Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an anchoring piece delivery system and a handle and a magazine thereof. Background Art

[0002] Benign prostatic hyperplasia (BPH) is one of the most common medical conditions affecting men, particularly older men. The prostate gland continues to enlarge throughout life. In some men, the prostatic capsule surrounding the prostate may prevent further enlargement. This can cause the inner area of the prostate to press against the urethra. This pressure on the urethra increases the resistance to urine flow through the area of the urethra surrounded by the prostate. Consequently, the bladder must exert greater pressure to force urine through the increased urethral resistance. Chronic overexertion can cause the bladder's muscle wall to remodel and become stiffer. This increased urethral resistance and increased urine flow hardness, along with bladder wall hypertrophy, can lead to various lower urinary tract symptoms (LUTS), which can significantly reduce a patient's quality of life. These symptoms include a weak or intermittent urine stream during urination, straining during urination, hesitation before starting urination, a feeling that the bladder is not completely empty even after urination, dribbling or leaking at the end of urination, increased urination frequency, especially at night, and urgency. In addition to men with BPH, LUTS can also be present in patients with prostate cancer, prostate infections, and long-term use of certain medications that cause urinary retention. Although BPH is rarely life-threatening, it can lead to numerous clinical complications, including urinary retention, renal insufficiency, recurrent urinary tract infections, incontinence, hematuria, and bladder stones.

[0003] Currently, the treatment options available for BPH include watchful waiting, medical therapy (herbal remedies and prescription drugs), surgery, and minimally invasive surgery. Surgical procedures used to treat BPH symptoms include transurethral resection of the prostate (TURP), transurethral electrovaporization of the prostate (TVP), transurethral incision of the prostate (TUIP), laser prostatectomy, and open prostatectomy. Minimally invasive procedures used to treat BPH symptoms include transurethral microwave thermotherapy (TUMT), transurethral needle ablation (TUNA), interstitial laser coagulation (ILC), and prostate stents.

[0004] Many current treatments for BPH carry a high risk of side effects. These methods and devices either require general or spinal anesthesia or, with their potential side effects, require surgery in a surgical suite and subsequent hospitalization. BPH treatments with a lower risk of adverse effects are also associated with lower reductions in symptom scores. While some of these procedures can administer local analgesia in an office setting, patients do not experience immediate relief and, in fact, often experience worsening symptoms for several weeks after surgery as the body begins to heal. Furthermore, many device approaches require the placement of a catheter in the bladder, in some cases for several weeks. In some cases, catheterization is necessary because the treatment can actually cause an obstruction for some time after surgery, while in other cases, it is necessary due to postoperative bleeding and the potential for occlusive clot formation. While drug therapies are easy to administer, the results are less than ideal, they take a significant amount of time to be effective, and they often produce undesirable side effects.

[0005] Prostate suspension surgery is a minimally invasive procedure that uses a transurethral implant to dilate the obstructed prostatic urethra. The principle is to suspend and compress the obstructed lateral lobe of the prostate by implanting a miniature urethral suspension device, thereby dilating the obstructed prostate urethra and improving the patient's obstruction symptoms. However, existing surgical instruments used for prostate suspension surgery have the following drawbacks:

[0006] 1. The puncture length cannot be adjusted and the puncture needle length is fixed, which causes greater damage and higher risks for patients with small glands.

[0007] 2. The structure is complex and there are many operating steps, which may easily lead to doctor's misoperation.

[0008] 3. There is no convenient instrument reset function. When the structure becomes stuck and fails, the internal structure cannot be easily reset, which increases the risk of surgery. Summary of the Invention

[0009] In order to solve the above technical problems, one of the purposes of the present invention is to provide an anchoring member delivery system, which has a more reasonable and simple structure and action, is easy to operate and not prone to errors, has better reliability, facilitates surgical operations, and reduces the risk of surgical errors.

[0010] A second object of the present invention is to provide a magazine for the above-mentioned anchor delivery system.

[0011] A third object of the present invention is to provide a handle for the above-mentioned anchor delivery system.

[0012] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0013] A magazine for an anchor delivery system, comprising: a puncture needle tube, a puncture needle capable of moving back and forth is inserted into the puncture needle tube, a suture capable of moving back and forth is inserted into the puncture needle, and the proximal end of the puncture needle tube is fixedly connected to the front end of the magazine body; a push-pull tube, a shearing rod and a pushing rod capable of moving back and forth are inserted into the push-pull tube, and the proximal end of the push-pull tube is fixedly connected to the front end of the magazine body; a puncture needle connector, the puncture needle connector is mounted in the magazine body in a manner that allows it to slide back and forth, and the front portion of the puncture needle connector is fixedly connected to the proximal end of the puncture needle; a shearing component, the shearing component is mounted in the magazine body in a manner that allows it to slide back and forth, and the shearing component The blade is pulled backward by the shear rod to complete the action of cutting the suture; a pushing component is installed in the magazine body in a manner that it can slide back and forth, and the pushing component pushes the proximal anchor forward through the pushing rod; the shearing component and the pushing component are arranged front to back and are connected by a tension spring to pull the two toward each other; a support component is installed between the shearing component and the pushing component, and the support component has two position states: when the support component is in the first position, it limits the backward movement of the shearing component, and does not limit the pushing component; when the support component is in the second position, it limits the forward movement of the pushing component, and does not limit the shearing component.

[0014] Preferably, the proximal end of the suture is fixedly connected to the suture fixing seat, the suture fixing seat is mounted on the puncture needle connector in a manner that allows it to slide back and forth, and the distal end of the suture is fixedly connected to the distal anchor; a guide rod passes through the puncture needle connector, and the guide rod is provided with a suture reset spring for giving the suture fixing seat a tendency to move backward, the suture fixing seat is sleeved on the guide rod, one end of the spring is against the suture fixing seat, and the other end of the suture reset spring is against the puncture needle connector.

[0015] Preferably, a suture reset pin that can move up and down is provided in the magazine body, and a pin reset spring is provided on the suture reset pin. One end of the pin reset spring is against the magazine, and the other end of the pin reset spring is against the suture reset pin, so that the pin reset spring can generate downward pressure on the suture reset pin, and the lower end of the suture reset pin can cooperate with the slot limit on the suture fixing seat to limit the backward movement of the suture fixing seat. The puncture needle connector is provided with a slope that can prompt the suture reset pin to move upward, thereby prompting the suture reset pin to disengage from the limit cooperation with the suture fixing seat.

[0016] Preferably, a retaining ring is fixed on the suture reset pin, which abuts against the pin reset spring so that the pin reset spring can exert downward pressure on the suture reset pin, and the retaining ring can abut against the magazine to limit the range of downward movement of the suture reset pin.

[0017] Preferably, the magazine further includes a push locking member disposed within the magazine body, which is connected to the push component when the push locking member is in an initial position, such that the push component is locked and cannot be moved.

[0018] Preferably, the push locking member is rotatably arranged in the magazine body, and the push locking member has a hook portion, which cooperates with the clamping portion on the pushing component to realize limit locking; the push locking member has a release portion, and the shear trigger rod on the handle pushes the release portion to realize the rotation of the push locking member and thereby unlock the pushing component.

[0019] A handle for an anchor delivery system, for use in conjunction with a magazine for an anchor delivery system as described above, comprising: a handle shell; an energy storage slider, the energy storage slider is arranged in the handle shell in a manner that can slide back and forth and is connected to the puncture needle connector in the magazine for synchronous movement, the energy storage slider is connected to the handle shell through an energy storage spring so that it is given a tendency to move forward, the energy storage slider is connected to the handle shell through a pawl mechanism so that it is restricted from moving forward, when the energy storage slider moves backward into position, the pawl mechanism fails, so that the energy storage slider moves forward rapidly under the action of the energy storage spring; a trigger component, the trigger component is arranged in the handle shell in a manner that can slide back and forth, the trigger component is given a tendency to move forward through the trigger spring, and the trigger component is connected to or disengaged from the energy storage slider through a clutch structure: when the trigger component is connected to the energy storage slider, it can drive the energy storage slider to move backward; when the trigger component moves backward into position, it disengages from the energy storage slider and cannot drive the energy storage slider to move.

