Description

Technical Field

[0001] The present disclosure relates to the technical field of rapid-fire clip appliers, and in particular to a clip applier structure and a rapid-fire clip applier. Background Art

[0002] Clip appliers, as key tools used for ligating blood vessels or tubular structures in human surgery, play a vital role in the medical field.

[0003] However, the design of clip applicators under the current technical background, such as patent document CN219480229U, generally has some shortcomings. Most mainstream clip applicators on the market use a clamping head to abut against the clamp in the jaws to keep the clamp in the jaws stable during the clamping process, but the above design not only increases the manufacturing complexity of the clip applicator, but also significantly increases its production cost. More importantly, the abutment support thickness of the clamping head and the clamping head of the current commercially available clip applicators is generally around 0.2 mm, which is difficult to provide sufficient support for the clamp in the jaws. Therefore, in actual use, the clamp in the jaws often lacks stability, so that the clamp in the jaws will shake during use of the clip applier, which can easily lead to inaccurate clamping position or even falling of the clamp, which not only affects the accuracy and efficiency of the operation, but is also likely to cause medical accidents, greatly reducing the safety and stability of the use of the clip applier; at the same time, due to the thin thickness of the clamp delivery head, the clamp delivery head is easily damaged or even damaged and falls off during use of the clip applier, which not only further reduces the stability of the use of the clip applier, but also greatly reduces the service life of the clip applier.

[0037] A clamping structure is used to be installed on a continuous-fire clamp applier, the clamping structure includes a conveying component and a clamping claw component; the clamping claw component is arranged at the discharge end of the conveying component, the conveying component forms a feeding trough, the feeding trough accommodates a clamping member, the clamping claw component forms a clamping area, the feeding trough is connected to the clamping area, the conveying component is used to push the clamping member into the clamping area, and the conveying component is also used to support the clamping member in the feeding trough to stop retreat, the clamping member located at the discharge end of the conveying component abuts against the clamping member located in the clamping area, so that the clamping member located at the discharge end of the conveying component is supported by the clamping member located in the clamping area.

[0038] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0039] like Figures 1 to 10 As shown, a continuous-fire clip applier 20 of an embodiment is used to be installed on the continuous-fire clip applier 20, and the clip structure 10 includes a conveying assembly 100 and a clamping jaw assembly 200; the clamping jaw assembly 200 is arranged at the discharge end of the conveying assembly 100, the conveying assembly 100 is formed with a feeding trough 110, and the feeding trough 110 is used to accommodate the clamping member 30, and the clamping jaw assembly 200 is formed with a clamping area 210, and the clamping area 210 is used to accommodate the clamping member 30, and the clamping jaw assembly 200 is used to clamp the clamping member 30 located in the clamping area 210, and the feeding trough The conveying assembly 100 is used to push the clamping member 30 into the clamping zone 210, so that the conveying assembly 100 can push the clamping member 30 in the feeding trough 110 into the clamping zone 210, so that during the operation, the surgeon can clamp the clamping member 30 in the clamping zone 210 on the blood vessel or tubular structure of the human body through the clamping structure 10 to ligate the blood vessel or tubular structure to stop bleeding; and the conveying assembly 100 is also used to support the clamping member 30 in the feeding trough 110 to stop retreating. The clamping member 30 at the discharge end of the conveying assembly 100 abuts against the clamping member 30 in the clamping area 210, so that the clamping member 30 at the discharge end of the conveying assembly 100 is supported on the clamping member 30 in the clamping area 210. Compared with the design of the clamp applicator of the above-mentioned related art that abuts against the clamp by the clamping head, the clamping structure 10 of the present invention is directly supported by the clamping member 30 at the discharge end of the conveying assembly 100 against the clamping member 30 in the clamping area 210, which greatly improves the clamping structure 10 at the clamping area 210. The support thickness L of the clamping member 30 in the clamping area 210 effectively solves the problem of the clamping member 30 in the clamping area 210 shaking during the clamping operation, so that the support stability of the clamping structure 10 of the present invention during the clamping operation is greatly improved, and the clamping structure 10 is avoided from being misaligned or falling from the clamping area 210 due to the shaking of the clamping member 30 located in the clamping area 210 during use, thereby greatly improving the safety and stability of the use of the continuous clip applier 20.

