[0047] During use of the blood vessel puncture port sealing device with sound and color prompts of the present invention, the end close to the operator is the proximal end, and the end away from the operator is the distal end.

[0048] The present invention aims to solve the problem that the locking timing of current blood vessel occluding instruments is difficult to determine or easy to misjudge during use, and provides a blood vessel puncture port occluding device with sound and color prompts.

[0049] The blood vessel puncture port sealing device with sound and color prompts according to the embodiment of the present invention is as follows: Figure 1-6As shown, it includes: a sealing part 1, which is connected to a suture 6 and is used to seal the blood vessel puncture; a locking part 2, which is used to lock the sealing part 1 at the blood vessel puncture; an introduction part 3, which has an inner cavity for accommodating at least part of the sealing part 1 and the locking part 2, and is used to transport the sealing part 1 to the blood vessel puncture; a feedback part 5, which is used at least to issue a sound prompt when the locking part 2 reaches a set position (for example, a position suitable for locking the locking part 2 and the sealing part 1); a handle 4, which is connected to the handle 4 and The introduction part 3 is connected, the handle 4 has an inner cavity, and the feedback part 5 is assembled in the handle 4; the feedback part 5 includes a spring box 51, a wire pressing buckle 52 and a marking pressing piece 53, the spring box 51 has a cavity for accommodating at least part of the wire pressing buckle 52, and an outer wall of one end of the spring box 51 is provided with a spring piece 5121; the wire pressing buckle 52 has a wire pressing column 521, the wire pressing column 521 is connected to the end of the suture 6 away from the blocking part 1, and the wire pressing column 521 is in clearance with the spring box 51 and penetrates the spring box 51; the marking pressing piece 53 is L-shaped, and has a first pressing piece 5 31 and a second pressing piece 532; the first pressing piece 531 is detachably connected to the pressing post 521; the second pressing piece 532 is arranged parallel to the axial direction of the pressing post 521, and a protrusion 5321 is arranged on the second pressing piece 532, and the protrusion 5321 is configured to deform the spring piece 5121 and emit a sound prompt when the spring piece 5121 slides relative to the spring box 51; the second pressing piece 532 is also provided with a color patch 5322, and the color patch 5322 has at least a first indicating color and a second indicating color (preferably, the first indicating color and The second indicating color is arranged along the axial direction), the color patch 5322 and the protrusion 5321 are arranged on opposite surfaces of the second pressing plate 532 (for example, the protrusion 5321 is arranged on the lower surface of the second pressing plate 532 close to the spring 5121, and the color patch 5322 is arranged on the upper surface of the second pressing plate 532 away from the spring 5121); an observation window 41 is arranged at the position of the handle 4 corresponding to the color patch 5322 (preferably, the observation window 41 is transparent and hollowed out to facilitate observation of the color change of the color patch 5322).

[0050] Among them, the setting of the protrusion 5321 on the marking pressing sheet 53 and the spring sheet 5121 on the outer wall of the spring box 51 is such that when the wire pressing column 521 and the marking pressing sheet 53 (protrusion 5321) slide relative to the spring box 51 until the protrusion 5321 contacts the spring sheet 5121 and the protrusion 5321 squeezes the spring sheet 5121, the spring sheet 5121 can be deformed and emit a sound prompt, and the operator can judge the relative movement distance between the wire pressing column 521 and the spring box 51 based on the sound prompt. This is because the wire pressing post 521 is connected to the end of the suture 6 away from the occluding portion 1. During the movement of the wire pressing post 521, the suture 6 is also subjected to force, causing the portion of the occluding portion 1 located outside the blood vessel puncture port (hereinafter, the component of the occluding portion 1 located outside the blood vessel puncture port will be referred to as the external fixing member) to move relative to the introduction portion 3. Therefore, the operator can effectively infer the position of the external fixing member in the human body, and then the operator can better determine the locking timing of the sealing material, which helps to solve or improve the problem of unsatisfactory sealing effect on the blood vessel puncture port caused by the difficulty in determining or easy misjudgment of the locking timing of the existing blood vessel occluding device during use.

