Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a wound suture device. Background Technology

[0002] Wound suturing is a fundamental surgical procedure used to close incisions, reduce bleeding, and promote tissue healing. Traditional suturing methods rely on the surgeon's manual skills. With advancements in technology, wound suture devices are increasingly used for wound suturing, mechanizing the wound in a manner similar to staplers, thus reducing the uncertainty of human intervention. However, traditional wound suture devices still require the surgeon to use their other hand to grasp the skin and flesh on both sides of the wound, bringing them together before suturing with the device. This not only increases the complexity of the surgery but can also lead to poor suturing results due to hand tremors or improper operation. Furthermore, the surgeon needs to perform both grasping and suturing simultaneously during the process, prolonging the entire procedure, especially when multiple wounds require suturing, significantly reducing efficiency. Additionally, the force and position of the grasping action can affect the quality of the suturing, leading to uneven tension on the staples and impacting healing outcomes.

[0003] Therefore, there is an urgent need for a wound closure device to solve the problems existing in the current technology. Utility Model Content

[0004] In view of this, the present invention proposes a wound suture device, which aims to solve the problem that existing wound suture devices do not have a tightening function.

[0005] This utility model provides a wound closure device, comprising:

[0006] The housing has a first hole at the lower rear end and a second hole at the lower front end, and a first rotating shaft is provided in the middle of the inner side of the housing;

[0007] A firing handle, which passes through the first hole and is disposed inside the housing, and is rotatably connected to the first rotating shaft;

[0012] Furthermore, the clamping part includes a clamping block and a clamping rod, one end of the clamping rod is fixedly connected to the firing handle, and the other end of the clamping rod is fixedly connected to the clamping block, the clamping block being located above the first fastening plate.

[0013] Furthermore, the propulsion unit includes an extrusion section and a propulsion section. The extrusion section is disposed above the second hole, and the propulsion section is disposed below the extrusion section. The front end of the propulsion section is located between the second hole and the extrusion section.

[0014] Furthermore, the extrusion section includes a first extrusion block, a second extrusion block, and a first torsion spring. The first extrusion block is disposed below the front end of the firing handle, and the first extrusion block is slidably connected to the second extrusion block. The second extrusion block is provided with a torsion spring inside.

[0015] Furthermore, the propulsion unit includes a propulsion base plate, a first propulsion plate, a second propulsion plate, and a second torsion spring.

[0017] Furthermore, limit holes are provided through the inner walls of the housing on both sides of the propulsion base plate, and limit screws are threadedly connected to the limit holes.

[0018] Furthermore, the outer surfaces of the propulsion unit and the clamping unit are coated with silver ions.

[0019] Furthermore, an arrow is provided on the outer surface of the housing, and the arrow is located above the second hole.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting clamping units on both sides of the advancement unit, when the doctor operates, he only needs to press the firing handle, which in turn drives the clamping unit to tighten the skin and flesh on both sides of the wound.

[0029] See Figure 1-3 As shown, this embodiment provides a wound suture device, including: a housing 1, a first hole 101 is provided at the lower rear end of the housing 1, a second hole 102 is provided at the lower front end of the housing 1, and a first rotating shaft 201 is provided in the middle of the inner side of the housing 1;

[0030] A firing handle 2 is disposed inside the housing 1 through the hole, and the firing handle 2 is rotatably connected to the first rotating shaft 201;

[0031] A propulsion unit 3 is disposed at the front part inside the housing 1, and the propulsion unit 3 is connected to the firing handle 2;

[0032] The clamping unit 4 includes a fastening part and a clamping part. There are two fastening parts. The fastening parts are located below the propulsion unit 3. A sliding groove is provided on the inner side of the fastening part. The bottom wall of the sliding groove is inclined. A sliding rod is provided in the sliding groove. The other end of the sliding rod is fixedly connected to the firing handle 2. The clamping part is located on the outside of the housing 1 and on one side of the firing handle 2.

