Technical Field
[0001] Embodiments of this disclosure relate to a clamp and a clamping clamp. Background Technology
[0002] In surgical procedures, clamps are commonly used to ligate blood vessels or tissues to reduce bleeding. This ligation method is simple and can be performed quickly. The clamps are typically applied to the blood vessels or tissues using clamping forceps. The clamps are assembled into the clamping forceps. During use, the forceps are driven to deliver the clamps into the jaw assembly. The clamps in the jaw assembly are then aligned with the tissue or blood vessel to be clamped. The jaw assembly is then driven to close, thus closing the clamps and applying them to the tissue or blood vessel to stop bleeding. Utility Model Content
[0003] This disclosure provides a clamping magazine and clamping clamp. By ensuring that the projection of the first end protrusion of one of two adjacent clamps in the magazine in a third direction at least partially coincides with the projection of the second end protrusion of the other clamp in a third direction, the contact area between the two adjacent clamps can be increased, improving the stability of the arrangement of multiple clamps in the second direction and the stability of movement along the second direction, ensuring the posture of the clamps in the magazine and the state of the clamps after exiting the magazine.
[0004] At least one embodiment of this disclosure provides a clamping chamber, comprising: a chamber body including a clamping cavity, the clamping cavity including a clamping channel including an inlet and an outlet, the inlet pointing towards the outlet along a first direction; and at least two clamps located within the clamping cavity, the at least two clamps being arranged along a second direction intersecting the first direction, wherein each clamp includes a first clamping arm and a second clamping arm, the first clamping arm and the second clamping arm being rotatably connected, the first clamping arm including a first clamping arm body and a first end protrusion and a second end protrusion connected to the same end of the first clamping arm body, the first end protrusion and the second end protrusion both protruding from the first clamping arm body in the second direction, and the first end protrusion and the second end protrusion being located on both sides of the first clamping arm body in the second direction; in two adjacent clamps, the projection of the first end protrusion of one clamp in a third direction at least partially coincides with the projection of the second end protrusion of the other clamp in the third direction, the third direction being perpendicular to both the first direction and the second direction.
[0005] For example, in a clamp provided in an embodiment of this disclosure, the first end protrusion includes a first coupling portion, and the second end protrusion includes a second coupling portion. In two adjacent clamps, the first coupling portion of one clamp is coupled to the second coupling portion of the other clamp. The coupled first coupling portion and the coupled second coupling portion abut against each other in the third direction, and the coupled first coupling portion and the coupled second coupling portion are configured to move relative to each other in the first direction.
[0006] For example, in a clamping compartment provided in an embodiment of this disclosure, the first coupling portion and the second coupling portion coupled to each other have a contact area, the contact area is a continuous area, the contact area extends along the first direction and / or along the second direction, or the contact area includes a plurality of discontinuous sub-contact areas, the plurality of sub-contact areas being arranged along the first direction.
[0007] For example, in a clamping compartment provided in one embodiment of this disclosure, the shape of the contact area includes at least one of a surface, a line, and a point.
[0008] For example, in a clamp provided in an embodiment of this disclosure, one of the mutually coupled first coupling portion and the second coupling portion includes at least two sub-coupling portions, and at least a portion of the other is located between the two sub-coupling portions; or the mutually coupled first coupling portion and the second coupling portion each include at least two first sub-coupling portions and at least two second sub-coupling portions, and the two first sub-coupling portions and the two second sub-coupling portions are inserted into each other.
[0009] For example, in a clamping compartment provided in an embodiment of this disclosure, the first end protrusion further includes a first limiting portion, the first coupling portion and the first limiting portion define a first coupling space, the second end protrusion further includes a second limiting portion, the second coupling portion and the second limiting portion define a second coupling space, the at least two clamps are arranged adjacent to each other in the second direction, the two adjacent clamps include a first clamp and a second clamp, the first coupling portion of the first clamp and the second coupling portion of the second clamp are coupled to each other, the first coupling space of the first clamp at least partially accommodates the second coupling portion of the second clamp, and the second coupling space of the second clamp at least partially accommodates the first coupling portion of the first clamp.
[0010] For example, in a clamping compartment provided in an embodiment of this disclosure, the first coupling portion and the first limiting portion of the first end protrusion are integrally connected or spaced apart; the second coupling portion and the second limiting portion of the second end protrusion are integrally connected or spaced apart.
[0011] For example, in a clamping compartment provided in an embodiment of this disclosure, the direction in which the first coupling portion protruding at the first end of the clamp points to the first limiting portion is opposite to the direction in which the second coupling portion protruding at the second end points to the second limiting portion.
