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 thereof. Background Art

[0002] Benign prostatic hyperplasia (BPH) is one of the most common medical conditions affecting men, especially older men. The prostate gland continues to enlarge throughout a person's life. In some men, the prostatic capsule surrounding the prostate gland may prevent the prostate gland from further enlarging, which can cause the inner area of ​​the prostate gland to press against the urethra. This pressure on the urethra increases the resistance of urine to flow through the area of ​​the urethra surrounded by the prostate gland. As a result, the bladder must exert more pressure to force urine through the increased urethral resistance. Chronic overstraining can cause the muscle wall of the bladder to remodel and become stiffer. This increased urethral resistance and increased urine stream stiffness, along with hypertrophy of the bladder wall, can lead to a variety of lower urinary tract symptoms (LUTS), which can significantly reduce a patient's quality of life. These symptoms include a weak or intermittent urine stream when urinating, straining when urinating, hesitation before starting to urinate, a feeling that the bladder is not completely empty even after urinating, dribbling or leaking urine at the end of urination, increased frequency of urination, especially at night, and urgency to urinate. 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.) that can cause urinary retention. Although BPH is rarely life-threatening, it can lead to a number of clinical conditions, 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 therapy 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 have potential side effects, requiring the procedure to be performed in a surgical suite and then requiring the patient to be hospitalized. Methods of treating BPH with a lower risk of adverse effects are also associated with lower reductions in symptom scores. While some of these procedures can be administered with local analgesia in an office setting, patients do not experience immediate relief and in fact often experience worse symptoms for several weeks after the procedure until the body begins to heal. Additionally, many device methods require a catheter to be placed in the bladder, in some cases for several weeks. In some cases, catheterization is required because the treatment can actually cause an obstruction for a period of time after surgery, while in other cases, catheterization is required due to post-operative bleeding and potential occlusive clot formation. While drug therapies are easy to administer, the results are not ideal, require a significant amount of time to be effective, and often have undesirable side effects.

[0005] Prostate suspension is a minimally invasive surgery that uses a transurethral implant to dilate the blocked prostate urethra. The principle is to implant a miniature urethral suspension device to suspend and compress the obstructed prostate lobes, thereby dilating the blocked prostate urethra and improving the patient's obstruction symptoms. However, the existing surgical instruments used for prostate suspension are complex in structure and have many operating steps, which can easily lead to doctor's misoperation. Summary of the invention

[0018] Preferably, the first knob drives the locking slider to retract by turning the hinge pin on the locking slider; the second knob drives the sliding push block to retract by turning the protrusion provided on the sliding push block.

[0019] Preferably, the foot of the first knob in contact with the energy storage slider is shorter than the other foot in contact with the locking slider, and the foot of the second knob in contact with the trigger component is shorter than the other foot in contact with the sliding push block.

[0020] Preferably, the sliding push block can slide up and down on the trigger component, and the sliding push block is connected to the trigger component through a spring. In the natural state, the sliding push block is in an ejected state under the action of the spring force, so that it can be connected to the energy storage slider.

[0021] Preferably, the locking slider is installed on the energy storage slider in a manner that it can slide up and down, and a retaining block is installed on the energy storage slider in a manner that it can slide back and forth, one end of the retaining block is hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to one end of the locking slider through a hinge pin, and the other end of the locking slider can be ejected or retracted; the retaining block is connected to the energy storage slider through a retaining spring so that the retaining block gives the locking slider a tendency to maintain the ejection or retraction.

[0067] Embodiment 1:

[0068] 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.

[0069] like Figure 3 The magazine 200 shown includes:

[0070] A puncture needle tube 224, in which a puncture needle 221 capable of moving forward and backward 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;

[0071] A push-pull tube 225, in which a shear rod 228 and a push rod 227 capable of moving forward and backward are inserted, the proximal end of the push-pull tube 225 is fixedly connected to the front end of the magazine body, a proximal anchor 400 capable of moving forward and backward 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;

[0072] A puncture needle connector 208, the front portion of which is fixedly connected to the proximal end of the puncture needle 221, a suture 500 capable of moving forward and backward is inserted into the puncture needle 221, the proximal end of the suture 500 is fixedly connected to a suture fixing seat 211, the suture fixing seat 211 is mounted on the puncture needle connector 208 in a manner capable of sliding forward and backward, and the distal end of the suture 500 is fixedly connected to a distal anchor 300;

[0073] A shearing member 212 is installed in the magazine body in a manner that it can slide forward and backward. The shearing member 212 is fixedly connected to the proximal end of a shearing rod 228. The distal end of the shearing rod 228 is connected to a blade 223. The shearing rod 228 is driven by the shearing member 212 to pull the blade 223 backward to complete the shearing action;

[0074] A pushing component 213, which is installed in the magazine body in a manner that it can slide forward and backward, and 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 component 213. The shearing component 212 and the pushing component 213 are arranged front and back and connected by a tension spring 233 so as to pull the two toward each other;

[0075] 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.

[0076] like Figure 7 As shown, it also includes a support tube 226, the cross section of which is semicircular for matching with the endoscope tube, and the upper and lower sides thereof are respectively used to fix the puncture needle tube 224 and the push-pull tube 225. An arc-shaped channel connected to the distal end of the puncture needle tube 224 is provided in the head end component 222, so that the puncture needle 221 can be bent and extended from one side thereof for puncture.

[0077] This embodiment preferably also includes a stroke adjustment mechanism installed in the magazine body for blocking the puncture needle connector 208 from moving forward to control the puncture length.

[0078] This embodiment is preferred, as Fig. 9 and Fig.16 As shown, the stroke adjustment mechanism includes a stroke adjustment member 209, which is located in the slide groove of the magazine body and can slide forward and backward. The stroke adjustment member 209 is connected to the stroke adjustment cap 204 outside the magazine body through 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 forward and backward 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, so as to achieve puncture length adjustment, with a simple structure and convenient adjustment.

[0079] Further preferably, the stroke adjustment mechanism also includes a buffer pin 206 and an in-place prompting cap 203, the threaded rod 205 is a hollow rod with a central hole, the threaded rod 205 is hollowly sleeved on the buffer pin 206, the front end of the buffer pin 206 extends out of the threaded rod 205 and the stroke adjustment cap 204 and is fixedly connected to the in-place prompting cap 203, the rear end of the buffer pin 206 extends out of the threaded rod 205 and is given a buffering tendency by a spring, and the buffer pin 206 can slide back and forth in 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 hits the buffer pin and stops sliding after the buffer pin is fully pushed into the stroke adjustment member, and at the same time, the buffer pin pushes out the in-place prompting cap. The buffer pin can not only buffer and limit the puncture needle connector, but also facilitate the doctor to quickly determine whether the puncture is successful through the in-place prompting cap.

[0080] Further 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 part of the threaded rod 205 and can rotate relatively, the rear end of the stroke scale rod 207 passes through the through hole provided at the front end of the magazine body and is connected to the stroke adjustment member 209 in the magazine body, and scale marks corresponding to each puncture length are provided on the stroke scale rod 207. In this way, when the threaded rod moves forward and backward, the stroke scale screw rod moves with the scale, which is simple and intuitive, and convenient and quick to adjust the puncture length.

[0081] 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 and position the front end annular ring of the travel scale rod 207.

[0082] This embodiment is preferred, as Figure 4 and Figure 5As shown, the suture fixing seat 211 is installed in the inner cavity of the puncture needle connector 208, a guide rod 210 passes through the inner cavity of the puncture needle connector 208 and can slide forward and backward together with the suture fixing seat 211, and a spring 232 is sleeved on the guide rod 210 for giving the suture fixing seat 211 a tendency to move backward. The suture fixing seat 211 is sleeved on the guide rod 210. One end of the spring 232 abuts against the suture fixing seat 211 and the guide rod 210, and the other end of the spring 232 abuts against the puncture needle connector 208. A hook 2091 is provided on the stroke adjusting member 209, and the hook 2091 can cooperate with the groove 2101 set on the guide rod 210, thereby limiting the guide rod 210 from moving backward. In this way, after the puncture needle is released to complete the puncture, the guide rod and the suture fixing seat are restricted by the hook 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 to facilitate the release of the proximal anchor.