[0020] Preferably, it also includes: a first knob, which is mounted in the handle housing in a deflectable manner. When the energy storage slider moves backward into position, the energy storage slider applies force to one foot of the first knob, causing the first knob to deflect, and the other foot of the first knob to move the locking slider, causing the locking slider to retract and disengage from the ratchet on the handle housing, thereby unlocking the energy storage slider from the handle housing; a second knob, which is mounted in the handle housing in a deflectable manner. When the trigger component moves backward into position, the trigger component applies force to one foot of the second knob, causing the second knob to deflect, and the other foot of the second knob to move the sliding push block on the trigger component, causing the sliding push block to disengage from the energy storage slider, thereby unlocking the energy storage slider from the trigger component.

[0021] Preferably, a shear trigger rod and an elastic limiter are provided. The shear trigger rod is mounted in the handle housing in a manner that allows it to slide up and down. The shear trigger rod is fixedly connected or integrally formed with a shear push button that is slidably arranged outside the handle housing. The elastic limiter is used to lock the shear trigger rod to prevent it from moving up and down. When the trigger component moves backward into position, it pushes the elastic limiter to unlock, so that the shear trigger rod can move up and down. The shear trigger rod releases the lock of the push locking component on the push component by pushing the release portion on the push locking component in the magazine body.

[0022] Preferably, the elastic limit member includes a limit bolt and a limit bolt spring. The limit bolt is connected to the handle housing through the limit bolt spring and can move and elastically reset. The limit bolt crosses the shear trigger rod. In the initial state, the limit bolt is under the action of the limit bolt spring. The large head of the limit bolt is placed inside the shear trigger rod, thereby limiting the shear trigger rod and preventing it from moving up and down. When the limit bolt is displaced backward by the force of the trigger component, the large head of the limit bolt leaves the inside of the shear trigger rod, and the shear trigger rod is unlocked at this time and can move upward.

[0023] An anchor delivery system comprises a magazine for an anchor delivery system as described above and a handle for an anchor delivery system as described above.

[0024] Due to the adoption of the above technical solutions, the utility model has more reasonable and simple structure and action, is easy and convenient to operate and is less prone to errors, has better reliability, facilitates surgical operations, and reduces the risk of surgical misoperation.

[0080] For the convenience of expression, the present invention Figure 1The left side is the front, the right side is the back, the top is the upper, and the bottom is the lower. The other two sides perpendicular to the front and back direction are divided into left and right. The surgical end of the instrument is the distal end, and the operating end of the instrument is the proximal end.

[0081] Example 1:

[0082] like Figure 1 An anchor delivery system shown includes a handle 100 and a magazine 200. The magazine 200 is mounted on the handle 100 in a detachable and replaceable manner. The handle 100 transfers its own stored mechanical energy to the magazine 200 to deliver the implant into the patient's body.

[0083] like Figure 3 The magazine 200 shown includes:

[0084] A puncture needle tube 224, in which a puncture needle 221 capable of moving back and forth is inserted, the proximal end of the puncture needle tube 224 is fixedly connected to the front end of the magazine body, and the distal end of the puncture needle tube 224 is fixedly connected to the head end component 222;

[0085] A push-pull tube 225, through which a shear rod 228 and a push rod 227 capable of moving back and forth are inserted, the proximal end of the push-pull tube 225 is fixedly connected to the front end of the magazine body, and a proximal anchor 400 capable of moving back and forth and being disengaged is provided in the distal opening of the push-pull tube 225, and the distal end of the push-pull tube 225 is fixedly connected to the head end component 222;

[0086] A puncture needle connector 208, the front portion of which is fixedly connected to the proximal end of a puncture needle 221. A suture 500 capable of moving back and forth is passed through the puncture needle 221. The proximal end of the suture 500 is fixedly connected to a suture holder 211. The suture holder 211 is mounted on the puncture needle connector 208 in a manner that allows it to slide back and forth. The distal end of the suture 500 is fixedly connected to the distal anchor 300.

[0087] A shearing member 212 is mounted in the magazine body in a manner that allows it to slide back and forth. The shearing member 212 is fixedly connected to the proximal end of a shearing rod 228, and the distal end of the shearing rod 228 is connected to the blade 223. Driven by the shearing member 212, the shearing rod 228 pulls the blade 223 backward to complete the shearing action;

[0088] A pushing member 213 is mounted in the magazine body in a manner that allows it to slide back and forth. The pushing member 213 is fixedly connected to the proximal end of a pushing rod 227. The pushing rod 227 pushes the proximal anchor 400 forward under the drive of the pushing member 213. The shearing member 212 and the pushing member 213 are arranged in front of each other and are connected by a tension spring 233 so that the two are pulled toward each other;

[0089] A support member 214 is installed between the shearing member 212 and the pushing member 213. The front and rear ends of the support member 214 can move and have two position states: when the support member 214 is in the first position, its front end limits the backward movement of the shearing member 212, and its rear end does not limit the pushing member 213; when the support member 214 is in the second position, its rear end limits the forward movement of the pushing member 213, and its front end does not limit the shearing member 212.

[0090] like Figure 7 As shown, it also includes a support tube 226, which has a semicircular cross-section for mating with the endoscope tube 116. Its upper and lower sides are respectively used to fix the puncture needle tube 224 and the push-pull tube 225. The head end component 222 is provided with an arc-shaped channel connected to the distal end of the puncture needle tube 224, so that the puncture needle 221 can be bent and extended from one side thereof for puncture.

[0091] This embodiment preferably further includes a stroke adjustment mechanism installed in the magazine body for preventing the puncture needle connector 208 from moving forward to control the puncture length.

[0092] This embodiment is preferred, as Figure 9 and Figure 16 As shown, the stroke adjustment mechanism includes a stroke adjustment member 209, which is located in a slide groove of the magazine body and can slide back and forth. The stroke adjustment member 209 is connected to the stroke adjustment cap 204 on the outside of the magazine body via a threaded rod 205. The threaded rod 205 is threadedly connected to the magazine body. The stroke adjustment member 209 is sleeved on the rear end of the threaded rod 205. The stroke adjustment cap 204 is installed at the front end of the threaded rod 205 and can rotate the threaded rod 205. When the stroke adjustment cap 204 rotates, it drives the threaded rod 205 to rotate, thereby controlling the stroke adjustment member 209 to move back and forth along the threaded rod 205. In this way, the blocking position of the stroke adjustment member on the puncture needle connector can be adjusted by rotating the threaded rod, thereby achieving puncture length adjustment. The structure is simple and the adjustment is convenient.

[0093] Further preferably, the stroke adjustment mechanism further includes a buffer pin 206 and an in-place indication cap 203. The threaded rod 205 is a hollow rod with a central hole. The threaded rod 205 is loosely sleeved on the buffer pin 206. The front end of the buffer pin 206 extends beyond the threaded rod 205 and the stroke adjustment cap 204, and is fixedly connected to the in-place indication cap 203. The rear end of the buffer pin 206 extends beyond the threaded rod 205 and is imparted with a buffering tendency by a spring. The buffer pin 206 can slide back and forth within the stroke adjustment member 209 and can abut against the limiting boss 2083 on the puncture needle connector 208. In this way, when the puncture needle connector moves forward, it strikes the buffer pin and fully pushes the buffer pin into the stroke adjustment member, stopping its sliding. Simultaneously, the buffer pin pushes out the in-place indication cap. The buffer pin not only provides a buffering limit for the puncture needle connector, but also facilitates the doctor's quick determination of whether the puncture was successful.

[0094] More preferably, the stroke adjustment mechanism further includes a stroke scale rod 207. The front end of the stroke scale rod 207 is axially fixed to the front end of the threaded rod 205 and can rotate relative to it. The rear end of the stroke scale rod 207 passes through a through hole provided at the front end of the magazine body and is connected to the stroke adjustment member 209 within the magazine body. The stroke scale rod 207 is provided with scale markings corresponding to various puncture lengths. In this way, when the threaded rod moves forward and backward, the stroke scale screw rod moves accordingly to display the scale, which is simple and intuitive, and convenient for quick and easy adjustment of the puncture length.

[0095] In this embodiment, the travel scale rod 207 is made of a bent metal rod, and its front end is bent into an annular ring and arranged on the front part of the threaded rod 205. The flange on the threaded rod 205 cooperates with the travel adjustment cap 204 to clamp the front end annular ring of the travel scale rod 207.

