Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a detachable titanium clip assembly and its method of use. Background Technology

[0002] With the development of endoscopic surgery, hemostasis tools have become increasingly diverse, among which titanium clips are the most commonly used. The construction of titanium clips mainly involves pressing pure titanium wire or titanium alloy wire into a V-shaped clamp body. The inner side of the clamping section has transverse grooves to facilitate tissue clamping.

[0003] While titanium clips are medically safe for use in the human body, they can still cause discomfort in some sensitive individuals. In sensitive areas such as the entrance and upper part of the esophagus, the pharynx, and near the anal sphincter, clips can cause a strong foreign body sensation. Furthermore, the mucous membranes in these areas are highly mobile, and the clip's tail can scratch the opposite mucous membrane, leading to bleeding and infection. Therefore, many patients request postoperative removal of titanium clips. Currently, all commercially available titanium clips are either impossible to remove, extremely difficult to remove, or require pulling during removal, which often directly damages human tissue and causes secondary injury to the surgical site. This makes the clinical application of titanium clips less than ideal. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide a detachable titanium clip assembly and a method of using it.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A detachable titanium clip assembly, comprising: The titanium clip body includes two first clamping arms, and a hinge rod is provided between the first clamping arms so that the first clamping arms can open and close along the hinge rod. The tail of the first clamping arm is provided with a connecting rod that can be elastically deformed. The other ends of the connecting rods converge at one point to form a connecting end. The connecting end is provided with a breakable part that can be pulled apart under external force. A sleeve, which is cylindrical, is fitted onto a titanium clip body. By pushing the sleeve onto the titanium clip body, the first clamping arm of the titanium clip body is forced to close. The side of the sleeve is provided with an outwardly protruding annular platform. The inner wall of the sleeve is provided with a sliding groove. Both ends of the hinge rod are placed in the sliding groove. The top of the sliding groove or the inside of the sleeve is provided with a limiting part for limiting the titanium clip body to continue to pull upward. A clamp release device includes a clamp release sheath and a clamp release handle. One end of the clamp release sheath contacts the top of a sleeve. A first traction wire is built into the clamp release sheath. A first clamping part for fingers to grasp or clamp is provided on the clamp release handle. A first movable part for fingers to grasp or clamp is sleeved on the clamp release handle. The first traction wire is connected to the first movable part. The other end of the first traction wire is connected to a breakable part. The first movable part can be pushed up and down relative to the clamp release handle, thereby driving the titanium clamp body to move up and down inside the sleeve. A clamping device includes a clamping sheath and a clamping handle. One end of the clamping sheath is rotatably fitted with a rotating sleeve, and the other end of the clamping sheath is connected to the clamping handle. The rotating sleeve is hinged to two second clamping arms that can clamp together. One end of each second clamping arm forms a claw and is placed outside the rotating sleeve. The other end of each second clamping arm is connected to a second traction line. The clamping handle is provided with a second clamping part for fingers to grasp or hold. The clamping handle is also fitted with a second movable part for fingers to grasp or hold. The second traction line is connected to the second movable part. The second movable part can be pushed up and down relative to the clamping handle. The clamping handle is also provided with a push ring, which is connected to a metal rod. The second clamping arm is provided with a clearance hole at the corresponding position of the metal rod. The metal rod passes through the clamping handle and is placed in the clamping sheath. After the push ring is pushed forward, it can contact the connecting end of the titanium clamp body. The second clamping arm can clamp onto the annular platform of the sleeve and limit the movement of the sleeve.

[0006] Preferably, the cross-section of the annular platform is frustum-shaped, and the bottom area of ​​the annular platform is larger than the top area.

[0007] Preferably, the annular platform can be replaced with an annular groove or a hollowed-out groove.

[0008] Preferably, the top surface of the connecting end of the titanium clip body is a plane.

[0009] Preferably, the first clamping part, the first movable part, the second clamping part, and the second movable part are all provided with a ring for inserting a finger.

[0010] Preferably, both the release sheath and the release sheath are flexible tubes.

[0011] Preferably, both the first and second clamping arms are provided with a return hook at their clamping openings.

