Description

Technical Field

[0001] The present invention relates to the technical field of facial plastic surgery auxiliary tools, and in particular to a surgical auxiliary facial plastic surgery device. Background Art

[0002] After mandibular angle or zygomatic bone surgery, it is essential to use a wrap to support and fix the face. This wrap not only helps stabilize the bone position and prevent postoperative displacement, but also effectively reduces swelling and ensures the symmetry of the two sides of the face, thereby optimizing the overall recovery effect and promoting a faster and more ideal healing process. In addition, the uniform compression provided by the pressure mask helps reduce postoperative discomfort and further enhances the patient's recovery experience.

[0003] After mandibular angle or zygomatic bone plastic surgery, using a wrap to support and fix the face is an important part of the recovery process. However, it does not need to be worn all day during recuperation at home. Doctors usually recommend appropriate wearing time and frequency based on specific circumstances to ensure the best results. Since patients may not have professional wrapping techniques, improper wrapping may occur when they do it themselves, resulting in improper fixation and affecting the recovery effect.

[0004] Based on the above situation, the present invention proposes a surgical-assisted facial plastic surgery device. Summary of the invention

[0008] Furthermore, one side of the pawl is set as an inclined surface, and the front and rear parts of the other side of the pawl are respectively set as an inclined surface and a straight surface. When the ratchet acts on the inclined surface of the pawl, the ratchet squeezes the pawl to slide relative to the unlocking rod toward the side away from the ratchet.

[0009] Furthermore, it also includes a support base, which is fixed to a side of the mounting frame away from the adjustment frame, and the support base is slidably connected to a pull rod symmetrically distributed along the support base, and the support base is provided with an arc-shaped slide groove symmetrically distributed along the support base, and a first magnetic block is slidably connected in the arc-shaped slide groove of the support base, and the pull rod is fixed to a second magnetic block, and the second magnetic block is magnetically matched with the adjacent first magnetic block.

[0010] Furthermore, it also includes a pull rope corresponding to the adjustment frame, the pull rope is fixedly connected to the corresponding adjustment frame, a pull block is slidably connected in the arc-shaped slide groove of the support base, the pull block is fixedly connected to the pull rope on the same side, and a second spring is fixedly connected between the first magnetic block and the adjacent pull block.

[0011] Furthermore, it also includes a slider symmetrically distributed along the mounting frame, the slider is slidably connected to the mounting frame, the slider is slidably connected to a baffle rod for shifting the adjacent adjusting frame, the baffle rod is extrusion-fitted with the adjacent adjusting frame, a tension spring is fixed between the slider and the adjacent baffle rod, the baffle rod is provided with a protrusion, the mounting frame is slidably connected to a baffle frame, the baffle frame is provided with latching teeth symmetrically distributed along the baffle frame, and the latching teeth of the baffle frame are mutually engaged with the protrusion on the same side.

[0012] Furthermore, the barrier rod is configured to be U-shaped.

[0013] Furthermore, a side of the blocking rod close to the protrusion is provided with an inclined surface, the inclined surface of the blocking rod contacts the adjacent adjustment rack, and a side of the blocking rod away from the protrusion is used to block the adjacent adjustment rack.

[0014] Furthermore, it also includes a clamping strip corresponding to the first magnetic block, the clamping strip is fixedly connected to the corresponding first magnetic block, a limiting step is provided in the arc-shaped slide groove of the support base on one side close to the adjacent first magnetic block, an elastic telescopic block is slidably connected in the pull block, the clamping teeth of the clamping strip are squeezed and matched with the elastic telescopic block, and the clamping teeth of the clamping strip limit the unidirectional movement of the elastic telescopic block toward the side away from the adjacent first magnetic block.

[0015] Furthermore, it also includes a clamping rod, which is fixed to one side of the guide frame close to the gear. The clamping rod is squeezed and fitted with the gear to slow down the rotation speed of the gear. A third spring is fixed between the clamping rod and the adjacent guide frame.