[0096] This embodiment is preferred, as Figure 4 and Figure 5 As shown, the suture holder 211 is mounted within the lumen of the puncture needle connector 208. A guide rod 210 passes through the lumen of the puncture needle connector 208 and is capable of sliding forward and backward with the suture holder 211. A spring 232 is sleeved on the guide rod 210 to impart a backward movement tendency to the suture holder 211. The suture holder 211 is sleeved on the guide rod 210. One end of the spring 232 abuts against the suture holder 211 and the guide rod 210, while the other end of the spring 232 abuts against the puncture needle connector 208. A hook 2091 is provided on the travel adjuster 209. The hook 2091 engages with a groove 2101 provided on the guide rod 210, thereby limiting the backward movement of the guide rod 210. In this way, after the puncture needle is released and the puncture is completed, the hook limits the guide rod and the suture fixing seat to move backward together with the puncture needle connector, which can ensure that the distal anchor can be released from the distal end of the puncture needle; by setting a spring, the suture can be effectively tensioned, making it easier to release the proximal anchor.

[0097] In this embodiment, the proximal end of the suture 500 is connected to a suture support tube 231 to facilitate the push-pull movement of the suture and the connection with the suture fixing seat. The suture support tube is fixed to the suture fixing seat and is crimped and fixed to the suture.

[0098] The shearing component 212, the pushing component 213, the supporting component 214 and their connecting structure form a pushing and shearing mechanism for driving the pushing rod 227 to push the proximal anchor 400 to clamp and fix the suture and for driving the shearing rod 228 to drive the blade 223 to cut the suture.

[0099] This embodiment is preferred, as Figure 9 and Figure 19 As shown, the middle portion of the support member 214 is hingedly connected to the magazine body via a hinge pin 230. A limiting post 2144 is provided below the front end 2141 of the support member 214. This not only prevents the support member 214 from excessively rotating, but also allows for a compression spring to be provided between the support member 214 and the magazine body to force the support member 214 back to its first position. The rear end of the support member 214 includes a first limiting end 2142 and a second limiting end 2143. The two limiting ends are V-shaped, with the first limiting end 2142 always blocking the front of the pushing member 213. This allows the pushing member 213 to promptly push the support member 214 to rotate and limit its position when it moves forward.

[0100] In this embodiment, the support member 214 has an engaged position in which it engages with the shearing member 212, such that the support member 214 can prevent the shearing member 212 from sliding toward the pushing member 213, and a disengaged position in which it disengages from the shearing member 212, such that the support member 214 allows the shearing member 212 to slide toward the pushing member 213. The pushing member 213 is configured to slide into contact with the support member 214 and cause the support member 214 to pivot and disengage from the shearing member 212.

[0101] More preferably, the pushing component 213 and the shearing component 212 slide along the same straight line, and the tension spring 233 is always in a stretched state. The tension released by the tension spring 233 pulls the shearing component 212 and the pushing component 213 toward each other.

[0102] The push shearing mechanism further includes a push locking member 215 disposed within the magazine body. When the push locking member 215 is in an initial position, it is connected to the push component 213 so that the push component 213 is locked and cannot be moved.

[0103] The push locking member can be a locking pin, a locking key or other parts or structures with a locking function.

[0104] This embodiment is preferred, as Figure 18As shown, the push lock member 215 has a hook portion 2151 that engages with the latch portion on the push member 213 to achieve positional locking. The push lock member 215 also has a release portion 2152. The shear trigger lever 113 on the handle pushes the release portion 2152 to move the push lock member 215 left and right, thereby unlocking the push member 213 and implementing suture fixation and cutting.

[0105] In this embodiment, three manual push knobs are slidably provided on the outside of the magazine housing. The first manual push knob 216 extends into the magazine housing and is fixedly connected to the puncture needle connector 208. The second manual push knob 217 extends into the magazine housing and is fixedly connected to the shearing member 212. The third manual push knob 218 extends into the magazine housing and is fixedly connected to the pushing member 213. In this way, when the internal structure of the magazine is stuck, the movement of the puncture needle connector, pushing member, and shearing member inside the magazine can be controlled by moving the manual push knobs on the outside of the magazine housing.

[0106] In this preferred embodiment, the magazine housing 201 is fixed with a cover plate 202, and the two are fixedly connected by a snap-fit structure. The cover plate 202 has three slide slots, and three manual push buttons move forward and backward along the three slide slots. The three manual push buttons are respectively fixedly connected to the puncture needle connector, the shearing component, or the pushing component 213 by the snap-fit structure.

[0107] like Figure 2 The handle 100 shown includes:

[0108] An energy storage slider 106 is disposed within the handle housing in a manner capable of sliding forward and backward and is connected to and moved synchronously with the puncture needle connector 208 in the magazine. The energy storage slider 106 is connected to the handle housing via an energy storage spring 119, thereby imparting a tendency for forward movement. The energy storage slider 106 is connected to the handle housing via a ratchet mechanism, thereby restricting forward movement. When the energy storage slider 106 moves backward into position, the ratchet mechanism is disabled, thereby allowing the energy storage slider 106 to move forward rapidly under the action of the energy storage spring;

[0109] A trigger component 103 is disposed in the handle housing in a manner capable of sliding back and forth. The trigger component 103 is given a tendency to move forward by a trigger spring 125. A sliding push block 104 capable of sliding up and down is disposed on the trigger component 103. The sliding push block 104 can be connected to or disconnected from the energy storage slider 106. When the sliding push block 104 is connected to the energy storage slider 106, the trigger component 103 can drive the energy storage slider 106 to move backward. When the trigger component 103 moves backward into position, the sliding push block 104 is disconnected from the energy storage slider 106, and the trigger component 103 cannot drive the energy storage slider 106 to move.

[0110] A locking member 111 is arranged in the handle housing in a manner that can slide up and down. The locking member 111 has a locked position and an unlocked position: when the locking member 111 is in the locked position, the locking member 111 can limit the trigger component 103 from moving backward, and the pawl mechanism of the energy storage slider 106 is effective, thereby limiting its forward movement; when the locking member 111 is in the unlocked position, the trigger component 103 can move backward, thereby causing the pawl mechanism of the energy storage slider 106 to fail, and the sliding push block 104 to disengage from the energy storage slider 106.

[0111] In this way, by arranging the locking part to cooperate with the trigger part to implement puncture, the risk of misoperation of the trigger single part is avoided, the operation is convenient, and the reliability is good.

[0112] In this preferred embodiment, the handle housing comprises a lower housing 101 and an upper housing 102 fixedly connected together. The upper housing 102 is provided with a magazine compartment for accommodating a magazine. Both the upper housing 102 and the magazine compartment are provided with a slot for a connecting post 2082 on the puncture needle connector 208 to pass through. The connecting post 2082 engages with a slot on the energy storage slide 106 to achieve synchronous movement of the puncture needle connector 208 and the energy storage slide 106.

[0113] An endoscope connecting piece 122 and an endoscope locking piece 123 are respectively provided at the front and rear ends of the handle housing for connecting an endoscope.

[0114] In this embodiment, the magazine cover 202 is preferably provided with a locking button seat 219 and a locking button 220. The locking button seat 219 is fixedly connected to the cover 202 or integrally formed therewith. The locking button 220 is slidably mounted on the cover 202. The locking button seat 219 and the locking button 220 are abutted against each other by a compression spring 229, thereby imparting a tendency for the locking button 220 to be ejected. When the locking button is ejected, it can be fixedly connected to the magazine compartment on the handle via a snap structure. In this way, when an external force is applied to the locking button, the snap structure of the locking button retracts, allowing the magazine to be loaded into the magazine compartment of the handle. When the external force applied to the locking button is removed, the locking button is locked into the handle under the action of the compression spring, at which point the magazine is loaded and the puncture needle connector is fixedly engaged with the energy storage slider.

[0115] In this embodiment, the sliding push block 104 is preferably connected to the trigger component 103 via a compression spring 117. In a natural state, the sliding push block 104 is in an ejected state under the thrust of the compression spring, so that it can be connected to the energy storage slider 106. In other embodiments, the sliding push block can also be connected to the trigger component via a tension spring or the like.

[0116] In this embodiment, a guide shaft 105 is fixed to the lower housing 101, the energy storage slider 106 is sleeved on the guide shaft 105 and can slide back and forth along the guide shaft 105, and the energy storage spring 119 is a compression spring sleeved on the guide shaft 105. In other embodiments, the energy storage spring can also be a tension spring.

