Description

Technical Field

[0001] The present invention relates to the field of incision protectors, in particular to an incision protector adapted to small incisions. Background Art

[0002] During a laparotomy, after the doctor opens the patient's surgical site, the incision will be closed due to tissue contraction. In the past, the doctor would use a metal retractor or retractor to pull the incision open after the patient's skin was cut, thereby exposing the surgical field of view. However, excessive retraction often occurs, resulting in tearing of the wound or insufficient exposure angle. Various incision protectors have been developed for clinical use, usually consisting of an outer ring, an insertion ring, and a sleeve-like film between the two. At this stage, the insertion ring of the incision protector is inserted into the incision, and the outer ring remains outside the body, thereby achieving the purpose of opening the incision. The doctor can perform surgery on the patient in the surgical channel formed by the sleeve-like film.

[0003] Traditional incision protectors are generally annular plastic workpieces with an industrial design, so that the incision protector is inserted into the patient's wound. However, the incision protector may cause strain or tearing to the patient's wound when inserted into the wound or removed. Summary of the Invention

[0026] (3) The height of the engaging groove of the present invention is twice that of the pressing block, so when the worker presses the pressing block to the lowest point, the locking block will move to the bottom of the sliding ring, and then the pressing block will be bounced up under the cooperation of the second telescopic rod, the second spring and the support plate. When the sliding ring contacts the top block, the locking block can slide out on the outer wall of the sliding ring and the top block, thereby releasing the limit of the pressing block and facilitating operation.

[0041] Working principle: When in use, the outer shell 3 is inserted into the inner wall of the patient's wound. Since the positions of the outer shell 3, the annular airbag 6 and the bottom ring 4 are corresponding, it is convenient for the outer shell 3 to be inserted into the wound, and the outer ring 1 is in contact with the patient's skin. Then the staff presses the compression block 7, so that the compression block 7 compresses the air inside the compression cylinder 5, and allows the air inside the compression cylinder 5 to enter the annular airbag 6 from the connecting port 10, thereby propping up the annular airbag 6, and then allowing the annular airbag 6 to support the inner side of the patient's wound. When taking it out, the air inside the annular airbag 6 returns to the inside of the compression cylinder 5, so that the annular airbag 6 is reset, and then the limit is released. It is simple to operate and easy to take out, and will not cause strain or tearing to the wound, and the compression block 9 can slide the locking block 14 to the bottom of the top block 17 to play a locking role, and when the locking block 14 slides on the outer wall of the top block 17, the first telescopic rod 12 and the first spring 13 can play a telescopic reset role. When the pressure block 9 is reset, it is necessary to press the pressure block 9 again, and the height of the clamping groove 8 is twice that of the pressure block 9. Therefore, when the staff presses the pressure block 9 to move to the lowest point, the locking block 14 will move to the bottom of the sliding ring 18, and then the pressure block 9 will be bounced up under the cooperation of the second telescopic rod 19, the second spring 21 and the support plate 20. When the sliding ring 18 contacts the top block 17, the locking block 14 can slide out on the outer wall of the sliding ring 18 and the top block 17, thereby releasing the limit of the pressure block 9 and making the operation convenient.
