Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a medical penetrating suture device and its usage method. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Through-the-loop sutures, a classic and commonly used suturing technique in the field of surgery, have been widely and successfully applied in various surgeries across multiple departments, including general surgery, orthopedics, and obstetrics and gynecology, thanks to their core advantages of achieving precise tissue alignment and promoting postoperative healing. They play a crucial role in ensuring surgical outcomes and patient recovery. However, when the surgical setting shifts to extremely confined spaces such as the nasal cavity, the application of this suture technique faces significant limitations, particularly in nasal septum surgery, a common procedure in otolaryngology.

[0004] The nasal septum has a unique anatomical structure, consisting of two layers of mucosa sandwiching a layer of cartilage. This three-layered structure of "mucosa-cartilage-mucosa" determines the critical requirements for its postoperative recovery. It is essential to ensure that the mucosa on both sides can be precisely repositioned and closely aligned to avoid problems such as mucosal misalignment and poor healing, thereby guaranteeing the restoration of normal nasal physiological function. Based on this requirement, current clinical practice mainly employs two methods for mucosal repositioning and alignment after nasal septum surgery, but both have significant limitations: The first method is nasal packing, which is more common in clinical practice. Gelatin sponge is often used as the packing material to completely seal both nostrils, with a packing period typically set at 3-7 days. From a mechanism of action perspective, the packing material applies continuous pressure to the mucosa on both sides of the nasal septum, which can help maintain the mucosa in its repositioned state to some extent, providing a relatively stable environment for mucosal healing. However, in practical application, the core drawback of this method is the difficulty in precisely controlling the uniformity of packing: if the packing force is too great or the density is too high, it can obstruct local blood circulation in the mucosa, leading to insufficient oxygen and nutrient supply to the tissues, easily causing ischemic necrosis of the mucosa; if the packing force is too light or the density is insufficient, it cannot provide effective support and fixation, making hematoma more likely to occur in the nasal septum area postoperatively, and the open wound environment increases the risk of bacterial infection. Furthermore, bilateral nasal packing directly affects the patient's normal respiratory function, forcing the patient to breathe through the mouth, which can lead to a series of uncomfortable symptoms such as headache, dizziness, nausea, and irritability, significantly increasing the patient's postoperative suffering. More importantly, the packing needs to be removed after the packing cycle is over. This procedure not only causes the patient to suffer severe pain again, but may also cause traction and friction on the partially healed mucosa during the removal process, leading to secondary tearing of the mucosa and seriously affecting the postoperative recovery process.

[0005] The second method is the surgical transconjunctival suture. From a treatment perspective, this method uses sutures to fix the three layers of the nasal septum, achieving precise mucosal alignment. Furthermore, it eliminates the need for nasal packing after suturing, allowing the patient's nasal cavity to remain open and normal breathing function unaffected. This effectively avoids the discomfort associated with packing, significantly reducing postoperative pain. However, this method also faces significant challenges: because the surgical space for septoplasty is limited to the narrow nostrils, the surgeon must coordinate endoscopic observation and suture instrument manipulation within a very small field of vision and operating range. This requires not only ensuring precise suture placement but also performing complex operations such as suture threading and knotting, making the procedure extremely difficult. This process is often lengthy, typically taking 2-3 hours to complete a transconjunctival suturing surgery. This prolonged, meticulous operation places extremely high demands on the surgeon's professional skills, hand stability, and physical stamina, increasing the workload and potentially leading to decreased surgical precision and affecting the outcome due to fatigue.

[0006] In summary, current clinical methods for mucosal repositioning and apposition in confined spaces, such as nasal septum surgery, have significant shortcomings and cannot simultaneously meet the clinical needs of "convenient operation, minimal patient discomfort, and high surgical efficiency".

A handle is provided at the lower part of the outer casing, and a number of arc-shaped grooves are provided at intervals at one end of the handle.

[0017] A method of using a medical penetrating suture device includes the following steps: First, install the upper support mechanism and the lower support mechanism on the mounting block, and then pull the locking pin out of the locking groove on the first moving rod; Once completed, gently pull the trigger to move it. The movement of the trigger causes the sector gear to rotate, which in turn causes the pinion to rotate. The pinion then causes the second connecting shaft to rotate, which in turn causes the cam to rotate. This causes one end of the lower support rod to move downward and the other end to move upward, thereby lifting the lower support mechanism upward and clamping the nasal mucosa. At the same time, the trigger drives the second connecting rod to move, and the second connecting rod drives the first lever to move under the action of the fourth connecting shaft, thereby causing the counting disk to rotate to realize counting; when the counting disk rotates, it causes the second lever to move, and the second lever rotates through the sixth connecting shaft, thereby compressing the lever spring. The front end of the second lever moves down to separate the first and second lever blocks, thereby releasing the limit on the first connecting rod and activating the first moving rod. The first moving rod, under the tension of the first spring, drives the first slider to move, causing the first slider to move toward the limiting mechanism. This causes the limiting block of the limiting mechanism to be pressed into the limiting mounting plate, and the limiting spring to be compressed. At this time, the first slider moves from the rear of the limiting mechanism to the front of the limiting mechanism. This releases the second slider, which, under the tension of the second spring, drives the second slider, the first moving rod, and the second lever to move backward until the second lever moves to the front end of the second lever, so that the second lever and the first lever are tightly pressed together again, and the first moving rod is limited again. When the first moving rod moves forward, it pushes the steel belt push rod of the upper support mechanism, which in turn pushes the steel belt to move in the steel belt slide, thereby causing the steel belt to drive the puncture needle to puncture. During puncture, the barbed thread on the paper tape is hung in the puncture needle groove, and then the puncture needle is brought into the nasal mucosa to achieve suturing. After puncture, it is quickly withdrawn. Meanwhile, the push block on the steel strip push rod moves towards the arc-shaped block, and the push block contacts the arc-shaped block, causing the arc-shaped block to rotate on the seventh connecting shaft. At this time, the first stop block is raised, the second stop block is lowered, the push spring is compressed, releasing the limit on the push gear, and then the push gear rotates under the action of the disc spring, which in turn drives the eighth connecting shaft to rotate. The eighth connecting shaft drives the second paper belt pulley to rotate, the second paper belt pulley drives the paper belt to move, and the paper belt drives the first paper belt pulley to rotate, thus feeding the barbed wire to the required position, so that the barbed wire can be hooked in the puncture needle groove at the front end of the puncture needle. After puncture, the steel strip push rod is pulled back to its original position by the reset spring; the push spring pulls the arc-shaped block to rotate along the seventh connecting shaft, the first stop block moves downward, and the push gear is limited again to ensure that the push gear rotates a distance of one tooth. The second stop block moves upward to reset, thus facilitating the next wire feeding. The counting, puncture needle insertion, and upward movement of the lower support mechanism are all completed simultaneously, thereby achieving clamping and puncture while counting, ensuring the stability of the barbed puncture and the accuracy of the counting; Then, continue to pull the trigger. The trigger moves the push rod connecting block, which in turn moves the push rod connecting block, which in turn moves the slider push rod toward the second slider, thus pushing the second slider forward until it stops moving in front of the limiting mechanism. The limiting mechanism then limits the second slider again, thereby compressing the first spring and charging it, which facilitates the next puncture and suturing.

