[0054] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects clearer, the present application will be described in detail in conjunction with the drawings. The figure is a simplified schematic diagram, which only schematically illustrates the basic of the present application, and therefore only shows the structures related to the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0055] As Figure 1 shown, the present application provides a bendable and repeatedly openable and closable continuous hemostatic clip 100, which comprises an outer tube assembly 1, a pull rod assembly 2 sleeved inside the outer tube assembly 1 to accommodate a plurality of hemostatic clip assemblies 3 inside the outer tube assembly 1.

[0056] In some embodiments, as Figures 3-8As shown, the outer tube assembly 1 is substantially in the shape of a circular tube, and the outer tube assembly 1 comprises a spring tube 11, a front end piece 12 arranged at one end of the spring tube 11, and a positioning piece 13 connected between the spring tube 11 and the front end piece 12. The spring tube 11 is in the shape of a circular long tube, and the spring tube 11 is capable of being bent at a certain angle. In other embodiments, the spring tube 11 can also be processed by using other high polymer tube materials, but the material and shape of the outer tube assembly 1 are not limited thereto, and the specific limitations are not made. One end of the front end piece 12 is substantially in the shape of a circular truncated tube, and the front end piece 12 comprises a front end outer tapered surface 121 at one end, a front end inner tapered surface 122, and a front end inner boss portion 123 at the other end. The front end outer tapered surface 121 is designed in the shape of an inclined tapered surface, which can facilitate the front part of the repeatedly openable and closable continuous hemostat clip 100 to enter and exit the endoscope, thereby facilitating the insertion operation between the human tissues. The front end inner tapered surface 122 is located on the inner side surface of the front end outer tapered surface 121, and the front end inner tapered surface 122 has the same tapered surface inclination angle as the front end outer tapered surface 121, which can facilitate the hemostat clip assembly 3 to be released from the limitation of the front end piece 12 when the hemostat clip assembly 3 is taken out of the outer tube assembly 1. The positioning piece 13 is substantially in the shape of a circular tube, one end of the positioning piece 13 is connected with the front end piece 12, and the other end of the positioning piece 13 is connected with the spring tube 11. The positioning piece 13 comprises a positioning outer step portion 131 at one end, a positioning inner step portion 132, a positioning inner tapered surface 133 arranged inside the positioning piece 13, and a positioning inner interface surface 134 located away from the one end of the positioning outer step portion 131. The positioning outer step portion 131 is matched with the front end inner boss portion 123 of the front end piece 12, thereby being suitable for being tightly connected with the front end inner boss portion 123. The front end inner boss portion 123 is suitable for being matched with the hemostat clip assembly 3. The positioning inner tapered surface 133 has a smaller inner diameter at the one end close to the positioning outer step portion 131, and is suitable for placing the hemostat clip assembly 3. The positioning inner interface surface 134 is matched with the spring tube 11, thereby being suitable for being tightly connected with the spring tube 11.

[0057] In some embodiments, as shown in Figure 1 The pull rod assembly 2 comprises a rod body 21 and an end head portion 22 arranged at one end of the rod body 21. The end head portion 22 is provided with a first connecting hole, and the end head portion of the pull rod assembly 2 is sleeved in the hemostat clip assembly 3 at the end of the outer tube assembly 1 and connected with the hemostat clip assembly 3 at the end of the outer tube assembly 1.

[0058] In some embodiments, as shown in Figures 9-14 The hemostat clip assembly 3 comprises a fixed seat 32, a fixed pad 33, a connecting piece 34, and two hemostat clip subassemblies 31 connected with the connecting piece 34. In addition, it should be noted that the hemostat clip assembly 3 at the end of the outer tube assembly 1 does not comprise the connecting piece 34, and the hemostat clip assembly 3 at the end of the outer tube assembly 1 is connected with the pull rod assembly 2 through the connecting pin 345.

[0059] In some embodiments, as shown in Figures 15-17As shown, the hemostatic clip 31 is integrally formed by an elastic material. The two hemostatic clips 31 are symmetrical in structure, and each of the hemostatic clip 31 comprises a clamping piece 311, a connecting portion 312, a transition portion 313, and a clamping edge 314 provided at an end of the clamping piece 311 away from the transition portion 313. The two ends of the transition portion 313 are respectively connected with the connecting portion 312 and the clamping piece 311. The connecting portion 312 is provided with a clamping hole 3121 and a clamping spring 3122, and the clamping spring 3122 is located at a side close to the transition portion 313. The width of the clamping piece 311 is greater than the width of the transition portion 313, and the transition portion 313 is substantially arc-shaped. A clamping piece hole 3111 is further formed in the clamping piece 311, and the clamping piece hole 3111 is adapted to be connected with the connecting piece 34. The end of the clamping piece 311 away from the transition portion 313 is provided with the clamping edge 314, and the middle part of the clamping edge 314 is provided with a semicircular arc-shaped recess 3141. The clamping edge 314 is further provided with a clamping tooth 3142, and the clamping teeth 3142 on the two hemostatic clips 31 in the same hemostatic clip assembly 30 are engaged with each other. The hemostatic clip 31 provided in the embodiment has a simple processing technology and is easier to form.