[0016] The beneficial effect is that the present invention ensures that the covering belt body is in the maximum expansion state in the initial state through the adjustment effect of the adjustment frame and the magnetic attraction between the first magnetic block and the second magnetic block, which is convenient for wearing. During the wearing process, the lower part of the covering belt body automatically rebounds upward, so that the covering belt body tightly covers the patient's chin, providing a more fitting and comfortable wearing experience.

[0017] The present invention utilizes the adjustment function of the adjustment rod and the one-way locking mechanism of the ratchet and the pawl to achieve precise control of the tightening strength of the left and right sides of the covering belt body, which can quickly adapt to different face shapes, making it convenient for users to adjust the covering by themselves. At the same time, it can prevent the covering belt body from being accidentally loosened, and the setting of the unlocking rod can quickly reset it.

[0018] The present invention provides components such as a baffle rod, so that after the adjustment frame adjusts the tightening range according to the size of the user's face, it does not need to be completely reset when opening the covering belt body, but only needs to be opened within a small range. This not only shortens the adjustment stroke, but also facilitates quick wearing and removal during subsequent repeated use, saving time and energy, and has the significance of personalized use.

[0019] The present invention limits the maximum sliding range of the first magnetic block to ensure that no matter how the adjustment is made, the first magnetic block can be quickly reset when the adjustment frame is not completely reset, thereby increasing the reliability and safety of the system.

[0020] Medical staff can perform a "zero reset" through simple steps, such as pulling up the retaining frame and the elastic telescopic block, to restore the device to its original state, making it easier for the hospital to recycle and reuse it.

[0021] The present invention reduces the rotation speed of the gear by extruding and matching the wedge-shaped portion of the clamping rod with the gear, avoids the rapid rebound impact of the adjustment frame caused by the rapid rebound of the first spring, reduces the vibration to the user's head, and improves the comfort of use.

DETAILED DESCRIPTION

[0035] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Embodiment 1: A surgically assisted facial plastic surgery device, such as Figure 1-Figure 4As shown, it includes a mounting frame 1, and the left and right sides of the mounting frame 1 are slidably connected with adjustment frames 2, a head pad 101 is fixedly connected to the middle of the bottom of the mounting frame 1, and a soft cushion is arranged in the middle of the head pad 101 so that the user's head can contact it comfortably, a covering belt body 3 is fixedly connected between the two adjustment frames 2, and the left and right sides of the head pad 101 are provided with space for the covering belt body 3 to move, an adjustment rod 4 is rotatably connected in the middle of the mounting frame 1, and a gear 5 is fixedly connected in the middle of the adjustment rod 4, and a guide frame 7 is fixedly connected to the left front and right rear of the mounting frame 1, the left adjustment frame 2 is slidably connected to the guide frame 7 at the left front, and the right adjustment frame 2 is slidably connected to the guide frame 7 at the right rear, and a first spring 8 is fixedly connected between the adjustment frame 2 and the adjacent guide frame 7. , racks are provided on the bottom surface of the left adjustment frame 2 and the top surface of the right adjustment frame 2, the racks of the adjustment frame 2 are meshed with the gear 5, an unlocking rod 6 is slidably connected to the middle of the front side of the mounting frame 1 along the front-to-back direction, a fixed cover 601 is fixedly connected to the middle of the front side of the mounting frame 1, the fixed cover 601 is slidably connected to the unlocking rod 6, a ratchet 602 is fixedly connected to the front of the adjusting rod 4, a pawl 603 is slidably connected to the upper rear side of the unlocking rod 6 along the up-down direction, the left side of the pawl 603 is set as an inclined surface, and the front and rear of the right side of the pawl 603 are respectively set as an inclined surface and a straight surface, when the ratchet 602 acts on the inclined surface of the pawl 603, the ratchet 602 squeezes the pawl 603 to slide upward relative to the unlocking rod 6, and an elastic member 604 is fixedly connected between the fixed cover 601 and the unlocking rod 6.

