Description

Technical Field

[0001] This application belongs to the technical field of intraoperative fixation devices. More specifically, it relates to a multi-angle fixation device for aseptically maintaining an operating table. Background Art

[0002] Since the development of aseptic technique in the 19th century, a complete set of operation standards has been formed, known as the aseptic principle. This technique aims to reduce the risk of surgical infection and ensure patient safety. The aseptic principle puts forward strict requirements for positions and factors that may be contaminated by bacteria, such as the environment, personnel, skin of the surgical site, intraoperative operations, surgical gowns / gloves, and aseptic areas. Among them, the requirements for the aseptic area include defining "the instrument table and the area above the operating table after the sterile drapes are laid are regarded as the aseptic area." "The front of the surgeon's surgical gown (above the waist, below the shoulders, and in front of the anterior axillary line), and the hands to below 3 inches above the elbows are regarded as the aseptic area." Therefore, in current operating room operations, a fixation device for the operating table that adapts to the aseptic principle standard and can achieve the aseptic maintenance function is needed.

[0003] The typical existing intraoperative auxiliary fixation instruments have the following several schemes:

[0004] (1) The Chinese invention patent with the publication number CN109106411A discloses a voice-controlled six-degree-of-freedom surgical assistant instrument, including a fixture locking device provided on a fixed fixture. The top surface of the fixed fixture is connected to a main telescopic rod, the top of the main telescopic rod is connected to a main cloud platform, a main rotating table is provided on the top surface of the main cloud platform, the top surface of the main rotating table is connected to a stable platform, an angle-adjusting telescopic rod is provided inside the stable platform, the end of the angle-adjusting telescopic rod is connected to a secondary cloud platform, a six-degree-of-freedom adjusting device is connected to the top surface of the secondary cloud platform, the six-degree-of-freedom adjusting device is connected to a retractor connecting member, the retractor connecting member is connected to a retractor telescopic rod, and a retractor connecting interface is provided at the end of the retractor telescopic rod. It is convenient to be fixed on the operating table, and multiple different retractors can be connected to one retractor, which is convenient for adjusting the retraction distance and providing a good surgical field of view.

[0005] (2) The US patent with the publication number US20070149955A1, Surgical instrument positioning system and method of use, discloses a method for fixing surgical instruments during a surgical procedure, in which an opening is formed in the patient's body. The method includes inserting the distal part of the surgical instrument into the opening formed in the patient's body, tying a saddle to the proximal part of the surgical instrument to inhibit the rotation of the surgical instrument relative to the saddle, and fixing the saddle to the belt assembly by fixing the pulley rope fixed to the saddle to the belt assembly on the patient's body surface.

[0006] (3) Chinese Utility Model Patent with Publication Number CN203315097, a surgical instrument holding device, discloses a surgical instrument holding device connected to the mounting bracket of the operating table and the instrument holding seat for fixing surgical instruments. The end of the mounting bracket is provided with a base with a hollow cavity. A freely rotatable sphere is placed inside the base and a fastening device for fixing the position of the sphere is provided. The base has an opening, and the instrument holding seat is connected to the sphere through the opening. This surgical instrument holding device can hold and facilitate the movable fixation of the position and angle of surgical instruments such as laparoscopes, and can rotate the surgical instruments at multiple angles and provide stable positioning and support.

[0007] In summary, the prior art provides various devices for assisting in fixing surgical instruments during surgery. However, the existing devices cannot prevent the fixed surgical instruments from touching the non-sterile area of the operator during the operation. Therefore, there is still a need for a fixing device for the operating table that meets the standards of the sterile principle and can achieve the sterile holding function. Summary of the Invention

[0032] Please refer to togetherFigure 1 and Figure 2 , a multi - angle fixing device for a sterile - maintained operating table provided by an embodiment of the present application will be described hereinafter.

[0033] A multi - angle fixing device for a sterile - maintained operating table includes an operating - table fixing support 1 and a surgical - instrument clamp 2;

[0034] A primary position - adjusting group and a final - stage position - adjusting group are sequentially connected between the operating - table fixing support 1 and the surgical - instrument clamp 2. In this embodiment, the primary position - adjusting group includes a first position - adjusting rod 3 and a second position - adjusting rod 4, and the final - stage position - adjusting group includes a third position - adjusting rod 5. The connection structures among the operating - table fixing support 1, the primary position - adjusting group, and the final - stage position - adjusting group can all achieve angle adjustment and fixation. In this embodiment, a first angle - adjusting knob 6 is provided between the operating - table fixing support 1 and the first position - adjusting rod 3, a second angle - adjusting knob 7 is provided between the first position - adjusting rod 3 and the second position - adjusting rod 4, and a third angle - adjusting knob 8 is provided between the second position - adjusting rod 4 and the third position - adjusting rod 5. An angle - calibration device capable of marking the angle range in the direction away from the operating table is provided at the connection position between the primary position - adjusting group and the final - stage position - adjusting group. The angle - calibration device is used to record and indicate the safe movement angle range between the final - stage position - adjusting group and the operator.

