[0002] Medical saw blade is an important tool in orthopedic surgical instruments, and is usually made of high-strength stainless steel or hard alloy, has the characteristics of sharp and durable, and is accurate in operation. It is mainly used in bone cutting, orthopedic surgery, fracture reduction fixation, joint replacement and other medical operations involving bone cutting.

[0003] In the prior art, a medical saw blade for a power bone saw is disclosed in Chinese patent CN205094538U, which comprises a body in the form of a sheet, the body comprising a blade edge, a saw body and a joint, the blade edge, the saw body and the joint being integrally formed into a saw blade, the blade edge being provided with serrations; characterized in that the blade edge is in the form of a trapezoid, and a heat dissipation groove one is provided at the connection between the blade edge and the saw body; the saw body is provided with scale lines; the joint is provided with a positioning hole, which facilitates the installation of the saw blade on the medical power bone saw; and the front end of the saw body is provided with a heat dissipation groove two.

[0004] At present, most medical saw blades generate a large amount of bone chips during sawing. Since the existing saw blades have no bone chip outlet, a large amount of bone chips can only accumulate between the serrations. As the sawing proceeds, the bone chips will block the entire serrations, causing an increase in sawing resistance and cutting dullness, thereby making it inconvenient to use. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a medical saw blade for convenient chip removal to solve the problems in the above background.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a medical saw blade for convenient chip removal, comprising a saw blade body, a plurality of serrations are fixedly connected to one end of the saw blade body, a chip removal groove one is formed between any two adjacent serrations at one end of the saw blade body, a plurality of chip removal grooves two are formed on one side of the saw blade body, and one side of the plurality of chip removal grooves two is in communication with one side of the chip removal groove one.

[0007] As a further optimization of the technical scheme, a heat dissipation hole is formed through the other side of the saw blade body.

[0008] As a further optimization of the technical scheme, scale grooves are formed on both sides of the saw blade body.

[0009] As a further optimization of the technical scheme, a joint is fixedly connected to the other end of the saw blade body, and a positioning hole is formed in one end of the joint.

[0010] This utility model provides a medical saw blade that facilitates chip removal, and has the following beneficial effects:

[0011] This invention utilizes the structural design of chip removal groove one and chip removal groove two. Chip removal groove one guides the bone chips between two adjacent saw teeth to be discharged. As the sawing depth increases, chip removal groove one enters the sawing surface, and chip removal groove two guides the bone chips in chip removal groove one to be discharged. This structure achieves the discharge of bone chips between saw teeth, reduces sawing resistance, and shortens the operation time. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] This utility model provides a technical solution: such as Figure 1 - Figure 3 As shown in this embodiment, a medical saw blade with convenient chip removal includes a saw blade body 1. One end of the saw blade body 1 is fixedly connected to multiple saw teeth 6. A chip removal groove 7 is opened at one end of the saw blade body 1 between any two adjacent saw teeth 6. Multiple chip removal grooves 8 are opened on one side of the saw blade body 1. One side of the multiple chip removal grooves 8 is connected to one side of the chip removal groove 7. Through the structural design of the chip removal grooves 7 and 8, the chip removal groove 7 guides the bone chips between two adjacent saw teeth 6 to be discharged. As the sawing depth increases, the chip removal groove 7 enters the sawing surface, and the chip removal grooves 8 guide the bone chips in the chip removal groove 7 to be discharged. This structure realizes the discharge of bone chips between the saw teeth 6, reduces sawing resistance, and shortens the operation time. The chip removal groove 7 is opened between every two adjacent saw teeth 6.

[0018] like Figure 1 and Figure 2 As shown, a heat dissipation hole 2 is provided through the other side of the saw blade body 1. When the saw blade body 1 is used, the saw blade body 1 will generate heat. The heat dissipation hole 2 is used to dissipate heat from the saw blade body 1, ensuring the safety of the operation.

[0019] As Figure 1 and Figure 2 shown, the saw blade body 1 is provided with a scale groove 3 on both sides, the saw blade body 1 can be accurately positioned and measured in the process of use The depth or length of cutting improves the accuracy and success rate of the operation.

[0020] As Figure 1 and Figure 2 shown, the other end of the saw blade body 1 is fixedly connected with the joint 4, and the one end of the joint 4 is provided with the positioning hole 5, and the structure design of the joint 4 and the positioning hole 5 can be fixedly installed on the cutting equipment.

[0021] The utility model provides a medical saw blade convenient to chip, and the specific working principle is as follows:

[0022] When using the medical saw blade, first, the joint 4 is installed on the cutting equipment, and when cutting, the plurality of chip grooves one 7 on the saw blade body 1 guide the bone chips between two adjacent saw teeth 6 to be discharged, along with the increase of sawing depth, the chip groove one 7 enters into the sawing surface, and the chip groove two 8 guides the bone chips in the chip groove one 7 to be discharged, realize the bone chips between the saw teeth 6 to be discharged, reduce the sawing resistance, shorten the operation length.

[0023] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and its equivalents.