[0037] like Figure 5 and Figure 6 As shown, it also includes a support base 9, which is fixed to the bottom side of the mounting frame 1. The lower part of the support base 9 is slidably connected to a pull rod 10 symmetrically distributed along the left and right sides of the support base 9 in the up and down directions. The two pull rods 10 are distributed in an eight-shaped shape. The lower part of the support base 9 is provided with an arc-shaped slide groove symmetrically distributed along the left and right sides of the support base 9. A first magnetic block 11 is slidably connected in the arc-shaped slide groove of the support base 9. A second magnetic block 12 is fixed to the upper part of the pull rod 10. The second magnetic block 12 is magnetically matched with the adjacent first magnetic block 11. A pull rope 13 is fixed to one side of the adjustment frame 2. A pull block 14 is slidably connected in the arc-shaped slide groove of the support base 9. The pull block 14 is fixed to the pull rope 13 on the same side. A second spring 15 is fixed between the first magnetic block 11 and the adjacent pull block 14.

[0038] Initially, under the magnetic attraction of the first magnetic block 11 and the second magnetic block 12, the pull rod 10 pulls down the lower part of the covering belt body 3, and the left and right sides of the covering belt body 3 are pulled outward by the left and right adjustment frames 2 respectively, so that the covering belt body 3 is in the maximum expansion state. When wearing the device, first place the entire head between the covering belt body 3 and the head pad 101, so that the covering belt body 3 surrounds the face, and the head pad 101 is supported on the top of the head. Then, the adjustment rod 4 is turned, and the adjustment rod 4 drives the gear 5 to rotate. Since the gear 5 is meshed with the racks on the upper and lower sides, the racks on the upper and lower sides respectively drive the adjustment frames 2 on the left and right sides to move along their respective The guide frame 7 slides toward the side close to the adjusting rod 4, the first spring 8 is compressed, and the adjusting frames 2 on the left and right sides respectively drive the left and right sides of the covering belt body 3 to move toward each other until the left and right sides of the covering belt body 3 are in contact with the patient's cheeks and tighten the cheeks to an appropriate strength. Since the left side surface of the pawl 603 is set as an inclined plane and the rear right side surface of the pawl 603 is set as a vertical plane, the adjusting rod 4 can only drive the ratchet 602 to rotate clockwise during the adjustment process and cannot rotate counterclockwise to reset, thereby making it impossible for the adjusting frame 2 to reset, and further making it impossible for the left and right sides of the covering belt body 3 to open and reset.

[0039] When the adjusting rod 4 is turned to make the adjusting frame 2 slide, the adjusting frame 2 pulls the pulling block 14 through the pulling rope 13 to slide upward along the arc-shaped slide groove of the supporting base 9, and the pulling block 14 pulls the first magnetic block 11 through the second spring 15 to slide along the arc-shaped slide groove in the direction away from the second magnetic block 12, so that the first magnetic block 11 no longer attracts the second magnetic block 12, and under the action of the rebound force of the lower part of the covering belt body 3, the lower part of the covering belt body 3 automatically rebounds upward, so that the covering belt body 3 tightly covers the patient's chin.

[0040] When resetting is required, the unlocking rod 6 is pressed backward, the elastic member 604 is stretched, and the unlocking rod 6 drives the pawl 603 to move backward, so that the rear part of the pawl 603 disengages from the teeth gap of the ratchet 602, and the front part of the pawl 603 remains in the teeth gap of the ratchet 602 for positioning. Since the left side surface of the pawl 603 is set as an inclined surface, and the right side surface of the front part of the pawl 603 is also set as an inclined surface, the adjusting rod 4 can drive the ratchet 602 to rotate counterclockwise, so that the adjusting frame 2 can be reset, and then the left and right sides of the covering belt body 3 can be opened and reset. When the adjusting frame 2 is reset, the pull rope 13 is completely released, and the first magnetic block 11, the pull block 14 and the second spring 15 as a whole slide in the opposite direction along the arc-shaped slide groove of the support base 9 to reset.

