Description

Technical Field

[0001] This utility model relates to the field of surgical technology, specifically to an external puncture surgical knife. Background Technology

[0002] External puncture scalpels are minimally invasive surgical instruments widely used in various clinical departments. Their main uses include establishing surgical access, tissue puncture biopsy, and therapeutic procedures. Common types of external puncture scalpels include laparoscopic trocars, ophthalmic puncture scalpels, and general-purpose puncture scalpels. The shape and usage of puncture scalpels vary depending on the medical category.

[0003] For example, patent CN215606823U discloses a puncture knife. It includes a handle and a blade. The handle comprises a cylindrical main body and a tapered grip connected to one end of the main body. The main body and grip are integrally formed. A notch is provided at the end of the main body away from the grip to prevent the puncture knife from rolling during surgery or getting stuck in packaging. The blade includes a connecting part and a blade head. The connecting part is connected to the end of the grip away from the main body, and the centerline of the connecting part coincides with the centerline of the handle. The blade head includes a blade body with opposing first and second sides. The first and second sides extend along the longitudinal center plane of the blade body at the bottom and intersect to form a cutting edge. The cutting edge forms an angle of 30 to 45 degrees with the front side of the blade body. This knife can both cut and dissect scleral flaps, making it convenient and efficient to use during surgery.

[0004] During the use of the aforementioned ophthalmic surgical scalpel, the handle is a long rod. This design makes it easy for the glove to slip after coming into contact with liquid when the surgeon is wearing gloves and holding the scalpel handle, thus affecting the stability of the surgeon's hand operation.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide an external puncture scalpel that solves the problem that, due to the long rod-shaped handle, when the surgeon is wearing gloves and holding the scalpel handle for surgery, the glove position is prone to slipping from the handle position after contact with liquid, thereby affecting the stability of the surgeon's hand operation.

[0007] The technical solution adopted by this application to solve its technical problem is: an external puncture scalpel, including a handle and a blade body installed at one end of the handle, wherein a gripping component for improving the friction of the handle is fixedly installed on the upper end of the outer surface of the handle, and a limiting component for limiting the thumb of the hand is bound to one end of the gripping component.

[0008] Furthermore, the outer wall of the handle is provided with concave grooves on both sides of one end, and the inner wall of the concave groove is provided with slots on both the upper and lower ends.

[0009] Furthermore, the gripping component includes an embedded card block and semi-circular card balls respectively fixedly installed on the upper and lower ends of the embedded card block.

[0010] Furthermore, an outer plate is fixedly installed on one end of the outer wall of the embedded card block, and an anti-slip adhesive layer is embedded in the outer wall of the outer plate. An extension block is fixedly installed in the middle of one end of the outer plate, and a through groove is opened in the middle of one end of the extension block.

[0011] Furthermore, the limiting component includes a soft adhesive tape and a pull block fixedly installed at one end of the soft adhesive tape.

[0012] Furthermore, a magnetic sticker A is provided on the upper side of one end of the soft tape, and a set of magnetic stickers B is provided on one side of the magnetic sticker A.

[0013] The beneficial effects of this application are as follows: The external puncture scalpel provided by this application allows the doctor to hold the scalpel by gripping the anti-slip rubber layer, thereby increasing the friction between the anti-slip rubber layer and the doctor's glove. At the same time, when the doctor's thumb is placed on the upper end of the anti-slip rubber layer, a soft tape can be placed over the upper end of the doctor's thumb, with one end of the soft tape passing through the inner cavity of the through groove. This allows magnetic stickers A and B to be magnetically connected, thereby limiting and fixing the doctor's thumb to one end of the external plate through the soft tape, improving the stability of the doctor's grip on the scalpel handle.

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0018] like Figure 1 As shown, an external puncture scalpel includes a handle 1 and a blade 2 installed at one end of the handle 1. A gripping component 3 for improving the friction of the handle 1 is fixedly installed on the upper end of the outer surface of the handle 1. A limiting component 4 for limiting the thumb of the hand is bound to one end of the gripping component 3.

