Abstract
Description
TECHNICAL FIELD
[0001] The present disclosure belongs to the field of tumor treatment equipment, and particularly relates to a gynecological surgery pelvic tumor extraction forceps. BACKGROUND
[0002] At present, in gynecological surgery, pelvic tumor extraction forceps are often used when pelvic tumors are removed. The extraction forceps are precision instruments specially designed for safe removal of pelvic tumors.
[0003] During surgery, medical staff need to control the clamping of the tumor by pressing the handle of the extraction forceps. However, during the operation, medical staff need to use a variety of instruments for auxiliary work, and each instrument requires different pressing force. Some instruments need a larger pressing force to function, but the extraction forceps require a smaller pressing force. Therefore, when switching from the instrument with a larger pressing force to the extraction forceps, the medical staff may form a muscle memory of clamping with great force to press the extraction forceps. The pressing force cannot be buffered, resulting in a larger initial pressing force of the clamping head, a larger clamping force on the tumor, and the tumor being clamped and broken, or tumor metastasis. SUMMARY

[0008] Preferably, the positioning assembly comprises a threaded positioning rod and a spring push rod, the spring push rod is movably arranged in the inside of the connecting base, both ends of the spring push rod are connected with the limiting frame and the clamping assembly respectively, the threaded positioning rod is screwed on the connecting base, and one end of the threaded positioning rod is attached to the surface of the spring push rod.
[0009] Preferably, the clamping assembly comprises a threaded sleeve and a fixed rod, the threaded sleeve is screwed on the inside of the connecting base, the fixed rod is fixedly arranged at one end of the threaded sleeve, two clamping heads are rotatably connected to the inner wall of the threaded sleeve, two connecting rods are rotatably connected to the outer wall of the spring push rod, and the inner walls of the two connecting rods are rotatably connected with the outer walls of the two clamping heads.
[0010] Preferably, the buffer assembly comprises an air pressure cylinder arranged in the inside of the connecting base and a sliding groove opened on the handle, a sliding block is slidably arranged on the inner wall of the sliding groove, a spring piston block is arranged at one end of the sliding block, and the spring piston block is slidably connected to the inner wall of the air pressure cylinder.
[0011] Preferably, the blocking assembly comprises a limiting block fixed in the inside of the connecting base and an inclined block arranged on the sliding block, a spring blocking block sleeved on the air pressure cylinder is movably connected to the bottom of the limiting block, throttle holes are opened on both sides of the top outer wall of the air pressure cylinder, a sealing rod is arranged on the top inner wall of the spring blocking block close to the lower side of the limiting block, and the sealing rod is inserted into the inner wall of the corresponding throttle hole.
[0012] Preferably, a connecting rod is arranged on the surface of the spring blocking block, and one end of the connecting rod is attached to the end inclined surface of the inclined block.
[0013] Preferably, the blocking assembly includes a piston cylinder installed inside the connecting base and an L-shaped rod installed at one end of the sliding block. The piston cylinder is provided with piston ring one and piston ring two. One end of the L-shaped rod passes through piston ring two and piston ring one and is located inside the piston cylinder. One end of the L-shaped rod is fixedly connected to piston ring one and slidably connected to piston ring two.
[0014] Preferably, a mounting hole is provided on one side of the outer wall of the piston cylinder, and an air nozzle is fixedly connected to the mounting hole.
[0015] The beneficial effects of this disclosure are: In use, when medical personnel need to grasp a tumor, they hold the connecting base and the handle, then press the handle to rotate, pushing the spring push rod to move and pulling the clamping assembly to move, allowing the two clamping heads to grasp the tumor. During the rotation of the handle, the spring piston block moves, compressing the gas on the left side and creating negative pressure on the right side, thus increasing the resistance when the spring piston block moves to one side. This provides timely resistance feedback when medical personnel press the handle forcefully, allowing them to perceive that they are applying too much pressure to the extraction forceps and begin to reduce force to avoid damaging the tumor. Simultaneously, the movement of the sliding block moves the blocking assembly, and the movement of the inclined block lifts the connecting rod, thereby limiting the movement. As the block is compressed upwards, the spring-loaded block rises, and the sealing rod rises upwards, opening the throttling orifice on the left side. Gas moves from the left side of the pneumatic cylinder through the two throttling orifices to the right side, removing the obstruction and allowing the spring-loaded piston block to move smoothly. This connects the two air chambers on both sides of the pneumatic cylinder, and the air pressure begins to balance. The resistance on the handle decreases, slowing the movement speed of the spring-loaded piston block and reducing the rotation speed of the handle. As the resistance decreases further, medical staff begin to reduce their force due to the initial resistance, making it easier for them to control the extraction forceps. This allows the clamping head to slowly contact the tumor, effectively preventing excessive initial pressure on the handle and avoiding the clamping head rapidly approaching the tumor, thus preventing the tumor from being crushed and ensuring the integrity of the tumor removal.
