Description

A kind of controllable gasbag-type Flexible ureteroscope guide sheath
Technical field
The present invention relates to a kind of guide sheath, specifically a kind of controllable gasbag-type Flexible ureteroscope guide sheath belongs to urine output Pipe soft lens rubble operation applied technical field.
Background technique
With the continuous development of endoscopic technique, Flexible ureteroscope rubble is increasingly becoming kidney stone, proximal ureteral calculus Preferred therapeutic modality.
However clinically, it has been found that the success rate that a phase is placed in ureter guide sheath is lower, and reason may be with patient The factors such as ureterostenosis or existing ureter guide sheath material are hard, diameter is wide are related;But often have again among this kind of patient Major part is can to pass through the thin mirror of ureter or standard mirror, illustrates that its ureter condition is fine;When clinically encountering one Phase is placed in the patient of ureter guide sheath difficulty, and surgical doctor often selects first indwelling Ureteral stent tube (F6 Doubles cather) Expand ureter, half a month or January Hou Zaifan institute tube drawing, set sheath and further lithotripsy in treatment, hospitalisation for surgery can be obviously increased in this way Number increases medical expense;In addition, ureter guide sheath is past during merging because material is hard, diameter is fixed at present Different degrees of damage is caused to ureter toward meeting, in some instances it may even be possible to cause ureter avulsion, ureter fracture possible, long term is also It can lead to the increase of ureterostenosis risk.Therefore, a kind of controllable gasbag-type Flexible ureteroscope guiding is proposed regarding to the issue above Sheath.
Summary of the invention
It is lower it is an object of the present invention to solve ureter guide sheath merging success rate in the prior art, and be easy to cause not With the defect of degree injury of ureter, the present invention provides a kind of controllable gasbag-type Flexible ureteroscope guide sheath.
A kind of controllable gasbag-type Flexible ureteroscope guide sheath, including air bag sheath, seal wire, gas-guide tube and the inflation of miniature constant pressure Pump;
The air bag sheath is made of outer layer and internal layer, is formed with closed gap between outer layer and internal layer, closed gap with lead Tracheae connection, air bag sheath are made of rubber material, with inflated for deflated and then expansion or can shrink;The seal wire of front end softness is arranged It is intracavitary in internal layer formation, and inner cavity is stretched out at both ends, the front end of seal wire is fixed on air bag sheath;The end of gas-guide tube is arranged There is miniature constant pressure inflator pump.
Further, the expanded in diameter for inflating rear interior cavity is 0.5~0.8cm, and internal layer is attached on seal wire after deflation.
Further, outer layer is made of elastic rubber material, and internal layer is made of non-resilient rubber, internal layer and outer layer after inflation Between formed 0.09~0.11cm closed gap.Outer layer has elasticity, and in on-inflatable, outer layer shrinks and includes internal layer, patch It is attached on seal wire, the form of the next small size of on-inflatable can be maintained, can expand and separate with internal layer again after inflation;And internal layer does not have It is flexible, to can guarantee that inner cavity has stable a form and diameter.
Further, between the internal layer and outer layer the closed gap of shape cross section be in cirque structure, internal layer with Several draught lines that are isometric, being placed equidistant with are provided between outer layer.Draught line inflation when from stable air bag sheath form work With so that air bag sheath is in the hollow tubular structure that inflated condition is in same diameter.
Further, gas-guide tube is fixed on one end on outer layer far from seal wire front end, is equipped with constant pressure on the gas-guide tube Valve.
Further, the length of men's type air bag sheath is 450mm ± 50mm, the length of lady's type air bag sheath be 350mm ± 30mm。
Further, the outer layer outer surface is equipped with paraffin coating, and paraffin coating is uniformly attached to superficies.
Further, the seal wire front end is made of soft silica gel material.
Further, the miniature constant pressure inflator pump can be such that air bag sheath homogenous charge expands, while can be according to operation need It asks, air bag sheath inner diameter size is adjusted by control pressure.
Further, seal wire front end is provided with the bayonet that can be fixed with internal layer, and internal layer can be separated from bayonet after inflation Come, air bag sheath can be fixed or be separated with seal wire by bayonet.
The beneficial effects of the present invention are:
1. this kind of controllable gasbag-type Flexible ureteroscope guide sheath structure is simple, novel in design, can be in non-inflated state Under entered in ureter with small size (with the similar size of common seal wire), can sufficiently expand ureter again after inflation, manufacture peace Full operative space solves one phase of ureter guide sheath merging difficult problem, and sheath success rate is set in raising, while being reduced ureter and being led Draw the damage during sheath is placed in ureter, it also can reach the effect etc. at expansion ureterostenosis, achieve many things at one stroke.
2. when in use, convenient for can be on the basis that urine output tube airbag sheath is sufficiently expanded to the lesser ureteral calculi in part On, it directly takes out, while abundant dilating effect can be played to ureterostenosis section and whole ureter, production cost is low, ties Structure is simple, practical value is higher, is suitble to promote the use of.