[0012] Preferably, a flat plate is provided at the top end of the metal rod.

[0013] A method of using a detachable titanium clip assembly includes the following steps: S1. In the default state, the clamp release device is assembled with the titanium clamp body and the sleeve as one unit, and the titanium clamp body is in a closed state. Operate the clamp release device to keep the first moving part on the clamp release device from moving, and wait for use. S2. Insert the clip releaser along the biopsy channel of the endoscope. When it is pushed to the soft tissue, that is, the first clamping arm of the titanium clip body is placed in the soft tissue, operate the handle of the clip releaser to push the first movable part forward, so that the first clamping arm is gradually pushed out of the sleeve and the first clamping arm is opened. Then push the opened first clamping arm to the soft tissue. Then apply a backward pushing force to the first movable part, and the first traction line will pull the connecting end of the titanium clip body, so that the titanium clip body is gradually pulled back into the sleeve. As the titanium clip body is gradually pulled into the sleeve, the first clamping arm of the titanium clip body will gradually close until the soft tissue is clamped. S3. Once the titanium clip body has clamped the soft tissue, continuing to pull the first traction line will not be able to pull the titanium clip body. At this point, a greater force needs to be applied to the first movable part until the first traction line is broken at the breakable part. S4. After the first traction line is broken, the connection between the release device, the titanium clip body, and the sleeve is released. Then the release device can be removed from the biopsy channel of the endoscope, while the titanium clip body holding the soft tissue remains in place under the action of the sleeve. S5. When it is necessary to remove the titanium clip body, simply push the endoscope to the titanium clip body, and then insert the clamp remover from the biopsy channel of the endoscope, keeping the push ring at the outermost end and keeping the metal rod retracted at the clearance hole. S6. Place the second clamping arm of the clamping device on the annular platform of the sleeve, then push the second movable part forward to open the second clamping arm and press it against the annular platform. Then push the second movable part in the opposite direction to clamp the second clamping arm on the annular platform and keep the second movable part from moving. S7. After the second clamping arm holds the annular platform, the external force pushes the push ring forward, causing the metal rod to gradually push out of the clearance hole and touch the connecting end of the titanium clip body. As the push ring continues to be pushed, the titanium clip body will be pushed out of the sleeve, thereby causing the titanium clip body to be released from the clamping of the soft tissue. In this way, the titanium clip body and the sleeve can be removed from the human body by relying on the second clamping arm of the clamp remover.

[0014] By adopting the above-mentioned solution, this invention, without affecting the clamping structure of conventional titanium clips, relies on setting an annular platform on the sleeve and combining the use of a clip releaser and a clip releaser to create a linkage between the titanium clip body and the sleeve. With the cooperation of the first clamping arm, the titanium clip body can be easily clamped to hold soft tissue, and the easily breakable part can be separated from the titanium clip body under external force, achieving separation between the clip releaser and the titanium clip body. At the same time, when it is necessary to remove the titanium clip body inside the human body, the second clamping arm on the clip releaser and the metal rod can be used to quickly remove the titanium clip. This installation and removal method is simple to operate, can be directly completed through an endoscope, and can effectively avoid secondary damage to the human body during the removal process.

