Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a 3D device for the lower limbs after interventional treatment for liver cancer. Background Technology

[0002] A search of existing Chinese patent document CN221932301U reveals a lower limb immobilization and care device after interventional treatment for liver cancer. The device includes a base plate, a thigh fixation band, a knee fixation band, a calf fixation band, a foot fixation component, and a monitor. The base plate has a thigh placement section, a knee placement section, a calf placement section, and a foot placement section arranged sequentially. Flexible thigh fixation bands are provided on both sides of the thigh placement section. The foot fixation component is arc-shaped, with both ends connecting to the sides of the foot placement section, forming a foot insertion hole between the foot fixation component and the foot placement section. The monitor is mounted on the convex surface of the foot fixation component. This device solves the technical problems of traditional lower limb immobilization and care devices after interventional treatment for liver cancer, which involve localized binding of the patient's leg, hindering blood flow and causing discomfort, and are unable to monitor the patient's foot skin temperature and pulse.

[0003] Currently, most devices on the market for immobilizing liver cancer patients after interventional surgery are traction devices. These devices typically need to be fixed in a specific position on the bed to immobilize the patient. However, this method of immobilization often results in patients being unable to move their limbs freely after surgery, significantly reducing their comfort. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a 3D device for the lower limbs after interventional treatment for liver cancer, which aims to solve the technical problem of limb fixation after interventional treatment.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a 3D device for the lower limb after interventional treatment for liver cancer, comprising an upper fixation component and a lower fixation component. The upper and lower fixation components are connected and fixed by a bolt assembly, which corresponds to the bolt fixing holes on both sides of the upper and lower fixation components. A sieve hole is provided on one side surface of both the upper and lower fixation components, and an infusion hole is provided on one side end surface of both the upper and lower fixation components. Velcro strap perforations are provided on both sides of the upper fixation component.

[0007] As a further description of the above technical solution:

[0008] Both the upper and lower fixing components are made of transparent, malleable plates and are semi-circular in shape. The bolt assembly includes bolts and nuts.

[0009] As a further description of the above technical solution:

[0010] The upper and lower fixing components have multiple sets of screen holes on their surfaces, arranged in an arc shape in each row. The screen hole radius is 3.75 mm, and the spacing between each row is 30 mm.

[0011] As a further description of the above technical solution:

[0012] The Velcro strap has two perforations on each side, arranged vertically to the two ends of the upper fastener.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, by overcoming the limitations of current braking devices, it can be directly fixed to the position of the arterial sheath, providing patients with multiple lying angle options after surgery, allowing them to enjoy greater comfort post-operatively. At the same time, it can effectively maintain the braking effect, ensuring the stability and recovery of the surgical site, and effectively improving the overall efficiency of use.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] In the attached diagram, all identical reference numerals refer to the same components.

[0023] Example 1

[0024] Reference Figure 1-4 One embodiment of this utility model is a 3D device for the lower limb after interventional treatment for liver cancer, comprising an upper fixation member 1 and a lower fixation member 2. The upper fixation member 1 and the lower fixation member 2 are connected and fixed by a bolt assembly 3. The bolt assembly 3 corresponds to the bolt fixing holes 4 at the ends of the two side surfaces of the upper fixation member 1 and the lower fixation member 2. A sieve hole 5 is provided on one side surface of both the upper fixation member 1 and the lower fixation member 2. An infusion hole 6 is provided at the end of one side surface of both the upper fixation member 1 and the lower fixation member 2. Velcro strap through holes 7 are provided on both side surfaces of the upper fixation member 1.

[0025] Both the upper fixing member 1 and the lower fixing member 2 are made of transparent and malleable plates, and both are semi-circular arc-shaped. The bolt assembly 3 includes bolts and nuts.

[0026] The upper fixing part 1 and the lower fixing part 2 have multiple sets of screen holes 5, arranged in an arc shape in each row. The radius of the screen holes 5 is 3.75mm and the spacing between each row is 30mm.

[0027] The Velcro strap perforations 7 are set in pairs on each side, arranged vertically to the two ends of the upper fastener 1.

[0028] Specifically, its structure consists of an upper fixing component 1, a lower fixing component 2, a bolt assembly 3, bolt fixing holes 4, a sieve hole 5, an infusion port 6, and a Velcro strap perforation 7, forming a 3D lower limb device for liver cancer interventional procedures. This device can meet the needs of different patients, employing reusable materials and structural design to ensure its stability and reliability during repeated use. It enhances the patient's treatment experience, effectively improves their satisfaction, and thus optimizes the overall postoperative recovery process. The main body of device D is composed of an upper fixing part 1 and a lower fixing part 2. The whole is made of a transparent and malleable plate. The densely distributed sieve holes 5 can increase air permeability and improve patient comfort. At the same time, it is combined with the infusion port 6 to facilitate the nurse to check the puncture site. The handle at the junction of the upper fixing part 1 and the lower fixing part 2 is formed by the bolt assembly 3. The angle of the device can be rotated to adapt to the patient's needs. The external part of the arterial catheter can be exposed through the sieve holes 5 to facilitate drug infusion. The lower fixing part 2 is placed on the thigh to effectively immobilize the lower limb and keep it stable within the required range.

[0029] Working Principle: The lower limb 3D device testing method after liver cancer interventional surgery uses a 3D printer to produce a test model, and the specific size of the model is adjusted according to clinical practice. The upper fixation component 1 and the lower fixation component 2 are connected through bolt fixing holes 4, and fixed in conjunction with bolt assembly 3. Bolt assembly 3 can be rotated to adjust the angle to suit the patient. The upper fixation component 1 is close to the groin and anterior superior iliac spine, controlling the angle at which the patient's upper body is raised. The lower fixation component 2 is close to the thigh, controlling the angle at which the patient's lower body is raised. An infusion port 6 allows the connection of the infusion end, facilitating observation of the puncture site. This port can be wiped clean and reused. A Velcro strap control device is used to adjust the tightness of the strap to fit the thigh through the Velcro strap perforation 7.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
