Description
Technical field
The utility model relates to medical instrument, especially a kind of CT and MR guiding puncture biopsy positioning device.
Background technique
CT and MR guided percutaneous needle biopsy is that one kind passes through each position interest lesion target lesion of whole body under CT and MR guiding
Skin puncture obtains Pathologic specimen and finally obtains the Non-vascularized iliac bone technology of pathological diagnosis.Because the clear lesions showed of CT and MR energy is big
Small, form, position, downright bad hole area can be explicitly shown and close on the good anatomy relationship of blood vessel, nerve etc., therefore can accurately really
Determine inserting needle position, angle and depth, avoid damage to blood vessel, nerve and spinal cord etc., to substantially increase the safety of interventional procedure
Property, success rate and pathology accuracy rate.Advantage is: method is easy, and small to tissue damage, bleeding is few, safer, infection chance
It is few, it can be carried out under local anaesthesia in outpatient service, nor affect on early treatment.Current aspiration biopsy is living using the puncture of CT and MR
Inspection is all made of transversal scanning, and longitudinal axis scribing line uses hand operation, needs Multiple-Scan to verify in art, the selection and puncture of puncture
Carry out be confined to patient's experience, operating time is long, punctures that deviation is larger, and repeated puncture time rate is higher, and has certain bleeding
Even fatal complication.How accurately simple positioning is carried out to aspiration biopsy target lesion, becomes and be difficult to solve for a long time
Technical problem.
In view of the foregoing, a kind of CT and MR guiding puncture biopsy positioning device is now developed.
Utility model content
The purpose of this utility model is to overcome deficiencies in the prior art, provide a kind of CT and MR guiding puncture biopsy
Positioning device, the contrast agent for the rectangle structure that S-shaped is continuously constituted in image documentation equipment transversal scanning laser rays and angiography catheter or
Pure water right-angled intersection, the crosspoint that can easily find laser positioning line and angiography catheter is pre- site of puncture, dilutes radiography in pipeline
Anchor point caused by agent or pure water does not have artifact, keeps site of puncture cleaner, and structure is simple, is skillfully constructed, manufacturing cost
Cheap, using effect is significant, compact structure spirit jade for asking rain, easy to carry.
The utility model to achieve the goals above, adopts the following technical scheme that a kind of CT and MR guiding puncture biopsy is fixed
Position device is made of: inner cover, outer cover, resilient support cushion block, angiography catheter, transitional connection pipe, sealing chock；Inner cover and outer
Lid is vertically arranged side plate by the edge of rectangular slab and constitutes, and makes between inner cover and outer cover after inner cover and the corresponding fastening of outer cover
Constitute closed cavity, the rectangular angiography catheter that setting S-shaped is continuously constituted in closed cavity, surrounding in inner cover or outer cover and
Four resilient support cushion blocks are set between the surrounding of angiography catheter, angiography catheter is made to be fixed on the closed cavity of inner cover and outer cover
Interior, the both ends setting that the rectangular angiography catheter that S-shaped is continuously constituted is corresponded on inner cover, outer cover and resilient support cushion block is reserved
Hole, preformed hole is interior to be arranged transitional connection pipe, the inner end of the input end of angiography catheter or outlet end insertion transitional connection pipe, transition company
The preformed hole of inner cover and outer cover is exposed in the outer end setting sealing chock of adapter tube, the outer end for sealing chock, and S-shaped is continuously constituted rectangular
S-shaped is constituted in the angiography catheter of shape, and continuously rectangular contrast agent or pure water fill cavity.
Rectangular angiography catheter, inner cover, the outer cover that the S-shaped is continuously constituted are all made of transparent soft plastic material or silicon
Glue.
The resilient support cushion block uses section for the strip rubber block of rectangle.
The sealing chock uses rubber chock.
The inner cover and outer cover use detachable fastening structure, convenient for dismantling.
The diameter in the section of the contrast agent or pure water filling cavity is 0.8~1.2mm.
The outer surface of the inner cover and outer cover is respectively provided with sterile pad pasting.
Beneficial effect when in use, the sealing-plug for the rectangular angiography catheter input end for needing first continuously to constitute S-shaped
Block pulls out, and diluted CT contrast agent or pure water are injected in angiography catheter, then the sealing chock plug of angiography catheter input end is real
Sealing.Contrast agent or pure water in angiography catheter show the rectangle structure that S-shaped is continuously constituted, before use, first will be outside inner cover
The sterile pad pasting on surface is thrown off, then will integrally be sticked to the check point skin surface sterilized, finally throws off outer exterior surface
Sterile pad pasting, the contrast agent for the rectangle structure that S-shaped is continuously constituted in image documentation equipment transversal scanning laser rays and angiography catheter or
Pure water right-angled intersection, the crosspoint that can easily find laser positioning line and angiography catheter is pre- site of puncture.
The present apparatus is close with skin attachement, and patient's locator after breathing and involuntary movement is avoided to move；It is sterile
Pad pasting is more cleaned using the area Shi Shu, and is conducive to puncture the closure and hemostasis of needle track；Contrast agent or pure water institute are diluted in pipeline
The anchor point of generation does not have artifact, and due to no metal fittings, the present apparatus is also applicable to MR Needle localization.
The utility model keeps site of puncture cleaner, and structure is simple, is skillfully constructed, and manufacturing cost is cheap, using effect
Significantly, compact structure spirit jade for asking rain, easy to carry, this product has obtained the one of school expert and many patients since coming into operation
Favorable comment is caused, popularity application is suitble to.
