Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to an anchor implanter and its system. Background Technology

[0002] Currently, in surgical repair of rotator cuff injuries, tendon injuries, or injuries to other soft tissues or tendons, it is usually necessary to use anchor implantation devices to implant anchors into the body to achieve fixation. Specifically, anchors can be used to directly fix soft tissues to bone, or anchors can be used in conjunction with patches to fix tendons. Regardless of the method, it is necessary to ensure that the implantation is stable until healing is complete.

[0003] In actual surgical procedures, fixation is typically not achieved using only a single anchor, especially in large rotator cuff tears where multiple anchors are needed in conjunction with patches to secure the tendon. However, current anchor implantation devices can only trigger the implantation of a single anchor. This means that during surgery, the surgeon must assemble and implant the anchor and its implantation device repeatedly for each anchor. This repetitive process not only reduces the accuracy of anchor implantation but also prolongs the surgical time, thereby increasing surgical risks. Summary of the Invention

[0069] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0070] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0071] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0073] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0075] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0076] Existing anchors for tendon patch implants are all individually inserted, requiring multiple anchors to achieve proper fixation. The need for individual anchor insertion prolongs surgery time, increases the surgeon's workload and difficulty, and extends the surgeon's operation time. This solution integrates the anchors into a single implantation system, allowing for continuous anchor activation, thereby reducing the surgeon's workload, minimizing instrument failure, and reducing surgical time.

[0077] Example

[0078] This embodiment provides an anchor implanter and its system, which can be used to continuously eject anchors, enabling the ejection and implantation of multiple anchors required for the procedure, without the need to reload the anchors during the operation, thus effectively simplifying the surgical procedure.

[0079] See Figures 1-13As shown, the anchor implanter includes an implantation device 11 and a drive handle 12.

[0080] The implantation device 11 includes an outer tube 111 and a push rod 112; the push rod 112 is located inside the outer tube 111 and is movable along the axial direction of the outer tube 111; the push rod 112 is configured to accommodate a plurality of anchors 2, all of which are located inside the outer tube 111; the outer tube 111 and the push rod 112 are provided with a one-way propulsion structure; the one-way propulsion structure is configured to drive the anchors 2 to move unidirectionally; for example, the one-way propulsion structure can drive the anchors 2 to move unidirectionally toward the distal end of the outer tube 111 and can prevent the anchors 2 from moving toward the proximal end of the outer tube 111.

[0081] The drive handle 12 includes a housing 121, a pressing handle 123, a transmission device 124, and an elastic element 126; the transmission device 124 and the elastic element 126 are both located inside the housing 121; at least part of the pressing handle 123 is located inside the housing 121, and at least part of the pressing handle 123 can extend out of the housing 121.

[0082] Along the axial direction of the outer tube 111, the outer tube 111 includes corresponding distal and proximal ends, and the push rod 112 includes corresponding distal and proximal ends; the proximal end of the outer tube 111 is connected to the housing 121, for example, the proximal end of the outer tube 111 is fixedly connected to the housing 121. The proximal end of the push rod 112 is connected to the output end of the transmission device 124, for example, the proximal end of the push rod 112 is fixedly connected to the output end of the transmission device 124.

[0083] The pressing handle 123 is configured to drive the transmission device 124 to move when pressed, thereby driving the push rod 112 to move along the axial direction of the outer tube 111 toward the distal end of the outer tube 111, while driving all the anchor pins 2 to move with the push rod 112 toward the distal end of the outer tube 111, and simultaneously driving the elastic element 126 to produce an elastic deformation that drives the transmission device 124 to reset.

[0084] The elastic element 126 is configured to drive the transmission device 124 to reset when the pressing handle 123 is not pressed, thereby driving the push rod 112 and the pressing handle 123 to reset. At this time, the anchor pin 2 does not move with the push rod 112 under the action of the unidirectional propulsion structure. When the pressing handle 123 is not pressed, for example, the pressing force on the pressing handle 123 is withdrawn.

