Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a medical device for orthopedic patients during surgery. Background Art

[0002] During orthopedic surgery, an external fixator is usually used to splice and fix the fractured limb of a patient. The inventor found during long-term surgeries that the external fixator is connected to the bone by steel pins or screws penetrating the skin. The pin track communicates with the outside world, and bacteria from the outside can easily infect the connection between the pin track and the skin, damaging the integrity of the skin. If the pin track is not properly cared for, such as not being regularly cleaned and disinfected, it is very easy to get infected, showing symptoms such as redness, swelling, pain, and exudation. In severe cases, complications such as osteomyelitis may occur. To prevent the pin track from infecting the human body, people will use clips to hold a disinfectant cotton swab dipped in iodophor to smear and wipe at the connection and around the pin track and the skin at regular intervals during daily care, cleaning the liquid overflowing from the damaged skin. Although this method greatly avoids wound infection, it requires frequent cleaning of the pin track and damaged skin, increasing the burden on already busy nursing staff. Moreover, some patients have fractures with bleeding, and a hemostatic device needs to be used to stop the bleeding before subsequent surgery. The operation is cumbersome, increasing the workload of medical staff and easily delaying the treatment time.

[0003] Therefore, we propose a medical device for orthopedic patients during surgery to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a medical device for orthopedic patients during surgery.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A medical device for orthopedic patients during surgery, including a plurality of connecting rods and two fixing rings. The plurality of connecting rods are arranged in an equidistant circular array between the two fixing rings. A plurality of mounting holes are circularly arranged on each fixing ring, and the mounting holes on the two fixing rings correspond to each other in sequence. A limb is placed between the two fixing rings, and a plurality of fixing pins are inserted through the limb. Both ends of each fixing pin are fixedly installed on the fixing ring through positioning bolts. The positioning bolts penetrate the mounting holes and are threadedly connected with matching positioning nuts;

[0006] Two adjusting components are symmetrically arranged on the side wall of the fixing ring, and each adjusting component is fixedly installed on the fixing ring through a mounting post.

[0007] As a further solution of the present invention: the adjustment assembly includes a mounting plate and a hemostatic plate, and the mounting plate and the hemostatic plate are fixed together by two limiting telescopic rods, a tightening screw is threadedly connected at the center of the mounting plate, a knob is fixedly installed at one end of the tightening screw, and a mounting sleeve is rotatably installed at the other end of the tightening screw, and the mounting sleeve is fixedly installed at the center of the side wall of the hemostatic plate.

[0008] As a further solution of the present invention: a liquid storage cavity is provided in the hemostatic plate, and two groups of disinfection components are symmetrically arranged at the bottom of the liquid storage cavity.

[0009] As a further solution of the present invention: each group of disinfection components includes two swinging floats, and the two swinging floats are rotatably installed at the bottom of the liquid storage chamber through a rotating shaft. The bottom of the liquid storage chamber is symmetrically provided with diversion channels on both sides of the swinging floats, and the diversion channels are L-shaped. The lower end of the diversion channel is provided with a drainage cotton column and communicated with the outside.

[0010] As a further solution of the present invention: a drainage tube is fixedly installed at the lower port of the diversion channel, the upper end of the drainage tube is inserted into the lower port of the diversion channel, the lower end of the drainage tube is provided with a Velcro, and a sterilizing cotton cloth is bonded to the middle part of the Velcro.

[0011] As a further solution of the present invention: an injection tube is fixedly mounted on the side wall of the hemostatic plate, and a cap is provided at the port of the injection tube.

[0012] As a further solution of the present invention: a sterilizing cotton is arranged on the side of the hemostatic plate facing away from the mounting plate;

[0013] As a further solution of the present invention, the vertical channel aperture of the guide channel is larger than the horizontal channel aperture;

[0014] As a further solution of the present invention, the swinging floating plate is T-shaped, and the swinging angle of the swinging floating plate is between 0-60°.

[0015] By adopting the above technical solution, compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The present invention adopts a fixing frame with an adjustment component. In addition to the stability advantage of the annular fixing frame, the fixing frame can also stop blood vessel bleeding in time, thereby alleviating the pain of the patient and the burden of the medical staff. The adjustment component has a simple structure, is easy to manufacture, and has a low cost.

