Abstract
Description
Technical Field
[0001] This utility model relates to the field of component spraying technology, and in particular to an integrated device for brain tissue separation and traction. Background Technology
[0002] In neurosurgery, the separation and traction of brain tissue are crucial for ensuring a clear surgical field, minimizing damage to surrounding tissues, and improving surgical precision. Separating brain tissue effectively avoids compression of important blood vessels and nerves, while traction helps to expand the surgical area, reducing pressure on brain tissue and preventing cerebral edema or injury. This integrated separation and traction technique utilizes precise mechanical forces to make surgical procedures more accurate and stable, reducing postoperative complications. Common traction devices include traction forceps, brain tissue traction devices, and miniature suction devices, which assist surgeons in precisely manipulating and adjusting brain tissue.
[0003] Common brain tissue separation and traction devices help surgeons protect brain tissue, improve clarity, and enhance operative precision during surgery by precisely controlling the application of force. Brain tissue separation devices typically use suction or minimally invasive clamps to gently separate brain tissue from surrounding structures, reducing direct contact and potential damage. Traction devices, through adjustable mechanical force or negative pressure systems, steadily stretch brain tissue, ensuring a wide surgical field, avoiding compression of vital nerves or blood vessels, and providing a stable operating platform. These devices provide precise and controllable force, making the surgical procedure safer and more effective.
[0004] Existing brain tissue separation devices are not compatible with brain tissue traction devices, resulting in an incoordination of separation and traction forces. This leads to uneven or excessive stretching of brain tissue, increasing the risk of injury. Secondly, the precision and smoothness of the surgical procedure decrease, requiring surgeons to frequently adjust different devices, increasing the difficulty and time required for the operation. Furthermore, existing brain tissue separation or traction devices lack the ability to collect fluid accumulated during surgery, causing this fluid to obstruct the surgical field and reduce operational accuracy. The accumulation of fluid not only increases pressure on brain tissue, leading to localized cerebral edema, but also compresses important nerves or blood vessels, increasing the risk of intraoperative bleeding or injury. Therefore, this paper proposes an integrated brain tissue separation and traction device to address these issues. Utility Model Content

[0011] As a further description of the above technical solution: the pneumatic assembly includes an empty pipe, which is fixedly connected to the outside of the liquid collection pipe. A push rod is slidably connected inside the empty pipe. An electric push rod is fixedly connected to the left side of the push rod.

[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, by pushing the sliding block, the sliding block pulls the metal wire, causing the mounting block connected to the metal wire to move the upper clamp and the lower clamp. Because of the limiting grooves opened in the rotating shaft and limiting shaft between the upper clamp and the lower clamp, the lower clamp and the rotating shaft can clamp and pull the brain tissue that needs to be separated. The sharp edges of the upper clamp and the rotating shaft on the left side complete the separation of the brain tissue, reduce damage to the surrounding nerve structures, reduce the risk of postoperative complications, shorten the recovery time, and improve the surgical effect. It shows significant advantages, especially in handling complex cases such as tumor resection or cerebrovascular lesions.
[0017] 2. In this utility model, the electric push rod is activated, pushing the push rod to move inside the hollow tube. The hollow tube and the push rod are in contact, creating a negative pressure inside the hollow tube. Then, the effusion tube draws out the effusion. At the same time, the protective shell connected to the bottom of the effusion tube fixes and supports multiple support blocks and a sliding shaft. The negative pressure pushes the funnel plug to slide, making room for the effusion to pass through. When the push rod increases the pressure inside the hollow tube, the funnel plug moves upward, blocking the channel, while the bottom funnel plug slides down, allowing the effusion to flow out of the device through the effusion tube. This reduces the risk of complications during the operation, promotes postoperative recovery, and improves the patient's prognosis, especially in the treatment of hydrocephalus or cerebral hematoma.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figures 1 to 3 One embodiment of this utility model is a brain tissue separation and traction integrated device, which includes a pipe 1, which is the main part of the device and connects and carries multiple liquid aspiration mechanisms and observation components. It provides a channel for aspirating cerebral fluid and connecting devices for different components. The inside of the tube 1 is detachably connected to an aspiration mechanism for aspirating cerebral fluid, preventing the cerebral fluid from affecting the viewing of the lesion and reducing the pressure of separating brain tissue. The left side of the tube 1 is detachably connected to a support block 6, which provides stable support and ensures that the tube 1 and the traction separation mechanism remain fixed during the operation. The left side of the support block 6 is also detachably connected to a traction separation mechanism, which is used to pull and separate brain tissue during the operation, reducing damage to nerves and blood vessels and improving the precision of the surgical operation. The inside of the support block 6 is fixedly connected to an observation component for real-time observation of the brain tissue in the surgical area, ensuring that the doctor can clearly see the separation of brain tissue and the process of aspirating fluid. The right side of the tube 1 is fixedly connected to a splicing pipe 2, which serves as an intermediate part connecting the tube body and the handle 3. At the same time, the tube 1 is connected to the splicing pipe 2 by threads, and the inside of the splicing pipe 2 is fixedly connected to the handle 3, providing a gripping position for using the device, making it easier to operate when using the device.