[0033] The suture pin is located inside the propulsion unit 3.

[0034] Specifically, the housing 1 has a first hole 101 and a second hole 102. The first hole 101 allows the firing handle 2 to move, and the second hole 102 is used to contact the wound while suturing it with sutures. The propulsion unit 3 is located inside the housing 1, with one end of the propulsion unit 3 located inside the second hole 102. The clamping unit 4 is located below the propulsion unit 3. When the doctor begins suturing the wound, he only needs to align the second hole 102 with the wound and press the firing handle 2. The firing handle 2 then drives the clamping unit 4, and the clamping part directly contacts the skin. The inner side of the clamping part is provided with a groove, and the bottom wall of the groove is designed to be inclined. When the firing handle 2 is pressed, the firing handle 2 moves... The sliding rod moves backward, and during the movement, due to the inclined design of the slide groove, the bottom wall of the slide groove becomes higher as it moves backward, thereby enabling the front end of the fastening part to tighten inward. The fastening parts on both sides of the second hole 102 can tighten the skin on both sides of the wound. The fastening part is located on one side of the firing handle 2. When the fastening part tightens the skin on both sides of the wound, the fastening part applies a downward force to the fastening part under the action of the firing handle 2. Since the downward force applied by the fastening part is located on the side of the fastening part, the position of the fastening part in contact with the skin can be lifted upward, which can further tighten the skin. At the same time, the lifted skin can also facilitate the entry of the suture staples without damaging the deep tissue under the skin.

[0035] Understandably, by simply pressing the firing handle 2, the doctor can activate the tightening unit 4 and the advancing unit 3 to quickly tighten the skin on both sides of the wound and insert the suture staples for suturing. This simplifies the traditional manual operation process, reduces the doctor's operational difficulty and time, and improves suturing efficiency. Especially in emergency situations, it can reduce surgical time and patient waiting time. The tightening unit 4, through the cooperation of the fastening and securing parts, ensures a tight fit between the skin on both sides of the wound, which helps in the accurate positioning of the suture staples. This not only improves the stability of the suture but also effectively avoids loose sutures, dehiscence, or postoperative complications caused by skin laxity or misalignment. The downward force applied by the tightening unit 4, especially the tightening part, makes the skin adhere more tightly, avoiding wound enlargement or damage to deeper tissues due to excessive traction. The smooth entry of the suture staples into the wound without damaging underlying tissues further reduces trauma during the operation, improving surgical safety and postoperative recovery. The tightening unit 4, in conjunction with the advancing unit 3, ensures that the suture staples accurately enter the wound at the appropriate time, reducing human error during the surgeon's operation. This is especially important in high-pressure clinical environments, lowering the likelihood of surgical accidents. It not only ensures ease of operation for the surgeon but also effectively avoids further wound damage and infection risks. Furthermore, it reduces patient pain during surgery. The downward force of the tightening unit prevents excessive traction when the fastening part is close to the skin, thus alleviating patient pain. Simultaneously, the automated suturing function reduces the repetitive manipulation and traction that may occur with traditional manual suturing, reducing patient discomfort and postoperative recovery time. The cooperation between the tightening unit 4 and the advancing unit 3 eliminates the need for excessive manual adjustment of the wound. By precisely controlling wound tension and suture depth, it improves the accuracy of wound closure, leading to smoother postoperative recovery and reducing the occurrence of subsequent infections and complications.

[0036] In some embodiments of this application, the fastening part includes a fastening plate 4101 and a first fastening piece 4102. The fastening plate 4101 is provided with the first fastening piece 4102 in the middle, and the first fastening piece 4102 is provided with a groove in the middle of one side.

