Description

Technical Field

[0001] This invention relates to the field of neck drainage technology, and more specifically, to a neck drainage device for otolaryngology head and neck surgery. Background Technology

[0002] Compared to drainage of other parts of the body, otolaryngological drainage has a higher operational risk factor. At the same time, the drainage fluid is mostly a highly viscous liquid, which can easily cause blockage inside the drainage tube when it flows through it. This is especially true in places where the drainage tube has a large curvature or bends, where blockage or even clumping can occur, thus increasing the difficulty of otolaryngological drainage.

[0003] However, most existing ENT drainage devices lack the function of clearing the inside of the drainage tube. At the same time, when clearing the inside of the drainage tube, there is no consideration for safety issues such as backflow in the drainage tube, which increases the risk factor when using the device and thus reduces the drainage effect of the device. Summary of the Invention

[0004] This invention provides a neck drainage device for otolaryngology head and neck surgery to solve the problems that most existing otolaryngology drainage devices lack the function of clearing the inside of the drainage tube, and at the same time, they do not consider the safety issues such as backflow in the drainage tube when clearing the inside of the drainage tube, which increases the risk factor when using the device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A neck drainage device for otolaryngology head and neck surgery includes a first fixation ring. The top of the first fixation ring is provided with multiple sets of fixing components. Each fixing component includes multiple arc-shaped frames and movable frames fixedly connected to the top of the first fixation ring. The arc-shaped frames and the movable frames are arranged in pairs along the top of the first fixation ring, and the arc-shaped frames and the movable frames are slidably arranged along the top of the first fixation ring.

[0007] Preferably, the arc-shaped frame is made of memory material, and soft clips are provided on the inner side of the arc-shaped frame, with the soft clips evenly arranged along the inner side of the arc-shaped frame.

[0008] Preferably, the movable frame has multiple fixed frames, and an adjustment component is provided inside the fixed frame. One end of the fixed frame has a pair of through holes pointing towards the inside of the soft card. A pair of clips are provided outside the through holes, and the two clips are arranged opposite to each other.

[0009] Preferably, the adjustment assembly includes a rotating seat rotatably engaged inside the fixed frame, a telescopic pad connected to the outside of the rotating seat, a connecting seat connected to the output end of the telescopic pad, and a guide wheel rotatably engaged inside the connecting seat.

[0010] Preferably, a dredging component is provided on the outside of the connecting seat. The dredging component includes a pair of rotating shafts rotatably connected to the outside of the connecting seat via a fixing ring. The two rotating shafts are connected by a collar. A pair of squeezing blocks are rotatably connected to the collar via a torsion spring. A control frame is eccentrically sleeved on the outside of the rotating shafts. The control frame is connected to the fixing ring via a control rod.

[0011] Preferably, the first retaining ring opening is connected to a second retaining ring via an adjusting assembly. The adjusting assembly includes a first connecting arm rotatably connected to both ends of the first retaining ring opening, a second connecting arm hinged to one end of the first connecting arm, and the free end of the second connecting arm rotatably connected to a fixed shaft provided at both ends of the second retaining ring opening.

[0012] Preferably, the second retaining ring has multiple side grooves on its outer side, a screw is fixedly installed on the outer side of the second retaining ring, a knob is screwed onto the outer side of the screw, and a retaining groove is provided on the outer side of the first retaining ring, with the knob rotating and engaging in the retaining groove.

[0013] Preferably, a guide ring is provided on the outer side of the first retaining ring, a guide rod is provided inside the guide ring, a limit block is fixedly connected to the top end of the guide rod, the bottom end of the guide rod is connected to the bottom end of the second retaining ring, and the plane of the second retaining ring is perpendicular to the axial direction of the guide rod.

[0014] Preferably, an elastic pad is provided between the two first connecting arms. The elastic pad is hollow, and an opening at one end of the elastic pad communicates with either of the first connecting arms. A control cable is connected to the inner wall of the end of the elastic pad away from the opening, and a pull block is provided at one end of the control cable.

[0015] Preferably, a side plate is provided on the outer side of the first connecting arm near the pull block, and a connecting button is provided at the bottom end of the side plate. A pair of rotating plates are rotatably engaged on the outer side of the connecting button, and both rotating plates are connected to a spacer clamp, which is clamped on the outer side of the control cable.

[0016] The principle and beneficial effects of this technical solution:

[0017] (1) The fixing component provided in this invention can be used in conjunction with the adjusting component to fix the drainage tube in the patient's head and neck, and at the same time adjust the local curvature of the drainage tube to prevent the drainage tube from maintaining the same curvature for a long time or from being blocked at the bend due to local compression. Then, the unblocking component is set on the adjusting component to help the device unblock the blockage in the drainage tube. When using the fixing component, first slide the arc frame and the moving frame along the top of the first fixing ring according to the position of the patient's drainage tube. Insert the drainage tube into the soft card set in the inner side of the arc frame. Then move the moving frame synchronously so that the through hole set by the fixing frame on the moving frame is aligned with the soft card. Insert the free end of the drainage tube into the through hole. After the drainage tube is inserted into one of the through holes in the current corresponding fixing frame, the free end of the drainage tube is pulled out from the inner side of the other through hole at one end of the fixing frame. The drainage tube is softly fixed by the clip set on the outer side of the through hole. Fix the drainage tube along the side groove opened on the outer side of the second fixing ring and then connect it to the drainage bag.

