Description

Technical Field

[0001] This utility model relates to the field of surgical knife manufacturing technology, specifically a surgical knife with an antibacterial coating. Background Technology

[0002] The scalpel is the most powerful tool that surgeons use to perform surgery. With the progress and development of social science and technology, the scalpel itself has evolved from the original stone, wood, copper and iron products into multi-purpose modern high-tech products that integrate functions such as cutting, hemostasis, aspiration and even radiotherapy, such as electrocautery scalpels, argon plasma coagulation scalpels, and ultrasonic scalpels.

[0003] A search revealed Chinese patent application CN 117821704 A, which discloses a method for preparing an antibacterial surgical scalpel with a nano-titanium nitride coating. The method includes the following steps: S1. Stainless steel is selected as the scalpel substrate material. A suitable size is obtained through mechanical cutting. Antibacterial metal elements are added to the scalpel substrate, followed by solution treatment to obtain an antibacterial substrate. The specific steps for adding the metal elements are: S1.1. Metal powder is added to the surface of the scalpel substrate, then smelted in a vacuum furnace, cast into an ingot, and then the surface of the ingot is peeled off and forged into a 25*160*180mm forging blank. This invention sequentially performs antibacterial treatment on the scalpel substrate material, applies a nano-titanium nitride coating to the scalpel substrate using cold spraying technology, and performs vacuum heat treatment and surface nano-sizing treatment. This allows for the acquisition of a scalpel coating with hydrophilic angle, hardness, hemolysis rate, and tissue adhesion that meet the requirements for use. Furthermore, surface nano-sizing treatment helps reduce the amount of tissue adhesion in the scalpel coating.

[0004] However, since most scalpels are polished to a very smooth surface after manufacturing, and most scalpels lack a handle, they are inconvenient to use and require doctors to spend a long time getting used to them. At the same time, most scalpels do not allow adjustment of the grip distance from the blade, which also makes them inconvenient for doctors to use. In view of this, we propose a scalpel with an antibacterial coating. Utility Model Content

[0005] The purpose of this invention is to provide a scalpel with an antibacterial coating, which solves the problem that most scalpels lack a handle, making the smooth-surfaced scalpel easy to fall during use.

