Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, and in particular to a urological surgical support device. Background Technology
[0002] Urologists need to maintain a specific arm position during surgery. The stability and accuracy of this position are crucial for ensuring the smooth progress of the procedure and the patient's safety.
[0003] I. Surgical Procedure Requirements
[0004] Precision: Urological surgeries often involve delicate anatomical structures and complex physiological systems, such as the kidneys, ureters, and bladder. Surgeons need to use precise arm movements to control surgical instruments in order to accurately cut, suture, or repair these structures.
[0005] Stability: During surgery, the surgeon's arm needs to remain stable to avoid affecting the surgical outcome or increasing surgical risks due to tremors or instability. A stable arm position helps the surgeon better control surgical instruments and reduces the possibility of misoperation.
[0006] II. Surgical Positioning Requirements
[0007] Surgical Positions: Urological surgeries often employ various positions, such as supine, prone, and lateral decubitus. Different surgical positions place different demands on the surgeon's arm posture. For example, in lateral decubitus surgery, the surgeon may need to adjust the height and angle of their arm to better expose the surgical field and reduce unnecessary muscle tension.
[0008] To improve the precision and stability of surgical procedures, reduce errors, optimize the surgical environment, protect patient safety, and reduce surgeon fatigue, surgeons need to support their arms during surgery. Arm support devices must have the following functions:
[0009] I. Stable support function
[0010] Arm support: Urological surgeries often require doctors to maintain a specific arm posture for extended periods. Arm supports should provide stable and comfortable support to reduce arm fatigue and muscle tension, thereby maintaining the stability and precision of the surgical procedure.
[0011] Height and angle adjustment: The surgical support should have height and angle adjustment functions to adapt to the needs of different surgical positions and doctors' operating habits, help doctors better expose the surgical field and improve surgical efficiency.
[0012] Flexible adjustment: The surgical support should be flexible and adjustable so that it can be fine-tuned as needed during the operation to ensure the smooth progress of the operation.
[0013] Existing arm support devices are generally connected by fasteners. Adjustment requires loosening or tightening the fasteners, which is not only time-consuming, but also results in the loss of adjustment or support functions when the fasteners fail, affecting the smooth progress of the operation and even posing safety risks to the patient.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:
[0036] refer to Figure 1 A urological surgical support device includes a height adjustment device 100 and two adjustment devices 200 fixed to the upper part of the height adjustment device 100.
[0037] refer to Figure 2 The height adjustment device 100 includes a base 110, with lead screws 130 rotatably connected to both sides of the base 110. Each lead screw 130 is threadedly connected to a lifting rod 120, which is slidably connected to the base 110. The lower parts of the two lead screws 130 are connected to a shaft 140 via bevel gears.
[0038] refer to Figures 2 to 5 The adjusting seat 210 has two symmetrical bushings 111 on both sides. Each bushing 111 has a bushing notch 113 at the bottom and a lead screw hole 114 coaxial with the bushing 111 at the bottom. A lead screw 130 is rotatably connected to each lead screw hole 114. The lower part of one lead screw 130 is connected to a motor 170 fixed to the lower part of the base 110. The lower parts of the two lead screws 130 are fixedly connected to a first bevel gear 150. Each first bevel gear 150 and a second bevel gear 160 mesh with each other. The two second bevel gears 160 are fixedly connected to both sides of the shaft 140. The shaft 140 is rotatably connected to the bearing seat 115 on the upper part of the base 110.
[0039] refer to Figures 2 to 5The inner side of the bushing 111 is provided with a bushing keyway 112, and the outer side of the lifting rod 120 is provided with a lifting rod key 122. The lifting rod 120 is slidably connected to the bushing 111, and the lifting rod key 122 is slidably connected to the bushing keyway 112. The nut 121 inside each lifting rod 120 is threadedly connected to the lead screw 130.
[0040] When the motor 170 rotates, it drives the lead screw 130 connected to it to rotate. When the lead screw 130 rotates, it drives the first bevel gear 150 connected to it to rotate. The rotation of the first bevel gear 150 drives the second bevel gear 160 and the shaft 140 connected to it to rotate. The rotation of the shaft 140 drives the first bevel gear 150, the second bevel gear 160 and the lead screw 130 on the other side to rotate, so that the lead screws 130 on both sides rotate synchronously. The rotation of each lead screw 130 drives its respective lifting rod 120 to move up and down, so as to adjust the height of the doctor's arm.
