Description

Technical Field

[0001] This invention relates to the technical field of tissue forceps, and more particularly to a reusable, quick-release tissue forceps. Background Technology

[0002] Tissue forceps are instruments used in surgery to grasp, fix, or lift human tissues. Currently, tissue forceps are primarily made of all-steel and are non-removable, which presents drawbacks such as inconvenience in sterilization and heavy weight. The non-removable design also limits the instrument's functional expandability, making it impossible to change to different toothed jaws, thus increasing usage costs. Later designs adopted a modular approach, but existing detachable tissue forceps mostly use threaded connections. These threaded connections can loosen during use, and under high-frequency vibrations during surgery, micro-displacement can occur, leading to a decrease in clamping force. Furthermore, existing structures struggle to balance ease of assembly / disassembly with clamping stability.

[0003] Therefore, it is necessary to provide a reusable quick-release tissue forceps that can achieve both rapid disassembly and stable disassembly. Summary of the Invention

[0004] The purpose of this invention is to provide a reusable, quick-release tissue forceps to solve the problems mentioned in the background art.

[0006] The second fixing component includes a circular block, a movable rod is provided inside the circular block, grooves are provided on both sides of the movable rod, and a rolling ball is provided inside the groove. Circular grooves are provided on both sides of the circular block, the rolling ball and the circular groove are corresponding to each other, the annular groove and the rolling ball are corresponding to each other, and a movable component is provided on one side of the circular block.

[0007] A clamp head is attached to one side of the circular block.

[0008] In one embodiment, the moving component includes a moving block slidably connected inside a circular block, the moving block and the circular block being fixedly connected, a first spring being sleeved on the outer side of one side of the circular block, the first spring being fixedly connected to the moving block, strip grooves being formed on both sides of the circular block, a sliding piece being disposed inside the strip groove, the sliding piece being slidably connected to the circular block, and the sliding piece being fixedly connected to the moving block.

[0009] In one embodiment, the first fixing component includes an insert block and a circular block that are fixedly connected. Both sides of the insert block are fixedly connected to protrusions, and the insert block and protrusions correspond to the slots. A rotating component is connected inside the mounting sleeve, and a positioning rod is fixedly connected to one side of the circular block. The positioning rod corresponds to the rotating component.

[0010] In one embodiment, the rotating assembly includes a ratchet, which is rotatably connected inside the mounting sleeve. The ratchet has a slot inside, and the positioning rod corresponds to the slot. A locking assembly is provided on one side of the ratchet.

[0011] In one embodiment, the locking assembly includes a pawl, which corresponds to a ratchet. A through groove is provided on one side of the mounting sleeve, through which the pawl passes. A crossbar is fixedly connected to the middle of the pawl, and the crossbar and the through groove are rotatably connected. A second spring is fixedly connected to the side of the pawl away from the ratchet, and the second spring and the mounting sleeve are fixedly connected.

[0012] In one embodiment, the locking assembly includes a second ratchet located at the junction of two pliers. The second ratchet is fixedly connected to one of the pliers, while the other pliers is rotatably connected to the second ratchet. A second pawl is located on one side of the second ratchet.

[0013] In one embodiment, a circular sleeve is fixedly connected to one side of another pliers handle, the second ratchet is located inside the circular sleeve, a square groove is provided on one side of the circular sleeve, the second pawl passes through the square groove and corresponds to the second ratchet, the middle part of the second pawl is rotatably connected to the other pliers handle, and a third spring is fixedly connected to the end of the second pawl away from the second ratchet, the third spring and the circular sleeve are fixedly connected.

[0014] In one embodiment, a friction surface is provided on one side of the pliers head.

