Description

Technical Field

[0001] The present invention particularly relates to a hemostatic device. Background Art

[0002] The packing hemostasis method is mainly used clinically after abscess incision and drainage, sebaceous cyst removal, and lipoma removal. Since a large cavity is left after tumor removal, but there is no clear blood vessel rupture or bleeding, it is impossible to stop bleeding by ligation or suture. Gauze can only be stuffed into the residual cavity, bandaged with sterile gauze, and fixed with a bandage to compress the tiny blood vessels and play a role in contraction and hemostasis.

[0003] The specific operation of the existing packing hemostasis method is: when packing, the medical staff generally presses the wound with the fingers of the left hand, piles the gauze strips above the wound with the right hand, and then presses the piled gauze strips into the wound cavity with the fingers of the left hand until the inner cavity of the wound is filled. Finally, a sterile gauze bandage is used to apply pressure to fix the appropriate pressure to shrink the ruptured tiny blood vessels, thereby achieving the effect of hemostasis.

[0004] This kind of packing method, since the whole process is completed by hand, and the speed of hand movement is directly related to the operation experience, this will inevitably directly affect the hemostatic effect. Summary of the invention

DETAILED DESCRIPTION

[0031] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0032] See also Figures 1 to 3 The present invention provides a hemostatic device, including a mounting plate 100, an outer cylinder 200, a wire winder 300, a packing belt 400, a wire remover 500 and a packing member 600.

[0033] Specifically, the outer cylinder 200 is arranged on the mounting plate 100, and a wire outlet hole 210 is provided at the bottom of the outer cylinder 200. The wire winder 300 can release the wire freely. The stuffing belt 400 is wound on the wire winder 300, and the end of the stuffing belt 400 passes through the outer cylinder 200 and can freely extend from the wire outlet hole 210. The wire puller 500 is arranged in the outer cylinder 200 and is connected to the stuffing belt 400, and is used to pull the gap of the stuffing belt 400 toward the wire outlet hole 210. The stuffing piece 600 includes a first motion driving source 610 and a plug 620. The first motion driving source 610 is connected to the plug 620, and can drive the plug 620 to move toward the wound 1 in the gap of the up and down movement of the wire puller 500, and press the stuffing belt 400 accumulated on the wound 1 into the wound 1.

[0034] When in use, the mounting plate 100 is placed vertically above the wound 1, and the wire outlet hole 210 is located directly above the wound 1. Then, the wire pusher 500 and the first motion driving source 610 are started, and the filling tape 400 in the gap of the wire pusher 500 is pushed downward, so that the filling tape 400 is accumulated above the wound 1. Then, the first motion driving source 610 drives the plug 620 to move toward the direction of the wound 1, and presses the filling tape 400 accumulated on the wound 1 into the wound 1.

[0035] By using the hemostatic device, the actions of stacking the packing tape 400 and inserting the packing tape 400 are both completed by mechanical equipment, thereby avoiding the situation where insufficient experience in manual packing hemostasis leads to slow movements and further causes hemostasis failure.

[0036] Specifically, the wire puller 500 includes a second motion driving source 510, a guide cylinder 520, a lever 530, a first elastic support member 540 and a stopper 550. The guide cylinder 520 is slidably arranged in the outer cylinder 200, and the second motion driving source 510 is connected to the guide cylinder 520 to drive the guide cylinder 520 to move downward along the axial direction of the outer cylinder 200. The upper and lower ends of the guide cylinder 520 are in an open state, the stuffing belt 400 passes through the guide cylinder 520, one end of the lever 530 is hinged to the inside of the guide cylinder 520 through a hinge, and the other end is a free end, and the distance between the stuffing belt 400 and the hinge is less than the length of the lever 530. One end of the first elastic support member 540 is arranged on the inner wall of the guide cylinder 520 and is located near the plug 620, and the other end is supported on the free end of the lever 530. The stopper 550 is disposed on the inner wall of the guide tube 520 and is located at a side away from the plug head 620 relative to the hinge, and can abut against the side wall of the lever 530 away from the plug head 620 .

[0037] During use, when the second motion driving source 510 drives the guide cylinder 520 to move downward, the end of the lever 530 pushes the packing belt 400 to be pulled downward, and the packing belt 400 moves downward and accumulates above the wound 1. When the second motion driving source 510 drives the guide cylinder 520 to move upward, the lever 530 sticks to the surface of the packing belt 400 and does not move. In this way, the packing belt 400 can be pulled out and accumulated above the wound 1.

