DETAILED DESCRIPTION

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 4 As shown, an ultrasound probe fixing device can be applied to in vitro fertilization embryo transfer surgery. The specific structure includes a support rail 29, a sliding rod 20, a rotating lock 14, a telescopic rod 19, and a support rod 7. One end of the sliding rod 20 is slidably connected to the support rail 29, and the other end extends vertically downwards and is fitted with a storage rod 15; the rotating lock 14 is installed on the storage rod 15; the telescopic rod 19 passes through the rotating lock 14 and extends into the storage rod 15; the rotating lock 14 is used to adjust the tightness of the connection between the telescopic rod 19 and the storage rod 15; one end of the support rod 7 is connected to the telescopic rod 19, and the other end extends outwards and is slidably connected to the probe clamp.

[0028] The probe holder and the support rod 7 are connected by an adjustable sliding connection, which can realize both sliding and fixed connections. When it is necessary to slide the probe holder, adjust the probe holder to the sliding state, and then push the probe holder to slide along the length of the support rod. When it slides to the desired position, adjust the probe holder to the fixed state, and the probe holder is fixed on the support rod.

[0029] It should be noted that the rotary lock can be a commercially available telescopic rod positioner. Loosening the rotary lock allows the telescopic rod 19 to be retracted inwards and extended outwards relative to the storage rod 16.

[0030] Understandably, the telescopic rod and rotating lock can be used together to facilitate the use of the probe holder to hold the ultrasound probe by patients of different body sizes.

[0031] It should also be noted that the support rail 29 is installed on the ceiling of the ward. It can be perpendicular or parallel to the bed installed in the ward. The support rail can extend to the wall. When the probe holder is not in use, the sliding rod drives the support rod and the probe holder to move to the wall, reducing the obstruction of the sliding rod, support rod and probe holder to the daily work of medical staff.

[0032] In some alternative embodiments, a structure is provided for the probe holder and the sliding between the probe holder and the support rod.

[0033] A groove 71 is formed along the length of the support rod 7.

[0034] like Figures 1-3As shown, the probe clamping component includes a first limiting plate 9, a second limiting plate 10, a clamping seat 1, a movable plate 2, an adjusting screw 4, and an extension rod 6. The second limiting plate 10 is fitted with a limiting screw 8, which passes through a slide groove 71, the first limiting plate 9, and is threadedly connected to an adjusting nut 32. The clamping seat 1 has a clamping opening 101. The movable plate 2 is movably positioned within the clamping opening 101. The adjusting screw 4 passes through the clamping seat 1 and is rotatably connected to the movable plate 2, while the adjusting screw 4 is threadedly connected to the clamping seat 1. One end of the extension rod 6 is connected to the clamping seat 1, and the other end is connected to the first limiting plate 9.

[0035] The extension rod 6 allows for a larger gap between the clamping seat 1 and the support rod 7, which facilitates the clamping and fixing of the ultrasound probe.

[0036] Understandably, the limiting screw 8 passes through the slide groove 71, causing the first limiting plate 9 and the second limiting plate 10 to be suspended on the support rod.

[0037] like Figure 1 , 2 As shown, the first limiting plate 9 and the second limiting plate 10 are located on both sides of the support rod 7, forming a clamping support rod.

[0038] It should be noted that when the adjusting nut 32 is loosened, the first limiting plate 9 can rotate relative to the limiting screw 8. The first limiting plate can drive the extension rod to swing relative to the support rod, and the extension rod can drive the clamping seat to swing. The clamping seat can drive the ultrasound probe to tilt. When the adjusting nut 32 is tightened, the ultrasound probe on the clamping seat is in a fixed tilted state.

[0039] The probe holder slides relative to the support rod: Loosen the adjusting nut 32 to release the clamping of the support rod between the first limiting plate 9 and the second limiting plate 10, and push the extension rod 6 to push the probe holder to slide relative to the support rod.

[0040] The probe holder is fixed to the support rod: Tighten the adjusting nut 32. While the adjusting nut 32 moves closer to the support rod 7 along the limiting screw 8, it presses the first limiting plate 9 against the support rod 7. The limiting screw 8 pulls the second limiting plate 10 against the support rod 7. When the adjusting nut 32 is tightened, the first limiting plate 9 and the second limiting plate 10 clamp the support rod, and the probe holder is fixed on the support rod.

