Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.
The endoscope adapter is provided in the embodiment to solve the technical problems that in the prior art, when an endoscope is to be inserted in an operation, an operator needs to observe and judge the circumferential position where the output end of the adapter is matched with the endoscope, the endoscope can be inserted in an aligned mode, and in the process that the endoscope is inserted into the adapter, the output end of the adapter can still rotate, so that the endoscope cannot be loaded in place at one time, and poor use experience is brought to a user.
As shown in fig. 1, in the preparation process before an operation, the endoscope adapter provided in this embodiment is drivingly connected to the endoscope 100 and the sterile adapter 200, and in the preparation process before the operation, the sterile adapter 200 is first mounted on a robot arm, and then the endoscope adapter with the endoscope 100 mounted thereon is mounted on the sterile adapter 200, and a mechanical transmission relationship is established between the three, so that the endoscope 100 is driven by the sterile adapter 200 to rotate along its own axis.
Specifically, as shown in fig. 2 and 3, the endoscope adapter provided by the present embodiment includes a transmission unit 1, a lock limit mechanism 2, and a first lock unit 3, and the sterile adapter 200 can drive the endoscope 100 to rotate along its axis through the transmission unit 1. The locking limiting mechanism 2 is used for locking the transmission unit 1 or limiting the endoscope 100 to move along the axial direction, when the endoscope 100 is not installed, the locking limiting mechanism 2 locks the transmission unit 1, and therefore the phenomenon that the transmission unit 1 changes relative to the zero position when leaving a factory due to human/non-human reasons, and the endoscope 100 cannot be installed in place at one time in the later period is avoided. When the endoscope 100 is installed, the first locking unit 3 can drive the locking and limiting mechanism 2 to move so as to install the endoscope 100 and unlock the transmission unit 1, installation of the endoscope 100 is achieved, but meanwhile, the transmission unit 1 is also unlocked by movement of the locking and limiting mechanism 2, and in order to avoid displacement of the transmission unit 1 when the endoscope 100 is installed and ensure that the endoscope 100 is installed in place at one time, the first locking unit 3 locks the transmission unit 1. After the endoscope 100 is installed, the first locking unit 3 can unlock the transmission unit 1 and drive the locking and limiting mechanism 2 to reset so as to limit the endoscope 100 to move along the axial direction and unlock the transmission unit 1, the locking and limiting mechanism 2 and the first locking unit 3 both unlock the transmission unit 1 so as to ensure that the endoscope 100 can rotate around the axis of the endoscope 100 along with the transmission unit 1, and the locking and limiting mechanism 2 limits the endoscope 100 to move along the axial direction of the endoscope 100 so as to prevent the endoscope 100 from being separated from the endoscope adapter in the rotation process.
The endoscope adapter provided by the embodiment improves the probability that the endoscope 100 is successfully installed at the expected position at one time, is simple to operate, and greatly improves the user experience.
In this embodiment, the endoscope adapter further comprises a housing 5 to provide a mounting carrier for the mounting of the transmission unit 1, the locking stop mechanism 2 and the first locking unit 3.
As shown in fig. 4, the transmission unit 1 includes a gear transmission set 11, a driving gear 111 of the gear transmission set 11 is detachably and drivingly connected with the sterile adaptor 200, an output gear 112 of the gear transmission set 11 is coaxially connected with a sleeve 113, and the endoscope 100 is inserted into the sleeve 113. The sterile adapter 200 provides a driving force on the drive gear 111, which is transmitted to the output gear 112 to drive the endoscope 100 to rotate. The gear transmission structure has good transmission stability, simple structure and convenient material taking, and reduces the production cost. In other embodiments, the transmission unit 1 may also be a wire transmission mechanism, such as a wire rope transmission mechanism, a sprocket chain transmission mechanism, a synchronous belt transmission mechanism, etc.
Further, the gear transmission set 11 provided by the present embodiment includes a driving gear 111, an intermediate idle gear 115 engaged with the driving gear 111, and an output gear 112 engaged with the intermediate idle gear 115.
In order to facilitate the installation of the endoscope 100 and improve the installation efficiency of the endoscope 100, as shown in fig. 5, a first circumferential positioning member 114 is disposed on the inner wall of the sleeve 113, and the first circumferential positioning member 114 is connected to the second circumferential positioning member 101 of the endoscope 100. The first circumferential positioning element 114 and the second circumferential positioning element 101 are coupled to each other, so that the endoscope 100 can rotate synchronously with the sleeve 113, and the problem that the endoscope 100 does not rotate or rotates asynchronously with the sleeve 113 is avoided. Specifically, the first circumferential positioning element 114 is a protruding block protruding from the inner wall of the sleeve 113, the protruding block extends along the inner wall of the sleeve 113 in the circumferential direction, a plurality of notches are formed in the protruding block at intervals, the second circumferential positioning element 101 is a plurality of clamping blocks circumferentially arranged along the outer side wall of the endoscope 100 at intervals, and the clamping blocks are clamped in the notches to realize the positioning and installation of the endoscope 100.

