Description

Technical Field

[0001] The present invention belongs to the technical field of medical care, and specifically relates to a hemostatic compression device for medical care. Background Art

[0002] Pressing to stop bleeding is relatively easy for most patients. However, for critically ill patients or those who are unable to take care of themselves, they cannot complete the above pressing process by themselves. This requires medical staff to press the puncture point for a long time. During the pressing process on patients, due to improper pressing force or short pressing time of personnel, it is easy to cause subcutaneous congestion or bleeding on the skin. This undoubtedly increases the burden on medical staff and causes certain harm to patients. Therefore, a hemostatic compression device is often used to stop bleeding.

[0003] Chinese Utility Model CN216317793U discloses a compression hemostasis device for cardiology care, belonging to the technical field of cardiology care. It includes a fixed frame. A support rod is fixedly arranged on the upper surface of the fixed frame. A connecting block is fixedly arranged at the upper end of the support rod. A fixed column is fixedly arranged at one end of the connecting block. A moving column is slidably arranged in the fixed column. A limiting block is fixedly arranged at the end of the moving column away from the fixed column. A moving block is slidably arranged in the limiting block. A buffer mechanism is arranged at the lower end of the moving block; by holding the pull rod and pulling it upward, the pull rod drives the limiting plate upward, and then the hemostatic gauze wraps the hemostatic plate. After releasing the pull rod, the limiting plate is pressed against the hemostatic plate by the thrust of the second spring to fix the position of the hemostatic gauze. The first spring is used for buffering to prevent damage to the wound caused by excessive pressure.

[0004] However, when this hemostatic device is in use, the position of the hemostatic plate cannot be adjusted arbitrarily, which is not convenient to adjust the hemostatic plate directly above the hemostatic area, affecting the hemostatic effect. Summary of the Invention

[0043] The beneficial effects of the present invention are as follows:

[0044] 1. In the present invention, the connecting component is made into a flexible mechanism by the first locking component, the mounting seat is moved to the hemostatic site, so that the hemostatic cotton sheet under the conveyor belt is directly opposite to the hemostatic site. Then, the connecting component is made into a rigid mechanism by the first locking component to fix the position of the connecting seat. The second transmission component moves the sliding seat to the side away from the connecting seat, so that the mounting seat and the conveyor belt move towards the hemostatic site, and the hemostatic cotton sheet under the conveyor belt abuts against the hemostatic site. After the pressure of the hemostatic cotton sheet on the hemostatic site meets the requirements, the rotation of the shaft of the first motor stops, so that the hemostatic cotton sheet presses on the hemostatic site to perform compressive hemostasis on the hemostatic site. When the conveyor belt drives the hemostatic cotton sheet to move, the hemostatic cotton sheet has already separated from the hemostatic site, preventing the hemostatic cotton sheet from rubbing against the hemostatic site and preventing the friction from aggravating bleeding, thus ensuring the hemostatic effect. Before and after the replacement of the hemostatic cotton sheet, the sliding seat remains stationary, and the distance between the mounting seat and the sliding seat remains unchanged. Therefore, the pressure on the hemostatic site before and after the replacement of the hemostatic cotton sheet is consistent, ensuring the hemostatic effect.

[0045] 2. In the present invention, the distal arc surface of the swing member rotates downward to the side. Under the action of the elastic force of the first elastic member, the connecting plate moves upward, and the mounting seat moves upward. During this process, the gear structure of the first gear does not mesh with the second gear, and the conveyor belt does not move until the swing member swings to the horizontal state and the mounting seat stops moving. At this time, the gear structure of the first gear begins to mesh with the second gear, the first connecting shaft drives the swing member to continue to rotate, drives the second gear to rotate, drives the conveyor belt to move, and drives the hemostatic cotton sheet to move. When the swing member rotates to the horizontal state again, the gear structure of the first gear does not mesh with the second gear, so that the conveyor belt remains stationary. The first connecting shaft drives the swing member to continue to rotate, so that the distal arc surface of the swing member abuts against the lower end surface of the sliding seat again, and the mounting seat moves downward until the swing member rotates to the vertical state again. At this time, the distance between the mounting seat and the sliding seat is the largest, and the hemostatic cotton sheet abuts against the hemostatic site again to complete the replacement of the hemostatic cotton sheet.