[0060] In some embodiments, as Figures 18-21As shown, the fixing seat 32 is substantially cylindrical, and the cylindrical fixing seat 32 is adapted to be assembled with the hemostatic clip 31, the connecting piece 34 and the fixing pad 33. The fixing seat 32 comprises an outer taper portion 321 arranged at one end, fixing seat grooves 322 symmetrically arranged at two sides of the outer taper portion 321, clamping protrusions 323 arranged at one end away from the outer taper portion 321, an inner protrusion step portion 324 arranged in the outer taper portion 321, and clamping grooves 325 symmetrically arranged on the outer side surface of the fixing seat 32. The outer taper portion 321 is located at one end of the fixing seat 32, and the outer taper portion 321 comprises an outer taper surface 3211 and an inner taper surface 3212 arranged at one end close to the clamping protrusion 323. The diameter of the outer taper surface 3211 is greater than the diameter of other parts of the fixing seat 32, and the outer taper surface 3211 is in an outwardly flared state. The fixing seat grooves 322 are arranged in two, and are symmetrically arranged at two sides of the outer taper portion 321. When the fixing seat 32 passes through the positioning piece 13, the outer taper surface 3211 of the outer taper portion 321 is in contact with the positioning inner taper surface 133 of the positioning piece 13. Under the action of external force, when the fixing seat 32 continues to move to the front end, the fixing seat grooves 322 arranged thereon can make the outer taper portion 321 shrink inwardly, so as to smoothly pass through the inside of the positioning piece 13, until the fixing seat 32 completely separates from the inside of the positioning piece 13 and reaches the inside of the front end piece 12. At this time, the rear end of the fixing seat 32 is clamped at the positioning inner step portion 132 of the positioning piece 13. The outer taper surface 3211 of the outer taper portion 321 cooperates with the front end inner taper surface 122 of the front end piece 12. The clamping protrusions 323 are arranged in two, and are symmetrically arranged at one end away from the outer taper portion 321 of the fixing seat 32. The clamping protrusions 323 are adapted to cooperate with the fixing pad 33. When the hemostatic clip 31 needs to be in a hemostasis state, the clamping elastic piece 3122 on the hemostatic clip 31 is clamped at the inner protrusion step portion 324 when the hemostatic clip 31 is subjected to a larger pulling force of the connecting piece 34. At this time, the hemostatic clip 31 is in a locked state. The inclination angle of the inner taper surface 3212 of the outer taper portion 321 is the same as that of the clamping elastic piece 3122 on the hemostatic clip 31, so as to facilitate the transition of the clamping elastic piece 3122 from the inner taper surface 3212 of the outer taper portion 321 to the inner protrusion step portion 324. The clamping grooves 325 are symmetrically arranged in two, and are connected with the outer taper portion 321. When the hemostatic clip 31 is repeatedly opened and closed, the clamping elastic piece 3122 on the hemostatic clip 31 moves in the clamping grooves 325.

[0061] In some embodiments, as Figures 22-23As shown, the fixing pad 33 is installed at the end of the fixing seat 32 away from the outer cone part 321, and the fixing pad 33 comprises a first clamping groove 331 and a second clamping groove 332 which are arranged at the edge of the fixing pad 33. The second clamping groove 332 is symmetrically arranged with two, and is matched with the clamping convex 323 on the fixing seat 32. The first clamping groove 331 is symmetrically arranged with two, and the width of the first clamping groove 331 is smaller than the width of the clamping piece 311 in the hemostat clip 31. When the hemostat clip 31 reaches the fixing pad 33, the front end surface of the fixing pad 33 is clamped at the rear end of the clamping piece 311 due to the wider width of the clamping piece 311.

