Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a spinal surgical suction device with traction and fixation function. Background Technology

[0002] A spinal surgical suction device is a medical instrument primarily used to suction and clean the surgical site or surrounding tissues during surgery. It effectively removes blood, tissue fluid, and other fluids generated during surgery, maintaining a clear surgical field and preventing intraoperative infection and complications.

[0003] Currently, spinal surgery, especially multi-segment surgery, requires the assistance of multiple assistants. One assistant is responsible for holding the suction device, following the surgeon's field of vision, and aspirating any potential local bleeding. However, the current status of spinal surgical suction devices is as follows:

[0004] On the one hand, there is a shortage of doctors, especially spinal surgeons, in China, and the number of patients is surging. Sometimes it is not possible to arrange a dedicated person to suck blood, and when the assistant is not skilled enough, he cannot find a suitable field of vision according to the surgeon's wishes.

[0005] On the other hand, some deep structures, such as the spinal canal, often require the replacement of a smaller diameter suction device during surgery to achieve more precise blood suction. However, this replacement process requires a second positioning of the field of vision, which interferes with the surgical process. Therefore, this application provides a spinal surgical suction device with traction and fixation function to meet the needs. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a spinal surgical suction device with traction and fixation function to solve the problems of existing suction device heads requiring a dedicated person to hold and follow the surgeon's field of vision, and the inability to actively adjust the smaller diameter suction device according to the delicate structure during spinal surgery. At the same time, the replacement process involves secondary positioning of the field of vision, which interferes with the surgical process.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] A spinal surgical aspirator with traction and fixation function includes an aspirator head connected to the front end of the aspirator tube, a traction and fixation component installed on the outside of the aspirator head, a first telescopic tube with a T-shaped vertical cross-section slidably sleeved at the front end of the aspirator head, a second telescopic tube with a T-shaped vertical cross-section slidably sleeved at the front end of the first telescopic tube, a filter screen fixed at the front inlet of the second telescopic tube, and a step-by-step telescopic component connected between the aspirator head and the first and second telescopic tubes, the step-by-step telescopic component being used to achieve step-by-step extension and retraction of the first and second telescopic tubes;

[0009] A cleaning component is used to clean one side surface of the filter screen, and the cleaning component is installed on the filter screen.

[0010] Optionally, the traction fixing component includes a V-shaped frame, both ends of which are integrally formed with traction plates through a first weakening groove, and the ends of the two traction plates away from the first weakening groove are integrally formed with hooks.

[0011] Optionally, a universal flexible shaft is fixed to the top of the central tip of the V-shaped frame, and a clamping plate is fixed to the top of the universal flexible shaft. The vertical cross-section of the clamping plate is C-shaped, and both ends of the top of the clamping plate are provided with clearance portions. A second weakening groove is provided in the middle of the inner wall of the clamping plate.

[0012] Optionally, the progressive telescopic component includes a first air inlet chamber circumferentially formed in the inner wall of one end of the suction head, one end of the suction head being slidably sleeved on the outside of the first telescopic tube through the first air inlet chamber, a sealing ring being fixedly connected to the periphery of one end of the first telescopic tube inside the first air inlet chamber, a second air inlet chamber circumferentially formed in the inner wall of the first telescopic tube, the second air inlet chamber being slidably sleeved on the outside of the second telescopic tube, and a sealing ring being fixedly connected to the periphery of one end of the second telescopic tube inside the second air inlet chamber.

[0013] Optionally, one end of a plurality of first reset springs arranged in a ring array is fixedly connected to one side of the inner wall of the first air intake chamber, and the other end of each of the first reset springs is fixedly connected to the end wall of the first telescopic tube. One end of a plurality of second reset springs arranged in a ring array is fixedly connected to one side of the inner wall of the second air intake chamber, and the other end of each of the second reset springs is fixedly connected to the end wall of the second telescopic tube.

