Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an actuating mechanism for a staple bundle implanting device and the staple bundle implanting device. Background Art

[0002] Benign prostatic hyperplasia is a common urological disease that is more common in elderly men. Its main clinical manifestations are progressive dysuria, frequent urination, and even urinary retention, which seriously affect the quality of life of elderly men.

[0003] Currently, minimally invasive treatments such as transurethral resection, enucleation, and various laser surgeries dominate. These methods reduce or eliminate the enlarged prostate gland within the capsule, minimizing compression or mechanical obstruction of the prostatic urethra and relieving urethral obstruction. However, these minimally invasive treatments disrupt the prostate's structural structure, leading to a high incidence of surgical complications.

[0004] Prostate bundle nail implantation is an extremely minimally invasive surgical method. By implanting a bundle nail in the blocked prostate urethra, it tightens the enlarged prostate tissue, relieves the pressure on the urethra, and restores urination. Compared with traditional electrocautery and enucleation, prostate bundle nail implantation is not only less invasive and safer, but also preserves the integrity of prostate function and avoids the complications that may be caused by traditional surgery.

[0005] Existing prostate stapler implantation devices utilize a needle slider to actuate the needle connector assembly, and a suture slider to actuate the suture actuator assembly, thereby achieving needle insertion, needle retraction, and thread retraction. When the prostate stapler implantation device is in its initial state, the needle slider is locked. When needle insertion is required, the needle slider must be unlocked. After needle insertion, the needle is retracted first, followed by thread retraction. Before needle retraction, the suture slider must be locked to prevent thread retraction from occurring. The suture slider must be unlocked when thread retraction is required. Existing prostate stapler implantation devices utilize complex locking and unlocking mechanisms for the needle and suture sliders, increasing assembly cost and difficulty. Utility Model Content

[0108] The following is based on Figures 1 to 24 The staple bundle implantation device of the present invention is described in detail.

[0109] In this embodiment, if Figure 7 、 Figure 17 、 Figure 18 、 Figures 22 to 24 As shown, the stapler implantation device 100 includes an implantation cartridge 1 and an operating body 2. The implantation cartridge 1 includes a puncture needle assembly 11, a stapler wire assembly 12, and a clamping and cutting assembly 13. The puncture needle assembly 11 includes a puncture needle 112 and a distal anchor 113. The distal anchor 113 is pre-placed within the hollow puncture needle 112. The stapler wire assembly 12 includes a stapler wire 122. The clamping and cutting assembly 13 includes a proximal anchor 131 and a cutter 132. When the operating body 2 operates the distal anchor 113 to implant it into the distal side of the prostate, the stapler wire 122 passes through the prostate, one end of the stapler wire 122 connects to the distal anchor 113, and the other end of the stapler wire 122 is located proximal to the prostate. Then, the clamping and cutting assembly 13 operates the proximal anchor 131 to clamp the stapler wire 12 on the proximal side of the prostate, and the cutter 132 cuts the stapler wire 12, completing a single stapler.

[0110] like Figures 1 to 10 As shown, the operating body 2 includes a first driving mechanism 21, an actuating mechanism 22, a second driving mechanism 24 and a housing 27. The first driving mechanism 21 includes a first motor 211, a first gear 212 and a first rack 213 that are meshed with each other, and the first gear 212 is coaxially connected to the first output shaft 2111 of the first motor 211. The second driving mechanism 24 includes a second motor 241, a second gear 242 and a second rack 243 that are meshed with each other, and the second gear 242 is coaxially connected to the second output shaft 2411 of the second motor 241. The actuating mechanism 22 includes a needle slider 221, a thread slider 222, a first mounting member 224, and an unlocking element 226. The unlocking element 226 is connected to the first rack 213. The first mounting member 224 is installed in the housing 27. The first mounting member 224 is provided with a first guide rail 2241. The needle slider 221 and the thread slider 222 are respectively movably connected to the first guide rail 2241. The needle slider 221 is linked to the puncture needle assembly 11, and the thread slider 222 is linked to the stapler thread assembly 12. Figure 3 、 Figure 4 、 Figure 5 、 Figure 8 and Figure 10 As shown, the first mounting member 224 is provided with a first locking structure 2242 and a second locking structure 2243 sequentially distributed along the first direction a, and the unlocking element 226 is provided with a first unlocking structure 2261 and a second unlocking structure 2262 sequentially distributed along the first direction a.

[0111] When using the staple bundle implantation device 100 , the implantation end of the implantation cartridge 1 is first inserted into the proximal side of the prostate bundle. Then, the user controls the implantation cartridge 1 to perform needle insertion, needle retraction, and thread retraction by operating the main body 2 .

[0112] Specifically, if Figure 4 and Figure 6As shown, when the staple implantation device 100 is in the initial state, the actuating mechanism 22 and the implantation box 1 are both in the initial state, the first locking structure 2242 locks the needle sliding member 221, and the clamping and cutting assembly 13 is in the locked state. Figure 1 、 Figure 8 、 Figure 9 、 Figure 11 and Figure 12 As shown, when the puncture needle is triggered, the first motor 211 rotates forward, and under the meshing transmission of the first gear 212 and the first rack 213, the first gear 212 drives the first rack 213 to move linearly along the first direction a, and the first rack 213 drives the unlocking element 226 to move along the first direction a, and the first unlocking structure 2261 moves to unlock the first locking structure 2242. In this way, the actuating mechanism 22 can move from the initial position along the first direction a to the puncture completion position under external force, wherein the needle slider 221 drives the puncture needle assembly 11 to move, and the wire slider 222 drives the staple line assembly 12 to move, thereby achieving puncture of the prostate. At this time, the puncture needle 112 together with the distal anchor 113 passes through the prostate, that is, the distal anchor 113 and the staple line 122 are transported to the distal side of the prostate by the puncture needle 112.

[0113] like Figure 12 As shown, when the puncture needle assembly 11 completes the needle insertion, the second locking structure 2243 does not lock the thread slider 222. When the needle is withdrawn, the first motor 211 reverses. Under the meshing transmission of the first gear 212 and the first rack 213, the first gear 212 drives the first rack 213 to move linearly in the opposite direction. The first rack 213 drives the needle slider 221 and the unlocking element 226 to move in the second direction b. The thread slider 222 moves slightly in the second direction b and is then locked by the second locking structure 2243. That is, in the initial stage of needle withdrawal, the second locking structure 2243 locks the thread slider 222. Of course, the second locking structure 2243 can also lock the thread slider 222 while the needle is inserted. This solution places strict requirements on the assembly tolerance of the components. Therefore, preferably, locking is performed at the initial stage of needle closing, and the gap between the second locking structure 2243 and the locked portion of the thread slider 222 is configured to be 1mm-2mm, leaving a gap for assembly processing. At the same time, the thread slider 222 can also be locked at the moment of needle closing. For ease of explanation, the following description will use the example of "the second locking structure 2243 locking the thread slider 222 when needle closing is triggered" as an example.

