Description

Technical Field

[0001] This invention relates to the field of urological surgery, and more specifically to a leg support device for use in urology. Background Technology

[0002] Urology is a branch of medicine that specializes in the study of the male and female urinary and reproductive systems. It is a subspecialty derived from surgery. The male urinary and reproductive systems are inseparable, while the female urinary tract opens into the external genitalia. Therefore, regardless of gender, the urinary and reproductive tracts are closely related, and diseases of both often affect each other. The organs covered by urology include the kidneys, ureters, bladder, urethra, as well as the testes, epididymis, vas deferens, seminal vesicles, prostate, scrotum, and penis of the male reproductive system. Urology also has close relationships with many other medical fields such as nephrology, obstetrics and gynecology, andrology, and oncology. In urological surgery, the lithotomy position is often used. The patient's lower legs are supported by a leg support frame, and the patient's legs are adjusted to a certain angle to fully expose the surgical field and facilitate better surgical operations. When supporting the patient's legs, medical staff need to install the leg support plate and leg support rod in sequence, and then lift the patient's legs onto the leg support frame one by one. This makes the operation complicated, time-consuming and labor-intensive, with low work efficiency and a great waste of the physical strength of medical staff. Based on this, the present invention provides a leg support device for urology to solve the problems mentioned in the background art. Summary of the Invention