[0085] Optionally, the elastic element 126 may be, for example, an elastic element such as a spring.

[0086] In this embodiment, the anchor implanter, by pressing down the handle 123, drives the transmission device 124 to push all the anchors 2 in the push rod 112 toward the distal end of the outer tube 111. Due to the reaction force of the elastic element 126, the transmission device 124 moves back toward the proximal end of the outer tube 111, causing the push rod 112 and the handle 123 to return to their initial positions. This completes one cycle. By continuously pressing down the handle 123, the anchors 2 can be continuously pushed out.

[0087] The anchor implanter described in this embodiment includes an implantation device 11 and a drive handle 12. The implantation device 11 includes an outer tube 111 and a push rod 112. The drive handle 12 includes a housing 121, a pressing handle 123, a transmission device 124, and an elastic element 126. The pressing handle 123 is driven by pressing, which in turn drives the transmission device 124 to move, thereby driving the push rod 112 to move along the axial direction of the outer tube 111 toward the distal end of the outer tube 111. At the same time, all anchors 2 are driven to move toward the distal end of the outer tube 111 along with the push rod 112. When the pressure of the pressing handle 123 is returned, the elastic element 126 can drive the transmission device 124 to reset, thereby driving the push rod 112 and the pressing handle 123 to reset. At this time, the anchor 2 does not move with the push rod 112, which can realize the insertion of multiple anchors 2 required for the procedure, and there is no need to reload the anchors during the operation. This can effectively simplify the operation and effectively solve the technical problems of poor anchor insertion accuracy and long operation time caused by the need to assemble and insert the anchor and anchor insertion device for each anchor in the prior art.

[0088] See Figure 5 , Figure 6 and Figure 13 As shown, in the optional embodiment, the unidirectional propulsion structure includes a fixing hole 1111 on the outer tube 111 and a slot wing 1121 in the push rod 112.

[0089] The push rod 112 includes a push rod portion 1124 and an anchor groove 1122 disposed in the push rod portion 1124. The anchor groove 1122 extends along the axial direction of the push rod 112 and opens at the distal end of the push rod 112. The axial direction of the push rod 112 is parallel to the axial direction of the outer tube 111.

[0090] Along the axial direction of the push rod 112, a plurality of slot wings 1121 are spaced apart on the push rod 112; the anchor slot 1122 is configured to accommodate a plurality of anchors 2, and the slot wings 1121 are configured to abut against the anchors 2 to drive the anchors 2 to move with the push rod 112 toward the distal end of the outer tube 111.

[0091] Along the axial direction of the outer tube 111, a plurality of fixing holes 1111 are spaced apart on the outer tube 111. For example, the plurality of fixing holes 1111 are evenly spaced on the outer tube 111; the fixing holes 1111 are configured to engage the fixing wings 21 of the anchor 2. The fixing holes 1111 engage the fixing wings 21 of the anchor 2 to position and limit the position of the anchor 2 within the push rod 112.

[0092] See Figure 11 As shown, in the optional embodiment, the anchor 2 includes an anchor platform portion 22 and two anchor guide portions 23; the two anchor guide portions 23 are connected to both ends of the anchor platform portion 22, and the two anchor guide portions 23 are located on the same side of the anchor platform portion 22; that is, the anchor 2 is shaped like a "door".

[0093] Optionally, the anchor platform portion 22 is provided with a fixing wing 21; on the anchor platform portion 22, the surface where the fixing wing 21 is located is adjacent to the surface where the anchor guide portion 23 is located.

[0094] See Figure 11 As shown, optionally, along the axial direction of the fixing hole 1111, the height of the distal end of the fixing wing 21 gradually increases to the proximal end; the distal end of the fixing wing 21 is flush with the anchor platform portion 22, and the proximal end of the fixing wing 21 protrudes beyond the anchor platform portion 22; it can be understood that the fixing wing 21 is inclined, the distal end of the fixing wing 21 is thicker than the proximal end of the fixing wing 21, and the proximal end of the fixing wing 21 has the same thickness as the anchor platform portion 22. Through the structural design of the fixing wing 21, it is beneficial for the anchor 2 to move towards the distal end of the outer tube 111 with the push rod 112, which is beneficial for the anchor 2 to be smoothly pushed out without damaging the structure of the anchor 2.

