Interval-adjustable double-clamp clamping application pliers

Abstract

The invention discloses interval-adjustable double-clamp clamping application pliers. The pliers comprise a pair of first clamping application rods, a pair of second clamping heads, a pair of second clamping application rods and an open-close device; first clamping heads are connected with the front portions of all the first clamping application rods; all the second clamping heads are rotatably connected with the tails of the corresponding first clamping heads and can be opened and closed relative to the first clamping heads; the second clamping application rods are connected with the tails ofa pair of second clamping heads respectively; the open-close device which is used for driving a pair of second clamping heads to be opened and closed relative to the first clamping heads is connectedwith a pair of second clamping application rods respectively. In addition, the pliers further comprise an interval adjustment device and a holding device; the interval adjustment device which is usedfor adjusting the interval between a pair of first clamping heads is connected with a pair of first clamping heads respectively; the holding device which is used for supporting the interval adjustment device and facilitates clamping application operation is connected with the interval adjustment device. The adjustable-interval double-clamp clamping application pliers are simple in structure, convenient to operate and high in practicability, according to blood vessels of different sizes, thicknesses and positions and different arteriovenous conditions in clamping application operation, clamping application interval adjustment can be conducted, the blood vessels are ligated, and operation safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a double-clamp clip applier with adjustable distance. Background technique [0002] In clinical practice, laparoscopy is currently one of the most widely used surgical methods, and the most frequently used instrument for vascular ligation is clip applier. After clipping a biological clip or titanium composite clip, the surgeon needs to find a suitable position to clip and close the other end of the blood vessel. The specific position of the other end of the blood vessel can only be determined visually. Basically, more blood vessels were ligated. After the two ends of the blood vessel are closed and tightened, sometimes it is necessary to remove the clip applier from the abdominal cavity and reinstall the components, which seriously affects the operation time and efficiency. [0003] In the prior art, the clip applier whose patent number is CN105476690 and named as o...

Problems solved by technology

After the two ends of the blood vessel are closed and tightened, sometimes it is necessary to remove the clip applier from the abdominal cavity and reinstall the components, which seriously affects the operation time and efficiency

[0003] In the prior art, the clip applicator with the patent number CN105476690 and the name of one-time double clip cutting clip applier is usually used for clip application. The distance between the double clips of the clip applier is constant, and the distance cannot be adjusted.

However, in actual clinical use, according to the size, thickness, location, and arteriovenous of blood vessels, the distance between the two clips cut off by vascular ligation is also very different. Therefore, the distance between the two clips Accurate adjustment is the key to ensure the safety of the operation and prevent bleeding. However, the clip applier of the above patent cannot adjust the distance at any time, so it cannot meet the above requirements, and has the risk of operation failure and bleeding

[0004] In addition, in routine operations, after vascular ligation, it needs to be observed under direct vision to confirm that the ligation is firm before cutting the blood vessel. This is also the key to ensure the safety of the operation. However, the above-mentioned patent cuts the blood vessel directly after ligation, which is not in line with clinical practice.
