Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and more specifically, to a medical rheumatology and immunology internal medicine detection auxiliary equipment and a use method thereof. Background Art

[0002] In the field of rheumatology and immunology, accurate detection is a key link in disease diagnosis, condition assessment and treatment plan formulation; traditional detection methods have many limitations in joint detection, such as difficulty in locating the joint bursa, resulting in poor accuracy of puncture and other operations, affecting the reliability of test results. The development of new detection auxiliary equipment is of great significance to improving the diagnosis and treatment of rheumatic and immunological diseases.

[0003] In knee joint fixation, splints are generally fixed on both sides and around the legs by bandages, mainly relying on external force to limit leg movement; sandbags are placed under the thighs and calves, using their weight to compress the legs to maintain posture. Compared with mechanical clamps, conventional clamping and fixation methods cannot quickly and conveniently switch between the two states of slight flexion and extension according to puncture requirements and patient joint conditions. The splint and sandbag fixation methods are difficult to adjust, and the slight flexion and extension state of the legs cannot be changed after fixation. It is often necessary to readjust the position of the splint and the number of sandbags, which is a cumbersome operation and difficult to achieve precise angle adjustment.

[0004] During joint puncture, the joint bulge needs to be pressed because the bulge is usually where joint cavity effusion or lesions are more obvious. However, doctors usually press the joint based on their vision and experience to feel the tension and elasticity of the joint and the patient's pain response, so as to further understand the degree and state of the joint lesions. However, the joint anatomy and morphology of different patients are different. For example, obese patients have thicker subcutaneous fat, which makes the surface landmarks of the joint bulge unclear, and it is difficult to accurately judge its position only by relying on the doctor's vision and experience. For patients with joint deformities, the normal morphology of the joint changes, increasing the difficulty of accurate positioning. Compared with lighting the joint surface bulge, the doctor's vision and experience judgment are affected in dim light or complex environments. This is a relatively subjective observation method with certain limitations.

[0005] In view of this, we propose a medical rheumatology and immunology internal medicine detection auxiliary equipment and a method of using the same. Summary of the invention

[0006] The purpose of the present invention is to provide a medical rheumatology and immunology internal medicine detection auxiliary equipment and its use method, so as to solve the technical problems that the joint bending adjustment is difficult after the leg is fixed, and the joint bulging cysts of special patients are difficult to detect.

[0020] The present invention also provides a method for using the above-mentioned medical rheumatology and immunology internal medicine detection auxiliary device, comprising the following steps:

[0021] S1. Medical history collection: Ask the patient in detail about the onset and development of symptoms such as joint pain, swelling and deformity, so as to fully understand the patient's overall health status and provide a basis for judging the nature of the joint disease;

[0022] S2, joint puncture: first disinfect the knee joint leg, then cover the patient's leg with a drape, with the joint in the hole of the drape;

[0023] S2.1. Leg fixation: The two arc-shaped plates are axially moved by the latch pin to open the device, and the patient places the legs inside the two arc-shaped frames, and then the arc-shaped plates are rotated to restore, wherein the locking bolt passes through the locking hole, and the locking bolt is twisted to fix the arc-shaped plates and the arc-shaped frames. Then, through the external control system, gas is filled inside the airbag, and the airbag expands to fix the patient's legs inside the two arc-shaped frames;

[0024] S2.2, knee joint bending adjustment: after the leg is fixed, the first motor is operated through the external circuit mechanism, and the first motor drives the screw rod to move the right support frame to the left side. At the same time, when the distance between the two support frames is reduced, the rubber rod is squeezed and deformed. Several rubber rods are arc-shaped, and the rubber rods are gathered at fixed points to form an arc, which contacts the bottom of the patient's knee joint, and several curved surfaces of the rubber rods can provide support for the thigh and calf. In this process, the degree of knee joint bending can be adjusted by adjusting the distance between the two support frames. At the same time, when the rubber rod is bent, several abutments contact each other to support the bent rubber rod. When the rubber rod is in a straight line, several abutments are arranged in a linear array and movably contact with the metal rope to support the straight rubber rod, so as to prevent the rubber rod from fatigue and collapse.

[0025] S2.3, joint capsule positioning: manually move the positioning frame to the top of the drape, and after confirming the position of the positioning frame, one set of diagonally distributed first telescopic rods is fixed in the retaining groove by a toggle plate to fix the positioning frame, and the other set of diagonally distributed first telescopic rods moves with the positioning frame to achieve a telescopic effect. After positioning, illuminate the joint surface with an irradiation lamp, confirm the joint capsule on the joint by observing the light, determine the needle insertion position, use a puncture needle to enter the joint cavity, and draw out the joint effusion;

