Description

Technical Field

[0001] The present invention relates to medical instruments, in particular to a hemostatic clip for an endoscope. Background Art

[0002] When using a hemostatic clamp, the surgeon uses an endoscope to clamp the clamp to the tissue and release it into the patient's body, closing the wound. After a period of time, the clamp assembly will fall off and be excreted from the body through the digestive tract. Obviously, the shorter the clamp assembly that remains in the patient's body, the better. A longer clamp assembly may damage the digestive tract mucosa.

[0003] In this regard, Chinese patent publication number CN110464410A discloses a clamping device and its clamping part for use with an endoscope. The solution adopted is: by connecting the tail of the clip with the release part, the space is maximized, and the total length is the shortest after the clamp is released; the defect is that the protrusion at the tail of the clip needs to be buckled on the stop step of the clamp tube to lock the clip, and the protrusion is located at the tail end of the clip, so the required length of the clamp tube is bound to be longer, resulting in a longer remaining length after the clamp is released. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to solve the problem that the hemostatic clip in the prior art remains for a long time after clamping and releasing, which may damage the digestive tract mucosa and is difficult to be expelled from the body.

[0005] The technical solution adopted by the present invention to solve the technical problem is: an endoscope hemostatic clip, comprising an operating component and a clamp assembly, the clamp assembly comprising:

[0006] An outer sleeve, used for fixed connection with the operating component;

[0007] A clamp is arranged on the front side of the outer sleeve, and the clamp has an accommodating cavity inside, and a locking hole is opened on the inner wall of the accommodating cavity;

[0008] The chuck has two elastic clamping arms, the front end of the clamping arm is the clamping end, the rear end of the clamping arm is the push-pull end, the middle part of at least one clamping arm is provided with an elastic locking tongue, the clamping end is located outside the accommodating cavity, and the push-pull end is movably arranged in the accommodating cavity, the rear end of the locking tongue is connected to the clamping arm, and the front end of the locking tongue is suspended in the air, the push-pull end of the chuck is detachably connected to the operating component, and the operating component can push the chuck forward to move the clamping ends of the two clamping arms away from each other, and can pull the chuck backward to move the clamping ends of the two clamping arms closer to each other;

[0009] A limiting sleeve, one end of which is inserted into the accommodating cavity to connect with the clamp, and the other end of which is inserted into the outer sleeve;

[0010] And an elastic element is used to push the limiting sleeve forward so that it is elastically limited in the working position. When the limiting sleeve is in the working position, it presses the locking tongue to prevent the locking tongue from rebounding into the locking hole. The limiting sleeve is driven backward by the clamping head to leave the working position, and when the front end of the locking tongue moves to be aligned with the locking hole, the front end of the locking tongue rebounds into the locking hole, so that the clamping ends of the two clamping arms continue to clamp human tissue.

[0011] Furthermore, when the limiting sleeve is located at the working position, it at least blocks a portion of the locking hole.

[0012] Furthermore, the operating component includes a spring tube, a cable and a handle assembly. The cable passes through the spring tube and the limiting sleeve and is detachably connected to the chuck. The handle assembly is used to drive the chuck to move forward and backward through the cable. The outer sleeve is fixedly connected to the spring tube.

[0013] Furthermore, the outer sleeve has a front hole and a rear hole connected to each other, the rear end of the front hole is connected to the front end of the rear hole, the cross-sectional area of ​​the front hole is larger than the cross-sectional area of ​​the rear hole, so that the connection between the front hole and the rear hole forms an inner step surface;

[0014] The limiting sleeve has a thin section and a thick section that are connected to each other. The rear end of the thin section is connected to the front end of the thick section. The cross-sectional area of ​​the thin section is smaller than that of the thick section, so that an outer step surface is formed at the connection between the thin section and the thick section.

[0015] The thick section is located in the rear hole, the elastic element pushes the thick section forward so that the outer step surface abuts against the inner step surface, and the thin section passes through the front hole and is inserted into the accommodating cavity.

[0016] Furthermore, the front hole and the rear hole are coaxially arranged, the outer peripheral wall of the thick section is coaxial with the inner peripheral wall of the rear hole and contacts each other; the outer peripheral wall of the thin section is coaxial with the inner peripheral wall of the accommodating cavity and contacts each other.

[0017] Furthermore, one end of the elastic element abuts against the front end of the spring tube, and the other end abuts against the rear end of the thick section.

[0018] Furthermore, the front end of the spring tube extends into the rear hole of the outer sleeve.

[0019] Furthermore, the elastic element is a compression spring.

