Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a tool for surgical navigation robots, specifically a quick one-way installation and connection device. Background Technology

[0002] As people pay increasing attention to their health, the demand for using robotic technology to assist surgery in specific scenarios is rising. Surgical robots require the coordinated use of robotic arms and surgical instruments to help doctors complete procedures. However, during the development of surgical navigation robots, it was discovered that many surgical instruments cannot be directly connected to the end effector of the robot's robotic arm, requiring corresponding adapters for connection and use.

[0003] Therefore, there is an urgent need for a connecting device that connects to the end of a robotic arm at one end and enables the rapid installation and clamping of surgical instruments or accessories at the other end. Summary of the Invention

[0004] To address the problems described in the background section, this invention provides a rapid unidirectional installation and connection device that enables the rapid unidirectional installation of a tracer onto the tool end of a surgical robot arm. This device is simple in structure and easy to disassemble.

[0005] The technical solution of the present invention is as follows: a quick one-way installation and connection device, comprising a robotic arm tool end, a base flange, a surgical instrument connector, a tracer, and connecting components for connecting and fixing the above-mentioned devices; wherein one end of the base flange is used to connect to the robotic arm tool end, and the other end is used to install surgical instruments; the connecting components include: a one-way pin, a one-way spring, a bottom sealing plate, a sealing plate screw, a positioning pin, a flange screw, a loosening button, a spring, an insulating pad, an insulating positioning component, an insulating screw sleeve, and an instrument screw.

[0006] Preferably, the base flange has four symmetrically arranged inclined slots at the center of the end face used to connect the tool end of the robotic arm. The one-way spring and the one-way pin are installed in the inclined slots, and the one-way spring has a preload and is in a compressed state when installed.

[0007] Furthermore, the base flange needs to have a mounting groove on the end face of the tool end of the robotic arm, and the bottom sealing plate is installed and fixed in the mounting groove by the sealing plate screws.

[0008] Furthermore, the base flange needs to have a locating pin hole on the end face of the tool end of the robotic arm, and the locating pin is installed in the locating pin hole.

[0009] Furthermore, the end face of the base flange for mounting surgical instruments is provided with an opening groove. The loosening button can contact the one-way pin inside the base flange through the opening groove, and the one-way pin can overcome the elastic force of the one-way spring under the push of the loosening button, thereby sliding in the inclined groove on the base flange.

[0010] Furthermore, the end face of the base flange for mounting surgical instruments is provided with fixing screw holes for connecting and fixing with the surgical instrument connector.

[0011] Furthermore, the base flange has a guide groove on its side for inserting the pin of the tracer. The guide groove forms an acute angle with the inclined groove of the base flange and has a certain dimensional interference.

[0012] Furthermore, the base flange is fixed to the tool end of the robotic arm by the flange bolts.

[0013] Furthermore, the insulating pad has a limiting groove to limit the sliding range of the loosening button, and a square opening in the middle of the insulating pad is provided for installing the insulating positioning member in the square opening.

[0014] Furthermore, the insulating positioning member has installation positioning features that match the base flange and the surgical instrument connector, and serves as a transitional connector between the base flange and the surgical instrument connector to ensure high-precision positioning and installation.

[0015] Furthermore, the instrument screw is fitted with the insulating screw sleeve, and the instrument screw is installed into the fixing screw hole of the base flange through the mounting groove of the surgical instrument connector and the insulating pad, thereby realizing the connection and fixation of the base flange and the surgical instrument connector.

[0016] Furthermore, the insulating pad, the loosening button, the insulating positioning component, and the insulating screw sleeve are all made of non-metallic insulating materials to achieve insulation between the base flange and the surgical instrument connector.

[0017] Furthermore, the tracer includes a tracer element, as well as mounting positioning features and a pin that mate with the base flange.

[0018] Furthermore, the positioning feature of the tracer is rectangular, which can restrict its rotation direction.

