[0001] This application is the following application

[0002] Application number: 202311322375.5

[0003] Application date: October 12, 2023 Application name: Anchor delivery system and method thereof, handle and magazine

[0004] Divisional application. Technical Field

[0005] The present invention belongs to the technical field of medical devices, and in particular relates to an anchor delivery system, a method thereof, and a handle. Background Art

[0006] 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 overuse can cause the bladder's muscle wall to remodel and become stiffer. This increased urethral resistance, increased urine stream hardness, and 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 urine at the end of urination, increased urinary frequency, especially at night, and urgency. In addition to patients with BPH, LUTS may also be present in patients with prostate cancer, prostate infections, and long-term use of certain medications (e.g., ephedrine, pseudoephedrine, phenylpropanolamine, antihistamines such as diphenhydramine, chlorpheniramine, etc.), which can cause urinary retention. Although BPH is rarely life-threatening, it can lead to a number of clinical symptoms, including urinary retention, renal insufficiency, recurrent urinary tract infections, incontinence, hematuria, and bladder stones.

[0007] 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.

[0008] 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.

[0009] 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:

[0010] 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.

[0011] 2. The structure is complex and there are many operating steps, which may easily lead to doctor's misoperation.

[0012] 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

[0013] In order to solve the above-mentioned technical problems, one of the purposes of the present invention is to provide an anchor delivery system and a handle thereof, which are provided with a locking structure to facilitate surgical operations and reduce the risk of surgical errors.

[0014] A second object of the present invention is to provide an anchor delivery method for the above-mentioned anchor delivery system.

[0015] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0016] A handle for an anchor delivery system includes: an energy storage slider, which is arranged in a handle housing in a manner that allows it to slide back and forth and is connected to a puncture needle connector in a magazine for synchronous movement. The energy storage slider is connected to the handle housing via an energy storage spring, thereby imparting a tendency to move forward; a trigger component, which is arranged in the handle housing in a manner that allows it to slide back and forth; and a locking member, which is arranged in the handle housing in a manner that allows it to slide up and down. The locking member has a locked position and an unlocked position: when the locking member is in the locked position, the locking member can restrict the trigger component from moving backward, and the pawl mechanism of the energy storage slider is effective, thereby restricting its forward movement; when the locking member is in the unlocked position, the trigger component can move backward, thereby causing the pawl mechanism of the energy storage slider to be disabled and the sliding push block to disengage from the energy storage slider. In this way, by arranging the locking member and the trigger component to cooperate to perform puncture, the risk of misoperation caused by the trigger component firing alone is avoided, and the operation is convenient and the reliability is good.

[0017] Preferably, the handle shell includes a lower shell and an upper shell fixedly connected as one, and the upper shell is provided with a magazine compartment for placing the magazine; the upper shell is provided with a slide groove for the connecting column to pass through, and the energy storage slider and the puncture needle connector are connected by the connecting column to achieve synchronous movement.

[0018] Preferably, the trigger component slides back and forth by cooperating with the slides on the lower shell and the upper shell through the slides provided on the left and right sides. The trigger spring is a tension spring, which is passed through the through hole of the trigger component. The two ends of the tension spring are respectively connected to the trigger component and the handle shell through connecting pins.

[0019] As preferred, the locking member is connected to the lower shell body by a spring so as to be given a tendency to move upward, and the locking member is provided with a locking boss for limiting the backward movement of the trigger member, and the locking boss is protruding forward; an unlocking pin that can slide back and forth is installed on the locking member, and the unlocking pin is pushed forward by the compression spring and the locking member; when the unlocking pin is pushed forward and inserted into the limiting groove on the second limiting member, the locking member is in the locked position, and the locking boss can be pushed against the protrusion at the rear end of the trigger member, thereby limiting the backward movement of the trigger member; when the unlocking pin is pushed forward and against the limiting protrusion on the second limiting member, the locking member is in the unlocked position, and the locking boss and the protrusion at the rear end of the trigger member are misaligned up and down, thereby no longer limiting the backward movement of the trigger member; when the trigger member continues to move backward into place, the protrusion at the rear end of the trigger member pushes the unlocking pin back, and the locking member moves upward and resets to the locked position under the action of the spring; the second limiting member is fixedly connected to the lower shell body or is integrally formed; the locking member is in the locked position in the initial state. 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.

