Laparoscopic vascular disconnector

Abstract

The invention discloses a laparoscopic vascular disconnector. The device includes a left tissue clamping device, a right tissue clamping device, a tissue clamp, central scissors of the clamping devices, a connecting rod, a fixed handle, a movable handle, a pincer barrel body, movable links, fixed links and tissue clamp fixing grooves. When laparoscopic vascular cutting operation techniques are conducted with the laparoscopic vascular disconnector, the two sides of a blood vessel can be quickly clamped with the tissue clamp, after it is ensured that the blood vessel is clamped definitely and completely, the device is pushed forward, the central scissors of the clamping devices can cut the blood vessel off quickly, the operation time is saved, and the tissue clamp is firm and cannot slip. Meanwhile, according to the cut end of the tissue, it is judged whether the tissue is the blood vessel, a bile duct or other tissue, it is prevented that when an electric knife, an ultrasonic knife or an energy platform is used for cutting off the tissue, which kind of the tissue is cannot be determined, and the problem of rebleeding after thick blood vessels are cut is solved; through clinical practice, the device is convenient, quick and flexible for the operation techniques, and the operation safety is effectively improved.

Description

technical field [0001] The invention relates to the technical field of laparoscope application, in particular to a laparoscope-used vessel disconnector. Background technique [0002] With the development of modern medicine, minimally invasive surgery has become the development direction of today's surgical operations. Minimally invasive surgery has the advantages of less trauma, faster recovery, and less pain, and has become the common goal and direction of modern medicine. In some respects, laparoscopic techniques are gradually replacing traditional surgery. During laparoscopic operations, we found that when electrocautery, ultrasonic scalpel, and energy platform are used for blood vessel isolation, although bleeding is not easy, due to the cauterization effect of electrocoagulation, electrocoagulation After the blood vessel is cut off, the type of blood vessel cannot be judged by the broken end, especially when the bile duct, lymphatic vessel, and blood vessel need to be d...

Problems solved by technology

In some respects, laparoscopic technology is gradually replacing traditional surgery. During laparoscopic operation, we found that although electrocautery, ultrasonic scalpel, and energy platform are used for blood vessel isolation, although bleeding is not easy, due to the cauterization effect of electrocoagulation, electrocoagulation After the blood vessel is cut off, the type of blood vessel cannot be judged by the broken end, especially when the bile duct, lymphatic vessel, and blood vessel need to be distinguished, which is even more inconvenient

At the same time, occasionally there are too many and thick blood vessels to be electrocoagulated, or the blood vessels that need to be cut are thicker, which is beyond the ability of electric knife, ultrasonic knife, or even energy platform to cut blood vessels, resulting in blood coagulation and hemostasis at that time. The effect is satisfactory, but later, due to the increase of the patient's blood pressure or other reasons, the blood vessels that were originally coagulated will bleed again, which will bring unnecessary mental pressure to the patient and the surgeon.

For example, when using tissue clips to cut blood vessels, the existing technology is more troublesome, that is, it is necessary to clip the tissue clips twice to clip the two ends of the bare blood vessels, and then use scissors to clip the two ends by the tissue. Blood vessel cutting, the process of cutting blood vessels, requires surgical instruments to repeatedly enter and exit the puncture cannula at least three times, wasting precious surgical time

Inconvenience to the doctor
