Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a quick clamping mechanism for a filter. Background Art

[0002] With the continuous improvement of medical equipment, the main unit with circulating smoke exhaust function is being used more and more widely in abdominal surgery. During the operation, the driving shaft of the main unit rotates, driving the rotating shaft of the filter to rotate, so that the pump head in the filter moves to generate negative pressure. The gas in the human body and the smoke generated during the operation are attracted into the filter. The filter filters the gas and then transports it back to the human body to maintain the pressure balance in the abdominal cavity, thereby maintaining the clarity of the operating field during the operation and improving the doctor's work efficiency.

[0003] During abdominal surgery, doctors need a quiet operating environment, while nurses or assistants need convenient surgical instruments to ensure the smooth progress of the operation. Since the filter is a disposable instrument, it needs to be frequently disassembled and replaced, and the filter needs to be reliably fixed during operation to prevent the filter from making noise due to vibration, which in turn affects the surgical operation. In the prior art, in order to ensure that the filter can be reliably fixed, screws and other connectors are generally used to fix the filter on the mounting seat. This structure is not convenient for disassembly and assembly of the filter, and the assembly takes a long time and the work efficiency is low. In order to ensure the sterile and clean state of the filter, the filter must be installed when preparing for surgery. The clamping mechanism that takes a long time to assemble and has low work efficiency is not convenient for abdominal surgery. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the present invention aims to provide a quick-clamping mechanism for a filter, which can conveniently and quickly disassemble and replace the filter, improve work efficiency, and can stably and reliably clamp the filter.

[0005] In order to solve the above problems, the technical solution adopted by the present invention is as follows: a quick clamping mechanism for a filter, comprising: a base; a positioning assembly, comprising a positioning seat arranged on the base, a first positioning hole being opened inside the positioning seat; and a clamping assembly, comprising a clamping ring, a clamping claw and a first elastic member, the clamping ring being sleeved on the outside of the positioning seat, a plurality of sliding members being fixedly connected to the clamping ring, a plurality of sliding members being distributed along the circumference of the clamping ring, a plurality of clamping claws being distributed along the circumference of the positioning seat, a first end of each of the clamping claws being rotatably connected to the positioning seat, and each of the The claws are all provided with a sliding groove, and the multiple sliding parts are inserted into the sliding grooves of the multiple claws one by one. The two ends of the first elastic part are respectively connected to the clamping ring and the positioning seat; the first positioning hole is used to position the sleeve of the filter, and the first elastic part can make the clamping ring rotate circumferentially along the first direction relative to the positioning seat. When the clamping ring rotates, it can drive the sliding part to slide circumferentially along the sliding groove in the first direction, so that the first end of the claw rotates relative to the positioning seat, and the second end of the claw moves toward the direction of the first positioning hole and fits and clamps the filter.

[0006] Compared with the prior art, the beneficial effect of the present invention is that: when in use, the snap ring is first rotated circumferentially along the second direction relative to the positioning seat, at which time the first elastic member is stretched. When the snap ring rotates circumferentially along the second direction relative to the positioning seat, the sliding member on the snap ring slides circumferentially in the second direction within the slide groove, thereby causing the second end of the claw to move in a direction away from the first positioning hole. Afterwards, the filter is inserted into the first positioning hole, and after the snap ring is released, the snap ring will rotate circumferentially in the opposite direction of the second direction, that is, circumferentially in the first direction, under the elastic restoring force of the first elastic member. When the snap ring rotates circumferentially in the first direction, it drives the sliding member to slide circumferentially in the first direction within the slide groove, thereby causing the first end of the claw to rotate relative to the positioning seat, and the second end of the claw to move toward the direction of the first positioning hole, and fit the filter tightly. Therefore, when removing or replacing the filter, one only needs to apply force to cause the clamping ring to rotate circumferentially in the second direction. When the clamping ring is loosened, the clamping ring automatically rotates circumferentially in the first direction under the action of the first elastic member. Through the aforementioned linkage, the claws can position and clamp the filter, achieving rapid filter removal and improved work efficiency. The first positioning hole, the multiple claws, and the first elastic member work together to ensure that the filter is stably and reliably clamped, preventing the filter from vibrating and generating noise during operation, which could affect surgical procedures.