[0012] For example, in a clamping chamber provided in one embodiment of this disclosure, in the second direction, the first clamp is closer to the clamping channel than the second clamp, the first limiting portion of the first end protruding of the first clamp is located on the side of the first coupling portion closer to the outlet, and the second limiting portion of the second end protruding of the second clamp is located on the side of the second coupling portion away from the outlet.

[0014] For example, in a clamping compartment provided in an embodiment of this disclosure, the first end protrusion includes a first abutting surface away from the first clamping arm body, and the second end protrusion includes a second abutting surface away from the first clamping arm body. The at least two clamps are arranged adjacent to each other in the second direction. The two adjacent clamps include a first clamp and a second clamp. The first end protrusion of the first clamp and the second end protrusion of the second clamp cooperate with each other. Between the first clamp and the second clamp, the first abutting surface of the first clamp abuts against the first clamping arm body of the second clamp, and the second abutting surface of the second clamp abuts against the first clamping arm body of the first clamp.
[0015] For example, in a clamping magazine provided in one embodiment of this disclosure, the first end protrusion includes a first abutting surface away from the first clamping arm body, the first abutting surface being configured to abut against the clamping arm of the jaw assembly after the clamp is fed from the outlet via the clamping channel to the jaw assembly, and the second end protrusion includes a second abutting surface away from the second clamping arm body, the second abutting surface being configured to abut against the clamping arm of the jaw assembly after the clamp is fed from the outlet via the clamping channel to the jaw assembly.
[0016] For example, in a clamping compartment provided in one embodiment of this disclosure, the shapes of the first end protrusion and the second end protrusion include L-shape.
[0017] For example, in a clamping compartment provided in an embodiment of this disclosure, the second clamping arm includes a second clamping arm body and a third end protrusion and a fourth end protrusion connected to the same end of the second clamping arm body. The third end protrusion and the fourth end protrusion both protrude from the second clamping arm body in the second direction, and the third end protrusion and the fourth end protrusion are located on both sides of the second clamping arm body in the second direction. In two adjacent clamps, the second clamping arm body of one clamp abuts against the third end protrusion or the fourth end protrusion of the other clamp.
[0018] For example, in a clamping compartment provided in one embodiment of this disclosure, in two adjacent clamps, the projection of the third end protrusion of one clamp in the third direction at least partially overlaps with the projection of the fourth end protrusion of the other clamp in the third direction.

[0040] This disclosure provides a clamping magazine and clamping clamps. The clamping magazine includes a magazine body and at least two clamps. The magazine body includes a clamping cavity, which includes a clamping channel with an inlet and an outlet, the inlet pointing towards the outlet in a first direction. At least two clamps are located within the clamping cavity and are arranged along a second direction intersecting the first direction. Each clamp includes a first clamping arm and a second clamping arm, which are rotatably connected. The first clamping arm includes a first clamping arm body and a first end protrusion and a second end protrusion connected to the same end of the first clamping arm body. Both the first end protrusion and the second end protrusion protrude from the first clamping arm body in the second direction and are located on opposite sides of the first clamping arm body in the second direction. In two adjacent clamps, the projection of the first end protrusion of one clamp in a third direction at least partially coincides with the projection of the second end protrusion of the other clamp in a third direction, the third direction being perpendicular to both the first and second directions. This allows the first end protrusion and / or the second end protrusion to have a larger size in the first direction, which can increase the contact area between two adjacent clamps, improve the stability of the arrangement of multiple clamps in the second direction and the stability of movement in the second direction, ensure the posture of the clamps in the clamping chamber and ensure the state of the clamps after they are removed from the chamber.
[0041] The clamping chamber and clamping forceps provided in the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.
[0042] This disclosure provides a clamping magazine.

[0043] like Figures 1 to 6As shown, the clamping chamber 100 includes a chamber body 110 and at least two clamps 120. The chamber body 110 includes a clamping cavity 111, which includes a clamping channel 1110. The clamping channel 1110 includes an inlet 1110a and an outlet 1110b, with the inlet 1110a pointing towards the outlet 1110b along a first direction X. At least two clamps 120 are located within the clamping cavity 111 and are arranged along a second direction Y, which intersects with the first direction X. Each clamp 120 includes a first clamping arm 121 and a second clamping arm 122, which are rotatably connected. The first clamping arm 121 includes a first clamping arm body 1210 and a first end protrusion 1211 and a second end protrusion 1212 connected to the same end of the first clamping arm body 1210. Both the first end protrusion 1211 and the second end protrusion 1212 protrude from the first clamping arm body 1210 in the second direction Y, and are located on opposite sides of the first clamping arm body 1210 in the second direction Y. For example, the first end protrusion 1211 and the second end protrusion 1212 at least partially overlap in the second direction Y. For example, the projections of the first end protrusion 1211 and the second end protrusion 1212 onto the plane containing the first direction X and the third third direction Z at least partially overlap, where the third third direction Z is perpendicular to both the first direction X and the second direction Y.
