And those skilled in the art should understand that "far" and "near" do not refer to the three-dimensional space straight-line distance from the user.

[0033] With the development of medical technology, endoscopy has become a routine examination and treatment method for the digestive system. Among them, colonoscopy is a diagnostic method used by doctors to examine lesions inside the large intestine and colon. A colonoscope is a slender and flexible medical instrument with a diameter of about 1 cm, which is often equipped with a camera system. During the diagnosis and treatment process, the distal end of the colonoscope enters the rectum through the anus until the ileum, allowing the doctor to observe the internal conditions of the colon and rectum.

[0034] Specifically, during the colonoscopy, the patient must lie on his left side with his knees bent and extended. The doctor slowly inserts the colonoscope through the anus and observes the intestinal cavity for lesions. The entire examination process takes about 10 to 20 minutes. If colonoscopy treatment is required, it may take 1 to 2 hours of treatment time.

[0035] During this process, the doctor often needs to control the operating unit with one hand and the endoscope with the other hand to prevent the endoscope from shifting due to lack of fixation, which causes inconvenience in operation. In addition, during puncture treatment under ultrasound endoscopy and endoscopic pancreaticobiliary duct lithotomy, an assistant is required to assist in fixing the endoscope, which is prone to poor fixation after a long time.

[0036] In order to solve the above-mentioned problem, the present application designs an endoscopic examination auxiliary fixing device to fix the endoscope body during the endoscopic examination process to prevent the endoscope body from shifting and affecting the colonoscopy diagnosis and treatment effect.

[0037] Referring to FIG1 , an embodiment of the present application provides an auxiliary fixing device for endoscope inspection, which can be used to clamp and fix the endoscope body during the colonoscopy diagnosis and treatment process to free the operator's hands. In the embodiment of the present application, only the case where the auxiliary fixing device for endoscope inspection is used to fix the colonoscope is introduced as an example. It can be understood that in some other embodiments, the auxiliary fixing device for endoscope inspection can also be used to fix the endoscope body of other endoscopes, rather than being limited to fixing the colonoscope.

[0038] Specifically, the endoscopic examination auxiliary fixing device includes a base 1, a connecting component 2 and a fixing component 3. The base 1 can be fixed to a treatment table (not shown) with the help of the connecting component 2. The fixing component 3 is installed on the base 1 and is used to fix the colonoscope to achieve effective fixation of the scope body.

[0039] As shown in FIG. 2 , the base 1 is constructed as a plate-like structure, and the base 1 includes a mounting surface 11 and a fixing surface 12 arranged opposite to each other, and the mounting surface 11 and the fixing surface 12 are both end surfaces with larger areas on the base 1. The above-mentioned connecting component 2 is installed on the fixing surface 12, and is used to fix the base 1 to the diagnosis and treatment table, and the fixing component 3 is installed on the fixing surface 12, and is arranged opposite to the connecting component 2.

[0040] Specifically, the fixing component 3 includes a palm portion 31 and a finger portion 32. The finger portion 32 is hinged to the palm portion 31 and can be surrounded by the palm portion 31 to form a fixing interval 6 for the colonoscope to pass through. After the colonoscope is passed through the fixing interval 6, it can be clamped by the finger portion 32 and abut against the surface of the palm portion 31, thereby fixing the scope body.

[0041] In the embodiment of the present application, the palm portion 31 is configured to be similar to a "palm", and the finger portion 32 is configured to be similar to a "fingers". When the mirror body needs to be fixed, the "fingers" are bent toward the "palm" to enclose the above-mentioned fixing area 6, thereby achieving the clamping operation of the mirror body.

[0042] 1 and 2, the finger portion 32 includes a plurality of sequentially connected clamping segments 321, and any two adjacent clamping segments 321 are connected in a hinged manner to facilitate opening and closing of the above-mentioned fixed interval 6. In the embodiment of the present application, the clamping segment 321 is constructed to be similar to a "knuckle" structure.

[0043] Specifically, when the scope body needs to be fixed, the operator applies a force to the clamping section 321 in the direction away from the palm 31, so that the finger portion 32 opens in the direction away from the palm 31. The operator places the scope body on the palm 31, and then applies a force to the clamping section 321 in the direction of the palm 31, so that the finger portion 32 is tightened in the direction of the palm 31, thereby fixing the scope body. When the colonoscope needs to be removed, the operator applies a force to the clamping section 321 in the direction away from the palm 31, so that the finger portion 32 opens again in the direction away from the palm 31. The overall operation is convenient and quick.

