[0043] The connector 100 comprises the collet 110, the locking sleeve 120 and the abutting member 130, the collet 110 has a mounting chamber 111 for mounting the surgical instrument 200, a through hole 112 is provided through the side wall of the collet 110 and communicates with the mounting chamber 111; the locking sleeve 120 is movably sleeved on the collet 110 and can be switched between a first position and a second position; the abutting member 130 is movably arranged in the through hole 112 and is used for being actuated by the locking sleeve 120 and moving towards the mounting chamber 111 when the locking sleeve 120 moves to the first position, so as to lock the surgical instrument 200; and for being released by the locking sleeve 120 when the surgical locking sleeve 120 moves to the second position, so as to be able to unlock the surgical instrument 200.

[0044] Specifically, when the locking sleeve 120 is located at the first position, the locking sleeve 120 abuts against the abutting member 130, so that the abutting member 130 moves along the axis direction of the through hole 112 towards the mounting chamber 111, and then the abutting member 130 abuts against the surgical instrument 200 extending out of the collet 110, at this time, the connector 100 is in a locked state; when the locking sleeve 120 is located at the second position, the locking sleeve 120 has a gap with the abutting member 130, so that the abutting member 130 has a displacement space moving along the axis direction of the through hole 112 towards the gap, at this time, the connector 100 is in an unlocked state.

[0045] It should be noted that, please refer to Figure 6 and Figure 7 , the surgical instrument 200 is provided with a groove 210 for abutting against the abutting member 130 to lock the surgical instrument 200. In the process of extending the surgical instrument 200 into the collet 110, the groove 210 gradually approaches the abutting member 130, so that the abutting member 130 can move along the axis direction of the through hole 112 towards the groove 210, and then abut against the groove 210.

[0046] It can be understood that the abutting member 130 in the embodiment is a ball; in other embodiments, the abutting member 130 can also be a cylindrical structure, and the utility model does not limit the structure of the abutting member 130.

[0047] The working principle of the connector 100 in the surgical device 300 provided by the utility model is as follows:

[0048] When the connector 100 is in the initial state, the locking sleeve 120 is located at the first position, at this time, the locking sleeve 120 abuts against the abutting member 130, so that the abutting member 130 moves along the axis direction of the through hole 112 towards the mounting chamber 111, that is, the initial state of the connector 100 is a locked state.

[0049] When it is needed to install the surgical instrument 200 with the connector 100, the locking sleeve 120 is slid so that the locking sleeve 120 moves to the second position, at this time, the abutting piece 130 has a gap with the locking sleeve 120, so that the abutting piece 130 has a displacement space moving along the axis direction of the through hole 112 towards the locking sleeve 120, thereby converting the locking state of the connector 100 to the unlocking state. The surgical instrument 200 is inserted into the connector 100, and the abutting piece 130 is pushed to move along the axis direction of the through hole 112 towards the locking sleeve 120, so that the groove 210 gradually approaches the abutting piece 130, thereby making the abutting piece 130 move along the axis direction of the through hole 112 towards the groove 210, causing part of the abutting piece 130 to fall into the groove 210 and abut with the groove 210. Then, the locking sleeve 120 is slid again so that the locking sleeve 120 moves to the first position, thereby abutting with the abutting piece 130, so that the surgical instrument 200 is again in the locking state, thereby completing the installation of the surgical instrument 200 with the connector 100.

[0050] Conversely, when it is needed to disassemble and take out the surgical instrument 200, the locking sleeve is slid so that the locking sleeve 120 moves to the second position, so that the connector 100 is in the unlocking state, thereby making the abutting piece 130 have a displacement space moving along the axis direction of the through hole 112 towards the locking sleeve 120, and the surgical instrument 200 is taken out outward, the groove 210 gradually moves away from the abutting piece 130, so that the abutting piece 130 moves along the axis direction of the through hole 112 towards the locking sleeve 120, thereby taking out the surgical instrument 200.

[0051] Therefore, the connector 100 is movably connected with the abutting piece 130 through the through hole 112 penetratingly arranged on the side wall of the collet 110, and the locking sleeve 120 movably arranged on the collet 110, so that when the locking sleeve 120 is in the first position, the abutting piece 130 is moved towards the installation chamber 111, thereby locking the surgical instrument 200; when the locking sleeve 120 is in the second position, the abutting piece 130 is released, thereby unlocking the surgical instrument 200, thereby realizing the quick installation or disassembly between the connector 100 and the surgical instrument 200, and improving the plugging efficiency.

Specifically, the elastic member 140 is stretched and contracted along the axis direction of the locking sleeve 120, thereby driving the locking sleeve 120 to slide relative to the collet 110 by using the restoring force of the elastic member 140, thereby saving manpower and improving the plugging efficiency.

[0053] According to the above arrangement, please refer to Figure 4 and Figure 5 In the present embodiment, the locking sleeve 120 is provided with a boss 121 on the inner wall in the circumferential direction, which is used to actuate the abutting member 130 and move it towards the mounting chamber 111 when it moves to the first position, so as to lock the surgical instrument 200; and is used to release the abutting member 130 when it moves to the second position, so as to be able to unlock the surgical instrument 200. Specifically, when the boss 121 is in the first position, the boss 121 abuts against the abutting member 130, at which time the connector 100 is in the locked state; when the boss 121 is in the second position, the boss 121 is separated from the abutting member 130, at which time the connector 100 is in the unlocked state; so as to switch the state of the connector 100 by switching the position of the boss 121. In the present embodiment, the elastic member 140 abuts against the boss 121, so as to be able to drive the position of the boss 121 to change by the restoring force of the elastic member 140.

[0054] In the present embodiment, the boss 121 is arranged in a ring shape along the peripheral surface of the locking sleeve 120, so as to abut against one or more abutting members 130 by one ring-shaped boss 121. In other embodiments, the boss 121 is arranged in an arc shape along the peripheral surface of the locking sleeve 120, and each arc-shaped boss 121 can be used to abut against one or more abutting members 130.
