Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an auxiliary bracket for lithotomy position examination. Background Technology

[0002] The lithotomy position is the most commonly used position for anal surgery. The patient lies supine on the examination bed with their buttocks close to the edge and their legs placed on leg supports. This position maximizes perineal exposure and is commonly used for rectal and anal canal surgeries as well as gynecological examinations. Currently, lithotomy position beds typically have the leg supports installed later. After installation, the height and length are adjusted before the legs are placed on the supports. However, due to inherent errors in manual visual inspection and adjustment, pre-adjustment often fails to achieve the correct posture on the first attempt. Furthermore, the leg opening angle cannot be adjusted during treatment. If the patient experiences leg discomfort (e.g., excessive leg opening) or insufficient leg opening during treatment, adjustments cannot be made promptly, hindering the treatment process. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a lithotomy position examination auxiliary bracket that is easy to operate and allows medical staff to adjust the patient's position at any time.

[0027] The present invention will be further described below through specific embodiments.

[0028] like Figures 1 to 7 As shown, this embodiment provides an auxiliary support bracket for stone cutting position examination, including a bed 1, two leg steering adjustment devices 2, and two pull cable devices 3.

[0029] The bed 1 allows the patient to lie supine and includes a sponge air cushion 11 at the top of the bed 1 and a movable seat 12 at the bottom of it. The patient can lie on the sponge air cushion 11 to improve the patient's comfort during the examination. Specifically, the movable seat 12 is equipped with multiple casters 13 with brakes to facilitate the movement of the lithotomy position examination auxiliary bracket by medical staff.

[0030] The leg turning adjustment device 2 is positioned opposite each other on both sides of the rear of the bed 1. It can rotate left and right and up and down respectively to adjust the height and distance between the patient's legs. The leg turning adjustment device 2 includes a turning bracket 21, a rotation limiting mechanism 22, and a leg support 23 movably mounted on the turning bracket 21. Specifically, the turning bracket 21 includes a fixed base 24 on the side of the bed 1, an adjusting vertical rod 25 rotatably connected to the fixed base 24 at one end, an adjusting horizontal rod 26 rotatably connected to the adjusting vertical rod 25 at one end, a first rotating assembly 27 positioned between the fixed base 24 and the adjusting vertical rod 25, and a second rotating assembly 28 positioned between the adjusting vertical rod 25 and the adjusting horizontal rod 26. The rotating assembly 27 is used to adjust the vertical rod 25 to rotate left and right relative to the fixed seat 24, that is, to adjust the distance between the patient's legs. The second rotating assembly 28 is used to adjust the horizontal rod 26 to rotate up and down relative to the vertical rod 25, that is, to adjust the height of the patient's legs. Further, the rotation limiting mechanism 22 includes a first limiting assembly 221 and a second limiting assembly 222 respectively disposed in the first rotating assembly 27 and the second rotating assembly 28 to limit the rotation of the vertical rod 25 and the horizontal rod 26. The first limiting assembly 221 is used to fix the position between the vertical rod 25 and the fixed seat 24, and the second limiting assembly 222 is used to adjust the position between the horizontal rod 26 and the vertical rod 25.

[0031] Two pull-wire devices 3 are respectively mounted on two steering brackets 21. Each pull-wire device 3 includes a pull-wire handle 31 located at the front end of the adjusting crossbar 26, a first pull wire 32 and a second pull wire 33 respectively connecting the pull-wire handle 31 to the first limiting component 221 and the pull-wire handle 31 to the second limiting component 222. The first pull wire 32 and the second pull wire 33 are simultaneously tightened through the pull-wire handle 31, causing the adjusting vertical rod 25 to rotate left and right around the axis of the first rotating component 27, and the adjusting crossbar 26 to rotate up and down around the axis of the second rotating component 28. This allows for simultaneous adjustment of the distance between the patient's legs and the height of their legs, fixing the patient's legs in a position convenient for examination. This enables rapid adjustment of the patient's position, reduces the workload of medical staff, and improves examination efficiency. Specifically, the pull-wire handle 31 includes a pull-wire handle 31 located at the front end of the adjusting crossbar 26. The adjustable crossbar 26 has a fixed section 34 at its front end and an elastic section 35 that can move closer to or further away from the fixed section 34. The first pull wire 32 and the second pull wire 33 are respectively connected to the elastic section 35. The steering bracket 21 is provided with a pull wire channel 36 for the first pull wire 32 and the second pull wire 33 to pass through. In use, medical staff can tighten or loosen the elastic section 35 to make the first pull wire 32 and the second pull wire 33 control the usage state of the corresponding first limit component 221 and the second limit component 222, thereby adjusting the distance and height of the two steering brackets 21, and thus adjusting the opening angle of the patient's legs, so that the patient's position is suitable for lithotomy examination. Medical staff can adjust the patient's position at any time during the examination. Furthermore, the first pull wire 32 and the second pull wire 33 can be made of steel wire, which is not easy to break.

