[0056] Referring to Figure 5 In the sterile cover interface 100 described above, one end of the base 110 is connected to the side of the mechanical arm 212, and a clamping groove 111 is formed on the side of the base 110 away from the mechanical arm 212. One end of the clamping member 130 is provided with a protruding ring 133 which is pluggable along the axial direction of the protruding ring and is arranged in the clamping groove 111. The resilient member 120 is connected to the base, and a clamping member 121 is connected. The clamping member 121 is close to the clamping member 130 along the radial direction of the protruding ring 133 under the elastic force of the resilient member 120.

[0057] In the assembly process of the sterile cover interface 100 described above, first, one end of the base 110 is connected to the side of the mechanical arm 212, then the resilient member 120 is sleeved on the outer periphery of the base 110, the clamping member 121 is arranged in the strip-shaped through hole 112 and partially located in the clamping groove 111, and one end of the clamping member 130 away from the base 110 is connected to the side wall of the cylindrical cover body 211, such as Figure 1The operator holds the clamping member 130 and sets the cylindrical cover 211 from the end of the mechanical arm 212 close to the patient to the outer periphery of the mechanical arm 212, as shown in Figure 1 Then the convex ring 133 is inserted into the clamping groove 111, as shown in Figure 4 The convex ring 133 rubs against the clamping members 121, so that the elastic member 120 is deformed radially along the convex ring 133, and the convex ring 133 passes through the clamping members 121 and enters the clamping groove 111, at this time, the clamping member 130 is in the first state, as shown in Figure 2 and 5 The convex ring 133 is located between the bottom wall of the clamping groove 111 and the clamping members 121. After the operation is completed, the operator holds the clamping member 130 from the outside of the cylindrical cover 211 and drives the convex ring 133 away from the clamping groove 111, the convex ring 133 rubs against the clamping members 121, so that the elastic member 120 is deformed radially along the convex ring 133, and the convex ring 133 passes through the clamping members 121 and leaves the clamping groove 111, at this time, the clamping member 130 is in the second state, as shown in Figure 3 The convex ring 133 leaves the base 110, and finally the operator holds the clamping member 130 and removes the cylindrical cover 211 from the end of the mechanical arm 212 close to the patient, at this time, the mechanical arm 212 is exposed and not wrapped by the cylindrical cover 211. The sterile cover interface 100 cooperates with the clamping member 130, the elastic member 120 and the clamping groove 111 of the base 110 to achieve the setting of the cylindrical cover 211 on the outer periphery of the mechanical arm 212 and the fixation. After the operation is completed, the clamping member 130 is held and separated from the base 110, the elastic member 120 is deformed, and finally the clamping member 130 is separated from the base 110, so that the cylindrical cover 211 is removed from the mechanical arm 212, without the need for magnetic maintenance of the metal. The mechanical structure of the clamping member 130 is stable, and the sterile cover is not contaminated or affected by the operation. In addition, the material of the sterile cover interface 100 can be set as a degradable elastic plastic material, so as to facilitate recycling.

[0058] Referring to Figure 5 and Figure 6 In an embodiment, the clamping member 130 includes a clamping card 131 and a clamping ring 132, the clamping ring 132 is attached to one side of the clamping card 131, and the clamping ring 132 is located in the cylindrical cover 211. The outer periphery of the end of the clamping ring 132 away from the clamping card 131 has a convex ring 133, so that the operator can hold the clamping card 131 and insert the clamping ring 132 into the clamping groove 130, and when the clamping member 130 is in the first state, the convex ring 133 is located between the clamping members 121 and the bottom wall of the clamping groove, and the clamping members are located between the convex ring and the clamping card, so that the clamping of the clamping member and the base is more stable.

[0059] Referring to Figure 7 andFigure 10 In an embodiment, the inner side wall of the clamping groove 111 is provided with a plurality of strip-shaped through holes 112 extending in the circumferential direction. The inner side of the elastic member 120 is connected with a plurality of inwardly protruding clamping members 121. The elastic member 120 is sleeved on the outer periphery of the base 110. The plurality of clamping members 121 correspond to the plurality of strip-shaped through holes 112 one by one. The clamping members 121 are arranged in the strip-shaped through holes 112 and partially located in the clamping groove 111, so that the cooperation between the elastic member and the base is more compact, and the entire sterile cover interface 100 is smaller in size.

