Description

Technical Field

[0001] This invention belongs to the field of surgical aids technology, specifically referring to a minimally invasive interventional device for cerebrovascular surgery. Background Technology

[0002] Cerebrovascular surgery is a relatively precise procedure, requiring a high degree of precision in the control of surgical instruments. Currently, doctors mostly use handheld instruments, but this is extremely difficult. Doctors often need to undergo a long period of professional training, and the actual operation is also highly dependent on the doctor's personal skills and condition. Based on clinical trials and daily observations, it is difficult for the human hand to perform precise operations in a completely free three-dimensional space, and it is prone to trembling. If a limit is added to one direction, such as simply supporting one point of the tool on the table, the precise positional control of the tool becomes much easier. Based on this phenomenon, this solution proposes a new minimally invasive surgical intervention device. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a minimally invasive interventional device for cerebrovascular surgery. The metal contact one and the metal contact two can transmit driving power and electrical signals. After the two are connected, the movement of the surgical tools can be controlled through the touch screen. The magnetic tool holder and the magnetic base are designed with a magnetic adsorption quick-release structure, which can facilitate the replacement of tools during the operation. Moreover, different tools are operated and controlled through the same control handle and touch screen, which is also simpler for doctors.

[0004] The technical solution adopted by the present invention is as follows: The present invention proposes a minimally invasive interventional device for cerebrovascular surgery, including a universal support assembly, a quick-release control assembly, a detachable assembly, a handle assembly, a ring support assembly, and an adjustable support leg assembly. The universal support assembly is slidably disposed in the ring support assembly. The quick-release control assembly and the handle assembly are respectively disposed below and above the universal support assembly. The detachable assembly is detachably disposed below the quick-release control assembly. The ring support assembly is rotatably disposed on the adjustable support leg assembly.

[0005] Furthermore, the universal support assembly includes a sliding ball head and a hinge seat. The sliding ball head is slidably disposed in the annular support assembly. A cantilever rod is provided on one side of the sliding ball head. A hinge portion is provided on the cantilever rod. The hinge seat is rotatably disposed on the hinge portion.

[0006] By combining the sliding ball joint and the open annular slide, the position of the surgical tools can be flexibly adjusted, and the position and angle of the surgical tools can be flexibly and freely adjusted within a certain range by utilizing the universal adjustment feature of the ball joint.

[0007] Furthermore, this design provides an axial limit for surgical tools in a completely free three-dimensional space, which greatly reduces the difficulty of precise adjustment.

[0008] Furthermore, the quick-release control assembly includes a lower connecting rod, a rotating mechanism, and a magnetic base. The lower connecting rod is located below the hinge seat, and the rotating mechanism is located between the lower connecting rod and the magnetic base.

[0009] Preferably, the bottom of the magnetic base is provided with a metal contact one, and the detachable component includes a magnetic tool holder, which is provided with a metal contact two corresponding to the metal contact one. The magnetic tool holder and the magnetic base are connected by magnetic attraction.

[0010] Preferably, the surgical tool is fixed to a magnetic tool holder, the outline of which corresponds to the groove outline of the magnetic base.

[0011] Metal contact one and metal contact two can transmit driving power and electrical signals. After the two are connected, the movement of the surgical tools can be controlled through the touch screen. The magnetic tool holder and the magnetic base are designed with a magnetic adsorption quick-release structure, which can facilitate the replacement of tools during the operation. Moreover, different tools are all operated and controlled through the same control handle and touch screen, which is also simpler for doctors.

[0012] Furthermore, the handle assembly includes an upper connecting rod and a control handle. The upper connecting rod is located above the hinge seat, and the control handle is located on the upper connecting rod. The control handle is equipped with a touch screen. When the magnetic base and the magnetic tool seat are connected through metal contact one and metal contact two, the surgical tool can be controlled through the touch screen.

[0013] Furthermore, the annular support assembly includes an annular bracket and an ear-shaped bracket. The annular bracket consists of an open annular slide, an outer ring, and a support rod. The sliding ball head is slidably disposed in the open annular slide.

[0014] Preferably, the ear-shaped bracket consists of a support link and a pitch support, and the ear-shaped bracket is symmetrically arranged outside the annular bracket, with the outer ring and the support link being fixedly connected.

[0015] Furthermore, the adjustable outrigger assembly includes outriggers and a lifting frame, the lifting frame being slidably mounted on an annular support, the top of the lifting frame being provided with a supporting connecting rod, and the pitch support being rotatably mounted on a hinge shaft.

[0016] The ring support assembly and adjustable outrigger assembly allow for flexible adjustment and locking of the installation position of the open ring slide before surgery, thus adapting to the operational needs of different patients and different surgical sites.

[0017] Preferably, the surgical tool can be an electric surgical tool such as a scalpel, forceps, scissors, or tweezers.

[0018] The beneficial effects achieved by the present invention using the above structure are as follows: (1) By combining the sliding ball head and the open annular slide, the position of the surgical tool can be flexibly adjusted, and the position and angle of the surgical tool can be flexibly and freely adjusted within a certain range by taking advantage of the universal adjustment feature of the ball joint.

[0019] (2) Moreover, this scheme provides an axial limit for the surgical tool in a completely free three-dimensional space, which greatly reduces the difficulty of precise adjustment.

[0020] (3) The metal contact one and the metal contact two can transmit driving power and electrical signals. After the two are connected, the movement of the surgical tool can be controlled through the touch screen. The magnetic tool holder and the magnetic base are designed with a magnetic adsorption quick-release structure, which can facilitate the replacement of tools during the operation. Moreover, different tools are operated and controlled through the same control handle and touch screen, which is simpler for doctors.

[0021] (4) The installation position of the open annular slide can be flexibly adjusted and locked before surgery by the ring support assembly and adjustable outrigger assembly, so as to adapt to the operation needs of different patients and different surgical sites. Attached Figure Description

[0029] By using the sliding ball joint 11 and the open annular slide 511, the position of the surgical tool 32 can be flexibly adjusted, and the position and angle of the surgical tool 32 can be flexibly and freely adjusted within a certain range by utilizing the universal adjustment feature of the ball joint.

[0030] Moreover, this design provides an axial limit for the surgical tool 32 in a completely free three-dimensional space, which greatly reduces the difficulty of precise adjustment.

[0031] The quick-release control assembly 2 includes a lower connecting rod 21, a rotating mechanism 22, and a magnetic base 23. The lower connecting rod 21 is located below the hinge seat 12, and the rotating mechanism 22 is located between the lower connecting rod 21 and the magnetic base 23.

[0033] The surgical tool 32 is fixed to the magnetic tool holder 31, and the outline of the magnetic tool holder 31 corresponds to the groove outline of the magnetic base 23.

[0034] Metal contact 231 and metal contact 311 can transmit driving power and electrical signals. After they are connected, the movement of the surgical tool 32 can be controlled through the touch screen 421. The magnetic tool holder 31 and the magnetic base 23 are designed with a magnetic adsorption quick-release structure, which can facilitate the replacement of tools during the operation.
