Description

Technical Field

[0001] The present invention particularly relates to a minimally invasive postoperative wound compression device. Background Art

[0002] Clinically, some cardiac interventional surgeries are performed through the femoral artery. After the surgery, the wound needs to be compressed to stop bleeding. The existing method is: after the surgery, the doctor places a cup-shaped block on the wound at the femoral artery, and then compresses and fixes the block by wrapping it with tape.

[0003] However, this method will inevitably greatly prolong the operation time because the surgeon needs to wrap the tape multiple times. In addition, during the postoperative clinical observation process, the medical staff needs to remove the tape, and after completing the dressing change or observation, it needs to be fixed again with the tape. This will inevitably increase the workload of the medical staff again. At the same time, the process of removing and tearing the tape will increase the patient's pain. Summary of the invention

[0004] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a minimally invasive postoperative wound compression device, which can conveniently compress and stop bleeding on the postoperative wound.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions: a minimally invasive postoperative wound compression device, comprising:

[0006] a baseboard that is supported under the patient's hips and right leg;

[0007] A pressing block, the bottom of which can be pressed tightly against the wound;

[0008] There are four hooks, and the four hooks are arranged on the side wall of the pressing block at circumferential intervals; and

[0009] There are four tensioning straps, the bottom ends of which are respectively fixed on the four corners of the bottom plate, and the top of each tensioning strap is provided with a connecting fixture which can fix the top of the tensioning strap on the hook.

[0010] Furthermore, the pressing block is a cylinder, a circle of sliding grooves is arranged on the side wall of the pressing block, the cross section of the sliding grooves is T-shaped, and a sliding block which can be clamped in the sliding grooves is arranged on the hook, and the sliding block can slide along the sliding grooves.

[0011] Furthermore, a screw rod is provided on the sliding block, the top end of the screw rod extends out of the sliding groove, and a locking nut is sleeved on the screw rod. When the locking nut is rotated, the locking nut can be pressed against the outer wall of the pressing block.

[0012] Furthermore, the connecting fixing member includes a Velcro surface and a Velcro thorn surface, and the Velcro surface and the Velcro thorn surface are fixed on the tensioning belt at intervals along the length direction of the tensioning belt. When the top end of the tensioning belt passes through the hook and is pulled back in the opposite direction, the Velcro surface and the Velcro thorn surface on the same tensioning belt can adhere to each other.

[0013] Furthermore, it also includes a secondary tension adjusting member, which is arranged in the middle of the tensioning belt and is used to reel in or unwind the tensioning belt.

[0014] Furthermore, the secondary tension adjustment member includes an outer shell, a winding rod, a rotating power source and a locking member. The two opposite side walls of the outer shell are respectively provided with a first through slot and a second through slot connected to the inner cavity thereof. The winding rod can be rotatably arranged in the outer shell. After the tensioning band is wound around the winding rod, the two ends of the tensioning band pass through the first through slot and the second through slot respectively. The rotating power source is connected to the winding rod to drive the winding rod to rotate clockwise or counterclockwise. When the winding rod rotates clockwise, the two ends of the tensioning band can be reeled in at the same time. When the winding rod rotates counterclockwise, the two ends of the tensioning band can be released at the same time. The locking member and the winding rod can prevent the winding rod from rotating counterclockwise.

[0015] Furthermore, the rotary power source comprises a rotary handle, and the rotary handle is arranged at the end of the winding rod.

[0016] Furthermore, the locking member includes a ratchet disk, a pawl and an elastic support member, the ratchet disk is sleeved and fixed on the winding rod, the pawl is arranged along the radial direction of the ratchet disk, and the elastic support member is connected between the pawl and the outer shell. When the ratchet disk rotates, the end of the pawl can slide along the ratchet teeth of the ratchet disk until it is inserted between two adjacent ratchet teeth.

[0017] Furthermore, a pulling handle is provided on the ratchet.

[0018] Furthermore, the secondary tension adjusting member also includes a spiral spring piece, and both ends of the winding rod are sleeved with a spiral spring piece, the inner end of the spiral spring piece is fixed to the winding rod, and the outer end of the spiral spring piece is fixed to the outer shell.

[0019] Beneficial effects of the present invention:

[0020] When using the above-mentioned minimally invasive postoperative wound compression device, before the operation, the base plate is first placed on the operating table, supported under the buttocks and right leg, and then normal operation is performed. After the operation, the four tensioning belts are tightened and fixedly connected with the corresponding hooks one by one.