[0044] like Figures 1 to 6 As shown, in two adjacent clips 120, the projection of the first end protrusion 1211 of one clip 120 onto the third direction Z at least partially coincides with the projection of the second end protrusion 1212 of the other clip 120 onto the third direction Z. That is, in two adjacent clips 120, the projection of the first end protrusion 1211 of one clip 120 onto the plane containing the first direction X and the second direction Y at least partially coincides with the projection of the second end protrusion 1212 of the other clip 120 onto that plane.
[0045] Figure 3 The diagram schematically illustrates that the clamping compartment 100 includes three clamps 120, namely a first clamp 1201, a second clamp 1202, and a third clamp 1203. For example, as... Figure 1 and Figure 2As shown, in the initial state, the first clamp 1201 is located within the clamping channel 1110. Under the action of the clamping mechanism, the first clamp 1201 can be output from the outlet 1110b to the jaw assembly via the clamping channel 1110. For example, after the first clamp 1201 completes its transport, the second clamp 1202 can move along the second direction Y into the clamping channel 1110 to achieve the transport of the second clamp 1202. Similarly, multiple clamps 120 arranged along the second direction Y within the clamping chamber 100 can sequentially move to the clamping channel 1110 and be output from the outlet 1110b to the jaw assembly. It is evident that the above-mentioned transport places high demands on the stability of the arrangement of the multiple clamps 120 in the second direction Y and the stability of their movement along the second direction Y. For a description of the clamping mechanism and the jaw assembly, please refer to the following text. This embodiment does not limit the number of clamps 120 within the clamping chamber 100. For example, it can also be two or four.
[0046] In the clamping magazine 100 provided in this embodiment, by making the projections of the first end protrusion 1211 and the second end protrusion 1212 of two adjacent clamps 120 at least partially overlap in the third direction Z, the first end protrusion 1211 and / or the second end protrusion 1212 can have a larger size in the first direction X. The plurality of clamps 120 within the clamping magazine 100 are arranged along the second direction Y. By making the first end protrusion 1211 and / or the second end protrusion 1212 have a larger size in the first direction X, the contact area between two adjacent clamps 120 arranged along the second direction Y can be increased, improving the stability of the plurality of clamps 120 arranged in the second direction Y and the stability of movement along the second direction Y, ensuring the posture of the clamps 120 within the clamping magazine 100 and ensuring the state of the clamps 120 after exiting the magazine. Furthermore, due to the increase in the size of the first end protrusion 1211 and / or the second end protrusion 1212 in the first direction X, the size of the first end protrusion 1211 and / or the second end protrusion 1212 in the third direction Z can remain unchanged or even be reduced, which facilitates the structural design of the clip 120 and the stacking design of multiple clips 120, and avoids the size of the first end protrusion 1211 and the second end protrusion 1212 in the third direction Z from occupying the space of the clip compartment 100.
[0047] In some examples, such as Figures 3 to 6As shown, the first end protrusion 1211 includes a first coupling portion 12111, and the second end protrusion 1212 includes a second coupling portion 12121. In two adjacent clips 120, the first coupling portion 12111 of one clip 120 (e.g., the first clip 1201) is coupled to the second coupling portion 12121 of the other clip 120 (e.g., the second clip 1202). The coupled first coupling portion 12111 and the coupled second coupling portion 12121 abut against each other in the third direction Z, and the coupled first coupling portion 12111 and the coupled second coupling portion 12121 are configured to move relative to each other in the first direction X. The abutment arrangement of the coupled first coupling portion 12111 and the coupled second coupling portion 12121 in the third direction Z can further improve the stability of the arrangement of multiple clips 120 in the second direction Y and the stability of movement in the second direction Y, and also facilitates the assembly of multiple clips 120, making it easier to guide and ensure that multiple clips 120 are assembled in place. Furthermore, by enabling the first coupling portion 12111 and the second coupling portion 12121 to move relative to each other along the first direction X, the first end protrusion 1211 and the second end protrusion 1212 of two adjacent clips 120 can be prevented from affecting each other, and the clips 120 located in the clip feeding channel 1110 can be smoothly output from the outlet 1110b.
