Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a therapeutic instrument host and a medical device. Background Technology

[0002] Currently, in clinical applications of therapeutic devices, a handpiece holder is typically installed on the main unit. When not in use, the handpiece is inserted into the holder, and the handpiece and holder are usually fixed and limited by a localized interference structure. This installation method results in unstable positioning of the handpiece within the holder, affecting the user experience. Furthermore, because the bottom of the handpiece holder is open, dust can easily enter through the bottom and accumulate on the surface of the optical components at the handpiece head, interfering with laser output quality and potentially shortening the device's lifespan. Utility Model Content

[0003] The main purpose of this utility model is to propose a therapeutic instrument host and medical device, which aims to provide convenient insertion and removal of the handpiece and stable assembly, while also meeting the requirements for sealed handpiece assembly.

[0004] To achieve the above objectives, this utility model proposes a therapeutic instrument host, the therapeutic instrument host comprising: The treatment device body has an inner cavity and an assembly slot, the assembly slot is connected to the inner cavity, and the assembly slot is used for inserting and placing hand tools; The clamping mechanism includes a trigger key, a transmission assembly, and multiple clamping components. The trigger key is installed on the outer wall of the therapeutic instrument body, the transmission assembly is installed in the inner cavity, one end of the trigger key extends into the inner cavity and is connected to one end of the transmission assembly, and the other end of the transmission assembly is connected to multiple clamping components. The trigger key triggers the transmission assembly to drive each of the clamping members into the assembly slot, so that the multiple clamping members clamp the hand located in the assembly slot.

[0005] In one embodiment, the transmission assembly includes: A rack, which is connected to the trigger key; A gear disk, the outer peripheral wall of which meshes with the rack; the gear disk is provided with a plurality of eccentric grooves, each of which is eccentric and inclined relative to the center of the gear disk; one end of each clamping member is slidably connected to one of the eccentric grooves, and the other end extends movably into the assembly groove.

[0006] In one embodiment, the treatment device body is further provided with a plurality of through holes communicating with the assembly groove, and the inner cavity has a plurality of mounting positions, each of the mounting positions communicating with a through hole; Each of the clamping elements is mounted in one of the mounting positions; One end of each clamping member is slidably connected to an eccentric groove, and the other end is movably inserted through a through hole, so that multiple clamping members can simultaneously extend into the assembly groove to clamp the hand tool.

[0007] In one embodiment, the clamping member includes: A push rod, wherein the push rod is installed at the mounting position and one end of the push rod is movably inserted through the through hole; A slider, which is connected to the body of the push rod and slidably connected within the eccentric groove; and A reset elastic element is sleeved on the push rod, and the two ends of the reset elastic element abut against the inner wall of the mounting position and the side of the slider facing away from the through hole, respectively. The slider slides on the edge of the eccentric groove away from the gear disk to drive the push rod out of the through hole so that the push rod contacts the hand tool.

[0008] In one embodiment, a rolling pulley is provided at the end of the slider away from the push rod, and the rolling pulley is slidably connected in the eccentric groove.

[0009] In one embodiment, the clamping member further includes a flexible portion at one end of the push rod passing through the through hole, the flexible portion being used to contact the hand tool.

[0010] In one embodiment, the end of the push rod away from the reset elastic member is provided with a mounting hole, and one end of the flexible part is movably connected to the mounting hole.

[0011] In one embodiment, the flexible part is a silicone retaining ring.

[0012] In one embodiment, the clamping mechanism further includes a first limiting part and a second limiting part disposed in the inner cavity, the first limiting part and the second limiting part being located at both ends of the rack and being spaced apart; the first limiting part and the second limiting part are used to limit the movement range of the rack.

[0013] This utility model also proposes a medical device, including a hand and the main unit of the therapeutic instrument.

[0014] The main body of this therapeutic instrument comprises a therapeutic instrument body, a clamping mechanism, and a handpiece. The therapeutic instrument body has an internal cavity for accommodating the transmission components, an assembly slot for mounting the handpiece, and a through hole connecting the internal cavity and the assembly slot. The clamping mechanism includes an external trigger key, a transmission component installed in the internal cavity, and multiple clamping parts. When treatment is not required, the handpiece, as the treatment terminal component, is directly inserted into the assembly slot of the main body. Through the synergistic action of the clamping mechanism and the assembly slot, the handpiece can be directly inserted into the assembly slot without complex alignment or external force assistance, thus simplifying the insertion and removal operation and improving ease of use. Simultaneously, the trigger key drives the transmission components, causing the clamping parts to extend from the through hole into the assembly slot and clamp the handpiece. The clamping force generated by the mechanical transmission ensures that the handpiece is fixed to the main body, preventing loosening or slippage, thereby meeting the requirements for stable assembly. Meanwhile, the clamping parts of the gripper can extend and retract relative to the assembly slot, so that the gripper will not face the situation of unlocking failure. Therefore, the treatment device body does not need to be designed with an unlocking space that connects to the outside world, so that the gripper can be sealed and assembled on the treatment device body. This design not only ensures a reliable connection between the gripper and the treatment device body through a controllable clamping mechanism, but also achieves sealed assembly through an adjustable clamping mechanism.