[0117] In this embodiment, the trigger member 103 preferably slides forward and backward by means of slides provided on its left and right sides, cooperating with the slide grooves on the lower housing 101 and the upper housing 102. The trigger spring 125 is a tension spring that passes through a through hole in the trigger member 103. The ends of the tension spring are connected to the trigger member and the handle housing, respectively, via connecting pins. In other embodiments, the trigger spring may also be a compression spring.

[0118] In this embodiment, the pawl mechanism preferably includes a retaining block 107, a locking slider 108, and a connecting rod 109. The retaining block 107 and the locking slider 108 are each slidably mounted on the energy storage slider 106. One end of the retaining block 107 is hinged to one end of the connecting rod 109, and the other end of the connecting rod 109 is hinged to one end of the locking slider 108. The other end of the locking slider 108 can be pushed out or retracted. When the locking slider 108 is pushed out, it can cooperate with the ratchet on the first limiter 1011 to limit the forward movement of the energy storage slider 106. When the locking slider 108 is retracted, the pawl mechanism is disabled. The retaining block 107 is connected to the energy storage slider 106 via a retaining spring 118, so that the retaining block 107 imparts a tendency for the locking slider 108 to maintain the tendency to be pushed out or retracted. In this way, the structure is simple and reasonable, the unidirectional stepping motion of the energy storage slider is highly reliable, and release and release are convenient.

[0119] More preferably, the retaining block 107 is mounted on the energy storage slider 106 in a manner that allows it to slide back and forth, and the locking slider 108 is mounted on the energy storage slider 106 in a manner that allows it to slide up and down, with the lower end of the locking slider 108 being able to be pushed out or retracted. In other embodiments, the locking slider can also be pushed out from above or from the left or right sides of the energy storage slider and cooperate with corresponding ratchets on the handle housing to achieve unidirectional stepping motion.

[0120] In this embodiment, in the initial state, the holding block 107 pushes the connecting rod 109 to pivot, pushing the locking slider 108 to move downward, so that the locking slider 108 is located at and maintained in the ejected position.

[0121] Further preferably, the retaining spring 118 is a compression spring, which is arranged in a slide groove on the handle housing for arranging the retaining block 107. In other embodiments, the retaining spring can also be a tension spring.

[0122] In this embodiment, the locking slider 108 and the connecting rod 109 are preferably hingedly connected by a hinge pin 110. One end of this hinge pin 110 extends into a slot 1022 in the handle housing. This slot 1022 is provided on either the upper or lower handle housing. The rear end of the slot 1022 is formed into a rising ramp. When the hinge pin 110 moves rearward to this point, it is lifted, and the locking slider 108 remains retracted. The front portion of the slot 1022 is provided with a descending ramp 2092 formed on the stroke adjustment member 209. When the hinge pin 110 moves forward to this point, it is depressed, and the locking slider 108 remains extended. In this embodiment, the slot 1022 is provided in the magazine compartment wall of the upper housing 102. Another slot 1021 is also provided in the magazine compartment wall of the upper housing 102 to allow the connecting post 2082 on the puncture needle connector 208 in the magazine to extend into the handle housing and connect with the energy storage slider.

[0123] In this embodiment, when the trigger member 103 moves backward, the sliding block 104 abuts against the sloped boss on the first stopper 1011 and moves downward, thereby disengaging from the energy storage slider 106. The first stopper 1011 is fixedly connected to the lower housing 101 or is integrally formed.

[0124] In this embodiment, the locking member 111 is preferably connected to the lower shell 101 by a spring 124 so as to be given a tendency to move upward, and a locking boss 1111 is provided on the locking member 111 for limiting the backward movement of the trigger member 103, and the locking boss 1111 is protruding forward; an unlocking pin 112 that can slide back and forth is installed on the locking member 111, and the unlocking pin 112 is pushed forward by the compression spring 121 against the locking member 111; when the unlocking pin 112 is pushed forward and inserted into the limiting groove on the second limiting member 1012, the locking member 111 is in the locked position, and the locking boss 111 is in the locked position. 111 can abut against the protrusion at the rear end of the trigger member 103, thereby limiting the rearward movement of the trigger member 103. When the unlocking pin 112 is pushed forward and abuts against the limiting protrusion on the second limiting member 1012, the locking member 111 is in the unlocked position. The locking protrusion 1111 and the protrusion at the rear end of the trigger member 103 are vertically offset, no longer limiting the rearward movement of the trigger member 103. When the trigger member 103 continues to move backward into position, the protrusion at the rear end of the trigger member 103 pushes the unlocking pin 112 back, and the locking member 111 moves upward under the action of the spring to return to the locked position. The limiting groove and limiting protrusion on the second limiting member 1012 are arranged vertically and are transitioned by a slope. The second limiting member 1012 is fixedly connected to the lower housing 101 or integrally formed. The spring 124 is a tension spring or a compression spring. In this way, the lock is unlocked by pressing the locking member, and the trigger member is used to trigger the puncture and push back the unlocking pin to achieve re-locking, avoiding the risk of misoperation of re-puncture.

[0125] In this embodiment, the locking member 111 is initially in the locked position. A compression spring 121 and a retaining spring 120 are sleeved around the unlocking pin 112. The retaining spring 120 engages within the retaining groove of the unlocking pin 112, with the ends of the compression spring 121 respectively abutting against the locking member 111 and retaining spring 120. Thus, the compression spring applies an outward thrust to the unlocking pin, causing the unlocking pin 112 to engage with the retaining groove of the second retaining member 1012, thereby maintaining the locking member 111 in the locked position.

[0126] In this embodiment, the handle is preferably provided with a shearing trigger rod 113 and an elastic stopper. The shearing trigger rod 113 is mounted within the handle housing in a manner that allows it to slide up and down. The shearing trigger rod 113 is fixedly connected to a shearing push button 115 that is slidably disposed outside the handle housing. The elastic stopper is used to lock the shearing trigger rod 113 to prevent it from moving up and down. When the trigger component 103 moves backward into position, it pushes against the elastic stopper to unlock, thereby allowing the shearing trigger rod 113 to move up and down. The shearing trigger rod 113 pushes the release portion 2152 on the push locking member 215 to move the push locking member 215 left and right, thereby unlocking the push component 213 and allowing the push shearing mechanism to clamp and cut the suture. In this way, the push shearing mechanism can only be activated after the trigger component moves backward into position, ensuring that the distal anchor is released and the suture is tensioned before clamping and cutting the suture, thereby avoiding the risk of surgical misoperation.

[0127] Further preferably, both the handle housing and the magazine housing are provided with a through-hole through which the shear trigger rod 113 passes. The upper portion of the shear trigger rod 113 is U-shaped, with one end extending through the through-hole into the magazine to unlock the push-locking member 215, while the other end cooperates with the locking member 111 to limit position: when the locking member 111 is in the unlocked position, the locking member 111 can restrict the upward movement of the shear trigger rod 113; when the locking member 111 is in the locked position, the shear trigger rod 113 is not restricted. In this way, the push-shear mechanism can only be activated when the locking member is locked, avoiding the surgical risks caused by the push-shear mechanism malfunctioning during puncture.

[0128] Further preferably, the shear trigger rod 113 is installed in a slide groove formed by the upper shell 102 and the lower shell 101 and can slide up and down. It is connected to the shear push button 115 through a snap-fit structure. The elastic stopper is an elastic stop bar 114. The elastic stop bar 114 is V-shaped. One end of the elastic stop bar 114 is fixed in the slot of the lower shell 101, and the other end of the elastic stop bar 114 is inserted into the slot on the shear trigger rod 113. When the shear trigger rod 113 is in the initial position, the elastic stop bar 114 contacts the boss of the lower shell 101, locking the shear trigger rod 113 so that it cannot move. When the trigger component 103 moves back into place, the elastic stop bar 114 is compressed, and the other end of the elastic stop bar 114 withdraws from the slot on the shear trigger rod 113, allowing the shear trigger rod 113 to move up and down.

[0129] The method of using the above-mentioned anchor delivery system is as follows:

[0130] 1) Applying external force to the trigger component 103 for the first time causes the trigger component 103 to move the energy storage slider 106 and the puncture needle connector 208 backward to store energy;

[0131] 2) Press the locking member 111 to unlock;

[0132] 3) Continue to apply external force to the trigger component 103, the energy storage slider 106 drives the puncture needle connector 208 to move forward and fire, the puncture needle 221 and the distal anchor 300 extend out of the head end component 222 at the distal end of the puncture needle tube 224, the locking member 111 returns to its original position, and the external force applied to the trigger component 103 is removed to reset it;

[0133] 4) Applying external force to the trigger component 103 again causes the trigger component 103 to move the energy storage slider 106 and the puncture needle connector 208 backward to retract the puncture needle 221 and tighten the suture;

[0134] 5) Push the shear push button 115 to unlock the pushing component 213, which pulls the pushing component 213 toward the shearing component 212, pushing the proximal anchor out of the head end component 222 at the distal end of the puncture needle tube 224, and the pushing component 213 is limited by the support component 214, unlocking the shearing component 212, which pulls the shearing component 212 toward the pushing component 213, driving the shear rod and the blade to cut the suture.

[0135] The specific action coordination process is described as follows:

[0136] Apply external force to the locking button, and the buckle structure of the locking button retracts, and the magazine can be loaded into the magazine compartment of the handle. Remove the external force applied to the locking button, and the locking button is locked into the handle under the action of the compression spring. At this time, the magazine loading is completed, and the puncture needle connector 208 is fixed to the energy storage slider 106. Figure 6 shown.

[0137] Rotate the stroke adjustment cap 204 to drive the threaded rod 205 to rotate. At this time, the stroke adjustment member 209 can move forward and backward according to the rotation of the threaded rod 205, and drive the stroke scale screw rod to move at the same time. After confirming the position of the stroke scale screw rod, stop rotating the stroke adjustment cap 204. Figure 9 shown.

[0138] like Figure 10 As shown, when an external force is applied to the trigger component 103, it slides backward along the slide groove from the initial state of the first position, driving the sliding push block 104 to contact the energy storage slider 106, and driving the energy storage slider 106 to move backward at the same time until the trigger component 103 contacts the locking member 111. At this time, the trigger component 103 is limited by the locking member 111 and cannot continue to slide backward. Figure 11As shown, the locking slider 108 is engaged with the ratchet structure in the lower shell 101 at the same time. At this time, the energy storage slider 106 is located in the second position, and the compression spring completes the accumulation of mechanical energy. At this time, the external force applied to the trigger component 103 is removed, and under the tension of the tension spring, the trigger component 103 is reset to the first position.

[0139] like Figure 12 As shown, downward pressure is applied to the locking member 111, the locking member 111 slides downward, and the unlocking pin 112 is compressed until it continues to slide downward to the unlocking position. The compression spring drives the unlocking pin 112 to pop out and engage with the limiting protrusion on the second limiting member 1012, fixing the locking member 111, and completing the unlocking of the trigger member 103. Figure 13 As shown. External force is applied to the trigger component 103 again, and the trigger component 103 moves backward from the first position again. When the sliding push block 104 contacts the energy storage slider 106 again, it can drive the energy storage slider 106 to continue to slide backward. The trigger component 103 continues to slide backward until it contacts the unlocking pin 112 and continues to move, compressing the unlocking pin 112 until the sliding push block 104 contacts the trapezoidal boss (sloped boss) on the first limit member. During the backward sliding process, the trapezoidal boss exerts a downward pressure on the sliding push block 104, pressing the sliding push block 104 to the second position. At this time, the sliding push block 104 is released from the energy storage slider 106, as shown. Figure 14 As shown, at the same time, the locking slider 108 is lifted upward and maintained in the second position (retracted state) under the action of the lifting slope of the slide groove 1022 on the handle housing, as shown in FIG. Figure 15 As shown, at this time, the locking slider 108 is unlocked from the ratchet structure on the first limit member, and the energy storage slider 106 loses all locks and slides forward rapidly under the action of the compression spring, and drives the puncture needle connector 208 to slide forward, and the puncture needle connector 208 drives the suture fixing seat 211 and the guide rod 210 to slide forward until the puncture needle connector 208 contacts the buffer pin 206 and drives it to continue to slide forward, and the buffer pin 206 drives the in-place prompt cap 203 to slide forward until the buffer pin 206 contacts the stroke adjustment member 209, as shown in FIG. Figure 22 As shown, the puncture is completed, and the in-place prompt cap 203 is fully popped out, indicating that the puncture is in place, and the energy storage slider 106, the puncture needle connector 208, the suture fixing seat 211 and the guide rod 210 all stop sliding and are in the second position. When the locking slider 108 slides forward to the position, it is pushed downward under the action of the descending slope of the slide groove 1022 on the handle housing, and returns to and remains in the first position, as shown. Figure 16When the external force applied to the trigger member 103 is removed, the trigger member 103 returns to the first position again under the action of the tension spring, and the unlocking pin 112 is compressed in the locking member 111, losing the restraining force on the locking member 111. Under the action of the compression spring, the locking member 111 slides upward, and the unlocking pin 112 pops out again under the action of the compression spring and is fixed in the limiting groove of the lower housing 101. The locking member 111 returns to the first position (locked position) again, thus locking the trigger member 103.

[0140] Apply external force to the trigger component 103 again, the trigger component 103 slides backward, the sliding push block 104 drives the energy storage slider 106 to move backward again, the energy storage slider 106 drives the puncture needle connector 208 to slide backward, and the puncture needle connector 208 drives the suture fixing seat 211 and the guide rod 210 to slide backward. Figure 17 As shown, when the slot of the guide rod 210 moves to the hook of the stroke adjustment member 209 and engages, the guide rod 210 and the suture fixing seat 211 stop moving backward, and the puncture needle connector 208 continues to retreat to complete the release of the distal anchor until the trapezoidal boss 2081 on the puncture needle connector 208 lifts the hook of the stroke adjustment member 209, releasing the guide rod 210 to continue sliding backward and tightening the suture. At this time, the puncture needle is completely retracted and the distal anchor is released. Figure 23 shown.

[0141] like Figure 18 and Figure 19 As shown, in the initial state, the push locking member 215 is connected to the push member 213, so that the push member 213 is locked and cannot move. When the trigger member 103 moves backward, the elastic stop bar 114 is squeezed into the card slot of the lower shell 101 and the shear trigger rod 113 is unlocked at the same time. The trigger member 103 is continuously applied with external force, and an upward thrust is applied to the shear push button 115, which drives the shear trigger rod 113 to move upward from the first position to the second position until the shear trigger rod 113 contacts the push locking member 215 and pushes the push locking member 215 away, causing it to slide sideways until the hook portion of the push locking member 215 is disengaged from the push member 213. Figure 20 As shown, at this time, the tension spring 233 pulls the pushing member 213 toward the shearing member 212, pushing the proximal anchor member forward until the pushing member 213 collides with the support member 214, causing the support member 214 to pivot to unlock the shearing member 212, as shown in FIG. Figure 21As shown, under the action of the tension spring, the shearing component 212 slides toward the pushing component 213, driving the shear rod to complete the shearing. If the structure jams during this process and the action cannot be completed smoothly, manual operation can be performed by manually pushing and twisting. When the thrust on the shear push button 115 is removed, it returns to the first position under the action of the compression spring. When the external force on the trigger component 103 is removed, it returns to the first position again under the action of the tension spring. At this time, the energy storage slider 106 remains in the second position under the action of the locking slider 108, maintaining the energy storage state. The elastic stop bar 114 loses the external force and returns to its original state, continuing to lock the shear trigger rod 113.

[0142] After that, the magazine is replaced, the handle parts have been reset, the energy storage slide 106 is in the energy storage position, and the next round of puncture can be carried out directly after loading a new magazine. Figure 24 shown.

[0143] Example 2:

[0144] like Figure 25 An anchor delivery system shown includes a handle 100 and a magazine 200. The magazine 200 is mounted on the handle 100 in a detachable and replaceable manner. The handle 100 transfers its own stored mechanical energy to the magazine 200 to deliver the implant into the patient's body.