[0048] In some examples, such as Figure 3 and Figure 4 As shown, the mutually coupled first coupling portion 12111 and second coupling portion 12121 have contact areas R01. For example, the contact area R01 is a continuous region. For example, the contact area R01 extends along a first direction X and a second direction Y. For example, the shape of the contact area R01 is planar. For example, the shape of the contact area R01 is a rectangular plane, for example, a rounded rectangular plane. For example, the projection of the contact area R01 onto the second direction Y is a straight line segment, that is, the projection of the contact area R01 onto the plane containing the first direction X and the third direction Z is a straight line segment. For example, the size of the contact area R01 along the first direction X is greater than or equal to the size along the second direction Y. Thus, the contact area R01 of the mutually coupled first coupling portion 12111 and second coupling portion 12121 can have a larger area, improving the stability of the arrangement of the multiple clips 120 in the second direction Y and the stability of movement along the second direction Y, and making the movement of the first coupling portion 12111 and the second coupling portion 12121 along the first direction X more stable.
[0049] In some examples, such as Figures 3 to 6As shown, the first end protrusion 1211 further includes a first limiting portion 12112, and the first coupling portion 12111 and the first limiting portion 12112 define a first coupling space S01. The second end protrusion 1212 further includes a second limiting portion 12122, and the second coupling portion 12121 and the second limiting portion 12122 define a second coupling space S02. At least two clips 120 are sequentially arranged adjacent to each other in the second direction Y, and the two adjacent clips 120 include a first clip 1201 and a second clip 1202. The first coupling portion 12111 of the first clip 1201 is coupled to the second coupling portion 12121 of the second clip 1202. The first coupling space S01 of the first clip 1201 accommodates at least a portion of the second coupling portion 12121 of the second clip 1202, and the second coupling space S02 of the second clip 1202 accommodates at least a portion of the first coupling portion 12111 of the first clip 1201. The first limiting portion 12112 and the second limiting portion 12122 can respectively increase the size of the first end protrusion 1211 and the second end protrusion 1212. For example, the size of the first end protrusion 1211 and the second end protrusion 1212 along the first direction X and the third direction Z can be increased. This increases the contact area between two adjacent clips 120, further improving the stability of the arrangement of multiple clips 120 in the second direction Y and the stability of movement along the second direction Y. In addition, the aforementioned first coupling space S01 and second coupling space S02 facilitate the assembly of multiple clips 120, making it easier to guide and ensure that the multiple clips 120 are assembled in place.
[0050] In some examples, such as Figures 3 to 6 As shown, the first coupling portion 12111 and the first limiting portion 12112 of the first end protrusion 1211 are integrally connected. For example, the second coupling portion 12121 and the second limiting portion 12122 of the second end protrusion 1212 are integrally connected. The integrally connected first end protrusion 1211 and second end protrusion 1212 simplify the structural design. Of course, this embodiment does not limit the design and can be customized according to requirements. For example, the first coupling portion 12111 and the first limiting portion 12112 of the first end protrusion 1211 are spaced apart. For example, the second coupling portion 12121 and the second limiting portion 12122 of the second end protrusion 1212 are spaced apart. The spaced-apart first end protrusion 1211 and second end protrusion 1212 allow for more flexible design of the first coupling portion 12111, the first limiting portion 12112, the second coupling portion 12121, and the second limiting portion 12122, which can be flexibly configured according to the shape of the first clamping arm body 1210.
[0051] In some examples, such as Figures 3 to 6As shown, the first end protrusion 1211 and the second end protrusion 1212 are L-shaped. For example, the first coupling portion 12111 and the first limiting portion 12112 are two sides of the L-shape. For example, the second coupling portion 12121 and the second limiting portion 12122 are two sides of the L-shape. Thus, the dimensions of the first end protrusion 1211 and the second end protrusion 1212 along the first direction X can be increased, while maintaining the dimension along the third direction Z. Furthermore, it facilitates the arrangement of multiple clips 120 along the second direction Y. For example, the dimension of the first coupling portion 12111 of the first end protrusion 1211 of the clip 120 located in the clip compartment 100 along the first direction X is greater than the dimension of the first limiting portion 12112 along the first direction X. For example, the dimension of the first coupling portion 12111 of the first end protrusion 1211 of the clip 120 located in the clip compartment 100 along the third direction Z is smaller than the dimension of the first limiting portion 12112 along the third direction Z. For example, the dimensional relationship between the second coupling portion 12121 and the second limiting portion 12122 of the second end protrusion 1212 is similar to that of the first end protrusion 1211, and will not be described in detail here.