[0022] In practical applications of therapeutic device main units, the main unit is generally assembled with the handpiece using a fixing method that involves partial interference. If the assembly slot has an open bottom design, the handpiece is continuously exposed to the external environment, allowing dust from the external environment to continuously enter the lens of the handpiece through the bottom opening. The accumulation of dust on the surface of the handpiece lens will change the refraction path of the laser, thereby interfering with the energy distribution characteristics of the optical system. If the assembly slot has a closed design, after the handpiece is inserted into the assembly slot, the interference between the sealed assembly slot wall and the handpiece makes it difficult to remove the handpiece when it needs to be disassembled.

[0023] For this, please refer to Figures 1 to 4 This application proposes a therapeutic device main unit, including a therapeutic device body 10, a clamping mechanism 20, and a handpiece 30. The therapeutic device body 10 has an inner cavity 10a and an assembly groove 10b, with the assembly groove 10b communicating with the inner cavity 10a. The clamping mechanism 20 includes a trigger key 21, a transmission component 22, and at least two clamping members 23. The trigger key 21 is installed on the outer wall of the therapeutic device body 10, and the transmission component 22 is installed in the inner cavity 10a. One end of the trigger key 21 extends into the inner cavity 10a and is connected to one end of the transmission component 22. The other end of the transmission component 22 is connected to multiple clamping members 23. One end of the handpiece 30 is inserted into the assembly groove 10b. The trigger key 21 triggers the transmission component 22 to drive each clamping member 23 to extend into the assembly groove 10b, so that multiple clamping members 23 clamp the handpiece 30 located in the assembly groove 10b.

[0024] This embodiment relates to a therapeutic device main unit. The therapeutic device body 10 has an inner cavity 10a and an assembly slot 10b. The assembly slot 10b communicates with the inner cavity 10a, providing a spatial basis for the operation of the clamping mechanism 20. The assembly slot 10b is used for inserting and placing the hand tool 30. The clamping mechanism 20 includes a trigger key 21, a transmission component 22, and multiple clamping components 23. The trigger key 21 is installed on the outer wall of the therapeutic device body 10 for easy user operation and triggering. The transmission component 22 is installed in the inner cavity 10a for transmitting and converting motion.

[0025] In practical applications, the transmission component 22 refers to the mechanism that converts the linear motion of the trigger key 21 into the radial motion of multiple clamping parts 23. It can be implemented by a linkage mechanism, a cam mechanism or a worm gear mechanism. For example, the linear motion can be converted into radial extension and retraction by the swing of the linkage. Its main purpose is to realize the transmission of triggering action and the conversion of motion form.

[0026] Furthermore, the clamping component 23 refers to the part used to clamp the hand tool 30. It can be implemented using elastic clips, magnetic adsorption components, or mechanical claws. For example, the hand tool can be clamped by the elastic deformation of a spring. Its main purpose is to fix the hand tool 30 and fill the gap between the assembly groove 10b and the hand tool 30. Thus, when the trigger key 21 is triggered, the transmission component 22 simultaneously drives multiple clamping components 23 to extend into the assembly groove 10b, so that multiple clamping components 23 clamp the hand tool 30 located in the assembly groove 10b, thereby fixing the hand tool 30. The assembly groove 10b only has a hole for one end of the clamping component 23 to extend out. After the hand tool 30 is inserted into the assembly groove 10b, the end of the clamping component 23 away from the transmission component 22 extends into the assembly groove 10b through this hole and abuts against the hand tool 30, so that the hand tool, the clamping component 23, and the assembly groove 10b form a sealed cavity, thereby effectively preventing dust from entering the head of the hand tool 30.

[0027] Specifically, this design utilizes the linkage mechanism of the clamping mechanism 20. After the hand tool 30 is inserted into the assembly slot 10b, the trigger key 21 triggers the transmission component 22 to drive the clamping component 23 to move synchronously. This not only ensures the stability of the hand tool 30 during operation but also effectively seals the opening area of ​​the assembly slot 10b, meeting the sealing requirements of the hand tool 30 during assembly.

