Abstract
Description
Technical Field
[0001] This application relates to the field of hemostatic device technology, and more specifically, to an adjustable pressure non-invasive hemostatic clip device. Background Technology
[0002] During clinical surgical procedures, surgeons often need to temporarily occlude blood vessels, a process typically involving the use of hemostatic clips. Currently, most clinically used hemostatic clips consist of two clamps and a spring. However, this traditional hemostatic clip has significant drawbacks. Firstly, due to variations in vascular conditions among patients, the inability to adjust the clamping force makes it difficult to adapt flexibly to the specific situation, resulting in inconsistent clamping effectiveness. Secondly, the lack of adjustable clamping force means that excessive clamping force can easily damage blood vessels, potentially leading to vasospasm or even thrombosis.
[0003] There is currently no effective solution to the problem that the clamping force of the hemostatic clips is not easily adjustable, which can easily damage the patient's blood vessels. Summary of the Invention
[0004] The main objective of this application is to provide an adjustable pressure non-invasive hemostatic clip device to solve the problem that the clamping force of the hemostatic clip is not easy to adjust flexibly, which can easily damage the patient's blood vessels.
[0005] To achieve the above objectives, this application provides an adjustable pressure non-invasive hemostatic clip device.
[0006] The adjustable pressure non-invasive hemostatic clip device according to this application includes:
[0007] shell;
[0008] The first clamping plate is slidably installed inside the outer casing;
[0009] The second clamping plate is slidably installed inside the outer shell and is symmetrically arranged with the first clamping plate;

[0017] Limiting rods are symmetrically arranged on both sides of the threaded rod, and the limiting rods are parallel to the threaded rod.
[0018] The two ends of the limiting rod are respectively connected to the inner wall of the outer shell and the limiting plate.
[0019] Furthermore, the first clamping plate is the same as the second clamping plate;
[0020] The first clamping plate comprises: a clamping part, a connecting part connected to the clamping part, and an abutting part connected to the other end of the connecting part; the abutting part is inclined toward one end of the push block.
[0021] Furthermore, the push block comprises: two symmetrically arranged pushing parts and a transition part connecting the two pushing parts; the pushing parts and the transition part are integrally formed;

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0044] like Figure 1-6 As shown, this application relates to an adjustable pressure non-invasive hemostatic clip device, which includes: a housing 1 for carrying components disposed therein.
[0045] The first clamp 2 is slidably installed in the outer shell 1 along the longitudinal direction; the second clamp 3 is slidably installed in the outer shell 1 along the longitudinal direction and is symmetrically arranged with the first clamp 2; the first clamp 2 and the second clamp 3 are used to cooperate with each other to achieve an open and closed state, so as to clamp the blood vessel.
[0046] The return spring 4 brings the first clamping plate 2 and the second clamping plate 3 closer together.
[0047] As an alternative, the two ends of the return spring 4 are connected to the first clamping plate 2 and the first clamping plate 2 respectively, so that the first clamping plate 2 and the first clamping plate 2 can be brought closer to each other.
[0048] As an alternative, there are two return springs 4, one of which has its two ends connected to the first clamping plate 2 and the inner wall of the outer shell 1 respectively; the other of which has its two ends connected to the second clamping plate 3 and the inner wall of the outer shell 1 respectively.
[0049] Push block 5 is slidably installed in the outer casing 1, and the two ends of the push block 5 on the push-out side abut against the first clamping plate 2 and the second clamping plate 3 respectively, so as to push the first clamping plate 2 and the second clamping plate 3 away from each other by push block 5.
[0050] As a supplement, the first clamp 2 and the second clamp 3 can be manually pushed apart to move them away from each other, thereby opening the hemostatic clamp. By pushing the pusher 5 towards the first clamp 2 and the second clamp 3, the distance between them can be finely adjusted to increase the shortest distance between them, thus playing an adjustment role.
[0051] From the above description, it can be seen that this application achieves the following technical effects: In this embodiment, a sliding pusher 5 is used to move the first clamp 2 and the second clamp 3 away from each other through the outer shell 1; the first clamp 2 is slidably installed inside the outer shell 1; the second clamp 3 is slidably installed inside the outer shell 1 and is symmetrically arranged with the first clamp 2; a return spring 4 moves the first clamp 2 and the second clamp 3 closer to each other; the pusher 5 is slidably installed inside the outer shell 1, and the two ends of the pusher 5 protruding side abut against the first clamp 2 and the second clamp 3 respectively, thereby achieving the purpose of adjusting the distance between the first clamp 2 and the second clamp 3, thus achieving the technical effect of adjusting the clamping force, and thus solving the technical problem that the clamping force of the hemostatic clip is difficult to adjust, which can easily damage the patient's blood vessels.
