Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a clamping chamber and clamping forceps. Background Technology

[0002] The clamping forceps include an operating component, a lever assembly extending from the operating component, and a jaw assembly located at the distal end of the lever assembly. The lever assembly contains a clamping chamber for holding clamps; to enable continuous clamping, multiple clamps are often placed in the chamber. During clamping, the operating component of the clamping forceps is operated to push the clamps from the chamber into the jaw assembly, and then the jaw assembly is closed, causing the clamps in the jaw assembly to clamp onto the tissue or blood vessel, thereby achieving hemostasis and ligation closure.

[0003] refer to Figure 17 In a prior art clamping magazine, clamps 1 are stacked and arranged within a clamping magazine 2, with no misalignment between the clamps 1. This clamping magazine 2 is only suitable for clamps 1 without protrusions on the clamping arms. (Reference) Figure 6 The clamp 1 in this invention includes a clamping arm with a protrusion. If... Figure 6 The clip shown is according to Figure 17 The placement method used in the clamping compartment is very space-consuming, and the clamps are difficult to place stably inside the clamping compartment.

[0004] Based on the above, it is necessary to improve the clamping mechanism in the existing technology. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the present invention aims to provide a clamping chamber and clamping clamp, which solves the technical problems of large space occupation of the clamping chamber and poor stability of the clamp placed in the clamping chamber.

[0006] This invention is achieved through the following technical solution:

[0007] A clamping magazine includes at least two clamps, each clamp having a clamping arm with a protrusion, characterized in that the clamping magazine further includes:

[0008] A clamping body having a clamping cavity to accommodate the clamps; at least two clamps are stacked in a staggered manner along a first direction such that the protrusions of adjacent clamps are staggered along the first direction; each clamp is disposed approximately along a second direction.

[0009] Furthermore, each of the clamping arms has two opposing sidewalls along the first direction, and at least one of the sidewalls has the protrusion.

[0010] Furthermore, the clamp also includes a biasing component disposed on the clamp body; the biasing component applies a force to the clamp approximately along the first direction.

[0011] Furthermore, the clamping cavity includes a first cavity and a second cavity, which are arranged sequentially along the first direction; in the initial state, both the first cavity and the second cavity contain the clamp.

[0012] Furthermore, the biasing component includes an elastic element.

[0013] Furthermore, the biasing component abuts against the first clip along the positive direction of the first direction.

[0014] Furthermore, the clamp arm has two opposing sidewalls along the first direction, and at least one of the sidewalls is provided with the protrusion. The clamp includes a first end and a second end, the protrusion being close to the first end and away from the second end. A limiting inclined surface is provided in the first cavity, and the limiting inclined surface abuts against the second end of the clamp in the first cavity.

[0015] Furthermore, the clamping arm has two opposing sidewalls along the first direction, and at least one of the sidewalls is provided with the protrusion; the second cavity has a groove extending along the second direction, and the protrusion of the clamp located in the second cavity is accommodated in the groove.

[0016] Furthermore, the clamping chamber has a first end and a second end opposite to each other along the second direction, the second cavity extends along the second direction, the second cavity forms a first opening at the first end of the clamping chamber, and the second cavity forms a second opening at the second end of the clamping chamber.

[0017] Furthermore, the clamping body includes a limiting member disposed on the side wall of the clamping body. The limiting member abuts against the clamp located in the second cavity. In response to a force applied to the clamp in the second direction, the clamp disengages from the limiting member and disengages from the second cavity from the first opening.

[0018] The present invention also provides a clamping pliers, the clamping pliers including an operating component, a shaft component and a jaw component, the shaft component extending from the operating component, the jaw component being disposed at the distal end of the shaft component, characterized in that the clamping pliers further includes the clamping chamber, the clamping chamber being disposed on the shaft component.

[0019] Furthermore, the clamping chamber is connected to the rod assembly via a snap-fit ​​structure.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: the clamping compartment of the present invention can save space by stacking the clamps in a staggered manner, so that the clamping compartment occupies a small space, and the protrusions of adjacent clamps can avoid each other, so that the clamps can be stably stacked in the clamping compartment.