[0021] The use of this minimally invasive postoperative wound compression device can avoid the need for surgeons to wrap tape multiple times to fix the wound after traditional minimally invasive cardiac intervention surgery. At the same time, with the device, during the postoperative clinical observation process, medical staff only need to loosen the tensioning belt and then remove the pressure block to observe the wound or change the dressing. After completing the wound observation or dressing change, the pressure block is pressed on the wound again, and the four tensioning belts are tightened and fixed to the corresponding hooks one by one.

[0022] The above minimally invasive postoperative wound compression device can quickly complete the compression and hemostasis of the wound after cardiac surgery, thereby saving operation time and avoiding the pain caused by pulling the patient's skin. During clinical observation, it can be easily disassembled and reinstalled, thereby greatly reducing the workload of medical staff. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the invention is not limited by the specific implementation disclosed below.

[0033] See also Figures 1 to 6 The minimally invasive postoperative wound compression device provided by the present invention includes a base plate 100, a pressing block 200, a hook 300 and a tensioning belt 400.

[0034] Specifically, it is supported under the patient's buttocks and right leg. The bottom of the pressing block 200 can be pressed tightly on the femoral artery wound. There are four hooks 300, and the four hooks 300 are arranged on the side wall of the pressing block 200 at intervals in the circumferential direction. There are four tensioning bands 400, and the bottom ends of the four tensioning bands 400 are respectively fixed to the four corners of the bottom plate 100, and the top of each tensioning band 400 is provided with a connecting fixture that can fix the top of the tensioning band 400 to the hook 300.

[0035] When in use, before the operation, the base plate 100 is placed on the operation table, supported under the buttocks and right leg, and then the normal operation is performed. After the operation, the four tensioning belts 400 are tightened and fixedly connected with the corresponding hooks 300 one by one.

[0036] The use of this minimally invasive postoperative wound compression device can avoid the need for surgeons to wrap tape multiple times to fix the wound after traditional minimally invasive cardiac intervention surgery. At the same time, with the use of the device, during the postoperative clinical observation process, medical staff only need to loosen the tensioning belt 400 and then remove the pressure block 200 to observe the wound or change the dressing. After completing the observation of the wound or the dressing change, the pressure block 200 is pressed against the wound again, and the four tensioning belts 400 are tightened and fixedly connected to the corresponding hooks 300 one by one.

[0037] The above minimally invasive postoperative wound compression device can quickly complete the compression and hemostasis of the wound after cardiac surgery, thereby saving operation time and avoiding the pain caused by pulling the patient's skin. During clinical observation, it can be easily disassembled and reinstalled, thereby greatly reducing the workload of medical staff.

[0038] As a preferred embodiment, the pressing block 200 is a cylinder, a circle of slide grooves 210 are set on the side wall of the pressing block 200, the cross section of the slide groove 210 is T-shaped, and a slider 310 that can be stuck in the slide groove 210 is set on the hook 300, and the slider 310 can move along the slide groove 210.

[0039] When in use, the position of the hook 300 can be adjusted according to actual conditions to facilitate the fixation of the tensioning belt 400.

[0040] In addition, in a specific implementation, a screw rod 320 may be provided on the slider 310, and the top end of the screw rod 320 extends out of the slide slot 210. A locking nut 330 is sleeved on the screw rod 320, and the locking nut 330 is rotated so that the locking nut 330 can be pressed against the outer wall of the pressing block 200. When in use, after the position of the hook 300 is adjusted, the locking nut 330 can be rotated until the locking nut 330 is pressed against the outer wall of the pressing block 200, so that the position of the hook 300 can be fixed to prevent the hook 300 from moving arbitrarily.

[0041] In this embodiment, the connecting and fixing member includes a Velcro surface 410 and a Velcro thorn surface 420. The Velcro surface 410 and the Velcro thorn surface 420 are fixed on the tensioning belt 400 at intervals along the length direction of the tensioning belt 400. When the top end of the tensioning belt 400 passes through the hook 300 and is pulled back in the reverse direction, the Velcro surface 410 and the Velcro thorn surface 420 on the same tensioning belt 400 can self-adhere to each other, completing the tightening and fixing of the tensioning belt.

[0042] By adopting this method, not only the tensioning degree of the tensioning belt 400 can be adjusted, but also the tensioning belt 400 can be conveniently fixed.

