DETAILED DESCRIPTION

[0041] In order to better explain the present application, so as to be understood, the present application is described in detail below by means of specific embodiments, with reference to the accompanying drawings. In the description of the present application, "distal" refers to the side close to the patient, and "proximal" refers to the side close to the operator; in the description of the present application, "circumferential" refers to the direction perpendicular to the axis of the clip magazine assembly and the adapter.

[0042] Embodiment 1

[0043] As shown in Figures 1 to 4 , the present embodiment provides a clip applier, which comprises a clip magazine assembly 1 and an adapter 8.

[0044] As shown in Figure 1 and Figure 2 , the clip magazine assembly 1 comprises a swivel-shaped proximal end 2, a shaft (a part of which is shown) and an end effector (not shown). In the swivel-shaped proximal end 2, "swivel-shaped" refers to the cross-sectional shape of the outer contour of the side wall of the proximal end being circular, and does not strictly limit the proximal end to be a constant-diameter cylinder, nor does it limit the interior of the proximal end to be a swivel body.

[0045] In the present embodiment, the swivel-shaped proximal end 2 comprises two parts connected together in relative rotation, namely a clip magazine-side fixed portion 11 and a clip magazine-side rotating portion 12, the clip magazine-side fixed portion 11 is located at the proximal end of the clip magazine-side rotating portion 12, and the proximal end of the clip magazine-side fixed portion 11 is provided with an identification signal generating structure for establishing communication with an identification signal receiver fixedly arranged in the adapter 8.

[0046] The outer contour of the side wall of the clip magazine-side fixed portion 11 and the clip magazine-side rotating portion 12 is swivel-shaped, so the outer contour of the side wall of the swivel-shaped proximal end 2 formed by the combination of the two is swivel-shaped. The clip magazine-side fixed portion 11 and the clip magazine-side rotating portion 12 are provided with a communicating accommodation cavity inside for accommodating the proximal end of the shaft. Preferably, the clip magazine-side fixed portion 11 and the clip magazine-side rotating portion 12 each comprise two housings that are symmetrically spliced and fixed by clamping, so as to facilitate the installation and disassembly between the clip magazine-side fixed portion 11 and the clip magazine-side rotating portion 12.

[0047] The adapter 8 comprises an adapter-side fixed part 9 and an adapter-side rotating part 10. The adapter-side fixed part 9 is a part that does not rotate during the operation of the clip applier. The adapter-side rotating part 10 is rotatably connected to the adapter-side fixed part 9 and protrudes more distally relative to the adapter-side fixed part 9.

[0048] The adapter-side fixed part 9 is selectively lockingly connected to the clip-cartridge-side fixed part 11. The identification signal receiver is arranged on the adapter-side fixed part 9, so that the adapter-side fixed part 9 and the clip-cartridge-side fixed part 11 can ensure stable transmission of signals after being connected.

[0049] The adapter-side rotating part 10 is selectively lockingly connected to the clip-cartridge-side rotating part 12 to drive the clip-cartridge-side rotating part 12 to rotate.

[0050] The adapter-side fixed part 9 and the adapter-side rotating part 10 each have a rotationally-shaped channel 3 for inserting the rotationally-shaped proximal end 2. The rotationally-shaped channels 3 of the adapter-side fixed part 9 and the adapter-side rotating part 10 are arranged in a direction from proximal to distal and axially communicate with each other. The "rotationally-shaped" in the rotationally-shaped channel 3 means that the inner wall of the channel is circular in cross-sectional shape, and is not strictly limited to a cylindrical body with equal diameters. It can be understood that the inner wall of the rotationally-shaped channel 3 and the outer wall of the rotationally-shaped proximal end 2 are arranged in a rotationally-shaped manner because they need to be inserted while rotating.

[0051] The clip-cartridge-side rotating part 12 is partially inserted into the rotationally-shaped channel 3 of the adapter-side rotating part 10. The exposed part of the clip-cartridge-side rotating part 12 serves as a visible surface. The visible surface of the clip-cartridge-side rotating part 12 is arc-shaped in accordance with an ergonomic structure, which facilitates grasping and installation of the clip-cartridge assembly 1. Preferably, the edge of the visible surface of the clip-cartridge-side rotating part 12 is arc-shaped.