[0032] The embodiments of the present invention are described in detail below. Figures 1 to 7The embodiment of the present invention provides a quick clamping mechanism of a filter, including a base 100, a positioning assembly 200 and a clamping assembly 300. The positioning assembly 200 includes a positioning seat 210 provided on the base 100, and a first positioning hole 211 is opened inside the positioning seat 210; the clamping assembly 300 includes a clamping ring 310, a claw 320 and a first elastic member 330, the clamping ring 310 is sleeved on the outer side of the positioning seat 210, and a plurality of sliding members 340 are fixedly connected to the clamping ring 310, and the plurality of sliding members 340 are distributed along the circumference of the clamping ring 310, and the claws 320 are distributed along the circumference of the positioning seat 210. The first end of each claw 320 is rotatably connected to the positioning seat 210, and each claw 320 is opened with a sliding groove 321. The plurality of sliding members 340 are correspondingly inserted into the sliding grooves 321 of the plurality of claws 320, and the two ends of the first elastic member 330 are respectively connected to the clamping ring 310 and the positioning seat 210. The first positioning hole 211 is used to position the sleeve filter 500. The first elastic member 330 can make the clamping ring 310 rotate circumferentially along the first direction relative to the positioning seat 210. When the clamping ring 310 rotates, it can drive the sliding member 340 to slide circumferentially along the sliding groove 321 along the first direction, so that the first end of the clamping claw 320 rotates relative to the positioning seat 210, and the second end of the clamping claw 320 moves toward the direction of the first positioning hole 211 and fits the clamping filter 500.

[0033] During use, the snap ring 310 is first rotated circumferentially in the second direction relative to the positioning seat 210, at which point the first elastic member 330 is stretched. As the snap ring 310 rotates circumferentially in the second direction relative to the positioning seat 210, the sliding member 340 on the snap ring 310 slides circumferentially in the second direction within the slide groove 321. Specifically, the sliding member 340 slides within the slide groove 321 toward the first end of the claw 320, causing the second end of the claw 320 to tilt outward, moving the second end of the claw 320 away from the first positioning hole 211. Subsequently, the filter 500 is inserted into the first positioning hole 211, and the snap ring 310 is released. Under the elastic restoring force of the first elastic member 330, the snap ring 310 rotates circumferentially in the opposite direction of the second direction, that is, in the first direction. When the clamping ring 310 rotates circumferentially in the first direction, it drives the sliding member 340 to slide circumferentially in the first direction within the sliding groove 321. That is, the sliding member 340 slides within the sliding groove 321 toward the second end of the claw 320, thereby squeezing the second end of the claw 320 inward, causing the first end of the claw 320 to rotate relative to the positioning seat 210, and the second end of the claw 320 to move toward the first positioning hole 211 and engage the filter 500. Therefore, when disassembling and replacing the filter 500, it is only necessary to apply force to cause the clamping ring 310 to rotate circumferentially in the second direction. When the clamping ring 310 is loosened, the clamping ring 310 automatically rotates circumferentially in the first direction under the action of the first elastic member 330. Through the aforementioned linkage action, the claw 320 can be positioned and clamped to the filter 500, thereby achieving rapid disassembly and assembly of the filter 500 and improving work efficiency. Under the joint action of the first positioning hole 211, the plurality of claws 320 and the first elastic member 330, the mechanism can stably and reliably clamp the filter 500 to prevent the filter 500 from vibrating and making noise during operation, thereby affecting the surgical operation. Figure 1 The counterclockwise direction in the second direction is Figure 1 Clockwise direction in .

[0034] Further, refer to Figures 2 to 4The sidewall of the first positioning hole 211 is provided with a plurality of through-grooves 212, which are distributed circumferentially along the first positioning hole 211. The positions of the through-grooves 212 correspond one-to-one to the positions of the plurality of claws 320, and the through-grooves 212 pass through the side of the positioning seat 210. When the sliding member 340 slides circumferentially along the sliding groove 321, the second ends of the claws 320 extend inward from the through-grooves 212 or move outward away from the first positioning hole 211. When the second ends of the plurality of claws 320 need to be moved away from each other to release or insert the filter 500, the retaining ring 310 is rotated in the second direction, and the sliding member 340 slides circumferentially in the second direction, that is, the sliding member 340 slides toward the first ends of the claws 320, thereby causing the second ends of the plurality of claws 320 to move outward from the through-grooves 212 away from the first positioning hole 211. When the clamping ring 310 is loosened, the first elastic member 330 causes the clamping ring 310 to rotate circumferentially in the first direction. At this time, the sliding member 340 slides along the second end of the claw 320 within the sliding groove 321, thereby squeezing the second end of the claw 320 inward, causing the second end of the claw 320 to extend inward from the through-groove 212 into the first positioning hole 211 and fit closely to the outer circumference of the filter 500. Preferably, three groups of claws 320 are provided, with the angle between two adjacent groups of claws 320 being 120°.