[0014] Optionally, the top of the first air intake chamber is provided with a Z-shaped air intake channel formed in the inner wall of one end of the suction head. The bottom end of the Z-shaped air intake channel is connected to the first air intake chamber, and the top end of the Z-shaped air intake channel is connected to the strip-shaped airbag. The strip-shaped airbag is fixed to the top end of one end of the suction head. The top of the strip-shaped airbag is squeezed by a squeezing sleeve. The squeezing sleeve is slidably sleeved on the outside of two symmetrically arranged guide seats. The guide seats are all fixed to the outside of the suction head. The vertical cross-section of the guide seats is an inverted L-shaped structure. A squeezing slope is provided at the opening of one end of the squeezing sleeve.

[0015] Optionally, the first telescopic tube has a plurality of air inlets arranged in a ring array at one end located in the first air inlet chamber, and the second air inlet chamber is connected to the first air inlet chamber through the plurality of air inlets.

[0016] Optionally, the front end of the extrusion sleeve is blocked by a limiting seat with an n-shaped vertical cross section. The limiting seat is slidably sleeved on the outside of the two guide seats. Both sides of the limiting seat are threaded with hand-tightening screws, and the opposite ends of the two hand-tightening screws are pressed against the outside of the guide seats.

[0017] Optionally, an annular protrusion is fixedly connected to the periphery of one end of the suction head, and a rotating sleeve is movably sleeved on the outer side of the annular protrusion. A plurality of first teeth arranged in an annular array are fixedly connected to the inner wall of the rotating sleeve. A plurality of circular rotating blocks are also provided at one end of the suction head. A plurality of second teeth arranged in an annular array are fixedly connected to the periphery of each rotating block. Each rotating block engages with a plurality of first teeth through a plurality of second teeth. A screw is fixedly connected to the central mounting hole of each rotating block. One end of each screw is rotatably connected to one end of the suction head, and one end of each screw extends into the first air inlet cavity and is threadedly sleeved with a blocking sleeve. The blocking sleeve is slidably sleeved on the outer side of the limiting rod. One end of the limiting rod is fixedly connected to the inner wall of one side of the first air inlet cavity. The end of the blocking sleeve away from the rotating block is movably connected to the end of the first telescopic tube located in the first air inlet cavity.

[0018] Optionally, the cleaning component includes a rotating rod rotatably connected at the center of the filter screen. A cleaning brush is fixedly attached to the periphery of one end of the rotating rod, and the brush surface of the cleaning brush is movably attached to the surface of the filter screen. The other end of the rotating rod extends into the interior of the suction head and is fixedly attached to a transmission column. The transmission column is perpendicular to the rotating rod, and one end of the transmission column away from the rotating rod is movably engaged in a spiral groove opened on the inner wall of the suction head.

[0019] Compared with the prior art, the present invention has at least the following beneficial effects:

[0020] In the above solution, by setting up traction fixation components and two first weakening grooves, the two traction plates can be used to pull open the opening of the spinal surgery site through hooks. Furthermore, the use of splints and universal flexible shafts allows the suction head to be fixed in position during local traction. This solves the problem of needing a dedicated person to suction blood, saving labor costs. Moreover, the position and angle of the suction head can be determined by the surgeon, making it convenient to use.

[0021] By setting up a stepped telescopic component, manually moving the squeezing sleeve forward from the rear end to the front end of the suction head causes it to slide forward on the two guide seats. This allows the squeezing sleeve to compress the strip-shaped airbag via the squeezing bevel, forcing air from the strip-shaped airbag to be delivered to the first air intake chamber through the Z-shaped air intake channel. This pushes the first telescopic tube forward, and simultaneously, multiple first return springs are compressed and deformed. Simultaneously, after extending a certain length, the first telescopic tube is limited by the blocking sleeve, thus ensuring the extended length of the first telescopic tube. If the first telescopic tube cannot extend further, the squeezing sleeve... As it continues to move forward, the strip-shaped airbag is further compressed, causing air within the airbag to enter the second air intake chamber through multiple air inlets. This pushes the second telescopic tube forward, while simultaneously compressing and deforming multiple second return springs. This allows the suction head to extend and retract in stages, avoiding frequent repositioning of the field of view when changing the thin suction head. It's worth noting that this structure achieves staged extension and retraction entirely through inflation, giving the front end of the second telescopic end a cushioning elasticity, preventing hard contact damage to the incision and blood suction area of ​​the spinal surgery site. Secondly, because each person... Since body shapes vary, the thickness of the spine also varies, resulting in different incision depths during spinal surgery. Another function of the aforementioned progressively telescopic components is to allow for adjustable telescopic extension for surgical incisions of varying depths. The extension length of the first telescopic tube can be determined by adjusting the front-to-back position of the limiting seat on the two guide seats. After adjustment, it can be fixed by tightening the two hand-tightening screws, thus blocking the front end of the compression sleeve and locking the distance the compression sleeve travels forward. This, in turn, locks the compression length of the strip-shaped airbag, ensuring air enters the first air intake chamber. The air volume in the second air intake chamber is fixed, and with the manual rotation of the rotating sleeve, the rotating sleeve drives multiple rotating blocks through the setting of multiple first and second teeth. This causes the screw connected to each rotating block to rotate, thereby causing the blocking sleeve to move forward or backward for adjustment. This allows the blocking sleeve to block the forward extension length of the first telescopic tube, ensuring that the forward extension length of the first telescopic tube is adjustable. The forward extension length of the second telescopic tube can be achieved by the limit seat continuing to move forward to compress the strip-shaped airbag, thus meeting the suction needs of openings at different depths in spinal surgery sites, and has a wide range of applications.

