Description

Technical Field

[0001] This invention relates to a compression hemostatic pad device for hepatobiliary surgical wounds, belonging to the field of hemostasis technology for hepatobiliary wounds. Background Technology

[0002] A hemostatic pad for hepatobiliary surgery is a medical device specifically designed for hepatobiliary and pancreatic surgery. Its core function is to quickly control bleeding from the surgical wound through physical compression, drug assistance, or electrocoagulation, thereby improving hemostasis efficiency and reducing the risk of complications. Chinese patent CN209574785U discloses a hemostatic device for hepatobiliary tumor surgery that achieves rapid hemostasis. However, while existing hemostatic pads are easy to apply pressure with, they cannot deliver medication evenly and synchronously in real time. Especially when performing procedures requiring precise compression of both sides of the wound, these devices cannot achieve adjustable clamping angles. Adding an automatic angle-adjusting circuit would increase the overall weight, making prolonged use during surgery impractical. Summary of the Invention

[0003] The purpose of this invention is to provide a compression hemostatic pad device for hepatobiliary surgery wounds, which solves the technical problems of existing hemostatic pads having no adjustable angle and no synchronous output of medication.

[0004] The present invention adopts the following technical solution: a hemostatic pad device for compression of surgical wounds in hepatobiliary surgery, comprising a vertically arranged fixed rod, a connecting block fixedly connected to the upper part of the fixed rod, a diagonally arranged movable rod connected to the connecting block via a rotating component, a first mounting component and a second mounting component respectively connected to the bottom of the fixed rod and the movable rod, a rotating support connected between the second mounting component and the movable rod, the axes of the rotating support and the rotating component being parallel and both being arranged laterally, a liquid inlet chamber respectively provided at the bottom of the first mounting component and the second mounting component, a hemostatic pad connected to the bottom of each liquid inlet chamber, a liquid inlet and a liquid outlet provided on each liquid inlet chamber, a medicine bottle installed on the connecting block, two flexible branch tubes connected to the medicine bottle, the outlets of the two flexible branch tubes respectively connected to the liquid inlets of the two liquid inlet chambers, and the liquid outlet connected to the hemostatic pad and used to guide the medicine into the hemostatic pad.

[0005] The connecting block has an internal cavity. One end of the rotating component is fixedly connected to a knob, and the other end is fixedly connected to a ratchet. The ratchet is located inside the internal cavity of the connecting block, and the knob is located outside the connecting block. An unlocking button is provided on one side of the rotating component on the connecting block. One end of the unlocking button is located outside the connecting block, and the other end is connected to a ratchet tooth that engages with the ratchet. The ratchet tooth is located in the internal cavity. A spring post is fixedly connected between the unlocking button and the ratchet tooth. The diameter of the unlocking button is larger than the diameter of the spring post. A first spring is sleeved on the spring post, and the first spring is located between the outer surface of the connecting block and the unlocking button.

[0006] The fixed rod is provided with a limiting rotating seat below the connecting block. The limiting rotating seat includes an internal tooth groove and a rotating tooth ring. The outer periphery of the internal tooth groove is fixed inside the fixed rod. The inner circumferential surface of the internal tooth groove is provided with internal teeth. The outer periphery of the rotating tooth ring is provided with external teeth that mesh with the internal teeth. A spring rod is fixedly connected to the center of the internal tooth groove. A second spring is sleeved on the spring rod. The spring rod passes through the center of the rotating tooth ring. A sliding sleeve located outside the fixed rod is fixedly connected to the rotating tooth ring. The sliding sleeve is concentrically sleeved on the outer periphery of the spring rod. One end of the second spring is connected to the end of the spring rod away from the rotating tooth ring. The other end of the second spring is connected to the end of the sliding sleeve near the rotating tooth ring. The outer periphery of the end of the sliding sleeve away from the rotating tooth ring is provided with an annular winding groove. A fixed support is provided on the second mounting part. A traction line is connected to the fixed support. One end of the traction line is connected to the fixed support. The other end of the traction line is wound in the winding groove.

[0007] The bottom end of the inner tooth groove is a closed end, and a connecting post is fixed at the center of the closed end. The spring rod is fixedly connected to the connecting post. An inner stop block is provided on the inner side of the end of the sliding sleeve near the rotating tooth ring, and an outer stop block is provided on the end of the spring rod away from the rotating tooth ring. The two ends of the second spring are respectively connected to the inner stop block and the outer stop block.

[0008] A support frame is installed on the side of the connecting block away from the movable rod. The medicine bottle is installed in the support frame. The bottom of the medicine bottle is provided with a squeezing chamber. A flexible pipe is connected to the bottom of the squeezing chamber. The two flexible branch pipes are connected in parallel at the outlet of the flexible pipe.