[0052] The connection position of the adapter-side fixed part 9 and the adapter-side rotating part 10 forms a stepped surface, which constitutes the distal end surface of the rotationally-shaped channel 3 of the adapter-side fixed part 9. A first insertion slot (not shown in the figure) is arranged on the distal end surface. The distal end of the adapter-side rotating part 10 faces outward, forming the distal end surface of the rotationally-shaped channel 3 of the adapter-side rotating part 10. A second insertion slot (not shown in the figure) is arranged on the distal end surface. The first insertion slot and the second insertion slot are each formed in a slot shape by the extension of the respective distal end surface toward the proximal end direction. It can be understood that the first insertion slot and the second insertion slot are both adapter-side insertion parts 5. Preferably, the first insertion slot and the second insertion slot are circumferentially aligned.

[0053] A first insertion part (see FIG. 2) is arranged on the proximal end outer wall of the clip-cartridge-side fixed part 11. Figure 2The two labels "6") in the middle and upper layers are provided with second insertion parts (see Figure 2 The first insertion part is inserted into the first insertion slot, and the adapter-side fixed part 9 and the clamp-cartridge-side fixed part 11 are circumferentially locked, i.e., they cannot rotate relative to each other. The second insertion part is inserted into the second insertion slot, and the adapter-side rotating part 10 and the clamp-cartridge-side rotating part 12 are circumferentially locked, i.e., they cannot rotate relative to each other.

[0054] Further, to facilitate the insertion of the first insertion slot and the first insertion part, the distal end surface of the adapter-side fixed part 9 is provided with a first guide part (not shown in the figure), which is used to cooperate with the first insertion part of the clamp-cartridge assembly 1 during the insertion of the rotating proximal end 2 in one or two directions towards the rotating channel 3, and to automatically guide the clamp-cartridge-side fixed part 11, thereby guiding the insertion of the first insertion part into the first insertion slot. Similarly, the corresponding first insertion part is used to cooperate with the first guide part during the insertion of the clamp-cartridge-side fixed part 11 in one or two directions towards the rotating channel 3, thereby guiding the insertion of the first insertion part into the first insertion slot.

[0055] Specifically, the first guide part includes two first arc-shaped guide slots provided on the distal end surface of the rotating channel 3 of the adapter-side fixed part 9, which are symmetrically arranged on both sides of the first insertion slot. The first arc-shaped guide slots extend circumferentially from a position on the distal end surface of the rotating channel 3 and gradually increase in depth during the extension to connect the first insertion slot. Thus, as the clamp-cartridge-side fixed part 11 is inserted while rotating, the first arc-shaped guide slots guide the first insertion part (see the label "6" in the figure) of the clamp-cartridge-side fixed part 11 that needs to be inserted into the first insertion slot to the first insertion slot, i.e., the two first arc-shaped guide slots gradually increase in depth towards the first insertion slot between them. This allows the clamp-cartridge-side fixed part 11 to be inserted in any direction, i.e., bidirectional automatic guidance is achieved, and bidirectional blind assembly is further achieved. Of course, to simplify the structure, only one arc-shaped guide slot can be provided for one insertion slot, in which case the operator needs to be informed of the rotation direction when inserting the clamp-cartridge assembly into the adapter, and automatic guidance can only be achieved when rotating in that direction.

[0056] In the present embodiment, a plurality of first insertion slots are provided, which are uniformly arranged along the circumference of the rotating channel 3. A plurality of first guide parts are correspondingly provided, which are arranged along the circumference. One first insertion slot and the two first arc-shaped guide slots on both sides thereof form a group, and multiple groups are the same and uniformly arranged along the circumference. This saves installation space and facilitates installation. Preferably, two first insertion slots are provided, so that a maximum rotation of 90° can achieve successful insertion.

[0057] Correspondingly, when the plurality of first insertion slots are arranged uniformly in the circumferential direction, the plurality of first insertion portions are also arranged uniformly in the circumferential direction, preferably two first insertion portions. The first insertion portion is a protrusion protruding from the side wall of the clamping compartment side fixed part 11, which is fixedly connected with the rotary proximal end 2, for example, integrally formed, and the proximal end of the protrusion is tapered to form a triangle, an arc or a trapezoid, which is conducive to smooth and convenient guidance. In this embodiment, the distal end and the proximal end of the protrusion are both triangular, and the middle is rectangular, forming a double arrow shape. In this way, the tapered proximal end of the protrusion walks on the first arc-shaped guide slot as the clamping compartment assembly 1 rotates until it reaches the first insertion slot and is inserted into the first insertion slot. Since there can be other structures between the clamping compartment side fixed part 11 and the adapter side fixed part 9 that can provide circumferential locking function (for example, a positioning hole can be provided on the inner wall of the rotary channel 3 of the adapter side fixed part 9, and a spring buckle and an elastic ring are provided in the clamping compartment side fixed part 11), the size of the first insertion portion can be smaller.

