Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a femoral artery compression hemostat after hepatic artery embolization intervention. Background Technology

[0002] Hepatic artery embolization interventional surgery requires arterial puncture at the corresponding location on the patient's body surface. The purpose is to block the blood supply to liver cancer. The basic principle of the surgery is to inject various embolic agents into the hepatic artery to block the arterial blood supply to the tumor, causing it to become ischemic and necrotic. To prevent massive arterial bleeding after the operation, a special femoral artery compression hemostat is needed to perform physical compression hemostasis.

[0003] In existing technology, femoral artery compression hemostatic devices mainly consist of a compression component and a fixing component for securing the compression component. The fixing component includes a connecting plate positioned on the lower side of the patient's leg and a strap connecting the compression component body and the connecting plate. The compression head and the connecting strap are positioned offset. During operation, the middle part of the compression component body and the connecting plate are first connected and locked together by the strap to fix the compression component body, aligning the compression head with the puncture site. Then, by moving the compression head downward relative to the entire compression component, downward pressure is generated to achieve hemostasis. Based on this, the entire compression component and the strap actually form a 90° angle to ensure that the compression head can apply all downward pressure to the puncture point. This raises a problem: since the compression hemostasis process involves first roughly fixing the entire compression component, and then using the compression head to further compress the puncture point for hemostasis, the end of the compression head may tilt at a certain angle relative to the bandage during this process. Although medical staff can adjust the bandage to correct the angle, this is basically a flexible adjustment at the end closest to the skin. Since the relative positions of the bandage and the compression head have changed, the angle between them is unlikely to automatically return to the standard 90° due to fine-tuning. Therefore, in order to avoid the problem of subsequent compression hemostasis failure caused by the compression head tilting due to the fixed compression angle, this application urgently needs to redesign the compression hemostasis device. Summary of the Invention

[0004] This application proposes a femoral artery compression hemostat after hepatic artery embolization intervention, which has the advantage of assisting in the correction of the compression angle, in order to solve the problem of pressure relief caused by the tilting of the compression angle due to compression in the prior art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a femoral artery compression hemostat after hepatic artery embolization intervention, comprising a main body, a compression component disposed on the left side inside the main body, an upper pressure plate hinged to the right side of the bottom of the main body, a lower pressure plate disposed below the main body, rotating blocks rotatably mounted on both the front and rear sides of the main body, a fixing frame fixedly connected to the end of the rotating block, a locking strap fixedly connected to the outer side of the lower pressure plate, the locking strap being wrapped around the inside of the fixing frame, adapter openings provided on both the front and rear sides of the lower pressure plate, and positioning components disposed on both the front and rear sides of the main body; The positioning component includes two sets of fixed posts fixedly connected to the surface of the main body. A positioning plate is rotatably mounted on the outer surface of the fixed posts. A connecting plate is detachably mounted on the front of the positioning plate. An adapter strip is fixedly connected to the bottom of the connecting plate. The bottom of the adapter strip is adapted to be inserted into the adapter port. The centerline of the positioning plate coincides with the axis of the rotating block.

[0006] Preferably, a placement cavity is provided on the left side inside the main body, the compression assembly includes a lead screw installed inside the placement cavity, a positioning column is fixedly installed on the inner wall of the placement cavity, a moving head is slidably installed on the outer surface of the positioning column, the positioning column is threadedly connected to the moving head, a compression head is fixedly connected to the bottom of the moving head, and a Holstein pad is fitted on the outer surface of the compression head.

[0007] Preferably, the left side of the main body has a heat dissipation hole communicating with the placement cavity, the upper pressure plate and the lower pressure plate are both arc-shaped, the inner side of the upper pressure plate has a number of equally spaced air-permeable pads I fixedly attached, and the inner side of the lower pressure plate has a number of equally spaced air-permeable pads II fixedly attached.

[0008] Preferably, the main body has symmetrically distributed indicator scales on both the front and rear sides, and indicator pins are fixedly connected to both the left and right sides of the fixed frame.

