Description

TECHNICAL FIELD

[0001] The utility model relates to a dilator, concretely is a gynecological examination dilator of improving comfortable feeling belongs to medical instrument technical field. BACKGROUND

[0002] The gynecological examination dilator (also called speculum, duck mouth instrument) is an important instrument for opening the vaginal wall, exposing the cervix and vagina in gynecological examination. Its traditional design has not been fundamentally changed since its invention, and the "duck mouth type" structure composed of two metal or hard plastic blades is widely used, and the opening and closing are mechanically linked through external handles or knobs. However, this traditional design brings significant physiological and psychological discomfort to patients in actual clinical application, which has become a key problem affecting examination compliance and medical quality.

[0003] In the prior art, such as the one disclosed in the utility model with the announcement number CN219353869U, the gynecological examination dilator is provided with a dilator body and a movable piece. In the physiological aspect, the cold feeling of metal material at room temperature will cause strong discomfort when contacting the warm mucosa; its hard surface directly rubs with dry tissue in a tense state, which is easy to cause pain; more importantly, the one-piece linkage design of the two-leaf type causes the dilating action to be a direct and synchronous violent opening, lacking a buffering and gradual process, and the instantaneous pulling force will excessively stimulate the tissue. Secondly, in the structural function aspect, the traditional design often ignores the continuous lubrication demand in the use process, and the preoperative lubricant is easy to be wiped off and unevenly distributed. In addition, the one disclosed in the utility model with the announcement number CN219353869U, although it realizes multi-angle fixation through the clamping structure, its core is still the rigid linkage dilating of the two pieces, and it does not solve the fundamental problem of the above-mentioned pain and discomfort. Furthermore, the shame and fear psychology of patients caused by exposure will intensify the defensive tension of the pelvic floor muscles, forming a vicious cycle of "the tighter, the more painful". Although some researches have begun to focus on improving the touch feeling and pressure distribution by using flexible materials (such as medical silicone rubber), most of them still stay at the level of material substitution or simple inflation type dilating, and they cannot systematically optimize the overall mechanical structure, dilating dynamics and real-time auxiliary function to simultaneously cope with the physiological and psychological challenges. Therefore, there is an urgent need in the clinic for a gynecological examination dilator that can comprehensively improve the comfort of patients in terms of material touch feeling, dilating mechanism, lubrication method and privacy protection.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the utility model.

[0033] Embodiment one

[0034] As Figures 1 to 11The gynecological examination dilator shown in the application comprises an outer support ring 1 and a plurality of dilating leaves 2 arranged in the ring. The dilating leaves 2 comprise a front leaf body 22, a middle leaf body 21 and a tail leaf body 24 connected in sequence. The outer support ring 1 is located outside the end of the middle leaf body 21 close to the tail leaf body 24. An independently arranged dilating control assembly 3 is connected between the middle leaf body 21 of each dilating leaf 2 and the outer support ring 1. The plurality of dilating leaves 2 are in a folded state in the initial state. This design makes the insertion cross section smaller and reduces the initial invasion. The dilating control assembly 3 arranged provides an independent movement fulcrum and driving source for each dilating leaf 2 through the outer support ring 1, so that the doctor can control the expansion of a single or multiple dilating leaves 2 step by step and to different degrees as needed, realize progressive expansion from the center to the periphery or in different areas, avoid the instantaneous strong pulling pain caused by the violent expansion of the traditional two-leaf instrument at the same time, give the tissue more sufficient adaptation time, and improve the control accuracy and patient tolerance of the expansion process.

[0035] The front leaf body 22 is inwardly bent, and the tail leaf body 24 is outwardly bent. The outer side of the front leaf body 22 arranged on the examination site of the patient is provided with a micropore area 26, and the micropore area 26 is in communication with an external syringe containing a sterile lubricant or anesthetic gel. The outer layer of each leaf body of the dilating leaf 2 is provided with a warm soft material layer 27. It should be noted that the warm soft material layer 27 can be made of medical-grade silicone, TPE or other high-molecular polymers sensitive to human body temperature. The inward bending of the front leaf body 22 makes it smoother to guide into the cavity of the patient and reduces the direct pressure on the sensitive tissues at the front end of the cavity. The outward bending of the tail leaf body 24 does not block the doctor's line of sight. By connecting the external syringe with the micropore area 26 at the working front end, lubricant or anesthetic gel can be delivered to the contact surface between the dilating leaf 2 and the examination site at any time during the examination, overcoming the defect that the traditional preoperative surface smearing of lubricant is easy to be wiped off and unevenly covered. If anesthetic is used, rapid local analgesia can be achieved, reducing the friction pain and reflex muscle spasm caused by dry or sensitive tissues in patients. The warm soft material layer 27 makes the dilating leaf 2 maintain appropriate rigidity for operation at room temperature, but softens rapidly once it comes into contact with warm human tissues, giving it a soft and elastic quality close to human tissues, eliminating the strong stimulation and fear association caused by the cold and hard touch of metal instruments.

