Technical Field

[0001] This utility model relates to the field of orthopedic medical device technology, specifically a novel ring-bar combination quick-locking bar and bar needle clamp. Background Technology

[0002] Orthopedics is a specialized field of medicine that mainly involves the diagnosis, treatment, and rehabilitation of diseases of the musculoskeletal system, including bones, muscles, joints, and ligaments. In this field, doctors use various specialized surgical tools and instruments for treatment. In the medical field, when upper limb fractures, lower limb fractures, or bone malunion occur, angular deformities of the bone alignment are often present. Clinically, surgical treatment is required. After anatomical treatment, doctors also need to use orthopedic instruments to reposition the bones, such as using orthopedic ring-rod combination fixation frames, to help the bones recover and heal as quickly as possible.

[0003] Pin clamps and rod clamps are commonly used accessories for external fixation devices in orthopedic medical fields. However, the pin clamps and rod clamps currently popular on the market have limited functions and cannot meet the needs of some surgeries. This has caused a lot of trouble for clinicians during surgery and affected the quality and effect of the surgery. Therefore, this utility model provides a new type of ring-rod combination quick-lock rod and pin clamp. Utility Model Content

[0004] The purpose of this invention is to provide a novel combination of ring bar and quick-locking bar and pin clamp to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel ring bar combination quick-locking bar and pin clamp, comprising multiple pin clamps and an mounting rod. Each pin clamp comprises two connecting blocks, each connecting block having an arc-shaped groove at both ends and a through hole for the mounting rod to pass through. The mounting rod comprises an upper rod and a lower rod, the lower rod being detachably connected to the bottom of the upper rod. A circular baffle is fixedly connected to the outer surface of the lower rod, and a fixing block is fixedly connected to the top of the upper rod. A cam is rotatably connected to the fixing block.

[0006] Preferably, a connecting bolt is fixedly connected to the top of the lower rod, and the connecting bolt is threaded to the bottom of the upper rod. By rotating the lower rod, the lower rod is installed at the bottom of the upper rod under the action of the connecting bolt.

[0007] Preferably, a rotating rod is rotatably connected inside the fixed block, and the cam is installed at one end of the rotating rod. The rotating rod stabilizes the cam on the fixed block and allows it to rotate.

[0008] Preferably, both ends of the rotating rod are provided with cross grooves, and a cross slider is slidably connected inside the cross groove. The cam is fixedly connected to one end of the cross slider. Under the action of the cross groove and the cross slider, the cam slides horizontally back and forth at one end of the rotating rod.

[0009] Preferably, a limiting rod is provided on one side of the cam, and a limiting hole corresponding to the limiting rod is provided on the fixing block. The cam is pushed closer to the fixing block so that one end of the limiting rod is inserted into the limiting hole to limit the rotation of the cam.

[0010] Preferably, the top of the connecting block is provided with a limiting insertion hole, and a limiting post is fixedly connected to the top of the connecting block. The limiting post and the limiting insertion hole are symmetrically arranged about the through hole. Under the action of the limiting insertion hole and the limiting post, the two connecting blocks are prevented from being misaligned and rotated during the assembly process.

[0011] Preferably, a rotating cap is fixedly connected to the cam, and the longitudinal section of the rotating cap is a regular hexagon. The rotating cap facilitates the driving of the cam to rotate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This application uses the cam's protruding end and circular baffle to install multiple knitting needle clamps on the knitting needle clamp. The knitting needles are clamped and fixed by the combination of two arc-shaped grooves. The knitting needle clamp as a whole can rotate relative to the mounting rod, realizing multi-angle connection between the connecting rod and the metal bone needle to adapt to different needs.

[0014] 2. This application achieves rapid locking or unlocking of the knitting needle clamp by rotating the cam so that the cam's protruding end moves away from the needle clamp, thus completing the rapid installation and removal of the knitting needles.

