Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an intervertebral processor. Background Art

[0002] In minimally invasive surgery for the intervertebral disc or spine, currently, mainly relying on the surgical experience of the surgeon, during the operation, soft tissues are removed little by little through a scraper or other tools. This highly tests a doctor's skills, has a long operation time, low removal efficiency, and as time goes by, the doctor's mind is prone to fatigue due to high concentration and may lead to mistakes, making it very easy to miss some places that are not easily noticed. At the same time, inexperienced doctors cannot perform the operation. Therefore, the requirements for the surgical operator are extremely high, greatly increasing the difficulty of the operation. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: to solve the problem that currently mainly relying on the surgical experience of the surgeon, soft tissues are removed through a scraper or other tools during the operation, with a long operation time, low removal efficiency, being prone to mistakes as time goes by, and extremely high requirements for the surgical operator, greatly increasing the difficulty of the operation. Now, an intervertebral processor is provided.

[0004] An intervertebral processor, comprising a brush rod, wherein bristles are arranged on the brush rod, the bristles are used for removing soft tissues between vertebrae, and a driving mechanism for driving the brush rod to rotate is arranged on the brush rod;

[0005] A protective cover is arranged on the driving mechanism, a cavity body is formed between the protective cover and the driving mechanism, the brush rod is located in the cavity body, a processing window is opened on the protective cover, the processing window is communicated with the cavity body, the bristles are located in the processing window, and one side of the bristles protrudes out of the processing window. Compared with the prior art, in this solution, the driving mechanism drives the brush rod to rotate, and drives the bristles on the brush rod to rotate. By controlling the reciprocating displacement of the bristles along the axial direction of the soft tissue, the soft tissues at the diseased site can be quickly removed, improving the operation efficiency. There is no need for manual removal of soft tissues little by little, and it can be operated without personal surgical experience, reducing the surgical requirements. By arranging a protective cover on the driving mechanism, the brush rod and the bristles are covered in the protective cover, and a processing window is opened on the protective cover to cover a part of the bristles. When the bristles remove soft tissues, the protective cover can effectively prevent the splashing of soft tissues and physiological saline, and also prevent unnecessary troubles caused by splashing.

[0006] To prevent soft tissues from accumulating in the cavity and affecting the rotation of the brush rod, thereby reducing the efficiency of the bristles in removing soft tissues, in some preferred embodiments, the cavity includes a treatment chamber and a communication chamber. The treatment chamber corresponds to and communicates with the treatment window. The communication chamber is provided at one end of the treatment chamber and is interconnected. A communication window is provided on the protective cover. The communication chamber is located between the treatment window and the communication window, and the communication window communicates with the communication chamber. There is a gap between the brush rod and the communication chamber. By providing a communication window, a communication chamber, and a treatment chamber that are interconnected on the protective cover, the centrifugal force of the bristles is greater than that of the brush rod during rotation. Therefore, the negative pressure at the treatment chamber is also greater. Thus, air is introduced through the communication window and conveyed towards the treatment chamber. On the one hand, it can remove the soft tissues accumulated in the cavity, ensuring the stable and reliable operation of the bristles. On the other hand, it can also clean the patient's part thoroughly, facilitating the doctor's observation of the affected area and improving the surgical efficiency.

[0007] To ensure the air intake volume, in some preferred embodiments, there are two communication windows which are oppositely arranged on both sides of the protective cover. By arranging the communication windows oppositely on both sides, the air intake volume of the communication windows is increased.

[0008] To better remove the soft tissues accumulated in the cavity, in some preferred embodiments, the cross-sectional area of the treatment chamber gradually increases from the driving mechanism towards the treatment window. By gradually increasing the cross-sectional area of the treatment chamber, the centrifugal force during the rotation of the bristles is increased. On the one hand, the bristles can fling out the soft tissues. On the other hand, the bristles generate a greater negative pressure and increase the air volume, better removing the soft tissues accumulated in the cavity.

[0009] To prevent the deflection of one end of the brush rod during use, in some preferred embodiments, a positioning hole matching the brush rod is provided at the end of the protective cover away from the driving mechanism, and one end of the brush rod is arranged in the positioning hole. By providing a positioning hole on the protective cover, the positioning hole positions one end of the brush rod, ensuring the stable and reliable rotation of the brush rod and avoiding the phenomenon of brush rod deflection.

[0010] In some preferred embodiments, the treatment window is arranged along the axial direction of the brush rod.

[0011] In some preferred embodiments, the treatment window is higher than the brush rod and lower than the bristles along the radial direction of the brush rod.

[0012] In some preferred embodiments, the protective cover is detachably installed on the driving mechanism.

