The following is a more detailed description of the specific implementation of this utility model in conjunction with specific embodiments:

[0042] like Figures 1 to 3As shown, an embodiment of the present invention provides a guide for installation on a functional component and for guiding the surgical direction of the functional component during surgery. In this embodiment, the functional component includes at least one of a straight file rod assembly, a curved file rod assembly, a straight rod assembly, or a curved rod assembly. Thus, in hip replacement surgery, it is necessary to perform precise filing of the pelvic acetabulum and precise implantation of the acetabular prosthesis. The acetabular filing and acetabular prosthesis implantation are performed based on the same base. The guide provided in this embodiment can be quickly assembled and disassembled from the functional component and has the function of guiding the surgical direction of the functional component. The following is an explanation through specific embodiments:

[0043] The guide of this embodiment includes:

[0044] The guide base 1 is provided with a mounting hole 11 for the functional component 10 to pass through;

[0045] The locking member 2 includes an unlocking sleeve 21 provided on the hole wall of the mounting hole 11, a locking sleeve 22 provided in the unlocking sleeve 21, a limiting sleeve 23 provided in the locking sleeve 22, and a locking pin 24 provided on the limiting sleeve 23; the limiting sleeve 23 is provided with a locking hole 231 for accommodating the locking pin 24, the locking hole 231 being connected to the mounting hole 11, and the locking pin 24 being able to move radially in the locking hole 231; when the locking sleeve 22 moves to the locked position relative to the limiting sleeve 23, it pushes the locking pin 24 to protrude out of the locking hole 231, so that the locking pin 24 locks the functional component 10; when the unlocking sleeve 21 moves to the unlocking position relative to the limiting sleeve 23, it drives the locking pin 24 to retract into the locking hole 231, so that the locking pin 24 unlocks the functional component 10;

[0046] The tracer fixing member 3 is provided on the guide base 1 and is used to fix the tracer.

[0047] Here, it can be understood that the guide base 1 refers to a base for connecting to the functional component 10; the guide base 1 is provided with a mounting hole 11, and the mounting hole 11 is used to mount the functional component 10. Specifically, the functional component 10 is inserted into the mounting hole 11, and both ends of the functional component 10 are exposed outside the mounting hole 11.

[0048] The locking member 2 is a component used to lock the functional component 10 in the mounting hole 11; the locking member 2 includes an unlocking sleeve 21, a locking sleeve 22, a limiting sleeve 23 and a locking pin 24;

[0049] The unlocking sleeve 21 is a sleeve for unlocking the functional component 10. The unlocking sleeve 21 is provided on the hole wall of the mounting hole 11. The unlocking sleeve 21 can move relative to the limiting sleeve 23. The locking sleeve 22 is a sleeve for locking the functional component 10. The locking sleeve 22 is provided inside the locking sleeve 22.

[0050] The locking sleeve 22 is a sleeve for locking the functional component 10 , and the locking sleeve 22 is arranged inside the unlocking sleeve 21 ;

[0051] The limiting sleeve 23 is a component used to limit the locking pin 24, allowing the locking pin 24 to move within a preset range, thereby locking and unlocking the functional component 10. The limiting sleeve 23 is disposed inside the unlocking sleeve 21 and has a locking hole 231 formed therein. The locking hole 231 is used to accommodate the locking pin 24 and is connected to the mounting hole 11.

[0052] The locking pin 24 is a member for locking and unlocking the functional component 10. The locking pin 24 can move radially within the locking hole 231 along the guide base 1. In this way, the locking pin 24 can protrude out of the locking hole 231, so that the locking pin 24 locks the functional component 10. Here, the functional component 10 is provided with a locking structure 101, for example, the locking structure 101. The locking pin 24 protrudes out of the locking hole 231, so that the locking pin 24 can be snapped into the locking structure 101. The limiting effect between the locking structure 101 and the locking pin 24 fixes the functional component 10 relative to the guide base, thereby achieving the locking of the functional component 10.

[0053] The locking sleeve 22 can be moved relative to the limiting sleeve 23 to a locked position. When the locking sleeve 22 moves to the locked position, the locking sleeve 22 pushes the locking pin 24, causing the locking pin 24 to protrude out of the locking hole 231, thereby enabling the locking pin 24 to be engaged with the locking structure 101 of the functional component 10, thereby locking the functional component 10. When the unlocking sleeve 21 moves relative to the limiting sleeve 23 to the unlocking position, it drives the locking pin 24 to retract into the locking hole 231, so that the locking pin 24 unlocks the functional component 10.

