It should be added that, as shown in fig. 9, a spray head 700 is disposed in the housing 100 and above the fixing rod 220 by a preset distance, and the spray hole of the spray head 700 faces downward, so as to spray a cleaning agent (liquid) to clean the forceps 900.
It is also added that the casing 100 is provided with a taking and placing opening 110, the taking and placing opening 110 is fan-shaped, and a worker can install the forceps 900 on the fixing frame 260 or remove the forceps 900 from the fixing frame 260 through the taking and placing opening 110.

It should be further noted that, to drive the sliding rod 250 to reciprocate along the fixed rod 220, a hydraulic telescopic rod may be disposed on the fixed rod 220, such that a fixed end of the hydraulic telescopic rod is connected to the fixed rod 220, and a telescopic end of the hydraulic telescopic rod is fixedly connected to the sliding rod 250, so that the sliding rod 250 is driven to reciprocate along an axis of the fixed rod 220 by telescopic movement of the hydraulic telescopic rod.
It should be further added that, as shown in fig. 3 and fig. 5, in order to drive the central shaft 210 to rotate, specifically, a driven ring 810 is fixedly connected to the outer periphery of the central shaft 210, a motor 830 is fixedly disposed on the housing 100, an output end of the motor 830 is connected to a driving ring 820, and the driving ring 820 is meshed with the driven ring 810, so that torque is output outwards through the motor 830 to drive the central shaft 210 to rotate around the first axis. In other embodiments, driven ring 810 may also be replaced with a driven gear and driving ring 820 may be replaced with a driving gear.
It will be appreciated that the present application is capable of cleaning not only surgical forceps 900, but also medical instruments having articulating structures such as forceps and scissors.
In a further embodiment, as shown in fig. 3, a guide assembly 300 is disposed between the sliding rod 250 and the housing 100, and the guide assembly 300 is used to replace a hydraulic telescopic rod, so that in this embodiment, the sliding rod 250 can be driven to reciprocate along the axial direction of the fixed rod 220 by the guide assembly 300 without providing a hydraulic telescopic rod on the fixed rod 220, so that the included angle between two edges of the forceps 900 is reciprocally changed between the maximum and minimum two-edge closure.
In a further embodiment, as shown in fig. 2, 3 and 8, the guide assembly 300 includes a ball head 310 and a relief ring 320, the ball head 310 is fixedly connected to an end of the sliding rod 250 away from the fixed rod 220, the relief ring 320 is connected in the housing 100 and concentric with the central shaft 210, an inner circumferential surface of the relief ring 320 is divided into a convex portion and a concave portion, the convex portion and the concave portion are alternately connected, the ball head 310 is magnetically connected to the inner circumferential surface of the relief ring 320, and specifically, any one of the ball head 310 and the relief ring 320 may be made of a magnetic material, and the other one may be made of an iron-cobalt-nickel material.
In the process that the ball head 310, the sliding rod 250 and the fixing rod 220 rotate along the central shaft 210, when the ball head 310 rotates from the concave part to the convex part of the undulating ring 320, the ball head 310 moves towards the direction close to the axis of the central shaft 210 under the guiding action of the convex part of the undulating ring 320, so that the included angle value between the two elastic telescopic rods 240 is increased, the distance between the two fixing frames 260 is further increased, the included angle value between the two edges of the surgical forceps 900 is further increased, the surgical forceps 900 are unfolded to the maximum opening angle, and as the ball head 310 continuously rotates synchronously with the central shaft 210, when the ball head 310 rotates from the convex part to the concave part of the undulating ring 320, the ball head 310 starts to move towards the direction far away from the axis of the central shaft 210 under the guiding action of the concave part of the undulating ring 320, so that the included angle value between the two elastic telescopic rods 240 is reduced, and the distance between the two fixing frames 260 is further reduced, the included angle value between the two edges of the surgical forceps 900 is further reduced, and the surgical forceps 900 is closed to the maximum closing angle; in summary, through the continuous rotation of the central shaft 210, the telescopic end of the elastic telescopic rod 240 can drive the sliding rod 250 to reciprocate along the axis of the fixed rod 220, so that the angle between the two edges of the forceps 900 is reciprocally switched between the maximum value and the minimum value when the two edges are closed.
It should be further added that the relief ring 320 is further provided with a corresponding opening 321 adapted to the shape of the access opening 110.
It should be further added that a draining plate 120 is also provided at the lower end of the pick-and-place port 110.
In a further embodiment, as shown in fig. 2, 6 and 8, the undulating ring 320 is elastically coupled within the housing 100 and the undulating ring 320 is capable of sliding in a vertical direction, specifically, an elastic guide post 330 is provided between the bottom of the undulating ring 320 and the bottom of the housing 100, and the inner circumferential area of the undulating ring 320 gradually decreases from top to bottom in the vertical direction, specifically, the interval between the convex portion and the concave portion of the undulating ring 320 and the axis of the central shaft 210 gradually decreases from top to bottom in the vertical direction.