[0018] Compared with the prior art, the advantages and positive effects of this invention are: This invention uses connecting blocks arranged vertically at one end of the outer shell to detachably install the upper and lower support mechanisms. The upper support mechanism has an observation port at the front of the outer shell, which allows real-time observation of the internal puncture needle status, ensuring that the puncture needle is accurately aligned with the suture position in confined spaces such as the nasal cavity. The steel belt slide inside the upper support shell provides stable guidance for the steel belt. When the trigger of the second suture mechanism is pulled, the trigger drives the sector gear to rotate around the first connecting shaft. The sector gear meshes with the pinion, causing the second connecting shaft to rotate, which in turn drives the cam to push the lower support rod to rotate around the third connecting shaft. The other end of the lower support rod lifts the lower support mechanism, working with the upper support mechanism to achieve stable clamping of the mucosa. At the same time, the first moving rod pushes the steel belt push rod under the action of the first spring, causing the steel belt to carry the puncture needle along the steel belt slide to extend and puncture. The entire process is achieved through the coordinated transmission of the mechanical structure, eliminating the need for complex manual operation in confined spaces, greatly reducing the difficulty of operation, and achieving precise penetrating suture.

[0019] This invention employs a suture method where the suture delivery assembly within the upper support mechanism works in conjunction with the puncture needle. The arc-shaped block in the suture delivery assembly is pushed by a pusher block, causing the pusher gear to rotate. This, in turn, causes the eighth connecting shaft to rotate the second paper belt pulley, which in turn pulls the paper belt around the first paper belt pulley, delivering the barbed suture on the paper belt to below the puncture needle. The puncture needle groove on the puncture needle can catch the barbed suture, allowing the barbed suture to be directly inserted into the mucosal tissue during puncture to complete the suture, eliminating the need for nasal packing as in traditional methods. After puncture, the steel belt pusher rod, under the action of a return spring, retracts the steel belt and the puncture needle. The pusher plate, under the action of a pusher spring, resets, causing the gear pusher rod and the pusher gear to rotate in the opposite direction, returning the paper belt to its position for the next suture delivery. The entire suture process does not require closing the nasal cavity, avoiding breathing difficulties and mucosal ischemia and necrosis caused by packing. It also eliminates the need for subsequent removal of packing material, avoiding traction damage to the mucosa during removal and significantly reducing patient discomfort.

[0020] When the trigger of this invention is pulled, the trigger not only drives the lower support mechanism to clamp the mucosa via the sector gear and pinion, but also drives the push rod connecting block and the slider to move via the first connecting rod. Simultaneously, the second connecting rod in the middle of the first connecting rod drives the first lever via the fourth connecting shaft. The first lever causes the counting disc to rotate around the fifth connecting shaft to achieve suture counting. When the counting disc rotates, it squeezes the second lever, causing the second lever to rotate around the sixth connecting shaft and compress the lever spring. The first lever block at the upper end of the second lever separates from the second lever block on the first moving rod, releasing the pressure on the first moving rod. The first moving rod, under the action of the first spring, pushes the steel strip push rod to complete the puncture and suture delivery. After puncture, the trigger is held tight, and the slider push rod pushes the second slider forward. The second slider compresses the second spring and triggers the limiting mechanism. The limiting block of the limiting mechanism pops out under the action of the limiting spring, limiting the second slider and compressing and charging the first spring to prepare for the next puncture. In the whole process, the clamping, puncture, suture delivery, counting, and charging actions are completed synchronously through the linkage between the structures, without the need for step-by-step manual operation, effectively shortening the operation time and improving the operation efficiency.

[0023] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0024] Currently, there are two main approaches used in clinical practice for mucosal repositioning and repositioning after septoplasty, but both have significant limitations: The first method is nasal packing, which is more common in clinical practice. Gelatin sponge is often used as the packing material to completely seal both nostrils, with a packing period typically set at 3-7 days. From a mechanism of action perspective, the packing material applies continuous pressure to the mucosa on both sides of the nasal septum, which can help maintain the mucosa in its repositioned state to some extent, providing a relatively stable environment for mucosal healing. However, in practical application, the core drawback of this method is the difficulty in precisely controlling the uniformity of packing: if the packing force is too great or the density is too high, it can obstruct local blood circulation in the mucosa, leading to insufficient oxygen and nutrient supply to the tissues, easily causing ischemic necrosis of the mucosa; if the packing force is too light or the density is insufficient, it cannot provide effective support and fixation, making hematoma more likely to occur in the nasal septum area postoperatively, and the open wound environment increases the risk of bacterial infection. Furthermore, bilateral nasal packing directly affects the patient's normal respiratory function, forcing the patient to breathe through the mouth, which can lead to a series of uncomfortable symptoms such as headache, dizziness, nausea, and irritability, significantly increasing the patient's postoperative suffering. More importantly, the packing needs to be removed after the packing cycle is over. This procedure not only causes the patient to suffer severe pain again, but may also cause traction and friction on the partially healed mucosa during the removal process, leading to secondary tearing of the mucosa and seriously affecting the postoperative recovery process.

