Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly, to an orthopedic shoulder arthroscopic surgery traction device. Background Art

[0002] Orthopedic surgery, also known as orthopaedic surgery, is a surgical form in which orthopedic surgeons use surgical or non-surgical methods to treat injuries or various health problems of the musculoskeletal system. Among the many types of orthopedic surgeries, the most common ones are as follows: knee arthroscopy and meniscectomy, shoulder arthroscopy and decompression, carpal tunnel release, knee arthroscopy and chondroplasty, brace implant removal, knee arthroscopy and anterior cruciate ligament reconstruction, knee replacement, femoral neck fracture repair, humeral fracture repair, and hip replacement.

[0003] With the development of minimally invasive surgery technology, shoulder arthroscopic surgery has gradually become an important means for treating shoulder diseases. An arthroscope is a rod-shaped optical instrument with a diameter of about 5 mm for observing the internal structure of a joint, and it is an endoscope used for diagnosing and treating joint diseases. The arthroscope is equipped with a lens at the end of a thin tube. When the thin tube is inserted into the joint, the internal structure of the joint will be displayed on the monitor. The success of a shoulder arthroscopic surgery is highly related to the patient's body position. The body position requires that the distal part of the affected limb needs to be suspended, abducted about 45 degrees, and flexed between 10 degrees and 15 degrees. The upper limb needs to be tractioned by a traction frame and suspended, so as to ensure the smooth progress of the surgery.

[0004] Clinically, the patient's arm and hand are wrapped with gauze, and then pulled by a traction frame through a rope. In this way, the bundling operation is cumbersome, and the arm will receive a large force to complete the traction, which is likely to cause secondary injury to the patient. The traction adjustment is inconvenient, and the distal part of the affected limb is completely wrapped in the gauze, resulting in poor comfort.

[0005] The patent with the publication number of CN116585137A discloses an orthopedic shoulder arthroscopic surgery traction device, which includes a base, a support rod, a lifting rod, and an adjustment disk. One side of the top surface of the base is vertically welded with a support rod, the top end of the support rod is slidably embedded with a lifting rod, the lifting rod has an "L" shaped structure, the top end of the lifting rod is welded with an adjustment disk, the adjustment disk remains horizontal, a slider is slidably connected to the bottom surface of the adjustment disk, an adjustment bolt is threadedly connected between the adjustment disk and the slider, a connecting plate is fixedly welded to the bottom end of the slider, an adjustment handle is slidably embedded in the side surface of the connecting plate, and a traction disk is rotatably connected to the bottom end of the connecting plate. When this invention is in use, traction fixation is carried out by means of air pressure, which is not only firmly fixed, but also saves the fixation time. At the same time, it can be fixed and tractioned at any angle as needed, is convenient to use, and the traction angle is more in line with the surgical requirements, reducing the surgical difficulty.

[0006] Although the traction device in the above-mentioned prior art can achieve traction at any angle, it pulls after completely covering the arm and hand during the traction process.

[0027] Embodiment

[0028] The inventors found through research that when the patient's arm and hand are wrapped with gauze and then pulled by a traction frame with a rope, the bundling operation is cumbersome, and the arm will receive a relatively large force to complete the traction, which is likely to cause secondary injuries to the patient. The traction adjustment is inconvenient, and the distal part of the affected limb is completely wrapped in the gauze, resulting in poor comfort. Therefore, this application provides an orthopedic shoulder arthroscopic surgery traction device that is simple to operate, convenient to use, and improves the surgical field of view and efficiency.

[0029] In the embodiments of this application, please refer to Figure 1-14As shown in the figure, it is a schematic structural diagram of an orthopedic shoulder arthroscopic surgery traction device provided by an embodiment of the present application. An orthopedic shoulder arthroscopic surgery traction device includes a shoulder traction frame 100, and further includes: a affected limb fixator connected to the traction end of the shoulder traction frame 100; the affected limb fixator includes a finger fixation structure 400, a wrist fixation structure 300, and an arm fixation structure 500, which are used to fix the finger, wrist, and arm respectively.

