Technical Field
[0001] This utility model relates to the field of activity device technology, and in particular to a passive flexion and extension activity device for the lower limbs after liver, gallbladder and pancreas surgery. Background Technology
[0002] Hepatobiliary and pancreatic surgery is a surgical treatment for diseases of the liver, biliary system, and pancreas. The passive flexion and extension device for the lower limbs used after hepatobiliary and pancreatic surgery is a medical rehabilitation device. It is mainly used to help postoperative patients (especially those who are bedridden for a long time or have limited mobility) to perform passive movements of the lower limb joints to prevent complications such as deep vein thrombosis (DVT), muscle atrophy, and joint stiffness. Existing passive flexion and extension devices for lower limbs after hepatobiliary and pancreatic surgery can generally only be used after the patient has stood up. However, some patients may be unable to stand up due to lumbar spine diseases or other reasons, making it impossible to use the passive flexion and extension devices for lower limbs after hepatobiliary and pancreatic surgery normally. Therefore, we propose a passive flexion and extension device for lower limbs after hepatobiliary and pancreatic surgery. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies. Currently available passive flexion and extension devices for lower limbs after liver, gallbladder, and pancreas surgery can generally only be used after the patient has stood up. However, some patients may be unable to stand up due to lumbar spine diseases or other reasons, which prevents the passive flexion and extension devices for lower limbs after liver, gallbladder, and pancreas surgery from being used normally.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A passive flexion and extension device for the lower limbs after hepatobiliary and pancreatic surgery includes a base plate.

[0026] like Figure 1-4 As shown, this utility model provides a technical solution: a passive flexion and extension device for the lower limbs after hepatobiliary and pancreatic surgery, including a base plate 1. A linear guide rail 2 is provided at the top of the base plate 1. A lead screw 201 is rotatably connected inside the linear guide rail 2. A drive motor 202 is installed on the front of the linear guide rail 2 corresponding to the lead screw 201. A slider 203 is sleeved around the lead screw 201 and inside the linear guide rail 2. The drive motor 202 can drive the lead screw 201 to rotate, so that the slider 203 can be displaced. A first sleeve 3 is rotatably connected to the top of the base plate 1 near the back. The top of 203 is rotatably connected to a second sleeve 4. A rotating seat 301 is installed on the side of the first sleeve 3 corresponding to the bottom of the second sleeve 4. A connecting rod 401 is installed on the side of the second sleeve 4 corresponding to the first sleeve 3 and close to the rotating seat 301. A rotating column 402 is installed on the outer wall of the connecting rod 401 corresponding to the rotating seat 301. A rotating groove 302 is opened on the outer wall of the rotating seat 301 corresponding to the rotating column 402. The rotating column 402 can rotate inside the rotating groove 302 to finely adjust the angle between the first sleeve 3 and the second sleeve 4. Example
[0027] like Figure 1-4 As shown, an anti-slip pad 101 is glued and fixed to the bottom of the base plate 1. The anti-slip pad 101 is made of rubber. The anti-slip pad 101 made of rubber prevents the base plate 1 from easily shifting its position when placed on the hospital bed, making it more stable during use.
[0028] The output end of the drive motor 202 extends into the interior of the linear guide rail 2 and is fixedly connected to the lead screw 201. By extending the output end of the drive motor 202 into the interior of the linear guide rail 2 and being fixedly connected to the lead screw 201, the drive motor 202 can drive the lead screw 201 to rotate inside the linear guide rail 2 after it is turned on.
[0029] The slider 203 is slidably connected to the linear guide rail 2 and threadedly intersecting with the lead screw 201. Through the sliding connection between the slider 203 and the linear guide rail 2 and the threaded intersection with the lead screw 201, the lead screw 201 can drive the slider 203 to move inside the linear guide rail 2 while rotating.
[0030] Both the first sleeve 3 and the second sleeve 4 are designed to be opened. Both the first sleeve 3 and the second sleeve 4 are made of polyethylene. The openable design of the first sleeve 3 and the second sleeve 4 makes it more convenient for patients to use. The first sleeve 3 and the second sleeve 4 made of polyethylene have a more stable structure and a longer service life.
[0031] The rotating column 402 is adapted to the rotating groove 302 and the rotating column 402 is rotatably connected to the rotating groove 302. Through the rotatable connection between the rotating column 402 and the rotating groove 302, when the slider 203 drives the second sleeve 4 to move, the second sleeve 4 can drive the connecting rod 401 and the rotating column 402 to move together, so as to cooperate with the rotating seat 301 to drive the first sleeve 3 to change the angle.
[0032] A telescopic protective cover 5 is installed near the top between the first sleeve 3 and the second sleeve 4. The design of the telescopic protective cover 5 can protect the patient's legs.
[0033] A deformable soft pad 6 is fixed near the bottom between the first sleeve 3 and the second sleeve 4. The deformable soft pad 6 is made of silicone. The deformable soft pad 6 made of silicone can not only deform well, but also has a comfortable surface feel and will not cause the patient to feel the sensation of a foreign object bumping.
[0034] The working process of this utility model is as follows: When using a passive flexion and extension device for the lower limbs after hepatobiliary and pancreatic surgery, medical staff first need to place the base plate 1 on the hospital bed. At this time, the first sleeve 3 and the second sleeve 4 can be opened, and the patient's lower limbs are placed inside the first sleeve 3 and the second sleeve 4. The drive motor 202 is then turned on, causing the drive motor 202 to drive the lead screw 201 to rotate. When the lead screw 201 rotates, it will drive the slider 203 and the second sleeve 4 to move together. While the second sleeve 4 is moving, it can drive the connecting rod 401 and the rotating column to move together. 402 is displaced together to coordinate with the rotating groove 302 and the rotating seat 301 to change the angle of the first sleeve 3. When the slider 203 is displaced to the end of the linear guide rail 2, the rotation direction of the output end of the drive motor 202 can be reversed to perform reciprocating motion, so that the patient can exercise without getting up. Compared with the existing passive flexion and extension device for lower limbs after liver, gallbladder and pancreas surgery, it can not only more conveniently exercise the patient's lower limbs, but also can be used for patients who cannot get up due to lumbar spine diseases, etc., making it more practical.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