[0037] Specifically, half of the fastening plate 4101 is located inside the housing 1 and the other half is located outside the housing 1. The part located inside the housing 1 is provided with a sliding groove and a sliding rod, and the part located outside the housing 1 is provided with a first fastening piece 4102. The first fastening piece 4102 is used to contact the fastening part when it swings downward. The first fastening piece 4102 can limit the fastening part and apply a downward force to the first fastening plate 4101 at the same time, so that the first fastening plate 4101 is in the form of the outside downward and the inside upward. In this way, the front end of the first fastening plate 4101 can tighten the skin on both sides of the wound and pull the skin upward, which facilitates the entry of the suture staple and improves the tightness of the skin on both sides of the wound.

[0038] Understandably, the tightening of the skin on both sides of the wound is ensured by the fastening plate 4101 and the first fastening piece 4102, combined with the downward force of the tightening part. Specifically, when the tightening part swings downward, the contact between the first fastening piece 4102 and the tightening part effectively limits the swing amplitude of the tightening part, while simultaneously transmitting the downward force to the fastening plate 4101. The fastening plate 4101 not only tightens the skin on both sides of the wound, but also, through angle adjustment, maintains appropriate tension and alignment of the skin during suturing, thereby improving the accuracy of suturing. It can precisely tighten the skin without causing excessive stretching, avoiding the unstable suturing caused by skin laxity in traditional suturing methods, ensuring close adhesion of the skin on both sides of the wound, and effectively improving the suturing effect. When the fastening plate 4101 pulls up the skin, the skin on both sides will adhere more tightly, avoiding gaps or irregular sutures on the wound surface due to laxity, thereby reducing the risk of infection and improving the quality of postoperative healing. Meanwhile, doctors no longer need to manually adjust wound tension. The automatic tightening system simplifies the procedure, reduces complexity, and improves surgical efficiency. The fastening plate 4101, through the coordinated action of its groove and rod, applies precise downward force under the action of the tightening unit. This causes the outer side of the first fastening plate 4101 to face downwards, while the inner side is slightly raised, promoting tighter skin adhesion, reducing the possibility of unstable sutures, and improving suture results. This precise control ensures a tighter connection between the skin on both sides of the wound, avoiding postoperative complications caused by uneven tension. It also reduces scar hyperplasia caused by improper wound tension, preventing excessive scar tissue formation. Furthermore, the tight connection reduces the risk of infection and improves the quality of postoperative recovery. Simultaneously, because the force of the tightening unit is evenly distributed on both sides of the wound, it avoids excessive stretching or uneven force application, thereby reducing deep tissue and vascular damage caused by excessive traction. This design helps reduce the risk of postoperative infection, hematoma, and nerve damage.

[0039] In some embodiments of this application, the clamping part includes a clamping block 4201 and a clamping rod 4202. One end of the clamping rod 4202 is fixedly connected to the firing handle 2, and the other end of the clamping rod 4202 is fixedly connected to the clamping block 4201. The clamping block 4201 is located above the first fastening plate 4102.

[0040] Specifically, the clamping rod is fixedly connected to the firing handle 2. When the firing handle 2 is displaced, it causes the clamping rod 4202 to be displaced, which in turn causes the clamping block 4201 fixedly connected to the front end of the clamping rod 4202 to be displaced towards the first fastening plate 4102.

[0041] Understandably, the structure of the clamping rod 4202 and clamping block 4201 further enhances the stability and precision of the clamping mechanism. Especially during surgery, the clamping rod 4202 pushes the clamping block 4201 towards the first fastening plate 4102, thereby achieving precise clamping and stretching of the skin on both sides of the wound. The clamping mechanism, through the linkage of the clamping rod 4202 and clamping block 4201, enables force transmission. When the firing handle 2 is displaced, the clamping rod 4202 drives the clamping block 4201 to move towards the first fastening plate 4102. The clamping block 4201 applies uniform pressure during contact with the first fastening plate 4102, ensuring a tight fit between the skin on both sides of the wound. Compared to traditional manual clamping methods, this design controls the clamping force through mechanical transmission, avoiding instability factors inherent in manual operation. This structural optimization allows for a tighter fit between the two sides of the wound, providing a more stable foundation for subsequent suturing and reducing the risk of poor wound healing due to skin laxity or asymmetrical suturing. Traditional surgical suturing typically requires doctors to manually adjust the tension on both sides of the wound. This is not only time-consuming but also easily limited by the surgeon's experience and skill level, leading to unnecessary errors and surgical delays. However, with the automated adjustment of the tensioning lever 4202 and tensioning block 4201, doctors can easily control the magnitude and direction of the tensioning force simply by pressing the firing handle 2. This reduces the tedious steps doctors take during the procedure, allowing them to focus more on the suturing itself and improving the efficiency and precision of the surgery.

