Abstract
The utility model discloses a novel anus intestines probe, needle bar including the cylindric hollow structure of flexible, set up the metal wire with the isometric helical structure of needle bar in the pipe wall of needle bar, both ends set up spherical structure's syringe needle about the needle bar, the bell mouth has all been seted up in the syringe needle, the bell mouth communicates with each other with the hollow structure in the needle bar. The utility model has simple structure, low cost and wide popularization, and the metal wire with the helical structure arranged in the needle rod is not easy to be broken or bent to cause the blockage of the probe, so that the risk of traumatic operation or false passage is avoided; meanwhile, the fistula shape and the internal orifice position can be accurately judged by a dyeing radiography method through the hollow structure of the needle rod, and the flushing function is realized.
Description
Technical Field
The utility model relates to the technical field of medical equipment, concretely relates to novel anus intestines probe.
Background
anal fistula and perianal abscess (hereinafter referred to as perianal abscess) are common clinical diseases. With the intensive research on diseases and the increasing health requirements, other areas of the body have pathological fistulous tracts and sinus tracts such as: diseases such as pre-auricular fistula, latent sinus of hair on tail, hidradenitis suppurativa and the like are not rare clinically. The common characteristics of the diseases are the existence of pathological fistula tracts and sinus tracts in different levels, depths and degrees in the body, and the key to completely treat the diseases is to clearly explore and completely treat the fistula tracts and sinus tracts, and of course, anal fistula and perianal abscess also need to treat the internal anal orifice connected with the fistula tracts.
Anal fistula surgery requires, from a clinical point of view, the finding of a reliable fistula and internal orifice location, and tissue site encroachment by the fistula, whether from a diagnostic, therapeutic, or prognostic standpoint. If the position of the internal orifice and the fistula tract are not clearly checked during the operation, fistula residue, internal orifice residue or new infection focus is easily formed, the operation fails and the disease condition recurs. It follows that the success and failure of an anal fistula procedure is critical to correctly finding and manipulating the internal orifice and fistula anatomical site. High-order complexity anal fistula is higher because of the position of its pathological change, and the many complicacies of pipeline are crooked, often has deep dead space and branch pipe, consequently the treatment degree of difficulty is big, is one of the difficult disease of surgery.
Most of the probes clinically used at present are silver ball probes and the top ends of the probes are spherical so as to be beneficial to exploring anal fistula and internal orifice, so that the following problems exist: 1) the silver is soft, so that although the silver has certain flexibility, the silver is easy to break or cause probe blockage after being bent; 2) most of the existing silver ball probes are solid structures, the fistula shape and the internal orifice position cannot be accurately judged by combining a staining radiography method, and the existing silver ball probes do not have the flushing function.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a novel anus intestines probe to prior art's defect and not enough.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a novel anus intestines probe, includes the needle bar of flexible cylindric hollow structure, its innovation point lies in: the needle comprises a needle rod and is characterized in that a metal wire of a spiral structure with the same length as the needle rod is arranged in the tube wall of the needle rod, needle heads of a spherical structure are arranged at the left end and the right end of the needle rod, tapered holes are formed in the needle heads, and the tapered holes are communicated with a hollow structure in the needle rod.
Furthermore, the needle head and the needle rod are integrally formed and made of medical high polymer materials.
Further, the inner diameter of the hollow structure of the needle rod is larger than the outer diameter of the syringe needle.
after the structure is adopted, the utility model discloses beneficial effect does:
The utility model has simple structure, low cost and wide popularization, and the metal wire with the helical structure arranged in the needle rod is not easy to be broken or bent to cause the blockage of the probe, so that the risk of traumatic operation or false passage is avoided; meanwhile, the fistula shape and the internal orifice position can be accurately judged by a dyeing radiography method through the hollow structure of the needle rod, and the flushing function is realized.

Description of reference numerals:
1 needle rod, 2 metal wires, 3 pinheads, 4 conical holes and 5 hollow structures.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
in order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the following detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.
Referring to fig. 1-2, a novel anorectal probe comprises a bendable cylindrical needle rod 1 with a hollow structure 5, a metal wire 2 with a spiral structure and equal to the needle rod is arranged in the wall of the needle rod 1, needle heads 3 with spherical structures are arranged at the left end and the right end of the needle rod 1, tapered holes 4 are formed in the needle heads 3, and the tapered holes 3 are communicated with the hollow structure 5 in the needle rod 1. Because the metal wire 2 with the spiral structure has good toughness, the probe is not easy to break or bend when in use, and the probe is blocked, so that the risk of traumatic operation or false passage is avoided.
In this embodiment, the needle head 3 and the needle bar 1 are integrally formed, and are made of medical polymer material. The needle head 3 and the needle rod 1 are integrally formed to ensure the use stability, and medical high polymer materials can ensure no harm to human bodies and ensure the use safety, meanwhile, the surface of the probe can be coated with a Tin coating, and the Tin coating has the advantages of high hardness, good toughness, high bonding strength, small friction coefficient, stable chemical performance, no toxicity, light weight, excellent biocompatibility and the like, is an ideal medical material, improves the use efficiency and relieves the pain of patients.
In this embodiment, the inner diameter of the hollow structure 4 of the needle rod is larger than the outer diameter of the syringe needle, so that the syringe needle can be inserted conveniently.
The above description is only for the purpose of illustrating the technical solutions of the present invention and not for the purpose of limiting the same, and other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