[0040] like Figures 1 to 10 As shown, further, compared with the design of the clip applier of the above-mentioned related technology that uses a clip feeding head to support the clip in the jaws, the clip applier structure 10 of the present invention can support the clamping member 30 in the clamping area 210 without designing and manufacturing a clip feeding head, which not only greatly reduces the processing and manufacturing difficulty and production cost of the continuous clip applier 20 of the present invention, but also avoids the situation where the use stability and service life of the continuous clip applier 20 are reduced due to damage or even damage and falling of the clip feeding head, further improves the use stability of the continuous clip applier 20, and at the same time greatly extends the service life of the continuous clip applier 20.

[0041] In the present embodiment, during the use of the clamping structure 10, first, the conveying component 100 pushes the clamping piece 30 in the feeding trough 110 into the clamping area 210, and the clamping piece 30 located at the discharge end of the conveying component 100 abuts against the clamping piece 30 located in the clamping area 210 under the support of the conveying component 100. At the same time, the conveying component 100 can support the clamping piece 30 located at the discharge end of the conveying component 100, so that when the surgeon uses the clamping structure 10 to ligate and stop bleeding on human blood vessels or control structures, the clamping piece 30 in the clamping area 210 can maintain stability, avoiding the clamping structure 10 from shaking, resulting in the clamping piece 30 being misaligned or falling from the clamping area 210, thereby improving the operating accuracy and operating stability of the clamping structure 10, thereby greatly improving the use stability and safety of the clamping structure 10.

[0042] Since the clamping jaw assembly 200 is arranged at the discharge end of the conveying assembly 100, the conveying assembly 100 is formed with a feeding trough 110, and the feeding trough 110 is used to accommodate the clamping member 30, the clamping jaw assembly 200 is formed with a clamping area 210, and the clamping area 210 is used to accommodate the clamping member 30, the clamping jaw assembly 200 is used to clamp the clamping member 30 located in the clamping area 210, the feeding trough 110 is communicated with the clamping area 210, and the conveying assembly 100 is used to push the clamping member 30 into the clamping area 210. , so that the conveying assembly 100 can push the clamping member 30 in the feeding trough 110 into the clamping area 210, so that during the operation, the surgeon can clamp the clamping member 30 in the clamping area 210 on the blood vessel or tubular structure of the human body through the clamping structure 10 to ligate and stop bleeding of the blood vessel or tubular structure; and the conveying assembly 100 is also used to support and stop the clamping member 30 in the feeding trough 110, and the clamping member 30 at the discharge end of the conveying assembly 100 and the clamping member 30 at the clamping area 210 are supported and stopped. The clamping member 30 in the clamping area 210 is abutted so that the clamping member 30 located at the discharge end of the conveying component 100 is supported on the clamping member 30 located in the clamping area 210. Compared with the design of the clamp applicator of the above-mentioned related technology that supports the clamp by abutting the clamp with the feeding clamp head, the clamping structure 10 of the present invention is directly supported by the clamping member 30 located at the discharge end of the conveying component 100 against the clamping member 30 located in the clamping area 210, which greatly improves the support thickness L of the clamping member 30 located in the clamping area 210, and effectively solves the problem of shaking of the clamping member 30 in the clamping area 210 during the clamping operation, so that the supporting stability of the clamping structure 10 of the present invention during the clamping operation is greatly improved, and the clamping structure 10 is avoided. The phenomenon of clamping dislocation or the clamping member 30 falling from the clamping area 210 due to the shaking of the clamping member 30 in the clamping area 210 during use, thereby greatly improving the safety and stability of the continuous clip applier 20.

[0043] Compared with the design of the clip applier of the above-mentioned related technology that uses a clip feeding head to support the clip in the jaws, the clip applying structure 10 disclosed in the present invention can support the clamping member 30 in the clamping area 210 without designing and manufacturing a clip feeding head, which not only greatly reduces the processing and manufacturing difficulty and production cost of the continuous clip applier 20 disclosed in the present invention, but also avoids the situation where the use stability and service life of the continuous clip applier 20 are reduced due to damage or even damage and falling of the clip feeding head, further improves the use stability of the continuous clip applier 20, and at the same time greatly extends the service life of the continuous clip applier 20.

