Description

Technical Field

[0001] The utility model particularly relates to an anti-drop handle structure for an orthopedic drill bit. Background Art

[0002] Orthopedic drill bits are medical devices used in orthopedic surgery, specially designed for drilling holes in bones. Such drill bits are usually made of high-hardness materials to ensure effective drilling in hard bones. Currently, the types of orthopedic drill bits include hollow drill bits, solid drill bits, locking drill bits, etc. They are characterized by high precision, high wear resistance and reusability. Orthopedic drill bits need to be disinfected before use to prevent infection.

[0003] Usually, orthopedic drills are usually used with electric instruments or manpower during surgery, and the end of a hand drill is usually equipped with a handle for easy grasping. This type of drill is usually made of metal as a whole and equipped with a T-shaped handle. The handle is grasped and rotated to achieve the purpose of drilling or auxiliary drilling. However, in actual operation, due to the complex surgical environment, the hands are often contaminated with liquids, making it difficult to hold the handle steadily, and there is even a risk of slipping out of the hand, which in turn causes the drill to deviate and affects the surgical effect.

[0004] Therefore, it is necessary to invent an orthopedic drill bit anti-drop handle structure to solve the above problems. Utility Model Content

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] The utility model provides Figure 1-5 The orthopedic drill bit anti-drop handle structure shown includes a handle portion 2 provided at the rear end of the drill head portion 1. The handle portion 2 includes a connecting rod 21 and a grip 22. The grip 22 is vertically fixed to the end of the connecting rod 21.

[0031] Specifically, a mounting plate 23 extends from the bottom of the handle 22, and a receiving plate 24 is provided at both ends. The mounting plate 23 and the receiving plate 24 are both provided with a plurality of slots 25, and the anti-slip components 3 are installed in the slots 25;

[0032] In this embodiment, the handle portion 2 includes a connecting rod 21 and a grip 22. The grip 22 is vertically fixed to the end of the connecting rod 21, ensuring a natural and comfortable hand posture during operation and convenient operation. A mounting plate 23 extends from the bottom of the grip 22, and a storage plate 24 is provided at both ends of the mounting plate. Both the mounting plate 23 and the storage plate 24 have multiple slots 25 for mounting the anti-slip assembly 3.

[0033] Reference Figure 2-5 The anti-slip component 3 includes two groups of card blocks 31 and an elastic band 32. The elastic band 32 connects the two groups of card blocks 31. The two groups of card blocks 31 are correspondingly fixed in the card slots 25, and limiting components 33 are also installed on both sides of the card blocks 31. The limiting components 33 limit the card blocks 31 in the card slots 25.

[0034] In this embodiment, the anti-slip assembly 3 consists of two sets of clamping blocks 31 and an elastic band 32. The elastic band 32 connects the two sets of clamping blocks 31 and secures them within the clamping slot 25 to ensure that the operator's hand is firmly attached to the handle. To further prevent the clamping blocks 31 from loosening, limiter assemblies 33 are installed on both sides of the clamping blocks. The limiter assemblies 33 prevent the clamping blocks from falling out of the clamping slot during use through the cooperation of limiter slots 334 and limiter plates 332.

[0035] Specifically, the limiting assembly 33 includes a fixed shaft 331 installed on both sides of the blocking block 31, a limiting plate 332 is installed on the fixed shaft 331, and blocks 333 are also provided on both sides of the fixed shaft 331. Limiting grooves 334 are provided on the block blocks 333 on both sides, and the limiting grooves 334 correspond to the limiting plates 332, and the block blocks 333 on both sides respectively limit the rotation of the limiting plates 332 on both sides.

[0036] In this embodiment, the limiting assembly 33 includes fixed shafts 331 mounted on either side of the clamping block 31. Fixed shafts 331 are mounted with limiting plates 332 to constrain the clamping block. Stoppers 333 are positioned on either side of the fixed shaft and feature limiting slots 334 that engage with the limiting plates 332 to ensure they retain the clamping block during rotation. When the limiting plates 332 are rotated to a horizontal position, their length at least exceeds the minimum width of the clamping slot 25, ensuring the block's stability within the slot.

[0037] Specifically, the stopper 333 is L-shaped as a whole, and the stoppers 333 on both sides are centrally symmetrical about the fixed axis 331 , and the width of the limiting groove 334 corresponds to the thickness of the limiting plate 332 .

[0038] Specifically, the limit assembly 33 is arranged on both sides of the block 31 and corresponds to the position where the width of the slot 25 is smaller. When the limit plate 332 rotates to a horizontal state, its length is at least greater than the minimum width of the slot 25. The length of the slot 25 corresponds to the length of the block 31.

[0039] Specifically, the card slot 25 is a T-shaped card slot, the card block 31 is correspondingly a T-shaped card block, and a mounting slot 311 is provided at the bottom of the card block 31 . Fixing holes 321 are provided at both ends of the elastic band 32 and are fixed in the mounting slot 311 .

[0040] In this embodiment, the slot 25 is designed as a T-shaped structure, and the block 31 is also a T-shaped block with a mounting slot 311 at the bottom. The elastic band 32 is fixed in the mounting slot 311 through fixing holes 321 at both ends, further ensuring the stability of the block 31.

[0041] Specifically, the connecting rod 21 is fixed at the middle position of the bottom of the handle 22 , and anti-slip grooves 26 are provided on both sides of the connecting rod 21 on the handle 22 .

[0042] Specifically, the slots 25 on the receiving plates 24 at both ends of the handle 22 are vertically arranged, and the slots 25 on the bottom mounting plate 23 are evenly spaced and horizontally arranged.

[0043] In this embodiment, the connecting rod 21 is fixed at the middle position of the bottom of the handle 22. The handle 22 is also designed with anti-slip grooves 26 to increase stability when holding and prevent hand slippage. At the same time, the slots 25 on the storage plate 24 are vertically arranged, and the slots on the mounting plate 23 are evenly distributed horizontally, optimizing space utilization and functional configuration.

[0044] In this embodiment, during actual operation, the operator will distribute his fingers on both sides of the handle 22 and use the gaps between the fingers to clamp the connection between the handle 22 and the connecting rod 21. At this time, the anti-slip component 3 is installed between the fingers on both sides, and the finger parts are fixed, so that the operator will not slide during use, thereby improving the stability of use. When not in use, the anti-slip component 3 can be placed on the storage plates 24 on both sides of the handle 22, so that it can act as a hanging rope, thereby enhancing the practicality of the device. In addition, since the structure of the handle is relatively simple, the design of the T-shaped slot and the card block facilitates quick disassembly and cleaning after surgery, effectively preventing the residue of bacteria and contaminants.

[0045] It is worth mentioning that the reasonable distribution of the card slots 25 and the flexible design of the anti-drop assembly 3 enable the handle to meet the needs of operators with different finger sizes, thereby improving the user experience of different operators.

[0046] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
