Description
Technical field
This utility model relates to fixture in a kind of art of puncture needle.
Background technology
Percutaneous biopsy: along with improving constantly of people's living standard, each tumor also more and more betides human body.In clinic diagnosis process, when the swollen properties of some tissues is failed to understand, inspection technology is got in many application punctures, carry out pathology qualitative, and then give further treatment, therefore Biopsy becomes some tissue tumor best approach qualitatively by obtaining suspect tissue to it.
To get inspection be very important a kind of invasive Clinics in present clinical diagnosis and treatment process in puncture, although can bring wound to patient, it is unquestionable to the importance of clinic diagnosis to get inspection, therefore at utmost to alleviate the injury of patient be that one necessarily requires.
In clinic diagnosis process, when can not determine its pathologic feature for suspicious lesions, normal employing medical image biopsy needle guide (ultrasonic, x-ray or the CT) suspicious lesions that punctures tissue, cuts a small amount of pathological tissues, determines lesion nature by pathological observation.
The confused class of present clinical biopsy needle is assorted many, but mostly all exists and get inspection cell body and amass little, and one-time puncture is got and examined the low shortcoming of success rate.Puncture needle comprises nook closing member, needle guard, also needs to be equipped with special puncture rifle simultaneously.
Get inspection process as follows:
1. puncture needle core, needle guard are correctly arranged on puncture rifle and puncture rifle is set in state to be excited.
2. guide location by medical image, determine that puncture needle enters suspicious lesions and organizes target area.
3. the target that punctures excites puncture rifle after determining.First puncture needle core enters pathological tissues, and parts of lesions tissue is in be got in inspection groove, and Puncture needle sleeve enters subsequently.In the process, the pathological tissues got in inspection groove cuts and overlaps to be stored in and gets in inspection groove by needle guard.
4. exit puncture needle, and get the pathological tissues in inspection groove.
Percutaneous puncture in treating art, percutaneous drainage, percutaneous puncture pain nerve retardance art all need CT and PET/CT location under the predetermined target spot of venipuncture, for guaranteeing safety, percutaneous puncture process all requires to take to monitor method of needle insertion in real time, or successively method of needle insertion inserting needle, because CT and PET/CT scanning all has radioactivity, real-time monitoring method of needle insertion makes surgical doctor, nurse suffers unnecessary radioactive ray dosage, mostly cancels.Mainly take at present successively method of needle insertion inserting needle puncture under CT and PET/CT Scan orientation.Puncture predetermined position skin and soft tissue first, needling length is shorter, need CT and PET/CT to scan and confirm tip position, but puncture needle cannot be fixed automatically, can be automatically crooked and topple over after leaving patient's hands, needle tip accurately cannot point to focus all the time, because patient in CT and PET/CT scanning process cannot hand-held pin all the time, otherwise can suffer excessive exposure.

Detailed description of the invention
Hereafter in conjunction with the accompanying drawings and embodiments this utility model is described further.
With reference to figure 1-5, fixture in a kind of art of puncture needle, comprising: the supporting mechanism 1 connected successively, guiding mechanism 2 and attitude reference device 3; Regulate the displacement of described attitude reference device 3 in X, Y, Z axis and direction by described guiding mechanism 2, make the body surface of itself and puncture needle subscribe position consistency; By attitude reference device 3 and supporting mechanism 1, described puncture needle is fixed on body surface and subscribes position.Go to observe the condition of whether accurately providing convenience site of puncture for doctor leaves sufferer.
Concrete structure is as follows:
Described attitude reference device 3 comprises two gripper clamps each and every one be parallel to each other 31, and by the principle of two one lines, puncture needle can be accurately fixed on current direction and deviation can not occur by a plurality of gripper clamp 31.Further, in order to prevent the excessive puncture needle that causes of the clamp down on power of gripper clamp to puncture needle from damaging, the jaw 311 of described gripper clamp 31 is provided with at least one resigning hole 312 in same position and forms biopsy needle by bit port.Make the size of bit port corresponding with the size of puncture needle, therefore puncture needle is placed in and allows in bit port, both can realize the location to puncture needle, and turn avoid puncture needle and be subject to excessive pressure.
Due in art, along with going deep into of puncture, the length that biopsy needle is exposed to outside patient is shorter and shorter, therefore, there is one can move along the orientation of gripper clamp 31 in described two gripper clamps be parallel to each other 31, thus adjust the length of described biopsy needle by bit port.Therefore, when operation proceeds to any stage, by adjusting the spacing of gripper clamp 31, can realize the clamping of puncture needle directed.
Due to the difference of site of puncture, the size of puncture needle is also different.Therefore, described resigning hole 312 is three, and aperture is different and corresponding with the biopsy needle of different size.So just can use by adaptive various puncture needle.
Described guiding mechanism 2 comprises the horizontal turning-bar 21, expansion link 22, vertical turning-bar 23 and the universal turning-bar 24 that connect successively; The end of described universal turning-bar 24 is connected with gripper clamp 31.
The end of described universal turning-bar 24 is parallel is provided with the connector 221 corresponding with described gripper clamp 31 number.So just can realize the dismounting of gripper clamp 31, the gripper clamp 31 different according to different surgical selection.In order to realize the adjustable interval between clamping 31, a direction that can arrange along connector 221 in described connector 221, is had at least to move.Described connector 221 is removably connected with the end of universal turning-bar 24, gripper clamp 31 respectively.Therefore, this connector 221 can be designed as disposable sanitary apparatus, ensure that the wholesomeness of operation.In the present embodiment, connector 221 is preferably alligator clamp.
In the present embodiment, horizontal turning-bar 21, expansion link 22, vertically turning-bar 23 and universal turning-bar 24 combined effect, just can realize the displacement of attitude reference device in X, Y, Z axis and direction can free adjustment.Described supporting mechanism 1 comprises the support bar 11 that one end is connected with described guiding mechanism 2 and the connecting device 12 being located at described support bar 11 other end, pass through connecting device, fixture in the art of whole puncture needle is connected with other supporter, thus it is fixing to achieve support.
Described connecting device 12 comprises two pieces of clamping plate be arranged in parallel 121, and a spacing adjusting device 122; Turn clockwise described spacing adjusting device 122 time, the spacing of described clamping plate 121 increases; When being rotated counterclockwise described spacing adjusting device 122, the spacing of described clamping plate 121 reduces.
The above; be only this utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that this utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