[0009] Preferably, a fixed shaft is fixedly installed inside the fixed frame, and a sleeve is movably sleeved on the outer surface of the fixed shaft. The locking band is wrapped around the outer surface of the sleeve, and the locking band can drive the sleeve to rotate.

[0010] Preferably, a screw is fixedly connected to the side of the connecting plate that contacts the positioning plate, the screw extends to the other side of the positioning plate, and a nut is installed on the outer surface of the screw, and the connecting plate and the positioning plate are fixedly locked by the nut.

[0011] Preferably, the positioning plate has two sets of positioning grooves on its front side, and the connecting plate has two sets of positioning protrusions fixedly connected to the side facing the positioning plate, the positioning protrusions being adapted to the positioning grooves.

[0012] Preferably, the angle between the connecting plate and the main body is 90°, and the locking band can drive the fixing frame and the rotating block to rotate freely relative to the main body when it is taut.

[0013] The beneficial effects of this invention are as follows: I. Automatic correction and precise maintenance of the pressure angle This application effectively solves the problem of pressure angle deviation caused by the tilting of the main body during the downward pressing of traditional compression hemostats by adding a positioning component and using a rotating block connection between the fixing frame and the main body. When the compression component extends downward to apply pressure to the femoral artery puncture point, the left side of the main body will rise axially with the hinge of the upper pressure plate as the pivot point. At this time, the locking band is fixed only by its own tension and will not twist or deform due to the tilting of the main body. On this basis, the positioning plate, connecting plate and adapter strip in the positioning component cooperate with each other. The adapter strip can be inserted into the adapter port on the lower pressure plate to form a rigid connection between the main body and the lower pressure plate, balancing the upward lifting force generated by the compression on the left side of the main body to the right, thereby forcing the pressure angle of the compression component back to the vertical downward state. This design ensures that the compression force always acts perpendicularly on the puncture point, avoiding the problem of compression force removal or hemostasis failure caused by angle deviation, and significantly improving the reliability and effectiveness of femoral artery compression hemostasis after interventional procedures.

[0014] 2. The flexible rotating connection between the locking band and the main body enhances the stability of the fixation. This application abandons the rigid connection between the locking band and the main body in traditional hemostats, instead using a rotating block to achieve relative rotation between the fixed frame and the main body. When the main body tilts during compression, the locking band remains vertically taut, and its pressure direction does not change. It adapts to the angle change of the main body only through the natural adaptation of its own tension, avoiding the decrease in locking force caused by lateral twisting or bending. At the same time, the locking band wraps around the outer surface of the sleeve, and can drive the sleeve to rotate when passing through the fixed frame, greatly reducing frictional resistance and making the tightening operation of the locking band more effortless and smooth. This flexible rotating connection and the rigid positioning component work together—the flexible locking is responsible for stable fixation, and the rigid positioning is responsible for angle correction. The two have a clear division of labor, which not only ensures a firm fit between the hemostat and the patient's leg, but also provides a structural basis for precise adjustment of the pressure angle.

[0015] III. Visual Angle Indication and Comfort Optimization Design This application features symmetrically distributed indicator scales on both the front and rear sides of the main body. An indicator needle is fixed to the fixing frame. When the main body tilts due to pressure, the fixing frame rotates relative to the main body, and the indicator needle reading reflects the tilt angle between the locking strap and the main body in real time, i.e., the degree of offset of the pressure applied by the compression component. Medical personnel can intuitively determine whether the positioning component needs to be activated for angle correction based on the indicator needle reading, making the operation more scientific, precise, and quantifiable. Furthermore, both the upper and lower pressure plates are designed with an arc-shaped structure, better conforming to the curve of the human leg. Multiple sets of equally spaced breathable pads (one and two) are fixedly attached to their inner sides, effectively reducing the sealing area between the pressure plates and the body surface, increasing air circulation, and mitigating the stuffiness and pressure sores risk during prolonged wear. A heat dissipation hole communicating with the placement cavity is provided on the left side of the main body, allowing heat dissipation for drive components such as the lead screw, extending the working life of the compression component. In summary, this application achieves significant improvements in the accuracy, stability, ease of operation, and patient comfort of pressure hemostasis. Attached Figure Description

