[0003] For example, the patent document with the authorization announcement number CN219814223U and the authorization announcement date October 13, 2023, and named "A hemostatic clip", includes a chuck assembly, a conveyor and a connecting assembly; the chuck assembly includes a pair of clips and a sleeve that can partially accommodate the clips; the conveyor includes a spring tube, a connecting sleeve connected to the front end of the spring tube, a handle assembly connected to the rear end of the spring tube, and a rotatable pull rod shaft that passes through the inside of the spring tube, the front end of the pull rod shaft is connected to a pair of clips, and the rear end of the pull rod shaft is connected to the handle assembly; this patent can be used for flexible rotation and accurate angle adjustment of the gastrointestinal endoscope, so that the doctor can quickly and accurately adjust the angle between the clamp and the lesion, and better clamp the lesion.

[0004] A typical hemostatic clip generally includes a clamping part, an introduction part and an operating part. The clamping part needs to be separated from the introduction part after closing at the marked position. The separation method in the prior art is generally to set a deformable structure at the proximal end of the clamping part, and the clamping part can be separated by deforming and destroying the deformable structure through the force transmitted by the introduction part. This method has a relatively complex structure, and the cost of instrument manufacturing and quality control will increase. Summary of the invention

[0005] The object of the present invention is to provide a locking and detaching integrated hemostatic clip to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A locking and detaching integrated hemostatic clip, comprising a clip and a tightening tube, and also comprising:

[0008] A push-pull block located in the tightening tube;

[0009] A clamping piece is formed at the proximal end of the clip, and the clamping piece has a first state of clamping the push-pull block and a second state of clamping the tight tube in the movement stroke. In the first state, the push-pull block drives the clip to perform a closing stroke on the target tissue, and in the second state, the push-pull block is separated from the clamping piece.

[0010] In the above-mentioned one-piece locking and detaching hemostatic clip, the clip is structured in a V-shape and is elastic.

[0011] In the above-mentioned one-piece locking and detaching hemostatic clip, the inner wall of the tightening tube is configured with a groove.

[0012] In the above-mentioned one-piece locking and detaching hemostatic clip, a clamping block is provided on the clamping component.

[0013] In the above-mentioned one-piece locking and detaching hemostatic clip, the clamping member is U-shaped and elastic.

[0014] In the above-mentioned one-piece locking and detaching hemostatic clip, a pull rod shaft is fixed to the proximal end of the push-pull block.

[0015] In the above-mentioned one-piece locking and detaching hemostatic clip, a fastening mechanism for forcing the clamping block to be confined in the groove is arranged in the tightening tube.

[0016] The above-mentioned one-piece locking and detachable hemostatic clip, the fastening mechanism comprises a fastening ring elastically connected in the groove, and the fastening ring is configured with a wedge-shaped surface.

[0017] The above-mentioned locking and detachable integrated hemostatic clip, the fastening mechanism includes a wedge block slidably connected in the tightening tube, and the wedge block has a first position close to the proximal end and a second position close to the distal end.

[0018] In the above-mentioned one-piece locking and detaching hemostatic clip, when the push-pull block is separated from the clamping member, the wedge block switches from the first position to the second position.

[0019] In the above technical scheme, the present invention provides a locking and detachable integrated hemostatic clamp, which can clamp the push-pull block through the first state of the clamping piece, so that the push-pull block can drive the clamp and the clamping piece to move in the tightening tube to close the target tissue. After the clamp closes the target tissue, the clamping piece switches to the second state to clamp the tightening tube. At this time, the relative positions of the clamp and the tightening tube are locked to stably close the target. At the same time, the push-pull block loses the clamping and can be separated from the clamping piece. In this way, through a simple structure, the required clamping, closing, separation and locking functions can be achieved in one step, thereby reducing the cost of device manufacturing and quality control costs.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] In each embodiment provided by the present invention, proximal end and distal end are professional terms in the medical field. For various endoscopes and other catheters and guidewire-type medical devices that need to enter the human body, "proximal end" and "distal end" refer to the relative orientation, relative position, and direction of components or actions relative to each other from the perspective of a doctor using the medical device. The proximal end refers to the end close to the doctor, and the distal end refers to the end far from the doctor. This standard is followed in each embodiment of the present invention.