[0051] The arrangement of the observation window 41 and the color patch 5322 ensures that when the wire pressing post 521 slides relative to the spring box 51, the color of the color patch 5322 observed at the observation window 41 will change, and the operator can use the color observed at the observation window 41 to assist in determining the position of the blood vessel puncture port sealing device (sealing part 1) with sound and color prompts of the present invention in the human body and determine the locking timing of the sealing part 1.

[0052] Preferably, the spring piece 5121 as a whole can be made of a stainless steel sheet (which can be arched) with a thickness of 0.04mm-0.06mm (for example, 0.04mm, 0.05mm or 0.06mm), and it will deform under force and make a "click" or "snap" sound. When the protrusion 5321 presses over the spring piece 5121, the spring piece 5121 is flattened and makes a sound; when the protrusion 5321 is removed, the spring piece 5121 arches and resets itself, also making a sound. Preferably, the blood vessel puncture port sealing device with sound and color prompts of the present invention can be configured as needed so that when the protrusion 5321 in the marking pressing sheet 53 presses the spring sheet 5121 so that the spring sheet 5121 is deformed and makes a sound, or when the protrusion 5321 of the marking pressing sheet 53 leaves the spring sheet 5121 so that the spring sheet 5121 returns to its original state and makes a sound, the sealing part 1 and the locking part 2 are just in a position where the sealing part 1 can seal the blood vessel puncture port by operating the locking part 2, so that the operator can determine the locking timing of the sealing part 1 and ensure the sealing effect of the blood vessel puncture port.

[0053] In a preferred embodiment of the blood vessel puncture port sealing device with sound and color prompts of the embodiment of the present invention, the wire pressing post 521 has a suture hole 5211 extending in the axial direction, and the end of the suture 6 away from the sealing part 1 is fixed at the suture hole 5211; the spring box 51 includes a box body 512 and a spring coil arranged in the box body 512 (not shown in the figure; for example, the spring coil is coaxially arranged with the box body 512, and the spring coil can be in the shape of a hollow column, attached to the inner wall of the box body 512, and has a cavity for accommodating the wire pressing post 521), the inner diameter of the spring coil is adapted to the outer diameter of the wire pressing post 521, and the spring coil is configured to expand and contract when the wire pressing post 521 slides relative to the spring box 51. Among them, the setting of the spring coil allows it to provide certain feedback to the operator, avoid or reduce the situation that the operator is not easy to determine the relative displacement of the wire pressing post 521 relative to the spring box 51 during the operation, and then it is difficult to determine the position of the sealing part 1 in the body, which helps the operator to determine the locking time of the sealing part 1 and ensure the sealing effect of the blood vessel puncture port.

[0054] In a preferred embodiment of the blood vessel puncture port sealing device with sound and color prompts of the embodiment of the present invention, a connecting groove 5212 is provided on the wire pressing column 521, and a card platform 5311 is provided on the first pressing plate 531, and the card platform 5311 is adapted to the connecting groove 5212; an installation groove 5122 is provided on the outer wall of the spring box 51, and the spring sheet 5121 is installed in the installation groove 5122, and the spring sheet 5121 is arched; the protrusion 5321 protrudes from the plane where the second pressing plate 532 is located toward the outer wall of the spring box 51. Among them, the setting of the connecting groove 5212 and the card table 5311 can conveniently realize the assembly of the first pressing plate 531 and the wire pressing column 521; the setting of the installation groove 5122 helps to avoid that the protrusion 5321 will not act on the outer wall of the spring box 51 before the marking pressing plate 53 moves to the corresponding position of the spring piece 5121, thereby avoiding or reducing the operator's misjudgment of the sound prompt due to the sound made by the protrusion 5321 acting on the outer wall of the spring box 51; by making the spring piece 5121 arched, it helps to make the protrusion 5321 contact with the spring piece 5121, and can more easily act on the spring piece 5121, so that the elastic deformation produces a sound prompt, thereby improving the sensitivity of the sound prompt.

