Description

TECHNICAL FIELD

[0001] The present application relates to the field of orthopedic surgery technology, in particular to a multifunctional electric bone drill for orthopedic surgery. BACKGROUND

[0002] The multifunctional electric bone drill for orthopedic surgery is a kind of electric surgical instrument specially designed for orthopedic surgery, which has multiple functions and configurations to meet different surgical needs. This electric bone drill is driven by an electric motor to provide a high-speed rotating drill bit for cutting, drilling and sawing bone operations.

[0003] In the Chinese patent with the patent publication number CN104306045A, a bone chip anti-splashing bone drill is disclosed, which includes a bone chip protection device, the bone chip protection device includes a protective cover installed between the drill bit and the electric drill, an auxiliary protection shell, the drill bit passes through the protective cover, the protective cover is adjacent to the drill bit, the lower end of the protective cover is provided with a guide groove communicated therewith, the guide groove and the auxiliary protection shell are connected through a connecting pipe, the connecting pipe is provided with openings between the guide groove and the auxiliary protection shell respectively, the auxiliary protection shell is provided with a chip removing gear, a rotating shaft passes through the center of the chip removing gear, the auxiliary protection shell is communicated with a conduit located below it, which can effectively prevent the bone chips generated during the use of the bone drill from splashing everywhere, reduce the impact on the operator, make the surgical operation more accurate, and ensure the safety of the patient.

[0004] However, the device in the above-mentioned reference and the existing technology still has the following defects in actual use:

[0005] 1. Compared with the device in the above-mentioned reference, the bone chips and flesh generated during the operation process are covered in the protective cover to prevent splashing, the accumulated bone chips and flesh enter the auxiliary protection shell through the connecting pipe, and the bone chips are sent into the conduit under the rotation of the chip removing gear, thereby uniformly collecting and processing, which can effectively ensure the operation;

[0006] In actual use, although the setting of the protective cover can prevent the splashing of bone chips and flesh, it will also block the doctor's view to some extent. In orthopedic surgery, the doctor needs to clearly observe the situation of the drilling site to ensure the accuracy and safety of the operation. However, the protective cover makes it difficult for the doctor to directly see the specific situation of the drilling, especially when performing delicate operations, which will affect the doctor's judgment of the drilling depth, direction, etc.

[0007] Moreover, the bone chips and flesh may be blocked during the process of passing through the connecting pipe, auxiliary protection shell and conduit due to the large size of the bone chips and the adhesion of the flesh. Once blocked, it needs to be cleaned in time, otherwise it will affect the collection and processing effect of the bone chips and flesh, and even cause the device to malfunction.

[0008] 2. Compared with the conventional bone drills that generally use threaded shapes, the threaded spaces formed between the threads can be used as channels for bone chips. During the drilling process, the bone chips generated will be carried out of the drilling area along the thread lines.

[0009] In actual use, the gaps between the threads can easily become hiding places for substances such as bone chips and blood. During the drilling process, bone chips and blood will enter the deep gaps as the threads rotate. Due to the special structure of the gaps, these substances are difficult to completely remove with routine cleaning. Even after multiple cleaning operations, some residual substances may still remain at the bottom or corners of the gaps. The residual bone chips and blood are rich in nutrients, providing an ideal environment for the growth and reproduction of bacteria. If these residual substances are not thoroughly removed in a timely manner, bacteria will rapidly multiply under suitable temperature and humidity conditions, and then seriously threaten the health and safety of the patient when the bone drill is used in the next surgery.

[0010] In view of this, the present invention proposes a multifunctional electric bone drill for orthopedic surgery to remedy and improve the shortcomings of the prior art. Summary of the Invention

[0015] By adopting the above technical solution, the rotational force of the reciprocating wire shaft itself is transmitted to the nut sleeve through the continuous rotation of the reciprocating wire shaft, thereby driving it to move back and forth in a straight line.

[0016] Further, the surface of the nut sleeve plate is provided with a treatment pad corresponding to the part of the reciprocating wire shaft outer wall thread groove, and the treatment pad is made of soft hair brush, i.e. artificial fiber material.

