DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The embodiment of the present application provides a scalpel with a self-replaceable and disinfectable blade, which solves the problem that during installation and disassembly, surgical forceps are needed to deform the blade 3 and insert it into the handle 1 for clamping, resulting in the inability to quickly disassemble the blade 3. The pull block 401 is pulled so that the pull block 401 pushes the lower mounting seat 301 to move. Under the movement of the lower mounting seat 301, the blade 3 moves outward. At this time, the position of the blade 3 is only limited by the limit seat 303, so it can be quickly disassembled. When the disinfection cover 2 is sleeved on the handle 1, the blade 3 is pushed outward and can be inserted into the disinfection cover 2 to disinfect the blade 3.

[0034] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] The embodiment of the invention discloses a surgical knife with a self-replaceable and sterilizable blade.

[0036] According to the attached Figure 1-9 As shown, it comprises a handle 1 and a blade 3. The outer surface of the handle 1 is provided with a disinfection component, and the disinfection component is filled with disinfectant to disinfect the blade 3;

[0037] The handle 1 is provided with a lower mounting seat 301 and an upper mounting seat 302, and a mounting assembly is provided between the lower mounting seat 301 and the upper mounting seat 302, and the mounting assembly can quickly install and disassemble the blade 3;

[0038] A limit assembly is provided inside the handle 1, and the limit assembly controls the movement of the blade 3 to sterilize or disassemble the blade 3;

[0039] An anti-accidental touch component is arranged on the outer surface of the handle 1 , and the anti-accidental touch component can prevent the blade 3 from moving due to an accidental touch, thereby avoiding affecting the use of the blade 3 .

[0040] The outer surface of the knife handle 1 is provided with a knife groove 102 , which facilitates stable holding of the knife handle 1 .

[0041] The disinfection assembly includes a disinfection cover 2, which is sleeved on the outer surface of the knife handle 1. A disinfection interlayer 201 is arranged inside the disinfection cover 2. The disinfection interlayer 201 cooperates with the disinfection cover 2 to store disinfectant in the disinfection cover 2 and the disinfection interlayer 201. The blade 3 is inserted into the disinfection cover 2 by piercing the disinfection interlayer 201. The blade 3 can be disinfected by the disinfectant in the disinfection interlayer 201 and the disinfection cover 2, so that the blade 3 can be disinfected. Rapid and comprehensive disinfection can be achieved during surgery.

[0042] The outer surface of the knife handle 1 is connected to the upper mounting seat 302, and the knife handle 1 is slidably connected to the lower mounting seat 301. The mounting assembly includes a limit seat 303, a push block 304 and a limit frame 305. The limit seat 303 and the push block 304 are both located on the upper surface of the lower mounting seat 301. The limit seat 303 is connected to the blade 3. By connecting the limit seat 303 to the blade 3, the blade 3 can be preliminarily limited.

[0043] The blade 3 is installed on the lower mounting seat 301 through the limit seat 303, and the limit frame 305 is slidably connected to the inside of the upper mounting seat 302. The blade 3 is fixed by the cooperation of the limit seat 303 and the limit frame 305. The lower mounting seat 301 slides, so that the pushing block 304 and the limit seat 303 on the lower mounting seat 301 move accordingly. At this time, the limit seat 303 can drive the blade 3 to move, and the pushing block 304 contacts with the limit frame 305, so that the limit frame 305 moves. When the limit frame 305 coincides with the limit seat 303, the limit frame 305 is sleeved on the outer surface of the limit seat 303. At this time, under the action of the limit seat 303 and the limit frame 305, the limit seat 303 is further limited.

[0044] The outer surface of the upper mounting seat 302 is threadedly connected with a blocking ring 307, and the upper surface of the limit frame 305 is provided with a sliding seat 306, and the sliding seat 306 is slidably connected to the inner wall of the upper mounting seat 302, and the blocking ring 307 can limit the movement of the sliding seat 306, and then limit the movement of the limit frame 305, so that the limit frame 305 can fix the blade 3, and by moving the blocking ring 307 on the upper mounting seat 302, the blocking ring 307 can adjust whether to limit the sliding seat 306, and when the limit frame 305 moves, the sliding seat 306 moves accordingly and is located outside the upper mounting seat 302, and when the blocking ring 307 is on the outer surface of the upper mounting seat 302, the sliding seat 306 is blocked and cannot move, and then the limit frame 305 cannot move, thereby fixing the blade 3.