[0036] The expansion control assembly 3 comprises a threaded rotating rod 31 and an elastic telescopic rod 34. One end of the threaded rotating rod 31 is movably connected to the middle section blade body 21, and the rod body of the threaded rotating rod 31 is threaded through the outer support ring 1. The elastic telescopic rod 34 is fixedly connected to the inner side of the ring body of the outer support ring 1. The elastic telescopic rod 34 is in a partially contracted state when the expansion blade 2 is in an expanded state. The end of the middle section blade body 21 close to the front section blade body 22 is in an outwardly inclined state when the expansion blade 2 is in an expanded state. In the expansion process, the elastic telescopic rod 34 is compressed to accumulate elastic force, not only absorbing part of the expansion kinetic energy to make the action more gentle, but also responding elastically to the tissue pressure to dynamically adjust the support force. When the middle section blade body 21 moves to contact the elastic telescopic rod 34 under the driving of the threaded rotating rod 31, the connection point of the threaded rotating rod 31 and the middle section blade body 21 becomes a fulcrum. The elastic resistance of the elastic telescopic rod 34 to the middle section blade body 21 promotes the front end of the middle section blade body 21 to continue to expand outwardly inclined around the fulcrum, ensuring that the expansion blade 2 can deeply enter the patient's cavity to achieve full expansion. At the same time, due to the inclined movement, the transverse opening force of the examination port is effectively controlled, avoiding excessive pulling on sensitive entrance tissues, and the expansion force is more concentrated on the internal area to be examined. It should be noted that the elastic telescopic rod 34 can adopt the telescopic rod in the telescopic rod with elastic damping structure disclosed in CN118532381A.

[0037] Example two

[0038] Based on the improvement of example one:

[0039] As shown in Figures 1 to 11 , the ring body of the outer support ring 1 is connected with a plurality of threaded sleeves 11 corresponding to the threaded rotating rod 31. The rod body of the threaded rotating rod 31 is threadedly connected in the threaded sleeve 11. When the threaded rotating rod 31 is rotated, the driving force can be transmitted to the outer support ring 1 through the threaded sleeve 11, thereby being converted into a linear or rotational traction force on the middle section blade body 21, avoiding shaking or deviation in the transmission process, and enhancing the stability of the expansion blade 2 during expansion.

[0040] Further, the outer side surface of the middle blade body 21 is fixedly connected with a butt joint lug 38, the end of the threaded rotating rod 31 close to the middle blade body 21 is rotatably connected with a butt joint seat 37, the butt joint seat 37 is rotatably connected with the butt joint lug 38, and the rotating direction of the butt joint seat 37 and the butt joint lug 38 is consistent with the tilting direction of the expansion blade 2 when expanding, the end of the threaded rotating rod 31 located outside the outer support ring 1 is fixedly connected with a rotating knob 35, the rod body of the threaded rotating rod 31 between the middle blade body 21 and the outer support ring 1 is sleeved with a spring 33, the rotating connection of the butt joint lug 38 and the butt joint seat 37 is consistent with the tilting direction of the expansion blade 2 when expanding, which provides a matching degree of freedom for the swinging of the expansion blade 2, the rotating knob 35 enables the doctor to perform fine adjustment operation, and the spring 33 sleeved on the rod body of the threaded rotating rod 31 stores elastic potential energy in the compressed state, the pressure of the spring 33 can be used as auxiliary force or buffer force to be overcome when the expansion blade 2 is positively expanded, so that the expansion process is more moderate; when the expansion blade 2 needs to be folded, the restoring force released by the spring 33 can assist the expansion blade 2 to stably fold.

[0041] Further, the expansion control assembly 3 further comprises a limiting rod 32, the limiting rod 32 is provided in one-to-one correspondence with the threaded rotating rod 31, one end of the limiting rod 32 is connected with the middle blade body 21, the ring body of the outer support ring 1 is provided with a plurality of positioning through holes 12, the rod body of the limiting rod 32 is movably penetrated through the positioning through holes 12, the limiting rod 32 can limit the radial swinging or rotation of the expansion blade 2 in the expansion process due to the non-uniform pressure of the tissue, and ensure that the expansion blade 2 can move along a stable track.

[0042] Further, the outer side surface of the middle blade body 21 is fixedly connected with a rubber base 39, one end of the limiting rod 32 close to the middle blade body 21 is fixedly connected on the rubber base 39, one end of the limiting rod 32 outside the outer support ring 1 is fixedly connected with a limiting block 310, the rubber base 39 can absorb and dampen the slight impact and vibration generated by the expansion movement or the tissue reaction force, prevent these forces from being directly and rigidly transmitted to the middle blade body 21 and the limiting rod 32, and at the same time, the rubber base 39 can also provide a certain deformation compensation, allow a slight alignment deviation, and ensure that the middle blade body 21 can tilt the blade body when expanding, and the limiting block 310 can prevent the limiting rod 32 from being pulled out of the positioning through holes 12 of the outer support ring 1.