[0030] When the present invention is used in shoulder arthroscopic surgery, the present invention provides a stable supporting force through the shoulder traction frame 100, and separately fixes the finger, wrist, and arm at the distal end of the affected limb through the affected limb fixator, forming an open fixation, improving the use comfort, avoiding the discomfort of patients caused by excessive traction weight or inconvenient adjustment of traditional devices, eliminating the cumbersome operation of binding, and reducing the space occupied by fixation, expanding the surgical field of view, facilitating the surgeon's operation, improving the surgical efficiency and patient safety, increasing the success rate of the surgery, effectively preventing the traction injury of the brachial plexus nerve, and reducing the incidence of postoperative complications. The orthopedic shoulder arthroscopic surgery traction device of the present invention is easy to operate, has high safety, and a wide range of applications.

[0031] In the embodiment of the present application, please refer to Figure 2 , Figure 2 is a schematic structural diagram of the shoulder traction frame provided by the embodiment of the present application. The shoulder traction frame 100 is an auxiliary instrument designed specifically for the lateral position surgery of shoulder arthroscope, and is also used for the treatment of diseases such as shoulder dislocation. By pulling the arm, it assists in completing shoulder surgery or helps the shoulder restore its normal anatomical relationship. One end is a fixed end, which is stably connected to the bedside rail of the operation through a fixator to ensure the stability and safety of the traction frame during the operation and provide reliable support for the operation; and the fixed end is provided with vertical and horizontal telescopic structures, and thus the vertical height and horizontal length of the traction device can be adjusted; and through the cooperation of the ball hinge and the telescopic structure, the angle of the traction device can be adjusted. In this way, it can be applicable to the traction of patients in different positions. The other end is a traction end, which has an electric telescopic function. The shoulder traction frame 100 is a common prior art, which can be realized by those skilled in the art and will not be elaborated here.

[0032] In the embodiment of the present application, please refer to Figure 3 , Figure 3 is a schematic structural diagram of the fixing frame provided by the embodiment of the present application. A claw-shaped fixing frame 200 is connected to the traction end of the shoulder traction frame 100.

[0033] A fixing frame 200 is welded or clamped on the electric push rod 101 vertically arranged at the traction end of the shoulder traction frame 100. The fixing frame 200 is in the shape of four claws facing downwards, and the electric push rod 101 passes through the middle of the fixing frame 200.

[0034] It should be noted that the electric push rod 101 is at least a three-stage type. The fixed frame 200 is connected to the second stage, and the affected limb fixator is connected to the third stage. In this way, the height of the overall fixed frame 200 and the affected limb fixator can be adjusted through the first stage. The fixed frame 200 on the second stage can remain stationary, and the third stage can be telescoped within the affected limb fixator.

[0035] In the embodiment of the present application, please refer to Figure 4 and Figure 5 , Figure 4 which is a schematic structural diagram of the wrist fixation structure provided by the embodiment of the present application; Figure 5 which is a schematic structural diagram of the wrist fixation structure provided by the embodiment of the present application. The wrist fixation structure 300 includes: two groups of push rods 301, which are respectively fixed to the inner side of the fixed frame 200; two groups of push plates 302, which are respectively fixed to the outer side of the traction end of the shoulder joint traction frame 100, and the positions correspond to the positions of the upper parts of the push rods 301 one by one; a wrist clamping assembly, which is arranged at the end of the push rod 301 away from the push plate 302; wherein, the traction end of the shoulder joint traction frame 100 drives the push plate 302 to move, the push plate 302 squeezes the upper part of the push rod 301 to move outward, and at the same time the lower part of the push rod 301 moves inward, and the wrist clamping assembly moves accordingly, so that the wrist clamping assembly squeezes and fixes the wrist.

[0036] The push rod 301 is in an obtuse angle shape and is integrally formed. The obtuse angles face each other inward. The middle of the obtuse angle is hinged to the inner side of the fixed frame 200, and one push rod 301 is hinged to each branch of the fixed frame 200.

[0037] The cross-section of the push plate 302 is in an L shape. Its bottom is used for welding with the outer side of the third stage of the electric push rod 101. The side of the push plate 302 is an isosceles trapezoid and is inclined, with the lower part facing inward and the upper part facing outward. The two groups of push plates 302 are arranged around the electric push rod 101 at the same height, enclosing an isosceles trapezoid inverted bucket shape. The upper part of the push plate 302 can form an outward thrust on the upper part of the push rod 301, and the push plate 302 corresponds to the push rod 301 one by one.