[0045] The outer surface of the lower mounting seat 301 is connected to a connecting rod 4, and the end of the connecting rod 4 is connected to a pulling block 401. The pulling block 401 is slidably connected to the outer surface of the handle 1, and the lower mounting seat 301 and the blade 3 can be driven to move through the connecting rod 4 and the pulling block 401. By pulling the pulling block 401, the pulling block 401 slides along the outer surface of the handle 1. Under the movement of the pulling block 401, the pulling block 401 drives the connecting rod 4 to move. At this time, the pulling block 401 pushes the lower mounting seat 301 to move. Under the movement of the lower mounting seat 301, the pushing block 304 pushes the limiting frame 305 to move, and at the same time, the blade 3 moves outward, so that the blade 3 can be inserted into the disinfection cover 2 to disinfect the blade 3.

[0046] The limiting assembly includes a moving seat 5, two tension springs 501 and a connecting seat 502. One end of the lower mounting seat 301 located inside the knife handle 1 is connected to the moving seat 5. The moving seat 5 is slidably connected inside the knife handle 1. When the moving seat 5 moves, the lower mounting seat 301 moves, driving the blade 3 to be fixed between the lower mounting seat 301 and the upper mounting seat 302.

[0047] The end of the movable seat 5 is connected to two tension springs 501, and the other ends of the two tension springs 501 are connected to the connecting seat 502. The connecting seat 502 is slidably connected to the inner wall of the handle 1, and the movable seat 5 moves to the end to limit the position of the blade 3. The sliding of the movable seat 5 is limited by the tension spring 501. When the pull block 401 and the connecting rod 4 are pushed to make the lower mounting seat 301 move outward for disinfection, the lower mounting seat 301 drives the movable seat 5 to move. Under the movement of the movable seat 5, the tension spring 501 is stretched. When the disinfection is completed, the connecting rod 4 and the pull block 401 are released, and the movable seat 5 returns to the starting position under the rebound of the tension spring 501, driving the blade 3 to be back between the lower mounting seat 301 and the upper mounting seat 302, and then the blade 3 can be stably fixed again by the shielding ring 307, which is convenient for the use of the blade 3 after disinfection.

[0048] The end of the connecting seat 502 is connected to an adjusting seat 503, and the adjusting seat 503 is slidably connected to the inner wall of the knife handle 1. The internal thread of the adjusting seat 503 is connected to a screw rod 504, and the screw rod 504 is rotatably connected to the inner wall of the knife handle 1. The end of the screw rod 504 outside the knife handle 1 is connected to a rotating handle 505. Under the action of the screw rod 504, the adjusting seat 503 moves. By rotating the rotating handle 505, the screw rod 504 can be driven to rotate. Under the rotation of the screw rod 504, the adjusting seat 503 moves along the outer surface of the screw rod 504, and then the connecting seat 502 moves, so that the connecting seat 502, the tension spring 501 and the moving seat 5 move accordingly, driving the lower mounting seat 301 to move, so as to move the blade 3 and make the blade 3 at a specified position.

[0049] The anti-mistouch component includes a gear 6, a block 601 and a rotating seat 602. The screw rod 504 is connected to the gear 6, and the gear 6 contacts the block 601. A toothing mechanism is provided on the gear 6, which contacts the block 601 through the toothing mechanism. The block 601 is connected to the rotating seat 602. The block 601 is rotatably connected to the outer surface of the handle 1 through the rotating seat 602. With the cooperation of the gear 6 and the block 601, the gear 6 can only rotate in one direction. When rotating in the opposite direction, the block 601 will prevent the gear 6 from rotating, so that in a natural state, the adjustment seat 503 cannot drive the connecting seat 502, the tension spring 501, the movable seat 5 and the lower mounting seat 301 to move outward, thereby further stabilizing the position of the blade 3.