[0013] The beneficial effects of the present invention are as follows: When the intervertebral processor of the present invention is in use, the driving mechanism drives the brush rod to rotate, and drives the bristles on the brush rod to rotate. By controlling the reciprocating displacement of the bristles along the axial direction of the soft tissue, the soft tissue at the diseased site can be quickly removed, improving the surgical efficiency. There is no need to manually remove the soft tissue bit by bit, and it can be operated without personal surgical experience, reducing the surgical requirements. By setting a protective cover on the driving mechanism, the brush rod and the bristles are covered in the protective cover, and a treatment window is opened on the protective cover to cover a part of the bristles. When the bristles remove the soft tissue, the protective cover can effectively prevent the splashing of the soft tissue and physiological saline, and also prevent unnecessary troubles caused by splashing, avoiding the problems of the existing method mainly relying on the surgical experience of the surgeon, removing the soft tissue with a scraper or other tools during the operation, having a long operation time, low removal efficiency, being prone to errors as time goes by, and having extremely high requirements for the surgical operator, which greatly increases the difficulty of the operation.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0028] As Figures 1-8 shown, an intervertebral processor includes a brush rod 1 and a driving mechanism 3. One end of the brush rod 1 is provided with bristles 2 for removing soft tissues between vertebrae, and the driving mechanism 3 is used to drive the brush rod 1 to rotate. In this embodiment, the driving mechanism is a rotary motor, and the rotary motor is connected to the brush rod 1 through a coupling and drives the brush rod 1 to rotate along its central axis.

[0029] Due to the requirements of the surgical environment, normal saline is continuously added to the surgical site of the patient during the operation. Therefore, in order to prevent the splashing of normal saline and soft tissues when the brush bristles 2 rotate, which may affect the operation and the surrounding environment, in this solution, a protective cover 4 is provided on the driving mechanism 3. A cavity body 5 is formed between the protective cover 4 and the driving mechanism 3. The brush rod 1 is located inside the cavity body 5. A treatment window 6 is opened on the protective cover 4. The treatment window 6 communicates with the cavity body 5. The brush bristles 2 are located inside the treatment window 6, and one side of the brush bristles 2 protrudes from the treatment window 6. The brush bristles 2 facing the soft tissues in the treatment window 6 are used for removal, while the protective cover 4 covers the rest, greatly reducing the splashing of normal saline and soft tissues and improving the surgical efficiency.

[0030] The cavity body 5 includes a treatment cavity 7 and a communication cavity 8 that communicate with each other. The treatment cavity 7 corresponds to and communicates with the treatment window 6. The communication cavity 8 is arranged at one end of the treatment cavity 7. A communication window 9 is opened on the protective cover 4. The communication cavity 8 is located between the treatment window 6 and the communication window 9. The communication window 9 communicates with the communication cavity 8. There is a gap between the brush rod 1 and the communication cavity 8 to form an air inlet channel. There are two communication windows 9 and they are oppositely arranged on both sides of the protective cover 4. The cross-sectional area of the treatment cavity 7 gradually increases from the driving mechanism 3 towards the treatment window 6. A positioning hole 10 matching the brush rod 1 is provided at one end of the protective cover 4 away from the driving mechanism 3. One end of the brush rod 1 is arranged in the positioning hole 10.

[0031] The treatment window 6 is arranged along the axial direction of the brush rod 1. The treatment window 6 is higher than the brush rod 1 and lower than the brush bristles 2 along the radial direction of the brush rod 1.

[0032] The protective cover 4 is threadedly connected to the driving mechanism 3 to achieve the detachable installation between the protective cover 4 and the driving mechanism 3.

[0033] When the above-mentioned intervertebral processor is in use, the rotation motor at the driving mechanism 3 drives the brush rod 1 to rotate. The brush rod 1 drives the brush bristles 2 to rotate. The brush bristles 2 come into contact with the soft tissues to be removed. The operation is similar to the process of brushing teeth. By continuously reciprocating and displacing at the patient's site, the brush bristles 2 remove the soft tissues. The positioning hole 10 ensures the stable and reliable rotation of the brush rod 1, preventing the brush rod 1 from deflecting and ensuring the stable and reliable operation of the brush bristles 2. At the same time, as the brush bristles 2 rotate at high speed and generate centrifugal force, the centrifugal force causes a negative pressure to be generated in the treatment cavity 7. The negative pressure causes the air outside the communication window 9 to be introduced into the communication window 9 and is transported to the treatment cavity 7 through the communication cavity 8. Since the cross-sectional area of the treatment cavity 7 gradually increases from the driving mechanism 3 towards the treatment window 6, there is no pressure loss when the air enters the treatment cavity 7, ensuring a large amount of air is continuously transported to the treatment cavity 7. On the one hand, it can blow away the soft tissues accumulated in the cavity body 5 to prevent the accumulated soft tissues from affecting the work of the brush bristles 2. On the other hand, the large amount of incoming air blows the soft tissues away from the affected area, facilitating the doctor's observation of the affected area and improving the surgical efficiency.

[0034] Based on the inspiration of the ideal embodiments of the present invention described above, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
