Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an automated vaginal closure and cutting instrument for laparoscopy. Background Technology

[0002] With the rapid development of minimally invasive surgical techniques, laparoscopic surgery has become the mainstream surgical method for treating gynecological diseases due to its advantages such as minimal trauma and rapid postoperative recovery. However, in key procedures involving the vagina (such as closure and incision), the complexity of its anatomical structure (thin mucosa, rich blood supply, and deep proximity to vital organs) places extremely high demands on the precision and safety of the procedure. Clinically, there is an urgent need for new instruments that can balance "precise operation, reliable closure, and tissue protection" to reduce the risk of postoperative complications. In recent years, advancements in interdisciplinary fields such as artificial intelligence, sensor technology, and mechatronics have provided new opportunities for the development of intelligent, multifunctional laparoscopic vaginal surgical instruments, which are expected to drive the development of minimally invasive gynecology towards greater precision and safety.

[0003] With the rapid development of minimally invasive surgical techniques, laparoscopic surgery has become an important treatment method for benign and malignant gynecological diseases due to its advantages such as minimal trauma and rapid postoperative recovery. However, in surgeries involving tumors, the management of the vaginal stump—especially key steps such as closure and cutting—still faces significant challenges. The vaginal wall itself has a unique anatomical structure, with a thin mucosa, dense blood vessel distribution, and deep proximity to vital organs such as the rectum, bladder, and ureters, placing extremely high demands on the precision of surgical instrument manipulation, the reliability of closure, and the ability to protect tissues. Therefore, there is an urgent clinical need for a new type of surgical instrument that can integrate precise control, reliable closure, and tissue protection functions to reduce the risk of intraoperative and postoperative complications. In recent years, breakthroughs in artificial intelligence technology, high-precision sensing systems, and mechatronics technology have provided a solid technical foundation for the development of intelligent, multifunctional laparoscopic vaginal surgical instruments. These interdisciplinary integrations not only enhance the autonomy and adaptability of instruments but also further promote the development of minimally invasive gynecological tumor surgery towards greater precision, safety, and controllability. In existing techniques, because the vagina cannot be protected during surgery, tumor cells may be exposed to the abdominal cavity due to vaginal opening. Exfoliated tumor cells may be transported by irrigation fluid, blood, or instruments and implant in abdominal structures such as the intestines and greater omentum, causing abdominal implantation nodules and significantly reducing the patient's disease-free survival rate. At the same time, incomplete closure may result in tumor tissue remaining at the vaginal stump or incomplete vaginal wall, increasing the risk of local recurrence after surgery. In addition, normal vaginal flora entering the abdominal cavity can contaminate the surgery and increase the probability of complications such as abdominal infection and pelvic abscess.

[0004] However, current surgical techniques still lack specialized instruments capable of effectively protecting vaginal structures and adhering to the principle of tumor-free surgery. Prolonged vaginal closure during surgery can lead to tumor cells detaching and entering the abdominal cavity. These cells can migrate with irrigation fluids, blood, or instruments, implanting on the surface of abdominal organs such as the intestines and greater omentum, forming metastatic nodules and severely impacting the patient's tumor-free survival. Furthermore, incomplete closure of the vaginal stump can result in residual tumor tissue, increasing the risk of local recurrence after surgery. In addition, normal vaginal flora may invade the abdominal cavity during the procedure, contaminating the surgical area and causing abdominal infections or even pelvic abscesses, further exacerbating the patient's postoperative complication burden. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the prior art that the vagina cannot be protected during the operation, which may lead to the exposure of tumor cells in the peritoneal cavity due to vaginal opening. Therefore, an automatic vaginal closure and cutting instrument under laparoscopy is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automated vaginal closure and cutting instrument for laparoscopy, including an operating handle, and further comprising:

[0008] The sleeve is fixed to the outside of the output end of the operating handle;

[0009] Clamping assembly, located inside the sleeve;

[0010] A cutting component, located inside the clamping component, is used to cut the vagina;

[0011] The displacement control assembly includes a rotating sleeve, which is sleeved on the outside of the sleeve and slidably connected to the sleeve; the rotating sleeve is located on the sleeve at one end near the operating handle.

