Technical Field
The invention relates to the technical field of medical instruments, in particular to a disposable visible anoscope
Background
Anoscopes are often used as a traditional medical device for the observation and treatment of anorectal diseases. The anorectal diseases are various in types, similar in symptoms and easy to misdiagnose, and the anoscope can visually observe lesions at the tail end of the anal canal and rectum and near the dentate line and can further carry out biopsy and related treatment, so that the anorectal diseases such as proctitis, rectal polyps, rectal cancer, mixed hemorrhoids, anal papilloma and anal fissure can be examined, and the anorectal diseases have an irreplaceable effect.
The conventional common method for anoscopes comprises the following steps: firstly, performing digital rectal examination, then holding the anoscope with the right hand and supporting the core with the thumb, firstly coating the tip of the anoscope with a lubricant, pulling the right hip open with the left thumb and the index finger to display the anus opening, and massaging the anal margin with the head of the anoscope to relax the sphincter; slowly inserting towards the umbilicus, and making the umbilicus into the ampulla of rectum from the direction changed to sacrum after passing through the anal canal; taking out the inner core of the anoscope, paying attention to the properties of blood stain and blood stain on the core, wiping off the core by using a cotton ball on forceps if secretion exists in the rectum, and then inspecting in detail; looking up the color of the mucosa, paying attention to whether ulcers, polyps, tumors and foreign bodies exist, then slowly drawing out the anoscope, and paying attention to internal hemorrhoids, anal papilla, anal crypt or anal fistula internal orifice and the like at the dental line. When a doctor uses the traditional anoscope for examination, the doctor usually needs to closely observe, the internal mucosa cannot be seen clearly, the possibility of misdiagnosis is high, and the operation is inconvenient under the condition of sampling.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides the disposable visual anoscope which is convenient to operate and can observe the internal condition of the anus in real time.
In order to achieve the purpose, the invention adopts the following technical scheme:

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1 to 5, the embodiment of the invention provides a disposable visual anoscope, which comprises an anoscope body 1 and an inner core movably connected with the anoscope body 1, wherein the anoscope body 1 comprises a handle 1-1 and a sheath tube 1-2 connected with the handle 1-1, the sheath tube 1-2 is internally provided with an operation channel 3 which extends forwards and backwards, the operation channel 3 is provided with an inlet 4 and an outlet 5 through which the inner core can pass, a camera shooting cavity 6 which can contain a camera shooting component is defined in the operation channel 3, the camera shooting cavity 6 extends from a proximal end to a distal end and forms an insertion opening 4 at the distal end, the radial dimension of at least part of the distal end of the inner core is configured to be positioned and matched with the anoscope body 1, the inner diameter of the operation channel 3 of the technical scheme is configured to contain the camera shooting cavity 6 and the inner core, the arrangement of the camera cavity 6 does not influence the insertion and extraction of the inner core in the operation channel 3, so that the process of placing an anoscope into a patient can be observed in real time, the dislocation is prevented, and the situation that the camera cavity 6 is arranged on the inner core and the sampling result cannot be monitored after the inner core is pulled out is avoided; in particular, the camera cavity 6 can be mounted on the inner wall of the anoscope body 1, the insertion opening 4 can penetrate through the side (in this way, not shown in the figures), or the camera cavity 6 can penetrate through the insertion opening 4 from the inlet 4.
Specifically, as shown in fig. 2, the inner core has an operation portion 7 for the medical staff to operate and a protruding portion 8 extending forward from the operation portion 7, the operation passage 3 has a positioning wall 10, an outer wall of the protruding portion 8 extends at least partially radially toward the positioning wall 10 to form a positioning portion 9 in positioning fit with the positioning wall 10, the positioning portion 9 cooperates with the positioning wall 10 to limit the operation portion 7 outside the entrance 4, and the inner core is prevented from slipping in the direction of the patient's body, which causes inconvenience in operation;
more specifically, the positioning wall 10 may be a circumferential wall formed at the position near the inlet 4 of the operation channel 3, and the fitting manner of the positioning portion 9 and the circumferential wall is snap fit at this time, or a top wall formed radially outward from the inlet 4, and the fitting manner of the top wall and the positioning portion 9 is stop fit at this time;
further, as shown in fig. 3, the front end of the camera shooting cavity is bent inwards to form an inclined part 11, and the front end of the camera shooting cavity is made of soft materials so as to realize multi-directional rotation and enlarge the observation range and space of the camera shooting assembly.
In some embodiments, the insertion opening 4 is configured to be disposed through the inlet 4 or defined at the inlet 4, i.e., the imaging chamber 6 shares one operation channel 3 inlet 4 with the core;
furthermore, the front end of the internal core of the existing clinical anoscope is generally hemispherical, if the image pickup cavity 6 penetrates out of the inlet 4, the internal core cannot be matched with the anoscope body 1 for use, and based on the situation, the image pickup cavity 6 is arranged in the middle of the internal core, but the design has the defects that when the anoscope is placed in place, a doctor can take out the internal core for next operation, and after the internal core is taken out, the internal operation condition cannot be continuously observed; therefore, the camera shooting cavity 6 is optimally arranged in the operation channel 3, so that the observation and monitoring of the condition in the anus in the whole operation or inspection process can be realized, and on the basis, in the scheme, as shown in fig. 5, the positioning part 9 forms a notch for the insertion hole 4 to penetrate out, the structure of the far end of the inner core is changed, the influence of the realization of the visual function on the operation of the inner core is avoided, and meanwhile, the positioning part 9 of the inner core can prevent the inner core from slipping to the near end;
more preferably, as shown in fig. 1, 2 and 5, the positioning portion 9 is at least two side wings symmetrically formed on the outer wall of the protruding portion 8, and the notch is formed between the two side wings.
The invention further provides a visual anoscope system, which comprises the visual anoscope and a camera system connected with the anoscope.
Firstly, when the anoscope operation examination process is realized, the embedded position can be monitored in real time and the internal environment can be observed, namely, the camera shooting cavity 6 is arranged in the operation channel 3 and is led out from the inside of the body or is led out from the inlet 4; then the matching problem of the camera shooting cavity 6 and the inner core and the slipping problem of the inner core caused by leading the camera shooting cavity 6 out of the inlet 4 are solved, the positioning part 9 of the inner core can prevent the inner core from slipping by changing the structure of the far end of the inner core, and meanwhile, the other function of the positioning part 9 is to form a notch for leading the camera shooting cavity 6 out, so that the defect that the operation of the camera shooting cavity 6 and the inner core can be influenced mutually is avoided; and finally, the front end of the camera shooting cavity 6 is inclined inwards to ensure the observation of the camera shooting assembly in the largest range, and the camera shooting assembly is convenient to put in.
It should be noted that the above embodiments are merely representative examples of the present invention. Many variations of the invention are possible. Any simple modification, equivalent change and modification of the above embodiments according to the spirit of the present invention should be considered to be within the protection scope of the present invention.
