Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an oral mirror which is convenient for disassembly. Background Art

[0002] As is well known, an oral mirror is an essential medical device in the process of oral examination. Doctors can clearly examine each surface of a patient's teeth through the reflection of a reflector at the top of the oral mirror, so as to make a more accurate diagnosis of the patient's oral condition. Moreover, with the development of technology, there appears an oral mirror integrated with a camera module in the existing market. The camera module can record the image reflected by the reflector. Through the image recorded by the camera module, doctors can examine the patient's oral cavity more intuitively and clearly.

[0003] For example, an intelligent oral endoscope and an intelligent oral endoscope assembly provided by an existing patent (application number: CN201720124926.0). The endoscope main body has a hollow shell. The lower end of the shell is a holding part for hand-held, and the detection part at the upper end of the shell is provided with a camera module. The camera module includes a camera for collecting images or pictures. A wireless communication module for communicating with an external display device is arranged in the shell. The wireless communication module transmits the video or picture collected by the camera module to the display device through a wireless connection method.

[0004] However, as an oral medical device, in order to avoid cross-infection, strict cleaning and disinfection are required after each use. The detection part and the holding part of the oral endoscope provided by the above solution are integrally formed, and the detection part cannot be detached separately for cleaning or replacement, resulting in the need to clean and disinfect the whole oral endoscope after each use, which is rather inconvenient in operation. Summary of the Invention

[0005] In view of the above defects or deficiencies in the prior art, it is expected to provide an oral mirror which is convenient for disassembly. By detachably arranging between the oral mirror body and the handle, the oral mirror body can be detached separately for cleaning, disinfection or replacement, and the operation is simple. Moreover, a first circuit board and a second circuit board are respectively arranged on the oral mirror body and the handle. The first circuit board and the second circuit board are docked or separated with the installation and disassembly between the oral mirror body and the handle, which not only realizes the transmission and storage of the information collected by the camera module, but also does not affect the installation and disassembly between the oral mirror body and the handle, and is rather convenient to use.

[0006] The effect of the utility model is realized as follows:

[0007] The present application provides an oral endoscope that is conducive to disassembly, including an oral endoscope body and a handle that can be disassembled from each other. The oral endoscope body integrates a camera module configured to collect the image reflected by the reflector. A first circuit board is further provided at the rear end of the oral endoscope body, and the first circuit board is configured to store the information collected by the camera module. The handle is a hollow shell-like structure, and a first accommodation cavity is formed in its hollow part. A second circuit board is also provided in the first accommodation cavity. A first insertion interface is hollowed out at the front end of the handle, and the first insertion interface faces the second circuit board. When the oral endoscope body is connected to the handle, the first circuit board is docked to the second circuit board through the first insertion interface, and the second circuit board is configured to receive and store the information stored by the first circuit board.

[0008] Further, a guiding structure is provided between the oral endoscope body and the handle. The guiding structure includes a guiding part and a guiding groove that are engaged with each other. The guiding part is provided at one of the rear end of the oral endoscope body and the front end of the handle, and the guiding groove is opened at the other of the rear end of the oral endoscope body and the front end of the handle. The length of the guiding part is longer than that of the first circuit board. When the guiding part is inserted into the guiding groove, the first circuit board faces the first insertion interface, and no additional positioning operation is required, so that the installation operation of the oral endoscope body is more stable and convenient.

[0009] Further, the top end and the left and right ends of the oral endoscope body extend backward to form a guiding part, so that the cross-section of the guiding part is in a U-shaped structure, and the upper end and the left and right ends of the handle are correspondingly recessed to form a guiding groove. Limited by the guiding part, the oral endoscope body cannot deflect upward and to the left and right during the docking process, and the guiding is more accurate, so that the docking operation between the oral endoscope body and the handle is more convenient.

[0010] Further, the oral endoscope body is a hollow shell-like structure, and a second accommodation cavity is formed in its hollow part. The front end of the first circuit board penetrates into the second accommodation cavity, and the first circuit board is detachably connected to the oral endoscope body by means of screw connection. This makes the installation and disassembly operations of the first circuit board relatively simple.