[0114] like Figure 1 、 Figure 8 、 Figure 9 、 Figure 12 and Figure 14As shown, when the needle is retracted, the first motor 211 is reversed, and under the meshing transmission of the first gear 212 and the first rack 213, the first gear 212 drives the first rack 213 to move linearly in the opposite direction, and the first rack 213 drives the needle slider 221 and the unlocking element 226 to move along the second direction b, wherein the needle slider 221 drives the puncture needle assembly 11 to move along the second direction b, so that the puncture needle 112 is retracted from the prostate. Since the wire slider 222 is locked, the wire slider 222 is fixed. At this time, the distal anchor 113 remains on the distal side of the prostate, and one end of the staple line 122 passes through the prostate. After the puncture needle 112 is retracted from the prostate, the first rack 213 continues to move linearly, and the needle slider 221 continues to move in the second direction b to drive the puncture needle assembly 11 to its initial position. Furthermore, the unlocking element 226 moves in the second direction b until the second unlocking structure 2262 contacts the second locking structure 2243, thereby unlocking the second locking structure 2243. Then, under external force, the wire slider 222 can move in the second direction b to tighten the staple wire assembly 12, executing the wire retraction. By tightening the staple wire 122, the distal end stretches and compresses the distal side of the prostate. The first direction a and the second direction b are opposite.

[0115] When the line is taken up, the clamping and cutting are triggered, such as Figure 7 、 Figure 8 and Figure 16 As shown, the second motor 241 is turned on, and the second rack 243 provides power by moving linearly, and the power can be used to unlock the clamping and cutting assembly 13. After the clamping and cutting assembly 13 is unlocked, the proximal anchor 131 and the cutter 132 can both move, that is, the proximal anchor 131 moves at the proximal end of the prostate to clamp the staple line 122, and then the cutter 132 moves to cut the staple line 122, so that the proximal anchor 131 remains on the proximal side of the prostate, and under the tension of the staple line 122 retained in the prostate, the proximal anchor 131 squeezes the proximal side of the prostate, and the distal anchor 113 squeezes the distal side of the prostate, thereby shrinking the prostate and expanding the urethra.

[0116] In the above-described technical solution, the stapler insertion device 100 is equipped with a first drive mechanism 21 and a second drive mechanism 4. The first motor 211, the first gear 212, and the first rack 213 cooperate to directly provide a linear driving force to trigger the insertion, needle retraction, and thread retraction. The second motor 241, the second gear 242, and the second rack 243 cooperate to trigger the clamping and cutting assembly 13 to disengage, thereby performing clamping and cutting, achieving intelligent stapler insertion. Furthermore, compared to the prior art scheme using a gear and cam, the linear motion stroke length of the first rack 213 in this solution is adjustable. A single movement of the first rack 213 in the second direction b driven by the first motor 211 can sequentially trigger the needle retraction and thread retraction, simplifying operation and improving stapler insertion efficiency. Furthermore, the first drive mechanism 21 operates smoothly and has a stable structure. Compared to the prior art scheme using a gear and cam, it reduces vibration and noise generated during staple insertion, is less susceptible to damage, and has a long service life.

[0117] In the above technical solution, the actuating mechanism 22 is optimized by directly providing a first locking structure 2242 and a second locking structure 2243 on the first mounting member 224, respectively for locking the needle slider 221 when the actuating mechanism 22 is in the initial state and for locking the thread slider 222 when acupuncture is completed. This eliminates the need for additional locking elements, thereby simplifying the structure of the operating body 2. By providing a first unlocking structure 2261 and a second unlocking structure 2262 on the unlocking element 226 for respectively unlocking the first locking structure 2242 and the second locking structure 2243, and by defining the first locking structure 2242 and the second locking structure 2243 to be sequentially arranged along the first direction a, and the first unlocking structure 2261 and the second unlocking structure 2262 to be sequentially arranged along the first direction a, the needle slider 221 and the thread slider 222 can be sequentially unlocked by a single, repeated linear movement of the unlocking element 226. This results in a simple unlocking structure and operating steps, making it easy to control.

[0118] It should be understood that, herein, "proximal" and "distal" are relative positions, wherein the proximal end of the prostate refers to the portion of the prostate tissue adjacent to the urethra, and the distal end of the prostate refers to the portion of the prostate tissue farther away.

[0119] It should be understood that when the staple implantation device 100 is in normal use, the front end of the staple implantation device 100 faces the patient. In this document, the direction from back to front is referred to as the "first direction a", the direction from front to back is referred to as the "second direction b", and the direction from bottom to top is referred to as the "third direction c". The "first direction a" and "second direction b" mentioned in this document are both referred to as Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 11The marking in the “third direction c” shall prevail. Figure 7 、 Figure 8 and Figure 11 The markings in the table shall prevail.

[0120] It should be understood that "needle retraction" herein refers to retracting the puncture needle 112 from the prostate. When the puncture needle 112 is retracted from the prostate, the thread can be retracted.

[0121] In one embodiment, if Figure 1 、 Figure 6 and Figure 7 As shown, the needle slider 221 and the thread slider 222 are both located on the side of the first mounting member 224 facing the implant box 1, and the unlocking element 226 is located on the side of the first mounting member 224 facing away from the implant box 1. The unlocking element 226 is used to be movably connected to the housing 27. The various components are arranged compactly, which is conducive to the miniaturized design of the operating body 2.

[0122] In one embodiment, if Figure 7 and Figure 24 As shown, the operating body 2 also includes a first switch 23, which is used to trigger the operation of the first drive mechanism 21. When the actuator 22 is in the initial state, the first switch 23 is operated once to trigger the stapler implantation device 100 to perform a needle insertion. Then, the first switch 23 is operated again to trigger the stapler implantation device 100 to perform a needle insertion and a thread retraction. In this solution, the user only needs to operate the first switch 23 twice to control the stapler implantation device 100 to perform a needle insertion, a needle retraction, and a thread retraction. Compared to the existing solution that requires three manual operations to achieve a needle insertion, a needle retraction, and a thread retraction, this solution eliminates one operation, reduces the difficulty and operation time of the stapler implantation operation, and improves the efficiency of the stapler implantation.

[0123] In one embodiment, if Figure 1 and Figure 2 As shown, the actuating mechanism 22 further includes a first elastic member 223, which is connected to the needle slider 221 and the wire slider 222 respectively. When the needle is withdrawn, the wire slider 222 is locked, and the first elastic member 223 is pulled by the moving needle slider 221 to store energy. Therefore, after the puncture needle 112 is withdrawn from the prostate, as shown in FIG. Figure 14 and Figure 15 As shown, the wire sliding member 222 moves along the second direction b under the elastic force of the first elastic member 223 to tighten the staple wire assembly 12 to achieve wire retraction.

