Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention.

Referring to fig. 1-2, a surgical retractor 100 is used to retract tissue and expose the operative field during operation.

The surgical retractor 100 comprises a fixing ring 1 and a plurality of draw hooks 2, wherein the fixing ring 1 is annular and is provided with a plurality of positioning holes 11 at intervals along the circumferential direction, and the draw hooks 2 are selectively arranged on the positioning holes 11 at different positions.

In a preferred embodiment, the fixing ring 1 is provided with 8 positioning holes 11, and the interval angle between two adjacent positioning holes 11 is the same, namely 45 °.

It should be noted that a plurality of the drag hooks 2 are arranged on the positioning holes 11 at different positions, so as to preliminarily define the circumferential range of the operation.

It should be noted that 8 drag hooks 2 can be installed on 8 positioning holes 11, and 3, 4, etc. drag hooks 2 can also be installed according to practical situations. For example, only four hooks 2 are shown in fig. 1.

The drag hook 2 is provided with a hook body 21 and an absorbing device 22, the hook body 21 is provided with a connecting end 211 and a fixed end 212, a plurality of positioning columns are formed on the lower end surface of the connecting end 211 along the length direction, the positioning columns can be rotatably inserted into different positioning holes along the horizontal direction, so that the extending lengths of the fixed end 212 relative to the fixed ring 1 are different, the fixed end 212 can prop open tissues, and the operation range is further limited; the fixed end 212 is formed with a strip hole 2120 along a length direction, a rear end of the suction device 22 is rotatably connected to one end of the strip hole 2120 along a vertical direction, and a front end of the suction device 22 is used for absorbing blood.

It should be noted that the fixed ends 212 of the hook bodies 21 finally define the operation range, and the suction device 22 is rotatably disposed at one end of the strip-shaped hole 2120, so as not to affect the limited range of the fixed ends 212, and can absorb and clean blood stains when rotating a certain angle, and can contact human tissues and stop cleaning blood stains when rotating other angles.

The absorbing device 22 is rotatably connected in the bar-shaped hole 2120 by a damping rotating shaft 23, and the absorbing device 22 can rotate outwards by a certain angle relative to the bar-shaped hole 2120 by the damping rotating shaft 23 and stop freely within the angle range.

It should be noted that the range of the rotation angle of the absorbing device 22 is defined as follows: rotate clockwise between 0 and 60 degrees relative to the horizontal plane of the strip-shaped holes 2120. That is, the getter device 22 can be rotated outward by 60 ° with respect to the fixed end and can be stopped at any position, and when the angle between the getter device 2 and the horizontal plane where the strip hole 2120 is located is 0 °, it is located in the strip hole 2120. The rotation angle of the absorbing device 22 is used to control the switching of the absorbing device 22 between the state of absorbing the blood stain and the state of stopping absorbing the blood stain.

For example, the manual dialing now swings the getter device 22 by 30 ° at 22, at which point the applied force is removed and the getter device 22 can stop at that angle, so as not to interfere with the surgical procedure.

As shown in fig. 3, the suction device 22 includes a holder 221 and a medical cotton 222, the holder 221 is a tube type whose outer wall is connected to the movable end of the damping shaft 23, the medical cotton 222 is replaceably disposed in the holder 221, and when the front end (the end far from the connecting end) of the holder 221 is close to the tissue, tissue fluid or blood can be sucked into the medical cotton 222 by a siphon action.

Note that the medical cotton 222 is inserted into the jig 221.

It should be noted that the damping rotating shaft 23 is disposed on one side of the strip-shaped hole 2120 close to the connecting end 211, and the rear end (one end close to the connecting end) of the clamp 221 is connected to the damping rotating shaft 23.

Preferably, the front end of the clamp 221 is extended in a length direction and tapered to be more tapered to better absorb blood.

The working principle of the utility model is as follows: the fixing ring 1 is arranged on the periphery of the tissue, the connecting ends 211 of the draw hooks 2 are fixed on a certain positioning hole, the draw hooks 2 are arranged along the circumferential direction of the fixing ring 1, the fixing end 212 finally limits the outward expansion range of the tissue, the front end of the absorbing device 22 swings relative to the rear end of the absorbing device, the front end of the clamp 221 of the absorbing device 22 can contact with blood, the clamp 221 is timely absorbed, the clamp 221 swings after the blood is completely absorbed, the clamp 221 is not contacted with the tissue, the body fluid or the blood is prevented from being absorbed all the time, and when the blood absorbed by the medical cotton 222 reaches a certain degree, the medical cotton 222 can be extracted from the clamp 221.

The above-mentioned embodiments only express the embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
