Description

Technical Field

[0001] This utility model relates to the field of endoscopy technology, and more specifically, to a flexible neuroendoscopy endoscope. Background Technology

[0002] As is well known, traditional intracranial surgery involves making an incision in the brain and using a microscope for observation and treatment. However, this is quite invasive, and because the insertion part of a rigid endoscope cannot bend, it creates blind spots, making it impossible to fully visualize lesions and thus limiting the surgery. Endoscopy, on the other hand, is a medical auxiliary technique that allows doctors to perform tasks that previously required large incisions with only small incisions. Furthermore, due to the magnification effect of the endoscope, doctors can operate more accurately. Currently, it is widely used in the examination and treatment of diseases of the gastrointestinal tract, pancreas, biliary tract, abdominal cavity, respiratory tract, and urinary tract, but it has not yet been widely used in neurosurgery.

Detailed Implementation

[0031] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0032] Example

[0033] Please refer to Figures 1-12 This embodiment provides a flexible neuroendoscopy, including a handle 1, an insertion tube 2, and a curved serpentine structure at the end of the insertion tube 2 away from the handle 1. A protective sleeve 9 is fitted over the curved serpentine structure. A tip 3 is located at the end of the curved serpentine structure away from the insertion tube 2, and a camera 4 is mounted on the tip 3. The curved serpentine structure is hollow inside, and two pull wires 5 are connected to each other on the inner sidewall of the front end of the curved serpentine structure. The pull wires 5 pass through the insertion tube 2 and extend into the handle 1. The handle 1 is equipped with a traction component for pulling the pull wires 5.

[0034] The handle 1 in this embodiment is for medical personnel to grip. The handle 1 is ergonomically designed, non-slip, and easy for medical personnel to hold. The insertion tube 2 is made of heat-treated metal that can be bent at any angle, possessing a certain degree of hardness. The required angle can be pre-adjusted, facilitating the user's access to any difficult location. The curved snake-like structure in this embodiment can be bent by pulling two pull wires 5 separately using the traction component. By pulling the first section of the curved snake-like structure with the two pull wires 5 respectively, a small-range two-way bending of 90° in both directions can be achieved. It features an ultra-small bending radius, which can be set to 13 mm, allowing access to multiple locations within a small space. The flexible structure of the curved snake-like structure allows for two-way turning of the front curved snake-like structure, facilitating better observation and access to the lesion location, and enabling real-time image transmission to the back end. The curved snake-like structure is externally covered by a protective sleeve 9 made of TPU material, providing sealing and lubrication.

[0035] The tip 3 of this embodiment is made of transparent material. An LED cold light source can be installed inside the tip 3 for illumination during use. A camera 4 capable of real-time image transmission is installed inside the tip 3. Both the camera 4 and the LED cold light source can be connected via wires 27. The wires 27 pass through the insertion tube 2 and the handle 1 and connect to a computer or other display device, thus enabling real-time image transmission for medical personnel to view. The handle 1 of this embodiment can be equipped with corresponding control buttons 26, which are electrically connected to the camera 4. Pressing the control buttons 26 enables functions such as freeze, photographing, and recording. The tip 3 of this embodiment adopts a bullet-shaped design, with no sharp edges to prevent damage to brain tissue. Its downward-piercing bullet-shaped design makes it easier to enter sheaths and other locations, facilitating surgical procedures for medical personnel.

[0036] The flexible neuroendoscopy provided in this application is designed for neurosurgical procedures. In use, the endoscope is inserted into the patient's skull through a small incision at its tip. Two pull wires 5 are used to pull the curved serpentine bone, allowing for bending. Surgical intervention is performed by observing video information transmitted from the camera 4. This flexible neuroendoscopy features a simple structure, ease of use, minimal invasiveness, and easy bending. It provides comprehensive visualization of the affected area, offering complete imaging and enabling simultaneous surgical procedures. It incorporates multiple functions including illumination, surgery, irrigation, and suction, providing a safer and more reliable technique for neurosurgery, improving surgical quality, and reducing complications.

[0037] like Figures 5-9 As shown, in some embodiments, the curved snake bone includes a head snake bone 6, a tail snake bone 7, and a plurality of connecting snake bones 8 located between the head snake bone 6 and the tail snake bone 7. A pull wire 5 is connected to the head snake bone 6, and the plurality of connecting snake bones 8 are rotatably connected in sequence to form a series structure. One end of the series structure is rotatably connected to the head snake bone 6, and the other end of the series structure is rotatably connected to the tail snake bone 7. The tip 3 is provided on the head snake bone 6, and the insertion tube 2 is connected to the tail snake bone 7.

[0038] One end of any connecting snake bone 8 is provided with a rotating disk 10, and the other end of any connecting snake bone 8 is provided with a rotating slot 11. The rotating disk 10 of one connecting snake bone 8 is rotatably embedded into the rotating slot 11 of the adjacent connecting snake bone 8. In this embodiment, the head snake bone 6 is provided with a rotating slot 11, and the tail snake bone 7 is provided with a rotating disk 10. One end of this series structure is rotatably disposed in the rotating slot 11 of the head snake bone 6 via the rotating disk 10, and the rotating disk 10 of the tail snake bone 7 is rotatably disposed in the rotating slot 11 of the other end of the series structure. In this way, the angle can be adjusted between the head snake bone 6 and the connecting snake bone 8, and between the tail snake bone 7 and the connecting snake bone 8.

