[0002] Rigid endoscopic surgery is a new minimally invasive method. Compared with traditional surgery, it has the advantages of less surgical trauma, faster recovery, less pain, smaller incisions and less scarring. Rigid endoscopic surgery requires the use of a camera device. After the rigid endoscope is connected to the camera device, the camera device can be used as an operating handle for the rigid endoscope, and the endoscope can be controlled by operating the camera device.

[0003] When using hard-scope cameras in different departments, the hard-scope bodies used are usually different. For example, for the laparoscope used in general surgery, the hard-scope body is larger; and for the uroscope used in urology, the hard-scope body is smaller. Therefore, in clinical practice, medical staff hope that the scope body can be simply and conveniently connected to the camera device, and hope that the connection between the scope body and the camera device can be easily disassembled and disconnected, so that the scope body can be easily replaced, so that the camera device can be compatible with the scopes of multiple departments. When the scope body is connected to the camera device, it is usually the connecting mechanism on the camera device that is connected to the scope body. Therefore, there is an urgent need for an endoscope scope connection mechanism that is easy to connect to the scope body and also easy to disassemble from the scope body. Utility Model Content

DETAILED DESCRIPTION

[0039] In the following description, a large number of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only illustrates preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described in detail.

[0040] According to one aspect of the present invention, an endoscope body connection mechanism is provided. The endoscope body connection mechanism can be used to connect the bodies of various hard scopes, such as laparoscopes or uroscopes. Figure 1 and Figure 2 The scope body 20 is detachably connected to the endoscope scope body connecting mechanism 10.

[0041] The endoscope body connection mechanism 10 may include a connection seat 100, a movable housing 200 and a clamping assembly 300. The body may be inserted into the connection seat 100 along the axial direction of the connection seat 100. The clamping assembly 300 may be used to clamp the body 20, and generally the clamping assembly 300 may clamp the proximal end of the body 20. Figure 3-11The clamping assembly 300 may include a clamping claw 310 and a clamping claw elastic member 320. The clamping claw 310 is in the clamping position (see Figure 9-11 ) and release position (see Figure 3-8 ) are movably arranged on the connecting seat 100. The clamping position refers to the position where the clamping claw 310 clamps the mirror body 20, and the releasing position refers to the position where the clamping claw 310 releases the clamping of the mirror body 20. The movement of the clamping claw 310 between the clamping position and the releasing position can be translation or rotation. For example, the clamping claw 310 can rotate between the clamping position and the releasing position, and the clamping position and the releasing position can be two angular positions of the clamping claw 310. The clamping claw elastic member 320 can be a spring or various other elastic members. The clamping claw elastic member 320 can apply an elastic force to the clamping claw 310 to keep the clamping claw 310 in the releasing position. When the claw 310 is not subjected to external force, it will be kept in the release position by the claw elastic member 320. It can be considered that the elastic force applied by the claw elastic member 320 to the claw 310 can make the claw 310 have a tendency to move toward the release position. For example, the elastic force applied by the claw elastic member 320 to the claw 310 can make the claw 310 move from the clamping position to the release position. When an external force acts on the claw 310, and the external force is sufficient to overcome the elastic force applied by the claw elastic member 320 to the claw 310, such an external force can make the claw 310 move from the release position to the clamping position. In particular, the claw 310 in the release position may not be subjected to force, that is, when the claw 310 is in the release position, the claw elastic member 320 may be in a natural state, and at this time, the claw elastic member 320 may not have an elastic force on the claw 310. When an external force acts on the claw 310 to move the claw 310 toward the clamping position, the claw elastic member 320 can be deformed to apply an elastic force to the claw 310 toward the release position. After the external force is removed, the claw 310 will return to the release position under the action of the elastic force.

