The convex wall 11231 and the protrusion 1113 are connected by a first fastener 1124 inserted into the first opening 11203 and the second opening 11101. The orientation of the first opening 11203 is parallel to the plane where the screen 1111 is located. The first fastener 1124 passes through the first opening 11203 and the second opening 11101 along the direction parallel to the plane where the screen 1111 is located to fix the display screen assembly 111 on the main bracket 112 in the direction parallel to the plane where the screen 1111 is located. In this application, the display screen assembly 111 is fixed to the screen bracket 1112. On the one hand, after the functional module 110 is inserted into the installation cavity 1204, the first fastener 1124 is hidden, making the first appearance surface 160 and the overall appearance of the medical device 10 more beautiful. On the other hand, since the housing 120 is provided with a first opening 1201, a second opening 1202 and a third opening 1203, the strength of the housing 120 is relatively small. If the display screen assembly 111 is only mounted on the housing 120, the housing 120 cannot provide good support for the display screen assembly 111.

[0077] Optionally, the shape of the locking member 144 can be plate-shaped, and the device body 30 can be composed of a functional module 110 and a housing 120. When the medical device 10 is locked to the plug-in box 20, most of the device body 30 is located in a semi-closed space, and the setting of the position of the operation key 146 is relatively demanding. If the operation key 146 is set on the device body 30, the space for holding the operation key 146 to unlock and remove the medical device 10 is small, resulting in a poor experience for the user; and if all the components of the locking structure 140 are set in the device body 30, it will occupy a large space in a relatively small medical device 10. By setting the operation key 146 on the handle 130, it is convenient to lock and unlock the medical device 10 with the plug-in box 20, and at the same time, the space utilization rate can be improved.

[0078] Furthermore, the locking structure 140 further includes a connecting member 141, a push rod 142, and a rocker 143. The operation key 146, the connecting member 141, the push rod 142, the rocker 143, and the locking member 144 are linked in sequence.

The length direction of the connecting portion 132 may be parallel to the length direction of the handle rod 1311. Two ends of the connecting portion 132 are respectively connected to one end of the first side arm 1312 away from the handle rod 1311 and one end of the second side arm 1313 away from the handle rod 1311. The operation key 146 may be installed on the first side arm 1312. The connecting member 141 may be installed on the first side arm 1312, and the length direction of the connecting member 141 may be consistent with the length direction of the first side arm 1312. The push rod 142 is installed on the connecting portion 132, and the length direction of the push rod 142 may be consistent with the length direction of the connecting portion 132.

[0080] Optionally, the device body 30 is provided with a second installation groove 1205. The locking member 144 is at least partially located in the second installation groove 1205. A locking portion 1441 protrudes from a side of the locking member 144 away from the device body 30. When the locking member 144 is in the first position, the locking portion 1441 protrudes from the second installation groove. When the locking member 144 is in the second position, the locking portion 1441 is received in the second installation groove.

[0081] Optionally, the elastic member 145 abuts between the locking member 144 and the housing 120.

The operation key 146 abuts against the connecting member 141. The operation key 146 abutting against the connecting member 141 means that the operation key 146 is in contact with the connecting member 141, and the operation key 146 exerts pressure on the connecting member 141 or the connecting member 141 exerts pressure on the operation key 146. Understandably, abutting is just a way of connection. In some other embodiments, the operation key 146 can also be connected to the connecting member 141 in other connection ways. Both ends of the push rod 142 abut against the connecting member 141 and the rocker 143 respectively. The end of the rocker 143 away from the push rod 142 abuts against the locking member 144. When a force is applied to the operation key 146, the operation key 146, the connecting member 141, the push rod 142, the rocker 143 and the locking member 144 are linked in sequence, so that the latching portion 1441 moves towards the housing 120 and is received in the second installation groove 1205. When the force applied to the operation key 146 is withdrawn, the latching portion 1441 can move away from the housing 120 under the elastic force of the elastic member 145 and protrude from the second installation groove 1205.

Specifically, the first rotating shaft 1433 and the second rotating shaft 1442 are respectively rotatably connected to the housing 120.

[0086] Optionally, when the locking member 144 is in the first position, the distance between the plane where the first portion 1431 is located and the bottom surface 123 of the second installation groove 1205 is less than the distance between the plane where the second portion 1432 is located and the bottom surface 123. When a force is applied to the operating key 146, the operating key 146 drives the first portion 1431 to rotate around the first rotating shaft 1433 through the connecting member 141 and the push rod 142, and further causes the second portion 1432 to rotate around the first rotating shaft 1433 in the direction close to the bottom surface 123, so that the locking member 144 rotates from the first position to the second position around the second rotating shaft 1442.

[0087] Further, the operating key 146 can drive the push rod 142 to move through the connecting member 141, so that the first portion 1431 drives the second portion 1432 to approach the housing 120 with the first rotating shaft 1433 as a fulcrum under the pressing of the push rod 142. Further, one end of the locking member 144 away from the second rotating shaft 1442 rotates towards the housing 120, so that the locking portion 1441 approaches the housing 120 and is received in the second installation groove 1205.

[0088] Further, as Figure 8As shown, the housing 120 includes a first plate 121 and a second plate 122 that are arranged opposite to each other, a second mounting groove 1205 is arranged on the first plate 121, a connection port 1209 is provided on the first side wall 1211 of the second mounting groove 1205 close to the first side plate 113, a first rotating shaft 1433 is parallel to the first side wall 1211, and a second rotating shaft 1442 is also parallel to the first side wall 1211, a first rotating shaft groove 1207 and a second rotating shaft groove 1208 are provided in the second mounting groove 1205, the first rotating shaft groove 1207 is arranged close to the connection port 1209, and the second rotating shaft groove 1208 can be arranged close to the second side wall 1212 of the second mounting groove 1205 away from the first side plate 113. The first rotating shaft 1433 is installed in the first rotating shaft groove 1207, and the first portion 1431 is passed through the connection port 1209. The second rotating shaft 1442 is installed in the second rotating shaft groove 1208, and a baffle 1213 protrudes from the second side wall 1212. The second rotating shaft groove 1208 can be defined by the second side wall 1212 and the baffle 1213. The notch of the second rotating shaft groove 1208 can be smaller than the diameter of the second rotating shaft 1442. The material of the baffle 1213 can be plastic or metal alloy material with certain elastic properties, so that the second rotating shaft 1442 can be snapped into the second rotating shaft groove 1208.

[0089] Furthermore, a limit strip 1214 is protruding from the second side wall 1212. The limit strip 1214 has a certain strength and its material may be hard plastic or metal alloy material. The limit strip 1214 is used to limit the movement of the second rotating shaft 1442 in a direction perpendicular to the bottom surface 123 to prevent the blocking strip 1213 from being deformed under the pressure of the second rotating shaft groove 1208 and thereby causing the second rotating shaft groove 1208 to detach from the second rotating shaft groove 1208.
