DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The purpose of the present invention is to provide a traction frame and an operating table to solve the problems existing in the above-mentioned prior art, which can be installed in conjunction with different operating tables to enable the operation to be carried out in a timely and smooth manner.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] The existing bone traction device needs to be installed in conjunction with an orthopedic bed, which makes the application range of the traction device narrow. When the number of orthopedic beds is insufficient, it is impossible to perform traction on the patient in time. In order to solve this technical problem, the present invention provides a traction frame, such as Figure 1 、 Figure 3 As shown, the present invention comprises a positioning clamp 1, the opening of which is adjustable and can be fixedly clamped to the bed frame of an operating table; the bottom of an adjustment frame is mounted on the positioning clamp 1; a traction portion 5 is mounted on the adjustment frame, used to support the part to be tractioned, and the adjustment frame can adjust the traction portion 5 to a set position. The traction portion 5 includes a positioning pad, which includes an integrally formed horizontal pad and a vertical pad. The outer side of the vertical pad is fixedly connected to the adjustment frame, so that the end of the part of the human body to be tractioned can be placed and tied to the traction portion 5 for traction. Since different operating tables have a common feature that they all have a bed frame, the present invention can use the positioning clamp 1 to fix the traction frame to different operating tables, and can be installed with different operating tables to ensure timely and smooth surgery. The bed frame mainly includes a frame as the main body of the operating table, and the frame is provided with structures such as guardrails or supporting columns. The opening clamp is generally clamped and fixed to the guardrails or columns. The guardrails or columns of the bed frames of different operating tables have different sizes. Therefore, the opening size of the positioning clamp 1 of the present invention can be adjusted, thereby adapting to the needs of supporting operating tables of different sizes.

[0026] In one embodiment, the positioning clamp 1 includes a base 103, a first clamping arm 101 and a second clamping arm 102. The first clamping arm 101 is provided with a clamping groove on the side close to the second clamping arm 102, and the second clamping arm 102 is provided with a clamping groove on the side close to the first clamping arm 101. The two clamping grooves are arranged opposite to each other and can be buckled on the bed frame of the operating bed. Through the semicircular or arc-shaped clamping groove structure, the first clamping arm 101 and the second clamping arm 102 can be more accurately buckled and clamped on the pipe column or guardrail of the bed frame, and are more compatible with the cylindrical structure of the pipe column or guardrail; one end of the first clamping arm 101 is fixed on the base 103, and one end of the second clamping arm 102 is movably provided on the base 103, and after the second clamping arm 102 moves close to or away from the first clamping arm 101 to a set position, it can be fixed thereto. On the base 103, an opening of the positioning clamp 1 can be formed between the first clamping arm 101 and the second clamping arm 102. When installation is required, the positioning clamp 1 is first moved so that the pipe column or guardrail of the bed frame enters the opening of the positioning clamp 1, and the clamping groove of the first clamping arm 101 is fixedly buckled on one side of the pipe column of the bed frame. Then, the second clamping arm 102 is moved so that the second clamping arm 102 gradually approaches the first clamping arm 101 until the clamping groove of the second clamping arm 102 is fixedly buckled on the side of the pipe column or guardrail away from the first clamping arm 101. The pipe column or guardrail is fixedly clamped by the first clamping arm 101 and the second clamping arm 102. Then, the second clamping arm 102 is fixed to the base 103 to realize the installation of the traction frame. The installation process is convenient and has a wide range of applications. It can be adapted to operating tables of various specifications.

