Description

Technical Field

[0001] The utility model relates to the medical field, in particular to a pair of clamping round forceps made of a compound of ear cartilage and perichondrium. Background Art

[0002] Endoscopic tympanoplasty is currently the most commonly used method for treating conductive hearing loss in otology. In recent years, with the promotion of continuous perfusion mode, endoscopic tympanoplasty has been vigorously promoted, and many grassroots hospitals have gradually carried out this operation. After years of surgical summary by experts, autologous auricular cartilage or tragus cartilage and composites are commonly used and more recommended materials for tympanic membrane repair and ossicular chain reconstruction.

[0003] In order to make the tympanic membrane transplantation plant grow better, the cartilage taken from the tragus, concha cavity or the back of the auricle needs to be trimmed into the shape and size of the tympanic membrane. Currently, surgeons either use toothed forceps to clamp the cartilage, which can easily cause the cartilage to rupture, or place it on the instrument box and hold it down with their fingers to trim it, and use a surgical blade to trim the cartilage. This method can easily cause damage to the surgeon's fingers, make it difficult to fix the transplant, and easily cause it to fall and become contaminated, making the operation slower, taking too much preparation time, and making the operation more difficult.

[0004] After searching and investigating, no relevant patent application was found, and no suitable tweezers were used in otolaryngology. Therefore, the inventors provide a clamping round tweezers made of a complex of ear cartilage and perichondrium to solve the problems raised in the above background technology. Summary of the invention

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a pair of clamping round forceps made of a complex of ear cartilage and perichondrium, which can meet the needs of ear surgery for better clamping of the cartilage and perichondrium complex, ensure the safety and stability of the surgery, reduce the difficulty of ear transplant production, promote the development of ear endoscopic minimally invasive surgery, save operation time and improve operation efficiency.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A clamping round forceps made of a composite of ear cartilage and perichondrium, comprising an A rod and a B rod, wherein the inner side of the top end of the A rod is flatly welded to the inner side of the top end of the B rod, a rotating module is connected to one side of the center of the lower end face of the B rod, a bottom plate is connected to one side of the center of the lower end face of the A rod, and a plurality of concentric circles are engraved on the center of the upper end face of the bottom plate;

[0008] The rotating module and the B rod form an obtuse angle of 130-140 degrees, and the bottom plate and the A rod also form an obtuse angle of 130-140 degrees. When the A rod and the B rod are closed, the rotating module is arranged parallel to the upper side of the bottom plate;

[0009] Through the above technical scheme, through the round handle, connecting plate, rotating connecting shaft and groove, it is allowed that the operator can easily adjust the angle of the clamping round forceps to adapt to different operation requirements, and can also ensure the accuracy and stability during the operation, thereby greatly improving the flexibility and accuracy of the operation. The design of the groove adopts a fan-shaped structure, which is particularly suitable for the needs of carving cartilage and perichondrium complex. The fan-shaped groove provides a simple method for fixing and supporting the position of the hammer handle, while ensuring the correct positioning and stability of the perichondrium, simplifying the operating steps during surgery or production, and improving efficiency and safety. The fixed connection design between the A rod and the B rod ensures stability and consistency during use, thereby improving the accuracy of the operation. At the same time, stainless steel is selected as the material, not only because of its excellent mechanical properties and corrosion resistance, but also because of the durability and long-term stability of stainless steel, which ensures the long-term use of the clamping round forceps and reduces the surgical risks caused by aging or damage of the tools.

[0010] Further, the rotating module includes a round handle, a connecting plate and a rotating connecting shaft, the connecting plate is integrally connected with the bottom end of the B rod, the rotating connecting shaft is arranged on the connecting plate, and the bottom end of the rotating connecting shaft passes through the center of the connecting plate, the round handle is arranged at the bottom end of the connecting plate, and the bottom end of the rotating connecting shaft also passes through the center of the round handle, the round handle is rotatably connected with the connecting plate through the rotating connecting shaft, and a groove is provided on one side of the round handle;

[0011] Through the above technical solution, when the operator needs to adjust the angle of the clamping round tweezers, a rotational force is applied to the round handle by rotating the connecting shaft. The design of the rotating connecting shaft enables the round handle to be rotated smoothly and moderately, thereby ensuring the accuracy of the operation.

[0012] Furthermore, the groove is fan-shaped, and the angle of the groove is 45 degrees;

[0013] Through the above technical solution, it is convenient to ensure that only the perichondrium is needed at the position of the handle of the hammer when carving the cartilage and perichondrium complex. The 45-degree angle setting not only provides a sufficient rotation range to adapt to different operation requirements, but also avoids operational errors that may be caused by excessive rotation.

