Description
Technical field
The present invention relates to medical equipment field, in particularly a kind of surgical procedure can with control device curvature, surround
Target blood carries out blood flow control, adjustable air bag is locked after tightening up blood vessel, needle body and elastic strip engagement flex, be simple in construction,
The vascular flow control device of controllable curvature easy to use, damage is small.
Background technology
In surgical procedures, when being handled for blood flow than more rich tissue and organ, to avoid operating
Massive Bleeding in journey, it can often use and reduce tissue blood supply by controlling the method for the blood flow of Major Vessels, so as to reduce to mesh
Mark the risk of Massive Bleeding in tissue, organ processing procedure.Such as in hepatotomy operation, it can often pass through vascular inflow occlusion blood vessel blood
Stream reduces the bleeding risk of hepatotomy process.The way clinically commonly used now is will to need to control the blood vessel of blood flow to pass through
A flexible line is wrapped into target blood after surgical anatomic exposure, by tighten line come target blood is carried out pressure so as to
Control vascular flow；Another method is to carry out clamp to target blood by haemostatic clamp, so as to control blood flow.
Following deficiency be present in the operation of blood vessels present blood flow control：1st, either with line or clamp, this is grasped under hysteroscope
Make process because the limitation of courses of action becomes more difficult, this also constrains many and there may be the operation of massive haemorrhage in hysteroscope
Lower completion smoothly, safe；2nd, the operation of clamp control blood flow may cause damage to blood vessel, thereby increases and it is possible to not reach effective control
The purpose of blood flow processed；3rd, clamp head does not have enough curvatures, can not carry out clamp, and curvature mistake to special target blood
Greatly, its application under hysteroscope can not be limited by hysteroscope handle hole again.4th, target blood needs are wrapped to reach line under hysteroscope
The operation of multi-step is carried out, increased operation difficulty and risk, limits application of the operation under hysteroscope.
For the existing operating technology for carrying out target blood blood flow control, need that target blood can be surround and to blood vessel
The device to be pressed, particularly meet the operation servicing unit of hysteroscope operating condition limitation.Needing can in a kind of surgical procedure
Blood flow control is carried out with control device curvature, around target blood, adjustable air bag tighten up blood vessel, needle body and elastic strip coordinate it is curved
Locking, the vascular flow control device of controllable curvature simple in construction, easy to use, damage is small after song.
The content of the invention
It is an object of the invention to provide can carry out blood flow with control device curvature, around target blood in a kind of surgical procedure