[0083] 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 on the suture fixing seat, and the suture support tube is crimped and fixed to the suture.

[0084] The shearing component 212, the pushing component 213, the supporting component 214 and their connection 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.

[0085] This embodiment is preferred, as Fig. 9 and Fig.19 As shown, the middle part of the support member 214 is hinged to the magazine body of the magazine through a hinge pin 230. A limiting column 2144 is provided below the front end 2141 of the support member 214, which can not only prevent the support member 214 from swinging excessively, but also a compression spring can be provided between it and the magazine body to prompt the support member 214 to return to the first position state. The rear end of the support member 214 includes a first limiting end 2142 and a second limiting end 2143, and the two limiting ends are V-shaped. The first limiting end 2142 is always blocked in front of the pushing component 213, so that when the pushing component 213 moves forward, it can timely push the support member 214 to swing and implement limiting.

[0086] In this embodiment, the support member 214 has an engagement position engaged with the shearing member 212, so that the support member 214 can prevent the shearing member 212 from sliding toward the pushing member 213, and has a disengagement position disengaged from the shearing member 212, so 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 to contact the support member 214 and cause the support member 214 to pivot and disengage from the shearing member 212.

[0087] 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.

[0088] The push shearing mechanism also includes a push locking member 215 disposed in the magazine body. When the push locking member 215 is in the initial position, it is connected to the push component 213, so that the push component 213 is locked and cannot be moved.

[0089] The push locking member can be a locking pin, a locking key or any other component or structure with a locking function.

[0090] This embodiment is preferred, as Fig.18 As shown, the push locking member 215 has a hook portion 2151, and the hook portion 2151 is engaged with the clamping portion on the push component 213 to achieve limited locking. The push locking member 215 also has a release portion 2151. The shear trigger rod 113 on the handle pushes the release portion 2151 to move the push locking member 215 left and right, thereby releasing the lock of the push component 213, and implementing suture fixation and cutting.

[0091] In this embodiment, three manual push knobs are slidably arranged on the outside of the magazine body, the first manual push knob 216 extends into the magazine body and is fixedly connected to the puncture needle connector 208, the second manual push knob 217 extends into the magazine body and is fixedly connected to the shearing component 212, and the third manual push knob 218 extends into the magazine body and is fixedly connected to the pushing component 213. In this way, when the internal structure of the magazine is stuck, the movement of the puncture needle connector, the pushing component and the shearing component in the magazine can be controlled by moving the manual push knob outside the magazine housing.

[0092] In this preferred embodiment, the magazine body 201 is fixed with a cover plate 202, and the two are fixedly connected by a buckle structure. The cover plate 202 is provided with three slide grooves, and three manual push buttons move forward and backward along the three slide grooves respectively, and the three manual push buttons are fixedly connected to the puncture needle connector, the shear component or the push component 213 by the buckle structure.

[0093] like Figure 2 The handle 100 shown comprises:

[0094] An energy storage slider 106, which is arranged in the handle housing in a manner that it can slide forward and backward and is connected to the puncture needle connector 208 in the magazine to move synchronously. The energy storage slider 106 is connected to the handle housing through an energy storage spring 119 so as to be given a tendency to move forward. The energy storage slider 106 is connected to the handle housing through a ratchet mechanism so as to be restricted from moving forward. When the energy storage slider 106 moves backward into position, the ratchet mechanism fails, so that the energy storage slider 106 moves forward quickly under the action of the energy storage spring;

[0095] A trigger component 103, which is arranged in the handle housing in a manner that it can slide forward and backward. The trigger component 103 is given a tendency to move forward by a trigger spring 125. A sliding push block 104 that can slide up and down is arranged 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 to its proper 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;

[0096] A locking piece 111 is arranged in the handle housing in a manner that it can slide up and down, and the locking piece 111 has a locking position and an unlocking position: when the locking piece 111 is in the locking position, the locking piece 111 can limit the trigger component 103 from moving backward, and the pawl mechanism of the energy storage slide 106 is effective, thereby limiting its forward movement; when the locking piece 111 is in the unlocking position, the trigger component 103 can move backward, thereby causing the pawl mechanism of the energy storage slide 106 to fail, and the sliding push block 104 is disengaged from the energy storage slide 106.

