Abstract
The utility model relates to a detachable expansion saccule with a connector and relates to a medical instrument apparatus for operation channel expansion and providing a maintaining function in surgical operations. The detachable expansion saccule with the connector is characterized by safety, reliability, simple structure and rational price. The detachable expansion saccule with the connector can be used while matched with a trocar. The detachable expansion saccule with the connector is formed by a saccule body and the connector, wherein the saccule body is connected with the connector; the inner wall of the saccule body is provided with a reinforcing rib; the saccule body is single-layered or multi-layered; when the saccule is multi-layered, the external layer can act as a redundant protective layer if the innermost layer saccule body is accidently scratched and the saccule body is cracked; the connector is a hollow column and comprises a thinnest end and a thickest end; the diameter of the thickest end is larger than the diameter of a head sheathing canal of the trocar; the connector can be an elastic body or an inelastic body; and when the connector is the inelastic body, the external surface of a connection part between the connector and the trocar is banded tightly via an external ring.
Description
Technical field
What the detachable expansion sacculus of this utility model band union joint related to is a kind of medical device for operation path expansion, maintenance function in surgical operation.
Background technology
In current surgical operation, in order to obtain good surgical field of view and operating environment in operation, generally use carbon dioxide pneumoperitoneum to do passage expansion, but for the relatively narrow tissue site of close structure, tract, carbon dioxide pneumoperitoneum can not reach good expansion effect, at this moment often carry out predilation with special extension fixture, modal is the predilation that carries out operation path with dilating sacculus.
The sacculus using is at present made by oneself by doctor conventionally, common way be by medical gloves tighten on flexible catheter.Sacculus enters after human body by conduit may according to circumstances be expanded to 200ml-500ml to sacculus water-filling or inflatable dilatation to 500ml-1000ml(child), maintaining 3-5min fully expands gap, slowly after draining, take out sacculus, then insert puncture casing (torcar) and carry out other operations.
Use medical gloves Self-made air sac device cannot guarantee on the one hand aseptic, have for patients larger infection risk; On the other hand, the sacculus that medical gloves is made in use, often bursts under the effect of pressure, brings puzzlement to operative doctor.
Because Self-made air sac device exists that manufacturing process is loaded down with trivial details, the shortcoming such as fully sterilizing, quality be unreliable, therefore need a kind of product that can overcome above-mentioned shortcoming to meet clinical demand.
Summary of the invention
This utility model provides a kind of detachable sacculus with union joint for above-mentioned deficiency, can be used in conjunction with puncture casing (trocar).There is feature safe and reliable, simple for structure, reasonable price.
The detachable sacculus of this utility model band union joint takes following technical scheme to realize:
Detachable sacculus with union joint is made up of utricule and union joint, and utricule is connected with union joint.
Described utricule is spherosome or oval ball or other obform body.
Described utricule adopts elastomeric material or non-resilient shrinkable material.
Described elastomeric material adopts rubber, silica gel, latex, polrvinyl chloride etc.
Described non-resilient shrinkable material adopts PVC thin film, polyurethane film etc.
When described utricule adopts non-resilient shrinkable material, can need to produce according to operation the utricule of given shape, be convenient to obtain comparatively suitable operation path.
Described utricule inwall can be provided with reinforcement.
Described utricule is one or more layers; In the time adopting multilamellar utricule, if being scratched accidentally, innermost layer utricule causes utricule explosion, can serve as redundancy protecting layer by skin.
Described union joint is open column shape, comprises taper end and butt end, and the diameter of butt end is greater than the diameter of puncture casing (trocar) head sheath pipe.
Described union joint is elastic component, or non-resilient; When union joint adopts non-resilient time, when use, at union joint and puncture casing (trocar) junction outer surface with outer ring banding; Described union joint is closely connected with puncture casing, avoids gas leakage, is convenient to plug simultaneously, facilitates operation process.
When use, can directly the union joint of sacculus be socketed in to the head of puncture casing (trocar), sacculus and puncture casing (trocar) are connected.
Accompanying drawing explanation
Below with reference to accompanying drawing, the utility model is described in further detail
Fig. 1 is the detachable balloon structure schematic diagram of this utility model band union joint.
Fig. 2 is the extension fixture structural representation in conjunction with this utility model structure.
In figure: 1, sacculus, 2, puncture casing, 3, dioxide bottle, 4, endoscope, 5, connection tube;
1-1, utricule, 1-2, union joint.
The specific embodiment
With reference to Fig. 1, the detachable sacculus 1 of this utility model band union joint is made up of utricule 1-1 and union joint 1-2, and utricule 1-1 is connected with union joint 1-2.
Described utricule 1-1 is spherosome or oval ball or other obform body.
Described utricule 1-1 adopts elastomeric material or non-resilient shrinkable material.
Described elastomeric material adopts rubber, silica gel, latex, polrvinyl chloride etc.
Described non-resilient shrinkable material adopts PVC thin film, polyurethane film etc.
When described utricule 1-1 adopts non-resilient shrinkable material, can need to produce according to operation the sacculus of given shape, be convenient to obtain comparatively suitable operation path.
Described utricule 1-1 inwall can be provided with reinforcement.
Described utricule 1-1 is one or more layers; In the time adopting multilamellar utricule, if being scratched accidentally, innermost layer utricule causes utricule 1-1 explosion, can serve as redundancy protecting layer by skin.
Described union joint 1-2 is open column shape, comprises taper end and butt end, and the diameter of butt end is greater than the diameter of puncture casing (trocar) 2 head sheath pipes.
Described union joint 1-2 is elastic component, or non-resilient; When union joint 1-2 adopts non-resilient time, when use, at union joint 1-2 and puncture casing (trocar) 2 junction outer surfaces with outer ring banding; Described union joint 1-2 is closely connected with puncture casing 2, avoids gas leakage, is convenient to plug simultaneously, facilitates operation process.
When detachable expansion sacculus with union joint uses, the union joint 1-2 of sacculus 1 is connected with puncture casing 2, use connection tube 5 that the inflatable interface of puncture casing (trocar) 2 is connected with medical dioxide bottle 3, open gas cylinder valve, carbon dioxide enters sacculus 1 through puncture casing 2, and sacculus 1 starts to expand.
In gas replenishment process, endoscope 4 is inserted to puncture casing 2, whether the tract of observing sacculus 1 expansion formation is satisfied with; Continue inflation, until the tract that expansion forms size is satisfied; Closing carbon dioxide gas cylinder 3 valves, make sacculus 1 keep full 3-5min, and tract is fully expanded; Pull out the connection tube 5 of gas cylinder, slowly emit the carbon dioxide in sacculus 1, extract sacculus 1, predilation completes.
If adopt the mode of fluid injection to make sacculus 1 carry out expanse, can be connected a water-sealed drainage bottle between dioxide bottle 3 and puncture casing 2.