[0095] See Figure 11 As shown, optionally, there are two fixed wings 21, which are coaxial and symmetrically arranged. By setting the two fixed wings 21 coaxially and symmetrically, the stability and firmness of the fixed wings 21 when they are snapped together can be effectively guaranteed.

[0096] See Figure 11 As shown, optionally, an anchor insertion cone 24 is provided at the proximal end of the anchor guide portion 23 away from the anchor platform portion 22; the anchor insertion cone 24 has a tip; the anchor insertion cone 24 facilitates the implantation of the anchor 2.

[0097] Optionally, each anchor guide 23 is provided with one or more barbs 25, and the barbs 25 of two anchor guides 23 are arranged opposite to each other. The barbs 25 effectively ensure that the anchor 2 can be fixed in the preset position after being inserted.

[0098] See Figures 6-13As shown, in an optional embodiment, the anchor 2 is housed in the anchor groove 1122 of the anchor implanter 1, and the anchor guide 23 abuts against the push rod 1124; for example, the anchor guide 23 and the push rod 1124 are interference-fitted.

[0099] For example, specifically, the proximal end of the slot wing 1121 is a wing inclined section 11211; the distal end of the slot wing 1121 is a wing planar section 11213 perpendicular to the axial direction of the push rod 112, and the wing planar section 11213 is configured to abut against the anchor platform portion 22 of the anchor pin 2; the cross-sectional area of ​​the wing inclined section 11211 is not greater than the cross-sectional area of ​​the wing planar section 11213; the anchor groove 1122 is open at both ends along the axial direction of the fixing hole 1111 to divide the push rod portion 1124 into two push rod sub-parts, and the two push rod sub-parts are configured to clamp the anchor pin 2, for example, the anchor guide portion 23 is interference-fitted with the push rod sub-part; wherein, the axial direction of the fixing hole 1111 intersects with the axial direction of the outer tube 111, for example, the axial direction of the fixing hole 1111 is perpendicular to the axial direction of the outer tube 111.

[0100] Optionally, the fixing hole 1111 is a circular hole, and correspondingly, the fixing wing 21 is a circular bevel, and the fixing wing 21 is located on the center line of the anchor 2.

[0101] Optionally, multiple slot wings 1121 are symmetrically arranged on the two push rod sub-sections.

[0102] Optionally, if the number of fixing holes 1111 is N1 and the number of pairs of slot wings 1121 is N2, then N2 = N1 - 1. That is, the number of pairs of slot wings 1121 is one less than the number of fixing holes 1111. For example... Figure 6 and Figure 13 As shown, the anchor 2 near the proximal end of the push rod 112 is driven by the push rod part 1124 to move toward the distal end of the outer tube 111 when the push rod 112 moves toward the distal end of the outer tube 111.

[0103] In this embodiment, the specific number of fixing holes 1111 and the specific number of pairs of slot wings 1121 can be set according to actual needs.

[0104] See Figure 13 As shown in the figure, the left figure is a structural schematic diagram of the anchor 2, the outer tube 111 and the push rod 112, the middle figure is a structural schematic diagram of the left figure without the push rod 112, and the right figure is a structural schematic diagram of the left figure without the outer tube 111. In some embodiments, along the axial direction of the outer tube 111, the distance L1 between two adjacent fixing holes 1111 is the same as the distance L2 between two adjacent slot wings 1121.

[0105] Optionally, the spacing L1 is configured to be greater than the length LC of the anchor 2 so that the anchor 2 can be accommodated in the anchor groove 1122.

