Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, specifically to a post-thyroid surgery compression device. Background Technology

[0002] The incidence of thyroid diseases is increasing year by year, and thyroid tumors and some large thyroid nodules often require surgical treatment. There are many methods and approaches for surgical treatment of thyroid diseases, which can be broadly classified into open surgery and minimally invasive surgery. With the advancement of technology and the increasing demands of patients, more and more thyroid surgeries are choosing minimally invasive surgical methods. Currently, minimally invasive surgical methods for thyroidectomy mainly include thyroidectomy via a subcutaneous tunnel approach through a small incision in the areola and chest wall (mammothoracic approach), thyroidectomy via a small incision in the axilla and a free flap tunnel approach (axillary-thoracic approach), and thyroidectomy via a free flap approach through an incision in the oral mucosa (natural cavity approach). The first two types of surgery are performed on a larger scale and are the mainstream surgical procedures. Both of these surgical methods involve the establishment of a subcutaneous tunnel in the chest wall, which involves the separation of the skin from the deep tissues of the chest wall. If postoperative management is not done properly, it can cause subcutaneous bleeding or effusion, and even the bleeding or effusion can spread to the thyroid bed in the neck, causing a neck hematoma that compresses the trachea, causing respiratory distress or even suffocation. Local effusion is prone to causing local inflammatory reactions or even infection, and delayed wound healing or chronic inflammatory reactions can affect the patient's quality of life. Therefore, accurate and reliable compression hemostasis after surgery is an important preventive measure.

[0003] Currently, when patients undergo thyroidectomy via a small incision in the areola and chest wall, incisions are made in both areolas. During the surgery, three subcutaneous tunnels are created in the chest area for thyroid surgery. Two of these tunnels are adjacent to each other, while the third is located separately. After the surgery, medical staff usually have the patient wear an undershirt to apply pressure with a saline bag over the three subcutaneous tunnels. However, the undershirt cannot effectively secure the saline bag, causing it to shift and resulting in insufficient pressure. Furthermore, due to the non-planar structure of the chest, the pressure applied by the saline bag to the subcutaneous tunnels is not easily adjusted. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a post-thyroidectomy compression device that solves the problem that worn underwear cannot effectively fix the saline bag, causing the saline bag to easily shift and thus failing to achieve the compression effect; moreover, due to the non-planar structure of the chest, the compression force of the saline bag on the tunnel is not easy to adjust.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] A post-thyroidectomy compression device, comprising:

[0007] The garment includes a main belt, with two first support belts fixedly connected to the top two sides of the main belt, and two second support belts fixedly connected to the bottom two sides of the main belt.

[0008] An auxiliary board, vertically mounted on the patient's back, with the ends of two first straps furthest from the main strap wrapping around the patient's neck to the back and then securing them to the top of the auxiliary board; and the ends of two first straps furthest from the main strap wrapping around the patient's abdomen to the back and then securing them to the bottom of the auxiliary board.

[0009] The compression mechanism includes a double-track compression plate, a single-track compression plate, and an adjusting component. The double-track and single-track compression plates are made of elastic material and are both located on the side of the main belt facing the skin. The adjusting component can adjust the compression force of the double-track and single-track compression plates on the subcutaneous tunnel.

[0010] The aforementioned post-thyroidectomy compression device, through the cooperation of the garment and auxiliary plate, positions the double-channel compression plate and the single-channel compression plate at the corresponding positions of the double and single subcutaneous tunnels, making it difficult for the double-channel and single-channel compression plates to move. The compression force of the double-channel and single-channel compression plates on the subcutaneous tunnels can be adjusted by the adjustment component, thereby achieving a better compression effect on the subcutaneous tunnels.

[0011] Furthermore, each of the two first support belts has multiple first locking holes along its length at its ends away from the main belt. The top of the auxiliary plate is provided with a first locking knob, which passes through the corresponding first locking holes on the two first support belts and is threaded into the auxiliary plate. Each of the two second support belts has multiple second locking holes along its length at its ends away from the main belt. The bottom of the auxiliary plate is provided with a second locking knob, which passes through the corresponding second locking holes on the two second support belts and is threaded into the auxiliary plate.

