Description

Technical Field

[0001] The present invention relates to the technical field of surgical instruments, and in particular to a surgical protection device and a method thereof. Background Art

[0002] Laser and X-ray surgery will not cause obturator nerve reflex, and the safety factor is high, which is especially suitable for intracavitary surgery in urology. Although laser and X-ray surgery have many advantages, they will cause damage to the operator's body, especially the internal organs, during the operation. The existing protection method is that the operator wears lead protective clothing to resist the radiation of laser and X-rays. In order to facilitate the operation, the lead layer of the protective clothing is generally thin, and the protection effect is poor.

[0003] The announcement number CN117959003B discloses a protective device for minimally invasive surgery in urology. By installing a positioning block and a protective curtain assembly in the operating port of the protective device, the operating port can be isolated and protected by the positioning block and the protective curtain assembly to prevent radiation generated by the operation from radiating outward from the operating port, thereby improving the overall protective effect of the protective cover and preventing damage to the body of the medical staff presiding over the operation due to radiation; and a positioning hole is provided on the positioning block. When performing minimally invasive surgery in urology, the positioning block can be slid in the operating port to a position above the stone according to the position of the stone obtained by angiography, and then The puncture needle passes through the positioning hole to puncture the patient's abdomen, and then the surgical instrument with a laser head and a stone removal net is inserted into the patient's body through the positioning hole and the puncture port to perform lithotripsy and stone removal surgery. By setting the positioning block and the positioning hole, the surgical instrument can be assisted in positioning during the operation, thereby improving the stability of the surgical instrument, thereby improving the stability during the surgical operation, which is conducive to the smooth progress of the operation. At the same time, in the process of moving and adjusting the position of the positioning block, the positioning block can drive the protective curtain assembly to stretch and expand or fold and contract, so that the positioning block can cooperate with the protective curtain assembly to always maintain sealed protection for the operating port, thereby preventing radiation emission.

[0004] The existing protective cover has openings on both sides, but the side openings of the existing protective cover do not have a fitting adjustment mechanism. When the protective cover is used to cover and isolate the abdomen of the human body, it cannot fit the curve of the human body well for isolation. When the X-rays penetrate the human body, they will interact with the human body tissue and produce scattering. The scattered X-rays may be emitted from the side openings to form light leakage. The leaked X-rays may also cause additional damage to the human body through the openings. The overall protective effect is not comprehensive enough and has certain limitations in actual use.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a surgical protective device, comprising a protective cover 1, an inspection port 2 opened at the top of the protective cover 1, and openings 3 opened through both sides of the protective cover 1, lead plates 4 are fixedly connected to the inner walls of both sides of the protective cover 1 near the opening 3, a sprocket drive rod 5 is rotatably installed through one side of the top of the protective cover 1 near the opening 3, a chain 6 is connected between the sprocket ends of the two sprocket drive rods 5, a stepper motor 7 is fixedly connected to the outside of one side of the protective cover 1, and the output end of the stepper motor 7 is coaxially fixed with one end of one of the sprocket drive rods 5, and an isolation mechanism is provided on one side of the sprocket drive rod 5 located inside the protective cover 1; the isolation mechanism includes a lead curtain 8, the lead curtain 8 is placed in close contact with the outer surface of the sprocket drive rod 5 located inside the protective cover 1, a guiding mechanism is provided on the side of the lead curtain 8 near the inspection port 2, and a disinfection mechanism is provided on the outside of one side of the protective cover 1.

[0039] Screw rods 10 are longitudinally arranged at the bottom ends of both sides of the lead curtain 8 close to the sprocket drive rod 5, and limiting grooves 11 are embedded inside the side of the protective cover 1 close to the screw rod 10. The screw rod 10 is rotatably installed inside the corresponding limiting groove 11, and a bevel gear set 9 is arranged for transmission connection between the top end of the screw rod 10 and one side of the outside of the sprocket drive rod 5. A limiting block 12 is threadedly connected to the outside of one side of the screw rod 10, and a limiting rod 15 is transversely fixed to the limit block 12 on the side close to the lead curtain 8.

[0040] A fixing block 14 is installed on the outside of one side of the limiting rod 15 through a sliding engagement, a positioning block 13 is fixedly connected to one side of the fixing block 14, and one side of the positioning block 13 is fixedly connected to the edge of one side of the bottom end of the lead curtain 8, an isolating elastic sheet 17 is fixedly connected to the middle position of the bottom end of the lead curtain 8 near the positioning block 13, and a reset component is arranged on one side of the fixing block 14.

