[0002] During surgery, a laparoscope is needed, such as for patients with gallstones or appendicitis. The laparoscope allows the location of lesions inside the body to be observed, facilitating surgical procedures.

[0003] Currently, these surgeries require multiple people to work together, including the surgeon, medical staff to support the endoscope, and medical staff to pass surgical instruments. Holding the endoscope for a long time is tiring, especially when the surgery is long and very strenuous. Therefore, how to replace manual labor with devices or instruments to reduce labor intensity is an urgent problem for technicians in this field. Utility Model Content

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0033] This invention provides a one-button electromagnetically controlled multi-joint follow-up locking and fixation device, which allows for one-button, single-hand operation of the endoscope position, facilitating convenient use by the surgeon and reducing labor intensity.

[0034] Figures 1-6 The schematic diagram shown is of one embodiment of the multi-joint follow-up locking and fixing device with one-button electromagnetic control according to this utility model. Please refer to the diagram. Figures 1-5 The multi-joint follow-up locking and fixing device with one-key electromagnetic control according to this embodiment includes a fixing frame 100, a joint assembly 200, a clamping mechanism 300 and an electromagnetic locking mechanism 400 in its main body.

[0035] The fixation frame 100 is clamped and fixed to the side of the operating table as a support for the whole. Specifically, in this embodiment, the fixation frame 100 includes a support rod 110, a U-shaped clamping block 120 disposed at the bottom end of the support rod 110, and a knob screw 130 extending from the bottom of the U-shaped clamping block 120 into its interior. In actual use, the U-shaped clamping block 120 is clamped to the side of the bed, and then the knob screw 130 is rotated until the knob screw 130 abuts against the bottom of the side of the bed. In this embodiment, the head end of the fixation frame 100 is provided with a first ball cage 140 for connecting to the joint assembly 200.

[0036] The joint components 200 are connected end to end to form a multi-joint structure that can rotate in all directions. The head end of the multi-joint structure is connected to the fixed frame 100 and can rotate in all directions relative to the fixed frame 100. In this embodiment, there are two joint components 200. The joint component 200 includes a connecting rod 210, a first ball head 220 disposed at the head end of the connecting rod 210, and a second ball cage 230 disposed at the tail end of the connecting rod 210. The first ball head 220 at the head end of the multi-joint structure is embedded in the first ball cage 140 and connected to the first ball cage 140 of the fixed frame 100.

[0037] The clamping mechanism 300 is connected to the tail end of the multi-joint structure and can rotate omnidirectionally relative to the multi-joint structure. Specifically, the clamping mechanism 300 includes a handle 310, a second ball head 320 disposed at the head end of the handle 310, and a clamp 330 disposed at the tail end of the handle 310. The second ball head 320 is embedded in the second ball cage 230 at the tail end of the multi-joint structure and is connected to the tail end of the multi-joint structure.

[0038] The electromagnetic locking mechanism 400 is embedded in the fixed frame 100 and the multi-joint structure respectively, and is used to control the locking of the fixed frame 100, the joint assembly 200 and the clamping mechanism 300. Specifically, the electromagnetic locking mechanism 400 includes a sleeve 410, an electromagnetic coil 420 disposed inside the sleeve 410, a reciprocating telescopic rod 430 extending from one end of the sleeve 410 into its interior, an arc-shaped cover 440 disposed at the end of the reciprocating telescopic rod 430 and adapted to the surfaces of the first ball head 220 and the second ball head 320, and an elastic member 450 sleeved on the reciprocating telescopic rod 430 and located between the sleeve 410 and the arc-shaped cover 440. The inner wall of the arc-shaped cover 440 is provided with a limiting protrusion H, and the surfaces of the first ball head 220 and the second ball head 320 are provided with limiting grooves L adapted to the limiting protrusion H. When the electromagnetic locking mechanism 400... When energized, the electromagnetic coil 420 generates an attractive force, causing the reciprocating telescopic rod 430 to move the arc-shaped cover 440 closer to the sleeve 410. The elastic component 450 is compressed, causing the limiting protrusion H on the arc-shaped cover 440 to separate from the limiting groove L, releasing the restriction on the first ball head 220 and the second ball head 320. The joint assembly 200 and the clamping mechanism 300 can rotate relative to the fixed frame 100. When the electromagnetic locking mechanism 400 is de-energized, the attractive force of the electromagnetic coil 420 disappears. Due to the rebound force of the elastic component 450, the reciprocating telescopic rod 430 moves the arc-shaped cover 440 away from the sleeve 410, causing the limiting protrusion H on the arc-shaped cover 440 to engage with the limiting groove L. The joint assembly 200 and the clamping mechanism 300 are locked in position relative to the fixed frame 100. Preferably, in this embodiment, the elastic component 450 is a spring.

[0039] In this embodiment, a control button is also provided on the clamping mechanism 300 and a rechargeable battery is provided inside the fixing frame 100. The control button is electrically connected to the rechargeable battery and the electromagnetic locking mechanism 400 respectively, and is used to control the circuit opening and closing of the electromagnetic locking mechanism 400.

[0040] Combination Figures 1-6 The specific usage process of the one-button electromagnetically controlled multi-joint follow-up locking and fixing device of this embodiment is as follows:

[0041] The one-button electromagnetically controlled multi-joint follow-up locking and fixation device of this embodiment is used as follows: First, the fixation frame 100 is clamped and fixed to the side of the operating table by the U-shaped clamp 120 and the knob screw 130 at the bottom, and the handle of the endoscope is clamped by the clamp 330 of the holding mechanism 300. Then, hold the handle 310 with one hand and press the control button. At this time, the electromagnetic locking mechanism 400 is energized, releasing the restriction on the joint component 200 and the clamping mechanism 300. Then, adjust the position of the joint component 200 and the clamping mechanism 300 as needed. After the position is adjusted, stop pressing the control button. At this time, the electromagnetic locking mechanism 400 is de-energized, and the position of the joint component 200 and the clamping mechanism 300 is restricted and fixed, thus fixing the endoscope.

[0042] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