The second locking unit 22 is connected with the clamping unit 21, and when the endoscope 100 is not installed, the second locking unit 22 locks the transmission unit 1, so that the situation that the transmission unit 1 is changed relative to the zero position when the endoscope 100 leaves the factory due to human/non-human reasons, and the endoscope 100 cannot be installed in place at one time in the later period is avoided. When the endoscope 100 is mounted, the second locking unit 22 unlocks the transmission unit 1, ensuring that the endoscope 100 can rotate about its axis with the transmission unit 1.

A first elastic member 223 is connected to the locking block 221, and the first elastic member 223 connects the first locking member 222 to the transmission unit 1 or allows the grip unit 21 to restrict the endoscope 100 from moving axially. The first locking unit 3 can drive the locking block 221 to move so that the first locking member 222 is far away from the transmission unit 1 and simultaneously the clamping unit 21 is displaced so as to mount the endoscope 100, the first elastic member 223 is compressed, and the first elastic member 223 enables the first locking member 222 to always have a tendency to lock the transmission unit 1 and enables the clamping unit 21 to always have a tendency to clamp the endoscope 100. In order to make the driving unit 1 work normally after the endoscope 100 is mounted, the clamping unit 21 will unlock the driving unit 1 by the first locking unit 3 after clamping the endoscope 100, i.e. the first locking member 222 is not connected to the driving unit 1.
As shown in fig. 10, the second locking unit 22 locks the output end of the transmission unit 1, and since the transmission unit 1 includes the gear transmission set 11, it is preferable that the second locking unit 22 locks the output gear 112 of the gear transmission set 11, that is, the first locking member 222 is connected to the output gear 112 in a matching manner, and then the first locking member 222 includes locking teeth engaged with the output gear 112, and the locking teeth are disposed on the locking block 221. The structure of the first locking member 222 is set according to the structure of the transmission unit 1, and is not particularly limited herein.

The opening 212 is preferably arcuate in shape to conform to the shape of the outer perimeter of the endoscope 100 without interfering with the rotation of the endoscope 100. According to the structure of the second locking unit 22, preferably, each of the grippers 211 is connected with one second locking unit 22, specifically, the grippers 211 are connected with the locking blocks 221, and the first locking unit 3 can drive the two locking blocks 221 to move, so as to drive the two grippers 211 to move.
Further, in order to improve the stability of the clamping unit 21 in clamping the endoscope 100, in the present embodiment, a boss is provided on the outer wall of the endoscope 100 along the circumferential direction, the boss is disposed below the lowermost clamp 211, and when the clamping unit 21 clamps the endoscope 100, the endoscope 100 is prevented from moving axially and disengaging from the endoscope adapter.
The first locking unit 3 can drive the locking stop mechanism 2 to mount the endoscope 100 and unlock the transmission unit 1, and in the present embodiment, as shown in fig. 12 and 13, the first locking unit 3 includes an endoscope release button 31, a push rod 33, and a second elastic member 35.