[0044] In addition, in order to improve the stability of the fixing component 3 on the mirror body, in some embodiments, the finger portion 32 is set to be multiple. In order to better fit the "hand" shape, the finger portion 32 in the embodiment of the present application is set to be four, corresponding to the index finger, middle finger, ring finger and little finger of the human hand respectively. The four finger portions 32 are installed on the palm portion 31 at intervals, and the palm portion 31 is enclosed to form the above-mentioned fixing interval 6 to improve the stability of the mirror body, thereby reducing the possibility of abnormal displacement of the mirror body during diagnosis and treatment.

[0045] 1 and 3 , in some other embodiments, in order to further improve the stability of the fixing operation of the fixing assembly 3 on the lens body, the fixing assembly 3 further includes a plurality of reset members 34 , and the reset members 34 are arranged in a one-to-one correspondence with the clamping sections 321 .

[0046] Specifically, the reset member 34 is arranged at the "joint part" of the "human hand" to apply a pre-tightening force to the clamping section 321 that is offset toward the palm 31, so that the finger portion 32 always has a tendency to bend toward the "palm", thereby enhancing the gripping force applied to the mirror body, so as to further improve the stability of the mirror body during diagnosis and treatment.

[0047] Continuing to refer to FIG. 3 , in the embodiment of the present application, the reset member 34 may be a torsion spring. The two clamping sections 321 are hinged to each other or the clamping section 321 and the palm portion 31 are hinged to each other, one end of the torsion spring is fixed to one of the clamping sections 321, and the other end is fixed to the palm portion 31 or the other clamping section 321. The reset member 34 always applies a driving force toward the “palm” direction to the clamping section 321, so as to always bend the finger portion 32 toward the “palm” direction.

[0048] Continuing to refer to FIG. 1 and FIG. 2 , in order to further improve the stability of the fixing assembly 3 in fixing the mirror body, in some embodiments, the fixing assembly 3 further includes a thumb portion 33 hinged to the palm portion 31, and the thumb portion 33 is arranged corresponding to the finger portion 32, and is used to cooperate with the palm portion 31 to support the mirror body when fixing the mirror body. In actual operation, the thumb portion 33 can cooperate with the finger portion 32 to clamp the mirror body to achieve clamping and fixing of the mirror body, thereby further improving the stability of fixing the mirror body.

[0049] In the embodiment of the present application, the thumb portion 33 is also constructed to be similar to a "finger" structure to correspond to the thumb of a human hand. In the embodiment of the present application, the endoscope inspection auxiliary fixing device is overall constructed to be similar to a human hand structure, which is used to replace the operator to fix the endoscope body during the diagnosis and treatment process, effectively freeing the operator's hands and simplifying the complexity of the diagnosis and treatment operation.

[0050] Specifically referring to FIG. 2 , in some embodiments, the fixing device further includes a buffer layer 5 mounted on the fixing assembly 3, and the buffer layer 5 is arranged along the periphery of the fixing section 6. In the embodiment of the present application, the buffer layer 5 is made of a flexible material, which can be any one of silicone, rubber, and sponge, and is not limited here. The buffer layer 5 is bonded to the palm portion 31, the finger portion 32, and the thumb portion 33 to abut against the surface of the mirror body, so as to achieve soft contact between the mirror body and the fixing assembly 3, thereby protecting the colonoscope.

[0051] Furthermore, in some other embodiments, the fixing device further includes a protective sleeve (not shown), which is coated on the periphery of the fixing component 3 to isolate the fixing component 3 from the colonoscope. On the one hand, it can reduce the direct contact between the colonoscope and the fixing component 3 during the diagnosis and treatment process, and reduce the external contamination of the colonoscope; on the other hand, the protective sleeve is coated on the periphery of the fixing component 3, which can protect the buffer layer 5, so as to reduce the contamination of the buffer layer 5 by the medical waste liquid generated during the diagnosis and treatment process.

[0052] In the embodiment of the present application, the protective cover can be a common medical glove, which has the advantages of easy material acquisition and low cost. Moreover, after a single diagnosis and treatment, the operator can directly discard the used medical gloves and replace them with new ones, and then put the fixture into the next diagnosis and treatment operation, which can effectively solve the problem of time waste caused by repeated disinfection of the fixture.