[0009] The medicine bottle is provided with a first one-way valve at the inlet at the top and a second one-way valve at the outlet at the bottom of the squeezing chamber. The first one-way valve is used to allow air to enter the medicine bottle and the second one-way valve is used to allow liquid to exit the squeezing chamber through the flexible pipe.

[0010] A rubber sleeve is fixedly fitted around the outer periphery of the extrusion chamber, and the rubber sleeve is fixedly connected to the side of the connecting block.

[0011] Each hemostatic pad has a drug inlet at the top, which is sealed to the outlet of the inlet chamber via threads.

[0012] The hemostatic pad has a drug distribution net made of medical plastic inside. The drug distribution net includes a main pipe and several outlet branches connected in parallel with the main pipe. The main pipe is set upward and located inside the drug inlet. Each outlet branch has a mesh structure and the outlet of each outlet branch is set downward. Each outlet branch is evenly distributed on the bottom surface of the hemostatic pad.

[0013] The top of the fixed rod is connected to a handle via a hinge support. The hinge support includes a hinge mechanism and a fixed screw for rotating and limiting the hinge mechanism. The axis of rotation of the hinge mechanism is horizontally arranged and perpendicular to the axis of rotation of the rotating component.

[0014] The beneficial effects of this invention are as follows: A movable rod is connected to a fixed rod via a connecting block, allowing the movable rod to be angle-adjustable relative to the fixed rod. The hemostatic pad at the bottom of the movable rod can also be angle-adjusted by rotating the support. This allows for clamping at the bottom in different directions with the fixed rod, achieving different angle adjustments without the need for motors or other equipment. Furthermore, the invention incorporates structures such as medicine bottles on the side of the connecting block. During clamping, the pressure from the hemostatic pad facilitates the flow of medication into the pad, further promoting wound hemostasis.

[0015] In this invention, when the fixed rod is used alone, it can directly press the hemostatic pad near the wound to achieve hemostasis. When the fixed rod is used in conjunction with the movable rod, the rotation angle of the movable rod relative to the fixed rod is adjusted by the rotating component, and the angle between the hemostatic pad at the bottom of the second mounting component and the movable rod is adjusted by the rotating support. This allows the amount of bleeding from the wound to be reduced by the squeezing between the fixed rod and the movable rod when they are close together.

[0016] As a preferred embodiment, the present invention incorporates a ratchet and tooth structure at the connecting block. This structure allows for the limiting and adjustment of the angle between the movable rod and the fixed rod. Specifically, the ratchet rotates within the connecting block under the drive of a rotating component. As the rotating component rotates, the ratchet causes the movable rod connected to it to move only in one direction (either closer to or further from the fixed rod). When the unlock button is pressed, the ratchet's longitudinal displacement separates it from the ratchet. The user can then rotate the knob to rotate the rotating component, thereby changing the angle between the movable rod and the fixed rod. Releasing the unlock button resets the ratchet under the action of the first spring, restoring the limiting rotation function of the ratchet and tooth structure.

[0017] As a preferred embodiment, to further adjust the rotation angle of the second mounting component at the bottom of the movable rod, a limiting rotating seat is provided on the upper part of the fixed rod, and a fixed support is provided on the second mounting component. A traction line between the limiting rotating seat and the fixed support pulls the second mounting component. When the limiting rotating seat rotates, the length of the traction line shortens, allowing the second mounting component to rotate based on the rotating support, thus adjusting the orientation of the hemostatic pad at the bottom of the second mounting component. This facilitates the formation of a compression-type hemostasis effect based on the fixed rod as a fulcrum. When adjusting the angle of the rotating support, the user pulls the sliding sleeve axially out, causing the rotating gear ring to disengage from the circular toothed groove inside the inner toothed groove. At this time, the second spring is compressed. When the sliding sleeve is rotated, the traction line will wrap around the surface of the winding groove to shorten its length, thereby adjusting the angle of the hemostatic pad at the bottom of the second mounting component. After the hemostatic pad angle is adjusted, the user releases the sliding sleeve, and under the action of the second spring, the sliding sleeve and the rotating gear ring return to their original positions.

[0018] As a preferred embodiment, stops connected to the sliding sleeve and the fixed rod are respectively provided at both ends of the second spring, which is beneficial for the compression and reset of the second spring, and also serves as a limiting function.

[0019] As a preferred solution, the medicine bottle is supported by a support frame. When the squeezing chamber at the bottom of the medicine bottle is subjected to squeezing force, the medicine can quickly enter the hemostatic pad, which is conducive to rapid hemostasis.