[0028] In one embodiment, the treatment device body 10 has an inner cavity 10a and an assembly groove 10b. The assembly groove 10b communicates with the inner cavity 10a, providing a concealed space for the operation of the clamping mechanism 20 and avoiding external interference. The clamping mechanism 20 includes a trigger key 21, a transmission assembly 22, and multiple clamping elements 23. The trigger key 21 is installed on the outer wall of the treatment device body 10 for easy and intuitive triggering by the user. The transmission assembly 22 is installed in the inner cavity 10a, converting the linear motion of the trigger key 21 into the radial motion of the clamping elements 23. One end of the trigger key 21 extends into the inner cavity 10a and connects to the transmission assembly 22, ensuring the accuracy of motion transmission and immediate response. The multiple clamping elements 23 are connected to the transmission assembly 22 to achieve coordinated and synchronous operation of the multiple clamping elements 23.

[0029] When the trigger key 21 is activated, the trigger key 21 drives the transmission component 22 to simultaneously extend multiple clamping members 23 into the assembly groove 10b, so that the multiple clamping members 23 simultaneously clamp the hand tool 30 located therein. This mechanism not only reliably fixes the hand tool 30 to eliminate positioning wobbling, but also fills the gap between the assembly groove 10b and the hand tool 30 by extending the clamping members 23, forming a physical barrier.

[0030] Please see Figures 3 to 5This application further proposes that the transmission assembly 22 includes a rack 221 and a gear disk 222. The rack 221 is connected to the trigger key 21. The outer peripheral wall of the gear disk 222 is meshed with the rack 221. The gear disk 222 is provided with a plurality of eccentric grooves 222a, each eccentric groove 222a being eccentric and inclined relative to the center of the gear disk 222. One end of the clamping member 23 is slidably connected to the eccentric groove 222a, and the other end extends movably into the assembly groove 10b.

[0031] Among them, rack 221 refers to the core transmission component that realizes linear motion transmission. It can be implemented by metal straight rack or engineering plastic molded rack structure. The purpose is to ensure that the pressing action of trigger key 21 is stably converted into precise linear displacement. Gear disk 222 can be understood as motion form conversion mechanism. It can be implemented by standard module gear or non-circular gear structure. The purpose is to efficiently and continuously convert the linear motion of rack 221 into rotational motion. Eccentric groove 222a specifically refers to the geometric constraint structure that guides the motion trajectory of clamping member 23. It can be designed as a spiral curve groove or compound curved surface groove. The purpose is to generate a composite displacement path of radial and axial directions to avoid uneven clamping caused by unidirectional motion. Clamping member 23 can be understood as the terminal component that performs the clamping function. It can be implemented by rigid metal rod or elastic composite material rod structure. The purpose is to convert motion into a uniform force on hand tool 30 in assembly groove 10b.

[0032] Specifically, when the trigger key 21 is pressed, it drives the rack 221 to move in a straight line. The meshing connection between the rack 221 and the outer peripheral wall of the gear disk 222 converts the linear motion into the rotational motion of the gear disk 222. During the rotation of the gear disk 222, the eccentric groove 222a forms a specific spatial trajectory due to its eccentric and inclined setting. This trajectory guides the clamping member 23 slidably connected therein to generate a coordinated radial and axial composite displacement. Since all clamping members 23 are connected to each eccentric groove 222a of the same gear disk 222, the movement of each clamping member 23 is controlled synchronously, thereby ensuring that they simultaneously extend into the assembly groove 10b to apply a uniformly distributed clamping force to the hand tool 30 located therein, thereby achieving a stable fixation of the hand tool 30 and an effective closure of the opening of the assembly groove 10b.

[0033] As a preferred embodiment, the solution of this application is specifically implemented as follows: the gear disk 222 can be specifically a ring gear structure, and its outer peripheral wall is provided with an involute tooth shape that matches the rack 221; the eccentric groove 222a can be designed as a curved groove offset from the center of the gear disk 222 outward, and the inclination angle of the eccentric groove 222a changes continuously along the circumferential direction; the clamping member 23 can be specifically a slender rod made of stainless steel, one end of which is provided with a spherical sliding head that cooperates with the eccentric groove 222a, and the other end extends into the assembly groove 10b; when the trigger key 21 is pressed, the rack 221 pushes the gear disk 222 to rotate, and the eccentric groove 222a guides each clamping member 23 to move outward synchronously, uniformly clamping the outer peripheral wall of the hand tool 30 and forming an annular sealing interface.

[0034] Through the above technical solution, multiple clamping components 23 can move synchronously and coordinately, and evenly distribute the clamping force, effectively solving the problem of unstable positioning of the hand tool 30. At the same time, after the clamping component 23 extends into the assembly groove 10b, it forms a tight annular sealing structure, which significantly improves the sealing performance of the assembly groove 10b, preventing dust from entering through the bottom of the assembly groove 10b and accumulating on the surface of the optical element at the head of the hand tool 30, thereby ensuring the quality of laser output and the service life of the equipment.