[0015] In one embodiment, a limiting flange is provided at the opening of the circular groove to restrict the rolling ball from falling out of the circular groove.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] 1. This invention comprises a movable component, a first fixed component, and a second fixed component. When the forceps head is inserted, the movable component, i.e., by pushing the slider, moves the movable block, allowing the ball to partially enter the groove without restriction. After insertion, the spring rebounds, returning the movable component to its initial position, and the ball is again restricted and locked inside the annular groove. At this point, rotation causes the insert block inside the first fixed component to rotate and abut against the fixed block. Simultaneously, the ratchet rotates, and the pawl prevents it from rotating in the opposite direction, thus completing a triple locking mechanism to ensure stability during operation. Disassembly only requires unlocking the ratchet and then rotating and operating the movable component, without the need for special tools. This simplifies operation, saves manpower, facilitates forceps head replacement, reduces costs, and offers high overall adaptability. Disassembly requires a two-step operation: unlocking the first fixed component, pulling the movable component, and removing the forceps head, avoiding the risk of accidental loosening during surgery.

[0018] 2. This invention features a locking component. Under the action of the third spring, the pawl always adheres to the ratchet, allowing only unidirectional rotation. After clamping, the two clamp handles, which were originally joined together, become open handles. At this point, they will not open because the rotation is restricted. This restricts the clamping angle, preventing further clamping and ensuring precision and stability during surgery. Attached Figure Description

[0034] The following disclosure provides many different embodiments or examples for implementing different structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0035] Please see Figure 1-10 The present invention provides a technical solution: a reusable quick-release tissue forceps, comprising two forceps handles 1, a locking component provided at the junction of the two forceps handles 1, an installation sleeve 101 connected to one side of the forceps handle 1, a slot 104 provided on the inner top of the installation sleeve 101, a first fixing component corresponding to the inside of the slot 104, and an annular groove 107 provided on the inner side of the installation sleeve 101, a second fixing component corresponding to the inside of the annular groove 107.

[0036] The second fixing component includes a circular block 201, a movable rod 202 is provided inside the circular block 201, grooves 203 are provided on both sides of the movable rod 202, a ball 204 is provided inside the groove 203, circular slots are provided on both sides of the circular block 201, the ball 204 corresponds to the circular slots, the annular groove 107 corresponds to the ball 204, and a movable component is provided on one side of the circular block 201.

[0037] A clamp head 2 is connected to one side of the round block 201.

[0038] Specifically, the two clamp handles 1 form a scissor-like structure, with a locking component at the junction to limit the opening size of the two clamp handles 1. A cylindrical mounting sleeve 101 is welded to the front end of each clamp handle 1. A groove 104 is machined into the top of the inner wall of the mounting sleeve 101, and an annular groove 107 is machined around the middle of the inner wall. The clamp head 2 is fixedly connected to the circular block 201, which is a cylinder with a diameter matching the inner diameter of the mounting sleeve 101. Grooves 203 are symmetrically machined on both sides of the moving rod 202. A ball 204 corresponds to each groove 203. Initially, the ball 204 is not inside the groove 203, but is pressed against the outside of the circular block 201. During assembly, insert the round block 201 into the mounting sleeve 101. First, pull the moving component. As the moving component moves, the ball 204, no longer under pressure, inserts into the mounting sleeve 101. Then, it is squeezed back by the inner wall of the mounting sleeve 101, partially moving into the groove 203. When it moves to the annular groove 107, the moving component returns to its original position. Under pressure, the ball 204 partially enters the annular groove 107, locking itself in place. The insert block 206 at the top of the round block 201 is fixed to the slot 104. At this point, rotate the first fixing component to complete a secondary locking. During disassembly, first unlock the first fixing component, then operate the moving component. Pull the moving rod 202, which passes through the groove 203 and returns to the vicinity of the ball 204. After disengaging from the annular groove 107, the pliers head 2 can be pulled out. The cooperation of the ball 204, groove 203, and annular groove 107 enables quick assembly and disassembly, replacing the traditional threaded connection. The first fixing component is then used to complete the secondary locking, ensuring overall stability. Pressing and rotating, followed by pulling the moving component, is required to complete the disassembly. While not difficult, it requires two operations to avoid the risk of accidental opening and ensure safety during operation.

