second bits

2, 3 are in a self-locking state of relative rest.

In order to ensure that first binding clip 2 and second binding clip 3 can keep the self-locking at the clamping state that keeps silent and be close to the utility model discloses in the further optional embodiment, be equipped with on the butt face 4032 and be used for carrying out the draw-in groove of rigidity to first binding clip 2 or second binding clip 3, further, the butt end of first binding clip 2 and second binding clip 3 is equipped with the spacing arch of matcing with above-mentioned draw-in groove. The arrangement of the structure is beneficial to realizing that self-locking can occur between the abutting ends of the first binding clip 2 and the second binding clip 3 and the cam 403 when the cam 403 rotates to the maximum angle, so that the clamping force of the jaws and the clamping stability are ensured, and the repeated positioning precision is high.

In an alternative embodiment of the present invention, in order to improve the tightness of the overall structure of the clamp 8 for puncturing, it is preferable that a height difference exists between the torsion spring 401 and the cam 403, so that the torsion spring 401 and the cam 403 are respectively arranged in a connection relationship with the first binding clip 2 and the second binding clip 3 without interfering with each other.

In the optional embodiment of the present invention, the first binding clip 2 and the second binding clip 3 are provided with a limiting groove for accommodating the cam 403, so as to ensure that the first binding clip 2 and the second binding clip 3 can only switch positions between the corresponding abutment surface 4032 and the positioning notch 4031 to realize clamping and releasing of the jaws. Preferably, the limiting groove is a notch with a semicircular structure, and the structure limits the rotation range of the cam 403 around the second pin shaft 404 and the rotation position (from ON to OFF) of the knob 6, so that the operation is simpler and more convenient.

In the utility model discloses optional embodiment, in order to facilitate rotating cam 403, a knob 6 and second round pin axle 40 connection for anchor clamps 8 of puncture, rotate knob 6 and rotate in order to drive cam 403 through second round pin axle 404, thereby realize the removal of the butt end of first binding clip 2 and second binding clip 3 on the outer peripheral face of cam 403, and then realize the relative or removal in opposite directions of the exposed core of first binding clip 2 and second binding clip, in order to carry out centre gripping or release to puncture sleeve 5.

In order to protect the overall structure of the clamp 8 for puncturing, in the alternative embodiment of the present invention, the base 1 includes an upper housing and a mounting plate, the knob 6 is disposed outside the upper housing, the upper housing and the mounting plate together enclose and form a mounting space, at least the portion of the linkage member 4, the first binding clip 2 and the second binding clip 3 for connecting with the linkage member 4 is disposed in the mounting space, that is, the abutting ends of the first binding clip 2 and the second binding clip 3 are disposed in the mounting space, preferably, the clamping ends of the first binding clip 2 and the second binding clip 3 are disposed outside the mounting space to clamp the puncturing sleeve 5. Wherein the first pin 402 and the second pin 404 connect the upper housing and the mounting base plate to prevent the cam 403 and the torsion spring 401 from disengaging. Preferably, the clamp 8 for puncturing comprises a knob 6 provided outside the upper housing for connecting with the linkage 4 to adjust the positional relationship of the first and

second bits

2 and 3. The setting protects the tightness and stability of the overall structure installation of the clamp 8 for puncture, and is convenient to control, thereby improving the operation efficiency.

In order to facilitate control of the gripping and releasing of the grip 8 for puncturing, it is preferable that the position of the knob 6 corresponding to the surface of the upper case is marked when the corresponding cam 403 is rotated to release and grip. Such as the flags OFF and ON.

The utility model discloses an actual practical process for anchor clamps of puncture can be:

the knob 6 is rotated clockwise to an OFF position, the cam 403 is driven to rotate, the cam 403 pushes the first forceps head 2 and the second forceps head 3 to slide to the abutting surface 4032 along the convex surface of the outer peripheral surface of the first forceps head and the second forceps head, so that the formed jaws are closed, at the moment, the cam 403 and the jaws are in a self-locking state, and the jaws clamp the puncture sleeve 5;

when the clamp for puncture needs to be retracted after puncture is completed, the knob 6 is rotated anticlockwise from the OFF position to the ON position, at this time, the cam 403 no longer plays a role in pushing and limiting the first binding clip 2 and the second binding clip 3, the first binding clip 2 and the second binding clip 3 are automatically opened under the action of the torsion spring 401, the abutting part of the first binding clip 2 and the second binding clip 3 slides to the positioning notch 4031, at this time, the clamp 8 for puncture is completely separated from the puncture sleeve 5, and then the connecting rod 0 is pulled to complete the recovery of the clamp 8 for puncture;

the utility model provides a puncture robot, this puncture robot include connecting rod 0, puncture sleeve 5, pjncture needle 7 and any kind of above-mentioned anchor clamps 8 for puncture, wherein be used for 8 one sides of anchor clamps of puncture to be connected with connecting rod 0, another is connected with puncture sleeve 5, pjncture needle 7 sets up on puncture sleeve 5.

In the preferred embodiment of the present invention, the groove 101 of the puncture jig 8, the first binding clip 2, and the second binding clip 3 collectively enclose more than half of the circumferential length of the puncture sleeve 5, so as to ensure clamping of the puncture sleeve 5. The utility model discloses a piercing robot only needs swing knob 6 can control first binding clip 2 and second binding clip 3 and press from both sides tightly or release to the puncture sleeve 5 in the recess 101 of base 1, greatly reduced in the operation process to the mistake of puncture needle 7 touch, easy operation is swift, thereby solved among the correlation technique because current terminal anchor clamps can be influenced by multiple factors such as position, puncture needle stop device, lead to the puncture needle can not be safe quick recovery technical problem of anchor clamps after accomplishing the puncture.

The utility model provides an anchor clamps and puncture robot for puncture has solved the problem that needle holder anchor clamps can't be retrieved fast after the puncture is accomplished in clinical from overall structure. In addition, only the puncture sleeve needs to be replaced aiming at puncture needles of different models, and the tail end clamp does not need to be disassembled and replaced. Convenient and fast to use, saved the puncture time.

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.