[0012] Furthermore, the bottom surface of the double-pressure plate is provided with a first receiving groove, a wide plate is slidably provided in the first receiving groove, and two parallel first pressure strips are fixedly provided on the bottom surface of the wide plate, and the bottom of both first pressure strips extends to the outside of the first receiving groove. The bottom surface of the single-pressure plate is provided with a second receiving groove, a second pressure strip is slidably provided in the second receiving groove, and the bottom of the second pressure strip extends to the outside of the second receiving groove.

[0013] A first through groove is provided on the main belt at the position corresponding to the double-pressure plate, and a second through groove is provided on the main belt at the position corresponding to the single-pressure plate. A first adjusting rod is slidably provided in the first groove, and the bottom of the first adjusting rod passes through the double-pressure plate and is fixedly connected to the wide plate. A second adjusting rod is slidably provided in the second groove, and the bottom of the second adjusting rod passes through the single-pressure plate and is fixedly connected to the second pressure bar.

[0014] Furthermore, adjustment components are provided on the side of the main belt away from the skin, corresponding to the positions of the double-pressure plate and the single-pressure plate. The adjustment components include adjustment plates, multiple adjustment knobs, and multiple adjustment springs. Adjustment plates are provided at intervals on the side of the main belt away from the skin, corresponding to the positions of the double-pressure plate and the single-pressure plate. Multiple evenly distributed adjustment springs are fixed between the double-pressure plate and one of the adjustment plates. Multiple evenly distributed adjustment springs are fixed between the single-pressure plate and the other adjustment plate. An adjustment knob is fitted inside each adjustment spring. The tops of the multiple adjustment knobs are threaded through the corresponding adjustment plate and extend to the outside. The bottoms of the multiple adjustment knobs slide through the main belt and are rotatably connected to the double-pressure plate and the single-pressure plate, respectively.

[0015] Furthermore, the adjusting plate above the double-pressure plate has a first through groove, and the top of the first adjusting rod passes through the first through groove and is slidably connected. The adjusting plate above the single-pressure plate has a second through groove, and the top of the second adjusting rod passes through the second through groove and is slidably connected.

[0016] Furthermore, a tightening component is connected between the main strap and the auxiliary plate. The tightening component includes a tightening band, a tightening knob, a sliding frame, and two tightening cords. The middle part of the tightening band is fixedly connected to the side of the main strap away from the skin. The two ends of the tightening band extend to the back of the patient and are fixedly connected to the tightening cords. The sliding frame can be slidably fitted onto the auxiliary plate. One end of the tightening knob rotates through the sliding frame and can be snapped onto the auxiliary plate. The other end of the tightening knob has two through collection holes. The ends of the two tightening cords pass through the two collection holes and are both wrapped around the outside of the tightening knob.

[0017] Furthermore, the side of the auxiliary plate has multiple locking holes along the vertical direction, and the inner wall of each locking hole has multiple evenly distributed locking slots. Multiple evenly distributed locking blocks are fixed on the outer side of one end of the tightening knob. When the end of the tightening knob is inserted into the locking hole, the locking block can be inserted into the corresponding locking slot to lock and connect.

[0018] Furthermore, the tightening component also includes a limiting cylinder, which is rotatably sleeved on the outside of the tightening knob, and there is a gap between the limiting cylinder and the tightening knob. The length of the limiting cylinder is less than the length of the tightening knob. The side of the auxiliary plate has multiple limiting holes in the vertical direction, each limiting hole corresponding to a locking hole. The locking hole is opened on the inner bottom wall of the limiting hole. One end of the limiting cylinder passes through the sliding frame and can be inserted into the corresponding limiting hole for locking connection.

[0019] Furthermore, a limiting ring is fixedly sleeved on the outer side of the end of the limiting cylinder away from the auxiliary plate, and an annular groove is opened on the outer side of the tightening knob in the radial direction. The inner side of the limiting ring is inserted into the annular groove for rotational connection, and the width of the annular groove is greater than the thickness of the limiting ring.

