[0031] It should be understood that although the terms first, second, third, etc. may be used in this specification to describe various information, this information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this specification, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0032] The surgical tool of this specification is described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0033] Figure 1 A cross-sectional view of a vibration-absorbing drill grinder provided in this specification, such as Figure 1 As shown, the shock-absorbing drill grinder comprises a drill bit 1, a flexible sleeve 2, a flexible shell 3, a drill grinder shell 4 and a drill grinder rod 5, wherein the flexible material part is marked with shadows.

[0034] in, Figure 1 The cross-sectional view shows that the grinding drill rod 5 is long. To facilitate the observation of the structure, this specification also provides Figure 1 The structural cross-section of the drill bit end of the medium vibration-absorbing drill, such as Figure 2As shown, one end of the drill rod 5 is connected to the drill head 1, and the other end is connected to the driving device, the flexible sleeve 2 is sleeved on the drill rod 5, the outer wall of the flexible sleeve 2 abuts against the inner wall of the drill housing 4, and the outer side of the drill housing 4 sleeves the flexible housing 3. When the shock-absorbing drill is used, it is inserted into the surgical instrument channel of the endoscope, so that the flexible housing 3 abuts against the inner wall of the surgical instrument channel.

[0035] Here is an additional explanation. Figure 2 In order to accurately demonstrate the structure, the embodiment only takes the flexible sleeve 2 located at the drill bit end of the shock-absorbing drill as an example for explanation, and does not limit the flexible sleeve 2 to be located only at the drill bit end. In other words, the position of the flexible sleeve 2 located at the shock-absorbing drill is not limited in this specification and can be set as needed.

[0036] Before the operation, the shock-absorbing burr is inserted into the surgical instrument channel in the endoscope, the burr head 1 is placed in the preset surgical area, and the driving device is started to drive the burr rod 5 and the connected burr head 1 to move. During the operation, the flexible sleeve 2 reduces the vibration of the burr rod centrifugal movement on the burr housing 4 by means of buffering. Similarly, the flexible housing 3 further reduces the vibration of the burr housing 4 on the surgical instrument channel in the endoscope by means of buffering, so that the endoscope can obtain a stable image of the surgical area when the shock-absorbing burr is working, thereby improving the accuracy of the operation.

[0037] In one or more embodiments of the present specification, the flexible housing 3 is cylindrical, and the shock-absorbing drill grinder further comprises: a retaining ring 6 on the outside of the drill grinder housing 4 .

[0038] Specifically, this specification also provides a structural cross-sectional view of a shock-absorbing grinding drill, such as Figure 3 As shown, the clamp ring 6 ensures that the flexible housing 3 does not fall off during surgery. In addition, the diameter of the clamp ring 6 is not greater than the diameter of the flexible housing 3. The purpose is to enable the flexible housing 3 to fully exert its buffering function, so the clamp ring 6 used to fix the flexible housing 3 should not contact the surgical instrument channel.

[0039] In one or more embodiments of the present specification, the flexible housing 3 is annular, and a groove is provided on the outer side of the grinding drill housing 4.

[0040] Specifically, this specification also provides a cross-sectional view of a vibration-absorbing grinding drill, such as Figure 4 As shown, the right rectangle is a schematic diagram of the shape of the annular housing 3. When the flexible housing 3 is annular, a groove is set on the drill housing 4 to fix the flexible housing 3 at the groove position to prevent the annular flexible housing 3 from falling off. For a clear structure, a structural cross-sectional diagram of the drill head end of the shock-absorbing drill is also provided, as shown in FIG. Figure 5 As shown, the annular shape of the annular flexible housing 3 is not limited to a square ring. If it is a center ring, the groove on the grinding drill housing 4 can be set to a corresponding arc groove. The specification does not limit the specific annular shape and it can be set as needed.

