Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a flexible spinal endoscope device with air and water as dual media and a method for using the device. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] As an important development direction in the field of spinal surgery, spinal endoscopic surgery can be widely used in the surgical treatment of spinal degenerative diseases such as lumbar disc herniation, lumbar spinal stenosis, and cervical disc herniation.

[0004] Currently, the spinal endoscope commonly used in clinical practice is mainly rigid endoscope. A rigid endoscope is a straight, rigid tube whose end cannot rotate freely. During surgery, some target areas are "out of sight and out of reach", resulting in incomplete decompression or complications such as nerve damage.

[0005] The flexible spinal endoscope system disclosed in the prior art includes a working channel, an adjustment component, a channel component and a lens component. The working channel is a hose extruded from a soft polymer material, and a bending adjustment portion is provided at its front end. The channel component includes a channel tube, an instrument channel and an objective lens channel. A lens assembly is provided at the rear end of the channel component, and an objective lens is also provided at the front end of the bending adjustment portion. By arranging the bending adjustment portion at the front end of the working channel, a certain degree of freedom of adjustment can be performed, thereby overcoming the problem that some target areas of a rigid endoscope are "invisible and unreachable".

[0006] In the above scheme, the flexible spinal endoscope achieves a certain degree of freedom of steering through the bending adjustment part. However, the flexible spinal endoscope system of the above scheme is in an air medium. Operations in the air medium cannot effectively reduce tissue bleeding.

[0020] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0021] The present invention will be described in detail below with reference to the accompanying drawings.

[0022] Example 1 This embodiment discloses a flexible spinal endoscope device with air and water as dual media, such as Figure 1 As shown, it includes a lifting platform 1, the top surface of the lifting platform 1 is connected to the lower end of the universal ball head damping bracket 2, the upper end of the universal ball head damping bracket 2 is provided with a protective dustproof shell 3, and one side of the protective dustproof shell 3 is fixedly connected to the adjustment device 4; the flexible spinal endoscope 5 is arranged inside the protective dustproof shell 3, and the other side of the protective dustproof shell 3 is open, and the operator can adjust the flexible spinal endoscope 5 in the protective dustproof shell 3 from the open side.

[0023] It should be noted that, in this embodiment, the flexible spinal endoscope 5 is not improved. That is to say, the flexible spinal endoscope 5 in this embodiment adopts the existing technology or the flexible spinal endoscope mentioned in the background technology, such as Figure 2 As shown, it also includes a working channel 53, a channel assembly 51, a lens assembly 52, and an adjustment assembly. The front end of the working channel 53 is provided with a bending adjustment portion, and the front end of the bending adjustment portion is also provided with an objective lens. The channel assembly includes a channel tube, an instrument channel and an objective lens channel. The objective lens channel is provided inside the channel tube. The rear end of the channel assembly 51 is provided with a lens assembly 52. Figure 2 As shown, the rear end of the channel assembly 51 is provided with a lens assembly 52, and the front end of the channel assembly 51 is connected to the working channel 53. The channel assembly 51 of the flexible spinal endoscope 5 is clamped by the clamping device 31. The working channel 53 penetrates the adjustment device 4 from the protective dustproof shell 3 and extends out from the adjustment device 4.

[0024] In this embodiment, the lifting platform 1 adopts a Z-axis scissor lift platform, which is a common height adjustment component, such as the Z-axis scissor lift manual precision fine-tuning displacement platform produced by Beijing Paidiwei Co., Ltd. It is understandable that the specific model can be selected according to actual use needs.

[0025] The vertical position of the universal ball joint damping bracket 2 can be adjusted (i.e., height position adjustment) through the lifting platform 1. In this embodiment, the universal ball joint damping bracket 2 is a common universal ball joint damping bracket, which is generally composed of a ball joint rotating part, a ball joint fixing part, a damping adjustment mechanism, and a ball joint rotating part connecting rod. The ball joint rotating part is arranged in the ball joint fixing part, and a damping adjustment mechanism is arranged on the ball joint fixing part. The damping adjustment mechanism is used to change the friction between the ball joint rotating part and the ball joint fixing part. In this embodiment, the ball joint fixing part of the universal ball joint damping bracket 2 is arranged on the top surface of the lifting platform 1, and the ball joint rotating part connecting rod is connected to the protective dustproof shell 3. Figure 1 As shown, the angle of the protective dustproof housing 3 and the adjusting device 4 relative to the lifting platform 1 is adjusted by the universal ball joint damping bracket 2.