[0020] As a preferred option, the second one-way valve can prevent the medicine from flowing back; in order to avoid the formation of negative pressure inside the squeezing chamber when the hand is released, the first one-way valve is used to draw in external air into the medicine bottle, so that the medicine in the medicine bottle can smoothly enter the squeezing chamber.

[0021] As a preferred option, the medication is evenly distributed to the bottom of the hemostatic pad through a mesh-like outlet branch, so that the blood-absorbing material inside the hemostatic pad is not affected, while direct penetration to the bottom of the hemostatic pad can achieve the effect of uniform penetration.

[0022] As a preferred solution, a handle is provided on the connecting block for easy gripping. The handle is connected to the connecting block via a hinge support, enabling angle adjustment. This allows the entire hemostatic device to form an adjustment mechanism similar to a four-bar linkage, allowing the movable bar to achieve multi-angle adjustment relative to the fixed bar. It can also cooperate with the fixed bar in different directions to achieve a clamping effect at the bottom, thus realizing clamping adjustment at different angles. Attached Figure Description

[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] The structure of a hemostatic pad for compression in hepatobiliary surgery according to an embodiment of the present invention is as follows: Figure 1As shown, it includes a vertically arranged fixed rod 3, with a connecting block 2 fixedly connected to the upper part of the fixed rod 3. A diagonally arranged movable rod 4 is connected to the connecting block 2 via a rotating component 5. A first mounting component 301 and a second mounting component 402 are respectively connected to the bottom of the fixed rod 3 and the movable rod 4. A rotating support 401 connects the second mounting component 402 and the movable rod 4. The axes of the rotating support 401 and the rotating component 5 are parallel and both are arranged laterally. The central axes of the rotating support 401 and the rotating component 5 are both... Perpendicular to the length direction of the fixing rod 3, the bottom of the first mounting member 301 and the second mounting member 402 are respectively provided with liquid inlet chambers. The bottom of each liquid inlet chamber is connected to a hemostatic pad 6. Each liquid inlet chamber is provided with an inlet and an outlet. A medicine bottle 901 is installed on the connecting block 2. Two flexible branch tubes 903 are connected to the medicine bottle 901. The outlets of the two flexible branch tubes 903 are respectively connected to the inlets of the two liquid inlet chambers. The outlet is connected to the hemostatic pad 6 and is used to guide the medicine into the hemostatic pad 6. The top of the fixing rod 3 is connected to a handle 1 through a hinge support 101. The hinge support 101 includes a hinge mechanism and a fixing screw for rotating and limiting the hinge mechanism. The rotation axis of the hinge mechanism is horizontally set and perpendicular to the rotation axis of the rotating member 5.

[0027] like Figures 2 to 4 As shown, a limiting rotating seat 7 is provided at the position below the connecting block 2 on the fixed rod 3. The limiting rotating seat 7 includes an internal tooth groove 701 and a rotating tooth ring 702. The outer periphery of the internal tooth groove 701 is fixed inside the fixed rod 3, and the inner circumferential surface of the internal tooth groove 701 is provided with internal teeth. The outer periphery of the rotating tooth ring 702 is provided with external teeth that mesh with the internal teeth. A spring rod 704 is fixedly connected to the center of the internal tooth groove 701. A second spring 706 is sleeved on the spring rod 704. The spring rod 704 passes through the center of the rotating tooth ring 702. A sliding sleeve located outside the fixed rod 3 is fixedly connected to the rotating tooth ring 702. 703, the sliding sleeve 703 is concentrically sleeved on the outer periphery of the spring rod 704, one end of the second spring 706 is connected to the end of the spring rod 704 away from the rotating gear ring 702, and the other end of the second spring 706 is connected to the end of the sliding sleeve 703 near the rotating gear ring 702. The outer periphery of the end of the sliding sleeve 703 away from the rotating gear ring 702 is provided with an annular winding groove 705. The second mounting member 402 is provided with a fixed support 801, and a traction line 8 is connected to the fixed support 801. One end of the traction line 8 is connected to the fixed support 801, and the other end of the traction line 8 is wound in the winding groove 705. The bottom end of the inner tooth groove 701 is a closed end, and a connecting post 707 is fixed at the center of the closed end. The spring rod 704 is fixedly connected to the connecting post 707. The inner side of the sliding sleeve 703 near the end of the rotating tooth ring 702 is provided with an inner stop block 708, and the end of the spring rod 704 away from the rotating tooth ring 702 is provided with an outer stop block 709. The two ends of the second spring 706 are respectively connected to the inner stop block 708 and the outer stop block 709.

