Detailed Description
The following description will further explain embodiments of the present invention by referring to the figures and the specific embodiments. It should be noted that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work based on the embodiments of the present invention belong to the protection scope of the present invention.
Referring to fig. 1 to 3, which are schematic structural views of a blood vessel ligation surgical device according to the present invention, a cap 8 connects an inner vessel clip 17 and an outer vessel clip 16 in their lumens and limits them so that they can move only in a synchronous linear motion in the cap 8. Two intravascular clamps 17 for clamping the blood vessel are arranged in the two extravascular clamps 16 which are correspondingly connected with the intravascular clamps. In the clip cover 8, the collet of the endovascular clip 17 is held open by the extravascular clip 16, and after protruding from the clip cover 8, will grip the vessel and separate from the clip cover 8. The limiting thin cover 5 is arranged on the front sleeve 7, and a limiting structure is arranged on the limiting thin cover to connect the front sleeve 7 with the clamping cover 8. After one end of the limiting thin cover 5 is pressed down, the clamping cover 8 can be separated from the front sleeve 7, and the vascular clamp can be conveniently replaced in the clamping cover 8. The clamp pushing device 11 penetrates through the interior of the front sleeve 7, the tail end of the front sleeve is provided with two slender cylindrical solid tubes, and the two slender cylindrical solid tubes can pass through the inner cavity of the clamp cover 8 after being driven by the handle 10, meanwhile, the two pushing blocks 15 in the clamp cover 8 are pushed forwards, so that the blood vessel inner clamp 17 and the blood vessel outer clamp 16 move until the blood vessel clamp is separated from the clamp cover 8 to clamp the blood vessel. The inner ring of the reset spring 12 is arranged on the outer cylindrical surface of the push clamp 11, and the outer ring is coated and limited by the rear barge 2. After the grip 10 is released, the return spring 12 releases elastic potential energy to return the clip pusher 11 to the initial position, so as to achieve the effect of return.
The scalpel head 14, the scalpel handle 13 and the scalpel push tube 1 are sequentially and fixedly connected, penetrate through the clamp pushing device 11 and are not in contact with the clamp pushing device 11. When the scalpel is loaded, the notch of the scalpel head 14 is aligned with the knife edge at the front part of the scalpel handle 13, and the scalpel can be installed by pulling backwards with slight force. The tail end of the scalpel handle 13 is cylindrical and is in threaded fit with the scalpel push tube 1. The scalpel push tube 1 penetrates through the inner cavity of the knob cover 6, and the knob cover 6 is in threaded connection with the rear refuting tube 2. The scalpel push tube 1 is provided with a transmission structure, and when the scalpel push tube is located at an initial position and does not extend into the rear barge tube 2, the blood vessel clamp is pushed to advance and clamp a blood vessel by pressing the handle 10, so that the scalpel cannot be pushed out; when the scalpel push tube 1 is pushed into the refuting tube 2, the transmission structure of the scalpel push tube 1 and the rotary buckle 9 form contact connection in the inner cavity of the refuting tube 2. The rotary buckle 9 rotates by taking the rivet 3 arranged on the rear refuting pipe 2 as a center, and can convert the small displacement motion of the grip button 4 into the large displacement motion of the scalpel push pipe 1, thereby saving the space of hands and reducing the operation difficulty. The handle knob 4 on the handle 10 is pressed, the rotating buckle 9 can drive the scalpel push tube 1 to move forward, and the scalpel head 14 is pushed out from the clamping cover 8 to cut off the blood vessel between the two vascular clamps.
Before the main surgeon performs a vascular ligation operation, the vascular inner clip 17 and the vascular outer clip 16 are first placed on the clip cover 8, and the scalpel head 14 is placed on the scalpel handle 13. When performing a blood vessel ligation operation, a doctor uses a single hand to hold the rear barge 2 and the handle 10 and align the device with a blood vessel to be cut, then presses the handle 10 to make the push clamp 11 push the push block 15 so as to make the inner vessel clamp 17 and the outer vessel clamp 16 separate from the clamping cover 2 to clamp the blood vessel, and then releases the handle 10 to make the reset spring 12 push the push clamp 11 back to the initial position. The scalpel push tube 1 is pushed into the refuting tube 2 and is in contact with the rotary buckle 9, the handle button 9 is pressed to push out the scalpel head 14, and the cutting of the blood vessel is completed. By this, a surgical procedure of clamping a blood vessel and then cutting the blood vessel can be accomplished on one device. The device simplifies complicated steps, one blood vessel is ligated without replacing a vascular clamp and additionally inserting a scalpel, the operation difficulty of a doctor is reduced, operation time and damage to a patient are reduced, and the success rate of the operation is improved.
In summary, the vascular ligation surgical device of the present invention integrates two double-layered vascular clamps and a scalpel into one device, and realizes the surgical procedure of clamping and then cutting a blood vessel on one device sequentially by using the pushing device and the limiting device, thereby saving the surgical time, reducing the surgical steps, avoiding unnecessary injuries and infections caused by manual operations to patients, and improving the success rate of the surgery.
