Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of continuous firing clip appliers, and in particular to a clip applying structure and a continuous firing clip applier. BACKGROUND

[0002] As a key tool for ligating blood vessels or tubular structures in human surgical operations, clip appliers play a crucial role in the medical field.

[0003] However, the current technical background of the clip applier design, such as patent document CN219480229U, generally has some deficiencies. The mainstream clip appliers on the market mostly use a clip feeding head to abut against the clip in the support jaw to keep the clip in the jaw stable during clamping, but the above design not only increases the manufacturing complexity of the clip applier, but also significantly increases its production cost. More importantly, the abutting support thickness of the clip feeding head of the current clip applier on the market is generally around 0.2 millimeters, which is difficult to provide sufficient support force to the clip in the jaw. Therefore, in actual use, the clip in the jaw often lacks stability, so that the clip in the jaw of the clip applier will shake during use, which can easily lead to inaccurate clamping of the clip or even falling, which not only affects the accuracy and efficiency of the operation, but also can cause medical accidents, greatly reducing the use safety and stability of the clip applier; at the same time, due to the thin thickness of the clip feeding head, the clip feeding head is prone to damage or even fall off during use of the clip applier, not only further reducing the use stability of the clip applier, but also greatly reducing the service life of the clip applier. SUMMARY

[0004] The purpose of the present disclosure is to overcome the deficiencies in the prior art and provide a clip applying structure and a continuous firing clip applier that not only has a simple and compact structure, but also has good use safety and stability.

[0005] The purpose of the present disclosure is achieved by the following technical solutions:

[0006] A clip applying structure for mounting on a continuous firing clip applier, the clip applying structure comprising a conveying assembly and a jaw assembly;

[0007] The clamping jaw assembly is arranged at the discharging end of the conveying assembly. The conveying assembly is formed with a feeding groove for accommodating the clamping member. The clamping jaw assembly is formed with a clamping area for accommodating the clamping member. The clamping jaw assembly is used for clamping the clamping member in the clamping area. The feeding groove and the clamping area are in communication. The conveying assembly is used for pushing the clamping member into the clamping area. The conveying assembly is also used for supporting and preventing the clamping member in the feeding groove from being withdrawn. The clamping member at the discharging end of the conveying assembly is in abutment with the clamping member in the clamping area, so that the clamping member at the discharging end of the conveying assembly is supported by the clamping member in the clamping area.

[0008] In one of the embodiments, the clamping jaw assembly comprises a first clamping jaw member and a second clamping jaw member. The clamping portion of the first clamping jaw member and the clamping portion of the second clamping jaw member jointly form the clamping area. The clamping portion of the first clamping jaw member is arranged at one side of the clamping area and is formed with a first limiting groove in communication with the clamping area. The clamping portion of the second clamping jaw member is arranged at one side of the clamping area and is formed with a second limiting groove in communication with the clamping area. The clamping portion of the first clamping jaw member and the connecting portion of the first clamping jaw member form a first preset clamping angle. The clamping portion of the second clamping jaw member and the connecting portion of the second clamping jaw member form a second preset clamping angle. The angle of the first preset clamping angle is smaller than the angle of the second preset clamping angle.

[0009] In one of the embodiments, there is a preset difference between the angle of the first preset clamping angle and the angle of the second preset clamping angle.

[0010] In one of the embodiments, the preset difference ranges from 8° to 12°.

[0011] In one of the embodiments, the angle of the first preset clamping angle ranges from 0° to 25°.

[0012] In one of the embodiments, the angle of the second preset clamping angle ranges from 10° to 35°.

[0013] In one of the embodiments, the discharging end of the conveying assembly is further formed with an abutment limiting flange. The abutment limiting flange is in abutment and support with the clamping member in the clamping area.

[0014] In one of the embodiments, the support thickness of the abutment end of the clamping member at the discharging end of the conveying assembly for abutment and support with the clamping member in the clamping area ranges from 0.8 mm to 1.2 mm.

[0015] In one of the embodiments, the clip applying structure further comprises a termination member, the termination member is arranged in the feeding groove, the termination member is used to support the last clip abutting in the feeding groove, and an abutting surface of the clip abutting is formed at one end of the termination member adjacent to the clip.

[0016] In one of the embodiments, the termination member is formed with a supporting abutting portion at one end away from the abutting surface of the clip, and the conveying assembly is used to support on the supporting abutting portion.

[0017] In one of the embodiments, the termination member is further formed with a first limiting flange, and the discharging end of the conveying assembly is formed with a limiting groove, the limiting groove is arranged opposite to the first limiting flange.

[0018] A continuous clip applying device comprises the clip applying structure of any one of the above embodiments.

