Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a medical suction device. Background Technology

[0002] Currently, during surgical procedures, surgeons often use a negative pressure suction device connected to a suction tube to remove blood, irrigation fluid, or exudate to ensure a clear surgical field. Existing suction devices lack a light source, and surgical lights are typically used for illumination. However, blind spots still exist, especially in deep tissues. This significantly hinders the smooth progress of surgery. To address this issue, many surgeons choose to use headlamps for supplemental lighting. However, headlamps also present various problems. For example, wearing a headlamp can cause excessive sweating on the surgeon's head, affecting the procedure; furthermore, because headlamps cannot be used in a sterile environment, surgeons need to tilt their heads or have someone else adjust the light direction.

[0003] The announcement number is CN219743496U, which discloses an integrated optoelectronic medical suction head. The suction head adopts a multi-group composite structure design and can provide lighting assistance during surgical suction. It uses point-emitting optical fiber for front-end lighting of the suction head. However, the suction head uses several light-emitting conductors for direct lighting, which results in a small lighting range in actual use and cannot achieve concentrated lighting, making the lighting effect unsatisfactory in actual use.

[0004] Based on this, a medical suction device is now provided that can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] In one embodiment, such as Figures 1-9As shown, a medical suction device includes a suction tube 11 and an operating handle 26. One end of the suction tube 11 is connected to one end of an adapter 13, and the other end of the adapter 13 is connected to one end of a guide tube 12. The other end of the guide tube 12 is fitted with a second connector 28, which is connected to one end of a connecting hose 29. The adapter 13 is slidably disposed inside a connecting outer tube 16. One end of the connecting outer tube 16 is fitted with an operating handle 26, and one end of the operating handle 26 is fixedly connected to the connecting outer tube 16 via a first connector 25. The first connector 25 is fixedly disposed at one end of the operating handle 26. The other end of the connecting outer tube 16 has an illumination groove containing a plurality of light-emitting LED beads 17 arranged in a circular array. A conductive component for illuminating the plurality of light-emitting LED beads 17 is provided on the outside of the operating handle 26. A light cup 19 is fixedly disposed within the illumination groove. The connecting outer tube 16... A light-transmitting lens 20 is provided at one end corresponding to the position of the lighting slot. Both ends of the adapter 13 are provided with anti-detachment mechanisms to prevent the suction tube 11 and guide tube 12 from detaching. The operating handle 26 is provided with an adjustment mechanism for adjusting the exposed length of the suction tube 11. The anti-detachment mechanism makes it easy to fix both ends of the adapter 13 to one end of the suction tube 11 and one end of the guide tube 12 respectively, preventing the suction tube 11 and guide tube 12 from detaching from the adapter 13 when the adapter 13 slides inside the connecting outer tube 16, causing the liquid drawn by the suction tube 11 to leak into the connecting outer tube 16. The detachable setting between the suction tube 11 and the adapter 13 in the adjustment mechanism makes it easy to adjust the length of the working end of the suction tube 11 according to the different parts to be treated. Since the suction tube 11 and the adapter 13 are detachably connected, long, medium and short different types of suction tubes can also be replaced according to the different diseased parts of the patient, which is flexible, convenient and has good applicability.