[0058] Similarly, in order to facilitate the insertion of the second insertion slot (see reference numeral "5" in the figure) and the second insertion portion (see reference numeral "6" in the figure), Figure 2 which is located in the lower layer), the distal end surface of the rotary channel 3 of the adapter side rotating part 10 is provided with a second guidance part (see reference numeral "4" in the figure), which is used to cooperate with the second insertion portion of the clamping compartment assembly 1 during the insertion of the clamping compartment side rotating part 12 in one or two directions towards the rotary channel 3, to automatically guide the clamping compartment side rotating part 12, and guide the second insertion portion to be inserted into the second insertion slot; the second insertion portion is matched to cooperate with the second guidance part during the insertion of the rotary proximal end 2 in one or two directions towards the rotary channel 3, to guide the second insertion portion to be inserted into the second insertion slot.

[0059] Specifically, the second guidance part is arranged on the distal end surface of the rotary channel 3 of the adapter side rotating part 10, and the second guidance part includes two second arc-shaped guide slots, which are symmetrically arranged on both sides of the second insertion slot. The second arc-shaped guide slot extends in the circumferential direction from a certain position of the distal end surface of the adapter side rotating part 10 and gradually increases in depth during the extension until it connects the second insertion slot. Thus, as the clamping compartment assembly 1 is inserted while rotating, the second arc-shaped guide slot guides the second insertion portion of the clamping compartment assembly 1 that needs to be inserted into the second insertion slot to the second insertion slot. Because both second arc-shaped guide slots gradually increase in depth towards the second insertion slot between them, the direction of the insertion of the clamping compartment side rotating part 12 is not limited, and bidirectional automatic guidance is achieved. Of course, in order to simplify the structure, only one arc-shaped guide slot can be arranged for one insertion slot, in which case the operator needs to be informed of the rotation direction when rotating the clamping compartment assembly into the adapter, and automatic guidance can only be achieved when rotating in that direction.

[0060] In the embodiment, a plurality of second slots are arranged, and the plurality of second slots are arranged uniformly along the circumference. A plurality of second guiding portions are correspondingly arranged, and the plurality of second guiding portions are arranged along the circumference. One second slot and two second arc-shaped guiding slots on both sides of the second slot are taken as a group, and the plurality of groups are the same and are arranged uniformly along the circumference. In this way, the installation stroke is saved, and the installation is easy. Preferably, two second slots are arranged, so that the first plug-in part can be inserted successfully by rotating at most 90°.

[0061] Correspondingly, when the plurality of second slots are arranged uniformly along the circumference, the plurality of second plug-in parts are also arranged uniformly along the circumference of the rotationally-shaped proximal end 2, and two second plug-in parts are arranged in the embodiment. In the embodiment, the second plug-in part is a protrusion protruding from the side wall of the clamping-warehouse-side rotating part 12, and the proximal end of the protrusion is tapered to form a triangle, an arc or a trapezoid. Such a design is beneficial to smooth and convenient guiding. In the embodiment, the proximal end of the protrusion is a triangle, and the rest is a rectangle, forming a single arrow shape. In this way, the tapered proximal end of the protrusion walks on the second arc-shaped guiding slot along with the rotation of the clamping-warehouse-side rotating part 12, until it walks to the second slot and is inserted into the second slot.

[0062] It can be understood that at this time, the structure for guiding is arranged in the adapter 8, and therefore the first guiding portion and the second guiding portion are both adapter-side guiding portions 4.

[0063] The reason for separately arranging the two plug-in parts and the two guiding portions is that the clamping-warehouse-side rotating part 12 and the clamping-warehouse-side fixed part 11 are relatively rotatable when the clamping-warehouse assembly 1 is inserted, so that the guiding is performed separately.

