Description
Technical Field

Background
In recent years, vascular interventional therapy has been rapidly developed due to advantages such as minimally invasive, rapid, safe and effective, and is one of relatively mature and representative technologies in interventional therapy. Transarterial puncture is one of the common approaches to interventional diagnosis and treatment, and the vascular complications of the puncture during the same operation are always problems that each interventional physician has to face frequently.
The hemostasis method for the puncture hole after the arterial intervention operation comprises the following steps: manual compression hemostasis, mechanical compression hemostasis, vascular occlusive hemostasis, and the like. Artificial compression hemostasis is the most traditional method of arterial hemostasis. The advantage is that it is economical, relatively reliable, and ultimately still needs to be addressed and remedied by other methods when hemostasis fails. However, the defects are also obvious, and the long-time compression hemostasis and lying in bed by the manual compression method not only increase the labor capacity of medical staff, but also increase the pain of patients. If the patient is obese or the puncture part is too high or too low, the complications such as difficult compression, local hematoma, pseudo-aneurysm, arteriovenous fistula, vagal reflex, lower limb venous thrombosis and the like can be caused. The mechanical compression hemostasis method mainly compresses the artery puncture part from outside the body through mechanical compression force, and promotes the hemostasis healing of the puncture. Mechanical compression hemostasis reduces the workload of medical staff, but other drawbacks of manual compression hemostasis remain unsolved.
The puncture hole closing device for clinical application solves the defects of a manual compression hemostasis method and a mechanical compression hemostasis method, has the advantages of quick response and wide application range, but also has the defects of poor hemostasis effect, low success rate, higher cost, higher intervention technical foundation for operators, more complex operation, difficult mastering of beginners in a short time and the like.

Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
In order to more clearly describe the structure of the puncture closure device, the terms "distal" and "proximal" are defined herein as conventional terms in the field of interventional medical devices. Specifically, "distal" refers to the end of the procedure that is distal to the operator, and "proximal" refers to the end of the procedure that is proximal to the operator.
As shown in fig. 1 to 3, the puncture closure device 1 of the present invention includes: an outer tube 11 having a lumen extending axially therethrough; a push tube 12 movably disposed within the lumen of the outer tube 11; a sealant 13 movably disposed within the lumen of the outer tube 11 and abutting the distal end of the push tube 12; a handle 14 connected to the proximal ends of the outer tube 11 and the push tube 12. Wherein the sealant 13 is made of a material which can absorb and expand in volume when contacting with human tissue fluid, such as PGA, PLGA, PEG, PCL, PDO, collagen, silk fibroin, sodium alginate, calcium alginate, gelatin, and chitosan. The sealant 13 is in a solid state when not contacted with the human tissue fluid, and the sealant 13 gradually changes into a semi-fluid colloid state after reacting with the human tissue fluid. The puncture closure device 1 further includes a guide wire 15 and a positioning member 16 provided on a distal end side of the guide wire 15, the guide wire 16 passing through the push tube 12 and the sealant 13 such that the positioning member 16 is located on a distal end of the sealant 13. The positioning member 16 has an expandable structure, and the positioning member 16 expands after entering the blood vessel from the puncture hole, and when the guide wire 15 is pulled, the positioning member 16 abuts against the inner side of the blood vessel wall and temporarily blocks the puncture hole.
As shown in fig. 4, the handle 14 includes a housing 141 and a release driver 142, an outer tube driver 143, a push tube driver 144, and a guidewire driver 145 disposed within the housing 141; the outer tube transmission piece 143 is connected with the outer tube 11 to drive the outer tube 11 to axially move relative to the outer shell 141; the push tube transmission piece 144 is connected with the push tube 12 to drive the push tube 12 to axially move relative to the housing 141; the guide wire transmission member 145 is coupled to the guide wire 15 to drive the guide wire 15 to move axially relative to the housing 141.
When the puncture closure device is in the first state, as shown in fig. 4, the release driver 142 is coupled to the housing 141, the outer tube driver 143 is coupled to the release driver 142, and as shown in fig. 5, the push tube driver 144 abuts the guide wire driver 145. Thus, when the housing 141 is pulled in a proximal direction and the positioning member 16 is subjected to a resistance force in a proximal-to-distal direction without moving with the housing, the guidewire driver 145 pushes the push tube driver 143 to move the push tube driver 143 distally with the positioning member 16 relative to the outer tube 11 and the housing 141 to at least partially expose the sealant 13 to the outer tube.
Because the positioning member 16 is subjected to resistance in the direction from the proximal end to the distal end, the push tube 12 moves along with the positioning member 16, that is, the sealant 13 moves along with the positioning member 16, so that the vessel wall is always clamped between the positioning member 16 and the sealant 13, and the puncture closure device 1 can be integrally moved distally by avoiding forming a gap between the positioning member 16 and the sealant 13, thereby avoiding temporary blocking failure and avoiding the sealant from entering the vessel. In addition, the relative withdrawal of the outer tube 11 during the formation of the temporary closure enables the partial sealant 13 to be exposed and the outer layer of the partial sealant 13 to be brought into a semi-fluid state in advance, so that the partial sealant 13 can better penetrate into the gaps of the tissues and the puncture holes can be closed more quickly.