[0019] Compared with the prior art, the present disclosure has at least the following advantages:

[0020] 1. The clip applying structure as described above, since the claw assembly is arranged at the discharging end of the conveying assembly, the conveying assembly is formed with a feeding groove, the feeding groove is used to accommodate the clip, the claw assembly is formed with a clamping area, the clamping area is used to accommodate the clip, the claw assembly is used to clamp the clip in the clamping area, the feeding groove is communicated with the clamping area, and the conveying assembly is used to push the clip in the feeding groove into the clamping area, so that the conveying assembly can push the clip in the feeding groove into the clamping area, and the surgeon can clamp the clip in the clamping area by the clip applying structure to the blood vessel or tubular structure of the human body to knot and stop bleeding of the blood vessel or tubular structure during the operation; and the conveying assembly is further used to support and stop the clip in the feeding groove from retreating, the clip at the discharging end of the conveying assembly abuts against the clip in the clamping area, so that the clip at the discharging end of the conveying assembly is supported on the clip in the clamping area. Compared with the design of the related art that the sending head abuts against and supports the clip, the clip applying structure of the present disclosure directly abuts against and supports the clip in the clamping area by the clip at the discharging end of the conveying assembly, greatly improves the support thickness of the clip in the clamping area, effectively solves the situation that the clip in the clamping area shakes during clamping operation, greatly improves the support stability of the clip applying structure during clamping operation, avoids the phenomenon that the clip in the clamping area shakes during use of the clip applying structure, causes clamping misplacement, or the clip falls from the clamping area, and further greatly improves the use safety and use stability of the continuous clip applying device.

[0021] 2. Compared with the above-mentioned related technologies, which use a chuck head to support the clamps in the jaws, the clamping structure of this disclosure does not require the design and manufacture of a chuck head to support the clamping parts in the clamping area. This not only greatly reduces the processing and manufacturing difficulty and production cost of the continuous firing clamp of this disclosure, but also avoids the situation where the stability and service life of the continuous firing clamp are reduced due to damage or even breakage and fall of the chuck head. This further improves the stability of the continuous firing clamp and greatly extends its service life. Attached Figure Description

[0037] A kind of clamping structure, for installation on continuous firing clamping device, clamping structure includes conveying assembly and jaw assembly;Jaw assembly is located at the delivery end of conveying assembly, conveying assembly is formed with feeding groove, and the clamping member is contained in feeding groove, and jaw assembly is formed with clamping area, and feeding groove is communicated with clamping area, conveying assembly is used to push clamping member into clamping area, and conveying assembly is also used to support the clamping member in feeding groove and stop retreat, the clamping member located at the delivery end of conveying assembly and the clamping member located in clamping area abut, to make the clamping member located at the delivery end of conveying assembly support in the clamping member located in clamping area.

[0038] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in conjunction with specific embodiments:

[0039] As Figures 1 to 10 shown, the continuous firing clamping device 20 of an embodiment is used for installation on continuous firing clamping device 20, and the clamping structure 10 includes conveying assembly 100 and jaw assembly 200;Jaw assembly 200 is located at the delivery end of conveying assembly 100, conveying assembly 100 is formed with feeding groove 110, and the clamping member 30 is contained in feeding groove 110, and jaw assembly 200 is formed with clamping area 210, and clamping area 210 is used to contain clamping member 30, and jaw assembly 200 is used to clamp clamping member 30 located in clamping area 210, and feeding groove 110 is communicated with clamping area 210, and conveying assembly 100 is used to push clamping member 30 into clamping area 210, so that conveying assembly 100 can push clamping member 30 in feeding groove 110 into clamping area 210, so that during the operation, the surgeon can clamp clamping member 30 in clamping area 210 in the blood vessel or tubular structure of the human body by clamping structure 10, so as to ligate and stop bleeding of the blood vessel or tubular structure;And conveying assembly 100 is also used to support and stop the retreat of clamping member 30 in feeding groove 110, and the clamping member 30 located at the delivery end of conveying assembly 100 and the clamping member 30 located in clamping area 210 abut, so that the clamping member 30 located at the delivery end of conveying assembly 100 is supported on the clamping member 30 located in clamping area 210, compared with the design of the above-mentioned related art clamping device through the abutment support of the feeding head, the clamping structure 10 of the present disclosure directly abuts and supports the clamping member 30 located at the delivery end of conveying assembly 100 on the clamping member 30 located in clamping area 210, greatly improves the support thickness L of the clamping member 30 located in clamping area 210, effectively solves the shaking of the clamping member 30 in clamping area 210 during clamping operation, so that the support stability of the clamping structure 10 of the present disclosure during clamping operation is greatly improved, avoiding the phenomenon that the clamping structure 10 is misaligned or the clamping member 30 falls from clamping area 210 due to the shaking of the clamping member 30 in clamping area 210 during use, thereby greatly improving the use safety and use stability of the continuous firing clamping device 20.