[0019] like Figures 2-3 As shown, an outer plate 33 is fixedly installed on one end of the outer wall of the embedded card block 31. An anti-slip rubber layer 34 is embedded in the outer wall of the outer plate 33. The anti-slip rubber layer 34 is designed to directly contact the doctor's hand to increase friction. An extension block 35 is fixedly installed in the middle of one end of the outer plate 33. A through groove 36 is provided in the middle of one end of the extension block 35. The through groove 36 is designed to be used in conjunction with the limiting component 4.

[0020] like Figure 4 As shown, the limiting component 4 includes a soft tape 41 and a pull block 42 fixedly installed at one end of the soft tape 41.

[0021] A magnetic sticker A43 is provided on the upper side of one end of the soft tape 41, and a set of magnetic stickers B44 is provided on one side of the magnetic sticker A43. The magnetic stickers A43 and B44 are magnetically connected, and one end of the soft tape 41 is movably inserted into the inner cavity of the through groove 36.

[0022] In this application, when a doctor holds a scalpel, the friction between the anti-slip layer 34 and the doctor's glove is increased by holding the anti-slip layer 34 on the hand. At the same time, when the doctor's thumb is placed on the upper end of the anti-slip layer 34, a soft tape 41 can be placed over the upper end of the doctor's thumb, with one end of the soft tape 41 passing through the inner cavity of the through groove 36, so that the magnetic stickers A43 and B44 are magnetically connected. Thus, the soft tape 41 limits and fixes the doctor's thumb to one end of the outer plate 33, improving the stability of the doctor's grip on the scalpel handle 1.

[0023] like Figure 2 As shown, concave grooves 11 are respectively provided on both sides of one end of the outer wall of the handle 1, and slots 12 are respectively provided on both the upper and lower ends of the inner wall of the concave groove 11.

[0024] like Figure 3 As shown, the gripping component 3 includes an embedded card block 31 and semi-circular locking balls 32 respectively fixedly installed on the upper and lower ends of the embedded card block 31. The embedded card block 31 is movably installed in the inner cavity of the concave groove 11 and is locked in the inner cavity of the card slot 12 by the semi-circular locking balls 32.

[0025] In this application, when the anti-slip rubber layer 34 wears out, or when it is necessary to disinfect the scalpel handle, the extension block 35 can be pulled to move one end of the outer plate 33 and the embedded locking block 31, thereby causing the semi-circular locking balls 32 on both sides of one end of the embedded locking block 31 to be ejected from the inner cavity of the locking groove 12. At the same time, the semi-circular locking balls 32 on both sides of the other end of the embedded locking block 31 will exit from the locking groove 12 in the same way, thus completing the disassembly of the embedded locking block 31 from the inner cavity of the concave groove 11, which facilitates the disinfection of the scalpel and allows the damaged anti-slip rubber layer 34 to be replaced.

[0026] In summary: By using the anti-slip rubber layer 34, soft tape 41, through groove 36, magnetic sticker A43, and magnetic sticker B44 in combination, the soft tape 41 can fix the doctor's thumb to one end of the outer plate 33, improving the stability of the doctor's grip on the scalpel handle 1. By using the anti-slip rubber layer 34, extension block 35, outer plate 33, embedded locking block 31, semi-circular locking ball 32, locking groove 12, and concave groove 11 in combination, the embedded locking block 31 can be removed from the inner cavity of the concave groove 11, which facilitates the sterilization of the scalpel. At the same time, damaged anti-slip rubber layer 34 can be replaced. All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description in the instruction manual and the attached drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding, which are mature technologies in the existing technology. The machinery, parts, and equipment all adopt conventional models in the existing technology, and the circuit connection adopts conventional connection methods in the existing technology, which will not be described in detail here.