[0060] Referring to Figure 6 Specifically, the acute angle formed by the arc-shaped section of the side of the convex ring 133 away from the card 131 and the axis of the clamping ring 132 is a first angle, and the acute angle formed by the arc-shaped section of the side of the convex ring 133 close to the card 131 and the axis of the clamping ring 132 is a second angle. The first angle is smaller than the second angle.

[0061] Referring to Figures 2-5 In an embodiment, the sterile cover interface 100 further comprises an annular protruding portion 140. The inner periphery of the annular protruding portion 140 is connected with the outer side wall of the base 110. When the elastic member 120 is sleeved, the elastic member 120 is first expanded, then the elastic member 120 is sleeved on the side of the annular protruding portion 140 away from the card 131, then the clamping members 121 are corresponded with the strip-shaped through holes 112, the elastic member 120 is loosened, and the elastic member 120 restores its shape under the action of its own deformation force. The clamping members 121 pass through the strip-shaped through holes 112 and enter the clamping groove 111. The annular protruding portion 140 is located on the side of the elastic member 120 close to the card 131 and abuts against the elastic member 120, so as to stably limit the elastic member 120 on the outer side wall of the base 110, preventing the elastic member 120 from being separated from the base 110 from the opening 122 side of the clamping groove 111.

[0062] Referring to Figure 6 Preferably, the sterile cover interface 100 further comprises a limiting column 134. One end of the limiting column 134 is connected with the card 131, and the other end is connected with the clamping ring 132. When the clamping member 130 is in the first state, the clamping ring 132 is located in the clamping groove 111, and the end of the base 110 close to the card 131 abuts against the end of the limiting column 134 away from the card 131.

[0063] Referring to Figures 7-13In an embodiment, the sterile cover interface 100 further comprises a limiting portion 150, which is connected to the annular protruding portion 140 on the side close to the elastic member 120 and is spaced apart from the base 110, so that the part of the elastic member 120 abutting against the limiting portion 150 is located between the limiting portion 150 and the base 110. When the elastic member 120 is saved in material and is convenient to be sleeved outside the sidewall of the base 110, the elastic member 120 will have a larger opening 122. If the elastic member 120 is matched with the protruding ring 133 for many times, the elastic member 120 will be loose, and even the elastic member 120 will be separated from the base 110. The limiting portion 150 limits the elastic member 120 between the limiting portion 150 and the base 110, so as to prevent the elastic member 120 from being loose and causing unstable clamping of the elastic member 120 and the clamping ring 132, and to make the clamping of the sterile cover interface 100 more stable.

[0064] Referring to Figures 7-13 In an embodiment, the limiting portion 150 is an arc-shaped strip 151, and the elastic member 120 is adapted to the arc-shaped strip 151. Since the elastic member 120 is sleeved outside the sidewall of the base 110, the outer edge of the elastic member 120 is generally arc-shaped or partially arc-shaped. Therefore, the limiting portion 150 is arranged as the arc-shaped strip 151, so that the arc-shaped outer edge of the elastic member 120 abuts against and is adapted to the arc-shaped strip 151. The arc-shaped strip 151 can completely abut against the elastic member 120, so as to stably limit the elastic member 120. The arc-shaped strip 151 protrudes away from the elastic member 120.