[0042] The movable shell 200 is movably connected to the connecting seat 100 along the axial direction between a natural position and an operating position. The movement of the movable shell 200 relative to the connecting seat 100 may be rotation or translation. Since the movable shell 200 usually needs to surround at least a portion of the connecting seat 100, preferably, the movement of the movable shell 200 relative to the connecting seat 100 may be movement in the axial direction coaxially with the connecting seat 100 to ensure that the movable shell 200 surrounds at least a portion of the connecting seat 100. A shell elastic member 210 may be connected between the movable shell 200 and the connecting seat 100. The shell elastic member 210 may be a spring or various other forms of elastic members, and the movement of the movable shell 200 relative to the connecting seat 100 may be driven by an external force or by the elastic force applied by the shell elastic member 210 to the movable shell 200. For example, see Figure 4 and Figure 5, the shell elastic member 210 can be a linear spring, the shell elastic member 210 can be located between the connecting seat 100 and the movable shell 200, the distal end of the shell elastic member 210 can abut against the movable shell 200, and the proximal end of the shell elastic member 210 can abut against the connecting seat 100. Such a shell elastic member 210 can enable the movable shell 200 to achieve a larger stroke. The movable shell 200 can move from the natural position to the operating position under the action of an external force. The shell elastic member 210 can apply an elastic force to the movable shell 200 to keep the movable shell 200 in the natural position. The movable shell 200 will be kept in the natural position by the action of the shell elastic member 210 when not subject to an external force. It can be considered that the elastic force applied by the shell elastic member 210 to the movable shell 200 can make the movable shell 200 have a tendency to move toward the natural position, for example, the elastic force applied by the shell elastic member 210 to the movable shell 200 can make the movable shell 200 move from the operating position to the natural position. When an external force acts on the movable housing 200, and the external force is sufficient to overcome the elastic force applied by the housing elastic member 210 to the movable housing 200, such an external force can make the movable housing 200 move from the natural position to the operating position. In particular, the movable housing 200 in the natural position may not be subjected to force, that is, when the movable housing 200 is in the natural position, the housing elastic member 210 may be in a natural state, and at this time, the housing elastic member 210 may not exert an elastic force on the movable housing 200. When an external force acts on the movable housing 200 to make the movable housing 200 move toward the operating position, the housing elastic member 210 may be deformed and exert an elastic force on the movable housing 200 toward the natural position. After the external force is removed, the movable housing 200 will return to the natural position under the action of the elastic force.

[0043] As described above, when the external force applied to the claw 310 is sufficient to overcome the elastic force applied to the claw 310 by the claw elastic member 320, the claw 310 can be kept in the clamping position. The external force here can be provided by manpower or by the movable housing 200 squeezing the claw 310. When the movable housing 200 is in the natural position, the claw 310 can be squeezed to be in the clamping position. When the movable housing 200 is in the operating position, the squeezing of the claw 310 can be released, and the claw 310 can be moved to the release position.

[0044] The following is Figure 1 and Figure 2 The embodiment shown in the figure describes in detail the connection process when such an endoscope body connection mechanism 10 is used to connect the body 20. The initial state can be as follows Figure 1As shown, the scope 20 is not connected to the endoscope scope connection mechanism 10. At this time, no external force acts on the endoscope scope connection mechanism 10. The movable housing 200 is in a natural position, and the housing elastic member 210 is in a natural state and has almost no elastic effect on the movable housing 200. The movable housing 200 in the natural position squeezes the claw 310, which is equivalent to the movable housing 200 applying an external force to the claw 310. The movable housing 200 squeezes the claw 310 and the external force applied to the claw 310 is greater than the elastic force provided by the claw elastic member 320 to the claw 310 at this time, so that the movable housing 200 squeezes the claw 310 so that the claw 310 remains in the clamping position. Figure 3 , Figure 4 , Figure 5 and Figure 8 , an external force is applied to the movable shell 200, and the shell elastic member 210 is deformed, and the external force is sufficient to overcome the elastic force applied by the shell elastic member 210 to the movable shell 200, so that the movable shell 200 moves to the operating position. The movable shell 200 releases the squeeze on the claw 310, which is equivalent to the claw 310 being only subjected to the elastic force of the claw elastic member 320 at this time, so the claw 310 will move to the release position. The claw 310 in the release position can avoid the area on the connecting seat 100 used to connect the mirror body 20. The area on the connecting seat 100 used to connect the mirror body 20 can be the central area 130. At this time, the mirror body 20 can be inserted into the connecting seat 100. The external force on the movable shell 200 can then be removed, see Figures 9 to 11 , the movable housing 200 will only be affected by the elastic force of the housing elastic member 210, and will move from the operating position to the natural position. The movable housing 200 in the natural position squeezes the claw 310, which is equivalent to applying an external force toward the clamping position to the claw 310, and this external force toward the clamping position is sufficient to overcome the elastic force applied by the claw elastic member 320 to the claw 310. Therefore, the claw 310 will move to the clamping position under the squeezing of the movable housing 200, and the clamping of the scope 20 will be completed. After the clamping of the scope 20 is completed, the endoscope scope connection mechanism 10 will remain connected with the scope 20 without applying an external force, or in other words, without moving the movable housing 200 to the operating position.

