[0019] The utility model discloses an embodiment of the utility model will be described below with the drawings of the utility model embodiment Figures 1-4 The technical scheme in the embodiment of the utility model is described in detail. Embodiment 1

[0020] As Figures 1-4 The utility model discloses a disposable annular surgical automatic retractor device, including fixed seat 1, limiting piece 2 and retractor assembly 3.

[0021] As Figures 1-2 Fixed seat 1 is annular, and the middle is provided with a hole for exposing the surgical field of view, and the bottom of fixed seat 1 is fixedly provided with adhesive 4, and the adhesive 4 is used for being adhered on the surgical drape around the surgical incision to fix the device.

[0022] A plurality of fixed holes 11 are uniformly arranged on the peripheral edge of the upper surface of fixed seat 1, and the fixed holes 11 are used when the device cannot be fixed by the adhesive 4, and are matched with the towel forceps to fix the device and the surgical drape around the surgical incision.

[0023] The edge of the middle opening of fixed seat 1 is upwardly protruded to form a plurality of guide columns 13 for turning the retractor assembly 3, and the guide columns 13 are cylindrical, and the distance between the adjacent two guide columns 13 is sufficient for the retractor assembly 3 to pass through.

[0024] A plurality of fixed rings 12 are fixedly installed on the side wall of fixed seat 1, the fixed ring 12 is connected with the retractor assembly 3, the retractor assembly 3 is connected with the fixed seat 1, and the number of the fixed ring 12 on each fixed seat 1 is four, that is, the number of the retractor assembly 3 on each fixed seat 1 is also four.

[0025] Of course, the fixed ring 12 can be connected with the side wall of the fixed seat 1 through threads, at this time, the retractor assembly 3 and the fixed ring 12 are an integral structure, and the fixed seat 1 is an integral body, and only the fixed ring 12 needs to be threadedly connected with the fixed seat 1, so that the assembly of the device can be realized.

[0026] As Figure 3The limiting piece 2 is installed on the upper surface of the fixed seat 1, and the limiting piece 2 and the fixed seat 1 are an integral structure, of course, the two can also be connected into an integral structure by a screw rod and the like, the number of the limiting piece 2 is also four, and the limiting piece 2 extends along the radial direction of the fixed seat 1.

[0027] A plurality of grooves 21 are uniformly arranged on the upper surface of the limiting piece 2, the grooves 21 also extend along the radial direction of the fixed seat 1, the grooves 21 are used for clamping the hook assembly 3, limiting the length of the movable part of the hook assembly 3, and then adjusting the hook assembly 3, so that the surgical field can be maximally exposed during traction.

[0028] The cross section of the groove 21 is in the shape of an inverted "Ω", after the hook assembly 3 is clamped into the groove 21, since the opening of the groove 21 is small and the inner cavity is large, the hook assembly 3 is not easy to come out, and the stability during traction is improved.

[0029] A rope groove 22 is further arranged in the middle of the upper surface of the limiting piece 2, and the rope groove 22 is used for auxiliary fixing and further improving the stability.

[0030] As shown in the drawings, the hook assembly 3 is installed on the side wall of the fixed seat 1 through a fixing ring 12, and the number of the hook assembly 3 is consistent with the number of the limiting piece 2. Figure 4

[0031] The hook assembly 3 includes a spring rope 31 and a metal hook 32, one end of the spring rope 31 is fixedly connected with the metal hook 32, and this end is the movable end of the spring rope 31, the other end of the spring rope 31 is fixedly connected with the fixing ring 12, and this end is the fixed end of the spring rope 31.

[0032] A plurality of protrusions 33 for fixing and limiting are distributed on the spring rope 31, the shape of the protrusion 33 is matched with the groove 21, preferably, the protrusion 33 can be realized by knotting the spring rope 31 and the like, and it should be noted that the protrusions 33 are uniformly distributed.

[0033] The spring rope 31 is matched with the rope groove 22, the spring rope 31 can be clamped into the rope groove 22, auxiliary fixing is performed, and the stability during traction is improved.

[0034] In use, by clamping the protrusion 33 in the middle into the suitable groove 21, the length of the movable end of the spring rope 31 is adjusted, it is ensured that the movable end of the spring rope 31 can pull the wound without causing secondary injury, and the surgical field can be maximally exposed.

[0035] ​At the same time, the protrusion 33 at the end is also clamped into the corresponding groove 21, at this time the fixed end of the elastic cord 31 does not have elastic deformation, and the movable end can be clamped into the cord groove 22, further assisting fixation, improving stability, and since it is clamped into the cord groove 22, it is not easy to be pulled and moved, causing the protrusion 33 to be separated from the groove 21, and affecting the pulling of the surgical incision.

[0036] The metal retractor 32 is made of stainless steel, which is easy to obtain, convenient to process, and low in price, and the one-time use cost is low.

[0037] The use method of the one-time annular surgical automatic retractor device of the embodiment is as follows:

[0038] Take four fixed rings 12 connected with the retractor assembly 3, install the fixed ring 12 on the side wall of the fixed seat 1 in sequence through threads, then fix and bond the device on the surgical drape around the surgical incision through the adhesive 4 at the bottom of the fixed seat 1, then according to the need, pass the elastic cord 31 of the four retractor assemblies 3 between the guide columns 13 at appropriate positions, so as to adjust the direction of the final pulling, pinch the protrusion 33 in the middle, and clamp it into the appropriate groove 21 along the direction of the fixed seat 1, so as to ensure that the incision is not secondarily damaged, while maximizing the exposure of the surgical field, then clamp the protrusion 33 close to the fixed ring 12 into the corresponding groove 21, at this time the fixed end of the elastic cord 31 does not have elastic deformation and is clamped into the cord groove 22, then sequentially complete the above operation on all the retractor assemblies 3, the device installation is completed, and subsequent surgical operation can be performed, after the operation is completed, the elastic cord 31 is loosened, the pulling of the incision by the metal retractor 32 is cancelled, and the whole device is discarded.

[0039] The above embodiments only illustrate the technical idea of the present application, and cannot limit the protection scope of the present application, and any modification made on the basis of the technical scheme according to the technical idea of the present application falls within the protection scope of the present application.
