Description

Technical Field

[0001] This invention relates to the field of orthopedic surgical equipment technology, specifically to a rapid positioning and clamping device for orthopedic surgery. Background Technology

[0002] During robot-assisted surgery, a reflective positioning device is needed to provide precise positioning of the surgical site. Currently, this function can be achieved using complex bone pin clamps and screw fixation. However, the current solution has some problems. For example, doctors need to adjust the position of the reflective positioning device or replace it during use. Therefore, the current solution cannot achieve quick disassembly, making adjustment difficult. In addition, the current solution usually uses a single bone pin clamp to fix the bone pin, which does not provide a stable fixation effect. Summary of the Invention

[0003] In view of the shortcomings of the prior art described in the background section, the present invention provides a rapid positioning and clamping device for orthopedic surgery, which solves the problems of unstable bone pin clamping and positioning in the prior art, and the inability of the reflective positioning device to be quickly disassembled, resulting in difficulty in adjustment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a rapid positioning and clamping device for orthopedic surgery, comprising: a reflective positioning component, a reflective array fixation clamp component, and a bone pin fixation clamp component.

[0005] The reflective positioning component includes: a reflective positioning array, a first fastening magnet, and an array connector;

[0006] The reflective array clamp assembly includes: a spherical adjustment component, an array fixing base, a second fastening magnet, a magnet cover, a magnet locking screw, a first spring front end fixing ball, a first spring, a first spring cover, and a connecting rod;

[0007] The bone pin fixation clamp assembly includes: a first bone pin clamp outer frame, a second bone pin clamp outer frame, a cylindrical support, a third spring, a fixing screw, a fixing ball at the front end of the second spring, a second spring, a second spring cap, a bone pin, and a bone pin fixing screw;

[0008] Furthermore, the reflective positioning component and the reflective array clamp component are connected, enabling quick locking and disassembly; the reflective array clamp component and the bone pin fixing clamp component are connected, and the position of the reflective array clamp component can be quickly adjusted and fixed by rotating the fixing screw of the bone pin fixing clamp component.

[0009] Furthermore, the bottom of the reflective positioning array is provided with a groove for connecting with the array connector.

[0010] Furthermore, the array connector includes a first array connector and a second array connector, wherein the first array connector is a hollow cylinder, the second array connector is a cylinder with a symmetrical cross section, a circular groove is formed in the middle of the cylinder, and the diameter of the hollow cylinder of the first array connector and the diameter of the circular groove of the second array connector are equal.

[0011] Furthermore, an arc-shaped groove is also provided on the symmetrical cross-section of the second array connector.

[0012] Furthermore, the first fastening magnet is assembled in the circular groove of the array connector, and the first array connector of the array connector is connected and fixed to the bottom groove of the reflective positioning array.

[0013] Furthermore, the array fixing base and the connecting rod are integrally formed.

[0014] Furthermore, the bottom of the array fixing base is provided with a groove, and the magnet cover is provided with four holes. The magnet locking screw locks the second fastening magnet in the bottom groove of the array fixing base through the holes of the magnet cover.

[0015] Furthermore, the array fixing base has two symmetrically arranged opposite holes on its left and right sides for installing the first spring front fixing ball, the first spring, and the first spring cover.

[0016] Furthermore, the top of the array fixing base is provided with a groove, and the array connector of the reflective positioning component is installed in the groove. The magnetic force of the first fastening magnet and the second fastening magnet provides a first locking force. At this time, the front end fixing ball of the first spring cooperates with the arc-shaped groove of the array connector to provide a second locking force.

[0017] Furthermore, the outer frame of the first bone needle clamp is composed of a main frame and a cylindrical structure. The main frame has a through hole along its axial direction, and the fixing screw is installed in the through hole. The cylindrical structure has symmetrical grooves.

[0018] Furthermore, a round hole is provided at the top of the main frame of the first bone needle clamp outer frame for installing the bone needle, and a first slot is provided on the corresponding position on its side. The bone needle fixing screw fixes the bone needle in the round hole of the first bone needle clamp outer frame through the first slot.

[0019] Furthermore, the cylindrical support is composed of a first cylinder and a second cylinder. The second cylinder has two symmetrical protrusions on its axial side. When the first cylinder is assembled inside the cylindrical structure of the outer frame of the first bone needle clamp and abuts against the fixing screw, the two protrusions on the side of the second cylinder can cooperate with the grooves of the cylindrical structure of the outer frame of the first bone needle clamp.