[0022] By setting up a clearing mechanism, when the first and second telescopic tubes need to retract to allow the surgeon to reserve the surgical field, the squeezing sleeve can be manually moved from front to back. This stops the squeezing sleeve from compressing the strip-shaped airbag. Under the action of the first and second return springs, the air in the first and second air intake chambers is drawn back into the strip-shaped airbag. At the same time, the end of the transmission column connected to the rear end of the rotating rod, away from the rotating rod, slides along the inner wall of the spiral groove. During the retraction process, the cleaning brush rotates through the rotating rod, thus removing the debris adsorbed on the surface of the filter screen. This prevents the first and second telescopic tubes from being obstructed by adsorption when they extend forward again to suction blood, providing a good anti-clogging effect.

Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0037] The following is a detailed description of a spinal surgical suction device with traction and fixation function provided by the present invention, in conjunction with the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0038] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0039] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0040] It is understood that the meanings of “on”, “above”, and “above” in this invention should be interpreted in the broadest manner, such that “on” means not only “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” means not only “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0041] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially related descriptive terms used herein can be interpreted similarly.

[0042] like Figure 1 and Figure 3 As shown, an embodiment of the present invention provides a spinal surgical aspirator with traction and fixation function, including an aspirator head 1 connected to the front end of the aspirator tube, a traction and fixation member 2 installed on the outside of the aspirator head 1, a first telescopic tube 11 with a vertical cross-section of T-shaped structure slidably sleeved at the front end of the aspirator head 1, a second telescopic tube 12 with a vertical cross-section of T-shaped structure slidably sleeved at the front end of the first telescopic tube 11, a filter screen 13 fixedly connected at the front end inlet of the second telescopic tube 12, a step-by-step telescopic member 3 connecting the aspirator head 1, the first telescopic tube 11, and the second telescopic tube 12, the step-by-step telescopic member 3 being used to achieve step-by-step telescopic extension and retraction of the first telescopic tube 11 and the second telescopic tube 12; and a cleaning member 4, which is used to clean one side surface of the filter screen 13, the cleaning member 4 being installed on the filter screen 13, and the end of the rotating rod 41 in the cleaning member 4 away from the cleaning brush 42 being movably connected to a spiral groove 44 opened on the inner wall of the aspirator head 1 through a transmission column 43.

[0043] The first telescopic tube 11 and the second telescopic tube 12 each have two symmetrically distributed keyways 111 on their outer sides. The first telescopic tube 11 is slidably connected to the front end of the suction head 1 through the two keyways 111, and the second telescopic tube 12 is slidably connected to the first telescopic tube 11 through the two keyways 111. The keyways 111 allow the first telescopic tube 11 and the second telescopic tube 12 to only telescopically move and not rotate. The filter screen 13 is hidden at the front end of the second telescopic tube 12, providing space for the cleaning brush 42 to be hidden, thereby avoiding the cleaning brush 42 from causing contact or damage to the opening of the patient's spinal surgery site. The outer periphery of the front end of the second telescopic tube 12 is rounded to avoid damage to the opening of the surgical site.

