Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, and in particular relates to an electric traction bed for orthopedic surgery. Background Technology

[0002] Orthopedic surgical traction beds are widely used medical devices in orthopedic surgery. They primarily apply traction to specific parts of the patient's body through mechanical transmission, restoring fractured or dislocated areas to their normal or near-normal anatomical position. This creates favorable conditions for precise subsequent surgical procedures and fracture healing. Especially during cervical spine surgery, the patient lies prone on the operating table. Medical staff fix the patient's head using a surgical head frame and apply traction through a weight at one end of the traction mechanism to better expose the cervical spine, ensuring the smooth progress of the subsequent surgery. However, current orthopedic surgical traction beds have complex structural designs, cumbersome installation and debugging procedures, requiring significant time and effort from medical staff, thus affecting surgical efficiency. Furthermore, they have limitations in achieving precise adjustments to traction force and angle, making it difficult to meet the high-precision requirements of complex orthopedic surgeries and impacting surgical outcomes.

[0003] Therefore, there is an urgent need to design an electric traction bed for orthopedic surgery that has high adjustment precision and is easy to operate. Utility Model Content

[0014] Compared with the prior art, the electric traction bed for orthopedic surgery of this utility model has the following beneficial effects:

[0015] (1) This utility model uses symmetrically arranged liftable columns to raise or lower the bed board support frame or tilt the head and tail, which can quickly match different surgical needs and ensure the stability of the patient's position during the operation. At the same time, after the patient's head is fixed by the surgical head frame, the adjustable traction fixation frame is moved by adjusting the traction fixation slider, which in turn moves the surgical head frame to the appropriate position. The traction fixation slider is locked and fixed by the first fixing locking piece, so as to achieve horizontal stable traction of the patient's cervical spine. The operation is simple, saves manpower, and allows doctors to focus on the surgical operation and shorten the operation time.

[0016] (2) By designing the angle α between the central axes of the left and right vertical arms in the surgical head frame as an acute angle, compared with the existing U-shaped structure of the surgical head frame, the distance between the two crossbeams along the length direction on the bed board support frame is smaller, which makes it easier for doctors to get closer to the patient's head during surgery and create a better operating space, especially suitable for complex fractures or cervical spine surgery.

[0017] (3) In this utility model, the surgical head frame, bed board support frame and traction clamp are all made of transmissible materials, which makes it convenient for doctors to cooperate with the image navigation system to make the surrounding structures of the surgical field fully displayed in the image, eliminate image interference, reduce the risk of accidental injury, and at the same time adjust the traction force in real time according to the fluoroscopic image, improve the adjustment accuracy, and meet the requirements of high-precision operation for complex orthopedic surgery.

Detailed Implementation

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] The following is combined with Figures 1 to 5 The present invention will be described in detail with specific embodiments.

[0027] This utility model provides an electric traction bed for orthopedic surgery, including a height-adjustable operating table base 1, a cervical traction component 2, and a surgical head frame 3. The height-adjustable operating table base 1 includes two symmetrically arranged height-adjustable columns 11, with a bed board support frame 12 between the two columns 11. The cervical traction component 2 includes two symmetrically arranged traction fixing sliders 21 on the bed board support frame 12. The two traction fixing sliders 21 are slidably connected to the bed board support frame 12 along its length, and each traction fixing slider 21 is provided with a first fixing locking element 22. An adjustable traction fixing frame 23 is provided between the two traction fixing sliders 21, and the adjustable traction fixing frame 23 is fixedly connected to the surgical head frame 3.

