Description

CT guide light beam positioning biopsy puncture device

Technical Field

The utility model relates to a medical equipment field, particularly, the utility model relates to a CT guides light beam location biopsy puncture device.

Background

The lesion qualitative diagnosis of the nodular lesion nuclei of the lung in the peripheral area of the lung and near the pleura or the chest wall is difficult, and the lump can be clinically and qualitatively diagnosed, a treatment scheme can be formulated and the prognosis can be realized by using the percutaneous lung aspiration biopsy under the guidance of CT; before puncture, all patients are subjected to conventional enhanced CT scanning, preoperative detection, blood coagulation time, platelet count and the like; strictly screening the indications and the contraindications and making a puncture decision; the preoperative and intraoperative positioning of the puncture biopsy under the guidance of CT is the key of successful operation, generally a method for training breath holding and body surface hurdle positioning of a patient is adopted, a small part of provincial trimethyl hospitals in China adopt laser positioning of an extraterrestrial introduced auxiliary system, the equipment is expensive and difficult to popularize, operation is carried out after two times of scanning in the operation is adopted to evaluate whether breathing is consistent, needle insertion is carried out in two steps, the needle insertion accuracy and the biopsy success rate are increased, whether two times of breathing are consistent or not is mentioned in technical operation, but in actual work, whether the breathing is consistent or not is often difficult to judge by naked eyes, the self feeling of the patient is also difficult to control, particularly, in a stress state, the displacement of focus in lung is caused by poor breathing control in clinical work, repositioning, repeated scanning and secondary puncture are needed, and pneumothorax complications are greatly increased, leading to a risk of surgical failure; in clinical work, the most direct reason for puncture failure is that patients have poor breathing fit, when the focus is smaller than 3cm, the focus is easily influenced by breathing, and particularly, the two lower lung focuses are influenced most by breathing because the diaphragm participates in breathing and the vertical displacement range is large. The lung puncture device of the CT guide beam positioning biopsy puncture device is designed to be more traditional, cannot be fixed in position, often deviates when puncturing the lung of a patient, and causes misoperation.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the main technical problem who solves provides a CT guides light beam location biopsy piercing depth, can fix on the operating table of CT machine, fixes the position and plays the guide effect for lung piercing depth, prevents to often can take place the skew to disease lung puncture, flexible operation, convenient to use.

In order to achieve the above object, the present invention provides the following technical solutions:

this CT guide light beam location biopsy puncture device includes the platelike mounting panel of U-shaped, be equipped with the same U-shaped track pole of two sizes perpendicularly on the mounting panel, two track poles are parallel to each other, all overlap on two track poles and have the horizontal slide tube of pipe shape, be connected with the pole of taking of pipe shape perpendicularly between two horizontal slide tubes, it has the vertical slide tube of pipe shape to overlap on the pole of taking, the outer wall of vertical slide tube is equipped with pipy stand pipe perpendicularly, install the lung puncture device that can freely stretch out and draw back in the stand pipe.

As the further optimization of the technical scheme, the support plate and the track rod are both made of aluminum alloy and are connected through welding.

As a further optimization of the technical scheme, the transverse sliding pipe and the lapping rod are both made of aluminum alloy and are connected through welding.

As a further optimization of the technical scheme, the longitudinal sliding pipe and the guide pipe are both made of aluminum alloy and are connected through welding.

As a further optimization of the technical scheme, the length of the lung puncture device is larger than that of the guide tube.

The beneficial effect of adopting above technical scheme is: when the CT guide beam positioning biopsy puncture device is used, the support plate is placed on an operating table of a CT machine, and a patient lies in a concave hole in the middle of the support plate. Then two transverse sliding tubes are moved on the track rod, the longitudinal sliding tube is slid on the lapping rod, the position of the guide tube is adjusted to face the lung of the patient, and finally the lung puncture device is used for puncturing the lung of the patient along the guide tube to complete biopsy puncture. The CT guiding beam positioning biopsy puncture device can be fixed on an operating table of a CT machine, and the fixed position plays a guiding role for the lung puncture device, so that the offset of the patient lung puncture device often caused by the fixed position is prevented, and the CT guiding beam positioning biopsy puncture device is flexible to operate and convenient to use.
