Description

Technical Field

[0001] This utility model relates to the field of dental products, and more specifically, to a multifunctional ultrasonic bone scalpel. Background Technology

[0002] Ultrasonic bone scalpels are effective only against bone tissue of a specific hardness, without damaging soft tissue or nerve tissue. The depth of the incision greatly affects the degree of trauma, hence the high frequency of use of ultrasonic bone scalpels in minimally invasive surgery. Minimally invasive surgery incisions are extremely small, and surgeons often judge the cutting depth by feel. Relying solely on touch and feel can easily lead to cutting too deeply or too large, requiring repeated checks of the cutting depth, resulting in low cutting efficiency. When cutting deep bone, water may not easily flow into the gap to cool the cutting tip, potentially causing the tip to overheat and burn soft tissue and nerves.

[0003] Currently, ultrasonic bone cutters on the market are quite mature, but there are almost none that can measure the depth of bone cutting while cutting bone.

[0004] The inventors discovered in their research that existing ultrasonic bone scalpels have at least the following drawbacks:

[0005] The cutting depth cannot be obtained during use, making operation inconvenient. Utility Model Content

[0006] The purpose of this invention includes, for example, providing a multifunctional ultrasonic bone scalpel that can not only cut bone tissue, but also obtain the cutting depth in real time during the cutting of bone tissue, thus offering diverse functions.

[0007] The embodiments of this utility model can be implemented as follows:

[0008] In a first aspect, this utility model provides a multifunctional ultrasonic bone scalpel, comprising:

[0009] The bone scalpel body and the laser ranging mechanism; the bone scalpel body includes a handle, an ultrasonic bone scalpel head and a connecting assembly; the ultrasonic bone scalpel head is mounted on the front end of the handle, and the connecting assembly is mounted on the outer peripheral surface of the handle;

[0010] The laser ranging mechanism includes a carrier and a laser ranging module, the laser ranging module being mounted on the carrier; the carrier is detachably connected to the handle via the connecting assembly.

[0011] In an optional embodiment, the connecting assembly includes two clamping plates, both of which are slidably connected to the handle portion around the handle portion in the circumferential direction, forming an adjustable clamping space between the two clamping plates, and the carrier is located within the clamping space; when the two clamping plates approach each other, the clamping space decreases and the two clamping plates cooperate to clamp the carrier.

[0012] In an optional embodiment, the carrier is provided with two positioning grooves;

[0013] Each of the clamping plates is provided with a positioning pin on its side. The positioning pins on the two clamping plates are used to engage with the two positioning grooves respectively to prevent the carrier from detaching from the handle.

[0014] In an optional embodiment, the connecting assembly further includes two elastic members, one end of which is connected to the two clamping plates respectively, and the other end of which is connected to the handle portion; each elastic member is used to make the corresponding clamping plate tend to slide toward the other clamping plate, so as to reduce the clamping space.

[0015] In an optional embodiment, the handle portion is provided with two guide cylinders arranged at intervals in its circumferential direction, each guide cylinder being provided with an arc-shaped guide channel extending in the circumferential direction of the handle portion;

[0016] Each of the clamps is provided with an arc-shaped guide post, which is slidably inserted into the guide cylinder; two elastic elements are respectively assembled in the two arc-shaped guide channels, each elastic element is simultaneously connected to the guide cylinder and the guide post, and each elastic element is used to make the corresponding guide post have a tendency to slide away from the guide cylinder.

[0017] In an optional embodiment, two anti-detachment heads are installed in each of the two guide cylinders, and locking screws are screwed onto the cylinder walls of both guide cylinders. Each anti-detachment head is fixed in the arc-shaped guide channel by the corresponding locking screw to restrict the anti-detachment head from sliding relative to the arc-shaped guide channel.

[0018] Each guide post is provided with an anti-detachment cap at its end, the anti-detachment cap being located within the arc-shaped guide channel. The anti-detachment head is used to contact the anti-detachment cap when the anti-detachment cap slides in a direction away from the arc-shaped guide channel, thereby preventing the guide post from detaching from the arc-shaped guide channel.