[0041] refer to Figures 6 to 8 The adjustment device 200 includes an adjustment seat 210, a central shaft 230 slidably connected in the middle of the adjustment seat 210, the central shaft 230 and the adjustment seat 210 being coupled by a thread and a steel ball, a rotating seat 220 rotatably connected to one side of the central shaft 230, the rotating seat 220 and the central shaft 230 being coupled by a thread and a steel ball, a support seat 240 rotatably connected to the upper part of the rotating seat 220, the support seat 240 and the rotating seat 220 being coupled by a spring and a steel ball.
[0042] refer to Figures 6 to 12 The cylindrical surface of the adjusting seat 210 is provided with an adjusting seat shaft 213, which is fixedly connected to the upper part of the corresponding lifting rod 120. The adjusting seat 210 is provided with an adjusting seat hole 211 in the middle and an adjusting seat spline hole 214 on one side. The central shaft 230 is slidably connected to the adjusting seat hole 211, and the spline shaft 235 on the outer side of the central shaft 230 is slidably connected to the adjusting seat spline hole 214. The central shaft 230 is provided with a set of evenly distributed axial grooves 231 in the axial direction. The cylindrical surface of the adjusting seat 210 is provided with a radial adjusting seat screw hole 212. The adjusting seat screw hole 212 is threadedly connected to a first bolt 2501. The adjusting seat screw hole 212 is provided with a first spring 2601 and a first steel ball 2701 inside. The first steel ball 2701 is stuck in one of the axial grooves 231. The first bolt 2501 pushes against the first spring 2601, and the first spring 2601 pushes the first steel ball 2701 in the axial groove 231.
[0043] When the central shaft 230 is pushed, the contact surface between the axial groove 231 and the first spring 2601 generates a thrust. When the radial component of the thrust is greater than the elastic force of the first spring 2601, the first steel ball 2701 is pushed out of the axial groove 231 by the radial force of the axial groove 231. The pushed-out first steel ball 2701 enters the adjusting seat screw hole 212. At this time, the central shaft 230 moves along the shaft. When the axial movement distance of the central shaft 230 meets the requirements, the pushing of the central shaft 230 is stopped. At this time, the first steel ball 2701 is again stuck into one of the axial grooves 231 under the action of the first spring 2601. The central shaft 230 is axially positioned. The spline shaft 235 slides through the spline hole 214 of the adjusting seat, so that the central shaft 230 can only move axially and cannot rotate. The first spring 2601 and the first steel ball 2701 between the adjusting seat 210 and the central shaft 230 have the following functions: First, they allow the axial position of the central shaft 230 relative to the rotating seat 220 to be freely adjusted; second, they ensure that the axial positions of the adjusting seat 210 and the central shaft 230 are relatively fixed during surgery; third, they avoid the problem that when the adjusting seat 210 and the central shaft 230 are connected by traditional fasteners, the position of the adjusting seat 210 and the central shaft 230 cannot be adjusted or fixed when the fastener fails. Rotating the first bolt 2501 can adjust the preload of the first spring 2601 to ensure the relative fixation of the axial position of the adjusting seat 210 and the central shaft 230. The axially moving central shaft 230 can adjust the left and right distance of each arm.
[0044] refer to Figures 6 to 12 A shoulder 232 is provided on one side of the central shaft 230, and a shaft segment 233 is provided on the outer side of the shoulder 232. A set of evenly distributed shaft segment grooves 234 are provided on the cylindrical surface of the shaft segment 233. A rotating seat 220 is provided in the middle of the rotating seat hole 221, and a countersunk hole 225 is provided on one side of the rotating seat hole 221. The rotating seat hole 221 is fitted on the outer side of the central shaft 230, and the countersunk hole 225 is rotatably connected to the shoulder 232. A radial rotating seat screw hole 222 is provided at the lower part of the rotating seat 220. A third bolt 2503 is threaded in the rotating seat screw hole 222. A third spring 2603 and a third steel ball 2703 are provided inside the rotating seat screw hole 222. The third steel ball 2703 is stuck in one of the shaft segment grooves 234. The third bolt 2503 pushes against the third spring 2603, and the third spring 2603 pushes the third steel ball 2703 in the shaft segment groove 234.
