Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Please see Figure 1 , Figure 2 and Figure 3As shown in the figure, this utility model embodiment discloses an integrated device for fixing, observing and dividing postoperative specimens. As a specific application scenario of this utility model, it can be used to fix, observe and divide postoperative specimens of endoscopic submucosal dissection. The integrated device includes a specimen fixing groove, a movable side plate 4 and an observation mechanism 7. The specimen fixing groove includes a base plate 1 and two horizontal plates 2 and two vertical plates 3 extending vertically upward along the edge of the base plate 1. The base plate 1, the two horizontal plates 2 and the two vertical plates 3 together form a rectangular groove structure.

[0020] The movable side plate 4 is set inside the specimen fixing groove. The movable side plate 4 is slidably connected to the two horizontal plates 2 of the specimen fixing groove through a sliding device, so that the movable side plate 4 can slide between the two vertical plates 3 parallel to it.

[0021] Specifically, the sliding device includes a pair of parallel grooves 401 and a pair of sliders. In this embodiment, the grooves 401 are T-shaped grooves, and the pair of grooves 401 are respectively embedded in the upper middle part of the inner sidewall of the two horizontal plates 2. The sliders are T-shaped sliders that match the grooves 401. The pair of sliders are respectively fixedly disposed on the side surface of the movable side plate 4 parallel to the corresponding horizontal plate 2. As one embodiment, the movable side plate 4 with sliders is placed inside the specimen fixing groove during factory assembly, and each slider is correspondingly disposed in the groove 401 on the inner sidewall of the two horizontal plates 2, ensuring that the movable side plate 4 can slide freely in the specimen fixing groove.

[0022] Preferably, the movable side plate 4 is further provided with a pair of locking mechanisms 5, which are used to fix the relative position of the movable side plate 4. Each locking mechanism 5 and each slider are located on the same side of the movable side plate 4, and each locking mechanism 5 is located above the corresponding slider.

[0023] Specifically, each locking mechanism 5 includes a spring 501, a locking block 502, and a lever 503. The movable side plate 4 is provided with a groove on the side surface parallel to the horizontal plate 2. One end of the spring 501 abuts against the bottom of the groove, and the other end of the spring 501 abuts against one end of the locking block 502. The end of the locking block 502 away from the spring 501 abuts against the inner wall of the corresponding horizontal plate 2. As one embodiment, the end of the locking block 502 that abuts against the inner wall of the horizontal plate 2 is attached with an anti-slip rubber top.

[0024] The movable side plate 4 has an operating opening on one side perpendicular to the groove setting surface. The length of the operating opening is less than the length of the groove. One end of the lever 503 is fixedly connected to the side wall of the locking block 502, and the other end of the lever 503 can extend along the operating opening. When medical staff need to slide the movable side plate 4, they can move the lever 503 to compress the locking block 502 and retract the spring 501. At this time, the lock is released, and the movable side plate 4 can move in the specimen fixing groove. When the movable side plate 4 moves to the predetermined position, the lever 503 is released, the spring 501 releases its elastic force, and pushes the end of the locking block 502 with the anti-slip rubber top to abut against the inner side wall of the horizontal plate 2 to achieve locking.

[0025] Preferably, a sealing strip 402 is provided on the side of the movable side plate 4 that contacts the bottom plate 1. The sealing strip 402 is used to prevent liquid leakage inside the specimen fixing groove.

[0026] The specimen fixing slot has scale lines 10 on the inner wall of the horizontal plate 2 and on the surface of the movable side plate 4. The scale lines 10 are used to measure the size of the specimen.

[0027] Specifically, the scale lines 10 on the inner side wall of the horizontal plate 2 of the fixing groove and the scale lines 10 on the movable side plate 4 are both set on the side of the corresponding horizontal plate 2 and movable side plate 4 facing the specimen, and the scale lines 10 are closer to the open side of the specimen fixing groove.

[0028] Preferably, the present invention also includes a marking structure for visual orientation of postoperative specimens.

[0029] In this embodiment, the marking structure includes a slot 6 and an insert plate 601. The slot 6 is located on the upper edge of the two vertical plates 3 and the two horizontal plates 2. A connecting rod is fixed on one side of the insert plate 601. The connecting rod can be inserted into the slot 6. After the operation, medical staff can immediately record the internal orientation of the specimen (such as the oral side or anal side) on the insert plate 601 and insert the insert plate 601 into the corresponding slot 6 on the specimen fixing groove to prevent the loss of orientation information after the specimen is removed from the body, ensure that the anatomical orientation of the specimen is always correct, and avoid affecting the judgment of the specimen cutting edge status.

[0030] The observation mechanism 7 is fixedly connected to one of the horizontal plates 2 or one of the vertical plates 3 of the specimen fixing slot. The observation mechanism 7 is used to observe the specimen in the specimen fixing slot.

[0031] Specifically, the observation mechanism 7 is a cantilever observation mechanism, which includes a rotating base 701, a first arm 702, a second arm 703, and a clamping component 704. The rotating base 701 is fixedly connected to the outer wall of one of the longitudinal plates 3 or one of the transverse plates 2 of the specimen fixing groove. In this embodiment, the rotating base 701 is bonded to the outer wall of its corresponding transverse plate 2. The rotating base 701 is a damped rotating base, which can drive the first arm 702 to rotate around the center of the rotating base 701. One end of the first arm 702 is hinged to the rotating base 701 through a damping pivot, which can adjust the angle between the first arm 702 and the outer wall of its corresponding transverse plate 2.

[0032] The second arm 703 is a telescopic arm. One end of the second arm 703 is also hinged to the end of the first arm 702 away from the rotating base via a damping pivot. The pitch angle of the second arm 703 can be adjusted via the damping pivot. The other end of the second arm 703 is a ball joint. The clamping component 704 is rotatably connected to the second arm 703 via the ball joint. The ball joint allows the clamping component 704 to rotate in different directions. The clamping component 704 is selected to match the clamping component 704 of a magnifying glass or a camera.

[0033] Preferably, the bottom plate 1 of the specimen fixing groove is provided with an elastic fixing layer 8, which is laid on the upper surface of the bottom plate 1 of the fixing groove.

[0034] In this embodiment, the elastic fixing layer 8 is a thin foam pad.

[0035] Preferably, a drain port 9 is provided on the side wall of one of the longitudinal plates 3 or one of the transverse plates 2 of the specimen fixing tank, and a valve is also provided on the drain port 9. Specifically, a drain port 9 is provided at the bottom of one of the transverse plates 2 of the specimen fixing tank. The drain port 9 is used to drain the liquid in the specimen fixing tank without moving the specimen. The valve is a plug valve.

[0036] The specific usage of this utility model is as follows: During the preparation phase, medical staff first estimate the specimen size. Then, based on the specimen size, they move lever 503 to release the locking mechanism 5 and slide the movable side plate 4 to the predetermined position before locking it. A thin foam pad is then placed on the bottom plate 1 of the specimen fixation tank. Finally, the observation equipment is connected to the observation mechanism 7. During the actual operation, the specimen is placed on the thin foam pad, and the specimen location is recorded on the insert plate 601. The insert plate 601 is then inserted into the slot 6. Formalin fixative is poured into the specimen fixation tank, and the observation equipment is adjusted for observation. The valve at the drain port 9 is then opened to drain the fixative. Finally, the specimen is segmented, and its dimensions are recorded.