[0025] The second method is the surgical transconjunctival suture. From a treatment perspective, this method uses sutures to fix the three layers of the nasal septum, achieving precise mucosal alignment. Furthermore, it eliminates the need for nasal packing after suturing, allowing the patient's nasal cavity to remain open and normal breathing function unaffected. This effectively avoids the discomfort associated with packing, significantly reducing postoperative pain. However, this method also faces significant challenges: because the surgical space for septoplasty is limited to the narrow nostrils, the surgeon must coordinate endoscopic observation and suture instrument manipulation within a very small field of vision and operating range. This requires not only ensuring precise suture placement but also performing complex operations such as suture threading and knotting, making the procedure extremely difficult. This process is often lengthy, typically taking 2-3 hours to complete a transconjunctival suturing surgery. This prolonged, meticulous operation places extremely high demands on the surgeon's professional skills, hand stability, and physical stamina, increasing the workload and potentially leading to decreased surgical precision and affecting the outcome due to fatigue.

[0026] In summary, current clinical methods for mucosal repositioning and apposition in confined spaces, such as nasal septum surgery, have significant shortcomings and cannot simultaneously meet the clinical needs of "convenient operation, minimal patient discomfort, and high surgical efficiency".

A cam 230 is located at one end of the second connecting shaft 207 and sleeved on it. A lower support rod 209 is located at the lower end of the cam 230. One end of the rod 209 is in close contact with the cam 230. A third connecting shaft 208 is provided in the middle of the lower support rod 209. The other end of the lower support rod 209 is in close contact with the lower support mechanism. A first connecting rod 210 is provided at one end of the sector gear 202. The first connecting rod 210 is fixedly connected to the trigger 201. One end of the first connecting rod 210 is fixedly connected to the push rod connecting block 211. A slider pushing rod 212 is symmetrically provided at one end of the push rod connecting block 211 and is fixedly connected to the slider pushing rod 212. A pushing assembly is provided at the upper end of the slider pushing rod 212. The pushing assembly includes a first moving rod 216. A second slider 215 is sleeved on one end of the first moving rod 216. Second moving rods 218 are provided at both ends of the second slider 215. A second spring 219 is provided on the second moving rod 218. A first slider 214 is provided at one end of the second slider 215.

[0028] Specifically, the upper and lower support mechanisms are detachably installed via connecting blocks 4 arranged vertically at one end of the outer shell 3. The upper support shell 101 of the upper support mechanism has an observation port 107 at the front, which allows real-time observation of the internal puncture needle 122 to ensure that the puncture needle 122 is accurately aligned with the suture position in confined spaces such as the nasal cavity. The steel belt slide 110 inside the upper support shell 101 provides stable guidance for the steel belt 111. When the trigger 201 of the second suture mechanism 2 is pulled, the trigger 201 drives the sector gear 202 to rotate around the first connecting shaft 203, and the sector gear 202 meshes with the pinion. 206 causes the second connecting shaft 207 to rotate, which in turn drives the cam 230 to push the lower support rod 209 to rotate around the third connecting shaft 208. The other end of the lower support rod 209 lifts the lower support mechanism, which works with the upper support mechanism to achieve stable clamping of the mucosa. At the same time, the first moving rod 216 pushes the steel belt push rod 106 under the action of the first spring 217, so that the steel belt 111 drives the puncture needle 122 to extend and puncture along the steel belt slide 110. The whole process is achieved through the coordinated transmission of the mechanical structure, eliminating the need for complex manual operation in a confined space, greatly reducing the difficulty of operation, and achieving precise penetrating suturing.

[0029] The suture method employs a suture feeding assembly within the upper support mechanism that works in conjunction with the puncture needle 122. The arc-shaped block 113 in the suture feeding assembly is pushed by the push block 109, which in turn rotates the push gear 117. This causes the eighth connecting shaft 118 to drive the second paper belt pulley 121 to rotate, thereby pulling the paper belt 120 around the first paper belt pulley 119. The barbed suture 9 on the paper belt 120 is then delivered to the area below the puncture needle 122. The puncture needle groove 1221 on the puncture needle 122 can catch the barbed suture 9, allowing it to be directly inserted into the mucosal tissue during puncture to complete the suture, eliminating the need for a traditional suture feeding mechanism. The nasal cavity is packed in the same way as in the traditional method; after puncture, the steel belt push rod 106 drives the steel belt 111 and the puncture needle 122 to retract under the action of the reset spring 108, and the push plate 115 is reset under the action of the push spring 113, which drives the gear push rod 116 and the push gear 117 to rotate in opposite directions, so that the paper tape 120 returns to its position to prepare for the next suture delivery. The entire suturing process does not require closing the nasal cavity, avoiding breathing difficulties and mucosal ischemia and necrosis caused by packing, and also eliminates the need to remove the packing material afterward, avoiding traction damage to the mucosa during removal, and significantly reducing patient pain.

[0030] When the trigger 201 is pulled, the trigger 201 not only drives the lower support mechanism to clamp the mucosa through the sector gear 202 and the pinion 206, but also drives the push rod connecting block 211 and the slider push rod 212 to move through the first connecting rod 210. At the same time, the second connecting rod 221 in the middle of the first connecting rod 210 drives the first lever 223 through the fourth connecting shaft 222. The first lever 223 drives the counting disk 224 to rotate around the fifth connecting shaft 225 to realize suture counting. When the counting disk 224 rotates, it squeezes the second lever 226, causing the second lever 226 to rotate around the sixth connecting shaft 227 and compress the lever spring 228. The first lever block 231 at the upper end of the second lever 226 separates from the second lever block 232 on the first moving rod 216. The first moving rod 216 is released from its limit, and under the action of the first spring 217, the first moving rod 216 pushes the steel strip push rod 106 to complete the puncture and suture delivery. After puncture, the trigger 201 is held tight, and the slider push rod 212 pushes the second slider 215 forward. The second slider 215 compresses the second spring 219 and triggers the limiting mechanism 220. The limiting block 2203 of the limiting mechanism 220 pops out under the action of the limiting spring 2202, limiting the second slider 215 and compressing and energizing the first spring 217 to prepare for the next puncture. In the whole process, the clamping, puncture, suture delivery, counting, and energizing actions are completed synchronously through the linkage between the structures, without the need for step-by-step manual operation, effectively shortening the operation time and improving the operation efficiency.

[0031] Specifically, this invention features a split gun body, a suture needle 122, a built-in barbed suture compartment 9, a synchronous counter, and rechargeable technology. It allows for rapid suturing of the nasal septum using common barbed suture 9. It is convenient and efficient, reducing suturing time from 2-3 hours to 1-2 minutes, significantly reducing the workload of doctors. The gun tip is much smaller than a suture needle, allowing access to deeper areas and a wider suturing range. It can be used as a single unit, suitable for special scenarios such as nasal clip suturing. It allows for opening the nasal cavity, reducing patient discomfort. The split structure and barbed suture 9 reduce medical insurance costs and the burden on patients. Furthermore, the invention has fewer components, and the split structure significantly reduces manufacturing costs for enterprises.