[0019] In an optional embodiment, the connecting assembly further includes an anti-accidental contact rod, which is slidably connected to the handle portion in the length direction of the handle portion. The anti-accidental contact rod is used to engage between the two clamping plates when the two clamping plates hold the carrier, so as to restrict the sides of the two clamping plates away from the carrier from getting closer to each other.

[0020] In an optional embodiment, the handle portion includes a housing, a first latching plate, and a second latching plate. The first latching plate and the second latching plate are both mounted on the housing and are spaced apart along the length of the housing. The carrier is simultaneously latched between the first latching plate and the second latching plate.

[0021] The connection component is mounted on the housing.

[0022] In an optional embodiment, the handle portion further includes a first torsion spring and a second torsion spring, both the first and second clamping plates being rotatably connected to the housing; the first torsion spring is connected to both the housing and the first clamping plate, for giving the first clamping plate a tendency to rotate toward the housing; the second torsion spring is connected to both the housing and the second clamping plate, for giving the second clamping plate a tendency to rotate toward the housing.

[0023] In an optional embodiment, the outer shell is provided with an assembly groove, and the carrier is snapped into the assembly groove.

[0024] The beneficial effects of this utility model embodiment include, for example:

[0025] In summary, the multifunctional ultrasonic bone scalpel provided in this embodiment has a laser ranging mechanism installed on the handle. Initially, the operator holds the handle, bringing the ultrasonic bone scalpel tip into contact with the bone tissue to be cut. At this time, the laser ranging mechanism acquires the initial distance between the ultrasonic bone scalpel tip and the bone tissue surface, and can transmit this initial distance information to a smart terminal, such as a computer, mobile phone, or tablet, via a wireless communication module such as Bluetooth. As the bone cutting operation continues, the ultrasonic bone scalpel tip cuts into the bone tissue, and the handle and laser ranging mechanism move closer to the bone tissue. The laser ranging mechanism acquires real-time distance information between itself and the bone tissue surface, and this real-time distance information can also be transmitted to the smart terminal. Since the real-time distance is less than the initial distance, the depth of bone tissue penetration can be obtained by the difference between the initial and real-time distances.

[0026] It should be understood that when the user holds the handle and operates the bone scalpel to cut bone tissue, the angle between the bone scalpel and the patient remains basically unchanged. In other words, the bone scalpel cuts into the bone tissue in basically the same posture. As a result, the laser ranging mechanism always obtains the distance between the same point on the bone tissue surface and the laser ranging mechanism, with small error. Attached Figure Description

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0039] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0040] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0041] In existing technologies, when using ultrasonic bone scalpels to cut bone tissue, the depth of the incision on the bone tissue is generally judged by the operator's experience, which has a large error. It also requires repeated stops to observe and judge, making the operation cumbersome and inefficient. There are also situations where the cutting operation cannot be carried out smoothly due to large errors in judgment.

[0042] In view of this, the designers have provided a multifunctional ultrasonic bone scalpel that can obtain the cutting depth in real time during the cutting of bone tissue without the need for repeated stops for observation and confirmation, thereby reducing the difficulty of operation, reducing the probability of misjudgment, improving work efficiency, and improving work safety.

[0043] Please refer to Figures 1-5 This embodiment provides a multifunctional ultrasonic bone scalpel, comprising:

[0044] The bone scalpel body 100 and the laser ranging mechanism 200; the bone scalpel body 100 includes a handle 110, an ultrasonic bone scalpel head 120 and a connecting assembly 130; the ultrasonic bone scalpel head 120 is mounted on the front end of the handle 110 and the connecting assembly 130 is mounted on the outer peripheral surface of the handle 110.

[0045] The laser ranging mechanism 200 includes a carrier 210 and a laser ranging module 220, with the laser ranging module 220 mounted on the carrier 210. The carrier 210 is detachably connected to the handle portion 110 via a connecting assembly 130.

