Abstract
The utility model discloses a hepatoduodenal ligament interrupter which comprises clamp arms, clamp holders integrally connected with the clamp arms, and a clamp shaft for realizing movable connection between the two clamp arms and the clamp holders 1; the main point of the hepatoduodenal ligament interrupter is that: said clamp arms are of a thin flat arc structure with excellent elasticity; a cog slot is reserved in a cambered surface at an inside of the clamp arms; protrusions are disposed inside the clamp holders 1; and a spring is disposed between the two protrusions. The hepatoduodenal ligament interrupter has the advantages of rational structure, novel structure and convenient use and can well avoid injury of blood vessels and bile ducts in liver operations, thereby reducing complicating diseases and improving safety of hepatoduodenal ligament interruption.
Description
Affiliated technical field
This utility model relates to technical field of medical instruments, is specifically to be used for the utensil that blood flow is blocked in the hepatoduodenal ligament in a kind of operation on liver.
Background technology
The hepatoduodenal ligament blocking-up is the means of often using in the operation on liver.In the prior art, during the blocking-up of row hepatoduodenal ligament, adopt rubber tube binding compressing method usually.The dynamics that this method not only bundlees pressurization is difficult for controlling, but also diminishes the danger of ID blood vessel of impairing the liver and bile duct.
Summary of the invention
In order to solve the deficiency of operating theater instruments in the existing hepatoduodenal ligament blocking-up, it is a kind of simple to operate that this utility model provides, and can avoid blood vessel and bile duct injury, reduces the liver 12 intestinal ligament block devices of complication.
The technical scheme that its technical problem that solves this utility model adopts is: this hepatoduodenal ligament block device, comprise jig arm 6, and the clamp holder 1 that links into an integrated entity of jig arm 6 and make the folder axle 4 that flexibly connects between two jig arm 6 and the clamp holder 1, mainly be that said jig arm 6 is for having the thin flat arc structure of favorable elasticity, the cambered surface of jig arm 6 inboards is provided with teeth groove 5, clamp holder 1 inboard is provided with between 2, two knuckles 2 of knuckle and is provided with spring 3.
This utility model advantage compared with prior art, mainly be reasonable in design, novel structure, easy to use, can avoid blood vessel and bile duct injury well in the operation, reduce complication, improved the safety of hepatoduodenal ligament blocking-up.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. clamp holder, 2. knuckle, 3. spring, 4. folder axle, 5. teeth groove, 6. jig arm.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is described in detail:
As shown in Figure 1, this hepatoduodenal ligament block device, comprise jig arm 6, and the clamp holder 1 that links into an integrated entity of jig arm 6 and make the folder axle 4 that flexibly connects between two jig arm 6 and the clamp holder 1, mainly be that said jig arm 6 is for having the thin flat arc structure of favorable elasticity, the cambered surface of jig arm 6 inboards is provided with teeth groove 5, clamp holder 1 inboard is provided with between 2, two knuckles 2 of knuckle and is provided with spring 3.
During use, select firmly to push clamp holder 1 with thumb and forefinger, the spring 3 that clamp holder is 1 is compressed, and the jig arm 6 of far-end is opened.Select the blocking position of hepatoduodenal ligament, open jig arm is aimed at this position after, the finger that comes up, this moment, spring stretched, the jig arm of far-end is closed also pushes liver 12 and refers to ligaments, reaches the purpose of the interior blood flow of blocking-up hepatoduodenal ligament.Reuse thumb and forefinger extruding clamp holder just can remove on hepatoduodenal ligament after jig arm is opened after blocking-up was finished.