[0046] 3. When the third rotating cylinder rotates forward by 90 degrees in the present invention, the third rotating cylinder stops rotating. At this time, the first spherical structure disengages from the first connecting layer, enabling the first spherical structure to form a spherical joint with the fixed seat. The third spherical structure disengages from the third connecting layer, enabling the third spherical structure to form a spherical joint with the connecting seat. The second locking mechanism makes the third sliding member form a sliding connection with the second sliding cylinder, enables the second sliding cylinder to form a sliding connection with the first connecting cylinder, and turns the connecting component into a flexible mechanism. When the third rotating cylinder rotates backward by 90 degrees, the first spherical structure presses against the first connecting layer, enabling the first spherical structure to form a fixed connection with the fixed seat. The third spherical structure presses against the third connecting layer, enabling the third spherical structure to form a fixed connection with the connecting seat. The second locking mechanism makes the third sliding member form a fixed connection with the second sliding cylinder, enables the second sliding cylinder to form a fixed connection with the first connecting cylinder, and turns the connecting component into a rigid mechanism.

[0047] 4. When the second rotating cylinder rotates forward in the present invention, it drives the second fixed cylinder to rotate forward. When the second fixed cylinder stops rotating, the extrusion force of the second extrusion surface on the second sliding plate disappears, reducing the friction between the second extrusion structure and the inner wall of the first connecting cylinder, and enabling the second sliding cylinder to form a sliding connection with the first connecting cylinder. When the third rotating cylinder stops rotating, the third fixed cylinder stops rotating. The extrusion force of the third extrusion surface on the third sliding plate disappears, reducing the friction between the third extrusion structure and the inner wall of the second sliding cylinder, and enabling the third sliding member to form a sliding connection with the second sliding cylinder, turning the connecting component into a flexible mechanism. When the second rotating cylinder rotates backward, it drives the second fixed cylinder to rotate backward. When the second fixed cylinder stops rotating, the second extrusion structure presses against the inner wall of the first connecting cylinder, enabling the second sliding cylinder to form a fixed connection with the first connecting cylinder. The third extrusion structure presses against the inner wall of the second sliding cylinder, enabling the third sliding member to form a fixed connection with the second sliding cylinder, and turning the connecting component into a rigid mechanism.

[0048] 5. In the present invention, the gear mechanism drives the threaded cylinder to rotate forward, reducing the pressure of the pressure solution in the first cavity. At this time, under the elastic force of the fourth elastic member, the fixed sleeve moves upward, causing the sliding seat to move towards the connecting seat until the distance between the sliding seat and the connecting seat is minimized. The gear mechanism drives the threaded cylinder to rotate backward, increasing the pressure of the pressure solution in the first cavity, stretching the bladder, and causing the sliding seat to move downward until the pressure of the hemostatic cotton sheet on the hemostatic site is satisfied.

Detailed implementation manner

[0068] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0069] As Figures 1 - 17 shown, a hemostatic compression device for medical care includes a fixed seat 11, a connecting seat 12, a sliding seat 13, a mounting seat 14, a conveyor belt 15 and a hemostatic cotton sheet 16;

[0070] A connecting seat 12 is arranged below the fixed seat 11; the connecting seat 12 and the fixed seat 11 are connected by a connecting member 2; the connecting member 2 is used to adjust the position of the connecting seat 12;

[0071] The lower end of the connecting seat 12 is slidably connected to the sliding seat 13; the lower end of the sliding seat 13 is slidably connected to the mounting seat 14; a conveyor belt 15 is connected to the mounting seat 14; the conveyor belt 15 is in a tensioned state; a hemostatic cotton sheet 16 is pasted on the outer side wall of the outer ring of the conveyor belt 15;

[0072] A first motor 3 is connected to the connecting member 2; the connecting member 2 and the first motor 3 are connected by a first locking member 4; the first locking member 4 is used to change the state of the connecting member 2; the sliding seat 13 and the first motor 3 are connected by a second transmission member 5; the second transmission member 5 is used to drive the sliding seat 13 to move;

[0073] A third power member 6 is provided on the mounting seat 14; the third power member 6 is used to drive the mounting seat 14 to move; the third power member 6 is used to drive the conveyor belt 15 to move.