[0039] This utility model sets up a head snake bone 6, a tail snake bone 7 and multiple connecting snake bones 8, and achieves rotational connection through the cooperation of a rotating disk 10 and a rotating slot 11. This makes it easy to adjust the angle of the bending snake bone by pulling the pull line 5, which is convenient to operate.

[0040] like Figures 1-3 , Figure 6 As shown, in some embodiments, the tip 3 is provided with a tip outlet 12, and the tip 3 is provided with an operating tube 13 communicating with the tip outlet 12. The operating tube 13 is sealed to the tip outlet 12, and the operating tube 13 passes through the insertion tube 2 and extends into the handle 1. The handle 1 is provided with an instrument channel port 14 communicating with the operating tube 13. By providing the tip outlet 12 and the instrument channel port 14, this utility model allows instruments for diagnosing or treating patients to be inserted through the instrument channel port 14 during use. After the instrument is inserted into the instrument channel port 14, it can reach the position of the tip outlet 12 through the operating tube 13, thereby facilitating access to the patient's surgical site.

[0041] like Figures 1-3 As shown, in some embodiments, the handle 1 is provided with a suction control valve 15, which is connected to the operating pipe 13 via a connecting pipe 17. The handle 1 is also provided with an injection control valve 16, which is connected to the operating pipe 13 via a connecting pipe 17.

[0042] This utility model, by setting a suction control valve 15, allows the suction machine to be connected through the suction control valve 15 during use. At this time, the instrument channel port 14 is closed, the suction control valve 15 is opened, and the suction machine is turned on. Suction can be performed from the tip outlet 12 to the rear. With the bending of the curved snake bone, liquids and small solids from multiple locations can be sucked out.

[0043] This invention features an injection control valve 16. In use, the pressurized liquid to be injected can be connected through the injection control valve 16. At this time, the instrument channel port 14 is closed, and the injection control valve 16 is opened. The pressurized liquid can be injected into the patient's lesion site through the injection control valve 16, the operating tube 13, and the tip outlet 12 in sequence.

[0044] like Figures 1-3 , Figures 10-12As shown, in some embodiments, the pulling assembly includes a drive disc 18 rotatably disposed within the handle 1. The ends of the two pull wires 5 furthest from the curved snake-like structure are both wound around the drive disc 18 in opposite directions. A friction locking plate 19 is fixedly disposed within the handle 1, and a drive shaft 20 is rotatably inserted through the friction locking plate 19. The friction locking plate 19 is used to lock the drive disc 18 after it has tightly abutted against the friction locking plate 19. One end of the drive shaft 20 is connected to the drive disc 18, and the other end passes through the handle 1 and is located outside the handle 1. A wrench 21 is provided on the drive shaft 20 and is located outside the handle 1. The wrench 21 is slidably sleeved on the drive shaft 20. In this embodiment, the wrench 21 is used to drive the drive shaft 20 and the drive disc 18 to rotate simultaneously during rotation. Figure 12 As shown, the outer wall of the drive shaft 20 is provided with a limiting groove. The wrench 21 is slidably sleeved in the limiting groove of the drive shaft 20. The wrench 21 can only slide along the axial direction of the drive shaft 20 and cannot rotate relative to the drive shaft 20. The end of the drive shaft 20 located outside the handle 1 is provided with a screw hole 22; it also includes a locking knob 23, which is provided with a screw 24. The screw 24 is inserted into the screw hole 22 and threadedly connected to the drive shaft 20.

[0045] In this embodiment, the drive turntable 18 is used to pull the pull cable 5 during rotation. When the drive turntable 18 rotates clockwise, it pulls the first pull cable 5, causing the curved snake bone to rotate and adjust its angle. At this time, the second pull cable 5 is in a relaxed state. When the drive turntable 18 rotates counterclockwise, it pulls the second pull cable 5, causing the curved snake bone to rotate and adjust its angle. At this time, the first pull cable 5 is in a relaxed state. This facilitates adjustment of the bending angle of the curved snake bone in both directions.

[0046] By setting the drive turntable 18 and the locking knob 23, when it is necessary to adjust the bending angle of the curved snake bone, the locking knob 23 is loosened. At this time, the medical staff holds the handle 1 and turns the wrench 21 by their fingers. The wrench 21 drives the drive shaft 20 and the drive turntable 18 to rotate at the same time. In this way, the bending angle of the curved snake bone can be adjusted by pulling the pull wire 5 through the rotating drive turntable 18.

[0047] After adjustment, the medical staff keeps the wrench 21 still with their fingers and tightens the locking knob 23 with their fingers. Since the screw 24 is threadedly connected to the drive shaft 20, the rotating screw 24 can drive the drive shaft 20 to move towards the locking knob 23. The moving drive shaft 20 drives the drive disc 18 to move towards the friction locking plate 19 and tightly abut against the side wall of the friction locking plate 19. This makes it easy to friction lock the drive disc 18, so that the curved snake bone can be kept at the adjusted bending angle without the need for the medical staff to keep the wrench 21 still, saving the medical staff's physical strength.

[0048] Optionally, such as Figures 10-12 As shown, the drive shaft 20 of this embodiment is fitted with a spring 25. The spring 25 is located inside the handle 1. One end of the spring 25 abuts against the drive turntable 18, and the other end of the spring 25 abuts against the inner side wall of the handle 1. Thus, after loosening the locking knob 23, the spring 25 can apply a spring force to the drive turntable 18 to move the drive turntable 18 away from the friction locking piece 19, which is convenient for subsequent adjustment by rotating the wrench 21.

[0049] Furthermore, unless otherwise explicitly specified or limited, the terms "installation" and "connection" in this application embodiment should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.