[0020] The beneficial effects of this invention are as follows: This post-thyroidectomy compression device, through the cooperation of the garment and auxiliary plate, positions the double-channel compression plate and the single-channel compression plate at the corresponding positions of the double and single subcutaneous tunnels, making it difficult for the double-channel and single-channel compression plates to move. Adjusting the height of the sliding frame enhances the pressure of the main band on the chest skin and adjusts the direction of the main band's pressure. Rotating the adjustment knob at different positions increases the distance between the adjustment plate and the wide plate, and the distance between the adjustment plate and the second compression strip, allowing the first compression strip to compress the double subcutaneous tunnels and the second compression strip to compress the single subcutaneous tunnel. Furthermore, according to actual needs, different rotations of the adjustment knob at different length positions of the adjustment plate allow the first and second compression strips to achieve better compression effects on the subcutaneous tunnels.

[0036] Please see Figures 1 to 2This invention provides a post-thyroidectomy compression device, comprising a garment 10, an auxiliary plate 20, a compression mechanism 30, and a tightening member 40. The garment 10 includes a main strap 11, with two first support straps 12 fixedly connected to the top two sides of the main strap 11 and two second support straps 13 fixedly connected to the bottom two sides of the main strap 11. The auxiliary plate 20 is vertically mounted on the patient's back. The ends of the two first support straps 12 away from the main strap 11 are respectively wrapped around the patient's neck to the back and locked to the top of the auxiliary plate 20. The ends of the two first support straps 12 away from the main strap 11 are respectively wrapped around the patient's abdomen to the back and locked to the bottom of the auxiliary plate 20. The compression mechanism 30 is mounted on the main strap 11 and is used to compress the subcutaneous tunnel. A tightening member 40 is connected between the main strap 11 and the auxiliary plate 20 to adjust the force direction of the main strap 11 towards the skin, so that the main strap 11 fits the skin better.

[0037] In use, the main strap 11 is worn on the patient's chest. Then, the ends of the two first straps 12 are wrapped around the patient's neck from both sides and locked to the top of the auxiliary plate 20. The ends of the two second straps 13 are wrapped around the patient's abdomen from both sides and locked to the bottom of the auxiliary plate 20. At this point, the garment 10 is fixed to the patient's body, providing stable support for the compression mechanism 30. Then, by adjusting the compression mechanism 30, it is aligned with the three subcutaneous tunnels and applied pressure. Moreover, the main strap 11 can be tightened by the tightening member 40, adjusting the force direction of the main strap 11 towards the skin, so that the compression mechanism 30 has a better compression effect on the subcutaneous tunnels.

[0038] The two first support belts 12, at their ends away from the main belt 11, each have multiple first locking holes 121 along their length. The top of the auxiliary plate 20 has a first locking knob 14, which passes through the corresponding first locking holes 121 on the two first support belts 12 and is threaded into the auxiliary plate 20. The two second support belts 13, at their ends away from the main belt 11, each have multiple second locking holes 131 along their length. The bottom of the auxiliary plate 20 has a second locking knob 15, which passes through the corresponding second locking holes 131 on the two second support belts 13 and is threaded into the auxiliary plate 20.

[0039] After the main strap 11 is worn on the patient's chest, move the ends of the two first support straps 12 to the top of the auxiliary plate 20. At this time, according to the size of the patient's neck, overlap the ends of the two first support straps 12 to an appropriate length. Then tighten the first locking knob 14 to fix the ends of the two first support straps 12 against the top of the auxiliary plate 20. Move the ends of the two second support straps 13 to the bottom of the auxiliary plate 20. At this time, according to the size of the patient's abdomen, overlap the ends of the two second support straps 13 to an appropriate length. Then tighten the second locking knob 15 to fix the ends of the two second support straps 13 against the bottom of the auxiliary plate 20, thereby limiting the upper and lower positions of the main strap 11.