[0052] In some examples, such as Figures 3 to 6 As shown, the direction in which the first coupling portion 12111 of the first end protrusion 1211 of the clip 120 points to the first limiting portion 12112 is opposite to the direction in which the second coupling portion 12121 of the second end protrusion 1212 points to the second limiting portion 12122. For example, in the second direction Y, the first clip 1201 is closer to the feeding channel 1110 than the second clip 1202. The first limiting portion 12112 of the first end protrusion 1211 of the first clip 1201 is located on the side of the first coupling portion 12111 closer to the outlet 1110b, and the second limiting portion 12122 of the second end protrusion 1212 of the second clip 1202 is located on the side of the second coupling portion 12121 away from the outlet 1110b. The first clamp 1201 and the second clamp 1202 are arranged along the second direction Y. This arrangement achieves a tight arrangement of the first clamp 1201 and the second clamp 1202, while also preventing the second end protrusion 1212 of the second clamp 1202 from affecting the first clamp 1201's output from the outlet 1110b via the clamping channel 1110 along the first direction X, thus ensuring that each clamp 120 smoothly exits the clamping chamber 100. For example, the shape of the first end protrusion 1211 of the clamp 120 is basically the same as the shape of the second end protrusion 1212, only their relative positions are reversed.
[0053] In some examples, such as Figure 3 and Figure 4As shown, the first limiting portion 12112 of the first clip 1201 and the second coupling portion 12121 of the second clip 1202 can be detachably abutted. For example, the second limiting portion 12122 of the second clip 1202 and the first coupling portion 12111 of the first clip 1201 can be detachably abutted. This allows the arrangement of the first clip 1201 and the second clip 1202 in the first direction X to be as compact as possible, reducing the size of the clip compartment 100, especially the size in the first direction X. Furthermore, the aforementioned abutment arrangement facilitates the assembly of the first clip 1201 and the second clip 1202, making it easier to guide and ensure that the first clip 1201 and the second clip 1202 are properly assembled.
[0054] In some examples, such as Figures 3 to 6 As shown, the first end protrusion 1211 includes a first abutting surface 12113 away from the first clamping arm body 1210. For example, the second end protrusion 1212 includes a second abutting surface 12123 away from the first clamping arm body 1210. At least two clips 120 are sequentially arranged adjacent to each other in the second direction Y. The two adjacent clips 120 include adjacent first clips 1201 and second clips 1202. The first end protrusion 1211 of the first clip 1201 and the second end protrusion 1212 of the second clip 1202 cooperate with each other. Between the first clip 1201 and the second clip 1202, the first abutting surface 12113 of the first clip 1201 abuts against the first clamping arm body 1210 of the second clip 1202, and the second abutting surface 12123 of the second clip 1202 abuts against the first clamping arm body 1210 of the first clip 1201. The first end protrusion 1211 and the second end protrusion 1212 have larger dimensions. The first end protrusion 1211 and the second end protrusion 1212 abut against the first clamping arm body 1210 of the adjacent clamp 120, which can increase the contact area between the two adjacent clamps 120, improve the stability of the multiple clamps 120 arranged in the second direction Y and the stability of movement along the second direction Y, ensure the posture of the clamps 120 in the clamping chamber 100 and ensure the state of the clamps 120 after exiting the chamber.
[0055] Figure 7 A partial structural schematic diagram from one perspective of the clamp after it exits the clamping chamber according to an embodiment of this disclosure; Figure 8 This is a partial structural schematic diagram from one perspective of the clamp after it exits the clamping chamber, as provided in an embodiment of this disclosure.
[0056] In some examples, such as Figures 3 to 8As shown, the first end protrusion 1211 includes a first abutment surface 12113 away from the first clamping arm body 1210. The first abutment surface 12113 is configured to abut against the clamping arm of the jaw assembly 220 after the clamp 120 is fed from the outlet 1110b to the jaw assembly 220 via the clamping channel 1110. For example, the second end protrusion 1212 includes a second abutment surface 12123 away from the second clamping arm body 1220. The second abutment surface 12123 is configured to abut against the jawing arm of the jaw assembly 220 after the clamp 120 is fed from the outlet 1110b to the jaw assembly 220 via the clamping channel 1110. The first end protrusion 1211 and the second end protrusion 1212 have larger dimensions, thereby increasing the contact area between the first contact surface 12113 and the second contact surface 12123 and the jaw assembly 220. This ensures the stability and posture of the clamp 120 within the jaw assembly 220 and prevents the clamp 120 from twisting or shaking due to a small contact area with the jaw assembly 220 after it is delivered to the jaw assembly 220.
[0057] Figures 9 to 11 This is another partial cross-sectional schematic diagram of the first end protrusion and the second end protrusion of two adjacent clips provided in an embodiment of this disclosure.
[0058] In some examples, such as Figures 9 to 11 As shown, the first end protrusion 1211 includes a first coupling portion 12111, and the second end protrusion 1212 includes a second coupling portion 12121. In two adjacent clips 120, the first coupling portion 12111 of one clip 120 is coupled to the second coupling portion 12121 of the other clip 120, and the coupled first coupling portion 12111 and the coupled second coupling portion 12121 abut against each other in the third direction Z. The coupled first coupling portion 12111 and the coupled second coupling portion 12121 have a contact area R01.