[0032] like Figure 9 , Figure 10 , Figure 11 as well as Figure 12 As shown, the wire feeding assembly includes a seventh connecting shaft 112, which is fixedly connected to the inner wall of the upper support housing 101. An arc-shaped block 113 is provided on the seventh connecting shaft 112, and the arc-shaped block 113 is rotatably connected to the seventh connecting shaft 112. A first stop 114 is provided at one end of the lower part of the arc-shaped block 113, and a second stop 115 is provided at the other end of the lower part. The first stop 114 and the second stop 115 are fixedly connected to the arc-shaped block 113.

[0033] A push gear 117 is provided at the lower end of the arc-shaped block 113. The first stop block 114 and the second stop block 115 are close to the teeth of the push gear 117. The push gear 117 is provided on the eighth connecting shaft 118. The eighth connecting shaft 118 is fixedly connected to the push gear 117. The end of the eighth connecting shaft 118 is movably connected to the inner wall surface of the upper support housing 101.

[0034] A disc spring 124 is provided at one end of the drive gear 117, and the disc spring 124 is sleeved on the eighth connecting shaft 118; a push spring 116 is provided at the upper end of the arc block 113, the upper end of the push spring 116 is connected to the steel belt push rod 106, and the lower end is connected to the arc block 113; A second paper belt pulley 121 is provided at the other end of the drive gear 117. The second paper belt pulley 121 is fixedly connected to the eighth connecting shaft 118. A paper belt 120 is provided on the second paper belt pulley 121. A first paper belt pulley 119 is wound around one end of the paper belt 120. Several barbs 9 are provided at intervals on the paper belt 120. The first paper belt pulley 119 is sleeved on the ninth connecting shaft 123. The end of the ninth connecting shaft 123 is fixedly connected to the inner wall of the upper support housing 101. The diameters at both ends of the first paper belt pulley 119 are larger than the diameter at the middle position. The puncture needle 122 is located above the position where the diameter of the first paper belt pulley 119 is smaller. A puncture needle groove 1221 is provided on the puncture needle 122. Several square holes 1201 are spaced apart on the paper tape 120, and round holes 1202 are provided at the corners of the square holes 1201. The barb line 9 is located at the position of the square holes 1201.

[0035] Specifically, in use, the paper tape 120 is wound between the first paper tape pulley 119 and the second paper tape pulley 121, with the barbs 9 spaced apart on the paper tape 120 in a ready-to-feed state; the arc-shaped block 113 maintains its initial posture under the preload of the push spring 116, and its lower first stop 114 and second stop 115 are in close contact with the teeth of the push gear 117, restricting the rotation of the push gear 117, thereby fixing the position of the paper tape 120, so that the first barb 9 to be used is stably stopped directly below the puncture needle 122. The disc spring 124 sleeved on the eighth connecting shaft 118 is in a pre-compressed state, storing elastic potential energy for the rotation of the push gear 117; the push spring 116 is vertically stretched, providing tension for the reset of the arc-shaped block 113.

[0036] When the first moving rod 216 is activated and moves forward, it drives the steel belt push rod 106 to move synchronously. The push block 109 on the steel belt push rod 106 moves closer to the arc-shaped block 113 and applies pressure, causing the arc-shaped block 113 to rotate around the seventh connecting shaft 112. During the rotation of the arc-shaped block 113, the lower first stop block 114 rises upward and the second stop block 115 falls downward, both disengaging from the teeth of the push gear 117 and releasing the mechanical limit on the push gear 117. After the limit on the arc-shaped block 113 is released, the pre-compressed disc spring 124 releases its elastic potential energy, driving the eighth connecting shaft 118 to rotate synchronously with the push gear 117. Since the push gear 117 is fixedly connected to the second paper belt pulley 121, the second paper belt pulley 121 rotates together with the eighth connecting shaft 118, generating traction force.

[0037] When the second paper pulley 121 rotates, it pulls the paper belt 120 to move. The paper belt 120 drives the first paper pulley 119 to rotate passively around the ninth connecting shaft 123, accurately delivering the next barbed suture 9 on the paper belt 120 to the preset position below the puncture needle 122. The tooth spacing of the drive gear 117 matches the spacing of the barbed sutures 9, ensuring that each rotation of one tooth delivers exactly one barbed suture 9, achieving quantitative suture delivery. The puncture needle 122 extends downward under the drive of the steel belt 111, and the puncture needle groove 1221 at its end engages precisely with the delivered barbed suture 9, penetrating the mucosal tissue together with the puncture needle 122, completing the attachment and implantation of the suture.

[0038] After the puncture is completed, the steel strip push rod 106 retracts in the opposite direction under the tension of the return spring 108, causing the push block 109 to move away from the arc-shaped block 113. After the pressure on the push block 109 disappears, the push spring 116 releases its tension, pulling the arc-shaped block 113 to rotate in the opposite direction around the seventh connecting shaft 112, returning to its initial posture; at this time, the first stop 114 moves downward, re-engaging in the gear tooth gap of the push gear 117, and the second stop 115 returns to its original position, once again forming a bidirectional limit on the push gear 117, preventing it from rotating on its own and causing the paper strip 120 to deviate. The push gear 117 is relocked, the paper strip 120 stops moving, and the next barbed suture 9 has been delivered with the paper strip 120 to the ready-to-use position below the puncture needle 122. The suture feeding assembly completes one suture feeding cycle, preparing for the next puncture and suturing.

[0039] Specifically, the square hole 1201 ensures that the puncture needle 122 can smoothly drive the barbed wire 9 to puncture, and the barbed wire structure is adapted to facilitate quick separation during puncture; the round hole 1202 increases the static friction between the paper belt and the wheel by fitting into the surface of the first paper belt pulley 119 to prevent transmission slippage.