[0026] like Figure 1 、 Figure 2 As shown, a movable end is provided at the upper end of the protective dustproof shell 3. Specifically, a movable port having the same size as the movable end can be opened at the upper end of the protective dustproof shell 3 and connected to the movable end. The movable end of the protective dustproof shell 3 is opened and the flexible spinal endoscope 5 is set in the protective dustproof shell 3; the flexible spinal endoscope 5 is protected from above by the protective dustproof shell 3.

[0027] In some embodiments, the connection between the movable port and the movable end can be achieved by connecting with a hinge, a door nose or a door catch. For example, one side of the movable end is connected to one side of the movable port by a hinge, a door nose is set on the other side of the movable end, and a door catch is set on the other side of the movable port.

[0028] like Figure 2 As shown, the clamping device 31 clamps and holds the flexible spinal endoscope 5. The clamping device 31 includes a clamping column 32 and a clamping body 33. One end of the clamping column 32 is fixedly connected to the clamping body 33, and the other end is fixedly arranged on the inner bottom surface of the protective dustproof shell 3; the clamping body 33 can clamp and hold the channel assembly 51 of the flexible spinal endoscope 5, that is, the channel assembly 51 of the flexible spinal endoscope 5 is arranged inside the protective dustproof shell 3 through the clamping device 31.

[0029] In this embodiment, if Figure 2 、 Figure 3 As shown, the clamping body 33 includes a fixed ring 34, on which are evenly distributed multiple clamping clips 35. In this embodiment, two clamping clips 35 are provided. The clamping clips 35 include a threaded rod 36, which is connected to an arcuate clip 38 via a rotating bearing 37. The threaded rod 36 is threadedly connected to the fixed ring 34. When the threaded rod 36 is rotated, it moves toward the interior of the fixed ring 34, driving the arcuate clips 38 into the fixed ring 34, thereby clamping the channel assembly 51 of the flexible spinal endoscope 5 within the fixed ring 34.

[0030] It should be noted that a transfer rod 39 is provided between the arc-shaped clip 38 and the rotary bearing 37 , and the transfer rod 39 and the arc-shaped clip 38 are hinged to adapt to the outer wall size of the channel assembly 51 of the flexible spinal endoscope 5 .

[0031] It should be noted that the clamping device 31 is positioned within the protective dustproof housing 3 to ensure that the working channel 53 faces the adjustment device 4. In addition to clamping the flexible spinal endoscope 5, the clamping device 31 also has the function of clamping the channel assembly 51 of the flexible spinal endoscope 5 at different positions by changing the space between the arc-shaped clips 38, thereby changing the position of the flexible spinal endoscope 5 relative to the clamping device 31 and thus changing the length of the working channel 53 passing through the adjustment device 4. After extending out of the concentric tube 442, the working channel 53 can achieve a certain degree of freedom through the curved adjustment portion at the front end.

[0032] like Figure 1 、 Figure 2As shown, the adjustment device 4 includes a first damping bearing 41, which is connected to a second damping bearing 43 via two parallel guide rails 42. The guide rails 42 are fixedly connected to the inner rings of the first damping bearing 41 and the second damping bearing 43. The inner ring centers of the first damping bearing 41 and the second damping bearing 43 are co-level. A first through-hole is provided at the center of the inner ring of the first damping bearing 41 for passing through the working channel 53.

[0033] like Figure 2 As shown, a protection pipe 44 is fixedly provided at the center of the inner ring of the second damping bearing 43 , the protection pipe 44 passes through the inner ring of the second damping bearing 43 , and a water supply terminal 443 is provided between the first damping bearing 41 and the second damping bearing 43 .

[0034] like Figure 3 As shown, specifically, the protective pipe 44 includes a protective shell 441 fixedly connected to the inner ring of the second damping bearing 43, and a concentric tube 442 is passed through the protective shell 441 (the protective pipe 44 passes through the inner ring of the second damping bearing 43, which is achieved by the concentric tube 442). The length of the concentric tube 442 is greater than that of the protective shell 441. One end of the concentric tube 442 is located between the first damping bearing 41 and the second damping bearing 43, and this end is fixedly connected to a cube-shaped water supply end 443; the size of the water supply end 443 is greater than the diameter of the protective shell 441.

[0035] In this embodiment, the water delivery end 443 is similar to the sheath head structure of the existing double-valve direct water sheath, the difference is that, Figure 5 、 Figure 6 As shown, a connecting pipe 4431 is provided on each side of the water delivery end 443 in this embodiment, and one end of the connecting pipe 4431 away from the water delivery end 443 is connected to the water delivery pipe; the connecting pipes 4431 extend from one side of the water delivery end 443 into the interior of the water delivery end 443 and are connected to the side wall of the concentric tube 442; water is injected from the water delivery pipe and can be injected into the concentric tube 442.