[0018] (2) The distance adjustment component provided in this invention can adjust the distance between the first retention ring and the second retention ring to adapt to the neck length of different patients and fix the neck posture of the patients. When using the distance adjustment component, rotate the knob that is rotated in the retention groove. Since the knob is inserted on the outside of the screw, rotating the knob can move the second retention ring along the screw axis until the distance between the first retention ring and the second retention ring matches the neck length of the patient.

[0019] (3) The elastic pad provided in this invention can adjust the distance between the two first connecting arms and the second connecting arm, thereby changing the opening size of the first retaining ring and the second retaining ring. When it is necessary to reduce the opening, pull the pull block provided at one end of the control cable, and the control cable will pull the elastic pad to shorten, so that the elastic pad can release air. When it is necessary to lock the length of the elastic pad, rotate the two rotating plates along the connecting button, and drive the fixed-distance clamp connected to the two rotating plates to clamp the control cable.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0027] Example:

[0028] like Figures 1 to 5 As shown, the present invention provides a neck drainage device for otolaryngology head and neck surgery, including a first fixation ring 4. The top end of the first fixation ring 4 is provided with multiple sets of fixing components. The fixing components include multiple arc-shaped frames 3 and movable frames 1 fixedly connected to the top end of the first fixation ring 4. The arc-shaped frames 3 and movable frames 1 are arranged in pairs along the top end of the first fixation ring 4, and the arc-shaped frames 3 and movable frames 1 are slidably arranged along the top end of the first fixation ring 4.

[0029] like Figure 1 As shown, the arc-shaped frame 3 is made of memory material, and soft cards 2 are provided on the inner side of the arc-shaped frame 3. The soft cards 2 are evenly arranged along the inner side of the arc-shaped frame 3.

[0030] like Figure 1 and Figure 2 As shown, the movable frame 1 has multiple fixed frames 6, and an adjustment component is provided inside the fixed frame 6. One end of the fixed frame 6 has a pair of through holes 7, which point to the inside of the soft card 2. A pair of clips 8 are provided outside the through holes 7, and the two clips 8 are arranged opposite to each other.

[0031] like Figure 2 and Figure 3 As shown, the adjustment assembly includes a rotating seat 20 that is rotatably mounted inside the fixed frame 6, a telescopic pad 18 connected to the outside of the rotating seat 20, a connecting seat 19 connected to the output end of the telescopic pad 18, and a guide wheel 11 that is rotatably mounted inside the connecting seat 19.

[0032] like Figure 3As shown, a dredging component is provided on the outside of the connecting seat 19. The dredging component includes a pair of rotating shafts 15 rotatably connected to the outside of the connecting seat 19 via a fixing ring 16. The two rotating shafts 15 are connected by a collar 13. A pair of pressing blocks 12 are rotatably connected to the collar 13 via a torsion spring. A control frame 14 is eccentrically sleeved on the outside of the rotating shafts 15. The control frame 14 is connected to the fixing ring 16 via a control rod 17.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, the first retaining ring 4 has an opening end connected to a second retaining ring 5 via an adjusting assembly. The adjusting assembly includes a first connecting arm 25 rotatably connected to both ends of the opening of the first retaining ring 4, and a second connecting arm 28 hinged to one end of the first connecting arm 25. The free end of the second connecting arm 28 is rotatably connected to a fixed shaft 10 provided at both ends of the opening of the second retaining ring 5.

[0034] like Figure 1 and Figure 4 As shown, the second retaining ring 5 has multiple side grooves 24 on its outer side, and a screw 23 is fixedly installed on the outer side of the second retaining ring 5. A knob 22 is screwed onto the outer side of the screw 23. A retaining groove 21 is provided on the outer side of the first retaining ring 4. The knob 22 rotates and is locked in the retaining groove 21.

[0035] like Figure 1 , Figure 2 and Figure 5 As shown, a guide ring 9 is provided on the outer side of the first retaining ring 4, and a guide rod 30 is provided inside the guide ring 9. A limit block 29 is fixedly connected to the top of the guide rod 30, and the bottom end of the guide rod 30 is connected to the bottom end of the second retaining ring 5. The plane of the second retaining ring 5 is perpendicular to the axial direction of the guide rod 30.

