This utility model is a liver retractor gold finger, comprising a handle, an adjusting handwheel, an adjusting screw, a steel wire rope, and a deformable retractor; the adjusting handwheel is rotatably connected to the end of the handle, and the adjusting screw is disposed inside the handle and threadedly connected to the adjusting handwheel; the deformable retractor is fixed to the front end of the handle, and the deformable retractor includes a first straight rod, a first movable part, a second straight rod, a second movable part, a third straight rod, a third movable part, a fourth straight rod, and a fourth movable part connected sequentially from front to back by the steel wire rope; the end of the steel wire rope is connected to the adjusting screw, and when the steel wire rope is tightened, the first straight rod, the first movable part, the second straight rod, the second movable part, and the third straight rod form a circular area. This utility model relates to a liver retractor gold finger...

[0004] It can be inserted into the body, making it easy to operate. It is not easy to fall off when pulling internal organs, which helps to protect the pulled internal organs and avoid damage to them.

[0005] Although this utility model makes the traction of internal organs more stable by setting up a multi-part deformable hook, it still needs to be bent when traction of tissues and organs, and there are still certain requirements on the size of the incision that serves as the exit. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems by providing an adjustable collection device that can remove the tissues and organs to be taken out without bending the surgical instruments, thereby further reducing the size of the patient's wound.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] This utility model relates to an adjustable collection device, such as... Figure 1 As shown, it includes a storage bag 1; one end of the storage bag 1 is also connected to a movable joint assembly 2 that can change the opening degree of the storage bag opening 11, one end of the movable joint assembly 2 is fixedly connected to a control handle 3, and the control handle 3 is also provided with a bending control assembly 4 for driving the movable joint assembly 2 to bend, one end of the bending control assembly 4 extends into the movable joint assembly 2.

[0029] In use, the movable joint assembly 2 is inserted into the opening 11 of the storage bag, and the handle 3 is operated to bend the movable joint assembly 2 to shrink the opening 11 of the storage bag, thereby changing the degree of opening and closing of the opening 11 of the storage bag.

[0030] Preferred, such as Figures 1-2 As shown, by providing at least one side of the storage bag opening 11 with a double-layer structure and a cavity 111 inside the double-layer structure, one end of the movable joint assembly 2 can be inserted into the cavity 111 to drive the storage bag opening 11 to open and close.

[0031] Preferred, such as Figure 1 , 4 As shown, the bending control assembly 4 includes a traction assembly 41 and a force transmission component 42. The traction assembly 41 pulls the force transmission component 42 to drive the movable joint assembly 2 to bend.

[0032] Preferred, such as Figure 3 , 4 As shown, the force transmission component 42 includes a steel wire rope 421 and a traction channel 422. The traction channel 422 connects and extends through the movable joint assembly 2 and the bending control assembly 4. The steel wire rope 421 is disposed inside the traction channel 422 and is connected to the movable joint assembly 2 at least once. A similar file manipulation method as described in the prior art can be used, where initially the steel wire rope has extra segments at each bending point. Pulling the steel wire rope 421 causes the end of the movable joint assembly 2 away from the traction device to move closer to the bending control assembly 4, thus producing a bending effect.

[0033] Preferably, the traction assembly 41 includes a rotating traction seat 411 and a rotating base 412. The rotating traction seat 411 moves closer to or further away from the movable joint assembly 2 when it rotates in a threaded fit with the rotating base 412. When it moves away, it can drive the wire rope.

[0034] Specifically, such as Figure 1 , 7 As shown, the movable joint assembly 2 includes a bending portion 21 and a fixing portion 22. The bending portion 21 rotates under the traction of the force transmission component 42 to achieve an overall groove-shaped bending effect. It is easy to imagine that to achieve the effect of shrinking the opening 11 of the storage bag, there must be at least two bending portions 21 and at least three fixing portions 22. As shown, for smoother bending, the bending portion can be composed of multiple small, rotatable parts.

[0035] Preferably, since the wire rope 421 has no memory function, an alternative method is needed to restore the movable joint assembly 2 from a bent state to a straight state. Therefore, the bending control assembly 4 also includes a return assembly 43, which restores the force transmission component 42 to a non-traction state when the traction assembly 41 does not provide traction force.

[0036] Specifically, such as Figure 3 As shown, the aforementioned recovery component 43 includes a nickel-titanium wire 431 and a recovery channel 432. The recovery channel 432 is connected and extends through the interior of the movable joint component 2. The nickel-titanium wire 431 has memory properties and can generate anti-deformation force when the movable joint component 2 is bent. When the steel wire rope 421 no longer provides traction force, it recovers its deformation and drives the movable joint component 2 to return to straightness.

[0037] Preferably, to improve efficiency and save materials, the movable joint component 2 is U-shaped in its maximum bending state.

[0038] Preferred, such as Figure 1 , 3 As shown in Figure 4, it also includes a rinsing device 5 and a rinsing channel 6. The rinsing channel 6 connects the movable joint assembly 2 and the control handle 3, and has an outlet at the end of the movable joint assembly 2 away from the control handle 3. The rinsing device 5 is mounted on the control handle 3 and connected to the rinsing channel 6. Figure 3 , 4 As shown, the flushing channel 6 is arranged side by side with other components, such as... Figure 1 , 4 As shown, water is injected into the flushing channel 6, which is formed by the flushing water pipe of the control handle 3, and then cleaned until it exits at one end of the movable joint component 2 (postoperative flushing). Various orifices are opened along the flushing channel 6 to clean the entire process.

[0039] The working principle of this utility model is as follows: the movable joint component 2 is fitted into the cavity 111 of the opening 11 of the storage bag, such as... Figure 5 As shown in the diagram, the movable joint assembly 2 is inserted into the surgical opening in a straight position. Upon reaching the edge of the tissue to be removed, the traction component 41 on the operating handle 3 is operated. For example, the rotating traction seat 411, screwed backward onto the rotating base 412, drives the steel wire rope 421 to apply traction to one end of the movable joint assembly 2. After traction begins, the spacing between the steel wire ropes 421 between the bending portions 21 is gradually reduced, causing each part of the bending portion 21 to rotate, thus achieving the overall bending effect of the movable joint assembly 2. The bending of the movable joint assembly 2 causes the storage bag 1 to contract, preferably bending into a U-shape, to enclose the target tissue, such as... Figure 6 As shown in the diagram. Twisting the traction seat 411 forward loosens the steel wire rope. The deformation-resistant force of the nickel-titanium wire 431 presses against the inner wall of the return channel 432, causing the movable joint assembly 2 to return to a straight state and act as a barrier against the tissue inside the storage bag 1. Then, the movable joint assembly 2 is removed from the wound by manipulating the handle 3. After removal, the storage bag 1 is taken out, and clean water at a certain pressure is injected into the flushing channel 6 through the flushing device 5. The flushing channel 6 has numerous gaps along its path to flush the manipulator 3 and the movable joint assembly 2.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0041] Although this document frequently uses terms such as storage bag 1, movable joint assembly 2, operating handle 3, bending control assembly 4, rinsing device 5, rinsing channel 6, storage bag opening 11, cavity 111, bending part 21, fixing part 22, traction assembly 41, rotating traction seat 411, rotating base, force transmission component 42, wire rope 421, traction channel 422, return assembly 43, nickel-titanium wire 431, and return channel 432, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
