Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a mounting bracket and a suction device. Background Technology

[0002] During neuroendoscopic surgery, neurosurgeons typically hold the neuroendoscope in their left hand and the surgical instruments, such as suction devices, curettes, and bipolar electrocautery tools, in their right. For delicate procedures, an assistant is needed to hold the suction device or neuroendoscope, requiring two-, three-, or even four-handed operation. Due to the limited space in the surgical aisle, interference between instruments frequently occurs if the assistant is not skilled or lacks coordination.

[0003] While Professor Froelich's unique "chopstick technique" has solved the problem of two-person coordination, this technique has a high learning cost and is difficult to operate. Furthermore, it relies on the nostrils as a fulcrum, making it even more difficult to operate in non-nasal surgeries. The compatible suction device also requires blocking the side openings, sacrificing negative pressure control and increasing surgical risks. These drawbacks hinder its rapid widespread adoption and restrict surgical safety. Therefore, an electronic visual suction endoscope that can be operated with one hand, precisely adjusts negative pressure, and is easy for doctors to learn is essential.

[0004] This device features an integrated design, overcoming the drawbacks of the "chopstick technique," which is difficult to master, relies on a specific fulcrum, and has inconvenient negative pressure control of the suction device. It allows for single-handed operation of three core functions: suction, visualization, and irrigation. The suction tube and endoscope are simultaneously flexible, retaining the side hole of the suction device for precise negative pressure adjustment, and eliminating reliance on a specific fulcrum. This makes it suitable for various surgical scenarios, including transnasal and intracranial hemorrhage procedures. Doctors do not need to learn complex techniques; they can quickly master the device using traditional suction tube operation methods, significantly reducing the learning curve and contributing to the popularization and standardization of neuroendoscopic technology, ultimately achieving the surgical goal of "seeing what is in sight and achieving hand-eye coordination." Summary of the Invention

The first end of the second hose extends to the handle on the suction tube; after the connector is installed on the suction tube, the second end of the second hose can be connected to the first mounting through hole so that the wire located between the handle and the mounting bracket is wrapped inside the second hose.

[0017] Optionally, the length of the second hose is greater than the length of the first hose, and the second end of the second hose is located on the extension line of the first hose, so that the position of the second hose located at the end of the mounting bracket and the first hose away from the handle can move with the mounting bracket along the length direction of the suction tube and rotate with the mounting bracket axially rotating relative to the suction tube.

Detailed Implementation

[0026] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The following description, with reference to the accompanying drawings, describes some embodiments of the mounting bracket and suction device provided according to the present invention.

[0028] See Figures 1 to 4 ,and Figure 8 and Figure 9 An embodiment of the present invention provides a mounting bracket 100 applied to a suction device. The mounting bracket 100 includes a connecting portion 110 and a mounting portion 120. The connecting portion 110 is detachably connected to the suction tube 200 of the suction device. The mounting portion 120 is fixed on the connecting portion 110 and has a first mounting through hole 121 for mounting a camera. After the connecting portion 110 is mounted on the suction tube 200, the end face of the first mounting through hole 121 near the suction port of the suction tube 200 gradually tilts towards the axis of the suction tube 200 along a direction from away from to near the suction port of the suction tube 200. The included angle between the end face of the first mounting through hole 121 near the suction port of the suction tube 200 and the axis corresponding to the portion of the suction tube 200 connected to the connecting portion 110 is 40° to 90°.

[0029] Here, the connecting part 110 and the mounting part 120 can be an integrally formed structure.

[0030] The included angle between the first mounting through hole 121 near the suction port end face of the suction tube 200 and the axis corresponding to the part of the suction tube 200 connected to the connecting part 110 is one of 40°, 50°, 60°, 70°, 80°, and 90°, preferably 60°.

[0031] In this embodiment, by mounting a camera on the first mounting through hole 121 of the mounting part 120 and then detachably mounting the connecting part 110 on the suction tube 200, the endoscopic and suction functions of the suction device are integrated into the suction tube 200, allowing for operation of both functions with one hand. Simultaneously, after the connecting part 110 is mounted on the suction tube 200, the end face of the first mounting through hole 121 near the suction port of the suction tube 200 is aligned from the point away from the suction port to the point closer to the suction port. The direction gradually tilts towards the axis of the suction tube 200, and the angle between the end face of the first mounting through hole 121 near the suction port of the suction tube 200 and the axis corresponding to the part of the suction tube 200 connected to the connecting part 110 is 40° to 90°. This can further expand the field of view of the camera, so that the operation direction of the suction tube 200 is consistent with the image display direction in the camera, and the camera can also capture images of a larger area in front of the suction tube 200, thereby enabling the doctor to observe a larger area of ​​the affected area.