[0044] It can be understood that when the clamp applicator of the above-mentioned related technology abuts the clamp in the supporting jaws through the clamp feeding head, the supporting force applied by the clamp feeding head to the clamp in the jaws is a horizontal force, while the clamping structure 10 disclosed in the present invention abuts the clamping member 30 in the supporting clamping area 210 through the clamping member 30 at the discharge end of the conveying component 100, so that the direction Y of the limiting supporting force applied by the clamping member 30 at the discharge end of the conveying component 100 to the clamping member 30 in the clamping area 210 is biased toward the first clamping jaw member 220, so that when the clamping jaw assembly 200 squeezes the clamping member 30 in the clamping area 210, the clamping member 30 cannot be securely limited in the clamping area 210, resulting in the clamping jaw assembly 200 being prone to shaking or even falling from the clamping area 210 when squeezing the clamping member 30, which greatly reduces the safety and stability of the clamping structure 10.

[0045] like Figures 2 to 6 As shown, in one embodiment, the clamping jaw assembly 200 includes a first clamping jaw member 220 and a second clamping jaw member 230, the clamping portion of the first clamping jaw member 220 and the clamping portion of the second clamping jaw member 230 together form a clamping area 210, the clamping portion of the first clamping jaw member 220 is located on one side of the clamping area 210 and is formed with a first limiting groove 221 connected to the clamping area 210, the clamping portion of the second clamping jaw member 230 is located on one side of the clamping area 210 and is formed with a second limiting groove 231 connected to the clamping area 210, there is a first preset angle a between the clamping portion of the first clamping jaw member 220 and the connecting portion of the first clamping jaw member 220, and there is a second preset angle a between the clamping portion of the second clamping jaw and the connecting portion of the second clamping jaw b, the angle of the first preset angle a is smaller than the angle of the second preset angle b, so that when the clamping member 30 located at the discharge end of the conveying component 100 applies a supporting force to the clamping member 30 in the clamping area 210, the clamping end of the clamping member 30 located in the clamping area 210 can be securely limited in the first limiting groove 221 and the second limiting groove 231, so that the clamping member 30 can be securely limited in the clamping area 210 to avoid the clamping member 30 shaking or even detaching from the clamping area 210 during the squeezing process of the clamping jaw assembly 200, which greatly improves the operating accuracy and stability of the clamping structure 10, and further improves the use stability and safety of the continuous clamp 20.

[0046] like Figures 2 to 4As shown, in one embodiment, the clamping jaw assembly 200 also includes an elastic member (not shown), the connecting portion of the first clamping jaw member 220 is rotatably connected to the conveying assembly 100, and the connecting portion of the second clamping jaw member 230 is rotatably connected, and the elastic member is respectively connected to the first clamping jaw member 220 and the second clamping jaw member 230, so that a preset clamping angle d is opened between one end of the connecting portion of the first clamping jaw member 220 adjacent to the clamping area 210 and one end of the connecting portion of the second clamping jaw member 230 adjacent to the clamping area 210, so that the clamping member 30 in the conveying assembly 100 can smoothly enter the clamping area 210 under the push of the conveying assembly 100.

[0047] It can be understood that when the preset angle is too large, the clamping jaw assembly 200 cannot securely limit the clamping member 30 in the clamping area 210, so that when the clamping jaw assembly 200 squeezes the clamping member 30 in the clamping area 210, the clamping member 30 will shake or even escape from the clamping area 210, thereby greatly reducing the stability and safety of the clamping structure 10. When the preset angle is too small, the conveying assembly 100 cannot smoothly convey the clamping member 30 in the feeding trough 110 to the clamping area 210, thereby greatly reducing the stability of the clamping structure 10.

[0048] like Figure 4 As shown, in one embodiment, the preset clamping angle d is in the range of 17°-24°, so as to avoid the phenomenon that the clamping member 30 cannot be securely confined in the clamping area 210 due to the preset angle being too large, and at the same time avoid the phenomenon that the conveying component 100 cannot be pushed into the clamping area 210 due to the preset angle being too small, so that the conveying component 100 can smoothly convey the clamping member 30 in the feeding trough 110 to the clamping area 210, and the clamping jaw assembly 200 can also securely confine the clamping member 30 in the clamping area 210, so as to avoid the clamping member 30 shaking when the clamping jaw assembly 200 squeezes the clamping member 30 in the clamping area 210, thereby greatly improving the stability of the clamping structure 10.