[0036] like Figure 5 、 Figure 6 As shown, a concentric tube groove 4432 and a working channel groove 4433 are set in the inner center of the water supply end 443, a concentric tube 442 is fixed in the concentric tube groove 4432, and a working channel 53 is passed through the working channel groove 4433 and the concentric tube; it can be understood that the water supply end 443 and the concentric tube 442 are made as one piece.

[0037] It should be noted that the water pipe is connected to a pressurized water pipe, and a valve is provided on the water pipe to control the amount of water injected.

[0038] It should be noted that the protective shell 441 is a hard tube made of rigid material (such as stainless steel, titanium and other metal materials) and cannot be bent; while the concentric tube 442 is a soft tube made of flexible material (such as silicone, polyurethane and other polymer materials) and can be bent.

[0039] The inner diameter of concentric tube 442 is larger than the outer diameter of working channel 53, and the interior of concentric tube 442 is used to penetrate working channel 53. When water supply end 443 is connected to the water supply pipe and supplies water between concentric tube 442 and working channel 53, a water channel is formed, thereby placing the working channel in an aqueous environment. The advantages of performing the operation in an aqueous environment are: when the amount of bleeding is large, the water pressure can be used to reduce bleeding, and the water in the water channel between concentric tube 442 and working channel 53 can clean the objective lens at the front end of the working channel, thereby clearing the visual field of the objective lens. Alternatively, when the amount of bleeding is small, water can be omitted from the concentric tube 442, so that the working channel is in an air medium, simplifying the surgical procedure.

[0040] It is understandable that the use of a combination of air and water media can improve surgical efficiency, provide a clearer field of view, and reduce surgical risks.

[0041] like Figure 3 As shown, the protective housing 441 is a rigid tube that cannot be bent. After the working channel 53 extends out of the protective housing 441, the bending adjustment portion at its front end can be freely adjusted. However, if the working channel 53 extends too long, the water flowing out of the concentric tube 442 cannot effectively clean the working channel 53. In this case, it is necessary to adjust the extension length of the concentric tube 442 to ensure that the water flowing out of the concentric tube 442 can effectively clean the working channel 53.

[0042] like Figure 3 As shown, the concentric tube 442 can be moved and extended relative to the protective shell 441. Specifically, the side of the water delivery end 443 away from the second damping bearing 43 is fixedly connected to the movable slider 45.

[0043] like Figure 1 、 Figure 2 As shown, the movable slider 45 is disc-shaped and is arranged between the first damping bearing 41 and the second damping bearing 43, and has the same size as the outer ring of the first damping bearing 41 and the second damping bearing 43; a second through hole is provided at the center of the movable slider 45 for passing through the working channel 53; two sliding holes are provided on the movable slider 45 for cooperating with the guide rail 42, that is, the movable slider 45 can slide on the guide rail 42.

[0044] The diameters of the first through hole and the second through hole are consistent with each other, and are consistent with the diameter of the working channel 53 , so that the working channel 53 can pass through.

[0045] It should be noted that, in this embodiment, the side of the water delivery end 443 away from the second damping bearing 43 is fixedly connected to the movable slider 45 (for example, by bonding), so that when the movable slider 45 slides on the guide rail 42, it can drive the concentric tube 442 to move together, thereby changing the length of the concentric tube 442 extending out of the protective shell 441.

[0046] like Figure 3 As shown, when the movable slider 45 moves, the water delivery end at the end of the concentric tube drives the concentric tube to move out of the protective shell for a certain length, and the length of the concentric tube extending out of the protective shell also has a certain degree of freedom.

[0047] It needs to be explained that since the concentric tube 442 is connected to the movable slider 45, the movable slider 45 can drive the concentric tube 442 to rotate, and the movement of the movable slider 45 will also drive the concentric tube 442 to extend to different lengths at the end of the protective shell 441; and this length of the concentric tube 442 extending out of the protective shell will enable the concentric tube 442 to extend at different angles under the action of the protective shell.

[0048] By varying the extension lengths of the concentric tubes 442, the concentric tubes 442 can be extended at different angles, thereby providing a prerequisite for the working channel 53 of the flexible spinal endoscope 5 (for example, after the working channel 53 extends out of the protective housing 441, its own freedom of adjustment is limited, and a direction can be given in advance by the concentric tubes 442). Under this condition, the flexible spinal endoscope 5 itself can be rotated (angle adjusted) to achieve multi-angle, blind-spot-free observation at different positions to assist surgery.

