Description

Technical Field

[0001] The invention relates to the technical field of body position fixing frames, and in particular to a multifunctional body position fixing frame for puncture surgery. Background Art

[0002] In the modern medical field, puncture surgery is a common and important diagnostic and treatment method, widely used in the treatment of diseases in multiple parts of the chest, abdomen, etc. Taking thoracentesis as an example, it plays a key role in the diagnosis and treatment of diseases such as pleural effusion.

[0003] There are many limitations to the traditional method of fixing the body position during thoracentesis surgery. In the early days, medical staff mostly relied on simple beds or ordinary chairs to place patients, and lacked precise fixing devices designed specifically for puncture needs. On the one hand, the patient's position is difficult to control accurately, and different patients have different body shapes. Without effective limiters, it is difficult to ensure that the patient is in the best and consistent position for each puncture. For example, when puncturing pleural effusion, ideally the patient needs to maintain a specific posture so that the effusion is in a position in the chest cavity that is convenient for extraction. Ordinary chairs cannot meet this precise position requirement, which often leads to inaccurate positioning of the puncture point, increasing the difficulty and risk of puncture.

[0004] On the other hand, the stability during the operation is poor. The puncture operation requires the patient to remain as still as possible for a period of time to prevent the puncture needle from shifting and causing complications. However, conventional support facilities cannot resist the patient's unconscious body twisting due to tension and discomfort, as well as inadvertent collision interference from the outside world. Once the patient's position changes, the puncture needle may deviate from the predetermined path, which will not only affect the puncture effect, but may also damage important organs and blood vessels in the chest cavity, endangering the patient's life and health.

[0005] Furthermore, with the development of medical technology, puncture surgery has become more and more sophisticated. For example, ultrasound-guided thoracentesis has more stringent requirements for body position fixation. Traditional fixation methods are difficult to perfectly cooperate with advanced auxiliary examination technologies (such as ultrasound examination), and cannot ensure that the patient's body position matches the puncture path determined by the ultrasound image throughout the puncture process. It is not conducive to the doctor's real-time and accurate operation of the puncture needle, reducing the efficiency and success rate of the operation.

[0006] In summary, the existing means of body position fixation for puncture surgery can no longer meet the growing medical needs. There is an urgent need for a body position fixation frame that can overcome the above-mentioned defects, is multifunctional, precise and stable, so as to ensure the smooth progress of puncture surgery and improve medical quality and patient safety. Summary of the invention

[0007] The present invention provides a multifunctional body position fixing frame for puncture surgery, which solves the problem that the fixing frame in the prior art is inconvenient to adjust and has inaccurate positioning.

[0008] The technical solution of the present invention is as follows: A multifunctional body position fixing frame for puncture surgery, comprising: Frame; A seat, slidably disposed on the frame, and used for a patient to sit on; A leaning member, swingably arranged on the frame, the leaning member is located on one side of the sitting member, the sitting member slides close to or away from the leaning member, and the leaning member is used for the patient to lean on; The seat is used for sitting upright or sitting backward. When sitting upright, the patient faces away from the backrest member, and when sitting backward, the patient faces toward the backrest member. The limiting member is used to limit the position of the seat member after the seat member slides.

[0009] As a further technical solution, it also includes: A supporting member is arranged on the supporting member in a lifting manner and is used for supporting the head or chin of the patient.

[0010] As a further technical solution, The frame is provided with positioning engraved lines, and a plurality of positioning engraved lines are evenly arranged along the sliding direction of the seat.

[0011] As a further technical solution, The seat is provided with a positioning seat groove, the width of which gradually increases from the middle to both sides, and the positioning seat groove is used to limit the position of the patient on the seat.

[0012] As a further technical solution, the leaning member includes: A main rod body, one end of which is swingably arranged on the frame body, and the other end of which is lifted and lowered with the support; The middle part of the arc-shaped leaning rod is rotatably arranged on the main rod body. A plurality of the arc-shaped leaning rods are evenly distributed along the main rod body. After the arc-shaped leaning rod is rotated, its arc-shaped opening faces toward or away from the seat.

[0013] As a further technical solution, the leaning member further includes: There are two side rods, and the two ends of the arc-shaped leaning rod are respectively hinged to the side walls of the two side rods.