[0032] In some possible embodiments, the mounting part 120 is further provided with a second mounting through hole 122; the second mounting through hole 122 is used to install a rinsing nozzle 300, which is used to spray cleaning liquid onto the surface of the camera.

[0033] Here, the cleaning liquid can be water.

[0034] Since blood can easily adhere to the surface of the camera when the suction tube 200 suctions blood, cerebrospinal fluid or fragmented tissue from the patient's surgical site, in order to clean the dirt on the camera surface, a second mounting through hole 122 is opened on the mounting part 120 so that a rinsing nozzle 300 for spraying cleaning liquid on the camera surface can be installed on the mounting part 120, thereby achieving cleaning of the camera surface by the rinsing nozzle 300.

[0035] In some possible embodiments, the mounting portion 120 is further provided with a third mounting through hole 123; the third mounting through hole 123 is detachably connected to the flushing fluid system; see also Figure 3After the third mounting through-hole 123 is connected to the irrigation fluid system, the third mounting through-hole 123 is used to spray the irrigation fluid in the irrigation fluid system onto the surgical surface.

[0036] In order to rinse the surgical surface, a third mounting through hole 123 is provided on the mounting part 120 so that the third mounting through hole 123 can be detachably connected to the rinsing fluid system. After the third mounting through hole 123 is connected to the rinsing fluid system, the third mounting through hole 123 sprays the rinsing fluid in the rinsing fluid system onto the surgical surface, thereby rinsing the surgical surface through the third mounting through hole 123.

[0037] In some possible embodiments, the third mounting through hole 123 is also detachably connected to the air supply module; after the third mounting through hole 123 is connected to the air supply module, the third mounting through hole 123 is used to install the air blowing nozzle 400, which is used to blow air to clean the surface of the camera.

[0038] In order to blow off dirt adhering to the camera surface, or to dry the cleaning liquid adhering to the camera surface, a third mounting through hole 123 is provided on the mounting part 120 so that an air nozzle 400 for air cleaning the camera surface can be installed on the mounting part 120, thereby realizing air cleaning of the camera surface through the air nozzle 400.

[0039] In some possible embodiments, the connecting part 110 includes a clamping body that can be clamped and connected to the suction tube 200; after the clamping body is clamped onto the suction tube 200, at least a portion of the inner wall of the clamping body is in contact with the outer wall of the suction tube 200.

[0040] Here, the clamping body may include an arc-shaped plate and an opening, the opening being arranged along the length direction of the arc-shaped plate, and the width of the opening being smaller than the diameter of the suction tube 200. The mounting part 120 is connected to the side of the clamping body away from the opening, wherein the clamping body is made of elastic plastic.

[0041] When clamping the clamping body onto the suction tube 200, the opening is aligned with the outer wall of the suction tube 200, and the length direction of the opening is parallel to the length direction of the suction tube 200. Then, the entire arc-shaped plate is pressed up and down onto the suction tube 200 to clamp the arc-shaped plate onto the suction tube 200. After the arc-shaped plate is clamped onto the suction tube 200, the center of the cross-section of the arc-shaped plate is located on the axis of the suction tube 200.

[0042] In addition, when clamping the clamping body onto the suction tube 200, the suction tube 200 can also be inserted into the clamping body to clamp and install the clamping body onto the suction tube 200.

[0043] In this way, by clamping the clamp onto the suction tube 200, at least a portion of the inner wall of the clamp is made to fit against the outer wall of the suction tube 200, so that the clamp can be stably installed on the suction tube 200.

[0044] In this embodiment, by selecting the connecting part 110 as a clamping body that can be clamped and connected to the suction tube 200, and after the clamping body is clamped on the suction tube 200, at least a portion of the inner wall of the clamping body is in contact with the outer wall of the suction tube 200, it is possible to detachably connect the connecting part 110 to the suction tube 200 while also enabling the connecting part 110 to be stably installed on the suction tube 200.

[0045] In some possible embodiments, after the clamping body is clamped onto the suction tube 200, the clamping body can rotate axially relative to the suction tube 200 to adjust the mounting angle of the camera on the suction tube 200.

[0046] Here, after the clamping body is clamped onto the suction tube 200, by allowing the clamping body to rotate axially relative to the suction tube 200, the camera can rotate together with the clamping body to adjust the installation angle of the camera on the suction tube 200. This achieves the purpose of adjusting the camera angle by rotating it coaxially around the suction tube 200, so that the direction of the camera is adjusted so that the image captured by the camera and displayed on the monitor is consistent with the doctor's visual direction.

[0047] In some possible embodiments, after the clamping body is clamped onto the suction tube 200, the clamping body can move along the length of the suction tube 200 to adjust the mounting position of the camera on the suction tube 200.