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] Please see Figures 1-9 This embodiment discloses a femoral artery compression hemostat after hepatic artery embolization intervention, including a main body 1. A compression component 4 is provided on the left side inside the main body 1. An upper pressure plate 5 is hinged to the right side of the bottom of the main body 1. A lower pressure plate 8 is also provided below the main body 1. Rotating blocks 16 are rotatably installed on both the front and rear sides of the main body 1. A fixing frame 12 is fixedly connected to the end of the rotating block 16. A locking strap 15 is fixedly connected to the outside of the lower pressure plate 8. The locking strap 15 is wrapped around the inside of the fixing frame 12. Adaptor ports 10 are provided on both the front and rear sides of the lower pressure plate 8. Positioning components 7 are provided on both the front and rear sides of the main body 1. The positioning component 7 includes two sets of fixing posts 71 fixedly connected to the surface of the main body 1. A positioning plate 72 is rotatably mounted on the outer surface of the fixing posts 71. A connecting plate 73 is detachably mounted on the front of the positioning plate 72. An adapter strip 74 is fixedly connected to the bottom of the connecting plate 73. The bottom of the adapter strip 74 is adapted to be inserted into the adapter port 10. The center line of the positioning plate 72 coincides with the axis of the rotating block 16. This hemostat has been redesigned, incorporating a positioning component 7 to synchronously adjust the overall tilt angle of the main body 1. This ensures that the downward pressure angle of the compression component 4 on the patient's femoral artery puncture point remains stable and vertically downward, effectively performing compression hemostasis. To achieve this, the hemostat is equipped with two sets of positioning components 7 rotatably mounted on the front and rear sides of the main body 1, perpendicular to the patient's leg. These components are responsible for adjusting the main body 1 after compression fixation, correcting the angle between the compression component 4 and the locking band 15 after compression extension. This ensures that the pressure angle of the fixed compression component 4 on the femoral artery puncture point is controlled within a range that does not affect the compression force. The lower pressure plate 8 is located directly below the main body 1. It is locked and fixed to the main body 1 by locking band 15. When the compression component 4 extends downward, the left side of the main body 1 will rotate upward with the hinge of the upper pressure plate 5 and the main body 1 as the axis of rotation. At this time, it can be fixedly connected to the positioning plate 72 by connecting plate 73. The positioning plate 72 is parallel to the main body 1, and the positioning plate 72 and connecting plate 73 drive the adapter strip 74 to rotate downward and be inserted into the adapter port 10. This makes the lower pressure plate 8 fixed to the main body 1 as a whole by positioning component 7. At this time, the rigidly set positioning component 7 balances the pressure and displacement from the left side of the heat dissipation hole 3 to the right, so that the pressure angle of the compression component 4 can be corrected and maintain the normal compression hemostasis function of the puncture point.

[0021] Then, this device improves the connection method between the fixed frame 12 and the main body 1, replacing the traditional fixed locking with the mutual rotation connection between the rotating block 16 and the main body 1. When the pressure component 4 starts to extend, the main body 1 rotates around the top hinge point of the upper pressure plate 5. The rotating installation of the rotating block 16 ensures that when the main body 1 tilts, the locking band 15 will only adapt through its own tension, and will not tilt laterally, effectively ensuring the locking function of the locking band 15. Therefore, the locking band 15 only needs to maintain the locking force, and the direction of the pressure it generates remains unchanged. The change in the magnitude of the pressure will not affect the overall locking effect. The positioning component 7 is located on the outside of the locking band 15, and uses rigid positioning to compensate for the positioning and return function that the flexible locking locking band 15 cannot complete.