[0014] As a further technical solution, the leaning member further includes: A soft pad, the middle part of which is arranged on the main rod body.

[0015] As a further technical solution, The middle part of the soft pad is detachably arranged on the main rod body through Velcro, magnet, rope or double-sided adhesive.

[0016] As a further technical solution, The frame body is provided with a strip hole, the strip hole is located below the seat, and the seat is provided with a fastening screw hole; The limiting member is a fastening screw, which is slidably arranged in the strip hole, one end of which is threadedly connected to the fastening screw hole, and the fastening screw locks or cancels the locking of the seat member after being rotated.

[0017] As a further technical solution, it also includes: The universal wheel is arranged at the bottom of the frame.

[0018] The working principle and beneficial effects of the present invention are: In the present invention, the frame body serves as the basic supporting structure of the entire fixing frame, and has sufficient strength and stability to bear the patient's weight and withstand the external force impact that may be generated during the puncture operation, ensuring that the fixing frame as a whole will not shake or deform, and providing a safe and reliable posture support platform for the patient.

[0019] The sliding setting of the seat breaks the limitations of traditional fixed position devices. In the scenario of pleural effusion puncture, when it is necessary to select the puncture point from a larger area of ​​the patient's back, such as for different degrees of pleural effusion distribution, or considering the doctor's operating habits and required operating space, the seat can be slid outward to increase the distance between it and the support, so that the doctor can flexibly operate the puncture instrument. The upright and reverse sitting modes fully take into account various puncture needs. Conventional pleural effusion puncture mostly adopts upright sitting, with the patient's back to the support; once the patient encounters special circumstances and it is inconvenient to perform the puncture operation from the back, the reverse sitting mode allows the patient to face the support, and the doctor can smoothly perform precise puncture from the chest.

[0020] In addition, the sliding setting of the seat has many benefits: on the one hand, the sliding seat can be adjusted to a suitable position according to different patients; on the other hand, it can adapt to the needs of sitting upright and sitting backward, and keep the seat in a suitable position in different postures; finally, the seat can be adjusted to a suitable position according to actual conditions, which is convenient for the doctor's operation.

[0021] The limiter can lock the seat after it slides to a suitable position to prevent instability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention.

In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0026] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0028] like Figures 1 to 5As shown, the present invention proposes a multifunctional body position fixing frame for puncture surgery, comprising: a frame 1; a seat 2 slidably arranged on the frame 1, and the seat 2 is used for a patient to sit; a leaning member 3 is swingably arranged on the frame 1, and the leaning member 3 is located on one side of the seat 2, and the seat 2 slides close to or away from the leaning member 3, and the leaning member 3 is used for the patient to lean on; the seat 2 can be sat upright or reversed, when sitting on the seat 2 upright, the patient has his back to the leaning member 3, and when sitting on the seat 2 reversely, the patient faces the leaning member 3; a limiting member 4 is used to limit the position of the seat 2 after it slides.

[0029] In this embodiment, the frame 1 serves as the basic supporting structure of the entire fixing frame, and has sufficient strength and stability to bear the patient's weight and withstand the external force impact that may be generated during the puncture operation, ensuring that the fixing frame as a whole will not shake or deform, providing the patient with a safe and reliable posture support platform.

[0030] The sliding setting of the seat 2 breaks the limitations of traditional fixed position devices. In the pleural effusion puncture scenario, when it is necessary to select the puncture point from a larger area of ​​the patient's back, for example, for different degrees of pleural effusion distribution, or considering the doctor's operating habits and required operating space, the seat 2 can be slid outward to increase the distance with the backrest 3, so that the doctor can flexibly operate the puncture instrument. The upright and reverse sitting modes fully take into account various puncture needs. Conventional pleural effusion puncture mostly adopts upright sitting, with the patient facing away from the backrest 3; once the patient encounters special circumstances and it is inconvenient to perform the puncture operation from the back, the reverse sitting mode allows the patient to face the backrest 3, and the doctor can smoothly perform precise puncture from the chest.

[0031] In addition, the sliding setting of the seat 2 has many advantages: on the one hand, the sliding seat 2 can be adjusted to a suitable position according to different patients; on the other hand, it can adapt to the needs of sitting upright and sitting backward, and keep the seat 2 in a suitable position in different postures; finally, the seat 2 can be adjusted to a suitable position according to actual conditions, which is convenient for the doctor's operation.