[0017] 2. In the present invention, the two ends of the fixing needle are fixed on the fixing ring by the cooperation of the positioning nut and the positioning bolt. Since multiple holes need to be drilled on both sides of the bone fracture site, the adjusting assembly can ensure that the position of the limb and the fixing ring remains unchanged during each hole drilling and fixing needle installation process, making the hole drilling and fixing needle installation more accurate, efficient, and stable. Multiple elastic support blocks can also be placed between the fixing ring and the limb to facilitate timely adjustment of the tightness between the limb and the fixing ring, bringing comfort to the patient.

[0018] 3. In the present invention, disinfectant is injected into the hemostatic plate through the liquid injection tube. During the patient's rehabilitation exercise, the swinging floating plate swings left and right. The swinging of the swinging floating plate increases the pressure inside the liquid storage cavity, and the swinging direction of the swinging floating plate corresponds to the diversion channel, forcing the disinfectant in the liquid storage cavity to enter the diversion channel. After passing through the drainage cotton column at the lower end of the diversion channel, it enters the drainage tube and finally flows out from the lower end of the drainage tube to disinfect the damaged area at the connection between the fixing needle and the limb, eliminating the need for nursing staff to disinfect the needle track regularly and reducing the workload of the nursing staff.

[0019] 4. The disinfection component set in the present invention has the advantages of simple structure, convenient installation, and low cost. Most importantly, through daily rehabilitation training or exercise, the swinging floating plate is prompted to swing, and the disinfectant in the liquid storage cavity flows out, thus completing the precise disinfection of the needle track, replacing the traditional manual nursing disinfection method, saving time and effort.

[0020] 5. In the present invention, the aperture of the vertical channel of the diversion channel is larger than that of the horizontal channel. When the liquid enters the diversion channel, it will first enter the horizontal channel through the vertical channel. Since the aperture of the vertical channel is larger than that of the horizontal channel, the liquid has a certain driving force when entering the drainage tube. When it discharges from the lower end of the drainage tube, the liquid collides with the fixing needle and scatters, increasing the disinfection area of the skin. Due to the volatile characteristic of the iodophor liquid, the iodophor liquid flowing out of the iodophor drainage tube gradually volatilizes under the action of body temperature after cleaning the wound, taking away the heat on the skin surface and preventing the limb skin under the gauze from generating pustules.

[0021] Other advantages, objectives, and features of the present invention will be described to some extent in the subsequent specification, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be learned from the practice of the present invention.

Detailed implementation manners

[0035] The following further describes the detailed implementation manners of the present invention with reference to the accompanying drawings. It should be noted here that the description of these implementation manners is used to help understand the present invention, but does not constitute a limitation to the present invention.

[0036] In addition, the technical features involved in the various implementation manners of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] Embodiment 1, please refer to the appendixFigures 1 - 5 , which is the first embodiment of the present invention. A medical device for orthopedic patients provided in this embodiment uses an adjustable component 7 of a circular external fixator to promptly stop bleeding at the fracture site of the patient's limb 8, and positions and joins the fracture site of the patient's limb 8 through the cooperation of the adjustable component 7, fixing pins 6, fixing rings 9, and connecting rods 1, greatly improving the surgical efficiency and reducing the patient's pain. It includes a plurality of connecting rods 1 and two fixing rings 9. The plurality of connecting rods 1 are arranged in an equidistant circular array between the two fixing rings 9. A plurality of mounting holes 2 are circularly arranged on each fixing ring 9, and the mounting holes 2 on the two fixing rings 9 correspond to each other in sequence. A limb 8 is placed between the two fixing rings 9, and a plurality of fixing pins 6 are inserted through the limb 8. Both ends of each fixing pin 6 are fixedly installed on the fixing ring 9 through positioning bolts 4. The positioning bolts 4 penetrate the mounting holes 2 and are threadedly connected with matching positioning nuts 3. This fixator can be formed by connecting a plurality of circular fixing rings 9 through connecting rods 1 and fixing pins 6, surrounding the limb 8 for one week, and completely enclosing the limb 8 within the fixator. Through the fixing pins 6 in multiple directions and the circular structure, it can provide all-round fixing force, enabling the fracture ends to be better stabilized in all directions, especially suitable for complex fracture types such as severely comminuted fractures, open fractures, and fractures with bone defects;