[0040] As Figures 1 to 10 Further, compared with the clip applying device of the prior art, the clip applying structure 10 of the present disclosure can support the clips in the clamping area 210 without designing and manufacturing a clip feeding head, which greatly reduces the processing and manufacturing difficulty and production cost of the continuous clip applying device 20 of the present disclosure, avoids the situation that the use stability and service life of the continuous clip applying device 20 are reduced due to the damage or even the falling of the clip feeding head, further improves the use stability of the continuous clip applying device 20, and greatly prolongs the service life of the continuous clip applying device 20.

[0041] In the present embodiment, during the use of the clip applying structure 10, first, the conveying assembly 100 pushes the clips 30 in the feeding groove 110 into the clamping area 210, and the clip 30 at the discharge end of the conveying assembly 100 is supported against the clip 30 in the clamping area 210 under the support of the conveying assembly 100, and the conveying assembly 100 can support the clip 30 at the discharge end of the conveying assembly 100, so that when the main surgeon uses the clip applying structure 10 to ligate and hemostasis the blood vessels or tubular structures of the human body, the clips 30 in the clamping area 210 can be maintained stable, avoiding the phenomenon that the clips 30 in the clamping area 210 are clamped out of position or fall from the clamping area 210 due to the shaking of the clips 30 in the clamping area 210, so that the operation precision and stability of the clip applying structure 10 are improved, and the use stability and safety of the clip applying structure 10 are greatly improved.

[0042] Since the clamping jaw assembly 200 is arranged at the discharging end of the conveying assembly 100, the conveying assembly 100 is formed with a feeding groove 110 for accommodating the clamping member 30, and the clamping jaw assembly 200 is formed with a clamping area 210 for accommodating the clamping member 30. The clamping jaw assembly 200 is used to clamp the clamping member 30 in the clamping area 210. The feeding groove 110 is in communication with the clamping area 210. The conveying assembly 100 is used to push the clamping member 30 in the feeding groove 110 into the clamping area 210, so that the conveying assembly 100 can push the clamping member 30 in the feeding groove 110 into the clamping area 210. During the operation, the surgeon can clamp the clamping member 30 in the clamping area 210 by the clip applying structure 10 to the blood vessel or tubular structure of the human body to stop bleeding by knotting the blood vessel or tubular structure. In addition, the conveying assembly 100 is also used to support and prevent the clamping member 30 in the feeding groove 110 from falling. The clamping member 30 at the discharging 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 discharging end of the conveying assembly 100 is supported by the clamping member 30 in the clamping area 210. Compared with the design of the related art that the feeding head abuts against and supports the clip in the jaw, the clip applying structure 10 of the present disclosure directly abuts against and supports the clamping member 30 in the clamping area 210 by the clamping member 30 at the discharging end of the conveying assembly 100, greatly improves the support thickness L of the clamping member 30 in the clamping area 210, effectively solves the problem of shaking of the clamping member 30 in the clamping area 210 during clamping operation, greatly improves the support stability of the clip applying structure 10 during clamping operation, avoids the phenomenon that the clamping member 30 in the clamping area 210 shakes during use of the clip applying structure 10, resulting in clamping misplacement or falling of the clamping member 30 from the clamping area 210, and thus greatly improves the use safety and stability of the continuous clip applicator 20.

[0043] Compared with the design of the related art that the feeding head supports the clip in the jaw, the clip applying structure 10 of the present disclosure does not need to design and manufacture the feeding head to support the clamping member 30 in the clamping area 210. This not only greatly reduces the manufacturing difficulty and production cost of the continuous clip applicator 20 of the present disclosure, but also avoids the situation that the use stability and service life of the continuous clip applicator 20 are reduced due to damage or even falling of the feeding head, further improves the use stability of the continuous clip applicator 20, and also greatly prolongs the service life of the continuous clip applicator 20.

[0044] It can be understood that the above related art clip applier applies a horizontal force to the clip in the jaw through the abutment of the clip head against the clip in the jaw. However, the clip applying structure 10 of the present disclosure is configured such that the limiting support force direction Y of the clamping piece 30 at the discharge end of the conveying assembly 100 is deviated towards the first clamping jaw piece 220 when the clamping piece 30 at the discharge end of the conveying assembly 100 abuts against the clamping piece 30 in the clamping area 210. As a result, when the clamping jaw assembly 200 is used to press the clamping piece 30 in the clamping area 210, the clamping piece 30 cannot be firmly limited in the clamping area 210, which may cause the clamping jaw assembly 200 to shake or even fall off from the clamping area 210 during the pressing of the clamping piece 30. This greatly reduces the use safety and stability of the clip applying structure 10.