[0035] Specifically, refer to Figure 2 and Figure 3The first end of the chute 321 is closer to the first positioning hole 211 than the second end of the chute 321. When the slider 340 is located at the first end of the chute 321, the second ends of the plurality of claws 320 move away from each other. When the slider 340 is located at the second end of the chute 321, the second ends of the plurality of claws 320 move toward each other and clamp the outer periphery of the filter 500. Because the position of the slider 340 on the clamping ring 310 is fixed, the distance between the slider 340 and the outer periphery of the positioning seat 210 remains unchanged. However, when the claws 320 remain stationary, the distances between different positions on the chute 321 and the outer periphery of the positioning seat 210 vary. When the slider 340 moves along the chute 321, the constant distance between the slider 340 and the positioning seat 210 causes the first ends of the claws 320 to rotate relative to the positioning seat 210, thereby causing the second ends of the claws 320 to move toward or away from the first positioning hole 211. Specifically, the snap ring 310 is provided with a plurality of guide grooves 311, which are distributed along the circumference of the snap ring 310, and the length direction of the guide grooves 311 extends along the circumference of the snap ring 310. The positioning seat 210 is correspondingly provided with a plurality of guide posts 213, which are inserted into the plurality of guide grooves 311 in a one-to-one correspondence and can slide circumferentially relative to the guide grooves 311. When the snap ring 310 is rotated, the guide grooves 311 on the snap ring 310 will slide relative to the guide posts 213 on the positioning seat 210. The cooperation between the guide posts 213 and the guide grooves 311 not only provides a guiding function, but also limits the snap ring 310 in the axial direction, making the circumferential rotation of the snap ring 310 smoother and more stable, and allowing the claw 320 to accurately enter and exit the through-slot 212.

[0036] Specifically, continue to refer to Figures 2 to 4The inner side surface of the claw 320 has a clamping surface 322. The clamping surface 322 is curved and can match the cylindrical outer periphery of the filter 500, making the clamping of the claw 320 more reliable. The clamping surface 322 can also be coated with anti-slip material or provided with anti-slip textures to increase the friction between the clamping surface 322 and the filter 500. Specifically, a first transition bevel 323 is connected between the clamping surface 322 and the end of the first end of the claw 320. When the claw 320 moves from the through-slot 212 to the interior of the first positioning hole 211 to clamp the filter 500, the first transition bevel 323 prevents the claw 320 from interfering with the outer periphery of the filter 500. Specifically, a second transition slope 324 is connected between the outer side surface of the claw 320 and the end of the second end of the claw 320. When the second end of the claw 320 enters or exits the through-groove 212, the second transition slope 324 can prevent the outer side surface of the claw 320 from interfering with the side wall of the through-groove 212. At the same time, in this embodiment, when the sliding member 340 is located at the first end of the slide groove 321, the extension distance of the second end of the claw 320 is the largest. At this time, since the second transition slope 324 reduces the width of the second end of the claw 320, the second end of the claw 320 will not protrude outward from the side of the retaining ring 310, which not only makes the appearance of the overall structure more beautiful, but also prevents the second end of the claw 320 from hitting bystanders when moving outward.

[0037] Further, refer to Figures 1 to 4 The first elastic member 330 is a spring, and its axis extends along the circumference of the positioning seat 210. When the snap ring 310 rotates in the second direction, the first elastic member 330 can be significantly stretched. When the snap ring 310 is released, the large elastic restoring force causes the snap ring 310 to rotate rapidly in the first direction, allowing the claw 320 to quickly clamp the filter 500. Specifically, a first spring retaining seat 214 is provided on the outer periphery of the positioning seat 210, and the snap ring 310 is provided with a second spring retaining seat 312. The spacing between the first spring retaining seat 214 and the second spring retaining seat 312 is adjustable, and the first and second spring retaining seats 214 and 312 are connected at both ends of the first elastic member 330, respectively. The adjustable spacing allows the elastic force of the first elastic member 330 to be adjusted in the clamped state, ensuring that the elastic force of the first elastic member 330 is sufficient to enable the claw 320 to clamp the filter 500. Specifically, the clamping ring 310 is connected to a handle 313 , and the handle 313 is provided with a pressing portion 3131 , so that the user can press the pressing portion 3131 of the handle 313 downward to rotate the clamping ring 310 along the second direction.

