Description

Technical Field

[0001] This invention relates to the field of medical device technology, and specifically to a detachable separation forceps with hemostatic function. Background Technology

[0002] In laparoscopic minimally invasive surgery, dissecting forceps are an indispensable basic surgical instrument, widely used for operations such as traction, dissection, and separation of intra-abdominal tissues. Its structure typically includes an operating handle, a slender forceps bar, and a forceps head at the front end. By operating the handle, medical staff drive the forceps bar to transmit power, thereby opening and closing the forceps head, and thus completing the lifting and separation of diseased tissues, adhesions, or perivascular tissues in the intra-abdominal cavity. This facilitates subsequent operations such as surgical field exposure and lesion resection, and is one of the key instruments to ensure the smooth conduct of laparoscopic surgery.

[0003] Current laparoscopic dissecting forceps have a relatively limited function, only capable of basic tissue traction and separation. When tissue or blood vessel ruptures and bleeds due to improper intraoperative manipulation, medical staff must first use the dissecting forceps to clamp the bleeding point for temporary hemostasis. Then, an assistant must hold a separate hemostatic clamp and operate again through the gap between the dissecting forceps and the bleeding point to clamp the hemostatic clamp at the bleeding point or ruptured blood vessel. During this operation, due to the obstruction of the dissecting forceps and the narrow operating space and limited field of vision in the abdominal cavity, it is very easy to have the hemostatic clamp angle be inappropriate, resulting in the hemostatic clamp not being accurately aligned and clamped at the bleeding point or ruptured blood vessel. In some cases, it may be necessary to try to clamp the hemostatic clamp repeatedly. Repeated operation not only prolongs the hemostasis time, but also causes the temporarily controlled bleeding point to rupture again due to improper operation, significantly increasing the risk of massive intraoperative hemorrhage for the patient. At the same time, it also increases the difficulty of the operation and the workload of medical staff, affecting the efficiency and safety of the operation. Summary of the Invention

[0004] The main objective of this invention is to provide a detachable separation forceps with hemostatic function to overcome the problems existing in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A detachable separating forceps with hemostasis function includes a fixed handle, a pinch handle, a forceps body, and a forceps head. The fixed handle is rotatably connected to the pinch handle. One end of the forceps head is provided with two forceps bodies. The forceps body and the forceps head are inserted and interference-fitted. An operating component is provided between the fixed handle, pinch handle, forceps body, forceps head, and forceps bodies. The operating component includes an opening and closing unit and a disengagement unit. The opening and closing unit includes a lever, one end of which passes through the clamp body and the fixed handle and extends into the grip. Rotating the grip can pull the lever, thereby driving the two clamp bodies to perform opening and closing actions. The disengagement unit includes a lever and a hollow rod sleeved outside the pull rod. By rotating and pushing the lever, the hollow rod can be driven to move axially to release the interference fit between the pliers head and the pliers body, thereby disassembling the pliers head.

[0006] Furthermore, the pull rod is located inside the clamp body, and one end of it extends into the inside of the grip and is fixedly connected to two limit posts. The inside of the grip is provided with a fixing groove for the limit posts to be limited.

[0007] Furthermore, one end of the clamp head is fixedly connected to a first rotating shaft, and the roots of both clamp bodies are rotatably connected to the first rotating shaft via damping bearings.

[0008] Furthermore, each of the two clamp bodies has a connecting rod rotatably connected to one side, and the other end of the two connecting rods is rotatably connected to a connector via a second rotating shaft.

[0009] Furthermore, the end of the pull rod near the pliers head is inserted into the connector with an interference fit, and the outer wall of the connector is provided with a limiting groove extending along the axial direction, and slots are symmetrically provided on both sides of the limiting groove.

[0010] Furthermore, a limiting edge is fixedly provided at one end of the inner cavity of the pliers head near the pliers body, and openings are provided on both sides of the limiting edge.