[0065] Referring to Figure 2 and Figure 5 In an embodiment, the sterile cover interface 100 further comprises a position sensing assembly 160, which comprises a first sensing portion 161 and a second sensing portion 162. The first sensing portion 161 is arranged on the bottom wall of the clamping groove 111, and the second sensing portion 162 is arranged on the side of the clamping piece 131 close to the base 110 and is located in the clamping ring 132. The first sensing portion 161 is used to receive the signal emitted by the second sensing portion 162 to indicate the position of the clamping piece 130. When the clamping piece 130 is in the first state, the clamping ring 132 is located in the clamping groove 111. At this time, the first sensing portion 161 receives the signal emitted by the second sensing portion 162 and indicates to the operator that the clamping piece 130 has been inserted into the clamping groove 111, and the subsequent operation can be performed. When the clamping piece 130 is in the second state, the clamping ring 132 is separated from the base 110. At this time, the first sensing portion 161 cannot receive the signal emitted by the second sensing portion 162 and indicates to the operator that the clamping piece 130 is separated from the base 110, and the subsequent operation can be performed, thereby playing a role of prompting the operator. The operator can prevent the operator from performing operations such as surgery when the clamping piece 130 and the base 110 are clamped unstably, so as to prevent pollution and other adverse effects.

[0066] Specifically, the first sensing part 161 is a receiver and the second sensing part 162 is a transmitter, or the first sensing part 161 is a transmitter and the second sensing part 162 is a receiver.

[0070] Referring to Figure 7 , Figure 10 and Figure 13In an embodiment, the aseptic cover interface 100 further comprises a plurality of fasteners 174, the mounting plate 170 is provided with a plurality of first fastening holes 175, the base 110 is provided with a plurality of second fastening holes 176 at an end away from the clamping member 130, the plurality of fasteners 174, the plurality of first fastening holes 175 and the plurality of second fastening holes 176 are in one-to-one correspondence, and the fastener 174 is arranged through the first fastening hole 175 and the second fastening hole 176, so as to fix the mounting plate 170 to the end of the base 110 away from the clamping member 130.

[0071] Specifically, the fastener 174 is a screw or a bolt, so as to facilitate dismounting the mounting plate 170 from the base 110 for maintenance.

[0072] Preferably, the plurality of second fastening holes 176 are uniformly arranged around the circumference of the clamping groove 111, so as to uniformly distribute the fastening force of the plurality of fasteners 174 on the mounting plate 170, and improve the service life of the mounting plate 170 and the base 110.

[0073] Referring to Figures 7-9 In an embodiment, the elastic member 120 is annular and has an opening 122, and the plurality of clamping members 121 are two clamping rods 123, one end of one clamping rod 123 is connected to one end of the opening 122, and one end of the other clamping rod 123 is connected to the other end of the opening 122, the convex ring 133 is in friction with the two clamping rods 123, so as to elastically deform the two clamping rods 123 in opposite directions, so as to make the convex ring 133 enter or leave the clamping groove 111, wherein the clamping rod 123 is partially arranged in the clamping groove 111, and the outer diameter of the convex ring 133 is adapted to the inner diameter of the clamping groove 111, so as to facilitate the clamping and frictional engagement of the convex ring 133 and the clamping rod 123. In this embodiment, preferably, the two clamping rods 123 are arranged in parallel and symmetrically on both sides of the clamping ring 132.

[0074] Referring to Figures 10-12In another embodiment, the elastic element 120 is annular and has an opening 122 and multiple connection ports 124. The locking element 121 is a locking rod 123, with each locking rod 123 corresponding to one of the multiple connection ports 124. The two ends of the locking rod 123 are connected to the two ends of the connection ports 124 respectively. The locking rod 123 protrudes inward toward the elastic element 120. When fitting the elastic element 120, the elastic element 120 is first opened up. After the opening 122 is enlarged, the elastic element 120 is fitted onto the side of the annular protrusion 140 away from the card 131. Then, the locking element 121 is aligned with the strip-shaped through hole 112, and the elastic element 120 is released. The elastic element 120 recovers its shape under its own deformation force. The locking rod 123 protrudes inward from the elastic element 120 and passes through the strip-shaped through hole 112 into the locking groove 111. The convex ring 133 rubs against the surrounding locking rods 123, causing the locking rods 123 to elastically deform in a direction away from the axis of the elastic element 120. This allows the convex ring 133 to enter or disengage from the locking groove 111. The locking rods 123 are partially located within the locking groove 111, and the outer diameter of the convex ring 133 matches the inner diameter of the locking groove 111, facilitating the locking and frictional engagement between the convex ring 133 and the locking rods 123. In this embodiment, preferably, the multiple locking rods 123 are evenly arranged around the circumference of the locking ring 132, so that the resultant force of the multiple locking rods 123 on the convex ring 133 along the radial direction of the convex ring 133 is zero, allowing the multiple locking rods 123 to stably engage with the convex ring 133.

