Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of surgical suturing, in particular to a magnetic-assisted minimally invasive suturing instrument for vascular surgery. Background Art
[0002] In the field of vascular surgery, minimally invasive suturing technology has become an important clinical treatment method due to its advantages such as small incision and rapid recovery. With the continuous development of medical technology, patients' requirements for surgical safety, precision, and postoperative recovery are increasing. This has prompted the design of surgical instruments to pay more attention to the combination of functionality and ease of use to meet complex and changing clinical needs.
[0003] After searching, the announcement number is: CN115414083A. The present invention provides a suture fixation auxiliary device for difficult-to-surgical operations, including a sleeve, a hard core, a suture fixation base, and a locking ring. The sleeve includes a tube body, and the outer wall of the tube body is formed with inverted teeth. The bottom end of the hard core is formed with a tip for puncturing human tissue. The suture fixation base is sleeved on the bottom of the tube body to limit the movement of the tube body outside the human body. The locking ring is sleeved on the top of the tube body, and a suture attachment point for suturing is provided on the locking ring. At the same time, the locking ring is used to limit the movement of the tube body into the human body. The present invention can effectively reduce the difficulty of suturing in narrow and awkward operating areas during surgery, provide stable and regular suture attachment points for suturing, thereby making surgical sutures more firm and reliable, significantly reducing the difficulty of surgical operations, and improving surgical safety.
[0004] At present, traditional minimally invasive suturing instruments for vascular surgery have many limitations in actual use. On the one hand, existing fixation devices mostly use bandage wrapping or clamping to fix the patient's limbs, which is not only cumbersome to operate, but also unstable in fixation effect. During the operation, slight movement of the patient's limbs may cause the wound position to shift, affecting the accuracy of suturing; on the other hand, hemostasis and wound disinfection are relatively independent and lack collaborative design. Medical staff need to frequently switch operating steps, which prolongs the operation time and increases the risk of wound infection. In addition, the compression and hemostasis effect of the instrument on the blood vessels is limited, and it is difficult to effectively control bleeding in a short period of time, which in turn affects the operation process and patient prognosis. Summary of the Invention
[0005] In response to the shortcomings of the existing technology, the present invention provides a magnetic-assisted minimally invasive suturing instrument for vascular surgery, which solves the problems of unstable fixation effect and the need for medical staff to frequently switch operating steps, thereby prolonging the operation time.
[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a magnetic-assisted minimally invasive suturing instrument for vascular surgery, comprising a support platform, the top of the support platform is fixedly connected to a fixed splint, the top of the fixed splint is rotatably connected to a rotating splint, the right sides of the rotating splint and the fixed splint are connected by a locking assembly, the top side of the fixed splint is provided with airbag 2 and airbag 1, the bottom end of the support platform is connected to a base plate by bolts, the top of the base plate is fixedly connected to a storage box, the rear end of the storage box is provided with a spray assembly, a plurality of air pumps are fixedly connected to the middle of the top of the base plate, and the output ends of the air pumps are fixedly connected to connecting pipes.
[0007] Preferably, the locking assembly includes a clamping strip fixedly connected to the right outer wall of the fixed splint and a fixed block fixedly connected to the right outer wall of the rotating splint. The middle end of the fixed block is connected to a clamping plate through a torsion spring. The outer wall of the clamping strip is fixedly connected to a plurality of locking teeth, and the left side of the bottom end of the clamping plate can be engaged with the locking teeth.
[0008] Preferably, the spray assembly includes an infusion pump body located at the rear end of the storage box, the input end of the infusion pump body is connected to the storage box, the output end of the infusion pump body is fixedly connected to a hose, and the end of the hose away from the infusion pump body is fixedly connected to a nozzle.
[0009] Preferably, a surgical opening is provided at the top of the rotating splint, a collecting trough is provided on the left side of the surgical opening, and a scale line is provided on the right side of the surgical opening.
[0010] Preferably, there are two air pumps, one of which is connected to airbag 2 via a connecting tube, and the other is connected to airbag 1 via a connecting tube.
