[0035] Example
[0036] like Figure 1-Figure 10 As shown in the figure, a postoperative auxiliary recovery device for thyroid cancer patients includes a fixing mechanism 100 that is sleeved on the neck; a first limiting mechanism 200 is arranged on the fixing mechanism 100, and the first limiting mechanism 200 includes a first connecting rod 210 and a second connecting rod 220 that are hinged to the fixing mechanism 100; a rotating shaft 230 is connected to the second connecting rod 220, and a hole that matches the rotating shaft 230 is opened on the first connecting rod 210; a limiting ring 240 that is coaxially arranged with the rotating shaft 230 is rotatably connected to the first connecting rod 210, and the side wall of the rotating shaft 230 A first protrusion 231 is provided on it, and a second protrusion 241 is provided on the inner wall of the limiting ring 240; a positioning pin 250 is connected to the first connecting rod 210, and a plurality of positioning grooves cooperating with the positioning pin 250 are provided in a circular array on the side wall of the limiting ring 240. When the positioning pin 250 is located in the positioning groove, the limiting ring 240 does not rotate relative to the first connecting rod 210; when the first protrusion 231 abuts against the second protrusion 241, the angle between the first connecting rod 210 and the second connecting rod 220 toward the fixing mechanism 100 cannot continue to decrease.
[0037] The working mechanism of the postoperative auxiliary recovery device for thyroid cancer patients provided in this embodiment is as follows:
[0038] When in use, the fixing mechanism 100 is worn on the neck so that the first limiting mechanism 200 is placed on the left and right sides of the neck. When the patient tilts his head left or right, the angle between the first connecting rod 210 and the second connecting rod 220 in the direction of the head tilt becomes smaller. The positioning pin 250 is connected to the first connecting rod 210 by a thread. The positioning pin 250 is removed from the first connecting rod 210. At this time, the positioning pin 250 moves out of the positioning groove on the limiting ring 240, so that the limiting ring 240 can rotate relative to the first connecting rod 210. By rotating the limiting ring 240, the moving gap between the second protrusion 241 inside it and the first protrusion 231 on the rotating shaft 230 is changed. According to the patient's postoperative recovery time or needs Adjust the gap between the first protrusion 231 and the second protrusion 241. After the adjustment is completed, tighten the positioning pin 250 onto the first connecting rod 210, and make the positioning pin 250 in the limiting ring 240. At this time, the limiting ring 240 no longer rotates relative to the first connecting rod 210, thereby completing the adjustment of the first limiting mechanism 200. After the first limiting mechanism 200 is adjusted, the degree of reduction of the angle between the first connecting rod 210 and the second connecting rod 220 is limited. After adjusting the relative rotation angle of the first connecting rod 210 and the second connecting rod 220 according to the patient's postoperative time and the degree of wound healing, the angle of the patient's head tilt is limited when the patient does the recovery action of tilting the head left and right, thereby avoiding excessive head tilt angles that cause wound tearing.
[0039] Regarding how to protect the patient's head from moving forward and backward, specifically:
[0040] It also includes a second limiting mechanism 400, which includes a plurality of hinged seats 420 connected to the fixing mechanism 100, and the first connecting rod 210 and the second connecting rod 220 are both hinged to the fixing mechanism 100 through the hinged seats 420; the hinged seat 420 is internally slidably connected to a limiting frame 430, and a sliding rod 433 is provided on the limiting frame 430, and a locking plate 434 is connected to the end of the sliding rod 433, and an arc-shaped sliding groove cooperating with the sliding rod 433 and the locking plate 434 is opened on the fixing mechanism 100; the limiting frame 430 can slide axially along the sliding rod 433 so that the locking plate 434 abuts against the end wall of the arc-shaped sliding groove.
