Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a continuous clip applier. Background Art

[0002] In the field of medical device technology, clip applicators are often used to achieve the purpose of hemostasis, tissue fixation or isolation. However, traditional clip applicators are all single-shot structures. Although they can meet basic surgical needs, in the face of complex surgeries that require multiple hemostasis or fixation, single-shot clip applicators need to be frequently removed from the abdominal cavity, which not only reduces the operating efficiency, but also easily causes wound infection; and in the face of heavy bleeding and large-area tissue repair, single-shot clip applicators cannot quickly complete hemostasis. Therefore, in order to solve this problem, a continuous-shot clip applicator has also been developed, but it is difficult to operate, and problems such as jamming and clip falling off may occur during use, seriously affecting surgical safety.

[0003] Therefore, there is an urgent need for a continuous clip applier to solve the above-mentioned technical problems. Summary of the invention

[0047] During surgery, doctors need to be able to quickly stop bleeding in multiple locations or over a large area, and they must not insert surgical tools into the patient's abdominal cavity frequently to avoid infection. Figure 1-Figure 6 As shown, the burst clamp includes a clamp rod 10, a clamp assembly 20, a push assembly 40 and a clamp assembly 50. A movable clamp 30 is designed at one end of the clamp rod 10, and a limited space is set in the clamp rod 10. The limited space is connected to one end of the clamp rod 10 along the axial direction of the clamp rod 10 and forms an opening, and the movable clamp 30 is pivotally connected to the clamp rod 10; the clamp assembly 20 includes a plurality of V-shaped clamps 21, and the plurality of V-shaped clamps 21 are arranged in the limited space along the axial direction of the clamp rod 10 at intervals, and the plurality of V-shaped clamps 21 are in a semi-closed state (such as Figure 3 The state shown by the four V-shaped clips 21 inside the middle clamp rod 10 is a semi-closed state); the pushing component 40 is arranged on the side of the clamp rod 10 away from the limiting space, and the pushing component 40 can push the multiple V-shaped clips 21 to move in the direction of the opening, and the V-shaped clips 21 can be changed to an open state at the opening (such as Figure 2 The state shown in the V-clip 21 is an open state); the clamping assembly 50 is axially arranged in the clamp rod 10, and one end is connected to the movable clamp 30. When the clamping assembly 50 is pulled in a direction away from the clamp rod 10, the clamping assembly 50 can drive the movable clamp 30 to rotate around the pivot position, so that the V-clip 21 is switched to a closed state.

[0048] In this burst clamp, a plurality of V-shaped clips 21 are arranged in the clamp rod 10, and the pushing assembly 40 can push the plurality of V-shaped clips 21 to move toward the opening, so that the plurality of V-shaped clips 21 can pass through the opening in sequence, and after a V-shaped clip 21 passes through the opening, it can change from a semi-closed state to an open state ( Figure 3 The V-clip 21 located below the movable clamp 30 is in an open state, and the other V-clip 21 inside the clamp rod 10 is in a semi-closed state), so that the movable clamp 30 can drive the V-clip 21 to clamp; when the V-clip 21 is in an open state, it is only necessary to pull the clamp assembly 50 in a direction away from the opening, and the clamp assembly 50 can drive the movable clamp 30 to rotate around the pivot position. After the movable clamp 30 rotates, it can close the V-clip 21 together with the clamp rod 10. The closed V-clip 21 can automatically fall off from the clamp rod 10, thereby completing a clamping and fixing. Subsequently, there is no need to remove the clamp rod 10 from the abdominal cavity. Continue to use the above method to push the assembly 40 to make the remaining V-clip 21 reach the opening, and complete the clamping action through the clamp assembly 50. During this process, the clamping and fixing of multiple V-clips 21 can be completed by only pulling the clamping assembly 50 and the pushing assembly 40, which can not only achieve continuous action, but also improve the convenience of operation, reduce the difficulty of operation, and quickly achieve multiple or large-area hemostasis.