[0030] The conductive component includes a first conductive ring 22. Each input terminal of the LED bead 17 is electrically connected to a wire 18, which is disposed within a mounting groove inside the connecting outer tube 16. The other end of each wire 18 is electrically connected to the first conductive ring 22. The first conductive ring 22 is fixedly disposed within an annular groove on one side of a first mounting ring 21, which is fixedly disposed at one end of the connecting outer tube 16. A second conductive ring 24 is tightly fitted to one side of the first conductive ring 22, and is fixedly disposed on one side of a second mounting ring 23. One end of the second mounting ring 23... The first mounting ring 21 is slidably disposed in an annular groove on one side. The second mounting ring 23 is fixedly disposed at one end of the operating handle 26. The second conductive ring 24 is electrically connected to the switch controller 27. The switch controller 27 has a power interface on one side, and the switch controller 27 is electrically connected to an external power supply component through the power interface. In use, when it is necessary to use the suction device to aspirate liquid, one end of the suction tube 11 and the guide tube 12 are respectively sleeved on both ends of the adapter 13. The connection between the suction tube 11 and the guide tube 12 and the adapter 13 is pre-tightened to prevent easy detachment. Then... The adapter 13 is placed inside the connecting outer tube 16. One end of the suction tube 11 extends to the outside of the connecting outer tube 16. Then, the operating handle 26 passes through one end of the guide tube 12 and is fixedly connected to the connecting outer tube 16 via the first connector 25. The first connector 25 here uses an existing component and can be selected according to actual use. This application adopts a threaded connection method, with the external thread of one end of the first connector 25 engaging with the internal thread of one end of the connecting outer tube 16, so that the second conductive ring 24 is tightly attached to the first conductive ring 22. The connecting hose 29 is connected to one end of the guide tube 12 via the second connector 28. The connecting hose 29 is connected to the input end of the external suction device. When in use, the output end of the external power supply component is connected to the power interface on the switch controller 27. Then, the operator holds the operating handle 26 and presses the switch controller 27 to power on the light-emitting beads 17. At the same time, the light cup 19 can concentrate the light emitted by several light-emitting beads 17, and the light emitted through one end of the connecting tube 16 is diffused in a cone shape. It is worth noting that the light-emitting beads 17 in this application can be LED beads or other types of beads, which can be selected according to the actual use.

[0031] The anti-detachment mechanism includes a stop plate 14. The adapter 13 has symmetrical stop plates 14 at both ends. An elastic connecting plate is fixed to one side of each stop plate 14, and the elastic connecting plates are all fixed to the adapter 13. The inner side of the stop plate 14 is arc-shaped and has anti-slip stripes. Roller balls 15 are provided on the outer side of each stop plate 14. One end of the connecting outer tube 16 is rounded. In use, when the adapter 13 needs to be placed inside the connecting outer tube 16, the elastic connecting plate stops the connection. Plate 14 is tilted up so that the inner side of the stop plate 14 is not connected to one end of the suction tube 11 and the guide tube 12. When placing the adapter 13, the operator presses the stop plate 14 so that the stop plate 14 is in close contact with the suction tube 11 and the guide tube 12. Then the adapter 13 is placed inside the connecting outer tube 16, while the ball bearing 15 is in close contact with the inner side of the connecting outer tube 16. Under the action of the ball bearing 15, the stop plate 14 is always in close contact with one end of the suction tube 11 and the guide tube 12, thereby fixing the suction tube 11 and the guide tube 12.

[0032] The adjustment mechanism includes a stop frame 32 and an adjusting wheel 33. The operating handle 26 has an adjustment groove, and the stop frame 32 slides within the adjustment groove. One end of the stop frame 32 has an anti-slip layer on its inner side, and the other end of the stop frame 32 has an adjusting wheel 33 that rotates on its inner side. The adjusting wheel 33 has an anti-slip layer on its outer side. The guide tube 12 has annular stripes on its outer side. The bottom end of the stop frame 32 has symmetrically arranged mounting tubes. A return spring 34 is provided between one end of the mounting tube and the bottom end of the adjustment groove. In use, when the operating handle 26 needs to be installed, since one end of the guide tube 12 needs to be fitted inside the operating handle 26, the user needs to press down the adjusting wheel 33 so that neither the adjusting wheel 33 nor one end of the stop frame 32 is... When the guide tube 12 is installed, the adjusting wheel 33 is released. Under the action of the return spring 34, the stop bracket 32 ​​is pressed tightly against the outside of the guide tube 12, thus fixing the guide tube 12 and preventing the adapter 13 from sliding inside the connecting outer tube 16 during use. When it is necessary to adjust the exposed length of the working end of the suction tube 11, the user presses the adjusting wheel 33, so that one end of the stop bracket 32 ​​is disengaged from the guide tube 12, and the adjusting wheel 33 is pressed tightly against the outside of the guide tube 12. Then the user rotates the adjusting wheel 33, and the adjusting wheel 33 rubs tightly against the outside of the guide tube 12, so that the guide tube 12 drives the adapter 13 to slide inside the connecting outer tube 16, thereby adjusting the exposed length of the working end of the suction tube 11.