[0012] A liquid storage sleeve is installed at the end of the rotating sleeve away from the operating handle, and the liquid storage sleeve is slidably connected to the sleeve.

[0013] The squeezing assembly is located inside the liquid storage sleeve and is used to squeeze or draw out the filling water stored inside the liquid storage sleeve.

[0014] The adapter assembly is located at the inner end of the liquid storage sleeve;

[0015] A protective sleeve is provided, with one end of which is fixedly connected to the end of the liquid storage sleeve furthest from the operating handle; the end of the protective sleeve furthest from the liquid storage sleeve is open.

[0016] An adhesive component, located on the outside of the protective sleeve, is used to increase the fit between the protective sleeve and the vaginal stump;

[0017] A sealing assembly is disposed inside the opening end of the protective sleeve and is used to seal the inside of the protective sleeve.

[0018] Optionally, the clamping assembly includes a connector threaded into the inside of the sleeve at the end away from the operating handle. A clamp head is provided inside the connector. A limiting rod on the rotating end of the clamp head is fixedly connected to the inner wall of the connector. A gap is left between the two clamping arms in the clamp head for the cutting assembly to run. A transmission rod is fixedly connected to the driving end of the clamp head. The transmission rod passes through the sleeve. The end of the transmission rod away from the clamp head is fixedly connected to the operating end of the operating handle.

[0019] Optionally, the cutting assembly includes an electric push rod fixed to the inside of the transmission rod, with a blade fixedly connected to the output end of the electric push rod. The blade is slidably connected to the transmission rod and to the pliers head.

[0020] Optionally, a movable handle is provided at the end of the rotating sleeve near the operating handle, and the movable handle is slidably connected to the sleeve outside the sleeve.

[0021] Optionally, the extrusion assembly includes a threaded sleeve threadedly connected to the liquid storage sleeve, a connecting ring rotatably connected to the end of the threaded sleeve away from the operating handle, the connecting ring being slidably connected to the inner wall of the liquid storage sleeve, and a piston ring fixedly connected to the end of the connecting ring away from the operating handle, the piston ring being slidably connected to the inner wall of the liquid storage sleeve.

[0022] Optionally, the adapter assembly includes a sealing ring rotatably connected to the inner side of the end of the liquid storage sleeve away from the operating handle and a sliding groove opened on the outer end wall of the end of the liquid storage sleeve away from the operating handle. Two connecting holes are symmetrically opened on the inner side of the sealing ring, and a rotating handle is fixedly connected to the top of the sealing ring that protrudes outside the liquid storage sleeve.

[0023] Optionally, the bonding assembly includes a first connecting tube symmetrically arranged at the end of the liquid storage sleeve away from the operating handle. The first connecting tube is fixedly connected to the protective sleeve. The end of the first connecting tube away from the liquid storage sleeve is fixedly connected to a bonding water bladder. The bonding water bladder is fixedly connected to the outer wall of the protective sleeve away from the liquid storage sleeve. The protective sleeve is fitted over the sleeve.

[0024] Optionally, the sealing assembly includes a second connecting pipe symmetrically arranged at the end of the liquid storage sleeve away from the operating handle. The second connecting pipe is fixedly connected to the protective sleeve. A sealing water bladder is fixedly connected to the end of the second connecting pipe away from the liquid storage sleeve. The two sides of the sealing water bladder are fixedly connected to the end sidewalls of the open end of the protective sleeve. The two sealing water bladders are symmetrically arranged and are fixedly connected to the second connecting pipes on both sides respectively. The sleeve can pass through the two sealing water bladders.

[0025] Optionally, the extension length of the electric push rod is the same as the clamping length of the clamping arm of the pliers.

[0026] Optionally, the liquid storage sleeve and the protective sleeve are connected by a flexible material.

[0027] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0028] In the above scheme, by setting a movable protective sleeve on the outside of the cannula and using an adhesive component to make the protective sleeve fit tightly against the vaginal stump, the risk of tumor cells entering the abdominal cavity through the open vagina is effectively blocked, significantly reducing the probability of peritoneal seeding and metastasis during malignant tumor surgery. The sealing of the adhesive component isolates the direct communication between the vagina and the abdominal cavity, avoiding contamination of the surgical field by vaginal flora or secretions, reducing the incidence of postoperative complications such as abdominal infection and pelvic abscess. The tight fit between the protective sleeve and the vaginal stump provides stable support and guidance for instrument operation, reducing instrument displacement caused by narrow pelvic space or tissue movement, while also preventing accidental collapse of the vaginal wall.