[0124] In one embodiment, if Figure 1 As shown, the actuating mechanism 22 further includes a second elastic member 225, one end of the second elastic member 225 is connected to the first mounting member 224, and the other end is connected to the needle sliding member 221. Figure 8 and Figure 11 As shown, when the actuating mechanism 22 is in the initial state, the needle slider 221 is locked and the second elastic member 225 is in a stored energy state. During acupuncture, the first rack 213 linearly moves, and the first rack 213 drives the unlocking element 226 to move to unlock the needle slider 221. After the needle slider 221 is unlocked, the second elastic member 225 can release its elastic force, and the needle slider 221 moves along the first direction a to the acupuncture completion position under the elastic force of the second elastic member 225.

[0125] The operating body 2 of the present invention is only provided with two elastic members, wherein the first elastic member 223 provides power for executing the needle, and the second elastic member 225 provides power for executing the thread reeling. The locking and unlocking of the needle slider 221 and the thread slider 222 do not require additional elastic members, which can reduce parts and simplify the assembly process.

[0126] In one embodiment, if Figure 1 As shown, the second elastic member 225 is a tension spring, the first mounting member 224 is provided with a second mounting post 2246, and the needle slider 221 is provided with a hook portion 2215. The hook portion 2215 and the second mounting post 2246 are spaced apart along the first direction a. One end of the second elastic member 225 is hooked on the second mounting post 2246, and the other end is hooked on the hook portion 2215. When the actuating mechanism 22 is in the initial state, the second elastic member 225 is stretched. When the needle slider 221 is unlocked, the second elastic member 225 rebounds to pull the needle slider 221 to move along the first direction a.

[0127] In one embodiment, if Figure 1 and Figure 2 As shown, the first elastic member 223 is a coil spring, the needle slider 221 is provided with a first mounting post 2213, the thread slider 222 is provided with a clamping structure 2222, one end of the first elastic member 223 is wound around the first mounting post 2213 and the other end is clamped to the clamping structure 2222. Figure 14 As shown, when the needle slider 221 moves along the second direction b and the thread slider 222 is locked, the first elastic member 223 is stretched, as shown in FIG. Figure 15 As shown, when the wire sliding member 222 is unlocked, the first elastic member 223 retracts to drive the wire sliding member 222 to move along the second direction b.

[0128] In one embodiment, if Figures 1 to 4As shown, when the actuating mechanism 22 is in an initial state, the first locking structure 2242 is at least partially located on the path of the needle slider 221 in the first direction a. Thus, the first locking structure 2242 can prevent the needle slider 221 from moving in the first direction a, thereby achieving locking. When acupuncture is performed, the first unlocking structure 2261 forces the first locking structure 2242 to move away from the path of the needle slider 221 in the first direction a. The first locking structure 2242 gives way to achieve unlocking, thereby allowing the needle slider 221 to move in the first direction a under the elastic force of the second elastic member 225.

[0129] During the acupuncture process, the thread slider 222 moves along the first direction a with the needle slider 221. When the puncture needle assembly 11 completes the acupuncture, both the needle slider 221 and the thread slider 222 stop moving. At this time, the second locking structure 2243 is at least partially located on the travel path of the thread slider 222 in the second direction b. In this way, in the initial stage of needle retraction, the second locking structure 2243 can prevent the thread slider 222 from moving along the second direction b. The thread slider 222 is locked and does not move along the second direction b with the needle slider 221, so that the needle retraction can be performed first and the puncture needle 112 can be retracted from the prostate. After the puncture needle 112 is retracted from the prostate, the second unlocking structure 2262 forces the second locking structure 2243 to give way and unlock, so that the thread slider 222 moves along the second direction b under the elastic force of the first elastic member 223 to achieve thread retraction.

[0130] Furthermore, if Figures 1 to 4 As shown, when the actuating mechanism 22 is in the initial state, the needle slider 221 is locked along the first direction a by at least partially contacting the first locking structure 2242. In the initial stage of needle collection, the thread slider 222 is locked along the second direction b by at least partially contacting the second locking structure 2243.

[0131] In one embodiment, if Figures 2 to 6As shown, the first locking structure 2242 includes a first connecting arm 22421, a first stop 22422, and a first extending arm 22423. One end of the first connecting arm 22421 is free, and the other end is fixed to the body of the first mounting member 224. The first stop 22422 and the first extending arm 22423 are respectively connected to the free end of the first connecting arm 22421. When the actuating mechanism 22 is in an initial state, the needle slider 221 is locked by at least partially abutting the first stop 22422 along the first direction a. The first extending arm 22423 is at least partially located along the travel path of the first unlocking structure 2261 in the first direction a. It should be understood that at this time, the force applied by the second elastic member 225 on the needle slider 221 is insufficient for the needle slider 221 to overcome the blocking force of the first stop 22422, thereby ensuring locking stability. During acupuncture, as the unlocking element 226 moves along the first direction a, the first unlocking structure 2261 moves to contact and squeeze the first extension arm 22423, deforming the first connecting arm 22421. This in turn causes the first stop 22422 to shift and disengage from the needle slider 221, thereby achieving unlocking. Furthermore, the needle slider 221 is provided with a first protrusion 22111, which abuts against the first stop 22422 along the first direction a, thereby being locked.

[0132] The second locking structure 2243 includes a second connecting arm 22431, a second stopper 22432 and a second extension arm 22433. One end of the second connecting arm 22431 is a free end and the other end is fixed to the body of the first mounting member 224. The second stopper 22432 and the second extension arm 22433 are respectively connected to the free end of the second connecting arm 22431. Figure 13 and Figure 14 As shown, in the initial stage of needle closing, the thread slider 222 is at least partially in contact with the second stop portion 22432 along the second direction b and is locked, and the second extension arm 22433 is at least partially located on the travel path of the second unlocking structure 2262 in the second direction b. It should be understood that at this time, the force exerted by the first elastic member 223 on the thread slider 222 is not enough to enable the thread slider 222 to overcome the blocking force of the second stop portion 22432. Figure 4 、 Figure 6 、 Figure 14 and Figure 15As shown, during the process of continuing to close the needle, when the unlocking element 226 moves along with the first rack 213 in the second direction b, the second unlocking structure 2262 moves to contact and squeeze the second extension arm 22433, so that the second connecting arm 22431 is deformed, and then the second stopper 22432 is displaced and separated from the thread slider 222, thereby achieving unlocking. After being unlocked, the thread slider 222 moves along the second direction b to close the thread. Figure 4 and Figure 13 As shown, the wire sliding member 222 is provided with a second protrusion 22211 , and the second protrusion 22211 abuts against the second stopping portion 22432 along the second direction b and is locked.

[0133] In the above scheme, a first protrusion 22111 is set on the needle sliding member 221, and a second protrusion 22211 is set on the wire sliding member 222, which can respectively cooperate with the first locking structure 2242 and the second locking structure 2243 to achieve corresponding locking. The locking structure is simple. In addition, by optimizing the first locking structure 2242 and the second locking structure 2243, unlocking is smoother.