[0053] As shown in combination with Figures 1 and 3, in some other embodiments, the fixing assembly 3 also includes a plurality of linkage members 35, and the linkage members 35 are movably connected between any two adjacent finger portions 32, so that a finger portion 32 can be driven to move by any other adjacent finger portion 32, so that each "fingers" of the fixing device can synchronously complete the opening or grasping action, simplifying the process of the operator adjusting the opening and closing state of the finger portion 32.

[0054] Specifically, the linkage member 35 includes a connecting portion 351 configured in a strip shape and a movable portion 352 connected to both ends of the connecting portion 351, and the movable portion 352 is configured in a spherical shape. A receiving space 3211 for the movable portion 352 to be embedded is arranged on the side of the finger portion 32, and the movable portion 352 is rotatably installed in the receiving space 3211. The inner wall of the receiving space 3211 limits the movable portion 352, so that the movable portion 352 is limited to rotate in the receiving space 3211.

[0055] Furthermore, in order to reduce the influence of the linkage member 35 on the normal bending movement of the finger portion 32, the connection portion 351 in the embodiment of the present application can be a bundling rope or a rubber rope, and the connection portion 351 is connected to the movable portion 352 by bundling or bonding. In the embodiment of the present application, the bundling method is preferably used to achieve a detachable connection with the movable portion 352, so that the operator can assemble and adjust the position and number of the finger portion 32 by himself.

[0056] It is understandable that in the above embodiment, the corresponding protective cover used should be designed as a four-finger parallel structure to adapt to the structural design of the linkage parts 35 connected between adjacent finger parts 32.

[0057] As shown in Figures 2 and 4, in some embodiments, the connecting component 2 includes a seal 21 installed on the base 1. The seal 21 in the embodiment of the present application is specifically a sealing ring bonded to the fixed surface 12. The sealing ring is arranged along the periphery of the fixed surface 12, and the inner ring of the seal 21 and the mounting surface 11 enclose a negative pressure zone 7.

[0058] Before performing diagnosis and treatment operations, the operator moves the base 1 to a suitable position according to actual operation requirements, so that the fixing surface 12 of the base 1 faces the smooth surface on the treatment table, and then presses the base 1 hard to squeeze out the air in the negative pressure interval 7, so that the entire fixing device is adsorbed on the treatment table to adapt to different requirements for the installation position of the fixing device in different diagnosis and treatment situations.

[0059] As shown in FIG5 , in some other embodiments, the base 1 further includes a ventilation channel 13, which runs from the mounting surface 11 to the fixing surface 12 to be connected to the negative pressure interval 7 mentioned above, so as to discharge the gas in the negative pressure interval 7 during the pressing process. In addition, the connecting assembly 2 further includes a blocking member 22, which can be adapted to block the ventilation channel 13 after the exhaust is completed, so as to ensure that the negative pressure interval 7 always maintains a negative pressure state during the diagnosis and treatment process, thereby improving the stability of the fixing device.

[0060] Furthermore, in some other embodiments, the connecting component 2 also includes a one-way valve 23 installed in the air permeable channel 13. In the embodiment of the present application, the one-way valve 23 can only allow gas to flow out from the negative pressure interval 7, so as to prevent external air from entering the negative pressure interval 7 through the air permeable channel 13, thereby further improving the stability of the connection between the fixing device and the treatment table.

[0061] It is understandable that in order to ensure a reliable connection between the fixture and the treatment table, the weight of the fixture needs to be reduced as much as possible. Therefore, in the embodiment of the present application, the base 1 also includes an expansion zone 14, which runs through the above-mentioned mounting surface 11 and is connected between the air permeable channel 13 and the negative pressure zone 7 to reduce the weight of the base 1. In addition, the provision of the expansion zone 14 can also effectively expand the size of the space with negative pressure inside the base 1, thereby further improving the reliability of the connection between the fixture and the treatment table.

[0062] Continuing to refer to FIG. 1 and FIG. 2 , in some embodiments, the fixing device further includes an adjusting component 4 for adjusting the angle of the fixing component 3 , and the adjusting component 4 is installed between the fixing component 3 and the base 1 , so that the fixing component 3 can be rotatably installed on the mounting surface 11 of the base 1 .

[0063] In the embodiment of the present application, the adjustment component 4 is a common spherical joint, and the adjustment component 4 includes a rotation axis G1. The fixed component 3 can rotate around the rotation axis G1 relative to the mounting surface 11 to achieve pitch angle adjustment of the fixed component 3, so that the fixing device can adapt to more diagnosis and treatment needs.

[0064] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