[0049] like Figure 2 and Figure 6 As shown, in one embodiment, the first clamping jaw 220 is also formed with a first guide groove 222 connected to the clamping area 210, and the first guide groove 222 is formed between the first limiting groove 221 and the conveying component 100, so that when the conveying component 100 pushes the clamping member 30 in the feeding trough 110 into the clamping area 210, the clamping end of the clamping member 30 will easily enter the first limiting groove 221 along the guiding direction of the first guide groove 222 and be limited in the first limiting groove 221, so as to ensure that the conveying component 100 can convey the clamping member 30 to the preset position of the clamping area 210 through the first guide groove 222, so that the clamping structure 10 can stably "unclamp", further improving the stability of the clamping structure 10 in use.

[0050] like Figure 2 and Figure 6 As shown, in one embodiment, the second clamping jaw 230 is also formed with a second guide groove 232 connected to the clamping area 210, and the second guide groove 232 is formed between the second limiting groove 231 and the conveying component 100, so that when the conveying component 100 pushes the clamping member 30 in the feeding trough 110 into the clamping area 210, the clamping end of the clamping member 30 will easily enter the second limiting groove 231 along the guiding direction of the second guide groove 232 and be limited in the second limiting groove 231, so that the conveying component 100 can ensure that the clamping member 30 is transported to the preset position of the clamping area 210 through the mutual cooperation of the first guide groove 222 and the second guide groove 232, so that the clamping structure 10 can stably "clamp out", further improving the stability of the clamping structure 10 in use.

[0051] like Figure 2 and Figure 6 As shown, in one embodiment, the first clamping jaw member 220 includes a first clamping portion 223 and a first connecting portion 224, the first limiting groove 221 and the first guiding groove 222 are both provided on the first clamping portion 223, the first clamping portion 223 is fixedly connected to the first connecting portion 224, the first connecting portion 224 is rotatably connected to the conveying assembly 100, and the angle formed between the length direction of the first clamping portion 223 and the length direction of the first connecting portion 224 is a first preset angle a, so that when the first clamping jaw member 220 is located in the conveying assembly 100, the first clamping jaw member 220 is fixedly connected to the first connecting portion 224, and the first connecting portion 224 is rotatably connected to the conveying assembly 100. When the clamping member 30 at the discharge end of the member 100 applies a supporting force to the clamping member 30 in the clamping area 210, the clamping end of the clamping member 30 in the clamping area 210 can be securely limited in the first limiting groove 221, so that the clamping member 30 can be securely limited in the clamping area 210, so as to avoid the clamping member 30 shaking or even leaving the clamping area 210 during the process of the clamping jaw assembly 200 squeezing the clamping member 30, thereby greatly improving the operation accuracy and stability of the clamping structure 10. Furthermore, the first clamping portion 223 and the first connecting portion 224 are an integrally formed structure to improve the overall structural compactness of the first clamping jaw 220.

[0052] like Figure 2 and Figure 6As shown, in one embodiment, the second clamping jaw member 230 includes a second clamping portion 233 and a second connecting portion 234, the second limiting groove 231 and the second guiding groove 232 are both provided on the second clamping portion 233, the second clamping portion 233 is fixedly connected to the second connecting portion 234, the second connecting portion 234 is rotatably connected to the conveying assembly 100, and the angle formed between the length direction of the second clamping portion 233 and the length direction of the second connecting portion 234 is a second preset angle b, so that when the conveying assembly is located When the clamping member 30 at the discharge end of the clamping structure 100 applies a supporting force to the clamping member 30 in the clamping area 210, the clamping end of the clamping member 30 in the clamping area 210 can be securely limited in the second limiting groove 231, so that the clamping member 30 can be securely limited in the clamping area 210, so as to avoid the clamping member 30 shaking or even escaping from the clamping area 210 during the process of the clamping jaw assembly 200 squeezing the clamping member 30, further improving the operation accuracy and stability of the clamping structure 10. Furthermore, the second clamping portion 233 and the second connecting portion 234 are an integrally formed structure to improve the overall structural compactness of the second clamping jaw 230.

[0053] like Figure 2 and Figure 4 As shown, in one embodiment, the first clamping portion 223 is inclined relative to the first connecting portion 224 toward the preset direction X, and the second clamping portion 233 is inclined relative to the second connecting portion 234 toward the preset direction X, so that the clamping member 30 can be securely confined in the clamping area 210.

