Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a portable moisturizing device for robotic surgical forceps. Background Art

[0002] With the rapid development of medical technology, robot-assisted surgery has become rapidly popular around the world. The precision and high value of surgical instruments have placed higher demands on postoperative pretreatment. Robotic surgical instruments are expensive, have delicate structures, and are made of special materials. The lumens are slender and cannot be disassembled, and there are blind spots in processing. The requirements for instrument reprocessing are high, which brings great challenges to disinfection and supply centers.

[0003] Research shows that the current cleaning pass rate of robotic forceps is not high. Organic matter such as blood and tissue fluid is easily retained in the joints and gaps of the robotic forceps, making cleaning difficult. If not handled in time, it can easily lead to protein denaturation and oxidative corrosion, reducing the life of the instrument and surgical accuracy. Secondly, the incidence of prolonged retention and transport time of robotic forceps after use was 6.0% and 66.7% respectively. Failure to pre-treat instruments promptly or inadequately is the main cause of frequent re-cleaning. Residual organic pollutants make cleaning more difficult, corrode the protective coating of the instruments, cause rust on the instruments, and increase medical costs. To solve this problem, the current method used in the existing technology is to moisturize the forceps by using an immersion box in the disinfection supply center to immerse the forceps in it to achieve the moisturizing effect. However, the traditional immersion box in the decontamination room of the disinfection supply center is open, and the liquid is easy to spill, causing environmental pollution. It does not meet the requirements of hospital infection management, and there are often situations in which liquids are manually prepared and multiple instruments are immersed together, which can easily cause pollutants on the surfaces of different instruments to contact and spread with each other. Summary of the Invention

[0004] The object of the present invention is to provide a portable moisturizing device for robotic surgical forceps to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides a portable moisturizing device for robotic surgical forceps, including a moisturizing device main body, the moisturizing device main body also includes a cavity cover, the cavity cover is embedded with an anti-backflow dynamic film, the anti-backflow dynamic film is hollow, the bottom of the anti-backflow dynamic film extends to the interior of the cavity cover and is provided with a cross blade, and the cross blade is elastic.

[0006] Furthermore, a sealing film layer is fixedly installed at the bottom end of the anti-backflow dynamic film, the sealing film layer is bent and protruded downward, the sealing film layer is elastic, and the cross blade is opened through the bottom end of the sealing film layer.

[0007] Furthermore, an elastic pressing sheet is fixedly mounted on the inner wall of the anti-backflow dynamic film. One end of the elastic pressing sheet away from the anti-backflow dynamic film extends toward the cross edge. The outer wall of the elastic pressing sheet is in close contact with the inner wall of the sealing film layer.

[0008] Furthermore, the bottom end of the anti-backflow dynamic film is gradually narrowed from the top end, so that the bottom end circle diameter of the anti-backflow dynamic film is smaller than the top end circle diameter, the top end circle diameter of the sealing film layer is the same as the bottom end circle diameter of the anti-backflow dynamic film, and the bottom end of the sealing film layer is bent and protruded downward.

[0009] Furthermore, a sealing cap is provided on the top of the cavity cover, and a partial area of ​​the anti-backflow dynamic film extends to the top of the cavity cover, so as to clamp the anti-backflow dynamic film after the sealing cap is covered on the top of the cavity cover.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0018] The present invention provides a technical solution: See Figure 1-Figure 7 As shown, a portable moisturizing device for robotic surgical forceps includes a moisturizing device body 1, and the moisturizing device body 1 also includes a cavity sleeve 101. The cavity sleeve 101 is embedded with an anti-backflow dynamic film 3, and the anti-backflow dynamic film 3 is hollow. The bottom of the anti-backflow dynamic film 3 extends to the interior of the cavity sleeve 101 and is provided with a cross blade 6, and the cross blade 6 is elastic.

[0019] Before moisturizing the robotic arm pliers, first look at Figure 1 , Figure 1 First, use a syringe to inject the pretreatment agent into the container of the moisturizing device body 1, that is, the cavity sleeve 101. The pretreatment agent is a multi-enzyme cleaning solution with a 1:200 configuration. The syringe is 20ml. Then insert the pliers into the cavity sleeve 101 and then look at Figure 5 , the pliers are inserted downward from the top of the cavity sleeve 101, and the pliers first enter the anti-backflow dynamic film 3, and then the cross blade 6 will be squeezed, and the four blade edges will be stretched to the four sides, so that the opening size of the cross blade 6 becomes larger, and then the pliers can pass through the cross blade 6 and extend into the cavity sleeve 101; After the pliers enter the cavity sleeve 101, they can be soaked in the pretreatment agent in the cavity sleeve 101. When the soaking is completed and the pliers are pulled out, the pliers body exerts an upward thrust on the bottom of the anti-backflow dynamic film 3, causing the bottom end of the anti-backflow dynamic film 3 to deform upward. After the pliers are pulled out, the cross blade 6 will close, so that the entrance to the cavity sleeve 101 is blocked, completing the seal and preventing the pretreatment agent in the cavity sleeve 101 from flowing back out. The cavity cover 101 is made of transparent hard plastic, which makes it easy to see whether there is too much or too little pretreatment agent in the cavity cover 101. The cavity cover 101 is made of high-strength PP material with a thickness of 1.2mm, providing a solid physical barrier, completely wrapping the clamp end in the cavity cover 101 to avoid direct contact with other instruments or hard objects, providing a stable protective environment during cleaning and transportation, and avoiding damage to the front end of the instrument.

