Description

Technical Field

[0001] This utility model relates to the field of medical equipment, and in particular to a lead apron weight reduction device. Background Technology

[0002] Interventional therapy is a minimally invasive treatment using modern high-tech methods. Guided by medical imaging equipment, specialized catheters, guidewires, and other precision instruments are introduced into the body to diagnose and treat internal conditions. Commonly used medical imaging equipment during the procedure includes digital subtraction angiography (DSA), CT, ultrasound, and MRI. Because some medical imaging equipment requires X-ray fluoroscopy, prolonged exposure to X-rays can cause radiation damage to medical personnel. Therefore, medical staff typically wear lead aprons during surgery. Common protective equipment consists of lead products such as lead aprons, lead pants, and lead caps. However, since lead materials weigh an average of about 20 kilograms, wearing heavy lead protective gear makes it difficult for medical staff to perform continuous surgical procedures. The forward-leaning posture also puts pressure on their spines, still posing a health hazard to medical personnel. Utility Model Content

[0003] The purpose of this invention is to design a lead apron weight reduction device to solve the above problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] Lead apron weight reduction equipment includes:

[0006] Mounting module; the lead apron is mounted on the mounting module;

[0007] First rotating arm;

[0008] Second rotating arm; the first end of the second rotating arm is rotatably mounted on the fixed surface, and the first end of the first rotating arm is rotatably mounted on the second end of the second rotating arm;

[0009] Wire rope;

[0010] Installation components; the first end of the steel wire rope passes through the installation components, wraps around the first end of the second rotating arm, the first end of the second rotating arm, and the first end of the first rotating arm, and is fixedly connected to the mounting module;

[0011] Storage roll; the second end of the steel wire rope is fixed to the storage roll;

[0012] Drive module; The drive module is used to drive the rotation of the storage roll;

[0013] Force sensor; a force sensor is used to collect the force on the first end of a steel wire rope;

[0014] Central controller; The central controller is used to control the operation of the drive module. The data output terminal of the force sensor is connected to the data input terminal of the central controller, and the control signal output terminal of the central controller is connected to the control signal input terminal of the drive module.

[0015] The beneficial effects of this utility model are as follows: the force applied to the lead apron by the mounting module reduces the pressure on the doctor. During use, the doctor needs to change posture and position according to the actual situation. The first and second rotating arms provide a range of motion perpendicular to the direction of gravity. The force sensor detects the force on the steel wire rope in real time. When the force is not within the preset threshold range, the central controller activates the drive module to raise or lower the first end of the steel wire rope. During the doctor's use, the lead apron weight reduction device reduces the pressure on the doctor while adapting to changes in the doctor's position and posture, improving the doctor's flexibility in using the lead apron.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the lead apron weight reduction device includes:

[0030] Mounting module 1; the lead apron is mounted on mounting module 1;

[0031] First rotating arm 2;

[0032] Second rotating arm 3; the first end of the second rotating arm 3 is rotatably mounted on the fixed surface, and the first end of the first rotating arm 2 is rotatably mounted on the second end of the second rotating arm 3;

[0033] 4 steel wire ropes;

[0034] Installation components; the first end of the steel wire rope 4 passes through the installation components, wraps around the first end of the second rotating arm 3, the first end of the second rotating arm 3 and the first end of the first rotating arm 2, and is fixedly connected to the mounting module 1;

[0035] Storage roll; the second end of steel wire rope 4 is fixed to the storage roll;

[0036] Drive module 7; Drive module 7 is used to drive the rotation of the storage roll;

[0037] Force sensor 8; Force sensor 8 is used to collect the force on the first end of the wire rope 4;

[0038] Central controller; The central controller is used to control the operation of drive module 7. The data output terminal of force sensor 8 is connected to the data input terminal of the central controller, and the control signal output terminal of the central controller is connected to the control signal input terminal of drive module 7. The model of force sensor is JLBM-M1, and the model of central controller is STM32F407.

[0039] The lead apron weight reduction device also includes a base bracket, the first end of the second rotating arm 3 is rotatably mounted on the base bracket, and the drive module 7 is mounted on the base bracket.

