Abstract
The utility model relates to a tie hepatic portal blocker for blocking the blood flow at the hepatic portal in partial hepatectomy, which consists of an elliptical column tube-shaped sleeve, an elliptical column-shaped column insertion pole and a line strip. One end of the column insertion pole is sheathed in the sleeve and can moves along the axial direction of the sleeve, a spring is pressing arranged between the sleeve and the column insertion pole, the side walls of two wide surfaces of the sleeve are symmetrically and respectively provided with a line strip penetration hole, another line strip penetration hole is arranged on the column insertion pole, the line strip can sequentially pass through the line strip penetration holes of the two components, when the two components carry out the forward motion to a certain position under the external force, the line strip penetration holes thereon are mutually closed, the line strip can be moved conveniently in the holes, when the external force is removed, the line strip penetration holes on the two components are mutually dislocated, and the line strip is clamped and fixed. The product has the advantages of simple and novel structure, compact and delicate model, convenient operation, least effort, easy cleaning and disinfection, good working stability and so on, which can also effectively improve the efficiency of partial hepatectomy and ensure operation effects.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates to the hepatic portal occlusion device that is used for vascular inflow occlusion portion blood flow in a kind of operation on liver.
Background technology
The liver ablation is the method for the optimum or malignant tumor of treatment liver at present commonly used, and vascular inflow occlusion portion blood flow, to reduce intraoperative hemorrhage then be perform the operation successful crucial behave of decision.The mode that adopts for vascular inflow occlusion portion blood flow in clinic operation was in the past: the single line band is walked around hepatic portal portion, steel wire hook of reuse is after one section plastic cement pipe passes, hook goes out this tape, clamps tape with strength with vascular forceps then, blocks the blood flow through hepatic portal portion whereby.But this mode is the also corresponding deficiencies such as inconvenient operation, effort, functional reliability difference that have in concrete the execution, have reduced surgical effect to a certain extent.
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and then a kind of novelty simple in structure, easy to operate, job stability and good reliability is provided, can guarantees surgical effect and alleviates the bow-tie hepatic portal occlusion device of medical worker's labor intensity.
Be used to realize that the technical solution of foregoing invention purpose is such: this bow-tie hepatic portal occlusion device is by sleeve pipe, inserting column bar and single line band are formed, wherein, said sleeve pipe is a single-ended occluded ellipse stylostome, said inserting column bar is oval column rod member, its end is sleeved in the sleeve pipe and can moves axially along sleeve pipe, between sleeve pipe and inserting column bar, press and be equipped with a spring, respectively have a tape perforation in telescopic two wide side-walls symmetries, on the bar wall of inserting column bar, have a tape perforation, said tape can pass in the tape perforation by two members successively, when sleeve pipe and inserting column bar under external force during move toward one another to a fixed position, tape perforation on it is involutory mutually, tape can conveniently move in the hole, after external force is removed, tape perforation mutual dislocation under the effect of inner spring power on two members is fixedly clamped tape.When this block device is used in the Rhizoma Atractylodis Macrocephalae, with tape around hepatic portal after one week, earlier after pass in the tape of opening on sleeve pipe and the inserting column bar perforation, clutch the two ends of block device with hands, after making the tape perforation of sleeve pipe and inserting column bar involutory mutually block device is pushed ahead, treat to unclamp finger after hepatic portal portion blood flow is blocked, tape will be stuck because of the elastic reset of spring, then tape will be fixed on this position, vascular inflow occlusion portion blood flow with being stabilized; Use the two ends of clutching block device after finishing again also it oppositely to be pulled back,, and then taken out smoothly so tape will be released because of the spring contraction.
Compared with prior art, the utlity model has novelty simple in structure, the small and exquisite exquisiteness of moulding, easy to operate, laborsaving, be convenient to advantages such as cleaning and sterilizing, good operating stability, can effectively improve the efficient of liver part resection operation, guarantee surgical effect.
Description of drawings
Fig. 1 is the wide cross-sectional view to side of this block device.
Fig. 2 is that the A-A of Fig. 1 is to structural representation.
The specific embodiment
As shown in the figure, the construction profile of bow-tie hepatic portal occlusion device described in the utility model such as same small and exquisite cassette knot, it is formed by mutually nestable sleeve pipe 1, inserting column bar 3 with from the tape 4 that the two part body passes.Sleeve pipe 1 is the stainless steel cylindroid shape pipe of a single-ended sealing, and inserting column bar 3 is that one one end is sleeved on the oval column rod member of Stainless Steel system in the sleeve pipe 1, and horizontal between sleeve pipe 1 and inserting column bar 3 have a spring 2.Two wide side-walls symmetries at sleeve pipe 1 respectively have a tape perforation 1a who supplies tape 4 to penetrate and pass, correspondingly on the bar wall of inserting column bar 3 also have one and penetrate the tape perforation 3a that passes for tape 4, the tapes perforation of two places 1a, 3a can involutory (or staggering) when applying (or not applying) external force situation.In addition, be provided with the inner shield ring platform at the pipe edgewise of sleeve pipe 1, the two leptoprosopy side place symmetries that stretch into sleeve pipe 1 rod end at inserting column bar 3 respectively are provided with a retaining salient point, can stop inserting column bar 3 to be deviate from by sleeve pipe 1.Sleeve pipe 1 and inserting column bar 3 opposite external side all inwardly slightly cave in, and are provided with the granulous point of some sand on concave face.The person grips with handled easily.
In the actual fabrication structure, when sleeve pipe 1 and inserting column bar 3 be nested with in place after, the length of this block device is 2.0cm～2.5cm, the outer wide footpath of sleeve pipe 1 is 1.0cm～2.5cm, outer narrow footpath is 0.5cm～0.8cm, and tape 4 is about and is 30cm, respectively is surrounded by the long quoit of 1cm at the two ends of tape 4, be convenient to tape and from aperture, pass, and be beneficial to the fluoroscopic machine searching.
