In a preferred embodiment of the present invention, the first toggle part 5 and the second toggle part 8 are both in the shape of a circular sheet, and the first handle 4 and the second handle 7 are both in the shape of a rod.

The disc-shaped structure can move the joint capsule tissue to one side after the joint capsule tissue is stripped so as to be convenient for the operation of the next operation, and the disc-shaped structure can also play a role of a shovel, namely, the stripped joint capsule tissue is shoveled.

It should be noted that the shape of the first toggle portion 5 may be a disc shape, but it is not limited to a disc shape, and it may also be other shapes, such as a column shape, etc., as long as it can peel off the joint capsule tissue.

The rod-shaped first handle 4 can be conveniently held and is convenient to use.

It should be noted that the shape of the first handle 4 may be a rod shape, which is not limited to a rod shape, but may also be other shapes, for example, a plate-shaped structure may also be used, which only needs to be able to drive the first toggle portion 5 to move through the first handle 4, so as to achieve the function of peeling the joint capsule tissue.

In this embodiment, the first handle 4 and the first toggle part 5 form a structure of the aforementioned joint capsule tissue dissector, the second handle 7 and the second toggle part 8 also form a structure of the aforementioned joint capsule tissue dissector, and after the first handle 4 and the second handle 7 are rotatably connected by the rotating shaft, the first toggle part 5 and the second toggle part 8 can be attached to each other, thereby forming a pincer-shaped structure.

Preferably, the first toggle part 5 and the second toggle part 8 are completely attached to ensure the accuracy of the use when the forceps are used as a pulling forceps.

When the clamp-type structure is used, the joint capsule tissue can be peeled off through the attached structure, and the clamp of the joint capsule tissue can be realized through the clamp function, or the function equivalent to a vascular clamp can be realized.

Preferably, the included angle formed between the first handle 4 and the first toggle part 5 is 0 °, 15 ° or 30 °.

It should be noted that the included angle formed between the first handle 4 and the first toggle portion 5 may be some angles, but it is not limited to these angles, and it may also be other angles, such as 20 ° or the like, as long as it can facilitate the peeling of the joint capsule tissue.

In this embodiment, in the same way, a certain angle is provided between the second handle and the second stirring part, and the angle between the first handle and the first stirring part is the same as the angle between the second handle and the second stirring part, so that the first stirring part and the second stirring part can be completely attached.

In a preferred embodiment, as shown in fig. 7, a first clamping tooth 6 is arranged on one side of the first toggle part 5 close to the second toggle part 8, a second clamping tooth 10 is arranged on one side of the second toggle part 8 close to the first toggle part 5, and the first clamping tooth 6 is engaged with the second clamping tooth 10.

Specifically, in this embodiment, the shapes of the first clamping tooth 6 on the first toggle part 5 and the second clamping tooth 10 on the second toggle part 8 are both arc-shaped teeth, and when the joint capsule tissue is clamped and pulled out through the clamp functions of the first toggle part 5 and the second toggle part 8, the joint capsule tissue is not subjected to shear stress, so that the joint capsule tissue is not clamped, and the efficiency of taking out the joint capsule tissue is improved.

Specifically, in the present embodiment, the number of the first clamping teeth 6 is plural, and the number of the second clamping teeth 10 is also plural.

More specifically, in the present embodiment, the number of the first clamping teeth 6 is the same as the number of the second clamping teeth 10, or the difference between the number of the first clamping teeth 6 and the number of the second clamping teeth 10 is 1, so that the first toggle part 5 and the second toggle part 8 can be completely attached to each other, and the condition that the clamping teeth are too many to be attached to each other is avoided, thereby ensuring the use efficiency of the tissue forceps of the present invention.

Preferably, the end of the first handle 4 away from the first toggle part 5 is provided with a handle 9, and the end of the second handle 7 away from the second toggle part 8 is provided with a handle 9.

In this embodiment, after the first handle 4 and the second handle 7 jointly form the pincer-shaped structure, the handle 9 is arranged at the end of the first handle 4 far away from the first toggle part 5 and the end of the second handle 7 far away from the second toggle part 8, and through the arrangement of the handle 9, the first handle 4 and the second handle 7 can be conveniently rotated, so as to realize the functions of opening and clamping the pincer-pulling pliers.

Specifically, in the present embodiment, as shown in fig. 4 and 6, the handle 9 is ring-shaped.

More specifically, annular handle 9 can make things convenient for the finger to insert the back, drives handle 9 and removes, and then drives first handle 4 and second handle 7 and rotate, realizes the function of concrete pulling out pincers.

It should be noted that the shape of the handle 9 can be a ring shape, but it is not limited to a ring shape, and it can be other shapes, such as a slot structure, which only needs to drive the first handle 4 and the second handle 7 to rotate, so as to open and close the tissue forceps.

Preferably, the first handle 4 is provided with a bending portion 11, as shown in fig. 8, two ends of the bending portion 11 are respectively connected with the first handle 4 and the first toggle portion 5.

Set up bending portion 11 on first handle 4 for certain angle has been had between first stirring portion 5 and the first handle 4, when peeling off joint capsule tissue, can more facilitate the use.

Specifically, in this embodiment, the setting of the portion of bending 11, it is excessive with having the arc between first handle 4, and then can avoid when using, the junction between the portion of bending 11 and the first handle 4 causes the damage to human tissue.

In the embodiment, the length of the part of the first handle between the rotating shaft and the first toggle part is 5cm-15cm, the length of the part of the second handle between the rotating shaft and the second toggle part is 5cm-15cm, wherein the lengths of the first handle and the second handle are the same, and the length of the part of the first handle between the rotating shaft and the first toggle part is the same as the length of the part of the second handle between the rotating shaft and the second toggle part.

The invention has the beneficial effects that:

the first toggle part 5 is driven to move by the first handle 4, and then the first blade end 3 on the first toggle part 5 is utilized to strip joint tissues, especially soft tissues around the joint capsule, so that the next operation around the joint capsule is facilitated.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