[0041] How the probe holder holds the ultrasound probe:

[0042] Twist the adjusting screw 4, so that the adjusting screw 4 extends outward relative to the clamping seat 1 while the adjusting screw 4 pulls the movable plate 2 close to one side of the clamping seat 1, and the distance between the other side of the clamping seat gradually increases. When the distance is appropriate for placing the B-ultrasound probe, the medical staff places the B-ultrasound probe into the space between the movable plate and the clamping seat, and then twists the adjusting screw 4 again. The adjusting screw 4 is screwed into the clamping seat and pushes the movable plate 2 to move towards the B-ultrasound probe. When the movable plate and the clamping seat fix the B-ultrasound probe, stop twisting the adjusting screw. The medical staff's hand can be separated from the B-ultrasound probe, and the B-ultrasound probe is clamped and fixed on the clamping seat.

[0043] When the B-ultrasound probe needs to be removed, twist the adjusting screw 4, and the adjusting screw 4 extends outward relative to the clamping seat. The adjusting screw pulls the movable plate away from the B-ultrasound probe, so that the movable plate and the clamping seat release the B-ultrasound probe.

[0044] In some optional embodiments, in order to further prevent the adjusting screw from loosening, a lock nut 3 is installed. The lock nut 3 is installed on the clamping seat 1, and the adjusting screw 4 passes through the lock nut 3 and the clamping seat 1.

[0045] The lock nut can further limit the adjusting screw, so that the adjusting screw is more stably installed on the clamping seat. It can also more stably support the movable plate in the clamping opening of the clamping seat.

[0046] In order to facilitate the twisting of the adjusting screw, an adjusting cap 5 is installed. The adjusting screw 4 is installed with the adjusting cap 5.

[0047] The medical staff holds the adjusting cap 5 and twists it clockwise. The adjusting cap drives the adjusting screw to rotate clockwise. Twist the adjusting cap counterclockwise, and the adjusting cap drives the adjusting screw to rotate counterclockwise.

[0048] In some optional embodiments, a fixing method of the sliding rod is given. A bottom rod 21, a bottom plate 22, an electric push rod 23 with a piston rod 231, a support plate 24, a pressure sensor 25, a guard plate 26 and a controller 31 are installed. One end of the bottom rod 21 is connected with the sliding rod 20, and the other end extends outward and is connected with the bottom plate 22. The electric push rod 23 is installed on the bottom plate 22. The piston rod 231 is connected with the support plate 24. The pressure sensor 25 is installed on the support plate 24. The top of the pressure sensor 25 is installed with the guard plate 26. The electric push rod 23 and the pressure sensor 25 are electrically connected with the controller 31.

[0049] When the piston rod 231 drives the support plate, the pressure sensor and the guard plate to move towards the ceiling, the pressure sensor is extruded on the ceiling through the guard plate, which can avoid direct extrusion of the pressure sensor on the ceiling and has a protective effect on the pressure sensor.

[0050] The pressure sensor and the controller interact in real time. The upper limit value of the pressure sensor 25 can be set on the controller 31. When the electric push rod 23 drives the piston rod 231 to lift upward, the pressure sensor 25 and the guard plate 26 of the support plate 24 are pressed against the ceiling of the patient room. As the pressure increases, when the pressure value monitored by the pressure sensor is equal to the set upper limit value, the controller controls the electric push rod 23 to stop driving the piston rod, so as to fix the sliding rod 20.

[0051] When the piston rod is pressed against the ceiling to release the pressure sensor, the electric push rod is controlled by the controller to retract the piston rod downward. The piston rod retracts downward, driving the support plate, the pressure sensor and the guard plate to move downward and away from the ceiling, releasing the fixed state of the sliding rod, and the sliding rod can move along the support rail.

[0052] It can be understood that the controller is provided with a stop button, an upward button and a downward button. The stop button can control the electric push rod to stop working. The upward button can control the electric push rod to work and drive the piston rod to lift upward. The downward button can control the electric push rod to work and drive the piston rod to retract and reset.

[0053] In some optional embodiments, a connecting structure of the telescopic rod and the support rod is given, and the fixed plate 18, the support screw 12 and the nut 11 are installed. The fixed plate 18 is installed on the telescopic rod 19, one end of the support screw 12 is installed on the fixed plate 18, and the other end penetrates the support rod 7 and is threadedly connected with the nut 11.

[0054] The support rod is installed on the fixed plate 18 through the support screw 12 and the nut 11, so that the support rod can be detachably installed relative to the fixed plate.

[0055] It can be understood that the support rod is provided with a mounting hole corresponding to the support screw, and the support screw is inserted into the mounting hole and threadedly connected with the nut.

