Description

Technical Field

[0001] The present invention relates to a device for removing a surgical knife blade from a knife handle. Background Art

[0002] like Figure 1 , Figure 2 , Figure 3 As shown, a conventional surgical knife generally comprises a reusable, sterilizable, elongated handle 12, on which a replaceable blade 10 having a longitudinal groove 11 can be fixed. At the distal end of the handle 12 is a shank 13, on the side wall of which a slide groove is engraved. During assembly, the shank is inserted into the groove of the blade, and the narrowed part of the groove is inserted into the slide groove on the side wall of the shank, so that the assembly is stable.

[0003] The handle 12 is used repeatedly, but the blade 10 is usually discarded after one use, either because the blade 10 becomes dull or contaminated, or because another style of blade 10 is needed. In order to remove the blade 10 from the handle 12, the rear portion of the tang 13 without the slide groove must first be withdrawn from the groove 11, and then the portion with the slide groove is gradually removed.

[0004] Manual removal of the blade 10 is very dangerous. During operation, the operator is in danger of being cut by the sharp blade 10. With the ever-increasing spread of blood-borne diseases such as AIDS and hepatitis, any accidental injury caused by the blade 10 may lead to infection or contamination. Summary of the invention

[0005] In view of this, the present invention provides a surgical knife blade remover, which can conveniently and quickly remove the blade from the handle.

[0006] In order to solve the above technical problems, the technical solution of the present invention is to use a surgical knife blade remover, including a remover body, the remover body is provided with a blade groove for inserting the blade and a shank groove for inserting the shank of the handle; the blade groove and the shank groove cross each other in cross-section. The principle of the present invention is to clamp the blade through the blade groove, and then flip the handle downward to disengage the shank from the groove on the blade, thereby achieving the purpose of removing the blade.

[0007] As an improvement, the bottom of the blade groove is provided with insert plates on the left and right sides of the shank groove, and the insert plates can slide forward and backward along the blade groove; a flap is provided at the bottom of the shank groove, and the distal end of the flap is movably connected to the disassembler body; and when the flap is flipped, the insert plate can be driven to slide. When the handle is flipped, although the shank will be separated from the groove most of the time, it is not ruled out that the shank and the groove are too firmly matched, and the entire blade is pulled out of the blade groove when the handle is flipped, causing the disassembly to fail. A flap is provided at the bottom of the shank groove. When the handle is flipped downward, the flap flips downward with the handle. First, it can provide space for the handle to flip downward so that it can smoothly disengage from the groove on the blade. Second, when the flap is flipped, it can drive the insert plate to slide forward, so that the insert plate is inserted between the blade and the handle, and at the same time blocks and supports the blade, so that the handle can be completely separated from the blade groove when it is flipped downward to avoid pulling the blade out of the blade groove.

[0008] As a further improvement, a slide groove is provided at the rear of the plug plate, a slider is provided in the slide groove, the plug plate is connected to the slider, a tooth is provided at the bottom of the slider, and a gear meshing with the teeth at the bottom of the slider is also provided, and the distal end of the flap is fixed to the gear. The flipping of the flap drives the gear to rotate, and the rotation of the gear drives the slider to slide so that the plug plate extends.

[0009] As another further improvement, a return spring is arranged between the slide block and the end wall of the slide slot, so that the plug plate and the flap are automatically returned to their original positions after the force is released.

[0010] As an improvement, the upper part of the tang groove intersects with the middle part of the blade groove, providing sufficient space for the handle to be turned.

[0011] As an improvement, the blade slot has a height of 0.5-0.8 mm and a width of 8-10 mm, and the shank slot has a height of 3-4 mm and a width of 1.5-2.5 mm, so that the remover can adapt to more blade handles without being too loose to be fixed.

[0012] The invention is beneficial in that: the surgical blade remover with the above structure utilizes the blade groove to clamp the blade and then flips the handle to achieve the purpose of removing the blade. The removal method is convenient and quick, and the removal mechanism is simple and easy to use. When using, there is no need to hold the blade to avoid being cut, eliminating the hidden danger of infection for medical staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 4-Figure 6 As shown, the present invention includes a disassembler body 1, on which a blade slot 2 for inserting a blade 10 and a shank slot 3 for inserting a shank 13 of a handle 12 are formed; the blade slot 2 and the shank slot 3 are cross-shaped in cross section. Preferably, the upper part of the shank slot 3 intersects with the middle part of the blade slot 2. The bottom of the blade slot 2 is provided with plug plates 4 on the left and right sides of the shank slot 3, and the plug plates 4 can slide forward and backward along the blade slot 2; a flap 5 is provided at the bottom of the shank slot 3, and the far end of the flap 5 is movably connected to the disassembler body 1; and when the flap 5 is flipped, the plug plate 4 can be driven to slide. A slide groove is provided behind the plug plate 4, and a slider 7 is provided in the slide groove, and the plug plate 4 is connected to the slider 7; the bottom of the slider 7 is provided with teeth; and a gear 6 meshing with the teeth at the bottom of the slider 7 is also provided, and the far end of the flap 5 is fixed to the gear 6. A reset spring 8 is provided between the slider 7 and the end wall of the slide groove.

[0022] The blade groove 2 has a height of 0.5-0.8 mm and a width of 8-10 mm; the shank groove 3 has a height of 3-4 mm and a width of 1.5-2.5 mm.

[0023] When in use, insert the blade 10 into the blade slot 2 so that the entire blade 10 is just immersed in the blade slot 2. Pull the handle 12 downward so that the flap 5 also flips down with the handle 12. At this time, due to the clamping of the blade slot 2, the blade 10 remains motionless, and the part of the rear of the shank 13 that is not engraved with a sliding groove is separated from the groove of the blade 10. At the same time, the flipping of the flap 5 drives the gear 6 to rotate, and the rotation of the gear 6 drives the slider 7 to move so that the insert plate 4 fixed to the slider 7 extends out of the blade slot 2 and is inserted between the blade 10 and the handle 11. Continue to flip the handle 12. Due to the support of the insert plate 4, the blade 10 is prevented from moving with the handle 12, forcing the two to separate. After the handle 12 is removed, the slider 7 is reset to the bottom under the action of the reset spring 8, and the insert plate 4 and flap 5 are also reset accordingly. At this time, the blade 10 located in the blade slot 2 can be poured out.

[0024] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention, and the protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