[0026] The traction separation mechanism includes a sliding block 17, which serves as the power component of the traction separation mechanism. It operates the clamping mechanism by sliding the metal wires 9, thereby completing the traction and separation of brain tissue. The sliding block 17 is slidably connected inside the handle 3. Two metal wires 9 are fixedly connected to the left side of the sliding block 17, existing as connectors between the sliding block 17 and the mounting block 10. They are threaded to the mounting block 10, making disassembly easier when removing the clamping mechanism. The tops of both metal wires 9 are threaded to the mounting blocks 10, providing installation positions for the metal wires 9 and for a rotating block rotatably connected inside the mounting block 10. A rotating shaft 11 is rotatably connected inside the mounting block 10. The upper clamp 13 and lower clamp 12 can clamp the brain tissue with the help of the limiting groove inside the limiting shaft 8. The upper clamp 13 is rotatably connected to the outside of the rotating shaft 11, and the lower clamp 12 is fixedly connected to the outside of the rotating shaft 11. The upper clamp 13 works with the lower clamp 12 to complete the traction and separation of brain tissue. At the same time, the rounded corners and sharp edges of the upper clamp 13 and lower clamp 12 make the separation and traction of brain tissue easier. The mounting block 10 is slidably connected to a support component to provide support for the upper clamp 13 and lower clamp 12 and ensure their stability during operation. The observation component includes a data cable 5 to transmit data captured by the camera, allowing doctors to view the lesion during use. The data cable 5 is fixed. A camera is fixedly connected inside the data cable 5, with a camera at the top of the data cable 5 to capture images of the lesion, making separation and traction more accurate. The camera is fixedly connected to the top of the support block 6. The support assembly includes an extension shaft 7 and an extension limiting shaft 8. The extension shaft 7 is fixedly connected to the top of the support block 6, and the limiting shaft 8 is detachably connected to the top of the extension shaft 7, providing installation positions for the upper clamp 13 and the lower clamp 12. At the same time, the limiting groove can complete the opening and closing action when the upper clamp 13 and the lower clamp 12 move. The limiting shaft 8 has a limiting groove inside, and the upper clamp 13 and the lower clamp 12 are slidably connected in the limiting groove. Sliding grooves are provided on both sides of the limiting groove, allowing the mounting block 10 to slide. Next, the mounting block 10 is slidably connected in the sliding groove. The lower clamp 12 and the upper clamp 13 are fixedly connected to a fixing block 14, which provides a fixed position for the return spring 15, making it easier for the return spring 15 to apply force. The top of the fixing block 14 is fixedly connected to the return spring 15, which facilitates the opening and closing of the upper clamp 13 and the lower clamp 12 and makes it easier to operate. The return spring 15 is fixedly connected to the top of the upper clamp 13. The edges of the upper clamp 13 and the lower clamp 12 near the left metal wire 9 are made with sharp angles, while the edges of the upper clamp 13 and the lower clamp 12 near the right metal wire 9 are made with rounded corners. The bottom of the lower clamp 12 near the metal wire 9 is provided with an air cushion to prevent damage to the separated brain tissue.