[0059] In some examples, such as Figure 9As shown in (a) and (b), the contact area R01 extends along the second direction. For example, the contact area R01 is a line segment extending along the second direction. For example, the shape of the contact area R01 is a straight line segment. For example, the projection of the contact area R01 onto the second direction Y is a point, that is, the projection of the contact area R01 onto the plane containing the first direction X and the third direction Z is a point. When the contact area R01 is a line segment, the contact area of the mutually coupled first coupling part 12111 and the second coupling part 12121 is smaller, which can make the movement of the first coupling part 12111 and the second coupling part 12121 along the first direction X smoother, so that the clamp 120 located in the clamping channel 1110 can be output more smoothly from the outlet 1110b. Of course, the shape of the contact area R01 is not limited in the embodiments of this disclosure, and can be designed according to requirements. For example, the shape of the contact area R01 can also be a point. For example, the shape of the contact area R01 includes at least one of a surface, a line, and a point.
[0060] In some examples, such as Figure 10 As shown, the contact area R01 extends along the first direction X and the second direction. For example, the shape of the contact area R01 is planar. For example, the shape of the contact area R01 is a rectangular planar plane. For example, the projection of the contact area R01 onto the second direction Y is a straight line segment. This makes the movement of the mutually coupled first coupling portion 12111 and the second coupling portion 12121 along the first direction X more stable. Of course, the shape of the contact area R01 is not limited in this embodiment. For example, the contact area R01 is a straight line extending along the first direction X. For example, the surface of the first coupling portion 12111 facing the second coupling portion 12121 is an arched surface, the surface of the second coupling portion 12121 facing the first coupling portion 12111 is a plane, and the contact area R01 formed by the top of the arched surface contacting the plane is a straight line.
[0061] In some examples, such as Figure 11 As shown in (a) and (b), the contact area R01 includes a plurality of discontinuous sub-contact areas R011. For example, the plurality of sub-contact areas R011 are arranged along a first direction X. For example, the shape of each sub-contact area R011 is a line segment extending along a second direction Y, and the projection of each sub-contact area R011 on the second direction Y is a point, or the shape of each sub-contact area R011 is a point. The arrangement of the plurality of sub-contact areas R011 along the first direction X can improve the stability of the arrangement of the plurality of clamps 120 in the second direction Y and the stability of their movement in the second direction Y, making the movement of the first coupling part 12111 and the second coupling part 12121 along the first direction X more stable. Each sub-contact area R011 can also make the movement of the first coupling part 12111 and the second coupling part 12121 along the first direction X smoother, thereby making the clamps 120 located in the clamping channel 1110 stably and smoothly output from the outlet 1110b.
[0062] Figures 12 to 14 This is another partial cross-sectional schematic diagram of the first end protrusion and the second end protrusion of two adjacent clips provided in an embodiment of this disclosure.
[0063] In some examples, such as Figures 12 to 14 As shown, the first end protrusion 1211 includes a first coupling portion 12111, and the second end protrusion 1212 includes a second coupling portion 12121. In two adjacent clips 120, the first coupling portion 12111 of one clip 120 is coupled to the second coupling portion 12121 of the other clip 120, and the coupled first coupling portion 12111 and the coupled second coupling portion 12121 abut against each other in the third direction Z.
[0064] In some examples, such as Figure 12 As shown, one of the mutually coupled first coupling portion 12111 and second coupling portion 12121 includes at least two sub-coupling portions, and at least a portion of the other is located between the two sub-coupling portions. The figure schematically shows that the first coupling portion 12111 includes two first sub-coupling portions 12111a. This structural design not only increases the dimensions of the first end protrusion 1211 and the second end protrusion 1212 along the first direction X, but also makes the arrangement and relative positional relationship of adjacent clips 120 along the second direction Y more stable, allowing multiple clips 120 to move more stably to the clamping channel 1110 along the second direction Y, ensuring the posture of the clips 120. Furthermore, the above structure also makes the structure of the first end protrusion 1211 and the second end protrusion 1212 more compact, improving space utilization.
[0065] In some examples, such as Figure 13 As shown, the mutually coupled first coupling portion 12111 and second coupling portion 12121 each include at least two first sub-coupling portions 12111a and at least two second sub-coupling portions 12121a, which are interlocked with each other. That is, at least a portion of the second sub-coupling portion 12121a is located between the two first sub-coupling portions 12111a, and at least a portion of the first sub-coupling portion 12111a is located between the two second sub-coupling portions 12121a. The figure schematically shows that the first coupling portion 12111 includes two first sub-coupling portions 12111a, and the second coupling portion 12121 includes two second sub-coupling portions 12121a.