[0036] The distance adjustment component can adjust the distance between the first retaining ring 4 and the second retaining ring 5 to adapt to the neck length of different patients and fix the neck posture of the patients. When using the distance adjustment component, rotate the knob 22 that is rotated in the retaining groove 21. Since the knob 22 is inserted on the outside of the screw 23, rotating the knob 22 can move the second retaining ring 5 along the axis of the screw 23 until the distance between the first retaining ring 4 and the second retaining ring 5 matches the neck length of the patient. During the movement of the second retaining ring 5, the guide rod 30 set on the outside of the second retaining ring 5 will slide synchronously along the guide ring 9 set on the outside of the first retaining ring 4. The movement of the screw 23 is limited by the limiting block 29 fixedly connected to the top of the guide rod 30. At the same time, the opening size of the first retaining ring 4 and the second retaining ring 5 is adjusted by the first connecting arm 25 and the second connecting arm 28 so that the device can adapt to the neck contour of different patients.

[0037] like Figure 4 and Figure 5As shown, an elastic pad 26 is provided between the two first connecting arms 25. The elastic pad 26 is hollow. An opening at one end of the elastic pad 26 is connected to either of the first connecting arms 25. A control cable 27 is connected to the inner wall of the end of the elastic pad 26 away from the opening. A pull block 34 is provided at one end of the control cable 27.

[0038] like Figure 4 and Figure 5 As shown, a side plate 32 is provided on the outside of the first connecting arm 25 near the pull block 34. A connecting button 31 is provided at the bottom of the side plate 32. A pair of rotating plates 33 are rotatably locked on the outside of the connecting button 31. Both rotating plates 33 are connected to a spacer clip 35, which is clamped on the outside of the control cable 27.

[0039] The elastic pad 26 can adjust the distance between the two first connecting arms 25 and the second connecting arm 28, thereby changing the opening size of the first retaining ring 4 and the second retaining ring 5. When it is necessary to reduce the opening, pull the pull block 34 at one end of the control cable 27. The control cable 27 will then pull the elastic pad 26 to shorten, allowing the elastic pad 26 to release air. When it is necessary to lock the length of the elastic pad 26, rotate the two rotating plates 33 along the connecting button 31. This will cause the spacer connected to the two rotating plates 33 to clamp the control cable 27. Similarly, when it is necessary to increase the opening, release the spacer and allow the elastic pad 26 to naturally absorb air and reset until the opening increases to a suitable width.

[0040] The specific usage and function of this embodiment are as follows:

[0041] The fixing component in this invention can work with the adjusting component to fix the drainage tube in the patient's head and neck, and simultaneously adjust the local curvature of the drainage tube to prevent it from maintaining the same curvature for a long time or from becoming blocked at the bend due to local compression. A clearing component is also synchronously installed on the adjusting component to help the device clear any blockages in the drainage tube. When using the fixing component, first, according to the position of the patient's drainage tube, slide the arc-shaped frame 3 and the moving frame 1 along the top of the first fixing ring 4. Insert the drainage tube into the soft clip 2 located close to the inside of the arc-shaped frame 3, and then move the moving frame 1 synchronously. Align the through hole 7 on the frame 1 with the soft card 2 through the fixed frame 6, and insert the free end of the drainage tube into the through hole 7. After the drainage tube is inserted into one of the through holes 7 in the current fixed frame 6, the free end of the drainage tube is inserted out from the inside of the other through hole 7 at one end of the fixed frame 6. The drainage tube is softly fixed by the clip 8 set on the outside of the through hole 7. Then, select the path according to the length of the drainage tube. When the drainage tube is long, insert the drainage tube into the through hole 7 of the adjacent fixed frame 6 in the same way and repeat the above path until the remaining length of the drainage tube is short. Then fix the drainage tube along the side groove 24 opened on the outside of the second fixing ring 5 and connect it to the drainage bag.

[0042] When adjusting the curvature or position of the drainage tube bend using the adjustment assembly, the rotating seat 20, which is rotated and locked inside the fixed frame 6, rotates or the telescopic pad 18 connected to the outside of the rotating seat 20 extends or retracts, causing the connecting seat 19 to move. The guide wheel 11, which is rotated and locked inside the connecting seat 19, will then squeeze or release the squeezing of the drainage tube, reducing its curvature. When adjusting the position of the drainage tube bend using the adjustment assembly, the two squeezing blocks 12, which are rotatably connected to the outside of the connecting seat 19 via the collar 13, will move synchronously with the collar 13. The squeezing block 12 will move along the outer wall of the drainage tube, squeezing the drainage tube along the moving path of the collar 13, thereby helping to resolve the internal liquid blockage of the drainage tube. At the same time, a control magnetic block is provided at the connection position between the squeezing block 12 and the collar 13. When the collar 13 is reset, it can drive the squeezing block 12 to move outward to prevent reverse squeezing from causing the drainage fluid to flow back. The control frame 14 eccentrically sleeved on the outside of the rotating shaft 15 can adjust the direction of the squeezing block 12 connected to the rotating shaft 15 through the collar 13, so that the squeezing block 12 can adapt to different drainage tube setting directions.