[0027] Reference Figure 1 , Figure 3 , Figure 4 The aspiration mechanism includes a effusion tube 16, which is connected to the pipe 1 to prevent it from moving arbitrarily and thus avoiding damage to brain tissue. The effusion tube 16 is slidably connected inside the support block 6. Two protective shells 21 are fixedly connected to the outside of the effusion tube 16, providing protection for the support blocks, support rings 22, and sliding shafts 23 fixedly connected inside the protective shells 21, and preventing leakage of the aspirated fluid. Multiple support blocks 28 are fixedly connected inside each of the protective shells 21, providing support for the support rings 22 and preventing the sliding shafts 23 from shifting during sliding. Support rings 22 are fixedly connected to the top of the multiple support blocks 28, providing support for the sliding shafts 23. The sliding shafts 23 are slidably connected inside the support rings 22 to prevent the funnel plugs 20 from shifting during sliding and to fix the sliding range of the funnel plugs 20. The funnel plugs 20 are fixedly connected to the top of the sliding shafts 23, controllably blocking the effusion tube 16 and completing the aspiration of the fluid. For liquid extraction, a pneumatic assembly is fixedly connected between the two protective shells 21 to drive the liquid collection tube 16, automating the liquid collection process and ensuring operational accuracy and efficiency. The pneumatic assembly includes an empty tube 19, which acts as a cylinder. With the sliding of the push rod 24, the cylinder can form negative or high pressure to complete the extraction of liquid. The empty tube 19 is fixedly connected to the outside of the liquid collection tube 16. The push rod 24 is slidably connected inside the empty tube 19 and is pushed or pulled by the electric push rod 25 to pressurize the cylinder. The electric push rod 25 is fixedly connected to the left side of the push rod 24 to provide power to the pneumatic assembly and make the pneumatic assembly more stable. The top of the electric push rod 25 is detachably connected to a fixing block 26 to provide an installation position for the electric push rod 25. The fixing block 26 is fixedly connected to the bottom of the pipe 1. The outside of the pipe 1 is threaded, and the pipe 1 is threadedly connected to the splicing pipe 2. A soft pad 4 is fixedly connected to the left side of the handle 3 to make it more comfortable to use.
[0028] Working Principle: During the procedure, the surgeon first positions the device's tube 1 in the target brain region. Tube 1 is connected to the splicing tube 2 via threads, and the splicing tube 2 is connected to the handle 3, providing stable support for the operation. A soft pad 4 is fixed to the left side of the handle 3 to ensure the surgeon's comfort during operation. At this time, the device's aspiration mechanism begins to work. The effusion tube 16, controlled by the pneumatic assembly, aspirates fluid from the brain. The effusion tube 16 is slidably connected inside the support block 6 to ensure it does not move arbitrarily, while the protective shell 21 prevents liquid leakage. The pneumatic assembly, controlled by the push rod 24 and the electric push rod 25, generates negative or high pressure inside the empty tube 19, effectively aspirating the fluid and ensuring operational accuracy. When negative pressure is generated, the funnel plug 20 at the top blocks the effusion tube to prevent backflow of the fluid, while the funnel plug 20 at the bottom and the sliding shaft 23 slide downwards along the support ring 22, creating space for the fluid to flow out of the device.
[0029] Simultaneously, the traction separation mechanism begins to operate. The sliding block 17 slides inside the handle 3, controlling the movement of the clamping mechanism through the traction of the metal wire 9. The upper clamp 13 and lower clamp 12 achieve precise traction and separation of brain tissue through the rotation of the rotating shaft 11. The rotating block and limiting shaft 8 ensure the stability of the clamping components through the limiting groove, avoiding unnecessary damage. The rotating shaft 11, support assembly, and return spring 15 within the mounting block 10 work together to ensure the clamping device can stably perform traction and separation of brain tissue. Simultaneously, the return spring 15 assists the upper clamp 13 and lower clamp 12 in completing automatic reset actions, ensuring surgical precision.
[0030] The camera within the observation unit monitors the brain tissue in real time, transmitting the data to the surgeon's console. This ensures the surgeon can clearly view the separation of brain tissue and the drainage of fluid throughout the entire procedure. This process is facilitated by data cable 5, ensuring the stability and real-time nature of the data transmission.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
