Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical instruments, in particular to a rotary invaginated anoscope. Background Art
[0002] Anoscope is a tool used for anorectal disease examination. Currently, anoscopes on the market are generally composed of a tube and a core. The tube is conical in shape, with both ends open, and the core is an arc-shaped protrusion. A push rod is provided on the core. When in use, the core is inserted into the tube and extended out of the tube through the push rod, and then the core is placed against the patient's anus to stretch the anus open. Then the tube and the core are slowly inserted into the anus. After they are in place, the core is pulled out, and the tissues in the anus can be observed through the tube. However, this traditional anoscope can only be observed through the open end, with a small visual range, and requires repeated plugging and unplugging to complete the observation. Not only is the operation complicated, but it is also easy to cause discomfort to the patient.
[0003] In view of the above problems, an anoscope with a publication number of CN209404734U is disclosed on the market. The anoscope consists of an outer sleeve and an inner sleeve. A plurality of side windows are arranged on the side wall of the outer sleeve, and a semicircular groove and a cone are arranged on the inner sleeve. The inner sleeve is inserted into the outer sleeve and the cone on the inner sleeve extends out of the outer sleeve. When in use, the inner sleeve and the outer sleeve are inserted into the anus together. By rotating the outer sleeve, abnormal tissue can be squeezed into the side window, and then the inner sleeve is rotated to align the semicircular groove on the inner sleeve with the side window with the abnormal tissue, so that the abnormal tissue is exposed in the inner sleeve for easy disposal. However, an anoscope with this structure has the following defects when in use: since there are a large number of side windows on the outer sleeve and there is a semicircular groove on the inner sleeve, the inner sleeve cannot completely block the side windows on the outer sleeve. During the process of inserting the anus into the anus, body fluids in the anus can easily enter the anoscope, blurring the anoscope's field of view and affecting the doctor's operation; the anoscope is suitable for areas where internal hemorrhoids occur, and cannot effectively examine diseased tissues in other locations in the anus.

[0024] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.
[0025] like Figures 1 to 8 As shown, the rotary invaginated anoscope described in the utility model comprises: a conical exoscope 1 and an endoscope 2, both of which are made of plastic material, and the tapers of the exoscope 1 and the endoscope 2 are the same. An external observation port 11 is provided on the front side wall of the exoscope 1, and the external observation port 11 is in the shape of a semicircular groove, and a rounded corner is provided on the edge of the external observation port 11. The height of the external observation port 11 accounts for 41% to 45% of the height of the exoscope 1, thereby improving the observation area of the exoscope 1, and an arc-shaped top 12 is provided at the bottom of the exoscope 1, and an annular groove 13 with an S-shaped cross-section is provided on the inner side wall between the external observation port 11 and the arc-shaped top 12, and a left handle 14 is provided on the exoscope 1, and the left handle 14 is located on the left side of the external observation port 11, and a rough surface is provided on the left handle 14, which can prevent slipping and is convenient to hold.
[0026] A trumpet-shaped retaining ring 21 is extended from the top of the endoscope 2, and the small-diameter end of the trumpet-shaped retaining ring 21 is connected to the top of the endoscope 2. An internal observation port 22 is opened on the front side wall of the endoscope 2. The internal observation port 22 is also in the shape of a semicircular groove, and rounded corners are also provided on the edge of the internal observation port 22. The height of the internal observation port 22 is not less than the height of the external observation port 11. An arc-shaped cover 23 is provided at the bottom of the endoscope 2. The arc-shaped cover 23 can improve the supporting strength of the endoscope 2. An annular block 24 with an S-shaped cross-section is provided on the outer side wall of the endoscope 2 between the internal observation port 22 and the arc-shaped cover 23. A right handle 25 is provided on the large-diameter end of the trumpet-shaped retaining ring 21. The right handle 25 is located on the right side of the internal observation port, and a rough surface is also provided on the right handle 25.
[0027] The endoscope 2 is inserted into the exoscope 1, and the annular block 24 on the endoscope 2 is inserted into the annular groove 13 on the exoscope 1. The trumpet-shaped retaining ring 21 on the endoscope 2 is located on the outside of the exoscope 1, leaving a gap of 0.1±0.05mm between the endoscope 2 and the exoscope 1, and the outer wall of the annular block 24 is against the inner wall of the annular groove 13. In this way, the gap between the endoscope 2 and the exoscope 1 will neither interfere with the rotation therebetween nor prevent the anal tissue from being pinched. The endoscope 2 can stably rotate coaxially in the exoscope 1 without shaking. Since the cross-sections of the annular block 24 and the annular groove 13 are both S-shaped, it is convenient for the annular block 24 to be inserted into the annular groove 13, and it can prevent the annular block 24 from being easily separated from the annular groove 13. When the endoscope 2 is inserted into the exoscope 1, the external observation port 11 and the internal observation port 22 are aligned along the radial circumference.