[0011] Furthermore, the hollow rod is sleeved on the outside of the pull rod, and limit blocks are fixedly connected to both sides of the end near the pliers head. The hollow rod can rotate and move axially relative to the pull rod. When the hollow rod is in the initial position, the limit blocks at both ends pass through the corresponding slots and through holes respectively. The length of the limit block is the same as the axial length of the limit groove.

[0012] Furthermore, a top ring is fixedly fitted on the outer wall of the hollow rod. The outer diameter of the top ring is adapted to the inner diameter of the pliers body. Pushing the hollow rod can cause the top ring to abut against and push the pliers head away from the pliers body.

[0013] Furthermore, an L-shaped limiting groove is provided on the outer wall of the clamp body near the fixed handle. The lever is fixedly connected to the outer wall of the hollow rod and extends through the L-shaped limiting groove to the outside of the clamp body. A friction block is provided on the inner wall of the L-shaped limiting groove to provide damping when the lever moves to a specific position.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The disengagement unit in the operating assembly can quickly release the interference fit between the forceps head and the forceps body, enabling convenient disassembly and replacement of the forceps head. The hollow rod can rotate relative to the pull rod and move axially, ensuring that the opening and closing and disassembly actions do not interfere with each other. This further guarantees the smoothness, accuracy and safety of the disassembly operation. The entire operating assembly can complete hemostasis, forceps head replacement and subsequent surgical connection without interrupting the surgery, greatly improving surgical efficiency, reducing the workload of medical staff, and meeting the practical needs of clinical laparoscopic surgery. The opening and closing unit in the operating component allows for precise control of the two clamps via a pinch handle, enabling stable lifting and separation of intra-abdominal tissues. It also allows for quick and secure clamping of bleeding points during surgery, eliminating the need for an assistant to operate the hemostatic clamps separately, thus reducing the difficulty of hemostasis and the risk of rebleeding.

[0017] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Combination Figures 1 to 9 This embodiment provides a detachable separating forceps with hemostasis function, including a fixed handle 1, a pinch handle 2, a forceps body 3 and a forceps head 4. The fixed handle 1 is rotatably connected to the pinch handle 2. One end of the forceps head 4 is provided with two forceps bodies 6. The forceps body 3 is inserted into and pressurized with the forceps head 4. An operating component is provided between the fixed handle 1, the pinch handle 2, the forceps body 3, the forceps head 4 and the forceps body 6. The operating component includes an opening and closing unit and a disengagement unit. The opening and closing unit includes a pull rod 10. One end of the pull rod 10 passes through the clamp body 3 and the fixed handle 1 and extends into the grip 2. Rotating the grip 2 can pull the pull rod 10, thereby driving the two clamp bodies 6 to perform opening and closing actions. The disengagement unit includes a lever 21 and a hollow rod 17 sleeved outside the pull rod 10. By rotating and pushing the lever 21, the hollow rod 17 can be driven to move axially to release the interference fit between the pliers head 4 and the pliers body 3, thereby disassembling the pliers head 4.

