Description

hemostatic clip Technical Field

[0001] This disclosure relates to the field of hemostatic clip technology, specifically to a hemostatic clip. Background Technology

[0002] With the development of endoscopic technology and other related technologies, endoscopic hemostasis has become the preferred treatment method for gastrointestinal bleeding. Commonly used endoscopic hemostasis methods include laser coagulation, electrocoagulation, local injection of hemostatic agents, drug spraying, and suture clipping. Among these, suture clipping has become the most effective and clinically valuable non-surgical treatment for gastrointestinal bleeding due to its minimal invasiveness, rapid hemostasis, low rebleeding rate, few complications, and definite efficacy.

[0003] Based on the operational characteristics of the hemostatic clip closure method, the clip head needs to remain inside the body to maintain closure of the wound. Therefore, it is necessary to detach the clip head from the rest of the clip, i.e., the clip release operation. However, current hemostatic clips sometimes fail to release the clip head completely, or even fail to release at all, leading to the failure of the closure hemostasis operation.

[0048] Example 1

[0049] Referring to Figures 1 to 10, this embodiment proposes a hemostatic clip, including a base 1, a transmission rod 2, two secondary connecting rods 9, and two clamping pieces 3; the two clamping pieces 3 intersect and are hinged to the base 1, and a deformation fracture piece 31 is fixedly provided at the tail of the clamping piece 3; one end of the secondary connecting rod 9 is provided with a limiting hole 91, which is rotatably engaged with the deformation fracture piece 31; a breaking part 90 is provided on the inner wall of the limiting hole 91, which is used to cut the deformation fracture piece 31; the other end of the secondary connecting rod 9 is movably connected to the transmission rod 2; one of the connected secondary connecting rod 9 and the transmission rod 2 is provided with a connecting piece 21, and the other is provided with a connecting hole 92, which is rotatably engaged with the connecting hole 92.

[0050] In this embodiment, the hemostatic clip can control the opening and closing of the clip 3 by pushing and pulling the transmission rod 2. Furthermore, when the clip 3 is closed, the connection between the clip 3 and the secondary connecting rod 9 can be fully disconnected. The axial movement of the transmission rod 2 is achieved through the cooperation of the transmission rod 2 with the rest of the hemostatic clip, which can be referred to in the general design of existing hemostatic clips and will not be described in detail here.

[0051] In this embodiment, the working process includes: opening and closing of the clamp 3, and disengagement of the clamp 3 from the secondary connecting rod 9 after it is closed.

[0052] The working principle of opening and closing of the clamping plate 3 is as follows: During the axial movement of the transmission rod 2, it will drive the secondary connecting rod 9 to move. The secondary connecting rod 9 will exhibit a combination of swinging and translational motion. The two clamping plates 3 intersect and are hinged to the base 1. When the secondary connecting rod 9 moves, it can drive the two clamping plates 3 to swing, thereby realizing opening and closing.

[0053] The disengagement of the clamp 3 from the secondary connecting rod 9 after closure works as follows: When the clamp 3 is fully closed, the transmission rod 2 continues to be pulled away from the base 1. Because the clamp 3 has a tendency to continue closing, the clamped lesion tissue transmits a force opposite to the movement tendency to the two clamps 3, or between the two clamps 3. As the transmission rod 2 continues to move, it drives the secondary connecting rod 9 to continuously apply pressure to the deformed fracture member 31, thereby allowing the breaking part 90 to break the deformed fracture member 31. In this embodiment, "breaking" refers to causing deformation or fracture of the deformed fracture member 31.

[0054] The breaking part 90 can be a portion of the inner wall of the limiting hole 91 with a relatively small thickness, or a cutting edge or blade formed on the inner wall of the limiting hole 91, etc., capable of cutting. In this case, the breaking part 90 will gradually cut into the deformable fracture member 31 until the deformable fracture member 31 is completely cut open. Once the deformable fracture member 31 is completely cut open, the secondary connecting rod 9 and the clamping piece 3 can be fully disengaged. It should be noted that this implementation requires that the hardness of the deformable fracture member 31 be relatively low, while the hardness of the breaking part 90 be relatively high, in order to achieve the cutting effect. For example, the breaking part 90 (i.e., the secondary connecting rod 9) can be made of metal, and the deformable fracture member 31 can be made of plastic.