[0045] As shown in Figures 2 to 6 In one embodiment, the clamping jaw assembly 200 includes a first clamping jaw piece 220 and a second clamping jaw piece 230. The clamping portion of the first clamping jaw piece 220 and the clamping portion of the second clamping jaw piece 230 together form a clamping area 210. The clamping portion of the first clamping jaw piece 220 is formed with a first limiting groove 221 on one side of the clamping area 210, which is in communication with the clamping area 210. The clamping portion of the second clamping jaw piece 230 is formed with a second limiting groove 231 on one side of the clamping area 210, which is in communication with the clamping area 210. The clamping portion of the first clamping jaw piece 220 and the connecting portion of the first clamping jaw piece 220 form a first preset angle a. The clamping portion of the second clamping jaw piece and the connecting portion of the second clamping jaw piece form a second preset angle b. The angle of the first preset angle a is smaller than the angle of the second preset angle b. When the clamping piece 30 at the discharge end of the conveying assembly 100 applies a support force to the clamping piece 30 in the clamping area 210, the clamping end of the clamping piece 30 in the clamping area 210 can be firmly limited in the first limiting groove 221 and the second limiting groove 231. As a result, the clamping piece 30 can be firmly limited in the clamping area 210, which greatly improves the operation precision and stability of the clip applying structure 10, and further improves the use stability and safety of the continuous clip applier 20.

[0046] As shown in Figures 2 to 4As shown in the drawings, in one embodiment, the clamping jaw assembly 200 further comprises elastic members (not shown), the connecting portion of the first clamping jaw member 220 is rotationally connected to the conveying assembly 100, the connecting portion of the second clamping jaw member 230 is rotationally connected, and the elastic members are connected to the first clamping jaw member 220 and the second clamping jaw member 230 respectively, so that the connecting portion of the first clamping jaw member 220 is spaced apart from the connecting portion of the second clamping jaw member 230 by a preset clamping angle d, and the clamping member 30 in the conveying assembly 100 can be smoothly pushed into the clamping area 210 by the conveying assembly 100.

[0047] It can be understood that when the preset angle is too large, the clamping jaw assembly 200 cannot firmly limit the clamping member 30 in the clamping area 210, so that when the clamping jaw assembly 200 extrudes the clamping member 30 in the clamping area 210, the clamping member 30 will shake or even fall out of the clamping area 210, which greatly reduces the use stability and safety of the clamping structure 10; and when the preset angle is too small, the conveying assembly 100 cannot smoothly convey the clamping member 30 in the feeding groove 110 into the clamping area 210, which greatly reduces the use stability of the clamping structure 10.

[0048] As shown in the drawings, Figure 4 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 firmly limited in the clamping area 210 due to the preset angle being too large, and also avoid the phenomenon that the conveying assembly 100 cannot push the clamping member 30 into the clamping area 210 due to the preset angle being too small, so that the conveying assembly 100 can smoothly convey the clamping member 30 in the feeding groove 110 into the clamping area 210, and the clamping jaw assembly 200 can also firmly limit the clamping member 30 in the clamping area 210, avoiding the phenomenon that the clamping member 30 shakes when the clamping jaw assembly 200 extrudes the clamping member 30 in the clamping area 210, thereby greatly improving the use stability of the clamping structure 10.

[0049] As shown in the drawings, Figure 2 and Figure 6 In one embodiment, the first clamping jaw member 220 further forms a first guide groove 222 which is in communication with the clamping area 210, and the first guide groove 222 is formed between the first limiting groove 221 and the conveying assembly 100, so that when the conveying assembly 100 pushes the clamping member 30 in the feeding groove 110 into the clamping area 210, the clamping end of the clamping member 30 will enter the first limiting groove 221 along the guide direction of the first guide groove 222 and be limited in the first limiting groove 221, so as to ensure that the conveying assembly 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 be stably "out of clamping", and further improve the use stability of the clamping structure 10.

[0050] As shown in Figure 2 and Figure 6 In one embodiment, the second clamping jaw 230 is further formed with a second guide groove 232 in communication with the clamping area 210, and the second guide groove 232 is formed between the second limiting groove 231 and the conveying assembly 100, so that when the conveying assembly 100 pushes the clamping piece 30 in the feeding groove 110 into the clamping area 210, the clamping end of the clamping piece 30 is guided into the second limiting groove 231 along the guide direction of the second guide groove 232 and is limited in the second limiting groove 231, so that the conveying assembly 100 can ensure that the clamping piece 30 is conveyed to the preset position of the clamping area 210 through the cooperation of the first guide groove 222 and the second guide groove 232, thereby enabling the clamping structure 10 to stably "out of clamping", and further improving the use stability of the clamping structure 10.

[0051] As shown in Figure 2 and Figure 6 In one embodiment, the first clamping jaw 220 includes a first clamping portion 223 and a first connecting portion 224, and the first limiting groove 221 and the first guide groove 222 are both arranged on the first clamping portion 223, the first clamping portion 223 is fixedly connected with the first connecting portion 224, the first connecting portion 224 is rotationally connected with the conveying assembly 100, and the included angle 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 clamping piece 30 at the discharge end of the conveying assembly 100 applies a supporting force to the clamping piece 30 in the clamping area 210, the clamping end of the clamping piece 30 in the clamping area 210 can be firmly limited in the first limiting groove 221, so that the clamping piece 30 can be firmly limited in the clamping area 210, thereby avoiding the phenomenon that the clamping piece 30 shakes or even separates from the clamping area 210 during the extrusion of the clamping piece 30 by the clamping jaw assembly 200, and greatly improving the operation precision and stability of the clamping structure 10. Further, the first clamping portion 223 and the first connecting portion 224 are an integral structure, so as to improve the overall compactness of the first clamping jaw 220.

[0052] As shown in Figure 2 and Figure 4As shown in the drawings, in one embodiment, the second clamping jaw 230 comprises a second clamping portion 233 and a second connecting portion 234, the second limiting groove 231 and the second guide groove 232 are arranged on the second clamping portion 233, the second clamping portion 233 is fixedly connected with the second connecting portion 234, the second connecting portion 234 is rotationally connected with the conveying assembly 100, and the included angle between the length direction of the second clamping portion 233 and the length direction of the second connecting portion 234 is a second preset included angle b, so that when the clamping piece 30 at the discharging end of the conveying assembly 100 applies a supporting force to the clamping piece 30 in the clamping area 210, the clamping end of the clamping piece 30 in the clamping area 210 can be firmly limited in the second limiting groove 231, so that the clamping piece 30 can be firmly limited in the clamping area 210, to avoid the phenomenon that the clamping piece 30 shakes or even separates from the clamping area 210 during the extrusion of the clamping jaw assembly 200 on the clamping piece 30, and further improve the operation precision and stability of the clamping structure 10. Further, the second clamping portion 233 and the second connecting portion 234 are an integral structure, to improve the overall structural compactness of the second clamping jaw 230.

[0053] As shown in the drawings, Figure 2 and Figure 4 in one embodiment, the first clamping portion 223 is inclined relative to the first connecting portion 224 towards the preset direction X, and the second clamping portion 233 is inclined relative to the second connecting portion 234 towards the preset direction X, so that the clamping piece 30 can be firmly limited in the clamping area 210.

[0054] As shown in the drawings, Figure 2 and Figure 4 in one embodiment, the first connecting portion 224 is formed with a first avoiding area (not shown in the drawings), the first avoiding area is arranged opposite to the conveying assembly 100, to avoid that when the first connecting portion 224 rotates towards the direction close to the second connecting portion 234, the first clamping portion 223 cannot rotate to the preset position due to the blocking of the first connecting portion 224 by the conveying assembly 100, so that the first clamping portion 223 can abut against the second clamping portion 233 to jointly extrude the clamping piece 30 in the clamping area 210.

[0055] As shown in the drawings, Figure 2 and Figure 4 in one embodiment, the second connecting portion 234 is formed with a second avoiding area (not shown in the drawings), the second avoiding area is arranged opposite to the conveying assembly 100, to avoid that when the second connecting portion 234 rotates towards the direction close to the first connecting portion 224, the second clamping portion 233 cannot rotate to the preset position due to the blocking of the second connecting portion 234 by the conveying assembly 100, so that the second clamping portion 233 can abut against the first clamping portion 223 to jointly extrude the clamping piece 30 in the clamping area 210.

[0056] As shown in the drawings, Figure 2And Figure 4 As shown in one embodiment, the first end of the first connecting part 224 is fixedly connected with the first clamping part 223, the connecting part between the first end of the first connecting part 224 and the second end of the first connecting part 224 is rotationally connected with the conveying assembly 100, the second end of the second connecting part 234 is fixedly connected with the second clamping part 233, the connecting part between the second end of the second connecting part 234 and the second end of the second connecting part 234 is rotationally connected with the conveying assembly 100, the first end of the elastic member is elastically pressed against the second end of the first connecting part 224, and the second end of the elastic member is elastically pressed against the second connecting part 234, so that the second end of the first connecting part 224 and the second end of the second connecting part 234 are close to each other, the first clamping part 223 and the second clamping part 233 are separated from each other, and the clamping jaw assembly 200 is opened to a preset clamping angle d, so that the conveying assembly 100 can smoothly convey the clamping member 30 in the feeding groove 110 into the clamping area 210.

[0057] As Figure 2 And Figure 4 As shown in one embodiment, there is a preset difference between the first preset clamping angle a and the second preset clamping angle b, so that when the clamping member 30 at the discharge end of the conveying assembly 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 firmly limited in the first limiting groove 221 and the second limiting groove 231, so that the clamping member 30 can be firmly limited in the clamping area 210, to avoid the phenomenon that the clamping member 30 shakes or even falls off the clamping area 210 during the extrusion of the clamping member 30 by the clamping jaw assembly 200, greatly improving the operation precision and stability of the clamping structure 10.

[0058] It can be understood that when the preset difference is too large, the clamping jaw assembly 200 cannot firmly limit the clamping member 30 in the clamping jaw assembly 200, so that when the clamping jaw assembly 200 extrudes the clamping member 30 in the clamping area 210, the clamping member 30 will shake or even fall off the clamping area 210, greatly reducing the use stability of the clamping structure 10; and when the preset difference is too small, the conveying assembly 100 cannot smoothly convey the clamping member 30 in the feeding groove 110 into the clamping area 210, so that the clamping structure 10 cannot smoothly “release the clamping”, greatly reducing the use stability of the clamping structure 10.

[0059] As Figure 4 And Figure 6As shown in the drawings, in one embodiment, the preset difference range is 8°-12°, so as to avoid the phenomenon that the clamping jaw assembly 200 shakes the clamping member 30 in the clamping area 210 when extruding the clamping member 30, and the clamping member 30 falls off the clamping area 210 due to the preset difference being too large, and also avoid the phenomenon that the conveying assembly 100 cannot effectively convey the clamping member 30 in the feeding groove 110 to the clamping area 210 due to the preset difference being too small, thereby greatly improving the use stability of the clamping structure 10.

[0060] As shown in the drawings, Figure 4 and Figure 6 in one embodiment, the preset difference is 10°, so that when the clamping member 30 at the discharge end in the conveying assembly 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 firmly limited in the clamping area 210, which can avoid the phenomenon that the clamping jaw assembly 200 shakes the clamping member 30 in the clamping area 210 when extruding the clamping member 30, and the clamping member 30 falls off the clamping area 210 due to the preset difference being too large, and also avoid the phenomenon that the conveying assembly 100 cannot effectively convey the clamping member 30 in the feeding groove 110 to the clamping area 210 due to the preset difference being too small, thereby greatly improving the use stability of the clamping structure 10.

[0061] As shown in the drawings, Figure 4 and Figure 6 in one embodiment, the angle range of the first preset included angle a is 0°-25°, so that when the clamping member 30 at the discharge end in the conveying assembly 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 firmly limited in the first limiting groove 221, thereby improving the use stability of the clamping structure 10.

[0062] As shown in the drawings, Figure 4 and Figure 6 in one embodiment, the angle of the first preset included angle a is 7.5°, so that when the clamping member 30 at the discharge end in the conveying assembly 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 firmly limited in the first limiting groove 221, thereby improving the use stability of the clamping structure 10.

[0063] As shown in the drawings, Figure 4 and Figure 6 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 assembly 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 firmly limited in the second limiting groove 231, thereby further improving the use stability of the clamping structure 10.

[0064] As shown in Figure 6 and Figure 9 shown, in one embodiment, the angle of the second preset included angle b is 17.5°, so that when the clamping piece 30 at the discharge end in the conveying assembly 100 abuts against the clamping piece 30 in the support clamping area 210, the clamping end of the clamping piece 30 in the clamping area 210 can be more firmly limited in the second limiting groove 231, so as to improve the use stability of the clamping structure 10.

[0065] As shown in Figure 6 and Figure 9 shown, in one of the embodiments, the discharge end of the conveying assembly 100 is further formed with an abutting limiting flange 130, which abuts against and supports the clamping piece 30 in the clamping area 210, so that the clamping piece 30 in the clamping area 210 can be firmly limited in the clamping area 210 through the cooperation between the clamping piece 30 at the discharge end of the conveying assembly 100 and the abutting limiting flange 130, so that the use stability of the clamping structure 10 is greatly improved; at the same time, when the conveying assembly 100 conveys the clamping piece 30 into the clamping area 210, the abutting limiting flange 130 can also play a role of guiding and limiting.

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

[0067] As shown in Figure 6 and Figure 7 shown, in one embodiment, the abutting limiting flange 130 is in an arc-shaped structure, which not only enables the abutting limiting flange 130 to firmly limit the clamping piece 30 in the clamping area 210, but also buffers the support force applied by the clamping piece 30 at the discharge end of the conveying assembly 100 to the clamping piece 30 in the clamping area 210, so as to avoid the phenomenon that the clamping piece 30 is damaged or even broken due to excessive support force, and greatly improves the use stability of the clamping structure 10.

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

[0069] As shown in Figure 6 and Figure 7 , in one embodiment, the support thickness L of the abutting end of the clamping piece 30 at the discharge end of the conveying assembly 100 for supporting abutting with the clamping piece 30 in the clamping area 210 ranges from 0.8mm to 1.2mm. Compared with the design of the related art clamping device in which the clamping piece is supported by the abutting end of the feeding head, the clamping structure 10 of the present disclosure greatly improves the support thickness L of the clamping piece 30 in the clamping area 210, effectively solves the problem of shaking of the clamping piece in the clamping area 210 during clamping operation, greatly improves the support stability of the clamping structure 10 during clamping operation, avoids the problem of shaking of the clamping piece 30 in the clamping area 210 during use of the clamping structure 10, thereby greatly improving the use stability of the continuous clamping device 20; at the same time, it also avoids the problem of excessive volume of the clamping structure 10 due to excessive support thickness L of the abutting end of the clamping piece 30, so as to ensure good use portability of the clamping structure 10.

[0070] As shown in Figure 6 and Figure 7 , in one embodiment, the support thickness L of the abutting end of the clamping piece 30 at the discharge end of the conveying assembly 100 for supporting abutting with the clamping piece 30 in the clamping area 210 is 0.95mm. Not only can the clamping piece 30 at the discharge end of the conveying assembly 100 more stably support the clamping piece 30 in the clamping area 210, thereby greatly improving the use stability of the clamping structure 10, but also can ensure good use portability of the clamping structure 10.

[0071] As shown in Figure 6 and Figure 7As shown in the drawings, in one of the embodiments, the continuous clip applier 20 further comprises a termination piece 300 arranged in the feeding groove 110, the termination piece 300 is used to support the last clip 30 in the feeding groove 110, and the termination piece 300 is formed with a clip abutting surface 310 adjacent to one end of the clip 30, so that the termination piece 300 can push the clip 30 in the conveying assembly 100 into the clamping area 210 while abutting and supporting the clip 30 in the clamping area 210, thereby enabling the clip 30 in the clamping area 210 to be firmly limited in the clamping area 210. Further, the clip abutting surface 310 is an inner concave arc surface, so as to increase the abutting area between the first limiting portion 340 and the clip 30, so that the stability of the clip 30 in the clamping area 210 is improved, avoiding the situation that the clip 30 in the clamping area 210 shakes due to the shaking of the clip 30 in the clamping area 210 during use of the clip applying structure 10, thereby greatly improving the use stability of the continuous clip applier 20.

[0072] As shown in the drawings, Figure 6 and Figure 7 in one of the embodiments, the termination piece 300 is formed with a supporting abutting portion 330 at one end away from the clip abutting surface 310, and the conveying assembly 100 is used to support the supporting abutting portion 330, so as to increase the supporting abutting area between the conveying assembly 100 and the termination piece 300, so that the conveying assembly 100 can better push the termination piece 300 into the clamping area 210; at the same time, the termination piece 300 can support the clip 30 in the clamping area 210 through the conveying assembly 100, so that the clip 30 can remain stable when the clamping jaw assembly 200 extrudes the clip 30, so as to improve the use stability of the clip applying structure 10 and ensure the safety and smooth progress of the operation.

[0073] As shown in the drawings, Figure 7 and Figure 7 in one of the embodiments, the termination piece 300 is formed with a first limiting portion 340 and a second limiting portion 350 adjacent to one end of the clip 30, the clip abutting surface is formed at the end of the first limiting portion 340, the connecting end of the first limiting portion 340 and the connecting end of the second limiting portion 350 are fixedly connected, and there is a third preset included 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 piece 220 and the second clamping jaw piece 230, so that the surgeon cannot make the first clamping jaw piece 220 and the second clamping jaw piece 230 approach each other, so that the termination piece 300 can effectively remind the surgeon that the clip 30 in the clip applying structure 10 has been consumed, and ensure the safety and smooth progress of the operation.

[0074] As shown in the drawings, Figure 9As shown in the drawings, in one of the embodiments, the third preset included angle c is in the range of 15°-24°, so that the termination member 300 can effectively prevent the first jaw member 220 and the second jaw member 230 from approaching each other.

[0075] As shown in the drawings, Figure 7 and Figure 9 As shown in the drawings, in one of the embodiments, the termination member 300 is further formed with a first limiting flange 320, and the discharge end of the delivery assembly 100 is formed with a limiting groove 120, which is oppositely arranged with the first limiting flange 320, so that the termination member 300 is limited in the clamping area 210, avoiding the termination member 300 from falling out of the clamping area 210 and causing safety problems in the operation, ensuring the safety and smooth progress of the operation.