[0134] Furthermore, if Figures 2 to 5 As shown, the first mounting member 224 is provided with a first hollow portion 22471 and a second hollow portion 22472, which are sequentially arranged along a first direction a. The first hollow portion 22471 and the second hollow portion 22472 are connected by a connecting portion 22473. A first connecting arm 22421 is located in the first hollow portion 22471 and its fixed end is connected to the connecting portion 22473. A first extending arm 22423 extends toward the unlocking element 226 and out of the first hollow portion 22471. A second connecting arm 22431 is located in the second hollow portion 22472 and its fixed end is connected to the connecting portion 22473. A second extending arm 22433 extends toward the unlocking element 226 and out of the second hollow portion 22472. In this embodiment, the first locking structure 2242 and the second locking structure 2243 are compactly arranged and both are connected to the main body of the first mounting member 224 via the connecting portion 22473, resulting in a simple structure and easy processing.

[0135] In one embodiment, if Figure 1 and Figure 23 As shown, when the actuator 22 moves to the full needle insertion position, the thread slider 222 abuts against the second mounting post 2246, stopping the actuator 22. In other words, the second mounting post 2246 also serves to limit the movement limit of the actuator 22 in the first direction a. When the actuator 22 is in the full needle insertion position, the distance between the second protrusion 22211 and the second stop 22432 is 1 mm to 2 mm.

[0136] In one embodiment, if Figure 1and Figure 4 As shown, the first locking structure 2242 and the second locking structure 2243 are located above the first guide rail 2241. The first protrusion 22111 is provided on the top wall of the needle slider 221, and the second protrusion 22211 is provided on the top wall of the thread slider 222. The first stop 22422 and the first protrusion 22111 are positioned opposite each other in the first direction a, and the second stop 22432 and the second protrusion 22211 are positioned opposite each other in the second direction b. The first locking structure 2242 and the second locking structure 2243 are arranged axially symmetrically, which facilitates a simplified structural design.

[0137] Furthermore, if Figures 4 to 6 、 Figure 11 As shown, the first stop portion 22422 includes a first stop surface 224221 and a first inclined surface 224222 sequentially distributed along the first direction a, and the first protrusion 22111 includes a first abutting surface 221111 and a second inclined surface 221112 sequentially distributed along the second direction b. The first stop surface 224221 and the first abutting surface 221111 are both perpendicular to the first direction a, and the first inclined surface 224222 extends obliquely in the first direction a away from the needle slider 221. When the actuating mechanism 22 is in an initial state, the first stop surface 224221 and the first abutting surface 221111 are stably abutted, and the second protrusion 22211 is located between the first locking structure 2242 and the second locking structure 2243, so that the second protrusion 22211 does not interfere with the first locking structure 2242. When the needle is inserted, the first protrusion 22111 is located between the first locking structure 2242 and the second locking structure 2243. In this way, when the needle is retracted, the needle slider 221 moves along the second direction b to the second inclined surface 221112 and abuts against the first inclined surface 224222. Since the two are inclined surfaces, under the drive of the first rack 213, the needle slider 221 can smoothly overcome the obstruction of the first inclined surface 224222, and the first protrusion 22111 smoothly passes over the first stop portion 22422 and is locked by the first stop portion 22422 again.

[0138] The second stop portion 22432 includes a second stop surface 224321 and a third inclined surface 224322 distributed in sequence along the second direction b, and the second protrusion portion 22211 includes a second abutting surface 222111 and a fourth inclined surface 222112 distributed in sequence along the first direction a. The second stop surface 224321 and the second abutting surface 222111 are both perpendicular to the second direction b, and the third inclined surface 224322 extends obliquely in the second direction b in the direction away from the offline sliding member 222. When acupuncture is performed, the wire slider 222 moves along with the needle slider 221 along the first direction a until the fourth inclined surface 222112 and the third inclined surface 224322 are in contact with each other. Since the two are inclined surfaces, the rebound force of the second elastic member 225 is sufficient to drive the wire slider 222 to overcome the obstruction of the third inclined surface 224322. The second protrusion 22211 smoothly passes over the second stop portion 22432 and continues to move along the first direction a. Moreover, when the actuator 22 reaches the acupuncture completion position, the first protrusion 22111 is located between the first locking structure 2242 and the second locking structure 2243, and the first protrusion 22111 will not interfere with the second locking structure 2243.

[0139] Furthermore, if Figure 4 As shown, there are two first protrusions 22111 and two second protrusions 22211. The two first protrusions 22111 are sequentially distributed along the first direction a, and the two second protrusions 22211 are sequentially distributed along the second direction b, to ensure the stability of the corresponding locking functions. It should be understood that when the first unlocking structure 2261 forces the first connecting arm 22421 to deform, both first protrusions 22111 can smoothly pass over the first stop 22422; and when the second unlocking structure 2262 forces the second connecting arm 22431 to deform, both second protrusions 22211 can smoothly pass over the second stop 22432.

[0140] In one embodiment, if Figure 3 and Figure 4 As shown, the first mounting member 224 is provided with a first through-hole 2244 extending in a first direction a. The needle slider 221 includes a first protrusion 2211, and the thread slider 222 includes a second protrusion 2221. The first protrusion 2211 is provided with a first protrusion 22111, and the second protrusion 2221 is provided with a second protrusion 22211. The first protrusion 2211 is movably inserted into the first through-hole 2244, so that the first protrusion 22111 can abut against the first locking structure 2242 in the first direction a, thereby locking the first protrusion. The second protrusion 2221 is movably inserted into the first through-hole 2244, so that the second protrusion 22211 can abut against the second locking structure 2243 in the second direction b, thereby locking the first protrusion. In this embodiment, the components of the actuator mechanism 22 are rationally and compactly arranged, facilitating the miniaturization of the operating body 2.

[0141] Furthermore, in order to facilitate the thin design of the first mounting member 224, as shown in FIG. Figure 3 and Figure 4 As shown, a groove 2248 is provided on the side of the first mounting member 224 facing away from the implantation box 1, and the groove 2248 is located above the first through hole 2244 and the two are connected. The first connecting arm 22421 and the second connecting arm 22431 are both located above the groove 2248, and the first stop portion 22422 and the second stop portion 22432 extend into the groove 2248. The first protrusion 22111 and the second protrusion 22211 are located in the groove 2248. The groove 2248 is used to accommodate part of the structure of the actuating mechanism 22, and the first protrusion 2211 and the second protrusion 2221 respectively abut against the groove wall of the groove 2248, which can prevent the needle slider 221 and the thread slider 222 from disengaging from the first guide rail 2241.

[0142] In one embodiment, if Figure 6 As shown, the first unlocking structure 2261 and the second unlocking structure 2262 are both protruding structures, which are simple in structure and easy to process.

