Detailed Description

The technology in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1-3, the present embodiment provides a double-joint bar-rotating forceps,

comprises a first forceps handle 1, a second forceps handle 2, a first forceps head 3 and a second forceps head 4;

the first forceps handle 1 and the second forceps handle 2 are hinged at a position close to the handle part at the front end, the front end of the first forceps handle 1 is hinged with the tail end of the first forceps head 3, the front end of the second forceps handle 2 is hinged with the tail end of the second forceps head 4, and the first forceps head 3 is hinged with the second forceps head 4 at the middle section;

be equipped with interlock district 8 between first binding clip 3 and the second binding clip 4, be equipped with interlock tooth 801 in the interlock district 8, it has rotation tooth condition 5 to articulate through articulated seat on the first pincers handle 1, it includes dwang 510 and rack portion 520 to rotate tooth condition 5, be equipped with perpendicularly on the second pincers handle 2 and can match the rack spare 6 of meshing with rack portion 520, be equipped with between first pincers handle 1 and the second pincers handle 2 and be close to laminating and the flexure strip 7 of reverse action along first pincers handle 1 and second pincers handle 2, flexure strip 7 includes bearing part 701 and buckling part 702, buckling part 702 sets up the terminal position of laminating contact dwang 510 in first pincers handle 1 one side.

In this embodiment, the end of the rotating rod 510 is provided with a sinking groove 511, the size of the sinking groove 511 matches the size of the end of the buckling part 702, and the sinking groove 511 aligns the end of the buckling part 702 to prevent the buckling part 702 from deviating and separating from the rotating rod 510.

In this embodiment, the engaging portion 702 is an arc-shaped piece whose outer side is close to the end of the first handle 1, so that the engaging portion 702 contacts with the rotating rod 510 in the inner region of the handle, which is also beneficial to the elastic force storage of the engaging portion 702.

In this embodiment, the engagement area 8 is circular or oval, the engagement teeth 801 are uniformly distributed on the facing surfaces of the first jaw 3 and the second jaw 4, and the engagement teeth 801 engage with the corresponding bar in the engagement area 8.

In this embodiment, the rack portion 520 and the rack member 6 are provided with helical teeth matching with each other, the helical teeth are beneficial to fastening and clamping the rack portion 520 and the rack member 6 when they are engaged, and are convenient for dislocation and separation of the two, so that the engaging teeth 801 release the bar body, and the engaging region 8 is disengaged.

In this embodiment, the tail ends of the first forceps handle 1 and the second forceps handle 2 are provided with stripe-shaped silica gel grooves, so that the friction force is increased, and the hand feeling of the surgical staff is improved.

The working principle of the utility model is as follows, when a bar body is occluded, a first plier handle 1 is close to and attached to a second plier handle 2, an elastic sheet 7 is compressed and contracted, a rotating tooth condition 5 is propped against a rotating rod 510 under the action of a buckling part 702, a sinking groove 511 is matched and attached with the end part of the buckling part 702, a rack part 520 is parallel to and matched and engaged with a rack part 6, and the reverse tension of the elastic sheet 7 enables the rack part 520 to be locked with the rack part 6, so that the first plier handle 1 is stably connected with the second plier handle 2, meanwhile, the movement of the first plier handle 1 and the second plier handle 2 drives a first plier head 3 to be close to a second plier head 4, and the corresponding bar body is occluded in an occlusion area 8; when the occlusion area 8 is to be opened, the first forceps handle 1 and the second forceps handle 2 are further close to each other and the rack portion 520 and the rack member 6 are dislocated and separated, the elastic piece 7 is reset, the buckling portion 702 is not attached to the rotating rod 510 any more, the first forceps handle 1 and the second forceps handle 2 are opened under the action of the elastic piece 7, and the rotating rod forceps are moved to enable the rod body to exit the occlusion area 8.

Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