[0054] The tracer fixing member 3 refers to a fixing component for fixing the tracer; the tracer fixing member 3 is arranged on the guide base 1.

[0055] The working principle of the guide provided in this embodiment is as follows:

[0056] Alternatively, the functional component 10 is inserted into the mounting hole 11 of the guide base, wherein the locking structure 101 of the functional component 10 is moved to a position facing the locking hole 231, and the locking sleeve 22 is moved to the locking position, so that the locking pin 24 protrudes out of the locking hole 231, and then the locking pin 24 can be engaged with the locking structure 101, thereby locking the functional component 10;

[0057] Move the unlocking sleeve 21 to the unlocking position so that the locking pin 24 can be retracted into the locking hole 231 , so that the locking pin 24 can be disengaged from the locking structure 101 , thereby unlocking the functional component 10 ;

[0058] The tracer is mounted on the tracer fixture 3 , thereby achieving positioning tracking of the functional component 10 .

[0059] By adopting the above technical solution, the functional component 10 and the guide are quickly disassembled and assembled, the positioning and tracking of the functional component 10 during surgery are achieved, and the accuracy of positioning is improved.

[0060] In one embodiment, a locking cavity for accommodating the locking sleeve 22 is provided between the unlocking sleeve 21 and the limiting sleeve 23, and the locking hole 231 connects the locking cavity and the mounting hole 11. The radial length of the locking hole 231 is smaller than the radial length of the locking pin 24. The locking sleeve 22 is provided with a locking end 221, and the locking end 221 can move in the locking cavity. When the locking end 221 moves to the locking position, it pushes the locking pin 24 so that the locking pin 24 protrudes out of the locking hole 231.

[0061] Here, it can be understood that the locking cavity refers to a cavity for the locking sleeve 22 to move; the locking cavity is formed between the unlocking sleeve 21 and the limiting sleeve 23, and the locking sleeve 22 is located between the unlocking sleeve 21 and the limiting sleeve 23, so that the locking sleeve 22 can move in the locking cavity; the locking hole 231 connects the locking cavity and the mounting hole 11, and the radial length of the locking hole 231 in the guide base is smaller than the radial length of the locking pin 24; the locking sleeve 22 is provided with a locking end 221, and the locking end 221 can move with the locking sleeve 22, and when the locking end 221 moves to the locking position, the locking end 221 pushes the locking pin 24, so that the locking pin 24 protrudes out of the locking hole 231.

[0062] By adopting the above technical solution, the locking pin 24 locks the functional component 10.

[0063] In one embodiment, the locking hole 231 extends obliquely from the locking end 221 along an axis close to the mounting hole 11 .

[0064] Here, it can be understood that the locking hole 231 is set at an angle, that is, the depth direction of the locking hole 231 forms an angle less than 90° with the axis of the guide base, so that the hole wall of the locking hole 231 can work together with the locking end 221 to drive the locking pin 24 to move in a preset direction.

[0065] By adopting the above technical solution, the locking hole 231 can guide the moving direction of the locking pin 24, so that the locking pin 24 moves in a directional manner, thereby improving the smoothness of the movement of the locking pin 24.

[0066] In one embodiment, the unlocking sleeve 21 is provided with an unlocking end 211 in the locking cavity for unlocking the locking pin 24. The unlocking end 211 is provided with an unlocking hole for accommodating the locking pin 24. The unlocking end 211 can move in the locking cavity. When the unlocking end 211 moves to the unlocking position, the unlocking hole is opposite to the locking hole 231, so that the locking pin 24 can retract into the locking hole 231.

[0067] Here, it can be understood that the unlocking sleeve 21 is provided with an unlocking end 211, which is used to unlock the functional component 10; the unlocking end 211 is located in the locking cavity, and at the same time, the unlocking end 211 can follow the unlocking sleeve 21 to move relative to the limiting sleeve 23 in the locking cavity; the unlocking end 211 is provided with an unlocking hole, and when the unlocking end 211 moves to the unlocking position, the unlocking hole is opposite to the locking hole 231, that is, the locking end 221 no longer pushes the locking pin 24, and the locking pin 24 can retract into the locking hole 231.

[0068] By adopting the above technical solution, the locking sleeve 22 unlocks the functional component 10.

