[0052] In the field of interventional medical instruments, the position close to the operator is defined as the proximal end or proximal side, and the position away from the operator is defined as the distal end or distal side. The direction of the rotation center axis of a column, a tube and the like is defined as the axial direction. The radial direction is perpendicular to the axial direction and along the diameter or radius. The circumferential direction is the direction around the axis of the column, tube and the like (perpendicular to the axis and perpendicular to the cross-sectional radius).

[0053] Referring to Figure 1 An occlusion hemostatic device is provided in an embodiment of the present application, which has opposite distal and proximal ends, and includes a positioning assembly, an occlusion assembly and a locking member 400.

[0054] The positioning assembly includes an inner tube 100, a deformation member 110 connected to the distal end of the inner tube 100, and a traction wire 120 extending through the inner tube 100 and driving the deformation member 110. The traction wire 120 is connected to the distal end of the deformation member 110. The deformation member 110 can be a deformable metal mesh cage, for example, as shown in the figure. The metal mesh cage has two axial ends, wherein the proximal end of the metal mesh cage is fixed to the inner tube 100, and the traction wire 120 is connected to the distal end of the metal mesh cage. The metal mesh cage has a contracted state before deformation and an expanded state after deformation.

[0055] The occlusion assembly includes an occlusion member 210 on the outer periphery of the inner tube 100 and an outer tube 300 wrapping the occlusion member 210, wherein the inner part of the outer tube 300 is provided with a limiting structure 310. The occlusion member 210 can be made of bioabsorbable material, such as collagen (i.e. water-absorbing and expanding material), so that the occlusion member 210 achieves excellent hemostatic effect after occluding the perforation, and the bioabsorbable material can be degraded in the human body tissue, which has high safety.

[0056] The distal end of the locking member 400 cooperates with the limiting structure 310 to limit the proximal movement of the outer tube 300. Specifically, the limiting structure 310 is an annular step provided on the inner wall of the outer tube 300, and the locking member 400 has a locked state and an unlocked state. In the locked state, the locking portion 420 abuts against the annular step to limit the proximal movement of the outer tube 300. In the unlocked state, the locking member 400 releases the abutment against the annular step to allow the proximal movement of the outer tube 300.

[0057] The occlusion and hemostasis device can further include a pushing member 220 for pushing the occlusion member 210 distally, the pushing member 220 being slidingly arranged in the radial gap 230 between the inner tube 100 and the outer tube 300 and being proximal to the occlusion member 210, and the proximal movement of the outer tube 300 exposes the pushing member 220, and the pushing member 220 can be, for example, a hollow tube sleeved on the outer surface of the inner tube 100 and slidingly fitted with the inner tube 100.

[0058] Referring to Figure 2 In the prior art, the locking member 400 usually adopts a metal claw 411, the proximal end of the metal claw 411 being fixed to the outer surface of the inner tube 100, and the distal end being naturally expanded outward under the action of elastic force to abut against the limiting structure 310. The occlusion and hemostasis device includes a moving tube 412 slidingly sleeved on the inner tube 100, the moving tube 412 serving as an unlocking member for unlocking the metal claw 411, and after the moving tube 412 slides distally, the proximal end of the metal claw 411 is folded and the distal end of the metal claw 411 is radially contracted, thereby releasing the locking of the locking member 400 to allow the proximal movement of the outer tube 300 relative to the inner tube 100.

