Description

A rapid disassembly and assembly system and method for MRI-PHIFU Technical Field

[0001] The present invention relates to the technical field of MRI-PHIFU, and in particular to a quick disassembly and assembly system and method for MRI-PHIFU. Background Art

[0002] There are many treatments for tumors, including medication, cryoablation, radiofrequency ablation, and surgery, but all leave wounds on the patient. High-intensity focused ultrasound (HIFU) with magnetic resonance imaging (MRI) leverages ultrasound's penetrability within the human body to focus energy directly on a focal point. Furthermore, with the precise scanning and positioning technology of MRI, MRI can achieve the goal of ablating lesions non-invasively.

[0003] To expand the treatment range, this technology requires the use of an MRI-compatible manipulator. However, the manipulator and its connecting cables are extremely cumbersome to the entire device, and the manipulator cannot be quickly assembled and disassembled from the coil, making movement extremely inconvenient and the installation and disassembly process extremely complex. Therefore, the successful design of a rapid assembly and disassembly mechanism for the manipulator used in MRI-PHIFU has important clinical significance for the development of therapeutic ultrasound in the treatment of various diseases.

[0004] Summary of the Invention

[0005] The purpose of the present invention is to provide a rapid disassembly and assembly system and method for MRI-PHIFU.

[0006] The object of the present invention can be achieved by the following technical solution: A rapid disassembly and assembly system for MRI-PHIFU, comprising: a coil, a mounting mechanism, a locking mechanism, and a base;

[0007] The mounting mechanism, the locking mechanism and the base are respectively connected to the coil;

[0008] The mounting mechanism is used to connect external devices;

[0009] The mounting mechanism, the locking mechanism and the base cooperate to detachably mount the external device on the coil.

[0010] Preferably, a locking platform is provided on the locking mechanism, and the mounting mechanism is locked and / or unlocked by rotating the locking platform.

[0011] Further preferably, the locking mechanism further comprises a base shaft and a handle;

[0012] The base is provided with a communication structure;

[0013] The locking platform is arranged on the base shaft, the base shaft is arranged on the communication structure, and the base shaft is connected to the handle.

[0014] More preferably, the locking mechanism further comprises: a left locking platform, a right locking platform, a left slot support platform and a right slot support platform;

[0015] The left groove supporting platform, the left locking platform, the right locking platform and the right groove supporting platform are sequentially arranged on the base shaft.

[0016] Preferably, when locking, the left locking platform and the right locking platform are rotated toward the mounting mechanism by the handle to lock the mounting mechanism, and then the base shaft is translated along the axis to confine the left slot support platform and the right slot support platform within the connecting structure.

[0017] Preferably, when unlocking, the base shaft is translated along the axis, and the left locking platform and the right locking platform are rotated in a direction away from the mounting mechanism by the handle.

[0018] In order to solve the problem in the prior art that a lot of time is required to assemble and disassemble the manipulator and the coil each time, the present invention designs a base and a locking mechanism. Through the coordinated design of the connecting structure on the base and the left locking platform, the right locking platform, the left slot support platform and the right slot support platform on the base shaft, the structure is simple and the locking and unlocking functions can be easily realized. The manipulator can be easily assembled and disassembled by cleverly rotating the handle.

[0019] Preferably, the mounting mechanism comprises: a connecting unit, a mounting plane and a locking plane;

[0020] The connection unit and the locking plane are disposed on the mounting plane. The connection unit is used to connect to an external device, the mounting plane is used to mate with the coil, and the locking plane is used to cooperate with the locking mechanism. To lock, the left and right locking platforms are rotated toward the mounting mechanism using the handle. Once fully rotated, the bottom surface of the locking plane abuts the top surfaces of the left and right locking platforms.

[0021] Further preferably, the connecting unit is arranged on one side of the mounting plane, and the locking plane is arranged at the bottom of the mounting plane.

[0022] Further preferably, the mounting mechanism further includes a positioning unit;

[0023] The coil is provided with a recessed plane matching the mounting plane and a positioning groove matching the positioning unit.

[0024] The present invention can achieve a good limiting effect on the installation mechanism through the coordinated design of the installation plane and the recessed plane, the positioning unit and the positioning groove, which is conducive to the stable fixation of the installation mechanism on the coil to avoid deviation, and can play a certain positioning and guiding role during the installation process.

[0025] More preferably, the positioning unit is arranged on the top of the installation plane.

[0026] Preferably, the base includes a coil connection unit and a threaded through hole;

[0027] The threaded through hole is provided on the coil connection unit, and the coil connection unit is detachably mounted on the coil through non-magnetic screws and the threaded hole on the coil.

[0028] Preferably, the mounting mechanism is arranged above the base, and the two do not interfere with each other.

[0029] Further preferably, the installation plane is provided with an avoidance gap at a position corresponding to the coil connection unit.

[0030] A rapid disassembly and assembly method for MRI-PHIFU, using the above system, comprises the following steps:

[0031] During assembly:

[0032] S1: Install the base with a locking mechanism on the coil;

[0033] S2: Install the mounting mechanism on the coil;

[0034] S3: Rotate the locking mechanism to lock the mounting mechanism onto the coil;

[0035] When disassembling:

[0036] A1: Rotate the locking mechanism to unlock the mounting mechanism;

[0037] A2: Remove the mounting mechanism from the coil.

[0038] Compared with the existing technology, the present invention solves the problem in the existing MRI-PHIFU system that the manipulator cannot be quickly disassembled and assembled with the coil, requires being fixed with screws, and is extremely inconvenient to move. It realizes modular assembly between the manipulator and the coil, greatly enhances the flexibility of the equipment, saves installation time, and thus improves the efficiency of the MRI-PHIFU system during the treatment process.