[0074] During operation, the medical staff makes the rotating shaft of the first motor 3 rotate forward through the controller. When the rotating shaft of the first motor 3 rotates forward, the connecting member 2 is changed into a flexible mechanism through the first locking member 4, so that the connecting member 2 can automatically deform following the position of the connecting seat 12 (at this time, the distance between the sliding seat 13 and the connecting seat 12 is the smallest, and the distance between the mounting seat 14 and the sliding seat 13 is the largest). The medical staff moves the mounting seat 14 to the hemostatic part, so that the hemostatic cotton sheet 16 below the conveyor belt 15 is directly opposite to the hemostatic part. Subsequently, the medical staff makes the rotating shaft of the first motor 3 rotate backward through the controller. At the initial stage when the rotating shaft of the first motor 3 rotates backward, the connecting member 2 is changed into a rigid mechanism through the first locking member 4, and the connecting member 2 fixes the position of the connecting seat 12. When the rotating shaft of the first motor 3 rotates backward, the second transmission member 5 makes the sliding seat 13 move to the side away from the connecting seat 12, so that the sliding seat 13 moves towards the hemostatic part, making the mounting seat 14 and the conveyor belt 15 move towards the hemostatic part, so that the hemostatic cotton sheet 16 below the conveyor belt 15 abuts against the hemostatic part. After the pressure of the hemostatic cotton sheet 16 on the hemostatic part meets the requirements, the rotating shaft of the first motor 3 stops rotating, so that the hemostatic cotton sheet 16 presses on the hemostatic part to perform compressive hemostasis on the hemostatic part; after the compressive hemostasis is completed, the medical staff makes the rotating shaft of the first motor 3 rotate forward through the controller. At the initial stage when the rotating shaft of the first motor 3 rotates forward, the connecting member 2 is changed into a flexible mechanism through the first locking member 4, so that the connecting member 2 can automatically deform following the position of the connecting seat 12, facilitating the movement of the connecting seat 12. When the rotating shaft of the first motor 3 rotates forward, the second transmission member 5 makes the sliding seat 13 move towards the connecting seat 12, making the distance between the sliding seat 13 and the connecting seat 12 the smallest, facilitating the next use;

[0075] During the process of compression hemostasis, it is necessary to replace the hemostatic cotton sheet 16. At this time, the medical staff makes the third power component 6 work through the controller. The third power component 6 first moves the mounting seat 14 to one side of the sliding seat 13, moves the conveyor belt 15 to one side of the sliding seat 13, and separates the hemostatic cotton sheet 16 from the hemostatic site. When the distance between the mounting seat 14 and the sliding seat 13 is the smallest, the mounting seat 14 stops moving. Subsequently, the third power component 6 drives the conveyor belt 15 to move, drives the current hemostatic cotton sheet 16 to move, and moves the next unused hemostatic cotton sheet 16 towards the hemostatic site. When the next unused hemostatic cotton sheet 16 moves above the hemostatic site, the conveyor belt 15 stops moving. Subsequently, the third power component 6 drives the mounting seat 14 to move downward, making the distance between the mounting seat 14 and the sliding seat 13 the largest, and making the unused hemostatic cotton sheet 16 contact the hemostatic site, completing the replacement of the hemostatic cotton sheet 16 and improving the convenience of the hemostatic compression device; when the conveyor belt 15 drives the hemostatic cotton sheet 16 to move, the hemostatic cotton sheet 16 has been separated from the hemostatic site, preventing the hemostatic cotton sheet 16 from rubbing against the hemostatic site and preventing the friction from exacerbating bleeding, ensuring the hemostatic effect; before and after the replacement of the hemostatic cotton sheet 16, the sliding seat 13 remains stationary, and the distance between the mounting seat 14 and the sliding seat 13 remains unchanged. Therefore, the pressure on the hemostatic site before and after the replacement of the hemostatic cotton sheet 16 is consistent, ensuring the hemostatic effect.