[0059] The use process of the occlusion and hemostasis device is as follows: (1) providing an instrument channel for interventional blood vessel puncture, and partially inserting the occlusion and hemostasis device into the blood vessel along the instrument channel, so that the deformation member 110 reaches the blood vessel; (2) driving the deformation member 110 to expand, and withdrawing the occlusion and hemostasis device, so that the expanded deformation member 110 is close to the blood vessel puncture hole and abuts against the inner wall of the blood vessel; (3) unlocking the locking member 400 to allow the proximal movement of the outer tube 300 relative to the inner tube 100; (4) withdrawing the outer tube 300, and keeping the inner tube 100 in place, so that the distal end of the pushing member 220 is exposed, and the occlusion member 210 is pushed by the pushing member 220, and the occlusion member 210 is pushed and kept in place to absorb liquid and expand to stop bleeding; (5) the deformation member 110 returns to the original state, and the inner tube 100 is withdrawn, and the operation is completed. The operation procedures of the above (1)-(5) are relatively complicated, and it is easy to cause the outer tube 300 to be pierced by the locking member 400 due to the failure to unlock the locking member 400, and further cause the operation to fail.

[0060] Referring to Figure 3In an embodiment of the present application, the proximal end of the locking member 400 moves synchronously with the traction wire 120. When the deformation member 110 is expanded by driving the traction wire 120, the unlocking of the locking member 400 is automatically synchronized, which simplifies the operation process of the occlusion and hemostasis device and avoids adverse consequences caused by operation errors. This embodiment is particularly advantageous when multiple puncture ports are simultaneously used in electrophysiology ablation surgery and other procedures to stop bleeding using the occlusion and hemostasis device.

[0061] The locking member 400 includes a locking portion 420 abutting against the limiting structure 310, and a driving wire 430 connected to the locking portion 420 and extending through the inner tube 100. The proximal end of the driving wire 430 is fixedly connected to the traction wire 120, achieving synchronous movement of the proximal end of the locking member 400 with the traction wire 120, for example, by fixing the proximal ends of the driving wire 430 and the traction wire 120 with a metal ring. When the driving wire 430 moves proximally with the traction wire 120, the locking portion 420 disengages from the annular step, and the locking member 400 enters the unlocked state to allow the outer tube 300 to move proximally relative to the inner tube 100. In some embodiments, the locking portion 420 is multiple and arranged in sequence in the circumferential direction, and each locking portion 420 shares the same driving wire 430 or is respectively provided with a driving wire 430.

[0062] The locking portion 420 and the driving wire 430 are an integral structure, and the driving wire 430 is composed of one or more metal round wires or flat wires. The end of the locking member 400 has a smooth outer surface, for example, the end of the locking portion 420 is a ball cap portion 421 with an enlarged diameter, and the ball cap portion 421 is entirely circular or hemispherical. During the intervention operation, the ball cap portion 421 can avoid the situation that the occlusion member 210 cannot be released after the locking member 400 pierces the outer tube 300 due to accidental pressing of the outer tube 300. Further, the outer wall of the inner tube 100 is fixedly sleeved with a reinforcing tube 101, and the corresponding parts of the inner tube 100 and the reinforcing tube 101 are provided with through holes 102 for the locking member 400 to pass through, and the reinforcing tube 101 can be made of metal.

[0063] In some embodiments, the locking member 400 has a limit position when switching to the unlocked state, and the limit position is determined by (a) and / or (b). (a) method: the size of the through hole 102 is smaller than the ball cap portion 421 to limit the locking portion 420 from entering the inner tube 100. (b) method: the traction wire 120 has a first stroke for moving proximally and driving the deformation member 110 to radially expand, and at the first stroke, at least a part of the locking member 400 is outside the inner tube 100 or located in the through hole 102.

[0064] Referring to Figure 4The occlusion and hemostasis device comprises an unlocking tube 500 movably sleeved on the outer periphery of the inner tube 100 at the proximal end of the inner tube 100, and the proximal end of the traction wire 120 and the driving wire 430 are both followed by the unlocking tube 500. The unlocking tube 500 and the inner tube 100 are provided with mutually matched axial limiting structures.

[0065] The axial limiting structure comprises, for example, a clamping protrusion provided on the inner wall of the inner tube 100, and the unlocking tube 500 is internally fixed with a connecting part 510 inserted into the inner tube 100, the traction wire 120 is connected with the connecting part 510, and a protrusion 511 is arranged on the outer wall of the connecting part 510. In the contracted state of the shape-changing member 110, the protrusion 511 of the unlocking tube 500 is located on the distal end side of the clamping protrusion of the inner tube 100.

