Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a portable lead clothing hanger and its method of use. Background Technology

[0002] During interventional radiology, cardiovascular intervention, and minimally invasive surgeries, medical personnel are required to wear lead aprons for radiation protection. Clinically, lead aprons typically weigh approximately 10 to 20 kilograms. During prolonged continuous surgeries, the entire weight of the lead apron is borne by the surgeon, continuously compressing the shoulders, lumbar spine, and knee joints. This can easily lead to occupational injuries such as lumbar muscle strain, lumbar spine injury, and knee pain. Over time, these injuries can seriously affect the health and surgical endurance of interventional surgeons.

[0003] Currently, there is a lack of support devices in clinical practice that can distribute the weight of the lead apron to the surgeon during surgery, forcing the surgeon to bear the full load of the lead apron throughout the procedure. To address this issue, there is an urgent need to design a portable lead apron frame that can effectively support the lead apron during surgery, transferring part of its weight to the frame, thereby significantly reducing the burden and damage to the lumbar spine, knee joints, and other areas of interventional surgeons caused by long-term wearing of lead aprons. Summary of the Invention

[0004] The purpose of this invention is to provide a portable lead clothing hanger and its method of use, so as to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by the present invention is as follows:

[0006] A portable lead garment rack includes a pair of connectors and a fixing member. The pair of connectors are hinged together and fixed together by the fixing member to form a closed space. Each pair of connectors includes a first arc-shaped fixing plate and a second arc-shaped fixing plate. The first arc-shaped fixing plate is positioned above the second arc-shaped fixing plate, and a pair of fixing rods connects the first and second arc-shaped fixing plates. A pair of support rods are connected to the bottom surface of the second arc-shaped fixing plate, and casters are installed at the bottom ends of the support rods. A sliding sleeve is installed on the inner side of one of the first arc-shaped fixing plates, and a sliding rod slides inside the sliding sleeve. Both the sliding sleeve and the sliding rod are vertically arranged. A clamping element is provided on the outer side of the sliding sleeve to fix the height of the sliding rod. A connecting block is installed at the top of the sliding rod, extending into the enclosed space. A clothes hanger is installed on the bottom surface of the connecting block. The first arc-shaped fixing plate, the second arc-shaped fixing plate, and the fixing rod cooperate with each other to form a stable load-bearing frame. The support rod and the casters cooperate with each other to allow the device to move in the operating room. The sliding sleeve, the sliding rod, and the clamping element cooperate with each other to allow the height of the clothes hanger to be changed according to the usage requirements. The clothes hanger and the connecting block cooperate with each other to support the weight of the lead apron, so that the weight of the lead apron is borne by the device, reducing the load on the doctor's body.

[0007] Furthermore, the clamping component includes a pipe clamp fitted around the outside of the sliding sleeve. The pipe clamp has a notch, and fixing blocks are installed at both ends of the notch. A cam handle is installed on the side of one of the fixing blocks. The shaft of the cam handle passes through the two fixing blocks and is threaded with a nut. The nut abuts against the side of the other fixing block. The pipe clamp, fixing blocks, and cam handle cooperate with each other to change the tightness of the pipe clamp on the sliding sleeve, so that the height of the sliding rod can be fixed or unfixed, ensuring that the position of the clothes hanger remains stable during use.

[0008] Furthermore, the surface of the sliding rod has a limiting groove opened along its axial direction, and the inside of the sliding sleeve is equipped with a limiting strip along its axial direction. The limiting strip slides in the limiting groove. The sliding sleeve and the sliding rod are arranged coaxially. The limiting groove on the sliding rod and the limiting strip inside the sliding sleeve cooperate with each other to restrict the sliding rod from rotating circumferentially during sliding, so that the sliding rod can only move in the vertical direction, ensuring that the clothes hanger will not deflect when supporting lead apron.

[0009] Furthermore, the two sides of the first arc-shaped fixing plates that are close to each other are hinged together. The hinge and the pair of first arc-shaped fixing plates cooperate with each other to enable the connector to open and close. Doctors can enter the closed space from the open position, which improves the ease of use of the device.

[0010] Furthermore, the fixing component includes a fixing sleeve installed on the inner side of one of the first arc-shaped fixing plates and a retaining sleeve installed on the inner side of the other first arc-shaped fixing plate. An L-shaped pin slides inside the fixing sleeve and can slide into the retaining sleeve. The fixing sleeve and the retaining sleeve are located near the other side of the pair of first arc-shaped fixing plates that are close to each other. The fixing sleeve, the retaining sleeve, and the L-shaped pin cooperate with each other to connect the two connecting components into a whole after closing, so that the device will not open on its own when supporting the weight of the lead apron and maintain the structural stability of the enclosed space.

[0011] Furthermore, a retaining ring is installed on the outer side of the L-shaped pin. The retaining ring can abut against the bottom end of the fixing sleeve. The L-shaped pin and the retaining ring cooperate with each other to limit the sliding range of the L-shaped pin in the fixing sleeve, prevent the L-shaped pin from completely detaching from the fixing sleeve, and ensure that the fixing structure can continue to function.