[0045] The third spring 2603 and the third steel ball 2703 coupled between the rotary seat 220 and the central shaft 230 have the same function as the first spring 2601 and the first steel ball 2701 coupled between the adjusting seat 210 and the central shaft 230. They enable the rotary seat 220 to rotate around the central shaft 230 and keep the radial positions of the rotary seat 220 and the central shaft 230 relatively fixed. The rotary seat 220, which rotates around the central shaft 230, can make each of the surgeon's arms tilt back and forth to meet the needs of the surgeon.
[0046] refer to Figures 6 to 12 The upper part of the rotary seat 220 is provided with a rotary seat shaft 223. The cylindrical surface of the rotary seat shaft 223 is provided with a set of evenly distributed rotary seat shaft grooves 224. The lower part of the support seat 240 is provided with a bearing seat bushing 241. The cylindrical surface of the bearing seat bushing 241 is provided with a radial bearing seat screw hole 242. The bearing seat screw hole 242 is threaded with a second bolt 2502. The bearing seat screw hole 242 is provided with a second spring 2602 and a second steel ball 2702. The second steel ball 2702 is stuck in one of the rotary seat shaft grooves 224. The second bolt 2502 pushes against the second spring 2602. The second spring 2602 pushes the second steel ball 2702 into the rotary seat shaft groove 224.
[0047] The second spring 2602 and the second steel ball 2702 coupled between the rotary seat 220 and the support seat 240 have the same function as the first spring 2601 and the first steel ball 2701 coupled between the adjusting seat 210 and the central shaft 230: they allow the support seat 240 to rotate around the rotary seat 220 and keep the radial positions of the support seat 240 and the central shaft 230 relatively fixed. The support seat 240, which rotates around the rotary seat 220, can adjust the inward and outward tilt angles of each of the surgeon's arms to meet the needs of the surgeon.
[0048] When using this device, the doctor places both arms on the support base 240. During the operation, the position of the two arms can be adjusted as needed. The motor 170 is started, and when the motor 170 rotates, it drives the lead screws 130 on both sides to rotate. The lead screws 130 drive the upper adjustment device 200 to move up and down through the lifting rod 120, so as to adjust the height of the doctor's arms.
[0049] When each support seat 240 is pushed axially to the left and right, the first steel ball 2701 between the adjusting seat 210 and the central shaft 230 will sequentially change position in the axial groove 231, thereby achieving the purpose of adjusting the left and right position of the adjusting device 200, so that the doctor can freely adjust the left and right position of each arm. When the support seat 240 is stopped, the adjusting device 200 is fixed in the current position under the action of the first spring 2601 and the first steel ball 2701.
[0050] Pressing the rear side of the support seat 240 downwards causes the support seat 240 to rotate around the central axis 230. The third steel ball 2703 between the rotating seat 220 and the central axis 230 will change position in the shaft groove 234 in sequence, causing a certain degree of tilt in the doctor's arm. When the rotation of the support seat 240 stops, the adjustment device 200 is fixed in the current position under the action of the third spring 2603 and the third steel ball 2703.
[0051] Pushing the rear side of the support seat 240 left and right causes the support seat 240 to rotate around the axis of the rotating seat shaft 223. The second steel ball 2702 between the rotating seat 220 and the support seat 240 will change position in turn in the rotating seat shaft groove 224, which can adjust the inward and outward tilt angle of each of the doctor's arms. When the rotation of the support seat 240 is stopped, the adjustment device 200 is fixed in the current position under the action of the third spring 2603 and the third steel ball 2703.
[0052] The above features allow the doctor's arm height, left and right, front and back, and left and right angles to be adjusted. To adjust, simply move the support 240 in the corresponding direction.
[0053] The adjusting seat 210, rotating seat 220, central shaft 230, and support seat 240 are occasionally connected by springs and steel balls. The left and right position, forward and backward tilt, and left and right tilt of the doctor's arm can all be adjusted. During adjustment, simply move the support seat 240 in the corresponding direction. The occasionally rotating parts connected by springs and steel balls have the following functions: First, the position between the rotating parts coupled by springs and steel balls can be freely adjusted. Second, the position between the rotating parts coupled by springs and steel balls is relatively fixed during surgery. Third, it avoids the problem of the rotating parts being unable to be adjusted or fixed when the fastener fails, which is common with traditional fastener connections. The rotating bolt can adjust the preload of the spring to ensure the relative fixation of the axial position between the rotating parts.