[0016] When the sliding block moves, it drives the L-shaped rod to move, causing piston ring 1 to move and compress the gas in the piston cylinder, increasing the gas pressure until the gas on the left side of piston ring 1 pushes piston ring 2 to move. When piston ring 1 compresses the gas, the resistance to the gas on piston ring 1 gradually increases. When the gas pushes piston ring 2 to move, the gas resistance on piston ring 1 remains stable. This ensures that medical personnel are blocked by stable gas resistance during subsequent pressing of the handle, effectively preventing the spring block from separating from the throttle orifice and the resistance to the spring piston block from disappearing, thus avoiding a sudden decrease in pressing resistance. This allows medical personnel to accurately control the pressing force of the handle. When the piston ring 2 moves, it compresses the gas inside the piston cylinder and ejects it through the nozzle. Since the medical staff's hands need to be held at the nozzle, the gas ejected from the nozzle will come into contact with the medical staff's hands. When the piston ring 2 moves at a faster speed, it will compress the gas and eject it quickly from the nozzle. The hand will feel a stronger airflow impact, which will be fed back to the medical staff to the current pressing speed, prompting them to slow down their movements and assisting the medical staff to control the contact between the clamping head and the tumor with a more stable pressing speed. When the gripping head needs to be loosened to adjust its position, medical staff need to release the handle. Once the pushing force on the handle disappears, the spring piston block's rebound force is released, causing it to return to its original position. This compresses the gas on the right side of the spring piston block, which is then ejected from the throttle orifice. As the gas exits from the throttle orifice, it consumes the elastic potential energy of the spring piston block, causing it to slowly return to its original position. This effectively prevents the spring piston block from accumulating strong rebound force. Furthermore, the high-pressure gas between piston ring one and piston ring two is also released, thus avoiding vibration during the spring piston block's return process. This stabilizes the gripping head and prevents it from puncturing the tumor. Attached Figure Description

Detailed Implementation
[0020] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.
[0021] Those skilled in the art will understand that the expressions relating to direction are used herein for the sake of descriptive convenience only, and are not intended to impose an absolute limitation on the direction of the novel pin-disc friction pair device.
[0022] Based on the concept of this application, combined with Figures 1 to 9 This describes a gynecological surgical pelvic tumor extraction forceps. The main body of the device consists of a connecting base 111, a handle 112, a positioning component 12, and a clamping component 21. It relies on a pneumatic buffer component 22 to generate resistance through air pressure. When medical staff press the handle forcefully, they can receive timely resistance feedback, thereby allowing them to perceive that they are pressing the extraction forceps too hard and begin to reduce their force to avoid damaging the tumor clamping.
[0023] Please refer to Figures 1 to 9 A gynecological surgical forceps for extracting pelvic tumors, comprising: The main body 1 includes a frame assembly 11 and a positioning assembly 12 that is slidably disposed inside the frame assembly 11. The frame assembly 11 includes a connecting base 111 and a handle 112 that is rotatably connected to the inside of the connecting base 111. The clamping mechanism 2 includes a clamping component 21 and a pneumatic buffer component 22. The clamping component 21 is installed at one end of the positioning component 12, and the pneumatic buffer component 22 is installed on the inner side of the frame component 11. The pneumatic buffer component 22 is slidably connected to the handle 112. When the handle 112 is pressed, the air pressure inside the pneumatic buffer component 22 changes, causing the handle 112 to be resisted when pressed. The damping mechanism 3 includes a blocking component 31 and a blocking component 32 disposed inside the frame assembly 11. The blocking component 31 is connected to the air pressure buffer assembly 22, and the blocking component 32 is connected to the air pressure buffer assembly 22.
