Novel probe for probing sinus tract and fistula

Abstract

The invention discloses a novel probe for detecting sinus tract and fistula, which comprises a needle head and a needle body connected with the needle head. The needle head and the needle body are integrally formed by silica gel material; A through conduit is set, one end of the conduit is opened at the end of the needle body, and the other end is opened at the side of the needle or the connecting part of the needle body and the needle; a length scale line is arranged on the needle body, and the scale line cannot be detected by X-rays. It is made of penetrating materials; the novel probe of the present invention is soft in texture, good in curvature, easy to operate, convenient to directly obtain specific data of complex sinus tracts and fistula structures, and is widely used in the diagnosis and treatment of sinus tracts and fistula tracts.

Description

technical field [0001] The invention relates to the field of medical operation instruments, in particular to a novel probe for exploring sinus tracts and fistulas. Background technique [0002] Since probes are often used to detect sinuses and fistulas in surgical operations, most of the existing probes are solid metal needles. Improper use of metal needles can easily cause damage to sinus tracts and fistulas, resulting in new infections or false positives. Sometimes it is necessary to combine the contrast agent to further grasp the situation of the sinus and fistula, the existing probe does not have the function of draining the contrast agent into the sinus and fistula; in many cases, the structure of the sinus or fistula is complex and diverse, The trend is circuitous and even has different shapes and numbers of branches and secret passages. Using existing probes, it is not only inconvenient to operate but also impossible to completely explore the sinus or fistula channel ...

[0002] Since probes are often used to detect sinuses and fistulas in surgical operations, most of the existing probes are solid metal needles. Improper use of metal needles can easily cause damage to sinus tracts and fistulas, resulting in new infections or false positives. Sometimes it is necessary to combine the contrast agent to further grasp the situation of the sinus and fistula, the existing probe does not have the function of draining the contrast agent into the sinus and fistula; in many cases, the structure of the sinus or fistula is complex and diverse, The trend is circuitous and even has different shapes and numbers of branches and secret passages. Using existing probes, it is not only inconvenient to operate but also impossible to completely explore the sinus or fistula channel direction and other structural features; when the structure of the sinus and fistula to be explored When it is quite complicated, especially when there are branches and secret passages that need to be explored, if the specific data of the depth and width of each part of the sinus tract and fistula can be obtained intuitively, the diagnostic level of the probe to detect the sinus tract and fistula can be improved. Provide better data for treatment, thereby greatly improving the success rate of surgery; therefore, a new probe with soft texture, good curvature, easy operation, and easy to obtain specific data of complex sinus tracts and fistula structures is needed