[0029] By rotating the adapter, the liquid storage sleeve can be connected to the sealing component, so that after the tissue is removed, it can be pulled into the protective sleeve and sealed to prevent the tissue from contacting the vagina. Through physical sealing and isolation, direct contact between the removed lesion and the vagina and abdominal cavity is effectively blocked, preventing tumor cells attached to the lesion surface from falling off and implanting in the vaginal wall or abdominal cavity, significantly reducing the risk of peritoneal implantation and metastasis, and providing core safety guarantee for radical surgery of malignant tumors.

[0030] The electric actuator moves the blade laterally, allowing for precise cutting of the tissue after it is gripped by the forceps. This eliminates the need for external equipment, reduces the need to interrupt the procedure or switch tools, significantly shortens the cutting time per session, and improves surgical efficiency. The precise displacement control of the electric actuator, combined with the stable gripping of the forceps, effectively controls the cutting depth and position, avoiding errors caused by heat diffusion from external equipment or manual shaking, thus enhancing cutting accuracy. The physical shearing of the mechanical blade causes no additional thermal damage, better protecting the thin vaginal mucosa and surrounding delicate tissues, while also preventing accidental cutting due to tissue displacement, reducing the risk of bleeding or collateral damage. The integrated internal design eliminates the need for external power supply or equipment, minimizing surgical field interference and maintaining a clean surgical field. Attached Figure Description

[0049] like Figures 1 to 10As shown, this embodiment of the invention provides an automated vaginal closure and cutting instrument for laparoscopy, including an operating handle 1. The operating handle 1 includes an output end and an operating end. Manipulating the operating section allows the components connected to the operating end to extend and retract. This is prior art and will not be described in detail here. It also includes:

[0050] Sleeve 11 is fixed to the outside of the output end of operating handle 1, and the operating handle 1 supports and fixes sleeve 11.

[0051] The clamping component is located inside the sleeve 11. The sleeve 11 supports and limits the clamping component. The laparoscopic forceps and laparoscopic instruments composed of the operating handle 1, sleeve 11 and clamping component are existing technologies. Referring to existing laparoscopic grasping forceps, they will not be described in detail. They are used for minimally invasive surgery.

[0052] A cutting component, located inside the clamping component, is used to cut the vagina;

[0053] The output end of the operating handle 1 is connected to a sleeve 11. The rotating sleeve 5 is fitted outside the sleeve 11 and is slidably connected to the sleeve 11. A movable handle 51 is provided at one end of the rotating sleeve 5 near the operating handle 1. The movable handle 51 is fitted outside the sleeve 11 and is slidably connected to the sleeve 11.

[0054] Liquid storage sleeve 3; installed at the end of the rotating sleeve 5 away from the operating handle 1, and the liquid storage sleeve 3 is slidably connected to the sleeve 11;

[0055] The displacement control component is located outside the sleeve 11, and its end is connected to the liquid storage sleeve 3. The displacement control component controls the movement and rotation of the prefabricated connected structure.

[0056] The squeezing component is located inside the liquid storage sleeve 3 and is used to squeeze or draw out the filling water stored in the liquid storage sleeve 3.

[0057] The adapter assembly is located at the inner end of the liquid storage sleeve 3;

[0058] Protective sleeve 4 is installed on the end of liquid storage sleeve 3 away from the operating handle 1;

[0059] An adhesive component is provided on the outside of the protective sleeve 4 to increase the fit between the protective sleeve 4 and the vaginal stump;

[0060] The sealing component is located inside the outer end of the protective sleeve 4 and is used to seal the inner side of the protective sleeve 4. The filling water in the liquid storage sleeve 3 is squeezed by the squeezing component, so that the filling water enters the bonding component and the sealing component respectively.

