[0028] Embodiment 1

[0029] Reference Figure 1 and Figure 2, the protective film for the da Vinci robot arm, the protective film 1 is a three-section cylindrical structure with a closed inner end and an open outer end, the three-section cylindrical structure is formed with two intersegments 101, the two intersegments 101 and the closed end are arranged in an annular convexity, that is, the expansion is processed, and the thickness is greater than the thickness of the intersegmental part 101 of the protective film 1. Since the joints of the da Vinci robot arm have a large range of motion, the expansion can reduce the probability of damage to the protective film 1 and improve its use strength. The protective film 1 is a medical sterile film, and the material can refer to the existing plastic protective film.

[0030] For the above example, those skilled in the art should know that when implementing the above technical solution, the protective film 1 is not limited to providing three-section cylindrical structures and corresponding two intersegmental parts 101, and the number of cylindrical structures and intersegmental parts 101 is determined by the number of joints of the Da Vinci robotic arm.

[0031] The open end of the protective film 1 is provided with a constriction piece, which includes a folded edge 102 folded outward along the open end of the protective film 1 and a medical nylon rope 103 for tightening the folded edge 102. The medical nylon rope 103 is arranged in the folded edge 102, and the medical nylon rope 103 is led out from the folded edge 102. By tightening the medical nylon rope 103, the folded edge 102 can be tightened, which can achieve the effect of preventing dust and pollution at the end.

[0032] The da Vinci robotic arm includes an instrument sterile adapter, a cannula sterile adapter, and an arm clamp. The instrument sterile adapter, the cannula sterile adapter, and the arm clamp can be detachably set. An instrument adapter hole 104, a sleeve adapter hole 105 and an arm clamp hole 106 are respectively provided at positions corresponding to the sterile instrument adapter, the sleeve sterile adapter and the arm clamp on the protective film 1, and the edges of the instrument adapter hole 104, the sleeve adapter hole 105 and the arm clamp hole 106 are provided with a protective ring 2 made of medical plastic material, the protective ring 2 is folded toward the outer surface of the protective film 1 and formed with a gasket 201, the instrument adapter hole 104, the sleeve adapter hole 105 and the arm clamp hole 106 correspond to patches 3 respectively, the patch 3 is a frame-shaped structure, and a connecting mechanism is provided between the patch 3 and the gasket 201, the connecting mechanism includes a card groove 202 arranged circumferentially along the surface of the gasket 201, and a card protrusion 301 arranged on one side of the patch 3, and the card protrusion 301 can be snap-connected with the corresponding card groove 202. The other side of the patch 3 is provided with an adhesive layer 302 , on which a release film 303 that can be torn off is provided. The adhesive layer 302 is used to bond and fix the above-mentioned sterile adapter for instruments, sterile adapter for cannulas and arm clamps.

[0033] For the above example, those skilled in the art should be aware that when implementing the above technical solution, the size of the protective film 1 is determined by the size specifications of the da Vinci robotic arm, and the sizes of the corresponding instrument adapter hole 104, cannula adapter hole 105 and arm clamp hole 106 are also determined by the size specifications of the instrument sterile adapter, cannula sterile adapter and arm clamp, respectively.

[0034] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, the sterile instrument adapter, the sterile cannula adapter and the arm clamp are all used as adapters to match the da Vinci robotic arm, and the da Vinci robotic arm is limited to matching the connection of the above three types of adapters, and can also match the connection of other equipment. The number of holes on the corresponding protective film 1 and the corresponding guard ring 2 are also set to be more.

[0035] The interface ends of the instrument sterile adapter, the sleeve sterile adapter and the arm clamp are matched with corresponding patches 3, and the patch 3 is adapted to the contour of the corresponding interface end face. The interface ends of the instrument sterile adapter, the sleeve sterile adapter and the arm clamp can pass through the middle of the three patches 3 and connect to the da Vinci robot arm. The three patches 3 can be bonded to the edges of the interface end faces of the instrument sterile adapter, the sleeve sterile adapter and the arm clamp through the corresponding adhesive layer 302. It should be noted that before this operation, the instrument sterile adapter, the sleeve sterile adapter and the arm clamp need to be removed from the original protective film 1 and disinfected before they can be used again.

[0036] The cross-sectional areas of the interface end faces of the sterile instrument adapter, the sterile sleeve adapter and the arm clamp are respectively smaller than the cross-sectional areas of the corresponding patches 3, that is, the projection areas of these interface end faces on the corresponding patches 3 are all smaller than the areas of the corresponding patches.