[0032] Reference Figure 1-7The embodiment of the present invention provides a locking and detaching integrated hemostatic clip, comprising a clip 1 and a tightening tube 2, and also comprising a push-pull block 3 and a clamping member 4. The push-pull block 3 is located in the tightening tube 2; the clamping member 4 is fixed to the proximal end of the clip 1, and the clamping member 4 is formed at the proximal end of the clip 1. The clamping member 4 has a first state of clamping the push-pull block 3 and a second state of clamping the tightening tube 2 in the movement stroke. In the first state, the push-pull block 3 drives the clip 1 to perform a closing stroke on the target tissue, and in the second state, the push-pull block 3 is separated from the clamping member 4. The clip 1 is constructed in a V-shape and has elasticity.

[0033] Specifically, the overall structure of the clip 1 is V-shaped, and a clamping claw structure is generally provided on its two open ends to clamp and close the target tissue when the two open ends of the clip 1 are close to each other; the target tissue is the blood vessel or flesh tissue that needs to be closed; the clip 1 itself has elasticity to force its two open ends to move away from each other, and when the clip 1 moves out of the tightening tube 2, the two open ends of the clip 1 open under the action of their own elastic force, and when the clip 1 moves to the target position, the clip 1 is relatively retracted into the tightening tube 2, and the inner wall of the tightening tube 2 can force the clip 1 to overcome its own elastic force, so that the two open ends of the clip 1 are close to each other, and then the target tissue is clamped and closed by the clip 1; the clip 1 and The tightening tube 2 is generally used in combination with an introduction component and an operating component. The clip 1, tightening tube 2 and introduction component can enter the patient's body through the endoscopic forceps channel, so that the clip 1 and tightening tube 2 reach the predetermined surgical position in the patient's body, and then the surgical action is performed through the operating component. The implemented surgical action is transmitted to the clip 1 through the introduction component, so that the clip 1 produces an action response, and the surgical wound is hemostatic or clamped. Then, the clip 1 and tightening tube 2 structure are separated (separated from the introduction component) through the operating component, so that the clip 1 and tightening tube 2 remain in the patient's body, clamp the blood vessels and surrounding tissues (that is, the target tissue), and achieve the therapeutic purpose of hemostasis; the above are all existing technologies and will not be repeated here. The innovation of the embodiment of the present invention is that a clamping member 4 is arranged in the tightening tube 2. The clamping member 4 can use a clamping structure in the prior art, which can change its state (such as rotating or moving the clamping part arranged at the proximal end of the clamp 1) to clamp the push-pull block 3 (the push-pull block 3 is a part of the above-mentioned introduction component) or the tightening tube 2. When the clamping member 4 is in the first state, the push-pull block 3 is clamped. At this time, the push-pull block 3 can control the clamp 1 and the clamping member 4 to move synchronously in the tightening tube 2, so that the clamp 1 can clamp the target tissue when it is received in the tightening tube 2. The clamping member 4 is held closed. After completing the clamping closure of the target tissue, the clamping member 4 switches to the second state to clamp the inner wall of the tightening tube 2. At this time, the clamping member 4 releases the clamping of the push-pull block 3, so that the push-pull block 3 can be moved out of the patient's body along with the introduction component. At the same time, the clamping member 4 clamps the tightening tube 2, thereby locking the relative positions of the clip 1 and the tightening tube 2 to stably close the target tissue. Through a simple structure, the required clamping, closing, separation and locking functions are achieved in one step, reducing the cost of device manufacturing and quality control costs.

[0034] The embodiment of the present invention provides a locking and detachable integrated hemostatic clip, in which the push-pull block 3 can be clamped by the clamping piece 4 in the first state, so that the push-pull block 3 can drive the clip 1 and the clamping piece 4 to move in the tightening tube 2 to close the target tissue. After the clip 1 closes the target tissue, the clamping piece 4 switches to the second state to clamp the tightening tube 2. At this time, the relative positions of the clip 1 and the tightening tube 2 are locked to stably close the target. At the same time, the push-pull block 3 loses the clamping and can be separated from the clamping piece 4. In this way, the required clamping, closing, separation and locking functions can be achieved through a simple structure and one-step operation, thereby reducing the cost of device manufacturing and quality control costs.