[0028] The connecting block 2 has an internal cavity, such as Figures 5 to 6 As shown, one end of the rotating component 5 is fixedly connected to a knob 505, and the other end is fixedly connected to a ratchet 502. The ratchet 502 is located inside the inner cavity of the connecting block 2, and the knob 505 is located outside the connecting block 2. An unlocking button 501 is provided on one side of the rotating component 5 on the connecting block 2. One end of the unlocking button 501 is located outside the connecting block 2, and the other end is connected to a ratchet 503 that cooperates with the ratchet 502. The ratchet 503 is located in the inner cavity. A spring post is fixedly connected between the unlocking button 501 and the ratchet 503. The diameter of the unlocking button 501 is larger than the diameter of the spring post. A first spring 504 is sleeved on the spring post. The first spring 504 is located between the outer surface of the connecting block 2 and the unlocking button 501.

[0029] A support frame 9 is installed on the side of the connecting block 2 away from the movable rod 4. The medicine bottle is installed inside the support frame 9. The bottom of the medicine bottle 901 has a squeezing chamber 902, and a flexible pipe is connected to the bottom of the squeezing chamber 902. Two flexible branch pipes 903 are connected in parallel at the outlet of the flexible pipe. A rubber sleeve 906 is fixedly fitted around the outer periphery of the squeezing chamber 902, and the rubber sleeve 906 is fixedly connected to the side of the connecting block 2. A first one-way valve 904 is provided at the inlet at the top of the medicine bottle 901, and a second one-way valve 905 is provided at the outlet at the bottom of the squeezing chamber 902. The first one-way valve 904 is used to allow air to enter the medicine bottle 901, and the second one-way valve 905 is used to allow liquid to exit through the flexible pipe.

[0030] Each hemostatic pad 6 has a drug inlet 601 at its top, which is sealed to the outlet of the inlet chamber via threads. Inside the hemostatic pad 6 is a drug distribution mesh made of medical plastic, comprising a main pipe and several outlet branches 602 connected in parallel with the main pipe. The main pipe is positioned upwards and located within the drug inlet 601. Each outlet branch 602 has a mesh structure with its outlet facing downwards, and the outlet branches 602 are evenly distributed at the bottom of the hemostatic pad 6.

[0031] like Figure 1 As shown, an embodiment of the hepatobiliary surgical wound compression hemostatic pad device of the present invention is designed with a longitudinally rotating handle 1, which allows the connecting block 2 to rotate a certain longitudinal angle, i.e., the front-to-back angle, based on the hinge support 101. This allows the bottom of the fixed rod 3 and the movable rod 4 to be inserted into the vicinity of the wound from the side or other directions. The hinge support 101 adopts a fixable structure. When the hinge support 101 is adjusted and fixed, the fixing screw is screwed into the axial part of the hinge support 101 to form a fixing effect. The fixing method can also be other methods, such as using a splined shaft.

[0032] The fixed rod 3 is fixed at the bottom of the connecting block 2 and is projected longitudinally onto the same extension line as the handle 1. The bottom is fixed with a hemostatic pad 6 by the first mounting part 301. When the fixed rod 3 is used alone, the hemostatic pad 6 can be pressed directly to the vicinity of the wound to form a hemostatic effect. When the fixed rod 3 is used in conjunction with the movable rod 4, the rotation angle of the movable rod 4 relative to the fixed rod 3 is adjusted by the rotating part 5, so that the bottom of the movable rod 4 is based on the hemostatic pad 6 fixed by the second mounting part 402. When the fixed rod 3 and the movable rod 4 are close together, the amount of bleeding from the wound is reduced by the squeezing between the fixed rod 3 and the movable rod 4.

[0033] In order to further adjust the specific rotation mechanism of the second mounting part 402 at the bottom of the movable rod 4, a limiting rotating seat 7 is provided on the upper part of the fixed rod 3, and a fixed support 801 is provided on the second mounting part 402. The fixed support 801 is pulled by the traction line 8 between the fixed support 801 and the limiting rotating seat 7. When the limiting rotating seat 7 rotates, the length of the traction line 8 is shortened, so that the second mounting part 402 rotates based on the rotating support 401, realizing the angle adjustment of the hemostatic pad 6 at the bottom of the second mounting part 402, which makes it easier to form a squeezing hemostatic effect based on the fixed rod 3 as the fulcrum.