[0011] Preferably, the left outer wall of the fixed splint is fixedly connected to a placement platform, and the bottom of the placement platform is fixedly connected to the left outer wall of the support platform via a support rod.
[0012] Preferably, the middle end of the right side outer wall of the fixed splint is fixedly connected to a limiting block, and a slot is provided on the right side of the limiting block.
[0013] Preferably, the bottom end of the base plate is fixedly connected to a support foot, and the bottom end of the support foot is fixedly connected to a magnet.
[0014] Preferably, the number of the airbags is two, and the airbags are located at the front and rear ends of the inner top of the fixed splint; the number of the airbag is one, and the airbag is located at the middle end of the inner top of the fixed splint.
[0015] Preferably, a filling pad is fixedly connected to the inner side of the bottom end of the rotating splint.
[0016] Working principle: First, the entire device is adsorbed on the iron device through the support legs, then the rotating splint is opened, the patient's injured part is placed on the fixed splint, and the wound is placed directly below the surgical incision on the rotating splint. Then, the rotating splint is closed, and the card strip is passed between the fixed block and the card plate. At this time, the locking teeth on the card strip will lift the card plate. When the bottom end of the card plate moves relatively between the two locking teeth, the torsion spring can make the bottom end of the card plate be stuck between the two locking teeth, thereby limiting the card strip and achieving the effect of fixing the rotating splint and the fixed splint together. , and then fix the patient's arm or calf. The air pump can inflate airbags 1 and 2. When airbag 1 is in an expanded state, it can squeeze the blood vessels in the patient's arm or calf, thereby improving the hemostatic effect. When airbag 2 is in an expanded state, airbag 2 can support the patient's arm or calf, thereby making the patient's arm or calf close to the surgical incision on the rotating splint, thereby facilitating the doctor to suture the patient's wound. After that, the patient's wound can be sutured from the surgical incision. The disinfectant liquid in the storage box can be touched by the nozzle through the infusion pump body, thereby spraying the disinfectant liquid on the patient's wound. The collection tank can be provided to collect the excess disinfectant liquid.
[0017] The present invention provides a magnetic-assisted minimally invasive suturing device for vascular surgery.
[0018] Beneficial effects:
[0019] 1. The present invention achieves efficient fixation and hemostasis through the cooperation of mechanical structure and airbag. First, the support legs are used to absorb iron components to ensure overall stability. The rotating splint and the fixed splint are tightly closed through the locking mechanism of the card strip, which can firmly fix the patient's arm or calf. At the same time, after the air pump inflates the airbag, the expanded airbag can directly squeeze the blood vessels of the injured area and quickly achieve the hemostasis effect. This dual fixation mode of "mechanical locking + airbag compression" not only ensures the stability of the injured area, but also improves the hemostasis efficiency through physical compression, reduces the risk of bleeding during surgery, and is particularly suitable for clinical scenarios that require emergency hemostasis.
