Abstract

The utility model relates to a CT stereo location bracket for guiding percutaneous to puncture, which is applicable to guide percutaneous to puncture or cure diseases through CT locating. The utility model mainly comprises a stand, an orientation lever, and a dead lever, which can lead a puncture patient to accurately puncturatio focus, and can effectively extinct focus tissue, and can reduce unnecessary damage and complication. Compared with the prior art, the utility model has the advantages that targets location is more accurate, operating process is more convenient and rapid, which can reduce repeated puncture and complication which is caused by repeated puncture.

Description

A kind of CT guiding percutaneous puncture stereotaxic frame

Technical field:

This utility model relates to a kind of CT guiding percutaneous puncture stereotaxic frame, mainly is adapted to pass through the CT location, guides percutaneous puncture to carry out using in biopsy or the treatment disease.

Background technology:

Along with the continuous development of Medical Technology, at present a lot of diseases can be passed through CT orientation direction percutaneous puncture without surgical incision, obtain diagnosis and treatment with Minimally Invasive Surgery.Tumor disease particularly, histological typing is very important, often needs obtain clear and definite pathological diagnosis before treatment, and formulates therapeutic scheme.Therefore, for endoceliac tumor, need under CT location, guiding percutaneous transthoracic needle biopsy or insert argon helium superconduction targeting surgery systems, promptly argon helium knife is thoroughly treated tumor.Tumor or get biopsy in the percutaneous puncture in treating body cavity in the past, puncture person can only rely on CT scan to determine the degree of depth and the angle of point of puncture, subjectivity is determined into the pin angle, accuracy is relatively poor, and the influence of Body Position Change when in piercing process, being subjected to patient's body movement, the puncture error often appears, need localised puncture repeatedly, cause tumor by local plantation to shift, and severe complications such as pneumothorax, hemothorax, internal organs be hemorrhage occur.

Summary of the invention:

The purpose of this utility model provides a kind of CT guiding percutaneous puncture stereotaxic frame, and it can overcome the deficiencies in the prior art, and more accurate location is destroyed the focus cell and don't damaged perilesional normal structure with accurate when making medical worker's percutaneous puncture.

This utility model is achieved in that it mainly is made up of stand, orientation lever, fixed bar, wherein, stand is a semi-round ring shape, in the middle of a concentric arc guide barrel is arranged, orientation lever is contained on the arc guide barrel, fixed bar is contained in two ends of stand, has on the stand around the scale center of circle, that be used to measure angle.

This utility model can make puncture person's focus target spot that can puncture exactly, more effectively eliminate lesion tissue, reduce unnecessary damage and complication, compared with prior art, has more accurate, the operating process more convenient and quicker in target spot location, the advantages such as complication that can reduce repeated localised puncture and introduce therefrom.

Below in conjunction with accompanying drawing this utility model is further described.

Description of drawings:

Fig. 1 is a structural representation of the present utility model

The specific embodiment:

As shown in Figure 1, this utility model mainly is made up of stand 1, orientation lever 2, fixed bar 3,4, wherein, stand 1 is a semi-round ring shape, in the middle of a concentric arc guide barrel 5 is arranged, orientation lever 2 is contained on the arc guide barrel 5, and is fixing or loosen by securing member 6, fixed bar 3,4 is contained in two ends of stand 1, and is fixing or loosen by securing member 7,8 respectively.

During use, for breast, space occupying lesion or tumor are arranged and patient that the skin puncture of need passing through is got biopsy or interior therapeutic in the body cavitys such as abdominal part, carry out CT scan earlier, determine the three-dimensional position of focus, and selected skin-piercing point, mark, and on the dynamo-electric brain of CT fluorescent screen, accurately calculate the focus target spot to the distance of skin penetrating point and with respect to the puncture angle on the horizontal line, again two ends of the present utility model are passed through fixed bar 3,4 are fixed on the center line level of clinostatism patient health both sides, mobile then orientation lever 2, make it aim at the skin penetrating point, and it is shown to be in stand 1, on the pairing scale of the puncture angle position, then fixing orientation lever 2 by securing member 6, needle tip is aimed at the skin penetrating point, the puncture backshank is close to orientation lever 2, and punctures into pin according to the depth of needle of CT measurement, and needle point just accurately arrives the focus target spot that needs puncture.