[0028] When in use, the endoscope 2 is inserted into the exoscope 1, and then the left handle 14 and the right handle 25 are rotated until they are aligned up and down. At this time, the internal observation port 22 is offset from the external observation port 11, that is, the external observation port 11 is located at the front side, and the internal observation port 22 is located at the back side, so that a closed state is formed between the endoscope 2 and the exoscope 1. Then, the left handle 14 and the right handle 25 are held at the same time to press the arc-shaped top 12 on the exoscope 1 against the anus, and then the exoscope 1 is squeezed into the anus with force. The endoscope 1 is conical in shape, which will slowly stretch the anus during the insertion process to reduce the patient's discomfort. The edges of the external observation port 11 are all rounded, and the anal tissue will not feel uncomfortable when it contacts the external observation port 11. The trumpet-shaped baffle ring 21 on the endoscope 2 can prevent the body fluid in the anus from splashing out. The closed endoscope 2 and the external scope 1 can prevent the body fluid from entering the interior. After the external scope 1 is in place, the external scope 1 and the external scope 1 can be rotated by the left handle 14 and the right handle 25 respectively. Endoscope 2, first place the left handle 14 and the right handle 25 on the left and right sides, at this time, the external observation port 11 and the internal observation port 22 overlap to form a complete observation area, and the anal tissue corresponding to the observation area is exposed in the observation area, so the anal tissue can be observed. If there is no abnormality in the anal tissue in the observation area, rotate the external observation port 11 and the internal observation port 22 180°, so that the external observation port 11 and the internal observation port 22 overlap in the opposite direction to form a new complete observation area, and the remaining anal tissue will be exposed in the observation area. During the rotation process, it is necessary to rotate the exoscope 1 first and then rotate the endoscope 2 along the rotation direction of the exoscope 1, or rotate the endoscope 2 first and then rotate the exoscope 1 along the rotation direction of the endoscope 2. The exoscope 1 and the endoscope 2 cannot be rotated at the same time, because simultaneous rotation requires simultaneous action of both hands, and the two hands are prone to generate pulling force on the anoscope when performing simultaneous rotation actions, which will cause serious discomfort to the patient or even hurt the patient. When diseased tissue is found in the observation area, the exoscope 1 and the endoscope 2 are rotated in opposite directions to reduce the area of the observation area formed by the overlap of the external observation port 11 and the internal observation port 22, reduce the exposure of normal anal tissue, and try to expose only the diseased tissue in the observation area to facilitate treatment. When rotating in opposite directions, the exoscope 1 and the endoscope 2 are rotated respectively, and cannot be rotated at the same time.
[0029] When the anoscope is inserted into the anus for observation, the market either uses a second person to hold a light source for illumination, or sets a light source in the anoscope for illumination. The light source in the anoscope is generally set on the inner wall with a circle of light strips, and then the light strips are powered on for illumination. However, this method not only has the risk of leakage, but also needs to dispose of the light strips together with the anoscope after use, resulting in waste. In this embodiment, white light-storage films 3 are pasted on the inner side walls at the upper and lower ends of the inner observation port 22. The white light-storage films 3 can generate light for a long time in a dark environment after absorbing light energy. No power supply is required. It is only necessary to ensure that the white light-storage films 3 are always under light conditions during storage. The upper and lower white light-storage films 3 can provide sufficient brightness to meet the observation requirements. Before leaving the factory, the manufacturer can paste the white light-storage films 3 on the inner side wall of the endoscope 2, and then disinfect and ship it, or the hospital can purchase the anoscope and the white light-storage films 3 separately and paste them by themselves before use. The white light-storage films 3 sold separately also need to be disinfected and sealed for storage.
[0030] When the anoscope is inserted into the anus, it is necessary to hold the left handle 14 and the right handle 25 at the same time to operate. When holding the left handle 14 and the right handle 25, the two handles are easily offset and destroy the sealing state between the endoscope 2 and the exoscope 1, which will cause body fluids to flow into the anoscope and contaminate the anoscope and the white light-storing film 3. In this embodiment, a connecting hole is provided on the left handle 14, a lower positioning block 15 is clamped upward in the connecting hole of the left handle 14, a positioning protrusion 151 is provided on the top wall of the lower positioning block 15, a water outlet 152 is provided between the positioning protrusion 151 and the lower positioning block 15, a connecting hole is also provided on the right handle 25, an upper positioning block 26 is clamped downward in the connecting hole of the right handle 25, a positioning groove 261 is provided on the bottom wall of the upper positioning block 26, when the left handle 14 and the right handle 25 are aligned up and down, the positioning protrusion 151 is clamped into the positioning groove 261, and then a hot air blower is used to perform hot air welding on the clamped positioning protrusion 151 and the positioning groove 261, so that the positioning protrusion 151 and the positioning groove 261 are welded together. When in use, the doctor directly holds the two connected left handles 14 and right handles 25 to operate, and the exoscope 1 and the endoscope 2 will not be offset. When the anoscope is squeezed into place, the left handle 14 and the right handle 25 are gently moved to both sides, and the water outlet 152 between the positioning protrusion 151 and the lower positioning block 15 will be broken, and the upper positioning block 26 and the lower positioning block 15 will be separated. The exoscope 1 and the endoscope 2 can be freely rotated by the left handle 14 and the right handle 25, and the upper positioning block 26 and the lower positioning block 15 can automatically fall off from their corresponding connecting holes after separation.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modification or equivalent replacement that does not depart from the spirit and scope of the utility model should be included in the scope of protection of the claims of the utility model.
