Specific embodiment
Below in conjunction with attached drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 4, the utility model provides a kind of instrument bindiny mechanism for laparoscopic surgery robot,
It includes instrument shaft 41, and wherein the first end of instrument shaft 41 is provided with instrument 42, and the second end of instrument shaft 41 is disposed with solid
Determine device and clamping close device.
The second end of instrument shaft 41 is connected with retainer 3.Specifically, instrument shaft 41 is connected with the shaft 33 on retainer 3.
It is provided with fixed device on the outer wall of instrument shaft 41, after instrument shaft 41 is inserted into shaft 33, is consolidated the two by fixed device
It is fixed.
In one embodiment, as shown in Fig. 2, fixed device includes the first card slot 44 being arranged on instrument shaft 41.
Specifically, the second end of instrument shaft 41 is provided with spacing head 413, and restraining position ring block is arranged on the outer wall of spacing head 413
416, the first card slot 44 is arranged on stop collar 416.Wherein, the first card slot 44 extends along the axial direction of instrument shaft 41.
It is provided with shaft 33 on the side wall of retainer 3, positioning protrusion 331 is provided in shaft 33, instrument shaft 41 is inserted into
After in shaft 33, positioning protrusion 331 fastens with the first card slot 44, to keep instrument shaft 41 complete in radial directions with shaft 33
At positioning.
Further, it is provided with external screw thread in shaft 33, threaded sleeve 43, thread bush are provided on the outer wall of instrument shaft 41
