Abstract
The utility model relates to a portal blood blocker in laparoscopic hepatectomy comprising an outer thimble and an inner cannula, which is characterized in that the inner cannula is sheathed in the outer thimble, the outer thimble is provided with locking device of the inner cannula, the front end of the inner cannula is provieded with a wire circle for tying the ligation strip, and the front end of the outer thimble is sheathed with a flexional tube. When hepatectomy is performed, the portal blood blocker enters abdominal cavity through the laparoscopic puncture clamp, the tube replacing the finger of the doctor passes through the right or the left incision of the hepatoduodenal ligament rounding the hepatoduodenal ligament, and sends the pre-placed ligation strip in the tube to the opposite side, then tightly ligates the hepatoduodenal ligament to block hepatic portal blood flow. The utility model has the advantages of small external diameter, easily entry into abdominal cavity through laparoscopic working pipe, no need of another large incision for sending devices to abdominal cavity, in particular to the application of minimally invasive hepatectomy.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, portal blood blocker under the chamber mirror that especially a kind of operation on liver uses.
Background technology
Liver cuts operation, in order to prevent to bleed profusely in the art, needs the vascular inflow occlusion blood flow.In conventional laparotomy, the hepatic portal bloodstream blocking is to pass the hepatoduodenal ligament rear with finger, is with urinary catheter, sebific duct or shoestring, around the back tension of one to two week of hepatoduodenal ligament, fixes with the mosquito forceps clamp, reaches the purpose of hepatic portal bloodstream blocking.Along with applying of Minimally Invasive Surgery, operation on liver can carry out under peritoneoscope, but owing under peritoneoscope, undergo surgery, need not carry out routine and open abdomen, therefore can't use conventional wearing around bandage vascular inflow occlusion blood flow, and also find no the apparatus that is specifically designed to the hepatic portal bloodstream blocking at present with finger.
Summary of the invention
In order to solve the problem that does not have special apparatus vascular inflow occlusion blood flow in the abdominal cavity arthroscopic diagnosis at present, this utility model provides portal blood blocker under the mirror of a kind of chamber, and this block device not only structure is simple especially, easy and simple to handle, and does not need big otch to open abdomen.
The technical scheme that its technical problem that solves this utility model apparatus adopts is: portal blood blocker under the mirror of this chamber, comprise trocar sheath and inner sleeve, inner sleeve is socketed in the trocar sheath, trocar sheath is provided with the locking device of inner sleeve, the front end setting of inner sleeve is equipped with one and wears the iron wire loop that binds band, and the front end sleeve of trocar sheath is connected to one can crooked flexible pipe.During operation, this block device can enter intraperitoneal by peritoneoscope puncture card, the front end flexible pipe can be through hepatoduodenal ligament right border or left side hepatogastric ligament place otch, walk around hepatoduodenal ligament, deliver to offside with placing the ligation band (shoestring) in the flexible pipe in advance, under the chamber mirror guides, with matching used elastic separating plier or nipper under the peritoneoscope ferrule of ligation band (shoestring) free-end is taken out, back shrink back trocar sheath (together with flexible pipe) to the hepatoduodenal ligament front this moment, and the iron wire loop of inner sleeve front end exposed outside the flexible pipe, the ferrule of ligation band (shoestring) free-end that clips is passed iron wire loop, after entangling the ferrule of ligation band (shoestring) free-end, inner sleeve bounced back backward withdraw from.This moment iron wire loop will be in ligation band (shoestring) the indentation flexible pipe of hepatoduodenal ligament, the hepatoduodenal ligament circle is tight, push down by the retraction inner sleeve, reach the purpose of complete vascular inflow occlusion blood flow, provide nothing (lacking) hemal ring border for liver cuts.
The beneficial effects of the utility model are:
1, external diameter is little, and The book of Changes peritoneoscope working column enters the abdominal cavity, need not push toward intraperitoneal through in addition big otch.
2, block device front end flexible pipe is owing to have certain elasticity and toughness, after running into stomach wall, can turn, the ligation band (shoestring) that can replace the doctor to point ligation is used is delivered to offside, and can utilize flexible pipe that the hepatoduodenal ligament antetheca is compressed, neither damage the important blood vessels of pneumoretroperitoneum, do not weigh the pipeline in the hepatoduodenal ligament again wounded.
3, in the iron wire loop of block device inner sleeve front end ligation band (shoestring) end be tie a knot in advance fixing, the other end is free, after ligation band ferrule injects iron wire loop, be dragged into the flexible pipe internal fixation, operation finishes inner sleeve is pushed forward, appears iron wire loop, is easy to ligation band ferrule is taken out, the ligation hepatic portal of loosening, safely, save time, reliably, not damaged.
4, the block device inner sleeve can advance to go out the length that trocar sheath can prolong or shorten apparatus, both has been applicable to Most patients, is applicable to that again some healths are bigger, the patient of body cavity broad, and can be fixed on the extension position of any needs by locking device.
5, manufacturing process is simple, and is easy and simple to handle, cleans, sterilizes easily.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
In Fig. 1, portal blood blocker under this chamber mirror, comprise trocar sheath (3) and inner sleeve (2), trocar sheath (3) and inner sleeve (2) all adopt stainless steel material to make, inner sleeve (2) is socketed in the trocar sheath (3), be provided with a hold-down screw (6) in trocar sheath (3) rear end, be used to lock the position of inner sleeve (2), the front end setting of inner sleeve (2) is equipped with one and wears the iron wire loop (4) that binds band, its rear end is for ease of the spiral head (1) of operation, and the front end sleeve of trocar sheath (3) is connected to one can crooked rubber tube (5).
The preferred size of each parts of this portal blood blocker is as follows:
Inner sleeve: length=350mm, external diameter=5mm
Trocar sheath: length=200mm, external diameter=8mm
Rubber tube: length=150mm, external diameter=8mm
Spiral head: external diameter=30mm
Claims (2)
1. portal blood blocker under the chamber mirror, comprise trocar sheath (3) and inner sleeve (2), it is characterized in that inner sleeve (2) is socketed in the trocar sheath (3), trocar sheath (3) is provided with the locking device (6) of inner sleeve (2), the front end setting of inner sleeve (2) is equipped with one and wears the iron wire loop (4) that binds band, and the front end sleeve of trocar sheath (3) is connected to one can crooked flexible pipe (5).