DETAILED DESCRIPTION

[0048] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are implemented based on the technical solution of the present invention, and provide detailed implementation methods and specific operating processes, but the protection scope of the present invention is not limited to the following embodiments.

[0049] Example 1

[0050] A quick disassembly and assembly mechanism for MRI-PHIFU comprises a coil 1, a mounting mechanism 2, a locking mechanism 3 and a base 4.

[0051] Among them, the mounting mechanism 2 and the base 4 can be detachably mounted on the coil 1, the locking mechanism 3 is set on the base 4, the mounting mechanism 2 is connected to an external device such as a manipulator 6, the mounting mechanism 2, the locking mechanism 3 and the base 4 cooperate to detachably set the manipulator 6 on the coil 1.

[0052] In this embodiment, the mounting mechanism, locking mechanism, and base are cooperatively arranged. The manipulator is connected via the mounting mechanism, and the locking mechanism is installed via the base. The mounting mechanism, coupled with the manipulator, is then locked and secured to the coil via the locking mechanism. This allows for rapid assembly and disassembly of the manipulator and coil, enabling modular transportation and storage of the manipulator and coil. This reduces on-site equipment assembly time, significantly improves equipment operation efficiency, and ensures the reliability of the MRI-PHIFU system during the treatment of tumors.

[0053] Example 2

[0054] A quick disassembly and assembly mechanism for MRI-PHIFU, as shown in FIG1 , includes a coil 1 , a mounting mechanism 2 , a locking mechanism 3 and a base 4 .

[0055] in:

[0056] Coil 1, used to support the mounting mechanism 2, the manipulator 6 on the mounting mechanism 2 and the base 4;

[0057] The mounting mechanism 2 is connected to the manipulator 6 via a connecting unit 21 provided thereon and is fixed on the coil 1;

[0058] The base 4 is fixed to the coil 1 by means of non-magnetic screws 5 and is used to cooperate with the locking mechanism 3 for quick assembly and disassembly;

[0059] The locking mechanism 3 is mounted on the base 4 and can lock and unlock the mounting mechanism 2 by rotating.

[0060] More specifically, in this embodiment:

[0061] As shown in FIG2 , the base 4 includes a coil connection unit 42 , a threaded through hole 43 on the coil connection unit 42 , and a connecting structure 41 . In this embodiment, the coil connection unit 42 is a wedge-shaped block, and the connecting structure 41 is a connecting groove structure.

[0062] The threaded through hole 43 is used to mount the coil connecting unit 42 on the coil 1 via the non-magnetic screw 5 and the threaded hole on the coil 1 .

[0063] The communication structure 41 is used to cooperate with the locking mechanism 3 to perform locking and unlocking.

[0064] As shown in FIG3 and FIG4 , the mounting mechanism 2 further includes a mounting plane 22 , a positioning unit 24 and a locking plane 23 . In this embodiment, the mounting plane 22 is a U-shaped plane, and the positioning unit 24 is a rectangular block.

[0065] The mounting plane 22 is in close contact with the coil 1 through the recessed plane 11 on the coil 1 , and the mounting mechanism 2 is restricted to a position where it can move except in the up and down directions through the positioning unit 24 and the positioning groove 12 on the coil 1 .

[0066] As shown in Figures 5, 6, and 7, the locking mechanism 3 includes a left groove support platform 35, a left locking platform 33, a base shaft 31, a right locking platform 34, a right groove support platform 36, and a handle 32. With respect to the installation direction of the mounting mechanism 2, the left groove support platform 35, the left locking platform 33, the right locking platform 34, the right groove support platform 36, and the handle 32 are arranged in order from left to right along the base shaft 31.

[0067] The base shaft 31 rotates within the interconnecting structure 41 on the base 4. When locking is required, the left and right locking platforms 33 and 34 can be rotated toward the top of the coil 1 by rotating the handle 32 to lock the mounting mechanism 2. At this time, the locking mechanism 3 can be translated to the left along the axis a of the base shaft 31 to confine the left and right groove support platforms 35 and 36 within the interconnecting structure 41 of the base 4, thus achieving the locking function.

[0068] When the manipulator 6 needs to be disassembled quickly, it only needs to translate the locking mechanism 3 to the right along the axis a of the base shaft 31 and rotate it toward the bottom of the coil 1. The left locking platform 33 and the right locking platform 34 will unlock the lock with the locking plane 23, realizing quick disassembly.

[0069] The present invention modularizes the mechanism between the manipulator support (mounting mechanism) and the coil, designing a slotted base and a base shaft with a platform. Locking and unlocking are achieved by rotating the base shaft, and securing is achieved by moving along the base shaft's axis. This invention addresses the prior art issues of the connection between the manipulator and coil in MRI-PHIFU systems, which are time-consuming, labor-intensive, inefficient, difficult to move, difficult to assemble, and inconvenient to disassemble. This allows for easy installation and disassembly of the manipulator and coil, significantly improving the efficiency of the device and ensuring the reliability of the MRI-PHIFU system during the treatment of tumors.

[0070] The above description of the embodiments is intended to facilitate understanding and use of the invention by those skilled in the art. It will be apparent that those skilled in the art can readily make various modifications to these embodiments and apply the general principles described herein to other embodiments without requiring inventive effort. Therefore, the present invention is not limited to the above-described embodiments. Improvements and modifications made by those skilled in the art based on the disclosure of the present invention, without departing from the scope of the present invention, should be within the scope of protection of the present invention.