[0012] Furthermore, several uprights are installed on the top surface of each pair of the first arc-shaped fixing plates. An arc-shaped ring is installed at the top of each upright. The uprights and the arc-shaped rings cooperate with each other to form an auxiliary support structure, which can support the weight of the lead apron hem or side, making the weight distribution of the lead apron more uniform and improving the support effect of the device on the lead apron.

[0013] The present invention also aims to provide a method for using a portable lead clothing hanger, comprising the following steps:

[0014] S1. Move the device to the surgical position using the casters, rotate the hinge to open the pair of first arc-shaped fixing plates, and after the doctor enters the device, close and align the pair of first arc-shaped fixing plates, then slide the L-shaped pin into the sleeve to fix the pair of connectors and form a stable closed space.

[0015] S2. Adjust the height of the slide rod inside the sliding sleeve according to the doctor's height and surgical posture. After adjustment, turn the cam handle and lock the sliding sleeve with the tube clamp to fix the height of the slide rod.

[0016] S3. Hang the doctor's lead apron on the hanger at the shoulder. The hanger supports the weight of the lead apron, transferring the load to this device and reducing the pressure on the doctor's shoulders, lumbar spine and knee joints.

[0017] S4. Wrap the hem or side of the customized lead apron around the arc-shaped ring. The arc-shaped ring provides auxiliary support for the lead apron, further distributing its weight and improving stability and load reduction.

[0018] Compared with the prior art, the beneficial effects of this invention are as follows: In this mobile lead apron hanger, the casters allow the device to be moved to the surgical area to adapt to the needs of different surgical positions. The hinges, in conjunction with L-shaped pins and clips, allow the device to be quickly opened and closed, forming a closed space around the doctor without interfering with the surgical operation. The sliding sleeve and sliding rod, in conjunction with the clamping device, allow the height of the hanger to be adapted to doctors of different heights and surgical postures. The hanger supports the weight of the main body of the lead apron, while the uprights and arc-shaped rings support the weight of the hem and sides of the lead apron. The weight of the lead apron is transferred to the ground through the first arc-shaped fixing plate, the second arc-shaped fixing plate, the fixing rod, and the support rod. The doctor's shoulders, lumbar spine, and knee joints are no longer subjected to continuous pressure from the lead apron, which can reduce occupational injuries caused by wearing lead aprons for a long time, protect the doctor's health, prolong surgical endurance, and fill the gap in the clinical lack of intraoperative lead apron weight-relief support devices.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-4 This invention provides a technical solution: a portable lead garment rack, comprising a pair of connecting parts and a fixing part. The pair of connecting parts are hinged together and fixed together by the fixing part to form a closed space. Each pair of connecting parts includes a first arc-shaped fixing plate 1 and a second arc-shaped fixing plate 2. The first arc-shaped fixing plate 1 is positioned above the second arc-shaped fixing plate 2, and a pair of fixing rods 3 are connected between the first arc-shaped fixing plate 1 and the second arc-shaped fixing plate 2. A pair of support rods 11 are connected to the bottom surface of the second arc-shaped fixing plate 2, and universal wheels 4 are installed at the bottom ends of the support rods 11. A sliding sleeve 7 is installed on the inner side of one of the first arc-shaped fixing plates 1, and a sliding rod 8 slides inside the sliding sleeve 7. Both the sliding sleeve 7 and the sliding rod 8 are vertically arranged. A clamping part is provided on the outer side of the sliding sleeve 7 to fix the sliding rod. The sliding rod 8 has a height of 8. A connecting block 9 is installed at the top of the sliding rod 8. The connecting block 9 extends into the enclosed space. A clothes hanger 10 is installed on the bottom surface of the connecting block 9. The first arc-shaped fixing plate 1 and the second arc-shaped fixing plate 2 serve as the main structure of the connecting parts. The fixing rod 3 connects the first arc-shaped fixing plate 1 and the second arc-shaped fixing plate 2 to keep the upper structure stable. The support rod 11 supports the second arc-shaped fixing plate 2. The caster wheel 4 contacts the ground, allowing the device to move on the ground to the vicinity of the surgical area. The sliding rod 8 can move vertically inside the sliding sleeve 7 to change the height of the clothes hanger 10. The clamping element acts on the sliding sleeve 7 to keep the position of the sliding rod 8 fixed inside the sliding sleeve 7. The connecting block 9 extends the clothes hanger 10 into the enclosed space, allowing the clothes hanger 10 to contact the lead apron worn by the doctor and bear the weight.

[0026] As an embodiment of the present invention, the clamping member further includes a pipe clamp 12 sleeved on the outside of the sliding sleeve 7. The pipe clamp 12 has a notch, and fixing blocks 13 are installed at both ends of the notch. A cam handle 14 is installed on the side of one of the fixing blocks 13. The shaft of the cam handle 14 passes through the two fixing blocks 13 and is threaded with a nut. The nut abuts against the side of the other fixing block 13. The pipe clamp 12 wraps around the outside of the sliding sleeve 7. When the cam handle 14 rotates, it will drive the shaft to change the distance between the two fixing blocks 13. When the distance between the fixing blocks 13 decreases, the notch of the pipe clamp 12 becomes smaller, and the inner wall of the pipe clamp 12 is in close contact with the outer wall of the sliding sleeve 7. The sliding sleeve 7 deforms and holds the internal sliding rod 8 tightly. The sliding rod 8 can no longer slide. When the cam handle 14 rotates in the opposite direction, the distance between the fixing blocks 13 increases, the force of the pipe clamp 12 on the sliding sleeve 7 decreases, and the sliding rod 8 can slide freely inside the sliding sleeve 7.