Because the maximum angles at which each forceps 900 can be opened are not exactly the same, the maximum angles at which each forceps 900 can be opened are approximately ninety degrees, and the maximum angles at which each forceps 900 can be opened are approximately thirty degrees, in order to ensure that the stress of the hinge points of different forceps 900 is basically consistent when the forceps 900 are opened to the maximum angles, the deformation caused by the damage of the forceps 900 due to the overlarge stress is avoided, and the vertical position of the undulating ring 320 is required to be adjusted, so that when the maximum angles at which the forceps 900 can be opened are large, the distance between the convex part and the concave part of the undulating ring 320 and the axis of the central shaft 210 is small, and when the maximum angles at which the forceps 900 can be opened are small, the distance between the convex part and the concave part of the undulating ring 320 and the axis of the central shaft 210 is large, so that the difference of the elastic force of the pressure springs in the elastic telescopic rods 240 is not too great, and the stress of the hinge points of the forceps 900 is basically consistent.
It will be appreciated that after the forceps 900 is opened to the maximum opening angle, if the sliding rod 250 continues to move toward the axial direction of the central shaft 210 at this time, the compression spring in the elastic telescopic rod 240 will be compressed, the elastic force generated by the compression of the spring will push the two handle rings of the forceps 900, and if the elastic force of the spring is too large, the hinge point of the forceps 900 will be stressed too much to damage and deform.
In the initial state, the inner circumferential surface of the undulating ring 320 is not pressed by the ball head 310, the undulating ring 320 is at the highest position which can move in the vertical direction, if the maximum angle value of the surgical forceps 900 which is arranged on the fixing frame 260 at this time is small, the spacing between the convex part and the concave part of the undulating ring 320 which are in contact with the ball head 310 and the axis of the central shaft 210 becomes larger after the surgical forceps 900 are opened to the maximum angle value, and then the spacing between the convex part and the concave part of the undulating ring 320 which are pushed by the sliding rod 250 along the axis direction of the fixed rod 220 is reduced as the sliding rod 250 continues to move towards the axis direction which is close to the central shaft 210, so that the contact pressure of the ball head 310 which is connected with the elastic telescoping rod 240 and the inner circumferential surface of the undulating ring 320 is increased, and the inner circumferential surface of the undulating ring 320 is an inclined surface, so that the ball head 310 can apply lower pressure to the undulating ring 320 through the inclined surface, and the elastic force of the elastic part in the undulating ring 320 overcomes the elastic guide post 330 can vertically move downwards, so that the spacing between the convex part and the concave part of the undulating ring 320 which is in contact with the ball head 310 and the axis 210 is larger than the axis of the central shaft 210 is smaller, and the spacing between the convex part and the concave part of the convex part of the sliding ring and the concave part of the sliding ring 250 which is smaller than the axis of the central shaft 210 is smaller than the axial direction, so that the maximum angle of the elastic forceps 900 is not damaged by the maximum angle value of the elastic forceps 900 and the pressure of the surgical forceps is substantially and the largest.
It should be further added that, in order to make the ball head 310 able to follow the rotation of the sliding rod 250 around the first axis, the height of the undulating ring 320 does not change all the time, and the number of the protruding portions and the number of the concave portions of the undulating ring 320 are adapted to the number of the ball heads 310, so that the sum of the elastic forces of the compression springs in all the elastic telescopic rods 240 is unchanged, and at this time, the sum of the elastic forces of the compression springs in all the elastic telescopic rods 240 and the sum of the elastic forces of the compression springs in all the elastic guide posts 330 are a pair of balance forces, so that the height of the undulating ring 320 is automatically adjusted to a suitable height position and does not change any more.
It will be appreciated that if the height of the undulating ring 320 is not adjusted, after the operating forceps 900 are expanded to the maximum angle value, the operating forceps 900 will maintain the maximum angle value for a certain period of time as the central shaft 210 continues to rotate, and the angle value of the operating forceps 900 is not dynamically changed during this period of time, so that the cleaning time corresponding to the different angle values of the operating forceps 900 being expanded is not the same, the cleaning time corresponding to the maximum angle value of the operating forceps 900 being expanded, and the cleaning time corresponding to the other angle values being expanded to the operating forceps 900 being short, so that it is not ensured that the uniform cleaning of the intersecting shielding area of the operating forceps 900 is performed, and therefore the height of the undulating ring 320 needs to be adjusted to a suitable position, and the angle value of the operating forceps 900 is always dynamically changed during the rotation of the operating forceps 900 following the central shaft 210, and the problem that the operating forceps 900 remains unchanged after being expanded to the maximum angle value is avoided.
In a further embodiment, as shown in fig. 3 and 4, a transmission assembly 400 is provided between the fixing rod 220 and the central shaft 210, the transmission assembly 400 being used to drive the fixing rod 220 to rotate about its own axis when the central shaft 210 rotates about the first axis; in the process that the fixing rod 220 rotates around the axis of the fixing rod 220, the fixing rod 220 drives the sliding rod 250 to synchronously rotate, the sliding rod 250 drives the elastic telescopic rod 240 to synchronously rotate through the hinge post 270, and the elastic telescopic rod 240 drives the surgical forceps 900 to synchronously rotate through the fixing frame 260, so that two sides of the surgical forceps 900 can be washed by the cleaning agent sprayed by the spray head 700, and the whole of the surgical forceps 900 can be sufficiently cleaned.
