Description

Technical Field

[0001] This utility model relates to the field of medical device auxiliary equipment technology, specifically to an ultrasonic treatment head fixation device. Background Technology

[0002] A head immobilizer is typically fitted onto the patient's head, exposing the area requiring treatment and effectively securing it. After the patient is safely lying on the operating table or sitting in a treatment chair, the head immobilizer is fixed to the appropriate treatment area on the head. The treatment head utilizes ultrasound physical therapy to facilitate precise treatment of the head's target area.

[0003] Traditional ultrasound therapy requires the doctor to press the treatment head continuously throughout the procedure, ensuring it is in contact with the patient's head so that the liquid coupling agent can be delivered to the treatment area. Since treatments often last more than half an hour, this poses a significant challenge to the doctor's physical strength and hand stability. Prolonged manual pressing not only easily leads to doctor fatigue and increases the risk of human error, but also causes uneven force application, potentially leading to treatment head displacement and affecting energy transmission efficiency. Furthermore, it can cause the liquid coupling agent to leak from the gaps between the treatment head and the skin, contaminating the equipment or the patient's clothing.

[0004] Therefore, it is necessary to propose an ultrasonic treatment head fixation device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an ultrasonic treatment head fixing device. By adjusting the cooperation between the internal parts of the mechanism and the internal parts of the locking mechanism, the treatment head can be installed and fixed in the hollow cylinder, and the bottom end of the treatment head is pressed tightly against the treatment area of ​​the patient's head. This avoids fatigue caused by prolonged pressure by medical staff, and solves the problems in the prior art where prolonged manual pressing not only easily causes fatigue in doctors and increases the risk of human error, but also causes uneven force application, which can lead to treatment head displacement, affecting energy transmission efficiency, and allows liquid coupling agent to easily overflow from the gap between the treatment head and the skin, contaminating the equipment or the patient's clothing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic treatment head fixing device, including a treatment helmet, a hollow cylinder machined on one side of the top of the treatment helmet, an adjustment mechanism integrally formed at one end of the hollow cylinder and located at the top of the hollow cylinder, a locking mechanism threadedly connected to the top of the adjustment mechanism and extending through to the inner wall of the hollow cylinder, and a counterweight component threadedly connected to the top of the treatment helmet and located on one side of the diagonal of the hollow cylinder;

[0007] The adjustment mechanism includes a fixed rod integrally formed at one end of a hollow cylinder. An adjustment rod is connected to the top end of the fixed rod. A threaded post is machined at the bottom end of the adjustment rod and extends through the interior of the fixed rod. A crossbar is integrally formed at the top end of the adjustment rod and is located directly above the hollow cylinder.

[0008] The locking mechanism includes a long screw, which is connected to the top of the crossbar by a thread and extends to the bottom of the crossbar. A disc support plate is threaded to the bottom of the long screw. A treatment head is slidably connected to the inner wall of the hollow cylinder and is located below the disc support plate and fits against the bottom of the disc support plate.

[0009] The counterweight component includes a connecting rod, the bottom end of which is connected to the outer wall of the treatment helmet, and the top end of which has a counterweight block.

[0010] Preferably, the top end of the fixing rod is provided with a threaded hole that matches the threaded post, and the outer walls of the rod are connected with positioning pins. The outer walls of the threaded post are provided with positioning holes that match the positioning pins.

[0011] Preferably, the adjusting rod and the crossbar form an L-shaped structure, and the height between the crossbar and the hollow cylinder is more than 20 mm, and the fixing rod is level with the hollow cylinder.

[0012] Preferably, the crossbar has an adjustment hole on its surface directly above the hollow cylinder that matches the long screw, and the inner wall of the adjustment hole has an internal thread that matches the thread on the outer wall of the long screw. The top of the disc support plate has a connection hole that matches the thread on the outer wall of the long screw.

[0013] Preferably, one side of the outer wall of the hollow cylinder has a power line guide notch with a depth of three-quarters of the hollow cylinder, and the other side has an operation notch with a depth consistent with the length of the hollow cylinder. The treatment head, the disc support plate, and the long screw are located on a unified axis inside the hollow cylinder.

[0014] Preferably, the threads connecting the outer wall of the long screw to the crossbar and the threads connecting the bottom outer wall of the long screw to the disc support plate are in opposite directions, and the connecting rod and the hollow cylinder are diagonally distributed.