[0018] Further, the surface of the nut sleeve plate is provided with an abutting ball, and the inside of the treatment cylinder is provided with a prompt rod, and the triangular plate inclined surface part in the prompt rod is located on the movement path of the abutting ball.

[0019] By adopting the above technical scheme, the abutting ball triggers the prompt rod to move out from the specific position of the treatment cylinder, and this action can be used as a prompt signal for bone drilling time interval.

[0020] Further, a communication pipe is connected to the center position of the treatment cylinder, a one-way valve is installed at the connection position of the communication pipe and the treatment cylinder, and the communication pipe is rotationally connected to the inside of the threaded drill bit.

[0023] Further, a dynamic auxiliary mechanism is arranged on the outside of the bone drill shell, which is used to assist the threaded drill bit in all-around adjustment, and the dynamic auxiliary mechanism comprises a supporting ring arranged on the outside of the bone drill shell, the inner side wall of the supporting ring is uniformly fixedly connected with a fitting pad, the inside of the supporting ring is uniformly provided with a ball, an elastic plate and a shaft column, the outer wall of the supporting ring is rotationally connected with an adjusting ring, the lower surface of the supporting ring is symmetrically hinged with a support plate, and one end of the support plate away from the supporting ring is provided with an adaptive piece.

[0024] Further, the elastic plate is in a corrugated shape, the inside of the adjusting ring is uniformly provided with an inclined groove corresponding to the position of the shaft column, and the supporting ring and the shaft column are in sliding connection through the inclined groove.

[0025] By adopting the above technical scheme, the shaft column is moved by extrusion through the inclined groove, and then the position of the bone drill shell is stabilized according to the need.

[0026] Further, the adaptive piece is in an incomplete circular arc shape, the adaptive piece is made of rubber material, and the inner side wall of the adaptive piece is uniformly provided with a ball.

[0027] By adopting the technical scheme, the spherical ball can form a certain spacing space when being attached to a human body part.

[0028] Further, the driving module comprises a driving motor, a battery and a main shaft, the driving motor in the driving module is responsible for providing operating power, the battery in the driving module is responsible for providing power for the driving motor, and the reciprocating wire shaft is fixedly connected to the outer wall of the main shaft in the driving module.

[0029] Compared with the prior art, the present application has the following advantages:

[0030] (1) The device, through the operation of the driving motor, causes the inside of the processing cylinder to form a negative pressure to generate suction when the threaded drill bit is working due to the movement of the nut sleeve plate. First, the suction directly acts on the working position of the threaded drill bit, i.e. the human bone part, through the branch pipes, thereby improving the absorption efficiency of bone chips generated during drilling, effectively reducing the residual debris in the surgical area, providing a clearer surgical field for the doctor, and helping to improve the accuracy and efficiency of the operation. Secondly, the continuous suction also synchronously removes the heat generated during drilling, which can maintain the appropriate temperature of the surgical site and reduce the adverse effects of heat damage on the bone and surrounding tissue, thereby helping the patient to recover quickly after the operation and reducing the incidence of postoperative complications.

[0031] Among them, the branch pipes are uniformly distributed around the threaded drill bit main body and are used in cooperation with the connecting spray ring, thereby expanding the suction area and covering all directions of the drilling area to ensure that the bone chips are efficiently collected. In addition, the multi-channel design can simultaneously suck bone chips from multiple directions, improving the overall efficiency of the suction system and reducing the load of a single suction point.

[0032] Among them, when the threaded drill bit rotates for a certain period of time, the abutting ball will trigger the prompt rod to move out from a specific position of the processing cylinder. This action can serve as a prompt signal for the time interval of bone drilling, ensuring that medical personnel can accurately control the time of each bone drilling, thereby helping to maintain the stability and consistency of the operation, reducing the operation errors caused by time differences, and at the same time, ensuring the uniformity of the time of each bone drilling can also reduce the risk of damage to the patient's tissue and improve the safety and success rate of the operation.

