Novel probe for probing sinus tract and fistula

Abstract

The invention discloses a new type probe used to explore sinus tracts and fistulas, comprising a pinhead and a needle shank connected with the pinhead; wherein, the pinhead and the needle shank are one-piece type adopting silica gel; a transfixing pipe is arranged in the pinhead and the needle shank along the axis, the opening of one end of the pipe is arranged at the end of the needle shank, the opening of the other end of the pipe is arranged at the pinhead or at the lateral face of the connecting part of the needle shank and the pinhead; the needle shank is provided with a length scale mark made of the materials which can not be penetrated by X ray. The invention has the advantages of soft texture, favorable curvature, convenient operation, convenient and direct acquisition of complex structures of sinus tracts and fistulas and extensive application in diagnosis and treat of sinus tracts and fistulas.

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