[0018] refer to Figures 1 to 8 A leg support device for urology includes a bed board 1, a support leg 101, a mounting plate 102, a first leg support plate 2, and a second leg support plate 3. Four support legs 101 are installed under the bed board 1. The support legs 101 are used to install the bed board 1. Two mounting plates 102 are rotatably connected to the bed board 1. The bed board 1 is used to install the mounting plates 102. The first end of the first leg support plate 2 is hinged above the mounting plate 102. A rotating mechanism that drives the first leg support plate 2 to open and close is installed between the bed board 1 and the first leg support plate 2. A rotating mechanism that drives the first leg support plate 2 to rotate is installed between the mounting plate 102 and the first leg support plate 2. The rotating mechanism is driven by a rotation mechanism. The first leg support plate 2 is hinged to the second end of the second leg support plate 3. The second leg support plate 3 is equipped with a clamping mechanism for clamping the patient's lower leg. The clamping mechanism is driven by a rotating mechanism. A massage mechanism for massaging the patient's calves is installed on the second leg support plate 3 below the clamping mechanism. The massage mechanism is driven by the clamping mechanism. The rotating mechanism includes a drive component 21, a one-way threaded rod 22, a fixed plate 23, a first movable plate 24, a first gear 25, a first rotating shaft 26, an L-shaped plate 27, and a second rotating shaft 28. Two fixed plates 23 are respectively installed under the bed plate 1. The first movable plate 24 is slidably installed under the bed plate 1 between the two fixed plates 23. The one-way threaded rod 22 is threaded through the inner thread of the first movable plate 24. Both ends of the one-way threaded rod 22 are rotatably connected to the fixed plates 23 respectively. The fixed plate 23 is used to install the one-way threaded rod 22. One end of the one-way threaded rod 22 rotatably passes through one of the fixed plates 23 and is connected to the drive component 21. The drive component 21 is a rotating handle. An L-shaped plate 27 is vertically connected to the bed board 1 on the right side of the mounting plate 102. Racks are installed on both sides of the first moving plate 24. A first gear 25 is meshed with the outside of the rack. The first end of the first rotating shaft 26 is connected to the first gear 25. The second end of the first rotating shaft 26 rotates through the bed board 1 and is connected to the bottom of the mounting plate 102. The mounting plate 102 is connected to the first end of the second rotating shaft 28. The horizontal plate of the L-shaped plate 27 through which the second end of the second rotating shaft 28 rotates is hinged to the first end of the first leg support plate 2. The L-shaped plate 27 is used to mount the second rotating shaft 28. The first leg support plate 2 operates by rotating a rotating mechanism; Preferably, the driving component 21 drives the one-way threaded rod 22 to rotate, the rotation of the one-way threaded rod 22 moves the first moving plate 24, the movement of the first moving plate 24 drives the rack to move, the movement of the rack drives the first gear 25 to rotate, the rotation of the first gear 25 drives the first rotating shaft 26 to rotate, the rotation of the first rotating shaft 26 drives the mounting plate 102 to rotate, the rotation of the mounting plate 102 drives the first leg support plate 2 to rotate through the second rotating shaft 28, the rotation of the first leg support plate 2 is used to separate the patient's legs at a certain angle, so as to make the surgical field fully exposed; The rotating mechanism includes a second gear 29, a toothed plate 210, a sliding block 211, and a telescopic rod 212. The second gear 29 is rotatably mounted on the second rotating shaft 28 between the horizontal plate of the L-shaped plate 27 and the first end of the first leg support plate 2. The second gear 29 is connected to the horizontal plate of the L-shaped plate 27. The sliding block 211 is slidably mounted on the mounting plate 102 on the left side of the second gear 29. The first end of the telescopic rod 212 is connected to the sliding block 211. The second end of the telescopic rod 212 is vertically connected to the bottom of the second leg support plate 3. The telescopic rod 212 is used to facilitate the lifting and lowering of the second leg support plate 3 when the first leg support plate 2 rotates around the second rotating shaft 28. The second gear 29 is meshed with a toothed plate 210 on its inner side, and one end of the toothed plate 210 is connected to the sliding block 211. The first leg support plate 2 operates through a rotary drive clamping mechanism; Preferably, since the bed board 1 is vertically connected to the L-shaped plate 27, the second gear 29 is fixedly connected to the L-shaped plate 27, and thus the second gear 29 is fixed. The inner side of the second gear 29 is meshed with a toothed plate 210, and a sliding block 211 is slidably installed on the mounting plate 102. One end of the toothed plate 210 is connected to the sliding block 211, so that the mounting plate 102 rotates and drives the toothed plate 210 to move through the fixed second gear 29. The movement of the toothed plate 210 causes the sliding block 211 to move, and the movement of the sliding block 211 causes the telescopic rod 212 to move. The sliding block 211 and the telescopic rod 212 will not tilt during the movement, which causes the telescopic rod 212 to move and drive the second leg support plate 3 to move horizontally. Since the horizontal plate of the L-shaped plate 27 through which the second end of the second rotating shaft 28 rotates is hinged to the first end of the first leg