[0040] Please refer to the following: Figure 3 and Figure 4 The compression mechanism 30 includes a double-pressure plate 31, a single-pressure plate 32, and an adjusting member 33. The double-pressure plate 31 is used to compress the two subcutaneous tunnels on one side of the upper chest, and the single-pressure plate 32 is used to compress the single subcutaneous tunnel on the other side of the upper chest. Both the double-pressure plate 31 and the single-pressure plate 32 are made of elastic material and are located on the side of the main belt 11 facing the skin. The adjusting member 33 can adjust the compression force of the double-pressure plate 31 and the single-pressure plate 32 on the subcutaneous tunnels. The fact that both the double-pressure plate 31 and the single-pressure plate 32 are made of elastic material allows them to bend, thus enabling them to better conform to the skin of the chest area.

[0041] Specifically, the bottom surface of the double-pressure plate 31 has a first receiving groove 311, within which a wide plate 34 is slidably arranged. Two parallel first pressure strips 35 are fixedly arranged on the bottom surface of the wide plate 34, with the bottoms of both first pressure strips 35 extending to the outside of the first receiving groove 311, making it easier for the two first pressure strips 35 to compress the double subcutaneous tunnels. The bottom surface of the single-pressure plate 32 has a second receiving groove 321, within which a second pressure strip 36 is slidably arranged. The bottom of the second pressure strip 36 extends to the outside of the second receiving groove 321, making it easier for the two first pressure strips 35 to compress the double subcutaneous tunnels. The second compression bar 36 more easily compresses a single subcutaneous tunnel. A first through groove 111 is formed on the main belt 11 at the position corresponding to the double compression plate 31, and a second through groove 112 is formed on the main belt 11 at the position corresponding to the single compression plate 32. A first adjusting rod 371 slides within the first groove 111, with its bottom penetrating the double compression plate 31 and fixedly connected to the wide plate 34. A second adjusting rod 372 slides within the second groove 112, with its bottom penetrating the single compression plate 32 and fixedly connected to the second compression bar 36. The first groove 111 and the second groove 112 respectively penetrate the double compression plate 31 and the single compression plate 32, allowing the first adjusting rod 371 and the second adjusting rod 372 to slide within their respective grooves, facilitating the movement of the wide plate 34 and the second compression bar 36.

[0042] After the garment 10 is put on the patient, the first adjusting rod 371 is moved, causing the first adjusting rod 371 to move the wide plate 34 within the first receiving groove 311, so that the two first compression strips 35 are aligned with the positions of the two subcutaneous tunnels; the second adjusting rod 372 is moved, causing the second adjusting rod 372 to move the second compression strip 36 within the second receiving groove 321, so that the second compression strip 36 is aligned with the position of the single subcutaneous tunnel, thereby improving the accuracy of compression.

[0043] Preferredly, the main strap 11 is provided with adjusting members 33 on the side away from the skin and at the positions corresponding to the double-pressure plate 31 and the single-pressure plate 32. The adjusting members 33 include adjusting plates 333, multiple adjusting knobs 331, and multiple adjusting springs 332. Adjusting plates 333 are provided at intervals on the side of the main strap 11 away from the skin and at the positions corresponding to the double-pressure plate 31 and the single-pressure plate 32. Multiple evenly distributed adjusting springs 332 are fixed between the double-pressure plate 31 and one of the adjusting plates 333. Multiple evenly distributed adjusting springs 332 are fixed between the single-pressure plate 32 and the other adjusting plate 333. Each adjusting spring 332 is fitted with an adjusting knob 331. The top of the multiple adjusting knobs 331 is threaded through the corresponding adjusting plate 333 and extends to the outside. The bottom of the multiple adjusting knobs 331 slides through the main strap 11 and is rotatably connected to the double-pressure plate 31 and the single-pressure plate 32, respectively. Multiple adjusting springs 332 are evenly distributed along the length of the double-track compression plate 31 and the single-track compression plate 32 to apply corresponding compression forces at different length positions on the double-track compression plate 31 and the single-track compression plate 32. The first compression strip 35 and the second compression strip 36 are both made of elastic material, so that the first compression strip 35 and the second compression strip 36 can adapt to the curvature of the chest skin surface.