[0061] like Figures 1 to 4As shown, the clamping assembly includes a connector 12 threadedly connected to the end of the sleeve 11 away from the operating handle 1. The connector 12 is fixed by the sleeve 11. A pliers head 14 is provided inside the connector 12. The connector 12 supports and limits the pliers head 14. A limiting rod on the rotating end of the pliers head 14 is fixedly connected to the inner wall of the connector 12. In this solution, the limiting rod is a component on the pliers head 14 that limits the clamping arms on both sides, similar to the rivet in the middle of scissors. The limiting rods on both sides of the jaw head 14 are individually supported and limited by the connector 12. Simultaneously, the clamping arms on both sides of the jaw head 14 are rotatably connected to the inner wall of the connector 12 via the limiting rods, thus supporting the clamping arms on both sides of the jaw head 14. A gap is left between the two clamping arms in the jaw head 14 for the cutting assembly to operate. A transmission rod 13 is fixedly connected to the drive end of the jaw head 14, passing through the sleeve 11. The end of the transmission rod 13 away from the jaw head 14 is fixedly connected to the output end of the operating handle 1. The extension and retraction of the transmission rod 13 are controlled by the operating handle 1, thereby connecting the transmission rod 13 to the drive end on the jaw head 14 to drive the jaw head 14, realizing the clamping and releasing actions. The specific principle is similar to having a rotating component between the transmission rod 13 and the limiting rod. The extension and retraction of the transmission rod 13, along with the rotation of the limiting rod via the rotating component, causes the jaw head 14 to clamp and release. This is existing technology and will not be elaborated further.

[0062] like Figures 1 to 5 As shown, the cutting assembly includes an electric push rod 2 fixed inside the transmission rod 13. The electric push rod 2 is supported and fixed by the transmission rod 13. A blade 21 is fixedly connected to the output end of the electric push rod 2. The blade 21 is supported and fixed by the electric push rod 2. At the same time, the electric push rod 2 drives the blade 21 to move inside the transmission rod 13. The blade 21 is slidably connected to the inside of the transmission rod 13 and to the pliers head 14. The blade 21 slides between the gaps left between the clamping arms on both sides of the pliers head 14 and is not affected by the operation of the pliers head 14.

[0063] like Figures 1 to 6 As shown, the displacement control assembly includes a rotating sleeve 5 that slides on the outside of the sleeve 11. The rotating sleeve 5 is limited by the operating handle 1, so that the rotating sleeve 5 can move and rotate on the outside of the sleeve 11. A movable handle 51 is fixedly connected to the outer end of the rotating sleeve 5 near the operating handle 1. The movable handle 51 is supported and fixed by the rotating sleeve 5. The movable handle 51 is slidably connected to the sleeve 11. The movable handle 51 is limited by the operating handle 1. The rotating sleeve 5 can be moved synchronously by rotating or pushing and pulling the movable handle 51.

[0064] like Figures 1 to 10As shown, the extrusion assembly includes a threaded sleeve 31 that is threaded to the inner side of one end of the liquid storage sleeve 3. The threaded sleeve 31 is limited by the liquid storage sleeve 3. The liquid storage sleeve 3 is sleeved and fixed on the outer wall of the rotating sleeve 5. One end of the threaded sleeve 31 extends into the liquid storage sleeve 3 and is threadedly connected to the liquid storage sleeve 3. The other end of the threaded sleeve 31 extends out of the liquid storage sleeve 3 and has a gap with the rotating sleeve 5.

[0065] The threaded sleeve 31 can move laterally within the liquid storage sleeve 3 by rotation. A connecting ring 32 is rotatably connected to the end of the threaded sleeve 31 away from the operating handle 1. The connecting ring 32 is slidably connected to the inner wall of the liquid storage sleeve 3. A piston ring 33 is fixedly connected to the outer end of the connecting ring 32 away from the operating handle 1. The threaded sleeve 31 and the piston ring 33 are connected through the connecting ring 32. The lateral movement of the threaded sleeve 31 within the liquid storage sleeve 3 drives the connecting ring 32 and the piston ring 33 to move synchronously, thereby squeezing or extracting the filling water in the liquid storage sleeve 3. The piston ring 33 is slidably connected to the inner wall of the liquid storage sleeve 3.

[0066] like Figures 1 to 2 and Figures 7 to 10 As shown, the adapter assembly includes a sealing ring 34 rotatably connected to the inner side of the end of the liquid storage sleeve 3 away from the operating handle 1. The liquid storage sleeve 3 limits the sealing ring 34. A groove 37 is formed on the outer end wall of the liquid storage sleeve 3 away from the operating handle 1. Two connecting holes 35 are symmetrically formed on the inner side of the sealing ring 34. Rotating the sealing ring 34 causes the connecting holes 35 to rotate synchronously, so that the connecting holes 35 can be connected to the sealing assembly and the bonding assembly individually, thereby delivering filling water into the sealing assembly or the bonding assembly. A rotating handle 36 is fixedly connected to the top of the sealing ring 34 protruding outside the liquid storage sleeve 3. By turning the rotating handle 36, the sealing ring 34 rotates inside the liquid storage sleeve 3. The rotation angle of the rotating handle 36 is limited by the groove 37, so that the connecting holes 35 can be aligned with the water inlet end of the sealing assembly and the bonding assembly. When the rotating handle 36 abuts against the inner wall of the groove 37, the groove 37 limits the rotating handle 36.

[0067] The fitting assembly includes two first connecting pipes 42 symmetrically arranged at the end of the liquid storage sleeve 3 away from the operating handle 1. The two first connecting pipes 42 are symmetrical with respect to the axis of the liquid storage sleeve 3. The protective sleeve 4 is sleeved on the outside of the sleeve 11 and is located at the end of the liquid storage sleeve 3 away from the rotating sleeve 5. The first connecting pipes 42 are fixedly connected to the protective sleeve 4, and the protective sleeve 4 supports and fixes the first connecting pipes 42. The end of the first connecting pipe 42 extends towards the liquid storage sleeve 3. Turning the rotating handle 36 drives the two connecting holes 35 to rotate. When the rotating handle 36 abuts against the inner wall of one end of the slide groove 37, the two connecting holes 35 communicate with the two first connecting pipes 42 respectively, so that the first connecting pipes 42 are connected to the inside of the liquid storage sleeve 3, allowing the filling water inside the liquid storage sleeve 3 to enter the first connecting pipes 42.

[0068] like Figures 1 to 10 As shown, the end of the first connecting tube 42 furthest from the liquid storage sleeve 3 is fixedly connected to a conforming water bag 41. The conforming water bag 41 is fixedly connected to the outer wall of the protective sleeve 4 furthest from the liquid storage sleeve 3. The conforming water bag 41 is arc-shaped and surrounds the outer wall of the protective sleeve 4. Water from the liquid storage sleeve 3 can be transported into the conforming water bag 41 through the first connecting tube 42. The expansion of the conforming water bag 41 allows it to conform more tightly to the vaginal wall. One end of the protective sleeve 4 is fixedly connected to the liquid storage sleeve 3.

[0069] The sealing assembly includes two second connecting pipes 44 symmetrically arranged at the end of the liquid storage sleeve 3 away from the operating handle 1. The two second connecting pipes 44 are symmetrical with respect to the axis of the liquid storage sleeve 3. The second connecting pipes 44 are fixedly connected to the protective sleeve 4. Two first connecting pipes 42 and two second connecting pipes 44 are arranged around the protective sleeve 4. The ends of the second connecting pipes 44 extend toward the liquid storage sleeve 3. Turning the rotating handle 36 causes the two connecting holes 35 to rotate. When the rotating handle 36 abuts against the inner wall of the other end of the slide groove 37, the two connecting holes 35 communicate with the two second connecting pipes 44 respectively, so that the second connecting pipes 44 are connected to the inside of the liquid storage sleeve 3, allowing the filling water inside the liquid storage sleeve 3 to enter the second connecting pipes 44. The second connecting pipe 44 is fixedly connected to a sealing water bladder 43 at the end away from the liquid storage sleeve 3. The protective sleeve 4 is open at the end away from the liquid storage sleeve 3. Two sealing water bladders 43 are placed inside the opening of the protective sleeve 4, and when the two sealing water bladders 43 expand, they can seal the opening of the protective sleeve 4. The two sides of the sealing water bladders 43 are fixedly connected to the end wall of the protective sleeve 4 away from the liquid storage sleeve 3. The two sealing water bladders 43 are symmetrically arranged and are fixedly connected to the second connecting pipes 44 on both sides. The liquid storage sleeve 3 and the sealing water bladders 43 are connected through the second connecting pipes 44. The sleeve 11 passes between the two sealing water bladders 43.