[0023] like Figures 1 to 5 As shown, this embodiment provides a detachable titanium clip assembly, comprising: The titanium clamp body 1 includes two first clamping arms 11, and a hinge rod 12 is provided between the first clamping arms 11 so that the first clamping arms 11 can open and close along the hinge rod 12. The tail of the first clamping arm 11 is provided with a connecting rod 13 that can be elastically deformed. The other ends of the connecting rod 13 converge at one point to form a connecting end 14. The connecting end 14 is provided with a breakable part 15 that can be broken under external force. Alternatively, the connecting rod 13 is rigid, and the two ends of the connecting rod 13 are connected to the tail of the first clamping arm 11 and the connecting end 14 by hinge. Sleeve 2, which is cylindrical, is sleeved on the titanium clamp body 1. By pushing the sleeve 2 on the position of the titanium clamp body 1, the first clamping arm 11 of the titanium clamp body 1 is forced to close. The side of the sleeve 2 is provided with an outwardly protruding annular platform 21. The inner wall of the sleeve 2 is provided with a sliding groove 22. The two ends of the hinge rod 12 are placed in the sliding groove 22. The top of the sliding groove 22 or the inside of the sleeve 2 is provided with a limiting part 23 for limiting the titanium clamp body 1 to continue to pull upward. The clamp release device 3 includes a clamp release sheath 31 and a clamp release handle 32. One end of the clamp release sheath 31 contacts the sleeve 2. The clamp release sheath 31 has a first traction wire 33 inside. The clamp release handle 32 is provided with a first clamping part 34 for fingers to grasp or clamp. The clamp release handle 32 is sleeved with a first movable part 35 for fingers to grasp or clamp. The first traction wire 33 is connected to the first movable part 35. The other end of the first traction wire 33 is connected to the breakable part 15. The first movable part 35 can be pushed up and down relative to the clamp release handle 32, thereby driving the titanium clamp body 1 to move up and down inside the sleeve 2. The clamping device 4 includes a clamping sheath 41 and a clamping handle 42. One end of the clamping sheath 41 is rotatably fitted with a rotating sleeve 43, and the other end of the clamping sheath 41 is connected to the clamping handle 42. The rotating sleeve 43 is hinged to two second clamping arms 44 capable of clamping. One end of each second clamping arm 44 forms a claw portion and is positioned outside the rotating sleeve 43. The other end of each second clamping arm 44 is connected to a second traction line 45. The clamping handle 42 is provided with a second clamping part 46 for fingers to grasp or hold. The second movable part 47 is connected to the second traction line 45. The second movable part 47 can be pushed up and down relative to the clamping handle 42. The clamping handle 42 is also provided with a push ring 48. The push ring 48 is connected to a metal rod 49. The second clamping arm 44 is provided with a clearance hole 401 at the corresponding position of the metal rod 19. The metal rod 49 passes through the clamping handle 42 and is placed in the clamping sheath tube 41. After the push ring 48 is pushed forward, it can contact the connecting end 14 of the titanium clamp body 1. The second clamping arm 44 can clamp at the annular platform 21 of the sleeve 2 and limit the movement of the sleeve 2.

[0024] This embodiment mainly relies on the annular platform 21 set on the sleeve 2, and the use of the clamp release device 3 and the clamp lifter 4, to form a linkage between the titanium clip body 1 and the sleeve 2 without affecting the clamping structure of the conventional titanium clip. With the cooperation of the first clamping arm 11, the titanium clip body 1 can be easily clamped to hold soft tissue, and the connection between the clamp release device 3 and the titanium clip body 1 can be separated by the easily broken part 15 under the action of external force. At the same time, when it is necessary to remove the titanium clip body 1 from the human body, the second clamping arm 44 and the metal rod 49 on the clamp lifter 4 can be used to quickly remove the titanium clip. This installation and removal method is simple to operate, can be directly completed through the endoscope, and can effectively avoid secondary damage to the human body during the removal process.

[0025] Furthermore, to better allow the second clamping arm 44 to grip the sleeve 2, the cross-section of the annular platform 21 in this embodiment is frustoconical, with the bottom area of ​​the annular platform 21 being larger than the top area. This creates a horizontal surface at the lower end of the annular platform 21, providing sufficient area for gripping. Since the annular platform 21 is a complete circle, it can be directly gripped regardless of the position of the second clamping arm 44 during actual operation. The maximum protruding diameter of the annular platform 21 is less than 3.6 mm. The annular platform 21 can be replaced by an annular groove or a hollowed-out groove. The annular groove can be a single ring or have three recessed positions, while the hollowed-out groove is formed by multiple hollowed-out sections arranged in a ring.