[0020] See Figure 2-Figure 6 A sealing film layer 5 is fixedly installed at the bottom end of the anti-backflow dynamic film 3. The sealing film layer 5 is bent and protruded downward. The sealing film layer 5 is elastic. A cross blade 6 is opened through the bottom end of the sealing film layer 5.

[0021] The sealing film layer 5 is made of the same material as the rubber gloves. When the pliers are inserted into the cross-shaped blade 6, the sealing film layer 5 can be deformed so that the pliers can smoothly open the cross-shaped blade 6. Then, when the pliers are pulled upward, the sealing film layer 5 will be deformed upward. After the pliers are removed, the rubber walls around the cross-shaped blade 6 will be squeezed against each other due to elastic contraction, forming a seal.

[0022] See Figure 6 An elastic pressing piece 7 is fixedly installed on the inner wall of the anti-backflow dynamic film 3, and one end of the elastic pressing piece 7 away from the anti-backflow dynamic film 3 extends toward the cross edge 6, and the outer wall of the elastic pressing piece 7 is in close contact with the inner wall of the sealing film layer 5.

[0023] The elastic pressing piece 7 supports the sealing film layer 5 to prevent the sealing film layer 5 from deforming too much upward when the pliers are pulled upward. When the sealing film layer 5 falls and bends in the figure, the cross edge 6 is in an open state, which is convenient for inserting the pliers. The bending of the bottom end of the sealing film layer 5 gradually deforms upward to close the cross edge 6. However, if the sealing film layer 5 deforms too high upward, part of the cross edge 6 will be opened. Therefore, the elastic pressing piece 7 limits the height of the upward deformation of the sealing film layer 5 to ensure that the cross edge 6 can be closed after the pliers are removed.

[0024] See Figure 6 The bottom end of the anti-backflow dynamic film 3 is gradually narrowed from the top end, so that the bottom end diameter of the anti-backflow dynamic film 3 is smaller than the top end diameter. The top end diameter of the sealing film layer 5 is the same as the bottom end diameter of the anti-backflow dynamic film 3, and the bottom end of the sealing film layer 5 is bent and protruded downward.

[0025] The anti-backflow dynamic film 3 is narrow at the bottom and wide at the top. In this way, after the pliers are inserted into the cross blade 6, the sealing film layer 5 will be deformed. Therefore, after the cross blade 6 is stretched open, the sealing film layer 5 will expand toward the periphery, so that there is a sufficient distance between the sealing film layer 5 and the inner wall of the cavity sleeve 101. The top ring diameter of the anti-backflow dynamic film 3 is adapted to the cavity sleeve 101, which is convenient for support in the cavity sleeve 101 to prevent the anti-backflow dynamic film 3 from being displaced significantly, and at the same time facilitate the initial insertion of the pliers.

[0026] See Figure 3-Figure 6 The top of the cavity sleeve 101 is provided with a sealing cap 2, and part of the anti-backflow dynamic film 3 extends to the top of the cavity sleeve 101, so as to clamp the anti-backflow dynamic film 3 after the sealing cap 2 is sleeved on the top of the cavity sleeve 101.

[0027] The sealing cap 2 is put on the top of the cavity sleeve 101, and part of the area of ​​the anti-backflow dynamic film 3 extends on the top of the cavity sleeve 101. In this way, after the sealing cap 2 is put on the cavity sleeve 101, the anti-backflow dynamic film 3 can be stuck in the cavity sleeve 101 to prevent the anti-backflow dynamic film 3 from being taken out of the cavity sleeve 101 when the pliers are pulled out.

[0028] See Figure 6 An extension plate 4 is fixedly installed on the outer wall of the anti-backflow dynamic membrane 3, and the bottom of the extension plate 4 conflicts with the top of the cavity sleeve 101. A pressure ring 8 is fixedly installed on the inner wall of the sealing cap 2. After the sealing cap 2 is sleeved on the top of the cavity sleeve 101, the bottom of the pressure ring 8 conflicts with the top of the extension plate 4.