[0011] Further, two symmetrically arranged plug-in parts protrude from the rear end of the oral endoscope body. A second insertion interface is hollowed out at the front end of the handle, and the second insertion interface communicates with the first accommodation cavity. The two plug-in parts are inserted into the handle through the second insertion interface, and the plug-in parts and the inner wall of the handle are connected by a buckle structure. The buckle structure includes a first clamping head provided at the top end of the plug-in part and a first clamping groove opened on the inner wall of the handle. The plug-in part has the ability of elastic deformation, so that the first clamping head can be clamped into or disengaged from the first clamping groove by means of the elastic deformation of the plug-in part, and thus the oral endoscope body is detachably arranged on the handle. The plug-in parts at the rear side of the oral endoscope body are connected to the inner wall of the handle through the buckle structure, and the installation and disassembly between the oral endoscope body and the handle are realized through the elastic deformation of the plug-in parts, with convenient operation and simple structure.

[0012] Furthermore, a first sliding groove is formed at the interval between the two plug-in parts, and a locking piece is connected to the first sliding groove, with the left and right ends of the locking piece abutting against the plug-in parts on the left and right sides, and the locking piece can slide forward and backward along the length direction of the plug-in part; the plug-in part has a switchable locking state and an active state. In the active state, the locking piece slides forward to a position close to the oral mirror body, and the front end of the plug-in part can be deformed under the influence of external force, and drive the first clamping head to disengage from the first clamping groove, so that the oral mirror body and the handle can be separated from each other; in the locked state, the locking piece slides backward to a position close to the handle, and the left and right ends of the locking piece abut against the front ends of the two plug-in parts, so that the plug-in part cannot be deformed, and the first clamping head cannot be disengaged from the first clamping groove, thereby making the oral mirror body and the handle relatively fixed. Only by sliding the locking piece forward and backward can the deformation of the plug-in part be restrained or avoided, and the oral mirror body and the handle can be adjusted to lock or separate each other, making the locking operation between the two very simple and convenient.

[0013] Furthermore, the oral mirror body is a hollow shell-like structure, wherein the hollow portion forms a second accommodating cavity, the front end of the oral mirror body is provided with a first avoidance opening, the locking member passes through the first avoidance opening and slides in the first accommodating cavity and the second accommodating cavity; the second accommodating cavity is provided with a stopper, the middle part of the stopper is recessed and provided with a second sliding groove which passes through the front and back, and a limiting portion is provided in the second sliding groove; the locking member includes a stopper portion at the top for abutting against the plug-in portions on both sides, a plurality of cantilevers protruding from the rear side of the stopper portion, the cantilevers pass through the second sliding groove and fit the limiting portion; The arm has elastic deformation capability, and a limiting mechanism is provided between the cantilever and the stop portion, the limiting mechanism comprising a second clamping head provided at the front end of the cantilever and a second slot correspondingly recessed and provided in the limiting portion; when the plug-in portion is in a locked state, the second clamping head is clamped into the second slot, so that the cantilever is positioned at the limiting portion, thereby driving the locking member and the stop member to remain relatively fixed; when the cantilever is switched to an active state, the cantilever is deformed under the influence of an external force, so that the second clamping head is disengaged from the second slot, thereby allowing the locking member to slide back and forth relative to the stop member again. By providing the stop member, in the locked state, the second clamping head is clamped into the second slot, so that the locking member and the stop member remain relatively fixed, and the connection stability between the oral mirror body and the handle is higher; and when it is necessary to switch to the active state, it is only necessary to forcefully push the locking member forward, and the locking member can slide freely again, making the unlocking operation also relatively simple.

[0014] Further, the bottom end of the oral endoscope body is hollowed out with a second avoidance opening, the second avoidance opening communicates with the first avoidance opening, and two symmetrically arranged positioning parts are provided at a position of the second accommodation cavity close to the second avoidance opening; the stop member includes a first support part with a horizontally arranged bottom, transition parts extend upward on both the left and right sides of the first support part, and an interval between the two transition parts forms a second sliding groove, and the front ends of the two transition parts extend along the left-right direction to form second support parts; the front end of the first support part abuts against the front side wall of the second avoidance opening, and the rear end faces of the two second support parts respectively abut against the front end faces of the two positioning parts, so that the stop member is relatively fixed to the oral endoscope body in the front-rear direction. When the locking member slides back and forth, the stop member can still be fixed in the front-rear direction after being pushed by the locking member, so that the connection strength between the stop member and the oral endoscope body is higher.

[0015] Further, there is an interval in the horizontal direction between the transition parts on both sides and the left and right side walls of the second avoidance opening, and this interval forms a third sliding groove; the locking member includes an operating part with a horizontally arranged bottom, the operating part fits against the bottom end of the first support part, and connecting parts extend upward on both the left and right sides of the operating part, and the two connecting parts pass through the third sliding groove and penetrate into the second accommodation cavity and are connected to the blocking part, the operating part extends downward beyond the second avoidance opening, and the operating part is configured to be used by a user to adjust the locking member. When the user slides the operating part back and forth, the connecting parts are driven to slide back and forth in the third sliding groove, thereby driving the blocking part at its top end to slide back and forth in the first sliding groove, further improving the simplicity of the adjustment operation of the locking member.