[0026] Furthermore, to facilitate the metal rod 49 pushing against the titanium clamp body 1, the top surface of the connecting end 14 of the titanium clamp body 1 in this embodiment is a flat surface. This provides sufficient area for the metal rod 49 to make contact and also prevents slippage when the metal rod 49 pushes against the clamp body 1. Additionally, a flat plate 402 is provided at the top of the metal rod 49. This double-plane design effectively ensures that the metal rod 49 can properly push against the titanium clamp body 1. The flat plate 402 can be a cone shape, thickening approximately 15mm from the metal rod to transmit force without deformation. When the second clamping arms 44 are closed, the flat plate 402 is positioned between the two clamping arms 44.

[0027] Furthermore, to facilitate the doctor's operation, the first clamping part 34, the first movable part 35, the second clamping part 46, and the second movable part 47 in this embodiment are all provided with a ring 100 for finger insertion.

[0028] Furthermore, in this embodiment, both the release sheath 31 and the release sheath 41 are flexible tubes.

[0029] Furthermore, to make the clamping of the first clamping arm 11 and the second clamping arm 44 more secure, hooks are provided at the clamping openings of the first clamping arm 11 and the second clamping arm 44 in this embodiment. The hooks are used to clamp the soft tissue and the annular platform 21, which makes it more secure. The specific shape of the hooks can be "L" shaped or spoon-shaped. This embodiment does not limit the specific structure of the hooks.

[0030] This embodiment describes a method for using a detachable titanium clip assembly, specifically including the following steps: S1. In the default state, the clamp releaser 3 is assembled with the titanium clamp body 1 and the sleeve 2 as one unit, and the titanium clamp body 1 is in a closed state. Operate the clamp releaser 3 to keep the first movable part 35 on the clamp releaser 3 from moving, and wait for use. S2. Insert the clip releaser 3 along the biopsy channel of the endoscope. When it is pushed to the soft tissue, that is, the first clamping arm 11 of the titanium clip body 1 is placed in the soft tissue, operate the handle 32 of the clip releaser 3 to push the first movable part 35 forward, so that the first clamping arm 11 is gradually pushed out of the sleeve 2 and the first clamping arm 11 is opened. Then push the opened first clamping arm 11 to the soft tissue. Then, give the first movable part 35 a backward pushing force, and the first traction line 33 will pull the connecting end 14 of the titanium clip body 1, so that the titanium clip body 1 is gradually pulled back into the sleeve 2. As the titanium clip body 1 is gradually pulled into the sleeve 2, the first clamping arm 11 of the titanium clip body 1 will gradually close until the soft tissue is clamped. S3. When the titanium clip body 1 clamps the soft tissue, due to the presence of the limiting part 23, continuing to pull the first traction line 33 will not be able to pull the titanium clip body 1. At this time, a greater force needs to be applied to the first movable part 35 until the first traction line 33 is broken at the easily broken part 15. S4. After the first traction line 33 is broken, the clamp release device 3 is disconnected from the titanium clamp body 1 and the sleeve 2. Then the clamp release device 3 can be removed from the biopsy channel of the endoscope, and the titanium clamp body 1, which is holding the soft tissue, maintains the clamping of the soft tissue under the action of the sleeve 2. S5. When it is necessary to remove the titanium clip body 1, simply push the endoscope to the titanium clip body 1, and then insert the clamp remover 4 from the biopsy channel of the endoscope, wherein the push ring 48 is kept at the outermost end, and the metal rod 49 is kept retracted at the clearance hole 401. S6. Place the second clamping arm 44 of the clamping device 4 at the annular platform 21 of the sleeve 2, then push the second movable part 47 forward to open the second clamping arm 44 and press it against the annular platform 21. Then push the second movable part 47 in the opposite direction to clamp the annular platform 21 with the second clamping arm 44 and keep the second movable part 47 from moving. S7. After the second clamping arm 44 clamps the annular platform 21, the external force pushes the push ring 48 forward, causing the metal rod 49 to gradually push out of the clearance hole 401 and touch the connecting end 14 of the titanium clip body 1. As the push ring 48 is pushed further, the titanium clip body 1 will be pushed out of the sleeve 2, thereby allowing the titanium clip body 1 to be released from the clamping of the soft tissue. In this way, the titanium clip body 1 and the sleeve 2 can be removed from the human body by relying on the second clamping arm 44 of the clamp remover 4.

[0031] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural or procedural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