[0040] like Figure 8 As shown, the upper support housing 101 has an observation port 107 at its front, which is used to observe the status of the puncture needle 122 and ensure that the puncture needle 122 can be extended for suturing; the upper support housing 101 has a first T-shaped block 104 at its rear; the lower support mechanism includes a lower support housing 102, a second T-shaped block 105, and a pad 103, with the second T-shaped block 105 at one end of the lower support housing 102 and the pad 103 at its upper part; two connecting blocks 4 are provided, arranged vertically; the connecting blocks 4 have cavities inside. The upper part of the connecting block 4 is provided with a T-shaped groove 401, and the side of the connecting block 4 is provided with an arc-shaped surface 402. The first T-shaped block 104 is inserted into the T-shaped groove 401 of the upper connecting block 4, and then the upper support shell 101 is rotated so that one end of the upper support shell 101 is engaged with the arc-shaped surface 402 of the upper connecting block 4 to fix the upper support mechanism. The second T-shaped block 105 is inserted into the T-shaped groove 401 of the lower connecting block 4, and then the lower support shell 102 is rotated so that one end of the lower support shell 102 is engaged with the arc-shaped surface 402 of the lower connecting block 4 to fix the lower support mechanism.

[0041] Specifically, when installing the lower support mechanism, the second T-shaped block 105 at one end of the lower support housing 102 is aligned with the T-shaped groove 401 of the lower connecting block 4 and inserted. The lower support housing 102 is then rotated so that the end of the lower support housing 102 near the connecting block 4 is fitted and engaged with the arc-shaped surface 402 of the lower connecting block 4, thus fixing the lower support mechanism. When installing the upper support mechanism, the first T-shaped block 104 at the rear of the upper support housing 101 is aligned with the T-shaped groove 401 of the upper connecting block 4 and inserted. The upper support housing 101 is then rotated so that the end of the upper support housing 101 near the connecting block 4 is fitted and engaged with the arc-shaped surface 402 of the upper connecting block 4, thus fixing the upper support mechanism. During the surgery, the doctor can observe the position and status of the internal puncture needle 122 in real time through the observation port 107 at the front of the upper support shell 101, confirming whether the puncture needle 122 is in the puncture position and whether it is accurately aligned with the barbed suture 9. At the same time, the doctor can observe the angle and direction of the puncture needle 122 when it extends to ensure that the puncture needle 122 can accurately penetrate the target mucosal tissue and avoid operational deviations caused by limited vision. During suturing, the pad 103 on the upper part of the lower support shell 102 cooperates with the upper support mechanism to support the mucosal tissue from below, providing stable support for puncture and suturing and ensuring the smooth progress of the suturing process.

[0042] A guide block 213 is provided at one end of the first moving rod 216. The first moving rod 216 passes through the guide block 213, which guides the movement of the first moving rod 216. The upper part of the guide block 213 is fixedly connected to the inner wall of the outer shell 3. A locking groove 501 is provided on the surface of the first moving rod 216. A locking member 5 is provided inside the locking groove 501. The locking member 5 passes through the outer shell 3 and is inserted into the locking groove 501 to lock the first moving rod 216. Figure 6 As shown, the limiting mechanism 220 includes a limiting mounting plate 2201, a limiting spring 2202, and a limiting block 2203. The limiting mounting plate 2201 is symmetrically arranged on the inner wall of the outer shell 3. The limiting spring 2202 is arranged on the inner side of the limiting mounting plate 2201. One end of the limiting spring 2202 is fixedly connected to the inner wall of the outer shell 3, and the other end of the limiting spring 2202 is fixedly connected to the limiting block 2203.

[0043] Specifically, before use, the locking member 5 is inserted through the outer shell 3 into the locking groove 501 on the surface of the first moving rod 216. The locking member 5 and the locking groove 501 fix the first moving rod 216, preventing it from moving arbitrarily when not in use. When the piercing action needs to be initiated, the locking member 5 is pulled out to release the locking of the first moving rod 216. The first moving rod 216 begins to move under the tension of the first spring 217. The guide block 213 penetrating one end restricts the direction of movement of the first moving rod 216, preventing the first moving rod 216 from deviating during movement and ensuring that the first moving rod 216 can push the steel strip push rod 106 in a straight line. When the first moving rod 216 drives the first slider 214 to move towards the limiting mechanism 220, the first slider 214 presses against the limiting block 2203 of the limiting mechanism 220. The limiting block 2203 compresses the limiting spring 2202 and retracts into the limiting mounting plate 2201, allowing the first slider 214 to pass smoothly through the limiting mechanism 220. When the first slider 214 moves to the front of the limiting mechanism 220, the limiting spring 2202 resets and pushes the limiting block 2203 to extend, blocking the first slider 214 and preventing it from retracting, thus realizing the movement of the first moving rod 216. Temporary positioning; subsequently, trigger 201 is pulled again, the slider push rod 212 pushes the second slider 215 forward, the second slider 215 drives the first moving rod 216 to move in the opposite direction, and squeezes the limiting block 2203 again to retract into the mounting plate. After the first moving rod 216 moves to the designated position, the limiting block 2203 extends again to limit the second slider 215, completing the reset and charging of the first moving rod 216. Through the guidance of the guide block 213 and the limiting cooperation of the locking member 5 and the limiting mechanism 220, the stability and accuracy of the movement of the first moving rod 216 are ensured.

[0044] like Figure 3 and Figure 4 As shown, the sector gear 202 is sleeved on the first connecting shaft 203, which is movably connected to the inner wall of the outer casing 3 and to the sector gear 202; the second connecting shaft 207 is fixedly connected to the pinion 206 and the cam 230 and is movably connected to the inner wall of the outer casing 3; the third connecting shaft 208 is movably connected to the lower support rod 209 and is fixedly connected to the inner wall of the outer casing 3; a trigger spring 205 is provided on one side of the trigger 201, one end of the trigger spring 205 is fixedly connected to the trigger 201, and the other end of the trigger spring 205 is fixedly connected to the pad 204, one end of the pad 204 is fixedly connected to the inner wall of the outer casing 3.