[0040] The lead apron weight reduction device also includes a linear motion component 9. The base support includes a base 10 and a mounting bracket 11. A slide rail 12 is provided on the base 10, and a slider 13 is fixed on the mounting bracket 11. The slider 13 is slidably installed in the slide rail 12 of the base 10. The moving end of the linear motion component 9 acts on the mounting bracket 11. The first end of the second rotating arm 3 is rotatably installed on the mounting bracket 11. The linear motion component 9 is installed on the base 10. By changing the height of the mounting bracket 11 through the linear motion component 9, the lead apron weight reduction device can adapt to the needs of different operating room heights. At the same time, a brakeable caster can be configured at the lower end of the base 10 to realize the movement of the overall position of the lead apron weight reduction device.

[0041] The mounting assembly includes a first guide wheel 14, a second guide wheel, and a third guide wheel 16. The first guide wheel 14 is rotatably mounted on the first end of the second rotating arm 3, the second guide wheel is rotatably mounted on the second end of the first rotating arm 2, and the third guide wheel 16 assembly is mounted on the second end of the second rotating arm 3. The central axis of the third guide wheel 16 assembly coincides with the rotation center of the first end of the first rotating arm 2. The steel wire rope 4 is wound around the first guide wheel 14 and the second guide wheel.

[0042] The third guide wheel 16 assembly includes a connecting frame 15 and two third guide wheels 16, both of which are rotatably mounted on the connecting frame 15. The wire rope 4 is located between the two third guide wheels 16, and the connecting frame 15 is mounted on the second end of the second rotating arm 3.

[0043] like Figure 4 As shown, the mounting bracket 11 is provided with a through hole 5, through which the wire rope 4 passes. The central axis of the through hole 5 coincides with the rotation center of the first end of the second rotating arm 3. Point A6 of the first guide wheel 14 is located on the central axis of the through hole 5. Point A6 is the contact point between the wire rope 4 and the first guide wheel 14. The tangent of the first guide wheel 14 at point A6 is parallel to the central axis of the through hole 5. The design of point A6 avoids friction between the mounting bracket 11 and the wire rope 4 during the rotation of the second rotating arm 3, and also avoids the wire rope 4 squeezing the side wall of the first guide wheel 14, and the friction between the wire rope 4 and the side wall of the first guide wheel 14 during the winding process of the wire rope 4 during the use of the lead apron.

[0044] The design of the first rotating arm 2 and the second rotating arm 3 not only gives the mounting module 1 a 360-degree degree of freedom of movement on the horizontal plane, but also avoids the torsional force on the wire rope 4 when it rotates with only one rotating arm or without a rotating arm.

[0045] The linear moving part 9 can be any one of a cylinder, a hydraulic cylinder, or a linear module.

[0046] The lead apron weight reduction device also includes an electromagnet. A connecting block is installed on the upper end of the lead apron. The connecting block can be magnetized. The electromagnet is installed on the mounting module 1. By controlling the on and off of the electromagnet, the connection and disconnection between the lead apron and the mounting module 1 can be quickly realized.

[0047] The working principle of this lead apron weight reduction device is as follows:

[0048] When the lead apron is worn on the human body, a threshold is set (e.g., 0.2KG). That is, if the lead apron weighs 11KG and the human body bears 0.2KG, the device provides an upward pulling force of 10.8KG. When the doctor performs actions such as bending over or squatting, the force sensor 8 will detect an increase in force. At this time, the central processing unit controls the drive module 7 to lower the first end of the steel wire rope 4 until the human body load is 0.2KG. Similarly, when the person goes from a squatting position to a standing position, the force sensor 8 will detect a decrease in force. The central processing unit controls the drive module 7 to raise the first end of the steel wire rope 4 until the human body load is 0.2KG. The force sensor 8 will continuously detect the load weight on the steel wire rope 4.

[0049] Before the doctor moves or puts on the lead apron, the first rotating arm 2 and the second rotating arm 3 can provide the mounting module 1 with a range of motion perpendicular to the direction of gravity, changing the position of the lead apron on the horizontal plane. This allows the lead apron weight reduction device to reduce the pressure on the doctor while adapting to changes in the doctor's position and posture, thus avoiding any obstruction to the doctor's use and improving the doctor's flexibility in using the lead apron.

[0050] The technical solution of this utility model is not limited to the specific embodiments described above. All technical modifications made based on the technical solution of this utility model shall fall within the protection scope of this utility model.