[0045] The endoscope body connection mechanism 10 provided by the utility model applies an external force to the movable housing 200, so that the claw 310 is in the release position when the movable housing 200 moves to the operating position, and the body 20 can be disassembled or installed at this time. When the external force is removed, the movable housing 200 will remain in the natural position, and at the same time, the movable housing 200 squeezes the claw 310 so that the claw 310 remains in the clamping position, and the claw 310 can achieve stable clamping of the body 20, thus realizing the connection between the endoscope body connection mechanism 10 and the body 20, and this process is simple and convenient, and the connection is also very stable. When such an endoscope body connection mechanism 10 is used to connect the body 20, the connection and the disassembly and disconnection of the connection are very simple and convenient, and the endoscope body connection mechanism 10 is very stable as a whole when connected to the body 20.

[0046] In one embodiment of the present invention, see Figure 3-4 , Figure 8 and Fig.10 , the movable housing 200 may be provided with an avoidance groove 220. Figure 6 , the distal end 310a of the claw 310 has an inner side facing the center of the connection base 100 and an outer side facing away from the center of the connection base 100. The "proximal end" and "distal end" described herein are relative to the user. In the use state, the end close to the user is the proximal end, and the end away from the user is the distal end. Here, the center of the connection base 100 may refer to the central area 130 of the connection base 100. The inner side of the distal end 310a of the claw 310 is provided with a hook 313 for holding the lens 20. When the claw 310 is located at the release position, the outer side of the claw 310 extends into the avoidance groove 220. Therefore, when the movable housing 200 moves to the operating position under the action of an external force, the claw 310 can move to the release position by extending the outer side of its distal end 310a into the avoidance groove 220, and the movable housing 200 also releases the squeezing of the claw 310. Preferably, the avoidance groove 220 can have a size matching the claw 310. The claw 310 at the release position needs to avoid the area on the connection base 100 used for connecting with the mirror body 20. The area on the connection base 100 used for connecting with the mirror body 20 can usually be located in the central area 130 of the connection base 100. Therefore, when the claw 310 moves from the clamping position to the release position, at least part of the claw 310 moves outward relative to the connection base 100, and the movable shell 200 at the operating position releases the squeeze on the claw 310. Therefore, the movable shell 200 needs to avoid the part of the claw 310 that moves outward relative to the connection base 100. The setting of the avoidance groove 220 realizes the avoidance of the movable shell 200 at the operating position to the outward movement of the claw 310 relative to the connection base 100 with a simple structure. Figure 3In the illustrated embodiment, the movable housing 200 is coaxially arranged with the connecting seat 100. If the avoidance groove 220 is not provided, the avoidance of the movable housing 200 for the outward movement of the claw 310 relative to the connecting seat 100 makes the movable housing 200 have only a shorter length in the axial direction. The provision of the avoidance groove 220 allows the portion of the movable housing 200 excluding the avoidance groove 220 to have a longer length in the axial direction, thereby surrounding more portions of the connecting seat 100 and providing better protection for the connecting seat 100.

