[0021] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clear, the utility model technical scheme will be described clearly and completely below with examples.
[0022] Example 1
[0023] The utility model provides a kind of needle holder under laparoscope, such as Figures 1 to 7As shown, including, the upper operating handle 1, the lower operating handle 2 and the needle holder head 3, the upper operating handle 1 and the lower operating handle 2 are rotatably connected with the rotating shaft 5 inside, the needle holder head 3 is slidably installed with the connecting shaft 4 inside, the needle holder head 3 contains the needle and the needle holder, the needle is rotatably connected to the inside of the needle holder head 3 through the pin shaft, such as Figure 7 As shown, when the connecting shaft 4 moves, the needle rotates, the needle is close to the needle holder, the clamping of the needle is realized, the far end of the connecting shaft 4 from the rotating shaft 5 is slidably connected to the tail of the needle, the opposite ends of the two rotating shafts 5 are rotatably connected to the connecting shaft 4, the rack 6 is symmetrically and fixedly installed inside the upper operating handle 1, the sliding block 7 is slidably installed inside the upper operating handle 1 at the top end position of the rack 6, the push rod 8 is slidably installed inside the sliding block 7, the clamping block 9 is fixedly connected to one end of the push rod 8, the top end of the clamping block 9 is fixedly connected with the stop block 10, the clamping block 9 is clamped at the tooth groove position of the rack 6 by sliding the push rod 8 up and down, and then the stop block 10 is fixed inside the upper operating handle 1, the fixed block 12 is fixedly sleeved on the outer surface of the push rod 8, the spring 11 is fixedly connected to the bottom end of the fixed block 12, and the end of the spring 11 away from the fixed block 12 is fixedly connected to the inside of the push rod 8.
[0024] As shown in Figure 3 and Figure 4 As shown, the shape of the end of the stop block 10 close to the rotating shaft 5 is arc-shaped, the arc-shaped stop block 10 is arranged, the fixing effect of the stop block 10 on the rotating shaft 5 is more stable, and the rotating shaft 5 is fixed in the upper operating handle 1.
[0025] As shown in Figures 2 to 4 The top end of the push rod 8 is fixedly connected with the push handle 13, and the shape of the push handle 13 is arc-shaped, the push handle 13 is installed, the user pushes the push handle 13 at the same time, and the push rod 8 is conveniently driven to move synchronously.