[0019] Reference Figures 1-9 The pull rod 10 is located inside the clamp body 3. Limiting posts 19 are fixedly connected to both sides of one end extending into the handle 2. A fixing groove 18 for limiting the positions of the limiting posts 19 is provided inside the handle 2. A first rotating shaft 5 is fixedly connected to one end of the clamp head 4. The roots of both clamp bodies 6 are rotatably connected to the first rotating shaft 5 via damping bearings. Connecting rods 8 are rotatably connected to one side of each clamp body 6. The other ends of the two connecting rods 8 are rotatably connected to a connector 9 via a second rotating shaft 7. The end of the pull rod 10 near the clamp head 4 is inserted into the connector 9 with an interference fit. A limiting groove 11 extending axially is provided on the outer wall of the connector 9. Slots 12 are symmetrically provided on both sides of the limiting groove 11. A limiting edge 13 is fixedly provided in the inner cavity of the clamp head 4 near the clamp body 3. Through openings 14 are provided on both sides of the limiting edge 13. A hollow rod 17 is sleeved on the pull rod 10. Externally, limit blocks 16 are fixedly connected to both sides of the end near the jaw 4. The hollow rod 17 can rotate and move axially relative to the pull rod 10. When the hollow rod 17 is in the initial position, the limit blocks 16 at both ends pass through the corresponding slots 12 and through holes 14 respectively. The length of the limit block 16 is the same as the axial length of the limit groove 11. A top ring 15 is fixedly sleeved on the outer wall of the hollow rod 17. The outer diameter of the top ring 15 is adapted to the inner diameter of the jaw body 3. Pushing the hollow rod 17 can cause the top ring 15 to abut against and push the jaw 4 away from the jaw body 3. An L-shaped limit through groove 20 is opened on the side of the outer wall of the jaw body 3 near the fixed handle 1. The lever 21 is fixedly connected to the outer wall of the hollow rod 17 and extends through the L-shaped limit through groove 20 to the outside of the jaw body 3. A friction block is provided on the inner wall of the L-shaped limit through groove 20 to provide damping when the lever 21 moves to a specific position.

[0020] The operating components allow the lever 10 to engage with the handle 2, which in turn controls the two clamp bodies 6 to open and close, enabling tissue lifting and separation as well as clamping of bleeding points. The lever 21 can also be used to disengage the hollow rod 17 and top ring 15, releasing the interference fit between the clamp head 4 and the clamp body 3 and pushing the clamp head 4 away from the clamp body 3 for disassembly. Specifically, the clamp head 4 is first installed by aligning it with the clamp body 3 and inserting it directly. Initial fixation is achieved using the interference fit. At this point, the hollow rod 17 is in its initial position, and its end-end limiting block 16 passes sequentially through the through-hole 14 on the limiting edge 13 of the clamp head 4 and the slots 12 on both sides of the limiting groove 11 of the connector head 9. The length of the limiting block 16 is consistent with the axial length of the limiting groove 11. The design allows the limiting block 16 to fully fit the inner wall of the limiting groove 11, ensuring accurate insertion. After full insertion, the lever 21 is rotated 90 degrees along the L-shaped limiting through groove 20, causing the hollow rod 17 to rotate synchronously. This allows the limiting block 16 to rotate within the limiting groove 11 and form a misalignment with the slot 12, thus creating a reliable radial limit at the insertion point of the pull rod 10 and the connector 9, preventing relative slippage. The symmetrical structure of the through 14 and the slot 12 ensures that the hollow rod 17 is balanced in force during rotation and insertion, preventing offset after installation. Furthermore, the design of the top ring 15's outer diameter matching the inner diameter of the clamp body 3 allows the hollow rod 17 to move more smoothly axially within the clamp body 3, laying the foundation for subsequent operations. After installation, perform the closing clamping operation on the clamp body 6. Simply squeeze the handle 2 to rotate it relative to the fixed handle 1. The fixing groove 18 inside the handle 2 will drive the limiting post 19 at the end of the pull rod 10 to move synchronously. The engagement between the limiting post 19 and the fixing groove 18 ensures precise transmission without slippage, thereby stably pulling the pull rod 10 through the clamp body 3 to move axially. Because the end of the pull rod 10 near the clamp head 4 and the connector 9 are inserted with an interference fit, the tight fit structure allows the pull rod 10 to drive the connector 9 to move synchronously without falling off. After the connector 9 moves, it pulls the connecting rods 8 on both sides through the second rotating shaft 7. The connecting rods 8 then drive the two clamps 6, which are fulcrumd on the first rotating shaft 5, to close quickly. The design of the two clamps 6 being rotatably connected to the first rotating shaft 5 through the damping bearing at the base allows the clamps 6 to maintain a stable clamping state after closing, ensuring that the bleeding point is firmly clamped and does not loosen. The linkage structure between the connecting rod 8 and the first rotating shaft 5 and the second rotating shaft 7 makes the closing action of the clamps 6 smoother and the clamping force more uniform, which can accurately achieve tissue lifting and separation and effective clamping of the bleeding point. Finally, the pliers head 4 is disassembled. First, the lever 21 is rotated 90 degrees in the opposite direction, causing the hollow rod 17 to rotate synchronously, restoring the alignment of the limiting block 16 and the slot 12, releasing the radial limit. The friction block on the inner wall of the L-shaped limiting groove 20 provides damping positioning for the lever 21 in the rotating position, preventing accidental slippage during operation. Then, the lever 21 is pushed forward along the L-shaped limiting groove 20, causing the hollow rod 17 to move axially towards the pliers head 4 along the pull rod 10. The hollow rod 17 is designed to rotate relative to the pull rod 10 and move axially. This design ensures that the opening and closing and disassembly actions do not interfere with each other. During the movement, the top ring 15 on the hollow rod 17 moves forward synchronously and abuts against the pliers head 4. Continuously pushing the top ring 15 will apply a uniform pushing force to the pliers head 4, smoothly releasing the interference fit between the pliers head 4 and the pliers body 3, and finally pushing the pliers head 4 away from the pliers body 3 to complete the disassembly. The limiting edge 13 inside the pliers head 4 can also form an axial limit on the movement of the hollow rod 17 to prevent it from excessively extending into the pliers head 4 and causing damage to the components. The entire disassembly process is convenient to operate and the force is uniform, allowing for the quick replacement of the pliers head 4.