[0047] Since the endoscope body connection mechanism 10 is generally connected to the body 20, and the proximal end of the body 20 is generally circular, the connection seat 100 may be annular, and the central area 130 of the connection seat 100 may be hollow, such as Figure 5 As shown. There can be multiple clamping assemblies 300, and they are evenly distributed around the center of the connecting seat 100. The movable shell 200 can be in a ring shape surrounding the connecting seat 100 and the clamping assembly 300. In this way, the movable shell 200 can provide better protection for the connecting seat 100 and the clamping assembly 300, and the dimensions of the connecting seat 100 and the movable shell 200 in the axial direction can be smaller, and the overall device can be more compact, and it can also be suitable for the needs of more occasions. For example, as Figure 4 As shown, the claw elastic member 320 may include an annular member 321 and an elastic sheet 322. The annular member 321 may be disposed on the connection base 100, and the annular member 321 may be closer to the proximal end of the connection base 100 relative to the claw 310. The elastic sheet 322 may be bent from the annular member 321 toward the claw 310 and may abut against the tilting portion 312. A plurality of elastic sheets 322 may be held together by the annular member 321. A plurality of elastic sheets 322 may be shrapnel disposed on the annular member 321. The annular member 321 may be fixed to the connection base 100 by fasteners such as screws. Such a claw elastic member 320 occupies less space in the axial direction, thereby further making the overall device more compact, and also being applicable to the needs of more occasions.

[0048] Typically, the movable housing 200 is sleeved on the connecting seat 100. The avoidance groove 220 may be recessed from the inner circumference of the movable housing 200 to the outer circumference. In one embodiment of the present invention, the avoidance groove 220 penetrates the movable housing 200 in the radial direction, and the avoidance groove 220 penetrates to the far end of the movable housing 200 in the axial direction. This facilitates processing. However, the present application does not exclude the situation that the avoidance groove 220 does not penetrate the movable housing 200 in one or both of the radial direction and the axial direction.

[0049] In one embodiment of the present invention, see Figure 8 and Fig.10, the avoidance groove 220 may have a first groove wall 221. A self-locking protrusion 2212 may be provided at the edge of the first groove wall 221 facing the claw 310. A self-locking recess 311 may be provided on the claw 310. When the claw 310 is in the release position, the self-locking recess 311 and the self-locking protrusion 2212 may be engaged with each other so that the claw 310 can be kept in the release position. The self-locking recess 311 and the self-locking protrusion 2212 may be in any form that is easy to engage with each other and keep the claw 310 in the release position. In the illustrated embodiment, the self-locking protrusion 2212 has a tip, and the tip can be inserted into the groove of the self-locking recess 311. As described above, the claw 310 in the release position may not be subject to external force, and at this time the movable housing 200 is in the operating position and the compression of the claw 310 is released, but because the housing elastic member 210 is deformed at this time, the housing elastic member 210 exerts an elastic force on the movable housing 200, so that the movable housing 200 has a tendency to move toward the natural position, that is, the movable housing 200 has a tendency to continue to compress the claw 310. In the process of the endoscope body connection mechanism 10 being used to connect with the body 20, when the body 20 is inserted into the connection seat 100, the movable housing 200 needs to be kept in the operating position for a period of time, and this period of time can be used to insert the body 20 into the central area 130 of the connection seat 100 and adjust the position of the body 20. In order to keep the movable housing 200 in the operating position for a period of time, an external force needs to be applied to the movable housing 200, and the external force needs to be sufficient to overcome the elastic force applied by the housing elastic member 210 to the movable housing 200. If the external force is provided by manpower, it will cause more labor during the operation. The self-locking recess 311 and the self-locking protrusion 2212 are arranged so that the self-locking recess 311 and the self-locking protrusion 2212 can be engaged with each other so that the claw 310 can be kept in the release position, and the claw 310 can also keep avoiding the central area 130 of the connection seat 100. At the same time, since the self-locking recess 311 and the self-locking protrusion 2212 are engaged with each other so that the claw 310 is stably kept in the release position, the claw 310 can in turn exert a force on the movable housing 200, so that the movable housing 200 can overcome the elastic force provided by the housing elastic member 210 and remain in the operating position. When such an endoscope body connection mechanism 10 is used to connect with the body 20, in the process of connecting the body 20 to the endoscope body connection mechanism 10, it is not necessary to spend manpower to keep the movable housing 200 in the operating position, and the connection process is simpler, more convenient, and more labor-saving.