[0022] In this embodiment, a placement cavity 2 is provided on the left side inside the main body 1. The compression component 4 includes a lead screw 41 installed inside the placement cavity 2. A positioning column 42 is fixedly installed on the inner wall of the placement cavity 2. A moving head 43 is slidably installed on the outer surface of the positioning column 42. The positioning column 42 and the moving head 43 are threadedly connected. A compression head 44 is fixedly connected to the bottom of the moving head 43. A Hess pad 45 is fitted on the outer surface of the compression head 44. like Figure 2As shown, the compression component 4 is located in the inner cavity of the placement cavity 2. The left side of the main body 1 has a heat dissipation hole 3, which is connected to the placement cavity 2 and is used to dissipate heat from the lead screw 41. The lead screw 41 rotates, thereby driving the moving head 43, the compression head 44 and the Holster pad 45 to move downward. Under the guidance of the positioning column 42, a stable compression hemostasis operation is performed. The drive module of the compression component 4 is located in the inner cavity of the placement cavity 2. In order to reduce the impact of heat generation on the lead screw 41, a heat dissipation hole 3 is provided on the left side of the main body 1, which is connected to the placement cavity 2, to facilitate heat dissipation of the lead screw 41.

[0023] In this embodiment, the left side of the main body 1 is provided with a heat dissipation hole 3 that communicates with the placement cavity 2. The upper pressure plate 5 and the lower pressure plate 8 are both arc-shaped. Multiple sets of equally spaced breathable pads 6 are fixedly attached to the inner side of the upper pressure plate 5, and multiple sets of equally spaced breathable pads 9 are fixedly attached to the inner side of the lower pressure plate 8. like Figure 2 As shown, the upper pressure plate 5 and the lower pressure plate 8, which are used to directly contact the patient's body surface, reduce the area sealed by the upper pressure plate 5 and the lower pressure plate 8 through multiple sets of gaps formed by the first breathable pad 6 and the second breathable pad 9, thereby increasing the breathability.

[0024] In this embodiment, the front and rear sides of the main body 1 are provided with indicator scales 11 that are symmetrically distributed from left to right, and the left and right sides of the fixed frame 12 are fixedly connected with indicator pins 13. like Figure 2 As shown, the indicator scale 11 is used in conjunction with the indicator needle 13 to indicate the tilt angle of the fixing frame 12 relative to the main body 1, that is, the tilt angle of the locking band 15 relative to the main body 1. This tilt angle can reflect the offset angle of the pressure component 4 applying downward pressure to the puncture point, thereby facilitating the observation of the tilt degree of the pressure component 4 and facilitating subsequent adjustment by the positioning component 7.

[0025] In this embodiment, a fixed shaft is fixedly installed inside the fixed frame 12, and a sleeve 14 is movably sleeved on the outer surface of the fixed shaft. A locking band 15 is wrapped around the outer surface of the sleeve 14, and the locking band 15 can drive the sleeve 14 to rotate. like Figures 4-6 As shown, the fixing frame 12 wraps around and flips the locking band 15 so that the locking band 15 is fixed in the opposite direction by Velcro, which is beneficial to locking the patient's leg between the pressure plate 8 and the main body 1 and fixing the entire hemostat. When the locking band 15 passes through the fixing frame 12, its surface will drive the sleeve 14 to rotate, reducing frictional resistance.

[0026] In this embodiment, a screw 76 is fixedly connected to the side of the connecting plate 73 that contacts the positioning plate 72. The screw 76 extends to the other side of the positioning plate 72. A nut 77 is threaded on the outer surface of the screw 76, and the connecting plate 73 and the positioning plate 72 are fixedly locked by the nut 77. like Figures 1-2As shown, the positioning plate 72 is rotatably connected to the surface of the main body 1 via the fixing post 71. It is parallel to the main body 1 and can serve as a marker to correct the angle of the main body 1 and the compression component 4 relative to the standard pressure applied at the puncture point. The connecting plate 73 is fixed by screws 76 and nuts 77 and can be disassembled. When the pressure offset angle of the compression component 4 is small, the connecting plate 73 can be omitted for correction.