[0145] Wherein handle 100 is as Figure 26 As shown, a handle of an anchor delivery system comprises:

[0146] a handle housing;

[0147] An energy storage slider 106 is arranged in a manner that allows it to slide back and forth within the handle housing and can be connected to and move synchronously with the puncture needle connector 208 in the magazine. The energy storage slider 106 is connected to the handle housing via an energy storage spring 119, thereby giving it a tendency to move forward. A locking slider 108 that can be pushed out or retracted is slidably provided on the energy storage slider 106: when the locking slider 108 is pushed out, it cooperates with the first limiting member 1011 on the handle housing to limit the forward movement of the energy storage slider 106; when the energy storage slider 106 moves backward into place, the locking slider 108 retracts and disengages from the ratchet on the handle housing;

[0148] A trigger component 103 is arranged in the handle housing in a manner that allows it to slide back and forth. The trigger component 103 is given a tendency to move forward by a trigger spring 125. A sliding push block 104 is slidably arranged on the trigger component 103. The sliding push block 104 can be connected to or disconnected from the energy storage slide 106: when the sliding push block 104 is connected to the energy storage slide 106, the trigger component 103 can drive the energy storage slide 106 to move backward; when the trigger component 103 moves backward into place, the sliding push block 104 is disconnected from the energy storage slide 106;

[0149] A first knob 126 is mounted in the handle housing in a deflectable manner. Figure 28 As shown, the initial state of the locking slider 108 is the ejected state. When the energy storage slider 106 moves backward into position, the energy storage slider 106 applies force to one leg 1261 of the first knob 126, causing the first knob 126 to deflect. The other leg 1262 of the first knob 126 to toggle the locking slider 108, causing the locking slider 108 to retract and disengage from the first limiting member 1011 on the handle housing, thereby unlocking the energy storage slider 106 and the handle housing.

[0150] A second knob 127 is mounted in the handle housing in a deflectable manner. Figure 27 As shown, the initial state of the sliding push block 104 is the ejected state. When the trigger component 103 moves backward into position, the trigger component 103 applies force to one leg 1271 of the second knob 127, causing the second knob 127 to deflect, and the other leg 1272 of the second knob 127 moves the sliding push block 104, causing the sliding push block 104 to disengage from the energy storage slider 106; thereby unlocking the energy storage slider 106 and the trigger component 103.

[0151] As can be seen from Example 1, the trigger assembly 103 drives the energy storage slider 106 to move and store energy via the sliding push block 104. After the energy storage slider 106 is stored, it is locked to its position with the handle housing via the locking slide 108. To unlock the energy storage slider 106 for firing and puncture, both the unlocking sliding push block 104 and the locking slide 108 must be moved promptly. In Example 1, the locking slide 108 retracts via a ramp, resulting in excessive friction and a long ramp distance. This causes the energy storage slider to move a long distance backward, resulting in a large amount of spring compression, which in turn increases the force transmitted to the trigger and increases operator effort. In Example 1, the sliding push block 104 on the trigger assembly can be connected to or disconnected from the energy storage slider 106. This disconnection is achieved by downward movement of the sliding push block via a ramped boss, which results in relatively high friction.

[0152] This embodiment provides a new method for unlocking the lock by rotating the knob. The energy storage slider applies force to the first knob from one side, forcing it to deflect. The other leg of the first knob pushes the locking slider pin upward, causing the locking slider to retract upward. Similarly, the trigger applies force to the second knob from one side, causing it to deflect. The other leg of the second knob pushes the sliding block downward, causing it to retract. The sliding block can then disengage from the energy storage slider, effectively unlocking the energy storage slider. In this way, the knob deflection retracts the locking slider, causing the sliding block to move downward, thereby unlocking the energy storage slider. This reduces friction, shortens the movement distance of the energy storage slider, and makes operation easier.

[0153] In this embodiment, the first knob 126 and the second knob 127 are preferably arranged in the handle housing in a manner that they can rotate along the central axis.

[0154] Preferably, in this embodiment, a first torsion spring 128 is sleeved on the rotating shaft of the first knob 126, one end of the first torsion spring 128 is connected to the handle housing, and the other end of the first torsion spring 128 is connected to the first knob 126, thereby giving the first knob 126 a tendency to return to its original position after deflection; a second torsion spring 129 is sleeved on the rotating shaft of the second knob 127, one end of the second torsion spring 129 is connected to the handle housing, and the other end of the second torsion spring 129 is connected to the second knob 127, thereby giving the second knob 127 a tendency to return to its original position after deflection.

[0155] In this embodiment, the first knob 126 drives the locking slider 108 to retract by turning the hinge pin 110 on the locking slider 108. The second knob 127 drives the sliding push block 104 to retract by turning the protrusion 1041 provided on the sliding push block 104.

[0156] In this embodiment, preferably, the first knob 126 has a leg 1261 in contact with the energy storage slider 106 that is shorter than the other leg 1262 in contact with the locking slider 108, and the second knob 127 has a leg 1271 in contact with the trigger member 103 that is shorter than the other leg 1272 in contact with the sliding push block 104. This allows for faster unlocking and more convenient and easy operation.

[0157] In this preferred embodiment, the first stopper 1011 on the handle housing differs from that in Example 1 in that it is provided with only a single ratchet that engages the locking slider 108 on the energy storage slider 106. The first stopper 1011 is fixedly connected to or integrally formed with the lower housing 101. Because the sliding block is retracted by turning the second knob, the first stopper no longer has a trapezoidal or sloped projection to press the sliding block downward. Because the locking slider is retracted by turning the first knob, the handle housing no longer has a slope to push the slide hinge pin 110.

[0158] In this embodiment, the installation structure of the sliding push block and the installation structure of the locking slider are the same as those in the first embodiment.

[0159] Similar to Example 1, in this embodiment, the handle further includes a locking member 111, which is disposed within the handle housing in a manner capable of sliding up and down. The locking member 111 has a locked position and an unlocked position: when the locking member 111 is in the locked position, the locking member 111 can restrict the trigger member 103 from moving backward, and the energy storage slide 106 is restricted from moving forward; when the locking member 111 is in the unlocked position, the trigger member 103 can move backward, thereby causing the pawl mechanism of the energy storage slide 106 to fail and the sliding push block 104 to disengage from the energy storage slide 106. In this way, by providing a locking member and a trigger member to cooperate in puncture, the risk of malfunction caused by a single trigger member firing is avoided, and the operation is convenient and the reliability is good.

[0160] This embodiment is also preferred. The locking member 111 is connected to the lower housing 101 by a spring 124 so as to be given a tendency to move upward. The locking member 111 is provided with a locking boss 1111 for limiting the rearward movement of the trigger member 103. The locking boss 1111 is provided to protrude forward. An unlocking pin 112 capable of sliding forward and backward is installed on the locking member 111. The unlocking pin 112 is pushed forward by the compression spring 121 against the locking member 111. Figure 29 As shown, when the locking member is in the initial state, the unlocking pin 112 is pushed forward and inserted into the limiting groove on the second limiting member 1012, and the locking member 111 is in the locked position, as shown in FIG. Figure 32 As shown, the locking boss 1111 can abut against the protrusion at the rear end of the trigger member 103 to limit the trigger member 103 from moving backward; Figure 29 As shown, the locking member moves downward after being pressed, and the unlocking pin 112 moves out of the limiting groove and pushes forward and abuts against the limiting protrusion on the second limiting member 1012. The locking member 111 is in the unlocked position, and the locking boss 1111 and the protrusion at the rear end of the trigger member 103 are misaligned up and down, thereby no longer restricting the trigger member 103 from moving backward; Figure 35 As shown, when the trigger member 103 continues to move backward into position, the protrusion at the rear end of the trigger member 103 pushes the unlocking pin 112 back, and the locking member 111 moves upward under the action of the spring to return to the locked position. The limiting groove and limiting protrusion on the second limiting member 1012 are arranged vertically, with a sloped transition between them. The second limiting member 1012 is fixedly connected to or integrally formed with the lower housing 101. In this way, the locking member can be unlocked by pressing the locking member, and the trigger member can be fired to puncture and simultaneously push the unlocking pin back to achieve re-locking, thus avoiding the risk of accidental re-puncture.

[0161] In this embodiment, the installation structure of the spring 124 and the unlocking pin 112 is the same as that of the first embodiment.