[0046] As described above, the working principle of the multifunctional ultrasonic bone scalpel provided in this embodiment is as follows:

[0047] In the initial state, the operator holds the handle 110, bringing the ultrasonic bone scalpel head 120 into contact with the bone tissue to be cut. The laser ranging mechanism 200 is activated, acquiring the initial distance between the ultrasonic bone scalpel head 120 and the bone tissue surface. This initial distance parameter information can be transmitted to a smart terminal via a wireless communication module such as Bluetooth. The smart terminal can store and process the parameter information. As the bone cutting operation continues, the ultrasonic bone scalpel head 120 cuts into the bone tissue. The handle 110 and the laser ranging mechanism 200 move closer to the bone tissue. The laser ranging mechanism 200 acquires the real-time distance parameter information between itself and the bone tissue surface, and this real-time distance information is also transmitted to the smart terminal. The real-time distance is less than the initial distance; the difference between the initial distance and the current real-time distance allows the operator to determine the depth of the bone scalpel cutting into the bone tissue at the current stage.

[0048] It should be understood that when the user holds the handle 110 and operates the bone scalpel to cut bone tissue, the angle between the bone scalpel and the patient will not change much. That is, the bone scalpel cuts into the bone tissue in basically the same posture. In this way, the laser ranging mechanism 200 always obtains the distance between the same point on the bone tissue surface and the laser ranging mechanism 200, with small error.

[0049] Furthermore, after the initial distance and real-time distance are transmitted to the smart terminal, the difference can be calculated directly by the smart terminal and announced via the voice module. Alternatively, the parameter information can be displayed on the smart terminal's screen for easy observation by the operator.

[0050] Furthermore, since the laser ranging mechanism 200 is detachably connected to the bone blade body 100, it can be removed from the bone blade body 100 when ranging is not required, thereby reducing the weight of the bone blade body 100 and making it easier to use. At the same time, with the laser ranging mechanism 200 removed, the overall size of the bone blade body 100 is smaller, making it less likely to obstruct the user's view.

[0051] The following embodiments illustrate the details of the multifunctional ultrasonic bone scalpel of this application by way of example.

[0052] Please refer to Figures 1-5In this embodiment, optionally, the multifunctional ultrasonic bone scalpel includes a bone scalpel body 100 and a laser ranging mechanism 200. The laser ranging mechanism 200 is detachably connected to the bone scalpel body 100.

[0053] Optionally, the bone scalpel body 100 includes a handle portion 110, an ultrasonic bone scalpel head 120, and a connecting assembly 130. The ultrasonic bone scalpel head 120 is mounted on the front end of the handle portion 110, and the connecting assembly 130 is mounted on the outer peripheral surface of the handle portion 110. The connecting assembly 130 can detachably position the laser ranging mechanism 200 on the handle portion 110.

[0054] The handle 110 includes a housing 111, a first retaining plate 112, a second retaining plate 113, a first rotating shaft 114, a second rotating shaft 115, a first torsion spring, a second torsion spring, and two guide cylinders 116.

[0055] Optionally, the outer casing 111 can be configured as a split casing structure. For example, the outer casing 111 includes two half-shells that are fastened together and fixed by screws or clips. After the two half-shells are fixed, they cooperate to define a receiving cavity, which can accommodate components such as batteries, circuit boards, and controllers.

[0056] In addition, the outer peripheral surface of the housing 111 is provided with a mounting groove 1111, which can accommodate the laser ranging mechanism 200.

[0057] Please refer to Figures 1-5 Optionally, the first clamping plate 112 is rotatably connected to the outer shell 111 via a first rotating shaft 114. A first torsion spring is sleeved on the outside of the first rotating shaft 114 and is connected to both the first clamping plate 112 and the outer shell 111. The first torsion spring is used to give the first clamping plate 112 a tendency to rotate closer to the outer shell 111. The second clamping plate 113 is rotatably connected to the outer shell 111 via a second rotating shaft 115. A second torsion spring is sleeved on the outside of the second rotating shaft 115 and is connected to both the second clamping plate 113 and the outer shell 111. The second torsion spring is used to give the second clamping plate 113 a tendency to rotate closer to the outer shell 111. The first rotating shaft 114 and the second rotating shaft 115 are arranged parallel to each other along the length of the outer shell 111, and are distributed on both sides of the mounting groove 1111 along the length of the outer shell 111. In the initial state, both the first clamping plate 112 and the second clamping plate 113 are attached to the outer surface of the outer shell 111 under the action of their respective torsion springs.