[0035] In another embodiment, the trigger key 21 can be configured as a spring-reset push-button switch, the transmission assembly 22 can be specifically a four-bar linkage consisting of a connecting rod and a rotating shaft, and the clamping member 23 can be specifically two elastic arc-shaped metal plates. When the push-button switch is pressed, the four-bar linkage drives the arc-shaped metal plates to move synchronously towards the center of the assembly slot 10b, clamping the handpiece 30. Thus, the handpiece 30 remains stable within the assembly slot 10b, preventing shaking during operation; simultaneously, the insertion of the clamping member 23 effectively seals the opening of the assembly slot 10b, preventing external dust from entering, thereby protecting the optical components at the head of the handpiece 30, ensuring laser output quality, and improving the stability of equipment operation.

[0036] Please see Figures 4 to 6 This application further proposes that the main body of the treatment device is provided with a plurality of through holes 10c communicating with the assembly groove 10b, the inner cavity 10a has a plurality of mounting positions, each mounting position communicating with a through hole 10c; each clamping member 23 is mounted in a mounting position; one end of each clamping member 23 is slidably connected to an eccentric groove 222a, and the other end is movably inserted through a through hole 10c, so that the plurality of clamping members 23 simultaneously extend into the assembly groove 10b to clamp the hand tool 30; And / or, multiple clamping parts 23 are arranged at intervals around the assembly groove 10b.

[0037] Among them, multiple perforations 10c refer to multiple through-hole structures set on the main body of the treatment device, which can be circular, elliptical, or irregularly shaped holes, and are intended to provide a guide channel for the clamping component 23 to enter the assembly groove 10b; multiple mounting positions refer to multiple fixed positions set in the inner cavity, which can be implemented using grooves or bracket structures, and are intended to ensure the stability of the movement trajectory of the clamping component 23; the number of eccentric grooves 222a and clamping components 23 is multiple, which means that multiple sets of eccentric grooves 222a and clamping components 23 are set, and multiple numbers can be used to distribute the clamping force and enhance synchronization; each clamping component One end of clamping member 23 is slidably connected to the eccentric groove 222a, and the other end is movably inserted through the through hole 10c. This means that clamping member 23 is slidably engaged in the eccentric groove 222a and extends to the assembly groove 10b. This can be achieved by using a sliding block and groove engagement structure or a linkage mechanism. The purpose is to efficiently convert rotational motion into linear displacement. Multiple clamping members 23 are arranged at intervals around the assembly groove 10b. This means that clamping members 23 are evenly distributed circumferentially along the assembly groove 10b. This can be achieved by using equal or unequal intervals. The purpose is to form a continuous clamping force distribution and sealing barrier, thereby improving the clamping uniformity of the hand tool 30.

[0038] Specifically, the solution of this application connects multiple perforations 10c on the main body of the treatment device to the assembly groove 10b, allowing the clamping member 23 to extend into the assembly groove 10b area from different directions, thus avoiding force concentration during single-point or double-point clamping; multiple mounting positions of the inner cavity 10a correspond one-to-one with the perforations 10c, ensuring that the clamping member 23 maintains a consistent trajectory during movement and preventing synchronization failure; there are multiple eccentric grooves 222a and clamping members 23, with each clamping member 23 installed in an independent mounting position. When the gear disk 222 rotates, the multi-groove structure of the eccentric groove 222a... All clamping components 23 are driven to slide synchronously, converting rotational motion into synchronous linear displacement. One end of the clamping component 23 slides in the eccentric groove 222a, and the other end passes through the through hole 10c. The inclined eccentricity of the eccentric groove 222a generates a gentle radial displacement. Combined with the guiding effect of the through hole 10c, the clamping action is ensured to be smooth and without jamming. Multiple clamping components 23 extend into the assembly groove 10b synchronously to clamp the hand tool 30, forming a uniform pressure distribution to suppress hand tool shaking. Multiple clamping components 23 are arranged at intervals around the assembly groove 10b to eliminate local gaps and build a continuous sealing barrier to prevent dust intrusion.

[0039] In one specific implementation, the therapeutic instrument body 10 of this application has multiple perforations 10c evenly distributed around the assembly groove 10b, and the inner cavity 10a has multiple mounting positions corresponding to them; there are multiple eccentric grooves 222a and clamping members 23, each clamping member 23 is slidably connected to the eccentric groove 222a through a slider structure and passes through the perforations 10c; the clamping members 23 are made of elastic material and are arranged at equal intervals around the assembly groove 10b.