[0033] Among them, the surface of the nut sleeve plate is provided with a treatment pad made of soft brush material corresponding to the position of the thread groove of the outer wall of the reciprocating wire shaft. This not only maintains the cleanliness of the outer wall of the reciprocating wire shaft, but also ensures the stability and efficiency of the structure operation. The clean reciprocating wire shaft can reduce friction and wear, prolong the service life, and ensure that the reciprocating linear motion of the nut sleeve plate on its outer wall is smoother.

[0034] Especially important is that first, the circular holes opened at the positions of the thread groove of the thread drill and the surface of the communication pipe are staggered in the initial state, so as not to affect the normal use of the thread drill, and this design ensures that the performance and efficiency of the drill in normal work will not be affected by the circular holes, and second, when it is necessary to clean the residues in the thread groove, only need to simply rotate the communication pipe, so that the circular holes on the communication pipe and the circular holes on the thread drill correspond to each other, at this time, start the thread drill again, the suction and thrust formed in the processing cylinder will directly act on the position of the thread groove through these circular holes, this design makes the cleaning process simple and efficient, without disassembling the drill or performing complex operations, through this way, the bone chips, impurities and the like in the thread groove can be easily removed, keeping the drill clean and sharp, which not only improves the service life of the drill, but also ensures the stability and accuracy of the operation or processing process;

[0035] (2) The device is introduced by introducing a dynamic auxiliary mechanism, first, the adaptive piece is adaptively changed in shape and installed on the limb bone and joint parts of the patient, second, through the cooperation of the elastic plate in the internal interval layer of the supporting ring and the ball, the bone drill shell part realizes free rotation in multiple dimensions, up to 360° omnidirectional rotation, this feature is particularly important when performing complex part surgery, such as irregular bone regions of the spine, pelvis, etc., the doctor does not need to adjust his own posture and hand position greatly, but can easily change the drilling direction, thereby significantly improving the accuracy and efficiency of the operation, and this design reduces the operation difficulty and time, reduces the operation risk, and also relieves the physical burden of the doctor;

[0036] Among them, the elastic plate as a whole adopts a corrugated shape design, which enables the elastic plate to deform and recover flexibly like a wave when subjected to external force, thereby enhancing its elasticity and toughness, and the corrugated shape can effectively disperse and absorb external force, when the external force acts on the elastic plate, the corrugated shape design can disperse the external force to a larger area, thereby reducing the stress intensity per unit area;

[0037] Among them, the adaptive piece as a whole is designed as an incomplete circular arc, which can better fit the curves of different parts of the human body, ensuring contact between the adaptive piece and the human body, this curve fitting degree not only improves the stability of the device, but also prevents sliding or displacement during use, thereby ensuring the accuracy and safety of the operation, secondly, the inner side wall of the adaptive piece is uniformly provided with spherical balls, which can form a certain interval space when fitting the human body part, through this interval space, not only provides a basis for air flow, prevents the part from sweating, but also enhances the air permeability and heat dissipation performance of the adaptive piece, thereby effectively reducing the accumulation of sweat, keeping the operation part dry and clean, thereby reducing the risk of infection;

[0038] Especially important is that the inside of the supporting ring is designed with multiple slidable shaft columns, the shaft columns are moved by triggering the form by artificial adjustment, when it is needed to continuously drill the bone in a certain position, the doctor can rotate the adjusting ring to drive the shaft columns to move out, so as to ensure that the bone drill position remains unchanged, and the bone drill always keeps an angle unchanged with the operation position, the design not only enhances the stability of the operation, but also improves the accuracy and reliability of the drilling, avoids the operation failure and patient injury caused by the position deviation of the bone drill, further guarantees the safety of the operation and the health of the patient.

Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application;

[0055] It should be noted that the structure and working principle of the handle frame 1, the bone drill shell 11, the drive module 12 and the threaded drill bit 13 are prior art, which will not be described here.