support plate 2, the second leg support plate 3 moves horizontally, causing the first end of the first leg support plate 2 to rotate around the second rotating shaft 28, and then the second end of the first leg support plate 2 drives the second leg support plate 3 to move horizontally and rise and fall. This allows the second leg support plate 3 to move horizontally and rise and fall, and the first leg support plate 2 to rotate, thereby moving the patient's leg to the lithotomy position, fully exposing the surgical field, facilitating better subsequent surgical operations, and preventing the situation where medical staff need to install the leg support plate and leg support rod in sequence and lift the patient's leg onto the leg support frame in sequence when supporting the patient's leg, which makes the operation complicated, time-consuming, labor-intensive, and inefficient. The clamping mechanism includes a third gear 31, a third rotating shaft 32, a fourth gear 33, a bidirectional threaded rod 34, a protrusion 35, a clamping plate 36, and an air cushion 37. The first end of the third rotating shaft 32 is connected to the outer side of the second end of the first leg support plate 2, and the third gear 31 is fixedly sleeved on the second end of the third rotating shaft 32. The second leg support plate 3 is provided with a first sliding groove, in which two protrusions 35 are slidably installed. The two protrusions 35 are threaded through the same bidirectional threaded rod 34. One end of the bidirectional threaded rod 34 is rotatably inserted through the side wall of the first sliding groove and fixedly fitted with a fourth gear 33. The fourth gear 33 is meshed with the third gear 31. Specifically, the radius of the third gear 31 is larger than that of the fourth gear 33, so that when the third gear 31 rotates less than a quarter turn, it can drive the fourth gear 33 to rotate many turns. The top of the protrusion 35 slides through the first groove and is vertically connected to the clamping plate 36. An air cushion 37 is installed on the inner side of the clamping plate 36. The fourth gear 33 drives the massage mechanism to work by rotating; Preferably, the movement of the second leg support plate 3 causes the first leg support plate 2 to rotate around the second rotating shaft 28, resulting in relative rotation between the second leg support plate 3 and the first leg support plate 2. The outer side of the second end of the first leg support plate 2 is connected to the first end of the third rotating shaft 32. The second end of the third rotating shaft 32 is fixedly fitted with a third gear 31. The fourth gear 33 meshes with the third gear 31, thereby causing the fourth gear 33 to rotate. The rotation of the fourth gear 33 causes the bidirectional threaded rod 34 to rotate. The rotation of the bidirectional threaded rod 34 causes the protrusions 35 to move towards each other. The movement of the protrusions 35 towards each other causes the clamping plate 36 to move towards each other. The movement of the clamping plate 36 towards each other causes the air cushion 37 to move towards each other. The movement of the air cushion 37 towards each other is used to clamp and fix the patient's lower leg to prevent it from falling off during the operation and affecting the operation. The massage mechanism includes a rolling massage head 4, a sliding column 41, a lever 42, a first moving rod 43, a second moving rod 44, and a second moving plate 45. A groove is provided in the second leg support plate 3 between the two clamping plates 36. A lever 42 is installed on the outer side of the fourth gear 33. The lever 42 has a through second slide groove. A sliding column 41 is rotatably installed on the eccentric position of the fourth gear 33. The sliding column 41 is slidably connected in the second slide groove. The first end of the first moving rod 43 is vertically connected to the left side of the lever 42. The second leg support plate 3 on the inner side of the second end of the first moving rod 43 has a through groove and a third slide groove. The second moving rod 44 slides through the third slide groove. The first end of the second moving rod 44 is vertically connected to the second end of the first moving rod 43. The second end of the second moving rod 44 is connected to the second moving plate 45. The second moving plate 45 is slidably set in the groove. The top wall of the groove above the second moving plate 45 has two fourth slide grooves. Several rolling massage heads 4 are installed on the second moving plate 45. The several rolling massage heads 4 slide through the fourth slide grooves. Preferably, the rotation of the bidirectional threaded rod 34 drives the sliding column 41 to rotate, the rotation of the sliding column 41 drives the lever 42 to reciprocate, the reciprocating movement of the lever 42 drives the first moving rod 43 to reciprocate, the reciprocating movement of the first moving rod 43 drives the second moving rod 44 to reciprocate, the reciprocating movement of the second moving rod 44 drives the second moving plate 45 to reciprocate, the reciprocating movement of the second moving plate 45 drives the rolling massage head 4 to reciprocate. The reciprocating movement of the rolling massage head 4 is used to perform rolling massage on the patient's calves, preventing prolonged placement and causing leg soreness and discomfort, and increasing the practicality of the device. The mounting plate 102 is provided with a T-shaped groove, and the sliding block 211 is provided with a T-shaped protrusion 213 that cooperates with the T-shaped groove. The T-shaped protrusion 213 is slidably connected in the T-shaped groove. The cooperation between the T-shaped groove and the T-shaped protrusion 213 ensures that the sliding block 211 slides smoothly on the mounting plate 102.