[0039] The movable component includes a movable block 209, which is slidably connected inside the circular block 201. The movable block 209 and the circular block 201 are fixedly connected. A first spring 205 is sleeved on the outer side of one side of the circular block 201. The first spring 205 and the movable block 209 are fixedly connected. Strip grooves 211 are opened on both sides of the circular block 201. A slider 210 is provided inside the strip groove 211. The slider 210 and the circular block 201 are slidably connected. The slider 210 and the movable block 209 are fixedly connected.

[0040] Specifically, when the relevant personnel prepare to install the pliers head 2, they first need to insert the round block 201 into the installation sleeve 101. Before insertion, the ball 204 of the round block 201 protrudes outward. Therefore, the relevant personnel need to push the slider 210, which moves the internally fixedly connected moving block 209. The slider 210 moves towards the ball 204, and the moving block 209 moves towards the ball 204. During the movement, the first spring 205 is compressed, resulting in a rebound force. During the movement, the groove 203 moves to the side of the ball 204. Originally, one side of the moving rod 202 was against the ball 204. 04. Once the groove 203 is in place, it no longer presses against the ball 204. During insertion, under pressure, the ball 204 will temporarily partially enter the groove 203, thus completing the insertion. After insertion, release the slider 210. Under the rebound force of the first spring 205, the slider 210 will return to its original position, the groove 203 will move away from the ball 204, and the moving rod 202 will press against the ball 204 again, causing part of the ball 204 to fall into the annular groove 107, thus completing the fixation. One end of the moving rod 202 has a smaller diameter, so it can press against the ball 204 without applying too much force. The other end of the moving rod 202 is in contact with the inside of the circular block 201, slidingly connected, facilitating smooth pressing and movement. By setting up the moving component, locking and unlocking can be completed by pushing the slider 210, which is simple to operate, requires no auxiliary tools, and saves manpower.

[0041] The first fixing component includes a plug 206, which is fixedly connected to a round block 201. Both sides of the plug 206 are fixedly connected to protrusions 208. The plug 206 and protrusions 208 correspond to the slot 104. The mounting sleeve 101 is internally connected to a rotating component. One side of the round block 201 is fixedly connected to a positioning rod 207, which corresponds to the rotating component.

[0042] Specifically, after inserting the round block 201 into the mounting sleeve 101, the insert block 206 at one end is inserted into the slot 104. Rotating the round block 201 causes the bottom insert block 206 to rotate as well, causing the protrusion 208 to rotate within the slot 104. The slot 104 has a central circular groove corresponding to the insert block 206, and rectangular grooves on both sides corresponding to the protrusion 208. It also has internal slots corresponding to the rotation path of the protrusion 208, allowing it to rotate. After a while, the protrusion 208 is stopped, preventing the insert block 206 from falling out, thus completing the insertion and fixation. Simultaneously, the positioning rod 207 is inserted into the rotating assembly. As the round block 201 rotates, the rotating assembly rotates along with it, creating a secondary lock for enhanced stability. The first fixing component allows the tissue forceps to be fixed simply by rotating after insertion, simplifying the operation. Combined with the second fixing component, the overall system is very stable, and disassembly is also easy.

[0043] The rotating assembly includes a ratchet 102, which is rotatably connected inside the mounting sleeve 101. The ratchet 102 has a slot 103 inside, and the positioning rod 207 corresponds to the slot 103. A locking assembly is provided on one side of the ratchet 102.

[0044] Specifically, when the round block 201 is inserted into the mounting sleeve 101, the insert block 206 is inserted into the slot 104. At this time, the positioning rod 207 is also inserted into the slot 103. In this way, the ratchet 102 is essentially integrated with the round block 201. When the round block 201 rotates, the ratchet 102 will also rotate. When the round block 201 stops rotating, the ratchet 102 will also stop rotating. Under the constraint of the locking assembly, the ratchet 102 will not reverse, thus completing the fixation. This achieves triple fixation of the pliers head 2, preventing accidental loosening by relevant personnel. The overall system is more stable and also easier to disassemble.