[0032] The first rotating assembly 27 includes a first rotating seat 271 with its opening facing upward, mounted on a fixed base 24; a second rotating seat 272 with its opening facing downward, mounted at the lower end of an adjusting vertical rod 25; and a first positioning member 273 positioned between the first rotating seat 271 and the second rotating seat 272. The second rotating seat 272 can rotate left and right relative to the first rotating seat 271. Further, the first positioning member 273 includes a protrusion 274 extending outward from the outer periphery of the first rotating seat 271 and a positioning sleeve 275 that can be nested around the outer periphery of the second rotating seat 272 and connected to the protrusion 274. The first rotating seat 271, the positioning sleeve 275, and the second rotating seat 272 are coaxially arranged. In use, the first... The second rotating seat 272 rotates left and right within the positioning sleeve 275. The protrusion 274 and the positioning sleeve 275 are detachably connected by the positioning bolt 276 and the positioning nut 277. Through the cooperation of the positioning sleeve 275, the positioning bolt 276 and the positioning nut 277, the first rotating seat 271 and the second rotating seat 272 are axially opposite each other, which serves to position the axis and prevent the axis of rotation of the adjusting vertical rod 25 from shifting during rotation. Furthermore, the fixed seat 24 includes a fixed part 241 disposed on one side of the bed body 1 and a fixed rod 242 vertically disposed on the fixed part 241. The first rotating seat 271 is disposed on the upper end of the fixed rod 242.

[0033] The second rotating assembly 28 includes a third rotating seat 281 with its opening facing the side at the upper end of the adjusting vertical rod 25, a fourth rotating seat 282 with its opening at the rear end of the adjusting horizontal rod 26 opposite to the third rotating seat 281, and a second positioning member 283 disposed between the third rotating seat 281 and the fourth rotating seat 282. The fourth rotating seat 282 can rotate up and down relative to the third rotating seat 281. The third rotating seat 281, the fourth rotating seat 282, and the second positioning member 283 are coaxially arranged. In use, the fourth rotating seat 282 and the second positioning member 283 rotate around the third rotating seat 281. 81 rotates up and down; specifically, the second positioning member 283 keeps the axes of the third rotating seat 281 and the fourth rotating seat 282 relatively set, which plays the role of positioning the axis and preventing the axis of rotation of the adjusting crossbar 26 from shifting during the rotation process; furthermore, the second positioning member 283 is the same as the first positioning member 273, and its cooperation with the third rotating seat 281 and the fourth rotating seat 282 is consistent with the cooperation with the first positioning member 273 and the first rotating seat 271 and the second rotating seat 272. The specific structure and cooperation method will not be described in detail here.

[0034] The first limiting component 221 includes a first serrated portion 223 extending upward from the inner bottom surface of the first rotating seat 271, a second serrated portion 224 movably disposed inside the second rotating seat 272 and meshing with the first serrated portion 223, and a return spring 225 connecting the second rotating seat 272 and the second serrated portion 224. The second serrated portion 224 is connected to a first pull wire 32. When the first pull wire 32 is tightened, the second serrated portion 224 moves away from the first serrated portion 223, causing the second rotating seat 272 to rotate left and right relative to the fixed seat 24 within the positioning sleeve 275. At this time, the return spring 225 is pressed down. Specifically, when the adjusting rod 25 is adjusted to a suitable position, the first pull wire 32 is released, the return spring 225 returns to its original position, and drives the second serrated portion 224 to move away from the first serrated portion 223. The second sawtooth portion 224 moves closer to the first sawtooth portion 223, so that it is fixedly engaged with the first sawtooth portion 223. At this time, the position of the adjusting rod 25 is fixed and cannot rotate left or right relative to the fixed seat 24. Furthermore, the first limiting component 221 also includes a guide member 226 disposed between the second sawtooth portion 224 and the second rotating seat 272. The guide member 226 includes a plurality of guide blocks 227 spaced apart along the outer periphery of the second sawtooth portion 224 and a plurality of guide grooves 228 disposed on the inner wall of the second rotating seat 272, which can move back and forth relative to the guide blocks 227. By the cooperation of the plurality of guide blocks 227 and the plurality of guide grooves 228, the movement direction of the second sawtooth portion 224 is restricted, which can prevent the position of the second sawtooth portion 224 from shifting and not engaging with the first sawtooth portion 223.

