Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a foreign body forceps structure for assisting in removing an IUD under B-ultrasound. Background Art

[0002] In the field of gynecology, the removal of intrauterine contraceptive rings (IUDs) is a common clinical need in menopausal patients. Traditionally, ultrasound-assisted IUD removal is often limited by various factors, making it difficult for doctors to accurately locate the IUD, increasing the difficulty and risk of IUD removal. Furthermore, prolonged placement of IUDs in the uterine cavity can easily cause adhesions to surrounding tissue, further complicating removal. When excessive adhesions are present, ultrasound images are extremely complex, with numerous overlapping adhesions making it difficult to discern the IUD's outline and position. Doctors are unable to obtain clear and accurate information from ultrasound images to plan the IUD removal procedure. Moreover, for difficult adhesion tissues, such as tight and tough adhesions caused by inflammation, B-ultrasound is even more powerless. It cannot clearly show the boundaries between the adhesion tissue and the contraceptive ring and the uterine wall, and it is difficult to determine the depth and range of the adhesion. Once the above-mentioned complex adhesion conditions occur, it is almost impossible to complete the ring removal operation with the assistance of B-ultrasound alone. At this time, the patient often needs to be transferred from the obstetrics and gynecology department to the hysteroscopy department for hysteroscopy to remove the ring. This is not only cumbersome, but also consumes a lot of patients' time and energy, increases the psychological burden, and increases hospital management costs and reduces medical efficiency. Ordinary ring removal instruments are seriously insufficient in dealing with such complex adhesion tissues and are difficult to separate efficiently. During the operation, it is easy to damage the uterus, causing serious complications such as perforation and heavy bleeding, which seriously threaten the patient's health. If the patient is transferred to the hysteroscopy department for hysteroscopy to remove the ring, it will not only increase the patient's psychological burden, but also increase the patient's medical costs. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the present invention provides a foreign body forceps structure for assisting the removal of an IUD under B-ultrasound, in order to solve the problem that the traditional IUD cannot be removed with the assistance of B-ultrasound when there is too much adhesion tissue.

[0004] In order to achieve the above-mentioned purpose, the present invention provides a foreign body forceps structure for assisting in the removal of an intrauterine device under B-ultrasound, comprising an insertion tube for insertion into an external patient's body and an operating forceps for operating the insertion tube outside the patient's body. The insertion tube is provided with an image component for generating and transmitting data to an external image processing device to generate an image inside the patient's body when the initial end of the insertion tube is inserted into the external patient's body. The outer peripheral wall of the insertion tube is provided with a connecting component for adaptively connecting different adhesion tissues in the patient's body or connecting with the intrauterine device in the patient's body, and a clamping component for clamping difficult-to-separate adhesion tissues.

[0005] The benefits of adopting the above technical solution are: under the initial guidance of B-ultrasound, the doctor carefully inserts the starting end of the insertion tube into the patient's body. During the insertion process, the imaging component starts working, generating relevant data inside the patient's body in real time, and transmitting the data to an external image processing device. The image processing device generates an image inside the patient's body based on the received data. The doctor understands the approximate position of the IUD and the condition of the surrounding tissues by observing the image; according to the situation displayed by the image, the doctor operates the insertion tube with the operating forceps, controls the connecting component to adaptively connect with different adhesion tissues in the patient's body, and if the position of the IUD is found, the connecting component can also be connected to the IUD. Through the action of the hooking piece, the adhesion tissue is initially separated, creating conditions for the subsequent ring removal operation; for some difficult-to-separate adhesion tissue, the doctor operates the clamping piece to clamp it, and the clamping piece clamps the adhesion tissue with appropriate force, making it easier to separate, further reducing the obstruction of the adhesion tissue to the ring removal; after the hooking piece and the clamping piece have processed the adhesion tissue, the adhesion of the contraceptive ring and the surrounding tissue is improved, and the doctor can control the insertion tube by operating the forceps to remove the contraceptive ring. During the ring removal process, the doctor continuously observes the images generated by the image processing equipment and the B-ultrasound image, and ensures the safety and accuracy of the ring removal operation through the combination of two different images.

