Abstract

The utility model relates to a positioning guiding apparatus which can ensure that surgical apparatus accurately puncture to reach the position in one time in an operation of puncturing at the deep part of the viscera of the body. The guiding apparatus for positioning of puncturing at the deep part of the body, which mainly comprises a guide tube, a holding shelf, a bracket and a fixed seat, can cooperate with tomography illustration of an x-ray machine to make operators succeed to puncture in one time in the operation of puncturing at the deep part. The utility model has the advantages of simple structure and convenient operation. The guiding apparatus for positioning of puncturing at the deep part of the body not only can reduce manual injure and excessive bleeding of the punctured position due to repeated puncturing, but also can reduce the x-ray exposure of patients and operators.

Description

Guiding apparatus for positioning of puncture at the deep part of the body

This utility model relates to a kind of device of human internal organ being done the bathystixis operation.Be specifically related to the accurate positioning and guiding of a kind of help puncture operation technique person, guarantee accurately the puncture locating guide device of one-time-reach-place of operating theater instruments.

Human internal organ is made puncture fistula-building, is a new surgical procedures method growing up of the seventies in the world.Can lay the fistulation pipe by fistulation, carry out intracavity inspection and operation, make patient avoid the hardship of open surgery.Because the opening operation of puncture operation right and wrong, the operation technique person can't be thrust operating theater instruments exactly intracavity intuitively and arrive predeterminated target.Whether though all adopt the method for unidirectional or two-way X line radiography demonstration at present in the world at operative site, with the position of definite intracavity target, operation is still carried out under non-intuitive manner, need operator's direction that judgement is punctured with feel by rule of thumb to aim at the mark.Therefore the puncture operation needs the operator to have certain experience and technology, even a skilled expert also is difficult to guarantee a thorn and success.And if repeated localised puncture causes the damage of being worn internal organs and too much hemorrhage etc. not enough easily; In addition, also can be owing to the operating time is long, operating process needs to carry out under the supervision that X line radiography shows, makes patient and operator be subjected to the irradiation of too much X line and brings adverse consequences.

The purpose of this utility model provides a kind of device of positioning and guiding, guarantees the one-time success rate when the operation technique person does the puncture operation, to solve the deficiency of above-mentioned prior art.

This utility model is achieved in that with a long guide pipe fixed clamp of 5----15CM on the holding frame of adjusting angle arbitrarily according to the various outer diameter of puncture needle, to be furnished with the guide pipe of all size, so that the selecting for use of different requirements of operation.For the ease of transposing guide pipe and convenient sterilizing, guide pipe clamping easily and dismounting.But holding frame is installed in three-dimensional and adjusts arbitrarily on the support of position, and support is installed in the holder, this utility model can be fixedly mounted on the frame of operation table corresponding site by holder.Be the principle that is projected as a point according to straight line and light with the square while, cooperate X line machine, the angle of coarse adjustment holding frame, make the axial and center position basically identical to the X line of guide pipe, regulate support then, from three-dimensional mobile guide pipe, further finely tune the holding frame angle simultaneously, make guide pipe on the radiography display screen, become a ringlet, and dark thorn target is placed within the ringlet, and then making guide pipe near support bracket fastened each point of adjustment behind patient's body surface, this moment, patient's body surface point of puncture and puncture direction were determined by guide pipe, as long as puncture needle is thrust body cavity in guide pipe, the target radiography is shown with X line machine from other direction again, observe the degree of depth that puncture needle thrusts,, guarantee the one-time success rate of degree of depth puncture operation until arriving predeterminated target.

The utility model will be further described below in conjunction with accompanying drawing.

Accompanying drawing is a structural representation of the present utility model.

With reference to accompanying drawing, this utility model is made up of guide pipe 1, holding frame 2, support 3 and holder 4; Guide pipe 1 usefulness bolting is clamped on the holding frame 2 that can adjust angle arbitrarily, holding frame 2 is installed in and can adjusts on the support 3 of position arbitrarily from three-dimensional, and support 3 can be fixedly mounted on this utility model on the frame of operation table corresponding site by holder 4.HX902 type lithotrite is an operation table that has two-way X line location concurrently and be furnished with removable bed surface.Be example now with the HX902 machine, this utility model is fixedly mounted on the middle part frame of operation table, earlier the patient who lies on the operation table is stung the target radiography deeply, and target is placed on the focus of two-way X line, the angle of coarse adjustment holding frame 2, make a guide pipe and a center position basically identical to the X line, regulate support then, from three-dimensional mobile guide pipe, further finely tune the holding frame angle simultaneously, make guide pipe on the radiography display screen, become a ringlet, and dark thorn target is placed within the ringlet, and then making guide pipe near support bracket fastened each point of adjustment behind patient's body surface, it is fixing that guide pipe is finished.Puncture needle is inserted guide pipe, and penetrate body cavity, when being worn internal organs near quilt, make patient keep air-breathing motionless, insert target with puncture needle this moment under another radiography to the X line is observed, and puncture is success once.Take out the pin stamen, insert guide wire, can begin the operation that needs.

This utility model is simple in structure, and is easy to operate, can greatly improve and guarantee the one-time successful puncture rate of bathystixis fistulation operation, thereby reduces operation technique person's roentgen radiation x amount, has application prospect widely.

Claims

1, a kind of human body bathystixis positioning and guiding instrument is characterized in that it is made up of guide pipe 1, holding frame 2, support 3 and holder; Guide pipe 1 fixed clamp and can be dismantled and clamping on the holding frame 2 that can adjust angle arbitrarily easily; Holding frame 2 is installed in and can adjusts arbitrarily on the support 3 of position from three-dimensional, and support 3 can be fixedly mounted on the frame of operation table corresponding site by holder.