[0040] Through the above solution, the positioning stability of the hand tool 30 of this application is significantly improved, the clamping force is evenly distributed, and the hand tool 30 is effectively prevented from slight shaking during operation; at the same time, multiple clamping points form a continuous seal, preventing external dust from entering the optical element area of ​​the head of the hand tool 30 through the bottom of the assembly groove 10b, ensuring the quality of laser output and extending the service life of the equipment.

[0041] Please see Figures 4 to 6 In this regard, the present application further proposes that the clamping member 23 includes a push rod 231, a slider 232, and a reset elastic member 233. The push rod 231 is installed in the mounting position, and one end of the push rod 231 is movably inserted through the through hole 10c. The slider 232 is connected to the rod body of the push rod 231 and is slidably connected in the eccentric groove 222a. The reset elastic member 233 is sleeved on the push rod 231, and the two ends of the reset elastic member 233 respectively abut against the inner wall of the mounting position and the side of the slider 232 facing away from the through hole 10c. The slider 232 slides in the eccentric groove 222a towards the edge away from the gear disk 222 to drive the push rod 231 to extend out of the through hole 10c so that the push rod 231 contacts the hand tool 30.

[0042] In practical applications, push rod 231 is the core component for realizing linear displacement transmission. It can be implemented using a metal rod or an engineering plastic rod. Its purpose is to directly contact the outer peripheral wall of the handpiece 30 through axial extension and contraction, avoiding assembly deviations caused by rigid collisions. Slider 232 can be understood as a key component of the motion conversion mechanism. It can be implemented using a sliding block or a guide block. Its purpose is to stably convert the eccentric rotational motion of the gear disk 222 into the linear motion of push rod 231, ensuring the continuity of the motion trajectory. Reset elastic element 233 is an elastic element that provides an automatic reset function. It can be implemented using a helical spring or an elastic rubber sleeve. Its purpose is to efficiently generate a reset force after the trigger key 21 is released, ensuring that the clamping part 23 retracts into the through hole 10c in a timely manner.

[0043] Specifically, when the trigger key 21 is pressed, it drives the rack 221 to move linearly, thereby driving the gear disk 222 to rotate. The eccentric groove 222a of the gear disk 222, as it rotates, pushes the slider 232 to slide along the eccentric groove 222a. Since the slider 232 is fixedly connected to the push rod 231, it drives the push rod 231 to extend out of the through hole 10c and contact the outer peripheral wall of the handpiece 30 to achieve clamping. When the trigger key 21 is released, the elastic force of the reset elastic element 233 acts on the side of the slider 232 facing away from the through hole 10c, pushing the slider 232 to slide in the opposite direction along the eccentric groove 222a back to its initial position, causing the push rod 231 to retract into the through hole 10c and complete automatic reset. This bidirectional motion closed-loop design, through the synergistic effect of the geometric characteristics of the eccentric groove 222a and the elastic force of the reset elastic element 233, ensures reliable switching between clamping and releasing actions. Simultaneously, the through hole 10c forms an effective seal when the push rod 231 is retracted, preventing external dust from entering.

[0044] In a preferred embodiment, the push rod 231 of this application can be a cylindrical rod made of stainless steel, the slider 232 can be a sliding block made of brass, and the reset elastic element 233 can be a helical compression spring. When the hand tool 30 is inserted into the assembly slot 10b, the operator presses the trigger key 21, the gear disk 222 rotates and drives the slider 232 to move along the eccentric groove 222a, and the push rod 231 extends out of the through hole 10c to contact the outer peripheral wall of the hand tool 30 to achieve a stable clamping. After releasing the trigger key 21, the reset elastic element 233 pushes the slider 232 back, and the push rod 231 retracts into the through hole 10c, making it easy for the hand tool 30 to be pulled out quickly.

[0045] In some embodiments, when the trigger key 21 is not triggered, the reset elastic element 233 remains in a normal state, allowing the push rod 231 to extend into the assembly groove 10b; when the trigger key 21 is triggered, the reset elastic element 233 is compressed, and the push rod 231 retracts into the interior. At this time, the hand tool can be inserted into the assembly groove 10b, and then the trigger key 21 is released. The reset elastic element 233 releases its elastic potential energy, pushing the push rod 231 to extend into the assembly groove 10b and then abut against the hand tool 30. In this way, multiple push rods 231 together clamp and fix the hand tool 30.

[0046] Through the above solution, this application effectively solves the problem of automatic reset of clamping component 23, ensures convenient and smooth insertion and removal operation of hand tool 30, improves the positioning stability of hand tool 30 in assembly slot 10b, and prevents dust from entering the optical element area of ​​hand tool 30 head through perforation 10c, thereby enhancing assembly sealing performance.

[0047] Please see Figures 4 to 6 This application further proposes that the end of the slider 232 away from the push rod 231 is provided with a rolling pulley 232a, and the rolling pulley 232a is slidably connected in the eccentric groove 222a.