[0028] The adjustable operating table base 1 of this utility model also includes a support base 13 fixedly installed at the lower end of the adjustable column 11 and a control system (not shown in the figure). The lower end surface of the support base 13 is provided with rollers 14 for easy movement. A length adjustment rod 15 is also provided between the two support bases 13 along the length direction of the bed board support frame 12. In this embodiment, the bed board support frame 12 is a rectangular frame. The two ends of the bed board support frame 12 are fixedly connected to the lifting ends of the adjustable column 11. The upper end surface of the bed board support frame 12 is provided with a bed board (not shown in the figure) for supporting the patient's body. Medical staff can adjust the distance between the two adjustable columns 11 through the length adjustment rod 15 to meet the needs of patients of different heights. The control system moves the liftable column 11 up and down to reduce fatigue caused by the surgeon bending over or overstretching during the operation. In this embodiment, the traction and fixation slider 21 is composed of a metal block with an inverted U-shaped cross section and a rectangular fixing cover plate that matches the U-shaped opening. The rectangular fixing cover plate is hinged to one end of the inverted U-shaped metal block. The first fixing locking member 22 is a T-shaped plum blossom handle tightening member. The inverted U-shaped metal block is fastened to the crossbeam of the bed board support frame 12. After the rectangular fixing cover plate is covered with the lower end face of the crossbeam of the bed board support frame 12, the rectangular fixing cover plate is tightened upward by rotating the T-shaped plum blossom handle tightening member, so that the traction and fixation slider 21 is adjusted to a suitable position and locked. During cervical spine surgery, the patient is usually in a prone position. The medical staff first fixes the surgical head frame 3 to the patient's head, and then moves the adjustable traction fixation frame 23 to the surgical head frame 3 by moving the traction fixation slider 21. The traction fixation slider 21 on both sides is locked and fixed by two first fixing locking pieces 22. One end of the traction rope (not shown in the figure) is connected to the adjustable traction fixation frame 23, and the other end is connected to a weight (not shown in the figure), thereby achieving horizontal and stable traction on the patient's cervical spine. The operation is simple and convenient, saves manpower, and allows doctors to focus on the surgical operation, shortening the operation time.

[0029] For details, please refer to Figures 1-4In some embodiments, the adjustable traction fixation frame 23 includes a linear optical axis 230 disposed between two traction fixation sliders 21.

A fixation frame fixing seat 232 is slidably connected on the linear optical axis 230, and a head frame fixing assembly 233 is provided on the fixation frame fixing seat 232. The head frame fixing assembly 233 is fixedly connected to the surgical head frame 3. In this embodiment, the linear optical axis 230 consists of two parallel, spaced-apart smooth metal rods. The two linear optical axes 230 allow for smoother and more reliable forward and backward movement of the head frame fixing assembly 233 on the linear optical axis 230.

[0030] For details, please refer to Figures 1-4 In some embodiments, the cervical traction assembly 2 further includes a traction handle bracket 24, a first traction wheel component 25, and a second traction wheel component 26. The two ends of the traction handle bracket 24 are fixedly connected to two optical axis fixing seats 231, respectively. The first traction wheel component 25 and the second traction wheel component 26 are fixedly connected, from low to high, to a height-adjustable column 11 near the surgical head frame 3. In this embodiment, the traction handle bracket 24 is a U-shaped metal frame. When performing cervical traction on the patient, the horizontal height of the lower end face of the first traction wheel component 25 is consistent with the horizontal height of the traction handle bracket 24. First, the medical staff fix one end of the traction rope to the middle of the traction handle bracket 24. Then, the other end of the traction rope passes horizontally through the first traction wheel component 25 and vertically upward through the second traction wheel component 26. After passing over the liftable column 11, it is fixedly connected to a weight block with appropriate weight configuration. In order to reduce the loss of traction friction, there are two second traction wheel components 26, which are symmetrically arranged on both sides of the liftable column 11. This structure will not allow the weight block to interfere with the use of other equipment during the operation, such as the C-arm fluoroscopy machine, and will not affect the doctor's operating space.

In this embodiment, the fixing bracket slider 2320 is a square metal block with two through holes laterally provided on the square metal block that are adapted to the linear optical axis 230. The linear optical axis 230 passes through the through holes and is fixedly connected to the optical axis fixing bases 231 on both sides. The second fixing locking member 2321 is a Torx handle screw threaded onto the upper end face of the fixing bracket slider 2320. After moving the fixing bracket slider 2320 to a suitable position, medical staff only need to tighten the second fixing locking member 2321 downwards to fix the fixing bracket slider 2320 onto the linear optical axis 230. The operation is convenient and the structure is simple.