[0106] Optionally, along the axial direction of the outer tube 111, the difference between the spacing L1 and the length of the slot wing 1121 is configured to be greater than or equal to the length LC of the anchor 2.

[0107] See Figure 6 As shown, in the optional scheme of this embodiment, a wing transition section 11212 connects the wing inclined section 11211 and the wing planar section 11213; the wing transition section 11212 is a column or a cone; the wing inclined section 11211, the wing transition section 11212 and the wing planar section 11213 transition smoothly; through the wing transition section 11212, it is beneficial for the anchor 2 to move towards the far end of the outer tube 111 with the push rod 112, which is beneficial for the anchor 2 to be pushed out smoothly without damaging the anchor 2 structure.

[0108] See Figure 6 As shown, in an optional embodiment, the push rod portion 1124 is further provided with an auxiliary groove 1123; the auxiliary groove 1123 communicates with the proximal end of the anchor groove 1122, and the opening of the auxiliary groove 1123 is smaller than the opening of the anchor groove 1122; the auxiliary groove 1123 helps to improve the tension of the push rod portion 1124, such as helping to change the distance between the two push rod portions, facilitating the smooth ejection of the anchor 2 at the distal end. Because the opening of the auxiliary groove 1123 is smaller than the opening of the anchor groove 1122, when the push rod 112 moves toward the distal end of the outer tube 111, the step formed by the push rod portion 1124 at the junction of the auxiliary groove 1123 and the anchor groove 1122 can drive the anchor 2 toward the distal end of the outer tube 111.

[0109] See Figure 13 As shown, optionally, along the axial direction of the push rod 112, the length LF of the auxiliary groove 1123 is not less than the distance L2 between two adjacent slot wings 1121.

[0110] Optionally, the outer tube 111 and / or the push rod 112 are axisymmetric structures.

[0111] See Figure 5 and Figure 13 As shown, in an optional embodiment, the outer tube 111 has an outer tube cavity 1113 that accommodates the push rod 112; the outer tube cavity 1113 extends along the axial direction of the outer tube 111 and is open at both ends.

[0112] Along the axial direction of the fixing hole 1111, at least one surface of the push rod 112 abuts against the outer tube 111; along the axial direction perpendicular to the fixing hole 1111, there is a gap between the surface of the push rod 112 and the outer tube 111. The gap between the surface of the push rod 112 and the outer tube 111 ensures that the outer tube 111 does not interfere with the expansion of the push rod portion 1124 when the anchor 2 is pushed out.

[0113] Optionally, the distal end of the outer tube 111 is provided with an insertion cone 1112; the insertion cone 1112 has a tip, for example, the insertion cone 1112 is a sharp cutting edge. The insertion cone 1112 facilitates the penetration of the tendon and fixes the distal position of the outer tube 111.

[0114] Optionally, the cross-section of the outer cavity 1113 is dumbbell-shaped, figure-eight-shaped, or other shapes. By adopting a dumbbell-shaped or figure-eight-shaped cross-section, the push rod 112 can travel along the outer cavity 1113 of the outer tube 111, thereby ensuring the compatibility between the push rod and the anchor to a certain extent.

[0115] Optionally, the number of insertion cones 1112 is two, and the two insertion cones 1112 are arranged symmetrically;

[0116] Optionally, the two insertion cones 1112 are machined from the outer tube 111 by removing material, so as to simplify the structure of the outer tube 111 and facilitate the production and processing of the outer tube 111.

