is obliquely fixedly installed at the lower end of the body 4, and the lens 6 is threadedly installed at the end of the handle 5 away from the body 4.

[0022] A waterproof backflow device for a percutaneous endoscopic discectomy includes an upper water-blocking component 1 and a lower water-blocking component 2. Both the upper water-blocking component 1 and the lower water-blocking component 2 are semi-circular in shape. The upper water-blocking component 1 is located on the upper right part of the handle 5 of the target percutaneous endoscopic discectomy unit, and the lower water-blocking component 2 is located on the lower left part of the handle 5 of the target percutaneous endoscopic discectomy unit. The projections of the upper water-blocking component 1 and the lower water-blocking component 2 onto the diameter plane of the handle 5 of the target percutaneous endoscopic discectomy unit are circular. The ends of the upper water-blocking component 1 and the lower water-blocking component 2 closest to the handle 5 of the target percutaneous endoscopic discectomy unit are both open. The device features multiple suction cup slots and receiving slots, spaced apart. A magnet is fixedly installed within each receiving slot. The suction cup slots and magnets facilitate the installation of the upper and lower water-blocking components 1 and 2 at different heights on the handle 5 of the target percutaneous lumbar endoscope. Both the upper and lower water-blocking components 1 and 2 have water-guiding channels 3 at their tops. These channels alter the flow direction of water on the handle 5, causing the water to flow onto the ground. It should be noted that both the upper and lower water-blocking components 1 and 2 are made of rubber.

[0023] To facilitate the flow of water from the handle 5 of the target percutaneous endoscopic discectomy unit into the water channel 3, the walls of the water channels 3 of the upper and lower water-blocking components 1 and 2, near the handle 5 of the target percutaneous endoscopic discectomy unit, are both sloped.

[0024] To facilitate the outflow of water from the water channel 3, the two outlet ends of the upper water baffle 1 are fixedly equipped with the first water guide 11, and the lower water baffle 2 is fixedly equipped with the second water guide 21 at the end away from the handle 5 of the target percutaneous endoscopic discectomy. The second water guide 21 is connected to the water channel 3 of the lower water baffle 2.

[0025] The implementation principle of the waterproof backflow device for a percutaneous endoscopic discectomy in this application embodiment is as follows: the upper water-blocking component 1 is installed on the upper right part of the handle 5 of the target percutaneous endoscopic discectomy, and the lower water-blocking component 2 is installed on the lower left part of the handle 5 of the target percutaneous endoscopic discectomy. During the use of the target percutaneous endoscopic discectomy, if water drips from the working port 41 onto the handle 5 of the target percutaneous endoscopic discectomy, the water above the handle 5 of the target percutaneous endoscopic discectomy will flow into the water-guiding groove 3 of the upper water-blocking component 1 through the inclined groove wall of the water-guiding groove 3. The water in the water-guiding groove 3 will flow out through the first water-guiding component 11 and drip onto the ground or workbench. The water below the handle 5 of the target percutaneous endoscopic discectomy will flow into the water-guiding groove 3 of the lower water-blocking component 2 through the inclined groove wall of the water-guiding groove 3. The water in the water-guiding groove 3 will flow out through the second water-guiding component 21 and drip onto the ground or workbench, thereby preventing the water on the handle 5 of the target percutaneous endoscopic discectomy from flowing down the handle 5 onto the lens 6.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