[0050] The upper surface of the stopper 601 is connected with a return spring 603, and the other end of the return spring 603 is connected with a fixed seat 604, and the fixed seat 604 is connected with the handle 1. Under the action of the return spring 603, the stopper 601 is subjected to a pulling force. When the gear 6 pushes the stopper 601 to move, the return spring 603 rebounds and enables the stopper 601 to move in the opposite direction and contact the gear 6 again. The outer surface of the handle 1 is connected with a stopper rod 605, and the stopper rod 605 fits with the stopper 601. Under the action of the stopper rod 605, the position of the stopper 601 is limited. The outer surface of the handle 1 is sleeved with a rear cover 101, and the gear 6, the stopper 601 and the return spring 603 are supported by the rear cover 101. When the blade 3 is replaced, the stopper 601 is pulled so that the stopper 601 rotates under the action of the rotating seat 602, so that the reset spring 603 is stretched and the stopper 601 is separated from the gear 6. At this time, the rotating handle 505 and the screw rod 504 can be rotated in the opposite direction to move the lower mounting seat 301 outward. When the knife handle 1 is in use, the gear 6, the stopper 601 and the reset spring 603 are shielded by the rear cover 101 being sleeved on the outer surface of the knife handle 1, so that the knife handle 1 will not be inconvenient to use.

[0051] Working principle: when the knife handle 1 needs to be used, first remove the disinfection cover 2, place the blade 3 on the lower mounting seat 301, and connect the limiting seat 303 with the blade 3 to preliminarily limit the blade 3;

[0052] The handle 505 and the screw rod 504 are rotated, and the adjusting seat 503 moves along the outer surface of the screw rod 504 under the rotation of the screw rod 504, so that the connecting seat 502 moves, and the stopper 601 is subjected to a pulling force under the action of the return spring 603. When the gear 6 pushes the stopper 601 to move, the return spring 603 rebounds, so that the stopper 601 can move in the reverse direction and contact with the gear 6 again;

[0053] At this time, the connecting seat 502, the tension spring 501 and the moving seat 5 move accordingly, so that the lower mounting seat 301 moves inward, and the lower mounting seat 301 slides, so that the pushing block 304 and the limiting seat 303 on the lower mounting seat 301 move accordingly, and the limiting seat 303 can drive the blade 3 to move;

[0054] At the same time, the push block 304 contacts the limit frame 305, so that the limit frame 305 moves. When the limit frame 305 overlaps with the limit seat 303, the limit frame 305 is sleeved on the outer surface of the limit seat 303. At this time, under the action of the limit seat 303 and the limit frame 305, the limit seat 303 is further limited.

[0055] By rotating the shielding collar 307, the shielding collar 307 moves on the upper mounting seat 302, so that the shielding collar 307 can adjust whether to limit the sliding seat 306. When the limit frame 305 moves, the sliding seat 306 moves accordingly and is located outside the upper mounting seat 302. When the shielding collar 307 is on the outer surface of the upper mounting seat 302, the sliding seat 306 is blocked and cannot move, and the limit frame 305 cannot move, so that the blade 3 is fixed and can be used for normal surgery.

[0056] When the blade 3 needs to be disinfected during use, the shielding collar 307 is rotated so that the shielding collar 307 does not limit the sliding seat 306, and the pull block 401 and the connecting rod 4 are pushed to move the lower mounting seat 301 outward, so that the blade 3 is inserted into the disinfection cover 2 for disinfection;

[0057] At this time, the lower mounting seat 301 drives the movable seat 5 to move, and the movement of the movable seat 5 causes the tension spring 501 to be stretched. When the disinfection is completed, the connecting rod 4 and the pull block 401 are released, and the movable seat 5 returns to the starting position due to the rebound of the tension spring 501, driving the blade 3 to be back between the lower mounting seat 301 and the upper mounting seat 302, and then the blade 3 can be stably fixed again through the shielding ring 307, so as to facilitate the use of the blade 3 after disinfection.

[0058] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