[0048] In practical applications, the rolling pulley 232a refers to a mechanical element that converts sliding friction into rolling friction. It can be implemented using miniature ball bearings or roller bearings, with the aim of significantly reducing frictional resistance during movement. The rolling pulley 232a is slidably connected in the eccentric groove 222a, which can be understood as the rolling pulley achieving relative displacement in the eccentric groove 222a by rolling. The purpose is to avoid direct rigid contact between the slider 232 and the groove wall of the eccentric groove 222a, thereby reducing local stress concentration and the risk of wear.

[0049] Specifically, when the trigger key 21 is pressed, the rack 221 drives the gear disk 222 to rotate, and the eccentric groove 222a of the gear disk 222 moves along the inclined trajectory. The slider 232 rolls in the eccentric groove 222a through the rolling pulley 232a at its end, thereby driving the push rod 231 to overcome the elastic force of the reset elastic element 233 and extend out of the through hole 10c to achieve the clamping of the hand tool 30. Due to the application of the rolling pulley 232a, the relative motion between the slider 232 and the eccentric groove 222a changes from sliding friction to rolling friction, and the coefficient of friction is greatly reduced. This allows the slider 232 to move smoothly along the complex inclined path of the eccentric groove 222a during the rotation of the gear disk 222, effectively avoiding the jamming problem caused by the accumulation of frictional heat or the embedding of dust, while improving the response sensitivity of the trigger key 21.

[0050] As a specific implementation method, the solution of this application is implemented as follows: the rolling pulley 232a can be a miniature ball bearing made of stainless steel. Its outer ring forms point contact with the groove wall of the eccentric groove 222a, and the inner ring is fixed to the end of the slider 232 by a tight fit, so as to ensure that the rolling pulley 232a can roll freely without axial displacement when the eccentric groove 222a moves.

[0051] The above technical solution effectively reduces friction and wear between the slider and the eccentric groove, prevents jamming during the clamping operation, and thus ensures the reliability of the gripper and the long-term operational stability of the clamping mechanism.

[0052] Please see Figure 3 and Figure 4 This application further proposes that the clamping member 23 also includes a flexible part 232b at one end of the push rod 231 that passes through the through hole 10c, the flexible part 232b being used to contact the hand tool 30.

[0053] Specifically, the flexible part 232b refers to the soft contact component provided at the end of the push rod 231. It can be made of rubber, soft polyurethane or elastomer material. Its purpose is to avoid scratches caused by hard friction and improve the sealing performance of the contact interface through its soft characteristics.

[0054] Specifically, the solution of this application uses the contact between the flexible part 232b and the surface of the hand tool 30 to absorb mechanical impact during the clamping process by utilizing the elastic deformation of the flexible part 232b, thereby preventing damage to the outer surface of the hand tool 30. At the same time, the flexible part 232b adaptively fills the tiny gaps in the assembly groove 10b, forming a continuous airtight barrier, effectively preventing external dust from entering the inner cavity 10a through the perforation 10c and the assembly groove 10b, thereby protecting the integrity of the optical element area of ​​the head of the hand tool 30.

[0055] As a preferred embodiment, the solution of this application is specifically implemented as follows: the flexible part 232b can be a ring-shaped rubber pad, which is fixed to the end of the push rod 231 by an interference fit. When the clamping member 23 extends under the drive of the transmission component 22, the rubber pad fits tightly against the outer peripheral wall of the hand tool 30, and uses its elastic deformation to achieve damage-free clamping and effective sealing.

[0056] Through the above solution, this application effectively avoids the problem of scratches on the outer surface of the hand tool 30 and enhances the sealing performance of the assembly groove 10b, ensuring the cleanliness of the optical components at the head of the hand tool 30, thereby ensuring the stability of laser output and the reliability of long-term equipment operation.

[0057] Please see Figure 3 This application further proposes that the push rod 231 has a mounting hole at one end away from the reset elastic member 233, and one end of the flexible part 232b is movably connected to the mounting hole.

[0058] The mounting hole refers to the structural feature at the end of the push rod 231 used to fix the flexible part 232b. It can be implemented using different geometric shapes such as through holes, blind holes, or annular grooves. Its purpose is to provide a precise positioning reference point for the flexible part 232b and prevent the flexible part 232b from shifting due to vibration during the reciprocating motion of the push rod 231. The movable connection refers to the connection method that maintains relative motion freedom between the flexible part 232b and the mounting hole. It can be implemented using mechanical cooperation forms such as hinge structure, snap-fit ​​connection, or ball joint. Its purpose is to allow the flexible part 232b to automatically adjust the contact angle when the hand tool 30 is inserted or pulled out, reduce stress concentration, and maintain uniform contact with the surface of the hand tool 30.