[0020] 2. The present invention can support the wound after the airbag is inflated, so that the wound is accurately aligned with the surgical opening of the rotating splint, avoiding suturing deviation due to the movement of the patient's limbs; the infusion pump body drives the nozzle to spray disinfectant liquid, which can disinfect the wound in time, and the collection tank can recycle excess liquid to keep the operation area clean. In addition, the opening and closing design of the fixed splint and the rotating splint is matched with the card strip limiter, and the operation process is simple, and medical staff can quickly complete the fixation of the wound and preoperative preparation. Through functional integration, the device integrates the positioning of the wound, disinfection treatment and liquid collection, which not only optimizes the surgical operation process, but also reduces the risk of infection and improves the efficiency and safety of emergency or surgical operations.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] Example 1:
[0029] Please see the attached Figure 1 -Attached Figure 3The embodiment of the present invention provides a magnetic-assisted minimally invasive suturing instrument for vascular surgery, comprising a support platform 1, the top of the support platform 1 being U-shaped, the top of the support platform 1 being fixedly connected to a fixed splint 2, when performing a suturing operation, the doctor can place the patient's arm or calf on the fixed splint 2 of the support platform 1, thereby supporting the patient's arm or calf, the top of the fixed splint 2 being rotatably connected to a rotating splint 4, after the patient's arm or calf is placed, the rotating splint 4 is rotated down, so that the patient's arm or calf can be clamped by the rotating splint 4 and the fixed splint 2, the rotating splint 4 and the right outer wall of the fixed splint 2 are fixedly connected to a clamping strip 6, and the right outer wall of the rotating splint 4 is fixedly connected to a fixed block 11, The clamping strip 6 is then passed through between the fixing block 11 and the clamping plate 12. At this time, the locking teeth on the clamping strip 6 will push up the clamping plate 12. When the bottom end of the clamping plate 12 moves relatively between the two locking teeth, the torsion spring can make the bottom end of the clamping plate 12 be stuck between the two locking teeth, thereby limiting the clamping strip 6, achieving the effect of fixing the rotating splint 4 and the fixed splint 2 together, thereby fixing the patient's arm or calf. The middle end of the fixing block 11 is connected to the clamping plate 12 by the torsion spring, and the outer wall of the clamping strip 6 is fixedly connected to a plurality of locking teeth. The shape of the locking teeth is triangular, and the hypotenuse of the triangle faces upward, and the left side of the bottom end of the clamping plate 12 can be engaged with the locking teeth. The top side of the fixed splint 2 is provided with an air bag 2 13 and an air bag 1 7. When the air bag 1 7 is in expansion, When the airbag 2 13 is in an inflated state, the blood vessels at the patient's arm or calf can be squeezed, thereby improving the effect of hemostasis. When the airbag 2 13 is in an inflated state, the patient's arm or calf can be supported by the airbag 2 13, so that the patient's arm or calf is close to the surgical incision on the rotating splint 4, thereby making it convenient for the doctor to suture the patient's wound. The bottom end of the support platform 1 is connected to the bottom plate 15 by bolts, and the bottom plate 15 can be removed. The top of the bottom plate 15 is fixedly connected to a storage box 16, which is used to store disinfectant liquid. A drain port is provided at the bottom of the storage box 16, and the disinfectant liquid in the box body can be discharged through the drain port. The outer wall of the storage box 16 is also provided with an injection port. The port can inject disinfectant liquid into the storage box 16. The rear end of the storage box 16 is provided with an infusion pump body 17. The input end of the infusion pump body 17 is connected to the storage box 16. The output end of the infusion pump body 17 is fixedly connected to a hose 9. The end of the hose 9 away from the infusion pump body 17 is fixedly connected to a nozzle 10. The disinfectant liquid in the storage box 16 can be transported to the hose 9 through the infusion pump body 17, and then sprayed out by the hose 9 through the nozzle 10, so as to disinfect the skin near the wound. A plurality of air pumps 18 are fixedly connected to the middle of the top of the bottom plate 15, and the output ends of the air pumps 18 are fixedly connected to connecting pipes. The air pumps 18 can transport air to airbag 1 7 and airbag 2 13 through the connecting pipes, so as to expand airbag 1 7 and airbag 2 13.