[0021] Through the coordinated operation of components such as the pull rod 10, limiting post 19, fixing groove 18, connector 9, connecting rod 8, first rotating shaft 5, and second rotating shaft 7, the opening and closing action of the two clamps 6 can be precisely controlled by the handle 2. This not only stably achieves the lifting and separation of intra-abdominal tissues, but also quickly and firmly clamps the bleeding point in case of intraoperative bleeding, eliminating the need for an assistant to operate a separate hemostatic clamp, reducing the difficulty of hemostasis and the risk of rebleeding. At the same time, the damping bearing design at the base of the two clamps 6 ensures stability and prevents loosening after clamping. The linkage structure makes the opening and closing action smooth and the clamping force uniform. The disengagement unit is connected by components such as the lever 21, hollow rod 17, limiting block 16, top ring 15, and L-shaped limiting groove 20. The system is designed so that simply rotating and pushing the lever 21 can quickly release the interference fit between the forceps head 4 and the forceps body 3, enabling convenient disassembly and replacement of the forceps head 4. The hollow rod 17 can rotate relative to the pull rod 10 and move axially, ensuring that the opening and closing and disassembly actions do not interfere with each other. The matching design of the top ring 15 and the forceps body 3, as well as the friction block design on the inner wall of the L-shaped limiting groove 20, further ensure the smoothness, accuracy, and safety of the disassembly operation. At the same time, the forceps head 4 is made of medical-grade plastic or titanium metal, which can be left in the body after surgery without any safety risks. The entire operating assembly can complete hemostasis, forceps head 4 replacement, and subsequent surgical connection without interrupting the surgery, greatly improving surgical efficiency, reducing the workload of medical staff, and meeting the practical needs of clinical laparoscopic surgery.