[0054] like Figure 2 and Figure 4 As shown, in one embodiment, the first connecting portion 224 forms a first avoidance area (not shown), and the first avoidance area is arranged relative to the conveying component 100 to avoid the first connecting portion 224 being blocked by the conveying component 100 when the first connecting portion 224 rotates toward the second connecting portion 234, resulting in the first clamping portion 223 being unable to rotate to the preset position, thereby enabling the first clamping portion 223 to abut against the second clamping portion 233 to jointly squeeze the clamping member 30 in the clamping area 210.

[0055] like Figure 2 and Figure 4 As shown, in one embodiment, the second connecting portion 234 is formed with a second avoidance area (not shown), and the second avoidance area is arranged relative to the conveying component 100 to avoid the second connecting portion 234 being blocked by the conveying component 100 when the second connecting portion 234 rotates in the direction close to the first connecting portion 224, resulting in the second clamping portion 233 being unable to rotate to the preset position, thereby enabling the second clamping portion 233 to abut against the first clamping portion 223 to jointly squeeze the clamping member 30 in the clamping area 210.

[0056] like Figure 2and Figure 4 As shown, in one embodiment, the first end of the first connecting portion 224 is fixedly connected to the first clamping portion 223, the connecting portion between the first end of the first connecting portion 224 and the second end of the first connecting portion 224 is rotatably connected to the conveying component 100, the second end of the second connecting portion 234 is fixedly connected to the second clamping portion 233, the connecting portion between the second end of the second connecting portion 234 and the second end of the second connecting portion 234 is rotatably connected to the conveying component 100, the first end of the elastic member is elastically pressed on the second end of the first connecting portion 224, and the second end of the elastic member is elastically pressed on the second connecting portion 234, so that the second end of the first connecting portion 224 and the second end of the second connecting portion 234 are close to each other, so that the first clamping portion 223 and the second clamping portion 233 are separated from each other, and then the clamping jaw assembly 200 is opened to the preset clamping angle d, so that the conveying component 100 can smoothly convey the clamping member 30 in the feeding trough 110 to the clamping area 210.

[0057] like Figure 2 and Figure 4 As shown, in one embodiment, there is a preset difference between the first preset angle a and the second preset angle b, so that when the clamping member 30 located at the discharge end of the conveying component 100 applies a supporting force to the clamping member 30 in the clamping area 210, the clamping end of the clamping member 30 located in the clamping area 210 can be securely limited in the first limiting groove 221 and the second limiting groove 231, so that the clamping member 30 can be securely limited in the clamping area 210, so as to avoid the clamping member 30 shaking or even detaching from the clamping area 210 during the squeezing process of the clamping jaw assembly 200, thereby greatly improving the operating accuracy and stability of the clamping structure 10.

[0058] It can be understood that when the preset difference is too large, the clamping member 30 cannot be securely confined in the clamping member 30 within the clamping member 200, so that when the clamping member 30 in the clamping area 210 is squeezed by the clamping member 30 of the clamping member 200, the clamping member 30 will shake and fall off the clamping area 210, which greatly reduces the stability of the clamping structure 10. When the preset difference is too small, the conveying member 100 cannot smoothly convey the clamping member 30 in the feeding trough 110 to the clamping area 210, so that the clamping structure 10 cannot be smoothly "unclamped", which greatly reduces the stability of the clamping structure 10.

[0059] like Figure 2 and Figure 4As shown, in one embodiment, the preset difference range is 8°-12°, so as to avoid the phenomenon that the clamping member 30 shakes and falls off the clamping area 210 when the clamping jaw assembly 200 squeezes the clamping member 30 in the clamping area 210 due to the preset difference being too large, and at the same time, avoid the phenomenon that the conveying assembly 100 is unable to effectively convey the clamping member 30 in the feeding trough 110 to the clamping area 210 due to the preset difference being too small, thereby greatly improving the stability of the clamping structure 10.

[0060] like Figure 4 and Figure 6 As shown, in one embodiment, the preset difference is 10°, so that when the clamping member 30 at the discharge end of the conveying component 100 abuts against the clamping member 30 in the supporting clamping area 210, the clamping member 30 in the clamping area 210 can be more securely confined in the clamping area 210, which can avoid the clamping member 30 shaking and falling off the clamping area 210 when the clamping jaw assembly 200 squeezes the clamping member 30 in the clamping area 210 due to the preset difference being too large, and at the same time, it can also avoid the conveying component 100 being unable to effectively convey the clamping member 30 in the feeding trough 110 to the clamping area 210 smoothly due to the preset difference being too small, thereby greatly improving the stability of the clamping structure 10.