[0035] In another embodiment provided by the present invention, further, the inner wall of the tightening tube 2 is configured with a groove 5. Specifically, the clip 1 and the groove 5 are respectively located at the two ends of the tightening tube 2, and the inner diameter of the groove 5 is larger than the inner diameter of the tightening tube 2. After the clip 1 clamps and closes the target tissue, the clamping member 4 is clamped into the groove 5 to clamp the tightening tube 2. At this time, the clamping member 4 at the proximal end of the clip 1 is restricted by the groove 5 and cannot move to the distal end, that is, the clip 1 cannot move out of the tightening tube 2 to the distal end, and then the target tissue is stably closed by the clip 1.

[0036] Preferably, a clamping block 6 is provided on the clamping member 4. The clamping member 4 is constructed in a U shape and is elastic. Specifically, the connection method of the clamping block 6 and the clamping member 4 can be selected from a rotating connection or a sliding connection, so as to clamp the push-pull block 3 or the tightening tube 2 through the clamping blocks 6 at different positions. Preferably, the clamping member 4 is constructed in a U shape as a whole, and clamping blocks 6 are fixed on its two open ends. Under the elastic force of the clamping member 4 itself, the two open ends can be forced to move away from each other, and the push-pull block 3 is located in the U-shaped opening of the clamping member 4; when the clamp 1 does not clamp and close the marked tissue, the clamping blocks 6 at the two open ends of the clamping member 4 can be forced to move closer to each other through the inner wall of the tightening tube 2, so that the opening of the U-shaped structure of the clamping member 4 can be closed, thereby clamping the push-pull block 3, so that the push-pull block 3 can be brought into contact when pushed and pulled by the introduction component. The movable clamp 1 moves in the tightening tube 2, thereby driving the clamp 1 to clamp and close the target tissue, which is the first state of the clamping piece 4; after the push-pull block 3 drives the clamp 1 to clamp and close the target tissue, the clamping block 6 moves synchronously to the groove 5 position. At this time, under the elastic force of the clamping piece 4, the two clamping blocks 6 move away from each other and abut against the inner wall of the groove 5, so that the clamping block 6 is embedded in the groove 5, so that the relative positions of the clamp 1, the clamping piece 4, and the tightening tube 2 are restricted, and the target tissue is stably closed. At the same time, the opening of the U-shaped structure of the clamping piece 4 is opened, so that the push-pull block 3 can be moved out of the clamping piece 4, that is, the separation of the introduction component can be achieved, which is the second state of the clamping piece 4. The advantage is that, by utilizing the elasticity and simple structure of the clamping component 4 itself, the closing of the target tissue, the locking of the relative positions of the clamp 1 and the tightening tube 2, and the separation of the push-pull block 3 and the clamp 1 can be achieved in one step (that is, the clamping component 4 can be driven to switch from the first state to the second state by pulling the push-pull block 3).

[0037] In the above embodiment, a slot structure can be constructed on the push-pull block 3 to engage with the block 6. Preferably, a pull rod shaft 7 is fixed to the proximal end of the push-pull block 3. Specifically, the push-pull block 3 is constructed as a square block, and the pull rod shaft 7 is constructed as a cylinder. The diameter of the pull rod shaft 7 is smaller than the length (or width) of the push-pull block 3, so that the opening of the U-shaped structure of the clamping member 4 can be converged to the junction of the push-pull block 3 and the pull rod shaft 7 to limit the relative position of the push-pull block 3 and the clamp 1; the pull rod shaft 7 is a part of the above-mentioned introduction component, and the push-pull block 3 can be controlled to move in the tightening tube 2 through the pull rod shaft 7. This is a prior art and will not be described in detail here.