[0027] In this embodiment, the front of the positioning plate 72 is provided with two sets of positioning grooves 78, and the connecting plate 73 is fixedly connected to two sets of positioning protrusions 75 on the side facing the positioning plate 72. The positioning protrusions 75 are adapted to the positioning grooves 78. like Figure 1 and Figure 5 As shown, the positioning protrusion 75 is used to insert into the positioning groove 78 to assist in positioning and locking the connecting plate 73 during installation.

[0028] In this embodiment, the angle between the connecting plate 73 and the main body 1 is 90°, and the locking band 15 can drive the fixing frame 12 and the rotating block 16 to rotate freely relative to the main body 1 when it is taut. like Figures 1-3 As shown, the angle between the connecting plate 73 and the main body 1 is 90°. After the locking band 15 is locked, its position is basically not adjusted. The tightened locking band 15 is used to adhere tightly to the patient's body surface and maintain the stability of the main body 1 after it is fixed. Therefore, this hemostat uses relative rotation for the connection between the locking band 15 and the main body 1. The purpose is to prevent the locking band 15 from deforming due to tilting when the main body 1 tilts as a whole, thus affecting the fixation and adhesion effect.

[0029] Working principle: When using this hemostat, first determine the patient's femoral artery puncture point and ensure that the compression component 4 is aligned with the puncture point. Then, pre-position the lower pressure plate 8 on the patient's leg and ensure that it is directly opposite the bottom of the main body 1. After placing the bottom of the compression component 4 against the patient's femoral artery puncture point, the upper pressure plate 5 is placed downward against the patient's leg. Then, pass the locking strap 15 through the inside of the fixing frame 12 and wrap it around the outer surface of the sleeve 14. Pull the locking strap 15 downward and lock it with the Velcro on the inside of the locking strap 15. At this time, the compression component 4, the upper pressure plate 5 and the lower pressure plate 8 are all in contact with the patient's body surface with a certain pressure, completing the initial fixation. Then, the Horst pad 45 is placed on the outer surface of the compression head 44, and the compression assembly 4 is activated. The screw 41 rotates, causing the moving head 43, compression head 44, and Horst pad 45 to move downwards continuously, applying pressure to the patient's femoral artery puncture site to perform compression hemostasis. Figure 2 , Figure 3As shown, when the left side of the main body 1 presses down on the puncture point by the pressure component 4, it will rise up relative to the upper pressure plate 5 and the lower pressure plate 8. At this time, the left side of the main body 1 will rotate relative to the rotating block 16 and generate a moving angle θ with the locking band 15. The fixed frame 12 will drive the indicator needle 13 to rotate relative to the main body 1 and change the reading of the indicator needle 13 on the indicator scale 11. Finally, when θ is too large, the connecting plate 73 is installed on the front of the positioning plate 72 using screws 76 and nuts 77, and positioning is completed by positioning protrusions 75 and positioning grooves 78. Then, the position of the main body 1 is adjusted so that the angle between the connecting plate 73, the positioning plate 72 and the tightened locking band 15 is close to 90°. Then, the positioning plate 72, the connecting plate 73 and the adapter strip 74 are rotated as a whole, so that the adapter strip 74 is inserted into the adapter port 10 by rotation. The positioning plate 72, the connecting plate 73, the adapter strip 74 and the lower pressure plate 8 form a... The pressure on the left side of the main body 1 is distributed to the right side of the upper pressure plate 5 through the positioning plate 72 and the connecting plate 73. During this process, the main body 1 rotates relative to the rotating block 16 through the overall adjustment of the positioning component 7 without changing the angle of the tightening band 15, so that the tightening band 15 always remains vertically taut. After adjustment, the fixing frame 12 drives the indicator needle 13 to return to the center, and the indicator needle 13 points to the horizontal center reading of the indicator scale 11, so that the pressure angle of the compression component 4 on the puncture point returns to the center.