[0055] In a preferred embodiment of the blood vessel puncture port sealing device with sound and color prompts of the embodiment of the present invention, the sealing portion 1 includes an anchor sheet 11 and a sealing sheet 12 (the sealing sheet 12 can be used as an external fixing part of the sealing portion 1, and is used outside the blood vessel in conjunction with the anchor sheet 11 located inside the blood vessel to seal the blood vessel puncture port), and the anchor sheet 11 and the sealing sheet 12 are connected by suture 6; the anchor sheet 11 is configured to be able to enter the blood vessel through the blood vessel puncture port in a first form, and to be able to seal at the blood vessel puncture port in a second form; the sealing sheet 12 is configured to be able to seal the blood vessel puncture port outside the blood vessel when the suture 6 is tightened. Among them, the arrangement of the anchor sheet 11 can adjust the relative angle or position relationship between the anchor sheet 11 and the blood vessel puncture port as needed, so as to transport it into the blood vessel or seal it at the position corresponding to the blood vessel puncture port in the blood vessel. The "first state" and "second state" of the anchor sheet 11 do not refer to two states before and after the overall shape or outer contour of the anchor sheet 11 changes, but refer to two states before and after the relative position or angle between the anchor sheet 11 and the blood vessel puncture port (or blood vessel) changes.

[0056] Preferably, refer to Figure 7 The structure of the anchor sheet 11 is as follows: the anchor sheet 11 is an elliptical sheet with two ends contracted (the two ends of the long axis of the ellipse are contracted), the anchor sheet 11 is provided with two thread holes, the two thread holes are eccentrically arranged (the two thread holes are arranged at positions other than the center of the anchor sheet 11; the two thread holes can be symmetrically arranged about the axis of the long axis direction), and the suture 6 passes through the two thread holes. More preferably, the material of the anchor sheet 11 can be PLGA, and its degradation period is 3-6 months.

[0057] Preferably, the plugging sheet 12 may be made of collagen sheet material, and one or more groups of through holes may be provided on the plugging sheet 12 (each group of through holes may include two through holes, and the through holes are provided in the thickness direction of the plugging sheet 12; when multiple groups of through holes are provided on the plugging sheet 12, the multiple groups of through holes are provided along the axis direction of the suture 6), and the suture 6 passes through one or more groups of through holes in sequence and then exits. The above-mentioned setting of the plugging sheet 12 enables the plugging sheet 12 to be compressed (folded) when a force is applied to the plugging sheet 12 along the axis direction of the suture 6, which helps to better achieve the plugging of the blood vessel puncture.

[0058] In a preferred embodiment of the blood vessel puncture port sealing device with sound and color prompts according to the embodiment of the present invention, as Figure 7As shown, the locking portion 2 includes a locking knot 21, a first locking piece 22, a driving tube 23 and a second locking piece 24 which are arranged in sequence, and the driving tube 23 is limited between the first locking piece 22 and the second locking piece 24; the locking knot 21 is arranged between the blocking piece 12 and the first locking piece 22, and the locking knot 21 is a slipknot, which is used to slide along the suture 6 to adjust the suture 6 between the anchor piece 11 and the blocking piece 12 (adjust the length of the suture 6 between the anchor piece 11 and the blocking piece 12 of the suture 6); the first locking piece 22 and the second locking piece 24 are respectively interference fit with the suture 6, and the first locking piece 22 is configured to compress the blocking piece 12 in a direction close to the anchor piece 11 when the driving force it receives is greater than a set value; the suture 6 is arranged to pass through the driving tube 23, and the driving tube 23 is used to drive the first locking piece 22.

[0059] Among them, by arranging the driving tube 23 between the first locking member 22 and the second locking member 24, the driving tube 23 can be easily limited, avoiding or reducing the driving tube 23 from sliding repeatedly during the use of the blood vessel puncture port sealing device with sound and color prompts of the present invention, which affects the sealing effect of the blood vessel puncture port. The "locking knot 21" can be formed by tying the suture 6 at the position of the anchor plate 11 away from one end of the sealing plate 12 and the suture 6 at the position after passing through the sealing plate 12 (the present invention does not limit the specific structure of the locking knot 21, and it is sufficient to realize that the locking knot 21 can slide along the suture 6; the locking knot 21 and the first locking member 22 are used in combination to more firmly lock the sealing plate 12 and the anchor plate 11 at the blood vessel puncture port to ensure the sealing effect of the blood vessel puncture port).

