[0002] With the advancement of science and technology and society, medical standards are constantly developing and people's requirements are constantly increasing. In surgery, there is a transition from major surgery to minimally invasive and non-invasive surgery. Among non-invasive surgeries, there is a HIFU surgery, also called high-intensity focused ultrasound ablation, which is a surgery that does not require anesthesia. It is often used in uterine fibroid surgery. Because it does not require surgery, the impact it causes is relatively weak and fertility is preserved. This is a great blessing for some patients who want to have children.

[0003] The HIFU operation is to open a hole in the middle of the hospital bed, and install a golden disk that emits energy in the hole. There is an ultrasound image in the middle of the disk. During the operation, the patient is asked to lie on the bed with his abdomen aligned with the hole on the bed, and then the HIFU operation is performed. Since the HIFU operation does not require anesthesia, the patient is in a conscious state during the operation. The HIFU operation time is between half an hour and 3 hours. In order to avoid involuntary movement of the patient and affect positioning, auxiliary devices are needed to fix the patient.

[0004] The existing methods generally use straps or restraints to bind the patient to prevent the patient from moving. When using the straps, since the straps need to be in close contact with the patient's body, there is a certain sense of restraint, which can easily cause discomfort to the patient and easily cause strangulation marks on the patient.

[0020] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. 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.

[0021] The auxiliary device for HIFU ablation of uterine fibroids described in this embodiment is as follows: Figure 1 and Figure 2 As shown, it includes a vertically arranged first fixing plate 1, a second fixing plate 4 parallel to the first fixing plate 1 is vertically arranged on one side thereof, and the first fixing plate 1 and the second fixing plate 4 are arranged parallel to each other left and right.

[0022] A screw rod 5 is horizontally arranged between the second fixing plate 4 and the first fixing plate 1. A threaded hole threadedly matched with the screw rod 5 is opened on the second fixing plate 4. One end of the screw rod 5 passes through the threaded hole and is located on the outer side of the second fixing plate 4 (away from the side of the first fixing plate 1). If the first fixing plate 1 is located on the left side of the second fixing plate 4, the right end of the screw rod 5 is located on the right side of the second fixing plate 4.

[0023] The side surface of the first fixing plate 1 away from the second fixing plate 4 is an arc surface, and the thickness of the first fixing plate 1 is thin in the middle and thick at the upper and lower ends. The first fixing plate 1 is located on the left side of the second fixing plate 4, and a through groove communicating front and back is provided on the left side surface of the first fixing plate 1. The surface of the through groove is an arc surface, so that the left side surface of the first fixing plate 1 is a "C"-shaped arc surface, so that the first fixing plate 1 fits better with the patient's waist and has a larger contact area, thereby better restricting the patient's movement; of course, in order to improve the patient's comfort, a protective pad made of sponge is provided on the arc surface of the first fixing plate 1.

[0024] A first limiting block 9 with a circular structure is fixed to one end of the screw rod 5, and the diameter of the screw rod 5 is smaller than the diameter of the first limiting block 9. A first fixing tube 10 is sleeved on the outer side of the first limiting block 9. One end of the first fixing tube 10 is fixed to the first fixing plate 1, and a second limiting block 11 is provided at the other end of the first fixing tube 10 to prevent the first limiting block 9 from detaching. The second limiting block 11 is annular, and the inner ring diameter of the second limiting block 11 is smaller than the diameter of the first limiting block 9. The diameter of the screw rod 5 is smaller than the inner ring diameter of the second limiting block 11, so that the screw rod 5 can rotate in the inner ring of the second limiting block 11, and can prevent the first limiting block 9 from passing through the inner ring of the second limiting block 11, so that the second limiting block 11 blocks the first limiting block 9. Of course, the second limiting block 11 can also be a plurality of fixed blocks. It is evenly fixed on the inner wall of the first fixed tube 10 to block the first limit block 9; when the screw rod 5 rotates to the left, the screw rod 5 will drive the first limit block 9 to rotate in the first fixed tube 10, so that the first limit block 9 pushes the first fixed plate 1 to the left, and when the screw rod 5 rotates to the right, the first limit block 9 will drive the first fixed tube 10 to move to the right through the second limit block 11, thereby driving the first fixed plate 1 to move to the right; of course, in actual use, the connecting component can also be to change the second limit block 11 into a bearing, the inner ring of the bearing is fixed on the first limit block 9, and the outer ring of the bearing is fixed to the inner wall of the first fixed tube 10, so that the screw rod 5 can rotate, and when the screw rod 5 moves horizontally, it will drive the first fixed plate 1 to move through the first fixed tube 10. This paragraph of text as a whole constitutes a connecting component for connecting the screw rod 5 with the second fixed plate 4 and allowing the screw rod 5 to rotate independently.

