Abstract
The utility model relates to a locking device for a porta hepatic blood flow blocking strap. By using the locking device, hepatic inflow vessels are blocked during hepatobiliary surgery. The locking device for the porta hepatic blood flow blocking strap comprises a locking piece, wherein a square through hole is formed in the locking piece; two latex ribbons penetrate in the square through hole in parallel; a screw opening I is upwards formed in the middle of the through hole perpendicularly; a corresponding screw is formed in the screw opening I; a screw opening II is formed above the screw opening I; the screw opening I and the screw opening II are concentric; and the diameter of the screw opening II is greater than that of the screw opening I; a sleeve sleeves the screw opening II in a threaded manner; a screwdriver can penetrate in a middle hole of the sleeve; and a key pattern which is matched with a screwdriver bit is formed on the top of the screwdriver. The locking device for the porta hepatic blood flow blocking strap has the advantages that the locking device is simple in structure, is safe and reliable, occupies small space, and is particularly suitable to be matched with the latex ribbons; and secondary injury on neighbor organs and retinal tissues in an operation process can be avoided.
Description
Technical field
This utility model relates to a kind of surgical operating instrument field, relate in particular to a kind of while carrying out hepatobiliary surgery for blocking the pringle maneuver locking device into hepatic blood flow.
Background technology
Liver ablation is the method for the optimum or malignant tumor of at present conventional treatment liver, and vascular inflow occlusion blood flow, to reduce intraoperative hemorrhage be the key that determines successful surgery.In clinical, normally use the tearing port of a latex tubing through hepatogastric ligament, after walking around hepatoduodenal ligament, intersect and tighten up in its front side, then clamp with hilus hepatis blocks pincerses or block with locking hasp, this method needs certain working place, barrier effect is relevant to the level of skill of operative doctor, intersects that tighten up may be because tractive brings damage to blood vessel and bile duct, in addition in the process of latex tubing, overturn liver in operation time, metal pliers brings secondary damage may to surrounding organ and omental organization.Existing multinomial patented technology report adopts from the band tightening up, and because these designs one are that to have lock tooth two be to adopt there is no elastic resin material, in snare or traction process, will, to injuries of tissues and organs, bring operation risk.Meanwhile, also there is complex structure in said apparatus, high to processing technology requirement, the problem that cost is larger.So it is safer that hepatectomy generally still adopts latex tubing bundle cover at present.
Utility model content
The purpose of this utility model is the defect that overcomes prior art, provides a kind of simple in structure, safe and reliable, occupies the less a kind of pringle maneuver locking device in space, is particularly suitable for latex tubing band.
This utility model solves the technical scheme that its technical problem adopts: a kind of pringle maneuver locking device, comprise locking member, on locking member, have for two latex bands parallel through square perforation, perforation middle part has screw-socket I vertically upward, in screw-socket I, there is corresponding screw, screw-socket I has the screw-socket II that mutually concentric with it diameter is larger above, has sleeve silk knot mutually on screw-socket II, and sleeve mesopore can pass for screwdriver; The key flower type matching with the screw edge of a knife is arranged at screw top.
Particularly, the fit key of described screwdriver and screw flower type is that cross-shaped is more practical.
Described locking member surface is rounding off.
Whether in use procedure, first latex tubing is walked around and tied up organ, then relatively penetrate the perforation of this device, then tension, tightens latex circle by holding screw, can sleeve need to be laid down according to operation.As lay down sleeve, and in the screw of loosening, the sleeve of can first screwing on, then screwdriver is imported into and unloads screw from sleeve, also can directly unload screw with screwdriver.Visible, the effect of sleeve is convenient operation.Lay down sleeve and can save a lot of operative spaces.
Effect of the present utility model is: simple in structure, safe and reliable, occupy space less, and be particularly suitable for matching with latex tubing band.Avoid in operating process the pair damage bringing to surrounding organ and omental organization.
Brief description of the drawings
Fig. 1 is this utility model assembling local section diagrammatic cross-sectional view;
Fig. 2 is that sketch is amplified in the side-looking of locking member in Fig. 1.
In figure, 1. latex tubing, 2. latex tubing drawing head, 3. screw, 4. locking member, 5. sleeve, 6. screwdriver, 7. screwdriver handle, 8. perforation.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail: a kind of pringle maneuver locking device, comprise locking member 4, on locking member 4, have for two latex bands parallel through square perforation 8,8 middle parts of boring a hole have screw-socket I vertically upward, in screw-socket I, there is corresponding screw 3, screw-socket I has the screw-socket II that mutually concentric with it diameter is larger above, has sleeve 5 silk knot mutually on screw-socket II, and sleeve 5 mesopores can pass for screwdriver; The cross-shaped matching with the screw edge of a knife is arranged at screw top.Described locking member surface is rounding off, in order to avoid damage body tissue.
