As shown in fig. 1 to 3, a surgical retractor for minimally invasive eyelid comprises a retractor body, wherein a support piece is detachably connected to the bottom of the retractor body, a clamping piece 9 is arranged at one end, away from the retractor body, of the support piece, and the clamping piece 9 is clamped and fixed to an operating bed or other fixed objects when being used for surgical implementation, so that the surgical retractor is not required to be held by an assistant doctor, and operation is greatly facilitated.

Specifically, support piece is including being used for connecting the connecting portion 6 of drag hook body and the pars contractilis 7 of setting in the 6 bottoms of connecting portion, and wherein the one end that connecting portion 6 were kept away from to pars contractilis 7 is provided with connecting piece 8, and connecting piece 8 is used for being connected with holder 9. In this embodiment, the telescopic portion 7 is in the form of a telescopic shaft, and the telescopic portion 7 may include a first shaft and a second shaft, wherein the first shaft is telescopically arranged in the second shaft and is finally positioned by a positioning pin.

According to the above scheme, connecting portion 6 is connected behind the drag hook body, and pars contractilis 7 is according to actual height in order to adjust whole support piece's length, makes support piece adapt to the specific height of patient's eyelid to operation table edge, or the specific height of other fixed articles to improve operation drag hook's application scope.

Furthermore, the clamping piece 9 is rotatably connected to the connecting piece 8, so that the clamping piece 9 connected to the connecting piece 8 has multi-directional freedom degree, is convenient to adjust and can be clamped on the edge of an operating table or a guardrail of the operating table; in this embodiment, the connecting member 8 includes a connecting block, a rotating groove (not shown in the figure) is formed on an end surface of the connecting block opposite to the clamping member 9, and a connecting ball (not shown in the figure) is disposed on the clamping member 9 and is rotatably clamped in the rotating groove to achieve the purpose of rotating the clamping member 9. In this embodiment, the clamping member 9 is an a-shaped clamp, but the clamping member 9 may also be a clip with elasticity.

Furthermore, the drag hook body comprises an installation block 3, two opening arms 2 are hinged to the side wall of the installation block 3 at horizontal intervals, an eyelid opening hook 1 is arranged at one end of each of the two opening arms 2 far away from the installation block 3, and the eyelid opening hook 1 is used for opening the eyelid of a patient; installing block 3 wears to be equipped with regulating part 10 dorsad to the lateral wall of opening arm 2, and regulating part 10 is close to the one end threaded connection who opens arm 2 and has sliding block 12, and it has swing rod 13 to correspond articulated with two opening arms 2 respectively on sliding block 12, and the one end that sliding block 12 was kept away from to swing rod 13 articulates on opening arm 2.

Specifically, two placing grooves 31 are arranged on the side wall of the mounting block 3 at intervals, pin shafts 32 are arranged in the placing grooves 31, and the opening arm 2 is rotatably connected to the pin shafts 32.

Through the scheme, the doctor rotates the adjusting piece 10 to drive the sliding block 12 to reciprocate in the horizontal direction until the eyelid of the patient is completely opened, and after the eyelid is opened to a proper position, the doctor stops rotating the adjusting piece 10 because the sliding block 12 is screwed with the adjusting piece 10, and the sliding block 12 is meshed with the screw teeth on the adjusting piece 10 to position the eyelid opening hook 1. Threaded groove (not shown in the figure) has been seted up to the bottom of installation piece 3, and connecting portion 6 threaded connection is in the threaded groove, and no matter be the assembly operation drag hook or dismantle the operation drag hook, the user only needs to screw support piece spiral shell to accomplish in the threaded groove, and convenient operation saves the operation time greatly.

Further, one end of the adjusting member 10, which is away from the sliding block 12, is coaxially provided with a screwing portion 5, two screwing lugs 4 are symmetrically arranged on the outer side surface of the screwing portion 5, and the active physician adjusts the opening degree of the eyelid opening hook 1 by screwing the lugs 4, and in this embodiment, the adjusting member 10 is a screw rod.

For optimization, the adjusting member 10 is sleeved with an elastic member 11, one end of the elastic member 11 abuts against the sliding block 12, and the other end abuts against the mounting block 3. Elastic component 11's setting can be so that sliding block 12 is stronger in the interlock power on regulating part 10, and elastic component 11 makes sliding block 12 and the thread zonulae occludens on regulating part 10 because its self elastic stress, and elastic component 11 also plays the effect of pretension, prevents to appear rocking unstable phenomenon in the adjustment process of operation drag hook.

In this embodiment, the elastic member 11 is a spring.
