Abstract
The utility model discloses a releasable self-locking type hepatic portal blocking belt, which comprises a belt head part, a belt body part, a belt tail part, a convex tongue and a cog. The belt tail is of a triangular shape. The belt body is provided with a plurality of positioning holes which pass through the belt body and are uniformly continuously distributed at intervals. The belt head is provided with a position clipping hole which passes through the belt head. The belt body and the belt tail are permitted free penetration in the position clipping hole the inner wall of which is provided with the convex tongue. The convex tongue is provided with a cog which is perpendicular to the convex tongue. The cog matches the positioning holes. By equipping the convex tongue and the cog inside the position clipping hole, the utility model belt which can clip the positioning holes equipped on the belt body part achieves automatic releasing and locking functions. In this way, the operation efficiency can be improved. The releasable self-locking type hepatic portal blocking belt which is simple in structure and convenient in operation meanwhile can be formed by one-time stamping and repeatedly used.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, more particularly relates to a kind of band auto-lock function of vascular inflow occlusion blood vessel and the hepatic portal occlusion band easily of loosening.
Background technology
At present, go into liver blood stream blocked method and become minimizing and the most general method of control over bleeding in the liver surgery, have simple and practical characteristics, implement this method in the clinical position and normally use the tearing port of a latex tubing through hepatogastric ligament, tighten up in its front side intersection after walking around hepatoduodenal ligament, live with hepatic portal occlusion pincers (patent No. 200620157063.9) clamp then.But there is following shortcoming in this blocking-up method: 1, need to cooperate than big working place and many people, the operation open country appears, latex tubing tightens up and block the pincers clamp respectively needs a people to carry out; Bring secondary damage to surrounding organ when 2, the blocking-up pincers easily overturn liver as metallic weapon in operation.For overcoming above-mentioned deficiency, the disposable use hepatic portal occlusion of adjustable locking-type band (patent No.: 200920290565.2) and bow-tie hepatic portal occlusion device (patent No. 200720126277.4) a solution is provided respectively, but include a locking immobilising device, make complexity, complex operation.
Summary of the invention
In order to overcome the deficiency that existing hepatic portal occlusion band need be blocked the pincers clamp, easily cause pair to damage, this utility model provides a kind of self-locking hepatic portal occlusion band of loosening, by running through the screens hole of taking the lead taking the lead to be provided with, protruding tongue and fin are set in the screens hole, can block the locating hole that belt carcass partly is provided with, reach and loosen freely and the function of locking automatically.
This utility model specifically is achieved through the following technical solutions:
A kind of self-locking hepatic portal occlusion band of loosening, comprise take the lead, belt carcass and three parts of magnetic tape trailer, also comprise protruding tongue and fin, described magnetic tape trailer is triangular in shape; Described belt carcass is provided with several locating holes that runs through the even continuous distribution in interval of belt carcass; Describedly take the lead to be provided with one and run through the screens hole of taking the lead, described screens hole can hold described belt carcass and magnetic tape trailer freely penetrates; Described screens hole inwall is provided with protruding tongue, and described protruding tongue is provided with a fin perpendicular to protruding tongue, and described fin and described locating hole coincide mutually.
The free-end of described protruding tongue narrows down gradually;
Described magnetic tape trailer from belt carcass one end gradually attenuation narrow down.
The beneficial effects of the utility model are: simple in structure, easy to operate, simultaneously can a moulded section, and can use repeatedly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side-looking structural representation of protruding tongue and fin.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail.
Be illustrated in figure 1 as structural representation of the present utility model, a kind of self-locking hepatic portal occlusion band of loosening, comprise successively link to each other take the lead 1, belt carcass 2 and 3 three parts of magnetic tape trailer, described magnetic tape trailer 3 is triangular in shape, magnetic tape trailer 3 from belt carcass 2 one ends gradually attenuation narrow down; Described belt carcass 2 is provided with several locating holes 4 that runs through the even continuous distribution in interval of belt carcass 2, and locating hole 4 splits wide 2cm, and 1mm is uniformly distributed on the belt carcass 2 continuously at interval, and distribution is long to be 10cm; Described taking the lead 1 is provided with one and runs through the screens hole 5 of taking the lead, and described screens hole 5 can hold described belt carcass 2 and described magnetic tape trailer 3 freely penetrates; As shown in Figure 2, screens hole 5 inwalls are provided with protruding tongue 6, and the free-end of described protruding tongue 6 narrows down gradually; Described protruding tongue 6 is provided with a fin 7 perpendicular to protruding tongue 6, and described fin 7 coincide mutually with described locating hole 4, makes protruding tongue 6 after passing locating hole 4, and fin 7 can keep off in belt carcass 2 sides, prevents that belt carcass 2 slippages from loosening.
When using blocking-up band of the present utility model, during operation at the hepatogastric ligament opening, magnetic tape trailer 3 penetrated from the hepatoduodenal ligament rear side by opening part draw, insert screens hole 5 and also pass, progressively tighten up belt carcass 2 through the Wen hole, reach when estimating barrier effect, locating hole on the belt carcass 24 is set to fin 7 inboards on the protruding tongue 6, and protruding tongue 6 passes locating hole 4, and fin 7 blocks locating hole 4 simultaneously, can prevent that belt carcass 2 from loosening automatically, reach the vascular inflow occlusion and the purpose of locking voluntarily.When loosening hepatic portal occlusion locating hole 4 is crossed fin 7 from protruding tongue 6 and leave behind and get final product, belt carcass 2 is withdrawed from the screens hole 5 can take out the blocking-up band, very convenient and practical.