[0066] In some examples, such as Figure 14As shown, in the first clip 1201 and the second clip 1202 that are adjacent along the second direction Y, the first coupling part 12111 of the first clip 1201 includes two first sub-coupling parts 12111a, and the second coupling part 12121 of the second clip 1202 includes three second sub-coupling parts 12121a. The three first sub-coupling parts 12111a and the two second sub-coupling parts 12121a are connected to each other.
[0067] Figure 15 for Figure 1 This is a schematic diagram of another structure where multiple clips are arranged along the second direction. (See diagram below.) Figure 15 As shown, the second clamping arm 122 includes a second clamping arm body 1220 and a third end protrusion 1221 and a fourth end protrusion 1222 connected to the same end of the second clamping arm body 1220. Both the third end protrusion 1221 and the fourth end protrusion 1222 protrude from the second clamping arm body 1220 in the second direction Y, and are located on opposite sides of the second clamping arm body 1220 in the second direction Y. In two adjacent clamps 120, the second clamping arm body 1220 of one clamp 120 abuts against either the third end protrusion 1221 or the fourth end protrusion 1222 of the other clamp 120. At least two clamps 120 are arranged along the second direction Y. The abutment between the end protrusions of the second clamping arms 122 of adjacent clamps and the clamping arm body further ensures the stability and compactness of the clamps 120 arranged along the second direction Y.
[0068] In some examples, such as Figure 15As shown, in two adjacent clips 120, the projection of the third end protrusion 1221 of one clip 120 onto the third direction Z at least partially coincides with the projection of the fourth end protrusion 1222 of the other clip 120 onto the third direction Z. This allows the third end protrusion 1221 and / or the fourth end protrusion 1222 to have larger dimensions in the first direction X, further increasing the contact area between the two adjacent clips 120, improving the stability of the arrangement of multiple clips 120 in the second direction Y, and enhancing the stability of movement along the second direction Y. This ensures the orientation of the clips 120 within the clip compartment 100 and guarantees the state of the clips 120 after exiting the compartment. Furthermore, due to the increase in the dimensions of the third end protrusion 1221 and / or the fourth end protrusion 1222 in the first direction X, the dimensions of the third end protrusion 1221 and / or the fourth end protrusion 1222 in the third direction Z can remain unchanged or even be reduced. This facilitates the structural design of the clamp 120 and the stacking design of multiple clamps 120, and avoids the occupancy of the clamping compartment 100 space by the dimensions of the third end protrusion 1221 and / or the fourth end protrusion 1222 in the third direction Z. Regarding the structural design of the third end protrusion 1221 and the fourth end protrusion 1222 of the second clamping arm 122, the structural design of the first end protrusion 1211 and the second end protrusion 1212 of the first clamping arm 121 in the previous embodiment can be referred to, and will not be described in detail here.
[0069] In some examples, such as Figure 15 As shown, the third end protrusion 1221 includes a third coupling portion 12211 and a third limiting portion 12212. For example, the third coupling portion 12211 of one clip 120 (e.g., the second clip 1202) at least partially overlaps with the fourth end protrusion 1222 of an adjacent clip (e.g., the third clip 1203) in the third direction Y, and the third coupling portion 12211 and the fourth end protrusion 1222 abut against each other. For example, the third limiting portion 12212 abuts against the fourth end protrusion 1222. Thus, the stability of the plurality of clips 120 arranged in the second direction Y and the stability of movement along the second direction Y are further improved, and the assembly of the plurality of clips 120 is also facilitated, guiding and ensuring that the plurality of clips 120 are assembled in place.
[0070] In some examples, such as Figure 5 and Figure 6 As shown, the clamp 120 includes a first end E1, a second end E2, and a third end E3. For example, the first clamping arm 121 and the second clamping arm 122 are rotatably connected at the first end E1. For example, as... Figures 1 to 6As shown, the first end E1 of the clamp 120 is near the inlet 1110a of the clamping channel 1110, and the second end E2 and the third end E3 of the clamp 120 are near the outlet 1110b of the clamping channel 1110. For example, the first end protrusion 1211 and the second end protrusion 1212 are located at the second end E2 of the clamp 120. For example, the third end protrusion 1221 and the fourth end protrusion 1222 are located at the third end E3 of the clamp 120. For example, the clamp 120 may also include a fifth end protrusion 123 and a sixth end protrusion 124 located at the third end E3 of the clamp 120, both of which protrude from the first clamping arm body 1210 and the second clamping arm body 1220 in the second direction Y, and the fifth end protrusion 123 and the sixth end protrusion 124 are located on both sides of the first clamping arm body 1210 and the second clamping arm body 1220 along the second direction Y. For example, the fifth end protrusion 123 and the sixth end protrusion 124 can also refer to the structure of the first end protrusion 1211 and the second end protrusion 1212 to achieve the corresponding functions. Further details will not be provided here.