The puncture closure device 1 is capable of being changed from a first state to a second state when the positioning member 16 receives resistance in a proximal-to-distal direction. As shown in fig. 6, when the puncture closure device 1 is in the second state, the push tube transmission member 144 is coupled to the release driving member 142, the push tube transmission member 144 is capable of moving distally under the driving of the release driving member 142, and at the same time, the outer tube transmission member 143 is capable of moving proximally under the driving of the release driving member 142. Therefore, in the second state, the medical staff can control the outer tube 11 to withdraw and the push tube 12 to advance simultaneously, so that the sealant 13 arranged in the outer tube 11 can be exposed to the human tissue environment and simultaneously pressed forward by the push tube 12, thereby better sealing the puncture hole.
Specifically, as shown in FIG. 7, the release drive 142 has a push tube drive path 1422, the push tube drive path 1422 including a first segment 14221 and a second segment 14222; the push tube transmission member 144 has a push tube connection 1441, and the push tube connection 1441 is coupled to the push tube driving path 1422. When the puncture closure device 1 is in the first state, the push tube connecting part 1441 can move along the first segment 14221 under the pushing of the guide wire driving member 145; when the puncture closure device 1 is in the second state, the push tube connecting portion 1441 can move along the second segment 14222 under the driving of the release driving member 142. The push tube driving path 1422 is provided, and the push tube driving member 144 is driven by the outer tube driving member 143 and the guide wire driving member 145, respectively.
In this embodiment, the release driving member 142 has a cavity 1423 extending axially therethrough, the second section 14222 is an internal thread provided on an inner wall of the cavity 1423, the first section 14221 is a groove connected to a start end of the second section 14222, and the first section 14221 extends along an axial direction of the release driving member 142. Thus, as the guidewire transmission member 145 moves distally relative to the housing 141, releasing the drive member 142, the push tube transmission member 144 is urged to move along the first segment 14221; the release driving member 142, when rotated by an external force, drives the push tube driving member 144 to move along the second segment 14222.
The release driving member 142 is at least partially exposed to the housing 141, so as to rotate under the action of external force and drive the outer tube 11 and the push tube 12 to move in opposite directions. Referring back to fig. 1, the housing 141 is provided with an operation window 1413, and the release actuator 142 is exposed from the operation window 1413 to the housing 141. The operating window 1411 restricts movement of the release driver 142 relative to the housing 141 in the axial direction of the handle 14 such that when the housing 141 is moved proximally under tension, the release driver 142 moves therewith.
The release drive 142 further includes an outer tube drive path 1421, the outer tube drive path 1421 is disposed distally of the push tube drive path 1422, the outer tube drive path 1421 is an internal thread disposed on the inner wall of the cavity 1423, and the outer tube drive path 1421 is opposite to the thread of the second segment 14222. The outer tube driving member 143 and the push tube driving member 144 are disposed in the cavity 1423. The release actuator 142 serves as both an actuating member for the outer tube 11 and push tube 12 and also provides space for accommodating the outer tube transmission 143, push tube transmission 144, outer tube 11 and push tube 12, reducing the required length of the handle 14.
The puncture closure device 1 of the present invention controls the outer tube 11 to be withdrawn and the push tube 12 to be advanced by providing the release driving part 142, so that the sealant 13 provided in the outer tube 11 can be pressed forward by the push tube 12 while being exposed to the environment of human tissue, thereby sealing the puncture well. Meanwhile, the release driving member 142 drives the push tube 12 and the outer tube 11 to move step by step under the action of external force, so that the sealant 13 can be released stably and react with human tissues better, and the sealing effect is improved. In this embodiment, when the puncture closure device 1 is in the second state, the release driving member 142 is in threaded engagement with the outer tube driving member 143 and the push tube driving member 144, the outer tube 11 and the push tube 12 can only move axially when the release driving member 142 rotates, and the release driving member 142 cannot be driven to rotate by the axial movement of the outer tube 11 and the push tube 12, i.e. the release driving member 142 has a good self-locking function, so that the inner movement mechanism of the entire handle 4 can be prevented from being driven to move when the outer tube 11 is pulled in an additional axial direction.
In other embodiments, the first segment of the push tube driving path may be a linear slot parallel to the axial direction of the release driving member, and the second segment may be a linear slot inclined with respect to the axial direction of the release driving member, where the release driving member is capable of driving the push tube driving member to move along the axial direction of the puncture closure device when being pressed by an external force; or the first segment is also a linear slot inclined with respect to the axial direction of the release driver; or other structure capable of enabling the push tube transmission member to be pushed by the guide wire transmission member in a first state and to be driven by the release driving member in a second state.
In this embodiment, the thread lead of the outer tube drive path 1421 is greater than the thread lead of the second segment 14222, where thread lead refers to the axial distance that any point on a thread moves one revolution along the same helical line. That is, when the release driver 142 is rotated by external force, the outer tube driver 143 and the outer tube 11 have a greater moving speed than the push tube driver 144 and the push tube 12, so that when the push speed of the push tube 12 is the same, the outer tube 11 having a greater moving speed can expose more sealant 13, and the sealant 13 of the outer layer becomes a half-flowing state in advance, so that it is better penetrated into the gaps of the tissue. It should be noted that if the outer tube 11 is withdrawn in sequence and the push tube 12 is pushed forward, the push tube 12 may not be able to transmit the pushing force to the sealing agent 13 due to the sealing agent 13 becoming a half-flowing state, so by controlling the speed of the outer tube 11 and the push tube 12 moving simultaneously, the pushing force of the push tube 12 can be transmitted to the sealing agent 13, and the sealing agent 13 can better permeate into the gap of the tissue.