[0035] The second limiting component 222 is the same as the first limiting component 221. Its cooperation with the third rotating seat 281 and the fourth rotating seat 282 is the same as that with the first limiting component 221 and the first rotating seat 271 and the second rotating seat 272. Its specific structure and cooperation method will not be described in detail here.

[0036] The leg support 23 includes an elastic clamp 231 detachably mounted on an adjusting crossbar 26 and a leg rest 232 rotatably connected to the elastic clamp 231. In use, the leg rest 232 is fixed to the outer side of the lower leg and foot to prevent pressure on the popliteal fossa. When the steering support 21 is rotated, the leg rest 232 rotates freely relative to the elastic clamp 231 to adjust the flexion and extension state of the patient's lower leg, improving patient comfort. Specifically, the leg rest 232 includes multiple adjustable fixing straps 233 spaced along its length and multiple ventilation holes 234 on the side of the leg rest 232. Ventilation holes 234 improve the breathability of the leg support 232. Furthermore, the elastic clamp 231 is detachably mounted on the adjusting crossbar 26 by means of fixing bolts 235 and fixing nuts 236. When the fixing bolts 235 and fixing nuts 236 are fixed on the elastic clamp 231, the elastic clamp 231 is fixed on the adjusting crossbar 26 and cannot move back and forth relative to the adjusting crossbar 26. Furthermore, the adjustable fixing strap 233 is an existing structure that can adjust the length to fix the patient's lower leg and foot in the leg support 232. Its specific structure and the principle of adjustment of the telescopic length will not be described in detail here.

[0037] During the examination, the patient lies on bed 1. First, based on the position of the patient's legs, the leg supports 23 are installed on the two opposing adjusting crossbars 26 using elastic clamps 231, fixing bolts 235, and fixing nuts 236. Multiple adjustable fixing straps 233 are then adjusted so that the leg supports 232 are worn on the patient's lower legs and the outer sides of the feet. Then, using the leg steering adjustment device 2 and the two pull-wire devices 3, the medical staff holds the two elastic segments 35, and the opposing first pull wire 32 and second pull wire 33 are tightened, respectively causing the first limiting component 221 to disengage from the first rotating seat 271 and the second limiting component 222 to disengage from the third rotating seat 281. Simultaneously, the vertical rod 25 can be controlled to rotate left and right relative to the fixed seat 24, and the horizontal rod 26 can be controlled to rotate up and down relative to the vertical rod 25. After adjusting the patient's leg opening distance and leg elevation to a suitable position, the elastic section 35 is released. The first pull line 32 and the second pull line 33 return to their original positions under the action of the first limiting component 221 and the second limiting component 222, so that the vertical rod 25 is fixedly connected to the fixed seat 24 and the horizontal rod 26, thereby fixing the opening angle of the patient's legs. This allows the patient's position to be adjusted to a suitable position for examination. The operation is simple, and medical staff can adjust the patient's position at any time.

[0038] In summary, by utilizing the above-mentioned technical solution of this utility model, through the cooperation of the bed body 1, the two leg turning adjustment devices 2 respectively arranged on both sides of the tail of the bed body 1, and the two pull wire devices 3 respectively arranged on the two turning brackets 21, the patient's position can be quickly adjusted, saving the workload of medical staff and improving examination efficiency. In addition, by defining the specific structure of the turning bracket 21, the first rotating component 27 is used to adjust the left and right rotation of the adjusting vertical rod 25 relative to the fixed seat 24, that is, to adjust the opening distance of the patient's two legs, and the second rotating component 28 is used to adjust the up and down rotation of the adjusting horizontal rod 26 relative to the adjusting vertical rod 25, that is, to adjust the height of the patient's legs. In addition, by defining the specific structure of the limiting rotation mechanism 22, the first limiting component 221 is used to fix the position between the adjusting vertical rod 25 and the fixed seat 24, and the second limiting component 222 is used to adjust the position between the adjusting horizontal rod 26 and the adjusting vertical rod 25.

[0039] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model application and the contents of the specification should still fall within the scope of the present utility model application.