[0045] Specifically, when trigger 201 is pulled, trigger 201 drives the upper fixed sector gear 202 to rotate around the first connecting shaft 203. Since the first connecting shaft 203 is movably connected to the inner wall of the outer casing 3, the sector gear 202 can rotate stably without deviation. During the rotation of the sector gear 202, it meshes with the upper pinion 206, driving the pinion 206 to rotate. The pinion 206 is fixedly connected to the second connecting shaft 207, thereby driving the second connecting shaft 207 to rotate synchronously. The cam 230 at one end of the second connecting shaft 207 rotates together with the second connecting shaft 207. When the cam 230 rotates, it applies pressure to one end of the lower support rod 209, causing the lower support rod 209 to rotate around the middle third connecting shaft 208. The end of the lower support rod 209 away from the cam 230 is lifted upward, pushing the lower support mechanism to move upward and cooperate with the upper support mechanism to clamp the mucosal tissue. When trigger 201 is released, trigger spring 205 on one side of trigger 201 returns to its original position, pulling trigger 201 to move in the opposite direction. Sector gear 202 rotates in the opposite direction along with trigger 201, driving pinion 206, second connecting shaft 207 and cam 230 to rotate in the opposite direction. The pressure of cam 230 on lower support rod 209 disappears, and lower support rod 209 rotates in the opposite direction around third connecting shaft 208 under its own weight and the reaction force of mucosal tissue. The lower support mechanism then falls back, releasing the clamping of mucosal tissue. Through the support of each shaft and the transmission cooperation of gears and cam 230, precise control of mucosal clamping and release is achieved.

[0046] like Figure 5 As shown, a second connecting rod 221 is provided in the middle of the first connecting rod 210. A groove is provided on the second connecting rod 221, and a fourth connecting shaft 222 is provided in the groove. The two ends of the fourth connecting shaft 222 are fixedly connected to the inner wall of the groove. A first lever 223 is sleeved on the fourth connecting shaft 222, and the end of the first lever 223 is close to the slot of the counting disk 224. Several slots are provided at intervals on the outer surface of the counting disk 224. The counting disk 224 is sleeved on the fifth connecting shaft 225. The two ends of the fifth connecting shaft 225 are fixedly connected to the inner wall of the outer shell 3. The counting disk 224 and the fifth connecting shaft 225 are movably connected. A viewing window 6 is provided on the outer shell 3, and the position of the viewing window 6 is aligned with that of the counting disk 224.

[0047] A support plate 229 is provided at one end of the counting disk 224. The support plate 229 is fixedly connected to the inner wall of the outer casing 3. The upper part of the support plate 229 is fixedly connected to the lever spring 228. The other end of the lever spring 228 is fixedly connected to the second lever 226. The middle part of the second lever 226 is sleeved on the sixth connecting shaft 227. The two ends of the sixth connecting shaft 227 are fixedly connected to the inner wall of the outer casing 3. The sixth connecting shaft 227 and the second lever 226 are movably connected. The upper end of the second lever 226 is fixedly connected to the first lever block 231. The end of the first lever block 231 is close to the second lever block 232. The upper part of the second lever block 232 is fixedly connected to the first moving rod 216. Specifically, when trigger 201 is pulled, trigger 201 moves the first connecting rod 210, and the second connecting rod 221 in the middle of the first connecting rod 210 moves together. The fourth connecting shaft 222 in the groove of the second connecting rod 221 moves the first lever 223 sleeved on it. The end of the first lever 223 slides in the slot of the counting disk 224 and moves the counting disk 224 to rotate around the fifth connecting shaft 225. The fifth connecting shaft 225 is fixed to the inner wall of the outer shell 3 to ensure that the counting disk 224 rotates stably. Each rotation of the counting disk 224 corresponds to one suturing action. The doctor can observe the rotation of the counting disk 224 through the viewing window 6 on the outer shell 3 that is aligned with the counting disk 224 to understand the number of suturing operations completed. During the rotation of the counting disk 224, its edge presses against the lower end of the second lever 226, causing the second lever 226 to rotate around the sixth connecting shaft 227. The sixth connecting shaft 227 is fixed to the inner wall of the outer casing 3, providing a fulcrum for the rotation of the second lever 226. The first lever block 231 at the upper end of the second lever 226 moves down and separates from the second lever block 232 on the first moving rod 216, releasing the restriction on the first moving rod 216. At the same time, when the second lever 226 rotates, it stretches the lever spring 228 fixed on the support plate 229. When the counting disk 224 rotates to the next slot position, the pressure on the second lever 226 disappears, the lever spring 228 resets and pulls the second lever 226 to rotate in the opposite direction. The first lever block 231 rises and comes close to the second lever block 232 again, forming a restriction on the first moving rod 216 again. Through this process, the real-time counting of the number of stitches and the synchronous switching of the restriction state of the first moving rod 216 are realized.

[0048] like Figure 1 As shown, a handle 7 is provided at the lower part of the outer shell 3, and a number of arc-shaped grooves 8 are provided at intervals at one end of the handle 7.

[0049] Specifically, during the surgery, the surgeon holds the handle 7 at the lower part of the outer shell 3, placing their fingers within the spaced-out arc-shaped grooves 8 at one end of the handle 7. These grooves conform to the shape of the fingers, increasing the contact area between the hand and the handle 7, reducing hand pressure, and preventing the handle 7 from slipping from the hand during the procedure. When the trigger 201 needs to be pulled for suturing, holding the handle 7 provides stable support for the entire instrument, preventing displacement of the puncture position due to hand movement. When adjusting the instrument angle or moving the instrument, the grip structure of the handle 7 allows the surgeon to precisely control the direction and speed of instrument movement, ensuring smooth suturing within the confined nasal cavity, thus improving operational stability and comfort during the surgery.