[0038] Further, the wrist clamping assembly includes a telescopic rod 303 and a skin-friendly layer 304 wrapped outside it. The telescopic rod 303 is connected to the lower part of the push rod 301.

[0039] The telescopic rod 303 adopts a double-headed telescopic rod 303, which is a common existing technology and can be realized by those skilled in the art, so it will not be elaborated here. The telescopic rod 303 is horizontally placed, and the middle part of it is welded or clamped to the lower end part of the push rod 301. The telescopic rod 303 can be adjusted according to the thickness of the wrists of different patients to adapt to individual differences.

[0040] To ensure the comfort of the patient and avoid affecting the telescopic movement of the telescopic rod 303, a skin-friendly layer 304 is adhesively bonded to the outer layer of the middle part of the telescopic rod 303. The skin-friendly layer 304 can be made of materials such as sponge or silica gel. This is common prior art and can be implemented by those skilled in the art, so it will not be elaborated here.

[0041] To guide the push rod 301 and prevent it from shifting during deflection, a telescopic guide rod 305 is welded or clamped between the outer side of the upper part of the push rod 301 and the inner side of the fixed rod. This is common prior art and can be implemented by those skilled in the art, so it will not be elaborated here.

[0042] In the embodiment of the present application, please refer to Figure 6 and Figure 7 , Figure 6 which is a schematic structural diagram of the finger fixing structure provided by the embodiment of the present application; Figure 7 is a cross-sectional view of the finger fixing structure provided by the embodiment of the present application. The finger fixing structure 400 includes: a sleeve 401 with a cavity inside and a piston 402 disposed therein. The pulling end of the shoulder joint traction frame 100 is connected to the piston 402; a palm ball 403, which is a hollow spherical shape and is fixedly connected to the lower part of the sleeve 401. The inside of the palm ball 403 is a cavity and is communicated with the inside of the sleeve 401; a plurality of finger clamping components are circumferentially arranged outside the palm ball 403. The finger clamping components are communicated with the inside of the palm ball 403, and the intervals between the finger clamping components are used for placing fingers; wherein, the pulling end of the shoulder joint traction frame 100 drives the piston 402 to slide along the inner wall of the sleeve 401, and the piston 402 slides to squeeze the gas in the sleeve 401 and the palm ball 403, so that the gas enters the finger clamping components and drives the finger clamping components to clamp and fix the fingers.

[0043] The sleeve 401 is in a hollow cylindrical shape, and its lower side outside is fixed to the fixed frame 200 through a connecting rod 404 by welding or clamping. The electric push rod 101 passes through the upper part of the sleeve 401 and is welded to the upper part of the piston 402.

[0044] Specifically, the outer surface of the palm ball 403 is printed with grasping five-finger prints. In the present application, finger clamping components are provided on both the left and right sides of each finger print.

[0045] Furthermore, the finger clamping assembly includes: an arc-shaped block 405 fixedly connected to the outside of the palm ball 403, and the inside of the arc-shaped block 405 is in communication with the inside of the palm ball 403; a corrugated pipe 406, one end of which is connected to the arc-shaped block 405, and the inside of the corrugated pipe 406 is in communication with the inside of the arc-shaped block 405; a magnet 407 connected to the end of the corrugated pipe 406 away from the arc-shaped block 405, and the opposite magnets 407 are of opposite magnetic poles; wherein, gas enters the corrugated pipe 406 through the arc-shaped block 405, driving the corrugated pipe 406 to extend, and at the same time the magnet 407 moves accordingly, and the opposite magnets 407 clamp and fix the fingers under the action of magnetic attraction.

[0046] The corrugated pipe 406 is an elastic sensitive element with axial corrugations. One end of it is fixedly connected to the palm ball 403, and the other end is bonded with a magnet 407. This is a common prior art and can be realized by those skilled in the art, so it will not be elaborated here.