[0020] Furthermore, one end of the third spring abuts against the cylindrical support member, and the other end abuts against the spherical adjusting member. The spherical adjusting member passes through the outer frame of the second bone needle clamp and is fixedly connected to the connecting rod.

[0021] Furthermore, the main frame side of the first bone needle clamp is also provided with symmetrical second holes and slots. The second spring front end fixing ball, the second spring, and the second spring cap are assembled in the second holes and slots, and the second spring front end fixing ball is located in the annular groove around the fixing screw, which is used to limit the movement of the fixing screw.

[0022] This invention provides a rapid positioning and clamping device for orthopedic surgery, including a reflective positioning component, a reflective array fixation clamp component, and a bone pin fixation clamp component. It can realize the rapid installation and removal of the reflective positioning component, and the position of the reflective positioning component can be quickly adjusted during surgery.

[0023] The locking method of the reflective positioning component and the reflective array fixing clamp component is as follows: the reflective positioning component is placed in the groove of the array fixing base, and the reflective positioning component and the reflective array fixing clamp component are locked by the magnetic force of the first fastening magnet and the second fastening magnet, as well as the second locking force provided by the cooperation of the front end fixing ball of the first spring and the arc groove of the array connector.

[0024] When it is necessary to disassemble the reflective positioning component, simply hold the reflective positioning component and apply upward force. The first spring will contract, causing the fixing ball at the front end of the first spring to leave the arc-shaped groove of the reflective positioning component, thus enabling the quick disassembly of the reflective positioning component.

[0025] The locking method of the reflective array fixation clamp assembly and the bone pin fixation clamp assembly is as follows: tighten the fixing screw, so that the cylindrical support moves to the left and the third spring is compressed. At this time, the distance between the outer frame of the second bone pin clamp and the cylindrical support becomes smaller, and the spherical adjustment piece of the reflective array clamp assembly is clamped from the left and right directions to achieve the locking of the reflective array fixation clamp assembly and the bone pin fixation clamp assembly.

[0026] When the fixing screw is loosened, the rebound force of the third spring causes the cylindrical support to move to the right, and the distance between the outer frame of the second bone needle clamp and the cylindrical support increases. At this time, the spherical adjustment component of the reflective array clamp assembly can be adjusted, thereby realizing the rapid adjustment and positioning of the reflective array clamp assembly.

[0027] In addition, when the fixing screw is loosened, the annular groove of the fixing screw and the fixing ball at the front end of the second spring move relative to each other. Since the fixing ball at the front end of the second spring clamps the annular groove, the fixing screw will not fall off accidentally when it is loosened. Attached Figure Description

At this time, the first spring front end fixing ball 26 cooperates with the arc-shaped groove 133 of the array connector to provide a second locking force.

[0058] like Figure 7 As shown, the outer frame 31 of the first bone needle clamp is composed of a main frame 311 and a cylindrical structure 312. The main frame 311 has a through hole 313 in the axial direction, and the fixing screw 35 is installed in the through hole 313. The cylindrical structure 312 has symmetrical grooves 314.

[0059] As an optional implementation, the top of the main frame 311 of the first bone needle clamp is also provided with a round hole for installing the bone needle 39, and a first slot 315 is provided on the corresponding position on its side.

The first spring will contract, causing the fixing ball at the front end of the first spring to leave the arc-shaped groove of the reflective positioning component, thus enabling the quick disassembly of the reflective positioning component.

[0066] The locking method of the reflective array fixation clamp assembly and the bone pin fixation clamp assembly is as follows: tighten the fixing screw, so that the cylindrical support moves to the left and the third spring is compressed. At this time, the distance between the outer frame of the second bone pin clamp and the cylindrical support becomes smaller, and the spherical adjustment piece of the reflective array clamp assembly is clamped from the left and right directions to achieve the locking of the reflective array fixation clamp assembly and the bone pin fixation clamp assembly.

[0067] When the fixing screw is loosened, the rebound force of the third spring causes the cylindrical support to move to the right, and the distance between the outer frame of the second bone needle clamp and the cylindrical support increases.