[0041] The number of the articulated seat 420 can be one or two, and the articulated seat 420 is connected to a connecting shaft 410, and the first connecting rod 210 or the second connecting rod 220 is connected to the corresponding articulated seat 420 through the corresponding connecting shaft 410. When the number of the articulated seat 420 is one, the slide bar 433 on the limit frame 430 connected to the inside of the articulated seat 420 rotates on the fixing mechanism 100. When the number of the articulated seat 420 is two, the number of the limit frames 430 corresponding to the articulated seat 420 is also two, and the slide bars 433 on the two limit frames 430 slide in the same arc-shaped slide groove, and the center of the arc-shaped slide groove track is The axial distances from the two slide bars 433 are equal, so that the two slide bars 433 can revolve along the arc-shaped groove. At this time, the patient can perform recovery movements of lowering and raising the head. When the patient's wound recovery does not meet the training standard for the recovery movement of lowering and raising the head, the limit frame 430 is controlled to move axially along the slide bar 433 so that the locking plate 434 at its end abuts against the end face of the arc-shaped groove on the fixing mechanism 100. Under the action of the friction force between the locking plate 434 and the end face wall of the arc-shaped groove, the slide bar 433 cannot rotate axially relative to the fixing mechanism 100, so that the patient cannot perform recovery movement training of lowering and raising the head at this time.
[0042] Among the optional methods of this embodiment, the more preferred ones are:
[0043] The second limiting mechanism 400 also includes a locking block 431, which has a long hole and a screw 432 connected to the long hole; when the locking plate 434 abuts against the end wall of the arc-shaped slide groove, the screw 432 abuts against the hinge seat 420 and is locked so that the limiting frame 430 does not move relative to the hinge seat 420.
[0044] When the limit frame 430 slides axially along the sliding rod 433 in the direction away from the fixing mechanism 100 so that the locking plate 434 abuts against the end wall of the arc-shaped sliding groove, the manually movable screw 432 is moved in the long hole so that the side wall of the screw 432 fits against the hinge seat 420. At this time, the nut at the end of the screw 432 is tightened so that the relative position between the screw 432 and the locking block 431 no longer changes, so that the locking plate 434 can stably abut against the end wall of the arc-shaped sliding groove, so that the second limit mechanism 400 can stably limit the fixing mechanism 100, so that the patient cannot perform training movements of lowering and raising the head.
[0045] Among the optional methods of this embodiment, the more preferred ones are:
[0046] Two groups of the first limiting mechanism 200 and the second limiting mechanism 400 are provided, and the two groups of the first limiting mechanism 200 and the second limiting mechanism 400 are symmetrically arranged on both sides of the fixing mechanism 100 .
[0047] By providing two first limiting mechanisms 200 and a second limiting mechanism 400, the patient can be subjected to symmetrical limiting forces when performing recovery training, thereby ensuring a protective effect for the patient during recovery training.
[0048] Regarding the structure of the fixing mechanism 100, specifically:
[0049] The fixing mechanism 100 comprises: an upper fixing ring 110 ; a lower fixing ring 120 ; and a neck strap 130 which is sleeved on the patient's neck and connected between the upper fixing ring 110 and the lower fixing ring 120 .
[0050] The upper fixing ring 110 and the lower fixing ring 120 are both made of hard materials to ensure that force can be stably applied to the first connecting rod 210 and the second connecting rod 220. The neck strap 130 is made of elastic breathable fabric to ensure that the neck strap 130 can cover the patient's neck after the patient wears it, so that the wound on the neck can be better protected.
[0051] Among the optional methods of this embodiment, the more preferred ones are:
[0052] The fixing mechanism 100 further includes: two arc-shaped fixing plates 160, which are respectively placed on the shoulders of the patient; and a first fixing belt 170, which is respectively put on the armpits of the patient.
[0053] There are two arc-shaped fixing plates 160, which are placed on the two shoulders of the patient respectively. The first fixing belt 170 is passed through the patient's armpits, and the first buckle 171 is fastened to fix the arc-shaped fixing plates 160 on the patient's shoulders, thereby further increasing the connection firmness between the fixing mechanism 100 and the patient's neck.
[0054] Among the optional methods of this embodiment, the more preferred ones are:
[0055] The fixing mechanism 100 also includes an arc-shaped rod 140; openings are provided on the upper fixing ring 110, the lower fixing ring 120 and the neck strap 130, and the arc-shaped rod 140 can be inserted into the openings of the upper fixing ring 110 and the lower fixing ring 120; nuts 150 are threadedly connected on both sides of the openings on the upper fixing ring 110 and the lower fixing ring 120, and the nuts 150 can be locked to the arc-shaped rod 140.
