the first pull ring 402 is arranged at the rear end of the adjusting column 401.
Thus, since the front end of the adjusting column 401 is inserted into the installation channel 101 from the rear end of the handle 10 and can slide along the length direction of the installation channel 101, and the first pull ring 402 is arranged at the rear end of the adjusting column 401, in the using process, medical personnel can pull the adjusting column 401 through the first pull ring 402 to drive the adjusting wire 102 to control the lithotomy forceps 30 to be opened, and the operation is simpler and more convenient, and time and labor are saved.
Preferably, in one embodiment of the present invention, the locking mechanism 50 includes a pull rod 501, a second pull ring 502 and two catches 503.
The upper end of the pull rod 501 is formed to be conical, a mounting groove 5011 is arranged in the adjusting column 401, one end of the mounting groove 5011 penetrates through the rear end of the adjusting column 401, and the front end of the pull rod 501 is inserted into the mounting groove 5011 and can slide along the length direction of the mounting groove 5011.
The second pull ring 502 is connected to the tail end of the pull rod 501 for pulling the pull rod 501.
A through groove 5012 is formed in the inner side wall opposite to the upper end of the mounting groove 5011, and the two clamping pieces 503 can be arranged in the through groove 5012 in a left-right sliding mode.
The opposite inner side surfaces of the installation channel 101 are provided with a guide groove 103, a groove wall opposite to the two guide grooves 103 is provided with a plurality of limiting grooves 104, one end of each of the two clamping members 503 extends into the guide groove 103 and is inserted into one of the limiting grooves 104, and the other end of each of the two clamping members 503 is abutted against the outer surface of the pull rod 501.
In this way, since the upper end of the pull rod 501 is formed into a cone shape, one end of each of the two retaining members 503 extends into the guide groove 103 and is inserted into one of the limiting grooves 104, and the other end of each of the two retaining members 503 abuts against the outer surface of the pull rod 501, when the pull rod 501 moves upwards, the upper end of the pull rod 501 can push one end of each of the retaining members 503 to be inserted into the limiting groove 104, so that the adjusting column 401 is fixed to lock the lithotomy forceps 30 in the current state.
Preferably, in an embodiment of the present invention, a first return spring 5013 is sleeved on the pull rod 501, a first limit protrusion 5014 is disposed in the middle of the pull rod 501, a second limit protrusion 5015 is disposed on a groove wall of the mounting groove 5011, the first return spring 5013 is disposed between the first limit protrusion 5014 and the second limit protrusion 5015, a second return spring 5031 is sleeved on each of the two clamping members 503, a third limit protrusion 5032 is disposed on an outer surface of each of the two clamping members 503 near the other end, and the second return spring 5031 is disposed between the third limit protrusion 5032 and the groove wall of the mounting groove 5011.
Based on the above, it should be noted that the initial state of the locking mechanism 50 is a locking state, and at this time, the second return spring 5031 is in a contracted state, when the adjusting column 401 needs to be moved, the second pull ring 502 can be pulled backward, so that the pull rod 501 moves backward, at this time, the other end of the retaining member 503 loses the abutting force, the second return spring 5031 resets, and can push the retaining member 503 to move in the direction of the pull rod 501, so that the abutting member moves out of the limiting groove 104, at this time, the adjusting column 401 can move, otherwise, when the adjusting column 401 needs to be locked, the second pull ring 502 can be released, so that the pull rod 501 moves upward by being pushed by the first return spring 5013, so that the retaining member 503 is pushed into the limiting groove 104, and the overall structure is simple, the locking is reliable, convenient operation is swift, labour saving and time saving.
Preferably, in one embodiment of the present invention, a third pull ring 105 is provided at the rear end of each of the two opposite outer sides of the handle 10.
Therefore, the third pull ring 105 is arranged at the rear ends of the two opposite outer side surfaces of the handle 10, so that the handle 10 can be conveniently held by medical personnel through the third pull ring 105 in the using process.
