Description

Technical Field

[0001] This utility model relates to a tissue pad deburring device for ultrasonic surgical knives. Background Technology

[0002] An ultrasonic scalpel is a high-frequency electrosurgical device primarily used for procedures such as cutting biological tissues and closing blood vessels. An ultrasonic scalpel mainly consists of a handle, a generator, a vibrator, and a blade. The handle typically comprises a grip and a power cord. The generator is the core component, producing high-frequency sound waves. The vibrator receives these high-frequency sound waves and converts them into mechanical vibrations. The blade is very thin and rigid, made of titanium alloy or stainless steel, and is generally cylindrical.

[0003] The Importance of Deburring Ultrasonic Surgical Scalpels: 1. Improved Manufacturing Precision: During the manufacturing process of ultrasonic surgical scalpels, burrs may be generated on edges, corners, and other parts after cutting and other processes. The presence of these burrs affects the processing and assembly precision of the scalpel, so deburring is necessary to ensure its accuracy. 2. Guaranteed Performance: The presence of burrs may affect the performance of the ultrasonic surgical scalpel, such as cutting effect and vibration transmission. Deburring ensures that the scalpel can perform at its best during use. 3. Improved Appearance Quality: Deburring also improves the appearance quality of ultrasonic surgical scalpels, making them smoother and cleaner, meeting the aesthetic requirements of medical equipment.

[0004] Currently, the following methods can be used to deburr ultrasonic scalpels: 1. Ultrasonic deburring: This method utilizes the cavitation effect, direct impact effect, and micro-jets generated by ultrasound in a liquid medium to finely process burrs on the surface and within tiny pores of the ultrasonic scalpel. This method is relatively expensive. 2. Mechanical deburring: This includes manual or mechanical methods such as cutting, grinding, and using files or scrapers to remove burrs. This method is simple and easy to implement, but the processing precision is not high, and new burrs may be generated, requiring further processing. Summary of the Invention

[0009] The clamping assembly is horizontally rotatably mounted on the base via the lifting assembly. When the lifting assembly is in operation, the clamping assembly can drive the ultrasonic scalpel to move vertically downward and fit against the tissue pad.

[0010] The base is provided with a drive mechanism, which is connected to the roller and the clamping assembly respectively. When the drive mechanism is running, the roller and the clamping assembly will rotate simultaneously and in opposite directions, so that the tissue pad can perform deburring operation on the ultrasonic scalpel.

[0011] As a further embodiment of this utility model:

[0012] The clamping assembly includes a rotating rod located on one side of the tissue pad and horizontally rotatable, and a rotating base with one end fixedly connected to one end of the rotating rod. The rotating base has a first arc plate and a second arc plate symmetrically arranged inside.

[0013] The first arc-shaped plate is disposed inside the rotating base, and the second arc-shaped plate is slidably disposed inside the rotating base. A threaded post is provided on the rotating base with a threaded engagement. One end of the threaded post is rotatably connected to the side of the second arc-shaped plate away from the first arc-shaped plate, and the other end of the threaded post is provided with a knob.

[0014] As a further improvement of this utility model:

[0015] The inner sidewall of the rotating base is provided with a guide groove, and the second arc plate is provided with a guide block. The guide block is located inside the guide groove and slides with each other.

[0016] A vertical plate is vertically arranged on the base and on the other side of the tissue pad. A sleeve is vertically slidably arranged on the vertical plate.

A slider is provided on the side of the sleeve near the vertical plate. The slider is located in the T-shaped groove and slides with each other.

[0017] As a further improvement of this utility model:

[0018] The lifting assembly includes a sleeve and a sliding rod that slides with the sleeve. The sleeve is vertically mounted on the base, and one end of the sliding rod is rotatably connected to the rotating rod.

[0019] The outer wall of the sleeve is provided with a support base, a rotating shaft is vertically rotatably mounted on the support base, a fixing plate is horizontally mounted on the slide rod, and one end of the rotating shaft passes through the fixing plate;

[0020] The outer wall of the rotating shaft is provided with a spiral groove along its length, and the fixed plate is fitted with rolling balls, which are also fitted into the spiral groove.

[0021] As a further improvement of this utility model:

[0022] A bracket is provided on the base, and a worm gear is horizontally rotatably mounted on the bracket;

[0023] The other end of the rotating shaft is provided with a worm gear, the worm and the worm gear mesh with each other, and a handwheel is provided at one end of the worm.

