Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tissue forceps, in particular to a tissue forceps with replaceable forceps heads. Background Technique
[0002] Tissue forceps are also called rat-tooth forceps. The squeezing of tissues is lighter than that of blood vessel forceps. Therefore, they are generally used to hold soft tissues and are not easy to slip off. For example, they hold and pull the diseased part to be excised to facilitate the operation, and clamp the subcutaneous tissue of the gauze pad and the incision edge to avoid the tissues in the incision being contaminated.
[0003] With different usage environments, tissue forceps with different forceps head sizes are also needed. Generally, the number of tissue forceps in each group with different forceps head sizes is fixed. After the tissue forceps of the required model size are used up, other groups of tissue forceps need to be taken, resulting in a certain waste in the overall use. Therefore, a tissue forceps with replaceable forceps heads is needed, which can replace the forceps heads to supplement the tissue forceps of the required model size. Content of the Utility Model
[0004] The purpose of the utility model is to provide a tissue forceps with replaceable forceps heads to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: a tissue forceps with replaceable forceps heads, including a tissue forceps. One end of the tissue forceps is provided with two moving cavities. Two moving holes are penetrated through the cavity walls of the two moving cavities. A moving block is slidably connected in each of the two moving cavities. A first threaded rod is fixedly connected to each of the two moving blocks at positions corresponding to the two moving holes. One end of each of the two first threaded rods away from the moving block penetrates and extends outside the tissue forceps. Two forceps heads are arranged on the outside of one end of the tissue forceps. A threaded groove is opened on one side of each of the two forceps heads close to the tissue forceps. The two first threaded rods are respectively threadedly connected to the two threaded grooves. A threaded hole is penetrated through the cavity wall of each of the two moving cavities. A second threaded rod is threadedly connected in each of the two threaded holes.
[0006] Preferably, one end of each of the two second threaded rods away from the moving block penetrates and extends outside the tissue forceps, and two rotating grooves are opened at one end of each of the two second threaded rods located outside the tissue forceps.
[0007] Preferably, one side of each of the two moving blocks close to the second threaded rod is arranged in an inclined shape, and the two second threaded rods respectively abut against the inclined surfaces of the two moving blocks.
[0008] Preferably, two handles are fixedly connected to the outside of the end of the tissue forceps away from the forceps head.
[0009] Preferably, the two first threaded rods are respectively slidably connected in the two moving holes.
[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: when in use, the pliers head is threadedly connected to the first threaded rod through the thread groove, and the two pliers heads are adjusted to opposite positions. Then, the second threaded rod can be rotated to move into the moving cavity, and the moving block is pushed to descend together with the first threaded rod by abutting against the inclined surface of the moving block. The first threaded rod drives the pliers head to descend until it abuts against the tissue forceps, thereby preventing the tissue forceps from being affected by rotation during the fixation process and keeping the pliers head parallel for convenient use.

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0016] Please refer to Figures 1-3 , the present utility model provides a technical solution: a tissue forceps with replaceable pliers heads, including a tissue forceps 1. Two moving cavities 2 are opened at one end of the tissue forceps 1. Two moving holes 3 are penetrated through the cavity walls of the two moving cavities 2. A moving block 4 is slidably connected in each of the two moving cavities 3. A first threaded rod 5 is fixedly connected to each of the two moving blocks 4 corresponding to the positions of the two moving holes 3. One end of each of the two first threaded rods 5 far from the moving block 4 penetrates and extends outside the tissue forceps 1. Two pliers heads 6 are arranged on the outer side of one end of the tissue forceps 1. A thread groove 7 is opened on one side of each of the two pliers heads 6 close to the tissue forceps 1. The two first threaded rods 5 are respectively threadedly connected to the two thread grooves 7. A threaded hole 8 is penetrated through the cavity wall of each of the two moving cavities 2. A second threaded rod 9 is threadedly connected in each of the two threaded holes 8.
[0017] Wherein, one end of each of the two second threaded rods 9 far from the moving block 4 penetrates and extends outside the tissue forceps 1, and two rotation grooves 10 are formed at one end of each of the two second threaded rods 9 located outside the tissue forceps 1, and the second threaded rods 9 can be rotated through the rotation grooves 10.
[0018] Wherein, one side of each of the two moving blocks 4 close to the second threaded rod 9 is inclined, and the two second threaded rods 9 respectively abut against the inclined surfaces of the two moving blocks 4. When the second threaded rod 9 moves into the moving cavity 2, the moving block 4 will be pushed to descend by the second threaded rod 9 abutting against the inclined surfaces of the two moving blocks 4.
[0019] Wherein, two handles 11 are fixedly connected to the outer side of one end of the tissue forceps 1 far from the clamp head 6, and the tissue forceps 1 can be held by the handles 11.
[0020] Wherein, the two first threaded rods 5 are respectively slidably connected in the two moving holes 3, so that the two first threaded rods 5 vertically lift and lower in the moving holes 3.
[0021] Specifically, when using the present utility model, first, the clamp head 6 is threadedly connected to the first threaded rod 5 through the thread groove 7 until the first threaded rod 5 abuts against the bottom of the thread groove 7, and then the clamp head 7 is rotated to adjust it so that the two clamp heads 6 are arranged oppositely. At this time, the second threaded rod 9 can be rotated through the rotation groove 10, and the second threaded rod 9 will move into the moving cavity 2 in the threaded hole 8 and abut against the inclined surfaces of the two moving blocks 4 to push the moving block 4 to descend, and the moving block 4 will drive the first threaded rod 5 and the clamp head 6 to descend until they abut against the tissue forceps 1, so that the two clamp heads 6 are arranged in parallel and will not rotate easily, thus avoiding affecting the level and fixation of the clamp head 6, and the clamp head 6 can be replaced to facilitate adjustment and use according to needs during the operation.
[0022] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model, and the scope of the present utility model is defined by the appended claims and their equivalents.