[0038] Specifically, two adjustable components 7 are symmetrically arranged on the side wall of the fixing ring 9. Each adjustable component 7 is fixedly installed on the fixing ring 9 through a mounting post 5. The adjustable component 7 includes a mounting plate 703 and a hemostatic plate 704. The mounting plate 703 and the hemostatic plate 704 are fixedly installed together through two limit telescopic rods 702. The limit telescopic rods 702 are used to prevent the hemostatic plate 704 from shifting during movement. A tightening screw 701 is threadedly connected to the center of the mounting plate 703. One end of the tightening screw 701 is fixedly installed with a knob 709, and the other end of the tightening screw 701 is rotatably installed with a mounting sleeve 706. The mounting sleeve 706 is fixedly installed at the center of the side wall of the hemostatic plate 704. A disinfected cotton 707 is arranged on the side of the hemostatic plate 704 facing away from the mounting plate 703. When the patient enters the operating room, the patient's limb 8 is inserted into this circular fixator, and then the knobs 709 on both sides of the limb 8 are tightened, so that the tightening screw 701 pushes the hemostatic plate 704 against the epidermis of the limb 8, pressing the blood vessels under the epidermis and avoiding continuous bleeding of the blood vessels, resulting in blood loss and causing the patient to go into shock. Among them, the thread pitch of the tightening screw 701 is 1 mm, and the number of thread turns is 200 turns.

[0039] Further illustrate the working mode and advantages of this medical device in combination with the prior art:

[0040] The fixation structures used for orthopedic surgery patients in the existing technologies are roughly divided into two types. One is a single-arm external fixator composed of a single-sided fixation pin 6 and a connecting rod 1, which is generally fixed on one side of the limb 8. The structure is relatively simple. During the treatment process, if fine adjustment of the fracture site is required, the operation is relatively convenient, and the tightness or angle of the external fixator can be adjusted at any time according to the fracture healing situation. However, its stability is insufficient. Especially when bearing large external forces, such as during weight-bearing or strenuous activities, situations such as loosening of the fixation pin 6 and fracture displacement are likely to occur. The other is a ring-shaped external fixator similar to the structure of the present invention, which has higher stability than the single-arm external fixator. However, at the beginning of the operation, additional hemostatic equipment is required to stop bleeding of the limb 8, which is extremely inconvenient for emergency patients;

[0041] Returning to the present invention, first insert the patient's limb 8 into the ring-shaped fixator, and then tighten the knobs 709 on both sides of the limb 8, so that the tightening screw 701 pushes the hemostatic plate 704 against the epidermis of the limb 8, pressing the blood vessels under the epidermis to prevent continuous bleeding of the blood vessels and blood loss, which may cause shock to the patient. And after fixing the limb 8 through the adjusting component 7, medical staff can start the operation at the bone fracture site and drill holes on both sides of the bone fracture site, pass the fixation pin 6 through the drilled holes, and fix both ends of the fixation pin 6 on the fixing ring 9 through the cooperation of the positioning nut 3 and the positioning bolt 4. Since multiple holes need to be drilled on both sides of the bone fracture site, therefore, the adjusting component 7 can ensure that the position of the limb 8 and the fixing ring 9 remains unchanged during each drilling and installation of the fixation pin 6. Multiple elastic support blocks can also be placed between the fixing ring 9 and the limb 8 to facilitate timely adjustment of the tightness between the limb 8 and the fixing ring 9, bringing comfort to the patient.

[0042] In the basic logic and concept expressed above, the medical device for orthopedic patients provided by the present invention is significantly different from the existing technologies, manifested as:

[0043] Firstly, the present invention adopts the adjusting component 7, so that the medical device in the present invention not only has the stability advantages of the ring-shaped fixator but also can stop blood vessel bleeding in time, reducing the pain of the patient. The adjusting component 7 has a simple structure, low cost, and is easy to manufacture;

[0044] Secondly, both ends of the fixation pin 6 are fixed on the fixing ring 9 through the cooperation of the positioning nut 3 and the positioning bolt 4. Since multiple holes need to be drilled on both sides of the bone fracture site, therefore, the adjusting component 7 can ensure that the position of the limb 8 and the fixing ring 9 remains unchanged during each drilling and installation of the fixation pin 6. It has high stability. Multiple elastic support blocks are also placed between the fixing ring 9 and the limb 8 to facilitate timely adjustment of the tightness between the limb 8 and the fixing ring 9, bringing comfort to the patient.

[0045] For other contents of the adjusting component 7, please refer to Embodiment 2.