[0030] Compared with the prior art, the beneficial effects of this utility model are:

[0031] The ultrasonic scalpel can be horizontally clamped by the clamping assembly, and then the lifting assembly moves the clamping assembly vertically downwards to fit against the tissue pad. The support frame supports the tissue pad. When the drive mechanism is activated, the roller and clamping assembly will rotate simultaneously in opposite directions. Due to the reverse rotation of the roller and clamping assembly, and the contact between the tissue pad and the ultrasonic scalpel, the rotating tissue pad will deburr the ultrasonic scalpel. Since the tissue pad is made of Teflon, it has good wear resistance and a low coefficient of friction, which not only avoids the low precision of traditional mechanical deburring methods and the need for cumbersome subsequent processing, but also reduces the cost of use.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Furthermore, the elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0045] Please see Figures 1-10 In this embodiment of the present invention, a tissue pad deburring device for an ultrasonic scalpel includes a base 1 and two rollers 2 that are horizontally rotatably mounted on the base 1. Tissue pads 3 are mounted on the outer walls of the two rollers 2. A support frame 4 is provided on the base 1. The top surface of the support frame 4 is in contact with the bottom surface of the upper layer of the tissue pad 3 to support the tissue pad 3.

[0046] Clamping components are provided on the base 1 and on both sides of the tissue pad 3. The clamping components are used to clamp the ultrasonic scalpel horizontally.

[0047] The clamping assembly is horizontally rotated on the base 1 via the lifting assembly. When the lifting assembly is in operation, the clamping assembly can drive the ultrasonic scalpel to move vertically downward and fit against the tissue pad 3.

[0048] The base 1 is provided with a driving mechanism, which is connected to the roller 2 and the clamping assembly respectively. When the driving mechanism is running, the roller 2 and the clamping assembly will rotate simultaneously and in opposite directions, so that the tissue pad 3 can perform deburring operation on the ultrasonic scalpel.

[0049] In this solution, the clamping assembly horizontally clamps the ultrasonic scalpel, and the lifting assembly moves the clamping assembly vertically downwards to fit against the tissue pad 3. The support frame 4 supports the tissue pad 3. When the drive mechanism is activated, the roller 2 and the clamping assembly rotate simultaneously in opposite directions. Due to the reverse rotation of the roller 2 and the clamping assembly, and the contact between the tissue pad 3 and the ultrasonic scalpel, the rotating tissue pad 3 deburrs the ultrasonic scalpel. Since the tissue pad 3 is made of Teflon, it has good wear resistance and a low coefficient of friction, which not only avoids the low precision of traditional mechanical deburring methods and the need for subsequent cumbersome processing, but also reduces the cost of use.

[0050] As a further embodiment of this utility model, the clamping assembly includes a rotating rod 5 located on one side of the tissue pad 3 and horizontally rotatable, and a rotating seat 6 with one end fixedly connected to one end of the rotating rod 5. The rotating seat 6 has a first arc plate 7 and a second arc plate 8 symmetrically arranged inside.

[0051] The first arc plate 7 is disposed inside the rotating base 6, and the second arc plate 8 is slidably disposed inside the rotating base 6. A threaded post 9 is threadedly disposed on the rotating base 6. One end of the threaded post 9 is rotatably connected to the side of the second arc plate 8 away from the first arc plate 7, and the other end of the threaded post 9 is provided with a knob 10.

[0052] In this embodiment, during specific use, one end of the ultrasonic scalpel is inserted into the rotating base 6 and positioned between the first arc plate 7 and the second arc plate 8. Since the threaded post 9 is threadedly engaged with the rotating base 6 and rotatably connected to the second arc plate 8, when the second arc plate 8 cannot rotate, the threaded post 9 is rotated by the knob 10. The threaded post 9 will then move the second arc plate 8 closer to the first arc plate 7, thereby clamping and fixing one end of the ultrasonic scalpel.

[0053] As a further embodiment of this utility model, the inner sidewall of the rotating seat 6 is provided with a guide groove 601, and the second arc plate 8 is provided with a guide block 801. The guide block 801 is located inside the guide groove 601 and slides with each other.

[0054] A vertical plate 11 is vertically arranged on the base 1 and on the other side of the tissue pad 3. A sleeve 12 is vertically slidably arranged on the vertical plate 11. The sleeve 12 and the rotating seat 6 are symmetrically arranged with respect to the tissue pad 3. A T-shaped groove 1101 is formed on one side wall of the vertical plate 11 along its length direction. A slider 1201 is provided on the side of the sleeve 12 near the vertical plate 11. The slider 1201 is located in the T-shaped groove 1101 and slides with each other.

[0055] In this embodiment, since the guide block 801 is located inside the guide groove 601 and slides with each other, the second arc plate 8 can only slide on the rotating seat 6 and cannot rotate.