[0038] In another embodiment provided by the present invention, further, a fastening mechanism for forcing the block 6 to be limited in the groove 5 is provided in the tightening tube 2. Specifically, when the clamping member 4 is switched to the second state, if the block 6 is the same width as the clamping groove, the block 6 cannot be accurately embedded in the groove 5 under the elastic force of the clamping member 4, so the groove 5 needs to have a certain length to allow the block 6 to be embedded. Obviously, if the length of the groove 5 is large, the block 6 has a certain range of motion in the groove 5, which may cause the position of the block 6 to move. For this reason, a fastening mechanism is provided to limit the block 6 to the far end of the groove 5; optionally, the fastening mechanism includes a fastening ring 8 elastically connected in the groove 5, and the fastening ring 8 is configured with a wedge surface. The fastening ring 8 is slidably connected in the groove 5, and the wedge surface is located between the inner wall and the top wall of the fastening ring 8. A first elastic member 9 is arranged between the fastening ring 8 and the inner wall of the tightening tube 2. The first elastic member 9 can select an elastic sheet or a spring structure in the prior art to force the fastening ring 8 to approach the far end of the groove 5; when the block 6 moves to the position of the groove 5, the block 6 can contact the wedge surface of the fastening ring 8, so as to force the fastening ring 8 to overcome the elastic force of the first elastic member 9 through the elastic force of the clamping member 4 itself, so that after the block 6 is embedded in the groove 5, the elastic force of the first elastic member 9 can continuously force the block 6 to move to the far end of the groove 5, thereby avoiding relative displacement between the clamp 1 and the tightening tube 2 as much as possible.

[0039] As an alternative or parallel solution to the above-mentioned fasteners, preferably, the fastening mechanism includes a wedge block 10 slidably connected in the tightening tube 2, and the wedge block 10 has a first position close to the proximal end and a second position close to the distal end. When the push-pull block 3 is separated from the clamping member 4, the wedge block 10 switches from the first position to the second position. Specifically, the inner wall of the tightening tube 2 is configured with a slide groove 11 along its axial direction, and the wedge block 10 is slidably connected in the slide groove 11. When the wedge block 10 is at the proximal end of the slide groove 11, it is in the first position, and when the wedge block 10 is at the distal end of the slide groove 11, it is in the second position; the wedge block 10 and the slide groove 11 are symmetrically arranged in two groups; as shown in FIG. Figure 4 As shown, the width of the corner of the V-shaped structure of the clip 1 is smaller than the inner diameter of the tightening tube 2, so that the clip 1 will not interfere with the wedge block 10 in the first position when it is moved out of or put into the tightening tube 2; when the clip 1 is put into the tightening tube 2 to close the target tissue, the block 6 is correspondingly embedded in the groove 5 (in this embodiment, the groove 5 extends to the proximal end of the tightening tube 2, and has a sufficient length for the block 6 to be embedded), and at this time, the wedge block 10 is controlled to switch from the first position to the second position ( Figure 4The middle wedge block 10 moves from bottom to top, wherein the method for controlling the movement of the wedge block 10 can be selected to be a structure similar to the pull rod shaft 7, that is, the wedge block 10 can be operated by the corresponding introduction component and the operation component, which will not be repeated here). During the process, the wedge surfaces of the two wedge blocks 10 can contact the outer walls of the two open ends of the clamp 1, so as to force the two open ends of the clamp 1 to approach each other, and then the two open ends of the clamp 1 can further clamp and close the target tissue, so as to increase the clamping force of the clamp 1 on the target tissue. The advantages are that, firstly, when the clamp 1 is received in the tightening tube 2, the clamp 1 can initially clamp and close the target tissue, and then the wedge block 10 switches from the first position to the second position to further contact the outer walls of the two open ends of the clamp 1, so as to force the two open ends of the clamp 1 to continue to approach each other to further clamp and close the target tissue, and try to avoid the clamp 1 and the tightening tube 2 from falling off from the target tissue; secondly, the wedge blocks 10 can contact the two open ends of the clamp 1 When resisting, the force applied to the clip 1 is divided into a force component toward the central axis of the tightening tube 2 and a force component toward the distal end. The force component toward the central axis of the tightening tube 2 can force the clip 1 to further clamp the target tissue, and the force component toward the distal end can force the clip 1 and the block 6 to move toward the distal end. The block 6 is embedded in the groove 5, which will further force the block 6 to be at the distal end of the groove 5, thereby limiting the relative position of the clip 1 and the tightening tube 2, and trying to stably clamp the clip 1 and the tightening tube 2 at the target tissue.