[0061] like Figure 4 and Figure 6 As shown, in one embodiment, the angle range of the first preset angle a is 0°-25°, so that when the clamping member 30 at the discharge end in the conveying component 100 abuts against the clamping member 30 in the supporting clamping area 210, the clamping end of the clamping member 30 in the clamping area 210 can be securely limited in the first limiting groove 221, thereby improving the stability of the clamping structure 10.

[0062] like Figure 4 and Figure 6 As shown, in one embodiment, the angle of the first preset angle a is 7.5°, so that when the clamping member 30 at the discharge end in the conveying component 100 abuts against the clamping member 30 in the supporting clamping area 210, the clamping end of the clamping member 30 in the clamping area 210 can be more securely limited in the first limiting groove 221, so as to improve the stability of the clamping structure 10 in use.

[0063] like Figure 4 and Figure 6 As shown, in one embodiment, the range of the second preset angle is 10°-35°, so that when the clamping member 30 at the discharge end in the conveying component 100 abuts against the clamping member 30 in the supporting clamping area 210, the clamping end of the clamping member 30 in the clamping area 210 can be securely limited in the second limiting groove 231, further improving the stability of the clamping structure 10.

[0064] like Figure 4 and Figure 6 As shown, in one embodiment, the angle of the second preset angle b is 17.5°, so that when the clamping member 30 at the discharge end in the conveying component 100 abuts against the clamping member 30 in the supporting clamping area 210, the clamping end of the clamping member 30 in the clamping area 210 can be more securely limited in the second limiting groove 231, so as to improve the stability of the clamping structure 10 in use.

[0065] like Figure 6 and Fig. 9 As shown, in one embodiment, the discharge end of the conveying component 100 is also formed with an abutment limit flange 130, and the abutment limit flange 130 abuts and supports the clamping member 30 located in the clamping area 210, so that the clamping member 30 located in the clamping area 210 can be securely limited in the clamping area 210 through the mutual cooperation between the clamping member 30 located at the discharge end of the conveying component 100 and the abutment limit flange 130, so that the stability of the clamping structure 10 is greatly improved; at the same time, when the conveying component 100 conveys the clamping member 30 to the clamping area 210, the abutment limit flange 130 can also play a guiding and limiting role.

[0066] like Figure 6 and Fig. 9 As shown, in one embodiment, an abutment limiting flange 130 is formed at one end of the conveying assembly 100 adjacent to the first clamping jaw member 220 , so that the clamping member 30 can be more securely limited in the clamping area 210 .

[0067] like Figure 6 and Fig. 9 As shown, in one embodiment, the abutment limit flange 130 is an arc-shaped structure, which not only enables the abutment limit flange 130 to securely limit the clamping member 30 in the clamping area 210, but also can buffer the supporting force applied by the clamping member 30 at the discharge end of the conveying component 100 to the clamping member 30 located in the clamping area 210, thereby avoiding the clamping member 30 from being damaged or even destroyed due to excessive supporting force, thereby greatly improving the stability of the clamping structure 10.

[0068] It can be understood that when the support thickness L of the abutting end of the clamping member 30 is too large, the volume of the clamping member 30 will be greatly increased, so that the clamping structure 10 requires a larger space area to accommodate the clamping member 30, which greatly increases the volume and weight of the clamping structure 10, thereby greatly reducing the portability of the clamping structure 10; when the support thickness L of the abutting end of the clamping member 30 is too small, the clamping member 30 located at the discharge end of the conveying component 100 cannot effectively support the clamping member 30 in the clamping area 210, so that the clamping member 30 located in the clamping area 210 is prone to shaking or even falling off from the clamping area 210 during the clamping operation, thereby greatly reducing the stability of the clamping structure 10.

