Description
Technical field
The present invention relates to technical field of medical instruments, is separable hepatic vein block device under a kind of peritoneoscope that uses when being used for carrying out hepatectomy under the peritoneoscope.
Background technology
Clinically, excision being adopted in the treatment of liver neoplasm is most effectual way.Thereby conventional hepatotomy operation reaches through the blood flow that uses various vascular forcepss, blocking-up band blocking-up hepatic vein etc. and reduces hemorrhage purpose.Hepatic vein is one of human body large vein, through the clamp hepatic vein, the hepatic vein blood flow is controlled, and be one of hemorrhage mode of the important minimizing of conventional hepatotomy operation, but conventional surgical mode wound is big, and complication is many, recovers slow.Both at home and abroad the colleague places hope on laparoscopic surgery very early, reducing wound, and fast track rehabilitation, and carried out arduous exploration for it.The hemostasis problem that the difficult problem that the laparoscopic surgery of liver neoplasm is run into is a blood vessel, because liver matter is crisp, the liver inner structure is complicated, the hepatic vein wall is thin, in case the careless manipulation hepatic vein breaks a large amount of CO in the pneumoperitoneum
2Get into pulmonary circulation and will cause fatal gas embolism, might make the abdomen hepatectomy of opening that the liver neoplasm excision is more traditional under the peritoneoscope have more risk.But shape, size and the structure of existing clinical employed vascular forceps, blocking-up band all are not suitable for laparoscopic surgery, so be difficult to extensively carry out liver neoplasm or hepatic haemangioma excision under the peritoneoscope so far.
Summary of the invention
The present invention provides a kind of simple in structure, easy to use, suitable peritoneoscope separable hepatic vein block device of use down according to hepatic venous trend of liver and residing position.
The present invention is made up of hepatic vein blocking-up pincers and blocking-up pincers manipulator.Hepatic vein blocking-up pincers are made up of pair of jaws limbs, limbs connecting axle and spring, and the pair of jaws limbs are that boundary's clamp limbs are divided into forearm and postbrachium two parts through the cross-shaped connection of limbs connecting axle with the limbs connecting axle; Forearm is hook solid, and the forward surface of two forearms is provided with complementary horizontal bar shaped tooth, in case slippage during the clamping blood vessel; And can prevent to crush blood vessel, and postbrachium is the pincers handle, both ends of the spring is individually fixed on the forward surface of two postbrachiums; Under not afterburning situation, the elastic force of spring struts two postbrachiums, is enough to make two forearms to clamp; Article two, the mutual interlock of horizontal bar shaped tooth on the forearm forward surface, when postbrachium received external force pressurization compression spring, two forearms unclamped and are forked; Article two, the afterbody of the postbrachium outside is respectively equipped with snap close, is used for being connected with blocking-up pincers manipulator.Blocking-up pincers manipulator is made up of stick and stick shell, and the stick shell is placed in outside the stick.The tail end of stick shell is dome shape; Two sides of tail is provided with a pair of symmetric chute, and stick is made up of control handle, first trace, second trace and fixed axis, and control handle is made up of connecting rod, action bars and operation finger ring; Connecting rod is connected with action bars is T-shaped; The operation finger ring is positioned at the action bars two ends, and the chute of stick shell two sides of tail is stretched out at the action bars two ends, can before and after chute, slide; The connecting rod of control handle is connected with two first isometric traces through fixed axis; Two first traces are connected with two second isometric traces through fixed axis respectively; Two second traces intersect through fixed axis and are connected in the front end of stick shell and stretch out shell; The forward surface of two second trace front ends is provided with the lockhole that the snap close with clamp limbs postbrachium afterbody is complementary, so that locking hepatic vein blocking-up pincers are operated.
During use, push away before operating the control handle of finger ring with stick with finger, the connecting rod of control handle drives first trace and drives second trace through first trace second trace front end is opened; Again the snap close of the postbrachium afterbody of hepatic vein blocking-up pincers is placed the relevant position of the lockhole of the second trace front end, retreat stick, drive first trace and second trace closes up; The snap close of postbrachium afterbody is locked in the lockhole of the second trace front end, with peritoneoscope hepatic vein blocking-up pincers forearm of the present invention is delivered to the affected part corresponding site by routine then, continue to retreat stick; The second trace front end closes up and stresses on the postbrachium of hepatic vein blocking-up pincers, forearm is unclamped be forked, and hepatic vein is placed in the branch prong; Before push away stick again; The second trace front end is opened, the snap close of postbrachium afterbody is broken away from the lockhole of the second trace front end, postbrachium clamps two forearms under the effect of spring force; The hepatic vein blood vessel is clamped, thereby reached the purpose of blocking blood flow.
The present invention is simple in structure, and is easy to use, because hepatic vein blocking-up pincers can separate with blocking-up pincers manipulator, the postbrachium of hepatic vein blocking-up pincers is very short, and is therefore few to blocking of operative site, helps under peritoneoscope, carrying out liver neoplasm or hepatic haemangioma excision.The invention solves the difficult problem of the blocking-up of operation on liver under peritoneoscope liver hepatic vein vascular flow, make and carry out under the peritoneoscope liver neoplasm or the hepatic haemangioma excision might be able to implement.