[0014] Furthermore, the rotary connection shaft and the round handle are rotationally connected via a thread;

[0015] Through the above technical solution, the rotating connecting shaft drives the round handle in a smooth and continuous manner to achieve precise control.

[0016] Furthermore, the A rod and the B rod are made of stainless steel, and the outer side walls of the A rod and the B rod are provided with a plurality of cylindrical protrusions on the upper side;

[0017] Through the above technical solution, the stainless steel material has good mechanical properties and corrosion resistance, ensuring the durability and long-term stability of the clamping round tweezers, so that its rotating connecting shaft drives the round handle in a smooth and continuous manner to achieve precise control.

[0018] Furthermore, the A rod and the B rod are arranged in a semi-cylindrical shape, and when the two are fitted together, they form a cylindrical shape;

[0019] Through the above technical solution, it is ensured that the doctor can hold it in his hand like a pen and can adjust the direction and rotate 360 ​​degrees.

[0020] Furthermore, the upper end surface of the round handle is provided with oblique lines;

[0021] Through the above technical solution, the operator can control the round tweezers more stably and reduce the risk of slipping or misoperation.

[0022] Furthermore, the concentric circles are solid lines or dotted lines; the diameters of the concentric circles are set from small to large to 5mm, 7mm, 9mm, 11mm, 13mm and 15mm;

[0023] The above technical solution allows us to measure the size of our grafts accurately when making cartilage and perichondrium complexes, facilitate better repairs, and avoid delays in surgery due to repeated adjustments.

[0024] Furthermore, the A rod and the B rod are configured to be flat.

[0025] Through the above technical solution, rod A and rod B are designed to be flat and form a flat shape when fitted together. When used with round clamping forceps, rod A and rod B can clamp the cartilage and perichondrium complex and provide stable supporting force. This design can ensure that the cartilage and perichondrium will not be damaged during the clamping process.

[0026] Furthermore, the total length of the clamping round tweezers is 125mm-130mm; the clamping round tweezers are smooth and free of burrs.

[0027] Working principle: When the ear cartilage and perichondrium complex needs to be clamped, the doctor applies a rotational force to the round handle 301 by holding the A rod 1 and the B rod 2, and rotating the connecting shaft 303, so that it is convenient to adjust the position and angle of the groove 304 of the round handle 301. The A rod 1 and the B rod 2 are set to be semi-cylindrical, and the two are fitted to form a cylindrical shape, which ensures that the doctor holds it in his hand like a pen, and can adjust the direction and rotation 360 degrees.

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] Example 1: Reference Figure 1-4 The utility model provides an embodiment: a clamping round forceps made of a cartilage and perichondrium complex, including an A rod 1 and a B rod 2, the inner side of the top of the A rod 1 is flatly welded with the inner side of the top of the B rod 2, a rotating module 3 is connected to one side of the center of the lower end face of the B rod 2, a bottom plate 5 is connected to one side of the center of the lower end face of the A rod 1, and a plurality of concentric circles 4 are engraved at the center of the upper end face of the bottom plate 5. The concentric circles 4 are designed on the bottom plate 5, which is convenient for the operator to measure the size of the graft when making the cartilage and perichondrium complex, so as to achieve accuracy, facilitate better repair, and avoid delaying the operation time by debugging back and forth. Because it provides a fixed point to prevent the clamped object from moving during the operation.

[0040] The rotating module 3 and the B rod 2 form an obtuse angle of 130-140 degrees, and the bottom plate 5 and the A rod 1 also form an obtuse angle of 130-140 degrees. When the A rod 1 and the B rod 2 are closed, the rotating module 3 is arranged parallel to the upper side of the bottom plate 5, and the rotating module 3 can rotate 360 ​​degrees through the rotation, which fully ensures that the ear cartilage and perichondrium are clamped stably and not easy to fall off.

[0041] The rotating module 3 includes a round handle 301, a connecting plate 302 and a rotating connecting shaft 303. The connecting plate 302 is integrally connected with the bottom end of the B rod 2. The rotating connecting shaft 303 is arranged on the connecting plate 302, and the bottom end of the rotating connecting shaft 303 passes through the center of the connecting plate 302. The round handle 301 is arranged at the bottom end of the connecting plate 302, and the bottom end of the rotating connecting shaft 303 also passes through the center of the round handle 301. The round handle 301 is rotatably connected to the connecting plate 302 through the rotating connecting shaft 303. A groove 304 is provided on one side of the round handle 301. When the operator needs to adjust the angle of the clamping round forceps, the rotating connecting shaft 303 applies a rotating force to the round handle 301. The design of the rotating connecting shaft 303 enables it to smoothly and 360 degrees rotate the round handle 301, in order to ensure the habit of each physician so as to make a cartilage incision of the cartilage complex.