[0059] Specifically, the solution of this application, through the coordinated design of the mounting hole and the movable connection, ensures the positional stability of the flexible part 232b by using the mounting hole as a fixed fulcrum when the push rod 231 moves axially along the through hole 10c under the drive of the trigger key 21. At the same time, the movable connection structure allows the flexible part 232b to swing slightly around the mounting hole, thereby tightly wrapping the outer wall of the hand tool 30 under the action of clamping force to form a circumferential seal, effectively preventing dust from entering through the bottom of the assembly groove 10b. Moreover, this design avoids the interference of the deformation of the reset elastic element 233 on the contact accuracy of the flexible part 232b, ensuring the continuous reliability of the sealing performance during the clamping action.

[0060] As a preferred embodiment, the solution of this application is specifically implemented as follows: A circular through hole is machined at the end of the push rod 231 away from the reset elastic element 233 as a mounting hole, and a spherical protrusion is provided at one end of the flexible part 232b. The spherical protrusion is movably embedded in the mounting hole to form a ball joint connection. The flexible part 232b is made of polyurethane elastomer to form a ring structure, and its inner diameter is slightly smaller than the outer peripheral wall size of the hand tool 30. When the hand tool 30 is inserted into the assembly groove 10b, the flexible part 232b undergoes elastic deformation under the push of the push rod 231 and tightly fits the surface of the hand tool 30. At the same time, the ball joint connection allows the flexible part 232b to automatically adjust its posture with the insertion angle of the hand tool 30 to ensure that there is no gap at the sealing interface.

[0061] Through the above solution, this application ensures the structural stability of the flexible part 232b during dynamic clamping, effectively prevents the flexible part 232b from falling off or shifting due to connection failure, significantly improves the sealing performance of the clamping mechanism 20 to the bottom of the assembly groove 10b, and prevents dust from entering the optical element area of ​​the handpiece 30 head through the gap between the handpiece 30 and the assembly groove 10b, thereby ensuring the stability of laser output quality and the reliability of equipment lifespan.

[0062] Please see Figure 8 In this regard, this application further proposes that the flexible part 232b is a silicone retaining ring.

[0063] Among them, the flexible part 232b refers to the flexible contact component installed at the end of the push rod 231. It can be realized by using a ring structure made of silicone material, specifically an O-ring, a D-ring, or a ring structure with a sealing lip. Its purpose is to achieve a tight fit with the surface of the hand tool through elastic deformation, providing cushioning and sealing functions. The silicone retaining ring can be understood as a ring clamping structure made of silicone material. Its purpose is to use the high elasticity and chemical stability of silicone to form a continuous sealing interface, effectively blocking the intrusion of external contaminants.

[0064] Specifically, the solution of this application adopts a silicone retaining ring design in the flexible part 232b, which allows the silicone retaining ring to fit tightly against the clamping groove 30a on the outer peripheral wall of the hand tool 30 during the extension of the push rod 231, forming a continuous sealing interface. At the same time, the flexibility of the silicone material allows the retaining ring to adapt to changes in the surface contour of the hand tool, and to distribute stress evenly under the action of clamping force, avoiding local stress concentration caused by excessive material hardness. In addition, the weather resistance and chemical stability of silicone ensure that the sealing performance is maintained during repeated insertion and removal operations, effectively preventing dust from entering the optical element area of ​​the hand tool head through the assembly groove 10b.

[0065] As a specific embodiment, the solution of this application is implemented as follows: the flexible part 232b can be made of silicone O-ring, which is movably connected to the mounting hole at the end of the push rod 231; when the hand tool 30 is inserted into the assembly groove 10b, the push rod 231 extends under the drive of the transmission component 22, and the silicone O-ring tightly fits the clamping groove 30a on the outer peripheral wall of the hand tool 30 to form an effective sealing interface.

[0066] The above technical solution effectively prevents dust from entering the surface of the optical element at the head of the handpiece 30 through the assembly slot 10b, thus avoiding interference with the laser output quality. It also improves clamping stability and extends the service life of the equipment.

[0067] Please see Figure 4 This application further proposes that the clamping mechanism 20 also includes a first limiting part and a second limiting part disposed in the inner cavity 10a. The first limiting part and the second limiting part are located at both ends of the rack 221 and are spaced apart. The first limiting part and the second limiting part are used to limit the movement range of the rack 221.

[0068] In practical applications, the first limiting part refers to the blocking structure set at one end of the rack 221, which can be implemented by components such as bosses, baffles or rigid limiting pins, with the purpose of limiting the excessive displacement of the rack 221 to one end; the second limiting part refers to the blocking structure set at the other end of the rack 221, which can be implemented by structures such as grooves, limiting blocks or elastic buffer elements, with the purpose of limiting the excessive displacement of the rack 221 to the other end.