[0069] In one embodiment, the guide also includes an unlocking elastic member 25 connected to the unlocking sleeve 21 and a locking elastic member 26 connected to the locking sleeve 22. The unlocking elastic member 25 is used to drive the unlocking sleeve 21 to move to the unlocking position; the locking elastic member 26 is used to drive the locking sleeve 22 to move to the locking position.

[0070] Here, it can be understood that the unlocking elastic member 25 refers to an elastic member that provides elastic force for the unlocking sleeve 21 to move to the unlocking position, and the unlocking elastic member 25 includes but is not limited to a spring; the locking elastic member 26 refers to an elastic member that provides elastic force for the locking sleeve 22 to move to the locking position, and the locking elastic member 26 includes but is not limited to a spring.

[0071] By adopting the above technical solution, the unlocking elastic member 25 is used to provide elastic force for the unlocking sleeve 21 to move, and the locking elastic member 26 is used to provide elastic force for the locking sleeve 22 to move, so that the unlocking sleeve 21 and the locking sleeve 22 have the function of automatic movement.

[0072] It needs to be further explained that the unlocking sleeve 21 is also connected to an unlocking handle 27, which is for the user to hold. The user can push and pull the unlocking handle 27. When no external force is applied to the unlocking handle, the locking elastic member 26 drives the locking sleeve 22 to move to the locked position and maintains it in the locked position; and when the user pulls the unlocking handle 27, the unlocking handle 27 drives the unlocking sleeve 21 to move to the unlocked position and maintains it in the unlocked position; the locking sleeve 22 and the unlocking sleeve 21 can be maintained in a preset position by setting a limiting structure, for example, setting a limiting block, and realizing the limiting effect by the friction between the limiting block and the hole wall of the mounting hole 11.

[0073] In one embodiment, the locking member 2 further includes a bearing 29 disposed between the limiting sleeve 23 and the wall of the mounting hole 11 .

[0074] Here, it can be understood that a bearing 29 is provided between the limiting sleeve 23 and the hole wall of the mounting hole 11 to facilitate the rotation of the rotating sleeve 28 around the axis, thereby enabling the functional component 10 to rotate around the axis.

[0075] By adopting the above technical solution, the functional component 10 and the guide base 1 are facilitated to rotate relative to each other, which is beneficial to the operation of the functional component 10.

[0076] like Figure 4 As shown, in one embodiment, a limiting step 111 for limiting the bearing 29 is provided on the wall of the mounting hole 11 , and a gap adjustment gasket 112 is detachably provided between the limiting step 111 and the bearing 29 .

[0077] Here, it can be understood that the relative position of the rotating sleeve 28 and the limiting sleeve 23 in the axial direction is adjustable, so that the axial position of the functional component 10 can be adjusted after being fixed to the guide, making the position of the functional component 10 adjustable.

[0078] By adopting the above technical solution, the flexibility of position adjustment of the functional component 10 is improved.

[0079] In one embodiment, one end of the guide base 1 is provided with a mating groove 113 for mating with the functional component 10 .

[0080] Here, it can be understood that the functional component 10 is provided with a bearing 29 installed in the matching groove 113, so that the two bearings 29 jointly support the rotation of the functional component 10 around the axis.

[0081] By adopting the above technical solution, the stability of the functional component 10 when rotating around the axis is improved.

[0082] In one embodiment, there are two tracer fixing members 3 , and the two tracer fixing members 3 are symmetrically arranged on both sides of the guide base 1 about the axis of the guide base 1 .

[0083] Here, it can be understood that the guide is installed at the end of the surgical robot's robotic arm, and is installed in left or right modes, corresponding to the left or right side of the human body during surgery. Therefore, the two tracer fixings 3 on the guide base 1 correspond to the left and right sides of the human body respectively.

[0084] By adopting the above technical solution, the applicability of the guide is improved.

[0085] In a second aspect, a surgical auxiliary instrument is provided, comprising a functional component 10 and the above-mentioned guide, wherein the functional component 10 comprises at least one of a straight file rod assembly, a curved file rod assembly, a straight rod assembly or a curved rod assembly, and the functional component 10 is detachably mounted on the guide.

[0086] By adopting the above technical solution, on the basis of having the advantages of the guide device of the above embodiment, the surgical auxiliary instrument of this embodiment also has the advantage of strong applicability.

[0087] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