[0049] It should be noted that the inner diameter of the protective shell 441 is equal to the outer diameter of the concentric tube 442. There will be a certain friction between the concentric tube 442 and the protective shell 441 when they move relative to each other, and the concentric tube 442 extending out of the protective shell 441 will bend. Generally, there is no need to set a separate locking device to lock the position of the movable slider 45.

[0050] like Figure 1 、 Figure 2 As shown, a follower-type protective housing 46 is connected between the first damping bearing 41, the movable slider 45, and the second damping bearing 43. A water pipe passes through the follower-type protective housing 46 between the movable slider 45 and the second damping bearing 43. It should be noted that the follower-type protective housing 46 is connected to the inner rings of the first damping bearing 41 and the second damping bearing 43. When the movable slider 45 rotates, the follower-type protective housing 46 and the inner rings of the first damping bearing 41 and the second damping bearing 43 rotate together.

[0051] In this embodiment, the follow-up protective housing 46 can be a flexible accordion-type protective cover that can be extended and retracted. When the movable slider 45 moves, it can drive the follow-up protective housing 46 to extend and retract, thereby protecting the various components between the two damping bearings from contamination.

[0052] By rotating the movable slider 45 , the inner rings and outer rings of the first damping bearing 41 and the second damping bearing 43 are driven to rotate relative to each other, driving the protection pipe 44 to rotate, thereby driving the working channel 53 to rotate together.

[0053] It should be noted that, in this embodiment, the flexible spinal endoscope 5 is for single use.

[0054] Example 2 This embodiment discloses a method for using a flexible spinal endoscope device using air and water as dual media, which utilizes the flexible spinal endoscope device using air and water as dual media disclosed in Example 1. The specific steps are as follows: First, the working channel 53 of the disposable flexible spinal endoscope 5 is passed through the clamping device 31 in the protective dustproof shell 3, and then the working channel 53 is passed through the adjustment device 4 until the working channel 53 passes through the protective pipe 44; It should be noted that in order to ensure that the working channel 53 can be inserted into the adjusting device 4 until the working channel 53 passes through the protective pipe 44, the movable slider 45 can be moved close to the first damping bearing 41 during the insertion, so that the working channel 53 can smoothly pass through the first through hole and the second through hole into the concentric tube.

[0055] Next, a disposable flexible spinal endoscope 5 is mounted on the clamping device 31; Next, place the lifting platform 1 at the desired location, adjust the height, and then adjust the universal ball head damping bracket 2 to adjust the spatial position of the protective dustproof housing 3 (i.e., adjust the spatial position of the protective pipe 44). Then, adjust the extension length or rotation angle of the concentric tube 442 to meet the surgical requirements. It should be noted that by flipping the moving slider 45, the position and angle of the concentric tube 442 can be adjusted; by moving the moving slider 45, the protruding length of the concentric tube 442 relative to the protective shell 441 can be changed; the protruding length of the concentric tube 442 determines the bending angle of the protruding length portion of the concentric tube 442; in layman's terms, the longer the protruding length, the larger the bending angle; according to actual needs, the moving slider 45 is moved, and during the movement, the follow-up protective shell 46 ensures that the internal structure will not be disturbed by the external environment.

[0056] After the concentric tube 442 is adjusted to the appropriate position, the clamping device 31 is adjusted to release the flexible spinal endoscope 5. The position of the flexible spinal endoscope 5 is then adjusted so that the working channel 53 extends beyond the concentric tube 442 by a set observation length to facilitate smooth surgical procedures. The clamping device 31 is then used again to secure the flexible spinal endoscope 5. In this embodiment, the observation length of the working channel 53 extending beyond the concentric tube 442 is set to be 7-9 mm.

[0057] During the operation, whether to inject water into the concentric tube 442 through the water pipe is determined based on the amount of bleeding or whether the field of view of the objective lens of the bending adjustment portion at the front end of the working channel is blurred.

[0058] It should be noted that, in this embodiment, the flexible spinal endoscope is placed in a protective dustproof casing, the working pipeline of the flexible spinal endoscope is passed through the protective pipeline of the adjustment device, a movable concentric tube is set between the protective pipeline and the working pipeline, and a water channel is formed between the concentric tube and the working pipeline, so that the flexible spinal endoscope can be in an air medium or a water medium. When in a water medium, it can reduce bleeding with the help of water pressure, and can also clean the working pipeline to keep the field of view of the objective lens clear.

[0059] In this embodiment, the concentric tube is first extended out of the protective tube to provide a leading direction for the working channel. The angle of the flexible spinal endoscope itself is then adjusted in this direction, so that multi-angle and blind-spot-free observation at different positions can be achieved to assist surgery.

[0060] Although the above describes the specific embodiments of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without any creative work are still within the scope of protection of the present invention.