[0069] Specifically, the first and second limiting parts form physical limiting boundaries at both ends of the rack 221, constraining the linear reciprocating motion range of the rack 221 driven by the trigger key 21. When the trigger key 21 is operated, the rack 221 moves axially, and the first and second limiting parts respectively limit the maximum displacement position of the rack 221, ensuring that the rack 221 moves only within a preset stroke, thereby ensuring the accuracy of the rotation angle of the gear disk 222, and enabling the clamping member 23 to achieve stable clamping through the sliding of the eccentric groove 222a.

[0070] As a specific embodiment, the solution of this application is implemented as follows: the first limiting part is a metal protrusion provided in the inner cavity 10a, and the second limiting part is a rubber buffer pad provided in the inner cavity 10a. The two are located at the two ends of the rack 221 respectively, and contact each other when the rack 221 moves to the limit position.

[0071] Through the above solution, this application effectively prevents the rack 221 from displacing beyond the design stroke, ensures that the clamping member 23 can accurately clamp the hand tool 30, avoids mechanism jamming, and improves the stability of the hand tool 30 assembly and the reliability of operation.

[0072] Please see Figure 3 This application further proposes that the outer peripheral wall of the hand tool 30 is provided with a clamping groove 30a, which is arranged around the periphery of the hand tool 30 for inserting the clamping member 23.

[0073] The clamping groove 30a can be understood as an annular groove structure set on the outer peripheral wall of the hand tool 30. It can be implemented by a continuous groove or a segmented groove. Its purpose is to provide an embedding and positioning point for the clamping member 23 and avoid relative sliding caused by the smooth outer wall. The clamping groove 30a is set around the periphery of the hand tool 30 so that multiple clamping members 23 can be evenly distributed along the circumference of the hand tool 30, providing a balanced clamping force in all directions and preventing the hand tool 30 from shifting in the assembly groove 10b.

[0074] Specifically, the solution of this application achieves the overall function through the mechanical engagement of the clamping groove 30a and the clamping member 23. When the trigger key 21 is triggered, the transmission component 22 drives the clamping member 23 to extend into the assembly groove 10b. The end of the clamping member 23 is precisely embedded in the clamping groove 30a to form a firm lock. At the same time, the groove structure acts as a physical barrier to prevent dust from entering from the clamping interface, thereby ensuring the positioning stability and sealing of the hand tool 30 in the assembly groove 10b.

[0075] As a specific implementation, the outer peripheral wall of the hand tool 30 is formed with a continuous clamping groove 30a by a precision injection molding process. The end surface of the clamping member 23 is made of smooth metal material. When the clamping member 23 is inserted into the clamping groove 30a, the two fit tightly together, ensuring that the hand tool 30 does not shake in the assembly groove 10b and effectively blocks external contaminants.

[0076] Through the above solution, the positioning stability of the handpiece 30 in the assembly slot 10b is improved, and the sealing of the clamping interface effectively prevents dust from entering the head area of ​​the handpiece 30, ensuring the quality of laser output and the long-term reliability of the equipment.

[0077] In one specific embodiment, when the handpiece needs to be assembled with the main unit of the therapeutic instrument, simply insert one end of the handpiece into the assembly slot 10b of the main body 10 of the therapeutic instrument, and then drive the trigger key 21. The trigger key 21 drives the rack 221 of the transmission component 22 to rotate the gear disk 222. The gear disk 222 guides the push rods 231 of multiple clamping members 23 into the assembly slot 10b through multiple eccentric slots 222a. The flexible part 232b on one end of the push rod 231 extending into the assembly slot 10b elastically abuts against the end of the handpiece extending into the assembly slot 10b. The flexible parts 232b of the multiple clamping members 23 simultaneously clamp the handpiece located therein. In this way, after the handpiece is inserted into the assembly slot 10b, the handpiece and the assembly slot 10b form a sealed cavity, which will not be covered by dust from the external environment, thus affecting the laser output quality of the handpiece. Subsequently, the multiple clamping members 23 extend into the assembly slot 10b and clamp the handpiece, thereby fixing the handpiece. When disassembly is required, simply drive the multiple clamping parts 23 to retract into the inner cavity 10a of the treatment device body 10, so that the hand can be easily removed from the assembly slot 10b without causing interference.

[0078] Furthermore, this utility model also proposes a medical device, which includes a hand and the aforementioned therapeutic instrument main unit. The hand and the therapeutic instrument main unit are connected by an optical fiber. The laser emitted by the therapeutic instrument main unit is transmitted to the hand through the optical fiber, and the hand is used to guide the laser to the area to be treated.

[0079] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