[0064] The reason why the first plug-in part forms a double arrow shape and the second plug-in part forms a single arrow shape is that when the clamping-warehouse assembly 1 is pulled out, the distal end side arrow of the first plug-in part first performs a guiding function, and since the clamping-warehouse-side fixed part 11 and the clamping-warehouse-side rotating part 12 are relatively fixed at this time, the guiding of the first plug-in part also makes the clamping-warehouse-side fixed part 11 and the clamping-warehouse-side rotating part 12 obtain the guiding when pulled out. Of course, if the rotationally-shaped proximal end 2 of the clamping-warehouse assembly 1 is a whole rotation, then one plug-in part can be used in the axial direction.

[0065] Since the protrusion as the first plug-in part and the protrusion as the second plug-in part are both arranged on the outer surface of the corresponding part, the radial dimension of the clamping-warehouse-side rotating part 12 is smaller than the radial dimension of the clamping-warehouse-side fixed part 11, so that the first plug-in part can be inserted into the adapter-side fixed part 9 through the rotationally-shaped channel 3 of the adapter-side rotating part 10, or the first slot and the second slot are circumferentially aligned to allow the first plug-in part to pass through the second slot and then pass through the first slot.

[0066] Of course, the present application is not limited to this, the protrusion as the first plug-in part and the protrusion as the second plug-in part can also be arranged to protrude from the proximal end face of the corresponding part. No matter where the first plug-in part and the second plug-in part are located, the first slot and the second slot can be a bottomed groove or a non-bottomed groove. When the former, the first plug-in part and the second plug-in part abut to the groove bottom to be in place; when the latter, a special in-place structure is arranged in the adapter 8.

[0067] In addition, the shape of the protrusion can not be limited to the above-mentioned single arrow or double arrow shape, and the protrusion can also be a rod body with a tapered or circular arc-shaped proximal end.

[0068] In addition, since the clipper side rotating part 12 and the clipper side fixed part 11 are rotatable, the clipper side fixed part 11 needs to be held by hand first to rotate and find the position, so the axial distance between the first plug-in part and the second plug-in part needs to be greater than the axial distance between the first slot and the second slot.

[0069] In the present embodiment, the adapter side fixed part 9 and the clipper side fixed part 11 can be simultaneously circumferentially locked by using other locking mechanisms (for example, the cooperation between the elastic buckle and the lock hole), and the adapter side rotating part 10 and the clipper side rotating part 12 only use the plug-in of the second slot and the second plug-in part to bear the selectable circumferential locking function between them, that is, the adapter side rotating part 10 and the clipper side rotating part 12 are selectable locked together, and when rotating together, the adapter side rotating part 10 and the clipper side rotating part 12 do not separate. Therefore, it can be obviously seen that the size of the second plug-in part is greater than that of the first plug-in part, and at the same time, the width of the second slot is greater than that of the first slot, so as to obtain a stable circumferential locking function.

[0070] Of course, in other embodiments, a circumferential locking assembly that mainly realizes the circumferential locking function can also be arranged between the adapter side rotating part 10 and the clipper side rotating part 12 (for example, a positioning hole can be arranged on the inner wall of the adapter side rotating part 10 of the rotating channel 3, and an elastic buckle and an elastic ring are arranged in the clipper side rotating part 12 of the clipper assembly 1).

[0071] On the contrary, it can be understood that if the size of the first plug-in part is large enough and the working condition allows, the cooperation of the first plug-in part and the first slot can replace the locking mechanism to realize the selectable locking between the adapter side fixed part 9 and the clipper side fixed part 11.

[0072] In the present embodiment, referring to Figure 4The identification signal generating structure is an identification information storage chip, and the identification information storage chip stores the specification information of the clip cartridge assembly 1, wherein the specification information includes the information of the clips in the clip cartridge assembly 1. The identification information storage chip is provided with a plurality of groups of pin needles 13 in communication with the identification signal receiver, and when any group of pin needles is in communication with the identification signal receiver, communication connection can be realized, without the need of making the specified pin needles 13 in communication with the identification signal receiver, so that the communication connection between the clip cartridge assembly 1 and the adapter 8 is more convenient and the reverse installation of the clip cartridge assembly 1 is allowed. When the plug-in part is plugged into the slot, a group of pin needles is necessarily connected with the identification signal receiver. In the embodiment, two groups of pin needles are provided, each group of pin needles includes four pin needles 13, but one or more pin needles 13 in each group of pin needles are also possible variations. Preferably, the plurality of groups of pin needles are uniformly arranged in the circumferential direction, and in the embodiment, the two groups of pin needles are arranged at an angle of 180°. In the embodiment, the double pin arrangement can realize blind installation, and the clip cartridge assembly 1 can be installed in both directions, thereby saving installation stroke and facilitating installation.