[0030] Please see the attached Figure 3 -Attached Figure 5 The top of the rotating splint 4 is provided with a surgical port. By placing the patient's wound into the surgical port, the patient's arm and calf can be fixed while the doctor can suture the patient's wound. A collection tank 5 is provided on the left side of the surgical port. The collection tank 5 can collect the excess disinfectant sprayed by the nozzle 10. The right side of the surgical port is provided with scale lines. The scale lines can help the doctor more intuitively judge the suture position of the wound. There are two air pumps 18. One of the air pumps 18 is connected to the air bag 2 13 through a connecting tube. The air bag 2 13 can be inflated by the air pump 18. The other air pump 18 is connected to the air bag 1 7 through a connecting tube. The air bag 1 7 can be inflated by the air pump 18. The left outer wall of the fixed splint 2 is fixedly connected to the placement table 8. The bottom of the placement table 8 is fixedly connected to the left outer wall of the support table 1 through a support rod. The placement table 8 can facilitate the doctor to place the suture instrument on the placement table 8. The middle end of the right outer wall of the fixed splint 2 is fixedly connected to a limit block 14. A slot is provided on the right side of the limit block 14. When the nozzle 10 is not in use, the hose 9 can be inserted into the groove on the limit block 14 to fix the hose 9 and prevent the hose 9 from interfering with the doctor's suture operation. The bottom end of the base plate 15 is fixedly connected to the support leg 3. The bottom end of the support leg 3 is fixedly connected to a magnet. By providing the magnet, the entire device can be adsorbed onto an iron part, thereby fixing the entire device. There are two airbags 1 (7), which are located at the front and rear ends of the inner top of the fixed splint 2. When the airbags 1 (7) are inflated, they can squeeze the blood vessels in the patient's arm or calf, thereby improving the hemostasis effect. There is one airbag 2 (13), which is located at the middle end of the inner top of the fixed splint 2. When the airbag 2 (13) is inflated, the airbag 2 (13) can support the patient's arm or calf, thereby making the patient's arm or calf close to the surgical incision on the rotating splint 4, thereby facilitating the doctor to suture the patient's wound. A padding pad is fixedly connected to the inner bottom of the rotating splint 4. The padding pad can support the patient's arm or calf from the side, preventing the patient's arm or calf from tilting.
[0031] Example 2:
[0032] This embodiment adds a pressure sensing and automatic inflation system on the basis of the original structure. Pressure sensors 19 are embedded on the surfaces of airbag 1 7 and airbag 2 13 on the inner side of the fixed splint 2, and the sensors are electrically connected to the controller 20 in the base plate 15 through wires. The controller 20 is connected to the air pump 18 signal and can automatically adjust the inflation volume according to the pressure data. After the patient's limb is placed on the fixed splint 2, the rotating splint 4 is closed, and the pressure sensor 19 monitors the contact pressure between the airbag and the limb in real time. If the pressure is insufficient, such as when the limb moves and causes a gap, the controller 20 automatically starts the air pump 18 to replenish the gas to ensure that airbag 1 7 continues to compress the blood vessels to stop bleeding and airbag 2 13 stably supports the limb. In addition, a flexible pressure pad 21 is added to the edge of the surgical port of the rotating splint 4, and a pressure sensor is also integrated inside it to assist in judging whether the wound is aligned with the center of the surgical port to avoid suture deviation.
[0033] This embodiment utilizes pressure sensing and automatic inflation technology to dynamically adjust both hemostasis and support pressure, eliminating the need for manual, repetitive adjustment of the airbag pressure required with traditional devices. This design is particularly suitable for patients of varying body sizes or those experiencing mild limb swelling during surgery. It ensures sustained hemostasis while preventing tissue damage from excessive pressure, enhancing both the device's intelligence and safety.
[0034] Example 3:
[0035] This embodiment adds an ultraviolet disinfection module and an active waste liquid recovery system to the spray assembly. The specific structure is as follows: an ultraviolet disinfection lamp 22 is symmetrically installed on the inner edge of the surgical port of the rotating splint 4, and its power supply is supplied by the battery in the base plate 15; the bottom of the collection tank 5 is connected to the recovery pipe 24, and the end of the pipe is connected to the waste liquid recovery pump 23. The recovery pump is fixed to the bottom of the base plate 15 and can pump excess disinfectant liquid into the waste liquid tank 25 next to the storage box 16. During use, medical staff can start the ultraviolet disinfection lamp 22 through the control panel to perform preoperative sterilization of the surgical port area; after the infusion pump body 17 sprays the disinfectant liquid, the waste liquid recovery pump 23 is started synchronously, and the liquid is quickly collected through the recovery pipe 24 to avoid accumulation. In addition, a heating coil 26 is added between the storage box 16 and the infusion pump body 17 to preheat the disinfectant liquid to 37°C, reducing the irritation of the low-temperature liquid to the wound.