[0044] When it is necessary to adjust the pressure at different positions along the length of the double-pressure plate 31 and the single-pressure plate 32, for the pressure of the two subcutaneous tunnels, rotate the corresponding adjustment knob 331. Since the adjustment knob 331 is threadedly connected to the adjustment plate 333, the distance between the adjustment plate 333 and the double-pressure plate 31 increases. At this time, the adjustment spring 332 is stretched, so that the double-pressure plate 31 exerts a force on the adjustment plate 333 towards the skin. This causes the adjustment plate 333 to drive the adjustment knob 331 to apply pressure to the skin, thereby causing the adjustment knob 331 to drive the first pressure bar 35 to press the two subcutaneous tunnels. At different length positions of the adjustment plate 333, the number of rotations of the adjustment knob 331 is also different according to actual needs, so as to achieve a better pressure effect. The pressure of the single subcutaneous tunnel is operated in the same way.

[0045] The adjusting plate 333 above the double-pressure plate 31 has a first through slot 334, through which the top of the first adjusting rod 371 passes and is slidably connected. The adjusting plate 333 above the single-pressure plate 32 has a second through slot 335, through which the top of the second adjusting rod 372 passes and is slidably connected. The first through slot 334 and the second through slot 335 are provided to facilitate the movement of the first adjusting rod 371 and the second adjusting rod 372.

[0046] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6In this embodiment, a tightening member 40 is connected between the main strap 11 and the auxiliary plate 20. The tightening member 40 includes a tightening band 41, a tightening knob 44, a sliding frame 43, and two tightening ropes 42. The middle part of the tightening band 41 is fixedly connected to the side of the main strap 11 away from the skin. The two ends of the tightening band 41 extend to the back of the patient and are fixedly connected to the tightening ropes 42. The sliding frame 43 can be slidably sleeved on the auxiliary plate 20. One end of the tightening knob 44 rotates through the sliding frame 43 and can be snapped onto the auxiliary plate. The other end of the tightening knob 44 has two through collection holes 441. The ends of the two tightening ropes 42 pass through the two collection holes 441 and are both wrapped around the outside of the tightening knob 44.

[0047] To ensure the main strap 11 fits better against the skin, the sliding frame 43 is moved up and down on the auxiliary plate 20 to adjust the direction of the tension of the two tightening ropes 42 on the main strap 11, thereby adjusting the direction of the pressure of the main strap 11 on the chest skin; then the tightening knob 44 is rotated so that the length of the two tightening ropes 42 is continuously wrapped around the tightening knob 44, so that the tightening ropes 42 tighten the sides of the main strap 11, increasing the pressure of the main strap 11 on the chest.

[0048] Preferably, the side of the auxiliary plate 20 has multiple locking holes 21 vertically arranged on its side. Each locking hole 21 has multiple evenly distributed locking slots 22 on its inner sidewall. Multiple evenly distributed locking blocks 45 are fixed to the outer side of one end of the tightening knob 44. When the end of the tightening knob 44 is inserted into the locking hole 21, the locking block 45 can be inserted into the corresponding locking slot 22 to engage and connect. In the initial state, the end of the tightening knob 44 is engaged in the locking slot 22, and the tightening knob 44 is limited and cannot rotate.

[0049] When it is necessary to adjust the tightening force of the tightening rope 42 on the main belt 11, pull the tightening knob 44 outward to disengage the locking block 45 from the slot 22. Then rotate the tightening knob 44 so that the lengths of the two tightening ropes 42 continuously wrap around the tightening knob 44. Then push the tightening knob 44 inward so that the locking block 45 can be inserted into the corresponding slot 22, thereby limiting the tightening knob 44 to prevent it from rotating, ensuring the stability of the tightening rope 42 when tightening the main belt 11.

[0050] Preferably, the tightening component 40 also includes a limiting cylinder 46, which is rotatably sleeved on the outside of the tightening knob 44, with a gap between the limiting cylinder 46 and the tightening knob 44. The length of the limiting cylinder 46 is less than the length of the tightening knob 44. Multiple limiting holes 23 are vertically formed on the side of the auxiliary plate 20, each corresponding to a locking hole 21. The locking hole 21 is located on the inner bottom wall of the limiting hole 23. One end of the limiting cylinder 46 passes through the sliding frame 43 and can be inserted into the corresponding limiting hole 23 for locking connection. When the sliding frame 43 moves to a suitable high position on the auxiliary plate 20, the end of the limiting cylinder 46 is slidably inserted into the corresponding limiting hole 23, at which point the sliding frame 43 is fixed and cannot move.

