Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an anchor implanter and a system thereof. Background Art

[0002] Currently, in repair surgeries for injuries to the rotator cuff and tendons, or other soft tissues or tendons, it is usually necessary to use an anchor implantation device to implant anchors into the human body to achieve the purpose of fixation. Specifically, the soft tissue can be directly fixed to the bone through the anchor, or the anchor can be used in combination with a patch to fix the tendon. Regardless of the method, the implant must be stable until healing is complete.

[0003] In actual surgery, fixation with a single anchor is not usually performed, especially in large rotator cuff tear surgeries, where multiple anchors and a patch are required to secure the tendon. However, existing anchor implantation devices can only activate the implantation of a single anchor. This means that for each anchor implanted during surgery, the surgeon must assemble and implant the anchor and the anchor implantation device again. This repetitive operation not only reduces the accuracy of anchor implantation but also prolongs the operation, thereby increasing surgical risks. Summary of the Invention

[0028] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0029] Existing anchors for tendon patch implants are inserted individually, requiring multiple anchors to achieve effective fixation. These multiple anchors require separate insertion, prolonging the surgery and increasing the surgeon's operational complexity and operating time. This solution integrates the anchors into a single implant system, enabling continuous activation of the anchors. This reduces operational complexity, instrument failure, and surgical time.

[0030] Example This embodiment provides an anchor implanter and a system thereof, which can be used to continuously push out anchors, thereby enabling the push-out and implantation of multiple anchors required for the procedure, and eliminating the need to reload the anchors during the operation, thereby effectively simplifying the surgical operation.

[0031] See also Figures 1-13 As shown, the anchor implanter includes an implantation device 11 and a driving handle 12 .

[0032] The implant device 11 includes an outer tube 111 and a push rod 112; the push rod 112 is located inside the outer tube 111 and can move axially along the outer tube 111; the push rod 112 is configured to accommodate multiple 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 unidirectional propulsion structure; the unidirectional propulsion structure is configured to drive the anchor 2 to move unidirectionally; for example, the unidirectional propulsion structure can drive the anchor 2 to move unidirectionally toward the distal end of the outer tube 111, and can prevent the anchor 2 from moving toward the proximal end of the outer tube 111.

[0033] The driving handle 12 includes a shell 121, a pressing handle 123, a transmission device 124 and an elastic member 126; the transmission device 124 and the elastic member 126 are both located inside the shell 121; at least part of the pressing handle 123 is located inside the shell 121, and at least part of the pressing handle 123 can extend from the shell 121.

[0034] 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.

[0035] 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, and simultaneously driving all the anchors 2 to move toward the distal end of the outer tube 111 along the push rod 112, and simultaneously driving the elastic member 126 to generate elastic deformation to drive the transmission device 124 to reset.

[0036] The elastic member 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 2 does not move with the push rod 112 under the action of the one-way propulsion structure. When the pressing handle 123 is not pressed, for example, the pressing force on the pressing handle 123 is withdrawn.

[0037] Optionally, the elastic member 126 is an elastic element such as a spring.

[0038] In this embodiment, the anchor implanter is configured so that by pressing down on the pressing handle 123, the actuator 124 moves, pushing all anchors 2 in the push rod 112 toward the distal end of the outer tube 111. The reaction force of the elastic member 126 resets the actuator 124 toward the proximal end of the outer tube 111, returning the push rod 112 and the pressing handle 123 to their initial positions. This constitutes one cycle. Continuously pressing down on the pressing handle 123 allows for continuous ejection of the anchors 2.

[0039] The anchor implanter in this embodiment includes an implant device 11 and a driving handle 12. The implant device 11 includes an outer tube 111 and a push rod 112. The driving handle 12 includes a housing 121, a pressing handle 123, a transmission device 124, and an elastic member 126. The pressing handle 123 is driven by pressing to drive 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, and at the same time driving all the anchors 2 to move toward the distal end of the outer tube 111 along with the push rod 112. When the pressing force on the pressing handle 123 is returned, the elastic member 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, and the multiple anchors 2 required for the operation can be pushed out and implanted, and there is no need to reload the anchors during the operation, which can effectively simplify the surgical operation and effectively solve the technical problems in the prior art that each anchor implantation requires the assembly and implantation of the anchor and the anchor implantation device to be completed once. The anchor implantation accuracy is poor and the operation time is long.