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0043] It is important to understand that the terms "proximal," "posterior," "distal," and "anterior" used in this article are relative to the clinician manipulating the clamping forceps. "Proximal" and "posterior" refer to the part closer to the clinician, while "distal" and "anterior" refer to the part farther from the clinician. That is, the clamping forceps are the proximal end, and the jaw assembly is the distal end. For example, the proximal end of a component refers to the end relatively closer to the clamping forceps, and the distal end refers to the end relatively closer to the jaw assembly. However, clamps can be used in many directions and positions, so these terms expressing relative positional relationships are not limited or absolute.

[0044] In this invention, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a movable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements, such as contact. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. It should be noted that when "connected" or "linked" is preceded by a qualifier, it has the meaning defined by that qualifier, excluding only obviously excluded cases, but not other possible cases.

[0045] by Figure 1 The placement direction and angle of the middle compartment 2 are for reference. Figure 1 The middle compartment 2 is placed horizontally. The first direction is up and down (i.e., vertical), and the positive direction of the first direction is from top to bottom. The second direction is the longitudinal direction of compartment 2, i.e., left and right, which is also the horizontal direction. The third direction is perpendicular to the paper. The first, second, and third directions are perpendicular to each other. It should be noted that... Figure 1 When the placement direction and angle of the middle clamping compartment 2 are used as a reference, the third direction is perpendicular to the paper. When the placement direction and angle of the clamping compartment 2 in other attached figures change, the third direction changes with the direction and angle of the clamping compartment 2.

[0046] Please see Figure 1-4This invention provides a clamping magazine 2, which includes at least two clamps 1. The clamps 1 are common hemostatic clamps in the prior art. Each clamp 1 includes a clamp arm with a protrusion. The clamping magazine 2 includes a magazine body with a cavity to accommodate the clamps 1. At least two clamps 1 are stacked in a staggered manner along a first direction, such that the protrusions of adjacent clamps are staggered (i.e., do not overlap) along the first direction. Each clamp 1 is generally positioned along a second direction. By stacking the clamps 1, space is saved, resulting in a smaller space occupied by the clamping magazine 2. The staggered placement of the clamps 1 allows the protrusions of adjacent clamps to avoid each other, further reducing the space occupied by the clamps, and ensuring that the clamps 1 can be stably stacked within the clamping magazine 2 without tipping over.

[0047] refer to Figure 5 In this embodiment, the clamping cavity within the clamping body includes a first cavity 203 and a second cavity 204. The first cavity 203 and the second cavity 204 are arranged sequentially along a first direction, that is, the first cavity 203 is disposed above the second cavity 204. The first cavity 203 and the second cavity 204 are in communication.

[0048] refer to Figure 4 The clamping chamber 2 includes three clamps 1, which are arranged from top to bottom as clamp 101, clamp 102, and clamp 103. In the initial state, clamps 101 and 102 are located in the first cavity 203, and clamp 103 is located in the second cavity 204. The number of clamps 1 does not affect the normal use of the clamping chamber 2, and the operator can adjust the number of clamps 1 according to specific application requirements.

[0049] refer to Figure 6 The clamp 1 includes two clamping arms, namely a first clamping arm 104 and a second clamping arm 105. The first clamping arm 104 of the clamp 1 has opposing upper sidewalls 111 and lower sidewalls 112 along a first direction. The upper sidewall 111 of the first clamping arm 104 has a first protrusion 106, and the lower sidewall 112 of the first clamping arm 104 also has a first protrusion 106. The second clamping arm 105 has opposing upper sidewalls 111 and lower sidewalls 112 along the first direction. The upper sidewall 111 of the second clamping arm 105 has a second protrusion 107, and the lower sidewall 112 of the second clamping arm 105 also has a second protrusion 107. The two second protrusions 107 are connected by a protrusion 108. Specifically, the lower end of the second protrusion 107 of the upper sidewall 111 of the second clamping arm 105 is connected to the upper end of the second protrusion 107 of the lower sidewall 112 of the second clamping arm 105 by a protrusion 108. In this embodiment, the two second protrusions 107 are integral with the protrusion 108 for ease of processing. In other embodiments, the intermediate protrusion 108 may be omitted.