[0076] The third power component 6 includes a rotating member 61, a third connecting shaft 62, a first connecting shaft 63, a swinging member 64, and a third motor 65;

[0077] The rotating members 61 are arranged on the mounting seat 14 at intervals; the rotating members 61 are rotatably connected to the mounting seat 14; a third connecting shaft 62 is fixedly connected to one of the rotating members 61; the conveyor belt 15 is sleeved outside the rotating member 61;

[0078] The first connecting shaft 63 is rotatably connected to the mounting seat 14; a swinging member 64 is fixedly connected to the first connecting shaft 63; a third motor 65 is fixedly connected to the mounting seat 14; the first connecting shaft 63 rotates synchronously with the rotating shaft of the third motor 65;

[0079] A first gear 66 is fixedly connected to the first connecting shaft 63; the first gear 66 is an incomplete gear; a second gear 67 is rotatably connected to the mounting seat 14; a third gear 68 is fixedly connected to the third connecting shaft 62;

[0080] Sliding structures 141 are symmetrically arranged at the upper end of the mounting seat 14; the sliding structures 141 are slidably connected to the sliding seat 13; a connecting plate 142 is connected to the mounting seat 14; both ends of the connecting plate 142 are fixedly connected to the two sliding structures 141 respectively; first elastic members 143 are symmetrically arranged at both ends of the connecting plate 142.

[0081] When the hemostatic cotton sheet 16 needs to be replaced, medical staff operate the third motor 65 through the controller. The third motor 65 drives the first connecting shaft 63 to rotate counterclockwise for one circle. The first connecting shaft 63 drives the swinging member 64 to rotate counterclockwise for one circle, causing the distal arc surface of the swinging member 64 to rotate downward to the side (when not rotated, the swinging member 64 is in a vertical state, the distal arc surface of the swinging member 64 is directly above the first connecting shaft 63, and the distal arc surface of the swinging member 64 abuts against the lower end surface of the sliding seat 13, and the distance between the mounting seat 14 and the sliding seat 13 is the largest). At this time, under the elastic force of the first elastic member 143 (the upper end of the first elastic member 143 abuts against the connecting plate 142, and the lower end of the first elastic member 143 abuts against the sliding seat 13), the connecting plate 142 moves upward, causing the mounting seat 14 to move upward. During this process, the gear structure of the first gear 66 does not mesh with the second gear 67, the second gear 67 and the third gear 68 do not move, the third connecting shaft 62 and the rotating member 61 do not move, and the conveyor belt 15 does not move until the swinging member 64 swings to a horizontal state. At this time, the upper end surface of the mounting seat 14 abuts against the lower end surface of the sliding seat 13, the distance between the mounting seat 14 and the sliding seat 13 is the smallest, and the mounting seat 14 stops moving. At this time, the gear structure of the first gear 66 starts to mesh with the second gear 67. The first connecting shaft 63 drives the swinging member 64 to continue rotating, driving the second gear 67 to rotate, driving the third gear 68 to rotate, driving the third connecting shaft 62 to rotate, driving the rotating member 61 to rotate, driving the conveyor belt 15 to move, and driving the hemostatic cotton sheet 16 to move. When the swinging member 64 rotates to the horizontal state again, the gear structure of the first gear 66 does not mesh with the second gear 67, causing the conveyor belt 15 to stop moving. The first connecting shaft 63 drives the swinging member 64 to continue rotating, causing the distal arc surface of the swinging member 64 to abut against the lower end surface of the sliding seat 13 again, resisting the elastic force of the first elastic member 143, causing the mounting seat 14 to move downward until the swinging member 64 rotates to the vertical state again. At this time, the distance between the mounting seat 14 and the sliding seat 13 is the largest, and the hemostatic cotton sheet 16 abuts against the hemostatic part again, completing the replacement of the hemostatic cotton sheet 16.

[0088] When the first locking member 4 makes the connecting member 2 into a flexible mechanism, the first spherical structure 211 forms a ball joint with the fixed seat 11, the third spherical structure 231 forms a ball joint with the connecting seat 12, the second sliding cylinder 22 forms a sliding connection with the first connecting cylinder 21, and the third sliding member 23 forms a sliding connection with the second sliding cylinder 22, enabling the connecting member 2 to automatically deform following the position of the connecting seat 12, facilitating the movement of the conveyor belt 15 to different hemostatic sites and improving the convenience of the hemostatic compression device; when the first locking member 4 makes the connecting member 2 into a rigid mechanism, the first spherical structure 211 forms a fixed connection with the fixed seat 11, the third spherical structure 231 forms a fixed connection with the connecting seat 12, the second sliding cylinder 22 forms a fixed connection with the first connecting cylinder 21, and the third sliding member 23 forms a fixed connection with the second sliding cylinder 22, keeping the position of the connecting seat 12 immovable and improving the stability after the connecting seat 12 is fixed.