[0162] In this embodiment, the handle is preferably provided with a shearing trigger rod 113 and an elastic stopper. The shearing trigger rod 113 is mounted in the handle housing in a manner that allows it to slide up and down. The shearing trigger rod 113 is integrally formed with a shearing push button provided on the outside of the handle housing. The elastic stopper is used to lock the shearing trigger rod 113 to prevent it from moving up and down. When the trigger component 103 moves backward into position, it pushes against the elastic stopper to unlock, thereby allowing the shearing trigger rod 113 to move up and down. The shearing trigger rod 113 pushes the release portion 2152 on the push locking member 215 to rotate the push locking member 215, thereby unlocking the push component 213 and allowing the push shearing mechanism to clamp and cut the suture. In this way, the push shearing mechanism can only be activated after the trigger component moves backward into position, ensuring that the distal anchor is released and the suture is tensioned before the suture is clamped and cut, thereby avoiding the risk of surgical misoperation.

[0163] In this embodiment, both the handle housing and the magazine housing are preferably provided with through-holes through which the shear trigger rod 113 passes. The upper portion of the shear trigger rod 113 is U-shaped, with one end extending through the through-hole into the magazine to unlock the push-locking member 215. The other end of the upper portion cooperates with the locking member 111 to limit position: when the locking member 111 is in the unlocked position, the locking member 111 can restrict the upward movement of the shear trigger rod 113; when the locking member 111 is in the locked position, the shear trigger rod 113 is not restricted. In this way, the push-shear mechanism can only be activated when the locking member is locked, avoiding the surgical risks caused by the push-shear mechanism malfunctioning during puncture.

[0164] In this embodiment, the shear trigger rod 113 is preferably installed in the slide groove formed by the upper shell 102 and the lower shell 101 and can slide up and down. In this embodiment, the elastic limit member includes a limit bolt 131 and a limit bolt spring 132. The limit bolt 131 is connected to the handle housing through the limit bolt spring 132 and can move and elastically reset. The limit bolt 131 crosses the shear trigger rod 113. Figure 30 As shown, in the initial state, the limit pin 131, under the action of the limit pin spring 132, has its large head positioned inside the shear trigger rod 113, limiting the shear trigger rod 113 and preventing it from moving up and down. When the limit pin 131 is displaced backward by the force of the trigger member 103, the large head of the limit pin 131 leaves the shear trigger rod 113, and the shear trigger rod 113 is unlocked and can move upward under the action of the thumb. When the thumb releases the force, the shear trigger rod 113 returns to its initial position under the action of the trigger rod spring 130. When the trigger member 103 moves forward and leaves the limit pin 131, the limit pin 131 returns to its initial position under the action of the limit pin spring 132, and the shear trigger rod 113 is locked again by the limit pin 131.

[0165] The other structures of the handle are the same as those in Example 1.

[0166] like Figure 37 The magazine 200 shown includes:

[0167] A puncture needle tube 224, in which a puncture needle 221 capable of moving back and forth is inserted, the proximal end of the puncture needle tube 224 is fixedly connected to the front end of the magazine body, and the distal end of the puncture needle tube 224 is fixedly connected to the head end component 222;

[0168] A push-pull tube 225, through which a shear rod 228 and a push rod 227 capable of moving back and forth are inserted, the proximal end of the push-pull tube 225 is fixedly connected to the front end of the magazine body, and a proximal anchor 400 capable of moving back and forth and being disengaged is provided in the distal opening of the push-pull tube 225, and the distal end of the push-pull tube 225 is fixedly connected to the head end component 222;

[0169] A puncture needle connector 208, the front portion of which is fixedly connected to the proximal end of a puncture needle 221. A suture 500 capable of moving back and forth is passed through the puncture needle 221. The proximal end of the suture 500 is fixedly connected to a suture holder 211. The suture holder 211 is mounted on the puncture needle connector 208 in a manner that allows it to slide back and forth. The distal end of the suture 500 is fixedly connected to the distal anchor 300.

[0170] A shearing member 212 is mounted in the magazine body in a manner that allows it to slide back and forth. The shearing member 212 is fixedly connected to the proximal end of a shearing rod 228, and the distal end of the shearing rod 228 is connected to the blade 223. Driven by the shearing member 212, the shearing rod 228 pulls the blade 223 backward to complete the shearing action;

[0171] A pushing member 213 is mounted in the magazine body in a manner that allows it to slide back and forth. The pushing member 213 is fixedly connected to the proximal end of a pushing rod 227. The pushing rod 227 pushes the proximal anchor 400 forward under the drive of the pushing member 213. The shearing member 212 and the pushing member 213 are arranged in front of each other and are connected by a tension spring 233 so that the two are pulled toward each other;

[0172] A support member 214 is installed between the shearing member 212 and the pushing member 213. The front and rear ends of the support member 214 can move and have two position states: when the support member 214 is in the first position, its front end limits the backward movement of the shearing member 212, and its rear end does not limit the pushing member 213; when the support member 214 is in the second position, its rear end limits the forward movement of the pushing member 213, and its front end does not limit the shearing member 212.

[0173] Among them, the tension spring 233 is always in a stretched state, and the tension released by it pulls the shearing component 212 and the pushing component 213 towards each other; the head end component 222, the puncture needle tube 224, the support tube 226, and the push-pull tube 225 are connected together through a welding process, wherein the shear rod 228 can slide in the inner cavity of the push-pull tube 225.

[0174] In this embodiment, a support tube 226 is also included. The support tube has a cross-section of ] for mating with the endoscope tube 116. Its upper and lower sides are respectively used to securely connect the puncture needle tube 224 and the push-pull tube 225. The head end component 222 has an arc-shaped channel connected to the distal end of the puncture needle tube 224, so that the puncture needle 221 can be bent and extended from one side thereof for puncture.

[0175] This embodiment is preferred, as Figure 37 and Figure 38 As shown, a guide rod 210 passes through the puncture needle connector 208, and the suture holder 211 is mounted on the guide rod 210 and can slide back and forth on the puncture needle connector 208. The guide rod 210 is also mounted with a spring 232 for imparting a backward movement tendency to the suture holder 211. One end of the spring 232 abuts against the suture holder 211, and the other end of the spring 232 abuts against the puncture needle connector 208.

[0176] This embodiment is preferred, as Figure 38 As shown, the puncture needle connector 208 is provided with a guide groove 2084, the top of the puncture needle connector 208 is provided with a groove 2086 running through the front and back and a slope structure 2085 that descends and tilts backward, and the side of the suture fixing seat 211 is provided with a guide platform portion 2111, which slides with the guide groove 2084 on the puncture needle connector 208, and the top of the suture fixing seat 211 is provided with a slope surface 2112 and a card slot 2113.

[0177] This embodiment is preferred, as Figure 37 、 Figures 39 to 43As shown, a suture reset pin 235 is provided in the magazine. The lower end of the suture reset pin 235 is provided with a flange and a downwardly protruding portion. The flange slides with the ramp 2085 on the puncture needle connector 208, and the downwardly protruding portion is limited by the slot 2113 on the suture fixing seat 211. The upper portion of the suture reset pin 235 is square and cylindrical. The suture reset pin 235 can slide up and down within the slide slot in the magazine, and cannot rotate due to the square structure. A pin reset spring 237 is sleeved on the suture reset pin 235. One end of the pin reset spring 237 abuts against the magazine, and the other end of the pin reset spring 237 is abutted by a retaining ring 236 fixed to the suture reset pin 235. Therefore, the pin reset spring 237 can exert downward pressure on the suture reset pin 235, and the retaining ring 236 can abut against the magazine to limit the downward movement range of the suture reset pin 235.

[0178] like Figure 40 and Figure 41 As shown, when the puncture needle connector 208 moves forward to the bottom in the magazine, the suture reset pin 235 moves downward under the action of the pin reset spring 237 and cooperates with the slot 2113 on the suture fixing seat 211 to keep it stationary. When the puncture needle connector 208 moves backward, the suture fixing seat 211 remains stationary under the action of the suture reset pin 235, that is, the release of the distal anchor 300 is completed. At the same time, the suture reset pin 235 moves on the inclined structure 2085 of the puncture needle connector 208 and is gradually raised until the suture fixing seat 211 is unlocked. The suture fixing seat 211 slides backward under the action of the suture reset spring 232 to complete the tightening of the suture. In this way, after the puncture needle is released and the puncture is completed, the suture fixing seat is restricted by the suture reset pin to move backward together with the puncture needle connector, thereby ensuring that the distal anchor can be released from the distal end of the puncture needle; by setting a spring, the suture can be effectively tensioned, facilitating the release of the proximal anchor.

