Description

Technical Field

[0001] This utility model relates to the field of surgical instruments, specifically to a surgical instrument grinding head. Background Technology

[0002] In the medical field, burrs are commonly used in orthopedic and dental surgeries to cut, grind, or remove bone tissue. However, existing surgical instruments struggle to remove debris or crystals generated during surgery, requiring additional tools, consuming considerable time, and resulting in low efficiency. If debris or crystals are not removed promptly and effectively, they may remain in the body, causing complications such as inflammation and infection, and prolonging the patient's recovery time. Utility Model Content

[0003] This utility model addresses the aforementioned shortcomings in the prior art by providing a surgical instrument grinding head to solve at least one of the aforementioned technical problems.

[0004] A surgical instrument grinding head includes a grinding head body, the grinding head body including a grinding head end and a connecting end, the connecting end being used for detachable connection with an external device;

[0005] The grinding head body has a cavity inside, which extends through the grinding head body from the grinding head end to the connecting end; the cavity has multiple negative pressure holes at the grinding head end to form a negative pressure channel between the grinding head end and the connecting end.

[0006] In practical applications, the connecting end of the grinding head is used to connect to an external device. While the user is grinding or planing at the grinding head, the external device operates simultaneously. As a result, debris or crystals generated during grinding or planing can immediately enter the negative pressure port and be sucked into the negative pressure device through the negative pressure channel. This prevents tissue debris from accumulating in the surgical area, thus not affecting the doctor's field of vision. It also eliminates the need for additional devices to clean debris or crystals, simplifying the surgical procedure and shortening the operation time. Furthermore, in some applications, the reduced number of devices can further reduce the size of the incision. In some cases, the negative pressure channel at the grinding head can also absorb some blood when bleeding occurs at the surgical site, reducing local blood accumulation, making it easier for the doctor to locate the bleeding point, and facilitating appropriate hemostasis measures.

[0007] In some specific embodiments, the burr end is bent at a preset angle relative to the connecting end. In practical applications, the internal tissues and bone structures of the human body are complex, and some areas have narrow and tricky spaces. By setting a burr end with a bending angle, in orthopedic surgery, it is possible to better follow the anatomical shape of the bone to reach areas that are difficult to reach with conventional burrs, thereby accurately removing lesions and improving surgical efficiency.

[0008] In some specific embodiments, a grinding tip is provided on the grinding head end; the grinding tip protrudes relative to the grinding head end. By providing multiple grinding tips, the grinding efficiency of the grinding head end and the grinding precision of fine areas can be improved. It should be noted that this application does not specifically limit the specific shape, degree of protrusion, or number of grinding tips. In practical applications, as long as the grinding efficiency of the grinding head end and the grinding precision of fine areas can be achieved, the user can set the specific shape, degree of protrusion, distribution area, and number of grinding tips according to the actual application.

[0009] In some specific embodiments, multiple grinding heads are evenly arranged on the end of the grinding head. By setting multiple grinding heads, the grinding area at the end of the grinding head can be increased. In practical applications, the surfaces of human bones and tissues often present irregular shapes. Setting multiple grinding heads can better conform to the irregular shapes of human bones, enabling more precise grinding of the corresponding areas.

[0010] In some specific embodiments, the diameter of the negative pressure hole at the grinding head end is smaller than the diameter of the cavity. In practical applications, by setting the diameter of the negative pressure hole to be smaller than the diameter of the cavity, the diameter of the debris entering through the negative pressure hole is smaller than the diameter of the cavity, which can effectively reduce the risk of debris clogging in the negative pressure channel.

[0011] In some specific embodiments, a planing blade is formed on the edge of the negative pressure hole. In practical applications, when the thickness of the edge of the negative pressure hole is small, a sharp planing blade can be formed on the edge of the negative pressure hole. This planing blade can further improve the grinding capability of the grinding head end, and in surgical scenarios, the user can use it to plan the tissue.

[0012] In some specific embodiments, the negative pressure orifice includes one or more of the following: circular, elliptical, diamond-shaped, and strip-shaped. It should be noted that this application does not specifically limit the shape of the negative pressure orifice; in practical applications, users can set the shape of the negative pressure orifice according to actual needs.