[0089] The first locking member 4 includes a first locking mechanism and a second locking mechanism; the first locking mechanism includes a first rotating rod 41, a second rotating cylinder 42, and a third rotating cylinder 43;

[0090] The first rotating rod 41 is rotatably connected within the first connecting cylinder 21; one end of the first rotating rod 41 is provided with a first rod-shaped structure 411; a first spiral groove 4111 is provided on the side wall of the first rod-shaped structure 411; the second rotating cylinder 42 is rotatably connected within the second sliding cylinder 22; the first rotating rod 41 is slidably connected within the second rotating cylinder 42;

[0091] The third rotating cylinder 43 is rotatably connected within the third sliding member 23; one end of the third rotating cylinder 43 is provided with a third rod-shaped structure 431; a third spiral groove 432 is provided on the side wall of the third rod-shaped structure 431; the second rotating cylinder 42 is slidably connected within the third rotating cylinder 43; the first rotating rod 41, the second rotating cylinder 42, and the third rotating cylinder 43 rotate synchronously;

[0092] A first limiting member 44 is slidably connected to the first spherical structure 211; one end of the first limiting member 44 is provided with a first spherical surface structure 441; the other end of the first limiting member 44 is sleeved on the first rod-shaped structure 411; a first driving member 45 is connected to the first limiting member 44; the first driving member 45 abuts in the first spiral groove 4111;

[0093] A third limiting member 46 is slidably connected to the third spherical structure 231; one end of the third limiting member 46 is provided with a third spherical surface structure 461; the other end of the third limiting member 46 is sleeved on the third rod-shaped structure 431; a third driving member 47 is connected to the third limiting member 46; the third driving member 47 abuts in the third spiral groove 432;

[0094] A third rotating shaft 33 is rotatably connected to the third sliding member 23; the third rotating cylinder 43 and the third rotating shaft 33 are driven by a bevel gear mechanism 34; the third rotating shaft 33 rotates synchronously with the rotating shaft of the first motor 3.

[0095] In the initial stage of the forward rotation of the rotating shaft of the first motor 3, the rotating shaft of the first motor 3 drives the third rotating shaft 33 to rotate. The third rotating shaft 33 drives the third rotating cylinder 43 to rotate forward through the bevel gear mechanism 34, so that the third rotating cylinder 43, the second rotating cylinder 42, and the first rotating rod 41 rotate synchronously, driving the third rod-shaped structure 431 and the first rod-shaped structure 411 to rotate. When the first rod-shaped structure 411 rotates, the side wall of the first spiral groove 4111 generates a force on the first driving member 45, causing the first driving member 45 to move towards the third spherical structure 231, and causing the first limiting member 44 to move towards the third spherical structure 231. When the third rod-shaped structure 431 rotates, the side wall of the third spiral groove 432 generates a force on the third driving member 47, causing the third driving member 47 to move towards the first spherical structure 211, and causing the third limiting member 46 to move towards the first spherical structure 211. When the third rotating cylinder 43 rotates forward by 90 degrees, the bottom surface of the third connecting groove 462 (the third connecting groove 462 is provided on the third limiting member 46, the end of the third rod-shaped structure 431 abuts against the third connecting groove 462, the first connecting groove 442 is provided on the first limiting member 44, and the end of the first rod-shaped structure 411 abuts against the first connecting groove 442) abuts against the end surface of the third rod-shaped structure 431, the third limiting member 46 stops moving, the third rod-shaped structure 431 stops rotating, and the third rotating cylinder 43 stops rotating. At this time, the first spherical structure 441 disengages from the first connecting layer 111, enabling the first spherical structure 211 to form a spherical joint with the fixed seat 11. The third spherical structure 461 disengages from the third connecting layer 121, enabling the third spherical structure 231 to form a spherical joint with the connecting seat 12. While the third rotating cylinder 43 rotates forward, the second locking mechanism enables the third sliding member 23 to form a sliding connection with the second sliding cylinder 22, enabling the second sliding cylinder 22 to form a sliding connection with the first connecting cylinder 21, and enabling the connecting component 2 to become a flexible mechanism. After the connecting component 2 becomes a flexible mechanism, the rotating shaft of the first motor 3 continues to rotate forward. At this time, the bevel gear mechanism 34 loses its transmission function, causing the third rotating cylinder 43 to remain stationary. The sliding seat 13 is driven to move towards the connecting seat 12 through the second transmission component 5. When the distance between the sliding seat 13 and the connecting seat 12 is minimized, the rotating shaft of the first motor 3 stops rotating (when moving towards the connecting seat 12 towards the hemostasis site, this process can be omitted. After the connecting component 2 becomes a flexible mechanism, the rotating shaft of the first motor 3 stops rotating);