[0038] In this embodiment, the second motion driving source 510 includes a first rotary power source 511 and a connecting rod 512 that can automatically extend and retract when subjected to axial pressure. In specific implementation, the first rotary power source 511 can use a motor that can rotate in both directions commonly used in the prior art. The first rotary power source 511 is fixed to the outer cylinder 200 through a bracket, and a slide groove that is connected to the inner cavity of the cylinder is provided on the side wall of the outer cylinder 200 along the height direction. One end of the connecting rod 512 is fixed to the rotating shaft of the first rotary power source 511, and the other end of the connecting rod 512 extends radially along the rotating shaft of the first rotary power source 511 until it passes through the slide groove and is hinged to the guide cylinder 520.

[0039] When the first rotation power source 511 moves forward or backward, it can drive the guide cylinder 520 to move downward or upward, thereby driving the lever 530 to move downward or slide upward.

[0040] As a preferred embodiment, the wire puller 500 further includes a second elastic support member 560. The second elastic support members 560 are provided in two positions in the guide cylinder 520, extend radially along the guide cylinder 520, and are supported on the side wall of the packing belt 400 away from the pull rod 530.

[0041] The two second elastic supporting members 560 can prevent the packing belt 400 from being separated from the lever 530, thereby preventing the lever from being empty.

[0042] As another preferred embodiment, the wire remover 500 further includes a guide wheel set 570. There are two guide wheel sets 570, which are arranged at intervals at the upper and lower ends of the guide cylinder 520, each guide wheel set 570 includes two guide wheels arranged oppositely, and the stuffing belt 400 passes sequentially between the two guide wheels of the two guide wheel sets 570, and the stuffing belt 400 located between the two guide wheel sets 570 is located on the same straight line as the central axis of the guide cylinder 520.

[0043] The guide wheel set 570 is used to ensure that the packing belt 400 falls vertically, thereby improving the accuracy of the stacking position.

[0044] In this embodiment, the first motion driving source 610 includes a second rotary power source 611, a swing rod 612 that can automatically extend and retract under axial pressure, and a slider 613. The swing rod 612 is connected to the rotation axis of the second rotary power source 611 and is driven to rotate by the second rotary power source 611. An arc-shaped guide groove is provided on the mounting plate 100, and the tail end of the guide groove is located directly below the outer cylinder 200. A slider 613 that can slide is clamped in the guide groove, and the tail end of the swing rod 612 is connected to the slider 613, and a plug 620 is provided on the slider 613.

[0045] When the second rotary power source 611 rotates, it drives the swing rod 612 to swing, and then drives the slider 613 to move in an arc shape, so as to drive the plug 620 to fill the gap in the wire drawing.

[0046] Specifically, the second rotating power source 611 includes a driving wheel 6111, a rotating shaft 6112, a driven wheel 6113 and a transmission member 6114. The driving wheel 6111 is sleeved and fixed on the power output shaft of the first rotating power source 511. The rotating shaft 6112 is rotatably arranged on the mounting plate 100, and the driven wheel 6113 is sleeved and fixed on the rotating shaft 6112. The transmission member 6114 is connected between the driving wheel 6111 and the driven wheel 6113, and one end of the swing rod 612 is fixed on the rotating shaft 6112, and the other end extends outward along the radial direction of the rotating shaft 6112.

[0047] In this way, the swinging motion of the swing rod 612 and the motion of the connecting rod 512 are completed by the first rotary power source 511, thereby ensuring the coordination of the motions of the plug 620 and the lever 530. Of course, in other embodiments, the second rotary power source 611 may also be a rotary motor. The rotary motor rotates circumferentially to coordinate its motion with the first rotary power source 511.

[0048] As a preferred embodiment, the device further includes a pressing plate 700. The pressing plate 700 is disposed at the bottom of the mounting plate 100 and forms an L shape with the mounting plate 100. The pressing plate 700 is provided with a through hole 710 that passes through from top to bottom. The through hole 710 is located at the bottom of the outlet hole 210, and the plug 620 and the packing tape 400 can pass through the through hole 710.

[0049] When in use, the pressing plate 700 can be pressed tightly against the tissue around the wound 1 , and the through hole 710 can be aligned with the wound 1 , so as to achieve the purpose of assisting hemostasis.

[0050] The above hemostatic device is used in the following ways:

[0051] When in use, the pressing plate 700 can be pressed against the tissue around the wound 1, and the through hole 710 can be aligned with the wound 1. At the same time, the mounting plate 100 can be kept in a vertical state. Then, the first rotating power source 511 can be started to drive the lever 530 and the connecting rod 512 to move, thereby causing the lever 530 and the plug 620 to move toward the wound 1, thereby achieving the purpose of braking the gauze strip.

[0052] By using the device, the actions of stacking the packing tape 400 and inserting the packing tape 400 in the entire packing hemostasis process are completed by mechanical equipment, thereby avoiding the situation where insufficient experience in manual packing hemostasis leads to slow movements and further causes hemostasis failure.