[0051] Furthermore, a limiting ring 47 is fixedly sleeved on the outer side of the end of the limiting cylinder 46 away from the auxiliary plate 20. An annular groove 442 is formed on the outer side of the tightening knob 44 in the radial direction. The inner side of the limiting ring 47 is inserted into the annular groove 442 for rotatable connection, and the width of the annular groove 442 is greater than the thickness of the limiting ring 47. The limiting rotational cooperation between the limiting ring 47 and the annular groove 442 prevents the tightening knob 44 from sliding outward too far, thus preventing the tightening knob 44 from being pulled out of the sliding frame 43 as a whole. At the same time, the limiting ring 47 and the limiting cylinder 46 limit the outer circumference of the tightening knob 44 to prevent the tightening knob 44 from wobbling left and right. Moreover, when it is necessary to slide the locking block 45 out of the locking slot 22, the limiting ring 47 can slide within the annular groove 442.

[0052] The working principle of this invention is as follows: In use, the main strap 11 is worn on the patient's chest, so that the double-channel compression plate 31 and the single-channel compression plate 32 correspond to the positions of the double subcutaneous tunnel and the single subcutaneous tunnel, respectively. The ends of the two first support straps 12 are moved to the top position of the auxiliary plate 20, and the ends of the two first support straps 12 are secured to the top of the auxiliary plate 20 by tightening the first locking knob 14. The ends of the two second support straps 13 are moved to the bottom position of the auxiliary plate 20, and the ends of the second support straps 13 are secured to the bottom position by tightening the second locking knob 14. Locking knob 15 secures the ends of the two second straps 13 against the bottom of the auxiliary plate 20, thereby limiting the upper and lower positions of the main strap 11; then, according to the curvature of the patient's chest skin surface, the sliding frame 43 is moved to a suitable height and fixed by the limiting cylinder 46; rotating the tightening knob 44 causes the two tightening ropes 42 to continuously wrap around the tightening knob 44, thereby adjusting the pressure and direction of the main strap 11 on the chest skin, and locking the tightening knob 44 in place;

[0053] Then, the first adjusting rod 371 and the second adjusting rod 372 are moved so that the two first compression strips 35 are aligned with the positions of the double subcutaneous tunnels and the second compression strip 36 is aligned with the position of the single subcutaneous tunnel. Then, the adjusting knobs 331 at different positions on the adjusting plate 333 are adjusted. By rotating the adjusting knobs 331 at the corresponding positions, the distance between the adjusting plate 333 and the wide plate 34 (the second compression strip 36) is increased. At this time, the adjusting spring 332 is stretched, so that the double compression plate 31 exerts a force on the adjusting plate 333 towards the skin. This causes the adjusting plate 333 to drive the adjusting knob 331 to apply pressure to the skin. Finally, the adjusting knob 331 drives the first compression strip 35 to compress the double subcutaneous tunnels and the second compression strip 36 to compress the single subcutaneous tunnel.

[0054] The beneficial effects of this invention are as follows: This post-thyroidectomy compression device, through the cooperation of the garment 10 and the auxiliary plate 20, positions the double-channel compression plate 31 and the single-channel compression plate 32 at the corresponding positions of the double and single subcutaneous tunnels, making it difficult for the double-channel compression plate 31 and the single-channel compression plate 32 to move. Adjusting the height of the sliding frame 43 enhances the compression force of the main strap 11 on the chest skin and adjusts the direction of the compression force. Rotating the adjustment knob 331 at different positions increases the distance between the adjustment plate 333 and the wide plate 34, and also increases the distance between the adjustment plate 333 and the second compression strip 36, allowing the first compression strip 35 to compress the double subcutaneous tunnels and the second compression strip 36 to compress the single subcutaneous tunnel. Furthermore, according to actual needs, different rotations of the adjustment knob 331 at different length positions of the adjustment plate 333 allow the first compression strip 35 and the second compression strip 36 to achieve better compression of the subcutaneous tunnels.