[0058] Furthermore, the first card plate 112 is located on the side of the second card plate 113 closer to the front end of the outer shell 111, that is, the first card plate 112 is closer to the ultrasonic bone scalpel head 120 than the second card plate 113.

[0059] Optionally, each guide cylinder 116 includes a cylinder body 1161, an anti-slip head 1162, and a locking screw 1163. The cylinder body 1161 can be an arc-shaped cylinder, and the cross-section of the cylinder body 1161 is annular, with the cross-section being a plane perpendicular to the extending direction of the cylinder body 1161. Both cylinder bodies 1161 are fixed to the outer circumferential surface of the outer casing 111, and the two cylinder bodies 1161 are spaced apart in the circumferential direction of the outer casing 111, extending on the same circumference. Each cylinder body 1161 has a first end and a second end opposite to each other in its extending direction, with the two first ends spaced apart and the two second ends spaced apart. The first end is closed, and the second end is open. A threaded fixing hole is provided on the cylinder wall of the cylinder body 1161 near the second end. The locking screw 1163 is screwed into the threaded fixing hole. The anti-slip head 1162 is designed as a ring structure. It is inserted into the cylinder 1161 from the second end and fixed in place by a locking screw 1163, preventing it from sliding relative to the cylinder 1161. Furthermore, for ease of assembly, the inner wall of the cylinder 1161 has an anti-rotation plane, and the outer circumferential surface of the anti-slip head 1162 has a positioning plane with a through hole coaxial with the threaded fixing hole. During assembly, the positioning plane and the anti-rotation plane fit together, providing a good anti-rotation effect. Simultaneously, the cooperation between the positioning plane and the anti-rotation plane guides the anti-slip head 1162 into the cylinder 1161 in a predetermined posture, allowing the through hole to quickly align with the threaded fixing hole, facilitating the fixing of the anti-slip head 1162 with the locking screw 1163.

[0060] It should be understood that the ultrasonic bone scalpel head 120 provided in this embodiment can refer to existing known structures. It is installed at the front end of the handle 110 and can use ultrasonic energy to perform actions such as cutting bone tissue. In order to avoid repetition and redundancy, its specific structure and working principle will not be described in detail in this embodiment.

[0061] Optionally, the connecting assembly 130 includes two clamping plates 131, two positioning pins 132, two elastic elements 133, and two guide pins 134. Each clamping plate 131 can be an arc-shaped plate, and each clamping plate 131 has a first side and a second side in its bending direction. The two positioning pins 132 are respectively connected to the second side of the two clamping plates 131, and the two guide pins 134 are respectively connected to the first side of the two clamping plates 131. Each guide pin 134 has an anti-detachment cap 135 at its end away from the clamping plate 131. The anti-detachment cap 135 can be screwed into the guide pin 134, thus protruding radially outward from the outer circumferential surface of the guide pin 134.

[0062] During assembly, first remove the two anti-slip caps 135, then attach the two anti-slip heads 1162 to the outside of the two guide posts 134 respectively, and then screw the two anti-slip caps 135 to the outside of the guide posts 134. Next, place the two elastic elements 133 from the second end of the corresponding cylinders 1161 into the two cylinders 1161 respectively, and then insert the two guide posts 134 from the second end of the corresponding cylinders 1161 into the two cylinders 1161 respectively. During this process, the guide posts 134 or the anti-slip caps 135 compress the elastic elements 133, causing the elastic elements 133 to shorten and have the elastic force to recover their deformation. Furthermore, the anti-slip heads 1162 enter the cylinders 1161 and are fixed inside the cylinders 1161 using locking screws 1163. Thus, by using the cooperation of the anti-slip heads 1162 and anti-slip caps 135, the guide posts 134 can be prevented from slipping out from the second end of the cylinders 1161. In the initial state, the elastic element 133 has the elastic force to restore deformation, so that the two anti-slip caps 135 are basically in contact with the two anti-slip heads 1162, the distance between the two positioning pins 132 is minimized, and the width of the clamping space formed between the two positioning pins 132 is minimized.

[0063] It should be understood that the elastic element 133 can be a spring, etc.