[0056] Embodiment 1

[0057] Please refer to Figure 1 and Figure 2 A multifunctional electric bone drill for orthopedic surgery is shown, which comprises a handle frame 1, a bone drill shell 11 is installed above the handle frame 1, a drive module 12 is installed on the rear side of the bone drill shell 11, a threaded drill bit 13 is installed on the front side of the bone drill shell 11, and a comprehensive processing mechanism 2 is provided on the outside of the bone drill shell 11, which is used for chip removal and cooling treatment of the threaded drill bit 13.

[0058] It should be noted that the drive module 12 includes a drive motor, a battery and a main shaft, the drive motor in the drive module 12 is responsible for providing running power, the battery in the drive module 12 is responsible for providing power for the drive motor, and the reciprocating wire shaft 21 is fixedly connected to the outer wall of the main shaft in the drive module 12.

[0059] Please refer to Figures 2 to 6 The comprehensive processing mechanism 2 includes a reciprocating wire shaft 21 installed on the outside of the bone drill shell 11, a nut sleeve plate 22 is installed on the outside of the reciprocating wire shaft 21, a processing cylinder 24 is installed on the outside of the nut sleeve plate 22, branch pipes 27 are uniformly installed on the side wall of the processing cylinder 24, and connecting spray rings 28 are communicated with one end of the branch pipes 27 away from the processing cylinder 24.

[0060] Need to explain, the outer wall of the reciprocating wire shaft 21 is provided with a cross-shaped thread groove, the reciprocating wire shaft 21 and the nut sleeve plate 22 constitute a ball screw structure, and the nut sleeve plate 22 is initially located inside the processing cylinder 24 close to one end of the threaded drill bit 13, the surface of the nut sleeve plate 22 is provided with a processing pad 23 corresponding to the position of the thread groove of the outer wall of the reciprocating wire shaft 21, the processing pad 23 is composed of soft hair brush, i.e. artificial fiber material, the surface of the nut sleeve plate 22 is provided with an abutting ball 25, the inside of the processing cylinder 24 is provided with a prompt rod 26, the triangular plate inclined surface part in the prompt rod 26 is located on the movement path of the abutting ball 25, the center position of the processing cylinder 24 is communicated with a communication pipe 29, a one-way valve is installed at the connection position of the communication pipe 29 and the processing cylinder 24, the communication pipe 29 is rotationally connected to the inside of the threaded drill bit 13, the surface of the communication pipe 29 and the threaded groove position of the threaded drill bit 13 are both provided with a circular hole 210, the circular hole 210 on the surface of the communication pipe 29 is in an initial state of staggered with the circular hole 210 at the threaded groove position of the threaded drill bit 13.

[0061] Specifically, since the reciprocating wire shaft 21 is fixedly connected to the outer wall of the main shaft in the driving module 12, when the main shaft remains rotating, it will synchronously drive the reciprocating wire shaft 21 to rotate, since the reciprocating wire shaft 21 and the nut sleeve plate 22 constitute a ball screw structure, and the pitch of the reciprocating wire shaft 21 is equivalent to the inner diameter size of the nut sleeve plate 22, and the tangent of the thread and the cylinder is greater than 45 degrees with the horizontal plane, and then when the reciprocating wire shaft 21 remains rotating, the rotating force of the reciprocating wire shaft 21 can be smoothly transmitted to the nut sleeve plate 22, and then drive it to move along the surface of the reciprocating wire shaft 21, since the outer wall of the reciprocating wire shaft 21 is provided with a cross-shaped thread groove, therefore the moving mode of the nut sleeve plate 22 is reciprocating;

[0062] Based on the above description that the nut sleeve plate 22 moves in a reciprocating manner, and since the nut sleeve plate 22 is initially located inside the processing cylinder 24 close to one end of the threaded drill bit 13, when the nut sleeve plate 22 starts to move, the space between the processing cylinder 24 and the nut sleeve plate 22 gradually increases, and at this time the air pressure inside the processing cylinder 24 is less than the air pressure outside the processing cylinder 24, and then the inside of the processing cylinder 24 will generate suction force, since the one-way valve is installed at the connection position of the communication pipe 29 and the processing cylinder 24, and the one-way valve is initially in an open and closed state, when the suction force acts on the one-way valve, the one-way valve will change to a closed state, and then the suction force generated inside the processing cylinder 24 will act on the outside from the branch pipe 27;