[0143] In one embodiment, if Figure 3 and Figure 9 As shown, the needle slide 221 includes a third protrusion 2212, and the first rack 213 is provided with a boss 2131. When performing needle reduction, the boss 2131 can abut against the third protrusion 2212 along the second direction b, so that the first rack 213 drives the needle slide 221 to move along the second direction b to complete the needle reduction. Figure 2 and Figure 3 As shown, the first mounting member 224 defines a second through hole 2245 extending along the first direction a. The third protrusion 2212 is movably inserted into the second through hole 2245 , and the third protrusion 2212 partially extends out of the second through hole 2245 .

[0144] Furthermore, if Figure 6 and Figure 9As shown, when the actuating mechanism 22 is in the initial state, a gap is left between the boss 2131 and the third protrusion 2212 in the first direction a. In this way, when the actuating mechanism 22 moves along the first direction a under the rebound force of the second elastic member 225, the boss 2131 will not interfere with the movement of the third protrusion 2212, and will not hinder the needle sliding member 221 from moving along the first direction a to the needle completion position. In addition, when the needle is inserted, the first rack 213 drives the unlocking element 226 to move along the second direction b to the initial position of the unlocking element. At this time, the boss 2131 abuts against the third protrusion 2212 along the second direction b, or there is a gap between the boss 2131 and the third protrusion 2212 in the second direction b, for example, a gap of 1mm-2mm, to reserve a gap for the assembly process. In this way, when the needle needs to be retracted, the first rack 213 can immediately drive the needle slider 221 to move along the second direction b. At the same time, the unlocking element 226 located in its initial position also moves along the second direction b, so that after the puncture needle 112 is retracted from the prostate, the wire slider 222 is unlocked by the unlocking element 226.

[0145] In one embodiment, if Figures 1 to 3 As shown, a first guide rail 2241 is formed between the first through hole 2244 and the second through hole 2245, and the first protrusion 2211 and the third protrusion 2212 of the needle sliding member 221 are respectively inserted into the first through hole 2244 and the second through hole 2245, so that the needle sliding member 221 and the first guide rail 2241 can slide together. The various components of the actuating mechanism 22 are arranged compactly, which is conducive to the miniaturized design of the nail implantation device 100.

[0146] In one embodiment, if Figure 2 and Figure 3 As shown, the wire sliding member 222 is provided with a fourth protrusion 2224, the fourth protrusion 2224 is inserted into the second through hole 2245, and the outer end of the fourth protrusion 2224 forms a bent portion 22241, the bent portion 22241 abuts against the side wall of the first mounting member 224 away from the implant box 1, and, as shown Figure 4 As shown, the upper portion of the wire sliding member 222 abuts against the side wall of the first mounting member 224 away from the implantation box 1 through the second protrusion 22211, so that the wire sliding member 222 can stably slide with the first guide rail 2241.

[0147] In one embodiment, if Figure 1 and Figure 3As shown, the first mounting member 224 is provided with a first clamping portion 2249, and the bottom of the needle sliding member 221 is provided with a second clamping portion 2216. The top of the needle sliding member 221 is abutted against the groove wall of the groove 2248 through the first protrusion 2211, and the bottom of the needle sliding member 221 is movably clamped with the first clamping portion 2249 through the second clamping portion 2216, so that the needle sliding member 221 can stably slide with the first guide rail 2241.

[0148] In one embodiment, if Figure 1 As shown, the needle slider 221 and the thread slider 222 are distributed in sequence along the first direction a. When the actuating mechanism 22 is in the initial state, under the action of the first elastic member 223, the thread slider 222 abuts against the needle slider 221 along the second direction b. In this way, when acupuncture is performed, the needle slider 221 can drive the thread slider 222 to move along the first direction a.

[0149] In one embodiment, if Figure 1 and Figure 18 As shown, the needle slider 221 is provided with a first plug-in portion 2214, and the puncture needle assembly 11 includes a second plug-in portion 1111. The first plug-in portion 2214 and the second plug-in portion 1111 are plugged together to enable the needle slider 221 to be linked with the puncture needle assembly 11. The wire slider 222 is provided with a third plug-in portion 2223, and the staple wire assembly 12 includes a fourth plug-in portion 1211. The third plug-in portion 2223 and the fourth plug-in portion 1211 are plugged together to enable the wire slider 222 to be linked with the staple wire assembly 12. In one specific embodiment, the first plug-in portion 2214 and the third plug-in portion 2223 are both slot structures, and the second plug-in portion 1111 and the fourth plug-in portion 1211 are both snap-in protrusions, and the snap-in slots and snap-in protrusions are plugged together to achieve detachable assembly.

[0150] In one embodiment, if Figure 7 As shown, the implant box 1 and the operating body 2 are detachably connected, so that a new implant box 1 can be replaced for different patients to ensure hygiene. Of course, for the same patient, the implant box 1 can be replaced after several uses, or a new implant box 1 can be replaced each time.

[0151] In one embodiment, if Figure 9 and Figure 10 As shown, the first driving mechanism 21 includes a second guide rail 214 and a slider 215 that are slidably fitted. The second guide rail 214 is mounted on the inner wall of the housing 27 , and the first rack 213 and the unlocking element 226 are respectively connected to the slider 215 .

[0152] In one embodiment, the first gear 212 is provided with a first mounting hole (not shown in the figure). Figure 10As shown, the first output shaft 2111 is installed in the first mounting hole, and the cross section of the first output shaft 2111 is D-shaped. The cross section of the first mounting hole is D-shaped. The D-shaped shape can prevent misalignment between the first output shaft 2111 and the first mounting hole.

[0153] In one embodiment, during a complete use of the staple implantation device 100, the unlocking element 226 has five positions: an initial unlocking position, a first unlocking position, a first limit position, a second unlocking position, and a second limit position. Figure 6 and Figure 11 As shown, when the actuating mechanism 22 is in the initial state, the unlocking element 226 stops at the initial unlocking element position. When acupuncture is performed, the first rack 213 drives the unlocking element 226 to move along the first direction a to the position of unlocking the needle slider 221. At this time, the unlocking element 226 is in the first unlocking position. After the unlocking element 226 continues to move and releases the needle slider 221 from the lock, it continues to move along the first direction a to the first limit position and stops. Figure 12 As shown, after the needle slide 221 is unlocked, the actuator 22 moves to the complete needle position under the pull of the second elastic member 225. After the needle is completed, the unlocking element 226 returns to the initial position of the unlocking element and stops. Figures 13 to 15 As shown, the first rack 213 drives the unlocking element 226 and the needle slider 221 to move along the second direction b. When the unlocking element 226 moves to the second unlocking position, the unlocking element 226 unlocks the second unlocking structure 2243. In this way, under the elastic force of the first elastic member 223, the thread slider 222 moves along the second direction b until it abuts against the needle slider 221. Then, the needle slider 221 and the thread slider 222 return to the initial position of the actuating mechanism 22. At this time, as shown in FIG. Figure 15 As shown, the unlocking element 226 moves along the second direction b with the first rack 213 to the second limit position. Figure 11 As shown, the unlocking element 226 moves along the first direction a to return to the unlocking element initial position.