[0015] The present invention provides the following technical effects and advantages in the above-described technical solution;

[0016] 1. By aligning the adjusting rod with the fixed rod and threading the threaded column through the fixed rod, the connection and fixation between the fixed rod and the adjusting rod are completed. The top of the fixed rod has a threaded hole that matches the threaded column, and the outer walls of the fixed rod are connected with positioning pins. The outer walls of the threaded column have positioning holes that match the positioning pins. This allows the threaded column to be connected to the fixed rod through the thread, and the positioning pins to limit the connection between the threaded column and the fixed rod. The adjusting rod and the crossbar form an L-shaped structure, and the height between the crossbar and the hollow cylinder is more than 20mm, so that there is an adjustment space between the crossbar and the hollow cylinder to facilitate the installation of the treatment head.

[0017] 2. By placing the treatment head on the inner wall of the hollow cylinder, and through a power cord guide notch three-quarters the depth of the hollow cylinder on one side of the outer wall, and an operation notch with the same depth as the length of the hollow cylinder on the other side, medical staff can easily adjust the installation position of the treatment head inside the hollow cylinder. Rotating the long screw allows it to slide on the crossbar through the thread. Then, rotating the disc support plate, which is fixed to the bottom end of the long screw through the thread, and the disc support plate fits against the top of the treatment head, allows the long screw to rotate and slide on the crossbar, causing the disc support plate to press against the treatment head. This allows the treatment head to slide and extend inside the hollow cylinder under the pressure of the disc support plate, thus pressing the treatment head and ensuring a close fit between the treatment head and the patient's head treatment area.

[0018] 3. By placing the treatment head inside the hollow cylinder and fixing it in place, the treatment head is made to fit closely to the treatment area of ​​the patient's head. The design incorporates connecting rods attached to the treatment helmet and a counterweight at its top. Because the connecting rods and the hollow cylinder are diagonally symmetrically distributed, the center of gravity of the treatment helmet can be balanced during use, improving its stability.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-4 An ultrasonic treatment head fixation device is shown, including a treatment helmet 1. A hollow cylinder 101 is machined on one side of the top of the treatment helmet 1. An adjustment mechanism 2 is integrally formed at one end of the hollow cylinder 101 and is located at the top of the hollow cylinder 101. A locking mechanism 3 is threaded to the top of the adjustment mechanism 2 and extends through to the inner wall of the hollow cylinder 101. A counterweight 4 is connected to the top of the treatment helmet 1 and is located on one side of the diagonal of the hollow cylinder 101.

[0028] The adjustment mechanism 2 includes a fixed rod 201, which is integrally formed on one end of the hollow cylinder 101. An adjustment rod 202 is connected to the top end of the fixed rod 201. A threaded post 203 is machined at the bottom end of the adjustment rod 202 and extends through the interior of the fixed rod 201. A crossbar 204 is integrally formed at the top end of the adjustment rod 202 and is located directly above the hollow cylinder 101.

[0029] The locking mechanism 3 includes a long screw 30l, which is connected to the top end of the crossbar 204 by a thread and extends to the bottom end of the crossbar 204. The bottom end of the long screw 30l is threadedly connected to a disc support plate 302. The inner wall of the hollow cylinder 10l is slidably connected to a treatment head 303, which is located below the disc support plate 302 and fits against the bottom end of the disc support plate 302.

[0030] The counterweight component 4 includes a connecting rod 40l, the bottom end of which is connected to the outer wall of the treatment helmet 1, and a counterweight block 402 at the top end of the connecting rod 40l.

[0031] By adjusting the internal parts of the adjustment mechanism 2 and the internal parts of the locking mechanism 3, the treatment head 303 can be installed and fixed in the hollow cylinder 10l, and the bottom end of the treatment head 303 can be pressed tightly against the treatment area of ​​the patient's head, thereby avoiding fatigue caused by prolonged pressure by medical staff. Through the cooperation of the internal parts of the counterweight component 4, the center of gravity of the treatment helmet 1 can be balanced during use, thus improving the stability of the treatment helmet 1 during use.

[0032] Refer to the instruction manual appendix Figure 1-4 The top of the fixing rod 20l is provided with a threaded hole that matches the threaded post 203, and the outer walls of the fixing rod 20l are connected with positioning pins on both sides. The outer walls of the threaded post 203 are provided with positioning holes that match the positioning pins. The threaded post 203 is connected to the fixing rod 20l by threads, and the positioning pins are connected to the outer walls of the fixing rod 20l. This allows the threaded post 203 to be connected to the fixing rod 20l by threads, and the positioning pins are used to complete the connection and limit between the threaded post 203 and the fixing rod 20l.

[0033] Refer to the instruction manual appendix Figure 1-4 The adjusting rod 202 and the crossbar 204 form an L-shaped structure, and the height between the crossbar 204 and the hollow cylinder 10l is more than 20mm. The fixed rod 20l is level with the hollow cylinder 10l. The adjusting rod 202 and the crossbar 204 form an L-shaped structure, and the height between the crossbar 204 and the hollow cylinder 10l is more than 20mm, so that there is an adjustment space between the crossbar 204 and the hollow cylinder 10l to facilitate the installation of the treatment head 303.