[0060] Preferably, the driving tube 23 is in the shape of a hollow tube with both ends open, the inner diameter of the driving tube 23 is larger than the diameter of the suture 6, and the axial dimension of the driving tube 23 is larger than the first locking piece 22 (in addition, the inner diameter of the driving tube 23 is smaller than the outer diameter of the first locking piece 22 to prevent the first locking piece 22 from entering the driving tube 23 when the driving tube 23 abuts against the first locking piece 22 and moves toward the anchor plate 11, thereby affecting the driving effect of the first locking piece 22). The above arrangement allows the operator to operate the driving tube 23 to move along the suture 6 with little resistance and is easy to hold. Therefore, when the first locking piece 22 needs to be operated to lock the blocking piece 12 at the vascular puncture port, the driving tube 23 can be operated to cause the driving tube 23 to act on the first locking piece 22 to achieve the locking of the blocking piece 12 by the first locking piece 22, which is more convenient to operate.

[0061] More preferably, the first locking member 22 and the second locking member 24 respectively have threading holes, the aperture of the threading hole is interference fit with the outer diameter of the suture 6, and the friction force between the two can be about 0.15N-0.3N (for example, 0.15N, 0.2N, 0.25N or 0.3N), so as to help keep both of them still under normal conditions; at the same time, the driving tube 23 can also push the first locking member 22 (and / or the second locking member 24) to move; the suture 6 can use polyester suture 6 with specification 1 (wire diameter of 0.400-0.499mm); the material of the first locking member 22 and the second locking member 24 can be stainless steel 316.

[0062] In a preferred embodiment of the blood vessel puncture port sealing device with sound and color prompts according to the embodiment of the present invention, as Figure 8-10 As shown, the introduction part 3 includes a fixed sheath 31, an outer catheter 32 and an inner catheter 33; one end of the fixed sheath 31 is pre-placed in the blood vessel, and has an inner cavity allowing the outer catheter 32 to pass through; the outer catheter 32 is slidably assembled with the inner catheter 33, the outer catheter 32 has a cavity for accommodating the inner catheter 33, and the proximal end of the outer catheter 32 is provided with an outer tube assembly 321; the inner catheter 33 has a cavity for accommodating at least part of the blocking part 1, and the end of the suture 6 away from the blocking part 1 passes through the inner catheter 33 and is connected to the feedback part 5. Among them, by pre-placing one end of the fixed sheath 31 in the blood vessel (for example, pre-placing one end of the fixed sheath 31 in the blood vessel under the guidance of a guide wire; after one end of the fixed sheath 31 is pre-placed in the blood vessel, the guide wire can be withdrawn), the inner cavity of the fixed sheath 31 can be used as a channel for the outer catheter 32 and / or the inner catheter 33 to enter the blood vessel, and then the blocking part 1 can be transported to a suitable position in the body through the inner catheter 33 without the need for a guide wire, so as to achieve the blocking of the blood vessel puncture.

[0063] In a preferred embodiment of the blood vessel puncture port sealing device with sound and color prompts of the embodiment of the present invention, an inner tube assembly part 331 is provided at the proximal end of the inner catheter 33 (for example, the inner catheter 33 can be connected to the inner tube assembly part 331 by glue), a buckle 3311 is provided on the inner tube assembly part 331, and a slot 5123 adapted to the buckle 3311 is provided on the outer wall of the spring box 51. Among them, the arrangement of the buckle 3311 on the inner tube assembly 331 and the slot 5123 on the outer wall of the spring box 51 makes it easy to assemble the spring box 51 and the inner tube assembly 331, so that the movements of the two are synchronized; furthermore, when the wire pressing column 521 moves relative to the spring box 51, the suture 6 can also move synchronously relative to the inner catheter 33, so that at least part of the blocking part 1 (for example, the blocking sheet 12) and the locking part 2 slidably assembled in the inner catheter 33 can pass through the inner catheter 33, which is convenient for the subsequent use of the locking part 2 to lock the blocking part 1, so as to achieve the blocking of the blood vessel puncture port by the blocking part 1. Preferably, the outer tube assembly 321 has a cavity for accommodating the inner tube assembly 331, so that the outer catheter 32 and the inner catheter 33 can be coaxially arranged.