[0042] In some embodiments of this application, the propulsion unit 3 includes a squeezing part 310 and a propulsion part 320. The squeezing part 310 is disposed above the second hole 102, and the propulsion part 320 is disposed below the squeezing part 310. The front end of the propulsion part 320 is located between the second hole 102 and the squeezing part 310.

[0043] Specifically, the extrusion part 310 is disposed above the second hole 102, and the upper end of the extrusion part 310 is attached to the front end of the firing handle 2, so that the firing handle 2 can apply downward extrusion force to the extrusion part 310. The propulsion part 320 is located inside the housing 1 and is located on one side inside the second hole 102. The front end of the propulsion part 320 is directly facing the second hole 102. When the extrusion part 310 extrudes downward, it is convenient for the sewing staple to sew downward.

[0044] Understandably, due to the structural cooperation of the compression section 310 and the propulsion section 320, the two sides of the wound can be better aligned, promoting skin healing and reducing scar hyperplasia caused by uneven tension or asymmetrical suturing at the wound edges. Tight wound closure helps reduce the risk of postoperative infection, promotes blood circulation during the healing process, and further accelerates the patient's recovery time. Precise control of the suture staple position avoids potential damage during suturing, ensuring smooth and aesthetically pleasing wound healing. Automated suturing not only improves the efficiency of the surgeon but also reduces the complexity of equipment operation. Efficient wound suturing and stable closure reduce postoperative complications and adverse reactions. Postoperative complications such as infection, bleeding, and scar hyperplasia often affect the patient's recovery progress and quality of life; this embodiment reduces the occurrence of these problems. Stable and tight wound closure provides optimal conditions for tissue repair, helps reduce the occurrence of postoperative secondary problems, and helps patients return to normal life and work in a shorter time.

[0045] In some embodiments of this application, the compression part 310 includes a first compression block 3101, a second compression block 3102 and a first torsion spring 3103. The first compression block 3101 is disposed below the front end of the firing handle 2. The first compression block 3101 is slidably connected to the second compression block 3102. The second compression block 3102 is provided with a torsion spring.

[0046] Specifically, the first compression block 3101 fits against the front end of the firing handle 2, and the second compression block 3102 has a through hole. The lower part of the first compression block 3101 is inserted into the second compression block 3102. At the same time, the second compression block 3102 is provided with a first torsion spring 3103. When the firing handle 2 is displaced, its front end touches the first compression block 3101 and presses it downward, thereby driving the second compression block 3102 to move downward. The second compression block 3102 contacts the suture staple, and the suture staple sutures the wound.