[0037] Here’s how it works:

[0038] When in use, the sterile adapter for instruments, the sterile adapter for sleeves and the arm clamp on the da Vinci mechanical arm can be removed from the original protective film 1 and disinfected before secondary use. After that, the original protective film 1 on the da Vinci mechanical arm can be taken off and a new unused protective film 1 can be put on. Subsequently, the sterile adapter for instruments, the sterile adapter for sleeves and the interface ends of the arm clamp can be respectively passed through the middle of the three patches 3, and the three patches 3 can be respectively bonded to the edges of the interface end faces of the sterile adapter for instruments, the sterile adapter for sleeves and the arm clamp through the corresponding adhesive layers 302. After that, when connected to the da Vinci mechanical arm, the corresponding card groove 202 of the gasket 201 is snap-connected with the card protrusion 301 of the patch 3, so as to achieve the connection effect, and achieve the effect of only replacing the protective film 1 and retaining the adapter, so as to achieve the purpose of significantly reducing the cost of using the film. When the protective film 1 is used, it can play a good dustproof and anti-pollution effect.

[0039] At the same time, the sterile instrument adapter, the sterile sleeve adapter and the arm clamp can also be cut off along the peripheral area of ​​the protective film 1 to be replaced, and the inner surface of the cut protective film 1 with these adapters can be bonded to the adhesive layer 302 of the subsequent new patch 3. After bonding, the protrusion 301 of the patch 3 can be engaged and fixed on the gasket 201.

[0040] Embodiment 2

[0041] Reference Figure 3 The difference between this embodiment and the first embodiment is that:

[0042] The connection mechanism also includes an annular airbag 4 matched and arranged along the periphery of the gasket 201, and a one-way inflation nozzle 401 is installed on the annular airbag 4. The needle of the existing needle syringe can be inserted into the one-way inflation nozzle 401 to inflate the annular airbag 4, and the annular airbag 4 can be inflated and expand to block the gap between the gasket 201 and the patch 3.

[0043] Here’s how it works:

[0044] After the card slot 202 of the gasket 201 is snap-connected with the card protrusion 301 of the patch 3, the needle of the existing syringe can be inserted into the one-way inflation nozzle 401, and the annular airbag 4 can be inflated to expand the annular airbag 4 and effectively block the gap between the gasket 201 and the patch 3 to ensure the sealing effect, further ensuring the good dust and pollution prevention effect at the connection between the protective film 1 and the adapter.

[0045] Embodiment 3

[0046] Reference Figure 4 The difference between this embodiment and the first embodiment is that:

[0047] The connection mechanism also includes a first magic tape layer 5 matched along the surface of the gasket 201 and a second magic tape layer 6 matched on one side of the patch 3. The first magic tape layer 5 and the second magic tape layer 6 are connected by magnetic attraction.

[0048] Here’s how it works:

[0049] The connection between the gasket 201 and the patch 3 can be achieved by bonding the corresponding first magic tape layer 5 and the second magic tape layer 6 to achieve a convenient and fast connection effect. The first magic tape layer 5 and the second magic tape layer 6 make the bonding range larger and are flexible and can fit the surface of the Da Vinci robotic arm. The overall connection effect is more flexible, the operation is more convenient and faster, and can ensure good dust and pollution prevention effects at the connection between the protective film 1 and the adapter.

[0050] Embodiment 4

[0051] Reference Figure 5The difference between this embodiment and the first embodiment is that:

[0052] The connection mechanism also includes a first magnetic attraction layer 7 matched along the surface of the gasket 201, and a second magnetic attraction layer 8 matched on one side of the patch 3, and the first magnetic attraction layer 7 and the second magnetic attraction layer 8 are bonded and matched. The first magnetic attraction layer 7 and the second magnetic attraction layer 8 are both flexible layers.

[0053] Here’s how it works:

[0054] The connection between the gasket 201 and the patch 3 can achieve a connection effect through the magnetic matching of the first magnetic layer 7 and the second magnetic layer 8. The magnetic connection between the first magnetic layer 7 and the second magnetic layer 8 can ensure the sealing of the connection gap, effectively ensure good dust and pollution prevention effects, and meet the connection range. More flexible bonding effect, more convenient and quick operation.