[0069] like Figure 6 and Figure 7 As shown, in one embodiment, the support thickness L of the abutment end of the clamping member 30 located at the discharge end of the conveying component 100 for supporting and abutting with the clamping member 30 located in the clamping area 210 is in the range of 0.8mm-1.2mm. Compared with the design of the clamp applicator of the above-mentioned related art that abuts the clamp by the clamping head, the clamping structure 10 disclosed in the present invention greatly increases the support thickness L of the clamping member 30 located in the clamping area 210, and effectively solves the problem that the clamp in the clamping area 210 shakes during the clamping operation. This greatly improves the support stability of the clamping structure 10 of the present invention during the clamping operation, and avoids the clamping member 30 in the clamping area 210 from shaking during use, thereby greatly improving the use stability of the continuous clip applier 20; at the same time, it also avoids the excessive size of the clamping structure 10 due to the excessive support thickness L of the abutting end of the clamping member 30, thereby ensuring that the clamping structure 10 has good portability.

[0070] like Figure 6 and Figure 7 As shown, in one embodiment, the support thickness L of the abutment end of the clamping member 30 located at the discharge end of the conveying component 100 for supporting and abutting with the clamping member 30 located in the clamping area 210 is 0.95 mm, which not only enables the clamping member 30 at the discharge end of the conveying component 100 to more stably support the clamping member 30 in the clamping area 210, thereby greatly improving the stability of the clamping structure 10, but also ensures that the clamping structure 10 has good portability.

[0071] like Figure 6 and Figure 7As shown, in one embodiment, the continuous clamp applier 20 also includes a stopper 300, which is arranged in the feed trough 110. The stopper 300 is used to support and abut the last clamping member 30 in the feed trough 110. A clamping member abutting surface 310 is formed at one end of the stopper 30 adjacent to the clamping member 30, so that the stopper 300 can push the clamping member 30 in the conveying component 100 into the clamping area 210 while abutting and supporting the clamping member 30 in the clamping area 210, thereby enabling the clamping member 30 in the clamping area 210 to be securely limited in the clamping area 210. Furthermore, the abutting surface 310 of the clamping member is an inwardly concave arc surface to increase the abutting area between the first limiting portion 340 and the clamping member 30, thereby improving the stability of the clamping member 30 in the clamping area 210, thereby preventing the clamping structure 10 from shaking due to the clamping member 30 in the clamping area 210 during use, thereby greatly improving the use stability of the continuous-fire clamp applier 20.

[0072] like Figure 6 and Figure 7 As shown, in one embodiment, a support abutment portion 330 is formed at one end of the terminating member 300 which is away from the clamping member abutment surface 310, and the conveying assembly 100 is used to support the support abutment portion 330 to increase the support abutment area between the conveying assembly 100 and the terminating member 300, so that the conveying assembly 100 can better push the terminating member 300 into the clamping area 210; at the same time, the terminating member 300 can support the clamping member 30 in the clamping area 210 through the conveying assembly 100, so that when the clamping jaw assembly 200 squeezes the clamping member 30, the clamping member 30 can remain stable, so as to improve the use stability of the clamping structure 10 and ensure the safety and smooth progress of the operation.

[0073] like Figure 6 and Figure 7 As shown, in one embodiment, a first limiting portion 340 and a second limiting portion 350 are formed at one end of the terminating member 300 adjacent to the clamping member 30, and the clamping member abutting surface is formed at the end of the first limiting portion 340, and the connecting end of the first limiting portion 340 is fixedly connected to the connecting end of the second limiting portion 350, and there is a third preset angle c between the limiting end of the first limiting portion 340 and the second limiting portion 350, so as to limit the first clamping jaw member 220 and the second clamping jaw member 230, so that the surgeon cannot bring the first clamping jaw member 220 and the second clamping jaw member 230 close to each other, so that the terminating member 300 can effectively remind the surgeon that the clamping member 30 in the clamping structure 10 has been consumed, thereby ensuring the safety and smooth progress of the operation.

[0074] like Figure 7As shown, in one embodiment, the third preset angle c is in the range of 15°-24°, so that the stop member 300 can effectively prevent the first clamping jaw member 220 and the second clamping jaw member 230 from approaching each other.

[0075] like Figure 7 and Fig. 9 As shown, in one embodiment, the termination piece 300 is also formed with a first limiting flange 320, and the discharge end of the conveying component 100 is formed with a limiting groove 120, and the limiting groove 120 is arranged relative to the first limiting flange 320, so that the termination piece 300 is limited in the clamping area 210, so as to prevent the termination piece 300 from falling off from the clamping area 210 and causing safety problems in the operation, thereby ensuring the safety and smooth progress of the operation.