[0041] In summary, the present invention ensures that the covering belt body 3 is in the maximum expansion state in the initial state through the adjustment effect of the adjustment frame 2 and the magnetic attraction between the first magnetic block 11 and the second magnetic block 12, so as to be easy to wear. During the wearing process, the lower part of the covering belt body 3 automatically rebounds upward, so that the covering belt body 3 tightly covers the patient's chin, providing a more fitting and comfortable wearing experience.

[0042] The present invention utilizes the adjustment function of the adjustment rod 4 and the one-way locking mechanism of the ratchet 602 and the pawl 603 to achieve precise control of the tightening strength of the left and right sides of the covering belt body 3, which can quickly adapt to different face shapes, thereby facilitating users to adjust the covering by themselves. At the same time, it can prevent the covering belt body 3 from being accidentally loosened, and the setting of the unlocking rod 6 can quickly reset it.

[0043] Embodiment 2: Based on embodiment 1, Figure 8-Figure 11 As shown, it also includes a slider 16 symmetrically distributed along the mounting frame 1, the slider 16 is slidably connected to the rear side of the mounting frame 1, a blocking rod 17 is slidably connected to the slider 16 along the front-to-back direction, the blocking rod 17 is set to a U-shape, a tension spring 18 is fixedly connected between the slider 16 and the adjacent blocking rod 17, a protrusion 19 is provided on the side of the blocking rod 17 close to the adjacent slider 16, a slope is provided on the side of the blocking rod 17 close to the protrusion 19, the slope of the blocking rod 17 contacts the adjacent adjustment frame 2, and the side of the blocking rod 17 away from the protrusion 19 is used to block the adjacent adjustment frame 2, and a blocking frame 20 is slidably connected to the rear side of the mounting frame 1 along the up-down direction, the blocking frame 20 is provided with latching teeth symmetrically distributed along the blocking frame 20, and the latching teeth of the blocking frame 20 are engaged with the protrusion 19 on the same side.

[0044] When the adjusting rod 4 is turned to make the adjusting frame 2 slide, the adjusting frame 2 first squeezes the inclined surface of the blocking rod 17, so that the blocking rod 17 slides backward relative to the slider 16, the tension spring 18 is stretched, and the blocking rod 17 drives the protrusion 19 to disengage from the teeth of the blocking frame 20 backward. The adjusting frame 2 can push the blocking rod 17 to move synchronously, and the blocking rod 17 drives the slider 16, the tension spring 18 and the protrusion 19 to move synchronously.

[0045] When the unlocking lever 6 is pressed backward to release the cheek from the covering belt body 3, the first spring 8 rebounds and drives the adjusting frame 2 to slide in the opposite direction, so that the adjusting frame 2 is disengaged from the inclined surface of the blocking rod 17. At this time, the tension spring 18 is reset and drives the blocking rod 17 to slide forward relative to the slider 16. The blocking rod 17 drives the protrusion 19 forward to engage in the corresponding tooth of the blocking frame 20. In this way, the adjusting frame 2 slides in the opposite direction until it contacts the side of the blocking rod 17 away from the inclined surface.

[0046] In short, the present invention provides a baffle 17 so that after the adjustment frame 2 adjusts the tightening range according to the size of the user's corresponding face shape, when it is necessary to open the covering belt body 3, the adjustment frame 2 does not need to be completely reset, but only needs to be reset to contact with the side of the baffle 17 away from the protrusion 19, so that the covering belt body 3 does not need to be opened to the maximum range, but only needs to be fixedly opened in a small range, thereby shortening the adjustment stroke and facilitating subsequent repeated use. The user can quickly put on and take off the device according to the size of his or her face, saving time and energy, and having the significance of personalized use.