[0064] Furthermore, each clamping plate 131 has an outwardly convex tab 136 on its first side. The tabs 136 on the two clamping plates 131 are arranged at intervals. When in use, two fingers can be used to apply force to the two tabs 136, thereby causing the two tabs 136 to move closer to each other. This means that the first sides of the two clamping plates 131 move closer together, while the corresponding two second sides move away from each other, increasing the size of the clamping space.

[0065] In other embodiments, optionally, the connecting assembly 130 further includes an anti-accidental contact rod 137, which is slidably connected to the housing 111 along its length. The anti-accidental contact rod 137 is used to engage between the two clamping plates 131 when the laser ranging mechanism 200 is clamped, thereby limiting the sides of the two clamping plates 131 away from the carrier 210 from approaching each other. Specifically, when the laser ranging mechanism 200 is clamped by the two clamping plates 131, if it is necessary to release the laser ranging mechanism 200, the first sides of the two clamping plates 131 must first be brought closer together and the second sides moved away to increase the clamping space. When the laser ranging mechanism 200 is clamped by the two clamping plates 131, in order to prevent the laser ranging mechanism 200 from automatically falling off due to misoperation, the anti-misoperation rod 137 is slid between the protrusions 136 of the two clamping plates 131. This can limit the two protrusions 136 from getting close to each other, that is, limit the two first sides from getting close to each other. Correspondingly, the two second sides will not move away from each other, so the laser ranging mechanism 200 will not be released, and the use is safe.

[0066] It should be understood that the anti-accidental contact rod 137 can be an arc-shaped rod that makes close contact with the outer casing 111 and slides stably.

[0067] Optionally, the laser ranging mechanism 200 includes a carrier 210 and a laser ranging module 220, with the laser ranging module 220 mounted on the carrier 210. The carrier 210 is detachably connected to the handle portion 110 via a connecting assembly 130. Specifically, the carrier 210 is clamped between a first clamping plate 112 and a second clamping plate 113, and the positioning pins 132 on the two clamping plates 131 engage with the carrier 210, thereby holding the carrier 210 tightly and achieving a fixed connection between the carrier 210 and the outer casing 111.

[0068] Optionally, the carrier 210 is configured as a housing, and the laser ranging module 220 is installed in the housing. The housing is provided with a light-transmitting window for the laser ranging module 220 to emit and receive the laser beam. The carrier 210 is provided with a positioning protrusion 212 and two positioning grooves 211.

[0069] During assembly, the first clamping plate 112 and the second clamping plate 113 are rotated open, and force is applied to the two protrusions 136 to increase the clamping space. Then, the positioning protrusions 212 of the carrier 210 are inserted into the assembly grooves 1111. The two positioning grooves 211 on the carrier 210 are distributed circumferentially on the outer shell 111. The first clamping plate 112 and the second clamping plate 113 respectively contact the two sides of the carrier 210 along the length of the outer shell 111. The positioning pins 132 on the two clamping plates 131 respectively engage with the two positioning grooves 211 on the carrier 210. Under the action of the two elastic elements 133, the two positioning pins 132 clamp the carrier 210. Then, the anti-misoperation rod 137 is slid between the two protrusions 136 to limit the increase of the clamping space. In this way, the laser ranging mechanism 200 is stably clamped.

[0070] It should be understood that the laser ranging module 220 is a known existing structure, and the distance can be obtained by calculating the round-trip time of the laser. For example, the laser ranging module 220 emits a laser pulse to the surface of bone tissue and receives the beam reflected back from the surface of bone tissue. The distance is calculated using the speed of light, the emission time, and the reception time. The reference formula is: d = ct / 2, where d is the distance, c is the speed of light, and t is the round-trip time of the laser pulse.

[0071] It should be understood that the laser ranging module 220 can communicate and connect with smart terminals via Bluetooth or other means, which is beneficial for data storage and processing.

[0072] In addition, the laser ranging mechanism 200 can be equipped with its own power supply, which is installed inside the carrier and provides power to electrical components such as the laser ranging module 220.

[0073] The multifunctional ultrasonic bone scalpel provided in this embodiment can obtain the cutting depth during bone tissue cutting and has diverse functions.

[0074] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