[0013] In some specific embodiments, at least one negative pressure hole is located on the grinding head. By placing the negative pressure hole on the grinding head, the negative pressure hole can be closer to the point where debris is generated, allowing for the suction and removal of debris as soon as it is generated. This prevents debris from accumulating around the surgical site and improves the precision of the surgery.

[0014] In some specific embodiments, at least one engaging member is provided on the connecting end, which is used to engage with an external device.

[0015] In some specific embodiments, a wear-resistant coating, including a diamond-like carbon (DLC) coating, is provided on the grinding head end. This wear-resistant coating enhances the wear resistance of the grinding head end, maintains its precision, and further reduces the coefficient of friction between the grinding head end and the surgical site during use, reducing the power required by the grinding head end and lowering the heat generated by friction, which is beneficial for good wound healing after surgery. Beneficial effects: This application provides a surgical instrument grinding head, comprising a grinding head body, a grinding head end, and a connecting end. By forming multiple negative pressure holes in the grinding head end, a negative pressure channel is formed between the grinding head end and the connecting end. This allows debris and crystals generated during surgery to enter the negative pressure channel through the negative pressure holes, enabling rapid cleaning of tissue debris generated during the grinding and planing of tissues during surgery. This effectively improves the grinding intensity and precision of the grinding head, further enhancing surgical efficiency and accuracy. Attached Figure Description

[0035] Example

[0036] This application provides a surgical instrument grinding head, the specific solution of which is as follows:

[0037] A surgical instrument grinding head includes a grinding head body 1, which includes a grinding head end 11 and a connecting end 12, the connecting end 12 being used for detachable connection with an external device.

[0038] The grinding head body 1 has a cavity 2 inside, which extends through the grinding head body 1 from the grinding head end 11 to the connecting end 12. Multiple negative pressure holes 21 are formed in the cavity 2 at the grinding head end 11 to create a negative pressure channel between the grinding head end 11 and the connecting end 12. The overall structure of the grinding head body 1 is as follows: Figure 1 and Figure 3 As shown, its perspective structure is as follows Figure 2 and Figure 4 As shown.

[0039] In practical applications, the connecting end 12 of the grinding head body 1 is used to connect with the external device 3. The external device 3 includes a negative pressure device. During the grinding or planing process at the grinding head end 11, the external device 3 operates simultaneously. As a result, the debris or crystals generated by grinding or planing at the grinding head end 11 can immediately enter the negative pressure port 21 and be sucked into the negative pressure device through the negative pressure channel. This prevents tissue debris from accumulating in the surgical area, does not affect the doctor's observation field of the corresponding surgical area, and eliminates the need for additional devices to clean debris or crystals, simplifying the surgical procedure and shortening the operation time. In some application scenarios, the reduced number of devices can further reduce the size of the wound. In some cases, the negative pressure channel of the grinding head end 11 can also absorb some blood when bleeding occurs at the surgical site, reducing local blood accumulation, making it easier for the doctor to find the bleeding point, and also helping the doctor to take appropriate hemostatic measures.

[0040] In some specific embodiments, the grinding head end 11 is bent at a predetermined angle relative to the connecting end 12. The angle at which the grinding head end 11 is bent relative to the connecting end 12 is as follows: Figure 3 As shown by angle α. It should be noted that this application does not specifically limit the exact value of the bending angle; the bending angle can be set according to the user's specific needs in actual application.

[0041] In practical applications, the internal tissues and skeletal structures of the human body are complex, and some areas have narrow and tricky spaces. By setting the burr end 11 with a bending angle, it is possible to better follow the anatomical shape of the bone to reach areas that are difficult to reach with conventional burrs in orthopedic surgery, thereby accurately removing lesions and improving surgical efficiency.

[0042] In one specific embodiment, the grinding head body 1 further includes a transition portion 13, through which the grinding head end 11 is connected to the connecting end 12. In practical applications, by setting the transition portion 13, the transition of the grinding head body 1 from the connecting end 12 to the grinding head end 11 side can be more natural. The outer diameter of the transition portion 13 can be smaller than the outer diameter of the connecting end 12, so as to create a better surgical field of view for the user on the grinding head end 11 side.