[0046] In summary, by using the adjustment component 7, the present invention can not only adjust to adapt to the size differences of different patients' limbs 8 and stop bleeding in a timely manner, but also ensure that during each hole punching and installation of the fixing needle 6 in subsequent surgeries, the position of the limb 8 and the fixing ring 9 remains unchanged, with high stability, improving the accuracy of hole punching and installation of the fixing needle 6, and greatly reducing the pain of the patient.

[0047] Example 2. Please refer to the attached Figures 6 - 12 , which is the second embodiment of the present invention. The adjustment component 7 provided in this embodiment includes a disinfection component 10, which has the effect of automatically cleaning the needle track, reducing the pain of the patient, and improving the bone recovery speed of the patient. It includes a hemostatic plate 704, in which a liquid storage cavity 708 is opened. At the bottom of the liquid storage cavity 708, two groups of disinfection components 10 are symmetrically arranged;

[0048] Each group of disinfection components 10 includes two swinging floating plates 1006. The two swinging floating plates 1006 are rotatably installed at the bottom of the liquid storage cavity 708 through a rotating shaft 1005. At both sides of the swinging floating plate 1006 at the bottom of the liquid storage cavity 708, diversion channels 1007 are symmetrically opened. The diversion channels 1007 are L-shaped. At the lower end of the diversion channel 1007, a drainage cotton column 1004 is provided and communicates with the outside. At the lower port of the diversion channel 1007, a drainage tube 1001 is fixedly installed. An inner seal ring for sealing is embedded at the connection between the diversion channel 1007 and the drainage tube 1001. The upper end of the drainage tube 1001 is inserted into the lower port of the diversion channel 1007. At the lower end of the drainage tube 1001, a magic tape 1002 is provided. Both ends of the magic tape 1002 are coated with a waterproof adhesive, and a sterilizing cotton cloth 1003 is bonded to the middle part of the magic tape 1002;

[0049] After the fixing frame is installed on the limb 8, disinfectant is injected into the hemostatic plate 704 through the liquid injection tube 705. Then, one end of the disinfection component 10 is installed at the lower end of the corresponding diversion channel 1007, and the other end is adhered to the skin surface through the magic tape 1002, so that the drainage tube 1001 is aligned with the connection between the fixing needle 6 and the skin of the limb 8. During the patient's rehabilitation exercise, the swinging floating plate 1006 swings left and right. By the swinging of the swinging floating plate 1006, the pressure inside the liquid storage cavity 708 is increased, and the swinging direction of the swinging floating plate 1006 corresponds to the diversion channel 1007, forcing the disinfectant in the liquid storage cavity 708 to enter the diversion channel 1007. After passing through the drainage cotton column 1004 at the lower end of the diversion channel 1007, it enters the drainage tube 1001, and finally flows out from the lower end of the drainage tube 1001 to disinfect the damaged part at the connection between the fixing needle 6 and the limb 8. There is no need for the nursing staff to disinfect the needle track regularly, reducing the workload of the nursing staff. And the flowing disinfectant can also take away the overflowing body fluid and be absorbed by the sterilizing gauze wrapped around the surrounding limb 8, avoiding secondary infection;

[0050] In particular, since the iodine tincture liquid is volatile, the iodine tincture liquid flowing out of the iodine tincture drainage tube 1001 gradually evaporates under the action of body temperature after cleaning the wound, taking away the heat from the skin surface, thereby preventing abscesses from forming on the skin of the limb 8 under the gauze;

[0051] An injection tube 705 is fixedly mounted on the side wall of the hemostatic plate 704, and a cap is provided at the end of the injection tube 705, so that disinfectant or other liquid medicine can be injected into the hemostatic plate 704 through the injection tube 705;

[0052] A sterilizing cotton 707 is arranged on the side of the hemostatic plate 704 away from the mounting plate 703. The sterilizing cotton 707 has a good bactericidal effect to prevent bacteria from being generated between the hemostatic plate 704 and the limb 8;

[0053] The aperture of the vertical channel of the diversion channel 1007 is larger than that of the transverse channel. When the liquid enters the diversion channel 1007, it will first enter the transverse channel through the vertical channel. Since the aperture of the vertical channel is larger than that of the transverse channel, the flow radius is reduced and the flow rate is accelerated when the flow rate remains unchanged, so that the liquid has a certain power when entering the drainage tube 1001. When discharged from the lower end of the drainage tube 1001, the liquid collides with the fixed needle 6 and disperses, thereby increasing the disinfection area of ​​the skin;

[0054] The swing float 1006 is T-shaped, and the top part of the swing float 1006 has the largest mass and is suspended in the disinfectant. The swing float 1006 swings left and right at an angle between 0 and 60 degrees. When the patient does rehabilitation exercises or activities, the top of the swing float 1006 will swing left and right under the action of gravity and inertia, increasing the internal pressure of the liquid storage chamber 708, so that the disinfectant overflows outward through the diversion channel 1007.