[0032] The limiting member 4 can be locked after the seat member 2 slides to a suitable position to prevent instability.

[0033] Furthermore, it also includes a supporting member 5, which is arranged on the leaning member 3 in a lifting manner, and the supporting member 5 is used to support the patient's head or chin.

[0034] In this embodiment, in some more complex, delicate and time-consuming puncture operations, patients often need to maintain a fixed head posture for a long time, which can easily cause neck muscle fatigue and soreness, and then cause the head to shake unconsciously, seriously affecting the accuracy of puncture. The lifting function of the support 5 perfectly solves this problem. Medical staff can accurately adjust the height of the support 5 according to the height and body shape of the patient to ensure that it properly supports the patient's head or chin. When the patient sits on the seat 2, the support 5 supports the head; when sitting on the seat 2, the support 5 supports the chin. For example, for tall patients, the support 5 is appropriately raised to provide comfortable support for their heads and avoid neck pressure caused by looking up for a long time; and for petite patients, the height of the support 5 is lowered to prevent excessive compression of the chin. In this way, the patient's neck muscles can be relaxed, and the desired posture can be stably maintained for a long time, which greatly improves the patient's comfort, so that they can maintain a good cooperation state throughout the operation process, providing a strong guarantee for the success of the puncture.

[0035] Further, refer to Figure 2 As shown, the frame 1 has positioning engraved lines 11 , and a plurality of positioning engraved lines 11 are evenly arranged along the sliding direction of the seat 2 .

[0036] In this embodiment, the positioning mark 11 acts like a precise ruler.

[0037] On the one hand, it provides a clear reference for the position of the seat 2 when the medical staff operates the fixing frame. In clinical practice, time is life, especially when facing emergency puncture surgery, it is very important to adjust the position of the seat 2 quickly and accurately. Medical staff only need to glance at the positioning scale line 11, and they can quickly slide the seat 2 to the corresponding scale line position based on past experience and the current patient's specific puncture needs, which greatly saves the time of repeatedly debugging the position of the seat 2 and significantly improves the efficiency of puncture preparation. At the same time, each adjustment can accurately refer to the scale line to ensure the repeatability and accuracy of the distance between the seat 2 and the backrest 3, so that each puncture operation position is standardized and normalized, effectively avoiding the deviation of the puncture result caused by the position error, and ensuring the stability and reliability of medical quality.

[0038] On the other hand, an information database can be established for the patients, that is, an information database for position adjustment. When the patients have corresponding puncture needs or need to undergo multiple operations, the position of the seat 2 can be adjusted in advance for each patient according to the scale information of the corresponding retained positioning mark line 11, so as to facilitate and quickly perform the operation, while improving the patient's experience and reducing the tension caused by the long time of adjusting the seat 2.

[0039] Further, refer to Figure 1 As shown, the seat 2 has a positioning seat groove 21 , the width of which gradually increases from the middle to both sides, and the positioning seat groove 21 is used to limit the position of the patient on the seat 2 .

[0040] In this embodiment, the design of the positioning seat groove 21 fully conforms to the ergonomic principle and the width of the positioning seat groove 21 gradually increases from the middle to the sides, that is, a symmetrical design, which satisfies the patient to maintain the same sitting feeling whether sitting upright or sitting backward, and its shape closely fits the human buttocks curve. When the patient sits down, the buttocks can be naturally and comfortably embedded in the groove, and the patient's body is accurately limited from the horizontal dimension, and the positioning line 11 can better meet the accuracy of the sitting posture.

[0041] Furthermore, the leaning member 3 includes a main rod body 31, one end of which is swingably set on the frame body 1, and the other end of which is lifted and lowered with a supporting member 5; an arc-shaped leaning rod 32, the middle part of which is rotatably set on the main rod body 31, and there are several arc-shaped leaning rods 32 evenly distributed along the main rod body 31. After the arc-shaped leaning rod 32 rotates, its arc-shaped opening faces toward or away from the seat member 2.