[0019] The installation method of the quick one-way installation connection device of the present invention is as follows: When the tracer's pin is inserted into the guide groove on the side of the base flange, due to the interference between the one-way pin in the inclined groove of the base flange and the pin, the pin will push the one-way pin to slide down the inclined groove until the gap between the one-way pins on the left and right sides is large enough for the pin to be inserted. At this time, the one-way pin will not slide inward anymore and will remain in place. At this time, the base flange and the recessed surface of the tracer are in contact, which means the installation is complete. The one-way spring is compressed after the tracer is inserted into place, ensuring that the one-way pin can always be in a state of compression contact with the pin of the tracer. When a force is applied to pull the pin outward, it will simultaneously drive the one-way pin to slide outward of the inclined groove of the base flange. Due to the limitation of the pin and the interference with the inclined groove of the base flange, the size is insufficient for the one-way pin to slide outward, thereby achieving the effect of one-way locking.

[0020] The disassembly method of the quick one-way installation and connection device of the present invention is as follows: After use, if the tracer needs to be removed, simply press the loosening button to push the one-way pin to continue sliding into the inclined groove. The one-way pin will no longer be in contact with the pin of the tracer, and the tracer can be freely inserted and removed.

[0021] The quick unidirectional installation and connection device provided by this invention enables the rapid installation of a tracer onto the tool end of a surgical robot arm. It features a unidirectional structure with stepless unidirectional movement, eliminating any gaps that could allow for reverse loosening. Furthermore, the invention is simple to use. During installation, simply insert the tracer's pin into the guide groove on the side of the base flange, ensuring contact between the base flange and the tracer's mating surface. During disassembly, simply press the loosening button and push the unidirectional pin into the inclined groove. Once the unidirectional pin is no longer in contact with the tracer's pin, the tracer can be freely inserted or removed. Attached Figure Description

[0041] To better understand the present invention, the connecting device of the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0042] like Figure 1 As shown, the present invention provides a quick one-way installation and connection device, including a base flange 1, a tracer 2, a robotic arm tool end 8, a surgical instrument connector 14, and connecting components for connecting and fixing the above-mentioned devices; one end of the base flange 1 is used to connect to the robotic arm tool end 8, and the other end is used to connect to a surgical instrument through the surgical instrument connector; the connecting components include: a one-way pin 3, a one-way spring 4, a bottom sealing plate 5, a sealing plate screw 6, a positioning pin 7, a flange screw 9, an insulating pad 10, a loosening button 11, a spring 12, an insulating positioning component 13, an insulating screw sleeve 15, and an instrument screw 16.

[0043] As an optional implementation method, such as Figure 2 , 4 As shown, the base flange 1 has four inclined grooves 101 on its end face for connecting the tool end 8 of the robotic arm. The one-way spring 4 and the one-way pin 3 are installed in the inclined grooves, and the one-way spring 4 has a preload when installed and is in a compressed state.

[0044] As an optional implementation method, such as Figure 5 As shown, the base flange 1 has an installation groove on its end face that needs to be installed onto the tool end 8 of the robotic arm, and the bottom sealing plate 5 is installed and fixed in the installation groove by the sealing plate screws 6.

[0045] As an optional implementation, the base flange 1 needs to be installed on the end face of the tool end 8 of the robotic arm, which has a positioning pin hole 102, and the positioning pin 7 is installed in the positioning pin hole 102.

[0046] As an optional implementation method, such as Figure 3 As shown, the end face of the base flange 1 for mounting surgical instruments is provided with an opening groove 103. The loosening button 11 can contact the one-way pin 3 inside the base flange 1 through the opening groove 103, and the one-way pin 3 can overcome the elastic force of the one-way spring 4 under the push of the loosening button 11, thereby sliding in the inclined groove 101 on the base flange 1.

[0047] As an optional implementation, the end face of the base flange 1 for mounting surgical instruments is provided with fixing screw holes 104 for connecting and fixing with the surgical instrument connector 14.