[0043] As a preferred embodiment, the device also includes a secondary tension adjustment member 500, which is arranged in the middle of the tensioning band 400 and is used to reel in or release the tensioning band 400, and further adjust the tensioning degree of the tensioning band 400 to achieve an ideal hemostatic effect.

[0044] Specifically, the secondary tension adjusting member 500 includes a housing 510, a winding rod 520, a rotation power source 530 and a locking member 540. The housing 510 has two opposite side walls respectively provided with a first through slot and a second through slot communicating with the inner cavity thereof. The winding rod 520 is rotatably arranged in the housing 510. After the tensioning band 400 is wound around the winding rod 520, the two ends of the tensioning band 400 pass through the first through slot and the second through slot respectively. The rotation power source 530 is connected to the winding rod 520 and is used to drive the winding rod 520 to rotate clockwise or counterclockwise. When the winding rod 520 rotates clockwise, the two ends of the tensioning band can be wound up at the same time. When the winding rod 520 rotates counterclockwise, the two ends of the tensioning band 400 can be released at the same time. The locking member 540 and the winding rod 520 can prevent the winding rod 520 from rotating counterclockwise.

[0045] When in use, all the tensioning belts 400 are first fixed on the hook 300. When the tensioning force is found to be insufficient, the winding rod 520 can be driven to rotate clockwise by the rotating power source 530 to retract the two ends of the tensioning belt 400 toward the housing 510, so that the tensioning belt 400 can be tightened again. Since the locking member 540 can prevent the winding rod 520 from rotating counterclockwise, it can be ensured that the tensioning degree cannot be adjusted at will.

[0046] In this embodiment, the rotary power source 530 includes a rotary handle, which is disposed at the end of the winding rod 520. The rotary handle is used to conveniently drive the winding rod 520 to rotate. Of course, in other embodiments, the rotary power source 530 may be a rotary motor or other methods.

[0047] In this embodiment, the locking member 540 includes a ratchet disc 541, a pawl 542 and an elastic support member 543. The ratchet disc 541 is sleeved and fixed on the winding rod 520, the pawl 542 is arranged along the radial direction of the ratchet disc 541, and the elastic support member 543 is connected between the pawl 542 and the housing 510. When the ratchet disc 541 rotates, the end of the pawl 542 can slide along the ratchet teeth of the ratchet disc 541 until it is inserted between two adjacent ratchet teeth, thereby preventing the winding rod 520 from rotating counterclockwise.

[0048] In a normal state, under the action of the elastic support member 543, the pawl 542 is inserted between the two ratchet teeth of the ratchet disc 541. When the rotary power source 530 drives the winding rod 520 to rotate clockwise, the ratchet can be driven to rotate clockwise while winding.

[0049] In this embodiment, a pulling handle 544 is provided on the ratchet 542. When the winding rod 520 needs to rotate in the reverse direction, the ratchet 542 can be pulled back and disengaged from the ratchet teeth by driving the pulling handle 544, and the winding rod 520 can be rotated in the reverse direction to release the line.

[0050] As a more preferred embodiment, the secondary tension adjusting member 500 further includes a spiral spring piece 545. The spiral spring pieces 545 are sleeved on both ends of the winding rod 520. The inner end of the spiral spring piece 545 is fixed to the winding rod 520, and the outer end of the spiral spring piece 545 is fixed to the housing 510. When the pawl 542 is disengaged from the ratchet, the winding rod 520 can automatically rotate counterclockwise to release the line under the action of the spiral spring piece 545, which is convenient for the next use.

[0051] Specific usage of the above minimally invasive postoperative wound compression device:

[0052] When in use, before the operation, the base plate 100 is placed on the operation table, and then the patient is placed on the operation table, and the base plate 100 is supported under the buttocks and right leg, and then the normal operation is performed. After the operation, the positions of the four hooks 300 are adjusted, and the corresponding positions of the hooks 300 are locked by the locking nuts 330, and then the four tensioning bands 400 are passed through the corresponding hooks 300 one by one, and then fixed by the Velcro surface 410 and the Velcro thorn surface 420. After the preliminary fixation of the four tensioning bands 400 is completed, the winding rod 520 can be rotated by rotating the handle to further adjust the tension of the tensioning band 400. When it is necessary to check the wound or change the dressing, the Velcro surface 410 and the thorn surface can be separated.

[0053] When the wound needs to be compressed again, the same steps as the previous steps can be used.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
