Abstract
The utility model provides a duodenum mirror with protection of disposable consumptive material, used repeatedly's duodenum mirror is protected to the disposable consumptive material for the, has realized that one person no. 1 of duodenum mirror trades, has avoided cross infection, has solved the not thorough problem of disinfection. The end cap is transparent elastomer, and the long opening in side is sealed with soft interface, and soft interface is hourglass hopper -shaped, and is makeed by the elasticity film, soft interface macrostoma end outer fringe is pasted on end cap long opening edge, and soft interface osculum pot head clamps deferent distal end pipe wall certain distance department once only, once only clamping the deferent near -end and being coniform or globular sealing, it is crooked that the distal end is certain angle, lifting pincers ware head and being equipped with the pulley, the pulley periphery has corresponding radial recess, and the steel wire distal end that the pincers ware was lifted in the pulling is as lifting the coupling spindle of pincers ware with the pulley.
Description
Technical field
The invention belongs to medical instruments field, be specifically related to medical endoscope.
Background technology
Duodenoscope is widely used in the Clinics and Practices of liver, gallbladder, pancreas systemic disease.Especially be a uniqueness of duodenoscope and current irreplaceable pancreatic duct inspection method for endoscopic retrograde cholangiopancreatography (ERCP) (ERCP) art, being the important means of Diagnosing Biliary Tract Carcinoma disease, is an important component part in minimally invasive surgery.But sterilization safety problem but perplexs this endoscope always, owing to limiting by image core prototype part optical pickocff CCD and material of main part, the mode sterilizations such as unavailable High Temperature High Pressure, sterilization means are few, and the not thorough problem of ubiquity sterilization.And the duodenoscope that the present invention relates to due to its functional structure all complicated than other endoscope structure, so there is larger sterilization risk.
Prevent cross infection way the most reliably by comprehensive for endoscope cladding applications with medical disposable material, the present inventor had once invented endoscope's disposable protective jacket (patent No.: ZL201032668.8 with regard to gastrointestinal fujinon electronic video endoscope, US8241208B2), all use medical disposable material coated by every for endoscope from the inside to surface with body cavity bioresorbable part, but duodenoscope comparatively gastrointestinal electronics endoscope structure is complicated, needs to further improve structures such as end caps on the disposable protecting jacket structure basis of gastrointestinal fujinon electronic video endoscope.
Summary of the invention
With the duodenoscope of medical disposable material protection, its ultimate principle is to endoscope's full protection that can not stand autoclave sterilization process with primary sterilization consumptive material, its all isolation by consumptive material with patient's body lumen bioresorbable part is covered, substantially realize the disposable application of duodenoscope, solve it in thorough the do not occurred cross infection problem of clinical middle sterilization.
Technical solution of the present invention is as follows:
With a kind of disposable consumptive material, nonexpondable duodenoscope improved is protected, make it not contaminated in clinical.With the duodenoscope of medical disposable material protection; the insertion section outer surface cuff film coated of its mirror body; disposable pincers deferent is inserted in mirror body corresponding pipeline; mirror body far-end has end cap to cover; disposable pincers deferent in the disposable cuff of external for mirror and mirror body pipeline is connected as a single entity by end cap, thus can protect the outer surface of duodenoscope and inner surface of pipeline.End cap is made by transparent elastic material, end cap side is provided with the strip opening consistent with mirror body cephalic par opening shape, a soft interface is established in strip opening, soft interface is funnel-form, have big opening end and osculum end, and made by elastic film, soft interface big opening end outer rim is bonded on end cap strip edge of opening, osculum end is enclosed within disposable pincers deferent far-end tube wall certain length place, and bonding with disposable pincers deferent; Disposable pincers deferent near-end carries out coniform or spherical closing, and is convenient to insert to mirror body pipeline and have pollutant to enter in pipe before preventing use.
Duodenoscope improves as follows: clamp device head and be also provided with pulley lifting, peripheral pulley has the groove of relevant radii; The steel wire far-end lifting pincers device is pulled to connect with the axle of pulley.
The present invention changes the disinfection way of duodenoscope, and during endoscopy, whole consumptive material one people one changes, and avoids cross infection, substantially realizes the disposable effect of duodenoscope, thoroughly solves the sterilization difficulty that duodenoscope exists.

Detailed description of the invention
The present invention is made up of two parts, and a part is through the duodenoscope of transformation, and another part is medical disposable material, and nonexpondable duodenoscope medical disposable material protects not contaminated by it.Medical disposable material not only has cuff and end cap protection duodenoscope outer surface, and one more pincers deferent is placed in protection duodenoscope inner surface in mirror body pipeline, and both are connected as a single entity by end cap, and duodenoscope has been carried out general protection from the inside to surface.
First, following improvement is carried out to duodenoscope: as shown in Figure 1, pincers device 1.2 head of lifting of duodenoscope is also provided with a pulley 1.4, peripheral pulley has the groove 1.5 of relevant radii, pull the steel wire far-end 1.3 lifting pincers device to connect with the axle of pulley 1.4, this pulley can reduce the frictional force of lifting the motion of pincers device.
In addition, disposable consumptive material comprises: end cap 2, cuff 3, disposable pincers deferent 4.Wherein end cap 2 is enclosed within mirror body cephalic par 1.1, is connected as a single entity with the disposable pincers deferent 4 in the cuff 3 of coated mirror body insertion section outer surface and mirror body pipeline, thus can protect the outer surface of duodenoscope mirror body 1 and inner surface of pipeline.
As shown in Figure 2, end cap 2 entirety is transparent elastic material, and end cap side is provided with the strip opening 2.1 consistent with mirror body cephalic par opening shape, is provided with soft interface 5 in strip opening, this soft interface 5 is made for elastic film and is funnel-form, has big opening end 5.1 and osculum end 5.2.Soft interface big opening end 5.1 outer rim and end cap strip opening inner side adhering and sealing, soft interface osculum end 5.2 is enclosed within disposable pincers deferent 4 far-end outer wall a distance and bonding (Fig. 3).
As shown in Fig. 4, Fig. 5, when lifting pincers device and wire drawing and being in relaxation state, lift and clamp device and disposable pincers deferent does not interact, biopsy forceps is stretched out from strip opening is oblique by disposable pincers deferent; Lift when tension wire drawing makes to lift pincers device, soft interface produces corresponding deformation, promotes disposable pincers deferent and lifts, the sensing of Indirect method biopsy forceps, thus carry out pincers extract operation to specific part across soft interface.
Disposable pincers deferent 4 far-end has certain angle to bend, carry out before near-end 4.1 does not use coniform or spherical closed (Fig. 6), its far-end stretches into from end cap strip opening 2.1, then inserts soft interface osculum end, its sweep to enter completely in interface and the mouth of pipe towards big opening end.Disposable pincers deferent near-end be coniform or spherical close be convenient to mirror body pipeline inserts and prevent use before have pollutant to enter in pipe.