[0015] 3. This application improves the stability of installation by limiting the relative rotation of the two connecting blocks after assembly through the setting of limit posts and limit sockets. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a novel ring bar combination quick-locking bar and needle clamp, including multiple needle clamps 1 and mounting rods 2. The needle clamp 1 is formed by combining two connecting blocks 11. Both ends of the connecting blocks 11 are provided with arc-shaped grooves. The needles are clamped by combining the two connecting blocks 11 and the two arc-shaped grooves. The size of the arc-shaped grooves can be manufactured according to the different sizes of needles. The top of the connecting block 11 is provided with a limiting insertion hole 13. The top of the connecting block 11 is fixedly connected with a limiting post 12. The limiting post 12 and the limiting insertion hole 13 are symmetrically arranged about the through hole. When the two connecting blocks 11 are docked, the limiting post 12 of one connecting block 11 is inserted into the limiting insertion hole 13 of the other connecting block 11 to limit the relative rotation between the two connecting blocks 11.

[0023] Please refer to it again. Figure 1 , Figure 2 and Figure 3The connecting block 11 has a through hole for the mounting rod 2 to pass through. The mounting rod 2 includes an upper mounting rod 21 and a lower mounting rod 22. The lower mounting rod 22 is detachably connected to the bottom of the upper mounting rod 21. A circular baffle 24 is fixedly connected to the outer surface of the lower mounting rod 22. A connecting bolt 23 is fixedly connected to the top of the lower mounting rod 22. The connecting bolt 23 is threaded to the bottom of the upper mounting rod 21. The assembled needle clamp 1 is inserted into the upper mounting rod 21, and then the connecting bolt 23 is screwed into the threaded hole at the bottom of the upper mounting rod 21 to complete the combination of the lower mounting rod 22 and the upper mounting rod 21. The circular baffle 24 supports and blocks the lowermost needle clamp 1. The upper mounting rod 21 and the lower mounting rod 22 have the same diameter. The needle clamp 1 can rotate relative to the mounting rod 2 to realize multi-angle connection between the connecting rod and the metal bone needle to adapt to different needs.

[0024] Please refer to it again. Figure 1 , Figure 2 and Figure 4 A fixing block 3 is fixedly connected to the top of the upper mounting rod 21. A cam 4 is rotatably connected to the fixing block 3. A rotating rod 31 is rotatably connected inside the fixing block 3. The cam 4 is installed at one end of the rotating rod 31. A rotating cap 5 is fixedly connected to the cam 4. The longitudinal section of the rotating cap 5 is a regular hexagon. The fixing block 3 and the circular baffle 24 block the multiple needle clips 1 installed on the mounting rod 2. Then, by rotating the cam 4, the protruding end of the cam 4 presses the upper needle clip 1 to make the multiple needle clips 1 stably combined together.

[0025] Please refer to it again. Figure 1 , Figure 2 and Figure 4 Both ends of the rotating rod 31 are provided with cross grooves, and a cross slider 32 is slidably connected inside the cross groove. The cam 4 is fixedly connected to one end of the cross slider 32. Under the action of the cross slider 32 and the cross groove, the cam 4 can slide back and forth on one side of the fixed block 3. A limiting rod 41 is provided on one side of the cam 4. A limiting hole 33 corresponding to the limiting rod 41 is provided on the fixed block 3. When the cam 4 protrudes downward, it pushes the cross slider 32 to slide into the cross groove, so that the limiting rod 41 on the cam 4 is inserted into the limiting hole 33 to limit the rotation of the cam 4. Conversely, it pulls the cam 4 away from the fixed block 3 so that the limiting rod 41 is pulled out from the limiting hole 33.

[0026] Working principle: Multiple connecting blocks 11 are sequentially passed through the bottom of the upper rod 21 and onto the upper rod 21. Then, under the action of the connecting bolt 23, the lower rod 22 is installed at the bottom of the upper rod 21. The circular baffle 24 supports and blocks the lowermost connecting block 11. The needle is placed into the two arc-shaped grooves. Then, by rotating the cam 4, the protruding end of the cam 4 presses the uppermost connecting block 11, so that the two arc-shaped grooves close and clamp the needle. Then, by pushing the cam 4 to slide closer to the fixed block 3, the rotation of the rotating rod 31 is restricted by inserting one end of the limiting rod 41 into the limiting hole 33.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
