Description

Technical Field

[0001] The invention relates to a Chinese medicine splint bending and forming device based on distal radius fracture and a working method. Background Art

[0002] In traditional Chinese medicine theory, the fixation method for distal radius fractures of the arm mainly focuses on harmonizing qi and blood, promoting healing, and combining external fixation techniques. As early as in the Yellow Emperor's Classic of Internal Medicine and Treatise on Febrile Diseases, there were records of methods and principles for fracture treatment. Traditional fixation devices may include wooden boards, bamboo strips, bandages, etc. Compared with the metal splints used in modern medicine, the materials and structures are simpler, but the basic principles of fixation and support are the same. Traditional Chinese medicine splints are usually made of wooden boards, plastic boards or other hard materials.

[0003] Distal radius fracture is the most common type of fracture in orthopedics, accounting for 17%-20% of all fractures in the human body. Manual closed reduction combined with traditional splint or plaster external fixation is the main conservative treatment method. Compared with plaster external fixation, traditional splint external fixation has the advantages of good breathability, light weight, and dynamic adjustment of tightness, so it is relatively more commonly used in clinical practice. The purpose of splint fixation is to keep the fracture end from shifting and limit the movement of the fracture site and its adjacent joints. The fixation should be firm but not tight to avoid compression of blood circulation and nerves.

[0004] However, the current medical splints are relatively simple in size, usually only in large, medium and small sizes, which are difficult to adapt to the individual differences in wrist and arm width of different patients, resulting in less than ideal fixation effect. Therefore, if the condition of distal radius fracture can be taken into consideration, a personalized Chinese medicine wooden splint can be made according to the individual differences in wrist and arm width of different patients, which will significantly improve the fixation effect.

It should be noted that the hand-cranked linear slide module (also called handwheel linear module) is an existing mature product, and the peripheral side of the driving hand wheel is provided with scales for quantitatively controlling the displacement of the slide, which are all existing technologies, and its specific structure and working principle will not be repeated here. The specific model of the hand-cranked linear slide module can be selected according to the required movement stroke of the slide.

The structures of the first pair of forming movable members 35, the second pair of forming movable members 36, and the fourth pair of forming movable members 30 are exactly the same, and the structure of the third pair of forming movable members 37 is only different in the specific shape of the forming movable seat from the shape of the forming movable seat of the first pair of forming movable members 35, and the third pair of forming movable members 37 corresponds to the position where the forming wooden board needs to be bent. The heating assembly is arranged inside the forming movable seat 9 of the third pair of forming movable members 29, which is close to one end of the forming wooden board 5.

[0026] In this embodiment, the heating assembly includes three heating rods 13 distributed in a circle, and a temperature sensor 12 arranged inside the three heating rods 13. The three heating rods are installed inside the forming movable seat, and two terminals are led out from the top of each heating rod 13. The terminals of the three heating rods 13 are connected in parallel with the temperature control system, and one terminal is led out from the top of the temperature sensor 12 to connect with the temperature control system. Specifically: the forming movable seat of the third pair of forming movable parts is provided with three through holes with a diameter of 6 mm at one end close to the forming wooden board for embedding the heating rods, and a threaded hole with a depth of 20 mm and a diameter of 6 mm is provided in the middle of the three through holes for connecting the temperature sensor.

[0027] In this embodiment, the fixing assembly includes a limit block 3, a fixed block 6 and a sliding block 8 arranged on the right side of the limit block 3.

During operation, when the push-pull type quick clamp is tightened backward, the push-pull type quick clamp pushes the sliding block to move backward (that is, to move toward the side where the forming wood board is located) through the adjusting bolt, and the sliding protrusion at the left end of the bottom of the sliding block slides along the longitudinal groove, and the sliding block also slides with the guide bolt through the longitudinal long hole to achieve the guiding effect of the longitudinal movement of the sliding block.

[0029] In this embodiment, a spring 2 that is telescopic in the longitudinal direction is provided on the left side of the sliding block 8, the front end of the spring 2 is connected to a first spring fixing bolt 34 vertically fixed on the bottom plate 1, and the rear end of the spring 2 is connected to a second spring fixing bolt 15 fixed on the left end of the sliding block 8. When the sliding block moves backward under the push of the push-pull type quick clamp until it contacts the forming wood board, the spring is in a stretched state; after the bending forming is completed, the push-pull type quick clamp is pulled forward to release, and the push-pull type quick clamp is separated from the sliding block, and at this time, the sliding block moves forward to reset under the pull of the spring elastic force.

The heating rod 13 adjusts the temperature according to the instructions of the controller 28 to keep it within the preset range; the display is used to display the real-time situation of the ambient temperature and the parameters set by the controller.

There are multiple limit block fixing holes 22 that are evenly spaced in the lateral direction. Two through holes with a diameter of 5 mm are provided in the limit block 3. The lateral position of the forming wood board 5 can be controlled by selecting different limit block fixing holes 22 on the base plate 1 through bolts.

[0032] In this embodiment, the working method of the TCM splint bending and forming device based on distal radius fracture comprises the following steps: Step 1: Fix the limit block 3 on the bottom plate 1; Step 2: Place the forming wooden board 5 on the bottom plate 1 in a horizontal vertical position, with the left end of the forming wooden board 5 contacting the limiting block 3 and the rear side of the forming wooden board 5 contacting the fixing block 6; Step 3: Adjust the adjusting bolt 14 at the rear end of the push-pull quick clamp 7 so that the end of its nut contacts the sliding block 8; Step 4: Pull the push-pull quick clamp 7 backward to push the sliding block 8 to move backward. The sliding block 8 cooperates with the fixing block 6 to clamp the forming wooden board 5 from the front and rear directions to fix the forming wooden board 5 on the bottom plate 1; Step 5: Turn on the power switch 27 of the temperature control system, set the upper and lower temperature limits, and observe the display 29 to wait for the heating rod 13 to heat to the preset temperature; Step 6: Rotate the driving handwheel 16 in each linear slide module 10 to gradually move the forming moving seat 9 of each forming moving member to push the forming wooden board 5 to bend. When the forming wooden board 5 is bent to a suitable angle, the driving handwheel is no longer rotated, and the forming wooden board 5 is left to bend under the dual effects of force and temperature. Step 7: Turn off the power switch 27 of the temperature control system, rotate the driving handwheel 16 in each linear slide module 10 to reset the forming movable seat 9 of each forming movable part, pull back the push-pull quick clamp 7, reset the sliding block 8, and take out the forming wooden board 5 to obtain the required Chinese medical wooden splint.