[0016] Further, the top ends of the insertion parts on both the left and right sides extend toward the first sliding groove to form locking member limiting parts, and the locking member limiting parts are configured to prevent the locking member from detaching from the insertion parts when sliding backward. Further improve the stability of the sliding adjustment operation of the locking member.

[0017] The oral endoscope provided by the present application is conducive to disassembly. By detachably arranging the oral endoscope body and the handle, after each use by a doctor, only the oral endoscope body needs to be disassembled for cleaning and disinfection, or a new oral endoscope body can be directly replaced and then used, making the cleaning and replacement operations of the oral endoscope body relatively simple; moreover, a camera module is arranged in the oral endoscope body, and a first circuit board and a second circuit board are respectively arranged on the oral endoscope body and the handle, and the first circuit board and the second circuit board are docked or separated as the oral endoscope body and the handle are installed and disassembled, which not only realizes the transmission and storage of the information collected by the camera module, but also does not affect the installation and disassembly between the oral endoscope body and the handle, and is relatively simple to use.

A second circuit board 3b is further provided in the first accommodation cavity 201, and a first insertion opening 202 is hollowed out at the front end of the handle 2, and the first insertion opening 202 faces the second circuit board 3b; when the oral endoscope body 1 is connected to the handle 2, the first circuit board 3a is docked to the second circuit board 3b through the first insertion opening 202, and the second circuit board 3b is configured to receive and store the information stored by the first circuit board 3a.

[0032] In this embodiment, by detachably arranging the oral endoscope body 1 and the handle 2, after each use by the doctor, only the oral endoscope body 1 needs to be detached for cleaning and disinfection, or a new oral endoscope body 1 can be directly replaced and then used, making the cleaning and replacement operations of the oral endoscope body 1 relatively simple; moreover, a camera module is arranged in the oral endoscope body 1, and a first circuit board 3a and a second circuit board 3b are respectively arranged on the oral endoscope body 1 and the handle 2. The first circuit board 3a and the second circuit board 3b are docked or separated as the oral endoscope body 1 and the handle 2 are installed and detached, which not only realizes the transmission and storage of the information collected by the camera module, but also does not affect the installation and detachment between the oral endoscope body 1 and the handle 2, and is relatively simple to use.

[0033] Please refer to the attached Figures 3-4 , in some embodiments of the present application, a guiding structure is further arranged between the oral endoscope body 1 and the handle 2. The guiding structure includes a guiding portion 120 and a guiding groove 204 that are engaged with each other. The guiding portion 120 is arranged at one of the rear end of the oral endoscope body 1 and the front end of the handle 2, and the guiding groove 204 is opened at the other of the rear end of the oral endoscope body 1 and the front end of the handle 2; the length of the guiding portion 120 is longer than that of the first circuit board 3a. When the guiding portion 120 is inserted into the guiding groove 204, the first circuit board 3a is aligned with the first insertion interface 202.

[0034] In this embodiment, by arranging the guiding mechanism, when the oral endoscope body 1 is installed on the handle 2, the first circuit board 3a can be aligned with the first insertion interface 202 without additional positioning operation, so that the installation operation of the oral endoscope body 1 is more stable and simple.

[0035] Please refer to the attached Figure 4 , in some embodiments of the present application, the top end and the left and right ends of the oral endoscope body 1 extend backward to form the guiding portion 120, so that the cross section of the guiding portion 120 is in a U-shaped structure, and the upper end and the left and right ends of the handle 2 are correspondingly recessed to form the guiding groove 204.

[0036] In this embodiment, the cross section of the guiding portion 120 is in a U-shaped structure, so that when the oral endoscope body 1 is installed on the handle 2, it cannot deflect upward and to the left and right sides after being limited by the guiding portion 120, and the guiding is more accurate, thus making the docking operation between the oral endoscope body 1 and the handle 2 more simple.

[0037] Please refer to the attached Figure 10 , in some embodiments of the present application, the oral endoscope body 1 is a hollow shell-like structure, and the hollow part forms a second accommodation cavity 101. The front end of the first circuit board 3a penetrates into the second accommodation cavity 101, and the first circuit board 3a is detachably connected to the oral endoscope body 1 by means of screw connection. This makes the installation and detachment operations of the first circuit board 3a relatively simple.