[0032] For details, please refer to Figures 1-4 In some embodiments, the optical axis fixing seat 231 includes a guide rail 2310 fixedly mounted on the upper end face of the traction fixing slider 21.

The third fixing locking member 2312 also adopts a robust, durable, and low-cost L-shaped rotary handle. In this embodiment, the surgical head frame 3 is initially fixed by moving and locking the traction fixing slider 21. Then, the guide rail slider 2311 is moved along the guide rail 2310, so that the fixing frame fixing seat 232, which is fixedly connected to the optical axis fixing seat 231, moves horizontally. When the fixing frame fixing seat 232 moves to the appropriate position, it is tightened by the third fixing locking member 2312, so that the guide rail slider 2311 is fixed on the traction fixing slider 21, thereby achieving the second fixation of the patient's head on the surgical head frame 3.

[0033] For details, please refer to Figures 1-4 In some embodiments, the head frame fixing assembly 233 includes a clamp fixing seat 2330, a traction upper arm 2331, a traction lower arm 2332, and a traction clamping member 2333. The upper end of the clamp fixing seat 2330 is fixedly connected to the fixing frame slider 2320, the lower end of the clamp fixing seat 2330 is hinged to one end of the traction upper arm 2331, the other end of the traction upper arm 2331 is hinged to one end of the traction lower arm 2332, the other end of the traction lower arm 2332 is fixedly connected to one end of the traction clamping member 2333, and the other end of the traction clamping member 2333 is fixedly connected to the surgical head frame 3. Preferably, the clamp fixing seat 2330, the traction upper arm 2331 and the traction lower arm 2332 are hinged and locked together by the fourth fixing locking member 2334 and the fifth fixing locking member 2335 respectively. The fourth fixing locking member 2334 and the fifth fixing locking member 2335 are both Torx handle screws. The upper and lower ends of the traction clamping member 2333 are provided with first toothed members. The traction lower arm 2332 and the surgical head frame 3 are provided with second toothed members that are compatible with the first toothed members. The first toothed members and the second toothed members are connected by a rotating nut member 2336. By rotating the traction clamping member 2333, the angle of the surgical head frame 3 can be finely adjusted, and the adjusted surgical head frame 3 can be locked and fixed by rotating the nut member 2336. This utility model allows for the adjustment of the distance and angle between the surgical head frame 3 and the cervical traction assembly 2 via the clamp fixing seat 2330, traction upper arm 2331, traction lower arm 2332, and traction clamping member 2333. The adjustment is highly accurate and simple and convenient.

[0034] For details, please refer to Figures 1-5In some embodiments, the surgical head frame 3 is a three-screw craniocerebral surgical head frame. The surgical head frame 3 includes a right adjusting arm 31, a left fixing arm 32, and an adjusting fixing member 33. The upper end of the right adjusting arm 31 is provided with a single-headed nail adjusting member 34, and the upper end of the left fixing arm 32 is provided with a double-headed nail adjusting member 35. The left adjusting arm 31 and the right fixing arm 32 adjust and fix the distance between the single-headed nail adjusting member 34 and the double-headed nail adjusting member 35 through the adjusting fixing member 33.

[0035] For details, please refer to Figures 1-5 In some embodiments, the right adjusting arm 31 includes an integrally formed right vertical arm 310 and right horizontal arm 311, and the left fixing arm 32 includes an integrally formed left vertical arm 320 and left horizontal arm 321.