[0076] like Figure 7 and Fig. 9 As shown, in one embodiment, a second limiting flange 140 is formed at the discharge end of the conveying component 100, and the second limiting flange 140 is also formed with a bending edge 141, and a limiting groove is formed on the bending edge 141 to increase the abutment thickness between the second limiting flange 140 and the first limiting flange 320, so that the termination member 300 can be securely limited in the clamping area 210; at the same time, the second limiting flange 140 can also guide and limit the clamping member 30, which not only allows the clamping member 30 in the conveying component 100 to smoothly enter the clamping area 210, but also can limit the clamping member 30 in the clamping area 210, thereby greatly improving the stability of the clamping structure 10.

[0077] like Figure 7 and Fig. 9 As shown, in one embodiment, there is a gap between the bent edge 141 and the second limiting flange 140, so that the bent edge 141 can buffer the terminating piece 300, avoiding excessive impact force between the first limiting flange 320 and the second limiting flange 140, which may cause damage or even destruction to the terminating piece 300 and the conveying component 100, thereby greatly extending the service life of the clamping structure 10.

[0078] like Figure 7 As shown, in one embodiment, a reflective coating 360 is formed on the surface of the terminating piece 300, so that the visibility of the terminating piece 300 is greatly improved under the illumination of the surgical light, so that the surgeon can promptly notice that the clamping piece 30 in the clamping structure 10 has been consumed, further ensuring the safety and smooth progress of the operation.

[0079] The present disclosure further provides a multi-shot clip applier 20, comprising the clip applier structure 10 described in any one of the above embodiments.

[0080] Compared with the prior art, the present invention has at least the following advantages:

[0081] 1. The above-mentioned continuous-fire clip applier 20, since the clamping jaw assembly 200 is arranged at the discharge end of the conveying assembly 100, the conveying assembly 100 is formed with a feeding trough 110, and the feeding trough 110 is used to accommodate the clamping member 30, the clamping jaw assembly 200 is formed with a clamping area 210, and the clamping area 210 is used to accommodate the clamping member 30, the clamping jaw assembly 200 is used to clamp the clamping member 30 located in the clamping area 210, the feeding trough 110 is connected with the clamping area 210, and the conveying assembly 100 is used to push the clamping member 30 0 enters the clamping area 210, so that the conveying assembly 100 can push the clamping member 30 in the feeding trough 110 into the clamping area 210, so that during the operation, the surgeon can clamp the clamping member 30 in the clamping area 210 on the blood vessel or tubular structure of the human body through the clip application structure 10 to ligate and stop bleeding of the blood vessel or tubular structure; and the conveying assembly 100 is also used to support and stop the clamping member 30 in the feeding trough 110, and the clamping member 30 at the discharge end of the conveying assembly 100 0 is abutted against the clamping member 30 located in the clamping area 210, so that the clamping member 30 located at the discharge end of the conveying assembly 100 is supported on the clamping member 30 located in the clamping area 210. Compared with the design of the clamp applicator of the above-mentioned related art that abuts against the clamp by the clamp delivery head, the clamping structure 10 of the present disclosure is directly supported by the clamping member 30 located at the discharge end of the conveying assembly 100 against the clamping member 30 located in the clamping area 210, which greatly improves the clamping member 30 located in the clamping area 210. The support thickness L of 0 effectively solves the problem of shaking of the clamping member 30 in the clamping area 210 during the clamping operation, thereby greatly improving the support stability of the clamping structure 10 disclosed in the present invention during the clamping operation, and avoiding the clamping structure 10 being misaligned or the clamping member 30 falling from the clamping area 210 due to the shaking of the clamping member 30 in the clamping area 210 during use, thereby greatly improving the safety and stability of the use of the continuous-fire clamp applier 20.

[0082] 2. Compared with the design of the clamp applier in the above-mentioned related technology that uses a clamp feeding head to support the clamp in the jaws, the clamping structure 10 disclosed in the present invention can support the clamping member 30 in the clamping area 210 without designing and manufacturing a clamp feeding head, which not only greatly reduces the processing and manufacturing difficulty and production cost of the continuous-fire clamp applier 20 disclosed in the present invention, but also avoids the situation where the use stability and service life of the continuous-fire clamp applier 20 are reduced due to damage or even falling of the clamp feeding head, further improves the use stability of the continuous-fire clamp applier 20, and at the same time greatly extends the service life of the continuous-fire clamp applier 20.

[0083] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the disclosed patent shall be subject to the attached claims.