[0006] In the above technology, the image component can generate and transmit data to an external image processing device when the beginning of the insertion tube is inserted into the patient's body, thereby generating an image of the patient's body. The generated in-body image is combined with the B-ultrasound image to overcome the problem of limited imaging when the traditional method of removing the ring with the assistance of B-ultrasound can be used. The doctor can use the image to more clearly and accurately locate the position of the contraceptive ring, provide a reliable basis for the removal operation, greatly improve the success rate of the ring removal operation, and reduce the surgical risk. In view of the complex situation that the contraceptive ring is easily adhered to the surrounding tissues after long-term placement in the uterine cavity, the hooking member on the outer wall of the insertion tube can adaptively hook to different adhesion tissues in the patient's body, and can also hook with the contraceptive ring. In this way, the adhesion tissue can be better separated, making the contraceptive ring easier to remove, avoiding the problem that the contour and position of the contraceptive ring are difficult to distinguish due to excessive and overlapping adhesion tissues. At the same time, the clamping member can clamp the difficult-to-separate adhesion tissue, further assist the separation operation, improve the surgical efficiency, and reduce the operation time. Since the foreign body clamp structure of the present invention can better cope with complex ring removal situations under B-ultrasound, it reduces the patient's risk of relying solely on B-ultrasound. In the case where super-assisted IUD removal surgery cannot be completed and the patient needs to be transferred from the obstetrics and gynecology department to the hysteroscopy department, this not only saves the patient a lot of time and energy and reduces the patient's psychological burden, but also avoids the increased medical costs due to transferring departments for IUD removal, and improves the patient's medical experience; traditional ordinary IUD removal instruments are insufficient in function when dealing with complex adhesion tissues, and are prone to damage to the uterus, causing serious complications such as perforation and heavy bleeding. The foreign body forceps structure of the present invention can more effectively separate adhesion tissues through the cooperation of the hooking part and the clamping part, and can be more accurately controlled during the operation, reducing unnecessary damage to the uterus, reducing the probability of serious complications, and better protecting the patient's health. Using the foreign body forceps structure of the present invention, most IUD removal surgeries can be completed directly in the obstetrics and gynecology department, reducing the situation of patients transferring departments, making the medical process smoother, and improving the hospital's medical efficiency. At the same time, it avoids the management complexity caused by patients transferring departments and reduces the hospital's management costs; in the above technology, the operating forceps are in the shape of a forceps body, and one end of the forceps can be connected to the insertion tube by threaded cooperation. It is an existing technology, so its structure and function will not be described in detail.

[0007] The present invention is further provided with: a swing groove is provided on the outer peripheral wall of the insertion tube along the length direction of the insertion tube, the swing groove is connected to the outer peripheral wall of the insertion tube and forms a swing opening, a synchronization plate is movably provided in the swing groove along the length direction of the insertion tube, the synchronization plate is provided with a cut groove along the length direction of the insertion tube, the inner walls on both sides of the cut groove are connected to the outer wall of the synchronization plate in a smooth curved surface and form a matching portion, the radial cross-section of the matching portion is an acute-angled triangle, a rotating shaft is connected between the inner walls on both sides of the cut groove, and the rotating shaft is arranged near the starting end of the synchronization plate, the clamping member includes a splint swingably set in the swing groove, the end of the splint is a swing end for the rotating shaft to pass through, and the starting end of the splint is used to swing out of the swing opening and connect with the outside patient's body The guide end is used to hook and cooperate with the adhesion tissue, the radial cross-section of the bottom wall of the splint is triangular and is formed with a cutting portion for cooperating with the cutting groove to cut the adhesion tissue when the splint is retracted to the swing groove, the operating forceps is provided with a pull rope for external medical personnel to pull to make the synchronous plate slide so that the splint can swing out of the swing mouth, and the outer peripheral wall of the insertion tube extends toward the swing mouth to cooperate with the outer wall of the splint when the synchronous plate slides toward the starting end of the insertion tube to retract the splint into the swing groove, and the swing groove is provided with a loading part for applying a force to the synchronous plate when the pull rope is not pulled so that the splint is restricted by the guide portion to retract to the swing groove and the cutting portion cooperates with the cooperating portion to achieve clamping of the adhesion tissue.