[0154] like Figure 9As shown, the unlocking element 226 is provided with a first blocking piece 2263 and a second blocking piece 2264 spaced apart along a first direction a, and the operating body 2 includes a first optical coupler 282, a second optical coupler 283, and a third optical coupler 284 spaced apart along the first direction a. When the unlocking element 226 is in the initial unlocking position, the second blocking piece 2264 and the second optical coupler 283 cooperate to obtain position information of the unlocking element 226. When the unlocking element 226 is in the first extreme position, the second blocking piece 2264 and the third optical coupler 284 cooperate to obtain position information of the unlocking element 226. When the unlocking element 226 is in the second extreme position, the first blocking piece 2263 and the first optical coupler 282 cooperate to obtain position information of the unlocking element 226.

[0155] In one embodiment, if Figure 8 and Figure 16 As shown, the operating body 2 further includes a trigger element 25, which is connected to the second rack 243. When clamping and cutting are performed, the second motor 241 rotates forward, and the second rack 243 drives the trigger element 25 to move toward the clamping and cutting assembly 13, so that the trigger element 25 moves into contact with the clamping and cutting assembly 13. In this way, the clamping and cutting assembly 13 is unlocked under the push of the trigger element 25.

[0156] Furthermore, if Figure 17 and Figure 18 As shown, the implant box 1 includes a second mounting member 14, and the clamping and cutting assembly 13 includes a proximal anchor actuator 133, a cutter actuator 134, a third elastic member 135, a first locking member 136 and a second locking member 137. The proximal anchor actuator 133 and the cutter actuator 134 are respectively movably mounted on the second mounting member 14, and both ends of the third elastic member 135 are respectively connected to the proximal anchor actuator 133 and the cutter actuator 134, and the first locking member 136 and the second locking member 137 are respectively rotatably connected to the second mounting member 14.

[0157] During the process of needle insertion, needle retraction and thread retraction of the staple implantation device 100, the clamping and cutting assembly 13 is always in the initial state. In this state, the first locking member 136 locks the proximal anchor actuator 133, the second locking member 137 locks the cutter actuator 134, the third elastic member 135 is in a tensioned state, and the first locking member 136 is at least partially located on the movement path of the trigger element 25.

[0158] After the staple bundle implantation device 100 has completed the needle insertion, needle retraction, and thread retraction, it begins to clamp and cut. Figure 8 and Figure 16As shown, under the drive of the second driving mechanism 24, the trigger element 25 moves until the trigger element 25 is released from the first locking member 136. Then, under the push of the trigger element 25, as shown in FIG. Figure 18 As shown, the first locking member 136 rotates and disengages from the proximal anchor member actuator 133, so that the proximal anchor member actuator 133 is unlocked. At the same time, the first locking member 136 contacts the second locking member 137 due to the rotation and pushes the second locking member 137 to rotate, and the second locking member 137 disengages from the cutter actuator 134 due to the rotation, so that the cutter actuator 134 is unlocked. Then, under the rebound force of the third elastic member 135, the proximal anchor member actuator 133 and the cutter actuator 134 move toward each other, so that the proximal anchor member 131 and the cutter 132 move toward each other, and the movement speed of the proximal anchor member actuator 133 is less than the speed of the cutter actuator 134, so that the V-shaped bayonet of the proximal anchor member 131 first clamps the staple line 122, and then the cutter 132 cuts the staple line 122 to achieve clamping and cutting.

[0159] Furthermore, if Figure 18 and Figure 23 As shown, the proximal anchor actuator 133, the second locking member 137 and the cutter actuator 134 are distributed in sequence along the first direction a, the bottom of the proximal anchor actuator 133 is provided with a first card groove 1331, the two sides of the first locking member 136 are respectively provided with a first card protrusion 1361 and a pushing portion 1362, the two sides of the second locking member 137 are respectively provided with a pushed portion 1371 and a first abutting portion 1372, and the cutter actuator 134 is provided with a second abutting portion 1341.

[0160] When the clamping and cutting assembly 13 is in its initial state, the first engaging protrusion 1361 engages upwardly within the first engaging groove 1331 to restrict movement of the proximal anchor actuator 133 in the first direction a. The pushing portion 1362 is positioned below the pushed portion 1371 with a gap therebetween. The first abutting portion 1372 abuts upwardly along the first direction a against the second abutting portion 1341 to restrict the proximal anchor actuator 133 and the cutter actuator 134 from moving toward each other under the pulling force of the third elastic member 135.

[0161] When the trigger element 25 moves upward, the trigger element 25 pushes the first locking member 136 upward near the pushing portion 13621, causing the first locking member 136 to rotate, and the first locking protrusion 1361 rotates downward and disengages from the first locking groove 1331, the proximal anchor actuator 133 is unlocked, the pushing portion 1362 rotates upward and pushes the pushed portion 1371 upward, causing the second locking member 137 to rotate, the first abutting portion 1372 rotates downward and disengages from the second abutting portion 1341, and the cutter actuator 134 is unlocked.

[0162] In one embodiment, if Figure 8 and Figure 16 As shown, the second rack 243 can move along the third direction c, the third direction c is perpendicular to the first direction a, and the output shafts of the first motor 211 and the second motor 241 are perpendicular to each other.

[0163] In one embodiment, if Figure 8 and Figure 24 As shown, the housing 27 of the operating body 2 includes a main body 272 and a handle 271 connected to each other. The first drive mechanism 21 and the second motor 241 are located in the main body 272. The trigger element 25 includes a trigger end 251 and a detected end 252. The trigger end 251 is located in the main body 272 and is used to unlock the clamping and cutting assembly 13. The detected end 252 is at least partially located in the handle 271 and is used to connect to the travel switch trigger element 281. The space in the handle 271 is used to accommodate the trigger element 25, and the structure is more compact.

[0164] During a complete use of the staple implantation device 100, the trigger element 25 has two positions: the initial position of the trigger element and the trigger unlocking position of the trigger element. Figure 16 As shown, the operating body 2 also includes a first travel switch 285 and a second travel switch 286. When the clamping and cutting assembly 13 is in the initial state, the trigger element 25 is in the initial position of the trigger element, and the first travel switch 285 cooperates with the travel switch trigger element 281 to obtain the position information of the trigger element 25; when the trigger element 25 moves to the position of unlocking the first locking member 136, the trigger element 25 is in the trigger element trigger unlocking position, and the second travel switch 286 cooperates with the travel switch trigger element 281 to obtain the position information of the trigger element 25.