[0041] Additional explanation is required here. Figure 5 It is a schematic diagram of the drill bit end of the flexible shell 3. The closer the flexible shell is to the drill bit 1 of the flexible shell 3, the better the effect. However, the flexible shell 3 is not limited to being located at the drill bit end of the shock-absorbing drill bit. In other words, the position of the flexible shell 3 is not limited in this specification and can be set as needed.

[0042] In the above embodiments of this specification, there are multiple flexible shells 3 which are evenly distributed on the drill shell 4 .

[0043] Specifically, this specification also provides a structural cross-sectional view of a shock-absorbing grinding drill, such as Figure 6 As shown, the multiple flexible shells 3 evenly distributed on the bur shell 4 further reduce the influence of the deformation of the bur shell 4 on the surgical instrument channel, making the endoscope more stable.

[0044] In one or more embodiments of the present specification, the flexible sleeve 2 is located at a side where the drill grinding rod 5 is connected to the drill grinding bit 1 .

[0045] Specifically, Figure 2 As shown, under the condition that the number of flexible sleeves 2 is limited, according to the characteristic that the movement generated by the drill grinder is eccentric movement, that is, the impact on the end of the drill grinder rod 5 connected to the drill grinder bit 1 is greater and the amplitude is large. Correspondingly, the buffering effect of the flexible sleeve 2 on the side where the drill grinder rod 5 is connected to the drill grinder bit 1 is much greater than that of the flexible sleeve 2 being separately set at other positions of the drill grinder rod 5.

[0046] In one or more embodiments of the present specification, there are multiple flexible sleeves 2 that are evenly distributed on the drill rod 5 .

[0047] Specifically, this specification also provides a structural cross-sectional view of a shock-absorbing grinding drill, such as Figure 7 As shown, in order to reduce the influence of the deformation of the drill grinding rod 5 on the drill grinding housing 4, a plurality of flexible sleeves 2 evenly distributed on the drill grinding rod 5 can obtain a good buffering effect.

[0048] In one or more embodiments of the present specification, one of the inner side and the outer side of the flexible sleeve 2 has a lubricating coating.

[0049] Specifically, this specification also provides a structural cross-sectional view of a drill bit end of a vibration-absorbing drill grinder, such as Figure 8 As shown, in order to ensure that the working efficiency of the vibration-absorbing grinding drill is not affected by the flexible sleeve 2, Figure 8 The inner side of the flexible sleeve 2 shown in shadow is prepared with a lubricating coating or Fig. 9 The outer side of the flexible sleeve 2 shown in shadow is prepared with a lubricating coating to reduce the friction force of the flexible sleeve 2 against the drill grinding housing 4 when rotating, or reduce the friction force of the drill grinding rod 5 against the flexible sleeve 2.

[0050] In one or more embodiments of the present specification, the bur rod 5 is snap-connected to the driving device, and the bur housing 4 is snap-connected to the surgical robot.

[0051] Specifically, the grinding drill rod 5 needs to be stably connected to the driving device to ensure the working efficiency of the driving device. In addition, this specification also provides a schematic diagram of a shock-absorbing grinding drill connected to a surgical robot, such as Fig.10 As shown, when the shock-absorbing grinding drill is working under the control of the surgical robot, the surgical robot does not have a buffer structure for fixing surgical instruments, so the use of the shock-absorbing grinding drill has a good effect.

[0052] based on Figure 1 The shock-absorbing drill shown in the embodiment of the specification can reduce the adverse effects of the drill on the surgical site and the endoscope during operation during minimally invasive spinal endoscopic surgery, provide stability for the endoscope during surgery, and reduce the probability of surgical errors.

[0053] The above is only a preferred embodiment of this specification and does not limit this specification in any form. Although this specification has been disclosed as a preferred embodiment, it is not used to limit this specification. Any technician familiar with this profession can make some changes or modify the technical content disclosed above into an equivalent embodiment with equivalent changes without departing from the scope of the technical solution of this specification. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of this specification without departing from the content of the technical solution of this specification still falls within the scope of the technical solution of this specification.
