Description

Technical Field

[0001] This invention specifically relates to a compression device after thyroid cancer surgery via the axillary approach. Background Technology

[0002] Endoscopic thyroid surgery represents a major advancement in the field of thyroid surgery over the past 20 years. It enables minimally invasive and cosmetically pleasing thyroid incisions, meeting patients' aesthetic needs and reducing their psychological stress. Simultaneously, the magnification and precise surgical techniques employed by the endoscope allow for better identification and protection of important structures such as the recurrent laryngeal nerve, superior laryngeal nerve, and parathyroid glands, reducing surgical complications and improving quality of life. Current main surgical approaches include the thoracomammary approach, axillary approach, transoral approach, and double areolar double axillary approach (BABA), each with its own advantages and disadvantages.

[0003] Endoscopic thyroid surgery is a minimally invasive procedure. The main method involves making three incisions in the right axilla and the outer side of the breast: the middle one is the endoscopic incision, and the two on the sides are the operating incisions. Dissection begins under the skin and continues until the front of the thyroid gland is reached. The superior, middle and inferior arteries and veins supplying the thyroid gland are freed and severed. The thyroid gland is then freed from the trachea and removed through a retrieval bag. The endoscope and instruments are then pushed out, the incision is sutured, and the surgery is completed.

[0004] However, after thyroid cancer surgery via the axillary approach, it is often necessary to apply pressure to the surgical site to aid wound healing and prevent subcutaneous emphysema and hematoma. The current method generally uses a salt bag, which is a certain weight of salt bag that is pressed against the surgical incision. However, clinical findings have shown that when the patient moves during use, the salt bag is prone to displacement, resulting in insufficient pressure. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the technical problem to be solved by this invention is to provide a compression device for thyroid cancer surgery via the axillary approach, which can effectively compress the incision site after thyroid cancer surgery via the axillary approach, thereby reducing the risk of subcutaneous emphysema and subcutaneous hematoma.

[0006] To achieve the above objectives, the present invention provides a compression device for thyroid cancer surgery via an axillary approach, comprising:

[0007] The beneficial effects of this invention are:

[0008] The aforementioned compression device for thyroid cancer surgery via the axillary approach is used by first placing the backboard on the operating table, then having the patient lie supine on the operating table. The four connecting straps are then placed on both sides of the neck and in the two armpits for later use. After the surgery, the compression pad is pressed tightly against the surgical site. The ends of the four connecting straps are then connected to the compression pad, and the tension of the connecting straps is adjusted using the tension adjustment mechanism to ensure the compression pad is firmly pressed against the surgical incision.

[0009] This postoperative compression device uses a connecting strap to fix the compression pad, which prevents the pad from moving due to the patient's movement during the compression process, thus avoiding poor compression effect. In addition, the compression degree can be adjusted by the tension adjustment structure to achieve the best compression effect. Attached Figure Description

[0019] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0020] Please see Figures 1 to 6 The present invention provides a compression device for thyroid cancer surgery via the axillary approach, comprising a compression member 100, a back plate 200, a connecting strap 300, and a tension adjustment structure 400.

[0021] Specifically, the clamping component 100 includes a clamping sheet 110, which is a flexible sheet. The flexible clamping sheet 110 can adapt to the shape of the surgical area. The backplate 200 is placed on the patient's back. There are four connecting straps 300, one end of which is connected to the backplate 200. The four connecting straps 300 can be detachably connected to the edges of the clamping sheet 110, passing around the patient's neck and two armpits. The connection method can be plug-in or hook-on. Of course, in specific implementations, the number of connecting straps 300 can also be other, such as 2, 3, 5, etc.

[0022] Each connecting belt 300 is provided with a tension adjustment structure 400, which can adjust the tension of the connecting belt 300 after it is connected to the pressure plate 110.

[0023] In use, first place the backplate 200 on the operating table, then have the patient lie supine on the operating table. Next, place the four connecting straps 300 on both sides of the neck and in the two armpits for later use. After the surgery, press the pressure plate 110 firmly against the surgical site. Then connect the ends of the four connecting straps 300 to the pressure plate 110. Adjust the tension of the connecting straps 300 using the tension adjustment structure 400 to firmly press the pressure plate 110 onto the surgical incision.

[0024] Using this postoperative compression device, the compression pad 110 is fixed by the connecting strap 300, which can prevent the compression pad 110 from moving due to the patient's movement during the compression process, thus preventing the compression effect from being poor. In addition, the compression degree can be adjusted by the tension adjustment structure 400 to achieve the best compression effect.

[0025] In this embodiment, the connecting strap 300 passes through the tension adjustment structure 400, which can either retract or extend the connecting strap 300.

[0026] When the tension adjustment structure 400 retracts the connecting belt 300, the connecting belt 300 can be tightened; conversely, when the tension adjustment structure 400 releases the connecting belt 300, the connecting belt 300 can be loosened.

[0027] Of course, in other embodiments, the tensioning adjustment structure 400 can also be a lifting mechanism. When the lifting mechanism pushes the connecting belt 300 connected to the pressure plate 110 outward, the connecting belt 300 can be tightened. Conversely, when the height of the lifting mechanism decreases, the connecting belt 300 can be loosened.

[0028] Specifically, the tension adjustment structure 400 includes a mounting shell 410, a winding rod 420, and a rotation drive 430. The left and right side walls of the mounting shell 410 are respectively provided with a first slot 411 and a second slot communicating with their inner cavities. The winding rod 420 is rotatably mounted inside the mounting shell 410 and located between the first slot 411 and the second slot. The end of the winding rod 420 extends out of the mounting shell 410, and a through slot communicating with the left and right sides is provided on the winding rod 420. The connecting strap 300 passes through the first slot 411, through the through slot, and then through the second slot. The rotation drive 430 is mounted on the mounting shell 410 and connected to the winding rod 420, used to drive the winding rod 420 to rotate clockwise or counterclockwise.