[0044] It is worth mentioning that the extension and retraction of the first telescopic tube 11 and the second telescopic tube 12 in the prior art generally adopts the method of snap-fit ​​or screw connection. However, these two extension and retraction adjustment methods require the extension and retraction adjustment of the first telescopic tube 11 and the second telescopic tube 12 separately, which is very inconvenient. The step-by-step extension component 3 uses air inflation to allow the first telescopic tube 11 to extend to a certain length, and then allows the second telescopic tube 12 to extend subsequently. The step-by-step extension and retraction method is more convenient to operate.

[0045] like Figure 3 and Figure 8 As shown, in order to be able to pull and fix the suction head 1 to the spinal surgery site without manual intervention, and to support and fix the angle of the suction head 1, the traction fixation component 2 is provided, which includes a V-shaped frame 21. Both ends of the V-shaped frame 21 are integrally formed with traction plates 23 through the first weakening groove 22. The ends of the two traction plates 23 away from the first weakening groove 22 are integrally formed with hooks 24. The top of the middle tip of the V-shaped frame 21 is fixedly connected to a universal flexible shaft 25. The top of the universal flexible shaft 25 is fixedly connected to a clamping plate 26. The vertical cross section of the clamping plate 26 is C-shaped. Both ends of the top of the clamping plate 26 are provided with clearance parts 262. The middle of the inner wall of the clamping plate 26 is provided with a second weakening groove 261.

[0046] The two clearance parts 262 make it easier to place the suction head 1 in the clamp 26, allowing the clamp 26 to deform and open through the second weakening groove 261 until the clamp 26 clamps and fixes the outside of the suction head 1. In addition, the universal flexible shaft 25 can be manually bent to actively adjust and fix the angle and position of the suction head 1, so as to meet the surgical field angle of the surgeon, without the need for assistants to hold it, thus reducing labor costs.

[0047] like Figures 4 to 10As shown, the direction in which the second telescopic tube 12 faces is considered the front side. In order to enable the first telescopic tube 11 and the second telescopic tube 12 to extend and retract in stages, and to facilitate suction adjustment for openings of different depths in the spine, and to allow for telescopic adjustment and variation for different fine structures in spinal surgery openings, the step-by-step telescopic component 3 is provided, including a first air inlet chamber 31 circumferentially opened in the inner wall of the front end of the suction head 1. The front end of the suction head 1 is slidably sleeved on the outside of the first telescopic tube 11 through the first air inlet chamber 31, that is, the outer wall of the first telescopic tube 11 is slidably connected in the first air inlet chamber 31. A sealing ring 33 is fixedly connected to the periphery of the first telescopic tube 11 away from the front end of the first telescopic tube 11. A second air inlet chamber 32 is circumferentially opened in the inner wall of the first telescopic tube 11. The second air inlet chamber 32 is slidably sleeved on the outside of the second telescopic tube 12, that is, the outer wall of the second telescopic tube 12 is slidably connected in the second air inlet chamber 32.A sealing ring 33 is also fixedly connected to the periphery of the second telescopic tube 12 away from its front end. Multiple first return springs 34 arranged in a ring array are fixedly connected to the inner front wall of the first air intake chamber 31. The other ends of each first return spring 34 are fixedly connected to the end wall of the first telescopic tube 11. Multiple second return springs 35 arranged in a ring array are fixedly connected to the inner front wall of the second air intake chamber 32. The other ends of each second return spring 35 are fixedly connected to the end wall of the second telescopic tube 12. A Z-shaped air intake channel 36 is also provided at the top of the first air intake chamber 31, located in the inner front wall of the suction head 1. The bottom end of the Z-shaped air intake channel 36 connects to the first air intake chamber 31. The top of the Z-shaped air intake channel 36 is connected to the strip-shaped airbag 37, which is fixed to the top of the front end of the suction head 1. The top of the strip-shaped airbag 37 is compressed by the compression sleeve 38. The compression sleeve 38 is slidably sleeved on the outside of two symmetrically arranged guide seats 381. The guide seats 381 are all fixed to the outside of the suction head 1. The vertical section of the guide seats 381 is an inverted L-shaped structure. The front opening of the compression sleeve 38 is provided with a compression bevel 39. The rear end of the first telescopic tube 11 is provided with multiple air intake holes 310 arranged in a ring array. The second air intake chamber 32 is connected to the first air intake chamber 31 through multiple air intake holes 310. The front end of the compression sleeve 38 is compressed by the vertical section. A limit seat 318 with an n-shaped structure blocks the flow. The limit seat 318 is slidably sleeved on the outside of two guide seats 381. Hand screws 319 are threaded onto both side walls of the limit seat 318. The opposite ends of the two hand screws 319 are pressed against the outside of the guide seats 381. An annular protrusion 312 is fixedly connected to the outer periphery of the front end of the suction head 1. A rotating sleeve 311 is movably sleeved on the outer side of the annular protrusion 312. Multiple first teeth 313 arranged in an annular array are fixedly connected to the inner wall of the rotating sleeve 311. Multiple circular rotating blocks 314 are also provided at the front end of the suction head 1. Multiple first teeth 313 arranged in an annular array are fixedly connected to the periphery of each rotating block 314. The second teeth 3141 are arranged in a row. Each rotating block 314 is engaged with multiple first teeth 313 through multiple second teeth 3141. A screw 315 is fixedly connected in the central mounting hole of each rotating block 314. The rear end of each screw 315 is rotatably connected to the front end of the suction head 1. The rear end of each screw 315 extends into the first air inlet chamber 31 and is threadedly fitted with a blocking sleeve 316. The blocking sleeve 316 is slidably fitted on the outside of the limiting rod 317. The front end of the limiting rod 317 is fixed to the front inner wall of the first air inlet chamber 31. The end of the blocking sleeve 316 away from the rotating block 314 is movably connected to the rear end of the first telescopic tube 11.