[0050] refer to Figure 5-7The clamping compartment 2 has opposing first ends 201 and second ends 202 along the second direction. It should be noted that the first end 201 is a region and not an endpoint, and the second end 202 is also a region and not an endpoint. The clamp 1 has opposing first ends 109 and second ends 110 along the second direction. Similarly, the first end 109 is a region and not an endpoint, and the second end 110 is a region and not an endpoint. The first end 109 of the clamp 1 is disposed near the first end 201 of the clamping compartment 2, and the second end 110 of the clamp 1 is disposed near the second end 202 of the clamping compartment 2. Each first protrusion 106 and each second protrusion 107 of the clamp 1 is located near the first end 109 and away from the second end 110 of the clamp 1. Preferably, each first protrusion 106 of the clamp 1 is located at the first end 109.

[0051] Specifically, refer to the key points. Figure 3-4 7. The stacking method of clamp 1 in clamp compartment 2 is as follows:

[0052] The first protrusion 106 and the second protrusion 107 on the lower sidewall of clip 101 both abut against the upper sidewall of clip 102, and the second protrusion 107 on the upper sidewall of clip 102 abuts against the lower sidewall of clip 101. More specifically, the first protrusion 106 on the lower sidewall of the first clamping arm 104 of clip 101 abuts against the upper sidewall of the first clamping arm 104 of clip 102, and the second protrusion 107 on the lower sidewall of the second clamping arm 105 of clip 101 abuts against the upper sidewall of the second clamping arm 105 of clip 102. The second protrusion 107 on the upper sidewall of the second clamping arm 105 of clip 102 abuts against the lower sidewall of the second clamping arm 105 of clip 101.

[0053] The first protrusion 106 and the second protrusion 107 on the lower sidewall of clip 102 both abut against the upper sidewall of clip 103, and the second protrusion 107 on the upper sidewall of clip 103 abuts against the lower sidewall of clip 102. More specifically, the first protrusion 106 on the lower sidewall of the first clamping arm 104 of clip 102 abuts against the upper sidewall of the first clamping arm 104 of clip 103, and the second protrusion 107 on the lower sidewall of the second clamping arm 105 of clip 102 abuts against the upper sidewall of the second clamping arm 105 of clip 103. The second protrusion 107 on the upper sidewall of the second clamping arm 105 of clip 103 abuts against the lower sidewall of the second clamping arm 105 of clip 102.

[0054] In summary, clips 101, 102, and 103 are stacked along the first direction, thereby saving space and reducing the space occupied by the clamping compartment 2. The first protrusion 106 of clip 102 is offset from the first protrusion 106 of clip 101, and the second protrusion 107 of clip 102 is also offset from the second protrusion 107 of clip 101. Similarly, the first protrusion 106 of clip 103 is offset from the first protrusion 106 of clip 102, and the second protrusion 107 of clip 103 is also offset from the second protrusion 107 of clip 102. Furthermore, the first protrusion 106 of clip 102 and the first protrusion 106 of clip 101 do not overlap in the first direction, and neither do the second protrusion 107 of clip 102 and the second protrusion 107 of clip 101. The first protrusion 106 of clip 103 and the first protrusion 106 of clip 102 do not overlap in the first direction, and the second protrusion 107 of clip 103 and the second protrusion 107 of clip 102 also do not overlap in the first direction, so that adjacent protrusions can avoid each other, further reducing the space occupied by clip 1, and clip 1 can be stably stacked in clip compartment 2 without tipping over.

[0055] refer to Figure 3 , 8 The clamping chamber 2 also includes a biasing component disposed in the clamping chamber body. Specifically, the biasing component is disposed in the first cavity 203 of the clamping chamber body. The biasing component can apply a force to the clamp 1 approximately in a first direction, so that the clamp 1 in the first cavity 203 can enter the second cavity 204. The aforementioned force also helps the clamp 1 to be stably clamped in the clamping chamber 2.