[0066] In use, the inner tube 100 is held, the unlocking tube 500 is moved relative to the inner tube 100 towards the proximal end, the connecting part 510 drives the traction wire 120 to move towards the proximal end, the driving wire 430 fixed to the traction wire 120 is moved synchronously, the shape-changing member 110 is expanded and the locking member 400 is unlocked. In this process, the protrusion 511 of the unlocking tube 500 is moved relative to the clamping protrusion of the inner tube 100 towards the proximal end and beyond the clamping protrusion of the inner tube 100. After the unlocking tube 500 is released, the protrusion 511 of the unlocking tube 500 is blocked by the clamping protrusion of the inner tube 100. In this way, a larger force is required to make the protrusion 511 of the unlocking tube 500 beyond the clamping protrusion of the inner tube 100, so that the shape-changing member 110 remains in the expanded state and the locking member 400 remains in the unlocked state.

[0067] Referring to Figures 5-7 In some embodiments, the axial limiting structure comprises a protrusion and a protrusion. Among them, the protrusion is arranged on one of the inner tube and the unlocking tube, the protrusions are arranged in pairs and a sliding groove is formed between the protrusions. The protrusion is arranged on the other one of the inner tube and the unlocking tube, the protrusion is axially slidably matched with the sliding groove, the unlocking tube 500 is moved relative to the inner tube 100 towards the proximal end to make the protrusion disengage from the sliding groove, and the protrusion is blocked by the end of the protrusion after the unlocking tube rotates relative to the inner tube.

[0068] Specifically, the proximal end of the inner tube 100 has an extended section 105 extending out of the outer tube 300 and radially outwardly expanding, the extended section 105 is an integral structure with other parts of the inner tube 100 or is fixed in a separate body, and the extended section 105 can adopt a metal tube. The tube wall of the extended section 105 is partially deformed inwardly to form a protrusion 107. The unlocking tube 500 is internally fixed with a connecting part 510 inserted into the inner tube 100, the traction wire 120 is connected with the connecting part 510, and a protrusion 511 is arranged on the outer wall of the connecting part 510.

[0069] In the embodiment, the deformation member 110 is in the contracted state, the protrusion 511 of the unlocking tube 500 is at the distal end side of the sliding groove 106 of the extension section 105 of the inner tube 100, and the protrusion 511 reaches the first position S1 in the figure. In use, the extension section 105 is held, the unlocking tube 500 is moved proximally relative to the inner tube 100, the connecting section 510 drives the traction wire 120 to move proximally, the driving wire 430 fixed to the traction wire 120 is moved synchronously, the deformation member 110 is expanded and the locking member 400 is unlocked. At the same time, the protrusion 511 of the unlocking tube 500 freely passes through and exceeds the sliding groove 106 of the extension section 105, and the protrusion 511 reaches the second position S2 in the figure. After the unlocking tube 500 is rotated relative to the inner tube 100, the protrusion 511 of the unlocking tube 500 abuts against the protruding rib 107 of the extension section 105, the protrusion 511 reaches the third position S3 in the figure, and the expanded state and the unlocked state are maintained. After the hemostatic plugging is completed, the extension section 105 of the inner tube 100 is held, the unlocking tube 500 is rotated, the protrusion 511 of the unlocking tube 500 enters the sliding groove 106, the deformation member 110 is restored to be pulled by the traction wire 120 to move distally, and the deformation member 110 enters the contracted state, so as to facilitate the recovery.

The technical features of the above-described embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope disclosed in the present specification.

[0071] The above-described embodiments only express several implementation manners of the present application, the description is more specific and detailed, but it cannot be understood as the limitation of the patent application scope. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are within the protection scope of the present application.