[0049] What needs to be explained here is that Figure 4 As shown, the pushing assembly 40 includes a push piece 41 and a conveying piece 42, and a convex point 421 is provided at one end of the conveying piece 42. The conveying piece 42 can be detachably connected with the push piece 41 through the convex point 421, so that the push piece 41 can be indirectly pushed by pushing the conveying piece 42, thereby completing the driving of the V-shaped clamp 21; in addition, the clamping assembly 50 includes a pull rod 51 and a clamping member 52, and the pull rod 51 is detachably connected with the clamping member 52 through a connecting pin 53, so that the clamping member 52 can be indirectly pulled by the pull rod 51, and then the movable clamp 30 is driven to rotate through the clamping member 52, thereby completing the closing of the V-shaped clamp 21. This device can not only simplify the structure, but also facilitate subsequent maintenance and replacement of parts. It is further explained that the clamping member 52 is slidably connected to both sides of the clamp rod 10, so as to ensure that when the pull rod 51 is pulled, the clamping member 52 can move more smoothly, thereby ensuring a good operating effect and improving the user experience. In addition, in order to meet actual work needs, an extension handle can be provided at the other end of the pull rod 51, so as to increase the operating space and facilitate the operation.

[0050] In addition, if Figure 4 and Figure 8As shown, the movable pliers 30 include a clamping portion 31 and a movable sheet 32, the movable sheets 32 are arranged on both sides of the clamping portion 31, and the movable sheets 32 are pivotally connected to the clamp rod 10 through the rotating shaft 33; an abutment groove 321 is arranged at the end of the movable sheet 32 ​​away from the clamping portion 31, and the clamping end of the clamping assembly 50 (the end of the clamping member 52 away from the pull rod 51) can extend into the abutment groove 321; when the clamping assembly 50 is pulled in a direction away from the opening, the clamping end (the end of the clamping member 52 away from the pull rod 51) can drive the movable sheet 32 ​​to rotate in a direction away from the clamp rod 10, and the clamping portion 31 can rotate in a direction close to the clamp rod 10, so that the clamping portion 31 can drive the V-shaped clamp 21 to close; when the clamping assembly 50 is pushed in a direction close to the opening, the clamping portion 31 can rotate and open in a direction away from the clamp rod 10, so that the V-shaped clamp 21 can be pushed to the opening. In this structure, since movable pieces 32 are provided on both sides of the clamping portion 31, when the pull rod 51 is pulled, the movable pieces 32 can be driven to rotate from both sides, and then the clamping portion 31 can be driven to rotate from both sides at the same time, so that the clamping portion 31 can have sufficient clamping force to drive the V-clip 21 to rotate and change it from an open state to a closed state, thereby completing the surgical work quickly and efficiently, ensuring the safety and reliability of the surgery, and also improving the smoothness of the operation.

[0051] To reduce the difficulty of operation, Figure 2 , Figure 6 and Figure 7 As shown, the V-shaped clamp 21 includes a first clamping member 211 and a second clamping member 212 connected to each other, and a first protrusion 213 is provided on the side of the first clamping member 211 away from the second clamping member 212; a plurality of pushing holes 411 are provided at intervals on the pushing assembly 40 (pushing sheet 41), and a plurality of first protrusions 213 can be correspondingly snapped into a plurality of first protrusions 213, so that the pushing assembly 40 can push a plurality of V-shaped clamps 21. In this structure, a plurality of pushing holes 411 are provided on the pushing sheet 41, which can cooperate with a plurality of V-shaped clamps 21 at the same time, and then can simultaneously push a plurality of V-shaped clamps 21 to move in the direction of the opening, thereby improving the operation efficiency.

[0052] Specifically, Figure 2 , Figure 6-Figure 7 As shown, the first protrusion 213 is a trapezoidal protrusion, and the side close to the opening is a first inclined surface 2131, and the side away from the opening is provided with an abutment surface 2132, and an inclined first guide surface 412 is also provided in the pushing hole 411; when the pushing component 40 is pushed toward the opening, the inner wall of the pushing hole 411 can abut against the abutment surface 2132 and push the V-clip 21, and when the pushing component 40 is pulled in a direction away from the opening, the first guide surface 412 can slide relative to the first inclined surface 2131.

