Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a safe and reliable disposable medical scalpel. Background Technology

[0002] In medical devices, the scalpel is an indispensable and important surgical tool in surgery. A scalpel is a special knife consisting of a blade and a handle, used to cut human or animal tissues. However, due to its simple structure, some unnecessary injuries can occur if care is not taken.

[0003] During surgery, doctors typically rely on nurses to pass disposable scalpels. If a patient requires urgent surgery, the doctor's movements while handling the scalpel may quicken, increasing the risk of hand injuries to both doctors and nurses. This raises safety concerns. Furthermore, disposable scalpels cannot be reused after use, which could lead to cross-infection. Since used scalpels are identical to unused ones, confusion can arise, potentially causing cross-infection among patients. Careless handling of used disposable scalpels can also injure staff. Therefore, a safe and reliable disposable medical scalpel solution is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a safe and reliable disposable medical scalpel, aiming to improve the problems of nurses potentially causing hand cuts to doctors or nurses when passing disposable scalpels due to the doctor's quick handling of the scalpel, the confusion caused by used and unused disposable scalpels leading to cross-infection of patients, and the potential for injury to staff when handling used disposable scalpels.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1-5 This utility model provides an embodiment of a safe and reliable disposable medical scalpel, including a handle 1, a blade shank 2 fixedly connected to the left side of the handle 1, a blade tip 3 fixedly connected to the left side of the blade shank 2, a shell 4 slidably connected to the outer periphery of the blade shank 2, a locking block 5 fixedly connected to the top of the shell 4, multiple locking slots 6 provided on the top of the blade shank 2, the locking block 5 located in the middle of the locking slots 6, a locking block 7 fixedly connected to the bottom of the blade shank 2, and locking slots 8 and sliding grooves 9 arranged sequentially from left to right on the bottom of the shell 4. The locking block 7 slidably connects to the middle of the locking slots 8 or sliding grooves 9. The shell 4 ensures that the disposable scalpel will not cause injury to the hands of doctors or nurses when being passed. By pushing the shell 4, the locking blocks at the top are engaged. The first 5 disengages from the middle slot 6, allowing the outer shell 4 to move. When the outer shell 4 moves to the right slot 6, the first 5 secures it, allowing the blade tip 3 to protrude for use. After use, pushing the outer shell 4 disengages the first 5 from the right slot 6. When the outer shell 4 moves to the left slot 6, the first 5 secures it, and the second 7 enters the slot 8 to secure the entire outer shell 4. This prevents the blade tip 3 of the disposable scalpel from being exposed after use, avoiding the inability to distinguish the condition of the disposable scalpel and thus preventing cross-infection of patients caused by using a used disposable scalpel. It also prevents injury to staff when handling used disposable scalpels.

[0029] Limiting blocks 10 are fixedly connected to both sides of the inner side of the outer shell 4. A limiting groove 11 is provided on the outer periphery of the tool holder 2. The limiting blocks 10 are slidably connected to the middle of the limiting groove 11. The limiting groove 11 limits the outer shell 4 to prevent the outer shell 4 from shifting or tilting, which would make it impossible to effectively fix the outer shell 4.

[0030] The front of the handle 1 is equipped with scale lines, which can be conveniently measured using a disposable scalpel when it is necessary to measure the incision size during surgery.

[0031] The front of the handle 2 is provided with a guide mark, which makes it easy to know the switching direction when using the disposable scalpel.

[0032] There are three slots 1 and 6. The middle slot 1 and 6 can cover the blade tip 3 with the outer shell 4, while the right slot 1 and 6 can expose the blade tip 3 for easy use. When the outer shell 4 moves to the left slot 1 and 6, the second block 2 and 7 can enter the interior of the second slot 2 and 8 to double fix the disposable scalpel after use and prevent it from being reused.

[0033] The outer shell 4 is sized to match the blade tip 3.

[0034] The top of the outer casing 4 is provided with anti-slip texture, which makes pushing the outer casing 4 more stable and convenient.

[0035] Working principle: When a disposable scalpel is needed, the outer casing 4 prevents injury to the hands of doctors or nurses during the transfer of the scalpel. By pushing the outer casing 4, the top latch 5 disengages from the middle slot 6, allowing the outer casing 4 to move. When the outer casing 4 moves to the right slot 6, the latch 5 secures it, allowing the blade tip 3 to protrude for use. After use, by pushing the outer casing 4, the latch 5 disengages from the right slot 6, and when the outer casing 4 moves to the left slot 6, the latch 5 secures it. Then, the second latch 7 enters the slot 8, securing the entire outer casing 4. This prevents the blade tip 3 of the used disposable scalpel from being exposed, avoiding the inability to distinguish the use of the scalpel and thus preventing cross-infection of patients from using used disposable scalpels. It also prevents injury to staff when handling used disposable scalpels.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