[0052] Preferably, the push block 5 is threadedly connected to a threaded rod 6; one end of the threaded rod 6 protrudes from the outer casing 1, and the end of the threaded rod 6 protruding from the outer casing 1 is connected to a toggle block 7. By rotating the toggle block 7, the threaded rod 6 is driven to rotate, thereby driving the push block 5 to slide laterally inside the outer casing 1. This allows the operator to precisely control the lateral sliding position of the push block 5 inside the outer casing 1 by rotating the toggle block 7 to drive the threaded rod 6, thus meeting the usage requirements under different conditions.
[0053] The other end of the threaded rod 6 is rotatably connected to the limiting plate 8, which is used to cooperate with the outer shell 1 to stabilize the threaded rod 6 and the limiting rod 9. The limiting rods 9 are symmetrically arranged on both sides of the threaded rod 6, and the limiting rods 9 are parallel to the threaded rod 6 and are cylindrical. The two ends of the limiting rods 9 are respectively connected to the inner wall of the outer shell 1 and the limiting plate 8, which are used to limit the movement path of the push block 5, improve the stability of the push block 5 during the sliding process, and ensure the reliability and accuracy of the device during use.
[0054] Preferably, the first clamping plate 2 is the same as the second clamping plate 3; the first clamping plate 2 includes: a clamping part 10, a connecting part 11 connected to the clamping part 10, and an abutting part 12 connected to the other end of the connecting part 11; the abutting part 12 is inclined toward the end of the push block 5.
[0055] The push block 5 includes two symmetrically arranged pushing parts 13 and a transition part 14 connecting the two pushing parts 13; the abutting part 12 and the pushing part 13 of the push block 5 cooperate well, so that the push block 5 can more smoothly drive the first clamping plate 2 and the second clamping plate 3 to separate or move closer during the sliding process.
[0056] The propulsion part 13 and the transition part 14 are integrally formed, with a stable structure and easy processing.
[0057] The two pushing parts 13 respectively abut against the abutting parts 12 of the first clamping plate 2 and the second clamping plate 3, so that when the pushing block 5 slides close to the first clamping plate 2 or the second clamping plate 3, it can drive the first clamping plate 2 and the second clamping plate 3 to separate from each other, and when the pushing block 5 slides away from the first clamping plate 2 or the second clamping plate 3, the first clamping plate 2 and the second clamping plate 3 will move closer to each other through the action of the spring.
[0058] Preferably, it further includes: a first push rod 15, which passes through the outer shell 1 and the second clamping plate 3 in sequence and is connected to the first clamping plate 2; a second push rod 16, which passes through the outer shell 1 and the first clamping plate 2 in sequence and is connected to the second clamping plate 3; by pressing the first push rod 15 and the second push rod 16, the first clamping plate 2 and the second clamping plate 3 can be moved away from each other.
[0059] Preferably, push caps 17 are installed on the first push rod 15 and the second push rod 16 respectively, making it easy to press the push rods. During the operation, when a hemostatic clip is needed, the doctor holds a hemostatic forceps or surgical forceps and uses its two movable ends to clamp the two push caps 17 respectively, so that the first push rod 15 and the second push rod 16 are separated. After obtaining the clamping position, the hemostatic forceps or surgical forceps are released, and the first push rod 15 and the second push rod 16 automatically move closer together. If it is necessary to adjust the clamping force, the toggle block 7 can be rotated before the clamping action to loosen or tighten it, or it can be adjusted after the clamping action. The doctor can use the hemostatic forceps or surgical forceps to conveniently clamp the push caps 17, so that the first clamp 2 and the second clamp 3 are far apart, thus easily obtaining the hemostatic clip without complicated additional operations, and can quickly obtain the required hemostatic clip during the operation, saving time.
[0060] Preferably, the outer shell 1 is composed of a shell and a cover that is detachably connected to the shell; a movable groove 18 is provided on one side of the shell, and the clamping part 10 extends out of the movable groove 18 to avoid interference with the clamping part 10; a sliding groove 19 is provided inside the shell to facilitate sliding connection with the first clamping plate 2 and the second clamping plate 3.
[0061] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