[0027] As an embodiment of the present invention, the surface of the slide rod 8 has a limiting groove opened along its axial direction, and the inside of the slide sleeve 7 is equipped with a limiting strip along its axial direction. The limiting strip slides in the limiting groove. The slide sleeve 7 and the slide rod 8 are arranged coaxially. The limiting strip is located inside the limiting groove. When the slide rod 8 moves inside the slide sleeve 7, the limiting strip moves along the extension direction of the limiting groove. The limiting strip contacts the side wall of the limiting groove, preventing the slide rod 8 from rotating around its own axis, so that the slide rod 8 maintains directional stability during the lifting and lowering process, thereby ensuring that the clothes hanger 10 always maintains a suitable support angle.

[0028] As an embodiment of the present invention, the two first arc-shaped fixing plates 1 are further connected by a hinge on the side that is close to each other. The hinge connects the two first arc-shaped fixing plates 1, and the two first arc-shaped fixing plates 1 can rotate around the hinge. After rotation, an opening is formed between the two connecting parts, and the doctor can enter the device through the opening. After entering, the doctor rotates the first arc-shaped fixing plate 1 in the opposite direction to restore the device to the closed state.

[0029] As an embodiment of the present invention, the fixing member further includes a fixing sleeve 15 installed on the inner side of one of the first arc-shaped fixing plates 1 and a retaining sleeve 16 installed on the inner side of the other first arc-shaped fixing plate 1. An L-shaped pin 17 slides inside the fixing sleeve 15 and can slide into the retaining sleeve 16. The fixing sleeve 15 and the retaining sleeve 16 are close to each other on the other side between the pair of first arc-shaped fixing plates 1. After the two first arc-shaped fixing plates 1 are closed and aligned, the positions of the fixing sleeve 15 and the retaining sleeve 16 correspond. The L-shaped pin 17 moves inside the fixing sleeve 15 and one end of the L-shaped pin 17 enters the inside of the retaining sleeve 16. The fixing sleeve 15 and the retaining sleeve 16 are connected by the L-shaped pin 17, so that the two first arc-shaped fixing plates 1 cannot rotate relative to each other.

[0030] As an embodiment of the present invention, a retaining ring 18 is further installed on the outer side of the L-shaped pin 17. The retaining ring 18 can abut against the bottom end of the fixing sleeve 15. The retaining ring 18 moves together with the L-shaped pin 17. When the L-shaped pin 17 slides outward from the fixing sleeve 15, the retaining ring 18 gradually approaches the bottom end of the fixing sleeve 15. After the retaining ring 18 contacts the bottom end of the fixing sleeve 15, the L-shaped pin 17 can no longer move outward, thus preventing the L-shaped pin 17 from falling out of the fixing sleeve 15.

[0031] As an embodiment of the present invention, further, a plurality of uprights 5 are installed on the top surface of each pair of first arc-shaped fixing plates 1, and an arc-shaped ring 6 is installed at the top of the uprights 5. The uprights 5 are fixed on the first arc-shaped fixing plates 1 to support the arc-shaped ring 6. The arc-shaped ring 6 is located at the upper part of the device, and the hem or side of the lead apron can be placed on the arc-shaped ring 6. The arc-shaped ring 6 transfers this part of the weight to the first arc-shaped fixing plates 1 through the uprights 5, and then from the first arc-shaped fixing plates 1 to the lower support structure.

[0032] Please see Figures 1-4 The present invention also provides a technical solution: a method for using a portable lead clothing rack, comprising the following steps:

[0033] S1. Move the device to the surgical position using the casters 4, rotate the hinge to open the pair of first arc-shaped fixing plates 1, and after the doctor enters the device, close and align the pair of first arc-shaped fixing plates 1. Then slide the L-shaped pin 17 into the sleeve 16 to fix the pair of connectors and form a stable closed space.

[0034] S2. Adjust the height of the slide rod 8 inside the slide sleeve 7 according to the doctor's height and surgical posture. After adjustment, pull the cam handle 14 and lock the slide sleeve 7 through the tube clamp 12 to fix the height of the slide rod 8.

[0035] S3. Hang the lead apron worn by the doctor on the hanger 10. The hanger 10 supports the weight of the lead apron, transferring the load of the lead apron to this device and reducing the load and pressure on the doctor's shoulders, lumbar spine and knee joints.

[0036] S4. Wrap the hem or side of the customized lead apron around and drape it over the arc-shaped ring 6. The arc-shaped ring 6 provides auxiliary support for the lead apron, further distributing its weight and improving stability and load reduction.

[0037] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a control cabinet. The control circuit can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