[0064] In a preferred embodiment of the blood vessel puncture port sealing device with sound and color prompts of the embodiment of the present invention, a sliding platform 45 is installed at the outer tube assembly 321, and a first thread hole and a second thread hole are provided on the sliding platform 45. The suture 6 passes through the first thread hole and the second thread hole in sequence and is connected to the feedback part 5; the line between the first thread hole and the second thread hole is perpendicular to the axial direction of the suture 6. The setting of the sliding platform 45 and the first thread hole and the second thread hole on the sliding platform 45 makes it easy to realize the turning of the suture 6.

[0065] Preferably, a boss is provided on the sliding platform 45 , and a recess is provided on the outer tube assembly part 321 , and the recess matches the boss to facilitate assembly of the sliding platform 45 and the outer tube assembly part 321 .

[0066] In a preferred embodiment of the vascular puncture port sealing device with sound and color prompts of the embodiment of the present invention, the suture 6 is arranged to pass through the anchor sheet 11, and one end of the anchor sheet 11 is pre-clamped between the outer catheter 32 and the inner catheter 33; the vascular puncture port sealing device with sound and color prompts also includes a driving unit, which is connected to the outer tube assembly 321 and is used to drive the outer catheter 32 to move relative to the inner catheter 33 in a direction away from the vascular puncture port to release the anchor sheet 11 clamped between the outer catheter 32 and the inner catheter 33, so that the anchor sheet 11 changes from the first form to the second form.

[0067] Preferably, refer to Figure 6 and 11The driving part includes a wrench 43 and a rotating shaft 44. The rotating shaft 44 passes through a sliding platform 45 (the sliding platform 45 is provided with an opening for allowing the rotating shaft 44 to pass through, and the opening extends in a direction perpendicular to the axis of the outer catheter 32) and the handle 4 (the axis of the rotating shaft 44 is perpendicular to the axis of the outer catheter 32 and / or the inner catheter 33). The two ends of the rotating shaft 44 passing through the handle 4 are respectively connected to the wrench 43. Preferably, a sliding hole 42 is provided on the handle 4 (the rotating shaft 44 passes through the sliding hole 42), and the sliding hole 42 extends in a direction from the proximal end to the distal end (the sliding hole 42 may be formed in an arc shape), and the wrench 43 can drive the rotating shaft to slide along the sliding hole 42. The above arrangement makes it possible for the wrench 43 to be rotated, and the wrench 43 drives the rotating shaft 44 to slide along the sliding hole 42 (for example, to slide toward the proximal end). Since the rotating shaft 44 is also connected to the sliding platform 45 (the rotating shaft 44 passes through the sliding platform 45), and the sliding platform 45 is assembled with the outer tube assembly 321, the outer tube assembly 321 can be driven to drive the outer catheter 32 to move toward the proximal end; thereby, the outer catheter 32 can move toward the proximal end relative to the inner catheter 33, so that the anchor sheet 11 clamped between the outer catheter 32 and the inner catheter 33 is released from the limit (after the anchor sheet 11 completely enters the blood vessel, the wrench 43 is operated to drive the outer tube to move toward the proximal end), and the anchor sheet 11 is transformed from the first form to the second form, and at this time, the anchor sheet 11 can be sealed at the position corresponding to the vascular puncture port in the blood vessel.

[0068] After the anchor sheet 11 is sealed at the position corresponding to the vascular puncture in the blood vessel, the sealing sheet 12 is located outside the blood vessel at the corresponding vascular puncture, and the anchor sheet 11 and the sealing sheet 12 are locked, and the vascular puncture can be sealed by subtracting the excess suture 6.