[0056] Specifically, the biasing assembly includes an elastic element 218 and a push plate 219. The push plate 219 abuts against the upper sidewall of the clamp 101, and the push plate 219 may be rigid or at least substantially rigid. Under the action of the elastic element 218, the push plate 219 can apply a force to the clamp 101 in a first direction. In this embodiment, the elastic element 218 is selected as a torsion spring. Specifically, the elastic element 218 includes a first torsion arm 2181, a second torsion arm 2182, and a helical body 2183. The first torsion arm 2181, the second torsion arm 2182, and the helical body 2183 are integral. Reference Figure 8 Without the action of external force, the first torsion arm 2181 and the second torsion arm 2182 of the elastic element 218 are both in a naturally extended state.

[0057] refer to Figure 3An mounting block 215 is provided within the first cavity 203 for mounting the elastic element 218. The position of the elastic element 218 does not affect its function on the clamp 1; therefore, the mounting block 215 can be positioned anywhere within the first cavity 203. However, to save space and facilitate the arrangement of the clamps 1 within the first cavity 203, the mounting block 215 is positioned near either the first end 201 or the second end 202 of the clamping chamber 2. In this embodiment, the mounting block 215 is positioned near the second end 202 of the clamping chamber 2.

[0058] The mounting block 215 has a recess 216 adapted to the spiral body 2183, and the spiral body 2183 is disposed in the recess 216. The mounting block 215 is also provided with a mounting groove 217, a first torsion arm 2181 is disposed in the mounting groove 217, and a second torsion arm 2182 is disposed on the upper side of the clamp 101 after being twisted around the spiral body 2183 at a certain angle and connected to the push plate 219, so that the elastic element 218 deforms. Thus, the second torsion arm 2182 can apply a force approximately in the first direction to the clamp 101 through the push plate 219.

[0059] refer to Figure 3-5 In this embodiment, the second cavity 204 extends through the clamping chamber body. Specifically, the second cavity 204 extends along a second direction, forming a first opening 205 at the first end 201 of the clamping chamber 2 and a second opening 206 at the second end 202 of the clamping chamber 2. In response to a force applied to the clamp 103 along the second direction, the clamp 103 disengages from the clamping chamber 2 through the first opening 205, and the biasing component pushes the clamp 101 and clamp 102 downwards, causing the clamp 102 to enter the second cavity 204. After the clamp 102 disengages from the clamping chamber 2, the biasing component pushes the clamp 101 back into the second cavity 204.

[0060] See again Figure 3-4 7. The first protrusion 106 of the clip 102 is closer to the first end 201 of the clamping chamber 2 than the first protrusion 106 of the clip 101, and the second protrusion 107 of the clip 102 is closer to the first end 201 of the clamping chamber 2 than the second protrusion 107 of the clip 101. Therefore, when the clip 102 moves toward the first end 201 of the clamping chamber 2, the first protrusion 106 and the second protrusion 107 of the clip 101 will not interfere with the movement of the clip 102.

[0061] The first protrusion 106 of clip 103 is closer to the first end 201 of clamping chamber 2 than the first protrusion 106 of clip 102. The second protrusion 107 of clip 103 is closer to the first end 201 of clamping chamber 2 than the second protrusion 107 of clip 102. Therefore, when clip 103 moves toward the first end 201 of clamping chamber 2, the first protrusion 106 and the second protrusion 107 of clip 102 will not interfere with the movement of clip 103.

[0062] For the three clamps 1 in the clamping body, their first ends 109 are not aligned along the first direction. The first end 109 of clamp 101 is furthest from the first end 201 of clamping 2, and the first end 109 of clamp 103 is closest to the first end 201 of clamping 2. Similarly, the second ends 110 of the three clamps 1 are also not aligned along the first direction. The second end 110 of clamp 101 is closest to the second end 202 of clamping 2, and the second end 110 of clamp 103 is furthest from the second end 202 of clamping 2. (Reference) Figure 3-5 A limiting inclined surface 214 is provided within the first cavity 203, and the limiting inclined surface 214 abuts against the second end 110 of the clip 1 within the first cavity 203. Thus, the limiting inclined surface 214 can support the clip 1 within the first cavity 203. Specifically, the first end 109 of the clip 101 is supported on the clip 102, specifically, the first end 109 of the clip 101 is supported on the clip 102 via the first protrusion 106 and the second protrusion 107 on its lower sidewall, and the second end 110 of the clip 101 is supported on the limiting inclined surface 214. Similarly, the first end 109 of the clip 102 is supported on the clip 103, specifically, the first end 109 of the clip 102 is supported on the clip 103 via the first protrusion 106 and the second protrusion 107 on its lower sidewall, and the second end 110 of the clip 102 is supported on the limiting inclined surface 214. In this embodiment, preferably, the limiting inclined surface 214 is disposed on the mounting block 215, thereby further saving space. At this time, the mounting block 215 is disposed adjacent to the second end 202 of the clamping compartment 2.