[0038] Further, refer to Figures 5 to 7The present mechanism further includes a drive assembly 400 disposed on the base 100. The drive assembly 400 includes a drive motor 410. The outer end of the drive shaft 411 of the drive motor 410 has a plug-in portion 4111. The width of the plug-in portion 4111 gradually decreases from the inside to the outside. The outer end of the rotating shaft 510 of the filter 500 has a slot 511. The width of the slot 511 gradually increases from the inside to the outside. The plug-in portion 4111 can be plugged into the slot 511. The matching mode of the plug-in portion 4111 and the slot 511 can, on the one hand, facilitate the connection between the rotating shaft 510 and the drive shaft 411, achieving quick disassembly and assembly without jamming. On the other hand, it can ensure a tight fit between the rotating shaft 510 and the drive shaft 411, making the movement of the rotating shaft 510 more stable when the drive shaft 411 drives the rotating shaft 510 to rotate. Specifically, the driving assembly 400 further includes a cooling fan 430 provided on the driving motor 410 . The cooling fan 430 is fixed to the side of the driving motor 410 by a buckle, and can provide heat dissipation for the driving motor 410 .

[0039] Furthermore, the drive assembly 400 also includes a motor mounting base 420 provided on the base 100, and the motor mounting base 420 is used to install the drive motor 410. The positioning assembly 200 also includes a plurality of positioning pins 220, and the plurality of positioning pins 220 are distributed circumferentially on the bottom wall of the first positioning hole 211, and the first end of the positioning pin 220 is connected to the motor mounting base 420 through the second elastic member 230. The bottom wall of the filter 500 is provided with a plurality of second positioning holes 520, and the positions of the plurality of second positioning holes 520 correspond one-to-one to the positions of the plurality of positioning pins 220. When the filter 500 is positioned and inserted into the first positioning hole 211, the second end of the positioning pin 220 is positioned and inserted into the second positioning hole 520. The connection between the locating pin 220 and the second elastic member 230 allows the filter 500 and the drive assembly 400 to be connected not only to the rotating shaft 510 and the drive shaft 411, but also to connect the bottom of the filter 500 to the motor mounting seat 420. Combined with the connection between the filter 500, the locating seat 210, and the clamping assembly 300, the filter 500 can be stably and reliably fixed to the base 100 and can achieve a reliable connection with the drive assembly 400, thereby greatly reducing the vibration of the filter 500. When installing the filter 500, first place the filter 500 into the first locating hole 211, then rotate the filter 500 so that the multiple second locating holes 520 on the filter 500 connect one by one with the multiple locating pins 220, achieving the purpose of positioning and supporting, balancing the force on the filter 500, and ensuring the coaxiality between the rotating shaft 510 and the drive shaft 411.

[0040] Specifically, the base 100 includes a bottom plate 110, a buffer column 120, a support seat 130, a buffer seat 140 and a buffer pad 150. There are multiple buffer columns 120 distributed along the upper end surface of the bottom plate 110, and the upper and lower ends of the buffer column 120 are respectively connected to the support seat 130 and the bottom plate 110. The buffer seat 140 is connected to the upper end surface of the bottom plate 110. The two sides of the buffer pad 150 are respectively connected to the buffer seat 140 and the support seat 130. The support seat 130 is used to support the positioning seat 210. The buffer column 120, buffer seat 140 and buffer pad 150 can play a role in buffering and shock absorption when the filter 500 is working, further avoiding the noise generated when the filter 500 is working. The buffer column 120 is in the shape of a stepped shaft, which can not only play a role in buffering and shock absorption, but also facilitate the installation and connection of the support seat 130. Specifically, the support base 130 is provided with a positioning groove 131 to facilitate the positioning of the positioning base 210 and the motor mounting base 420. A micro switch 170 is installed on the support base 130. The micro switch 170 passes through the positioning base 210 and extends into the first positioning hole 211. When the filter 500 is installed in the target position, the filter 500 triggers the micro switch 170, which sends a signal to the host computer to achieve the final position detection. Specifically, the base 100 also includes a riding card 160 provided on the support base 130. The riding card 160 and the positioning groove 131 fix and position the positioning base 210 from both ends to improve the positioning effect of the positioning base 210.