[0050] Example 2: A method of using a medical penetrating suture device includes the following steps: First, install the upper support mechanism and the lower support mechanism on the mounting block, and then pull the locking pin out of the locking groove 501 on the first moving rod 216; After completion, lightly pull the trigger 201 to move the trigger 201. The movement of the trigger 201 drives the sector gear to rotate. The rotation of the sector gear 202 drives the small gear 206 to rotate. The rotation of the small gear 206 drives the second connecting shaft 207 to rotate. The rotation of the second connecting shaft 207 drives the cam 230 to rotate, which in turn causes one end of the lower support rod 209 to move downward and the other end of the lower support rod 209 to move upward, thereby lifting the lower support mechanism upward and clamping the nasal mucosa. Simultaneously, the trigger 201 drives the second connecting rod 221 to move. Under the action of the fourth connecting shaft 222, the second connecting rod 221 drives the first lever 223 to move, thereby causing the counting disk 224 to rotate to achieve counting. When the counting disk 224 rotates, it causes the second lever 226 to move. The second lever 226 rotates through the sixth connecting shaft 227, thereby compressing the lever spring 228. The front end of the second lever 226 moves down, causing the first lever block 231 and the second lever block 232 to separate, thereby releasing the limit on the first connecting rod 210 and activating the first moving rod 216. The first moving rod 216, under the tension of the first spring 217, drives the first slider 214 to move, causing the first slider 214 to move toward the limiting mechanism 220, so that the limiting block 2203 of the limiting mechanism 220 is pressed into the limiting mounting plate 2201, and the limiting spring 2202 is compressed. At this time, the first slider 214 moves from the rear of the limiting mechanism 220 to the front of the limiting mechanism 220; thereby, the second slider 215 is released. Under the tension of the second spring 219, the second slider 215, the first moving rod 216, and the second lever 232 move backward until the second lever 232 moves to the front end of the second lever 226, so that the second lever 232 and the first lever 231 are pressed together again, and the first moving rod 216 is limited again. When the first moving rod 216 moves forward, it pushes the steel belt push rod 106 of the upper support mechanism, which in turn pushes the steel belt 111 to move within the steel belt slide 110, thereby causing the steel belt 111 to drive the puncture needle 122 to puncture. Figure 13 and Figure 14 As shown, during puncture, the barbed thread 9 on the paper tape 120 is hung in the puncture needle groove 1221, and then the puncture needle 122 is used to guide it to the nasal mucosa to achieve suturing. After puncture, it is quickly withdrawn. At the same time, the push block 109 on the steel belt push rod 106 moves toward the arc-shaped block 113, and the push block 109 contacts the arc-shaped block 113, causing the arc-shaped block 113 to rotate on the seventh connecting shaft 112. At this time, the first stop block 114 is raised, the second stop block 115 is lowered, the push spring 116 is compressed, releasing the limit on the push gear 117, and then the push gear 117 is rotated under the action of the disc spring 124, which in turn drives the eighth connecting shaft 118 to rotate. The eighth connecting shaft 118 drives the second paper belt pulley 121 to rotate, and the second paper belt pulley 121 drives... The paper tape 120 moves, driving the first paper tape pulley 119 to rotate, thereby sending the barbed wire 9 to the required position, so that the barbed wire 9 can be hooked in the puncture needle groove 1221 at the front end of the puncture needle 122. After puncture, the steel tape push rod 106 is pulled back to its original position by the reset spring 108; the push spring 116 pulls the arc block 113 to rotate along the seventh connecting shaft 112, the first stop block 114 moves downward, and the push gear 117 is limited again to ensure that the push gear 117 rotates a distance of one tooth. The second stop block 115 moves upward to reset, thereby facilitating the next wire feeding.

[0051] The counting, puncture of the puncture needle 122, and upward movement of the lower support mechanism are all completed simultaneously, thereby achieving clamping and puncture while counting, ensuring the stability of the puncture of the barb line 9, and the accuracy of the counting. Next, continue to pull the trigger 201. The trigger 201 drives the push rod connecting block 211 to move. The push rod connecting block 211 drives the slider push rod 212 to move towards the second slider 215. This pushes the second slider 215 forward until it reaches the front of the limiting mechanism 220 and stops moving. The limiting mechanism 220 limits the second slider 215 again, thereby compressing the first spring 217 and charging it, which facilitates the next puncture and suturing.

[0052] Specifically, during nasal septum mucosal suturing surgery, the first step is to assemble and prepare the instruments, with both the upper and lower support mechanisms being disposable consumables. The first T-shaped block 104 of the upper support mechanism is inserted into the T-groove 401 of the upper connecting block 4 at one end of the outer shell 3. The upper support outer shell 101 is rotated to engage with the arc-shaped surface 402 of the upper connecting block 4. Then, the second T-shaped block 105 of the lower support mechanism is inserted into the T-groove 401 of the lower connecting block 4. The lower support outer shell 102 is rotated to engage with the arc-shaped surface 402 of the lower connecting block 4, completing the installation of the upper and lower support mechanisms. Subsequently, the locking piece 5, which penetrates the outer shell 3 and is inserted into the locking groove 501 of the first moving rod 216, is removed, releasing the fixation on the first moving rod 216 and preparing for subsequent operations.

[0053] After preparation, the doctor holds the handle 7 at the bottom of the outer casing 3, placing their fingers in the arc-shaped groove 8 of the handle 7 for a stable grip on the instrument. The upper and lower support mechanisms are aligned with the nasal septum mucosa to be sutured. The trigger 201 is lightly pulled, causing the upper fixed sector gear 202 to rotate around the first connecting shaft 203. The sector gear 202 meshes with the upper pinion 206, driving the pinion 206 to rotate the second connecting shaft 207. The cam 230 on the second connecting shaft 207 rotates accordingly, applying pressure to one end of the lower support rod 209, causing it to rotate around the middle third connecting shaft 208. The other end of the lower support rod 209 lifts upward, pushing the lower support mechanism upward to cooperate with the upper support mechanism in clamping the nasal mucosa, achieving stable fixation of the mucosa.

[0054] Simultaneously, the movement of trigger 201 also drives the first connecting rod 210 to move synchronously. The second connecting rod 221 in the middle of the first connecting rod 210 moves accordingly. The fourth connecting shaft 222 in the groove of the second connecting rod 221 drives the first lever 223 sleeved on it to move. The end of the first lever 223 slides in the slot of the counting disk 224 and moves the counting disk 224 to rotate around the fifth connecting shaft 225. The doctor can observe the rotation of the counting disk 224 through the viewing window 6 on the outer shell 3 to realize real-time counting of the number of sutures. When the counting disk 224 rotates, it presses the lower end of the second lever 226, causing the second lever 226 to rotate around the sixth connecting shaft 227. The lever spring 228 is compressed, and the first lever block 231 at the upper end of the second lever 226 moves down and separates from the second lever block 232 on the first moving rod 216, releasing the restriction on the first moving rod 216 and activating the first moving rod 216.

[0055] The first moving rod 216, under the tension of the first spring 217, drives the first slider 214 to move towards the limiting mechanism 220. The first slider 214 presses against the limiting block 2203 of the limiting mechanism 220, causing the limiting block 2203 to compress the limiting spring 2202 and retract into the limiting mounting plate 2201. The first slider 214 then smoothly moves from the rear to the front of the limiting mechanism 220. At this time, the second slider 215 is released and, under the tension of the second spring 219, drives the first moving rod 216 and the second lever 232 to move backward together until the second lever 232 moves to the front end of the second lever 226 and re-engages with the first lever 231, thus limiting the first moving rod 216 again.