[0008] The above technical solution is beneficial in that: when it is necessary to treat adhesion tissue, the medical staff pulls the pull rope on the operating forceps, and the pull rope drives the synchronous plate to slide along the length direction of the insertion tube toward the end direction of the insertion tube. Due to the sliding of the synchronous plate, the swing end of the splint swings with the rotating shaft as the fulcrum, and the guide end of the splint gradually swings out of the swing opening to hook and cooperate with the adhesion tissue in the patient's body. The medical staff adjusts the splint according to B The ultrasound image or the image transmitted by the image piece is used to adjust the pulling degree of the pull rope so that the splint can accurately hook the adhesion tissue. When the splint hooks the adhesion tissue, the medical staff stops pulling the pull rope. At this time, the loader applies a force to the synchronization plate to make the synchronization plate slide toward the starting end of the insertion tube. During the sliding process of the synchronization plate, the guide part abuts and cooperates with the outer wall of the splint, forcing the splint to gradually retract into the swing groove. During the retraction process of the splint, the cutting part of the bottom wall of the splint interacts with the matching parts of the inner walls on both sides of the cutting groove to clamp the hooked adhesion tissue and prepare for cutting the adhesion tissue. As the splint continues to retract, the cutting part and the matching part cooperate more closely, and the clamped adhesion tissue is cut off by utilizing the shape and structural characteristics of the two. The medical staff can observe the cutting effect through B-ultrasound. If necessary, the above steps can be repeated to further process other adhesion tissues.

[0009] In the above technology, the unique structural design of the clamping part enables the splint to swing out of the swinging mouth to hook and cooperate with the adhesion tissue in the patient's body. It can achieve effective hooking for adhesion tissues in different positions and shapes. At the same time, when the splint retracts, the cooperation between the cutting part and the matching part can accurately cut off the adhesion tissue, greatly improving the processing efficiency of the adhesion tissue. Compared with traditional instruments, it can separate adhesions more quickly and effectively, creating good conditions for the smooth progress of the ring removal operation; the sliding of the synchronous plate is controlled by the pull rope on the operating forceps, thereby realizing the swing of the splint. This operation method is simple and flexible. Medical staff can accurately control the movement of the splint according to the actual surgical situation to meet different The needs of surgical scenarios, and when the pull rope is not pulled, the loader can make the splint retract to the swing groove under the restriction of the guide part, ensuring the safety and stability of the instrument when not in use, avoiding unnecessary damage to the patient; the triangular cutting part of the bottom wall of the splint in the above technology cooperates with the smooth curved matching parts of the inner walls on both sides of the cutting groove, which can reduce damage to the surrounding normal tissue when cutting the adhesion tissue, because this matching method can more accurately control the cutting position and force, reduce the risk of accidental damage to organs such as the uterus during surgery, ensure the safety of patients, and reduce the probability of serious complications such as perforation and heavy bleeding; the design of the above technology makes it easier for medical staff to handle adhesion tissue with the assistance of B-ultrasound, without complicated operating steps or replacing too many instruments, which simplifies the operating process of the ring removal surgery to a certain extent, saves operation time, reduces the workload of medical staff, and reduces the surgical pain of patients.

[0010] The present invention is further provided with: a loading cavity is hollowed out on the insertion tube, the loading cavity is connected to the swing groove and the end of the synchronous plate is slidably set in the loading cavity, the loading part includes a loading spring set in the loading cavity, the loading spring is a square spring, the loading spring is sleeved on the synchronous plate, the starting end of the loading spring is connected to the inner wall of the loading cavity, and the end of the loading spring is connected to the end of the synchronous plate.

