Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary medical devices, and in particular to an auxiliary device for HIFU ablation of posterior wall uterine fibroids. Background Art

[0002] The HIFU ablation surgery for uterine fibroids is a technology that uses ultrasonic energy to focus on tumor tissue and cause tumor cell necrosis through thermal effect. In the HIFU surgery, the operating table is specially designed with an opening in the center and a HIFU structure installed in the opening. During the operation, the patient will lie prone on the bed with the abdomen aligned with the opening on the operating table. The doctor then emits ultrasonic energy through the above-mentioned HIFU structure. These ultrasonic energies will pass through the patient's soft tissue and focus precisely on the uterine fibroid tissue. At the focus, the ultrasonic energy will be rapidly converted into heat energy, causing the fibroid tissue to rapidly heat up and undergo coagulative necrosis.

[0003] During the operation, the patient may feel slight local distension and needle-like pain. In order to prevent the patient from moving on his own due to pain or discomfort, which would lead to inaccurate surgical position, the patient needs to be limited. After searching, a Chinese patent with patent publication number CN222341510U discloses an auxiliary device for HIFU ablation of uterine fibroids. However, the patent only uses two fixing plates to simply limit and fix the patient, and the fixation effect is not good. This simple fixation method cannot fully ensure the stability of the patient during the operation, and it is easy to cause the surgical position to shift. Once the surgical position shifts, it may not only affect the surgical effect, but also cause unnecessary damage and pain to the patient due to the wrong focusing point of ultrasonic energy.

[0025] Reference Figure 1 as well as Figures 6 to 10, the two movable plates 29 are provided with a gap-filling component for filling the gap between the inflated first airbag 6 and the mounting groove 23 to prevent the patient from feeling uncomfortable due to the gap between the inflated first airbag 6 and the mounting groove 23 when lying prone on the HIFU operating table 1.

The locking components include two first screw holes and a plurality of second screw holes. The two first screw holes are respectively penetrated and arranged at the top ends of the two movable plates 29 near the sides. The first screw holes are located away from the first airbag 6. The plurality of second screw holes are respectively penetrated and arranged on the inner top walls of the two embedding grooves 24. The spacing between each two second screw holes is the same as the width of the adjustment plate 30. A fixing bolt 25 is threadedly connected in one of the second screw holes on the two embedding grooves 24, and the two embedding grooves 24 are respectively threadedly connected to the first screw holes on the two movable plates 29 through the fixing bolts 25.

[0026] Reference Figure 1 , Figure 6 and Figure 7 A side-lying auxiliary mechanism is provided on the HIFU operating bed 1, which is used to cooperate with the upwardly moved first airbag 6 to change the patient's upper body from a prone position to a side-lying position. The side-lying auxiliary mechanism includes a clamp 22, and an L-shaped fixing plate 8 is installed on the clamp 22. The L-shaped fixing plate 8 is clamped on one of the groups of grooves by the clamp 22. The clamp 22 is a prior art, and its specific structural design is no longer repeated here. A third electric telescopic rod 21 is installed on the side of the L-shaped fixing plate 8 facing the HIFU operating bed 1, and a support plate 9 is installed on the output end of the third electric telescopic rod 21. The position of the support plate 9 corresponds to the position of the mounting groove 23.

[0027] In the present invention, before the patient lies prone on the HIFU operating table 1, it is necessary to first unscrew the two fixing bolts 25, and manually push the two first airbags 6 according to the patient's body shape, so as to adjust the positions of the two first airbags 6. Since the mounting plate 28 and the movable plate 29 are magnetically connected by the first magnetic block 34 and the second magnetic block 35, when the first airbag 6 moves and drives the two mounting plates 28 to move, the two movable plates 29 will also move accordingly, so that the fifth electric telescopic rod 31 on the movable plate 29 also moves with the mounting plate 28. After the position adjustment of the first airbag 6 is completed, the second electric telescopic rod 31 on the movable plate 29 is controlled to move. The two third air pumps 4 inflate the two first airbags 6 respectively until the height of the upper surface of the inflated first airbags 6 is flush with the upper surface of the HIFU operating table 1, and then the fifth electric telescopic rod 31 is used to move the adjustment plate 30 that has been moved out of the embedded groove 24 upward until the adjustment plate 30 is flush with the upper surface of the HIFU operating table 1, so that the adjustment plate 30 can fill the gap between the inflated first airbag 6 and the mounting groove 23 (that is, make up for the height difference between the adjustment plate 30 and the first airbag 6), thereby effectively improving the patient's comfort when lying prone.