[0047] Understandably, traditional manual suturing often requires doctors to adjust and precisely control the skin tension on both sides of the wound multiple times at different steps. This is not only time-consuming but also prone to errors due to fatigue or inaccuracies. However, by positioning the compression part 310 above the second hole 102 and cooperating with the advance part 320, the firing handle 2 can apply downward pressure, thereby pushing the suture staple towards the wound. The entire suturing process is smoother and more automated, reducing the difficulty of operation for doctors and allowing them to focus more on other aspects of wound management. This further improves the efficiency and accuracy of the surgery, especially in emergency and high-pressure situations, shortening operation time, reducing patient waiting time, and lowering the risks during surgery. The cooperation between the compression part 310 and the advance part 320 ensures accurate positioning of the suture staple and uniform transmission of the pushing force. The compression part 310, in cooperation with the firing handle 2, can apply a uniform and stable downward pressure, ensuring that the advance part 320 can push the suture staple into the wound and complete the suturing. The advancing section 320 ensures that the suture staples do not shift when entering the wound, reducing the risk of wound edge dehiscence or unstable suturing due to inaccurate staple placement or uneven force. Thanks to the control of the squeezing section 310, the entire suturing process can be completed smoothly while ensuring tight contact between the skin on both sides of the wound. This avoids the problems of skin asymmetry or incomplete wound closure that can occur due to improper manual operation in traditional surgical methods, thus improving wound healing. In traditional manual suturing, especially for larger or deeper wounds, surgeons need to carefully control the tension of each stitch and the insertion depth of the suture staples. Slight carelessness can lead to deep tissue damage, bleeding, or uneven suturing. However, the cooperation between the squeezing section 310 and the advancing section 320 ensures that the applied force is within a reasonable range each time, avoiding overstretching or over-suturing. More importantly, the control of the advancing section 320 prevents the suture staples from entering deep tissue, thereby reducing the risk of accidents during surgery. Traditional surgical suturing, due to the need for repeated tightening and adjustment of the wound, often causes significant pain and discomfort for patients, especially when delicate operations and suturing large wounds are required, potentially leaving patients in an uncomfortable state for extended periods. This embodiment, through automated squeezing and pushing functions, quickly tightens the wound while avoiding excessive pulling caused by manual adjustments, thus reducing patient discomfort during surgery. Because the force distribution of the tightening part is even, the stretching of the skin does not cause excessive discomfort, allowing patients to better tolerate the procedure and reducing postoperative pain.

[0048] In some embodiments of this application, the propulsion unit 320 includes a propulsion base plate 3201, a first propulsion plate 3202, a second propulsion plate 3203, and a second torsion spring 3204. The propulsion base plate 3201 is slidably connected to the lower inner surface of the housing 1. One end of the propulsion base plate 3201 is fixedly connected to the first propulsion plate 3202. The second propulsion plate 3203 is rotatably connected to the propulsion base plate 3201. The second torsion spring 3204 is provided between the first propulsion plate 3202 and the second propulsion plate 3203.

[0049] In some embodiments of this application, the propulsion unit 320 further includes a limiting plate 3205 and a nail storage plate 3206. The limiting plate 3205 is fixedly connected to both sides of the second extrusion block 3102, and the nail storage plate 3206 is disposed in the middle of the second extrusion block 3102.

[0050] Specifically, a first push plate 3202 and a second push plate 3203 are provided on the push base plate 3201. The first push plate 3202 is fixedly connected to the push base plate 3201. At the same time, a guide rod is fixedly connected to the other side of the first push plate 3202, and the other end of the guide rod is fixedly connected to the firing handle 2. A second torsion spring 3204 is disposed in the second push plate 3203 and the first push plate 3202. A limit plate 3205 is provided on the second push plate 3203 facing the second hole 102. The staple storage plate 3206 is located at the center of the second push plate 3203, and the limiting plate 3205 is located on both sides of the second push plate 3203. The second push plate 3203 is rotatably connected to the push base plate 3201. When the firing handle 2 is displaced, the firing handle 2 drives the first push plate 3202 to move backward, which in turn drives the second push plate 3203 to rotate, thereby causing the suture staples on the staple storage plate 3206 to move forward, so that the compression part 310 can suture the wound.