In this embodiment, a rack is provided on the lower end face of the right horizontal arm 311, and a rack groove adapted to the rack is provided in the left horizontal arm 321. By pulling the right vertical arm 310 and the left vertical arm 320, the distance between the nail heads on the single-headed nail adjusting member 34 and the double-headed nail adjusting member 35 can be adjusted to match the size of the patient's head, and the two are fixed by the adjusting fixing member 33, thereby achieving stable fixation of the patient's head. In this embodiment, the intersection of the right vertical arm 310 and the left vertical arm 320 is V-shaped. Compared with the existing surgical head frame where the left adjusting arm and the right fixed arm are U-shaped, this allows the distance between the two crossbeams along the length of the bed board support frame 2 to be smaller, thus making it easier for doctors to get closer to the patient's head during surgery and creating a better operating space. This is especially suitable for complex fractures or cervical spine surgery.

[0036] For details, please refer to Figures 1-5 In some embodiments, the surgical head frame 3, the bed support frame 12, and the traction clamp 2333 are all made of translucent materials. Preferably, the translucent material is carbon fiber. This embodiment, by making the surgical head frame 3, the bed support frame 2, and the traction clamp 2333 all made of translucent materials, facilitates the surgeon's use of the image navigation system to ensure the surrounding structures of the surgical field are fully displayed in the image, eliminating image interference, reducing the risk of accidental injury, and also allowing for real-time adjustment of the traction force based on fluoroscopic images, improving adjustment accuracy and meeting the high-precision operation requirements of complex orthopedic surgeries.

[0037] For details, please refer to Figures 1-5In some embodiments, the first traction wheel component 25 includes a first traction roller crossbar 250 fixedly connected to the liftable column 11, and a first traction roller 251 is sleeved on the first traction roller crossbar 250; the second traction wheel component 26 includes a second traction block 260, and a second traction roller 261 rotatably connected to the second traction block 260. One end of the traction rope is fixedly connected to the traction handle bracket 24, and the other end of the traction rope passes through the first traction roller 251 and the second traction roller 261 in sequence before being fixedly connected to the weight block.

Medical personnel can adjust the fixed position of the first traction wheel component 25 according to actual needs, and the second traction wheel component 26 is fixed above the first traction wheel component 25.

[0038] The working principle of this electric traction bed for orthopedic surgery is as follows:

[0039] (1) The adjustable column 11 is moved by the control system so that the bed board support frame 12 is moved to a suitable height;

[0040] (2) Snap the two traction fixing sliders 21 in the cervical traction assembly 2 onto the bed board support frame 12 respectively;

[0041] (3) Take the surgical head frame 3 and adjust the distance between the single-headed nail adjustment piece 34 and the double-headed nail adjustment piece 35 by pulling the right adjustment arm 31 in the surgical head frame 3 according to the size of the patient's head;

[0042] (4) After the patient lies prone on the bed board of the bed board support frame 12, fix the surgical head frame 3 to the patient's head;

[0043] (5) Move the traction fixing slider 21 closer to the surgical head frame 3, move the fixing frame slider 2320 back and forth, so that the head frame fixing assembly 233 is aligned with the surgical head frame 3 and then fixedly connected, and the fixing slider 21 and the fixing frame slider 2320 are locked and fixed by the first fixing locking member 22 and the second fixing locking member 2321 respectively.

[0044] (6) Rotate the traction arm 2331, traction arm 2332 and traction clamp 2333 to finely adjust the distance between the fixed frame slider 2320 and the surgical head frame 3, and make fine angle adjustments to the surgical head frame 3 by rotating the traction clamp 2333. Finally, rotate the fourth fixing locking part 2334, the fifth fixing locking part 2335 and the rotating nut part 2336 to lock and fix it.

[0045] (7) One end of the traction rope is fixedly connected to the middle of the traction handle bracket 24, and the other end passes horizontally through the first traction wheel component 25 and then vertically upward through the second traction wheel component 26, and then crosses the liftable column 11 and is fixedly connected to a weight block with appropriate weight configuration.

[0046] (8) Under the force of gravity of the heavy block, the traction handle bracket 24 moves to the left, which in turn drives the guide rail slider 2311 to move to the left along the guide rail 2310, thereby driving the surgical head frame 3 to move to the left. Finally, the guide rail slider 2311 is fixed on the traction fixed slider 21 by the third fixing locking member 2312, so as to achieve stable traction of the patient's cervical spine.

However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
