[0026] See also Figure 1 to Figure 5In an embodiment of the present invention, an automatic locking mechanism device for a surgical retractor includes a support frame 1, an arc-shaped support plate 11 is fixedly connected to the support frame 1, a locking hook plate 2 is arranged on the outer side of the arc-shaped support plate 11, and a locking hook 22 is arranged on the locking hook plate 2, characterized in that a locking connection component 3 is arranged on the locking hook plate 2, and the locking connection component 3 includes a bottom driving seat 31, an insertion locking frame 32, a telescopic locking rod 33, a rotation control member 34 and a downward pressing locking member 35, the bottom driving seat 31 is located at the bottom of the arc-shaped support plate 11, and the rotation control member 34 is hinged with the insertion locking frame 32. When the locking hook 22 is located at the wound, the surface of the wound is relaxed. The skin position is set, the rotation control piece 34 rotates counterclockwise, and when the inserted locking frame 32 is located at the wound to tighten the epidermis, the rotation control piece 34 rotates clockwise, the locking hook 22 is in a fixed position, and the pressing locking piece 35 is tightly attached to the outer end surface of the locking hook plate 2. A locking detection component 4 is provided on the outer side of the arc-shaped support plate 11, and the locking detection component 4 includes an arc-compliant plate 41, a loading center disk 42 and a hook straight rod 43. A contact friction head 431 is fixedly connected to the top of the hook straight rod 43, and the contact friction head 431 contacts the bottom of the locking hook plate 2, so that the position of the locking hook plate 2 is changed while changing the position of the hook straight rod 43.

[0027] In this embodiment, when in use, the support frame 1 can be located outside the bed to play a role in fixing the position. The locking hook plate 2 is provided with a plurality of locking grooves 21. The rotating control member 34 is located in the locking groove 21. One side of the rotating control member 34 abuts against the inner wall of the locking groove 21. The locking groove 21 suitable for the position is selected for use. The locking hook 22 of the locking hook plate 2 is facing the wound position. The surgeon determines the position of the locking hook plate 2 by selecting a suitable position, inserts the locking frame 32 into the locking groove 21, and retracts the locking rod 33. Start to press the locking member 35 down to the locking position, the telescopic locking rod 33 can be electric, the contact friction head 431 is in contact with the locking hook plate 2 in advance, the hook straight rod 43 is in a vertical state, and the hook straight rod 43 is slid to the bottom position of the locking hook plate 2 along the following guide cavity 411 of the arc plate 41, and the bottom of the pressing locking member 35 has a rotatable disk, the pressing locking member 35 is perpendicular to the locking hook plate 2, and the locking hook plate 2 is locked, and the pressing locking member 35 is horizontal with the locking hook plate 2 to disengage from the locking hook plate 2. When inserted, the pressing locking member 35 is in a horizontal state, and the pressing locking member 35 is in a vertical state, so that the pressing locking member 35 is located at the top of the locking hook plate 2.

[0028] During the operation, according to the environmental conditions in the wound, the position of the rotating control member 34 can be rotated to relax the epidermal position or tighten the epidermal position of the locking hook 22. Both sides of the bottom of the pressing locking member 35 are fixedly connected with holding resistance members 36 for increasing the contact resistance with the locking hook plate 2. The rotating control member 34 is driven by a motor to rotate. The motor can drive the rotating control member 34 to move. The motor can be connected to the bottom driving seat 31. Before moving, the pressing locking member 35 needs to be moved upward. Each time through the setting, only about half a centimeter of movement is required. The material of the holding resistance member 36 can be rubber. While providing resistance, the holding resistance member 36 can be squeezed by pressing the locking member 35, thereby moving the position of the rotating control member 34 and rotating the rotating control member 34 counterclockwise. At this time, one end of the locking hook 22 is slightly tilted. When the locking hook 22 is in the raised state, the locking hook 22 can be located at the relaxed epidermis position at the wound, so that the position of the wound can be easily checked to avoid affecting the operation in the tight state. When the rotating control member 34 is rotated clockwise, one end of the locking hook 22 is in a slightly downward state, and the locking frame 32 can be inserted to locate the tight epidermis position at the wound, which can be beneficial for cleaning the position of the wound. After that, the original state is restored, and the influence of the contact between the hook and the contact epidermis position is controlled, which is convenient for cleaning the internal wound and reducing the possibility of re-operation. A convex adjustment member 5 corresponding to the locking hook plate 2 is fixedly connected to the top of the arc-shaped support plate 11. The function of the convex adjustment member 5 is that when the rotating control member 34 drives the locking hook plate 2 to move, it can move with this position as the center of the circle, so as to control the position of the locking hook plate 2.