[0051] Understandably, the advancement and placement of suture staples are achieved by controlling the advancing part 320, especially the cooperation of the first advancing plate 3202 and the second advancing plate 3203. In traditional manual suturing, doctors need to manually operate each step, including controlling the advancing force and placement depth of the suture staples. This not only increases the complexity of the operation but also easily leads to problems such as uneven suturing or asymmetrical depth due to improper operation. This design, with the assistance of the limiting plate 3205 and the staple storage plate 3206, can control the sequence and advancing depth of the suture staples, making the placement of the suture staples more stable and reliable. In particular, the staple storage plate 3206 can supply suture staples during advancement and ensure that the entry sequence and position of each suture staple are correct, which can improve the accuracy of the suturing process and avoid deviations and errors that may occur in traditional surgery, thereby ensuring stable wound closure and better healing results. The limiting plate 3205 is fixedly connected to both sides of the second compression block 3102 to ensure that the suture staples do not deviate during advancement, thus limiting the movement trajectory of the suture staples. This avoids excessive or uneven force application during the advancement process, further improving the system's safety. By pushing the firing handle 2, the first advancement plate 3202 moves backward, which in turn drives the second advancement plate 3203 to rotate, pushing the suture staples on the staple storage plate 3206 forward, thus completing the advancement and force application of the suture staples. The entire process is controlled by the firing handle 2, and the precise coordination between the various components allows the suturing operation to be completed in a short time, saving doctors' time and improving operational accuracy.

[0052] In some embodiments of this application, the inner walls of the housing 1 on both sides of the propulsion base plate 3201 are provided with limiting holes 103, and the limiting holes 103 are threadedly connected to limiting screws.

[0053] Specifically, one end of the push base plate 3201 is rotatably connected to the housing 1 via a limiting screw, so that when the suture nails are used up, the other end of the push base plate 3201 is separated from the housing 1 by loosening the limiting screw, thereby allowing the push base plate 3201 to rotate out, which facilitates the installation of the suture nails.

[0054] Understandably, by providing a limiting hole 103 between the push base plate 3201 and the housing 1, and adjusting the limiting screw, the push base plate 3201 can easily separate from the housing 1 after the sutures are used up. This allows doctors to quickly replace the sutures, reducing the complexity of suture replacement and ensuring that the surgery can resume normal operation in the shortest possible time. Especially in emergency situations, this simple replacement mechanism can reduce surgical interruption time and ensure the smooth progress of the surgery. Medical devices inevitably experience wear and tear over long-term use, especially in equipment involving frequent suture replacement. The combination of the limiting screw and the limiting hole 103 allows doctors to quickly disassemble and reinstall sutures after they are used up, without the need for cumbersome disassembly or extensive parts replacement. This improves the ease of operation, reduces maintenance costs and time, and avoids maintenance delays caused by complex disassembly.

[0055] In some embodiments of this application, the outer surfaces of the propulsion unit 3 and the clamping unit 4 are provided with a silver ion coating.

[0056] Understandably, the antibacterial properties of the silver ion coating are one of its most prominent advantages. Silver ions themselves have a strong antibacterial effect, inhibiting bacterial growth and reproduction. The silver ion coating can release silver ions to disrupt bacterial cell membranes and interfere with bacterial metabolic processes, thereby achieving an antibacterial effect. This is crucial for the application of medical devices, especially in surgeries such as wound suturing that require direct contact with human skin and wounds, preventing complications caused by bacterial infection. By coating the outer surfaces of the propulsion unit 3 and clamping unit 4 with a silver ion coating, the growth and spread of pathogens during surgery can be reduced, decreasing the risk of nosocomial infections caused by device contamination. Modern medical devices not only need to address the challenge of bacterial infection but also the risk of transmission of various viruses. Silver ions have been proven to effectively inhibit the spread of many viruses, including influenza viruses and herpes viruses. For medical devices involving contact with blood or bodily fluids, the risk of viral transmission always exists. The silver ion coating can reduce the adhesion and spread of viruses, further enhancing the hygiene and safety of the device during use, ensuring that the device maintains a low risk of viral transmission in every surgical procedure, providing a safer treatment environment for patients, and avoiding cross-infection problems caused by device contamination.

[0057] In some embodiments of this application, an arrow 6 is provided on the outer surface of the housing 1, and the arrow 6 is located above the second hole 102.