[0047] When the hospital needs to recycle this device, it needs to be "reset to zero". The specific operation is as follows: the medical staff pulls the baffle frame 20 upwards so that the locking teeth of the baffle frame 20 disengage from the protrusion 19, and the first spring 8 is completely reset, driving the adjustment frame 2 to be completely reset. During the resetting process of the adjustment frame 2, it contacts the baffle rod 17 and pushes the baffle rod 17 to move synchronously in the opposite direction. The baffle rod 17 drives the slider 16, the tension spring 18 and the protrusion 19 to move synchronously in the opposite direction. Finally, the medical staff pulls the baffle rod 17 to completely reset, so that the inclined surface of the baffle rod 17 contacts the adjustment frame 2, and then pushes the baffle frame 20 downward so that the locking teeth of the baffle frame 20 engage with the protrusion 19.

[0048] like Figure 5-Figure 7 As shown, it also includes a clamping strip 112 corresponding to the first magnetic block 11, the clamping strip 112 is fixedly connected to the corresponding first magnetic block 11, a limiting step 111 is provided on the side of the arc-shaped slide groove of the support base 9 close to the adjacent first magnetic block 11, and an elastic telescopic block 141 is slidably connected in the pull block 14 along the up and down directions, the clamping teeth of the clamping strip 112 are squeezed and matched with the elastic telescopic block 141, and the clamping teeth of the clamping strip 112 limit the elastic telescopic block 141 from moving unidirectionally toward the side away from the adjacent first magnetic block 11.

[0049] Due to the setting of the stopper 17, the adjustment frame 2 may not be completely reset during use, resulting in the first magnetic block 11 being unable to be completely reset, and thus the pull rod 10 cannot automatically pull down the lower part of the covering belt body 3. To this end, the following specific operations are performed to enable the first magnetic block 11 to be completely reset when the adjustment frame 2 is not completely reset: When the first magnetic block 11 slides along the arc-shaped slide groove in the direction away from the second magnetic block 12, it drives the clamping strip 112 to slide synchronously. When the first magnetic block 11 slides to the limit step 111, the first magnetic block 11 cannot continue to slide, so that the clamping strip 112 cannot continue to slide. If the two sides of the covering belt body 3 are not adjusted to contact the patient's cheek at this time, further adjustment is performed so that the pull rope 13 pulls the pull block 14 to slide relative to the clamping strip 112, the second spring 15 is stretched, and the pull block 14 pulls the elastic telescopic block 141 to move synchronously. During the movement, the clamping strip 112 squeezes the elastic telescopic block 141 to intermittently shrink upward When the left and right sides of the covering belt body 3 are adjusted to contact the patient's cheeks and tightened to an appropriate strength, the adjustment is stopped. At this time, the elastic telescopic block 141 and the clamping strip 112 are engaged with each other, so that the first magnetic block 11, the pulling block 14, the elastic telescopic block 141, the second spring 15 and the clamping strip 112 form a whole. In this way, no matter how the adjustment is made, the maximum sliding range of the first magnetic block 11 will not exceed the limit ridge 111, so that when the adjustment frame 2 is not completely reset, the first magnetic block 11 can also form a whole with the pulling block 14, the elastic telescopic block 141, the second spring 15 and the clamping strip 112 for rapid short-range reset.

[0050] When the hospital needs to recycle the device, it needs to be "reset to zero". The specific operation is as follows: pull the elastic telescopic block 141 upward so that the elastic telescopic block 141 no longer jams the card strip 112, the second spring 15 resets and drives the pulling block 14 to reset, and finally release the elastic telescopic block 141, and the elastic telescopic block 141 jams the card strip 112 again.

[0051] Embodiment 3: Based on embodiment 2, Fig.12 As shown, it also includes a clamping rod 21, which is fixedly connected to one side of the guide frame 7 close to the gear 5. The side of the clamping rod 21 close to the gear 5 is set as a wedge-shaped portion. The wedge-shaped portion of the clamping rod 21 is squeezed and matched with the gear 5. When the gear 5 rotates, it must resist the resistance of the wedge-shaped portion of the clamping rod 21, thereby slowing down the rotation speed of the gear 5 and avoiding the adjustment frame 2 from rebounding quickly and hitting the user's head when the first spring 8 rebounds quickly, causing a shock to the user's head and affecting the comfort of use. A third spring 22 is fixedly connected between the clamping rod 21 and the adjacent guide frame 7.