[0026] S2.4. Joint effusion squeezing: When extracting the joint, the first torsion spring applies force to the bending rod so that the ball contacts the joint surface, and through the elastic rope, the ball can change shape according to the shape of the joint surface, and then the second motor is operated through the external circuit mechanism to drive the first gear, and then through the gear transmission, the inner gear ring rotates, driving the two movable rods to move towards or in the opposite direction, causing the ball to roll on the joint surface and squeeze out the effusion in the joint capsule. The whole ball moves at an angle, and further squeezes out the viscous liquid in the joint capsule, preventing the ball from moving on the joint surface in the same line, which causes excessive pressure on the joint cyst and affects the effect of joint puncture.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The present invention can adjust the distance between the two support frames and further adjust the leg bending by setting an adjustment component through threaded drive, and squeeze the rubber rod through the two support frames to make the rubber rod arc-shaped, thereby performing a semi-wrapped support effect on the joint, thigh and calf, and has solved the problem that the joint bending is difficult to adjust after the leg is fixed. Then, through the irradiation component, a parallel motion structure is adopted to realize the three-axial movement of the positioning frame, and the position of the positioning frame and the hole of the drape can be quickly adjusted. At the same time, the joint surface is irradiated by an irradiation lamp, and the reflection and transmission of light on the joint surface are observed to judge the position, size and boundary of the joint capsule, and the position confirmation of the joint bulge of special patients is solved. The present invention integrates the information of joint bending adjustment, judgment of joint capsule position and flexible extrusion of the joint surface to squeeze out the internal fluid, which is conducive to improving the applicability of the device.

[0029] 2. The present invention sets a rubber rod and drives the screw rod through the first motor to move the right support frame to the left side, and then adjusts it according to the patient's leg length to make it reach the most comfortable position. At the same time, by reducing the distance between the two support frames, the rubber rod is deformed into an arc shape by the extrusion force, and a plurality of rubber rods are distributed in an arc array, so that the vertices of the arc-shaped rubber rods gather together, and then provide an arc-shaped support for the patient's knee joint. The rubber rod is made of rubber material, and its own elastic characteristics further improve the comfort. The present invention can expose the joint cyst site more obliquely by adjusting the bending degree of the patient's leg joint, which is convenient for doctors to accurately find the best injection point. At the same time, it simulates the joint conditions of patients in different activity states, which helps doctors to monitor and operate more realistically.

[0030] 3. The present invention realizes the three-axial movement of the positioning frame by arranging a stop structure on two diagonally distributed first telescopic rods. The position of the positioning frame can be manually adjusted so that it can be conveniently and quickly positioned above the joint. At the same time, the positioning frame is fixed by the stop structure to provide sufficient space for the joint puncture needle and a stable puncture area. When the joint capsule is pressed in the puncture needle, the irradiation lamp illuminates the joint surface, and the position, size and boundary of the joint capsule are confirmed by observing the reflection and transmission of light on the joint surface. Compared with the doctor's visual and experience judgment, this method is more accurate.

[0031] 4. The present invention applies a force to the bending rod through the first torsion spring, so that a plurality of balls fit the patient's joint, and through the elastic rope, the plurality of balls are deformed according to the shape of the patient's joint surface, so that each ball contacts the joint surface, and then the two movable rods are driven by the inner gear ring to move toward each other, so that the two groups of balls roll on the joint surface while the two groups of balls make reciprocating tilting motions at the same time, so that the accumulated fluid in the joint capsule is gathered toward the needle hole. Compared with the doctor's manual pressure, the accumulated fluid cannot be extracted by one-handed operation. The present invention gathers and extracts the accumulated fluid in the joint cyst by using flexible contact, which can avoid the contact between hard instruments and the joint capsule and damage to the surrounding tissues.

[0032] 5. The present invention provides a bending structure so that when the leg is bent, a number of stops contact each other, and can support the rubber rod during bending to prevent the rubber rod from fatigue and collapse during support. When the rubber rod is in a straight line, a number of stops contact the metal rope to support the straight rubber rod to prevent the rubber rod from collapsing and affecting the leg support effect.

[0052] like Figure 3 As shown, the adjustment component 3 includes two first motors 31, and the two first motors 31 are fixedly connected to one side of the left support frame 1 in a symmetrical structure. The output shafts of the two first motors 31 are fixedly connected to the transmission rods 32, and the transmission rods 32 pass through the right support frame 1.

When the rubber rod 33 is in a straight line, a plurality of stoppers 331 contact the metal rope 332, to support the straight rubber rod 33, to prevent the rubber rod 33 from collapsing and affecting the leg support effect.

[0061] Embodiment 3,

[0062] A method for using a medical rheumatology and immunology internal medicine detection auxiliary device comprises the following steps:

[0063] S1. Medical history collection: Ask the patient in detail about the onset and development of symptoms such as joint pain, swelling and deformity, so as to fully understand the patient's overall health status and provide a basis for judging the nature of the joint disease;

[0064] S2, joint puncture: first disinfect the knee joint leg, then cover the patient's leg with a drape, with the joint in the hole of the drape;

[0065] S2.1. Leg fixation: The two arc-shaped plates 23 are axially moved by the latch pin to open the device, and the patient places the legs inside the two arc-shaped frames 21, and then the arc-shaped plates 23 are rotated to restore, wherein the locking bolt 24 passes through the locking hole 25, and the locking bolt 24 is twisted to fix the arc-shaped plates 23 and the arc-shaped frames 21.

[0066] S2.2, knee joint bending adjustment: after the leg is fixed, the first motor 31 is operated through the external circuit mechanism, and the first motor 31 drives the screw rod 321 to move the right support frame 1 to the left. At the same time, when the distance between the two support frames 1 is reduced, the rubber rod 33 is squeezed and deformed. Several rubber rods 33 are arc-shaped, and the rubber rods 33 are gathered at fixed points to form an arc, contacting the bottom of the patient's knee joint, and the curved surfaces of several rubber rods 33 can provide support for the thigh and calf. In this process, the degree of knee joint bending can be adjusted by adjusting the distance between the two support frames 1.