[0011] The advantages of adopting the above technical solution are as follows: in the above technology, the loading spring is arranged in the loading cavity as a loading part and is sleeved on the synchronization plate, the starting end of which is connected to the inner peripheral wall of the loading cavity and the end end is connected to the end of the synchronization plate. When the pull rope is not pulled, the loading spring can continuously apply a stable force to the synchronization plate, ensuring that the splint is restricted by the guide part and retracts to the swing groove. That is, after the splint hooks the adhesion tissue, the operator can slowly loosen the pulling force on the pull rope, so that the pulling force on the pull rope gradually becomes less than the force applied to the synchronization plate by the elastic deformation of the loading spring. At this time, the loading spring drives the synchronization plate to slide, so that the splint is restricted by the guide part and gradually retracts into the swing groove until the cutting part cooperates with the cutting groove to cut and clamp the adhesion tissue, or after the splint hooks the adhesion tissue, the medical staff directly loosens the pull rope, so that the force generated by the elastic deformation of the loading spring instantly bursts out on the synchronization plate, thereby causing the synchronization plate to quickly slide back and drive the splint to swing, thereby cutting The square spring is not affected by the explosive impact force and cooperates with the cutting groove to achieve instant clamping and cutting of the adhesion tissue. The stable elastic restoring force of the loaded spring ensures that the splint can reliably return to its original position when not in use, avoiding accidental extension of the splint due to external interference and other factors, improving the safety and stability of the instrument during surgery, and reducing the risk of unnecessary damage to the patient's tissue; the structural design of the square spring in the above technology has certain advantages. Compared with the traditional circular spring, the deformation of the square spring when subjected to force is relatively more regular and stable, and can better adapt to different operating rhythms and force changes during surgery. During the operation, medical staff may pull and loosen the pull rope multiple times according to actual conditions to control the movement of the splint. The characteristics of the square spring enable it to maintain good elastic performance under repeated force, and continuously provide stable restoring force for the synchronization plate, ensuring that the splint can retract and extend in time and accurately, improving the fluency and efficiency of surgical operations.

[0012] The present invention further provides that: the outer wall of the cutting portion and the bottom wall of the cutting groove are uniformly provided with serrations along the length direction of the inserted tube.

[0013] The benefits of adopting the above technical solution are: in the above technology, serrations are evenly distributed on the outer wall of the cutting part and the bottom wall of the cutting groove, which greatly enhances the cutting ability of the adhesion tissue. When the splint retracts and the cutting part cooperates with the cutting groove, the serrations can be more effectively embedded in the adhesion tissue, increasing the contact area and friction with the adhesion tissue, making the cutting process smoother. Even for tough adhesion tissue, it can be cut more easily, improving the efficiency of handling adhesion tissue during surgery and reducing operation time; at the same time, the serrations evenly distributed along the length of the insertion tube can make the cutting force more evenly distributed on the adhesion tissue, avoiding tissue tearing or irregular cutting during the cutting process, thereby improving the cutting accuracy, helping to more accurately separate the adhesion tissue from the contraceptive ring or surrounding normal tissue, reducing accidental damage to normal tissue, reducing surgical risks, and ensuring the safety and reliability of the operation; since the adhesion tissue conditions of different patients may be different, the presence of serrations enables the structure to better adapt to various degrees and types of adhesions. Whether it is a loose adhesion or a tight and tough adhesion, the serrations can play their role. By effectively biting with the adhesion tissue, different adhesion tissues can be effectively cut off, which increases the versatility and adaptability of the foreign body forceps structure in clinical applications.

[0014] The present invention further provides that: guide grooves are provided on the inner walls on both sides of the swing groove along the length direction of the insertion tube, and the synchronous plates are provided with guide shafts toward the adjacent guide grooves, and the guide shafts are slidably provided in the corresponding guide grooves.

[0015] The benefit of adopting the above technical solution lies in the fact that the coordinated design of the guide slot and guide shaft provides precise guidance for the sliding movement of the synchronous plate within the swing slot. During operation, whether the medical staff pulls the pull cord to slide the synchronous plate toward the end of the insertion tube, or the loaded spring acts to retract the synchronous plate toward the beginning of the insertion tube, the sliding movement of the guide shaft within the guide slot ensures that the synchronous plate moves stably along the preset path, preventing the synchronous plate from shifting or shaking within the swing slot. This ensures that the splint can accurately swing and retract, improving the precision and reliability of the surgical operation.

[0016] The present invention further provides: a winding cavity is hollowed out in the operating pliers, the end of the pull rope passes through the end of the insertion tube and extends into the winding cavity, a winding shaft and a micro motor for driving the winding shaft to rotate axially are rotatably arranged in the winding cavity, and the end of the pull rope is wrapped around the winding shaft and connected to the winding shaft.