[0023] 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. Example

[0024] Please see Figure 1 - Figure 4This utility model provides a scalpel with an antibacterial coating, including an antibacterial scalpel body 1. The outer surface of the antibacterial scalpel body 1 is coated with a nano-titanium nitride coating. The nano-titanium nitride coating gives the entire scalpel body high hardness, high strength, high wear resistance, antibacterial properties, and rust resistance. The left surface of the antibacterial scalpel body 1 is provided with an anti-dislodgement mechanism 2. The anti-dislodgement mechanism 2 includes a connecting steel rod 21. The left surface of the connecting steel rod 21 has a cross-shaped groove 22. The inner surface of the cross-shaped groove 22 is slidably connected to a movable steel rod 23. By providing the cross-shaped groove 22 on the left surface of the connecting steel rod 21, the movable steel rod 23 can limit the connecting steel rod 21, so that the connecting steel rod 21 can only slide within the movable steel rod 23. The front surface of the scalpel 23 has a linear array of circular holes 24. A disposable scalpel handle body 25 is slidably connected to the inner surface of the circular holes 24. A plastic rod is fixed to the rear surface of the disposable scalpel handle body 25. The plastic rod is inserted into the circular holes 24, and friction limits the disposable scalpel handle body 25. An elastic movable buckle 26 passes through the upper surface of the movable steel rod 23 and is slidably connected to it. The plastic rod has a groove through which the elastic movable buckle 26 can be inserted, limiting the disposable scalpel handle body 25 and making it more stable. The antibacterial scalpel body 1 will not shake during use. The lower surface of the elastic movable buckle 26 passes through the disposable scalpel handle body 25 and is slidably connected to it. The sliding connection, the elastic movable buckle 26 is composed of a movable buckle and a spring. The movable buckle is U-shaped and can limit the disposable knife handle body 25, making the disposable knife handle body 25 more stable. The left surface of the movable steel rod 23 has a lead screw 27 passing through it and is rotatably connected to the lead screw 27. The lead screw 27 passes through the connecting steel rod 21 and is threadedly connected to the connecting steel rod 21. The upper surface of the elastic movable buckle 26 has a sliding groove 28. The inner surface of the sliding groove 28 has an elastic block 29 slidably connected. The elastic block 29 is composed of a connecting rod, a spring and a trapezoidal block. The connecting rod and the sliding groove 28 simultaneously limit the trapezoidal block, so that the trapezoidal block can only slide within the sliding groove 28. At the same time, when the trapezoidal block is squeezed, it will compress the spring. The sliding groove 28 can limit the elastic block. 29 is limited so that the elastic block 29 can only slide within the slide groove 28. The cross-sectional shape of the elastic block 29 is trapezoidal. By setting the cross-sectional shape of the elastic block 29 to be trapezoidal, it is easier to release the disposable knife handle body 25. An F-type locking rod 210 is fixedly connected to the upper surface of the movable steel rod 23. The inner surface of the F-type locking rod 210 is slidably connected to the elastic block 29. The cooperation between the F-type locking rod 210 and the elastic block 29 makes the elastic movable buckle 26 more stable. The disposable knife handle body 25 is provided in two sets and is symmetrically arranged with the center line of the antibacterial surgical knife body 1 as the axis of symmetry. Both sets of disposable knife handle bodies 25 are made of plastic. The lower surface of the disposable knife handle body 25 has grooves 211 arranged in a circumferential array.By creating a groove 211 on the disposable scalpel handle body 25, the surgeon can easily grip the scalpel, and it is also easy to disassemble after surgery. A protective mechanism 3 is provided on the front surface of the disposable scalpel handle body 25. The protective mechanism 3 includes an L-shaped protective plate 31. A limiting groove 32 is created on the front surface of the disposable scalpel handle body 25. The L-shaped protective plate 31 is slidably connected to the inner surface of the limiting groove 32. The limiting groove 32 limits the L-shaped protective plate 31, ensuring that it can only slide within the limiting groove 32, thus improving stability. Two sets of L-shaped protective plates 31 are provided, symmetrically arranged with the center line of the antibacterial scalpel body 1 as the axis of symmetry. A pin 33 passes through the inner surface of the limiting groove 32 and is slidably connected to it. The pin 33 passes through the L-shaped protective plate 31 and is slidably connected to it.

[0025] In this embodiment, the flexible movable buckle 26, the elastic block 29, the F-shaped locking rod 210, and the disposable knife handle body 25 facilitate the installation and disassembly of the disposable knife handle body 25. At the same time, the screw rod 27, the L-shaped protective plate 31, and the pin 33 control the distance between the scalpel and the handle, ensuring that the sharp edge of the scalpel will not cut objects or people.

[0026] Working principle: During surgery, after the doctor pulls the pin 33 out of the L-shaped protective plate 31, the L-shaped protective plate 31 can be pulled out from the limiting groove 32, exposing the antibacterial scalpel body 1, allowing the doctor to perform the surgery. During the surgery, when it is necessary to insert it into the patient's body, the antibacterial scalpel body 1 can be extended into the patient's body by rotating the screw 27 clockwise. Simultaneously, rotating it counterclockwise allows the antibacterial scalpel body 1 to retract towards the movable steel rod 23. After the surgery, by pressing the elastic movable buckle 26 and moving it downwards, the elastic movable buckle 26... When moving downwards, the spring is compressed, which in turn moves the elastic block 29 downwards. After moving downwards, the inclined surface of the elastic block 29 is squeezed by the F-type locking rod 210 and retracts into the slide groove 28. After releasing the elastic movable buckle 26, the elastic movable buckle 26 moves upwards by the elastic force of the spring. Before the elastic block 29 has passed the spring's return position, the elastic movable buckle 26 moves upwards, causing the elastic block 29 to disengage from the F-type locking rod 210. At the same time, after the elastic movable buckle 26 disengages from the groove of the plastic rod of the disposable knife handle body 25, the disposable knife handle body 25 can be removed and replaced.
