Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a multifunctional speculum for collecting tissue. Background Technology

[0002] A speculum is an essential instrument for gynecological hysteroscopy and curettage, used to dilate the vagina, expose the cervix, and provide an operating channel and surgical field for intrauterine procedures. Currently, the traditional speculum routinely used in clinical practice mainly consists of upper and lower blades, a hinged structure, and adjustment components. It can only achieve vaginal dilation and angle fixation, and has significant limitations in hysteroscopy and curettage procedures.

[0003] The procedure generates a large amount of blood, irrigation fluid, and specimens such as endometrium and diseased tissue. Traditional speculum lacks tissue collection and fluid drainage structures, and detached tissue easily mixes with the fluid and scatters in the vagina, resulting in tissue specimen loss, incomplete sampling, and affecting the accuracy of pathological diagnosis. Furthermore, the adjustment and locking between the upper and lower blades of the existing speculum requires a nut, which is time-consuming to rotate. In addition, after the surgical instruments are inserted through the operating channel between the upper and lower blades, medical staff need to hold them by hand for a long time, making the procedure inconvenient.

[0004] Therefore, it is necessary to make further improvements to the existing technology. Summary of the Invention

[0043] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention: a multifunctional speculum capable of collecting tissue.

[0044] Reference Figures 1 to 10 As shown, a multifunctional speculum for collecting tissue according to an embodiment of the present invention includes an upper blade 10, a lower blade 20, a filter 21, a drainage tube 23, a locking assembly 30, and a clamping assembly 40.

[0045] The lower blade 20 and the upper blade 10 are arranged opposite each other, and their tail ends are hinged to each other by a pivot, so that the upper blade 10 and the lower blade 20 can be adjusted by the hinge position.

[0046] The lower blade 20 has a groove 22 on its inner bottom surface, and the filter screen 21 is installed in the groove 22 to filter liquid and collect tissue.

[0047] One end of the drainage tube 23 is connected to the groove 22, and the other end is connected to a drainage device to draw out the liquid that has entered the groove 22.

[0048] The locking assembly 30 is connected to the tail ends of the upper blade 10 and the lower blade 20, and can automatically lock the positions of the upper blade 10 and the lower blade 20 after the upper blade 10 and the lower blade 20 have been opened and adjusted.

[0049] One end of the clamping assembly 40 is detachably connected to the tail end of the lower blade 20, and the other end of the clamping assembly 40 is adapted to clamp surgical instruments.

[0050] Based on the above, by setting a filter 21 in the groove 22 of the lower blade 20, intraoperative blood and irrigation fluid can be effectively filtered, and specimens such as endometrial tissue and lesions can be retained, avoiding tissue loss and ensuring specimen integrity. The drainage tube 23 is connected to the groove 22, which can promptly drain the fluid generated during the operation, reduce vaginal fluid accumulation, avoid blurred vision, reduce repeated wiping and suction operations during the operation, and improve surgical efficiency. The locking component 30 can automatically lock after the upper blade 10 and lower blade 20 are opened and adjusted to the correct position, without the need for manual tightening of nuts, saving adjustment time, reducing operational complexity, and improving the ease of use of instruments. At the same time, the detachable clamping component 40 can stably clamp surgical instruments, eliminating the need for medical staff to hold them by hand for a long time, relieving operational fatigue, improving instrument operation stability, and ensuring smooth operation.

[0051] Preferably, in one embodiment of the present invention, the tail end of the lower blade 20 is connected to a downwardly extending gripping part 24 for hand gripping, the side wall of the gripping part 24 is provided with a tube placement groove 241, the tube placement groove 241 extends along the length direction of the gripping part 24, and the drainage tube 23 is fitted into the tube placement groove 241.

[0052] Thus, by providing a downward-extending gripping part 24 at the tail end of the lower blade 20, a comfortable and stable gripping point is provided for medical staff, which facilitates precise control of the position and angle of the speculum during the operation. Furthermore, a tube insertion groove 241 extending along the length direction is provided on the side wall of the gripping part 24, which allows the drainage tube 23 to be fitted and embedded in the groove, thereby achieving orderly storage and fixation of the drainage tube 23 and preventing the drainage tube 23 from shaking or getting tangled.

[0053] Preferably, in one embodiment of the present invention, the filter screen 21 is inclined downward from front to back along the length direction of the lower blade 20.

[0054] Thus, the filter 21 is inclined downwards from front to back, allowing gravity to cause tissue specimens detached during surgery to naturally gather towards the rear end of the filter 21 (near the tail end of the lower blade 20) under the flushing effect of liquid. This prevents tissue specimens from being dispersed and remaining on the filter 21, further ensuring the integrity of tissue specimen collection and providing reliable support for pathological diagnosis. Advantageously, the bottom surface of the groove 22 can also be set in the same inclined shape as the filter 21, thereby preventing blood and other liquids from remaining in the groove 22.

[0055] As a preferred embodiment of the present invention, the front end of the filter screen 21 can form an insertion structure with the front side of the groove portion 22, and the rear end face of the filter screen 21 can be provided with a compression spring, so that the rear end of the filter screen 21 is fixed in the groove portion 22 by the compression spring, thereby making the filter screen 21 stably installed and quickly disassembled.

