Description
Technical field
The invention belongs to technical field of medical instruments, relate in particular to the employed a kind of mucosa traction apparatus that can control operating theater instruments position or attitude when endoscopic surgery.
Background technology
Endoscope is used to diagnose and the treat disease history in more than 50 year, be the endoscope of single clamp channel mostly, but continuous development and raising along with the endoscopic surgery technology, single apparatus can not satisfy the requirement of doctor to apparatus control, the urgent hope of doctor can simply utilize existing endoscope to realize the use that can cooperatively interact of two or more apparatuses, to adapt to complicated and highly difficult operation, make operation can saferly finish operation faster.
Scope great majority commonly used have only a duct to be used for leading to apparatus, in operation process, only use a hands in work as the people, lack corresponding cooperation, some complicated a little actions need be resolved into a lot of steps and finished, as peeling off, mucosa needs the operation of compound action, the threshold that has just increased operation is difficult for promoting, and operating time is very long to have increased misery to patient.At present the two pincers road endoscope that can lead to two apparatuses is simultaneously arranged also but its cost is higher, hospital has quantity seldom, has only the minority large hospital to have, small-middle hospital not universal highly difficultly be difficult to promote at small-middle hospital with complex endoscopic procedure.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this invention is to provide a kind of mucosa traction apparatus, not only can simply be assembled into existing endoscope distal end can install or current passage for operating theater instruments to increase by one, and by this apparatus can also control other operating theater instruments with respect to the position of endoscope or attitude so that operation technique, so just can satisfy the demand that the doctor is used many apparatuses, operation can be safer, easy, can shorten the operation time spent greatly, reduce patient's misery.
To achieve the above object, the present invention has adopted following technical scheme:
A kind of mucosa traction apparatus comprises:
