SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

The technical problem to be solved by the utility model is as follows: because the anterior handle of traditional nucleus pulposus pincers is movable handle, the rear portion handle is fixed handle, the junction of the inside of anterior handle and rear portion handle is connected through the elastic component, in the in-service use process, anterior handle need press the elastic component ceaselessly and order about the binding clip function, long-term in the past, can lead to the elastic component to take place to warp the bending, the phenomenon of elastic component damage appears even, lead to whole nucleus pulposus pincers can not continue to use again, be difficult to guarantee the self quality of nucleus pulposus pincers, and be the integral type structure between the binding clip of traditional nucleus pulposus pincers and the sheath pole, when the binding clip damages, just can't continue to use again, the waste of other parts has been caused, the problem of the waste of resource has been caused.

(II) technical scheme

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a long service life's medical nucleus pulposus pincers, includes fixed handle, activity handle, connecting axle, connecting rod, sheath pole, binding clip, goes up the pincers and lower pincers, the activity handle with connect through the connecting axle between the fixed handle, the connecting rod passes the inside on the upper portion of fixed handle, and the head of connecting rod with the inside portion of activity handle is connected, the sheath pole with the afterbody of connecting rod is connected, the binding clip sets up the head of sheath pole, it sets up to go up the pincers upper portion of binding clip, lower pincers set up the lower part of binding clip.

Furthermore, the upper part of the fixed handle is of a hollow structure.

Furthermore, a circular half shaft is arranged on the inner side face of the movable handle, and the circular half shaft is movably connected with the connecting shaft.

Further, the upper jaw and the lower jaw have the same internal dimensions.

Furthermore, the clamp head is fixedly connected with the sheath rod in a threaded mode.

(III) advantageous effects

The utility model provides a medical nucleus pulposus clamp with long service life, which has the following beneficial effects: the utility model discloses novel structure, the cost of manufacture is low for nucleus pulposus pincers guarantee nucleus pulposus pincers's life at the in-service use in-process, and make nucleus pulposus pincers can not warp because of long-term the use, guaranteed nucleus pulposus pincers self product quality, and the change can be dismantled to the binding clip, when the binding clip damages, directly change the binding clip can, must not wholly abandon, avoided the waste of resource.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a partially enlarged view of the clamp head according to the present invention;

in the figure: 1-fixed handle, 2-movable handle, 3-connecting shaft, 4-connecting rod, 5-sheath rod, 6-tong head, 7-upper tong clamp and 8-lower tong clamp.

Detailed Description

In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, and are used for convenience of description and simplicity of description only, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present invention.

Referring to fig. 1 and fig. 2, the present invention provides a technical solution: the utility model provides a long service life's medical nucleus pulposus pincers, including fixed handle 1, movable handle 2, connecting axle 3, connecting rod 4, sheath pole 5, binding clip 6, go up tong 7 and lower tong 8, be connected through connecting axle 3 between movable handle 2 and the fixed handle 1, connecting rod 4 passes the inside on fixed handle 1's upper portion, and the head of connecting rod 4 is connected with movable handle 2's inside portion, sheath pole 5 is connected with the afterbody of connecting rod 4, binding clip 6 sets up the head at sheath pole 5, it sets up the upper portion at binding clip 6 to go up tong 7, lower tong 8 sets up the lower part at binding clip 6.
