Problems solved by technology
[0004] At present, the puncture holders on the market have no restrictions on the position of the needle entry end and the position of the separation operation hand. If the position of the needle entry end or separation operation hand is close to the patient's body, there may be insufficient operating space when using it. , is not conducive to the doctor's puncture operation

Embodiment Construction
[0047] figure 1 It is a schematic diagram of the assembly of the puncture support and the ultrasonic probe provided by the embodiment of the present invention; figure 2 It is a schematic diagram of needle insertion when using the puncture support provided by the embodiment of the present invention; image 3 It is a schematic view of needle release when the puncture stent provided by the embodiment of the present invention is used. Such as figure 1 As shown, before the puncture operation, the puncture support 100 needs to be connected with the ultrasonic probe 200 to form an integrated body, and the needle outlet end of the puncture support 100 is located on the same side as the detection end of the ultrasonic probe 200 . Such as figure 2 As shown, when performing the needle insertion operation, the puncture needle 300 selects the corresponding introduction port (that is, selects the needle insertion angle), and then penetrates into the patient's body along the needle inse...

The invention relates to the technical field of puncture equipment, and in particular relates to a needle frame structure and a puncture support. The needle frame structure comprises an angle controlplate, a needle groove plate and a locking device; the needle groove plate comprises a plurality of semi-open needle inlet channels, the angle control plate and the needle groove plate are attached toform a closed needle inlet channel, the first end of the needle inlet channel is a guide-in opening of the needle body, the second end of the needle inlet channel is a guide-out opening of the needlebody, and the end where the guide-in opening is located is a needle inlet end; the locking device comprises a first clamping part and a second clamping part, the first clamping part is rotationally connected with the angle control plate, and the second clamping part is fixedly connected with the needle groove plate; and the first clamping part comprises a driving hand position, the driving hand position is located at the needle inlet end of the angle control panel, the first clamping part can move between a first position and a second position by pulling the driving hand position, and therefore clamping and separating of the first clamping part and the second clamping part are achieved. According to the scheme provided by the invention, an operation space as large as possible is reservedfor puncture operation and needle frame structure separation operation.
Description
technical field [0001] The invention relates to the technical field of puncture equipment, in particular to a needle holder structure and a puncture bracket. Background technique [0002] Ultrasound interventional surgery is a new technology developed on the basis of ultrasound images. During the operation, it is necessary to install an ultrasound probe puncture support on the ultrasound probe, and then perform puncture under the precise guidance of the ultrasound probe puncture support. The puncture needle can reach the lesion directly. Surgical operations such as suction, drug administration, and catheterization can be performed, or fine treatment operations such as microwave, radio frequency, and laser energy can be given. Interventional ultrasound surgery is different from traditional surgery in that it does not require surgery and only needs a fine needle puncture. The patient suffers less pain and does not need to be hospitalized. It is relatively safe, easy to operate...