[0020] Preferably, the limiting groove and the limiting protrusion on the second limiting member are arranged up and down and transitioned by a slope therebetween.

[0021] Preferably, a shear trigger rod and an elastic limiter are further provided. The shear trigger rod is installed in the handle housing in a manner that allows it to slide up and down. The shear trigger rod is fixedly connected to 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 pushes the release portion on the push locking component to achieve left and right movement of the push locking component, thereby releasing the lock of the push component, and the push shear mechanism clamps and cuts the suture. In this way, the push shear 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.

[0022] Preferably, both the handle housing and the magazine housing are provided with through-holes through which the shear trigger rod passes. The upper portion of the shear trigger rod is U-shaped, with one end extending through the through-hole into the magazine to unlock the push-locking member, while the other end cooperates with the locking member to limit position: when the locking member is in the unlocked position, the locking member can restrict the upward movement of the shear trigger rod; when the locking member is in the locked position, the shear trigger rod is unrestricted. 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.

[0023] Preferably, the shear trigger rod is installed in the slide groove formed by the upper shell and the lower shell and can slide up and down. It is connected to the shear push button through a snap structure. The elastic limiter is an elastic stop bar, which is V-shaped. One end of the elastic stop bar is fixed in the slot of the lower shell, and the other end of the elastic stop bar is inserted into the slot on the shear trigger rod. When the shear trigger rod is in the initial position, the elastic stop bar contacts the boss of the lower shell, locking the shear trigger rod so that it cannot move; when the trigger component moves back into place, the elastic stop bar is compressed, and the other end of the elastic stop bar withdraws from the slot on the shear trigger rod, and the shear trigger rod can move up and down.

[0024] An anchor delivery system adopts the handle for the anchor delivery system as described above.

[0025] An anchor delivery method uses an anchor delivery system as described above.

[0026] The present invention adopts the above technical solution and is provided with a locking structure. By setting a locking member and a trigger component to cooperate in puncture, the risk of misoperation caused by the trigger component alone is avoided. The device has good reliability, facilitates surgical operation, and reduces the risk of misoperation. The device structure of the present invention is more reasonable and simple, easy to operate, less prone to errors, and has better reliability. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] For the convenience of expression, the present invention is 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.

[0061] Example 1:

[0062] 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.

[0063] like Figure 3 The magazine 200 shown includes:

[0064] 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;

[0065] 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;

[0066] 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.

[0067] 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;

[0068] 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;

[0069] 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.

[0070] like Figure 7 As shown, it also includes a support tube 226, which has a semicircular cross-section for mating with the endoscope tube. 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] The push locking member can be a locking pin, a locking key or other parts or structures with a locking function.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] like Figure 2 The handle 100 shown includes:

[0088] 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 moves 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 pawl mechanism, thereby restricting forward movement. When the energy storage slider 106 moves backward into position, the pawl mechanism is disabled, thereby allowing the energy storage slider 106 to move forward rapidly under the action of the energy storage spring;

[0089] 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 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 position, the sliding push block 104 is disconnected from the energy storage slide 106, and the trigger component 103 cannot drive the energy storage slide 106 to move.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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 formed integrally 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 is fixedly connected to the magazine housing 201 via a snap-fit structure. Thus, when an external force is applied to the locking button, the snap-fit 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, completing magazine loading. The puncture needle connector is then fixedly engaged with the energy storage slider.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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 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 the suture is clamped and cut, thereby avoiding the risk of surgical misoperation.

[0107] 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.

[0108] 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.

[0109] The present invention also discloses a method for delivering an anchor member, which uses the above-mentioned anchor member delivery system and includes the following steps:

[0110] 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;

[0111] 2) Press the locking member 111 to unlock;

[0112] 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;

[0113] 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;

[0114] 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.

[0115] The specific action coordination process of the above-mentioned anchor delivery system is described as follows:

[0116] 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.

[0117] 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.

[0118] like Figure 10As 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 11 As 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.

[0119] 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 22As 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 16 When 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.

[0120] 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.

[0121] 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 21 As 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.

[0122] 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.