[0097] In this way, by arranging the locking part to cooperate with the trigger component to implement puncture, the risk of misoperation of the trigger single component is avoided, the operation is convenient, and the reliability is good.

[0098] In this embodiment, the handle housing includes a lower housing 101 and an upper housing 102 fixedly connected as one body, and a magazine compartment for placing a magazine is provided on the upper housing 102. A slide groove for a connecting column 2082 on the puncture needle connector 208 to pass through is provided on both the upper housing 102 and the magazine housing, and the connecting column 2082 is matched and connected 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.

[0099] 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.

[0100] In this embodiment, the cover plate 202 of the magazine is preferably provided with a locking button seat 219 and a locking button 220, the locking button seat 219 is fixedly connected or integrally formed with the cover plate 202, the locking button 220 is slidably mounted on the cover plate 202, the locking button seat 219 and the locking button 220 are abutted against each other by a compression spring 229 so that the locking button 220 is given a tendency to be ejected, and the locking button is fixedly connected to the magazine body 201 by a buckle structure when it is ejected. In this way, when an external force is applied to the locking button, the buckle structure of the locking button is retracted, and the magazine can be loaded into the magazine compartment of the handle, and 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 which time the magazine loading is completed, and the puncture needle connector is fixed with the energy storage slider.

[0101] 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.

[0102] In this embodiment, a guide shaft 105 is fixed on the lower housing 101, the energy storage slider 106 is sleeved on the guide shaft 105 and can slide forward and backward 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.

[0103] In this embodiment, the trigger component 103 slides forward and backward through the slides provided on the left and right sides and the slide grooves on the lower shell 101 and the upper shell 102. The trigger spring 125 is a tension spring, which is inserted into the through hole of the trigger component 103. The two ends of the tension spring are connected to the trigger component and the handle shell through connecting pins. In other embodiments, the trigger spring can also be a compression spring.

[0104] In this embodiment, the ratchet mechanism 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 ratchet mechanism fails; the retaining block 107 is connected to the energy storage slider 106 through the retaining spring 118 so that the retaining block 107 gives the locking slider 108 a tendency to maintain the push-out or retracted state. In this way, the structure is simple and reasonable, the energy storage slider has high reliability in unidirectional stepping motion, and the release is convenient.

[0105] Further preferably, the retaining block 107 is mounted on the energy storage slider 106 in a manner that allows it to slide forward and backward, and the locking slider 108 is mounted on the energy storage slider 106 in a manner that allows it to slide up and down, and the lower end of the locking slider 108 can be pushed out or retracted. In other embodiments, the locking slider can also be pushed out from the top or left and right sides of the energy storage slider, and cooperate with the corresponding ratchet on the handle housing to achieve unidirectional stepping motion.

[0106] 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 and maintained at the ejection position.

[0107] 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 may also be a tension spring.

[0108] In this embodiment, the locking slide 108 and the connecting rod 109 are hinged by a hinge pin 110, one end of which extends into a slide slot 1022 on the handle housing, and the slide slot 1022 is provided on the upper housing or the lower housing of the handle. The rear end of the slide slot 1022 is a lifting slope, and when the hinge pin 110 moves back to this point, it is lifted, and the locking slide 108 remains in a retracted state. The front part of the slide slot 1022 is provided with a descending slope 2092, and the descending slope 2092 is formed on the stroke adjustment member 209, and when the hinge pin 110 moves forward to this point, it is pressed down, and the locking slide 108 remains in an ejected state. In this embodiment, the slide slot 1022 is provided on the magazine compartment wall of the upper housing 102. The magazine compartment wall of the upper housing 102 is also provided with another slide slot 1021, so that the connecting column 2082 on the puncture needle connector 208 in the magazine can extend into the handle housing and connect with the energy storage slide.

