To solve existing Porta blocking-up device there are it is complicated, component is more, cumbersome and can not realize integrated ask
Topic.
To achieve the above object, the utility model provides integrated self-locking hepatic portal occlusion in a kind of Laparoscopic Liver Resection operation
Device, the occluding device include band and lock, its length direction is provided with several latches, the bundle on the band
One end of band is fixedly connected with one end of the lock, and the lock is internally provided with the locking hole through the lock, described
Locking hole is equipped with fixed latch close to the inner wall of the other end of lock, and cutting window is offered on the side wall of the lock, described
Window is cut to connect with the locking hole.
Preferably, it is provided with concave surface on the end face of described lock one end.
Preferably, the inner wall of the locking hole forms guide surface to contract.
Preferably, the band and lock are integrally formed.
Preferably, the material of the band and lock is medical low sensitiser.
Preferably, the other end vertical view of the band is trapezoidal.
The utility model has the following advantages that：Integrated self-locking hepatic portal resistance in the Laparoscopic Liver Resection operation of the utility model
Disconnected apparatus structure is simple and convenient to operate, component is less and whole device integrated design facilitates its use.

Specific embodiment
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
Embodiment 1
As illustrated in fig. 1 and 2, integrated self-locking Porta blocking-up device includes band 1 and lock in Laparoscopic Liver Resection operation
Button 2, the upper surface of band 1 are provided with several latches 11, the side of one end and one end of lock 2 of band 1 along its length direction
Edge is fixedly connected, and band 1 and lock 2 are integrally formed, and band 1 is the medical flexible silica type material of low sensitization.Lock 2
Material is rigid medical plastic, and lock 2 in tubular construction, latches 2 locking hole 21 through lock 2 that is internally provided with, locking
Hole 21 is equipped with fixed latch 22 close to the inner wall of the other end of lock 2, and locking hole 21 is larger close to one end size of band 1,
The size of the other end is slightly smaller than the size of band 1, ensure with pull band 1 from 21 forward direction of locking hole pass through when, band 1 can oneself
By passing through locking hole 21, reversely pull fixation latch 22 during band 1 that can be mutually twisted with the latch 11 on band 1, no farad
Dynamic band 1, so as to fulfill the auto-lock function of Porta blocking-up device.Lock 2 side wall on offer cut window 23, cut window 23 with
Locking hole 21 connects, and when needing to discharge hepatic portal blood flow, cutting window 23 can be put in laparoscope scissors and cuts band 1, you can is released
Hepatic portal is put, restores blood flow.
Further, in order to ensure that hepatic portal is preferably bonded with band 1 and lock 2, band 1 selects the flexibility of thinner thickness
Material ensures that band 1 can be bent with any angle, latches and is provided with concave surface 24, the radian of concave surface 24 and liver on the end face of 2 one end
The radian matching of door, in addition, the surface of band 1 and lock 2 is smooth, guarantee will not cause secondary injury to hepatic portal.
Further, in order to shorten the time for being arranged Porta blocking-up device in surgical procedure, locking hole 21 is close to band 1
One end size it is larger, ensure use when band 1 the other end easily enter in locking hole 21, simultaneously as locking hole 21
Inner wall form guide surface 25 to contract, the other end vertical view of band 1 is trapezoidal, passes through guide surface 25 and guides band 1
The other end ensures that the other end of band 1 is easy to be pierced by from locking hole 21.Greatly shorten be arranged Porta blocking-up device when
Between, improve the safety of operation.
As shown in Figures 3 and 4, the work of integrated self-locking Porta blocking-up device during the utility model Laparoscopic Liver Resection is performed the operation
Principle：In surgical procedure, the Porta blocking-up device in the present embodiment is put into abdominal cavity by laparoscope stamp card, by 1 ring of band
Around hepatic portal after a week, the other end of band 1 is stretched into the locking hole 21 of lock 2, and from locking hole by laparoscope holding forceps
21 one end with fixed latch 22 are pierced by, and bundle can be locked by the other end grasping band 1 of lock 2 rotate by a certain angle
Band 1 realizes hepatic portal occlusion.When needing to discharge hepatic portal blood flow, cutting window 23 can be put in laparoscope scissors and cuts band 1, i.e.,
Releasable hepatic portal restores blood flow.The volume of Porta blocking-up device after finally cutting does not increase, can by stab card hole or other
Approach is drawn off.Integrated self-locking Porta blocking-up device is simple in structure in the Laparoscopic Liver Resection operation of the utility model, grasps
Work is convenient, component is less and whole device integrated design facilitates its use.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be modified or improved, this is apparent to those skilled in the art
's.Therefore, the these modifications or improvements on the basis of without departing from the spirit of the present invention, belonging to the utility model will
