Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a non-standard bone cutting tool. Background Technology

[0002] For medical devices, bone processing equipment is generally a bone saw. Unlike food-grade bone saws, medical bone saws are made entirely of stainless steel and are designed for mass production of bone blocks. However, both types of saws are only for rough processing, producing bone blocks in segments of square or sheet-like shape with a precision of 0.5-1mm. The current demand is for processing irregularly shaped bone blocks, prioritizing both shape and precision. The shortcomings and deficiencies of existing technologies are as follows:

[0003] 1. Bone saws can only perform rough processing and cannot precisely control the size and shape of bone blocks, such as wedges or triangles;

[0004] 2. During the fine processing of bone blocks, the small size of the blocks poses a risk of hand cuts for the operators.

[0005] To address the aforementioned problems, this utility model provides a non-standard bone cutting tool. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a non-standard bone cutting tool, which solves the problems mentioned in the background.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a non-standard bone cutting tool, including a base, a straightedge is vertically arranged on one side of the base, and multiple bone block grooves for placing bone blocks are opened on the other side of the base.

[0008] The upper surface of the base has pressure plates pressed into the grooves of multiple bone blocks. Multiple limiting pressure strips are evenly distributed in the middle of the upper surface of the base above one side of the pressure plate. The multiple limiting pressure strips form a slot between the upper surface of the base to facilitate the insertion of the pressure plates.

[0009] As a further technical solution of this utility model, when one side of the pressure plate is inserted into the slot, the other side of the pressure plate is pressed against the top of the bone block groove.

[0010] As a further technical solution of this utility model, a handle is vertically provided in the middle of the upper surface of the pressure plate, and the limiting pressure strip is made of plastic.

[0011] As a further technical solution of this utility model, a handle is provided at one end of the base near the limiting pressure strip, and a handle is provided at the corner of the other end of the base. Both handles are integrally formed with the base.

[0012] As a further technical solution of this utility model, the outer surface of the ruler is a smooth plane, and the ruler and the limiting strip are integrally formed with the base.

[0013] This utility model provides a non-standard bone cutting tool, which has the following advantages compared with the prior art:

[0014] This design presents a non-standard bone cutting fixture, in which the base, straightedge, and limiting pressure strip are all integrated. A pressure plate is inserted into a slot below the limiting pressure strip, and the limiting pressure strip presses against the pressure plate, facilitating the pressure plate's clamping and positioning of the bone block within the bone block's groove. This ensures the stability of the bone block during cutting and eliminates the need for manual support of the bone block, reducing the risk of operator hand injury. Furthermore, it is equipped with two handles, allowing the operator's hands to remain away from the saw blade throughout the entire process, further reducing operational risks. The overall operation is convenient, and the fixing and removal of bone blocks are also easier. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5This utility model provides a technical solution for a non-standard bone cutting tool: a non-standard bone cutting tool includes a base 1, a straightedge 2 is vertically arranged on one side of the base 1, the outer surface of the straightedge 2 is a smooth plane, and the straightedge 2 and the limiting pressure strip 3 are integrally formed with the base 1. A handle 4 is provided on one end of the base 1 near the limiting pressure strip 3, and a handle 7 is provided at the corner of the other end of the base 1. Both handle 4 and handle 7 are integrally formed with the base 1. The straightedge 2 is designed to fit tightly against the baffle of the bone saw, ensuring that the entire base 1 moves in a straight line along the baffle of the bone saw when dragged. This makes it easier for the vertical band saw of the bone saw to cut the square bone block in the bone block groove 5 along one side of the base 1.

[0023] like Figure 4 and 5 On the other side of the base 1, there are multiple bone block grooves 5 for placing bone blocks. The inner diameter of the bone block grooves 5 is different. According to the processing requirements, the bone block can be placed in the corresponding size bone block groove 5. Moreover, the height of the bone block groove 5 is lower than the actual height of the bone block. When it is necessary to process the square bone block into a wedge or triangle, the square bone block can be placed in the bone block groove 5, and the excess part outside the bone block groove 5 can be sawed off using a bone sawing machine.

[0024] A pressure plate 6 is pressed onto the upper surface of the base 1 at multiple bone block grooves 5. Multiple limiting pressure strips 3 are evenly distributed above one side of the pressure plate 6 in the middle of the upper surface of the base 1. The multiple limiting pressure strips 3 form a slot between the upper surface of the base 1 and the base 1 to facilitate the insertion of the pressure plate 6. When one side of the pressure plate 6 is inserted into the slot, the other side of the pressure plate 6 is pressed against the top of the bone block groove 5. A handle is vertically set in the middle of the upper surface of the pressure plate 6. The limiting pressure strips 3 are made of plastic. After the square bone block is placed into the bone block groove 5, one end of the pressure plate 6 is inserted into the slot. The multiple limiting pressure strips 3 are used to press the pressure plate 6 to ensure that the pressure plate 6 is pressed against the upper surface of the bone block groove 5, thereby achieving the pressing and positioning of the square bone block and ensuring its stability during cutting and processing.

[0025] The working principle of this utility model is as follows: the square bone block is placed into the corresponding bone block groove 5 according to the corresponding size. The height of the bone block groove 5 is lower than the actual height of the bone block. Then, one end of the pressure plate 6 is inserted into the slot. Multiple limiting pressure strips 3 are used to squeeze the pressure plate 6 to ensure that the pressure plate 6 is pressed on the upper surface of the bone block groove 5, thereby achieving the pressing and positioning of the square bone block.

[0026] After the square bone block is fixed, move the base 1 under the bone saw, so that the ruler 2 is close to the baffle of the bone saw. Then adjust the distance to align the saw blade of the bone saw with the position of the square bone block.

[0027] Then push the handle 27 to make the straightedge 2 move in a straight line along the bone saw baffle, and the vertical band saw will cut the bone pieces that are exposed outside the bone piece groove 5 flat.

[0028] After the base 1 slides to the cutting completion position, continue to drag it to the handle 4, and lift the base 1 off the bone saw table to complete the bone block cutting. Then, pull the pressure plate 6 out of the slot to release the pressure on the bone block in the bone block groove 5, and you can take out the processed bone block.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