[0117] In this embodiment, the anchor implanter has an anchor guide portion 23 that is interference-fitted with the push rod portion 1124. The push rod portion 1124 clamps the anchor guide portion 23 (e.g., two push rod sub-parts clamp the anchor guide portion 23), and with the push of the slot wing 1121, the anchor 2 moves along the axial direction of the outer tube 111 toward the distal end of the outer tube 111. When the distal anchor 2 is pushed out, the push rod portion 1124 expands outward due to the limitation of the slot wing 1121 (e.g., two push rod sub-parts expand outward). During expansion, the push rod portion 1124 and the outer tube cavity 1113 have a gap, so the expansion of the push rod portion 1124 is not interfered with. At this time, the auxiliary groove 1123 at the tail plays a role in relaxing the tension, which allows the distal anchor 2 to be pushed out smoothly. After the previous anchor 2 is pushed out, the push rod 112 will be reset under the drive of the elastic element 126 (i.e., move towards the proximal end of the outer tube 111), and the fixing wing 21 of the anchor 2 will be inserted into the previous fixing hole 1111, thereby realizing the step of continuously pushing out the anchors.

[0118] See Figure 1-Figure 4 and Figure 10 As shown, in an optional embodiment, the drive handle 12 further includes a slider 125; the slider 125 is connected between the push rod 112 and the transmission device 124, and the distal end of the slider 125 is fixedly connected to the proximal end of the push rod 112, and the proximal end of the slider 125 is hinged to the output end of the transmission device 124; the slider 125 facilitates the improvement of the stability of the anchor implanter during movement, which is beneficial to the implantation of the anchor 2.

[0119] Optionally, the outer casing 121 is provided with a guide groove 1212 that mates with the slider 125. The guide groove 1212 extends along the axial direction of the outer tube 111. The guide groove 1212 reduces the probability of the slider 125 deviating during sliding motion and also limits the sliding distance of the slider 125. Optionally, the slider 125 is provided with a slider rod 1252, which is inserted into the guide groove 1212 to realize the reciprocating motion of the slider 125.

[0120] Optionally, the near end of the slider 125 has a slider keyway 1254, which is hinged to the output end of the transmission device 124 via a pin.

[0121] Optionally, the slider 125 is provided with a push rod groove 1253 to receive the proximal end of the push rod 112, for example, the shape of the push rod groove is the same as that of the push rod 112. The push rod groove 1253 facilitates fixing the push rod 112 to the slider 125.

[0122] In this embodiment, when the pressing handle 123 is pressed, the transmission device 124 drives the slider 125 to move along the axial direction of the outer tube 111 toward the far end of the outer tube 111. When it moves to the farthest point of the guide groove 1212, the pressing handle 123 is released, and the elastic element 126 drives the slider 125 back to the initial position.

[0123] See Figure 1-Figure 4 As shown, in an optional embodiment, the transmission device 124 includes a first rod 1241, a second rod 1242, and a third rod 1243. The distal end of the first rod 1241 is the output end of the transmission device 124, and the proximal end of the first rod 1241 is hinged to the distal end of the second rod 1242. The proximal end of the second rod 1242 is pivotally connected to the housing 121. One end of the third rod 1243 is pivotally connected to the pressing handle 123, and the other end of the third rod 1243 is hinged to the second rod 1242. The hinge position of the third rod 1243 is located between the proximal and distal ends of the second rod 1242. Through the first rod 1241, the second rod 1242, and the third rod 1243, the pressing force pressed on the pressing handle 123 can be effectively transmitted.

[0124] See Figure 1-Figure 4 and Figure 8As shown, in an optional embodiment, the drive handle 12 further includes a fixing block 122 connected between the outer tube 111 and the outer shell 121; the fixing block 122 includes a fixing first part 1222, a fixing second part 1223, and a fixing third part 1224 connected in sequence; the fixing block 122 also includes a fixing block through hole 1221 penetrating the fixing first part 1222, the fixing second part 1223, and the fixing third part 1224; the cross-sectional area of ​​the fixing second part 1223 is smaller than that of the fixing third part 1224. The cross-sectional area of ​​part 1222 and the cross-sectional area of ​​fixed part 1224 are, for example, the fixed block 122 is I-shaped; the proximal end of the outer tube 111 is inserted into the through hole 1221 of the fixed block and is fixedly connected to the fixed block 122, for example, the proximal end of the outer tube 111 is aligned with and fixed to the cross-section of the fixed block 122; the push rod 112 extends out of the through hole 1221 of the fixed block and is connected to the output end of the transmission device 124; the outer tube 111 can be firmly fixed to the outer shell 121 through the fixed block 122.