[0042] In this embodiment, the swing setting at one end of the main rod body 31 and the sliding function of the seat 2 complement each other, and together provide the patient with a multi-dimensional leaning angle adjustment capability. In thoracocentesis surgery, different puncture sites have different requirements for the patient's body inclination. For example, when the puncture point is located at a higher position in the chest cavity and the patient's upper body needs to lean back moderately, the main rod body 31 can be swung to increase the angle between it and the plane of the seat 2, and guide the patient to adjust the body position naturally; on the contrary, if the puncture point is close to the lower part of the chest cavity, the angle can be appropriately reduced to allow the patient to lean forward. The rotatable design of the arc leaning rod 32 is even more exquisite. When the patient needs to sit upright, the arc leaning rod 32 is rotated so that its arc opening direction faces the patient, which can make the patient's back support more comfortable, so that the patient can relax his body and facilitate the puncture operation; when the patient needs to sit backward, facing the arc leaning rod 32, the arc leaning rod 32 is rotated at this time so that its opening direction faces away from the patient, so that the patient will be more comfortable and convenient for long-term surgical operations.

[0043] Furthermore, the leaning member 3 further includes two side rods 33 , and the two ends of the arc-shaped leaning rod 32 are hinged to the side walls of the two side rods 33 respectively.

[0044] In this embodiment, the addition of the side rod 33 is like putting a layer of "solid armor" on the leaning member 3, which greatly enhances its structural stability. During the patient's leaning process, the body weight will be transmitted through the arc-shaped leaning rod 32. If there is only a single support of the arc-shaped leaning rod 32, it is easy to have a risk of excessive force on a single point, causing its deformation and displacement, affecting the patient's leaning experience, and even endangering the safety of the puncture operation. The two side rods 33 are hinged at both ends of the arc-shaped leaning rod 32, which cleverly disperses the force and evenly distributes the patient's body pressure to multiple support points, ensuring that the arc-shaped leaning rod 32 always maintains a stable shape, and the patient always leans on a reliable support surface. At the same time, the hinged structure enables the side rod 33 to have adaptive adjustment capabilities. When the arc-shaped leaning rod 32 rotates to adjust the angle to adapt to the different body position requirements of the patient, the side rod 33 can rotate flexibly accordingly, without affecting the flexible adjustment function of the leaning member 3 as a whole, and continuously providing stable and reliable support for the patient.

[0045] Reference Figure 5 As shown, the arc-shaped leaning rod 32 is divided into a middle rod 321, an arc-shaped rod 322 and an edge rod 323 from the middle to the two sides. The middle rod 321 and the edge rod 323 are both cylindrical, and the two ends of the arc-shaped rod 322 are respectively connected to one end of the middle rod 321 and one end of the edge rod 323. The middle rod 321 is parallel to the edge rod 323, and the free end of the edge rod 323 is hinged to the side rod 33, so that the arc-shaped opening of the arc-shaped leaning rod 32 is facing toward or away from the seat 2 after the arc-shaped leaning rod 32 is rotated, and the cushion 34 is adapted to each other to meet the two states before and after the rotation. There is a socket on the middle rod 321, and the position of the arc-shaped leaning rod 32 is fixed by the plug rod that passes through the main rod body 31 and is inserted into the socket, so that it can be stably supported in two states.

[0046] Furthermore, the leaning member 3 further includes a cushion 34 , and the middle portion of the cushion 34 is arranged on the main rod body 31 .

[0047] In this embodiment, the cushion 34 may seem simple, but it plays an important role in improving the comfort of the patient. During a long puncture operation, the patient's back is in contact with hard objects for a long time, which can easily cause a sense of oppression and discomfort in the back. This discomfort will gradually increase over time, causing the patient to be irritable and difficult to maintain a stable puncture position, which indirectly affects the smooth progress of the puncture operation. The cushion 34 directly contacts the patient's back, and its soft material effectively buffers the pressure of the hard object, as if a layer of "comfortable cushion" is laid on the patient's back, making the patient feel more comfortable. Especially for patients who need to maintain the same leaning posture for a long time, the cushion 34 can significantly reduce back discomfort, stabilize their emotions, better cooperate with the entire operation process, and lay a good foundation for the patient's state for the success of the puncture.

[0048] In addition, the middle part of the cushion 34 is arranged on the main rod body 31, and the other parts are not connected, so it can adapt to the rotation of the arc-shaped leaning rod 32 in two states, which is very clever.