[0075] See Figures 1-13 This application also provides a sterile hood assembly 210, which includes: a cylindrical hood body 211 and a plurality of sterile hood interfaces 100. A base 110, one end of which is connected to the side of a robotic arm 212. A clip 131, the end of which faces away from the base 110, is connected to the side wall of the cylindrical hood body 211, and a retaining ring 132 is located inside the cylindrical hood body 211.

[0076] During the assembly of the aforementioned sterile hood assembly 210, firstly, one end of the base 110 is connected to the side of the robotic arm 212. Then, the elastic element 120 is fitted onto the outer periphery of the base 110. The locking element 121 passes through the strip-shaped through hole 112 and is partially located within the locking groove 111. The end of the locking element 130 facing away from the base 110 is connected to the side wall of the cylindrical hood 211. The operator holds the locking element 130 and slides the cylindrical hood 211 from the end of the robotic arm 212 closest to the patient onto the outer periphery of the robotic arm 212. Figure 1 Then insert the protruding ring 133 into the card slot 111, as follows. Figure 4 The friction between the protruding ring 133 and the locking member 121 causes the elastic member 120 to deform radially along the protruding ring 133, thereby allowing the protruding ring 133 to pass through multiple locking members 121 and enter the locking groove 111. At this time, the locking member 130 is in the first state, such as... Figure 2And 5 The convex ring 133 is located between the bottom wall of the clamping groove 111 and the clamping part 121. After the operation is completed, the operator holds the clamping part 130 from the outside of the cylindrical cover 211 and drives the convex ring 133 away from the clamping groove 111. The convex ring 133 rubs against the clamping part 121, so that the elastic part 120 is deformed in the radial direction of the convex ring 133, thereby enabling the convex ring 133 to pass through the plurality of clamping parts 121 and be separated from the clamping groove 111. At this time, the clamping part 130 is in the second state, as shown in FIG. 6B. Figure 3 The convex ring 133 is separated from the base 110. Finally, the operator holds the clamping part 130 and removes the cylindrical cover 211 from the end of the mechanical arm 212 close to the patient. At this time, the mechanical arm 212 is exposed and not covered by the cylindrical cover 211. The sterile cover interface 100 described above is fitted by the clamping part 130, the elastic part 120, and the clamping groove 111 of the base 110, so as to enable the cylindrical cover 211 to be sleeved on the outer periphery of the mechanical arm 212 and be fixed. After the operation is completed, the clamping part 130 is held and separated from the base 110, the elastic part 120 is deformed, and finally the clamping part 130 is separated from the base 110, so as to remove the cylindrical cover 211 from the mechanical arm 212. No magnetic maintenance is required for the metal. The mechanical structure for clamping and pulling out the card 131 is stable and will not cause the sterile cover to be contaminated or affect the operation due to demagnetization and other unexpected situations. In addition, the material of the sterile cover interface 100 can be set as a degradable elastic plastic material, so as to facilitate recycling.

[0077] Referring to Figure 1 Specifically, in an embodiment, the side of the card 131 away from the clamping ring 132 is attached to the inner side wall of the cylindrical cover 211.

[0078] In another embodiment, the cylindrical cover 211 is provided with an attachment hole smaller than the card 131. Since the cylindrical cover 211 is flexible, the card 131 can pass through the attachment hole and cover the attachment hole. The outer side wall of the cylindrical cover 211 is attached to the side of the card 131 close to the clamping ring 132, so that the operator does not need to hold the card 131 through the cylindrical cover 211, preventing the operator from exerting force on the cylindrical cover 211 and causing the cylindrical cover 211 to be damaged or loose due to contact with the card 131.

[0079] Specifically, a plurality of sterile cover interfaces 100 are uniformly arranged around the circumference of the cylindrical cover 211, so as to more stably fix the cylindrical cover 211 to the side of the mechanical arm 212.