[0165] In one embodiment, if Figure 16 As shown, the second drive mechanism 24 includes a guide rod 244 mounted on the inner wall of the housing 27. The second rack 243 is movably connected to the guide rod 244. A gap is left between the guide rod 244 and the inner wall of the housing 27. The second gear 242 is located in the space between the guide rod 244 and the inner wall of the housing 27, fully utilizing the lateral space within the housing 27.

[0166] The second gear 242 is provided with a second mounting hole (not shown in the figure), such as Figure 16 As shown, the second output shaft 2411 is installed in the second mounting hole, and the cross section of the second output shaft 2411 is D-shaped, and the cross section of the second mounting hole is D-shaped. The D-shaped shape can prevent the second output shaft 2411 from being misaligned with the second mounting hole.

[0167] In one embodiment, if Figure 7 and Figure 24As shown, the operating body 2 also includes a second switch 26. When the prostate stapler implantation device 100 is powered off, operating the second switch 26 once activates the prostate stapler implantation device 100 and automatically calibrates the device 100 to its initial state to ensure the device's accuracy during long-term use. After automatic calibration, the device then performs the needle insertion, needle and thread retraction, clamping, and cutting operations. Of course, the prostate stapler implantation device 100 can also be configured without an automatic calibration function, with the accuracy of the device 100 ensured throughout its useful life by limiting the number of uses. It should be understood that after operating the second switch 26 once to activate the prostate stapler implantation device 100, multiple stapling operations can be performed continuously without the need for automatic calibration again. Automatic calibration is only performed when the device is shut down and restarted.

[0168] Specifically, if the needle slider 221 and the thread slider 222 are not in their initial positions, when automatic calibration is performed, the first motor 211 operates to drive the needle slider 221 and the thread slider 222 to move along the first direction a to restore to their initial positions, completing the automatic calibration.

[0169] In one embodiment, if Figure 7 and Figure 24 As shown, the first switch 23 is also used to trigger the operation of the second drive mechanism 24. The first switch 23 controls the actuation of clamping and cutting, preventing the user from accidentally triggering clamping and cutting due to operational errors. Specifically, after the staple bundle implantation device 100 is activated, the first switch 23 is operated once to trigger the needle insertion, then again to trigger needle and thread retraction, and then again to trigger clamping and cutting. Through these three operations of the first switch 23, the execution of the needle insertion, needle and thread retraction, clamping, and cutting can be controlled sequentially.

[0170] Furthermore, if Figure 7 and Figure 24 As shown, the first switch 23 is arranged on the front side of the handle 271, and the second switch 26 is arranged on the rear side of the housing 27 and above the handle 271. The two trigger switches are arranged in opposite positions, which can improve the safety of the operation of the two trigger switches.

[0171] In one embodiment, if Figure 24 As shown, the first switch 23 is a push button switch, which is more convenient to use and less likely to be accidentally triggered than the plate switch in the prior art. The second switch 26 is a rocker switch, which has a different structure from the first switch 23 and serves as a difference reminder to prevent users from operating the wrong switch.

[0172] In one embodiment, if Figure 7 As shown, the staple implantation device 100 includes a battery 292 for powering the device. The battery 292 is placed in the handle 271 of the housing 27 .

[0173] In one embodiment, if Figure 7 As shown, the housing 27 includes a first shell 273 and a second shell 274. The first shell 273 and the second shell 274 together enclose a cavity, and the first drive mechanism 21, the actuating mechanism 22, the second drive mechanism 24 and the trigger element 25 are all located in the cavity. Figure 7 and Figure 17 As shown, the implant cartridge 1 includes an outer cover 16, a base 17, and a locking knob 18. The outer cover 16 and the base 17 are connected and together clamp the second mounting member 14. The locking knob 18 is provided on the outer cover 16. The implant cartridge 1 is detachably mounted on the first housing 273 and locked by the locking knob 18. The first drive mechanism 21 and the second drive mechanism 24 are mounted on the inner wall of the second housing 274. The assembly of the implant cartridge 1 and the housing 27 can refer to the assembly structure and principle of any existing stapler binding device.

[0174] In one embodiment, if Figure 7 As shown, the operating body 2 further includes an endoscope sheath 291 , one end of which is located in the housing 27 and mounted on the first mounting member 224 , and the other end of which extends to the outside of the housing 27 .

[0175] In one embodiment, if Figure 24 As shown, the implantation box 1 also includes an indicator light 293, which is set on the shell 27. The indicator light 293 is used to indicate the current state of the staple implantation device 100, including the automatic calibration completion state, the needle insertion completion state, the needle and thread collection completion state, and the clamping and cutting completion state.

[0176] Furthermore, in one embodiment, the number of the indicator light 293 may be one, which indicates the above four states respectively by displaying lights of different colors or different flashing frequencies.

[0177] In another embodiment, Figure 23 As shown, the number of indicator lights 293 can be four, and the four indicator lights 293 at different positions can be turned on or off to indicate the above four states respectively. For example, the four indicator lights 293 are spaced apart along the first direction a. When the automatic calibration of the staple implantation device 100 is completed, the first indicator light 293 located in the first direction a lights up; when the staple implantation device 100 has completed needle insertion, the second indicator light 293 located in the first direction a lights up; when the staple implantation device 100 has completed needle and thread retraction, the third indicator light 293 located in the first direction a lights up; when the staple implantation device 100 has completed clamping and cutting, the fourth indicator light 293 located in the first direction a lights up. The prompts of the indicator lights 293 make human-computer interaction more convenient, make the staple operation process clearer, and make it safer to use.

[0178] In one embodiment, if Figures 18 to 21 As shown, the puncture needle assembly 11 also includes a connected puncture needle connector 111 and a puncture needle guide tube 114. The puncture needle connector 111 has a second plug-in portion 1111, which plugs into the first plug-in portion 2214 of the needle slider 221. The staple line assembly 12 also includes a staple line connector 121, a staple line guide tube 123, and a staple line support tube 124. The staple line connector 121 has a fourth plug-in portion 1211, which plugs into the third plug-in portion 2223 of the line slider 222. The puncture needle guide tube 114, the staple line guide tube 123, and the staple line support tube 124 all have hollow structures. One end of the puncture needle guide tube 114 is connected to the puncture needle connector 111, and one end of the puncture needle 112 is inserted into the puncture needle guide tube 114. The staple line guide tube 123 is located inside the puncture needle guide tube 114 and the two are clearance-fitted. One end of the staple line support tube 124 is inserted into the staple line guide tube 123 and connected to one end of the staple line 122 , and the other end is connected to the staple line connector 121 .