[0053] In this structure, the pushing hole 411 can firstly abut against the abutting surface 2132, and the V-shaped clip 21 can be pushed by the abutting surface 2132, and when the V-shaped clip 21 needs to leave the limiting space, the first inclined surface 2131 of the V-shaped clip 21 can slide along the extension direction of the first guide surface 412, thereby making the V-shaped clip 21 detach from the pushing hole 411. After a V-shaped clip 21 is pushed out of the limiting space and clamped on the patient's blood vessel, in order to facilitate pushing the remaining V-shaped clips 21 again, the conveying sheet 42 can be pulled away from the opening first, and then the pushing sheet 41 can be indirectly pulled, and the first guide surface 412 of the pushing sheet 41 can slide relative to the first inclined surface 2131 of the remaining V-shaped clips 21, thereby preventing the V-shaped clip 21 from being pushed away from the opening, and the pushing sheet 41 can be pulled back to the original position. When the push piece 41 is returned, the remaining V-shaped clamps 21 can be pushed again by the push piece 41 to continue the clamping work, thereby avoiding the operation of repeatedly taking the clamp rod 10 out of the abdominal cavity, thereby ensuring the safety of the operation.

[0054] like Figure 2-Figure 5 As shown, a limiting groove 11 is provided on the clamp rod 10, and the limiting groove 11 is connected to one end of the opening along the axial direction, and the clamping assembly 20 is provided in the limiting groove 11; the burst clamp also includes a clamping magazine 60, which can be mutually engaged with the clamp rod 10, and the clamping magazine 60 and the inner wall of the limiting groove 11 together form a limiting space, so that multiple V-shaped clips 21 are in a semi-closed state. By providing the clamping magazine 60, multiple V-shaped clips 21 can be conveniently installed in the limiting groove 11, thereby improving the convenience of installation. In addition, the clamping magazine 60 and the clamp rod 10 can be engaged, which is convenient for the subsequent maintenance and replacement of parts, and also convenient for disassembling the clamping magazine 60 to supplement the V-shaped clips 21.

[0055] What needs to be explained here is that Figure 2-Figure 5 As shown, a plurality of snap-in grooves 12 are provided on both sides of the limit groove 11 of the clamp rod 10, and a plurality of snap-in parts 62 are provided on the clamping chamber 60. By pressing the clamping chamber 60, the snap-in parts 62 can be snap-in corresponding to the snap-in grooves 12, thereby simplifying the installation operation and reducing the difficulty of operation. In addition, in order to ensure that the clamping chamber 60 will not fall off from the clamp rod 10 during use, the continuous-fire clamp applier also includes an elastic component 90, and the elastic component 90 includes an elastic member 91 and a push seat 92, wherein one end of the elastic member 91 is connected to the clamp rod 10, and the other end is connected to the push seat 92. When the clamping chamber 60 is pressed, the elastic force of the elastic member 91 can be transmitted to the clamping chamber 60 through the push seat 92, and the snap-in part 62 of the clamping chamber 60 is firmly snapped into the snap-in groove 12, thereby further ensuring the fixing effect, avoiding the situation that the clamping chamber 60 falls off during the operation, and ensuring the safety and reliability of the operation. In addition, in this embodiment, the elastic member 91 is a spring, which has a simple structure, low price, and is easy to install and use.

[0056] In addition, if Figure 2, Figure 4 and Figure 7 As shown, the second clamping member 212 is provided with a second protrusion 214, and the side of the clip magazine 60 close to the limiting groove 11 is provided with an abutting portion 61, which can abut against the second protrusion 214. In this structure, after the clip magazine 60 is installed, the abutting portion 61 can abut against the second protrusion 214, so that the abutting portion 61 can limit the V-shaped clip 21 from the end away from the opening, avoiding the V-shaped clip 21 from moving backwards during the pushing process, thereby ensuring a good use effect and improving the fluency and safety of the surgical operation.

