Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical equipment technology, and in particular relates to a thoracic organ retractor. Background Technology
[0002] Retractors, also known as tissue retractors, are used to retract tissue and expose the surgical area, facilitating exploration and manipulation. They can be divided into handheld retractors and automatic retractors. They are available in various shapes and sizes, allowing for the selection of the appropriate retractor based on surgical needs.
[0003] Conventional thoracic retractors primarily adjust the spacing between hooks using a locking mechanism. However, the hooks require minimum adjustment based on the distance between the slots, resulting in insufficient adjustment precision in conventional thoracic retractors.
[0004] Therefore, we propose a thoracic organ retractor to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to solve the problem of insufficient adjustment accuracy of conventional thoracic organ retractors in the prior art, and to propose a thoracic organ retractor.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a thoracic organ retractor, comprising an adjusting latch, a fine-tuning frame, and a hook, wherein the adjusting latch is fixedly installed inside the hook, the adjusting latch is threadedly matched with the fine-tuning frame, and the hook is slidably installed on the outer end of the fine-tuning frame.
[0007] Loosen the adjusting lock to release it from the fine-tuning frame. Then, roughly adjust the hook, and then tighten the adjusting lock to connect it to the fine-tuning frame via the thread. Finally, fine-tune the adjustment using the fine-tuning frame. This method of first making a quick adjustment and then fine-tuning the adjustment using the fine-tuning frame ensures both adjustment speed and accuracy.
[0008] Preferably, the fine-tuning frame includes a threaded rod, a fixed base, a knob, a fixed hook, and a guide rod. The threaded rod is rotatably connected to the inner end of the fixed base and passes through the fixed base. The knob is fixedly connected to the outer end of the threaded rod and is in movable contact with the fixed base. The fixed hook is fixedly connected to the fixed base, and the guide rod is fixedly connected to the fixed base.
[0009] Turning the knob rotates the threaded rod, which in turn moves the adjusting latch. This causes the adjusting latch to slide along the threaded rod and guide rod, facilitating fine-tuning of the adjusting latch and hook.
[0010] Preferably, the fine-tuning frame further includes a limiting seat, which is fixedly connected to one end of the guide rod facing away from the fixed seat, and the threaded rod is rotatably installed on the inner end of the limiting seat.
[0011] By limiting the sliding limit of the hook along the threaded rod and guide rod with the limit seat, the hook is prevented from disengaging from the fine-tuning frame, thus improving the stability of the hook adjustment range.
[0012] Preferably, the hook includes a hook body, a slide block, and a buckle block, wherein the hook body is fixedly connected to the side end of the slide block, and the buckle block is fixedly connected to the upper end of the slide block.
[0013] The sliding block along the threaded rod and guide rod facilitates the adjustment of the distance between the hook body and the fixed hook.
[0014] Preferably, the hook further includes a magnet block, which is fixedly connected to the inner end of the buckle block.
[0015] The magnetic block allows for easy adjustment of the locking latch to maintain a locked state.
[0016] Preferably, the adjusting latch includes a rotating shaft, a handle, a guide seat, a slide rod, a tension spring, a threaded seat, an elliptical block, and an iron block. The handle slides through the rotating shaft, the slide rod slides through the guide seat, the tension spring is movably sleeved outside the slide rod, the slide rod is fixedly connected to the outer end of the threaded seat, one end of the tension spring is fixedly connected to the guide seat, the other end of the tension spring is fixedly connected to the threaded seat, and the elliptical block is fixedly connected to the lower part of the rotating shaft, and the elliptical block is in movable contact with the threaded seat.
[0017] Pull the handle in the opposite direction of the iron block to make the iron block and the magnet separate from the buckle. Then rotate the handle to drive the shaft, which will cause the elliptical block to loosen the threaded seat. Use the tension spring to move the threaded seat away from the threaded rod, thus unlocking the lock. Similarly, operate in the opposite direction to use the elliptical block to press the threaded seat against the outer end of the threaded rod, making it easy to switch between locking and unlocking the lock.
[0018] Preferably, the adjusting latch further includes a spherical block, which is fixedly connected to the end of the handle facing away from the iron block.
[0019] The spherical block increases the contact area between the outer end of the handle and the hand, thus facilitating hand protection.
[0020] In summary, the technical effects and advantages of this utility model are as follows: by releasing the adjusting lock, the adjusting lock is loosened from the fine-tuning frame, then the hook is roughly adjusted, and then the adjusting lock is tightened to make the adjusting lock threadedly connected to the fine-tuning frame, and then fine-tuned by the fine-tuning frame. This method of first quickly adjusting and then fine-tuning by the fine-tuning frame ensures both the adjustment speed and the adjustment accuracy.
[0021] 2. Turning the knob drives the threaded rod to rotate, which in turn moves the adjusting latch. This causes the adjusting latch to slide along the threaded rod and guide rod, facilitating fine-tuning of the adjusting latch and hook.
[0022] 3. Pull the handle in the opposite direction of the iron block to make the iron block and the magnet separate from the buckle. Then rotate the handle to drive the shaft, which will cause the elliptical block to loosen the threaded seat. Use the tension spring to move the threaded seat away from the threaded rod, thus unlocking the lock. Similarly, operate in the opposite direction to use the elliptical block to press the threaded seat against the outer end of the threaded rod, which makes it easy to switch between adjusting the lock's tight or loose state.