[0076] As shown in the drawings, Figure 7 and Figure 9 As shown in the drawings, in one of the embodiments, the discharge end of the delivery assembly 100 is formed with a second limiting flange 140, and the second limiting flange 140 is further formed with a bent edge 141, and a limiting groove is formed in the bent edge 141, so as to increase the abutting thickness of the second limiting flange 140 and the first limiting flange 320, so that the termination member 300 can be firmly limited in the clamping area 210; at the same time, the second limiting flange 140 can also guide and limit the clamping member 30, not only enabling the clamping member 30 in the delivery assembly 100 to smoothly enter the clamping area 210, but also limiting the clamping member 30 in the clamping area 210, thereby greatly improving the use stability of the clip applying structure 10.

[0077] As shown in the drawings, Figure 7 and ​ As shown in the drawings, in one of the embodiments, there is a gap between the bent edge 141 and the second limiting flange 140, so that the bent edge 141 can buffer the termination member 300, avoiding the impact force between the first limiting flange 320 and the second limiting flange 140 being too large to cause damage or even damage to the termination member 300 and the delivery assembly 100, thereby greatly prolonging the service life of the clip applying structure 10.

[0078] As shown in the drawings, ​ As shown in the drawings, in one of the embodiments, the surface of the termination member 300 is formed with a reflective coating 360, so that under the irradiation of the operating lamp, the visibility of the termination member 300 is greatly improved, enabling the lead surgeon to promptly notice that the clamping member 30 in the clip applying structure 10 has been consumed, further ensuring the safety and smooth progress of the operation.

[0079] The present disclosure also provides a continuous clip applier 20, which comprises the clip applying structure 10 described in any of the above embodiments.

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

[0081] 1. In the aforementioned continuous-fire clamping device 20, the gripper assembly 200 is located at the discharge end of the conveying assembly 100. The conveying assembly 100 has a feeding trough 110 for accommodating the clamping member 30. The gripper assembly 200 has a clamping area 210 for accommodating the clamping member 30. The gripper assembly 200 is used to clamp the clamping member 30 located within the clamping area 210. The feeding trough 110 communicates with the clamping area 210. The conveying assembly 100 is used to push the clamping member 30. The clamping element 30 is inserted into the clamping area 210 by the conveying assembly 100, allowing the clamping component 30 in the feeding trough 110 to be pushed into the clamping area 210. This enables the surgeon to clamp the clamping component 30 in the clamping area 210 onto a blood vessel or tubular structure during surgery using the clamping structure 10, thus ligating and stopping bleeding. The conveying assembly 100 also supports and prevents the clamping component 30 in the feeding trough 110 from retracting. The clamping component 30 is located at the discharge end of the conveying assembly 100. The clamping structure 10 of this invention abuts against the clamping member 30 located within the clamping area 210, so that the clamping member 30 at the discharge end of the conveying assembly 100 is supported by the clamping member 30 located within the clamping area 210. Compared with the clamping device of the aforementioned related technologies, which uses a feeding chuck to abut against the supporting clamp, the clamping structure 10 of this invention directly abuts against and is supported by the clamping member 30 located within the clamping area 210 via the clamping member 30 at the discharge end of the conveying assembly 100, greatly improving the clamping member 30 within the clamping area 210. The support thickness L of 0 effectively solves the problem of the clamping member 30 in the clamping area 210 shaking during the clamping operation, which greatly improves the support stability of the clamping structure 10 during the clamping operation. It avoids the phenomenon of clamping misalignment or the clamping member 30 falling out of the clamping area 210 due to shaking of the clamping member 30 in the clamping area 210 during use, thereby greatly improving the safety and stability of the continuous firing clamping device 20.

[0082] 2. Compared with the above-mentioned related technologies, which use a chuck head to support the clamps in the jaws, the clamping structure 10 of this disclosure does not require the design and manufacture of a chuck head to support the clamping member 30 in the clamping area 210. This not only greatly reduces the processing and manufacturing difficulty and production cost of the continuous-fire clamping device 20 of this disclosure, but also avoids the situation where the stability and service life of the continuous-fire clamping device 20 are reduced due to damage or even breakage and fall of the chuck head. This further improves the stability of the continuous-fire clamping device 20 and greatly extends its service life.

[0083] The above-described embodiments are merely illustrative of several embodiments of the present disclosure, which are described in a more specific and detailed manner, but should not be construed as limiting the scope of the patent disclosure. It should be noted that for those skilled in the art, several modifications 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 patent of the present disclosure should be subject to the appended claims.