[0035] The final - stage position - adjusting group refers to: the position - adjusting device that can adjust the longitudinal height of the fixed medical device and is the farthest from the operating - table fixing support, and any subsequent possible position - adjusting devices, and does not include the surgical - instrument clamp 2 itself.

[0036] The innovation direction of the present application does not lie in the specific structural improvement of the operating - table fixing support 1 and the surgical - instrument clamp 2. Therefore, in the illustrations of the present application, only a vice - like operating - table fixing support 1 and a simple inner - spring telescopic surgical - instrument clamp 2 are exemplarily adopted as a feasible solution for illustration, which does not limit the protection scope of the present application.

[0037] The multi - angle fixing device for a sterile - maintained operating table of the present application first completes the fixation between the operating - table fixing support 1 and the primary position - adjusting group, and then calibrates the safe movement angle between the final - stage position - adjusting group and the user through the angle - calibration device, records and indicates this safe movement angle. Under the guidance of this safe movement angle range, the final - stage position - adjusting group is fixed. During the operation, the final - stage position - adjusting group can be adjusted at any time within this range, without causing the final - stage position - adjusting group and the medical device fixed by this multi - angle fixing device for a sterile - maintained operating table to contact the non - sterile area of the operator's body.

[0038] In another embodiment of the present application, as Figure 1 and Figure 2As shown, the angle calibration device includes a first angle calibration ruler 10, a second angle calibration ruler 11, and an angle fixing component. One end of both the first angle calibration ruler 10 and the second angle calibration ruler 11 is movably connected to the connection position between the primary position adjustment group and the final position adjustment group. The angle fixing component is arranged at the same position and can fix the first angle calibration ruler 10 and the second angle calibration ruler 11. In this embodiment, the angle fixing component is an angle calibration ruler fixing button 12.

[0039] As a feasible implementation manner, in this embodiment, an angle calibration ruler is used as the angle calibration device, and its advantages are simple structure, low manufacturing cost, and low use difficulty. When in use, first fix the operating table fixing support 1 and the primary position adjustment group as described above. Then, visually align the first angle calibration ruler 10 with the shoulder of the operator with the lowest shoulder position, and visually align the second angle calibration ruler 11 with the waist of the operator with the highest waist position. Then, use the angle fixing component to fix the first angle calibration ruler 10 and the second angle calibration ruler 11. As an example, in this embodiment, the angle calibration ruler fixing button 12 is used to fix the first angle calibration ruler 10 and the second angle calibration ruler 11. Then, adjust the angle of the final position adjustment group within the longitudinal height range of the first angle calibration ruler 10 and the second angle calibration ruler 11. In this embodiment, the alignment and fixation process is carried out at a distance of one meter from the operator with the multi-angle fixing device for the sterile holding operating table (this setting is considered because when the angle of the final position adjustment group does not exceed the range defined by the angle calibration device, the size of the medical device to be fixed may still exceed the safety range. Therefore, the size margin of the medical device to be fixed is reserved when determining the angle). When the operator approaches the operating table, the medical device fixed by the multi-angle fixing device for the sterile holding operating table will not touch the non-sterile area of the operator.

[0040] In another embodiment of the present application, as Figure 1 、 Figure 2 and Figure 3 shown, the angle calibration device includes an angle calibration lamp 13. The light path of the angle calibration lamp 13 is parallel light. The connecting rod of the angle calibration lamp 13 and the primary position adjustment group achieve free rotation and short-term unstable fixation through friction.

[0041] As a feasible implementation manner, in this embodiment, an angle calibration lamp 13 is used for the alignment and fixation process. Its advantage is that, compared with the previous embodiment, this fixation process is more accurate. When in use, first fix the operating table fixing support 1 and the primary position adjustment group as described above, and then turn on the angle calibration lamp 13 so that its light shines on the shoulder position of the lowest one among the operators' shoulders. At the same time, adjust the direction of the first angle calibration ruler 10 to be collinear with the direction of the angle calibration lamp 13; then make the light of the angle calibration lamp 13 shine on the waist position of the highest one among the operators' waists, and at the same time adjust the direction of the second angle calibration ruler 11 to be collinear with the direction of the angle calibration lamp 13. Finally, use the angle fixing component to fix the first angle calibration ruler 10 and the second angle calibration ruler 11. As an example, in this embodiment, an angle calibration ruler fixing button 12 is used to fix the first angle calibration ruler 10 and the second angle calibration ruler 11, and then adjust the angle of the final position adjustment group within the longitudinal height range of the first angle calibration ruler 10 and the second angle calibration ruler 11. In this embodiment, the fixation process is carried out at a distance of one meter from the operator by the multi-angle fixing device for the aseptic holding operating table. When the operator approaches the operating table, the medical device fixed by the multi-angle fixing device for the aseptic holding operating table will not touch the non-aseptic area of the operator.