[0020] Furthermore, the push-pull ends of the two clamping arms are integrally connected to form a connecting section, and a detachable structure is fixed to the front end of the cable, and the detachable structure has a first side wing, a second side wing and a slot between the first side wing and the second side wing, one end of the first side wing is fixedly connected to one end of the second side wing, and an opening connected to the slot is formed between the other end of the first side wing and the other end of the second side wing, and the connecting section is stuck in the slot.

[0021] Furthermore, the locking tongue is formed by stamping at the middle portion of the clamping arm.

[0022] The beneficial effects of the present invention are as follows: the hemostatic clamp for endoscope of the present invention adopts the design of elastically retractable limiting sleeve in combination with the chuck, which can, on the one hand, limit the clamp to the front end of the outer sleeve and simplify the structure of the clamp, and on the other hand, prevent the locking tongue from rebounding into the locking hole in advance, thereby ensuring that the chuck can be opened repeatedly; the installation of the clamp and the prevention of the locking tongue from being stuck in the locking hole in advance are all achieved by the limiting sleeve, combined with the locking tongue design in the middle part of the clamp arm, thereby greatly shortening the length of the clamp, and after release, the total length of the chuck and the clamp remaining in the body is short, thereby reducing the risk of damaging the digestive tract mucosa caused by the chuck assembly remaining in the body for too long.

[0041] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams that illustrate the basic structure of the present invention only in a schematic manner. Therefore, they only show components relevant to the present invention, and directions and references (e.g., up, down, left, right, etc.) may be used solely to facilitate the description of features in the drawings. The following detailed description is therefore not to be taken in a limiting sense, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0042] like Figure 1-7 As shown, a hemostatic clip for endoscope has an operating component and a chuck assembly, wherein the chuck assembly includes an outer sleeve 1, a clamp 2, a chuck 3, a limiting sleeve 4 and an elastic element 5;

[0043] The outer sleeve 1 is used for fixed connection with the operating component;

[0044] The clamp 2 is arranged on the front side of the outer sleeve 1. The clamp 2 has an accommodating cavity 21 inside. The inner wall of the accommodating cavity 21 is provided with a locking hole 211. The locking hole 211 can be a through hole or a blind hole.

[0045] The clamping head 3 has two elastic clamping arms 31, the front end of the clamping arm 31 is the clamping end 31a, the rear end of the clamping arm 31 is the push-pull end 31b, and the middle part of at least one clamping arm 31 is provided with an elastic locking tongue 311, the clamping end 31a is located outside the accommodating cavity 21, and the push-pull end 31b is movably arranged in the accommodating cavity 21, the rear end of the locking tongue 311 is connected to the clamping arm 31, and the front end of the locking tongue 311 is suspended in the air; the middle part of the two clamping arms 31 can be provided with a locking tongue 311, and two locking holes 211 are correspondingly opened on the inner wall of the accommodating cavity 21, and each locking tongue 311 is provided with a locking tongue 311. 11 corresponds to a locking hole 211, and the locking hole 211 is for the corresponding locking tongue 311 to be snapped in; the push-pull end 31b of the clamp 3 is detachably connected to the operating component. When the operating component pulls the clamp 3 backward to enter the accommodating cavity 21, the clamping hoop 2 will press the clamping ends 31a of the two clamping arms 31 to move closer to each other, forming a closed state; when the operating component pushes the clamp 3 forward to leave the accommodating cavity 21, the clamping arms 31 gradually lose the constraint of the clamping hoop 2 and, under the action of their own elastic force, the clamping ends 31a of the two clamping arms 31 of the clamp 3 move away from each other, forming an open state;

[0046] One end of the limiting sleeve 4 is inserted into the accommodating cavity 21 to connect the limiting sleeve 4 to the clamp 2, and the other end of the limiting sleeve 4 is inserted into the outer sleeve 1;

[0047] The elastic element 5 is used to push the limiting sleeve 4 forward so that it is elastically limited in the working position. When the limiting sleeve 4 is in the working position, it will press the locking tongue 311 to prevent the locking tongue 311 from rebounding into the locking hole 211. The limiting sleeve 4 is driven backward by the clamping head 3 and leaves the working position. When the front end of the locking tongue 311 moves to be aligned with the locking hole 211, the front end of the locking tongue 311 rebounds into the locking hole 211, so that the clamping ends 31a of the two clamping arms 31 continue to clamp the human tissue.

