Abstract
The invention relates to the technical field of medical apparatuses and discloses a separable portal vein blocker under a laparoscope. The separable portal vein blocker consists of a pair of vein blocking pincers and a blocking pincer manipulator. The pair of vein blocking pincers consists of a pair of pincer limbs (1), a limb connecting shaft (2) and a spring (3), wherein the pair of pincer limbs is in cross connection through the limb connecting shaft; front arms (1.1) of the pincer limbs are cambered and bent; and the tail parts of rear arms (1.2) of the pincer limbs are provided with lock catches (1.3). The blocking pincer manipulator consists of an operating rod and an operating rod shell (4), wherein a pair of chutes (4.2) is formed on the two sides of the tail part of the operating rod shell; the operating rod consists of a control handle (5), a first linkage rod (6), a second linkage rod (7) and a fixing shaft (8); and lock holes (7.1) matched with the lock catches (1.3) of the rear arms of the pincer limbs are formed on the opposite faces of the front ends of the two linkage rods, so that the linkage rods are linked with the veining blocking pincers. The separable portal vein blocker has a simple structure, is convenient to use and solves the problem of blocking portal vein bleeding of a liver operation under the laparoscope.
Description
Technical field
The present invention relates to technical field of medical instruments, is a kind of separable portal vein block device under the 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 by the blood flow that uses various vascular forcepss, blocking-up band blocking door vein etc. and reduces hemorrhage purpose, but traditional modus operandi 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, liver inner structure complexity, the hepatic vein wall is thin, in case the careless manipulation hepatic vein breaks a large amount of CO in the pneumoperitoneum
2Enter 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 portal vein block device of use down according to pylic trend of liver and residing position.
The present invention is made up of portal vein blocking-up pincers and blocking-up pincers manipulator.Portal vein blocking-up pincers are by the pair of jaws limbs, limbs connecting axle and spring are formed, the pair of jaws limbs are by the cross-shaped connection of limbs connecting axle, with the limbs connecting axle is that boundary's clamp limbs are divided into forearm and postbrachium two parts, forearm is convexly curved, having certain width makes the clamp blood vessel enough firm and cause the blood vessel injury minimum, article two, the forward surface of forearm 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 postbrachium, is enough to make two forearms to clamp the mutual interlock of bar shaped tooth, when postbrachium is subjected to external force pressurization compression spring, article two, forearm unclamps and is forked, and the afterbody of postbrachium is provided 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, and two sides of tail is provided with a pair of symmetric chute; Stick is made up of control handle, first trace, second trace and fixed axis, 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, the chute of stick shell two sides of tail is stretched out at the action bars two ends, can slide before and after chute; The connecting rod of control handle is connected with two first isometric traces by fixed axis, two first traces are connected with two second isometric traces by fixed axis respectively, two second traces intersect by 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 lock door vein blocking-up pincers are operated.
During use, push away before operating the control handle of finger ring with finger stick, the connecting rod of control handle drives first trace and drives second trace by first trace second trace front end is opened, the snap close of the postbrachium afterbody that the portal vein blocking-up is clamped places the relevant position of the lockhole of the second trace front end again, retreat stick, drive first trace and second trace closes up, the afterbody snap close of portal vein blocking-up pincers postbrachium is locked in the lockhole of the second trace front end, with peritoneoscope the forearm of portal vein blocking-up pincers is delivered to the affected part corresponding site routinely then, continue to retreat stick, the second trace front end closes up and stresses on the postbrachium of portal vein blocking-up pincers, forearm is unclamped be forked, so portal vein is placed in the branch prong, before push away stick again, the second trace front end is opened, the lockhole that the afterbody of portal vein blocking-up pincers postbrachium is broken away from the second trace front end, portal vein blocking-up pincers postbrachium clamps two forearms under the effect of spring force, the portal vein pipe clamp is lived, thereby reach the purpose of blocking blood flow.
The present invention is simple in structure, and is easy to use, because portal vein blocking-up pincers can separate with blocking-up pincers manipulator, the postbrachium of door hepatic vein blocking-up pincers is very short, and is therefore few to blocking of operative site, helps carrying out under peritoneoscope liver neoplasm or hepatic haemangioma excision.The invention solves the difficult problem of the blocking-up of operation on liver under peritoneoscope liver portal vein blood vessel blood flow, make and carry out under the peritoneoscope liver neoplasm or the hepatic haemangioma excision might be implemented.