[0040] See also Figure 5 、 Figure 6 and Figure 13 As shown, in an optional solution of this embodiment, the one-way propulsion structure includes a fixing hole 1111 provided on the outer tube 111 and a slot wing 1121 provided in the push rod 112 .

[0041] 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 axially along 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 .

[0042] Along the axial direction of the push rod 112 , multiple slot wings 1121 are spaced apart on the push rod 112 ; the anchor groove 1122 is configured to accommodate multiple anchors 2 , and the slot wings 1121 are configured to abut against the anchor 2 to drive the anchor 2 to move toward the distal end of the outer tube 111 along the push rod 112 .

[0043] Multiple fixing holes 1111 are spaced apart along the axial direction of the outer tube 111. For example, the multiple fixing holes 1111 are evenly spaced apart 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 restrict the position of the anchor 2 within the push rod 112.

[0044] See also Figure 11 As shown, in an optional solution of this 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 as a whole is in the shape of a "door".

[0045] Optionally, the anchor platform portion 22 is provided with fixing wings 21 ; on the anchor platform portion 22 , the surface where the fixing wings 21 are located is adjacent to the surface where the anchor guide portion 23 is located.

[0046] See also Figure 11 As shown, optionally, along the axial direction of the fixing hole 1111, the height of the fixing wing 21 gradually increases from the distal end to the proximal end of the fixing wing 21; 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 from the anchor platform portion 22. It can be understood that the fixing wing 21 is in the shape of a bevel, 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 is the same thickness as the anchor platform portion 22. The structural design of the fixing wing 21 facilitates the anchor 2 to move to a preset position with the push rod 112 toward the distal end of the outer tube 111, and facilitates the smooth ejection of the anchor 2 without damaging the structure of the anchor 2.

[0047] See also Figure 11 As shown, optionally, there are two fixed wings 21, and the two fixed wings 21 are coaxial and symmetrically arranged; by the coaxial arrangement of the two fixed wings 21 and the symmetrical arrangement of the two fixed wings 21, the stability and firmness of the fixed wings 21 when being clamped can be effectively guaranteed.

[0048] See also 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 pointed end; the anchor insertion cone 24 can facilitate the implantation of the anchor 2.

[0049] Optionally, each anchor guide 23 is provided with one or more barbs 25, and the barbs 25 of the two anchor guides 23 are arranged opposite to each other. The barbs 25 effectively ensure that the anchor 2 can be fixed at a preset position after implantation.

[0050] See also Figure 6-Figure 13 As shown, in an optional solution of this embodiment, the anchor 2 is accommodated in the anchor groove 1122 of the anchor implanter 1, and the anchor guide portion 23 abuts against the push rod portion 1124; for example, the anchor guide portion 23 and the push rod portion 1124 are interference fit.

[0051] For example, specifically, the proximal end of the slot wing 1121 is the slot wing inclined section 11211; the distal end of the slot wing 1121 is the slot wing plane section 11213 perpendicular to the axial direction of the push rod 112, and the slot wing plane section 11213 is configured to abut the anchor platform portion 22 of the anchor 2; the cross-sectional area of the slot wing inclined section 11211 is not larger than the cross-sectional area of the slot wing plane section 11213; the anchor groove 1122 is open at both axial ends of the fixing hole 1111 to separate the push rod portion 1124 into two push rod sub-portions, and the two push rod sub-portions are configured to clamp the anchor 2, for example, the anchor guide portion 23 is interference fit with the push rod sub-portion; 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.

[0052] Optionally, the fixing hole 1111 is a circular hole, and correspondingly, the fixing wing 21 is a circular inclined surface, and the fixing wing 21 is located on the center line of the anchor 2.

[0053] Optionally, a plurality of slot wings 1121 are symmetrically arranged on the two push rod sub-parts.