[0048] The limiting rod 317 is designed to ensure that the blocking sleeve 316 can move horizontally outside the limiting rod 317. The screw 315 is threadedly connected to the blocking sleeve 316. Therefore, when the screw 315 is driven to rotate, the blocking sleeve 316 can move outside the limiting rod 317, thereby limiting the length of the first telescopic tube 11 extending beyond the suction head 1. The overlapping mentioned here refers to fitting against the rear end of the first telescopic tube 11.

[0049] Among them, the strip-shaped airbag 37 is attached Figure 4 The air in the bladder is compressed, and air from the strip-shaped airbag 37 enters the first air intake chamber 31 and the second air intake chamber 32. The sealing ring 33 seals the rear ends of the second telescopic tube 12 and the first telescopic tube 11, preventing air leakage into the chambers of the first return spring 34 and the second return spring 35. The limiting seat 318 is adjusted by tightening and loosening the hand screw 319 to move it away from the front end of the suction head 1. This design allows the surgeon to manually move the squeezing sleeve 38 away from the front end of the suction head 1 when the surgeon needs to perform blood suction at the incision site of the spinal surgery. The push prevents the strip-shaped airbag 37 from being squeezed. Under the rebound and reset action of the first and second compression springs, the first telescopic tube 11 retracts into the suction head 1, and the second telescopic tube 12 retracts into the first telescopic tube 11. This provides the surgeon with a wider surgical field of view. After the operation, the surgeon can actively push the compression sleeve 38 forward. The position of the limiting seat 318 restricts the compression sleeve 38 from moving further, so that the first telescopic tube 11 and the second telescopic tube 12 can be completely reset to their original blood suction positions. However, the position of the limiting seat 318 is adjustable, so it can be adjusted for different spinal surgery positions.

[0050] like Figure 10 As shown, each blocking sleeve 316, screw 315, and limiting rod 317 is movably sleeved by the first return spring 34; and the first return spring 34 and the second return spring 35 are in a compressed state as shown in the attached figure; the length of the guide seat 381 is greater than the length of the extrusion sleeve 38, so as to reserve more rearward position for the extrusion sleeve 38, so that the extrusion sleeve 38 can extrude the strip airbag 37 within different length ranges.