[0109] In this embodiment, when the trigger member 103 moves backwards, the sliding push block 104 abuts against the sloped boss on the first stopper 1011 and moves downward to disengage from the energy storage slider 106. The first stopper 1011 is fixedly connected to the lower housing 101 or integrally formed.

[0110] In this embodiment, the locking member 111 is preferably connected to the lower housing 101 through a spring 124 so as to be given a tendency to move upward, and a locking boss 1111 for limiting the backward movement of the trigger member 103 is provided on the locking member 111, and the locking boss 1111 is arranged to protrude forward; an unlocking pin 112 capable of sliding forward and backward is installed on the locking member 111, and the unlocking pin 112 is pushed forward against the locking member 111 by the compression spring 121; 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 a locked position, and the locking boss 1111 is arranged to protrude forward; 111 can abut against the protrusion at the rear end of the trigger component 103 to limit the trigger component 103 from moving backward; 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 unlocking position, and the locking boss 1111 and the protrusion at the rear end of the trigger component 103 are misaligned up and down, so that the trigger component 103 is no longer limited from moving backward; when the trigger component 103 continues to move backward to its position, the protrusion at the rear end of the trigger component 103 pushes the unlocking pin 112 back, and the locking member 111 moves upward and resets to the locked position under the action of the spring. The limiting groove and the limiting protrusion on the second limiting member 1012 are arranged up and down and 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 fire the puncture and push back the unlocking pin to achieve re-locking, thereby avoiding the risk of misoperation of re-puncture.

[0111] In this embodiment, the locking member 111 is in the locked position in the initial state. A compression spring 121 and a retaining spring 120 are sleeved on the unlocking pin 112, and the retaining spring 120 is engaged in the retaining groove of the unlocking pin 112, and the two ends of the compression spring 121 are respectively against the locking member 111 and the retaining spring 120. In this way, the compression spring applies an outward thrust to the unlocking pin, so that the unlocking pin 112 is engaged in the limiting groove on the second limiting member 1012, so that the locking member 111 maintains the locked position.

[0112] In this embodiment, the handle is preferably provided with a shearing trigger rod 113 and an elastic stopper. The shearing trigger rod 113 is installed in the handle housing in a manner that it can slide up and down. The shearing trigger rod 113 is fixedly connected to a shearing push button 115 that is slidably arranged 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 to its position, it pushes the elastic stopper to unlock, so that the shearing trigger rod 113 can move up and down. The shearing trigger rod 113 pushes the release portion 2151 on the push locking component 215 to realize the left and right movement of the push locking component 215, thereby releasing the lock of the push component 213, and the push shearing mechanism implements the clamping and cutting of the suture. In this way, the push shearing mechanism can only be activated after the trigger component moves backward to its 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 misoperation in surgery.

[0113] Further preferably, the handle housing and the magazine body are provided with through holes through which the shear trigger rod 113 can pass. The upper part of the shear trigger rod 113 is U-shaped, one end of the upper part passes through the through hole and extends into the magazine to unlock the push locking member 215, and the other end of the upper part cooperates with the locking member 111 to limit the position: when the locking member 111 is in the unlocked position, the locking member 111 can limit 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 risk of surgery caused by the malfunction of the push shear mechanism during puncture.

[0114] Further preferably, the shear trigger rod 113 is installed in the 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 buckle structure. The elastic stopper is an elastic stop bar 114, which 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 to its position, 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, and the shear trigger rod 113 can move up and down.