[0029] In use, after the connecting strap 300 is connected to the pressure plate 110, the connecting strap 300 is wound around the winding rod 420 by hand-holding the rotating drive 430 to tighten the connecting strap 300; conversely, the connecting strap 300 is loosened by rotating the winding rod 420 in the opposite direction.

[0030] In this embodiment, the rotation drive component 430 includes a ratchet 431, a lever 432, a first pawl 433, a second pawl 434, and a stop plate 435. The ratchet 431 is sleeved and fixed to the end of the winding rod 420, and the ratchet teeth of the ratchet 431 are rectangular. The lever 432 is rotatably mounted on the mounting housing 410. The mounting end of the first pawl 433 is hinged to the middle of the lever 432. The pawl end of the first pawl 433 extends towards one side of the ratchet 431 and engages between the ratchet teeth of the ratchet 431. Rotating the lever 432 to one side can drive the ratchet 431 to rotate in the same direction through the first pawl 433.

[0031] The second pawl 434 is symmetrically arranged with the first pawl 433 opposite to the lever 432. The baffle 435 is fixed to the mounting shell 410 and covers the ratchet teeth between the second pawl 434 and the first pawl 433.

[0032] In use, the user drives the lever 432, which in turn drives the winding rod 420 to rotate via the first pawl 433 and the second pawl 434. Since the ratchet 431 and the pawl are engaged in an intermittent drive, the tension of the connecting belt 300 can be flexibly adjusted during use as needed.

[0033] This structure allows for easy rotation of the winding rod 420 in both directions, facilitating adjustment of the tightness of the two connecting straps 300. Alternatively, in other embodiments, the connecting straps 300 can be manually rotated after the pawl disengages from the ratchet 431, thus adjusting their looseness.

[0034] In a more preferred embodiment, the rotation drive 430 further includes a first elastic element 436 and a second elastic element 437. The first elastic element 436 and the second elastic element 437 are symmetrically arranged with respect to the actuating lever 432. The ends of the first elastic element 436 and the second elastic element 437 that are close to each other are connected to the actuating lever 432, and the ends of the first elastic element 436 and the second elastic element that are far from each other are respectively connected to the mounting housing 410.

[0035] The first elastic element 436 and the second elastic element 437 facilitate the automatic return of the lever 432 to the middle position after each drive, thus facilitating the drive of the first pawl 433 and the second pawl 434.

[0036] In a preferred embodiment, each lever 432 is threaded with a locking screw 438. By rotating the locking screw 438, the end of the locking screw 438 can abut against and be fixed to the outer wall of the mounting housing 410.

[0037] The lever 432 can be fixed by the locking screw 438 to prevent the lever 432 from rotating arbitrarily and affecting the tightness of the connecting belt 300.

[0038] In this embodiment, the clamping member 100 further includes a clamping block 120. There are multiple clamping blocks 120, which are spaced apart on the clamping plate 110, and the clamping blocks 120 can press against the corresponding cuts.

[0039] When installing the pressure plate 110, pressing each pressure block 120 against the corresponding cut can improve the pressing effect.

[0040] Preferably, the pressure of the pressure block 120 pressing against the cut is adjustable. This allows for adjustment of the pressure level as needed.

[0041] Specifically, the pressure block 120 includes a mounting sleeve 121, a pressure plate 122, and a push rod 123. The mounting sleeve 121 is a hollow sleeve with both the top and bottom open, and the pressure plate 122 is located on the side closer to the human body. The push rod 123 is inserted into the mounting sleeve 121 and extends the mounting sleeve 121 to connect with the pressure plate 122. The push rod 123 can drive the pressure plate 122 to move closer to or away from the human body.

[0042] When the clamping level needs to be adjusted, simply drive push rod 123.

[0043] In this embodiment, the push rod 123 includes a connecting plate 1231 and a screw 1232. The pressure plate 122 has a mounting hole on the side away from the human body. The connecting plate 1231 is rotatably disposed within the mounting hole. One end of the screw 1232 rotatably extends into the mounting hole and is rotatably connected to the connecting plate 1231. The screw 1232 also passes through the mounting sleeve 121 and is threadedly connected to the mounting sleeve 121.

[0044] In use, rotating the screw 1232 clockwise will drive the pressure plate 122 to move closer to the human body, while rotating the screw 1232 counterclockwise will drive the pressure plate 122 to move backward.

[0045] The above-mentioned method of using the compression device after thyroid cancer surgery via the axillary approach:

[0046] In use, first place the backplate 200 on the operating table, then have the patient lie supine on the operating table. Next, place the connecting straps 300 on both sides of the neck and in the two armpits for later use. After the surgery, press the pressure plate 110 tightly against the surgical site, aligning each pressure plate 122 with the corresponding incision. Then connect the ends of the four connecting straps 300 to the pressure plate 110. Next, move the lever 432 left and right to wind the connecting straps 300 around the winding rod 420. Then tighten the locking screw 438. Finally, rotate each screw 1232 to adjust the pressure of the pressure plate 122 to the appropriate level.

[0047] When it is necessary to release the clamping, the winding rod 420 can be driven to rotate in the opposite direction to loosen the connecting strip 300. Then, the connecting strip 300 can be separated from the pressure plate 110, and the pressure plate 110 can be removed.

[0048] Using this postoperative compression device, the compression pad 110 is fixed by the connecting strap 300, which can prevent the compression pad 110 from moving due to the patient's movement during the compression process, thus preventing the compression effect from being poor. In addition, the compression degree can be adjusted by the tension adjustment structure 400 to achieve the best compression effect.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
