Technical field
The present invention relates to a kind of puncture medical assistance instruments, and in particular to one kind can assist coaxial sleeve needle/puncture needle tune
The fixation device of whole angle.
Background technique
Percutaneous biopsy is clinically often used, it is will to puncture to be needled into target lesion in body cavity, by thin
The cutting of column or suction obtain a small amount of tissue, carry out pathologic finding, specify a kind of Clinics of lesion nature.And puncture institute
Pipe spreader needle/the puncture needle used has constant weight, and when inserting needle is shallower in puncture process or patient is thinner, muscle layer is relatively thin
When, coaxial sleeve/puncture needle can not be fixed by inserting needle direction, be easy to happen skew, cannot judge the pass of inserting needle direction and target spot
System, and then influence puncture procedure process.Even can not venipuncture when, have no alternative but to allow operator wear lead clothing closely hold needle into
Row CT scan resets, this process safety risk is larger.
In addition, doctor's hand operation needle angle will have error, slightly deviation may cause puncture needle to deviate target spot,
The number for increasing inserting needle, substantially increases the occurrence probability of complication, more serious security risk is caused to patient.
Summary of the invention
The object of the present invention is to provide the fixation devices that one kind can assist coaxial sleeve needle to adjust the angle, to make up existing skill
The deficiency of art.
In order to achieve the above objectives, the present invention take the specific technical proposal is:
A kind of fixation device for assisting coaxial sleeve needle to adjust the angle, which includes ring segment and disk, and the disk is buckled
Together on ring segment, the center of the disk is equipped with a slot, and slot long side center setting symmetry is consolidated
Determine card slot；It is set on the disk there are two symmetrical semicircle disk body, two semicircle disk bodies are divided into center slot
Two sides, two semicircle disk bodies are arranged in parallel and are each perpendicular to the disk；The disc centre sets a hollow needle
There are a pair of of fixing axle in column, the lower end of the hollow needle column, are stuck in the fixed card slot of slot, and hollow needle column upper end has one
To symmetrical short column, to be auxiliarily fixed, short column end pointer with a scale.
Further, the ring segment is equipped with angle index line.
Further, the disk is equipped with a pair of symmetrical pointer, is on same axis with the slot.
Further, the semicircle disk body is equipped with angle index line.
Further, the surrounding of the ring segment is additionally provided with patch, for sticking in body surface, thus fixed device.
The specific operation process of above-mentioned fixed device:
Thin-layer CT scanning is carried out before puncture, and three-dimensional reconstruction determines that the point of puncture A of body surface, the vertical body surface of target spot M, target spot are thrown
Shadow point M " measures the angle α and MA length L of MAM " in CT film first, and marks straight line A M " in body surface, and fixed device is sticked
It is attached on patient skin, centre bore (original state center needle column 5 is in Verticle disk 3) is overlapped with point of puncture A, establishes plane seat
Mark system, cephalocaudal axis y, vertical direction are x-axis, and rotating circular disk makes pointer 11 and AM ", two semicircle disk bodies on disk
Between slot be overlapped with A M "；Will coaxial sleeve needle be inserted into hollow needle column 5 in, adjust hollow needle column, opposite direction, i.e., to
Away from the direction of M ", 5 angle of hollow needle column is adjusted, its tuning drive gear 10 orientation angle α (i.e. coaxial sleeve needle and skin angle is made
Equal to α), along this direction depth of needle L, coaxial sleeve needle can smoothly be punctured in place along design angle depth.
The advantages of the present invention:
Structure of the invention setting is more ingenious, and structure is simple, and cost of manufacture is lower, and convenient to use, easy to spread.
Coaxial pilot pin/puncture needle easily can be fixed on body surface using the present apparatus；Help to operate doctor simultaneously with essence
Quasi- angle is punctured, and the successful probability of disposable puncture is increased, and reduces complication rate.The design of the present apparatus can also solve
The certainly tilt problem of puncture needle makes it be fixed on body surface along inserting needle direction by the requirement of operator；And the present apparatus is in fixed function
On the basis of increase angle adjustment device, help operates doctor and precisely holds needle angle, and it is successfully several to increase disposable puncture
Rate, to reduce the incidence of complication.