[0063] refer to Figure 1-2 , Figure 9 In this embodiment, the clamping body has opposing first side portions 209 and second side portions 210 along a third direction. The clamping body also has opposing third side portions 211 and fourth side portions 212 along a first direction. (See reference...) Figure 1-2 10-11, the clamping body also includes a limiting member 213, which is elastic. The limiting member 213 is disposed on the first side 209 of the clamping body and in the second cavity 204. The limiting member 213 abuts against the clamp 1 located in the second cavity 204.

[0064] Specifically, as described above, the lower end of the second protrusion 107 on the upper sidewall of the second clamping arm 105 of the clip 1 is connected to the upper end of the second protrusion 107 on the lower sidewall of the second clamping arm 105 via a protrusion 108. The limiting member 213 abuts against the protrusion 108 of the clip 1 located within the second cavity 204. In response to a force applied to the clip 1 in the second direction, the protrusion 108 of the clip 1 within the second cavity 204 disengages from the limiting member 213, and the clip 1 disengages from the second cavity 204 from the first opening 205. The limiting member 213 may also abut against the protrusion 107 of the clip 1 for limiting.

[0065] In this embodiment, by setting an offset component, the clamp 1 can be stably clamped within the clamping cavity. By setting a limiting member 213 and a limiting inclined surface 214, the clamp 1 can be further limited, making the clamp 1 more stably placed within the clamping cavity. Specifically, refer to... Figure 1-4 9-11, the limiting member 213 extends along the second direction and is recessed into the clamping cavity, so that the limiting member 213 applies a force toward the second end 202 of the clamping compartment to the protrusion 108 of the clamp 103 in a generally second direction. The second protrusion 107 of the upper sidewall of the clamp 103 abuts against the second protrusion 107 of the lower sidewall of the clamp 102 in a generally second direction. Since the second protrusion 107 of the upper sidewall of the clamp 102 abuts against the second protrusion 107 of the lower sidewall of the clamp 101 in a generally second direction, and the second end 110 of the clamp 102 abuts against the limiting inclined surface 214, the clamp 1 The second end 110 of clamp 101 also abuts against the limiting slope 214. Therefore, clamp 102 can work with limiting member 213 to limit clamp 103. At the same time, clamp 103 works with limiting slope 214 to limit clamp 102, and clamp 102 works with limiting slope 214 to limit clamp 101. Thus, clamp 101, clamp 102, and clamp 103 mutually limit each other in the second direction. Meanwhile, the first end 109 of clamp 101 is supported on clamp 102, and the second end 110 of clamp 101 is supported on limiting slope 214. The first end 109 of clamp 102 is supported on clamp 103, and the second end 110 of clamp 102 is supported on limiting slope 214. The biasing component applies a force to clamp 1 approximately in the first direction, so that clamp 1 can be stably clamped in the clamping cavity of the clamping chamber. Clip 101 can be positioned approximately along the second direction. Clip 102 can also be positioned approximately along the second direction. The second end 110 of clip 102 will not fall into the second cavity 204, thus not affecting the use of clip 103, as described below.

[0066] See again Figure 1-2 , Figure 9 To facilitate the installation of the clamp 1 inside the clamping chamber 2, this embodiment provides a first side portion 209 that can be detached from the clamping chamber body. Specifically, the first side portion 209 is detachably connected to the clamping chamber body. (See reference) Figure 10 The upper end of the first side portion 209 is provided with two snap-fit ​​members, and the lower end of the first side portion 209 is also provided with two snap-fit ​​members. Each snap-fit ​​member includes a first mounting part 2091, a second mounting part 2092, and a third mounting part 2093. (See reference) Figure 2For each snap-fit ​​member at the upper end of the first side portion 209, a first mounting portion 2091 is disposed on the outer wall of the third side portion 211, a second mounting portion 2092 is disposed on the outer wall of the second side portion 210, and a third mounting portion 2093 is embedded in the second side portion 210. For each snap-fit ​​member at the lower end of the second side portion 210, a first mounting portion 2091 is disposed on the outer wall of the fourth side portion 212, a second mounting portion 2092 is disposed on the outer wall of the second side portion 210, and a third mounting portion 2093 is embedded in the second side portion 210.

[0067] refer to Figure 5 , 9 The second cavity 204 has a groove extending along a second direction, and the protrusion of the clip 1 located in the second cavity 204 is accommodated in the groove. Specifically, the second cavity 204 has an upper wall and a lower wall opposite to each other along a first direction. The upper wall of the second cavity 204 is provided with a third opening corresponding to the first cavity 203, that is, the second cavity 204 communicates with the first cavity 203 through the third opening, so that the clip 1 in the first cavity 203 can enter the second cavity 204.

[0068] The inner wall of the upper portion of the second cavity 204 is provided with a first groove 207 and a second groove 208. The inner wall of the lower portion of the second cavity 204 is also provided with a first groove 207 and a second groove 208. The first protrusion 106 on the upper sidewall of the clip 1 is operablely located in the first groove 207 on the upper wall of the second cavity 204, and the second protrusion 107 on the upper sidewall of the clip 1 is operablely located in the second groove 208 on the upper wall of the second cavity 204. The first protrusion 106 on the lower sidewall of the clip 1 is operablely located in the first groove 207 on the lower wall of the second cavity 204, and the second protrusion 107 on the lower sidewall of the clip 1 is operablely located in the second groove 208 on the lower wall of the second cavity 204. Thus, the clip 1 can be stably placed inside the second cavity 204. Each first groove 207 and each second groove 208 penetrates the first end 201 of the clamping chamber 2, so that the clamp 1 in the second cavity 204 can stably detach from the first end 201 of the clamping chamber 2.

[0069] refer to Figure 12-14 The present invention also provides a clamping pliers, which includes an operating component 5, a rod body component 3 extending from the operating component 5, and a jaw component 4.

[0070] Operating component 5 is used to manipulate the clamping forceps. Jaw assembly 4 is located at the distal end of lever assembly 3.

[0071] The lever assembly 3 includes a spindle 301, a clamping chamber 2, a clamping rod 302, and a sleeve 303 fitted onto the spindle 301 and the clamping chamber 2. The spindle 301 has high rigidity. The jaw assembly 4 includes a first jaw arm 401 and a second jaw arm 402 that are pivotally connected to the spindle 301.

[0072] refer to Figure 12-14 The clamp 2 is located on the spindle 301. The first end 201 of the clamp 2 is positioned close to the jaw assembly 4; that is, the first end 201 of the clamp 2 is the distal end, and the second end 202 of the clamp 2 is the proximal end. (Reference) Figure 15 , 19 The spindle 301 is provided with a channel 3011, which is located between the jaw assembly 4 and the clamping chamber 2. The distal end of the channel 3011 leads to the space between the first jaw arm 401 and the second jaw arm 402, and the proximal end of the channel 3011 communicates with the first opening 205 of the second cavity 204 of the clamping chamber 2. Thus, the clamp 1 in the second cavity 204 can enter the space between the first jaw arm 401 and the second jaw arm 402 through the channel 3011, and be supported between the first jaw arm 401 and the second jaw arm 402.

[0073] refer to Figure 14 The clamping chamber 2 is connected to the main shaft 301 via a snap-fit ​​structure.

[0074] Key reference Figure 18 The clamping chamber body is provided with a first male latch 2009 and a second male latch 2010. The first male latch 2009 is located at the first end 201 of the clamping chamber 2. The second male latch 2010 is located at the second end 202 of the clamping chamber 2.

[0075] refer to Figure 19 The main shaft 301 is provided with a first female buckle 3012 and a second female buckle 3013. The first male buckle 2009, the second male buckle 2010, the first female buckle 3012 and the second female buckle 3013 constitute a buckle structure.