[0054] Optionally, the number of the fixing holes 1111 is N1, and the number of pairs of the slot wings 1121 is N2, then N2=N1-1. That is, the number of pairs of the slot wings 1121 is one less than the number of the fixing holes 1111. Figure 6 and Figure 13 As shown, when the push rod 112 moves toward the distal end of the outer tube 111 , the anchor 2 near the proximal end of the push rod 112 is driven by the push rod portion 1124 to move toward the distal end of the outer tube 111 .

[0055] In this embodiment, the specific number of the fixing holes 1111 and the specific number of pairs of the slot wings 1121 can be set according to actual needs.

[0056] See also Figure 13As shown, the left figure is a schematic diagram of the structure of the anchor 2, outer tube 111, and push rod 112, the middle figure is a schematic diagram of the structure of the left figure without the push rod 112, and the right figure is a schematic diagram of the structure of the left figure without the outer tube 111. In some embodiments, along the axial direction of the outer tube 111, the spacing L1 between two adjacent fixing holes 1111 is the same as the spacing L2 between two adjacent locking wings 1121.

[0057] Optionally, the distance 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 .

[0058] Optionally, along the axial direction of the outer tube 111 , the difference between the distance 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 .

[0059] See also Figure 6 As shown, in the optional scheme of this embodiment, a wing transition section 11212 is connected between the wing inclined section 11211 and the wing plane 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 plane section 11213 are smoothly transitioned; through the wing transition section 11212, the anchor nail 2 is facilitated to move toward the distal end of the outer tube 111 along with the push rod 112, which is conducive to the smooth pushing out of the anchor nail 2 without damaging the structure of the anchor nail 2.

[0060] See also Figure 6 As shown, in an optional solution of this embodiment, the push rod portion 1124 is further provided with an auxiliary groove 1123; the auxiliary groove 1123 is connected to the proximal end of the anchor groove 1122, and the notch of the auxiliary groove 1123 is smaller than the notch of the anchor groove 1122. The auxiliary groove 1123 helps to increase the tension of the push rod portion 1124, for example, it helps to change the distance between the two push rod sub-portions, thereby facilitating the smooth ejection of the distal anchor 2. Because the notch of the auxiliary groove 1123 is smaller than the notch 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 intersection of the auxiliary groove 1123 and the anchor groove 1122 can drive the anchor 2 toward the distal end of the outer tube 111.

[0061] See also 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 .

[0062] Optionally, the outer tube 111 and / or the push rod 112 are of axisymmetric structure.

[0063] See also Figure 5 and Figure 13As shown, in an optional solution of this embodiment, the outer tube 111 has an outer tube cavity 1113 for accommodating the push rod 112; the outer tube cavity 1113 extends along the axial direction of the outer tube 111 and has openings at both ends.

[0064] 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, a gap exists 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 prevents the outer tube 111 from interfering with the expansion of the push rod portion 1124 when the anchor 2 is pushed out.

[0065] Optionally, an insertion cone 1112 is provided at the distal end of the outer tube 111 ; the insertion cone 1112 has a pointed end, for example, a sharp edge, so as to penetrate the tendon and fix the distal end of the outer tube 111 .

[0066] Optionally, the cross section of the outer lumen 1113 is in a dumbbell shape or an 8 shape, or other shapes. By adopting the dumbbell shape or the 8 shape in the cross section of the outer lumen 1113, the push rod 112 can move along the outer lumen 1113 of the outer tube 111, thereby ensuring the compatibility of the push rod and the anchor to a certain extent.

[0067] Optionally, the number of the insertion cones 1112 is two, and the two insertion cones 1112 are symmetrically arranged; Optionally, the two insert cones 1112 are formed by removing material from the outer tube 111 , so as to simplify the structure of the outer tube 111 and facilitate the production and processing of the outer tube 111 .

