With the continuous development of medical technology in the changing times, various medical devices have been widely used in the medical field, especially vascular ligation devices are also operated and used in a large number of operations, such as laparoscopic cholecystectomy, treatment of neck blood vessels Cracked and so on. Vascular ligation instruments first apply a blood vessel clamp to clamp one part of a blood vessel, and then use the first blood vessel clamp as a reference, near it 10mm Use a vascular ligation instrument to reinstall and place a second vascular clip at the location, and finally use a scalpel to cut the blood vessel between the two vascular clips to achieve the purpose of ligation and treatment. If a blood vessel is ligated, the surgeon needs to change the vascular clamp at least once and insert an extra scalpel. However, for tissues with densely distributed multiple blood vessels, There are often many blood vessels that need to be ligated and cut. The chief surgeon needs to use the vascular ligation instrument to change the vascular clamp multiple times, and accurately insert a scalpel between the vascular clamps to cut off the blood vessels. This will not only prolong the operation time, but also put forward higher requirements on the doctor's attention and technology. Ingress and egress of instruments can also cause damage to patient tissue. Therefore, it is necessary to find a vascular ligation surgical device that integrates two vascular clips and a scalpel in one device, simplifying the complicated steps.

 detailed description

The specific implementation of the present invention will be further described below with reference to the drawings and specific embodiments. It should be noted that the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all those obtained by a person of ordinary skill in the art without creative efforts Other embodiments belong to the protection scope of the present invention.

 As shown in FIG. 1 to FIG. 3, it is a schematic structural diagram of a vascular ligation operation device according to the present invention. It is connected with the outer layer clamp 16 of the blood vessel in its inner cavity and restricted so that they can only perform synchronous linear motion in the clamp cover 8. Two inner vessel clamps for clamping blood vessels 17 Two outer vessel clamps 16 connected to the corresponding vessels 16 Inside. In the clip cover 8, the chuck of the inner blood vessel clip 17 is restricted by the outer blood vessel clip 16 to be kept open. After protruding from the clip cover 8, the blood vessel is clamped and separated from the clip cover 8. Limit thin cover 5 It is installed on the front sleeve 7, and there is a limiting structure to connect the front sleeve 7 and the clamp cover 8. After pressing one end of the limiting thin cover 5, the clamp cover 8 can be separated from the front sleeve 7, which is convenient for the clamp cover 8 Replace the vascular clamp. The pusher 11 passes through the inside of the front sleeve 7 and ends with two slender cylindrical solid tubes. After being driven by the grip 10, it can pass through the inner cavity of the clamp cover 8 and simultaneously bear against the two inside the clamp cover 8. Push block 15 moves forward to move the inner vessel clamp 17 and the outer vessel clamp 16 until the vessel clamp is released from the clamp cover 8 to clamp the vessel. Return spring 12 Inner ring mounted on pusher 11 On the outer cylindrical surface, the outer ring is covered and restricted by the rear barge 2. After releasing the grip 10, the return spring 12 releases the elastic potential energy, so that the pusher 11 is returned to the initial position to achieve the effect of resetting.

 The scalpel head 14, the scalpel handle 13 and the scalpel push tube 1 are fixedly connected in order, and pass through the pusher clamp 11 and are connected with the pusher clamp 11 No contact. When loading the scalpel, the notch of the scalpel head 14 is aligned with the scoring at the front of the scalpel handle 13, and it can be installed by pulling it back slightly. The scalpel handle 13 is cylindrical at the end and pushes the tube with the scalpel 1 For threaded fit. The scalpel push tube 1 passes through the inner cavity of the knob cover 6, and the knob cover 6 and the rear pipe 2 are threadedly connected. The scalpel push tube 1 is designed with a transmission structure. When it is in the initial position and does not extend into the rear tube 2 In the middle, pressing the grip 10 will push the vascular clamp forward and clamp the blood vessel without pushing out the scalpel; when the scalpel push tube 1 is pushed back into the bard tube 2, the transmission structure and rotation of the scalpel push tube 1 Clip 9 at the rear barge 2 forms a contact connection in the inner cavity. The rotating buckle 9 rotates around the rivet 3 installed on the rear barge 2 to convert the small displacement movement of the grip button 4 into a scalpel pushing tube 1 Large displacement movement, saving hand space and reducing the difficulty of operation. Press the knob 4 on the handle 10 and rotate the buckle 9 to drive the scalpel push tube 1 forward, and then the scalpel head 14 from the clamp cover 8 The medium ejection cuts off the blood vessel between the two vessel clips.

 Before the surgeon performs the vascular ligation operation, the inner vessel clamp 17 and the outer vessel clamp 16 are loaded in the clamp cover 8 and the surgical blade 14 Load on the scalpel handle 13. When performing a vascular ligation operation, the doctor uses one hand to hold the rear tube 2 and the grip 10 and point the device at the blood vessel to be cut, then press the grip 10 to push the clamp 11 Push the pusher block 15 to release the inner vascular clamp 17 and the outer vascular clamp 16 from the clamp cover 2 and clamp the blood vessel to release the grip 10 Let the return spring 12 Push the clamp 11 Push back to the initial position. Push the scalpel push tube 1 back into the barge 2 and make contact with the rotary buckle 9, and press the grip button 9 to push out the scalpel head 14 To complete the cutting of blood vessels. So far, the operation of clamping the blood vessel and then cutting the blood vessel can be completed on one device. Such a device Simplify the complicated steps, ligate a blood vessel without changing the vascular clip and inserting a scalpel, reducing the operation difficulty of the chief surgeon, thereby reducing the operation time and damage to the patient, and improving the success rate of the operation.

In summary, a vascular ligation operation device of the present invention integrates two double-layer blood vessel clips and a scalpel on one device, and realizes orderly on one device by using a pushing device and a limiting device. Complete the surgical procedure of clamping the blood vessel and then cutting the blood vessel, thereby saving the operation time, reducing the number of surgical steps, avoiding unnecessary injuries and infections caused to the patient by human operation, and improving the success rate of the operation.
