[0002] In medical treatment, when treating fractures, trauma and other diseases, it is generally necessary to use a support plate with a certain hardness to fix the affected area, help keep the injured area stable, prevent further damage, and assist the patient's recovery. In order to facilitate the fixation of the support plate to the affected area, it needs to be machined.

[0003] Since medical device support plates have various shapes and sizes depending on the injured part, and most support plates are made of materials with a certain toughness for the patient's consideration, they may break and deform when the clamping force is large. In the existing technology, the types of machining jigs are relatively single. When faced with support plates that are mostly curved or even need to be specially designed according to the affected area, the fixture fixing effect is poor, and processing errors are prone to occur during the machining process of the support plates.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-6 A medical device support plate positioning machining jig includes: a base 1, a bottom mounting plate 2 is installed at the bottom of the base 1, and support feet 5 are installed at the four corners of the bottom of the bottom mounting plate 2. A constant pressure mechanism 3 is installed on the side of the base 1, and multiple groups of bottom support mechanisms 4 are provided on the base 1. The support plate is placed on the bottom support mechanism 4 for processing, and a positioning mechanism 6 is provided inside the base 1.

[0025] Among them; the positioning mechanism 6 includes a positioning plate 61, which is slidably arranged inside the base 1, and a screw 62 is installed at the front end of the positioning plate 61. The end of the screw 62 passes through the base 1 and is threadedly sleeved with a positioning handle 63 on the surface. By utilizing the rotating ability of the positioning handle 63, the screw 62 is pulled to make the positioning plate 61 move forward and cooperate with the base 1 to fix the bottom support mechanism 4.

[0026] Among them, the positioning plate 61 is provided with a receiving groove 7 at the front end near both sides, and a spring 8 is provided inside the receiving groove 7. The end of the spring 8 is overlapped on the inner wall of the base 1. After the support plate is processed, the positioning handle 63 is rotated in the opposite direction. Under the action of the spring 8, the positioning plate 61 will automatically slide backward without manual pushing, thereby loosening the bottom support mechanism 4.

[0027] Among them, a plurality of groups of through first through holes 9 are provided on the base 1, and a first clip 10 is installed in each group of first through holes 9, which spans the internal space of the base 1. The first clip 10 cooperates with the first through hole 9 to form a circular hole, so that the bottom support mechanism 4 can only slide up and down without shaking. In addition, the first clip 10 is used to give a certain friction force to the inner wall of one side of the first through hole 9, which is convenient for clamping the bottom support mechanism 4.

[0028] Among them, the surface of the positioning mechanism 6 is provided with multiple groups of second through holes 13, and the position of each group of second through holes 13 corresponds to the position of each group of first through holes 9, and the bottom support mechanism 4 is arranged in a through-type manner in the first through hole 9 and the second through hole 13. The inner wall of the second through hole 13 is installed with a second clip 14, and the position of the second clip 14 corresponds to the position of the first clip 10. The first clip 10 vertically spans the middle section of the internal space of the base 1 and passes through the second through hole 13 and is slidably arranged with its inner wall. The second clip 14 is centered on the center of the first through hole 9 and is centrally symmetrical with the first clip 10. When the positioning mechanism 6 moves, it can cooperate with the first clip 10 to apply friction to both sides of the bottom support mechanism 4 to achieve a fixing effect.

[0029] Among them, slide bars 11 are installed on both sides of the inner wall of the base 1, and slide rails 12 are opened on the side of the positioning mechanism 6. The slide bar 11 is slidably set in the inner wall of the slide rail 12. By setting the slide bar 11 and the slide rail 12, the forward and backward sliding ability of the positioning mechanism 6 is increased, so that the elastic force of the spring 8 is sufficient to push the positioning mechanism 6 to slide.

[0030] Among them; the bottom support mechanism 4 includes a slide rod 41, the top of the slide rod 41 is located above the base 1 and is installed with a rubber fulcrum 42, the bottom of the slide rod 41 is located below the base 1 and is installed with a bottom pull plate 43, and the sliding sleeve on the slide rod 41 is provided with an upper pull ring 45, the upper pull ring 45 is installed on the bottom mounting plate 2, the upper pull ring 45 and the bottom pull plate 43 are connected by setting a tension spring 44, and the tension spring 44 is sleeved on the slide rod 41. By setting the tension spring 44, the bottom support mechanism 4 has a certain degree of compression and rebound capabilities, and then after the support plate is placed, it can change height according to the contact position, so that the bottom of the support plate is fitted with multiple contact points, thereby improving the fixing effect after clamping.

[0031] Among them, the fixed pressure mechanism 3 includes a bracket 31, the bottom of the bracket 31 is fixed to the side of the base 1 through a mounting seat, the top of the bracket 31 is installed with a rail 32, the internal sliding sleeve of the rail 32 is provided with a support rod 35, the top of the rail 32 is integrally provided with a fastening seat 33 with a sliding cavity, the fastening seat 33 is screwed with a knob 34, the bottom of the knob 34 is located in the sliding cavity of the fastening seat 33 and overlapped on the support rod 35, the end of the support rod 35 is integrally provided with an inner screw sleeve 36, the internal threaded sleeve of the inner screw sleeve 36 is provided with a screw rod 37, the top of the screw rod 37 is installed with a screw cap 38, and the bottom of the screw rod 37 is rotatably provided with a pressing plate 39, the fixed pressure mechanism 3 is used to apply pressure from above to the support plate to be processed, and cooperates with the bottom support mechanism 4 to complete the positioning and clamping effect. At the same time, the fixed pressure mechanism 3 can adjust the clamping position to a certain extent according to the different fixing points of the support plate.

[0032] Working principle: when it is necessary to perform positioning machining on the support plate of medical equipment, first place the jig on the processing table, then place the support plate on the top of the bottom support mechanism 4, move the constant pressure mechanism 3 to the top of the support plate and fix it, apply a certain pressure to the support plate, so that the bottom support mechanism 4 at the bottom of the support plate changes its height according to the fitting position, and after the bottom support mechanism 4 fits the support plate at multiple contact points, use the moving ability of the positioning mechanism 6 to cooperate with the base 1 to fix all the bottom support mechanisms 4 at once, so that the bottom support mechanism 4 has sufficient supporting capacity to cooperate with the constant pressure mechanism 3 to clamp the support plate, so that the support plate can be machined.