[0068] In the anchor implanter described in this embodiment, the anchor guide portion 23 and the push rod portion 1124 have an interference fit. 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 in conjunction with the pushing of the retaining wings 1121, the anchor 2 is moved 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 restraint of the retaining wings 1121. For example, when the two push rod sub-parts expand outward, a gap is left between the push rod portion 1124 and the outer tube lumen 1113 during expansion, thereby preventing interference with the outward expansion of the push rod portion 1124. At this time, the auxiliary groove 1123 at the tail portion acts as a tensioning force, enabling the distal anchor 2 to be smoothly pushed out. After the previous anchor 2 is pushed out, the push rod 112 as a whole will be reset (i.e., move toward the proximal end of the outer tube 111) under the drive of the elastic member 126, and the fixing wing 21 of the anchor 2 will be stuck in the previous fixing hole 1111, thereby realizing the step of continuously pushing out the anchors.

[0070] Optionally, the housing 121 is provided with a guide groove 1212 that cooperates with the slider 125. The guide groove 1212 extends along the axial direction of the outer tube 111. The guide groove 1212 can reduce the probability of the slider 125 deflecting during sliding motion and limit the sliding distance of the slider 125. Optionally, the slider 125 is provided with a slider rod 1252. The slider rod 1252 is inserted into the guide groove 1212 to enable the slider 125 to reciprocate.

[0071] Optionally, the proximal end of the slider 125 has a slider keyway 1254, and the slider keyway 1254 is hinged to the output end of the transmission device 124 through a pin.

[0073] The anchor implanter described in this embodiment, when the pressing handle 123 is pressed and moved, drives the slider 125 to move along the axial direction of the outer tube 111 toward the distal end of the outer tube 111 through the transmission device 124. When it moves to the farthest point of the guide groove 1212, the pressing handle 123 is released, and the elastic member 126 drives the slider 125 back to the initial position.

The cross-sectional area of the first part 1222 and the cross-sectional area of the fixed third part 1224, for example, the fixed block 122 is I-shaped as a whole; the proximal end of the outer tube 111 is inserted into the fixed block through hole 1221 and fixedly connected to the fixed block 122, for example, the proximal end of the outer tube 111 is aligned with the cross-section of the fixed block 122 and fixed; the push rod 112 extends out of the fixed block through hole 1221 and is connected to the output end of the transmission device 124; through the fixed block 122, the outer tube 111 can be firmly fixed to the outer shell 121.

[0076] See also Figures 1-4 and Figure 7 As shown, in an optional solution of this embodiment, a fixing block slot 1213 is provided at the distal end of the housing 121; the fixing block 122 is inserted into the fixing block slot 1213, thereby securing the fixing block 122 to the housing 121. Specifically, the second fixing portion 1223 and the third fixing portion 1224 are both accommodated within the fixing block slot 1213. The fixing block slot 1213 is shaped like a step that matches the second fixing portion 1223 and the third fixing portion 1224; the first fixing portion 1222 is located outside the fixing block slot 1213.

[0079] In this embodiment, when the pressing handle 123 is in a pressed state, the transmission device 124 can drive the slider 125 to move toward the distal end of the outer tube 111, while compressing the elastic member 126 to generate elastic deformation that drives the slider 125 to reset; when the pressing handle 123 is not pressed, the elastic member 126 can drive the slider 125 to reset, thereby driving the transmission device 124 to reset.

[0080] In an optional solution of this embodiment, the housing 121 is cylindrical; the cylindrical housing 121 is more suitable for the palm of a human body.

[0081] See also Figures 1-4 、 Figure 7 and Figure 9 As shown, in an optional solution of this embodiment, the distal end of the pressing handle 123 is hinged to the housing 121, and the proximal end of the pressing handle 123 is provided with a blocking boss 1233 located inside the housing 121. The blocking boss 1233 is configured to prevent the proximal end of the pressing handle 123 from being separated from the housing 121. The blocking boss 1233 can be used to abut the housing 121 to prevent the proximal end of the pressing handle 123 from being separated from the housing 121.

[0082] Optionally, a handle protrusion 1214 is provided within the first portion of the housing, and a handle recess 1215 is provided within the second portion of the housing to mate with the handle protrusion 1214.

Optionally, the pressing handle 123 is positioned over the handle protrusion 1214 to enable the pressing handle 123 to pivot. For example, the pressing handle 123 is provided with a handle rotation through-hole 1231 that mates with the handle protrusion 1214.