[0050] See also Figure 6 , Figure 8 and Fig.10, the proximal end of the claw 310 can be bent toward the center of the connection seat 100 and form a tilting portion 312. The tilting portion 312 can extend a certain length toward the central area 130 of the connection seat 100, and the distal end of the claw 310 can be provided with a hook portion 313, and the mirror body 20 can abut against the tilting portion 312, so that the self-locking protrusion 2212 and the self-locking recess 311 can be disengaged, and the claw 310 can move from the release position to the clamping position, and when the claw 310 is in the clamping position, the hook portion 313 can clamp the mirror body 20. Specifically, the mirror body of the mirror body 20 can include a portion similar to a cone, so as to have an inclined surface portion and an end surface portion in the axial direction, and when the claw 310 is in the clamping position, the hook portion 313 can contact the inclined surface portion on the mirror body of the mirror body 20 at the distal end, and the tilting portion 313 can contact the end surface portion on the mirror body of the mirror body 20 at the proximal end. When the scope 20 is connected to the scope connection mechanism 10 of the endoscope, the scope 20 can abut against the tilting portion 312, so that the tilting portion 312 moves toward the proximal end, thereby driving the self-locking recess 311 to disengage from the mutual engagement with the self-locking protrusion 2212. After the mutual engagement between the self-locking recess 311 and the self-locking protrusion 2212 is disengaged, there is no external force to keep the claw 310 in the released position, and the movable housing 200 has the ability to move toward the natural position under the action of the housing elastic member 210. The movable housing 200 presses against the claw 310, and the mirror body 20 presses against the tilting portion 312. The claw 310 moves from the release position to the clamping position. The claw 310 at the clamping position and the hook portion 313 clamp the mirror body 20, and further enable the mirror body 20 to stably press the tilting portion 312. Thus, the claw 310 overcomes the elastic force of the claw elastic member 320 under the pressure of the movable housing 200 and the mirror body 20, and remains in the clamping position. The provision of the tilting portion 312 makes it easier for the self-locking recess 311 to disengage from the mutual engagement with the self-locking protrusion 2212.

[0051] Specifically, see Figure 6 and Fig.10 The first groove wall 221 is inclined toward the center of the connection seat 100 and the distal end to form a self-locking protrusion 2212. The self-locking protrusion 2212 formed in this way is equivalent to a tip on the side of the first groove wall 221 close to the center of the connection seat 100; the side of the claw 310 close to the movable housing 200 can protrude along the inclined direction of the self-locking protrusion 2212 to form a self-locking recessed portion 311. The self-locking recessed portion 311 can actually be regarded as a groove on the side of the claw 310 close to the movable housing 200. The tip is inserted into the groove, that is, the self-locking protrusion 2212 and the self-locking recessed portion 311 are mutually engaged. Such a self-locking protrusion 2212 and the self-locking recessed portion 311 have a simple structure, are easy to implement, and are stable after being mutually engaged.

[0052] To summarize the above operation process, the endoscope body connection mechanism 10 is initially in Figure 1 In the state shown, the scope 20 is not connected to the endoscope scope connecting mechanism 10, and no external force acts on the endoscope scope connecting mechanism 10. The movable shell 200 is in a natural position. The movable shell 200 in the natural position squeezes the claw 310 to make the claw 310 in a clamping position. At this time, the raised portion 312 contacts the claw elastic member 320 and causes the claw elastic member 320 to deform. The claw elastic member 320 makes the claw 310 tend to move toward the release position. Subsequently, an external force is applied to the movable shell 200, so that the movable shell 200 moves from the natural position to the operating position, and the movable shell 200 releases the squeeze on the claw 310, and the claw 310 forms an avoidance to the central area 130 of the connecting seat 100. At least a portion of the claw 310 will move toward the outside of the connecting seat 100, so that at least a portion of the claw 310 will enter the avoidance groove 220. Since a self-locking recess 311 is formed on the side of the claw 310 close to the movable shell 200, a self-locking protrusion 2212 is formed on the first groove wall 221 of the avoidance groove 220, which is away from the center of the connecting seat 100 and is inclined toward the proximal end. The self-locking protrusion 2212 will be stuck in the self-locking recess 311, and the self-locking protrusion 2212 and the self-locking recess 311 are engaged with each other so that the claw 310 remains in the released position. At this time, the external force on the movable housing 200 can be removed, and the claw 310 can still be kept in the release position, and the claw 310 exerts a force on the movable housing 200 so that the movable housing 200 is kept in the operating position. Then the mirror body 20 is inserted into the connecting seat 100, and the mirror body 20 will abut against the tilting portion 312, so that the claw 310 moves toward the holding position. When the mirror body 20 abuts against the tilting portion 312 and the housing elastic member 210 moves the movable housing 200 toward the natural position, the movable housing 200 gradually squeezes the claw 310. Under such a double influence, the claw 310 will be forced to move to the holding position, and the hook 313 will hold the mirror body 20.