[0071] This disclosure also provides a clamping pliers. Figure 16 This is a schematic diagram of the structure of one type of clamp provided in an embodiment of this disclosure. Figure 16 As shown, the clamping clamp 200 includes any of the clamping chambers 100 mentioned above, and thus, the clamping clamp 200 has the beneficial effects corresponding to the beneficial effects of the clamping chamber 100, which will not be repeated here.
[0072] Figure 17 for Figure 16 The diagram shows a cross-section of the clamping pliers before clamping. Figure 18 for Figure 17 The diagram shows a cross-section of the clamping pliers after clamping. For example, Figure 7 and Figure 8 They are respectively Figure 18 The diagram shows a partial structural schematic of the clamping forceps. (See attached diagram.) Figure 7 , Figure 8 , Figures 16 to 18As shown, the clamp 200 also includes a shaft assembly 210 and a jaw assembly 220, with a clamping magazine 100 mounted on the shaft assembly 210. The jaw assembly 220 is located at the distal end of the shaft assembly 210 and includes a first clamping arm 221 and a second clamping arm 222. The shaft assembly 210 includes a clamping mechanism 211 configured to deliver a clamp 120 located within the clamping magazine 100 to the jaw assembly 220. For example, the clamp 120 has a storage position P01 and an open position P02. When the clamp 120 is in the storage position P01, the clamp 120 is located within the clamping cavity 111. For example, when the clamp 120 is located within the clamping cavity 111, the first clamping arm 121 and the second clamping arm 122 of the clamp 120 are close to each other. When the clamp 120 is in the open position P02, it is located outside the compartment 110 and between the first clamp arm 221 and the second clamp arm 222. The first clamp arm 121 and the second clamp arm 122 of the clamp 120 are opposite to each other, and the first end protrusion 1211 and the second end protrusion 1212 of the first clamp arm 121 abut against the first clamp arm 221. Because the first end protrusion 1211 and the second end protrusion 1212 of the clamp 120 located in the clamp compartment 100 have larger dimensions, especially in the first direction X. Under the action of the clamping mechanism 211, the clamp 120 is fed from the clamping chamber 100 to the jaw assembly 220. The first end protrusion 1211 and the second end protrusion 1212 abut against the first clamp arm 221, thereby increasing the contact area between the first end protrusion 1211 and the second end protrusion 1212 and the jaw assembly 220, ensuring the stability and posture of the clamp 120 in the jaw assembly 220, and preventing the clamp 120 from twisting or shaking due to the small contact area between it and the jaw assembly 220 after it is fed to the jaw assembly 220.
[0073] In some examples, such as Figure 7 , Figure 8 , Figures 16 to 18 As shown, the first clamping arm body 1210 of the first clamping arm 121 includes an arc segment. When the clamp 120 is in the open position P02, the arc segment of the first clamping arm body 1210 bends toward the first clamping arm 221. That is, the center of curvature of the arc segment of the first clamping arm body 1210 is located on the side of the first clamping arm 221 closer to the second clamping arm 222. When the clamp 120 is in the open position P02, because the first clamping arm body 1210 bends toward the first clamping arm 221, the extension direction of the first clamping arm body 1210 is closer to the extension direction of the first clamping arm 221. The contact area between the first end protrusion 1211 and the second end protrusion 1212 protruding from the first clamping arm body 1210 in the second direction Y and the first clamping arm 221 is larger, which further ensures the stability and posture of the clamp 120 within the jaw assembly 220, and better avoids the twisting or shaking of the clamp 120.
[0074] In some examples, such as Figure 7 , Figure 8 , Figures 16 to 18 As shown, the clamping mechanism 211 delivers the clamp 120 located in the clamping chamber 100 to the jaw assembly 220, and the jaw assembly 220 can be in the open state shown in the figure. However, this embodiment of the present disclosure is not limited to this. For example, the clamping mechanism 211 delivers the clamp 120 located in the clamping chamber 100 to the jaw assembly 220, and the jaw assembly 220 can be in the closed state, that is, the first clamping arm 221 and the second clamping arm 222 are in a closed state close to each other. When the clamping mechanism 211 delivers the clamp 120 located in the clamping chamber 100 to the jaw assembly 220, the first clamping arm 121 and the second clamping arm 122 of the clamp 120 gradually open and abut against the first clamping arm 221 and the second clamping arm 222 respectively. Under the action of the first clamping arm 121 and the second clamping arm 122, the first clamping arm 221 and the second clamping arm 222 open, and correspondingly, the jaw assembly 220 is in the open state.