[0034] Furthermore, such as Figure 2-3 As shown, to facilitate easy adjustment of the limiting mechanism, an internal toothed groove 701 is provided on the surface of the limiting rotating seat 7. The internal toothed groove 701 is fixed inside the fixed rod 3. When adjusting the angle of the rotating support 401, the user pulls the sliding sleeve 703 axially out, causing the rotating gear ring 702 to disengage from the ring-shaped toothed groove inside the internal toothed groove 701. At this time, the second spring 706 inside the sliding sleeve 703 is compressed. The sliding sleeve 703 is sleeved on the outside of the spring rod 704. When the sliding sleeve 703 is rotated, the spring rod 704 itself... The spring rod 704 does not rotate. It is located inside the sliding sleeve 703 and is only fixedly connected to the inner tooth groove 701 at its end. Therefore, when the sliding sleeve 703 rotates, the traction line 8 will wrap around the surface of the winding groove 705 to shorten its length and realize the angle adjustment of the hemostatic pad 6 at the bottom of the second mounting part 402. After the sliding sleeve 703 rotates a certain number of times, the user releases the sliding sleeve 703. Under the action of the second spring 706, the rotating tooth ring 702 returns to the inner side of the inner tooth groove 701, forming a rotation limit function.

[0035] Furthermore, such as Figure 5-6As shown, the rotating component 5 has a ratchet 502 inside the connecting block 2. The ratchet 502 rotates only inside the connecting block 2 under the drive of the rotating component 5. When the rotating component 5 rotates, the movable rod 4 connected to the rotating component 5 will only move towards the fixed rod 3 due to the action of the ratchet 503. When the unlocking button 501 is pressed, the ratchet 503 is longitudinally displaced and separated from the ratchet 502. At this time, the user can unlock the rotating component 5 and adjust the angle between the movable rod 4 and the fixed rod 3 by rotating the knob 505. A first spring 504 is provided between the unlocking button 501 and the connecting block 2. When the unlocking button 501 is pressed, the first spring 504 will be compressed, and the ratchet 503 will be misaligned with the ratchet 502. After releasing the button, the first spring 504 will return to its original position, driving the ratchet 503 to reset and restoring the limiting rotation function of the ratchet.

[0036] like Figure 7-9 As shown, a support frame 9 is provided on the left side of the connecting block 2, and a medicine bottle 901 is installed inside the support frame 9. The medicine bottle 901 is provided with a squeezing chamber 902. The squeezing chamber 902 is supplied with medicine through a flexible pipe via two flexible branch pipes 903 to the first mounting member 301 and the second mounting member 402 respectively. This allows the hemostatic medicine to be supplied to the medicine chamber through the first mounting member 301 and the second mounting member 402, and then enter the hemostatic pad 6. Finally, the medicine is dispersed and evenly output to the bottom of the hemostatic pad 6 through the mesh-like outlet branch pipe 602, achieving the effect of synchronous delivery of medicine during squeezing and uniform penetration into the wound surface.

[0037] Furthermore, a first one-way valve 904 is provided at the top of the medicine bottle 901, and a second one-way valve 905 is provided at the bottom of the squeezing chamber 902. When the operator needs to dispense the medicine, he presses the rubber sleeve 906, which causes the squeezing chamber 902 to dispense the internal medicine through the second one-way valve 905 into the flexible pipe, thereby increasing the flow rate. When the operator releases the pressure, the negative pressure inside the squeezing chamber 902 will prevent the medicine from entering. To avoid this, the first one-way valve 904 will draw in external air towards the negative pressure inside the medicine bottle 901, allowing the internal medicine to smoothly enter the squeezing chamber 902.

[0038] Furthermore, two flexible branch pipes 903 are connected in parallel at the lower part of the flexible pipe. When needed, they can extend downwards close to the surfaces of the fixed rod 3 and the movable rod 4 to achieve the effect of moving synchronously with the fixed rod 3 and the movable rod 4.

[0039] In use, after adjusting the hinge support 101, the user fixes the handle 1 and connecting block 2. Then, the user adjusts the rotating component 5 a second time, ensuring the gap between the fixed rod 3 and the movable rod 4 roughly corresponds to the wound surface. First, the fixed rod 3 is pressed near the wound surface, and the movable rod 4 is continuously adjusted from the other side to apply pressure to the other side of the wound surface until it is properly adjusted via the limiting rotating seat 7 and the rotating component 5. Finally, the rubber sleeve 906 is pressed, allowing the hemostatic solution inside the medicine bottle 901 to evenly penetrate to the bottom of the hemostatic pad 6. Under the mutual pressure, the hemostatic pad 6 evenly distributes the solution, achieving precise hemostasis. The hemostatic pad 6 can be made of hemostatic cotton or other medical pad-like structures with penetrating properties.

Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed.