[0036] This embodiment utilizes ultraviolet disinfection and active waste fluid recovery technology to create an integrated "spraying-sterilization-recovery" sterile operating environment. The UV lamp enhances preoperative disinfection and reduces infection risk. The waste fluid recovery pump overcomes the limitations of passive liquid storage in traditional collection tanks, preventing spillage and contamination of the surgical area. The heating coil enhances patient comfort, making it particularly suitable for prolonged surgeries, embodying the user-friendly and integrated functionality of the instrument design.
[0037] Example 4:
[0038] In this embodiment, an adjustable magnetic support system is added between the base plate 15 and the support table 1. The specific structure is as follows: the top of the base plate 15 is connected to the support column 29 through a magnetic hinge seat 28, and the top of the support column 29 is detachably connected to the bottom of the support table 1 through an angle adjustment knob 27. The magnetic hinge seat 28 has a built-in permanent magnet that can be adsorbed on the surface of the iron operating table, while allowing the support column 29 to rotate within the range of 0-90°; the angle adjustment knob 27 can lock the tilt angle of the support table 1, with a maximum adjustment range of ±30°. During use, medical staff can adjust the tilt angle of the support table 1 by rotating the angle adjustment knob 27 according to the surgical position requirements, so that the wound is in the optimal operating position. The strong adsorption force of the magnetic hinge seat 28 ensures that the device remains stable after adjustment, avoiding position displacement due to patient movement or instrument vibration. In addition, a wire is pre-buried inside the support column 29 to connect the air pump 18 and the controller, if any, to ensure that the pipeline is not pulled during the angle adjustment process.
[0039] This embodiment solves the problem of traditional instruments being unable to flexibly adjust body position after fixation through a combined design of magnetic adsorption and angle adjustment. The support angle can be dynamically adjusted according to the direction of the blood vessels or the requirements of the surgical approach, making it particularly suitable for suturing operations in deep blood vessels or complex body positions. The strong adsorption characteristics of the magnetic articulated seat reduce the need for additional fixation devices and simplify the surgical preparation process. At the same time, the multi-angle adjustment capability improves the adaptability of the instrument to different surgical scenarios.
[0040] Example 5:
[0041] This embodiment integrates a biodegradable hemostatic membrane release system on the surface of the airbag 7. Specifically, a drug release reservoir 30 is provided on the surface of the airbag 7 on the inner side of the fixed splint 2. A biofilm carrier 31 is placed in the reservoir. The biofilm carrier 31 is made of a gelatin-chitosan composite membrane loaded with thrombin. A temperature-sensitive drug release valve 32 is provided at the outlet of the drug release reservoir 30. When the airbag 7 is inflated, the temperature-sensitive valve is triggered to open due to the body temperature of 37°C, and the biofilm carrier 31 adheres to the wound surface under the action of pressure. In addition, a dual-chamber structure is added to the storage box 16, one chamber storing disinfectant liquid and the other chamber storing antibiotic sustained-release agent. The dual-channel control of the infusion pump body 17 achieves the simultaneous operation of disinfection and drug sustained-release. After adhering to the wound, the biofilm carrier 31 can gradually degrade within 48-72 hours, releasing thrombin to promote hemostasis and forming a barrier to reduce the risk of infection.
[0042] This embodiment deeply integrates biomaterials and device functions, achieving a dual hemostatic mode of "mechanical compression hemostasis + biomaterial coagulation" through a temperature-sensitive drug release mechanism. Compared with traditional airbag compression, this significantly improves hemostatic efficiency and is particularly suitable for patients with poor coagulation function. The dual-chamber drug release system integrates disinfection and anti-inflammatory treatment, reducing the need for additional intraoperative drug administration. The biodegradable nature of the biofilm eliminates the need for secondary removal, reducing patient pain and infection risk, and embodying the precision and humane design of minimally invasive treatment.