[0115] The method of using the above-mentioned anchor delivery system is as follows:

[0116] 1) Applying external force to the trigger component 103 for the first time, the trigger component 103 drives the energy storage slider 106 and the puncture needle connector 208 to move backward to store energy;

[0117] 2) Press the locking member 111 to unlock;

[0118] 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 component 111 is reset, and the external force applied to the trigger component 103 is removed to reset it;

[0119] 4) Applying external force to the trigger component 103 again, the trigger component 103 drives the energy storage slider 106 and the puncture needle connector 208 to move backward to retract the puncture needle 221 and tighten the suture;

[0120] 5) Push the shear push button 115 to unlock the pushing component 213, which is pulled toward the shearing component 212, so that the proximal anchor is pushed out of the head end component 222 at the distal end of the puncture needle tube 224. The pushing component 213 is limited by the support component 214, unlocking the shearing component 212, and the shearing component 212 is pulled toward the pushing component 213, driving the shear rod and the blade to cut the suture.

[0121] The specific action coordination process is described as follows:

[0122] Apply external force to the locking push button, and the buckle structure of the locking push button retracts, so that the magazine can be loaded into the magazine compartment of the handle. Remove the external force applied to the locking push button, and the locking push 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.

[0123] 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. Fig. 9 shown.

[0124] like Fig.10 As shown in FIG. 1 , 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. Fig.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.

[0125] like Fig.12As 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, and 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. Fig.13 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 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 (slope boss) on the first limiter. 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. Fig.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 slot 1022 on the handle housing, as shown in FIG. Fig.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. Fig. 22 As shown, the puncture is completed, and the in-place prompt cap 203 is fully ejected, 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 located 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 in FIG. Fig.16 When the external force applied to the trigger component 103 is removed, the trigger component 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, and the binding force on the locking member 111 is lost. 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, forming a lock on the trigger component 103.

[0126] The trigger component 103 is subjected to external force again, and the trigger component 103 slides backward, and the sliding push block 104 drives the energy storage slider 106 to move backward again, and 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. Fig.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 backwards, and the puncture needle connecting member 208 continues to retreat to complete the release of the distal anchor until the trapezoidal boss 2081 on the puncture needle connecting member 208 lifts the hook of the stroke adjustment member 209, releasing the guide rod 210 to continue sliding backwards and tighten the suture. At this time, the puncture needle is completely retracted and the distal anchor is released. Fig.23 shown.

[0127] like Fig.18 and Fig.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 external force is continuously applied to the trigger member 103, 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, as shown in FIG. Fig. 20 As shown, at this time, the tension spring 233 pulls the pushing component 213 toward the shearing component 212, pushing the proximal anchor forward until the pushing component 213 collides with the support member 214, causing the support member 214 to pivot to unlock the shearing component 212, as shown in FIG. Fig.21 As shown, under the action of the tension spring, the shearing component 212 slides in the direction of the pushing component 213, driving the shearing rod to complete the shearing. If the structure is stuck during this process and the action cannot be completed smoothly, it can be manually operated by manually pushing and twisting. Remove the thrust on the shearing push button 115, it resets to the first position under the action of the compression spring, remove the external force on the trigger component 103, it returns to the first position again under the action of the tension spring, and at this time, the energy storage slider 106 stays in the second position under the action of the locking slider 108, maintaining the energy storage state, and the elastic stop bar 114 loses the external force and returns to its original state, and continues to lock the shearing trigger rod 113.

[0128] After that, the magazine is replaced, the handle components have been reset, the energy storage slider 106 is in the energy storage position, and the next round of puncture can be directly performed after loading a new magazine. Fig.24 shown.

[0129] Embodiment 2:

[0130] The difference between this embodiment and embodiment 1 is that this embodiment newly provides an unlocking structure of an energy storage slider inside the handle.

[0131] like Fig.25 A handle of an anchor delivery system is shown, comprising:

[0132] a handle housing;

[0133] An energy storage slider 106 is arranged in the handle housing in a manner that it can slide back and forth and is connected to the puncture needle connector 208 in the magazine and moves synchronously. The energy storage slider 106 is connected to the handle housing through an energy storage spring 119 so as to be given a tendency to move forward. A locking slider 108 that can be pushed out or retracted is slidably arranged on the energy storage slider 106: when the locking slider 108 is pushed out, it cooperates with the ratchet on the handle housing to limit the forward movement of the energy storage slider 106; when the energy storage slider 106 moves backward into position, the locking slider 108 retracts and disengages from the ratchet on the handle housing;

[0134] A trigger component 103 is arranged in the handle housing in a manner that it can 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 slidingly arranged on the trigger component 103, and 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 place, the sliding push block 104 is disconnected from the energy storage slider 106.