[0029] When the rotating control member 34 moves, the locking hook plate 2 resists the movement of the hook straight rod 43, and the direction of movement is detected and displayed in time to ensure that the locking hook plate 2 is used in the correct direction. The locking hook plate 2 contacts the position of the contact friction head 431. When driving the hook straight rod 43 to move, an inner concave cavity detection area 44 for detecting the position change of the hook straight rod 43 is provided in the loading center disk 42. A plurality of distance sensors are installed in the inner concave cavity detection area 44. The distance is detected by multiple distance sensors. The closer the distance, the closer the hook straight rod 43 moves toward the direction, and the farther the hook straight rod 43 moves away from the position. This is conducive to timely detection according to the movement of the locking hook plate 2, and an alarm can be set. If an erroneous operating state occurs, it can be corrected in time. The movement structures of the locking hook plate 2, the rotating control member 34, and the pressing locking member 35 are all slow to ensure safety during use.

[0030] like Figure 1 to Figure 5 The present invention also provides a method for using an automatic locking mechanism device for a surgical retractor, and the specific steps are as follows:

[0031] A: The locking hook 22 of the locking hook plate 2 is facing the wound position. The surgeon determines the position of the locking hook plate 2 by selecting a suitable position, inserts the locking frame 32 into the locking slot 21, activates the telescopic locking rod 33 to press the locking member 35 downward to the locking position, and slides the hook straight rod 43 along the following guide cavity 411 to the bottom position of the locking hook plate 2;

[0032] B: During the operation, the position of the rotating control member 34 can be rotated according to the environmental conditions in the wound to relax the epidermis or tighten the epidermis of the locking hook 22. When the rotating control member 34 moves, the locking hook plate 2 resists the movement of the hook straight rod 43, and the direction of the movement is detected and displayed in time to ensure that the locking hook plate 2 is used in the correct position.

[0033] The working principle of the present invention is as follows: when in use, the supporting frame 1 can be located outside the hospital bed to play the role of fixing the position, and the locking hook 22 of the locking hook plate 2 is facing the wound position. The surgeon determines the position of the locking hook plate 2 by selecting a suitable position, and inserts the locking frame 32 into the locking groove 21, and starts the downward locking member 35 by telescopic locking rod 33 to press down the locking position. The telescopic locking rod 33 can be electric, and the hook straight rod 43 slides along the following guide cavity 411 of the arc plate 41 to the bottom position of the locking hook plate 2. During the progress of the operation, according to the environmental conditions in the wound, the position of the rotating control member 34 can be rotated to relax the epidermis position or tighten the epidermis position of the locking hook 22, and both sides of the bottom of the downward locking member 35 are fixedly connected to be useful In order to increase the contact resistance with the locking hook plate 2, the holding resistance member 36 is used to increase the contact resistance with the locking hook plate 2. The rotation control member 34 is driven by a motor to rotate. The motor can drive the rotation control member 34 to move. The motor can be connected to the bottom driving seat 31. Before the movement, the pressing locking member 35 needs to be moved upward. Each time through the setting, only about half a centimeter is required to be moved. The material of the holding resistance member 36 can be rubber. While providing resistance, the holding resistance member 36 can be squeezed by pressing the locking member 35, so that the position of the rotation control member 34 can be moved. The rotation control member 34 is rotated counterclockwise. At this time, one end of the locking hook 22 is in a slightly raised state, and the locking hook 22 can be located at a relaxed epidermal position at the wound. At this time, the position of the wound can be easily checked to avoid being in a tight state. The locking hook plate 2 is moved in a direction that is centered on the locking hook plate 2, and the locking hook plate 2 is moved in a direction that is centered on the locking hook plate 2, so that the locking hook plate 2 can be moved in a direction that is centered on the locking hook plate 2. The measured movement direction is displayed in time to ensure that the locking hook plate 2 is used in the correct direction. The locking hook plate 2 contacts the position of the contact friction head 431. When driving the hook straight rod 43 to move, the loading center plate 42 is provided with an inner concave cavity detection area 44 for detecting the position change of the hook straight rod 43. A number of distance sensors are installed in the inner concave cavity detection area 44. The distance is detected by multiple distance sensors. The closer the distance is, the movement of the hook straight rod 43 is towards this direction, and the farther the distance is, the movement of the hook straight rod 43 is away from this position. This is conducive to timely detection according to the movement of the locking hook plate 2, and an alarm can be set. If an erroneous operating state occurs, it can be corrected in time. The movement structures of the locking hook plate 2, the rotating control member 34, and the pressing locking member 35 are all slow.Ensure safety during use.