[0053] In another set of embodiments, see Fig.12 and Fig.13The avoidance groove 220' on the movable housing 200' may have a second groove wall 221'. The edge of the second groove wall 221' close to the center of the connecting seat 100' may be provided with a chamfer 2211'. When the claw 310' is in the released position, the outer side of the distal end of the claw 310' can abut against the chamfer 2211'. When the claw 310' moves from the released position to the holding position, the part of the claw 310' abutting against the chamfer 2211' can move along the chamfer 2211'. In this way, the claw 310' moves from the released position to the holding position more smoothly, and the overall device is smoother when in use. When the external force is removed and the movable housing 200 moves from the operating position to the natural position, and thus the claw 310' moves from the released position to the holding position, no jamming will occur. Moreover, the contact surface between the claw 310' and the chamfer 2211' is relatively large. Even if the claw 310' moves back and forth against the chamfer 2211', the wear is relatively small, so that the service life of the overall device is longer. Moreover, the chamfer 2211' has almost no constraint on the movement of the claw 310', so that the range of movement of the claw 310' can be larger.

[0054] Fig.12 and Fig.13 The embodiment shown is Figure 3-11 The same or similar parts of the illustrated embodiments are provided with the same reference numerals and will not be described in detail herein for the sake of brevity.

[0055] In one embodiment of the present invention, see Figures 3 to 8 The connection base 100 may be provided with a notch 110 corresponding to the claw 310, and the claw 310 at the release position may pass through the notch 110 and abut against the movable housing 200. The claw 310 moves relative to the connection base 100 at the notch 110, which can save more space for the overall device, making the overall device more compact and applicable to more occasions.

[0056] Exemplarily, the claw 310 is pivotally connected to the connection seat 100 around a pivot axis between a clamping position and a release position. The claw 310 moves between the clamping position and the release position by pivoting, which can reduce the space required during the movement, thereby making the structure of the endoscope body connection mechanism 10 more compact.

[0057] In one embodiment, Figure 6As shown, the claw 310 has a pivot shaft 314, and the side wall of the pivot shaft 314 includes a third surface 314a and a fourth surface 314b opposite to each other, and a first arc surface 314c and a second arc surface 314d connected between the third surface 314a and the fourth surface 314b. The first arc surface 314c and the second arc surface 314d are opposite to each other and are both located on a cylindrical surface with the pivot axis as the axis. The pivot shaft 314 has a first outer diameter (illustrated distance A) between the first arc surface 314c and the second arc surface 314d, and has a second outer diameter (illustrated distance B) between the third surface 314a and the fourth surface 314b, and the second outer diameter B can be smaller than the first outer diameter A. The connection seat 100 can be provided with a slit 120 for accommodating the pivot shaft 314, and the slit 120 can extend along the pivot axis. The slit 120 may be provided with an opening 123 on the outer surface of the connecting seat 100 on one side of the pivot axis, and the width of the opening 123 (the distance C shown in the figure) may be greater than the second outer diameter B and may be less than the first outer diameter A. The inner surface of the slit 120 cooperates with the first arc surface 314c and the second arc surface 314d so that the pivot shaft 314 can pivot in the slit 120. The first groove 121 and the second groove 122 extending along the pivot axis may be respectively provided on the two opposite sides forming the slit 120. The first arc surface 314c and the second arc surface 314d cooperate with the first groove 121 and the second groove 122 respectively so that the pivot shaft 314 can pivot in the space defined by the first groove 121 and the second groove 122.

