In actual application, a detachable connection mode can also be used according to actual needs to meet the needs of actual scenes.

[0105] The carrier 35 is preferably in a U-shaped structure, and has a wire channel 351 inside for the cable to pass through, avoiding the cable from being exposed, and facilitating the appearance and avoiding the interference of the operation of each component.

[0106] The side wall of the first carrier arm 352 and the second carrier arm 353 each has a detachable first cover plate 354, and the carrier 35 has a detachable second cover plate 355 on both sides of the connecting rod 351, which can be used for installing and maintaining the circuit when being detached.

[0107] The first carrier arm 352 has a groove 3521 matching the end of the endoscope handle 4, which can match the shape of the endoscope handle 4 and limit the position of the endoscope handle 4, making the endoscope handle 4 more stable and not shaking.

[0108] The assembly position is configured to have a support shell 311 arranged on the support seat 31 and a flip cover 312, one side of the flip cover 312 is hinged to one side of the support shell 311, and the other side of the flip cover 312 can rotate freely around the hinge end. When in the open mode, the endoscope handle 4 can be placed on the support shell 311 or taken out from the support shell 311. During the conversion from the open mode to the fixed mode, the other side of the flip cover 312 can rotate around the hinge end and be locked on the other side of the support shell 311. At this time, the endoscope handle 4 cannot be taken out from the assembly position, and the flip cover 312 can tightly hold the endoscope handle 4 when being locked on the support shell 311, ensuring that the endoscope handle 4 does not move during the operation. The support shell 311 and the flip cover 312 are in a conical structure when being clamped, and the small end is opposite to the groove 3521. The small end of the support shell 311 is a half-horn structure 3112.

[0109] In this embodiment, the clamping and locking mode of the support shell 311 and the flip cover 312 is preferably a structure of elastic clamping on the groove table. Specifically, as shown in Figure 2 、 Figure 3 The support shell 311 has a clamping groove 3111, and the side of the flip cover 312 away from the hinge end has a locking plate 3121. The middle part of the locking plate 3121 is hinged to the flip cover 312, the upper part of the locking plate 3121 is elastically matched with the support shell 311 through a spring pin 3122, and the lower part of the locking plate 3121 is in an arc structure. The edge of the arc structure matches the clamping groove 3111. When the upper part of the locking plate 3121 is pressed, the edge of the lower part of the locking plate 3121 is separated from the clamping groove 3111, and at this time the flip cover 312 can be opened. When the upper part of the locking plate 3121 is released, the lower edge 3123 of the locking plate of the lower part of the locking plate 3121 is inserted into the clamping groove 3111 under the action of the elasticity of the spring pin 3122, and at this time the flip cover 312 cannot be opened and is in the fixed mode.

[0110] Further, the support shell 311 and the flip cover 312 can be engaged in various ways such as a lock, an elastic extrusion engagement, a latch lock, and the like, which will not be described herein.

The bottom of the forceps lifting sleeve 41 is connected to a rotating disc 44 on the handle 4 of the endoscope. The connecting block 33 drives the forceps lifting sleeve 41 to drive the rotating disc 44 to rotate around the axis of the rotating disc 44, thereby realizing the swing of the end of the endoscope.

[0112] It should be noted that the posture driving motor 32 has an output button 322 and a retraction button 323. The push rod 321 can be manually operated to be pushed out and retracted through the output button 322 and the retraction button 323, thereby realizing the swing of the end of the endoscope.

[0116] It should be noted that the control of the cantilever 2 can be realized by operating the button shell 366, and the button shell 366 is arranged on the first handle 361 and the second handle 362 respectively, so as to prevent misoperation, and only when the two button shells 366 are pressed at the same time, the cantilever 2 can be adjusted to a rotatable state, and the adjustment of the cantilever 2 is realized.

[0118] The top of the rotating shaft 21 is rotatably engaged with one end of the first connecting rod 201 connected thereto via a bearing 26, forming a first joint 232. A joint expansion sleeve 2321 is provided on the first joint 232, which rotatably engages with the top of the rotating shaft 21, serving as a limiting and damping mechanism. The other end of the first connecting rod 201 rotatably engages with one end of the second connecting rod 202, forming a second joint 2011. The other end of the second connecting rod 202 rotatably engages with one end of the third connecting rod 203, forming a third joint 2021. The other end of the third connecting rod 203 rotatably engages with a fourth connecting rod 202... The rod 204 rotates to form the fourth joint 2031.

The rotating shaft 21 is provided with a positioning pin 211. The positioning pin 211 cooperates with the rotating positioning block 231 located inside the second fixed seat 23 to ensure that the positioning pin 211 is restricted by the rotating positioning block 231 when the rotating shaft 21 rotates, so that the rotating shaft 21 can only rotate within a set angle when it is rotatable, and cannot achieve 360° rotation.

[0119] The working principle of this invention is as follows:

[0120] During surgery, medical staff push the base 1 to the vicinity of the bed and patient, brake the casters 12, and then manually press the two button housings 366 to adjust the position of the cantilever 2 and the U-shaped support 35. After adjustment, release the button housings 366 to fix the support 35 in a suitable position for surgery, so that subsequent intubation and surgery can be performed.

[0121] When X-ray irradiation is required, doctors can remotely control the movements of the first motor, the second motor, and the posture drive motor 32 via a smart terminal to meet the needs of remote surgery, thereby reducing radiation and protecting the health of medical staff.
