Description

Technical Field

[0001] The utility model relates to the technical field of clip appliers, in particular to a reusable clip applier with a limiting function. Background Art

[0002] Conventional clip appliers often lack effective position-limiting features, which can lead to excessive opening of the handle or excessive closing of the clamp tips during use, compromising clamping accuracy and safety. This is particularly true in the medical field, such as surgery, where improper force can cause damage to tissue or blood vessels if the clamps lack effective position-limiting features.

[0003] Although some clip appliers currently available on the market have simple limiting devices, these devices are often complex in structure, inconvenient to use, and prone to malfunction, and cannot well meet the needs of users. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a reusable clip applier with a limiting function to solve the problems in the background art.

[0005] In view of this, the present invention provides a reusable clip applier with a limiting function, comprising:

[0006] A first handle and a second handle that rotate relative to each other via a rotating shaft, wherein the first handle is provided with a rotating limit plate, and the limit plate is used to support one end of the second handle after rotation;

[0007] The pliers head is provided with a limiting structural part at the open end of the pliers head.

[0008] Preferably, a boss is provided on the top of the first handle, and the limiting plate is rotatably connected to the side wall of the boss.

[0009] Preferably, a gasket and a retaining spring are installed on the side wall of the boss, and the gasket is supported on the surface of the limiting plate.

[0010] Preferably, a convex plate is provided on the top of the second handle, and one side of the convex plate is fitted with one end of the limiting plate.

[0011] Preferably, both end surfaces of the pliers opening are provided with grooves for mounting shafts.

[0012] Preferably, the limiting structure is in a ">"-shaped structure, and both ends of the limiting structure are installed in the groove body on the clamp head through installation shafts.

[0013] It can be seen from the above technical solutions that the embodiments of the present invention have the following advantages:

[0014] 1. The present invention provides a reusable clip applier with a limiting function. By providing a rotatable limiting plate on the first handle, which forms a supporting relationship with one end of the second handle, the limiter effectively limits the degree of opening of the handles, and thus the opening of the forceps heads, thereby maintaining the forceps heads in a certain closed state, facilitating subsequent surgical procedures and reducing the risk of potential damage to the operated object. The limiting plate is fixed to the boss via a gasket and a retaining spring, allowing the limiting plate to remain firmly in the desired position during use. It also provides a damping effect during rotation, allowing the user to quickly adjust the limiting position according to actual needs, thereby improving operational convenience.

[0015] 2. The utility model is a reusable clamp with a limiting function. A limiting structure is provided at the open end of the clamp head. Its unique ">"-shaped design not only ensures the stability of the clamp head when closed, but also effectively prevents the self-locking phenomenon caused by excessive force, ensuring precise control during use.

[0016] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0026] A reusable clip applier with a position limiting function according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Example

[0028] For easier understanding, see Figures 1 to 6 The present invention provides an embodiment of a reusable clip applier with a limiting function, comprising:

[0029] A first handle 1 and a second handle 2 are rotated relative to each other via a rotating shaft, wherein a rotating limit plate 3 is provided on the first handle 1, and the limit plate 3 is used to support one end of the second handle 2 after rotation;

[0030] The pliers head 5 has an opening end provided with a limiting structure 51 .

[0031] It should be noted that the first handle 1 and the second handle 2 are connected by a rotating shaft, allowing them to rotate relative to each other. A boss 11 is provided on the top of the first handle 1, and a rotatable stop plate 3 is provided on the side wall of the boss 11. When the stop plate 3 rotates to a certain position, it can support one end of the second handle 2 to prevent the handle from being excessively opened.

[0032] In an optional embodiment, a boss 11 is provided on the top of the first handle 1, and the limiting plate 3 is rotatably connected to the side wall of the boss 11. A gasket 4 and a retaining spring 6 are installed on the side wall of the boss 11, and the gasket 4 is supported on the surface of the limiting plate 3.

[0033] It should be noted that the limit plate 3 is rotatably connected to the side wall of the boss 11. To ensure smooth rotation and securement of the limit plate 3 in place, a gasket 4 and a retaining spring 6 are mounted on the side wall of the boss 11. The gasket 4 supports the limit plate 3, while the retaining spring 6 defines its position, maintaining stability during use. The gasket 4 and retaining spring 6 secure the limit plate 3, creating a damped feel during rotation, requiring manual movement. In its natural state, the limit plate 3 remains stationary.

[0034] In an optional embodiment, a convex plate 21 is provided on the top of the second handle 2 , and one side of the convex plate 21 is fitted with one end of the limiting plate 3 .

[0035] It should be noted that a convex plate 21 is provided on the top of the second handle 2, and one side of the convex plate 21 fits with one end of the limit plate 3. When the limit plate 3 rotates to a proper position and contacts the convex plate 21, a limit is formed to prevent the handle from further opening.

[0036] In an optional embodiment, both end surfaces of the opening of the pliers head 5 are provided with slots for mounting shafts. The limiting structure 51 is in a ">" shape, and both ends of the limiting structure 51 are mounted in the slots on the pliers head 5 via mounting shafts.

[0037] It should be noted that a ">"-shaped limiting structure 51 is provided at the open end of the clamp head 5. The two ends of the limiting structure 51 are mounted via mounting shafts within slots formed on the two end surfaces of the clamp head 5. The limiting structure 51 ensures the stability and safety of the clamp head 5 during use, preventing the clamp from locking due to excessive force during operation.

[0038] Working principle: When it is necessary to use the clamping forceps for clamping operations, first adjust the angle of the limit plate 3 as needed so that it can be rotated to the appropriate limit position. After the adjustment is completed, the limit plate 3 is fixed in this position by the retaining spring 6, which effectively limits the degree of opening of the first handle 1 and the second handle 2, and then limits the opening of the pliers head 5, so that the pliers head 5 can be in a certain closed state, which is convenient for subsequent surgical operations and reduces the potential risk of damage to the operation object. After the clamping is completed, the limit can be released by rotating the limit plate 3 in the opposite direction to restore the handle to a free state. A limit structure 51 is provided at the open end of the pliers head 5, which has a shape similar to ">" and is fixed in the groove body on the two end faces of the opening of the pliers head 5 by the mounting shaft. This limit structure 51 plays a role in preventing the pliers head 5 from being over-closed due to excessive external force in actual operation. It is particularly suitable for scenarios that require fine control of force, such as preventing blood vessels from being closed due to excessive compression during surgery.

[0039] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