[0073] The installation steps of the clip cartridge assembly 1 and the applicator in the embodiment are described as follows:

[0074] S1, the clip cartridge assembly 1 is inserted into the adapter 8 as a whole, and when the first plug-in part abuts against the distal end of the rotary channel 3 of the adapter side fixed part 9 during the insertion process, the operator will have a sense of being in place, and the operator inserts the clip cartridge side fixed part 11 towards the proximal direction while rotating, and the first arc-shaped guide groove guides the first plug-in part into the first slot;

[0075] S2, the operator inserts the clip cartridge side rotating part 12 towards the proximal direction while rotating, and the second arc-shaped guide groove guides the second plug-in part into the second slot, and in this process, the clip cartridge side rotating part 12 pushes the clip cartridge side fixed part 11 to continue the linear movement towards the proximal direction along the first slot, and then the clip cartridge side rotating part 12 is pushed towards the proximal direction until one of the first plug-in part and the second plug-in part is inserted in place. At this time, the clip cartridge side fixed part 11 and the adapter side fixed part 9 are locked, the clip cartridge side rotating part 12 and the adapter side rotating part 10 are locked, and the communication connection between the clip cartridge assembly 1 and the adapter 8 is established.

[0076] When the clip applier works, the clip cartridge side fixed part 11 can be fixed in the adapter 8 in a manner of keeping relative static with the adapter side fixed part 9. The rod body of the clip cartridge assembly 1 is partially fixed in the accommodating cavity of the clip cartridge housing 1 in a manner of rotating with the clip cartridge side rotating part 12 along the axis of the rod body, and the rod body is provided with clips to be applied. One end of the end effector of the clip cartridge assembly 1, i.e., the connecting end, is connected with the rod body, and in the actual application process, the end effector is a pair of pincers for applying the clips.

[0077] In this embodiment, by setting the relatively rotating clamping compartment side fixed part 11 and the clamping compartment side rotating part 12, when the clamping compartment assembly 1 is working, the identification signal generating structure in the clamping compartment side fixed part 11 can be relatively stationary to the adapter side fixed part 9 of the adapter 8, which ensures the reliability of the signal transmission between the clamping compartment assembly 1 and the adapter 8, and further ensures the reliability of the identification in the adapter 8.

[0078] Embodiment 2

[0079] With reference to Figure 5 In this embodiment, the difference from embodiment 1 is that the protrusion is changed to a plug (see Figure 5 No. 6 in the figure), which is elastically connected to the side wall of the rotary proximal end 2, and the deformation direction of the elastic connection is the axis direction of the rotary proximal end 2. Here, taking the example that the plug is connected to the rotary proximal end 2 by an elastic member and a fixed member, the distal end of the plug is connected to the proximal end of the elastic member, the distal end of the elastic member is connected to the proximal end of the fixed member, and the fixed member is connected to the rotary proximal end 2. In this way, when the plug moves on the guide groove, the elastic member of the plug is compressed, and when it moves to the insertion slot, the elastic member drives the plug to pop into the insertion slot, thereby preventing the situation of missing the insertion slot due to too fast rotation. The proximal end of the plug is tapered to form a triangle, an arc or a trapezoid, the overall shape of the plug can be a plate shape or a rod shape, and the elastic force of the elastic member is relatively small, which ensures that the plug can basically only move in the proximal-distal direction and not be bent. The distal end of the fixed member to which the plug of the clamping compartment side fixed part is connected is tapered to form a triangle, an arc or a trapezoid; the distal end of the fixed member to which the plug of the clamping compartment side rotating part is connected does not need to be tapered.

[0080] Among them, the elastic member can adopt a spring (preferably a compression spring), a sponge.

[0081] Embodiment 3

[0082] With reference to Figure 6 and Figure 7 The main difference between this embodiment and embodiment 1 is that the guide part is arranged in the clamping compartment assembly 1 to form the clamping compartment side guide part 7. The relevant differences are described in detail as follows, and the same parts as embodiment 1 are not described again.