[0024] During operation, the tumor is grasped by the extraction forceps. Medical staff press the handle 112 to pull the clamping component 21 to move, so that the clamping component 21 closes and grasps the tumor. During the pressing process, the air pressure buffer component 22 increases the initial resistance when pressing the handle 112, so that the clamping head 213 slowly contacts the tumor. This effectively prevents the medical staff from pressing the handle 112 with too much force at the beginning, thereby avoiding the clamping component 21 from quickly approaching the tumor and causing the tumor to be crushed. After the medical staff presses the handle 112 to a certain extent, the blocking component 31 will open the air pressure buffer component 22, so that the air pressure on both sides of the air pressure buffer component 22 is balanced. After the medical staff adjusts the grip force under pressure for the first time, the movement of the blocking component 31 reduces the resistance, which makes it easier for the medical staff to control the extraction forceps more accurately. The blocking component 32 is used to assist the work of the air pressure buffer component 22 and the blocking component 31, so that the medical staff can use the extraction forceps better.
[0025] Specifically, a limit frame 113 is installed at one end of the grip 112 near the positioning component 12, and one end of the positioning component 12 is connected to the limit frame 113.
[0026] When medical staff use the extraction forceps, they press the handle 112. The handle 112 drives the positioning component 12 through the limiting frame 113. The positioning component 12 pulls the clamping component 21, thereby tightening the extraction forceps and performing clamping work.
[0027] Furthermore, the positioning assembly 12 includes a threaded positioning rod 121 and a spring push rod 122. The spring push rod 122 is movably installed inside the connecting base 111. Both ends of the spring push rod 122 are connected to the limiting frame 113 and the clamping assembly 21, respectively. The threaded positioning rod 121 is screwed onto the connecting base 111, and one end of the threaded positioning rod 121 is in contact with the surface of the spring push rod 122.
[0028] After the tumor is clamped and fixed by the clamping assembly 21, the spring push rod 122 is fixed by the threaded positioning rod 121 to ensure that the spring push rod 122 does not move.
[0029] It should be noted that the clamping assembly 21 includes a threaded sleeve 211 and a fixing rod 212. The threaded sleeve 211 is screwed onto the inner side of the connecting base 111, and the fixing rod 212 is fixedly installed on one end of the threaded sleeve 211. Two gripping heads 213 are rotatably connected to the inner wall of the threaded sleeve 211, and two connecting rods 214 are rotatably connected to the outer wall of the spring push rod 122. The inner walls of the two connecting rods 214 are rotatably connected to the outer walls of the two gripping heads 213.
[0030] When the spring push rod 122 moves, it pulls the connecting rod 214 to move, causing the connecting rod 214 to rotate and bringing the far ends of the two connecting rods 214 closer together. The two connecting rods 214 will then pull the two gripping heads 213 to rotate, bringing the far ends of the two gripping heads 213 closer together to grip the tumor.
[0031] Furthermore, the buffer assembly 22 includes a pneumatic cylinder 221 installed inside the connecting base 111 and a sliding groove 224 opened on the handle 112. A sliding block 223 is slidably disposed on the inner wall of the sliding groove 224. A spring piston block 222 is installed at one end of the sliding block 223 and is slidably engaged with the inner wall of the pneumatic cylinder 221.
[0032] The pneumatic cylinder 221 is equipped with a sliding spring piston block 222. Pressing the handle 112 causes the spring piston block 222 to compress towards one side of the pneumatic cylinder 221, resulting in a pressure difference on both sides of the spring piston block 222. This provides resistance to the handle 112, preventing medical staff from pressing the handle 112 too hard and prompting them to reduce their force. This avoids the two gripping heads 213 of the extraction forceps from quickly closing together, thus preventing damage to the tumor during extraction.
[0033] Specifically, the blocking component 31 includes a limiting block 312 fixed inside the connecting base 111 and an inclined block 314 mounted on the sliding block 223. The bottom of the limiting block 312 is movably connected to a spring blocking block 311 sleeved on the air cylinder 221. Throttling holes 315 are opened on both sides of the top outer wall of the air cylinder 221. A sealing rod is installed on the top inner wall of the spring blocking block 311 near the bottom of the limiting block 312. The sealing rod is inserted into the inner wall of the corresponding throttling hole 315.
[0034] Specifically, a connecting rod 313 is mounted on the surface of the spring plug 311, and one end of the connecting rod 313 is attached to the end inclined surface of the inclined block 314.
[0035] When the handle is pressed, the inclined block 314 moves along with the sliding block 223, thereby pushing the connecting rod 313. This causes the connecting rod 313 to move up on the surface of the inclined block 314, lifting the sealing rod and opening the throttling orifice 315. This allows the gas on the side with higher pressure to flow to the other side through the throttling orifice, bringing the gas pressure on both sides closer to equilibrium. This gradually reduces the resistance of the device. After the medical staff encounters resistance when pressing the extraction forceps for the first time, they immediately release the force. At this point, the device resistance is reduced, making it easier for the medical staff to operate the extraction forceps after releasing the force, thus facilitating the clamping of the tumor and subsequent surgical procedures.