[0179] The shearing member 212, the pushing member 213, the support member 214, and their connection structure form a push-shear mechanism, which is used to drive the pushing rod 227 to push the proximal anchor 400 to clamp and secure the suture, and to drive the shearing rod 228 to drive the blade 223 to cut the suture. The push-shear mechanism also includes a push locking member 215 disposed within the magazine body. When the push locking member 215 is in the initial position, it is connected to the pushing member 213, so that the pushing member 213 is locked and cannot move.

[0180] This embodiment is preferred, as Figure 44 and Figure 45As shown, the push locking member 215 is installed in the magazine body, and one end of the push locking member 215 is a hook portion 2151, which cooperates with the push component 213 to realize limit locking, and the other end of the push locking member 215 is a release portion 2152. The shear trigger rod 113 on the handle pushes the release portion 2152 to realize the swinging of the push locking member 215, thereby releasing the lock of the push component 213, and implementing suture fixation and cutting.

[0181] In this embodiment, a cover plate 202 is fixed to the magazine body 201, and the two are fixedly connected by fasteners. The magazine also includes a locking push button 220 that moves from an unlocked position to a locked position. Figure 36 As shown, after the magazine is placed in the magazine compartment on the handle, the extended end of the locking push button 220 is inserted into the socket 1023 on the magazine compartment of the handle, so that the magazine is fixed to the handle. A safety cover 238 is housed on the cover plate 202 to avoid the magazine from being misactivated during non-operative time.

[0182] This embodiment is preferred, as Figure 46 As shown, the magazine cover 202 is provided with a locking button seat 219 and two upper and lower locking buttons 220. The locking button seat 219 is fixedly connected to the cover 202 or formed integrally therewith. The locking buttons 220 are slidably mounted on the cover 202. The locking button seat 219 and the locking buttons 220 are resisted by a compression spring 229, thereby imparting a tendency for the locking buttons 220 to be ejected. When the locking buttons are ejected, their protruding ends can be fixedly connected to the magazine compartment on the handle via a snap structure. In this way, when an external force is applied to the locking buttons, the snap structure of the locking buttons retracts, allowing the magazine to be loaded into the magazine compartment of the handle. When the external force applied to the locking buttons is removed, the locking buttons are locked into the handle under the action of the compression spring, completing the magazine loading. The puncture needle connector is fixed to the energy storage slider.

[0183] This embodiment is further preferred, the locking button seat 219 is fixed to the magazine by a snap-fit structure, the locking button 220 can slide up and down in the slide groove in the magazine, a spring pin 234 is fixed on the locking button seat 219, and two upper and lower compression springs 229 are mounted on the spring pin 234 and generate thrust on the upper and lower locking buttons 220 respectively.

[0184] The other structures of the magazine of this embodiment are the same as those of embodiment 1.

[0185] This embodiment also discloses an anchor delivery system using the handle and magazine. The method of using the anchor delivery system is the same as that of embodiment 1. The specific action coordination process is described as follows:

[0186] When loading a magazine, an external force is applied to the locking button, and the buckle structure of the locking button is retracted. The magazine can be loaded into the magazine compartment of the handle. The external force applied to the locking button is removed, and the locking button is locked into the handle under the action of the compression spring. At this time, the magazine loading is completed, and the puncture needle connector 208 is fixedly connected to the energy storage slider 106. Figure 36 shown.

[0187] The initial state of the handle is as follows Figure 31 As shown, when an external force is applied to the trigger component 103, it slides backward along the slide groove from the initial state of the first position, driving the sliding push block 104 to contact the energy storage slider 106, and driving the energy storage slider 106 to move backward at the same time until the trigger component 103 contacts the locking member 111. At this time, the trigger component 103 is limited by the locking member 111 and cannot continue to slide backward. Figure 32 As shown, the locking slider 108 is engaged with the ratchet structure in the lower housing 101. At this time, the energy storage slider 106 is located in the second position, and the compression spring completes the accumulation of mechanical energy. At this time, the external force applied to the trigger component 103 is removed. Under the tension of the tension spring, the trigger component 103 returns to the first position, as shown in FIG. Figure 33 shown.

[0188] like Figure 34 As shown, downward pressure is applied to the locking member 111, the locking member 111 slides downward, and the unlocking pin 112 is compressed back until it continues to slide downward to the unlocking position. The compression spring drives the unlocking pin 112 to pop out and engage with the limiting protrusion on the second limiting member 1012, fixing the locking member 111 and completing the unlocking of the trigger member 103. Figure 35As shown, external force is applied to the trigger component 103 again, and the trigger component 103 moves backward from the first position again. When the sliding push block 104 contacts the energy storage slider 106 again, the energy storage slider 106 can be driven to slide backward, and the trigger component 103 continues to slide backward and hits the unlocking pin 112 until it rests against the locking member 111 again; in this process, one side of the trigger component 103 applies force to one foot 1271 of the second knob 127, so that the second knob 127 is deflected, and the other foot 1272 of the second knob 127 toggles the sliding push block 104, so that the sliding push block 104 retracts and disengages from the energy storage slider 106; thereby unlocking the energy storage slider 106 and the trigger component 103; in this process, the energy storage slider 106 is driven to continue to move backward, and one side of the energy storage slider 106 applies force to one foot 1261 of the first knob 126, so that the first knob 126 is deflected, and the other foot 1272 of the first knob 127 62 toggles the locking slider 108, causing the locking slider 108 to retract and disengage from the ratchet on the first limit member, thereby unlocking the energy storage slider 106 and the handle housing, and under the action of the energy storage spring 119, it slides forward quickly and drives the puncture needle connector 208 to slide forward. The puncture needle connector 208 drives the suture fixing seat 211 and the guide rod 210 to slide forward until the puncture needle punctures the bottom. The energy storage slider 106, the puncture needle connector 208, the suture fixing seat 211, and the guide rod 210 all stop sliding and are in the second position. When sliding forward, the locking slider 108 contacts the slide groove of the upper housing 102 and falls back downward, returning to its initial position; the external force applied to the trigger component 103 is removed, and the trigger component 103 returns to its initial position under the action of the trigger spring 125; the locking member 111 returns to its initial position (locked position) due to the retraction of the unlocking pin 112 and the action of the spring 124.

[0189] Apply external force to the trigger component 103 again, the trigger component 103 slides backward, the sliding push block 104 drives the energy storage slider 106 to move backward again, the energy storage slider 106 drives the puncture needle connector 208 to slide backward, and the puncture needle connector 208 drives the suture fixing seat 211 and the guide rod 210 to slide backward, wherein, as Figure 40 and Figure 41 As shown, when the slot 2113 of the suture fixing seat 211 moves to engage with the suture reset pin 235, the suture fixing seat 211 stops moving backward, and the puncture needle connector 208 continues to retreat to complete the release of the distal anchor 300; Figure 42 and Figure 43 As shown, until the slope 2085 on the puncture needle connector 208 pushes up the suture reset pin 235, the suture reset spring 232 generates a backward elastic force on the suture fixing seat 211, releasing the suture fixing seat 211 to continue sliding backward and tightening the suture. At this time, the puncture needle is completely retracted and the distal anchor 300 is released; Figure 30As shown, the trigger component 103 moves backward to abut against the locking component 111 and pushes the limiting bolt 131, so that the large end of the limiting bolt 131 leaves the inside of the shearing trigger rod 113. The shearing trigger rod 113 is unlocked at this time. Under the action of external force, it can move upward and push the pushing locking component 215, causing it to rotate until the buckle of the pushing locking component 215 is disengaged from the pushing component 213. At this time, the tension spring pulls the pushing component 213 toward the shearing component 212 and pushes the proximal anchor 400 forward until the pushing component 213 collides with the support component 214, causing the support component 214 to be released. The support member 214 pivots to unlock the shearing member 212. Under the action of the tension spring 233, the shearing member 212 slides toward the pushing member 213, completing the shearing process. The external force on the shearing trigger lever 113 is now released, and the trigger lever spring 130 returns the trigger lever to its initial position. The external force on the trigger member 103 is now released, and the trigger member 103 returns to its initial position under the action of the trigger spring 125. The stopper 131 returns to its initial position under the action of the stopper spring 132, and the shearing trigger lever 113 is re-locked by the stopper 131. After replacing the magazine, the delivery system components have been reset, and the energy storage slide 106 is in the energy storage position. After loading a new magazine, the next round of puncture can be directly performed.