[0096] In the initial stage when the rotating shaft of the first motor 3 rotates in the reverse direction, the rotating shaft of the first motor 3 drives the third rotating shaft 33 to rotate. The third rotating shaft 33 drives the third rotating cylinder 43 to rotate in the reverse direction through the bevel gear mechanism 34, causing the third rotating cylinder 43, the second rotating cylinder 42, and the first rotating rod 41 to rotate synchronously, driving the third rod-shaped structure 431 and the first rod-shaped structure 411 to rotate. When the first rod-shaped structure 411 rotates, the side wall of the first spiral groove 4111 exerts a force on the first driving member 45, causing the first driving member 45 to move away from the third spherical structure 231, and causing the first limiting member 44 to move away from the third spherical structure 231. When the third rod-shaped structure 431 rotates, the side wall of the third spiral groove 432 exerts a force on the third driving member 47, causing the third driving member 47 to move away from the first spherical structure 211, and causing the third limiting member 46 to move away from the first spherical structure 211. When the third rotating cylinder 43 rotates 90 degrees in the reverse direction, the first spherical surface structure 441 presses on the first connecting layer 111, causing the first spherical structure 211 to form a fixed connection with the fixed seat 11. The third spherical surface structure 461 presses on the third connecting layer 121, causing the third spherical structure 231 to form a fixed connection with the connecting seat 12. While the third rotating cylinder 43 rotates in the reverse direction, the second locking mechanism makes the third sliding member 23 form a fixed connection with the second sliding cylinder 22, makes the second sliding cylinder 22 form a fixed connection with the first connecting cylinder 21, and makes the connecting component 2 become a rigid mechanism. After the connecting component 2 becomes a rigid mechanism, the rotating shaft of the first motor 3 continues to rotate in the reverse direction. At this time, the bevel gear mechanism 34 loses its transmission function, causing the third rotating cylinder 43 to remain stationary, and driving the sliding seat 13 to move towards the hemostatic part through the second transmission component 5. After the pressure of the hemostatic cotton sheet 16 on the hemostatic part meets the requirements, the rotating shaft of the first motor 3 stops rotating (when it is not necessary for the sliding seat 13 to move towards the hemostatic part, after the connecting component 2 becomes a rigid mechanism, directly stop the rotating shaft of the first motor 3).

[0097] The second locking mechanism includes a second sliding plate 48, a second fixed cylinder 49, a third sliding plate 31, and a third fixed cylinder 32; a second connecting portion 221 is provided at one end of the second sliding cylinder 22 close to the first spherical structure 211; the second sliding plate 48 is symmetrically arranged on the second connecting portion 221; a second pressing structure 481 is provided on one side of each of the two second sliding plates 48 away from each other; the second pressing structure 481 is slidably connected to the second connecting portion 221; a second fixed cylinder 49 is fixedly connected to one end of the second rotating cylinder 42 close to the first spherical structure 211; a second pressing surface 491 is symmetrically provided on the second fixed cylinder 49;

[0098] One end of the third sliding member 23 close to the first spherical structure 211 is provided with a third connecting portion 232; third sliding plates 31 are symmetrically arranged on the third connecting portion 232; third pressing structures 311 are arranged on one sides of the two third sliding plates 31 away from each other; the third pressing structures 311 are slidably connected to the third connecting portion 232; one end of the third rotating cylinder 43 close to the first spherical structure 211 is fixedly connected to a third fixed cylinder 32; third pressing surfaces 321 are symmetrically arranged on the third fixed cylinder 32.

