[0006] The utility model discloses a ligation device push rod, which comprises a push rod body, a push head and a fixed stopper, a spring and a rotary cutter.

[0007] As one of the preferred modes, the utility model also comprises a connecting rod which is arranged in front of the fixed stopper and has a front end fixed with the rotary cutter.

[0008] As one of the preferred modes, the connecting rod is a hollow rod, the inner cavity of the connecting rod is communicated with the inner cylinder of the rotary cutter, and a ligation line perforation is arranged on the connecting rod.

[0009] As one of the preferred modes, a ligation line fixing head is arranged on the connecting rod, the ligation line fixing head is a reverse conical structure with a large upper part, a small middle part and a small lower part, and the ligation line fixing head is arranged behind the ligation line perforation.

[0010] As one of the preferred modes, the connecting rod is integrally formed with the push rod body.

[0011] As one preferred embodiment, the rear end of the rotary cutter is provided with an external thread, and the front end of the connecting rod is provided with a corresponding internal thread, and the rotary cutter is threadedly connected to the connecting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the push rod of this utility model is used in conjunction with the external force provided by the matching ligator. When it receives the external force that pushes forward, the entire push rod moves forward, driving the rotary cutter to move forward, thereby cutting the ligating coil inside the rotary cutter. The overall structure is simple and easy to use and operate. Attached Figure Description

[0014] Figure 2 yes Figure 1 A schematic diagram of the structure of the rotary cutter.

[0015] In the attached diagram: push rod body 101, push head 1, fixed stop 2, spring 3, connecting rod 4, rotary cutter 5, sling wire hole 6, sling wire fixing head 7, rotary cutter blade 51. Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1 , Figure 2 As shown, a ligator push rod includes a push rod body 101, a spring 3, a connecting rod 4, and a rotary cutter 5. The push rod body 101 includes a push head 1 and a fixed stop 2. The push head 1 is located at the rear end of the push rod body 101, and its cross-section is larger than that of other parts of the push rod body. In actual use, the push head will connect to or contact other power input sources, such as an output shaft driven by a motor or a manually operated wrench. Its function is to increase the usable area, facilitate use, and ensure power output. The fixed stop 2 is located in the middle of the push rod body and is a protruding annular block. The spring 3 is sleeved on the push rod body 101 in front of the fixed stop 2. The fixed stop blocks one end of the spring. During use, an external force pushes one end of the push head forward. The front of the push rod body is the ligator's gun shell, which inherently blocks the other end of the spring. When the external force pushes the entire push rod body forward, the spring is compressed.

[0018] The rotary cutter 5 is connected to the front end of the push rod body 1, and in this embodiment, the connecting rod 4 is arranged in front of the fixed block 2, and the rotary cutter 5 is connected to the push rod body 1 through the connecting rod 4. Figure 2 As shown in the drawings, the rotary cutter 5 is in a cylindrical structure, and the front end of the rotary cutter 5 is a rotary cutter opening 51; the connecting rod 4 is a hollow rod, and the inner cavity of the connecting rod 4 is in communication with the inner cylinder of the rotary cutter, and a ligation line perforation 6 is arranged on the connecting rod 4; a ligation line fixing head 7 is arranged on the connecting rod 4, and the ligation line fixing head 7 is in an inverted conical structure with a large upper part, a small middle part and a small lower part; the ligation line fixing head 7 is arranged behind the ligation line perforation 6. In use, one end of the ligation rubber ring of the ligation device will pass through the rotary cutter opening of the rotary cutter 5, then enter the connecting rod 4, and finally pass through the ligation line perforation, and finally the end is fixed on the ligation line fixing head, so as to be fixed.

[0019] When the push rod is applied to the corresponding ligation device, an external force is applied to the push rod head by a wrench or a motor, the push rod body moves forward, so as to drive the rotary cutter to move forward, and a block is arranged in the ligation rubber ring, and when the rotary cutter moves to the block, the block will play a role similar to a chopping board, so as to cut the ligation line in the rotary cutter.

[0020] As an embodiment, the connecting rod 4 is integrally formed with the push rod body 101.

[0021] As an embodiment, the rear end of the rotary cutter is provided with external threads, the front end of the connecting rod is provided with corresponding internal threads, the rotary cutter is threadedly connected with the connecting rod, and the rotary cutter can be disassembled and replaced.

[0022] The above only describes preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