[0040] As an alternative to the above-mentioned introduction component controlling the movement of the wedge block 10, Figure 6As shown, preferably, a connecting block 12 is fixed to the far end of the tightening tube 2, and the connecting block 12 is between the two open ends of the clip 1. The connecting block 12 can prevent the V-shaped clip 1 from detaching from the tightening tube 2 as much as possible; a connecting ring 13 is arranged in the tightening tube 2, and the two wedge blocks 10 are fixed on the connecting ring 13. A second elastic member 14 is arranged between the connecting block 12 and the connecting ring 13. The second elastic member 14 can be an elastic sheet or spring structure in the prior art, so as to force the connecting ring 13 and the wedge block 10 to move toward the far end through the second elastic member 14, thereby forcing the two wedge blocks 10 to move to the far end. The block 10 is in the second position, an L-shaped rod 15 is fixed on the connecting ring 13, a contact plate 16 is provided on the inner wall of the tightening tube 2, and a contact portion 17 is constructed on the contact plate 16. A third elastic member 18 is provided between the contact plate 16 and the inner wall of the tightening tube 2. The third elastic member 18 can be an elastic sheet or a spring structure in the prior art, so that the contact portion 17 is forced to approach the push-pull block 3 through the third elastic member 18. One end of the L-shaped rod 15 is fixed on the connecting ring 13, and the other end corresponds to the contact portion 17. When the wedge block 10 stretches the second elastic member 14 to move to the first position, the L-shaped rod 1 The other end of 5 is at the bottom of the abutment 17, so that the abutment 17 can limit the positions of the L-shaped rod 15, the connecting ring 13 and the wedge block 10, and then limit the wedge block 10 to the first position; the abutment plate 16 is configured with a first wedge portion 19, and the outer wall of the push-pull block 3 is configured with a second wedge portion 20. After the push-pull block 3 drives the clip 1 to be retracted into the tightening tube 2, the clamping member 4 is separated from the push-pull block 3, and the clamping member 4 is clamped with the tightening tube 2. Then, the push-pull block 3 continues to move toward the proximal end and can be removed from the tightening tube 2. During the removal process, the second wedge portion 20 on the push-pull block 3 is used to 0 can resist the first wedge-shaped portion 19, thereby forcing the resisting plate 16 to overcome the elastic force of the third elastic member 18 and move away from the push-pull block 3. When the resisting plate 16 moves away from the push-pull block 3, the resisting portion 17 is separated from the other end of the L-shaped rod 15, so that the L-shaped rod 15 and the connecting ring 13 are free from restriction, and then the connecting ring 13, the L-shaped rod 15 and the wedge block 10 are driven to move toward the far end through the second elastic member 14, thereby forcing the wedge block 10 to move to the second position; in the above process, the L-shaped rod 15 and the clamping member 4 and other structures are staggered to avoid position interference between different structures as much as possible.The advantage is that, when the push-pull block 3 is not separated from the clamping member 4, the wedge block 10 can be limited to the first position by the contact plate 16 and other structures, and the wedge block 10 does not affect the operation of the clip 1 at this time; secondly, in the process of separation of the push-pull block 3 from the clamping member 4, the contact plate 16 and other structures can passively release the restriction of the contact plate 16 on the wedge block 10, so that the wedge block 10 can move to the second position under the action of the second elastic member 14, thereby forcing the clip 1 to further clamp the target tissue and further limit the relative position of the clamping member 4 and the tightening tube 2, so that the structures such as the fastening ring 8 in the above-mentioned embodiment can be replaced (when the fastening ring 8 structure is arranged in parallel with the present embodiment , the first elastic member 9 can be omitted and the fastening ring 8 can be fixed on the L-shaped rod 15); thirdly, when the wedge block 10 is driven to move to the second position by the second elastic member 14, the two wedge blocks 10 are subjected to the elastic force of the second elastic member 14 to resist the two open ends of the clip 1. If there are more target tissues between the clips 1, the wedge blocks 10 cannot continue to force the two open ends of the clip 1 to approach each other, so that the wedge blocks 10 cannot move to the second position after leaving the first position, but this does not affect the resistance of the wedge blocks 10 to the clip 1, so that the wedge blocks 10 can maintain the squeezing of the clip 1, so as to increase the clamping force of the clip 1 on the target tissue and maintain the relative position of the clip 1 and the tightening tube 2.

[0041] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
