Description

Knot pusher for vascular ligation under laparoscopic surgery and method of use thereof

technical field

The invention relates to a knot pusher for vascular ligation under laparoscopic surgery and a using method thereof, belonging to the field of medical devices.

Background technique

At present, doctors ligate blood vessels under laparoscopic surgery: the ligation thread enters the body from the wound, bypasses the target blood vessel, and then leads out of the body. The way of opening both ends of the ligature to the outside makes the knot of the ligature move toward the target blood vessel, and finally tighten the target blood vessel. This vascular ligation method under laparoscopic surgery has many inconveniences such as difficult operation, inconvenient, and the joints of the ligation thread are prone to breakage due to friction.

Contents of the invention

The technical problem to be solved by the present invention is to provide a knot pusher for vascular ligation under endoscopic surgery and its use method due to the inconveniences such as difficult operation and inconvenient operation in the current vascular ligation method under endoscopic surgery , In the process of laparoscopic surgery, the doctor can use the knot pusher to ligate the target blood vessel, which can greatly reduce the operation difficulty and increase the convenience, thereby improving the efficiency and effect of the operation.

The technical solution adopted by the present invention to solve the technical problem is: a knot pusher for vascular ligation under laparoscopic surgery, which has a strip-shaped body, a knot push groove formed on the head end of the body, and anti-skid grooves are formed on both sides of the rear of the knot push groove After removing the guide groove, there is an auxiliary wire clamping groove formed on the body at a distance from the head end of the body. The rear part of the body is a handle, which is composed of two elastic handles connected at the front end and parallel to each other. The two elastic handles The gap between the sheets is the clamping groove.

Furthermore, a through hole window is formed at the rear position of the anti-slip guide groove on the body. The existence of the through-hole window can facilitate the doctor to observe the tissue condition on the other side of the through-hole window through the laparoscope during the operation.

Furthermore, the width of the handle at the rear of the body is greater than that at the front of the body. The front part of the body must enter the body from the surgical wound, so it must be relatively slender, while the rear handle is used for holding and clamping the thread, and does not enter the body, so its width is more suitable than the width of the front part of the body.

Further speaking, the inner surfaces of the two elastic handles of the handle are formed with corresponding friction-increasing lines, so that when the doctor presses the two elastic handles of the handle with his hands, the two elastic The handle piece more reliably clamps the ligature in the wire clip groove to prevent the ligature from slipping off.

The above-mentioned method of using the knot pusher for vascular ligation under laparoscopic surgery: During the laparoscopic surgery, when the physician uses the knot pusher for vascular ligation under laparoscopic surgery to ligate the target blood vessel, the ligature wire will first bypass the target blood vessel Finally, a knot is made outside the body, and then one of the ligatures behind the knot is sequentially inserted into the knot pushing groove, anti-slip guide groove, auxiliary thread holding groove and clip of the knot pusher for vascular ligation under endoscopic surgery. Then the doctor holds the handle of the knot pusher for vascular ligation under endoscopic surgery with one hand and presses its elastic handle to clamp the ligature in the clamping groove, and holds the other hand after holding the knot in the other hand A ligature. At this time, the doctor pushes the vascular ligation under the endoscopic surgery forward with a knot pusher, and at the same time pulls the ligature back, so that the ligature on the ligature The knot is pushed forward and eventually tightens the target vessel. The above-mentioned "one of the ligatures after the knot" and "the other ligature after the knot" are actually the same ligature, and the distinction between "two lines" after the knot is only for convenience The distinction is clearly stated.

The beneficial effects of the present invention are: the knot pusher for vascular ligation under laparoscopic surgery of the present invention is exquisite in design, simple in product structure and low in production cost. In the process of laparoscopic surgery, the doctor cooperates with using the knot pusher to ligate the target blood vessel, which can greatly reduce the operation difficulty and increase the convenience, thereby improving the efficiency and effect of the operation.

detailed description

A knot pusher for vascular ligation under laparoscopic surgery, as shown in Figures 1 to 3, it has a strip-shaped body 1, the head end of the body 1 is formed with a knot pushing groove 1-1, behind the knot pushing groove 1-1 Anti-slip guide grooves 1-2 are formed on both sides, and auxiliary thread-holding grooves 1-3 are formed on the body 1 at a distance from the head end of the body 1. The rear part of the body 1 is the handle 1-4, and the handle 1 -4 is composed of two elastic handle pieces 1-4-1 whose front ends are connected and parallel to each other, and the gap between the two elastic handle pieces 1-4-1 is the wire clamping groove 1-5.

A through-hole window 1-6 is formed at the rear position of the anti-slip guide groove 1-2 on the body 1 . The presence of the through hole window 1-6 can facilitate the doctor to observe the tissue condition on the other side of the through hole window 1-6 through the laparoscope during the operation.

The width of the handle 1-4 at the rear of the body 1 is greater than the width at the front of the body 1 . The front part of the main body 1 must enter the body partly from the surgical wound, so it must be relatively slender, while the rear handle 1-4 is used for holding and clamping the thread, and does not enter the body, so its width is wider than that of the front part of the main body 1. for fit.

The two elastic handles 1-4-1 of the handle 1-4 are provided with corresponding friction-increasing patterns on the inner surface, so that when the doctor presses the two elastic handles 1-4 of the handle 1-4 with his hand, 4-1 can make the two elastic handles 1-4-1 more reliably clamp the ligature in the clamp groove 1-5 to prevent the ligature from slipping off.

The above-mentioned method of using the knot pusher for vascular ligation under laparoscopic surgery: During the laparoscopic surgery, when the physician uses the knot pusher for vascular ligation under laparoscopic surgery to ligate the target blood vessel, the ligature wire will first bypass the target blood vessel Finally, a knot is made outside the body, as shown in Figure 4, and then one of the ligatures behind the knot is inserted into the knot-pushing groove 1-1 of the knot-pushing device for vascular ligation in laparoscopic surgery, and the anti-slip guide Guide groove 1-2, auxiliary wire clamping groove 1-3 and wire clamping groove 1-5, and then the doctor holds the handle 1-4 of the knot pusher for vascular ligation under endoscopic surgery with one hand and presses its elastic handle 1 -4-1 to clamp the ligature thread in the clamping groove 1-5, and hold the other ligature thread behind the knot with the other hand. The knot pusher pushes forward, and at the same time pulls the ligature thread being pulled backward, so that the knot on the ligature thread advances forward and finally tightens the target blood vessel. The above-mentioned "one of the ligatures after the knot" and "the other ligature after the knot" are actually the same ligature, and the distinction between "two lines" after the knot is only for convenience The distinction is clearly stated.

The above-mentioned embodiments are only used to illustrate the present invention, rather than to limit the protection of the present invention. Any non-substantial changes made on the basis of the essence of the present invention should fall within the protection scope of the present invention.