[0063] And, since the surface of the nut sleeve plate 22 is provided with the abutting ball 25, the inside of the processing cylinder 24 is provided with the prompt rod 26, the triangular plate inclined surface part in the prompt rod 26 is located on the movement path of the abutting ball 25, therefore, with the rotation of the threaded drill bit 13, and the linear movement of the nut sleeve plate 22, finally makes the abutting ball 25 extrude the prompt rod 26 until it is extruded from the inside of the processing cylinder 24, so as to realize the prompt effect;

[0064] At this time, the staff can stop continuing to drill bone work, and move the equipment out of the operation area, at the same time, rotate the communication pipe 29, so that the communication pipe 29 and the circular hole 210 on the surface of the threaded drill bit 13 keep coinciding, at this time, continue to start the equipment, because the nut sleeve plate 22 has been mentioned above has moved to the position of the prompt rod 26, therefore, with the continuous rotation of the reciprocating wire shaft 21, the nut sleeve plate 22 will move back, at this time, the space between the nut sleeve plate 22 and the processing cylinder 24 gradually becomes smaller, and at this time the air pressure inside the processing cylinder 24 is greater than the air pressure outside the processing cylinder 24, so that the processing cylinder 24 inside generates a thrust, when this thrust acts on the one-way valve again, the one-way valve is turned from the closed state to the initial open state, so as to ensure that the thrust inside the processing cylinder 24 can also act on the outside through the communication pipe 29, and then act on the threaded groove position of the threaded drill bit 13 through the circular hole 210.

[0065] Embodiment 2

[0066] Based on embodiment 1, please refer to Figures 7 to 11 As shown in the figure, the outside of the bone drill shell 11 is provided with a dynamic auxiliary mechanism 3, which is used to assist the threaded drill bit 13 to make all-round adjustment, the dynamic auxiliary mechanism 3 includes a supporting ring 31 installed on the outside of the bone drill shell 11, the inner side wall of the supporting ring 31 is uniformly fixedly connected with a matching pad 32, the inside of the supporting ring 31 is uniformly provided with a ball 33, a elastic plate 34 and a shaft column 35, the outer wall of the supporting ring 31 is rotationally connected with an adjusting ring 36, the lower surface of the supporting ring 31 is symmetrically hinged with a support plate 38, and the end of the support plate 38 away from the supporting ring 31 is uniformly provided with an adaptive piece 39.

[0067] It should be noted that the elastic plate 34 is in a whole corrugated shape, the inside of the adjusting ring 36 is uniformly provided with a bevel groove 37 corresponding to the position of the shaft column 35, the supporting ring 31 and the shaft column 35 are slidably connected through the bevel groove 37, the adaptive piece 39 is in an incomplete arc shape, the adaptive piece 39 is made of rubber material, and the inner side wall of the adaptive piece 39 is uniformly provided with a ball.

[0068] Specifically, the adapter piece 39 is attached to both sides of the patient's surgical site, thereby ensuring the stability of the position of the dynamic auxiliary mechanism 3. When using the device, the bone drill shell 11 needs to be passed through the support ring 31. At this time, the shaft column 35 is retracted inside the support ring 31, and the elastic plate 34 and the ball 33 inside the support ring 31 are in an active state. Therefore, the bone drill shell 11 can rotate freely in multiple dimensions inside the support ring 31, achieving 360° omnidirectional rotation. This state is suitable for complex bone surgery such as the spine and pelvis. The doctor can easily change the drilling direction without having to adjust his posture or hand position significantly.

[0069] When it is necessary to drill continuously at a site, the doctor rotates the adjusting ring 36, which triggers the shaft column 35 to move out of the support ring 31 through the inclined surface of the inclined groove 37. The shaft column 35 contacts and fixes the position of the bone drill shell 11. This state ensures that the bone drill always maintains an angle with the surgical site, improving the accuracy and stability of drilling.

[0070] Although embodiments of the present application have been shown and described, it is to be understood that various modifications, substitutions, replacements and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
