Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a hole position adjustable incision protector. Background Art

[0002] During abdominal surgery, an incision is made in the patient's abdomen, and then the anterior laparoscope and surgical instruments are inserted through the incision to perform the operation. During this process, the incision in the patient's abdomen needs to be protected to prevent bacteria from entering the open incision during the operation and causing infection of the incision section and internal organs. Currently, a combination of an incision protection cover and a port protection cover is used to protect the incision. The incision protection cover protects the incision, and the port protection cover seals the surgical instruments.

[0003] Existing incision protectors seal surgical instruments through sheaths, but the sheaths are fixed to the incision protector cover and the holes cannot be moved. Laparoscopic instruments will restrict each other during use, making smooth operation difficult. Therefore, a hole-adjustable incision protector is proposed. Utility Model Content

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Reference Figure 1-8 A hole position adjustment type incision protector includes an operating cover plate 1, guide rails 2 are opened on both sides of the operating cover plate 1, a clamping head 3 is fixedly connected to the bottom of the operating cover plate 1, a positioning slider 4 is arranged in the guide rail 2, an adjustment component is arranged in the positioning slider 4, an elastic membrane 5 is fixedly connected to the bottom of the inner side of the operating cover plate 1, an intermediate sleeve 6 is provided at the bottom end of the operating cover plate 1, pipes 7 are arranged on both sides of the intermediate sleeve 6, and an incision protection sleeve 8 is sleeved on the bottom of the intermediate sleeve 6.

[0026] Furthermore, a twist cap 9 is provided at the top of the positioning slider 4, and the bottom end of the twist cap 9 passes through the positioning slider 4 and is fixedly connected to a pressure block 10. A square hole 11 is provided on one side of the positioning slider 4 corresponding to the outer guide rail 2, and a buckle 12 is rotatably connected to one side of the square hole 11. A column 13 is provided on the other side of the square hole 11, and a silicone block 14 is fixedly connected to one side of the buckle 12 corresponding to the square hole 11, and a socket 15 is fixedly connected to the buckle 12 corresponding to the column 13.

[0027] A further advantage of adopting the above method is that the adjustment component can be driven to move by sliding the positioning slider 4 along the guide rail 2, the adjustment component can be positioned by tightening the torque cap 9, and the positioning slider 4 can be fixed by closing the buckle 12, thereby achieving a positioning effect.

[0028] Furthermore, the adjustment component includes a slide bar 16, one end of the slide bar 16 is fixedly connected to a movable sheath 17, the other end of the slide bar 16 is fixedly connected to a baffle 18, a positioning groove 19 is provided at the top of the slide bar 16 corresponding to the pressure block 10, a protective cover 20 is clamped on the top of the movable sheath 17, and a protective film 21 is fixedly connected to the inside of the protective cover 20.

[0029] A further advantage of adopting the above method is that the movable sheath 17 is pulled so that the movable sheath 17 slides in the positioning slider 4 through the slide bar 16, and the membrane tube 22 is driven by the movable sheath 17 to move relatively freely under the elastic force of the elastic membrane 5, thereby realizing the function of freely adjusting the working hole position.

[0030] Furthermore, a membrane tube 22 is provided on the surface of the elastic membrane 5 corresponding to the movable sheath 17 , and a reinforcement ring 23 is fixedly connected to the inner wall of the bottom of the membrane tube 22 .

[0031] It should be noted that the height from the bottom to the top of the membrane tube 22 is greater than the length of the movable sheath tube 17. During assembly, after the membrane tube 22 is inserted into the movable sheath tube 17, the top of the membrane tube 22 is manually flipped over so that the top of the membrane tube 22 covers the top of the movable sheath tube 17. Finally, the protective sleeve 20 is installed and the membrane tube 22 is fixed by the protective sleeve 20.

[0032] A further advantage of adopting the above method is that, by providing the reinforcement ring 23 , the membrane hole will not be deformed when being driven by the movable sheath 17 , thereby allowing surgical instruments to pass through the incision protector normally.

[0033] Furthermore, a slot 24 is provided on the top of the intermediate sleeve 6 and an annular groove 25 is provided on the outer wall of the bottom of the intermediate sleeve 6. The outer diameter of the annular groove 25 is larger than the outer diameter of the incision protection sleeve 8, so that the incision protection sleeve 8 can be stably fixed.

[0034] When the present invention is used, the operating cover 1 is inserted into the card slot 24 of the intermediate sleeve 6 through the clamping head 3 at the bottom end to complete the assembly, and the incision protection sleeve 8 is placed into the patient's body through the incision. Then, the outer ring of the incision protection sleeve 8 is sleeved on the annular groove 25 of the intermediate sleeve 6. Because the outer diameter of the annular groove 25 is larger than the outer ring of the incision protection sleeve 8, the incision protection sleeve 8 can be stably fixed on the bottom of the intermediate sleeve 6.

[0035] During surgery, the positioning slider 4 is pulled according to actual conditions to make the positioning slider 4 slide along the guide rail 2, and the movable sheath 17 is pulled to make the movable sheath 17 slide in the positioning slider 4 through the slide bar 16. When the movable sheath 17 moves, the protective sleeve 20 and the reinforcement ring 23 drive the membrane tube 22 to move relatively freely through the elastic force of the elastic membrane 5. When the membrane tube 22 moves, the reinforcement ring 23 is used to ensure that the membrane hole will not be deformed, so that surgical instruments can pass through the membrane tube 22 normally. After adjusting to the appropriate position, tighten the twist cap 9 to tighten and fix the pressure block 10. The fixed slide 16 closes the buckle 12, and the buckle 12 is fixed by the engagement of the base 15 with the column 13. After the buckle 12 is engaged, the silicone block 14 is tightly against the guide rail 2, and the friction between the silicone block 14 and the guide rail 2 prevents the positioning slider 4 from moving. By arranging the pipe 7 at the bottom of the operating cover 1, pneumoperitoneum can be established and smoke generated during the operation can be discharged without affecting the operation of the adjustment component, realizing the function of freely adjusting the hole position of the incision protector and fixing it, avoiding mutual restriction of laparoscopic instruments during use, and thus achieving the effect of smooth operation of surgical instruments.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