[0034] Refer to the instruction manual appendix Figure 1-4 The crossbar 204 has an adjustment hole on its surface directly above the hollow cylinder 10l that matches the long screw 30l. The inner wall of the adjustment hole has an internal thread that matches the thread on the outer wall of the long screw 30l. The top of the disc support plate 302 has a connection hole that matches the thread on the outer wall of the long screw 30l. The adjustment hole on the crossbar 204 directly above the hollow cylinder 10l that matches the long screw 30l, and the internal thread on the inner wall of the adjustment hole that matches the thread on the outer wall of the long screw 30l, facilitates the extension and retraction adjustment of the long screw 30l on the crossbar 204 through the thread.

[0035] Refer to the instruction manual appendix Figure 1-4The hollow cylinder 10l has a power cord guide notch on one side of its outer wall, with a depth of three-quarters of the cylinder's length, and an operation notch on the other side, with a depth equal to the length of the cylinder. The treatment head 303, the disc support plate 302, and the long screw 30l are all located on a unified axis inside the hollow cylinder 10l. This arrangement facilitates medical personnel in adjusting the installation position of the treatment head 303 inside the hollow cylinder 10l and allows the disc support plate 302 to press and fix the treatment head 303 inside the hollow cylinder 10l.

[0036] Refer to the instruction manual appendix Figure 1-4 The threads connecting the outer wall of the long screw 30l to the crossbar 204 and the threads connecting the bottom outer wall of the long screw 30l to the disc support plate 302 are opposite in direction. The connecting rod 40l and the hollow cylinder 10l are diagonally distributed. The threads connecting the outer wall of the long screw 30l to the crossbar 204 and the threads connecting the bottom outer wall of the long screw 30l to the disc support plate 302 are opposite in direction. This makes it easier for the bottom end of the disc support plate 302 to fit against the top end of the treatment head 303 when the long screw 30l rotates and drives the disc support plate 302 to move downward. This also makes the disc support plate 302 more tightly connected to the bottom end of the long screw 301 through the reverse threads.

[0037] The working principle of this practical application is as follows:

[0038] Refer to the instruction manual appendix Figure 1-4 By aligning the adjusting rod 202 with the fixed rod 201 and threaded through the threaded column 203 into the fixed rod 201, the connection and fixation between the fixed rod 201 and the adjusting rod 202 are completed. The top of the fixed rod 201 has a threaded hole that matches the threaded column 203, and the outer walls of the fixed rod 201 are connected with positioning pins. The outer walls of the threaded column 203 have positioning holes that match the positioning pins. This allows the threaded column 203 to be connected to the fixed rod 201 by the thread, and the positioning pins to limit the connection between the threaded column 203 and the fixed rod 201. The adjusting rod 202 and the crossbar 204 form an L-shaped structure, and the height between the crossbar 204 and the hollow cylinder 101 is more than 20 mm, so that there is an adjustment space between the crossbar 204 and the hollow cylinder 101 to facilitate the installation of the treatment head 303.

[0039] Refer to the instruction manual appendix Figure 1-4By placing the treatment head 303 on the inner wall of the hollow cylinder 101, and by providing a power cord guide notch with a depth of three-quarters of the cylinder's length on one side of the outer wall of the hollow cylinder 101, and an operation notch with a depth equal to the length of the hollow cylinder 101 on the other side, medical personnel can easily adjust the installation position of the treatment head 303 inside the hollow cylinder 101. Rotating the long screw 301 allows for sliding connection on the crossbar 204 via the thread. Then, rotating the disc support plate 302... The support plate 302 is connected and fixed to the bottom end of the long screw 301 by threads, and the disc support plate 302 is in contact with the top of the treatment head 303. By rotating the long screw 301, the long screw 301 rotates and slides on the crossbar 204, causing the disc support plate 302 to squeeze the treatment head 303. Under the pressure of the disc support plate 302, the treatment head 303 slides and extends inside the hollow cylinder 101, thus completing the pressing of the treatment head 303 and making the treatment head 303 fit tightly with the treatment area of ​​the patient's head.

[0040] Reference manual attached Figure 1-4 By placing the treatment head 303 inside the hollow cylinder 101 and fixing it in place, the treatment head 303 is made to fit tightly against the treatment area of ​​the patient's head. A connecting rod 401 is designed and installed to connect with the treatment helmet 1, and the counterweight 402 on the connecting rod 401 is installed and fixed at the top of the treatment helmet 1, and is symmetrically distributed diagonally with the hollow cylinder 101. This balances the center of gravity of the treatment helmet 1 during use, improving its stability.