[0043] Further, the telescopic top end of the elastic telescopic rod 34 is embedded with a ball 36, when the expansion blade 2 is in the expanded state, the ball 36 is tightly attached to the outer side surface of the middle blade body 21, the ball 36 changes the original sliding friction into rolling friction, so that the frictional resistance of the elastic telescopic rod 34 is extremely small when it is adjusted in extension and contraction along with the movement of the expansion blade 2, and the rolling characteristics of the ball 36 can also avoid scratching and damaging the temperature sensing soft material layer 27 on the surface of the expansion blade 2.

[0044] As shown in Figures 1 to 6 and Figure 11 Each segment of the expansion leaf 2 further comprises a metal blade 28 located in the inner layer, the front end of the front segment leaf 22 is provided with a biomimetic conical arc surface 23, and the warm soft material layer 27 is tightly wrapped outside the metal blade 28, which can provide a soft touch to the patient, and relieve physiological discomfort when in contact. The shape of the biomimetic conical arc surface 23 is more in line with the natural form of the human anatomy channel, which can enter more smoothly when inserted, reducing the compression and pulling sensation on the examination port and the initial segment of the tissue.

[0045] Further, the micropore area 26 is opened on the warm soft material layer 27, the metal blade 28 of the front segment leaf 22 is provided with a liquid guide groove 211 at a position inside the micropore area 26, the metal blade 28 of the middle segment leaf 21 and the metal blade 28 of the tail segment leaf 24 are both provided with a concave tube groove 210, a liquid guide tube 29 is arranged in the tube groove 210, the outer side of the middle segment leaf 21 close to the tail segment leaf 24 is further fixedly connected with a liquid inlet connector 25, one end of the liquid guide tube 29 is in communication with the liquid inlet connector 25, and the other end of the liquid guide tube 29 is in communication with the liquid guide groove 211. The micropore area 26 is opened on the warm soft material layer 27, which can ensure that the liquid medicine is directly exuded to the surface in contact with the tissue, the liquid guide groove 211 constitutes a local fluid distribution cavity, which is helpful to the uniform distribution of the lubricant before the outlet end, the liquid guide tube 29 arranged in the tube groove 210 and the liquid inlet connector 25 form a delivery channel, so that the doctor can deliver the warm sterile lubricant or anesthetic gel directly into the inner wall of the patient's examination site before or during the examination by connecting a syringe.

[0046] Further, the outer support ring 1 is detachably sleeved with a cover 4, and the cover 4 is shielded outside the examination site of the patient when the expander is used. The cover 4 can establish a visual barrier between the operation field of view of the doctor and the privacy area of the patient, protecting the personal privacy of the patient.

[0047] Working principle: Before use, the plurality of expansion leaves 2 are in a retracted state, after insertion, the warm soft material layer 27 wrapped outside each segment of the leaf is gradually softened under the action of body temperature, providing a warm and soft contact interface, when the expansion operation is needed, the doctor can operate each independently arranged expansion control assembly 3, rotate the rotating knob 35 at one end of the threaded rotating rod 31, drive the threaded rotating rod 31 to move linearly, and transmit the linear motion to the middle segment leaf 21 to drive it to start moving;

[0048] In the initial moving stage, the middle section blade body 21 mainly performs translation, and as it moves outward, its outer side gradually approaches and contacts the top end of the elastic telescopic rod 34 fixed to the inner side of the outer support ring 1; thereafter, the threaded rotating rod 31 continues to rotate, the telescopic end of the elastic telescopic rod 34 keeps in contact with the outer side of the middle section blade body 21 and starts to be compressed, generating elastic resistance, at this time, the connecting point of the threaded rotating rod 31 and the middle section blade body 21 becomes a rotation support point in essence, under the joint action of the continuous thrust of the threaded rotating rod 31 and the elastic resistance of the elastic telescopic rod 34, the movement mode of the middle section blade body 21 changes from translation to inclined rotation based on the above-mentioned support point as the shaft, the end of the middle section blade body 21 close to the front section blade body 22 expands in an outwardly inclined manner, this process makes the overall shape of the expanding leaf 2 change from the folded shape to the inclined and open shape, and the front section blade body 22 gently props open the inner wall tissue of the examination site, due to the inclined expanding characteristic, the expanding force is more focused on fully expanding the deep part of the inner cavity, and the transverse prop opening force on the examination port part is effectively buffered and limited, in cooperation with the continuous elastic support provided by the elastic telescopic rod 34, the gradual, controllable and stress-distributed expanding effect is realized, and the tissue pulling pain is significantly reduced.

[0049] If additional lubrication or local anesthesia is needed during the examination process, the doctor can connect the external injector to the liquid inlet connector 25, deliver the sterile lubricant or anesthetic gel through the liquid guide pipe 29 to the liquid guide groove 211 at the front section blade body 22, and finally uniformly seep out from the micropore area 26 on the outer side of the front section blade body 22 to directly act on the interface between the expanding leaf 2 and the tissue in contact, so as to realize active and targeted lubrication or analgesia and further reduce friction discomfort.