[0043] In some specific embodiments, a grinding tip 111 is provided on the grinding head end 11; the grinding tip 111 protrudes relative to the grinding head end 11. By providing multiple grinding tips 111, the grinding efficiency of the grinding head end 11 and the grinding precision of fine areas can be improved. It should be noted that this application does not specifically limit the specific shape, degree of protrusion, or number of grinding tips 111. In practical applications, as long as the grinding efficiency of the grinding head end 11 and the grinding precision of fine areas can be improved, the user can set the specific shape, degree of protrusion, distribution area, and number of grinding tips 111 according to the actual application.

[0044] In some specific embodiments, multiple grinding heads 111 are evenly arranged on the grinding head end 11. By setting multiple grinding heads 111, the grinding area of ​​the grinding head end 11 can be increased. In practical applications, the surfaces of human bones and tissues often present irregular shapes. Setting multiple grinding heads 111 can better conform to the irregular shapes of human bones, and can more accurately grind the corresponding parts.

[0045] In some specific embodiments, the diameter of the negative pressure hole 21 at the grinding head end 11 is smaller than the diameter of the cavity 2. In practical applications, by setting the diameter of the negative pressure hole 21 to be smaller than the diameter of the cavity 2, the diameter of the debris entering through the negative pressure hole 21 is smaller than the diameter of the cavity 2, which can effectively reduce the risk of debris clogging in the negative pressure channel.

[0046] In some specific embodiments, a planing blade 22 is formed on the edge of the negative pressure hole 21. In practical applications, when the thickness of the edge of the negative pressure hole 21 is small, a sharp planing blade 22 can be formed on the edge of the negative pressure hole 21. This planing blade 22 can further improve the grinding capability of the grinding head end 11, allowing the user to perform tissue planing in surgical settings. Figure 5 and Figure 6 As shown, the grinding head 111 can be distributed in a strip shape on the grinding head end 11, forming a spiral structure together with the planing blade 22 to greatly improve the planing efficiency.

[0047] In some specific embodiments, the negative pressure hole 21 includes one or more of the following: circular hole, elliptical hole, rhomboid hole, and strip hole. It should be noted that this application does not specifically limit the shape of the negative pressure hole 21. In practical applications, users can set the shape of the negative pressure hole 21 according to actual needs.

[0048] In some specific embodiments, at least one negative pressure hole 21 is provided on the grinding head 111. By providing the negative pressure hole 21 on the grinding head 111, the negative pressure hole 21 can be closer to the place where debris is generated, so that the debris can be sucked up and removed at the first moment when the debris is generated, which can prevent the debris from accumulating around the surgical site and improve the accuracy of the surgery.

[0049] In some specific embodiments, such as Figure 7 , Figure 8 and Figure 9 As shown, at least one engaging member 121 is provided on the connecting end 12, which is used for engaging with the external device 3. It should be noted that this application does not specifically limit the specific shape and number of the engaging members 121. As long as it satisfies the engagement connection with the external device 3, the user can set the shape, size, and number of the engaging members 121 according to the actual situation. In a specific embodiment, a negative pressure inlet hole 23 is formed at one end of the connecting end 12 in the cavity 2. The engaging member 121 protrudes and / or is recessed along the edge of the negative pressure inlet hole 23 to engage with the external device 3.

[0050] In some specific embodiments, a wear-resistant coating, including a diamond-like carbon coating, is provided on the grinding head end 11. By providing this wear-resistant coating, the wear resistance of the grinding head end 11 can be enhanced, the precision of the grinding head end 11 can be maintained, and furthermore, the coefficient of friction between the grinding head end 11 and the surgical site during use can be reduced, the power required by the grinding head end 11 can be reduced, and the heat generated by friction can be reduced, which is conducive to good wound healing after surgery.

[0051] This embodiment provides a surgical instrument grinding head, including a grinding head body. The grinding head body includes a grinding head end and a connecting end. By forming multiple negative pressure holes in the grinding head end, a negative pressure channel is formed between the grinding head end and the connecting end. This allows debris and crystals generated during surgery to enter the negative pressure channel through the negative pressure holes, enabling rapid removal of tissue debris generated during the grinding and planing of tissues during surgery. This effectively improves the grinding intensity and fineness of the grinding head, further enhancing surgical efficiency and precision.

[0052] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
