Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a loose body remover used in orthopedic arthroscopic surgery. Background Art

[0002] During arthroscopic surgery in orthopedics, it is sometimes necessary to clean loose bodies from the joint cavity. Generally, the loose bodies are removed under arthroscopy using ordinary removers such as surgical forceps. Since arthroscopic surgery must fill the joint with sufficient water, and loose bodies are highly mobile in water, when ordinary surgical forceps are used to grasp the loose bodies, the loose bodies can easily slip and move out of the field of view of the arthroscope.

[0003] Existing loose body extractors are generally simple forceps structures, which have average stability during operation and cannot fix the loose bodies well. Based on this, we propose an improved loose body extractor for orthopedic arthroscopic surgery. Summary of the invention

[0004] The main purpose of the utility model is to provide a loose body remover for orthopedic arthroscopic surgery, which can effectively solve the technical problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, a loose body remover for orthopedic arthroscopic surgery includes a clamp frame 1, a push-pull rod 4, a push-pull block 5, two splints 6, a push frame 9, a slide 11, two finger rings 12, two connecting handles 13, a screw rod 16 and a slider 18. One end of the two splints 6 are rotatably connected to the push-pull block 5, and the push-pull block 5 and the push frame 9 are fixedly connected with the push-pull rod 4. The two connecting handles 13 are respectively connected between the upper and lower outer walls of the push frame 9 and the two finger rings 12. The slider 18 is threadedly sleeved on the outer wall of the screw rod 16. The two finger rings 12 are respectively fixedly connected to the upper and lower outer walls of the slide 11. The slide 11 is slidably sleeved on the outer end of the screw rod 16. The clamp frame 1 is respectively provided with a slide groove 1 8 and a slide groove 2 10. The push frame 9 is slidably sleeved in the slide groove 1 8, and the slide 11 and the slider 18 are slidably sleeved in the slide groove 2 10.

[0023] In this embodiment, a spring 17 is fixedly connected between the slide 11 and the inner wall of the second slide groove 10. The spring 17 is movably sleeved on the outer end of the screw rod 16. The spring 17 buffers the pressure of the slide 11, thereby buffering the clamping force of the two splints 6 to avoid excessive clamping force and causing the loose body to break.

[0024] In this embodiment, a convergence groove 2 is opened at one end of the clamp frame 1, and the push-pull block 5 is slidably set in the convergence groove 2. One end of the push-pull rod 4 passes through the convergence groove 2, and the other end passes through a slide groove 8. The push-pull rod 4 is driven to move by the push frame 9, thereby driving the push-pull block 5 to slide in the convergence groove 2.

[0025] In this embodiment, a fixing column 3 is fixedly connected between the front and rear inner walls of the convergence groove 2, and the fixing column 3 is arranged between two clamping plates 6. When the push-pull block 5 drives the two clamping plates 6 to move toward the notch of the convergence groove 2, the two clamping plates 6 can be unfolded under the action of the fixing column 3.

[0026] In this embodiment, the two clamping plates 6 are fixedly connected to the outer walls of the opposite side of one end away from the push-pull block 5 with clamping pads 7, and the surface of the clamping pads 7 is made of a corrugated structure to increase friction and improve the clamping stability of the loose body.

[0027] In this embodiment, gear 19 and gear 20 are rotatably connected in the clamp frame 1, one end of the screw rod 16 passes through the clamp frame 1 and is fixedly sleeved on the inner end of gear 19, and the upper end of gear 20 protrudes from the upper end surface of the clamp frame 1, so that it is convenient to slowly rotate gear 20 with the thumb to drive gear 19 to rotate, thereby driving the screw rod 16 to rotate, thereby realizing the control of the movement of the slider 18.

[0028] In this embodiment, one end of the clamp frame 1 is fixedly connected to a mounting post 14 , and the other end of the mounting post 14 is fixedly connected to a palm rest 15 , so as to provide support when the finger ring 12 is pulled by fingers.

[0029] It should be noted that the utility model is a loose body extractor for orthopedic arthroscopic surgery. When in use, the palm rest 15 is placed against the palm of the hand, two fingers are passed through the finger ring 12, and then the forceps frame 1 is extended into the wound, the clamp pads 7 are moved to both sides of the loose body, and then the finger ring 12 is pulled by hand, and the push frame 9 is driven to move through the connecting handle 13, and then the push-pull block 5 is driven to move through the push-pull rod 4. Under the limiting action of the notch of the convergence groove 2, the two splints 6 are relatively moved, and then the loose body is clamped and fixed by the clamp pad 7, and then the thumb slowly rotates the gear 2 20, and the meshing gear 1 19 is driven by the gear 19 to drive the screw rod 16 to rotate, and then the slider 18 is driven to move, so that it is pressed on one side of the slide 11, and the slide 11 is limited by the slider 18. At this time, the slide 11 can be prevented from being reset, resulting in loose clamping force, causing the problem of loose body slipping, thereby improving the stability of the operation;

[0030] During the movement of the above-mentioned slide 11, the spring 17 buffers the pressure, which can effectively prevent the slide 11 from moving with too much force, resulting in excessive clamping force between the two clamping plates 6, causing the loose body to be cracked or crushed.

[0031] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