[0099] When the second rotating cylinder 42 rotates forward, it drives the second fixed cylinder 49 to rotate forward, drives the second pressing surface 491 to rotate. When the third rotating cylinder 43 stops rotating, the second fixed cylinder 49 stops rotating. At this time, the second pressing surface 491 disengages from the second sliding plate 48, and the pressing force of the second pressing surface 491 on the second sliding plate 48 disappears, reducing the friction between the second pressing structure 481 and the inner wall of the first connecting cylinder 21, enabling the second sliding cylinder 22 and the first connecting cylinder 21 to form a sliding connection. When the third rotating cylinder 43 rotates forward, it drives the third fixed cylinder 32 to rotate forward, drives the third pressing surface 321 to rotate. When the third rotating cylinder 43 stops rotating, the third fixed cylinder 32 stops rotating. At this time, the third pressing surface 321 disengages from the third sliding plate 31, and the pressing force of the third pressing surface 321 on the third sliding plate 31 disappears, reducing the friction between the third pressing structure 311 and the inner wall of the second sliding cylinder 22, enabling the third sliding member 23 and the second sliding cylinder 22 to form a sliding connection, making the connecting component 2 a flexible mechanism;

[0100] When the second rotating cylinder 42 rotates reversely, it drives the second fixed cylinder 49 to rotate reversely, drives the second pressing surface 491 to rotate. When the third rotating cylinder 43 stops rotating, the second fixed cylinder 49 stops rotating. At this time, the second pressing surface 491 presses on the second sliding plate 48, causing the second pressing structure 481 to press on the inner wall of the first connecting cylinder 21, enabling the second sliding cylinder 22 and the first connecting cylinder 21 to form a fixed connection. When the third rotating cylinder 43 rotates reversely, it drives the third fixed cylinder 32 to rotate reversely, drives the third pressing surface 321 to rotate. When the third rotating cylinder 43 stops rotating, the third fixed cylinder 32 stops rotating. At this time, the third pressing surface 321 presses on the third sliding plate 31, causing the third pressing structure 311 to press on the inner wall of the second sliding cylinder 22, enabling the third sliding member 23 and the second sliding cylinder 22 to form a fixed connection, making the connecting component 2 a rigid mechanism.

[0107] When the rotating shaft of the first motor 3 rotates forward, the threaded cylinder 54 is driven to rotate forward through the gear mechanism 57, the fourth shaft-like structure 531 is driven to move, the fourth sliding plate 53 is driven to move towards the open end of the fourth fixing cylinder 52, reducing the pressure of the pressure solution in the first cavity (the first cavity is formed by the fourth sliding plate 53 and the closed end of the fourth fixing cylinder 52, and the first cavity, the first connecting pipe 58 and the bladder 51 are filled with pressure solution). At this time, under the elastic force of the fourth elastic member 56, the fixing sleeve 55 moves upward, the fourth rod-like structure 132 moves upward, and the sliding seat 13 moves towards the connecting seat 12 until the distance between the sliding seat 13 and the connecting seat 12 is the smallest;

[0108] When the rotating shaft of the first motor 3 rotates reversely, the threaded cylinder 54 is driven to rotate reversely through the gear mechanism 57, the fourth shaft-like structure 531 is driven to move, the fourth sliding plate 53 is driven to move towards the closed end of the fourth fixing cylinder 52, increasing the pressure of the pressure solution in the first cavity, causing the pressure solution to move into the bladder 51, and the bladder 51 (the bladder 51 can only stretch up and down and cannot expand horizontally) stretches, resisting the elastic force of the fourth elastic member 56, and the sliding seat 13 moves downward until the pressure of the hemostatic cotton sheet 16 on the hemostatic part is satisfied.

[0111] After the third rotating cylinder 43 stops rotating, the sixth bevel gear 342 and the fifth bevel gear 341 stop rotating, and the third rotating shaft 33 continues to rotate, causing the fifth driving member 345 and the fifth sliding plate 343 to move into the fifth installation groove, causing the fifth driving member 345 to disengage from the fifth driving groove, forming a rotational connection between the third rotating shaft 33 and the fifth bevel gear 341, and causing the third rotating shaft 33 to continue rotating to drive the sliding seat 13 to move through the second transmission member 5.