[0033] An elliptical hole 35 is provided inside the operating handle 26 near one end of the adjusting wheel 33, and a cylindrical hole 36 is provided inside the other end of the operating handle 26. The minor axis of the elliptical hole 35 is equal to the diameter of the guide tube 12, and the cross-sectional diameter of the cylindrical hole 36 is larger than the cross-sectional diameter of the second connector 28. In use, the elliptical hole 35 facilitates the support of the guide tube 12.

[0034] One end of the connecting outer tube 16 is fitted with a sealing element 30, which is slidably disposed on the suction tube 11. The sealing element 30 has an installation groove in the middle, and a rubber sealing ring 31 is disposed in the installation groove. The rubber sealing ring 31 is tightly disposed with the suction tube 11. In use, by setting the sealing element 30, liquid is prevented from entering the interior of the connecting outer tube 16. At the same time, by setting the rubber sealing ring 31, when one end of the suction tube 11 is moved, liquid adhering to the working end of the suction tube 11 can be scraped off.

[0035] The suction tube 11 and guide tube 12 are made of rigid material, while the connecting hose 29 is made of flexible material. In use, the rigid material of the suction tube 11 and guide tube 12 facilitates the suction tube 11 to attract liquid, the rigid material of the guide tube 12 facilitates the adjustment of the working length of the suction tube 11 by the adjusting wheel 33, and the flexible material of the connecting hose 29 facilitates connection to the input end of the external suction device body.

[0036] The guide tube 12 has a through hole 37 on its side wall, which allows for flexible adjustment of the negative pressure during operation.

[0037] The above embodiment discloses a medical aspirator. When aspiration is required, one end of the aspiration tube 11 and the guide tube 12 are respectively fitted onto both ends of the adapter 13. Pre-tightening force is provided at the connection points of the aspiration tube 11, the guide tube 12, and the adapter 13. The operator presses the stop plate 14, ensuring it is tightly pressed against the aspiration tube 11 and the guide tube 12. Then, the adapter 13 is placed inside the connecting outer tube 16, with the ball bearing 15 tightly pressed against the inner side of the connecting outer tube 16. Under the action of the ball bearing 15, the stop plate 14 remains firmly in contact with the aspiration tube 11 and the guide tube 12. The ends are tightly pressed together to fix the suction tube 11 and the guide tube 12. One end of the suction tube 11 extends to the outside of the connecting outer tube 16. Then, the operating handle 26 passes through one end of the guide tube 12. The user presses down the adjusting wheel 33 so that neither the adjusting wheel 33 nor one end of the stop bracket 32 ​​contacts the outside of the guide tube 12. It is then fixedly connected to the connecting outer tube 16 through the first connector 25. The external thread of one end of the first connector 25 is engaged with the internal thread of one end of the connecting outer tube 16, so that the second conductive ring 24 is tightly pressed against the first conductive ring 22. The connecting hose 29 is connected to one end of the guide tube 12 through the second connector 28. The connection is established, and the connecting hose 29 is connected to the input end of the external suction device body. Then, the sealing element 30 is installed at one end of the connecting outer tube 16 to seal that end. After the guide tube 12 is installed, the adjusting wheel 33 is released, and under the action of the return spring 34, the stop bracket 32 ​​is pressed tightly against the outside of the guide tube 12, thus fixing the guide tube 12. During use, the output end of the external power supply component is connected to the power interface on the switch controller 27. Then, the operator holds the operating handle 26 and presses the switch controller 27 to energize the LED bead 17. When lit, the light cup 19 can concentrate the light emitted by several light-emitting beads 17, and the light emitted through one end of the connecting outer tube 16 is diffused in a cone shape. When it is necessary to adjust the exposed length of the working end of the suction tube 11, the user presses the adjusting wheel 33, so that one end of the stop bracket 32 ​​is disengaged from the guide tube 12, and the adjusting wheel 33 is in close contact with the outside of the guide tube 12. Then the user rotates the adjusting wheel 33, and the adjusting wheel 33 rubs against the outside of the guide tube 12, so that the guide tube 12 drives the adapter 13 to slide inside the connecting outer tube 16, thereby adjusting the exposed length of the working end of the suction tube 11.