[0057] Specifically, Figure 6 and 7 As shown, the second protrusion 214 is a triangular protrusion, which has a second inclined surface 2141 and a third inclined surface 2142; the abutment portion 61 is provided with a second guide surface 611, and when the V-shaped clamp 21 is pushed, the second inclined surface 2141 can slide and abut against the second guide surface 611, and after passing through the abutment portion 61, the elastic force of the V-shaped clamp 21 itself can make the third inclined surface 2142 abut against the abutment portion 61 again. In this setting, when it is necessary to drive the V-shaped clamp 21 to move in the direction of the opening, the second inclined surface 2141 can slide relative to the second guide surface 611, thereby avoiding the situation where the abutment portion 61 abuts against the second protrusion 214, causing the V-shaped clamp 21 to be unable to move, and ensuring that the V-shaped clamp 21 can be smoothly pushed in the direction of the opening. After the V-shaped clamp 21 passes the abutment portion 61, the second protrusion 214 of the V-shaped clamp 21 can abut against the abutment portion 61 again. The abutment portion 61 will not hinder the V-shaped clamp 21 from moving in the direction of the opening, but can effectively prevent it from moving backward, thereby ensuring a good use effect.

[0058] To ensure that the V-clip 21 is completely opened when it reaches the opening, Figure 2-Figure 4 As shown, the first spring pieces 13 are arranged opposite to both sides of the open end of the clamp rod 10 along the width direction of the limiting groove 11. The first spring pieces 13 are recessed toward the inner side of the limiting groove 11. The first spring pieces 13 have elastic force so that the V-shaped clamp 21 can pass through the first spring pieces 13, and the first spring pieces 13 can switch the V-shaped clamp 21 from a semi-closed state to an open state. In this setting, when the V-shaped clamp 21 passes through the first spring pieces 13, the first spring pieces 13 on both sides are recessed inward, and the recessed parts can generate a certain clamping force on the second clamping member 212. At this time, the push piece 41 is continuously pushed forward, so that the first clamping member 211 and the second clamping member 212 can be opened, thereby switching to an open state.

[0059] What needs to be explained here is that Figure 3As shown, when the V-clip 21 is in an open state at the opening, the first clamping member 211 is located below the first spring sheet 13, and the second clamping member 212 is located above the first spring sheet 13. When the movable clamp 30 drives the second clamping member 212 to rotate downward, the first spring sheet 13 can be pushed outward again so that the V-clip 21 can be in a closed state. When the V-clip 21 is switched to a closed state, the whole is located below the first spring sheet 13. Since the space below the first spring sheet 13 is large, the closed V-clip 21 can no longer be limited by the open first spring sheet 13, and can therefore fall off from the opening of the clamp rod 10 by itself to complete the clamping, thereby ensuring a good use effect.

[0060] In addition, if Figure 2-Figure 4 As shown, the limiting groove 11 is also provided with a plurality of groups of second spring pieces 14 at intervals along the axial direction of the clamp rod 10, and each group of second spring pieces 14 is arranged opposite to each other along the width direction of the limiting groove 11, and the second spring pieces 14 are all recessed toward the inner side of the limiting groove 11, and the second spring pieces 14 have elastic force. When the clamping assembly 20 is pushed, the V-shaped clamp 21 can pass through the plurality of groups of second spring pieces 14 in sequence in the limiting space, and each group of second spring pieces 14 can correspondingly abut against the passing V-shaped clamp 21, so that the V-shaped clamp 21 cannot move in the reverse direction. In this structure, since the second spring sheet 14 has elastic force, when the V-shaped clamp 21 passes through a group of second spring sheets 14, the V-shaped clamp 21 can push the second spring sheets 14 outward. After the V-shaped clamp 21 passes, the second spring sheets 14 will close under the action of their own elastic force. The spacing between each group of closed second spring sheets 14 is smaller than the thickness of the V-shaped clamp 21, so that it can firmly abut the second clamping piece 212 of the V-shaped clamp 21, thereby being able to work together with the abutting portion 61 to prevent the V-shaped clamp 21 from moving backward, thereby ensuring a good use effect and improving the reliability and safety of the operation.