[0048] Here, after the clamping body is clamped onto the suction tube 200, by moving the clamping body along the length of the suction tube 200, the camera can be moved along the length of the suction tube 200 together with the clamping body, adjusting the installation position of the camera on the suction tube 200, and realizing the adjustment of the distance between the camera and the suction port on the suction tube 200, so that the doctor can adjust the installation position of the camera on the suction tube 200 according to the required field of view of the surgical site.

[0049] See Figures 5 to 11 Another embodiment of the present invention provides an aspirator, including the mounting bracket 100 as in any of the above embodiments.

[0050] Since the suction device of this embodiment includes any of the mounting brackets 100 in the first aspect described above, it has the beneficial effects of any of the above embodiments, which will not be repeated here.

[0051] In some possible embodiments, the suction device further includes a hose assembly 500, which includes a first hose 510 and a second hose 520. The first hose 510 is fitted onto the suction tube 200. At least a portion of the outer wall of the second hose 520 is connected to the outer wall of the first hose 510, and the axial direction of the portion of the second hose 520 connected to the first hose 510 is the same as the axial direction of the first hose 510. A wire for connecting to a camera is threaded inside the second hose 520. A first end of the second hose 520 extends to a handle 600 on the suction device. After the connecting portion 110 is installed on the suction tube 200, a second end of the second hose 520 can be connected to a first mounting through hole 121 so that the wire located between the handle 600 and the mounting bracket 100 is wrapped inside the second hose 520.

[0052] Here, both the first hose 510 and the second hose 520 can be made of silicone.

[0053] In this embodiment, by fitting the first flexible tube 510 onto the suction tube 200, and then connecting at least a portion of the outer wall of the second flexible tube 520 to the outer wall of the first flexible tube 510, when the connecting portion 110 in the mounting bracket 100 rotates on the suction tube 200, the first flexible tube 510 and the second flexible tube 520, which are of the same length, can twist on the suction tube 200 as the connecting portion 110 rotates. This causes the wire wrapped inside the second flexible tube 520 to twist along with the second flexible tube 520 on the outer wall of the suction tube 200. Therefore, when it is necessary to adjust the mounting angle of the camera on the suction tube 200, by rotating the connecting portion 110 installed on the suction tube 200, the wire wrapped inside the second flexible tube 520 twists along with the second flexible tube 520 on the suction tube 200. (See also...) Figure 11 This allows the connecting part 110 to rotate smoothly on the suction tube 200. At the same time, the first end of the second hose 520 extends to the handle 600 on the suction device. After the connecting part 110 is installed on the suction tube 200, the second end of the second hose 520 can be connected to the first mounting through hole 121 so that the wire located between the handle 600 and the mounting bracket 100 is wrapped in the second hose 520. This ensures that even if the wire located between the handle 600 and the mounting bracket 100 is twisted on the suction tube 200, it will remain covered by the second hose 520 to avoid damage caused by the wire being exposed.

[0054] In some possible implementations, see [link to relevant documentation]. Figure 7 and Figure 10The length of the second hose 520 is greater than the length of the first hose 510, and the second end of the second hose 520 is located on the extension line of the first hose 510, so that the position of the second hose 520 located at the end of the mounting bracket 100 and the first hose 510 away from the handle 600 can move with the mounting bracket 100 along the length direction of the suction tube 200 and rotate with the mounting bracket 100 axially rotating relative to the suction tube 200.

[0055] Here, the length of the second hose 520 is greater than the length of the first hose 510, and the second end of the second hose 520 is located on the extension line of the first hose 510. When the mounting bracket 100 moves towards the handle 600, the position corresponding to the second hose 520 at the end of the mounting bracket 100 and the first hose 510 away from the handle 600 can be bent, thereby allowing the mounting bracket 100 to move smoothly along the length direction of the suction tube 200. At the same time, when the mounting bracket 100 rotates on the suction tube 200, the position corresponding to the second hose 520 at the end of the mounting bracket 100 and the first hose 510 away from the handle 600 can rotate with the axial rotation of the mounting bracket 100 relative to the suction tube 200 without the first hose 510 rotating, thereby allowing the mounting bracket 100 to rotate smoothly on the suction tube 200.

[0056] In some possible embodiments, when the mounting portion 120 is further provided with a second mounting through hole 122, the hose assembly 500 also includes a third hose 530, the outer wall of the third hose 530 is connected to the outer wall of the second hose 520, and the axial direction of the portion of the third hose 530 connected to the second hose 520 is the same as the axial direction of the second hose 520; the first end of the third hose 530 extends to the handle 600 on the suction device and is connected to the liquid supply module; after the connecting portion 110 is installed on the suction tube 200, the second end of the third hose 530 is connected to the flushing nozzle 300 installed in the second mounting through hole 122; the third hose 530 is used to deliver the cleaning liquid flowing out of the liquid supply module to the flushing nozzle 300.