[0047] The mutually attracting magnets 407 generally refer to objects with magnetism and mutually attracting magnetic poles. Commonly, they are permanent magnets 407, such as bar magnets, horseshoe magnets, etc. A permanent magnet 407 is an object that can maintain magnetism for a long time. The atomic magnetic moments inside it are arranged neatly, thus showing magnetism externally. According to the properties of magnetic poles, like magnetic poles repel each other, and opposite magnetic poles attract each other. When two permanent magnets 407 are close to each other, if their magnetic poles are opposite magnetic poles (for example, one is an N pole and the other is an S pole), they will attract each other. This is common prior art and can be realized by those skilled in the art, so it will not be elaborated here.

[0048] Magnets 407 are provided on both the left and right sides of each finger print, and they are of opposite magnetic poles.

[0049] Optionally, in order to improve the comfort of patients, a silica gel layer is adhesively coated outside the magnet 407, which can be a thin silica gel pad. On the one hand, it provides buffering for the patient's skin, and on the other hand, it ensures the normal magnetism of the magnet 407 and can provide sufficient clamping force. This is common prior art and can be realized by those skilled in the art, so it will not be elaborated here.

[0050] In the embodiment of the present application, please refer to Figure 8 , Figure 8 is a schematic structural diagram of the arm fixing structure provided by the embodiment of the present application. The arm fixing structure 500 is in the shape of a soft plate and is arranged at the lower part of the fixing frame 200. The upper part of the arm fixing structure 500 is fixedly connected to the lower part of the fixing frame 200.

[0051] When the fingers and the wrist are both clamped and fixed, the arm fixing structure 500 is completely attached to the forearm, and the arm fixing structure 500 and the forearm are wound and tied tightly with a gauze.

[0052] Application process Now, in combination with the embodiments, the specific application process of an orthopedic shoulder arthroscopic surgery traction device in shoulder arthroscopic surgery will be specifically described.

[0053] Due to the special anatomical structure of the shoulder joint, patients with shoulder arthritis, biceps brachii rupture, osteoarthritis, etc. usually need to adopt the lateral position during shoulder arthroscopic surgery. To obtain a good surgical field of view and facilitate surgical operation, an upper limb traction device is often required to maintain the abduction design requirements of the affected limb. Shoulder arthroscopic surgery is suitable for the surgical treatment of joint loose bodies, biceps brachii rupture, osteoarthritis, etc.

[0054] During shoulder arthroscopic surgery: Before the surgery, the patient will undergo a series of examinations, including blood tests, electrocardiograms, etc., to ensure that the physical condition is suitable for the surgery. At the same time, the doctor will explain the surgical process in detail, as well as the possible risks and complications.

[0055] The surgery usually uses general anesthesia or local anesthesia plus intravenous sedation. The patient generally takes the lateral position, and the upper limb on the surgical side is abducted to facilitate surgical operation.

[0056] Then, after adjusting the affected limb fixator to the appropriate position, let the patient grasp the palm ball 403 along the fingerprint. Then start the electric push rod 101. The electric push rod 101 drives the piston 402 in the sleeve 401 to slide and squeeze the gas in the sleeve 401 and the palm ball 403, so that the gas enters the corrugated pipe 406 through the arc-shaped block 405, driving the corrugated pipe 406 to extend. At the same time, the magnet 407 moves accordingly, and the opposite magnets 407 clamp and fix the fingers under the action of magnetic attraction.

[0057] The electric push rod 101 also drives the push plate 302 to move. The push plate 302 squeezes the upper part of the push rod 301 to rotate outward, and at the same time the lower part of the push rod 301 rotates inward. Then, through the push rod 301, the telescopic rod 303 and its skin-friendly layer 304 wrapped outside clamp and fix the patient's wrist.

[0058] At the same time, the arm fixing structure 500 is completely attached to the forearm, and the arm fixing structure 500 and the forearm are wound and tied tightly with gauze. Finally, the clamping and fixing of the patient's hand, wrist and forearm are realized.

[0059] After the fixation and traction are completed, the doctor makes several small incisions of 5 - 10 mm around the shoulder joint, and inserts the arthroscope and surgical instruments through these incisions for diagnosis and treatment.

[0060] After the surgery, the small incisions will be sutured, and the patient needs to carry out rehabilitation training under the guidance of the doctor to promote the recovery of joint function.

[0061] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