[0070] In the initial state, the two sealing water bags 43 are not inflated, and the protective sleeve 4 is in an open state. Since the sleeve 11 is slidably connected to the protective sleeve 4, the rotating sleeve 5 and the liquid storage sleeve 3, and is also fixedly connected to the operating handle 1, moving the operating handle 1 backward will drive the sleeve 11 and the forceps head 14 to move backward relative to the protective sleeve 4, the rotating sleeve 5 and the liquid storage sleeve 3. During the movement, the forceps head 14 will enter the protective sleeve 4 from the opening. After the forceps head 14 drags the cut tissue into the protective sleeve 4, the clamping and releasing function of the forceps head 4 will allow the excised tissue to enter the protective sleeve 4. At this time, rotating the handle 36 will connect the liquid storage sleeve 3 with the second connecting tube 44. Then rotating the threaded sleeve 31 will allow the filling water to enter the sealing water bag 43 from the second connecting tube 44, causing the sealing water bag 43 to expand and block the opening of the protective sleeve 4, thus sealing the protective sleeve 4 and preventing the tissue from contacting the vagina during the removal process.

[0071] The extension length of the electric push rod 2 is the same as the length of the clamping part of the pliers head 14. By setting the extension length of the electric push rod 2 to be the same as the length of the clamping part of the pliers head 14, the blade 21 can be prevented from extending too far and damaging other tissue parts.

[0072] The inner wall of the liquid storage sleeve 3 and the protective sleeve 4 are fixedly connected by a flexible material. By setting a flexible material between the liquid storage sleeve 3 and the protective sleeve 4 for connection, the liquid storage sleeve 3 and the protective sleeve 4 can be rotated and bent at an angle, which facilitates the angle adjustment of the device during the operation, that is, it is convenient to adjust the operating angle of the laparoscopic forceps.

[0073] The working process of the technical solution provided by this invention is as follows:

[0074] When using this invention, firstly, the protective sleeve 4 is inserted into the patient's vagina. At this time, the sleeve 11 and the forceps 14 are controlled to be inside the protective sleeve 4 by the operating handle 1. Then, the rotating handle 36 is rotated, which drives the sealing ring 34 and the connecting hole 35 to rotate, so that the connecting hole 35 is aligned with the first connecting tube 42. Then, the threaded sleeve 31 is rotated, which drives the piston ring 33 to move away from the operating handle 1 by the connecting ring 32, thereby squeezing the filling water stored in the liquid storage sleeve 3. The filling water is then transported into the fitting water bag 41 through the first connecting tube 42, so that the fitting water bag 41 expands and fits tightly against the vaginal wall.

[0075] Then, the control handle 1 uses the sleeve 11 to drive the connector 12, transmission rod 13 and forceps 14 to penetrate into the predetermined position inside the vagina and clamp the predetermined position. The clamping is existing technology and will not be described in detail here. Drive the drive end of the control handle 1, and drive the blade 21 to move away from the control handle 1 through the transmission rod 13 and the electric push rod 2 to cut the clamped tissue. Then, move the control handle 1 backward to drive the sleeve 11 and forceps 14 backward. The forceps 14 drives the cut tissue to move into the protective sleeve 4 and stores the excised tissue through the protective sleeve 4.

[0076] After the cutting is completed, the forceps 14 is pulled into the protective sleeve 4. By rotating the handle 36, the sealing ring 34 and the connecting hole 35 are rotated, so that the connecting hole 35 is connected to the second connecting pipe 44. The threaded sleeve 31 is rotated again to transport the filling water in the liquid storage sleeve 3 into the sealing water bladder 43 through the second connecting pipe 44, so that the sealing water bladder 43 expands, thereby sealing the opening at the end of the protective sleeve 4, thus preventing the tissue stored inside from contacting the vagina.

[0077] Then rotate the sealing ring 34 again to connect the connecting hole 35 with the first connecting pipe 42, and then rotate the threaded sleeve 31 in the opposite direction to draw the filling water in the fitting water bag 41 back into the liquid storage sleeve 3, so that the fitting water bag 41 contracts and the protective sleeve 4 can be pulled out from the vagina as a whole.