[0125] See Figure 1-Figure 4 and Figure 7 As shown, in an optional embodiment, a fixing block groove 1213 is provided at the distal end of the outer casing 121; the fixing block 122 is inserted into the fixing block groove 1213, thereby fixing the fixing block 122 to the outer casing 121. Specifically, the fixing second part 1223 and the fixing third part 1224 are both accommodated in the fixing block groove 1213, and the shape of the fixing block groove 1213 is a stepped shape adapted to the fixing second part 1223 and the fixing third part 1224; the fixing first part 1222 is located outside the fixing block groove 1213.

[0126] See Figure 7 As shown, in an optional embodiment, the outer casing 121 includes a first outer casing portion and a second outer casing portion that cooperate with each other. A transmission protrusion 1211 is provided in the first outer casing portion, and a transmission groove 1216 that cooperates with the transmission protrusion 1211 is provided in the second outer casing portion. The cooperation between the transmission protrusion 1211 and the transmission groove 1216 makes the assembly of the outer casing 121 more stable. Optionally, the transmission device 124 can be rotatably connected to the transmission protrusion 1211 or the transmission groove 1216, for example, the proximal end of the second rod 1242 is pivotally connected to the transmission protrusion 1211 or the transmission groove 1216.

[0127] See Figure 1-Figure 4 and Figure 7 As shown, in an optional embodiment, the elastic element 126 is sleeved on the push rod 112, and one end of the elastic element 126 abuts against the fixing block 122, while the other end of the elastic element 126 abuts against the slider 125. Optionally, the slider 125 is provided with an elastic element hole 1251 for accommodating the elastic element 126, and the elastic element hole 1251 is connected to the push rod groove 1253. The elastic element hole 1251 facilitates the installation and guidance of the elastic element 126.

[0128] In this embodiment, when the handle 123 is pressed, the transmission device 124 can drive the slider 125 to move to the far end of the outer tube 111, while compressing the elastic element 126 to generate elastic deformation that drives the slider 125 to reset; when the handle 123 is not pressed, the elastic element 126 can drive the slider 125 to reset, thereby driving the transmission device 124 to reset.

[0129] In an optional embodiment, the outer shell 121 is cylindrical; the cylindrical outer shell 121 is more suitable for the human hand.

[0130] See Figure 1-Figure 4 , Figure 7 and Figure 9 As shown, in an optional embodiment, the distal end of the pressing handle 123 is hinged to the housing 121, and a blocking protrusion 1233 located inside the housing 121 is provided at the proximal end of the pressing handle 123. The blocking protrusion 1233 is configured to prevent the proximal end of the pressing handle 123 from detaching from the housing 121. The blocking protrusion 1233 can be used to abut against the housing 121 to prevent the proximal end of the pressing handle 123 from detaching from the housing 121.

[0131] Optionally, a handle protrusion 1214 is provided in the first part of the housing, and a handle recess 1215 is provided in the second part of the housing to mate with the handle protrusion 1214. The mating of the handle protrusion 1214 and the handle recess 1215 makes the assembly of the housing 121 and the pressing handle 123 more stable. Optionally, the pressing handle 123 is fitted onto the handle protrusion 1214 to allow the pressing handle 123 to rotate. For example, the pressing handle 123 is provided with a handle rotation through hole 1231 that mates with the handle protrusion 1214.

[0132] Optionally, the pressing handle 123 is provided with a handle rotation through hole 1231 that mates with the handle protrusion 1214.

[0133] Optionally, the pressing handle 123 is provided with a transmission device fixing hole 1232; the transmission device fixing hole 1232 is rotatably connected to one end of the third rod 1243 via a pin.

[0134] Optionally, the pressing handle 123 is a hollow structure.

