Description

Anoscope that facilitates use

Technical Field

The utility model relates to the technical field of devices capable of propping open anal sphincters in anorectal surgery, and particularly belongs to an anoscope convenient to use.

Background

Anoscopes are a conventional medical device commonly used in anorectal families for observation and treatment. The presence or absence of long polyps or hemorrhoids in the rectum can be visually observed through the anoscope, the position, size, shape and the like of the hemorrhoids can be clearly seen, and the anoscope is a basic tool and a method for diagnosing the hemorrhoids.

At present, the known anoscope structure consists of an anoscope tube and an anoscope core, wherein the anoscope tube is in a cylindrical structure with gradually reduced diameter, two ends of the anoscope tube are open, the anoscope core is cylindrical, a convex block is arranged at the head of the anoscope core, and the outer diameter of the anoscope core is slightly smaller than the inner diameter of the anoscope tube, so that the anoscope core can be just sleeved into the anoscope tube, and the convex block part at the front end of the anoscope core just extends out of the anoscope tube. In the anorectal surgery, when the operator uses, the anoscope sleeved with the endoscope core needs to be inserted into the anus, so that the endoscope tube can prop open the sphincter of the anal tube forming the anal tube, then the endoscope core is pulled out, the tissue condition in the deep part of the anal tube can be seen through the endoscope tube, and the operation is convenient.

The tissue condition of the anal canal can be seen from the mouth of the anal speculum, in order to more accurately reflect the condition in the anal canal of the patient, the part of the patient to be observed needs to be kept in a relaxed state, meanwhile, the anal canal sphincter of other parts needs to be propped up to be convenient for the operator to watch, therefore, the tissue part of each pathological change in the anal canal can be observed only by repeatedly inserting and withdrawing the lens cone in the process of using the anal speculum, a fixed positioning structure does not exist between the currently known anal canal and the lens core, the lens core needs to be pressed forcibly by a doctor in use, the lens core and the lens canal become an integral part to be used, the repeated inserting and withdrawing of the anal speculum can make the doctor inconvenient to use, and the pain of the patient is easily increased.

SUMMERY OF THE UTILITY MODEL

In order to achieve the purpose, the anoscope convenient to use provided by the utility model comprises an anoscope tube and an anoscope core inserted in the anoscope tube, wherein the anoscope core comprises an anoscope core head and a handle fixedly connected with the anoscope core head, the open end of the anoscope tube extends outwards to form a truncated cone-shaped anoscope edge, an anoscope core positioning structure is arranged between the anoscope edge and the handle, and the anoscope core positioning structure comprises a guide groove arranged on the inner side of the anoscope edge and a positioning part arranged on the handle.

Preferably, the guide way is for setting up at the mirror along the bar recess of inboard circumference, the setting element is circular, the external diameter of setting element is the same along the internal diameter with the mirror of guide way department, the outside of setting element still is provided with the reference column, be provided with the boss in the guide way, when the mirror core is pegged graft in the mirror tube, the reference column on the setting element is in the guide way in order to inject the mirror core and only can rotate at the length range of guide way.

Preferably, the width of the guide groove is equal to the outer diameter of the positioning column.

Preferably, the mirror is further provided with an open slot along the inner side circumferential direction, the inner diameter of the mirror edge at the position of the open slot is larger than that of the mirror edge at the position of the guide slot, and the open slot is connected with the end part of the guide slot.

The utility model has the advantages that: is beneficial to the operation, is convenient for doctors to use and reduces the pain of patients. Through being provided with mirror core location structure, when using, reference column on the mirror core gets into the guide way, anticlockwise rotation mirror core, and reference column on the mirror core can only rotate at the length within range of guide way under the injecing of guide way, and the doctor need not press the mirror core with strength again.

Through being provided with the boss, rotatory mirror core in-process, the reference column on the mirror core appears hindering in the boss position, and hand can feel hard and slide the sound that the boss collided the guide way bottom surface at this moment, reminds the doctor to block in place mirror core and mirror tube, can use. The lens core and the lens tube are assembled into a whole under the action of the positioning column and the guide groove, and meanwhile, the lens core and the lens tube are assembled in place, so that the lens tube is convenient to use, and the pain of a patient is reduced.

Through being provided with the open slot on the mirror tube, can get into the mirror tube with the installation of the mirror core that contains the reference column, make the reference column get into the guide way.
