Description

Technical Field

[0001] The utility model belongs to the field of medical equipment and relates to a power source power supply structure for a surgical mechanical arm trolley. Background Art

[0002] In orthopedic navigation surgery for joint replacement, a surgical trolley is a commonly used device by doctors. The trolley is equipped with a robotic arm, on which a variety of power tools can be installed. Driven by the robotic arm and a power source, surgeries can be performed in various scenarios such as the hip joint and knee joint.

[0003] In the existing installation method of power sources and power tools, the power supply of the power source comes from a trolley or an external power supply, that is, the power cord on the power source is guided to the trolley for connection, or guided to a power port at a location outside the trolley. In this method, the power cord of the power source is too long and is prone to drooping and shaking. During the surgical preparation process or work process, the power cord may hook other equipment and pedestrians, causing a high probability of risk of cable pulling, crushing, and tripping pedestrians.

[0017] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0018] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0019] All directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, horizontal, vertical...) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0020] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of the present invention may actually be an approximately parallel relationship, and the vertical relationship may actually be an approximately vertical relationship.

[0021] The utility model provides a power supply structure for a power source applied to an operating trolley loaded with a robotic arm. The trolley is mainly used for carrying the robotic arm. A power tool can be installed at the end of the robotic arm to perform operations on a hip joint, a knee joint, etc. A power source is arranged on the power tool as an action driving element.

[0022] In this embodiment, as an example, the power tool is a grinding rod 2, and the power source is a bone drill 3. In the traditional installation structure of the bone drill 3, the power supply of the bone drill 3 comes from a trolley or an external power supply, that is, the power cord on the bone drill 3 is guided to the trolley for connection, or guided to a power port at a location outside the trolley. In this way, the power cord of the bone drill 3 is too long and is prone to drooping and shaking. During the surgical preparation process or the work process, the power cord of the bone drill 3 may be hooked on other equipment and pedestrians, causing a high probability of risk of cable pulling, crushing, and tripping pedestrians.

[0023] Furthermore, the file rod 2 used in surgical operations must be sterilized before the operation, and the bone drill 3 connected thereto also needs to be sterile. The traditional power cord of the bone drill 3 is connected to a non-sterile trolley. Therefore, before each operation, the bone drill 3 needs additional sterilization treatment before being connected to the file rod 2 for use, which makes the preoperative preparation work too cumbersome.

[0024] Reference Figure 1 In this embodiment, a bracket 1 is installed at the end of the mechanical arm, and the end of the bracket 1 is used to pass the grinding file rod 2 and realize bearing-type rotation fixation with the grinding file rod 2, which serves as a rotating base of the grinding file rod 2. A grinding file head is arranged at the front end of the grinding file rod 2, and a connecting shaft 21 is arranged at the rear end of the grinding file rod 2. The connecting shaft 21 is tightly matched with the driving end of the bone drill 3, so that the bone drill 3 can drive the rotation of the grinding file rod 2.

[0025] Specifically, an aviation plug terminal 11 is provided around the bracket 1, and the aviation plug terminal 11 draws power from the robotic arm through the inside of the bracket 1, that is, the robotic arm has a power supply function, and an adapter 4 is provided at the bottom of the bone drill 3. The adapter 4 is provided with a power cord and a plug 41, which are used to connect to the aviation plug terminal 11 to supply power to the bone drill 3.

[0026] Reference Figure 2 A mounting plane is arranged at the bottom of the bone drill 3, and a groove 31 is arranged on the circumferential side of the mounting plane. The groove 31 is preferably in a U-shaped structure. A contact surface that abuts against the mounting plane is formed at the top of the adapter 4. A flange 42 is protruded on the circumferential side of the abutting surface. The flange 42 is preferably a U-shaped structure that matches the U-shaped groove 31. The flange 42 is inserted into the groove 31 to achieve matching, and the adapter 4 is limited in the circumferential direction and at the bottom through the groove 31.

[0027] The adapter 4 is also provided with a locking plate 43, one end of which is hinged to the adapter 4, and a spring 44 is arranged below the locking plate 43, and both ends of the spring 44 are respectively connected to the locking plate 43 and the adapter 4, and the spring 44 provides an upward elastic force to the locking plate 43, and a protrusion 431 is arranged on the top of the locking plate 43, and a concave hole 32 is provided on the mounting plane for the protrusion 431 to be inserted upwardly. After the adapter 4 is inserted into the groove 31 through the flange 42 for engagement, the locking plate 43 is lifted up under the action of the spring 44 so that the protrusion 431 is inserted into the concave hole 32, thereby limiting the adapter 4 in the matching direction of the flange 42 and the groove 31 to prevent it from coming out in this direction, thereby finally achieving the fixing effect of the adapter 4 and the bone drill 3.

[0028] When disassembly is required, the locking plate 43 is pressed downward to make the protrusion 431 escape from the concave hole 32 , and the adapter 4 can be pulled out in the opposite direction of the matching direction of the groove 31 and the flange 42 .

[0029] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
