In addition, term " first ", " second ", " the 3rd " only for describing object, and can not be interpreted as instruction or hint relative importance.
As Fig. 1, Fig. 2, shown in Fig. 4 and Fig. 5, the Control of Hemorrhage in Laparoscopic Liver door block device that this utility model embodiment provides, comprise the first sleeve pipe 1, second sleeve pipe 2, connection plug 32 and blocking-up ring 31, this blocking-up ring 31 is made up of two blocking unit of stretching out from connection plug 32 front end, two blocking unit can be integrally process with connection plug 32, also can be connection plug 32 heat melt connect or bonding, concrete, one of them blocking unit is to the direction back bending near connection plug 32, and the part of back bending is positioned at the inner side of another blocking unit, and form open ring-type with another blocking unit, what namely two blocking unit formed an opening can include the blocking-up ring 31 that hepatic portal enters liver blood vessel 4 in, connection plug 32 is sheathed in the second sleeve pipe 2, and blocking-up ring 31 stretches out from the front end of the second sleeve pipe 2, concrete, connection plug 32 and the second sleeve pipe 2 can be that interference fit is fixed, also can be welding, the mode such as to be threaded is fixed, the front end sleeve of the second sleeve pipe 2 is located in the first sleeve pipe 1, block ring 31 to stretch out from the front end of the first sleeve pipe 1, the rear end of the second sleeve pipe 2 is stretched out outside the first sleeve pipe 1, facilitate the relative position that hand-held and mobile first sleeve pipe 1 and the second sleeve pipe 2 move, when needs hepatic portal stops blooding, Porta hepatis blocker is stretched into relevant position in human body by puncture casing, by similar aids such as medical calms, hepatic portal being entered liver blood vessel 4 is placed in blocking-up ring 31, then driven forward first sleeve pipe 1, the direction making the first sleeve pipe 1 enter liver blood vessel 4 to hepatic portal is close, blocking-up ring 31 is taken in the first sleeve pipe 1, tighten up and block ring 31, thus reach the hemorrhage effect of vascular inflow occlusion.
For the ease of hand-held, preferably, as shown in Figure 1, Figure 2 and Figure 4, in the rear end of the first sleeve pipe 1, first handle 11 is set, in the rear end of the second sleeve pipe 2, second handle 21 is set, first handle 11 and second handle 21 can be that socket or heat are melted and is connected on the first sleeve pipe 1 and the second sleeve pipe 2, also integrally can process with the first sleeve pipe 1 and the second sleeve pipe 2.
For the ease of hand-held, easy to operate, preferably, first handle 11 is dual-lug type handle, and second handle 21 is draw-ring type handle.
In order to the better effects if making blocking-up ring 31 tighten up, preferably, as shown in Figures 2 and 3, an end cap 12 is set in the front end of the first sleeve pipe 1, end cap 12 is provided with for the through hole through blocking-up ring 31, and the diameter of through hole is less than first set bore.
In order to make haemostatic effect better; and better protection hepatic portal enters liver blood vessel 4; preferably; blocking unit is banded; there is the band shape of appropriate width; the contact surface blocking ring 31 and hepatic portal vein 4 can be increased, and hepatic portal can not be scratched because of meticulous enter liver blood vessel 4 or other internal organs, and blocking-up ring 31 shape can be made more stable.Blocking unit will have suitable elastic force, makes blocking-up ring 31 shape of formation more stable, and preferably, the material selection of blocking unit has suitable elastic silica gel or medical macromolecular materials.
Conveniently regulate and maintain block ring 31 tighten up degree, preferably, as shown in Figure 1 and Figure 4, in the first sleeve pipe 1 rearward position, the screwed hole (not shown) through one-sided casing wall is set, and the screw 13 to close with corresponding threaded holes, the relative position of the first sleeve pipe 1 and the second sleeve pipe 2 is controlled by the precession degree of depth of turning adjusting screw 13, thus block ring 31 be adjusted to suitable tighten up degree after, what maintain blocking-up ring 31 tightens up state, by adjustment screw 13, facilitate the switching of hepatic portal occlusion and blood supply state in hepatotomy operation process.
When not using, the second sleeve pipe 2 is sheathed in the first sleeve pipe 1, and blocking-up ring is accommodated in the first sleeve pipe 1 or slightly exposed portion is outside the first sleeve pipe 1, and screw 13 is tightening state, is against on the second sleeve pipe 2, fixes the relative position of the first sleeve pipe 1 and the second sleeve pipe 2.
During use, the front end of Porta hepatis blocker is penetrated into corresponding position in human body by puncture casing, then adjustment screw 13, second sleeve pipe 2 and the first sleeve pipe 1 can be moved axially relatively, second sleeve pipe 2 is inwardly promoted, blocking-up ring 31 is made to stretch out the first sleeve pipe 1, then hepatic portal being entered liver blood vessel 4 puts in blocking-up ring 31, this process sometimes instrument assisting in opening such as medical calm blocks ring 31, hepatic portal is entered liver blood vessel 4 to put into and block after ring 31, inside promotion first sleeve pipe 1, blocking-up ring 31 is received and enters first set pipe, blocking-up ring 31 is constantly tightened up, when tightening up correct position, screwing screw nail 13, fix the relative position of the first sleeve pipe 1 and the second sleeve pipe 2, make the maintenance of blocking-up ring 31 suitable tighten up degree, realize the hepatic portal when laparoscopic surgery hepatectomy and enter the blocking-up of liver blood vessel 4.
It should be noted that, this utility model arranges end cap 12 in the front end of the first sleeve pipe 1, only in order to the aperture of end is less than the internal diameter of the first sleeve pipe 1, thus make blocking-up ring 31 tighten up better effects if, this mode is only a kind of implementation, concrete, also can be that the endoporus of the first sleeve pipe is shoulder hole, the aperture of front end is less than the aperture of rear end, thus realizes better tightening up effect to blocking-up ring 31.
In sum, Control of Hemorrhage in Laparoscopic Liver door block device of the present utility model, comprise the first sleeve pipe, the second sleeve pipe, connection plug and blocking-up ring, connection plug is sheathed in the second sleeve pipe, block ring by connection plug and second telescopic joint, and stretch out the second sleeve pipe, second casing pipe sleeve is located in the first sleeve pipe, blocks outside extended first sleeve pipe of ring, by regulating the relative position of the first sleeve pipe and the second sleeve pipe, tighten up blocking-up ring, realize when laparoscopic surgery, vascular inflow occlusion enters hepatic blood flow, reduces liver parenchyma hemorrhage from disconnected process, and structure is simple, easy to operate.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail this utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of this utility model.