[0135] In this embodiment, the pressing handle 123 is a firing device that can continuously push out the anchor implantation system.

[0136] See Figures 1-13 As shown, this embodiment also provides an anchor implantation system, including an anchor 2 and an anchor implanter 1 as described in any of the above embodiments.

[0137] The anchor 2 is housed in the anchor groove 1122 of the anchor implanter 1, and the anchor guide 23 of the anchor 2 abuts against the push rod 1124; the fixing wing 21 is engaged in the fixing hole 1111 of the anchor implanter 1.

[0138] The slot wing 1121 of the anchor inserter 1 abuts against the side of the anchor platform 22 that is away from the anchor guide 23.

[0139] Optionally, the anchor guide portion 23 of the anchor 2 is interference-fitted with the push rod portion 1124, and the push rod portion 1124 clamps the anchor guide portion 23 (e.g., two push rod sub-parts clamp the anchor guide portion 23). With the push of the slot wing 1121, the anchor 2 moves along the axial direction of the outer tube 111 toward the distal end of the outer tube 111. When the distal anchor 2 is pushed out, the push rod portion 1124 expands outward due to the limitation of the slot wing 1121. For example, if two push rod sub-parts expand outward, the push rod portion 1124 and the outer tube cavity 1113 have a gap during expansion, so as not to interfere with the outward expansion of the push rod portion 1124. At this time, the auxiliary groove 1123 located at the tail plays a role in relaxing the tension, which allows the distal anchor 2 to be pushed out smoothly. After the previous anchor 2 is pushed out, the push rod 112 will be reset under the drive of the elastic element 126 and the slider 125 (i.e., move towards the near end of the outer tube 111), and the fixing wing 21 of the anchor 2 will be inserted into the previous fixing hole 1111, thereby realizing the step of continuously pushing out the anchors.

[0140] The anchor implantation system provided in this embodiment includes the aforementioned anchor implanter. The technical features of the disclosed anchor implanter are also applicable to this anchor implantation system, and the technical features of the disclosed anchor implanter will not be described again. The anchor implantation system in this embodiment has the advantages of the aforementioned anchor implanter, and the advantages of the disclosed anchor implanter will not be described again here.

[0141] To better understand the anchor implanter and system described in this embodiment, the working principle is briefly described below:

[0142] The fixing wing 21 of the anchor 2 engages with the fixing hole 1111 of the outer tube 111, and the push rod part 1124 of the push rod 112 clamps the anchor guide part 23 of the anchor 2. When the pressing handle 123 is pressed, the transmission device 124 drives the slider 125 to move toward the far end of the outer tube 111. The slider 125 is connected to the push rod 112, and the outer tube 111 is fixed on the fixing block 122 of the drive handle 12. Therefore, the push rod moves relative to the outer tube toward the far end of the outer tube 111, causing the anchor 2 to be pushed out toward the far end of the outer tube 111. Due to the elastic restoring force of the elastic element 126, the slider moves toward the near end of the outer tube 111, causing the pressing handle and the push rod to return to their original positions. However, due to the structural limitations of the slot wing 1121 and the fixing wing 21, the anchor can only move forward (push out toward the far end of the outer tube 111). The anchor that was in the position of the previous anchor moves forward one step and reaches the position of the previous anchor. Press the handle again to drive the push rod forward and drive the anchor forward. The next anchor will move forward one position again. Press the handle 1, 2, and 3 continuously to achieve the requirement of continuously pushing out the anchor.

[0143] The following is a brief description of the anchor implantation surgical procedure:

[0144] In rotator cuff tear surgery, multiple anchors are needed for fixation with a patch implant. First, guide anchor 2 (insert cone 24) to the desired anchor placement location. Insert anchor 24 into the tendon area, and simultaneously press handle 123 to eject and fix one anchor; the handle will then spring back. Next, insert anchor 24 into the location of the second anchor placement, press the handle again to eject and fix the second anchor. Repeat this process multiple times to fix the desired areas.

[0145] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