[0025] A handle 6 is provided at one end of the screw rod 5 away from the first fixed plate 1. The first fixed plate 1 is located on the left side of the second fixed plate 4. The right end of the screw rod 5 is located on the right side of the second fixed plate 4. A handle 6 is fixed to the right end of the screw rod 5. The handle 6 is cylindrical and has anti-slip grooves. The screw rod 5 can be easily rotated by the handle 6. Of course, in actual use, the outer wall of the right end of the screw rod 5 can also be made without threads.

[0026] A fixing block 2 is provided between the first fixing tube 10 and the first fixing plate 1, the fixing block 2 is fixed to the first fixing tube 10, the fixing block 2 is fixed to the first fixing plate 1 through a connecting rod 3, three connecting rods 3 are provided, and the three connecting rods 3 are evenly fixed between the fixing block 2 and the first fixing plate 1 in the form of an equilateral triangle, two connecting rods 3 are located at the bottom on a horizontal line, and the other connecting rod 3 is located directly above the center line of the two connecting rods 3 at the bottom, so that the first fixing plate 1 can be in a vertical state in a natural state, and the fixing block 2 can prevent the first limit block 9 from directly contacting the first fixing plate 1.

[0027] A groove body 7 with a "C"-shaped structure is fixed to the bottom of the second fixing plate 4. The groove body 7 is a groove with a left-facing notch and no front and rear side walls. A first bolt 8 for fixing it to the hospital bed is provided at the bottom of the groove body 7. A first threaded hole that is threadedly engaged with the screw of the first bolt 8 is opened at the bottom of the groove body 7. The screw of the first bolt 8 passes through the first threaded hole and is located inside the groove body 7. During use, the edge of the hospital bed is placed inside the groove body 7, and then the first bolt 8 is screwed upward so that the screw of the first bolt 8 abuts against the bottom of the hospital bed, thereby making the top of the groove body 7 closely adhere to the top of the hospital bed, fixing the groove body 7 to the hospital bed, and fixing the second fixing plate 4 to the hospital bed. The whole paragraph constitutes a fixing mechanism for fixing the second fixing plate 4 to the hospital bed.

[0028] As Figure 3 shown, a fixing column 13 is fixed to the bottom of the second fixing plate 4. A second fixing tube 14 is independently sleeved outside the fixing column 13. The bottom end of the second fixing tube 14 is fixed to the top of the groove body 7. A second bolt 12 for preventing the fixing column 13 from rotating is provided on the second fixing tube 14. A second threaded hole that is threadedly engaged with the screw of the second bolt 12 is opened on the side wall of the second fixing tube 14. The screw of the second bolt 12 passes through the second threaded hole and abuts against the fixing column 13, thereby preventing the fixing column 13 from rotating inside the second fixing tube 14. By rotating the fixing column 13, the angles of the second fixing plate 4 and the first fixing plate 1 can be adjusted. When restricting the patient's leg, the first fixing plate 1 can be better fitted to the patient's leg.

[0029] A bearing is provided between the fixing column 13 and the second fixing tube 14. There are two bearings. Bearings are sleeved on both the top and bottom of the fixing column 13. The outer ring of the bearing is fixed to the inner side wall of the second fixing tube 14. There is a gap between the two bearings. The screw of the second bolt 12 is located between the two bearings. The rotation of the fixing column 13 is made smoother by the bearing.

[0030] Working principle:

[0031] During the use process, as Figure 4As shown, the patient lies prone on the bed according to the operation method of the existing HIFU surgery, and aligns the abdomen with the hole on the bed, then a first fixing plate 1 is arranged on both sides of the patient's waist, and the second fixing plate 4 is fixed to the bed through the groove body 7, and then the screw 5 is rotated to make the first fixing plate 1 approach the middle and contact the patient, and the patient is blocked by the two first fixing plates 1 to prevent the patient from moving left and right; in order to further limit the movement of the patient, the first fixing plates 1 are also arranged on both sides of the patient's legs, and then the second fixing plate 4 is fixed to the bed through the groove body 7, and then The screw 5 is rotated to make the first fixing plate 1 move toward the middle and contact the patient's legs to prevent the patient's legs from moving and better restrict the patient's movement. Of course, the patient's legs are provided with fixing columns 13 and second fixing tubes 14, which can rotate the second fixing plate 4 of the legs, thereby tilting the first fixing plate 1 at the leg position, so that the first fixing plate 1 fits better with the patient's legs and better restricts them. The patient is blocked by the first fixing plate 1 without forced restraint, thereby avoiding the patient's sense of restraint and effectively reducing the patient's discomfort.