[0055] The breaking part 90 can also be a portion of the inner wall with a certain thickness and strength. Since the breaking part 90 is the part of the inner wall of the limiting hole 91 that abuts against the deformed fracture member 31, it can continuously apply pressure to the deformed fracture member 31 to cause it to deform. When the deformation of the deformed fracture member 31 reaches its limit, it will cause the limiting hole 91 to disengage from the deformed fracture member 31. At this time, the secondary connecting rod 9 can also be fully disengaged from the clamping piece 3.

[0056] When the damaging part 90 is a portion of the inner wall of the limiting hole 91 with a small thickness, or a cutting edge or blade formed on the inner wall of the limiting hole 91, which can achieve cutting, the damaging part 90 may damage the deformable fracture member 31 when the clamping plate 3 is opened and closed, since it is located on the inner wall of the limiting hole 91. Therefore, it is necessary to control the distribution of the damaging part 90 to avoid excessive damage to the deformable fracture member 31 and affecting the connection between the clamping plate 3 and the secondary connecting rod 9. Therefore, in one embodiment, the damaging part 90 is located on the inner wall of the limiting hole 91 on the side away from the transmission rod 2. In this embodiment, it can be ensured that during the process of the transmission rod 2 pushing the secondary connecting rod 9 axially, that is, during the opening of the clamping plate 3, the portion of the limiting hole 91 that abuts the deformable fracture member 31 does not have the damaging part 90, so that the damaging part 90 does not cut into or minimally cuts into the deformable fracture member 31 during this process, thus avoiding damage to the deformable fracture member 31 without disconnecting the connection between the clamping plate 3 and the secondary connecting rod 9.

[0057] In the above embodiment, since the distribution range of the breaking part 90 is reduced, the cutting effect on the deformed fracture member 31 will inevitably be limited. Therefore, the distribution range of the breaking part 90 cannot be too small. Therefore, based on the above embodiment, it can be further improved to the embodiment shown in Figure 3: the breaking part 90 is arc-shaped, and the central angle α corresponding to the breaking part 90 is greater than or equal to 150°. This design ensures the lower limit of the distribution range of the breaking part 90, ensuring that the breaking part 90 can fully cut the deformed fracture member 31.

[0058] As explained above, in this embodiment, the two ends of the secondary connecting rod 9 are connected to the transmission rod 2 and the clamping plate 3, respectively, forming an intermediate structure connecting the transmission rod 2 and the clamping plate 3. To ensure the machinability of the breaking part 90, for example, by additionally machining the aforementioned cutting structure on the inner wall of the limiting hole 90, in a preferred embodiment, the diameter of the limiting hole 91 should be larger than the diameter of the connecting hole 92. Obviously, a relatively larger limiting hole 91 makes it easier to machine the breaking part 90. Correspondingly, the diameter of the deformable fracture member 31 should be larger than the diameter of the connecting member 21.

[0059] It should be noted that although the secondary connecting rod 9 and the transmission rod 2 are also connected by a shaft hole, the connecting piece 21 can be set on the secondary connecting rod 9 or the transmission rod 2, and the connecting hole 92 can be set accordingly.

[0060] According to the operation procedure of the hemostatic clip clamping method, after clamping the lesion, the clip 3 must be kept in a clamped state, which involves locking the clip 3. In a preferred embodiment, referring to Figures 5 to 7, a snap-fit ​​protrusion 33 is fixedly provided on the side of the tail of the clip 3 away from the deformed fracture member 31, and a locking platform 10 is provided on the base 1. The locking platform 10 is located on one side of the center line L of the base 1. The two locking platforms 10 corresponding to the two clips 3 are centrally symmetrically arranged on the base 1, and the locking platform 10 is used to abut against the snap-fit ​​protrusion 33.