[0179] In one embodiment, if Figures 18 to 20 、 Figure 22 As shown, the clamping and cutting assembly 13 further includes a push rod 138 and a pull rod 139. The pull rod 139 has a hollow structure. One end of the push rod 138 is connected to the proximal anchor actuator 133, and the other end is movably inserted into the pull rod 139. This end abuts the proximal anchor 131 along the first direction a. One end of the pull rod 139 is connected to the cutter actuator 134, and the other end is connected to the cutter 132. When the proximal anchor actuator 133 and the cutter actuator 134 move toward each other, the proximal anchor actuator 133 moves in the first direction a, and the cutter actuator 134 moves in the second direction b. In this way, the push rod 138 pushes the proximal anchor 131 away from the first direction a, and the pull rod 139 pulls the cutter 132 along the second direction b, thereby achieving clamping and cutting. It should be understood that the specific details of the proximal anchor actuator 133 and the cutter actuator 134 moving toward each other to achieve clamping and cutting can be referred to the principle and structure of any existing staple bundle device.

[0180] In one embodiment, the implant box 1 further includes a gun tip welding assembly 15 , the specific structure and principle of which can refer to any existing nail binding device.

[0181] Specifically, the complete operation steps of the staple bundle implantation device 100 of this solution are as follows:

[0182] (1) Power on and automatic calibration

[0183] The user operates the second switch 26 once to turn on the staple implantation device 100, and the staple implantation device 100 performs automatic calibration so that the staple implantation device 100 is in an initial state. At this time, the first protrusion 22111 of the needle sliding member 221 abuts against the first stop portion 22422 along the first direction a and is locked, and the second elastic member 225 is compressed.

[0184] (2) Needle

[0185] Before acupuncture, the user first moves the front end of the implant box 1 to the proximal side of the prostate. Then, the user operates the first switch 23 for the first time, the first motor 211 rotates forward, and drives the unlocking element 226 to move along the first direction a through the first rack 213. When the unlocking element 226 moves to the first unlocking structure 2261 and contacts and squeezes the first extension arm 22423, the first connecting arm 22421 is deformed, thereby causing the first stop portion 22422 to disengage from the first protrusion 22111, and the needle slider 221 is unlocked. Then, the second elastic member 225 rebounds instantaneously to push the needle slider. 221 moves together with the wire slider 222 along the first direction a, wherein the needle slider 221 drives the puncture needle assembly 11 to move along the first direction a, and the wire slider 222 drives the staple wire assembly 12 to move along the first direction a. The puncture needle 112 passes through the prostate to transport the distal anchor 113 located in the puncture needle 112 to the distal side of the prostate. One end of the staple wire 122 is located in the puncture needle 112 and is connected to the distal anchor 113 to complete the puncture. At this time, the second protrusion 22211 of the wire slider 222 and the second locking structure 2243 are distributed sequentially along the second direction b and are 2 mm apart.

[0186] Then, the first rack 213 drives the unlocking element 226 to move along the second direction b. Since there is a certain distance between the boss 2131 of the first rack 213 and the third protrusion 2212 in the second direction b, the needle sliding member 221 does not move under the constraint of the second elastic member 225. When the unlocking element 226 moves to the initial position of the unlocking element, the first motor 211 stops running. At this time, the boss 2131 and the third protrusion 2212 are 2 mm apart in the second direction b.

[0187] (3) Needle and thread closing

[0188] The user operates the first switch 23 for the second time, the first motor 211 reverses, driving the first rack 213 and the unlocking element 226 to move along the second direction b, and the boss 2131 of the first rack 213 pushes the needle slider 221 to move along the second direction b. Under the pull of the first elastic member 223, the wire slider 222 moves along the second direction b with the needle slider 221. When it moves 2 mm, the second protrusion 222111 of the wire slider 222 abuts against the second stop portion 22432 along the second direction b and is locked.

[0189] The first motor 211 continues to reverse, continuing to drive the first rack 213 and the unlocking element 226 to move along the second direction b, and the boss 2131 of the first rack 213 continues to push the needle slider 221 to move along the second direction b. In this way, the needle slider 221 drives the puncture needle assembly 11 to move along the second direction b, so that the puncture needle 112 is retracted from the prostate, and the distal anchor 113 remains on the distal side of the prostate, thereby achieving needle retraction. In addition, since the wire slider 222 is locked by the second stop portion 22432 on the first mounting member 224, the first elastic member 223 is stretched. During the needle retraction process, when the unlocking element 226 moves to the second unlocking structure 2262 and contacts the second extension arm 22433 and squeezes the second extension arm 22433, the second connecting arm 22431 is deformed, thereby causing the second stop portion 22432 to disengage from the thread slider 222, and the thread slider 222 is unlocked. Then, the first elastic member 223 retracts instantaneously to pull the thread slider 222 to move along the second direction b until it contacts the needle slider 221 again, and in the first elastic member 223, the thread slider 222 is retracted. Under the pull of the member 223 and the drive of the first rack 213, the wire slider 222 moves to the extreme position along the second direction b together with the needle slider 221 to complete the wire winding. By tightening the staple line 122 to stretch the distal end and squeeze the distal side of the prostate, at this time, the first protrusion 22111 of the needle slider 221 and the first stop portion 22422 of the first locking structure 2242 are distributed in sequence along the first direction a and the gap between the two is 2 mm, which is the reserved assembly process gap.

[0190] Then, the first rack 213 drives the unlocking element 226 to move 2 mm in the first direction a. The needle slider 221 and the thread slider 222, pulled by the second elastic member 225, simultaneously move 2 mm in the first direction a, causing the first protrusion 22111 to abut against the first stop 22422, and the needle slider 221 is re-locked by the first locking structure 2242. The first rack 213 continues to drive the unlocking element 226 in the first direction a to its initial position, and the first motor 211 stops.

[0191] (4) Clamping and cutting

[0192] The user first adjusts the angle between the staple line 122 and the prostate through the endoscope of the staple implantation device 100, and compresses the prostate through the gun tip welding assembly 15 of the implantation box 1 to shrink the prostate. Then, the user operates the first switch 23 for the third time, and the second motor 241 runs, driving the trigger element 25 to move in the direction of the first locking member 136 of the clamping and cutting assembly 13. The trigger element 25 pushes the first locking member 136 to rotate and unlock the proximal anchor actuator 133. The first locking member 136 pushes the second locking member 137 to rotate and unlock the cutter actuator 134. Then, under the rebound force of the third elastic member 135, the proximal anchor actuator 133 and the cutter actuator 134 move toward each other to achieve clamping and cutting.

[0193] Then, the user releases the prostate tissue, the prostate tissue rebounds, and the proximal anchor 131 and the distal anchor 113 are tensioned outward. The proximal anchor 131 and the distal anchor 113 compress the tissue from both ends of the prostate respectively, completing the pinning, and withdrawing the implantation box 1. After replacing the implantation mechanism 1, a new pinning implantation operation can be repeated.

[0194] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations of the claims. Various modifications and variations may be made to the above embodiments without departing from the scope of the present disclosure. Similarly, the various technical features of the above embodiments may be arbitrarily combined to form additional embodiments of the present invention that may not be explicitly described.
