Description
Technical field
The present invention relates to a kind of surgical retractor fixing device (surgical retractor fixingdevice), comprise: (a) cramping body, it is configured to surgical retractor fixing device is fixed on the support in detachable mode, described support extends and is configured to be suitable for being installed on the operating-table along the support longitudinal axis, (b) described rotary body is attached on the cramping body, (c) described rotary body can pivot around rotation axis, (d) described rotary body comprises retaining element, and described retaining element is arranged for the fixing operation retractor.According to second aspect, the present invention relates to a kind of under operative status the method for tractive structure.
Background technology
At first, operation retractor is limited as hand-held instruments, has the finger bar of a plurality of bendings, is used for keeping otch to open at operation process.Doctor or paraprofessional personnel hang over notching edge with the finger pike pole of operation retractor and apply tension force and open to keep otch, thereby provide the inlet that touches soma for the doctor.
In approximately recent two decades, operation retractor is developed into and is fixed on operating-table or other structure, is achieved so that retract, and does not need doctor or paraprofessional personnel always keeping retractor.
Generally speaking, the operating-table rail post is the base component of surgical retractor system.Rail post provides fixed structure for support and other hardware of attaching retractor equipment and other surgical apparatus.Retractor with different shape refers to that the retractor equipment miscellaneous of bar is used to operation, to help the doctor to keep operative incision to open or anatomical structure is moved apart its position.In general, present operational surgical retractor system adopts cam mechanism or interim spiral clamper with the various parts locks in place in the retractor systems.
Present operational surgical retractor system comprises round bar formula (round stock) retractor systems and flat (flat stock) retractor systems substantially.The limitation of flat retractor systems is, because the rectilinearity essence of each parts, these parts must be so that the right angle is interconnected in conjunction with realizing basically.Therefore, flat retractor systems can be assembled the orientation limited amount of realization.
Round bar formula retractor systems is in general welcome, this be because, round bar formula part in the system has toward each other in the other side and the ability of rotating with respect to hold assembly, thereby allows the various parts in the retractor systems interconnected with different angles miscellaneous.
Round bar formula retractor systems comprises various rod parts, and they initially link together by the spiral clamper.When using the spiral clamper, find the trend of spiral clamper by the cylindrical component distortion that causes retractor systems.In addition, the screw thread of spiral clamper trends towards wearing and tearing and lost efficacy.In addition, the assembling of each part in the retractor systems, location and interconnected requirement are used operator's both hands or even are added that paraprofessional personnel's both hands come package system.After after a while, be converted to cam lock or crossed the centre-lock connected system from spiral clamping connected system.
The cam lock system comprises two interconnected clampers substantially, and they are configured to grasp shaft-like retractor systems part, and the adjusting that can rotate relative to one another.Each clamper grasps a rod part.Two interconnected clampers by certain actuator for example the handle bar activated, actuator is locked in these two clampers on two shaft-like parts then, and locks two clampers simultaneously and relatively rotate with respect to each other to prevent them.A shortcoming of this configuration is, when clamper was released, they discharged fully and relatively rotate with respect to each other from two shaft-like parts simultaneously, and this just requires retractor systems being reorientated fully and aligning before the clamping again.
Surgical retractor system is used to handle biological tissue.When oversize, biological tissue may be impaired in the time of exerting pressure to biological tissue.Therefore, in the operation process that uses the mechanical type retractor, recommend retractor regularly unclamped or reduce tension force on the retractor, flow to the tissue that is pulled to allow blood, thus the histanoxia of preventing and possible necrocytosis.This just makes current retractor systems processing have beyond the aforementioned limitations, and the team that also will perform the operation places awkward condition.The operation drawing system can regularly unclamp in operation team, but next just requires to regulate each operation retractor fully so that it is reconnected.If but not like this, operation team might make biological tissue be pulled under tension force for a long time, thereby causes being pulled the danger of tissue damaged or necrocytosis.If it is consuming time or inconvenient readjusting, perhaps readjust the accurate positioning relation that will change anatomical structure, the Team Member that then the performs the operation line of generally being unwilling unclamps and readjusts retractor systems then.
Another problem that current round bar formula surgical retractor system produces comes from such fact, and promptly the doctor generally wishes retractor is located such that they can provide tractive tension force with an angle.The doctor likes this mode for outside the space that retractor can be moved to them and must work, thereby retractor can not disturb their action.When operation retractor is biased, often occur retractor is so located, promptly retractor is with respect to the complete straight line of the longitudinal axis of shaft-like part location.This causes applying and reversing or revolving force to being fixed on clamper on the cylindrical of drawing system or the rod part.This power trends towards causing that the clamper of drawing system slides around bar with the form of rotating.In order to tackle this problem, a kind of common way is to be applied to clamper on the shaft-like part with the mode tensioning that strengthens gradually.Regrettably, after tensile force had exceeded certain specified point, clamper trended towards causing keeping its rod part deformation and wearing and tearing, and this makes and more to be difficult to regulating system for use in afterwards process.
Another problem that the at present operational system that retracts exists is that when retractor was fixed in system by present clamper, the binding site between each parts was locked fully, thereby all was fixed on all are axial between the parts of combination.Usually, doctor or paraprofessional personnel need increase or readjust pull strength for specific activity.Regulate pull strength and mean that doctor or paraprofessional personnel loosen the clamper that is keeping retractor, reorientate retractor, apply clamper then again.Because the prior art clamper discharges fully and rotates simultaneously from two bars, therefore need two handss to align again at least and clamping system again.This may be the thing that bothers very much, because there is such time period, promptly the tension force on the retractor has reduced, and may move in bad mode and be organized under the state that tension force reduces.
Summary of the invention