[0083] The protrusion from the inner wall of the rotary channel 3 of the adapter side fixed part 9 to the outside of the distal end of the rotary channel 3 is a protrusion as the first insertion part, also as the adapter side insertion part 5. Meanwhile, the protrusion from the inner wall of the rotary channel 3 of the adapter side rotating part 10 to the outside of the distal end of the rotary channel 3 is a protrusion as the second insertion part, also as the adapter side insertion part 5. The distal end of the protrusion as the first insertion part protrudes to the outside of the distal end of the rotary channel 3, and the distal end and the proximal end of the protrusion are tapered to form a triangle, an arc or a trapezoid, which is beneficial for smooth and convenient guiding. In the embodiment, the distal end and the proximal end of the protrusion are triangles, and the middle part is a rectangle, forming a double arrow shape. Since there can be other structures that can provide circumferential locking function between the cartridge side fixed part 11 and the adapter side fixed part 9 (for example, a positioning hole can be arranged on the inner wall of the rotary channel 3 of the adapter side fixed part 9, and a spring buckle and an elastic ring can be arranged on the cartridge side fixed part of the cartridge assembly 1), the size of the first insertion part can be smaller. The distal end of the protrusion as the second insertion part protrudes to the outside of the distal end of the rotary channel 3 where the protrusion is located, and the distal end of the protrusion is tapered to form a triangle, an arc or a trapezoid, which is beneficial for smooth and convenient guiding. In the embodiment, the distal end of the protrusion is a triangle, and the rest is a rectangle, forming a single arrow shape.

[0084] Correspondingly, in the cartridge assembly 1, the cartridge side fixed part 11 of the rotary proximal end 2 is provided with a first guiding part (see the label "7" in the upper middle layer) and a first insertion slot (see the label "6" in the upper middle layer), and the cartridge side rotating part 12 of the rotary proximal end 2 is provided with a second guiding part (see the label "7" in the lower middle layer) and a second insertion slot (see the label "6" in the lower middle layer), so that the cartridge side fixed part 11 and the cartridge side rotating part 12 of the rotary proximal end 2 are both provided with a cartridge side insertion part 6 and a cartridge side guiding part 7. Figure 6 Figure 6 Correspondingly, in the cartridge assembly 1, the cartridge side fixed part 11 of the rotary proximal end 2 is provided with a first guiding part (see the label "7" in the upper middle layer) and a first insertion slot (see the label "6" in the upper middle layer), and the cartridge side rotating part 12 of the rotary proximal end 2 is provided with a second guiding part (see the label "7" in the lower middle layer) and a second insertion slot (see the label "6" in the lower middle layer), so that the cartridge side fixed part 11 and the cartridge side rotating part 12 of the rotary proximal end 2 are both provided with a cartridge side insertion part 6 and a cartridge side guiding part 7. Figure 6 Figure 6 Correspondingly, in the cartridge assembly 1, the cartridge side fixed part 11 of the rotary proximal end 2 is provided with a first guiding part (see the label "7" in the upper middle layer) and a first insertion slot (see the label "6" in the upper middle layer), and the cartridge side rotating part 12 of the rotary proximal end 2 is provided with a second guiding part (see the label "7" in the lower middle layer) and a second insertion slot (see the label "6" in the lower middle layer), so that the cartridge side fixed part 11 and the cartridge side rotating part 12 of the rotary proximal end 2 are both provided with a cartridge side insertion part 6 and a cartridge side guiding part 7.

[0085] Specifically, the proximal end of the cartridge side fixed part 11 faces the proximal side, and the first insertion slot is arranged on the proximal end. The connection position of the cartridge side fixed part 11 and the cartridge side rotating part 12 forms a stepped surface, which constitutes the proximal end surface of the cartridge side rotating part 12, and the second insertion slot is arranged on the proximal end surface. The first insertion slot and the second insertion slot are on the outer walls of the cartridge side fixed part 11 and the cartridge side rotating part 12, and are both formed in a groove shape by the extension of the respective proximal end surfaces towards the distal direction, and are open outwardly through the outer walls. It can be understood that the first insertion slot and the second insertion slot are the cartridge side insertion part 6.

[0086] ​​When the first plug-in part is inserted into the first slot, the adapter side fixed part 9 and the clipper side fixed part 11 form an alternative circumferential locking, i.e. they cannot rotate relative to each other; when the second plug-in part is inserted into the second slot, the adapter side rotating part 10 and the clipper side rotating part 12 form an alternative circumferential locking, i.e. they cannot rotate relative to each other.

[0087] In order to facilitate the insertion of the first plug-in part into the first slot, the first guide part is used to cooperate with the first plug-in part during the process of rotating insertion of the swivel-shaped proximal end 2 towards the swivel-shaped channel 3 in one or two directions, and constitutes an automatic guide for the clipper side fixed part 11, guiding the insertion of the first plug-in part into the first slot; the first plug-in part is used to cooperate with the first guide part during the process of rotating insertion of the clipper side fixed part 11 towards the swivel-shaped channel 3 in one or two directions, guiding the insertion of the first plug-in part into the first slot. Specifically, the tapered distal end of the protrusion walks on the first arc-shaped guide groove with the rotation of the clipper assembly 1 until it is inserted into the first slot. In this way, the tapered distal end of the protrusion walks on the second arc-shaped guide groove with the rotation of the clipper assembly 1 until it is inserted into the second slot.

[0088] It can be understood that at this time, the structure for guiding is arranged in the adapter 8, so the first guide part and the second guide part are both clipper side guide parts 7.

[0089] Further, the first guide part includes two first arc-shaped guide grooves arranged on the proximal end face of the clipper side fixed part 11, and the two first arc-shaped guide grooves are symmetrically arranged on both sides of the first slot. The first arc-shaped guide groove extends from a position on the proximal end face of the clipper side fixed part 11 and gradually increases in depth during the extension process to connect the first slot. Thus, with the rotation and insertion of the clipper side fixed part 11, the first arc-shaped guide groove guides the first plug-in part in the adapter side fixed part 9 that needs to be inserted into the first slot to the first slot, i.e. the two first arc-shaped guide grooves gradually increase in depth towards the first slot between them. This allows the direction of the rotation and insertion of the clipper side fixed part 11 to be unrestricted, i.e. bidirectional automatic guiding is achieved, and further blind assembly is achieved. Of course, in order to simplify the structure, only one arc-shaped guide groove can be arranged for one slot, and at this time the operator needs to be informed of the rotation direction when rotating and inserting the clipper assembly into the adapter. Automatic guiding can only be achieved when rotating in this direction.

[0090] In the present embodiment, a plurality of first slots are arranged, and the plurality of first slots are uniformly arranged along the circumference. A plurality of first guide parts are correspondingly arranged, and the plurality of first guide parts are arranged along the circumference. One first slot and the two first arc-shaped guide grooves on both sides thereof form a group, and the plurality of groups are the same and are uniformly arranged along the circumference. In this way, the installation stroke is saved and the installation is easy. Preferably, two first slots are arranged, so that a maximum rotation of 90° can be achieved for successful insertion.

[0091] Similarly, in order to facilitate the insertion of the second slot and the second insertion part, a second guide part is arranged on the proximal end surface of the cartridge side rotating part 12, and the second guide part is used to cooperate with the second insertion part of the adapter during the rotation insertion of the cartridge side rotating part 12 along one or two directions towards the rotation channel 3 of the adapter side rotating part 10, so as to automatically guide the cartridge side rotating part 12 and guide the second insertion part to be inserted into the second slot; and the matched second insertion part is used to cooperate with the second guide part during the rotation insertion of the rotation proximal end 2 along one or two directions towards the rotation channel 3, so as to guide the second insertion part to be inserted into the second slot.

[0092] Specifically, the second guide part is arranged on the proximal end surface of the cartridge side rotating part, and the second guide part includes two second arc-shaped guide grooves, which are symmetrically arranged on both sides of the second slot. The second arc-shaped guide groove extends from a position on the proximal end surface of the cartridge side rotating part in the circumferential direction and gradually increases in depth during the extension until it is connected to the second slot. Thus, as the cartridge side rotating part is inserted while rotating, the second arc-shaped guide groove guides the second insertion part in the cartridge assembly 1 to be inserted into the second slot. Because the two second arc-shaped guide grooves gradually increase in depth towards the second slot between them, the direction of the rotation insertion of the cartridge side rotating part 12 is not limited, and bidirectional automatic guidance is achieved.