[0017] The benefits of adopting the above technical solution are: the above technology uses a micro motor to drive the winding shaft to rotate to retract and release the pull rope, which can achieve precise control of the pull rope tension. When dealing with adhesion tissue during ring removal surgery, medical staff can accurately adjust the tension of the pull rope by controlling the rotation angle and speed of the micro motor according to the actual situation, and then accurately control the swing amplitude and force of the splint, so that the clamping member can more accurately hook, clamp and cut the adhesion tissue, improving the accuracy and success rate of the surgical operation and reducing the risk of damage to the patient's normal tissue. Compared with the traditional manual pull rope method, which requires medical staff to continuously apply a certain amount of force, long-term operation can easily lead to hand fatigue, affecting the stability and accuracy of the operation. The present invention adopts a micro motor to drive the winding shaft. Medical staff only need to control the operation of the micro motor and do not need to manually pull the pull rope continuously. This greatly reduces the operating intensity of medical staff, allowing medical staff to observe the surgical conditions and perform other operations more attentively, thereby improving the safety and efficiency of the operation. The micro motor in the above technology is existing technology, so its structure and function will not be described in detail. The winding shaft and micro motor can be replaced with a micro reel according to actual usage requirements or installation requirements.

[0018] The present invention further provides that: the connecting member includes a plurality of connecting strips movably arranged on the insertion tube, and the plurality of connecting strips are evenly distributed circumferentially on the outer peripheral wall of the insertion tube and are arranged near the starting end of the insertion tube. The connecting strips are hook-shaped and the outer peripheral wall of the connecting strip and the inner peripheral wall of the connecting strip are connected by a smooth arc surface and have rounded corners.

[0019] The benefit of adopting the above technical solution is that: in the above technology, several hooking strips are evenly distributed on the outer peripheral wall of the insertion tube and are arranged near the starting position, so that the hooking piece can hook the adhesion tissue in the patient's body from multiple directions. During the surgical operation, when the insertion tube reaches the target position, the hooking strip can flexibly contact and hook with the surrounding adhesion tissue, which greatly increases the probability of hooking to the adhesion tissue, improves the efficiency of handling the adhesion tissue, helps to separate the adhesion more quickly, and creates favorable conditions for the subsequent ring removal operation. At the same time, the hooking strip is in the shape of a hook and a rounded corner is formed between the outer peripheral wall and the inner peripheral wall. This design can reduce damage to the surrounding normal tissue when hooking the adhesion tissue. The smooth arc surface of the rounded corner makes the hooking strip not as easy to scratch or puncture the normal tissue as sharp parts in the process of contacting and hooking the tissue, reducing the risk of accidental damage to organs such as the uterus during the operation, better ensuring the safety of the patient, and reducing the chance of postoperative complications.

[0020] The present invention is further provided with: a slot for accommodating a hooking strip is provided at each connecting strip position corresponding to the insertion tube; the connecting strip is made of a shape memory alloy; the connecting strip has a first form in a first temperature range; the connecting strip has a second form in a second temperature range; the connecting strip is arranged outside the slot in the first temperature range; the connecting strip is bent toward the slot in the second temperature range and is engaged with the slot; the shape of the slot is adapted to the shape of the connecting strip; a micro heating wire assembly is embedded in the insertion tube for communicating with external intelligent industrial control equipment and generating heat after receiving a signal.