[0058] During installation, Figure 6 In the placement orientation, the claw 310 can be laid flat first. Since the second outer diameter B between the third surface 314a and the fourth surface 314b can be smaller than the width C of the opening 123, the pivot shaft 314 can be inserted into the slit 120 after laying flat. Then, the claw 310 is rotated to a vertical state, so that the first arc surface 314c and the second arc surface 314d enter the first groove 121 and the second groove 122 respectively, and cooperate with the first groove 121 and the second groove 122. Finally, the movable housing 200 is sleeved on the connecting seat 100 and covers the opening 123 of the slit 120. The claw 310 cannot return to the flat state under the restriction of the movable housing 200, so the pivot shaft 314 can be restricted in the slit 120. This design of the slit 120 is very convenient to install and can be easily processed on the connecting seat 100.

[0059] The claw 310 and the pivot shaft 314 can be integrally formed and fixedly connected together, or they can be separately produced and processed and then fixedly connected together by various forms such as clamping, welding or threaded connection. When the pivot shaft 314 rotates relative to the slit 120, the claw 310 also rotates relative to the slit 120, that is, the claw 310 can rotate relative to the connecting seat 100, thereby, the movement of the claw 310 between the clamping position and the release position can be rotation, and the clamping position and the release position can be two angular positions of the claw 310 relative to the rotation axis of the pivot shaft 314. The movement of the claw 310 between the clamping position and the release position is achieved by rotation, and the overall structure is very simple, which further saves the space occupied by the overall device in the axial direction, making the overall device more compact and applicable to the needs of more occasions.

[0060] Exemplarily, the movable housing 200 is sleeved on the connection base 100 from the distal end, and the inner circumference of the distal end of the movable housing 200 has abutment 201. The connection base 100 is provided with a step surface 101. When the movable housing 200 is in the operating position, the abutment 201 abuts against the step surface 101. An annular groove 202 is provided on the inner circumference of the proximal end of the movable housing 200. The endoscope body connection mechanism 10 also includes a clamp 400 with a notch, see Figure 4 The notch allows the clamp 400 to have a certain deformation ability, making its diameter smaller, so that it can be installed in the annular groove 202, such as Figure 7 As shown. The limit of the movable housing 200 in the natural position can be provided by the clamp 400, that is, when the movable housing 200 is in the natural position, the proximal end of the connecting seat 100 can be against the clamp 400. Optionally, the limit of the movable housing 200 in the natural position can be provided by the housing elastic member 210, that is, when the movable housing 200 is in the natural position, the housing elastic member 210 is in a natural state, and a certain gap can be allowed between the proximal end of the connecting seat 100 and the clamp 400. Since the abutting portion 201 and the step surface 101 used to keep the movable housing 200 always sleeved on the connecting seat 100, as well as the annular groove 202 and the clamp 400 are all located inside the movable housing 200, the outer surface of the endoscope body connecting mechanism 10 can be ensured to be smooth, which is very beneficial for surgical instruments.

[0061] According to another aspect of the present invention, a camera device is also provided. Fig.14As shown, the camera device includes any one of the endoscope body connection mechanisms 10 described above. In addition, the camera device may also include a handheld mechanism 30, and the endoscope body connection mechanism 10 may be connected to the handheld mechanism 30. The handheld mechanism 30 may be provided with one or more of an imaging unit, a refractive element, a focusing mechanism, an angle adjustment mechanism, etc. The imaging unit is used to convert the optical signal transmitted by the scope 20 into an electrical signal. The refractive element can change the angle between the axis of the scope 20 and the axis of the imaging unit. The focusing mechanism is used to adjust the imaging clarity of the imaging unit. The angle adjustment mechanism can be connected between the handheld mechanism 30 and the endoscope body connection mechanism 10, and is used to enable the endoscope body connection mechanism 10 to rotate around the axis of the scope.

[0062] According to another aspect of the present invention, an endoscope is provided. Figure 1 and Figure 2 The endoscope may include a scope 20 and any camera device as described above. The clamping assembly 300 may clamp the scope 20 so that the scope 20 may be connected to the endoscope scope connection mechanism 10. In such an endoscope, the connection and disconnection between the scope 20 and the endoscope scope connection mechanism 10 are very simple and convenient, and the endoscope scope connection mechanism 10 is very stable when connected to the scope 20.