[0038] Among them, the endoscope body 1 is of a split structure, including an upper housing 1a and a lower housing 1b spliced up and down. The guiding part 120 is formed by the rear end of the upper housing 1a extending backward. The first circuit board 3a is screwed to the lower end of the upper housing 1a, so that the overall assembly operation of the endoscope body 1 is relatively simple.

[0039] Please refer to the attached Figures 5-8 , in some embodiments of the present application, two symmetrically arranged plug-in parts 110 protrude from the rear end of the endoscope body 1.

The buckle structure includes a first clamping head 111 arranged at the top end of the plug-in part 110 and a first clamping groove 205 opened on the inner wall of the handle 2; the plug-in part 110 has the ability of elastic deformation, so that the first clamping head 111 can be clamped into or disengaged from the first clamping groove 205 by means of the elastic deformation of the plug-in part 110, and thus the endoscope body 1 is detachably arranged on the handle 2.

[0040] In this embodiment, the plug-in part 110 at the rear side of the endoscope body 1 is connected to the inner wall of the handle 2 through a buckle structure, and the installation and disassembly between the endoscope body 1 and the handle 2 are realized through the elastic deformation of the plug-in part 110, which is convenient to operate and has a simple structure.

[0041] Please refer to the attached Figures 5-8 , in some embodiments of the present application, a first sliding groove 112 is formed in the interval between the two plug-in parts 110, and a locking member 4 is connected in the first sliding groove 112. The left and right ends of the locking member 4 abut against the left and right plug-in parts 110 and the locking member 4 can slide back and forth along the length direction of the plug-in part 110; the plug-in part 110 has a switchable locked state and an active state. In the active state, the locking member 4 slides forward to a position close to the endoscope body 1, and the front end of the plug-in part 110 can be deformed under the influence of an external force, and drives the first clamping head 111 to disengage from the first clamping groove 205, so that the endoscope body 1 and the handle 2 can be separated from each other; in the locked state, the locking member 4 slides backward to a position close to the handle 2, and the left and right ends of the locking member 4 abut against the front ends of the two plug-in parts 110, so that the plug-in part 110 cannot be deformed and the first clamping head 111 cannot disengage from the first clamping groove 205, and thus the endoscope body 1 and the handle 2 are relatively fixed.

[0042] In this embodiment, by arranging the locking member 4 between the two plug-in parts 110 on both sides, it is only necessary to slide the locking member 4 back and forth to restrict or avoid the deformation of the plug-in part 110, and then adjust the mutual locking or separation of the endoscope body 1 and the handle 2, making the locking operation between the two very simple and convenient.

[0043] Please refer to the attached Figures 9-10 In some embodiments of the present application, the oral mirror body 1 is a hollow shell-like structure, in which the hollow part forms a second accommodating cavity 101, and a first avoidance opening 102 is opened at the front end of the oral mirror body 1, and the locking member 4 passes through the first avoidance opening 102 and slides in the first accommodating cavity 201 and the second accommodating cavity 101; the second accommodating cavity 101 is provided with a stopper 5, and the middle part of the stopper 5 is recessed and provided with a second sliding groove 501 that passes through the front and back, and a limiting portion 510 is provided in the second sliding groove 501; the locking member 4 includes a stopper 410 at the top for abutting against the plug-in portions 110 on both sides, and a plurality of cantilevers 421 protrude from the rear side of the stopper 410, and the cantilevers 421 penetrate into the second sliding groove 501 and fit the limiting portion 510; the cantilever 421 has elastic deformation capability, and a limiting mechanism is provided between the cantilever 421 and the shifting portion 410, the limiting mechanism comprising a second clamping head 422 provided at the front end of the cantilever 421 and a second clamping groove 511 correspondingly recessed and provided in the limiting portion 510; when the plug-in portion 110 is in a locked state, the second clamping head 422 is clamped into the second clamping groove 511, so that the cantilever 421 is positioned at the limiting portion 510, thereby driving the locking member 4 and the stop member 5 to remain relatively fixed; when the cantilever 421 is switched to an active state, the cantilever 421 is deformed under the influence of external force, so that the second clamping head 422 is disengaged from the second clamping groove 511, thereby allowing the locking member 4 to slide back and forth relative to the stop member 5 again.