[0093] In this embodiment, a plurality of second slots are arranged, and the plurality of second slots are uniformly arranged in the circumferential direction. A plurality of second guide parts are correspondingly arranged, and the plurality of second guide parts are arranged in the circumferential direction. One second slot and the two second arc-shaped guide grooves on both sides thereof are taken as a group, and a plurality of groups are the same and are uniformly arranged in the circumferential direction. In this way, the installation stroke is saved, and the installation is easy. Preferably, two second slots are arranged, so that the rotation of 90° at most can achieve successful insertion.

[0094] Because the protrusion as the first insertion part and the protrusion as the second insertion part are arranged on the inner wall of the corresponding rotation channel 3, the radial dimension of the cartridge side fixed part 11 is smaller than the radial dimension of the cartridge side rotating part 12, so as to allow the first insertion part to be inserted into the adapter side fixed part 9 through the rotation channel 3 of the adapter side rotating part 10; or the first slot and the second slot are circumferentially aligned, so as to allow the first insertion part to pass through the second slot and then pass through the first slot.

[0095] Because the cartridge side rotating part 12 and the cartridge side fixed part 11 are rotatable, the cartridge side fixed part 11 needs to be held by hand first to rotate and find the position, so the axial distance from the first insertion part to the second insertion part needs to be smaller than the axial distance between the first slot and the second slot.

[0096] In the present embodiment, the adapter side fixed part 9 and the cartridge side fixed part 11 can be circumferentially locked by other locking mechanisms (for example, the cooperation between the elastic buckle and the locking hole), and the adapter side rotating part 10 and the cartridge side rotating part 12 only bear the selectable circumferential locking function between them by the cooperation of the second slot and the second insertion part, that is, the adapter side rotating part 10 and the cartridge side rotating part 12 are selectively locked together and do not separate when rotating together. Therefore, it can be obviously seen that the size of the second insertion part is larger than that of the first insertion part, and the width of the second slot is larger than that of the first slot, so as to obtain the stable circumferential locking function.

[0097] Of course, in other embodiments, a circumferential locking assembly providing a main circumferential locking function can be arranged between the adapter side rotating part 10 and the cartridge side rotating part 12 (for example, a positioning hole can be arranged on the inner wall of the rotary channel 3 of the adapter side rotating part 10, and an elastic buckle and an elastic ring can be arranged in the cartridge side rotating part 12 of the cartridge assembly 1).

[0098] Conversely, it can be understood that if the size of the first insertion part is large enough and the working condition allows, the cooperation of the first insertion part and the first slot can replace the locking mechanism to achieve the selectable locking between the adapter side fixed part 9 and the cartridge side fixed part 11.

[0099] Embodiment 4

[0100] In the present embodiment, the difference from the embodiment 3 is that the protrusion is replaced by a plug (the shape and connection mode of the plug can be referred to Figure 5 ), the protrusion in the embodiment 3 is fixedly connected with the rotary channel 3, for example, obtained by integral molding, and the plug in the present embodiment is elastically connected to the inner wall of the rotary channel 3, and the deformation direction of the elastic connection is the axis direction of the rotary channel 3. Here, taking the example that the plug is connected to the rotary channel 3 by an elastic member and a fixed member, the distal end of the plug protrudes from the distal end of the rotary channel 3, the proximal end of the plug is connected with the distal end of the elastic member, the proximal end of the elastic member is connected with the proximal end of the fixed member, and the fixed member is connected to the side wall of the rotary channel 3. Thus, when the plug walks on the guide groove, the elastic member of the plug is compressed, and when it walks to the slot, the elastic member drives the plug to pop into the slot, thereby preventing the situation of missing the slot due to too fast rotation. The shape of the plug can be a triangle, an arc or a trapezoid formed by the distal end tapering, and the overall shape of the plug can be a plate or a rod. Among them, the proximal end of the fixed member connected with the adapter side fixed part 9 is tapered to form a triangle, an arc or a trapezoid; the distal end of the fixed member connected with the adapter side rotating part 10 does not need to be tapered.

[0101] Although the embodiments of the present application have been shown and described above, it is understood that the above-described embodiments are exemplary and are not to be construed as limiting the present application, and that modifications, substitutions, replacements and variations of the above-described embodiments can be made by those skilled in the art within the scope of the present application.