[0021] The advantages of adopting the above technical solution are: the hooking strip is made of a shape memory alloy and can take on different shapes under different temperature ranges. In a first temperature range, the hooking strip is located outside the slot, effectively hooking the adhesions in the patient's body. In a second temperature range, the hooking strip bends toward the slot and engages with the slot within the second temperature range. When the micro-heating wire assembly is not in use, the hooking strip is in a stored state. When the hooking strip needs to be swung out of the slot, the micro-heating wire assembly generates heat to bring the temperature to the first temperature range, causing the hooking strip to bend toward the slot opening and pass through the slot. This flexible and controllable design allows medical staff to conveniently control the extension and retraction of the hooking strip according to the needs of the surgical process, ensuring the smooth progress of the surgical operation while preventing the hooking strip from interfering with or damaging surrounding tissue when not necessary. By utilizing the characteristics of the shape memory alloy and combining the communication connection between the micro-heating wire assembly and external intelligent industrial control equipment, the shape change of the hooking strip can be precisely controlled. Medical staff can send signals through intelligent industrial control equipment according to the specific surgical situation to accurately adjust the heat generation of the micro-heating wire assembly, so as to accurately change the shape of the connecting strip at the right time. This enables the foreign body forceps structure to better adapt to the individual differences of different patients and complex and changeable surgical scenarios, improving the accuracy and adaptability of surgical operations; the micro-heating wire assembly in the above technology is an existing technology, which includes a heating wire body, a temperature controller arranged on the operating forceps and a small battery or wire for providing power support to the heating wire body. Since the micro-heating wire assembly is an existing technology, its structure and function are No further elaboration is needed; in the above technology, the phase change temperature range of the shape memory alloy is limited by the different shape memory alloy materials. The phase change temperature range of the conventional shape memory alloy is above 35 degrees, that is, below 35 degrees is the second temperature range, and above 35 degrees is the first temperature range. Therefore, controlling the heat generation of the heating wire to change the temperature can achieve the morphological change of the memory alloy. Since shape memory alloy is an existing technology, its structure and function are not described in detail; in the above technology, cooling can be achieved by infusing flushing fluid or gas, etc. This cooling method is a medical means and can be adjusted according to actual needs.

[0022] The present invention further provides that: the insertion tube is provided with an imaging hole along its length direction, the imaging hole is connected to the end surface of the starting end of the insertion tube and an imaging hole is formed, the imaging component includes an image acquisition lens arranged at the imaging hole and an optical fiber for communicating with the image acquisition lens, the optical fiber is arranged in the imaging hole, the end of the optical fiber passes through the end of the insertion tube and forms a connection end for electrically connecting to an external imaging device.

[0023] The benefits of adopting the above technical solution are: in the above technology, the image acquisition lens is set at the imaging hole, which can directly obtain image information inside the patient's body. The optical fiber is connected to the image acquisition lens through communication, and the optical fiber is set in the imaging hole, so that the collected image signal can be stably transmitted to the external imaging device, which enables medical staff to clearly and accurately observe the position, shape and surrounding tissue of the patient's intrauterine contraceptive ring during the operation, including the distribution and degree of adhesion tissue, etc., providing a reliable visual basis for the surgical operation, which helps to improve the accuracy and success rate of the operation; the optical fiber in the above technology has good signal transmission performance, which can effectively reduce the loss and interference of the image signal during the transmission process. Setting the optical fiber in the imaging hole not only protects the optical fiber from damage by external factors, but also ensures its stable position in the insertion tube, thereby ensuring that the image signal can be stably and continuously transmitted to the external imaging device. This stable image transmission is crucial to the smooth progress of the operation, avoiding misjudgment and operational errors caused by unstable image signals; by obtaining clear in-vivo images in real time, medical staff can more accurately judge the scope and depth of the surgical operation, avoiding unnecessary damage to the uterine wall and other surrounding tissues during the ring removal process; the optical fiber in the above-mentioned technology is an existing technology, so its structure and function will not be described in detail. At the same time, the image acquisition lens is also a conventional technology, which can be replaced with an endoscopic lens according to actual use requirements or production requirements. Since it is an existing technology, its structure and function will not be described in detail.

[0024] The present invention further provides that: the radial cross-section of the insertion tube is square and the four corners of the insertion tube are connected with smooth arc surfaces to form chamfered surfaces.

[0025] The benefits of adopting the above technical solution are: in the above technology, the radial cross-section of the insertion tube is square and the four corners are connected by smooth arc surfaces to form chamfered surfaces. Compared with the traditional circular cross-section insertion tube, the square design increases the contact area between the insertion tube and the inner wall of the insertion channel, provides better grip and stability, and makes it easier for doctors to control the direction and depth of the insertion tube during operation, reduces shaking and deviation during the insertion process, and improves the accuracy of insertion, which is especially advantageous in narrow or tortuous physiological cavities; at the same time, the smooth arc chamfers of the four corners effectively eliminate sharp edges, and during the insertion process, greatly reduce the risk of scratching and tearing of surrounding tissues. Whether during insertion or withdrawal, it can gently pass through the tissue, avoid unnecessary trauma, reduce the incidence of complications such as bleeding and inflammation, and help patients recover quickly after surgery and improve the patient's medical experience.