[0056] As a preferred embodiment of the invention, the filter 21 is provided with upwardly extending enclosure portions on the left and right sides and the rear end, and a top enclosure portion is provided above the enclosure portions, so that the tissue specimens are more stably accumulated in the area defined by the enclosure portions and the top enclosure portions.

[0057] Preferably, in one embodiment of the present invention, the upper blade 10 is provided with downwardly extending first extension pieces 11 on both sides of its tail end, and the lower blade 20 is provided with upwardly extending second extension pieces 25 on both sides of its tail end, the two first extension pieces 11 and the two second extension pieces 25 corresponding to each other and pivotally connected.

[0058] Thus, since the first extension plates 11 on both sides of the tail end of the upper blade 10 and the second extension plates 25 on both sides of the tail end of the lower blade 20 are pivotally connected in a one-to-one correspondence, a double-sided symmetrical hinge structure is formed, making the connection between the upper blade 10 and the lower blade 20 more stable and more conducive to pivoting operation.

[0059] Preferably, in one embodiment of the present invention, the locking assembly 30 includes an adjusting plate 31, a mounting post 32, a locking post 33, and a torsion spring 34.

[0060] The adjustment piece 31 is located outside one of the first extension pieces 11, so that the upper blade 10 and the lower blade 20 can be opened by pressing the lower end of the adjustment piece 31. The adjustment piece 31 is provided with a through groove 311, which extends along the length direction of the adjustment piece 31.

[0061] The mounting post 32 is located on the outside of one of the second extension pieces 25.

[0062] One end of the locking pin 33 is sleeved on the mounting pin 32, allowing the locking pin 33 to rotate along the axis of the mounting pin 32. The other end of the locking pin 33 passes through the through groove 311. The mounting pin 32 and the adjusting piece 31 are located on the same side.

[0063] The torsion spring 34 is sleeved on the mounting post 32. One end of the torsion spring 34 is connected to the locking post 33, and the other end is connected to the second extension piece 25.

[0064] The locking pin 33 has a rack 35 on its bottom surface, and the teeth on the rack 35 extend obliquely toward one end of the locking pin 33. The bottom of the through groove 311 has a retaining part 312, which is adapted to be engaged between two adjacent teeth to achieve one-way locking.

[0065] Thus, through the matching engagement structure between the rack 35 and the retaining part 312, and with the continuous elastic preload provided by the torsion spring 34, the locking state can be ensured to remain stable, preventing loosening of the lock due to instrument shaking or operational collisions during surgery, avoiding accidental closure or displacement of the upper and lower blades 20, and ensuring a stable surgical field and operational safety. In use, medical personnel only need to press the lower end of the adjusting piece 31 to drive the upper blade 10 to pivot upwards, causing the lower blade 20 and the upper blade 10 to open. The teeth on the rack 35 extend obliquely towards one end of the locking post 33, at the upper blade 10... When the upper blade 10 and lower blade 20 are opened, the rack 35 will slide off the retaining part 312 (the force generated by pressing will cause the rack 35 and locking post 33 to pivot upward). After the upper blade 10 and lower blade 20 are adjusted, the pressing force on the adjusting piece 31 is released. At this time, the retaining part 312 will fit between two adjacent teeth and be held in the current retaining state by the elastic force of the torsion spring 34 to achieve one-way locking. This eliminates the need to manually tighten the nut, simplifies the locking operation, saves surgical time, improves the ease of use of the instrument, and meets the needs of rapid adjustment and fixation during surgery.

[0066] Correspondingly, when unlocking is required, simply press down on the adjusting piece 31 and push the locking pin 33 upward to unlock.

[0067] Preferably, in one embodiment of the present invention, the clamping assembly 40 includes a horizontal column 41, two telescopic columns 42, a connector 44, and a clamping member 45.

[0068] The horizontal column 41 has a hollow structure.

[0069] The two telescopic columns 42 are telescopically inserted through both ends of the horizontal column 41, and a return spring 43 is provided between the two telescopic columns 42.

[0070] One end of the connector 44 is located on the outer surface of the horizontal column 41.

[0071] The clamping member 45 is located at the other end of the connector 44 and is used to clamp surgical instruments.

[0072] The two second extension pieces 25 are provided with a plurality of vertically spaced insertion holes 251, and the insertion holes 251 on the two second extension pieces 25 are arranged one-to-one. The ends of the two telescopic columns 42 are respectively inserted into the insertion holes 251 of the two second extension pieces 25.

[0073] Thus, by engaging the telescopic column 42 with the insertion hole 251 of the second extension plate 25, the clamping component 40 and the lower blade 20 can be quickly installed and disassembled without additional tools. This facilitates the disassembly, disinfection, and maintenance of instruments postoperatively. Furthermore, the clamping component 40 can be selected for installation based on surgical needs, adapting to different surgical scenarios and enhancing practicality. Under the elastic action of the return spring 43, the two telescopic columns 42 can be tightly inserted into the corresponding insertion hole 251, forming a stable locking structure to prevent the clamping component 40 from loosening or falling off during surgery, ensuring the stability of the clamped surgical instruments. Simultaneously, the second extension plate 25 has multiple vertically spaced, one-to-one corresponding insertion holes 251. By inserting the telescopic column 42 into insertion holes 251 at different heights, the height of the clamping component 40 and the clamped surgical instruments can be flexibly adjusted to adapt to different surgical field requirements, improving the instrument's versatility and operational flexibility.