[0056] During the forward movement of the first moving rod 216, its end pushes the steel belt push rod 106 of the upper support mechanism. The steel belt push rod 106 drives the steel belt 111 to move within the steel belt slide 110. The puncture needle 122 connected to the other end of the steel belt 111 extends out of the upper support housing 101 along with the steel belt 111. When the puncture needle 122 moves downward, the puncture needle groove 1221 at its bottom catches the barbed thread 9 delivered to the position on the paper tape 120, and together with the puncture needle 122, it penetrates the clamped nasal mucosa tissue to achieve a through suture. Subsequently, the puncture needle 122 is quickly withdrawn into the upper support housing 101 under the action of the steel belt 111.

[0057] At the same time, the push block 109 on the steel belt push rod 106 moves toward the arc-shaped block 113, and the push block 109 contacts the arc-shaped block 113, causing the arc-shaped block 113 to rotate on the seventh connecting shaft 112. At this time, the first stop block 114 is raised, the second stop block 115 is lowered, the push spring 116 is compressed, releasing the limit on the push gear 117, and then the push gear 117 is rotated under the action of the disc spring 124, which in turn drives the eighth connecting shaft 118 to rotate. The eighth connecting shaft 118 drives the second paper belt pulley 121 to rotate, and the second paper belt pulley 121 drives... The paper tape 120 moves, driving the first paper tape pulley 119 to rotate, thereby sending the barbed wire 9 to the required position, so that the barbed wire 9 can be hooked in the puncture needle groove 1221 at the front end of the puncture needle 122. After puncture, the steel tape push rod 106 is pulled back to its original position by the reset spring 108; the push spring 116 pulls the arc block 113 to rotate along the seventh connecting shaft 112, the first stop block 114 moves downward, and the push gear 117 is limited again to ensure that the push gear 117 rotates a distance of one tooth. The second stop block 115 moves upward to reset, thereby facilitating the next wire feeding.

[0058] After a single suture is completed, continue to hold the trigger 201. The trigger 201 moves the push rod connecting block 211, which in turn moves the slider pushing rods 212 at both ends toward the second slider 215. The slider pushing rods 212 push the second slider 215 forward, and the second slider 215 moves the first moving rod 216 synchronously, compressing the first spring 217. When the second slider 215 moves to the front of the limiting mechanism 220, the limiting block 2203 of the limiting mechanism 220 pops out under the action of the limiting spring 2202, blocking the second slider 215 and completing the limitation of the second slider 215. At this time, the first spring 217 is in a compressed state and is charged. The instrument returns to the ready-to-puncture state, making it convenient for the doctor to perform the next mucosal puncture and suture operation. Repeating the above steps can complete the penetrating suture of the entire nasal septum mucosa.

Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.

10. A method of using a medical penetrating suture device as described in any one of claims 1-9, characterized in that, Includes the following steps: First, install the upper support mechanism and the lower support mechanism on the mounting block, and then pull the locking pin out of the locking groove on the first moving rod; Once completed, gently pull the trigger to move it. The movement of the trigger causes the sector gear to rotate, which in turn causes the pinion to rotate. The pinion then causes the second connecting shaft to rotate, which in turn causes the cam to rotate. This causes one end of the lower support rod to move downward and the other end to move upward, thereby lifting the lower support mechanism upward and clamping the nasal mucosa. At the same time, the trigger drives the second connecting rod to move, and the second connecting rod drives the first lever to move under the action of the fourth connecting shaft, thereby causing the counting disk to rotate to realize counting; when the counting disk rotates, it causes the second lever to move, and the second lever rotates through the sixth connecting shaft, thereby compressing the lever spring. The front end of the second lever moves down to separate the first and second lever blocks, thereby releasing the limit on the first connecting rod and activating the first moving rod. The first moving rod, under the tension of the first spring, drives the first slider to move, causing the first slider to move toward the limiting mechanism. This causes the limiting block of the limiting mechanism to be pressed into the limiting mounting plate, and the limiting spring to be compressed. At this time, the first slider moves from the rear of the limiting mechanism to the front of the limiting mechanism. This releases the second slider, which, under the tension of the second spring, drives the second slider, the first moving rod, and the second lever to move backward until the second lever moves to the front end of the second lever, so that the second lever and the first lever are tightly pressed together again, and the first moving rod is limited again. When the first moving rod moves forward, it pushes the steel belt push rod of the upper support mechanism, which in turn pushes the steel belt to move in the steel belt slide, thereby causing the steel belt to drive the puncture needle to puncture. During puncture, the barbed thread on the paper tape is hung in the puncture needle groove, and then the puncture needle is brought into the nasal mucosa to achieve suturing. After puncture, it is quickly withdrawn. Meanwhile, the push block on the steel strip push rod moves towards the arc-shaped block, and the push block contacts the arc-shaped block, causing the arc-shaped block to rotate on the seventh connecting shaft. At this time, the first stop block is raised, the second stop block is lowered, the push spring is compressed, releasing the limit on the push gear, and then the push gear rotates under the action of the disc spring, which in turn drives the eighth connecting shaft to rotate. The eighth connecting shaft drives the second paper belt pulley to rotate, the second paper belt pulley drives the paper belt to move, and the paper belt drives the first paper belt pulley to rotate, thus feeding the barbed wire to the required position, so that the barbed wire can be hooked in the puncture needle groove at the front end of the puncture needle. After puncture, the steel strip push rod is pulled back to its original position by the reset spring; the push spring pulls the arc-shaped block to rotate along the seventh connecting shaft, the first stop block moves downward, and the push gear is limited again to ensure that the push gear rotates a distance of one tooth. The second stop block moves upward to reset, thus facilitating the next wire feeding. The counting, puncture needle insertion, and upward movement of the lower support mechanism are all completed simultaneously, thereby achieving clamping and puncture while counting, ensuring the stability of the barbed puncture and the accuracy of the counting; Then, continue to pull the trigger. The trigger moves the push rod connecting block, which in turn moves the push rod connecting block, which in turn moves the slider push rod toward the second slider, thus pushing the second slider forward until it stops moving in front of the limiting mechanism. The limiting mechanism then limits the second slider again, thereby compressing the first spring and charging it, which facilitates the next puncture and suturing.