[0056] During installation, the mounting hole on the support rod is sleeved on the support screw, the support rod is adjusted to a horizontal state (of course, it is not limited to a horizontal state), and the nut 11 is tightened to press and fix the support rod on the fixed plate.

[0057] During disassembly, the nut 11 is loosened, and the nut is detached from the support screw, so that the support rod and the support screw can be separated, and the support rod can be disassembled.

[0058] In some optional embodiments, a structure for limiting rotation of the support rod is given, and a rotation prevention rod 13 is installed. Figure 1 , 2 As shown in the drawings, the rotation prevention rod 13 is installed on the fixed plate 18, and the support rod 7 is provided with a through hole 30 corresponding to the rotation prevention rod 13; wherein when the rotation prevention rod 13 penetrates the through hole 30, the rotation of the support rod 7 is limited.

[0059] Understandably, the combination of the support screw and the anti-rotation rod can prevent the support rod from rotating.

[0060] In some alternative embodiments, a base 28 and stiffening plates 27 are added. For example... Figure 1 , 2 As shown, the base 28 has a rectangular structure along the length of the support slide rail 29 and is slidably connected to the support slide rail 29 to support the installation of the sliding rod 20. At least one stiffening plate 27 is installed between the sliding rod 20 and the base 28.

[0061] The base extends along the length of the support rail, increasing the contact area with the support rail. When force is applied to the sliding rod, the sliding rod can easily push the base to move along the support rail.

[0062] The number of stiffening plates 27 installed between the sliding rod 20 and the base 28 can be 1, 2, 3, or 4. The stiffening plates help improve the connection stability between the sliding rod and the base.

[0063] In some alternative embodiments, a sliding connection structure is provided for supporting the slide rail and the base. For example... Figure 1 As shown, a dovetail groove 291 is provided on the support slide rail 29 along the length direction, and a tail wing (not shown in the figure) is provided on the base 28 along the length direction. The tail wing is slidably connected to the dovetail groove 291.

[0064] The base and the support rail are connected by a dovetail joint, which facilitates the suspension of the base on the support rail. The dovetail joint also helps guide the base to slide.

[0065] The working principle of this utility model is as follows:

[0066] Medical staff hold the sliding rod 20 and slide it along the support rail 29 to the vicinity of the bed. The ultrasound probe is clamped on the clamping seat 1 of the probe holder, and the ultrasound probe is fixed to the clamping seat 1 by the movable plate 2. Adjusting the rotating lock 14 allows the telescopic rod 19 to move up and down. The telescopic rod 19 drives the support rod 7 and the probe holder to move, and the probe holder drives the ultrasound probe to move. During this process, the telescopic rod 19 can be rotated, causing the support rod and the probe holder to rotate accordingly. The probe holder can slide adjustablely along the support rod, which makes it easy to fit the ultrasound probe on the probe holder to the required position on the patient's abdomen.

[0067] Then, the rotary lock 14 is adjusted again so that the rotary lock 14 locks the telescopic rod 19 fixed on the storage rod 15, the position of the support rod 7 is fixed, the support rod 7 supports the probe holder, and the probe holder is adjustably slid with the support rod 7 through the first limiting plate 9, the second limiting plate 10, the limiting screw 8 and the adjusting nut 32; at this time, the adjusting nut 32 is tightened, the first limiting plate 9 and the second limiting plate 10 are clamped and fixed on the support rod 7, and the clamp seat 1 and the movable plate 2 are clamped and fixed through the supporting action of the adjusting screw 4 to clamp the B-ultrasound probe.

[0068] Subsequently, the electric push rod 23 is controlled to work through the controller 31, the electric push rod 23 drives the piston rod 231 to lift upward, the guard plate 26 moves upward to abut against the ceiling of the patient room, when the pressure value monitored by the pressure sensor 25 is equal to the set upper limit value of the pressure, data information is sent to the controller, the controller receives the data information and then controls the electric push rod to stop working, the piston rod 231 stops lifting, the supporting plate 24 is supported, the supporting plate 24 supports the pressure sensor and the guard plate to keep extruding on the ceiling, the fixed sliding rod 20 is achieved, and movement of the sliding rod 20 caused by external force is prevented. The B-ultrasound probe can be effectively fixed on the abdomen of the patient.

[0069] The above-mentioned embodiments are preferred embodiments of the present application, which are only used to facilitate the description of the present application and do not limit the present application in any form. Any person skilled in the art can make partial changes or modifications to equivalent embodiments within the scope of the technical features of the present application without departing from the technical features of the present application, and the equivalent embodiments still belong to the scope of the technical features of the present application.