[0074] Preferably, in one embodiment of the present invention, the surface of the horizontal column 41 is provided with a through groove 411, the through groove 411 extends along the length direction of the horizontal column 41, and the ends of the two telescopic columns 42 are provided with a pushing part 421, the two pushing parts 421 extend through the through groove 411 to the outside of the horizontal column 41, so as to push the two telescopic columns 42 to perform telescopic adjustment through the pushing part 421.

[0075] Thus, a through groove 411 is provided on the surface of the horizontal column 41 along its length direction. The pushing part 421 extends to the outside through the through groove 411. Medical staff can directly use their fingers to simultaneously move the pushing part 421 (i.e., pinch or release both pushing parts 421) to quickly drive the two telescopic columns 42 to extend and retract synchronously without the need for additional tools. This simple and labor-saving operation greatly improves the efficiency of installing, disassembling, and adjusting the height of the clamping assembly 40, meeting the needs of rapid operation during surgery. At the same time, since the pushing part 421 passes through the through groove 411, it limits the telescopic column 42, restricting its movement to only along the length direction of the horizontal column 41, preventing accidental movement of the clamping member 45.

[0076] Preferably, in one embodiment of the present invention, each of the two second extension pieces 25 has a plurality of first protrusion groups on its opposite sides, each of the first protrusion groups being composed of a plurality of first protrusion portions 252, the plurality of first protrusion groups being disposed one-to-one on the outer edge of the plurality of insertion holes 251, and the plurality of first protrusion portions 252 being distributed circumferentially at intervals along the insertion holes 251.

[0077] Both of the telescopic columns 42 are provided with extrusion plates 46 on their outer surfaces. The extrusion plates 46 extend circumferentially along the telescopic column 42 and are opposite to the inner side of the second extension plate 25. Both of the extrusion plates 46 are provided with a second protrusion group on their opposite sides. The second protrusion group is composed of a plurality of second protrusions 461, and the plurality of second protrusions 461 and the plurality of first protrusions 252 are staggered and interlocked.

[0078] Thus, the first protrusion group is located on the outer edge of the insertion hole 251, and the second protrusion group is located on the compression piece 46. The two are staggered and interlocked to form an interlocking structure. With the preload of the return spring 43, the entire clamping assembly 40 is stably held in the current position. It should be noted that both sides of the first protrusion 252 and the second protrusion 461 form arc-shaped surfaces. When medical personnel rotate the entire clamping assembly 40 with a large force, the first protrusion 252 and the second protrusion 461 are squeezed. The squeezing force can push the two telescopic columns 42 to retract towards the middle of the horizontal column 41, thereby realizing the smooth rotation of the entire clamping assembly 40. After the multiple second protrusions 461 move to one position in sequence, the elastic force of the return spring 43 pushes the telescopic columns 42 to return to the next insertion and locking position. Through the above steps, the position of the clamping assembly 40 can be adjusted as needed to meet the usage requirements.

[0079] Preferably, in one embodiment of the present invention, the clamping member 45 is constructed in a "U" shape. Of course, the U-shaped structure is one of the structures proposed in this patent, and other structural shapes can be set according to needs in practical applications. A receiving gap 451 for accommodating surgical instruments is constructed in its middle. The side of the clamping member 45 is provided with a locking screw 452, the end of which extends into the receiving gap 451 to fix the surgical instruments placed in the receiving gap 451.

[0080] Thus, the accommodating gap 451 constructed by the "U"-shaped clamp 45 can flexibly accommodate gynecological surgical instruments of different diameters and types (such as hysteroscopes, curettage forceps, etc.) without the need to replace the dedicated clamp 45, adapting to various surgical scenarios and reducing the cost of clinical instruments. By tightening the locking screw 452, its end can tightly abut against the surface of the surgical instrument within the accommodating gap 451, achieving a firm fixation of the surgical instrument, preventing the instrument from sliding or shifting during the operation, ensuring the accuracy of the surgical operation, and avoiding tissue damage caused by instrument shaking.

[0081] Advantageously, in another embodiment of the invention, the clamping member 45 and the connecting member 44 are configured as a detachable structure, so that different clamping members can be replaced as needed during specific use.

[0082] Preferably, in one embodiment of the present invention, the connector 44 is a gooseneck tube.

[0083] Thus, the gooseneck tube has the characteristics of being able to bend and shape at will, which can drive the clamping part 45 and the surgical instruments it holds to flexibly adjust the angle and position, accurately adapt to different surgical field requirements, and facilitate medical staff to adjust the operating posture of surgical instruments. Together with the rotatable horizontal column part 41, it effectively improves the flexibility and convenience of surgical operation.