[0027] There is no restriction on the fixing method of the second clamping arm 102. In one embodiment, a vertical slide groove 104 is provided on one side of the base 103, and one end of the second clamping arm 102 is slidably arranged in the slide groove 104, and a locking rod 105 is threadedly passed through the top of the slide groove 104. The locking rod 105 of this embodiment is a screw, and the bottom of the screw can abut against the upper part of the end of the second clamping arm 102 located in the slide groove 104, and the screw is located at the end away from the first clamping arm 101, so that the bottom of the screw can abut against the second clamping arm 102 by twisting the screw, thereby driving the second clamping arm 10 2 moves toward one end close to the first clamping arm 101. As the screw continues to be turned, the second clamping arm 102 is gradually limited in the sliding groove 104. The screw can be used to gradually reduce the opening between the second clamping arm 102 and the first clamping arm 101, and finally achieve the fixed clamping effect on the guardrail or pipe column; when it is necessary to disassemble the traction frame, the screw is turned in the opposite direction to release the limit of the second clamping arm 102, thereby allowing the second clamping arm 102 to move away from the first clamping arm 101, so that the opening becomes larger, making it easier to remove the positioning clamp 1 from the guardrail or pipe column.

[0028] In addition to the above structure, the positioning clamp 1 may also adopt other structures in another embodiment. For example, the first clamping arm 101 and the second clamping arm 102 may be respectively connected to the same rotating shaft with their respective connecting flanges, and the first clamping arm 101 and the second clamping arm 102 may both rotate around the rotating shaft, and a torsion spring is provided on the rotating shaft, which abuts against the first clamping arm 101 located at the inner side of one end of the rotating shaft and the second clamping arm 102 located at the inner side of one end of the rotating shaft, so that under the action of the torsion spring, the first clamping arm 101 located at the inner side of the other end of the rotating shaft and the second clamping arm 102 located at the inner side of the rotating shaft are in contact with each other. The inner side of the other end of the shaft abuts against the inner side. When the first clamping arm 101 and the second clamping arm 102 are manually squeezed and the end abutting the torsion spring, the first clamping arm 101 located on the inner side of the other end of the rotating shaft and the second clamping arm 102 located on the inner side of the other end of the rotating shaft are opened to form an opening of the positioning clamp 1, which can be used to clamp it on the guardrail or pipe column. After moving the positioning clamp 1 to the set position, release the end of the first clamping arm 101 and the second clamping arm 102 abutting against the torsion spring, so that the positioning clamp 1 is fixed at the set position, and the traction frame is installed at the set position of the operating bed.

[0029] Because different patients have different body shapes and different surgical sites result in different traction positions, traditional traction frames are fixed in position and cannot be used for traction on different patients and at different surgical sites. To address this technical problem, the present invention, in one embodiment, provides an adjustable frame that can adjust the position and angle of the traction unit 5, making it suitable for traction operations on different surgical sites on patients of various body shapes. The adjustment frame of this embodiment includes a support rod 2, the bottom of the support rod 2 is fixedly connected to the positioning clamp 1, and the top of the support rod 2 is hinged with an adjusting block 3, and the angle of the adjusting block 3 and the length direction of the support rod 2 can be adjusted; a horizontal connecting rod 4 is provided on the adjusting block 3, and a traction part 5 is provided at one end of the horizontal connecting rod 4. The horizontal connecting rod 4 can move back and forth along the axial direction of the horizontal connecting rod 4, and can be fixed on the adjusting block 3 after moving to the set position, so that the front and rear position and angle of the traction part 5 can be adjusted. In order to make the height of the traction part 5 also adjustable, in one embodiment, the support rod 2 can be designed as a telescopic structure, for example, the support rod 2 can be designed as a sleeve and sleeve rod structure, the bottom of the sleeve is fixedly connected to the positioning clamp 1, and the top of the sleeve is provided with a sleeve rod, which can be threaded or snap-connected to the sleeve, and then the position of the sleeve rod in the sleeve can be adjusted to achieve the adjustment of the overall height of the support rod 2, and the top of the sleeve rod is hinged with an adjusting block 3 to achieve the adjustment of the height of the adjusting block 3 and the traction part 5.

[0030] To further improve the accuracy of the traction position, in one embodiment, a high-precision fine-tuning assembly is also designed. The fine-tuning assembly is set at the connection between the positioning clamp 1 and the support rod 2. The fine-tuning assembly includes a screw, a nut, and a fine-tuning knob. The screw is movably mounted on the positioning clamp 1 via a bearing. The nut is threaded onto the screw, and a fine-tuning knob is fixed at one end of the screw. After the positioning clamp 1 is used to complete the initial tightening, the medical staff rotates the fine-tuning knob, and the screw drives the nut to move horizontally along the screw, thereby driving the support rod 2 and the traction part 5 to perform millimeter-level translation and fine-tuning, meeting the surgical requirements for the precise position of the traction frame and ensuring the accurate traction direction.