[0061] Based on this implementation method, the principle of locking the clamp 3 after closing is as follows: as the clamp 3 closes continuously, the locking protrusions 33 at the tails of the two clamps 3 will gradually move towards the center line L. During the movement, the locking protrusions 33 at the tails of the clamp 3 will come into contact with the side of the locking platform 10 away from the center line L. If the transmission rod 2 is pulled further, the locking protrusions 33 will pass over the locking platform 10. At this time, if the clamp 3 wants to move in the opposite direction, the locking protrusions 33 will be restricted by the locking platform 10, which will prevent the clamp 3 from reopening. This means that the clamp 3 can only remain in the closed state, thereby achieving the locking of the clamp 3 in the closed state.

[0062] In the above embodiments, since the clamping piece 3 has a locking protrusion 33 at its tail, the locking protrusion 33 may interfere with the base 1 when the clamping piece 3 swings. Therefore, in a further embodiment, a first groove 14 and a second groove 13 are respectively provided on both sides of the locking platform 10. The first groove 14 is located on the side of the locking platform 10 away from the center line L, and the second groove 13 is located on the side of the locking platform 10 facing the center line L. Thus, the first groove 14 and the second groove 13 provide a space for the locking protrusion 33, avoiding interference between the locking protrusion 33 and the base 1. The widths of the first groove 14 and the second groove 13 can be equal or unequal, but generally the width of the second groove 13 can be set to be smaller than the width of the first groove 14.

[0063] According to the clamping procedure, the clamp 3 and base 1 need to be advanced along the endoscopic forceps channel to the vicinity of the lesion. Therefore, it is necessary to control the width of the clamp head 3 to facilitate its entry into the forceps channel. In a preferred embodiment, the clamp 3 includes clamping arms 35. For any clamp 3, the head of the clamping arm 35 is tilted towards the side where the clamping arm 35 of the other clamp 3 is located. When the clamp 3 is fully closed, all clamping arms 35 are tilted inward, significantly reducing the distance between the heads of adjacent clamping arms 35. This greatly reduces the width of the clamp assembly end, making it easier to insert the clamp assembly into the endoscopic forceps channel. In a preferred embodiment, the tilt angle A of the clamping arm 35 is 0° to 30°.

[0064] Because current clamping assemblies, such as the clamping plate 3, are mostly made of stainless steel or other metals, the clamping assembly itself may contain magnetism. This could prevent patients who have undergone endoscopic minimally invasive treatment from undergoing MRI examinations for a short period of time and from passing security checks when traveling. Therefore, in a preferred embodiment, the clamping plate 3 and the base 1 can be made of non-magnetic elastic materials or non-magnetic absorbable materials, respectively. Specific materials include pure titanium, magnesium alloy, zinc alloy, polylactic acid, polyglycolic acid, polyglycolic acid, polyglycolic acid-trimethylene carbonate, polyetheretherketone, polyamide, polyoxymethylene, ultra-high molecular weight polyethylene, and polycarbonate. In a preferred embodiment, pure titanium or polyetheretherketone can be selected as needed. This ensures that the clamping assembly remains in the body and is compatible with MRI examinations, meaning it does not affect the patient's MRI examination or security checks. Furthermore, it is understood that when the breaking part 90 is a structure capable of cutting, used to cut the deformed fractured part 31, the clamping plate 3 should not be made of a material with high hardness; a non-metallic material is generally preferred. Correspondingly, the secondary connecting rod 9 should be made of a metal material with high hardness.

[0065] Example 2

[0066] Referring to Figures 11 to 13, the hemostatic clip of this embodiment, compared with the technical solution of Embodiment 1, can be improved as follows: it further includes a rotating ring seat 4, a first rotating ring 5, a second rotating ring 6, and a hook 7. The rotating ring seat 4 is located on one side of the base 1, and a limiting block 40 is fixedly provided on the rotating ring seat 4. The first rotating ring 5 is located inside the rotating ring seat 4, and both ends of the first rotating ring 5 abut against the limiting block 40 respectively. The outer wall of the second rotating ring 6 is fixedly connected to the inner wall of the first rotating ring 5. An extension boss 60 is fixedly provided on the second rotating ring 6, and a first release hole 61 is provided on the extension boss 60. A second release hole 12 is provided on the base 1. A hanging claw 71 is fixedly provided at the end of the hook 7, and the hanging claw 71 passes through the first release hole 61 and is inserted into the second release hole 12.