[0041] In this embodiment, combined with Figure 1 - Figure 5As shown, when the device is in use, the patient first lies flat on the operating table, and the protective cover 1 is set on the patient's abdomen. Then, the stepper motor 7 is started to rotate forward, and the connection transmission of the sprocket drive rod 5 and the chain 6 is coordinated, so that the sprocket drive rod 5 at the openings 3 on both sides rotate synchronously, and the rotation of the sprocket drive rod 5 is coordinated with the transmission connection installation of the bevel gear set 9, thereby driving the screw rods 10 on both sides to rotate synchronously, thereby driving the limit block 12 with an external through-thread connection to move downward inside the limit groove 11, and the connection installation of the limit block 12 with the positioning block 13, the fixing block 14 and the limit rod 15 The lead curtain 8 is installed so that when the limit block 12 moves downward, it drives the lead curtain 8 fixed by the positioning blocks 13 on both sides of the top to start to descend synchronously, so as to isolate the gap between the opening 3 and the human body. When the lead curtain 8 descends to a certain extent, the insulating elastic sheet 17 at the bottom of the lead curtain 8 contacts the patient's abdomen, and cooperates with the limit rod 15 to slide through the fixing block 14 and the positioning block 13, so that when the lead curtain 8 continues to descend, the positioning blocks 13 on both sides will drive the fixing block 14 to slide outside the limit rod 15, so that the positioning blocks 13 on both sides pull the two sides of the lead curtain 8 to move toward the center of the patient's back waist on both sides. Figure 6 As shown, the side of the lead curtain 8 is well fitted and wrapped with the curve of the human body, so that when the protective cover 1 is used to isolate the abdomen of the human body, its side opening 3 can also be isolated and protected by the lead curtain 8, so that X-rays will not be emitted from the side opening 3 to form light leakage, thereby avoiding additional harm to the human body, and the overall protection effect is comprehensive.

[0042] Example 2: Please refer to Figure 7 - Figure 8 This embodiment further explains the first embodiment. The reset assembly includes a compression spring 16. The compression spring 16 is installed on the outside of one side of the limit rod 15 through the sleeve. The two ends of the compression spring 16 are respectively installed on one side of the fixed block 14 and the limit rod 15.

[0043] The guiding mechanism includes a positioning plate 18, which is fixedly connected to the outer surface of the lead curtain 8 on one side close to the inspection port 2. A slide groove 19 is horizontally embedded on the inner wall of the protective cover 1 on one side close to both ends of the positioning plate 18. A slide rod 20 is fixedly installed inside the slide groove 19. One end of the positioning plate 18 passes through the outside of the slide rod 20 on the corresponding side for sliding installation. A reset spring 21 is sleeved through the outside of one side of the slide rod 20. The two ends of the reset spring 21 are respectively installed on one side of the positioning plate 18 and the inner wall of the slide groove 19.

[0044] In this embodiment, when the detection is completed, the stepper motor 7 is controlled to start reversing, thereby driving the lead curtain 8 to be recovered. During the recovery process, the reset spring 21 on one side of the lead curtain 8 that was originally stretched and expanded when descending begins to rebound synchronously, and at the same time cooperates with the through sliding connection of the slide rod 20 and the positioning plate 18, so that the lead curtain 8 can be recovered smoothly as a whole, and at the same time, it is ensured that the surface of the lead curtain 8 after recovery is always in a tightened and flat state, so as to avoid the lead curtain 8 being folded or stacked for a long time without use, causing the lead rubber and other materials inside the lead curtain 8 to fatigue, deform, or even break, affecting the protective performance and service life, thereby extending the service life of the lead curtain 8 and ensuring the protective effect.

[0045] It should also be noted that when the reset spring 21 rebounds and pulls the lead curtain 8 to reset and be stored, when the lead curtain 8 is recovered to a certain height, the compression spring 16 on one side of the limit rod 15 begins to resist the fixed block 14 and the positioning block 13 on one side to move back and reset, so that the two sides of the bottom end of the lead curtain 8 can also move back and reset and spread out flat, ensuring the storage effect.

[0046] Example 3: Please refer to Fig. 9 - Fig.12 This embodiment further explains Example 2. The disinfection mechanism includes a liquid storage tank 22, which is fixedly connected to the outside of one side of the protective cover 1. A suction component is provided on the inner wall of the side of the protective cover 1 close to the opening 3; the suction component includes a suction cylinder 23, which is longitudinally installed on the inner wall of one side of the protective cover 1, and a suction pipe 28 is provided at the top of the suction cylinder 23, and one end of the suction pipe 28 is installed inside the liquid storage tank 22. A one-way valve 29 is provided inside one side of the suction pipe 28, and a piston block 24 is installed in the internal sliding seal of the suction cylinder 23. A pull rope 25 is fixedly connected to the bottom end of the piston block 24, and a traction component is provided on one side of the pull rope 25.