[0019] The method of using this invention is as follows: When a patient needs to undergo urological surgery, the patient lies on a bed board with both legs horizontally placed on the first leg support plate 2 and the second leg support plate 3. Then, the operator rotates the drive component 21, which drives the one-way threaded rod 22 to rotate. The rotation of the one-way threaded rod 22 moves the first moving plate 24, which in turn moves the rack. The rack moves the first gear 25, which in turn moves the first rotating shaft 26. The rotation of the first rotating shaft 26 moves the mounting plate 102, which in turn drives the first leg support plate 2 to separate and rotate via the second rotating shaft 28. The separation and rotation of the first leg support plate 2 is used to separate the patient's legs at a certain angle, so that the surgical field can be fully exposed. Meanwhile, since the vertical plate of the L-shaped plate 27 is vertically connected to the bed board 1, and the second gear 29 is fixedly connected to the horizontal plate of the L-shaped plate 27, the second gear 29 is fixed and cannot be moved. The toothed plate 210 is meshed with the inner side of the second gear 29, and the sliding block 211 is slidably installed on the mounting plate 102. One end of the toothed plate 210 is connected to the sliding block 211, so that the mounting plate 102 rotates and drives the toothed plate 210 to move to the right through the fixed second gear 29. The toothed plate 210 moves to the right, causing the sliding block 211 to move to the right. The sliding block 211 moves to the right, causing the telescopic rod 212 to move to the right. The sliding block 211 and the telescopic rod 212 will not tilt during the movement, causing the telescopic rod 212 to move to the right, which in turn causes the second leg support plate 3 to move horizontally to the right. Because the horizontal plate of the L-shaped plate 27 through which the second end of the second rotating shaft 28 rotates is hinged to the first end of the first leg support plate 2, the second leg support plate 3 moves horizontally to the right, causing the first end of the first leg support plate 2 to rotate around the second rotating shaft 28, and then the second end of the first leg support plate 2 causes the second leg support plate 3 to move horizontally to the right and rise. This allows the second leg support plate 3 to move horizontally to the right and rise, and the first leg support plate 2 to rotate, thereby moving the patient's leg to the lithotomy position, fully exposing the surgical field, facilitating better subsequent surgical operations, and preventing the situation where medical staff need to install the leg support plates and leg support rods one by one when supporting the patient's leg, and the medical staff need to lift the patient's leg onto the leg support frame one by one, which makes the operation complicated, time-consuming and laborious, and inefficient. Simultaneously, as the second leg support plate 3 moves to the right, it causes the first leg support plate 2 to rotate around the second rotating shaft 28, resulting in relative rotation between the second leg support plate 3 and the first leg support plate 2. The outer side of the second end of the first leg support plate 2 is connected to the first end of the third rotating shaft 32. The second end of the third rotating shaft 32 is fixedly fitted with a third gear 31. The fourth gear 33 meshes with the third gear 31, thereby causing the fourth gear 33 to rotate. The rotation of the fourth gear 33 drives the bidirectional threaded rod 34 to rotate. The rotation of the bidirectional threaded rod 34 drives the protrusion 35 to move towards each other. The movement of the protrusion 35 towards each other drives the clamping plate 36 to move towards each other. The movement of the clamping plate 36 towards each other drives the air cushion 37 to move towards each other. The movement of the air cushion 37 towards each other is used to clamp and fix the patient's lower leg to prevent it from falling off during the operation and affecting the operation. After the surgery is completed, the staff rotates the drive component 21 in the opposite direction. At this time, the first leg support plate 2 and the second leg support plate 3 are reset, and the air cushion 37 moves away from each other to release the clamping on the patient's lower leg. Simultaneously, the rotation of the bidirectional threaded rod 34 drives the sliding column 41 to rotate, which in turn drives the lever 42 to move back and forth left and right. The reciprocating movement of the lever 42 drives the first moving rod 43 to move back and forth left and right, which in turn drives the second moving rod 44 to move back and forth left and right. The reciprocating movement of the second moving rod 44 drives the second moving plate 45 to move back and forth left and right, which in turn drives the rolling massage head 4 to move back and forth left and right. The reciprocating movement of the rolling massage head 4 is used to perform rolling massage on the patient's calves, preventing prolonged placement and causing leg soreness and discomfort, thus increasing the practicality of the device.

[0020] This invention, through the inclusion of a rotating mechanism, enables the separation and rotation of the first leg support plate to open the patient's leg at a certain angle, facilitating full exposure of the surgical field. Simultaneously, the rotating mechanism allows the second leg support plate to move to the right and rise, rotating in conjunction with the first leg support plate to move the patient's leg to the lithotomy position, further exposing the surgical field and facilitating subsequent surgical procedures. This avoids the cumbersome, time-consuming, and inefficient process of manually installing leg supports and lifting the patient's leg onto the support frame, which is required when supporting the patient's leg. Furthermore, the invention incorporates a clamping mechanism to achieve… The invention employs a first leg support plate that separates and rotates to separate the patient's legs at a certain angle, while the second leg support plate moves to the right and rises, simultaneously rotating the first leg support plate to move the patient's legs to the lithotomy position.

This invention has a simple and reliable structure, provides good leg support, is easy to control, and is suitable for widespread application.