[0044] In this embodiment, by providing a stopper 5, in the locked state, the second clamping head 422 is clamped into the second clamping groove 511 so that the locking member 4 and the stopper 5 remain relatively fixed, so that the locking member 4 cannot slide easily in the locked state, and the connection stability between the oral mirror body 1 and the handle 2 is higher; and when it is necessary to switch to the active state, it is only necessary to force the locking member 4 forward so that the cantilever 421 is deformed by the force and the second clamping head 422 is disengaged from the second clamping groove 511, and the locking member 4 can slide freely again, so that the unlocking operation is also relatively simple.

[0045] Among them, preferably, two left-right symmetrical limiting parts 410 are provided in the second sliding groove 501, and two left-right symmetrical cantilevers 421 are correspondingly provided on the rear side of the abutting part 320, so that the connection strength between the locking part 4 and the stop part 5 is higher and the stability is better.

[0046] Please refer to the attached Figures 9-10, in some embodiments of the present application, the bottom end of the oral endoscope body 1 is hollowed out with a second avoidance opening 103, the second avoidance opening 103 communicates with the first avoidance opening 102, and two symmetrically arranged positioning parts 104 are provided at a position of the second accommodation cavity 101 close to the second avoidance opening 103; the stopper 5 includes a first support part 520 with a horizontally arranged bottom, transition parts 530 extend upward on both the left and right sides of the first support part 520, and a second sliding groove 501 is formed by the interval between the two transition parts 530, and the front ends of the two transition parts 530 extend along the left-right direction to form second support parts 540; the front end of the first support part 520 abuts against the front side wall of the second avoidance opening 103, and the rear end faces of the two second support parts 540 respectively abut against the front end faces of the two positioning parts 104, so that the stopper 5 is relatively fixed to the oral endoscope body 1 in the front-rear direction.

[0047] In this embodiment, by clamping and fixing the stopper 5 and the oral endoscope body 1 in the front-rear direction, when the locking member 4 slides back and forth, the stopper 5 can still remain fixed in the front-rear direction after being pushed by the locking member 4, so that the connection strength between the stopper 5 and the oral endoscope body 1 is higher; moreover, the stopper 5 does not need to be integrally formed with the oral endoscope body 1, and the two are detachably arranged, making the assembly of the oral endoscope body 1 more convenient.

[0048] Wherein, an L-shaped baffle 140 is also screwed to the top end of the positioning part 104, the top end of the second support part 540 abuts against the horizontal part of the baffle 140 and the vertical part of the baffle 140 covers the first avoidance opening 102, and the bottom end of the second support part 540 abuts against the oral endoscope body 1, so that the stopper 5 is relatively fixed to the oral endoscope body 1 in the vertical direction.

[0049] Wherein, the first avoidance opening 102 and the second avoidance opening 103 are formed in the lower housing 1b; when assembling the oral endoscope body 1, first assemble the locking member 4 and the stopper 5 together, and then put the two into the lower housing 1b, so that the first support part 520 of the stopper 5 abuts against the front side wall of the second avoidance opening 103, and the rear end faces of the two second support parts 540 respectively abut against the front end faces of the two positioning parts 104, so that the locking member 4 and the stopper 5 are positioned in the lower housing 1b; then, cover the baffle plate 140 on the positioning part 104 and screw it in for fixation, so that the locking member 4 and the stopper 5 are fixed in the lower housing 1b; screw the first circuit board 3a to the bottom end of the upper housing 1a; finally, splice the upper housing 1a to the lower housing 1b to form a complete oral endoscope body 1; thus, the assembly operation of the oral endoscope body 1 is relatively simple.

[0050] Please refer to the appendix Figures 5-8, in some embodiments of the present application, there is a gap in the horizontal direction between the transition portions 530 on both sides and the left and right side walls of the second avoidance opening 103, and this gap forms a third sliding groove 105; the locking member 4 includes an operation portion 430 with a horizontally arranged bottom, the operation portion 430 fits against the bottom end of the first support portion 520, and connection portions 420 extend upward from both the left and right sides of the operation portion 430. The connection portions 420 on both sides pass through the third sliding groove 105 and enter the second accommodation cavity 101 and are connected to the blocking portion 410. The operation portion 430 extends downward beyond the second avoidance opening 103, and the operation portion 430 is configured for the user to adjust the locking member 4.

[0051] In this embodiment, when the user slides the operation portion 430 back and forth, the connection portion 420 is driven to slide back and forth in the third sliding groove 105, thereby driving the blocking portion 410 at its top to slide back and forth in the first sliding groove 112, further improving the simplicity of the adjustment operation of the locking member 4.

[0052] Among them, the connection portion 420 is a bent L-shaped rod, and the gap between the connection portion 420 and the operation portion 430 forms a fourth sliding groove 301.