[0049] Velcro is provided on the left and right sides of the cushion 34 near the arc-shaped leaning rod 32, and Velcro is also provided on the left and right sides of the arc-shaped leaning rod 32. Figure 2 As shown, when the arc-shaped opening of the arc-shaped leaning rod 32 is facing away from the side of the seat 2, by bending the left and right sides of the cushion 34, the cushion 34 is fitted to the arc-shaped leaning rod 32 by using Velcro, which not only makes the cushion 34 more firmly installed, but also improves the patient's usage experience without being disturbed by the unstable position of the cushion 34.

[0050] The cushion 34 also has a shaping bending rod on one side surface close to the arc-shaped leaning rod 32. The shaping bending rod is made of a bendable metal wire, etc., and the cushion 34 is formed into a shape that fits the arc-shaped leaning rod 32 by bending the shaping bending rod, thereby adapting to the shape of the arc-shaped leaning rod 32 in different states.

[0051] Furthermore, the middle portion of the soft pad 34 is detachably mounted on the main rod body 31 by means of Velcro, magnets, ropes or double-sided adhesive tape.

[0052] In this embodiment, the design of the detachable cushion 34 fully considers the hygiene and convenience requirements in the medical scene. After the puncture operation, the cushion 34 will inevitably be contaminated with the patient's sweat, dandruff and other dirt. If it is not cleaned and disinfected in time, it is very easy to breed bacteria, cause cross infection, and threaten the health and safety of subsequent patients. Using a variety of detachable methods such as Velcro, magnets, ropes or double-sided tape, medical staff can flexibly choose according to actual conditions. Velcro is easy and quick to operate, and can be disassembled and installed by gently tearing and sticking, saving time; magnets are easy to accurately locate and can ensure that the cushion 34 is installed accurately every time; ropes are flexible and durable, suitable for fixing needs in some special scenarios; double-sided tape is simple and easy to use and low cost. No matter which method is used, it provides great convenience for medical staff to quickly remove the cushion 34 after surgery for disinfection, replacement and other maintenance operations, ensuring that the fixing frame always maintains a hygienic and safe state of use.

[0053] Furthermore, the frame 1 has a strip hole 12, which is located below the seat 2, and the seat 2 has a fastening screw hole 22; the limiting member 4 is a fastening screw, which is slidably arranged in the strip hole 12, and one end of the fastening screw is threadedly connected to the fastening screw hole 22. After the fastening screw is rotated, the seat 2 is locked or unlocked.

[0054] In this embodiment, the limiting design of the bar hole 12 and the fastening screw is a model of simplicity and efficiency. Structurally, it is very simple and clear, and easy for medical staff to understand and operate. In actual use, when the position of the seat 2 needs to be adjusted, the fastening screw can slide freely and smoothly in the bar hole 12, without hindering the movement of the seat 2, and the medical staff can quickly slide the seat 2 to the ideal position; and once the seat 2 is in place, it is only necessary to gently turn the fastening screw, and using the principle of threaded connection, the screw gradually screws into the fastening screw hole 22, and the seat 2 is tightly locked in the current position, effectively resisting any body movements of the patient during the puncture process and accidental collision interference from the outside world, ensuring that the relative position of the seat 2 and the leaning member 3 remains constant, building a solid line of defense for body position stability for the puncture operation, and ensuring the smooth progress of the puncture operation.

[0055] Furthermore, it also includes universal wheels 6 which are arranged at the bottom of the frame 1.

[0056] In this embodiment, the introduction of universal wheels 6 (which can be locked) endows the fixing frame with flexible and convenient mobility characteristics, which completely changes the disadvantages of the traditional fixing frame that is bulky and difficult to move. Especially in the face of emergency puncture surgery, the position of the patient is very important. After the ultrasound, the patient's posture should not be changed as much as possible. Through the fixing frame, the patient can be directly sent to the puncture operating room, which can minimize the change of the patient's posture and improve the accuracy of the puncture. After the operation, the fixing frame can be easily transferred to the storage area, saving manpower and handling costs. Moreover, the universal wheel 6 has a flexible steering function. Whether in the narrow ward corridor or the crowded corner of the operating room, medical staff can accurately control the fixing frame to make it arrive at the designated position smoothly, meet the needs of various usage scenarios, and greatly improve the efficiency of medical work.