[0048] As an optional implementation method, such as Figure 6 As shown, the base flange 1 has a guide groove 105 on its side for the insertion of the pin of the tracer 2. The guide groove forms an acute angle with the inclined groove 101 of the base flange 1 and has a certain dimensional interference.

[0049] like Figure 7 As shown, the base flange 1 is fixed to the robotic arm tool end 8 by the flange screws 9.

[0050] As an optional implementation method, such as Figure 8 As shown, the insulating pad 10 has a limiting groove 1001 to limit the sliding range of the loosening button 11, and the insulating pad 10 has a square opening in the middle for installing the insulating positioning member 13 in the square opening.

[0051] As an optional implementation method, such as Figure 9 As shown, the insulating positioning member 13 has installation positioning features that match the base flange 1 and the surgical instrument connector 14, and serves as a transitional connector between the base flange 1 and the surgical instrument connector 14 to ensure high-precision positioning and installation.

[0052] As an optional implementation method, such as Figure 11 As shown, the instrument screw 16 is fitted onto the insulating screw sleeve 15, and through the mounting grooves of the surgical instrument connector 14 and the insulating pad 10, the instrument screw 16 is installed into the fixing screw hole 104 of the base flange 1, thereby realizing the connection and fixation of the base flange 1 and the surgical instrument connector 14. The overall installation diagram is shown below. Figure 12 As shown.

[0053] As an optional implementation, the insulating pad 10, the loosening button 11, the insulating positioning component 13, and the insulating screw sleeve 15 are all made of non-metallic insulating materials to achieve insulation between the base flange 1 and the surgical instrument connector 14.

[0054] As an optional implementation method, such as Figure 13 As shown, the tracer 2 includes a tracer element, a mounting and positioning feature that mates with the base flange, and a pin 201.

[0055] As an optional implementation, the positioning feature on which the tracer 2 is mounted is rectangular, which can restrict its rotation direction.

[0056] like Figure 14 As shown, the present invention also provides an installation method for a quick one-way installation connection device. The steps are as follows: during the process of inserting the pin 201 of the tracer 2 into the guide groove 105 on the side of the base flange, since the one-way pin 3 in the inclined groove 101 of the base flange interferes with the pin 201, the pin 201 will push the one-way pin 3 to slide down the inclined groove 101 until the gap between the one-way pins 3 on the left and right sides is large enough for the pin 201 to be inserted. The one-way pin 3 will then stop sliding inward and remain in place. At this time, the base flange 1 and the mating surface of the tracer 2 are in contact, which means the installation is complete.

[0057] As an optional implementation, the one-way spring 4 is compressed after the tracer 2 is inserted into place, ensuring that the one-way pin 3 remains in a pressed contact with the pin 201 of the tracer 2. When a force is applied to pull the pin 201 outward, it simultaneously causes the one-way pin 3 to slide outward of the inclined groove 101 of the base flange 1. Due to the restriction of the pin 201 and its interference with the inclined groove 101 of the base flange 1, the size is insufficient for the one-way pin 3 to slide outward, thereby achieving a one-way locking effect.

[0058] The present invention provides a method for disassembling a quick one-way installation connection device. The steps are as follows: after use, if the tracer 2 needs to be removed, simply press the loosening button 11 to push the one-way pin 3 to continue sliding into the inclined groove 101. The one-way pin 3 will no longer be in contact with the pin 201 of the tracer 2, and the tracer 2 can be freely inserted and removed.

[0059] The quick unidirectional installation and connection device provided by this invention enables the rapid installation of a tracer onto the tool end of a surgical robot arm. It features a unidirectional structure with stepless unidirectional movement, eliminating any gaps that could allow for reverse loosening. Furthermore, the invention is simple to use. During installation, simply insert the tracer's pin into the guide groove on the side of the base flange, ensuring contact between the base flange and the tracer's mating surface. During disassembly, simply press the loosening button and push the unidirectional pin into the inclined groove. Once the unidirectional pin is no longer in contact with the tracer's pin, the tracer can be freely inserted or removed.

[0060] Although the invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict.