[0057] It should be noted that the liquid supply module is an external device of the suction device. That is, after the first end of the third hose 530 extends to the handle 600 on the suction device, the first end of the third hose 530 can pass through the handle 600 and connect to the liquid supply module.

[0058] Here, the handle 600 is equipped with a first button for controlling the on / off state of the third hose 530.

[0059] In this embodiment, a third hose 530 is provided on the hose assembly 500 and connected to the outer wall of the second hose 520. The first end of the third hose 530 extends to the handle 600 on the suction device and is connected to the liquid supply module. After the connecting part 110 is installed on the suction tube 200, the second end of the third hose 530 is connected to the rinsing nozzle 300 installed in the second mounting through hole 122. This allows the third hose 530 to transport the cleaning liquid flowing out of the liquid supply module to the rinsing nozzle 300, so that the cleaning liquid can be sprayed from the rinsing nozzle 300 to clean the surface of the camera.

[0060] In some possible implementations, see [link to relevant documentation]. Figure 6 The second end of the second hose 520 is correspondingly disposed to the end of the first hose 510 near the suction port of the suction tube 200; at least a portion of the outer wall of the third hose 530 is connected to the outer wall of the first hose 510, and the axial direction of the portion of the third hose 530 connected to the first hose 510 is the same as the axial direction of the first hose 510.

[0061] Here, the second end of the second hose 520 can be configured to correspond to the second end of the third hose 530.

[0062] In this embodiment, by correspondingly setting the second end of the second hose 520 with the end of the first hose 510 near the suction port of the suction tube 200, when the connecting part 110 is installed on the suction tube 200, the connecting part 110 can directly fix the ends of the first hose 510 and the second hose 520 near the suction port of the suction tube 200 between the mounting bracket 100 and the suction tube 200 by clamping.

[0063] In some possible embodiments, when a third mounting through hole 123 is also provided on the mounting part 120, the hose assembly 500 further includes a fourth hose 540, the outer wall of the fourth hose 540 is connected to the outer wall of the second hose 520, and the axial direction of the portion of the fourth hose 540 connected to the first hose 510 is the same as the axial direction of the first hose 510; the first end of the fourth hose 540 extends to the handle 600 on the suction device and is detachably connected to the air supply module or the flushing system, and the second end of the fourth hose 540 is detachably connected to the third mounting through hole 123 or the air nozzle 400 installed in the third mounting through hole 123.

[0064] After the connecting part 110 is installed on the suction tube 200, and the first end of the fourth hose 540 is detachably connected to the irrigation system and the second end of the fourth hose 540 is detachably connected to the third mounting through hole 123, the fourth hose 540 is used to deliver the irrigation fluid provided by the irrigation system to the third mounting through hole 123 so that the third mounting through hole 123 sprays the irrigation fluid in the irrigation system onto the surgical surface.

[0065] After the connecting part 110 is installed on the suction tube 200, and the first end of the fourth hose 540 is detachably connected to the air supply module, and the second end of the fourth hose 540 is detachably connected to the air blowing nozzle 400 installed in the third mounting through hole 123, the fourth hose 540 is used to deliver the air supply module to the air blowing nozzle 400.

[0066] Here, the handle 600 is provided with a second button for controlling the on / off state of the fourth hose 540.

[0067] In this embodiment, a fourth hose 540 is provided on the hose assembly 500 and connected to the outer wall of the second hose 520. The first end of the fourth hose 540 extends to the handle 600 on the suction device and is connected to the air supply module. After the connecting part 110 is installed on the suction tube 200, the second end of the fourth hose 540 is connected to the blowing nozzle 400 installed in the third mounting through hole 123. This allows the fourth hose 540 to deliver gas from the air supply module to the blowing nozzle 400, so that gas can be blown out from the blowing nozzle 400 to clean the surface of the camera.

[0068] Furthermore, when the air nozzle 400 is not installed in the third mounting through hole 123, the first end of the fourth hose 540 can also be connected to the irrigation fluid system so that the third mounting through hole 123 sprays the irrigation fluid in the irrigation fluid system onto the surgical surface.

[0069] In some possible embodiments, the suction tube 200 is made of a bendable metal tube.

[0070] Here, by selecting a bendable metal tube to manufacture the suction tube 200, it is possible to achieve this by bending the suction tube 200, see [link to relevant documentation]. Figure 12 This allows for adjustment of the suction angle of the suction tube 200, as well as the shooting angle of the camera mounted on the suction tube 200 via the mounting bracket 100.