[0056] An opening is provided between the upper fixing ring 110, the neck strap 130 and the lower fixing ring 120, and the upper fixing ring 110 and the lower fixing ring 120 can be deformed. The upper fixing ring 110 and the lower fixing ring 120 are pried apart to make the opening larger, so that the fixing mechanism 100 can be worn on the neck. Velcro is provided on both sides of the opening on the neck strap 130. After wearing, the two side parts of the neck strap 130 located at the opening are connected by the Velcro. At this time, the neck strap 130 and the patient's neck are connected and fixed, and then the two arc rods 140 are respectively inserted into the upper fixing ring 110 and the lower fixing ring 120 at the positions of the openings, and then the two arc rods 140 are respectively locked on the upper fixing ring 110 and the lower fixing ring 120 by the nuts 150, so that the shapes of the upper fixing ring 110 and the lower fixing ring 120 no longer change, and the wearing of the fixing mechanism 100 is completed at this time.
[0057] Regarding the structure of the protection mechanism 300, specifically:
[0058] The neckband 130 is provided with a protection mechanism 300 , which includes a fixing block 311 , and a ventilation groove 314 is provided inside the fixing block 311 ; a second fixing belt 312 is connected to the fixing block 311 , and the second fixing belt 312 is sleeved on the neckband 130 .
[0059] The fixing block 311 is made of rubber or other materials with the same properties as rubber. A ventilation groove 314 is provided on the side of the fixing block 311 facing the neck. The ventilation groove 314 is placed at a position directly opposite the serial port, and then the second lock buckle 313 is fastened so that the second fixing belt 312 is firmly attached to the patient's neck. When the fixing block 311 is covered on the wound, the skin around the wound can be pressed to prevent the wound from being pulled and torn when the patient does the head tilt recovery exercise.
[0060] Among the optional methods of this embodiment, the more preferred ones are:
[0061] The protection mechanism 300 also includes an arc-shaped piston cylinder 320 and an arc-shaped piston rod 330 sliding on the arc-shaped piston cylinder 320; the arc-shaped piston cylinder 320 is connected to the second connecting rod 220, the arc-shaped piston rod 330 is connected to the first connecting rod 210, and an exhaust pipe 315 is connected between the arc-shaped piston cylinder 320 and the ventilation groove 314; the arc-shaped piston cylinder 320 is connected to an intake pipe 340, and both the intake pipe 340 and the exhaust pipe 315 are provided with a one-way valve.
[0062] The arc-shaped piston cylinder 320 is connected to the ventilation groove 314 in the fixed block 311 through the exhaust pipe 315. When the patient does a head tilt movement, the first connecting rod 210 swings relative to the second connecting rod 220 so that the arc-shaped piston rod 330 slides inside the arc-shaped piston cylinder 320, so that the arc-shaped piston cylinder 320 draws external air through the intake pipe 340 and blows the air into the ventilation groove 314 in the fixed block 311 through the exhaust pipe 315, so that the wound is ventilated, so that the sweat that may appear near the wound when the patient is doing recovery training can be quickly dried, so that the wound will not be soaked by sweat and cause infection and other situations.
[0063] Among the optional methods of this embodiment, the more preferred ones are:
[0064] The air inlet pipe 340 is also provided with a valve 341 , and a filter element 342 is connected to the air inlet end of the air inlet pipe 340 .
[0065] The setting of the filter element 342 purifies the external air extracted by the arc-shaped piston cylinder 320, so that the air blown to the wound does not contain harmful substances such as bacteria, thereby preventing the wound from being contaminated. The valve 341 can adjust the opening of the air inlet pipe 340. When the opening of the air inlet pipe 340 is reduced, the relative sliding resistance between the arc-shaped piston rod 330 and the arc-shaped piston cylinder 320 increases, thereby changing the resistance of the patient's head tilt movement, allowing the patient to adjust his resistance when doing recovery exercises, thereby improving the effect of recovery training.
