Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to rotatable foreign body forceps. Background Art

[0002] Endoscopic foreign body removal (EBR) is a treatment method that uses an endoscope to remove foreign bodies from the digestive tract. This procedure is a radical surgical procedure for the digestive tract and can be performed as either emergency or elective EBR. The former is used to remove large, irregular, long, sharp, or toxic foreign bodies, while the latter primarily removes small, smooth foreign bodies. Endoscopic EBR offers advantages such as non-invasiveness, safety, high retrieval rates, and low complication rates.

[0003] Endoscopic digestive tract foreign body removal primarily involves forceps. Currently, a wide variety of forceps are available, but all suffer from the following drawbacks: 1. The forceps cannot be rotated freely; 2. The jaws cannot be opened and closed unilaterally. Currently, these forceps require both jaws to open and close simultaneously, significantly impacting clinical practice. Therefore, a rotatable forceps is necessary to address this technical challenge. Utility Model Content

[0034] As Figures 1-5 shown, the rotatable foreign object forceps of the present utility model include a forceps end 1, a handle end 2, and a connecting line 3;

[0035] The forceps end 1 has a cylindrical structure. A micro camera 4 is inlaid and installed in the middle of the outer end of the forceps end 1. At least two rotating grooves 5 are formed on the outer end of the forceps end 1. Pliers 6 are rotatably installed in the rotating grooves 5. A torsion spring 7 is installed in abutment between the pliers 6 and the rotating grooves 5, and the torsion spring 7 drives the pliers 6 to rotate outwards.

[0036] At least two sliding grooves 8 are formed on the outer side wall of the forceps end 1. Sliders 9 are slidably installed in the sliding grooves 8. The sliding grooves 8 are arranged in one-to-one correspondence with the inner sides of the rotating grooves 5. Protrusions 10 are formed on the inner sides of the pliers 6. A pulling rope 11 is fixedly installed between the protrusions 10 and the sliders 9. When the sliders 9 move in the opposite direction of the rotating grooves 5, the pliers 6 are driven to rotate inwards through the pulling rope 11.

[0037] The connecting line 3 is installed between the forceps end 1 and the handle end 2. The handle end 2 drives the whole forceps end 1 to rotate through the connecting line 3. At least two steel wires 12 are installed in the connecting line 3 with clearance fit. One end of the steel wires 12 is fixedly installed on the sliders 9;

[0038] The principle is: after the clamp end 1 is extended into the digestive tract, since the connecting line 3 is fixed between the clamp end 1 and the handle end 2, the angle of the clamp end 1 can be directly controlled by rotating the handle end 2, and the direction of the clamp 6 can be controlled, which is convenient for aiming at and clamping foreign objects; when aiming at foreign objects, the slider 9 can be moved in the opposite direction of the rotating groove 5 by pulling at least two steel wires 12 at the same time, thereby controlling the clamp 6 to rotate inward, thereby achieving the effect of quickly clamping foreign objects; the opening and closing angle of a single clamp 6 can also be controlled by pulling a single steel wire 12, so that the angle direction of each clamp 6 can be controlled individually, which is convenient for actual use and clinical operation.

[0039] Furthermore: at least two adjustment grooves 13 are formed on the outer side of the handle end 2, and a toggle coil 14 is installed in the adjustment groove 13 for damping rotation, and the other end of the steel wire 12 is wound and installed in the toggle coil 14; the outer end of the steel wire 12 can be wound by the toggle coil 14, and then the steel wire 12 is tightened, and the steel wire 12 and the slider 9 are fixed to each other, so when the toggle coil 14 is wound or unwound, the slider 9 can move in the slide groove 8, thereby realizing separate control of the direction of each pliers 6, which is convenient to use.

[0040] Furthermore: the handle end 2 includes a fixed cylinder 2.1 and a sliding cylinder 2.2, the sliding cylinder 2.2 is slidably fitted on the fixed cylinder 2.1, one end of the connecting line 3 is fixedly installed on the fixed cylinder 2.1, and the adjustment groove 13 is integrally formed and arranged on the outside of the sliding cylinder 2.2; when the sliding cylinder 2.2 slides in the fixed cylinder 2.1, it can drive all the steel wires 12 to tighten or loosen, thereby realizing the simultaneous opening and closing of at least two pliers 6, which is convenient for clamping foreign objects.

[0041] Furthermore: a damping gasket 15 is tightly installed between the side wall of the adjustment groove 13 and the toggle coil 14, and the toggle coil 14 is fitted in the adjustment groove 13 through the damping gasket 15 to damp the rotation; the setting of the damping gasket 15 allows the toggle coil 14 to be automatically locked after rotating in the adjustment groove 13, thereby realizing rapid control of the opening and closing angles of each pliers 6, which is convenient for actual use.

[0042] Furthermore, the outer end of the fixed cylinder 2.1 is formed with a toggle ring 16, and the outer end of the sliding cylinder 2.2 is formed with a push-pull handle 17; the toggle ring 16 and the push-pull handle 17 can be used to allow the sliding cylinder 2.2 to slide inside the fixed cylinder 2.1, making it convenient for at least two pliers 6 to open and close synchronously.

[0043] Furthermore: a limit block 18 is formed on the inner side of the toggle ring 16, and a limit groove 19 is formed on the outer side of the sliding cylinder 2.2. The limit block 18 is slidably installed in the limit groove 19; so that the sliding cylinder 2.2 will not rotate when sliding, thereby ensuring that there will be no angular deviation when the pliers 6 are opened and closed to clamp foreign objects.

[0044] Further: positioning blind holes 20 are formed on both sides inside the rotating groove 5. One end of the pliers 6 close to the rotating groove 5 is fixedly installed with a rotating shaft 21, and both ends of the rotating shaft 21 are respectively rotatably installed in the positioning blind holes 20, which can ensure the stable rotation of the pliers 6 in the rotating groove 5.

[0045] Further: the torsion spring 7 is sleeved and installed on the rotating shaft 21. One end of the torsion spring 7 is fixedly installed at the end of the pliers 6, and the other end of the torsion spring 7 is fixedly installed in the rotating groove 5, which can ensure the stable installation of the torsion spring 7.

[0046] Further: a wire passing groove 22 is formed between the rotating groove 5 and the sliding groove 8. The pulling rope 11 is installed in the wire passing groove 22 with a clearance fit, enabling the pulling rope 11 to be hidden in the plier end 1 and enabling the pulling rope 11 to be more stably fixed between the slider 9 and the convex block 🔗10.

[0047] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the present invention. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention all fall within the protection scope of the technical solution of the present invention.