[0047] The traction assembly includes a roller 26 and a connecting block 27. The roller 26 is rotatably mounted on the inner wall of the protective cover 1, and there are a plurality of rollers 26. The connecting block 27 is fixedly connected to the outside of one side of the limit block 12. One end of the pull rope 25 is wound around and passes through a plurality of rollers 26 and is fixedly connected to one side of the connecting block 27.

[0048] An extrusion assembly is provided at the top of the piston block 24; the extrusion assembly includes a tension spring 30 and a conducting joint 33, the two ends of the tension spring 30 are respectively installed on one side of the inner wall of the piston block 24 and the top of the suction cylinder 23, the conducting joint 33 is installed through the outside of the side of the protective cover 1 close to the lead curtain 8, the conducting joint 33 is C-shaped, and a connecting pipe 31 is installed on one side of the conducting joint 33, and the input end of the connecting pipe 31 is connected to the top of the suction cylinder 23, a one-way valve 2 32 is installed inside one side of the connecting pipe 31, and a spray assembly is provided on one side of the conducting joint 33.

[0049] The spray assembly includes a discharge pipe 34, two of which are symmetrically arranged, and the two discharge pipes 34 are respectively placed on the top and bottom sides of the lead curtain 8, and one end of the two discharge pipes 34 is conductively connected to one end of the conductive joint 33, and a plurality of nozzles 35 are evenly spaced and penetrated on one side of the discharge pipe 34 close to the lead curtain 8.

[0050] In this embodiment, when the stepper motor 7 starts to rotate forward and the screw rod 10 rotates to drive the limit block 12 to move downward, it will drive the connecting block 27 and the pull rope 25 on one side to move synchronously, and cooperate with the limiting rolling guidance of the roller 26 to drive the piston block 24 inside the suction cylinder 23 to descend. At this time, the suction tube 28 and the one-way valve 29 are connected and installed, so that the disinfectant stored in the liquid storage tank 22 in advance is sucked into the interior of the suction cylinder 23, completing the synchronous and automatic suction of the disinfectant.

[0051] It should also be noted that when the stepper motor 7 starts to reverse, the screw rod 10 rotates to drive the limit block 12 to move upward, thereby driving the lead curtain 8 to be retracted. When the limit block 12 rises, the pull rope 25 is loosened, and the rebound of the tension spring 30 inside the suction cylinder 23 is cooperated, thereby driving the piston block 24 to move upward synchronously. Through the rising and squeezing movement of the piston block 24, the disinfectant originally drawn into the suction cylinder 23 is squeezed into the interior of the connecting pipe 31, and finally, through the conduction of the conducting joint 33 and the discharge pipe 34, the disinfectant is sprayed out from the spray outlets of multiple nozzles 35, so that the disinfectant is evenly sprayed on the front and back sides of the lead curtain 8, thereby evenly spraying and disinfecting the inner and outer surfaces of the lead curtain 8. Spraying disinfectant can effectively kill pathogens on the lead curtain 8, prevent them from spreading between different people, reduce the risk of cross infection, and ensure the overall use effect.

[0052] The present invention also provides a method for using a surgical protection device, comprising the following steps:

[0053] S1: First, the patient lies flat on the operating table, and the protective cover 1 is set on the patient's abdomen;

[0054] S2: Then the stepper motor 7 starts forward rotation, and cooperates with the connection transmission of the sprocket drive rod 5 and the chain 6, so that the isolation mechanisms at the openings 3 on both sides are started and operated synchronously, so that the openings 3 on both sides of the protective cover 1 are isolated and covered by the lead curtain 8;

[0055] S3: After the detection is completed, the stepper motor 7 is controlled to start reverse rotation, thereby driving the isolation mechanism to run in the reverse direction and cooperating with the reset assembly to install, so as to recycle the lead curtain 8 at the side opening 3. During the recycling process, the guide mechanism is operated in cooperation, so that the recycled lead curtain 8 is unfolded and flattened for storage;

[0056] S4: When the lead curtain 8 is recovered, the disinfection mechanism will be triggered to run, so as to spray the surface of the recovered lead curtain 8 with disinfectant for disinfection.