[0135] A first knob 126, which is installed in the handle housing in a deflectable manner. When the energy storage slider 106 moves backward to a position, the energy storage slider 106 applies force to one leg 1261 of the first knob 126, so that the first knob 126 is deflected, and the other leg 1262 of the first knob 126 moves the locking slider 108, so that the locking slider 108 is retracted and disengaged from the ratchet on the handle housing; thereby unlocking the energy storage slider 106 and the handle housing;

[0136] A second knob 127 is installed in the handle housing in a deflectable manner. When the trigger component 103 moves backward into position, the trigger component 103 applies force to one foot of the second knob 127 to deflect the second knob 127. The other foot of the second knob 127 moves the sliding push block 104 to disengage the sliding push block 104 from the energy storage slider 106, thereby unlocking the energy storage slider 106 and the trigger component 103.

[0137] As can be seen from Example 1, the trigger component 103 drives the energy storage slider 106 to move and store energy through the sliding push block 104, and the energy storage slider 106 is locked with the handle housing through the locking slider 108 after storing energy. When the energy storage slider 106 is unlocked for firing and puncturing, the unlocking sliding push block 104 and the locking slider 108 need to be moved in time. In Example 1, the locking slider 108 is retracted through the slope, the friction force is too large, and the slope distance is too long, resulting in a long distance for the energy storage slider to move backward, a large amount of spring compression, and thus a large force transmitted to the trigger, which is more laborious for the operator. In Example 1, the sliding push block 104 on the trigger component can be connected or disconnected with the energy storage slider 106, and the way of disconnection is to move the sliding push block downward through the slope boss, and this way has a relatively large friction force.

[0138] This embodiment provides a new method, which uses a knob to unlock. One side of the energy storage slider applies force to the knob, forcing the knob to deflect. The other side of the knob pushes the locking slider pin upward to retract the locking slider upward. At the same time, one side of the trigger applies force to the knob, causing the knob to deflect. The other side of the knob pushes the sliding push block downward, and the sliding push block can be separated from the energy storage slider. At this time, the energy storage slider is unlocked. In this way, the locking slider is retracted and the sliding push block is moved downward by the deflection of the knob, thereby unlocking the energy storage slider. The friction is small, the movement distance of the energy storage slider is short, and it is easier for the operator.

[0139] In this embodiment, the first knob 126 and the second knob 127 are preferably disposed in the handle housing in a manner that allows them to rotate along a central axis.

[0140] 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 being deflected; 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 being deflected.

[0141] 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 disposed on the sliding push block 104.

[0142] 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 component 103 that is shorter than the other leg 1272 in contact with the sliding push block 104. In this way, unlocking is faster and the operation is more convenient and easy.

[0143] The other structures of the handle in this embodiment are the same as those in Embodiment 1. This embodiment also discloses an anchor member delivery system using the handle, and the magazine and other parts of the anchor member delivery system are the same as those in Embodiment 1.

[0144] The unlocking process of this embodiment is described as follows:

[0145] The initial state of the handle is Fig.26 As shown in FIG. 1 , when an external force is applied to the trigger component 103, it slides backward from the initial position along the slide groove, and drives the energy storage slider 106 to move backward at the same time through the sliding push block 104. When the energy storage slider 106 reaches the energy storage position, the locking slider 108 engages with the ratchet structure in the lower housing 101, as shown in FIG. Fig. 27 As shown, in this state, the compression spring has completed accumulating mechanical energy, one side of the energy storage slider 106 contacts with one foot 1261 of the first knob 126, and one side of the trigger component 103 contacts with one foot 1271 of the second knob 127.
