Description

A kind of CT Guided Percutaneous Transthoracic Needle Aspiration Biopsies breathe positioner

Technical field

A kind of medical auxiliary apparatus are the utility model is related to, are specifically that a kind of CT Guided Percutaneous Transthoracic Needle Aspiration Biopsies breathing is fixed Position device.

Background technology

With industrial development, environmental pollution getting worse, while aging of population, respiratory disease becomes influences people People's health principal element, particularly lung cancer morbidity rate rise year by year, some patients with lung cancer have been middle and advanced stages when finding, lose root Chance is controlled, therefore is early diagnosed extremely critical；But some lesion lists can not be obtained from image and Sputum culturing, bronchoscopy Accurate Diagnosis is, it is necessary to histopathological diagnosis, and conventional method is by opening the work of chest biopsy or B ultrasound Guided Percutaneous Transthoracic Needle Aspiration Biopsy Art, although the former obtains, tissue specimen is big, and wound is big, costly；The latter, which can only be directed to, is located at subpleural lesion, is applicable in few Some patientss, CT guided biopsies are a kind of Minimal Invasive Biopsy technologies for developing rapidly and promoting in recent years, domestic at present Outer technique is quite ripe.

The Lesions that Pulmonary nodular lesion core is located at lung peripheral region, close pleura or the wall of the chest are more difficult, utilize CT Guided Percutaneous Transthoracic Needle Aspiration Biopsies art can carry out lump clinical etiologic diagnosis, formulate therapeutic scheme and prognosis；Institute before puncture There is patient to make conventional Enhanced CT, it is preoperative to look into bleeding and cotting time and platelet count etc.；Stringent screening idicatio, contraindication, Puncture is made to determine；CT guided biopsies are preoperative and Intraoperative position is successful surgery key, general using training patient To hold one's breath and body surface coral column positioning mode, the domestic provincial Grade A hospital of small part introduces external auxiliary system laser positioning using external, The equipment price is expensive, Difficulty, using twice sweep in art, is operated after whether evaluation breathing is consistent, and be divided to two Footwork carries out inserting needle, increases inserting needle accuracy and biopsy success rate, mentions breathing whether unanimously carry out two in technical operation twice Secondary scanning, but be difficult often to judge thorax fluctuating by naked eyes whether unanimously to judge before and after breathing in real work, patient Itself feel to be also unmanageable, particularly under tense situation, frequently encounter that control of breathing is bad to cause lung in clinical position Inner disease foci is shifted, it is necessary to reposition multiple scanning and puncture again, the generation of pneumothorax complication is greatly increased, so as to cause to perform the operation Risk of failure；In clinical position, the reason for puncture failure is most direct be exactly patient respiratory coordinate it is bad, when lesion is less than<3cm is then Easily influenced by breathing, special two lobi inferiors lesion because diaphram participate in breathing up and down shift range it is big, therefore two lower lung lesions by Breathing influences maximum；It is domestic at present for control of breathing is punctured still in the subjective judgement stage, without objective evaluation standard, it is necessary to Design and a kind of energy accurate judgement of research and development breathes degree, accurate positioning, cost are low, contribute to easy to what is popularized under CT guiding The device of aspiration biopsy positioning, to fill up current technology blank.

Utility model content

The purpose of this utility model is to provide a kind of CT Guided Percutaneous Transthoracic Needle Aspiration Biopsies to breathe positioner, to solve Problem proposed in the above background technology.

To achieve the above object, the utility model provides following technical solution：

A kind of CT Guided Percutaneous Transthoracic Needle Aspiration Biopsies breathe positioner, including holder part and human identification part；Institute Stating holder part includes A-frame, fixed slip bar, laser lamp fixing bracket and laser lamp；The A-frame includes three branch Leg, one end of three supporting legs are fixedly mounted on clamping seat, and the other end of three supporting legs is mounted on plastic mattress；The clamping seat Top is provided with fixed slip bar, and screw thread is provided with fixed slip bar, is slided on fixed slip bar and is provided with laser lamp fixing bracket, swashed Laser lamp is installed on light lamp fixing bracket；Human identification part includes support plate, sucker and transparent panel, and the four of support plate Angle is mounted on sucker, and the midline position of support plate is vertically-mounted transparent panel, and scale is provided with transparent panel.

As further program of the utility model：Rotary switch is installed on the laser lamp fixing bracket.

As the utility model further scheme：The support plate is bending plate, and support plate lower part is provided with two Geometrical clamp.

Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in structure, manufacturing cost is low, It is easy to use, in use, only human identification part need to be put on patient body, support plate is horizontally fixed on human body by sucker It is under xiphoid-process, cradle portion is discrete beside patient, laser lamp is opened, it is support bracket fastened to adjust laser lamp through rotation turn switch Highly so that laser spots are incident upon on transparent panel, and laser spots are moved up and down with the patient respiratory depth, if held one's breath twice after air-breathing Laser spots are located at same position on transparent panel, and illustrating to hold one's breath twice, position is the same, and intrapulmonary lesion front and back position is constant, ensures into work Inspection pin is accurate to preset level, easy to operate, visual result；The utility model objective can judge patient it is front and rear breathe whether one Cause, so as to reduce scanning dose of radiation and repeatedly puncture the complication risk brought, greatly reduce operative failure risk, this Utility model thoroughly solves the problems, such as breathing influence, greatly improves puncture success rate, reduces complication rate, and due to cost Low, operation difficulty is small, quickly can popularize and apply, and has very big clinical value and economic results in society.