[0022] Working principle: First, before performing laparoscopic minimally invasive surgery, medical staff need to complete the preoperative preparation of instruments. In this scenario, the forceps head 4 is installed. After aligning the appropriate forceps head 4 with the forceps body 3, they are directly inserted. The interference fit is used to achieve the initial fixation of the two. At this time, the hollow rod 17 is in the initial position. The limiting block 16 at its end will pass through the through 14 on the limiting edge 13 of the forceps head 4 and the slots 12 on both sides of the limiting groove 11 of the connector head 9 in sequence. The design that the length of the limiting block 16 is consistent with the axial length of the limiting groove 11 allows the limiting block 16 to completely fit the inner wall of the limiting groove 11, ensuring accurate insertion and avoiding installation deviation from affecting the operation during surgery. After full insertion, the lever 21 is turned to rotate 90 degrees along the L-shaped limiting through groove 20, which drives the hollow rod 17 to rotate synchronously, so that the limiting block 16 rotates in the limiting groove 11 and forms a misalignment with the slot 12. This can form a reliable radial limit at the insertion point of the pull rod 10 and the connector head 9, preventing the two from slipping out. After the forceps head 4 is installed, the separating forceps are inserted into the abdominal cavity through the laparoscopic puncture port. At this time, the forceps can be used to perform routine lifting and separation functions to complete operations such as freeing adhesions in the abdominal cavity, pulling diseased tissues, and separating perivascular tissues, which facilitates the exposure of the surgical field and the resection of lesions. When tissue or blood vessel ruptures and bleeds due to improper intraoperative manipulation, the clamping operation of the forceps 6 is performed. Medical personnel simply need to quickly manipulate the dissecting forceps, aligning the two front clamps 6 with the bleeding point and initially clamping them. Then, the handle 2 is squeezed to rotate relative to the fixed handle 1. The fixing groove 18 inside the handle 2 will drive the limiting post 19 at the end of the pull rod 10 to move synchronously. The engagement between the limiting post 19 and the fixing groove 18 ensures precise transmission without slippage, thus stably pulling the pull rod 10, which runs through the forceps body 3, axially. Because the end of the pull rod 10 near the forceps head 4 is inserted into the connector 9 with an interference fit, the tight fit structure allows the pull rod 10 to drive the connector 9 simultaneously. The device moves without detaching. After the connector 9 moves, it pulls the connecting rods 8 on both sides through the second rotating shaft 7. The connecting rods 8 then drive the two clamps 6, which are fulcrumd on the first rotating shaft 5, to close quickly. The design of the two clamps 6 being connected to the first rotating shaft 5 through the damping bearing at the base allows the clamps 6 to maintain a stable clamping state after closing, ensuring that the bleeding point is firmly clamped and does not loosen. The linkage structure between the connecting rod 8 and the first rotating shaft 5 and the second rotating shaft 7 makes the closing action of the clamps 6 smoother and the clamping force more even. It can accurately achieve tissue lifting and separation and effective clamping of the bleeding point, eliminating the need for an assistant to hold the hemostatic clamp separately, reducing the difficulty of hemostasis and the risk of rebleeding. After hemostasis, the clamp head 4 has firmly clamped the bleeding point (blood vessel). Medical staff do not need to stop the operation. They only need to operate the lever 21 to rotate 90 degrees in the opposite direction so that the limiting block 16 at the end of the hollow rod 17 is aligned with the slot 12. This releases the radial limitation of the pull rod 10, the connector 9, and the clamp head 4. Then, the lever 21 is pushed forward along the L-shaped limiting through groove 20. The lever 21 will drive the hollow rod 17 and the top ring 15 to apply a pushing force to the clamp head 4, quickly releasing the interference fit between the clamp head 4 and the clamp body 3, and realizing the separation of the clamp head 4 from the rear rod body (clamp body 3, fixed handle 1, pinch handle 2, etc.).

[0023] Since the forceps head 4 is made of commonly used clinical plastic or titanium metal, which meets medical standards, it can remain in the human body for a long time after surgery without causing adverse effects on the human body.

[0024] After separation, medical staff remove the rear end of the forceps from the laparoscopic puncture port. Then, a new adapter head 4 can be installed on the rear end of the forceps and inserted back into the abdominal cavity to continue subsequent tissue lifting, separation and other surgical operations. The entire process does not require interruption of the surgery, making it convenient and efficient. It ensures the stability of hemostasis without affecting the progress of the surgery.

[0025] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
