The technical problem to be solved by the present invention is to provide a novel sterile sleeve for a surgical robot, aiming at the above-mentioned defects of the prior art.

The technical scheme adopted by the utility model for solving the technical problems is as follows:

the novel sterile sleeve for the surgical robot is constructed and comprises a sterile sleeve body; the sterile sleeve body is provided with an opening for the surgical instrument to penetrate; wherein the novel sterile sleeve further comprises a sealing assembly; the sealing assemblies correspond to the openings one by one;

the sealing assembly comprises an outer magnetic ring and an inner iron ring which are matched; a sealing rubber ring is fixedly sleeved on the inner iron ring; the inner circular surface of the outer magnetic ring is provided with a sealing groove matched with the sealing rubber ring; the inner wall of the inner iron ring is fixedly bonded with the outer surface of the sterile sleeve body; the seal assembly further comprises an annular sterile membrane; both ends of the sterile film are fixed with the outer surface of the sterile sleeve body; the sterile film is matched with the sterile sleeve body to completely wrap the inner iron ring and the sealing rubber ring; the outer magnetic ring is sleeved on a flange plate at the tail end of the surgical robot and is fixed with the flange plate.

Preferably, the inner surface of the sterile film is coated with magnetic powder staggered with the inner iron ring; the magnetic powder corresponds to the outer magnetic ring.

Preferably, the sterile membrane is integrally formed with the sterile sleeve body.

Preferably, the inner iron ring is provided with a positioning groove matched with the sealing rubber ring.

Preferably, the inner wall of the end of the outer magnetic ring, into which the inner iron ring is inserted, is provided with a chamfer.

The utility model has the beneficial effects that: the sealing effect is better, and the condition that viruses or bacteria spread outwards is effectively reduced. Specifically, the outer magnetic ring is fixed on a flange plate at the tail end of the surgical robot, and then the sterile sleeve body is sleeved on a movable arm of the surgical robot; and then, insert the interior iron ring in the outer magnetic ring, until the rubber gasket card of seal is gone into in the seal groove, can support the sterile film on outer magnetic ring, simultaneously, the tip of interior iron ring also supports the sterile film on the ring flange, has realized double seal, finally, can with the surgical instrument fixed to the ring flange.

FIG. 1 is a schematic view (in section) of the use of the novel sterile sleeve for a surgical robot in accordance with the preferred embodiment of the present invention;

fig. 2 is an enlarged view at a in fig. 1.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without inventive step, are within the scope of the present invention.

Fig. 1-2 show a novel sterile sleeve for a surgical robot according to a preferred embodiment of the present invention, which comprises a sterile sleeve body 10; the sterile sleeve body 10 is provided with an opening 180 for the surgical instrument to penetrate through, and the novel sterile sleeve also comprises a sealing component 11; the seal assemblies 11 correspond one-to-one with the openings 180;

the sealing assembly 11 comprises an outer magnetic ring 12 and an inner iron ring 13 which are matched; a sealing rubber ring 14 is fixedly sleeved on the inner iron ring 13; the inner circle surface of the outer magnetic ring 12 is provided with a sealing groove 181 matched with the sealing rubber ring 14; the inner wall of the inner iron ring 13 is fixedly bonded with the outer surface of the sterile sleeve body 10; the sealing assembly 11 further comprises an annular sterile membrane 15; both ends of the sterile film 15 are fixed with the outer surface of the sterile sleeve body 10; the sterile film 15 is matched with the sterile sleeve body 10 to completely wrap the inner iron ring 13 and the sealing rubber ring 14; the outer magnetic ring 12 is sleeved on the flange 2 at the tail end of the surgical robot and fixed with the flange.
