Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 4: the embodiment discloses a removable nucleus pulposus pincers for operation, including the handle and can dismantle the centre gripping subassembly of connecting in the handle, the handle includes that articulated handheld end 1, handheld end two 2, and the tip of handheld end 1, handheld end two 2 is equipped with draw-in groove 11, draw-in groove two 21 respectively.

The clamping assembly comprises a clamp 5 and a sheath 4, the clamp 5 is connected to the end of the sheath 4, a telescopic mandrel 3 used for driving the clamp 5 to move is further arranged in the sheath 4, when the clamping assembly is connected to the handle, the second clamping groove 21 is connected to the mandrel 3, and the first clamping groove 11 is connected to the sheath 4, so that the handle and the sheath 4 are connected and fixed with each other.

The specific connection mode between the first clamping groove 11 and the tube sheath 4 is as follows: the side part of the clamping groove I11 is further provided with an opening thread 12, the tube sheath 4 is further provided with a thread sleeve 42, when the tube sheath 4 is connected to the clamping groove I11, the thread sleeve 42 is connected to the opening thread 12, the section of the opening thread 12 is fan-shaped, the upper end of the opening thread 12 and the upper end of the clamping groove I11 are also in opening arrangement, and when the tube sheath 4 is clamped to the clamping groove I11, the thread sleeve 42 is screwed into the opening thread 12 to fix the tube sheath 4 and the handheld end I1. The sheath 4 is provided with a clamping section 43, and the first clamping groove 11 is connected to the clamping section 43.

Specifically, the mandrel 3 is provided with an annular groove 31, the second clamping groove 21 is connected to the annular groove 31, the second clamping groove 21 can adopt a shifting fork-shaped structure, and the inner distance of the shifting fork is larger than the diameter of the annular groove 31 but smaller than the outer diameter of the mandrel 3.

The concrete mode that the mandrel 3 and the tube sheath 4 drive the clamp 5 to act is as follows: the clamp 5 comprises a fixed clamp 51 and a movable clamp 52 which are hinged with each other, the fixed clamp 51 is connected with the tube sheath 4, and the end part of the mandrel 3 is also hinged with the movable clamp 52. The opening and closing of the clamp 5 are realized by the relative sliding of the mandrel 3 and the tube sheath 4.

In order to facilitate taking, the sheath 4 of the present embodiment is further provided with a handheld section 41 on the outer surface.

During the use, when needs are assembled handle and centre gripping subassembly, go into respectively the joint section 43, annular 31 card to draw-in groove one 11, draw-in groove two 21, draw-in groove one 11 can be the circular arc that the radian is not more than 180 degrees, and draw-in groove two 21 are the structure of similar shift fork. When the connection is completed, the threaded sleeve 42 is screwed into the open thread 12 and tightened.