[0031] In one embodiment, the horizontal connecting rod 4 can be a threaded rod structure. A nut is provided on the adjustment block 3, and the threaded rod is inserted into the nut to form a screw-nut structure. By turning a knob at one end of the threaded rod, the forward and backward movement of the axis of the horizontal connecting rod 4 can be adjusted. In this embodiment, a vertical screw is threaded through the nut above the nut. The top of the vertical screw is provided with an extension flange 10 that serves as a knob. By turning the extension flange 10, the vertical screw rotates downward. When the bottom of the vertical screw is fixedly abutted against the side wall of the horizontal connecting rod 4, the horizontal connecting rod 4 is fixed. By turning the extension flange 10 in the opposite direction, the fixation of the horizontal connecting rod 4 can be released, thereby achieving horizontal adjustment of the traction portion 5. In this embodiment, the adjusting block 3 is hinged to the top of the support rod 2 through a rotating shaft, that is, the horizontal hole opened in the top of the support rod 2 is penetrated by a rotating shaft, and both ends of the rotating shaft are connected to the adjusting block 3, so that the adjusting block 3 can be rotated up and down. A lock is provided at the connection position between the adjusting block 3 and the top of the support rod 2. The lock structure is not restricted and a mature known structure is adopted. When the adjusting block 3 is rotated to the desired angle, the adjusting block 3 can be fixed in this position by the lock, meeting the needs of patients of different heights and different surgical sites.

[0032] In one embodiment, the traction unit 5 includes a multi-jointed positioning arm, one end of which is connected to the adjustment frame and the other end is connected to a positioning pad. The positioning pad includes an integrally formed horizontal pad and vertical pad. The outer side of the vertical pad is fixedly connected to one end of the multi-jointed positioning arm. The multi-jointed positioning arm can be flexibly adjusted according to the patient's body shape and fracture location. The multi-jointed positioning arm can be made of a flexible material or an industrial robotic arm structure. A soft silicone pad is provided at the end of the multi-jointed positioning arm to increase the comfort and stability of contact with the patient's limb.

[0033] To further enhance comfort and traction, in one embodiment, a hip pad 7 is provided, on which a perineal column 8 is fixed. The hip pad 7 can be fixed to the operating table, thereby improving the patient's comfort on the operating table, and the perineal column 8 can assist in traction. Furthermore, the hip pad 7 and the perineal column 8 can be provided separately, with the hip pad 7 and the perineal column 8 being separately provided on the operating table body 6. When the perineal column 8 is no longer needed for traction, only the hip pad 7 can be retained.

[0034] Based on the above technical solution, the present invention also provides an operating table, such as Figure 2 As shown, it includes an operating bed body 6 and the above-mentioned traction frame. The operating bed body 6 includes a bed frame, and the bed frame is provided with a bed frame rod 9. The traction frame is installed on the bed frame rod 9. The hip pad 7 of the present invention can be replaced with an adjustable perineal protection pad. Its height, angle and hardness can be adjusted as needed to reduce the pressure on the perineum and avoid damage during traction.

[0035] In one embodiment, a plurality of marking points are provided on the side wall of the operating bed body 6, and the traction frame can be moved and fixed to the corresponding marking points. The marking points can be reflective markings or electromagnetic markings. During installation, the marking points can be quickly identified to guide the traction frame to accurately align, thereby reducing manual calibration time and errors.

[0036] In one embodiment, an accessory platform is installed on one side of the traction frame, which is fixed using a combination of magnetic attraction and snap fasteners. The accessory platform can be installed with surgical lighting to provide ample light to the surgical area, and can also carry instrument trays to facilitate access to tools during surgery, improving the convenience of surgical operations.

[0037] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