[0069] Specifically, the blood vessel puncture port sealing device with sound and color prompts of the present invention comprises the following steps when used:

[0070] (1) Fig.11 As shown, after one end of the graduated sheath tube 311 of the fixed sheath 31 is pre-placed at a suitable position in the blood vessel, the outer catheter 32 is inserted into the graduated sheath tube 311, and the two are locked (for example, the outer catheter 32 and the fixed sheath 31 may be provided with matching detachable connection structures respectively; the detachable connection structure may adopt corresponding components in the prior art, which will not be described in detail herein);

[0071] (2) Fig.12As shown, the wrench 43 is rotated, and the wrench 43 drives the rotating shaft 44 to slide along the sliding hole 42 (for example, slide toward the proximal end). Since the rotating shaft 44 is also connected to the sliding platform 45, and the sliding platform 45 is assembled with the outer tube assembly 321, the outer tube assembly 321 can be driven to drive the outer catheter 32 to move toward the proximal end; thereby, the outer catheter 32 can move toward the proximal end relative to the inner catheter 33, so that the anchor sheet 11 clamped between the outer catheter 32 and the inner catheter 33 is released from the limit (after the anchor sheet 11 completely enters the blood vessel, the wrench 43 is operated again to drive the outer tube to move toward the proximal end), and the anchor sheet 11 is transformed from the first form to the second form. At this time, the anchor sheet 11 can be blocked at the position corresponding to the blood vessel puncture port in the blood vessel (the axis of the anchor sheet 11 in the long axis direction is parallel or approximately parallel to the axis of the blood vessel, so that the anchor sheet 11 cannot pass through the blood vessel puncture port).

[0072] (3) Fig.13 As shown, the blood vessel puncture port sealing device with sound and color prompts of the present invention is withdrawn as a whole, the anchor sheet 11 is kept still after being close to the blood vessel puncture port, and the sealing sheet 12, the first locking piece 22, the driving tube 23 and the second locking piece 24 are sequentially passed through the inner catheter 33 (the inner catheter 33 moves toward the proximal end relative to the anchor sheet 11, so that the sealing sheet 12, the first locking piece 22, the driving tube 23 and the second locking piece 24 assembled inside the inner catheter 33 can be exposed from the inner catheter 33);

[0073] When the blood vessel puncture port sealing device with sound and color prompt of the present invention is withdrawn as a whole, pay attention to the color change and clicking sound at the observation window 41 of the handle 4 (the first indicator color and the second indicator color on the color patch 5322 are set to yellow and green respectively, and the green is located at the far end). When the observation window 41 displays green, stop withdrawing and keep the state static (color change principle: the anchor sheet 11 is static, the blood vessel puncture port sealing device with sound and color prompt of the present invention is withdrawn as a whole, the suture 6 is stressed, and the pressure buckle 52 of the feedback part 5 is pressed. The suture hole 5211 is connected with the suture 6, so that the pressure buckle 52 is forced to move relative to the spring box 51 (the pressure buckle 52 also acts on the spring coil to compress the spring coil), and the color patch 5322 moves synchronously, so that the color change can be observed at the observation window 41 of the handle 4; the "click" sound is due to the movement of the pressure column 521 relative to the spring box 51. When the protrusion 5321 on the marking pressing sheet 53 moves to the corresponding position of the spring sheet 5121, the protrusion 5321 flattens the spring sheet 5121 to deform the spring sheet and make a sound);

[0074] (4) Figure 14-15As shown, the blood vessel puncture port sealing device with sound and color prompt of the present invention is configured to lock the blocking piece 12 and the anchor piece 11 when the feedback portion 5 makes a "click" sound and / or the color at the observation window 41 changes; then after step (3), the left hand pushes the driving tube 23 toward the distal end, so that the first locking member 22 compresses the locking knot 21 and the fastening plate 12 until it cannot be pushed (preferably, at this time, one end of the driving tube 23 is located inside the skin and the other end is located outside the skin), at which time the suture 6 at the fastening plate 12 shrinks, and the fastening plate 12 shrinks, folds and is locked at the position outside the blood vessel corresponding to the blood vessel puncture port; the driving tube 23 is moved toward the proximal end so that the driving tube 23 is moved as a whole outside the skin, the excess suture 6 on the skin surface is cut off, the blood vessel puncture port is also blocked, and the blood vessel puncture port sealing device with sound and color prompt of the present invention is withdrawn. Among them, the inner diameter of the first locking member 22 and the outer diameter of the suture 6 are interference fit, and the friction force between the two is about 0.15N-0.3N, which keeps the two still in a normal state, and the driving tube 23 can also be pushed.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