[0028] When the mounting plate 28 and the movable plate 29 are moved, it is necessary to ensure that the distance between the mounting plate 28 and the movable plate 29 is a multiple of the width of the adjustment plate 30, so that the upper surface of the adjustment plate 30 that is moved out of the embedded groove 24 can be completely exposed, to avoid that a single adjustment plate 30 is not completely leaked out and cannot be smoothly moved up under the restriction of the embedded groove 24, and thus cannot completely fill the gap between the inflated first airbag 6 and the mounting groove 23. Since the spacing between each two second screw holes is the same as the width of the adjustment plate 30, the first screw hole on the movable plate 29 after the movement must correspond to the position of a second screw hole. At this time, the fixing bolt 25 is threadedly connected in the corresponding first screw hole and the second screw hole, thereby completing the alignment of the two movable plates 2 9, after completing the above operations, the positions of the two first airbags 6 will correspond to the patient's chest position, and then the end of the restraint belt 13 away from the first air pump 2 and the second air pump 3 will be pulled out from the movable groove 18, and then the patient will be allowed to lie prone on the HIFU operating table 1, and ensure that the patient's uterine position corresponds to the position of the HIFU structure on the HIFU operating table 1. At this time, the patient's chest will be placed on the two first airbags 6, and the first airbags 6 can fit the patient's body curve, reduce the compression of the patient's chest during the long operation, and thus reduce the patient's discomfort (since the position of the HIFU structure on the HIFU operating table 1 is fixed, the chest support mechanism can be adapted to patients of different body shapes by adjusting the position of the first airbags 6).

[0029] In order to prevent the patient from moving due to his / her own movement or pain during the operation, which may lead to an inaccurate surgical position, the patient needs to be limited before the operation. At this time, the restraint belt 13 is passed over the patient, and the end of the restraint belt 13 away from the first air pump 2 and the second air pump 3 is passed through the corresponding movable groove 18 (at this time, the two ends of the restraint belt 13 are respectively in the two movable grooves 18), and then the two second electric telescopic rods 16 are controlled to make the two squeezing blocks 17 move downward and squeeze the restraint belt 13 until the two ends of the restraint belt 13 are squeezed and fixed, so that the restraint belt 13 can limit the vertical movement of the patient, and then the two first electric telescopic rods 10 are controlled to The two extrusion arc plates 11 are driven to extrude the restraint belt 13. Through the extrusion of the two extrusion arc plates 11 on both sides of the patient, the restraint belt 13 can limit the lateral movement of the patient, thereby effectively improving the fixation effect on the patient. When the restraint belt 13 is fixed, the first air pump 2 is controlled to inflate and expand the multiple second airbags 19. The expansion of the second airbags 19 can improve their fit with the patient, ensuring that the restraint belt 13 can tightly wrap the patient's body parts. At the same time, by inflating and pressurizing the second airbags 19, the restraint effect of the restraint belt 13 on the patient will also be enhanced, thereby further improving the fixation effect on the patient.

[0030] After the restraint is completed, the patient can be operated on through the HIFU structure on the HIFU operating table 1. Since the operation will last for 0.5-1.5 hours, the discomfort of the patient's waist being continuously restrained will gradually increase with time. Therefore, after the second airbag 19 is expanded for a period of time, the second airbag 19 is contracted by controlling the first air pump 2. At the same time, the second airbag 20 is inflated and expanded by controlling the second air pump 3. Since the multiple second airbags 19 and the multiple third airbags 20 are staggered with each other, the extrusion positions of the second airbag 19 and the third airbag 20 are different, so that the patient can be continuously restrained and fixed while avoiding the patient's discomfort due to continuous local pressure, which effectively reduces the patient's discomfort. In addition, through the staggered expansion and contraction of the second airbag 19 and the third airbag 20, a certain massage effect can be played on the patient's restraint position, thereby further reducing the patient's discomfort.

[0031] After the operation, if the patient is too weak to get up on his own, the patient's deflection direction can be selected according to the patient's physical condition. The medical staff then clamps the L-shaped fixing plate 8 in the groove on one side of the HIFU operating table 1 through the clamp 22 (for example, if one side of the patient is injured, the L-shaped fixing plate 8 is located on the uninjured side of the patient), and then controls the third electric telescopic rod 21 to move the support plate 9 toward the patient until the support plate 9 is against the patient's side. Then, the fourth electric telescopic rod 27 is controlled to move the mounting plate 28 away from the support plate 9 upward. Since the fourth electric telescopic rod 27 is rotatably connected to the bottom end of the mounting plate 28 through the second rotating portion, and the patient is pressed down on the first airbag 6, as the mounting plate 28 continues to move upward, the mounting plate 28 and the mounting plate 28 are The first airbag 6 on the plate 28 will tilt toward the patient and push one side of the patient upward, thereby changing the patient's upper body from a prone position to a lateral position. Since the lateral position makes it easier for medical staff to lift the patient up, this position change simplifies the process of medical staff lifting the patient up, thereby effectively reducing the burden on medical staff. Since the rubber sheet 7 at the top of the two first airbags 6 is located at the contact point of the two first airbags 6, when a single first airbag 6 moves up and rotates, the rubber sheet 7 can prevent the patient's skin and flesh from being stuck in the gap between the rotated first airbag 6 and the non-rotated first airbag 6, thereby avoiding skin compression injuries or discomfort caused by the gap between the two first airbags 6 during the position change process.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