[0056] The sleeve 12 can be changed to a matching size according to the size of the ultrasonic scalpel. When in use, the other end of the ultrasonic scalpel is inserted into the matching sleeve 12, and then the slider 1201 on the sleeve 12 is installed into the T-shaped groove 1101 on the vertical plate 11. Since the slider 1201 and the T-shaped groove 1101 are mutually sliding, the sleeve 12 can slide vertically on the vertical plate 11.

[0057] As a further embodiment of this utility model, the lifting assembly includes a sleeve 13 and a slide rod 14 that slides with the sleeve 13. The sleeve 13 is vertically mounted on the base 1, and one end of the slide rod 14 is rotatably connected to the rotating rod 5.

[0058] The outer wall of the sleeve 13 is provided with a support seat 15, and a rotating shaft 16 is vertically rotatably provided on the support seat 15. A fixing plate 17 is horizontally provided on the slide rod 14, and one end of the rotating shaft 16 passes through the fixing plate 17.

[0059] The outer wall of the rotating shaft 16 is provided with a spiral groove 1601 along its length direction, and the fixed plate 17 is fitted with a ball bearing 18, which is also fitted with the spiral groove 1601.

[0060] In this embodiment, since the fixed plate 17 has rolling balls 18 inside and the balls 18 are also rollingly fitted in the spiral groove 1601, when the rotating shaft 16 rotates and the fixed plate 17 cannot rotate, the fixed plate 17 will drive the slide bar 14 to move vertically downward.

[0061] Since the slide bar 14 and the sleeve 13 slide against each other, and one end of the slide bar 14 is rotatably connected to the rotating rod 5, the slide bar 14 will also drive the rotating rod 5 to move vertically downward during the vertical downward movement, so that the ultrasonic scalpel will come into contact with the tissue pad 3 and stop.

[0062] As a further embodiment of this utility model, a bracket 19 is provided on the base 1, and a worm gear 20 is horizontally rotatably mounted on the bracket 19.

[0063] The other end of the rotating shaft 16 is provided with a worm gear 21, the worm 20 and the worm gear 21 mesh with each other, and a handwheel 22 is provided at one end of the worm 20.

[0064] In this embodiment, since the worm 20 and the worm wheel 21 mesh with each other, when the worm 20 is rotated by the handwheel 22, the worm wheel 21 will rotate accordingly; and since the worm wheel 21 is mounted on the rotating shaft 16, the rotating shaft 16 will rotate accordingly.

[0065] Because the worm 20 and worm wheel 21 have self-locking characteristics, the worm wheel 21 will remain stationary and the shaft 16 will also remain stationary when no external force is applied to the worm 20.

[0066] As a further embodiment of this utility model, the driving mechanism includes a transmission rod 23, a first connecting rod 24 and a second connecting rod 25, one end of which are rotatably connected to the transmission rod 23 respectively. The other end of the first connecting rod 24 is rotatably connected to the roller shaft 2, and the other end of the second connecting rod 25 is rotatably connected to the rotating rod 5.

[0067] The transmission rod 23 is provided with a first gear 26, and one end of the rotating rod 5 is provided with a second gear 27. The first gear 26 and the second gear 27 mesh with each other.

[0068] In this embodiment, since the transmission rod 23 and the roller 2 are rotatably connected by the first connecting rod 24, and the transmission rod 23 and the rotating rod 5 are rotatably connected by the second connecting rod 25, the distance between the transmission rod 23 and the roller 2, and between the transmission rod 23 and the rotating rod 5 will always remain fixed when the rotating rod 5 moves vertically downward.

[0069] Since the first gear 26 fixed on the transmission rod 23 and the second gear 27 fixed on the rotating rod 5 mesh with each other, the rotating rod 5 will rotate in the opposite direction when the transmission rod 23 rotates.

[0070] As a further embodiment of this utility model, a first transmission wheel 28 is provided at the other end of the transmission rod 23, and a second transmission wheel 29 is provided on the roller shaft 2. The first transmission wheel 28 and the second transmission wheel 29 are connected by a belt 30.

[0071] A motor 31 is fixedly installed on the base 1, and the output end of the motor 31 is fixedly connected to one end of the roller 2.

[0072] In this embodiment, since the first transmission wheel 28 fixed on the transmission rod 23 and the second transmission wheel 29 fixed on the roller shaft 2 are connected by a belt 30, the transmission rod 23 will rotate synchronously when the roller shaft 2 rotates.

[0073] Since the output end of the motor 31 is fixedly connected to one end of the roller 2, and tissue pads 3 are installed on the outer walls of the two rollers 2, when the motor 31 is started, the rollers 2 will rotate and drive the tissue pads 3 to rotate.

[0074] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0075] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
