Description
The cross reference of related application
The application requires in the priority of the 60/811st, No. 376 U.S. Provisional Patent Application of submission on June 6th, 2006 according to 35 U.S.C. § 119 (e), and its full content is incorporated this paper by reference into.
Technical field
The present invention relates generally to the existence or the nonexistence of the object that is marked with responder are detected, for example, in operation process, the operation object is detected.
Background technology
Existence or the nonexistence that can determine object often are useful or important.For example, before finishing, operation determines that whether the object relevant with operation is present in patient's body is vital.These objects can be different forms.For example, can be operating theater instruments, as dissecting knife, scissors, tweezers, mosquito forceps and/or clip.Again for example, can be relevant auxiliary material and/or disposable, as surgical sponge, gauze and/or mat.Can not locate these objects before the patient is sewed up may need to carry out extra operation, and may produce the medical consequences with serious harm in some cases.The danger of infection be may increase like this, extra pain of patient and psychentonia caused simultaneously.
Acceptable detection and the step of removing foreign body comprise the object that uses in the operation are counted in the operation.X ray detects and also can be used to locate foreign body.Yet, often incorrect to the counting of object.And, even the x ray detection also has defective.Although in fact as the object of operation sponge kind, embedded the opaque material of x ray so that its easier detection, but the operation sponge often is squeezed into very little area in vivo, thereby the x ray always can not make these objects luminous and obtain detecting effectively.And, worstly be, owing to need film to dash volume (rolling up) even fast film dashes, so the x ray is a kind of detection method of time delay.The patient obtains expression patient foreign body in vivo position through being everlasting x ray result has just sewed up before fully.Therefore, detect to postpone to cause needs of patients to operate on operation again, thereby increased the probability of postoperative complication.
The prior art (except that the x ray analysis) that foreign body detects is generally also very expensive, can not use well (promptly to such an extent as to the checkout equipment volume that relates to is too huge, they often hinder the use of wanting localized object), perhaps can not provide effective detection fully.Exemplary technology comprises labelling or the tag system that adopts radioactive, electromagnetic, magnetic force or dynamo-electric detection technique.The more detailed argumentation of these existing known technologies is partly provided in the background technology of the 6th, 026, No. 818 United States Patent (USP)s of the inventor, and the full text of this patent is incorporated this paper by reference into.
In theory, the electronic positioning unit detection of sponge that should be suitable for performing the operation.Practical situation is under the cost of economy, to be difficult to make small-sized flag member to have enough signal intensitys and carry out reliable detection.The increase of flag member size may cause harmful consequence in the use of wanting inspected object.For example, the operation sponge is a kind ofly wished detected common objects, is applied owing to it can be out of shape.Yet distortion usually makes large-scale flag member distortion, and enough signal intensitys that small-sized flag member can not be provided for detecting.Indeformable large-scale flag member will largely reduce the availability through the sponge of just using after the distortion.The previous patent of the present inventor is discussed in greater detail in conjunction with existing known arrangement.Operation object as sponge kind should be deformable to adapt to the working region of body cavity.If flag member or responder are compressed and are packed and make it have enough little resistance to deformation zone in sponge, it then can use under the situation that does not hinder the sponge function.Yet when the area of described tag device or responder dwindles, connection will reduce, and almost be sightless thereby make it for the typical detection system that expectation is used to perform the operation.Some hospitals have formulated rules, comprise inventory or require to carry out repeatedly count with in operation to object use and withdrawal is followed the tracks of.
This manual method efficient is not high, needs cost professional's time, and is easy to make mistakes.Another method adopts responder and wireless should the inquiry and detection system.This method is with on the different article of wireless answering attached to use in the operation.Should ask with detection system and comprise the detector that the transmitter of transmitted pulse broadband wireless signal (for example radio frequency or microwave frequency) and the wireless signal that responder is returned in response to the pulse broadband signal of emission detect.Advantageously, this automated system has reduced professional and needed time of other staff when increasing accuracy rate well.The embodiment of this method has been discussed in the 6th, 026, No. 818 United States Patent (USP)s submitting on February 22nd, 2000 and No. 2004/0250819 United States Patent (USP) of December in 2004 disclosed US on the 16th.
Although detector can detect the wireless signal that returned by responder and the relative position of responder, responder need carry out the artificial removal in patient's body.Therefore, must set up with responder visual and get in touch so that in time responder and the operation object that adheres to are successfully removed.Yet,, need spended time to set up and get in touch with the visual of responder in case responder has by mistake been stayed in patient's body with the operation articles that adheres to.
And transmitter can be taked the form of hand-holding rod (wand).In use, whether the surgical site that contiguous patient body was handed and be positioned to rod by the surgical staff of just finishing operation detects wireless answering and also stays in the body with the operation object that adheres to.In use, being close to operative site and medical worker may cause antibacterial or courses of infection at the hand-held rod in back that the patient is undergone surgery to rod near the patient.Therefore, reusable rod may be the carrier of antibacterial or pathogenic bacteria, and these antibacterials or pathogenic bacteria may be infected other will carry out the patient that responder detects.
Therefore, expectation obtains a kind of responder and rod that can solve or overcome at least a portion the problems referred to above.