[0048] The hemostatic clamp for endoscope adopts the design of elastically retractable limiting sleeve 4 and chuck 3, which can limit the clamp 2 to the front end of the outer sleeve 1 and simplify the structure of the clamp 2, and can prevent the locking tongue 311 from rebounding into the locking hole 211 in advance, so as to ensure that the clamp 3 can be opened repeatedly; the installation of the clamp 2 and the prevention of the locking tongue 311 from being stuck in the locking hole 211 in advance are all achieved by the limiting sleeve 4, combined with the design of the locking tongue 311 in the middle part of the clamp arm 31, so that the length of the clamp 2 can be greatly shortened, and after being released, the clamp 2 can be left The total length of the chuck 3 and the clamp 2 in the body is short, so as to reduce the risk of damaging the digestive tract mucosa due to the chuck assembly remaining in the body for too long; when the operator confirms that the chuck 3 needs to be locked in the closed state, the operating part pulls the chuck 3 backward, and the chuck 3 drives the limiting sleeve 4 to move backward. After the limiting sleeve 4 leaves the working position, once the front end of the locking tongue 311 moves to align with the locking hole 211, the front end of the locking tongue 311 will immediately pop into the locking hole 211, thereby realizing that the chuck 3 is automatically locked in the closed state by the clamp 2.

[0049] In some examples, when the limiting sleeve 4 is in the working position, it at least blocks a portion of the locking hole 211. By the limiting sleeve 4 occupying the locking hole 211, the chuck 3 must push the limiting sleeve 4 out of the working position before the locking tongue 311 can be engaged with the locking hole 211, further ensuring that the chuck 3 can be opened repeatedly.

[0050] In some examples, the operating components include a spring tube 6, a cable 7 and a handle assembly 8. The cable 7 passes through the spring tube 6 and the limiting sleeve 4. The cable 7 is detachably connected to the chuck 3, that is, when the tension of the cable 7 reaches a certain value, it automatically separates from the chuck 3. The outer sleeve 1 is fixedly connected to the spring tube 6, for example, the outer sleeve 1 and the spring tube 6 are welded and fixed; the handle assembly 8 is used to drive the chuck 3 to move forward and backward through the cable 7; for example, the handle assembly 8 has a handle 81 and a slip ring 82, the slip ring 82 is slidably connected to the handle 81, the rear end of the spring tube 6 is connected to the front end of the handle 81, and the rear end of the cable 7 is fixed to the slip ring 82 The sliding ring 82 can be connected with the clamp 3 by the pull rope 7, and the clamp 3 can be moved forward and backward along the handle 81. When the sliding ring 82 drives the clamp 3 to move backward through the pull rope 7, the clamp 3 will gradually shrink into the accommodating cavity 21, that is, the clamping hoop 2 forces the clamping ends 31a of the two clamping arms 31 to gradually move closer, so that the clamping ends 31a of the two clamping arms 31 of the clamp 3 clamp the tissue in a closed state; when the sliding ring 82 drives the clamp 3 to move forward through the pull rope 7, the clamping arms 31 gradually lose the constraint of the clamping hoop 2 and under the action of their own elastic force, the clamping ends 31a of the two clamping arms 31 of the clamp 3 move away from each other and are in an open state.

[0051] In some examples, the outer sleeve 1 has a front hole 11 and a rear hole 12 that are connected to each other, the rear end of the front hole 11 is connected to the front end of the rear hole 12, and the cross-sectional area of ​​the front hole 11 is larger than the cross-sectional area of ​​the rear hole 12, so that an inner step surface 13 is formed at the connection between the front hole 11 and the rear hole 12, which facilitates the forward and backward movement of the limiting sleeve 4 in the outer sleeve 1.

[0052] The limiting sleeve 4 has a thin section 41 and a thick section 42 that are connected to each other. The rear end of the thin section 41 is connected to the front end of the thick section 42. The cross-sectional area of ​​the thin section 41 is smaller than that of the thick section 42, so that an outer step surface 43 is formed at the connection between the thin section 41 and the thick section 42.

[0053] The thick section 42 is located in the rear hole 12, and the elastic element 5 pushes the thick section 42 forward so that the outer step surface 43 abuts against the inner step surface 13. The thin section 41 passes through the front hole 11 and is inserted into the accommodating cavity 21. When the outer step surface 43 abuts against the inner step surface 13, the limiting sleeve 4 is in the working position; the above structural design can realize the elastic telescopic movement of the limiting sleeve 4.

[0054] In some examples, the front hole 11 and the rear hole 12 are coaxially arranged, and the outer peripheral wall of the thick section 42 is coaxial with the inner peripheral wall of the rear hole 12 and contacts each other, so that the limiting sleeve 4 can be slidably installed in the outer sleeve 1 along its axial direction to prevent the limiting sleeve 4 from shaking; the outer peripheral wall of the thin section 41 is coaxial with the inner peripheral wall of the accommodating cavity 21 and contacts each other, which can improve the stability of the installation of the clamp 2, and the thin section 41 can also be slightly interference fit with the accommodating cavity 21, which can further improve the stability of the installation of the clamp 2.

[0055] In some examples, one end of the elastic element 5 rests against the front end of the spring tube 6, and the other end rests against the rear end of the thick section 42; this allows for sufficient space to install the elastic element 5, and simplifies the installation structure of the elastic element 5. The elastic element 5 may be, but is not limited to, a compression spring, and the elastic element 5 may be located in the rear hole 12 of the outer sleeve 1.

[0056] In some examples, the front end of the spring tube 6 extends into the rear hole 12 of the outer sleeve 1 , which can improve the connection strength between the outer sleeve 1 and the spring tube 6 .

[0057] In some examples, the push-pull ends 31b of the two clamping arms 31 are integrally formed and connected to form a connecting section 312. A detachable structure 9 is fixed to the front end of the cable 7. The detachable structure 9 has a first side wing 91, a second side wing 92, and a slot 93 between the first side wing 91 and the second side wing 92. One end of the first side wing 91 is fixedly connected to one end of the second side wing 92. An opening 94 communicating with the slot 93 is formed between the other end of the first side wing 91 and the other end of the second side wing 92. The connecting section 312 is stuck in the slot 93. When the tension applied to the detachable structure 9 causes the first side wing 91 and the second side wing 92 to deform, the connecting section 312 leaves the slot 93 from the opening 94, thereby realizing the separation of the cable 7 and the chuck 3. The connecting section 312 of the chuck 3 is stuck in the slot 93 of the detachable structure 9 at the front end of the cable 7. The thin section 41 of the limiting sleeve 4 is inserted into the accommodating cavity 21 so that the accommodating cavity 21 and the thin section 41 are coaxially arranged. The chuck 3 then cooperates with the outer sleeve 1 to fix the front and rear positions of the clamp 2.

[0058] In some examples, the material of the clamp arm 31 can be but is not limited to metal. The middle part of the clamp arm 31 is stamped to form the lock tongue 311, thereby eliminating the need for assembly between the lock tongue 311 and the clamp arm 31, and ensuring the strength of the lock tongue 311. At the same time, the structure is simple and the cost can be reduced.

[0059] The working process of the above-mentioned hemostatic clip for tissue clamping is as follows:

[0060] Initially, a relatively small force is required to push the cable 7 forward or pull it backward to repeatedly open the chuck 3. During this process, the limiting sleeve 4 presses the locking tongue 311 to prevent the locking tongue 311 from tilting up or rebounding into the locking hole 211.

[0061] When the surgeon confirms that the clamp 3 needs to be locked in the closed state, the surgeon pulls the cable 7 backward by moving the slip ring 82 on the handle assembly 8. The cable 7 drives the clamp 3 backward into the accommodating cavity 21 of the clamp 2. The clamping ends 31a of the two clamp arms 31 gradually move closer to clamp the human tissue.

[0062] Increase the tension applied to the slip ring 82 so that the chuck 3 presses against the hollow thin section 41 of the limiting sleeve 4, and a portion of the rear end of the chuck 3 can extend into the thin section 41 of the limiting sleeve 4;

[0063] Next, the operator continues to pull the cable 7 backward, and the cable 7 drives the limiting sleeve 4 to move backward through the chuck 3, so that the limiting sleeve 4 leaves the working position. During this process, the elastic element 5 is gradually compressed by the limiting sleeve 4, and once the front end of the locking tongue 311 moves to align with the locking hole 211, the front end of the locking tongue 311 will immediately spring into the locking hole 211, so that the clamp 2 automatically locks the chuck 3 in the closed state;

[0064] Finally, continue to pull the cable 7 backward. When the tension on the detachable structure 9 causes the first side wing 91 and the second side wing 92 to deform, the connecting section 312 leaves the slot 93 at the opening 94, thereby separating the cable 7 from the chuck 3. The chuck 3 is released, and the limiting sleeve 4, the outer sleeve 1 and the elastic element 5 are detached together under the drive of the handle assembly 8.

[0065] The above description of the preferred embodiments of the present invention is intended to serve as a guide. Based on the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