[0083] Optionally, the pressing handle 123 is provided with a handle rotation through hole 1231 that cooperates with the handle convex shaft 1214 .

[0084] 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 through a pin.

[0085] Optionally, the pressing handle 123 is a hollow structure as a whole.

[0086] In this embodiment, the pressing handle 123 is a firing device that can continuously push out the anchor implantation system.

[0087] See also Figures 1-13 As shown, this embodiment further provides an anchor implantation system, comprising an anchor 2 and the anchor implanter 1 described in any of the above embodiments.

[0088] The anchor 2 is accommodated in the anchor groove 1122 of the anchor implanter 1, and the anchor guide portion 23 of the anchor 2 abuts against the push rod portion 1124; the fixing wing 21 is clamped in the fixing hole 1111 of the anchor implanter 1; The slot wing 1121 of the anchor implanter 1 abuts against a surface of the anchor platform portion 22 facing away from the anchor guide portion 23 .

[0089] Optionally, the anchor guide portion 23 of the anchor 2 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 in conjunction with the pushing of the retaining wings 1121, the anchor 2 is moved axially 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 restraint of the retaining wings 1121. For example, when the two push rod sub-parts expand outward, a gap is left between the push rod portion 1124 and the outer tube lumen 1113 during expansion, thereby preventing interference with the outward expansion of the push rod portion 1124. At this time, the auxiliary groove 1123 at the tail portion acts as a tensioning force, enabling the distal anchor 2 to be smoothly pushed out. After the previous anchor 2 is pushed out, the push rod 112 as a whole will be reset (i.e., move toward the proximal end of the outer tube 111) under the driving of the elastic member 126 and the slider 125, and the fixing wing 21 of the anchor 2 will be stuck in the previous fixing hole 1111, thereby realizing the step of continuously pushing out the anchors.

[0090] The anchor implantation system provided in this embodiment includes the above-mentioned anchor implanter. The technical features of the above-mentioned anchor implanter are also applicable to the anchor implantation system, and the technical features of the above-mentioned anchor implanter are not repeated here. The anchor implantation system described in this embodiment has the advantages of the above-mentioned anchor implanter, and the advantages of the above-mentioned anchor implanter are not repeated here.

[0091] In order to better understand the anchor implanter and its system described in this embodiment, the working principle is briefly described below: The fixing wings 21 of the anchor 2 engage with the fixing holes 1111 of the outer tube 111, and the push rod portion 1124 of the push rod 112 clamps the anchor guide portion 23 of the anchor 2. Pressing the pressing handle 123 causes the slider 125 to move toward the distal end of the outer tube 111 via the transmission device 124. The slider 125 is connected to the push rod 112, and the outer tube 111 is fixed to the fixing block 122 of the driving handle 12. Therefore, the push rod moves relative to the outer tube toward the distal end of the outer tube 111, pushing the anchor 2 toward the distal end of the outer tube 111. The elastic restoring force of the elastic member 126 causes the slider to move toward the proximal end of the outer tube 111, driving the pressing handle and push rod to return to their original positions. However, due to the structural constraints of the retaining wings 1121 and the fixing wings 21, the anchors can only move forward (toward the distal end of the outer tube 111). The subsequent anchor moves forward one space to the position of the previous anchor. Press the pressing handle again to make the push rod drive the anchor nail forward again, and the next anchor nail moves forward one grid again. Press the pressing handle 123 continuously to achieve the requirement of continuously pushing out the anchor nails.

[0092] The following is a brief description of the anchor implantation surgical method: Rotator cuff tear surgery requires multiple anchor fixation in conjunction with a patch implant. First, guide the anchor insertion cone 24 of anchor 2 to the desired anchor placement location. Insert the anchor insertion cone 24 into the tendon area while simultaneously pressing the push handle 123. Once one anchor is pushed out and secured, the push handle will rebound. Insert the anchor insertion cone 24 to the second desired anchor placement location. Press the push handle again to push the anchor out and secure it. This completes the second anchor placement. Repeat this cycle multiple times to complete the desired fixation location.

[0093] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
