Abstract

A CT puncture locating frame, the utility model belongs to the medical apparatus technical field, in particular to a CT puncture locating frame. The purpose of the utility model is to provide a CT guidance percutaneous puncture stereotactic locating frame, the CT puncture locating frame with which the medical personnel more accurately locate and destroy the lesion cell in the percutaneous puncture, but is not destroyed the normal tissue of the lesion circumference. The technical proposal of the utility model is that a locating frame comprises a frame seat, a transversely arranged U-shaped fixed arm, an oriented rod, and a fixed plate. The frame seat is semicircular, a concentric arc-shaped concave groove is in the frame seat, the oriented rod is arranged on a arc-shaped guide groove, a fixed plate is connected on the frame seat, the transversely arranged U-shaped fixed arm is arranged at two ends of the frame seat, a scale surrounding the centre of a circle and used for measuring the angle is arranged on the frame seat. The utility model is used in the CT puncture localization.

Description

The CT locating rack that punctures

Technical field: this utility model belongs to technical field of medical instruments, is a kind of CT puncture locating rack specifically.

Background technology: at present a lot of diseases can be passed through CT orientation direction percutaneous puncture without surgical incision, obtain diagnosis and treatment, particularly tumor disease with Minimally Invasive Surgery, histological typing is very important, often need before treatment, to obtain clear and definite pathological diagnosis, and formulate 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, puncture error localised puncture repeatedly often occurs, cause the 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, it can overcome the deficiencies in the prior art, more accurate location and the accurate CT puncture locating rack that destroys the focus cell and don't damage perilesional normal structure when making medical worker's percutaneous puncture.

The technical solution of the utility model is: locating rack is by stand, horizontal U-shaped fixed arm, orientation lever, and fixing head is formed.Stand is semicircle, in the middle of a concentric arc groove is arranged, orientation lever is contained on the arc guide groove, is connected with a fixing head on the stand, horizontal U-shaped fixed arm is contained in two ends of stand, has on the stand around the scale center of circle, that be used to measure angle.

The novel beneficial effect of this practicality is: 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.

Description of drawings: accompanying drawing 1 is this utility model structural representation.

1 is mounting among the figure, and 2 is horizontal U-shaped fixed arm, and 3 is orientation lever, and 4 is fixing head.

The specific embodiment: locating rack is by stand 1, horizontal U-shaped fixed arm 2, orientation lever 3, and fixing head 4 is formed.Stand 1 is semicircle, in the middle of a concentric arc groove is arranged, orientation lever 3 is contained on the arc guide groove, is connected with a fixing head 4 on the stand 1, horizontal U-shaped fixed arm 2 is contained in two ends of stand 1, has on the stand 1 around the scale center of circle, that be used to measure angle.During use stand is placed upper body part, be fixed on the both sides of bed board with horizontal U-shaped fixed arm, be pressed on the patient body with fixing head, aim at point of puncture with orientation lever, puncture needle is close to orientation lever and is punctured.