[0062] In some embodiments, as shown in the drawings, Figures 24-25 As shown, the connecting piece 34 comprises a connecting rod 341, a connecting end 342 arranged at one end of the connecting rod 341, a second connecting hole 343 arranged on the connecting end 342, a connecting piece 344 arranged at the other end of the connecting rod 341, and a connecting pin 345. The connecting piece 34 is connected with the hemostat clip 31 at the front end and the hemostat clip 31 at the rear end, respectively. Only the connecting pin 345 needs to be arranged to pass through the first connecting hole on the end head part 22 of the pull rod assembly 2 and the clamping hole 3121 on the hemostat clip 31 in the last hemostat clip assembly 3 in the outer tube assembly 1, so as to realize the installation of the last hemostat clip assembly 3. The second connecting hole 343 is matched with the connecting pin 345, and the first connecting hole and the second connecting hole 343 are the same in shape. The first connecting hole and the second connecting hole 343 can be circular or other shapes, and the shape of the second connecting hole 343 is not limited, and is not limited in particular. The cross section of the connecting pin 345 is matched with the shape of the second connecting hole 343. During installation, the connecting pin 345 passes through the clamping hole 3121 on the hemostat clip 31 at the front end and the second connecting hole 343, respectively, so as to realize the connection of the connecting piece 34 with the hemostat clip 31 at the front end. The connecting piece 344 arranged at the other end of the connecting rod 341 passes through the clamping piece hole 3111 on the hemostat clip 31 to be fixedly connected, so as to realize the connection of the connecting piece 34 with the hemostat clip 31 at the rear end, and thus the multiple hemostat clip assemblies 3 are sequentially fixedly connected by using the connecting piece 34. Since the pull rod assembly 2 is connected with the hemostat clip assembly 3 at the rear end, when the pull rod assembly 2 is pulled, all the hemostat clip assemblies 3 can be moved in the outer tube assembly 1.

[0063] In some embodiments, as shown in the drawings, Figure 2 As shown, the repeatedly openable and closable hemostat clip 100 in the application further comprises a handle assembly 4, and the hemostat clip assembly 33 can be released by operating the handle assembly 4. The handle assembly 4 comprises a first handle 41 and a second handle 42, the first handle 41 is fixedly connected with the outer tube assembly 1, and the second handle 42 is fixedly connected with the pull rod assembly 2. During use, the first handle 41 is held still, and the second handle 42 is moved when the pull rod 20 needs to be pushed or pulled for operation, so that the use is convenient.

[0064] The process of using the bendable and repeatedly openable and closed continuous hemostatic clip 100 of the present invention is as follows: Figures 26-28 As shown, first extend the continuous hemostatic clamp of the present invention into the mucosal tissue or blood vessels in the human body that need to stop bleeding. At this time, the continuous hemostatic clamp is in a loaded state. At this time, the rear end of the fixing seat 32 is engaged with the positioning inner step portion 132 connected to the positioning member 13. At this time, the pull rod assembly 2 is pulled backward, and the fixing seat 32 is restricted from being pulled backward. The outer cone surface 3211 of the outer cone 321 contacts the front end inner cone surface 122 of the front end member 12, and the fixing seat 32 is restricted from being pushed forward. At this time, the hemostatic clamp assembly 3 at the front end is driven by the pull rod assembly 2. The hemostatic clamp 31 Driven by the connecting piece 34, the hemostatic clip 31 moves back and forth in the fixing seat 32, thereby realizing the repeated opening and closing of the hemostatic clip 31, that is, when the pull rod assembly 2 is pulled, the connecting piece 34 in the hemostatic clip assembly 3 at the front end is driven to move backward. Since the hemostatic clip 31 is connected to the connecting piece 34 through the connecting pin 345, the backward movement of the connecting piece 34 will drive the hemostatic clip 31 to move backward, pushing the pull rod assembly 2 forward, and the connecting piece 34 pushes the hemostatic clip 31 to move forward. The engaging spring piece 3122 on the hemostatic clip 31 moves forward in the slot 325 on the fixing seat 32. After the two hemostatic clips 31 clamp the tissue wound or blood vessel, the pull rod assembly 2 is pulled backward with a large pulling force, and the connecting piece 34 drives the hemostatic clip 31 to move backward. At this time, the engaging spring piece 3122 on the hemostatic clip enters the inner cone surface 3212 of the outer cone 321 and moves backward until the engaging spring piece 3122 is engaged with the inner convex step portion 324. The hemostatic clip assembly 3 is in a locked state. At this time, if the pull rod assembly 2 is pushed forward again, the hemostatic clip 31 will no longer open. The pull rod assembly 2 is then pushed forward, and the hemostatic clip assembly 3 moves forward. At this time, the outer conical surface 3211 of the fixing seat 32 contacts the front inner conical surface 122 of the front end member 12, and continues to move forward under the action of the force. The fixing seat groove 322 is provided to enable the outer conical portion 321 to retract inward, and the rear end of the fixing seat 32 retracts inward until the rear end of the fixing seat 32 is completely free from the restriction of the positioning member 13. The pull rod assembly 2 is then pushed forward, and the hemostatic clip assembly 3 at the rear end moves forward. The hemostatic clip 31 extends out of the front end member 12. Without the constraint of the inner wall of the front end member 12, the hemostatic clip 31 spreads outward under the action of its own elasticity, and the front end hemostatic clip assembly 3 is now completely free. During use of the present invention, when the hemostatic clip 31 is not in the ideal clamping position for the tissue wound or blood vessel, the hemostatic clip 31 can be adjusted to the ideal clamping position by opening and closing the hemostatic clip 31, thereby ensuring the hemostatic effect.