[0042] In this embodiment, the outer wall of the connecting rod of the angle calibration lamp 13 and the inner wall of the connection hole between it and the second position adjustment rod 4 are both made of rubber material. The outer wall of the connecting rod and the inner wall of the connection hole achieve a temporarily unstable fixation through friction, that is, when an external force is applied to the angle calibration lamp 13 and its connecting rod again, the angle of the angle calibration lamp 13 may rotate. Without the action of an external force, the relative angle between the angle calibration lamp 13 and the second adjustment rod 4 is stable.

[0043] In another embodiment of the present application, as Figure 1 、 Figure 4 and Figure 5 shown, a limiting device capable of limiting the longitudinal angle adjustment range of the final position adjustment group is provided between the primary position adjustment group and the final position adjustment group. In this embodiment, the limiting device includes a first limiter 14 for limiting the downward movement of the final position adjustment group and a second limiter 15 for limiting the upward movement of the final position adjustment group, and the limiting device is fixed by a limiter fixing button 16.

[0044] As a feasible implementation manner, this embodiment uses a limiting device to limit the longitudinal angle adjustment range of the final position adjustment group. Its advantage is that during the intraoperative operation, the operator does not need to be distracted to pay attention to the positions of the first angle calibration ruler 10 and the second angle calibration ruler 11. It can directly judge whether the medical device fixed by the multi-angle fixing device for the aseptic holding operating table reaches the safety range limit through touch, and can prevent the fixed medical device from further exceeding the safety range.

[0045] In another embodiment of the present application, Figure 3 As shown, the wavelength of the light of the angle calibration lamp 13 is 400-500nm.

[0046] As a feasible implementation method, the wavelength of the light of the angle calibration lamp 13 in this embodiment is 400-500nm, and the visible light colors in this band include purple, blue and cyan. The light of this color contrasts with the operator's white work clothes and avoids confusion with bright red blood, which can help the operator clearly confirm the relationship between the light of the angle calibration lamp 13 and the operator's body.

[0047] In another embodiment of the present application, Figure 1 and Figure 2 As shown, the connection structure between the primary position adjustment group and the final position adjustment group is a ball-and-socket connection structure 9, and a fixing member for fixing the angle of the ball-and-socket connection structure is provided at the ball socket of the ball-and-socket connection structure 9. In this embodiment, the fixing member is a third angle adjustment knob 8. As a feasible implementation, the connection structure between the primary position adjustment group and the final position adjustment group is a ball-and-socket connection structure 9, which can achieve adjustment in a multi-angle range while simplifying the structure.

[0048] In another embodiment of the present application, Figure 1 and Figure 2 As shown, the primary position adjustment group includes a longitudinal single-plane angle adjustment rod and a transverse single-plane angle adjustment rod. In this embodiment, the longitudinal single-plane angle adjustment rod is the first position adjustment rod 3, and the transverse single-plane angle adjustment rod is the second position adjustment rod 4. The primary position adjustment group is in the basic position of determining the safety range and activity of the final position adjustment group in the design scheme of the present application, and its stability is crucial to the implementation of the technical scheme of the present application. Therefore, a two-section longitudinal single-plane angle adjustment rod and a transverse single-plane angle adjustment rod are used to achieve multi-angle adjustment. Compared with the multi-plane angle adjustment rod, the fixation of the single-plane angle adjustment rod can usually achieve a larger fixed contact area, so the fixation of the single-plane angle adjustment rod is relatively more stable.

[0049] In another embodiment of the present application, Figure 1 and Figure 2 As shown, the contact surface between the surgical instrument clamp 2 and the surgical instrument is provided with a buffer pad 17. In order to prevent the surgical instrument clamp 2 from scratching the surgical instrument or causing deformation of the surgical instrument, the buffer pad 17 used in this embodiment serves as a fixed buffer between the surgical instrument clamp 2 and the surgical instrument. Compared with plane clamping, clamping the surgical instrument by the buffer pad 17 can enhance the friction between the surgical instrument clamp 2 and the surgical instrument, making the fixation between the surgical instrument clamp 2 and the surgical instrument more stable.

[0050] In another embodiment of the present application, it further includes a central controller capable of recording the angular calibration range calibrated by the angular calibration lamp. The central controller includes a first motion sensor capable of detecting the moving angle of the angular calibration lamp, a second motion sensor capable of detecting the moving angle of the final-stage position adjustment group, and an alarm.

[0051] Under certain special circumstances, the operator may need to temporarily or permanently adjust the surgical instruments fixed by the multi-angle fixing device for the aseptically maintained operating table to be used outside the safe range. To avoid the fixing device provided in the present application affecting the surgical operation, an angular calibration lamp is used to calibrate the safe range. The first motion sensor detects the angle of the angular calibration lamp. When the calibrated angle is reached, the central controller records the upward angle and the downward angle. The second motion sensor detects the moving angle of the final-stage position adjustment group. When the moving angle of the final-stage position adjustment group exceeds the recorded upward angle and downward angle range, the alarm gives a short alarm reminder, but does not physically restrict the operator's use. When the moving angle of the final-stage position adjustment group returns to the safe range, the alarm sounds briefly again to indicate.

[0052] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