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] Please see Figure 1 A thoracic organ retractor includes an adjusting latch 1, a fine-tuning frame 2, and a hook 3. The adjusting latch 1 is fixedly installed inside the hook 3, and the adjusting latch 1 is threadedly matched with the fine-tuning frame 2. The hook 3 is slidably installed on the outer end of the fine-tuning frame 2. The adjusting latch 1 is released, causing it to loosen from the fine-tuning frame 2. Then, the hook 3 is roughly adjusted. The adjusting latch 1 is then locked, causing it to threadedly connect with the fine-tuning frame 2. Finally, the fine-tuning is performed using the fine-tuning frame 2.
[0030] Please see Figure 2The fine-tuning frame 2 includes a threaded rod 22, a fixed base 23, a knob 24, a fixed hook 25, and a guide rod 26. The threaded rod 22 is rotatably connected to the inner end of the fixed base 23 and passes through the fixed base 23. The knob 24 is fixedly connected to the outer end of the threaded rod 22 and is in movable contact with the fixed base 23. The fixed hook 25 is fixedly connected to the fixed base 23, and the guide rod 26 is fixedly connected to the fixed base 23. Turning the knob 24 causes the threaded rod 22 to rotate, which in turn causes the adjusting latch 1 to move, so that the adjusting latch 1 causes the hook 3 to slide along the threaded rod 22 and the guide rod 26.
[0031] Please see Figure 2 The fine-tuning frame 2 also includes a limiting seat 21, which is fixedly connected to the end of the guide rod 26 facing away from the fixed seat 23. The threaded rod 22 is rotatably mounted on the inner end of the limiting seat 21. The limiting seat 21 is used to limit the sliding limit of the hook 3 along the threaded rod 22 and the guide rod 26.
[0032] Please see Figure 2 and 3 The hook 3 includes a hook body 31, a slide 32, and a buckle 33. The slide 32 is slidably sleeved on the outside of the threaded rod 22 and the guide rod 26. The hook body 31 is fixedly connected to the side end of the slide 32, and the buckle 33 is fixedly connected to the upper end of the slide 32. The threaded rod 22 and the guide rod 26 guide the slide 32 to slide.
[0033] Please see Figure 3 The hook 3 also includes a magnet 34, which is fixedly connected to the inner end of the buckle 33. The magnet 34 is used to attract and tighten the adjusting latch 1 to maintain the locking state of the adjusting latch 1.
[0034] Please see Figure 2 , 34. The adjusting latch 1 includes a rotating shaft 11, a handle 12, a guide seat 14, a slide rod 15, a tension spring 16, a threaded seat 17, an elliptical block 18, and an iron block 19. The iron block 19 is engaged with the latch block 33 and magnetically attracted to the magnet block 34. The guide seat 14 is fixedly connected to the inner end of the slide block 32. The threaded seat 17 is threadedly matched with the threaded rod 22. Both the threaded seat 17 and the elliptical block 18 are located inside the slide block 32, and both the threaded seat 17 and the elliptical block 18 are engaged with the slide block 32. 2. The rotating shaft 11 rotates through the slide block 32, the handle 12 slides through the rotating shaft 11, the slide rod 15 slides through the guide seat 14, and the tension spring 16 is movably sleeved outside the slide rod 15. The slide rod 15 is fixedly connected to the outer end of the threaded seat 17. One end of the tension spring 16 is fixedly connected to the guide seat 14, and the other end is fixedly connected to the threaded seat 17. The elliptical block 18 is fixedly connected to the lower part of the rotating shaft 11 and makes movable contact with the threaded seat 17. Pulling the handle 12 in the opposite direction to the iron block 19 causes the iron block 19 to release the magnet block 34 from the buckle block 33. Then, rotating the handle 12 drives the rotating shaft 11, causing the rotating shaft 11 to drive the elliptical block 18 to release the threaded seat 17. The elastic force of the tension spring 16 causes the threaded seat 17 to move away from the threaded rod 22, thus unlocking the lock. Similarly, operating in the reverse direction uses the elliptical block 18 to press the threaded seat 17 against the outer end of the threaded rod 22, thus switching the locking or unlocking state of the latch 1.
[0035] Please see Figure 4 The adjusting latch 1 also includes a spherical block 13, which is fixedly connected to the end of the handle 12 facing away from the iron block 19. The spherical block 13 increases the contact area between the outer end of the handle 12 and the hand, thus preventing hand injuries.
[0036] Working principle: Turning the knob 24 drives the threaded rod 22 to rotate, which in turn drives the adjusting latch 1 to move. This causes the adjusting latch 1 to slide the hook 3 along the threaded rod 22 and the guide rod 26. Pulling the handle 12 in the opposite direction to the iron block 19 causes the iron block 19 to release the magnet block 34 from the latch block 33. Then, rotating the handle 12 drives the rotating shaft 11, which in turn causes the elliptical block 18 to release the threaded seat 17. The tension spring 16 then uses its elasticity to move the threaded seat 17 away from the threaded rod 22, thus unlocking the device. Similarly, the operation is reversed, using the elliptical block 18 to press the threaded seat 17 against the outer end of the threaded rod 22, thus switching the locking or unlocking state of the adjusting latch 1.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