[0029] After the anti-backflow dynamic film 3 is inserted into the cavity sleeve 101, the bottom of the extension plate 4 contacts the top of the cavity sleeve 101, and then the sealing cap 2 is put on the cavity sleeve 101 until the bottom of the pressure ring 8 contacts the top of the extension plate 4, and then the inner wall of the sealing cap 2 contacts the outer wall of the cavity sleeve 101 tightly, so that the sealing cap 2 is fixed on the top of the cavity sleeve 101, so that when the pliers are pulled out, the anti-backflow dynamic film 3 will not be easily brought out, so that the anti-backflow dynamic film 3 is stable in the cavity sleeve 101.

[0030] See Figure 6-Figure 7 The outer wall of the cavity sleeve 101 is further provided with an inclined surface 102 , the top of the inclined surface 102 is inclined toward the central axis of the cavity sleeve 101 , and the sealing cap 2 is sleeved on the inclined surface 102 .

[0031] The inner diameter of the sealing cap 2 matches the top diameter of the inclined surface 102 , so that when the sealing cap 2 moves gradually downward along the inclined surface 102 , the connection between the sealing cap 2 and the inclined surface 102 will become tighter and tighter, preventing the sealing cap 2 from easily falling off the cavity sleeve 101 .

[0032] See Figure 7An elastic pad 9 is fixedly installed on the outer wall of the inclined surface 102 , and the inner wall of the sealing cap 2 is in close contact with the outer wall of the elastic pad 9 .

[0033] The first function of the elastic pad 9 is to increase the friction between the outer wall of the inclined surface 102 and the inner wall of the sealing cap 2, so as to prevent the sealing cap 2 from being pulled out together with the force of the pliers when pulling out. At the same time, the elastic pad 9 is supported between the inclined surface 102 and the sealing cap 2, so that the two are clamped more tightly. Working principle: Before moisturizing the robotic arm pliers, first look at Figure 1 , Figure 1 First, use a syringe to inject the pretreatment agent into the container of the moisturizing device body 1, that is, the cavity sleeve 101. The pretreatment agent is a multi-enzyme cleaning solution with a 1:200 configuration. The syringe is 20ml. Then insert the pliers into the cavity sleeve 101 and then look at Figure 5 , the pliers are inserted downward from the top of the cavity sleeve 101, and the pliers first enter the anti-backflow dynamic film 3, and then the cross blade 6 will be squeezed, and the four blade edges will be stretched to the four sides, so that the opening size of the cross blade 6 becomes larger, and then the pliers can pass through the cross blade 6 and extend into the cavity sleeve 101; After the pliers enter the cavity sleeve 101, they can be soaked in the pretreatment agent in the cavity sleeve 101. When the soaking is completed and the pliers are pulled out, the pliers body exerts an upward thrust on the bottom of the anti-backflow dynamic film 3, causing the bottom end of the anti-backflow dynamic film 3 to deform upward. After the pliers are pulled out, the cross blade 6 will close, so that the entrance to the cavity sleeve 101 is blocked, completing the seal and preventing the pretreatment agent in the cavity sleeve 101 from flowing back out. The cavity cover 101 is made of transparent hard plastic, making it easy to see whether the pretreatment agent in the cavity cover 101 is too much or too little. The cavity cover 101 is made of high-strength PP material with a thickness of 1.2mm, providing a solid physical barrier, completely wrapping the clamp tip in the cavity cover 101 to avoid direct contact with other instruments or hard objects, providing a stable protective environment during cleaning and transportation, and preventing damage to the front end of the instrument; The sealing film layer 5 is made of the same material as the rubber gloves. When the pliers are inserted into the cross-shaped blade 6, the sealing film layer 5 can be deformed so that the pliers can smoothly open the cross-shaped blade 6. Then, when the pliers are pulled upward, the sealing film layer 5 will be deformed upward. After the pliers are removed, the rubber walls around the cross-shaped blade 6 will be squeezed against each other due to elastic contraction, forming a seal.

[0034] The elastic pressing piece 7 supports the sealing film layer 5 to prevent the sealing film layer 5 from deforming too much upward when the pliers are pulled upward. When the sealing film layer 5 falls and bends in the figure, the cross edge 6 is in an open state, which is convenient for inserting the pliers. The bending of the bottom end of the sealing film layer 5 gradually deforms upward to close the cross edge 6. However, if the sealing film layer 5 deforms too high upward, part of the cross edge 6 will be opened. Therefore, the elastic pressing piece 7 limits the height of the upward deformation of the sealing film layer 5 to ensure that the cross edge 6 can be closed after the pliers are removed.