[0051] like Figures 4 to 10As shown, in order to actively clean the surface of the filter screen 13 when the first telescopic tube 11 and the second telescopic tube 12 mentioned above are retracted, the cleaning component 4 includes a rotating rod 41 rotatably connected to the center of the filter screen 13. A cleaning brush 42 is fixedly attached to the outer periphery of the front end of the rotating rod 41, and the brush surface of the cleaning brush 42 is movably attached to the surface of the filter screen 13. The rear end of the rotating rod 41 extends into the interior of the suction head 1 and is fixedly connected to a transmission column 43, which is connected to the inner wall of the suction head 1. The transmission column 43 is perpendicular to the rotating rod 41, and one end of the transmission column 43 away from the rotating rod 41 is movably engaged in a spiral groove 44 opened in the inner wall of the suction head 1.

[0052] The filter screen 13 is designed to filter and intercept small bone and soft tissue debris generated at the opening during spinal surgery. When the first telescopic tube 11 and the second telescopic tube 12 retract, the end of the transmission column 43 connected to the rear end of the rotating rod 41 that is away from the rotating rod 41 slides along the inner wall of the spiral groove 44. This allows the cleaning brush 42 to rotate via the rotating rod 41 during retraction, thereby removing debris adsorbed on the surface of the filter screen 13. This prevents the first and second telescopic tubes 11 and 12 from being obstructed by adsorption when they extend forward again to suck blood. The end of the transmission column 43 that is away from the rotating rod 41 is rounded, and the inner wall surface of the spiral groove 44 is also rounded to reduce the coefficient of friction of the transmission column 43 sliding in the spiral groove 44.

[0053] The workflow of the technical solution provided by this invention is as follows:

[0054] The operating physician manually operates the two traction plates 23, and in conjunction with the two first weakening grooves 22, pulls open the opening of the spinal surgery site through the hooks 24. Then, through the setting of the splint 26 and the universal flexible shaft 25, the suction head 1 is connected to the splint 26, so that the suction head 1 can be fixed in position during local traction.

[0055] Then, especially when suctioning blood from the deep, delicate structures of the spine, the compression sleeve 38 can be manually moved forward to slide forward on the two guide seats 381. This causes the compression sleeve 38 to compress the strip-shaped airbag 37 through the compression ramp 39, allowing air in the strip-shaped airbag 37 to be delivered to the first air intake chamber 31 through the Z-shaped air intake channel 36. This pushes the first telescopic tube 11 forward, and simultaneously, multiple first return springs 34 are compressed and deformed. At the same time, the first telescopic tube 11 is stopped by the blocking sleeve 316 after extending a certain length, thus ensuring the extension length of the first telescopic tube 11. If the first telescopic tube 11 cannot extend forward further, the compression sleeve 38 will compress the strip-shaped airbag 37 as it continues to move forward. This causes the air in the strip-shaped airbag 37 to enter the second air intake chamber 32 through multiple air inlets 310, which pushes the second telescopic tube 12 forward. At the same time, multiple second return springs 35 are compressed and deformed, so that the suction head 1 can achieve the purpose of step-by-step extension and retraction. This allows for the extension of a smaller diameter second telescopic tube 12 to target deep structures such as the spinal canal, enabling more precise blood suction and avoiding the need for secondary positioning of the field of vision, which would affect the surgical process.

[0056] After blood suction from the delicate structural area, if the surgeon needs to perform a second operation on the wound, the first telescopic tube 11 and the second telescopic tube 12 need to retract to allow the surgeon to reserve the surgical field. The squeezing sleeve 38 can be manually moved from front to back, so that the squeezing sleeve 38 no longer squeezes the strip-shaped airbag 37. Under the action of the first return spring 34 and the second return spring 35, the air in the first air intake chamber 31 and the second air intake chamber 32 is drawn back into the strip-shaped airbag 37. At the same time, the end of the transmission column 43 connected to the rear end of the rotating rod 41, away from the rotating rod 41, will slide along the inner wall of the spiral groove 44. During the retraction process, the cleaning brush 42 will rotate through the rotating rod 41, so that the debris adsorbed on the surface of the filter screen 13 can be removed when it retracts, so as to avoid the first telescopic tube 11 and the second telescopic tube 12 being obstructed by adsorption when they extend forward again to suction blood, which plays a good role in preventing blockage.
