Description
Technical field
The present invention relates to a kind of tissue retractor, in particular to a kind of tissue retractor for endoscopic surgery.
Background technique
Endoscope was born over more than 50 years, experienced the stage from medical diagnosis on disease to disease treatment, to some digestive diseases
Treatment is largely effective and reliable, or even as the preferred therapy of some diseases.In recent years, with endoscopic biopsy art, EMR
The development of (endoscopic mucosal resection art), ESD (decollement under endoscopic mucosal) technology, it is interior in terms of gastrointestinal polyps and early cancer
Treating under mirror already becomes preferred diagnosis and treatment means, especially plays key effect in the discovery, diagnosis and excision of early cancer.Mesh
Before have been developed that some endoscopic special equipments, however, operation difficulty is relatively compared with other Endoscopic Treatment technologies
Greatly.
In ESD surgical procedure, it with the progress of operation, usually will appear the case where tissue is stayed, stay tissue and seriously affect
Surgical field of view interferes the accuracy of surgery location.Existing operating method is to pass through hyaline cap in scope front end additional transparent cap
It is supported to tissue is stayed, clearly shows the visual field to obtain, high frequency cutting tool is then directed at submucosa, carry out
Subsequent procedures operation;However, scope front end additional transparent cap will cause the diminution of scope holistic vision, accidentally grasped in art in order to prevent
Make, continuous forward and back scope is needed to confirm position, meanwhile, during ESD, additional hyaline cap front end is easy hydrops, opponent
There is serious influence in the art visual field, needs I & A repeatedly that could continue to perform the operation, although existing hyaline cap technology has gone out
Now with drainage side opening or groove, but clinical effectiveness and bad.
Summary of the invention
Goal of the invention: the purpose of the present invention is to provide a kind of tissue retractors, and the tissue retractor is easy to use, can
Effectively tissue is stayed in support, provides good surgical field of view for performer.
Technical solution: a kind of tissue retractor of the present invention, including the outer tube and middle pipe being mutually arranged, in this in pipe
It is equipped with interior bar, outside the extended middle pipe in the front-end and back-end of the interior bar;The front end of the interior bar, which is connected with, struts component, the support
Rod unit includes strutting arm along the flexibility of the circumferentially-spaced distribution of middle pipe, and any flexibility struts the front end of arm and interior bar front end is fixed,
Rear end is connected with elastic ring, and the middle part which struts arm is fixedly connected by support arm with middle pipe front end;It is soft under original state
Property strut arm and fit with middle pipe outer wall, post-tensioning interior bar, interior bar is dropped back relative to middle pipe, and support arm support flexibility struts arm expansion
And support big elastic ring;It is pushed forward interior bar, flexibility struts arm and restPoses.
Wherein, the outer tube back-end is arranged with grasping member.
Preferably, the middle pipe rear end cap is equipped with push handle.
Furthermore the interior rod rear end is equipped with pull ring.
Further, the support arm includes the first connecting rod and second connecting rod being hinged, the front end of the first connecting rod with
Flexibility struts to be connected in the middle part of arm, and the rear end of second connecting rod is connected with middle pipe front end.
Preferably, the section of the elastic ring is round or banding pattern.
The utility model has the advantages that compared with prior art, remarkable advantage of the invention is: after tissue retractor of the invention passes through
Interior bar is drawn, interior bar is dropped back relative to middle pipe, and support arm support flexibility struts arm and is unfolded and supports big elastic ring, utilizes elastic ring and exhibition
The flexibility opened, which struts the fixed support intestinal wall of arm, prevents tissue from staying, and does not influence while providing good surgical field of view to performer interior
The observation of sight glass, surgery location controllable precise;Be pushed forward interior bar, flexibility strut arm be bonded again in pipe front end, hydrops will not be generated,
Avoid influence of the hydrops to surgical field of view;In addition, tissue retractor structure of the invention is simple, and it is easy to use, it can drop significantly
Low operating difficulty shortens operating time, to reduce operation risk.