[0067] Example 1 achieves the separation of the secondary connecting rod 9 from the clamp 3, but the clamp 3 and the base 1 are only part of the hemostatic clamp, and there are still other connections between the base 1 and the rest of the hemostatic clamp. This example designs a connection structure between the base 1 and the rest of the hemostatic clamp to ensure that the base 1 and the clamp 3 can be completely released.

[0068] Based on the structural description of this embodiment, the principle by which the base 1 connects and disconnects from the rest of the hemostatic clip is as follows: the rotating ring seat 4 assembles the first rotating ring 5 inside it through the limiting block 40, while still ensuring that the first rotating ring 5 can rotate. The inner wall of the first rotating ring 5 is fixedly connected to the outer wall of the second rotating ring 6 by welding or bonding, or the two are integrally formed. The claw 71 on the hook 7 passes through both the first release hole 61 on the extension boss 60 and the second release hole 12 on the base 1, thereby connecting the second rotating ring 6 to the base 1. Thus, the connection between the rest of the hemostatic clip and the base 1 is achieved.

[0069] The release process of base 1 occurs after the secondary connecting rod 9 disengages from the clamp 3. The transmission rod 2, together with the secondary connecting rod 9, moves axially along base 1 until it abuts against hook 7, exerting a force on hook 7. This force causes the claw 71 to disengage from the second release hole 12 on base 1. Clearly, the connection between base 1 and the second rotating ring 6 relies solely on the engagement of the first release hole 61 and the second release hole 12 with the claw 71. When the claw 71 disengages from the second release hole 12, base 1 and clamp 3 can be released, remaining in the body to clamp the wound. Meanwhile, the transmission rod 2, the two secondary connecting rods 9, the rotating ring seat 4, the first rotating ring 5, the second rotating ring 6, and the hook 7 can leave the body along with the main body of the hemostatic clip. Thus, the remaining parts of the hemostatic clip are detached from base 1.

[0070] Example 3

[0071] Referring to Figures 1-4, the hemostatic clip of this embodiment, compared with the technical solutions of Embodiments 1 or 2, can be improved as follows: It further includes a handle 80, a sliding handle 81, a rotating wheel 82, a plastic-coated spring tube 88, and a spindle 83; the end of the handle 80 is provided with a finger ring 84, and the hook 7 is provided with a through hole 72. The plastic-coated spring tube 88 is sleeved on the outside of the spindle 83, one end of the plastic-coated spring tube 88 is fixedly connected to the end of the handle 80, and the other end of the plastic-coated spring tube 88 is fixedly connected to the rotating ring seat 4. The sliding handle 81 is slidably disposed on the handle 80. One end of the spindle 83 is fixedly connected to the sliding handle 81 through a fixing tube 85, and the other end of the spindle 83 passes through the through hole 72 and is fixedly connected to the transmission rod 2. The rotating wheel 82 is rotatably connected to the handle 80, and a flat part is provided inside the rotating wheel 82. The spindle 83 passes through the flat part and is engaged with the flat part through a guide tube.

[0072] This embodiment, combining embodiments 1 and 2, constitutes a complete hemostatic clip. The handle 80, plastic-coated spring tube 88, rotating ring seat 4, and base 1 are connected sequentially to form the main structure of the hemostatic clip. In this embodiment, the sliding handle 81 and spindle 83, along with other related structures, constitute a traction mechanism capable of pulling the transmission rod 2. That is, the sliding of the sliding handle 81 relative to the handle 80 drives the transmission rod 2 axially via the spindle 83, realizing the opening, closing, locking, and releasing operations of the clamp 3. The rotating wheel 82, through its internal flat portion cooperating with the spindle 83, transmits its rotation to the clamp 3, thereby controlling the rotation of the base 1 and the clamp 3. The finger ring 84 at the end of the handle 80 improves the ease of operation of the hemostatic clip, accommodating more gripping methods.

[0073] The present disclosure and its embodiments have been described above illustratively. This description is not restrictive, and the accompanying drawings are only one embodiment of the present disclosure. The actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present disclosure, such designs should fall within the protection scope of the present disclosure.