[0036] Furthermore, the blocking assembly 32 includes a piston cylinder 321 installed inside the connecting base 111 and an L-shaped rod 323 installed at one end of the sliding block 223. The piston cylinder 321 is provided with a first piston ring 322 and a second piston ring 324. One end of the L-shaped rod 323 passes through the second piston ring 324 and the first piston ring 322 and is located inside the piston cylinder 321. One end of the L-shaped rod 323 is fixedly connected to the first piston ring 322, and one end of the L-shaped rod is slidably connected to the second piston ring.
[0037] When the sliding block 223 moves, it drives the L-shaped rod 323 to move, causing the piston ring 322 to move and compress the gas in the piston cylinder 321, increasing the gas pressure until the gas on the left side of the piston ring 322 pushes the piston ring 324 to move. When the piston ring 322 compresses the gas, the resistance to the piston ring 322 gradually increases. When the gas pushes the piston ring 324 to move, the gas resistance to the piston ring 322 remains stable. This ensures that the medical staff will be blocked by stable gas resistance during the subsequent pressing of the handle 112, effectively preventing the spring block 311 from separating from the throttle orifice 315 and the resistance to the spring piston block 222 from disappearing, thus avoiding a sudden decrease in pressing resistance. This allows the medical staff to accurately control the pressing force of the handle 112.
[0038] The piston cylinder 321 has a mounting hole on one side of its outer wall, and an air nozzle 325 is fixedly connected to the mounting hole.
[0039] As piston ring 2 324 moves, it compresses the gas inside piston cylinder 321 and ejects it through nozzle 325. Since the medical staff's hands need to be held at the position of nozzle 325, the gas ejected from nozzle 325 will come into contact with the medical staff's hands. When piston ring 2 324 moves at a faster speed, it will compress the gas and eject it quickly from nozzle 325. The hand will feel a stronger airflow impact, which will be fed back to the medical staff at the current pressing speed, prompting them to slow down their movements and assisting the medical staff to control the contact between the clamping head 213 and the tumor with a more stable pressing speed.
[0040] The gynecological pelvic tumor extraction forceps provided by the present invention will be further described below with reference to the accompanying drawings and embodiments.
[0041] First, after completing a series of preparatory steps, the extraction forceps can be used to clamp the tumor during tumor retrieval. Medical personnel grasp the forceps via the connecting base 111 and handle 112, then press the handle 112 to move the limiting frame 113 away from the threaded sleeve 211. The limiting frame 113 then contacts the spring push rod 122, pushing it to move and pulling the connecting rod 214, bringing the ends of the two connecting rods 214 closer together. This brings the ends of the two gripping heads 213 closer together, allowing for tumor retrieval. When the handle 112 rotates, it pushes the spring piston block 222, compressing the gas on the left side of the spring piston block 222 and simultaneously creating negative pressure on the right side. This bidirectional increase in resistance to the spring piston block 222's movement to one side provides timely feedback when medical personnel press the handle 112 forcefully, allowing them to perceive excessive pressure and begin to reduce force to avoid damage to the tumor. As the sliding block 223 moves... As the device moves, it causes the blocking component 31 to move. When the inclined block 314 moves, it lifts the connecting rod 313, thereby compressing the limiting block 312 upward. The spring blocking block 311 lifts, and the sealing rod lifts upward, opening the throttling orifice 315 on the left side. Gas moves from the left side of the air cylinder 221 through the two throttling orifices 315 to the right side of the air cylinder 221, removing the obstruction to the gas and allowing the spring piston block 222 to move smoothly. This connects the air chambers on both sides of the air cylinder 221, and the air pressure begins to balance. The resistance on the handle 112 decreases, slowing down the movement speed of the spring piston block 222 and reducing the rotation speed of the handle 112. As the resistance decreases, the medical staff also begin to reduce their force due to the initial resistance, making it easier for them to control the extraction forceps. This allows the clamping head 213 to slowly contact the tumor, effectively preventing the initial pressure of the handle 112 from being too strong and avoiding the clamping head 213 from quickly approaching the tumor, thus preventing the tumor from being crushed and ensuring the integrity of the tumor removal.