[0045] The locking assembly includes a pawl 105, which corresponds to a ratchet 102. A through slot is provided on one side of the mounting sleeve 101, through which the pawl 105 passes. A crossbar is fixedly connected to the middle of the pawl 105, and the crossbar and the through slot are rotatably connected. A second spring 106 is fixedly connected to the side of the pawl 105 away from the ratchet 102, and the second spring 106 and the mounting sleeve 101 are fixedly connected.

[0046] Specifically, under normal, uninterrupted conditions, because the second spring 106 has a certain elasticity, it will push one end of the pawl 105 upwards, so that the other end of the pawl 105 always adheres to the ratchet 102. This restricts the ratchet 102 to rotate only in one direction and prevents it from rotating in the opposite direction. When disassembly is required, simply press the pawl 105 at one end of the second spring 106 downwards and lift the other end. This removes the pawl 105 from restricting the ratchet 102. Personnel can then rotate the circular block 201 in the opposite direction, causing the ratchet 102 to rotate in the opposite direction until the insert block 206 is no longer stuck inside the slot 104. The moving component also moves downwards, releasing the lock, and the entire assembly can then be removed for disassembly. By incorporating a ratchet and pawl, restricting rotation to only one direction, a third layer of locking is achieved, resulting in high overall stability.

[0047] The locking assembly includes a second ratchet 301, which is located at the junction of two clamp handles 1. The second ratchet 301 is fixedly connected to one of the clamp handles 1, while the other clamp handle 1 is rotatably connected to the second ratchet 301. A second pawl 302 is located on one side of the second ratchet 301.

[0048] Specifically, ratchet 2 301 is located at the junction of the two clamp handles 1, fixedly connected to one of the handles 1, and rotatably connected to the other handle 1. Pad 2 302 cooperates with ratchet 2 301 to restrict its unidirectional rotation. When the personnel use the tissue forceps, they rotate the two handles 1 closer together, in the direction of ratchet 2 301's rotation. Pad 2 302 does not restrict this rotation. After clamping, the personnel no longer press the tissue forceps, and further clamping is no longer needed. The hands are in an open state, and at this point, pad 2 302 restricts rotation, ensuring stability. The clamping force is fixed at that level, which is also stable. After clamping, no further clamping force is needed; the force is applied in the opposite direction, ensuring clamping strength and overall stability.

[0049] A circular sleeve 3 is fixedly connected to one side of another pliers handle 1. A ratchet wheel 301 is located inside the circular sleeve 3. A square groove is provided on one side of the circular sleeve 3. A pawl 302 passes through the square groove and corresponds to the ratchet wheel 301. The middle part of the pawl 302 is rotatably connected to the other pliers handle 1. A third spring 303 is fixedly connected to the end of the pawl 302 away from the ratchet wheel 301. The third spring 303 and the circular sleeve 3 are fixedly connected.

[0050] Specifically, the circular sleeve 3 supports the third spring 303. The circular sleeve 3 and the pliers 1 are fixedly connected, essentially forming a single unit. Under the elastic force of the third spring 303, the second pawl 302 always fits against the second ratchet 301, thus restricting reverse rotation. If rotation is required, press the second pawl 302 on one side of the third spring 303, and the second pawl 302 on the other end can move upwards, thus removing the overall restriction.

[0051] A friction surface is provided on one side of the pliers head 2.

[0052] Specifically, this way it won't easily fall off when held in place.

[0053] A limiting flange is provided at the opening of the circular groove to prevent the rolling ball 204 from falling out of the groove.

[0054] Specifically, this restricts the ball 204 inside the groove, allowing it to move partially but preventing it from falling out.