[0061] In addition, if Figure 1-Figure 4 as well as Fig. 9As shown, the continuous-fire clamp also includes a safety 70 and an outer tube 80. The outer tube 80 is arranged on the outer periphery of the clamp rod 10. The safety 70 can be detachably connected to the outside of the outer tube 80 for installing the clamp 60. The safety 70 includes a clamping end 71, which is located on the outer periphery of the limiting groove 11. The clamp 60 can slide to the limiting groove 11 under the clamping of the clamping end 71 to form a limiting space. In this structure, the clamp 60 can be clamped by the clamping end 71 of the safety 70 during the installation of the clamp 60, and the clamp 60 can be pressed into the limiting groove 11 under the action of external force, and in the process of moving to the limiting groove 11, it can slide relative to the side wall of the clamping end 71, ensuring the smoothness and convenience of the installation process. The outer tube 80 can be wrapped around the outer circumference of the clamp rod 10, avoiding exposure of the structure and ensuring aesthetics. At the same time, the outer tube 80 also protects the internal structure of the clamp rod 10, improves its service life, avoids scratches on the patient's body during the exposure of the structure, and ensures the safety and reliability of the operation.

[0062] In addition, if Fig. 9 As shown, the safety 70 also includes a holding end 72, which is located at the bottom end of the clamp rod 10. When installing the clamp compartment 60, the installation can be completed by holding the holding end 72, which not only improves convenience, but also improves stability and operability. In addition, the safety 70 also includes a fixing plate 73, which can be plugged into the outer periphery of the clamp rod 10, thereby further fixing the clamp rod 10 and ensuring the stability of the installation. It should be noted here that in this embodiment, the clamp rod 10 and the safety 70 are connected by a snap connection. Before use, the safety 70 is snapped onto the outer side of the outer tube 80, so as to facilitate the installation of the clamp compartment 60. After the clamp compartment 60 is installed, the safety 70 can be disassembled for use. The operation is simple and convenient, and the stability of the installation is greatly improved.

[0063] In addition, the clamp rod 10 and the clamp chamber 60 are both made of transparent materials. This arrangement can facilitate the doctor to observe the remaining number of V-shaped clamps 21 in the limited space during surgery, so that the V-shaped clamps 21 can be replenished in time after they are used up, ensuring the integrity of the surgery.

[0064] The following is a description of the use process of the burst clip applicator in this embodiment with reference to the accompanying drawings:

[0065] First, if Figure 1-Figure 3 As shown, the safety 70 is installed on the outer periphery of the outer tube 80, and a certain number of V-shaped clips 21 are placed in the limiting groove 11, and then the clamping end 71 of the safety 70 is pressed toward the limiting groove 11 to press the clip compartment 60 to turn the multiple V-shaped clips 21 into a semi-closed state. Then the safety 70 is removed;

[0066] Secondly, if Figure 3As shown, one end of the clamp rod 10 provided with the movable clamp 30 is extended into the abdominal cavity of the patient, and the conveying sheet 42 is pushed, so that the pushing sheet 41 can push the V-shaped clamp 21 to the opening. After passing through the opening, the V-shaped clamp 21 can become an open state by relying on its own elastic force and the force of the first elastic sheet 13. At this time, the pull rod 51 is pulled backward, and the clamping member 52 can drive the movable clamp 30 to rotate and switch the V-shaped clamp 21 to a closed state, thereby completing the clamping in sequence;

[0067] Finally, pull the conveying sheet 42 backward to reset the pushing sheet 41, and repeat the above operation again.

[0068] In summary, the continuous clip applier in this embodiment can not only achieve continuous clamping hemostasis, but also has low operating difficulty and smooth operation process, and can quickly achieve large-area hemostasis.