[0076] The first male latch 2009 is adapted to the first female latch 3012, and the first male latch 2009 and the first female latch 3012 are detachably fastened together. The second male latch 2010 is adapted to the second female latch 3012, and the second male latch 2010 and the second female latch 3013 are detachably fastened together, so that the clamping chamber 2 is detachably connected to the main shaft 301.

[0077] by Figure 13 Taking the placement angle and position of the clamp as a reference, the axis of the clamp's shaft assembly 3 is parallel to the second direction, the third direction remains perpendicular to the paper plane, and the first direction remains up and down, but the positive direction of the first direction is from bottom to top. The latching structure between the clamping chamber 2 and the main shaft 301 provides a limiting effect on the clamping chamber 2 along the second and third directions. (Referring to...) Figure 13 The sleeve 303 is fitted onto the clamping chamber 2, and the sleeve 303 provides a limiting effect on the clamping chamber 2 in the first direction, thereby enabling a stable connection between the clamping chamber 2 and the main shaft 301.

[0078] A guide groove for accommodating the feed rod 302 is provided in the spindle 301. The proximal end of the feed rod 302 is drivably connected to the operating component 5. The operating component 5 can drive the feed rod 302 to move towards the distal or proximal end of the clamp. The feed rod 302 is flexible. The proximal end of the sleeve 303 is drivably connected to the operating component 5. The operating component 5 can drive the sleeve 303 to move towards the distal or proximal end of the clamp.

[0079] The distal end of the sleeve 303 can cooperate with the jaw assembly 4. Specifically, an elastic element is provided between the first jaw arm 401 and the second jaw arm 402 to keep the jaw assembly in an open state. When the sleeve 303 moves distally, the jaw assembly 4 can be received inside the sleeve 303 from the distal end. At this time, the elastic element is compressed, and the jaw assembly 4 closes. When the sleeve 303 moves proximally, the jaw assembly 4 can extend from the distal end of the sleeve 303, and the elastic element releases energy to open the jaw assembly 4. Figure 14 As shown, the elastic element can be spring 403. (Reference) Figure 20 In an optional embodiment, the clamp has a rotating joint 7. Specifically, the main shaft 301 includes a first shaft portion 3014 and a second shaft portion 3015. The second shaft portion 3015 extends from the operating assembly 5. The first shaft portion 3014 is disposed at the distal end of the second shaft portion 3015. The proximal end of the first shaft portion 3014 is connected to the distal end of the second shaft portion 3015 via the rotating joint 7, allowing the first shaft portion 3014 to rotate relative to the second shaft portion 3015. The jaw assembly 4 is connected to the distal end of the first shaft portion 3014, allowing the jaw assembly 4 to rotate relative to the second shaft portion 3015 under the influence of the first shaft portion 3014, facilitating the physician to adjust the position and angle of the jaw assembly 4. In this embodiment, the clamp 2 is disposed on the first shaft portion 3014, and the clamp 2 is connected to the first shaft portion 3014 via a snap-fit ​​structure, allowing the clamp 2 to rotate together with the jaw assembly 4. To accommodate the rotation of the first shaft portion 3014, in this embodiment, the sleeve 303 is divided into a first tube body 3031 and a second tube body 3032. The first tube body 3031 is fitted onto the first shaft portion 3014 and the clamping chamber 2. The second tube body 3032 is fitted onto the second shaft portion 3015. The first tube body 3031 and the second tube body 3032 are connected by two pivoting members 6. The proximal end of each pivoting member 6 is pivotally connected to the second tube body 3032, and the distal end of each pivoting member 6 is pivotally connected to the first tube body 3031. Thus, when the first shaft portion 3014 rotates, the first shaft portion 3014 drives the first tube body 3031 to rotate, allowing the first tube body 3031 to rotate relative to the second tube body 3032. The clamping process of the clamping clamp in this embodiment of the invention is described below.

[0080] In the initial state (i.e., when the clamping rod 302 is not clamping), whether the distal end of the clamping rod 302 extends into the second cavity 204 or not, neither structure will affect the normal use of the clamping forceps. If the distal end of the clamping rod 302 does not extend into the second cavity 204 in the initial state, when the clamping rod 302 moves towards the distal end of the clamping forceps, the distal end of the clamping rod 302 can extend into the second cavity 204 from the second opening 206.