[0055] The liquid storage cavity 708 is filled with disinfectant, which is iodine tincture or alcohol. The iodine tincture can disinfect the connection between the fixing needle 6 and the skin of the limb 8, and can take away the heat on the skin surface when volatilizing to avoid the formation of abscesses.

[0056] The disinfection assembly 10 provided by the present invention is significantly different from the prior art in that:

[0057] First, after the operation in the prior art, medical nursing staff need to disinfect the needle track regularly, which increases the work pressure on the nursing staff. In the present invention, disinfectant liquid is injected into the hemostatic plate 704 through the liquid injection tube 705. During the patient's rehabilitation exercise, the swing float plate 1006 swings left and right. The swing of the swing float plate 1006 increases the pressure inside the liquid storage cavity 708, and the swing direction of the swing float plate 1006 corresponds to the diversion channel 1007, forcing the disinfectant liquid in the liquid storage cavity 708 to enter the diversion channel 1007. After passing through the drainage cotton column 1004 at the lower end of the diversion channel 1007, it enters the drainage tube 1001 and finally flows out from the lower end of the drainage tube 1001 to disinfect the damaged part at the connection between the fixing needle 6 and the limb 8, eliminating the need for nursing staff to disinfect the needle track regularly and reducing the work burden of the nursing staff;

[0058] Second, the disinfection component 10 provided in the present invention has the advantages of simple structure, convenient installation and low cost. Most importantly, through daily rehabilitation training or exercise, the swing float plate 1006 is urged to swing, and the disinfectant liquid in the liquid storage cavity 708 flows out, thus completing the precise disinfection of the needle track, replacing the traditional manual nursing disinfection method, saving time and effort;

[0059] Third, in the present invention, the vertical channel aperture of the diversion channel 1007 is larger than the horizontal channel aperture. When the liquid enters the diversion channel 1007, it will first enter the horizontal channel through the vertical channel. Since the vertical channel aperture is larger than the horizontal channel aperture, the liquid has a certain driving force when entering the drainage tube 1001. When discharging from the lower end of the drainage tube 1001, the liquid collides and scatters with the fixing needle 6, increasing the disinfection area of the skin. Since the iodophor liquid has the characteristic of being volatile, after the iodophor liquid flowing out of the iodophor drainage tube 1001 finishes cleaning the wound, under the action of body temperature, it gradually volatilizes and takes away the heat on the skin surface, preventing the skin of the limb 8 under the gauze from generating pustules.

[0060] The remaining structures of this embodiment are the same as those of the first embodiment.

[0061] In summary, in this embodiment, when the patient performs rehabilitation exercise, the rehabilitation exercise is basically that the patient tries to walk and exercise or walks with the help of rehabilitation exercise equipment, which prompts the swing float plate 1006 in the hemostatic plate 704 to start swinging left and right. The swing of the swing float plate 1006 increases the pressure inside the liquid storage cavity 708, causing the disinfectant liquid in the liquid storage cavity 708 to enter the drainage tube 1001 along the diversion channel 1007. Under the simultaneous action of gravity and pressure, the disinfectant liquid flows to the connection between the fixing needle 6 and the skin of the limb 8 for disinfection;

[0062] During the movement of the patient's body, metabolism will accelerate, and body fluid will flow out at the needle track. The disinfectant can just carry away the body fluid and be absorbed by the surrounding gauze, eliminating the need for caregivers to perform regular care, thus reducing their work pressure. Moreover, both iodophor and alcohol used as disinfectants are volatile liquids. Under the action of body temperature, they gradually volatilize, taking away the heat at the wound and preventing the formation of pustules, thereby increasing the patient's recovery speed.

[0063] By effectively combining the hemostatic plate 704 with the patient's activities, this medical device solves the problem in the prior art that "in order to prevent the needle track from infecting the human body, people need to frequently clean the needle track and the damaged skin, adding a burden to the already busy caregivers".