[0081] refer to Figure 15 In this embodiment, the distal end of the feeding rod 302 extends into the second cavity 204 in the initial state, that is, the distal end of the feeding rod 302 is initially positioned in the second cavity 204. As mentioned above, the clamping chamber 2 includes three clamps 1, which are clamp 101, clamp 102 and clamp 103 from top to bottom.

[0082] refer to Figure 16 The operating component 5 is manipulated to drive the clamping lever 302 to move towards the distal end (i.e., forward) of the clamping jaws, causing the distal end of the clamping lever 302 to abut against the second end 110 of the clamp 103 in the second cavity 204 and push the clamp 103 to move in the second direction. This causes the clamp 103 to disengage from the limiting member 213 and exit the second cavity 204 through the first opening 205 before entering the jaw assembly 4. At this time, the clamping lever 302 still pushes against the clamp 103 at the second end 110 to prevent the clamp 103 from moving towards the proximal end and failing to clamp. Furthermore, due to the holding action of the clamping lever 302, the clamps 101 and 102 will not move towards the second cavity 204 under the action of the biasing component.

[0083] After the clamp 103 enters the jaw assembly 4, the operating component 5 is manipulated. The operating component 5 drives the sleeve 303 to move towards the distal end of the clamping forceps, the jaw assembly 4 closes, and the clamp 103 in the jaw assembly 4 is clamped to the object (tissue or blood vessel).

[0084] After the jaw assembly 4 is closed, the operating component 5 is manipulated. The operating component 5 drives the sleeve 303 to move towards the proximal end of the clamp (i.e., backward), the jaw assembly 4 opens, and the clamp 103 disengages from the jaw assembly 4.

[0085] After clamp 103 disengages from jaw assembly 4, the operating component 5 is manipulated. Operating component 5 drives the clamping rod 302 to move proximally towards the clamping end, causing the clamping rod 302 to return to its reset position. Once the clamping rod 302 returns to its reset position, under the action of the biasing component, the second end 110 of clamp 101 in the first cavity 203 moves along the limiting inclined surface 214, and the second end 110 of clamp 102 also moves along the limiting inclined surface 214. Both clamp 101 and clamp 102 have downward and forward displacements, and clamp 102 moves into the second cavity 204. Following the above clamping process for clamp 101, clamp 102 is clamped. After clamp 102 disengages from jaw assembly 4, under the action of the biasing component, clamp 101 in the first cavity 203 moves into the second cavity 204, and the clamping operation on clamp 101 continues.

[0086] As mentioned earlier, in this embodiment, the second ends 110 of the three clamps 1 in the clamping chamber body are not aligned. The second end 110 of clamp 101 is closest to the second end 202 of clamping chamber 2, and the second end 110 of clamp 103 is furthest from the second end 202 of clamping chamber 2. If the limiting slope 214 is not provided, in the initial state, i.e., when not clamping, the second end 110 of clamp 102 will fall into the second cavity 204 and block the second end 110 of clamp 103. As a result, when the clamping rod 302 moves towards the proximal end, it will push against the second end 110 of clamp 102, but cannot push against the second end 110 of clamp 103, thus the clamping pliers cannot be used normally. Similarly, when clamping clamp 102, the second end 110 of clamp 101 will fall into the second cavity 204, and the clamping rod 302 cannot push against clamp 102. In this embodiment, a limiting inclined surface 214 is provided in the first cavity 203. The limiting inclined surface 214 can support the clamp 1 in the first cavity 203, and the clamp 101 and clamp 102 can be arranged generally along the second direction. The second end 110 of the clamp 102 will not fall into the second cavity 204, thus not affecting the use of the clamp 103. Similarly, when clamping the clamp 102, the second end 110 of the clamp 101 will not fall into the second cavity 204, and the clamping rod 302 can push the clamp 102 into the jaw assembly 4.

[0087] In summary, in this embodiment, by stacking the clips 1 in a staggered manner, space can be saved, and the protrusions of adjacent clips 1 can avoid each other, so that the clips 1 can be stably stacked in the clip compartment 2.