[0042] The groove 304 is fan-shaped, and the angle of the groove 304 is 45 degrees, which is convenient for carving the cartilage and perichondrium complex to ensure that only the perichondrium is needed at the position of the hammer handle; the rotating connecting shaft 303 and the round handle 301 are connected by a threaded rotation, so that the rotating connecting shaft 303 drives the round handle 301 in a smooth and continuous manner to achieve precise control; the A rod 1 and the B rod 2 are made of stainless steel, and a number of circular protrusions are arranged on the outer side walls of the A rod 1 and the B rod 2. The stainless steel material has good mechanical properties and corrosion resistance, which ensures the durability and long-term stability of the clamping round forceps; A Rod 1 and rod B 2 are respectively configured to be semi-cylindrical, and when the two are fitted together, they form a cylindrical shape, which ensures that they can be held in the doctor's hand like a pen, and can be rotated 360 degrees and adjusted in direction; the lower end surface of the round handle 301 has an oblique pattern to ensure that the clamped repair membrane does not slip; the concentric circles 4 are small concave dots and discontinuous concentric circles, and the diameters are set to 5mm, 7mm, 9mm, 11mm, 13mm and 15mm, which is convenient for measuring the size of the graft when making the cartilage and perichondrium complex, so as to achieve accuracy, facilitate better repair, and avoid delaying the operation time due to back and forth debugging.

[0043] The total length of the clamping round tweezers is 125mm-130mm; the clamping round tweezers are smooth and free of burrs.

[0044] Example 2: Reference Figure 5 The utility model provides an embodiment: the A rod 1 and the B rod 2 are both set to be flat, and the A rod 1 and the B rod 2 are both designed to be flat, and form a flat shape when fitted, and the rest of the structure is the same as the first embodiment. When the round forceps are used, the A rod 1 and the B rod 2 can clamp the cartilage and perichondrium complex and provide a stable supporting force. This design can ensure that the cartilage and perichondrium will not be damaged during the clamping process.

[0045] When in use, the surgeon holds the clamping round forceps in the left hand like a pen, and places the removed ear cartilage and perichondrium complex between the rotating module 3 and the bottom plate 5. Because the bottom plate 5 has multiple anti-skid concentric circles with scales, and the rotating module 3 has cross anti-skid lines, the graft is firmly pressed and fixed between the rotating module 3 and the bottom plate 5 when the A rod 1 and the B rod 2 are closed; it is not easy to move;

[0046] The tightening and loosening of the rotating module 3 and the bottom plate 5 is determined by the opening and closing of the A rod 1 and the B rod 2 of the clamping round tweezers, and the opening of the A rod 1 and the B rod 2 is like the tightness of holding a pen, which is easy to control and easy to operate;

[0047] The cartilage and perichondrium are placed on the bottom plate 5 in the clamping round forceps, just like being placed on a cutting board for cutting meat; the pressing and fixing of the transplant by the rotating module 3 is like another hand firmly pressing the vegetables on the cutting board to stabilize it.

[0048] All the above actions are completed with the left hand, while the right hand holds a P-shaped mucosal knife (or 45-degree) mucosal knife, or a small surgical round knife.

[0049] If the removed graft contains bilateral perichondrium, press the graft and first separate a layer of perichondrium on the cartilage and the composite for later use.

[0050] If the cartilage and perichondrium are removed on one side, use the P-shaped mucosal knife (or 45-degree mucosal knife) in the right hand to trim the graft to create a cartilage island, leaving the perichondrium around as a skirt. On one side of the graft cartilage island, use the fan-shaped incision groove 304 of the clamping round forceps to rotate the module 3 to remove part of the cartilage to form a cartilage island with a certain depression, laying the foundation for full fit with the handle of the malleus during repair.

[0051] If the patient's cartilage is too thick and the patient is worried that the tympanic membrane cartilage is too thick and the mobility is poor, which will affect hearing, the round forceps can be used to place the graft horizontally in the middle, and then the round surgical blade can be used to evenly cut the graft into two parts from the central area. The thickness of the two parts can be controlled by the surgeon to ensure that the cut pieces are what the surgeon thinks is appropriate and what he wants. (This process is like a senior chef slicing fish slices without the fish slices flying around or hurting the surgeon.)

[0052] During surgery, if it is impossible to assess whether the size of the graft is appropriate, it is usually not found until a period of time after implantation that it is too large or too small, and the graft must be taken out, remade, and then re-inserted into the tympanic cavity to readjust its position, which delays the surgery. With this clamping round forceps, the bottom plate 5 has multiple concentric circles, like the annual rings of a tree, which can measure the size of the graft, avoiding the surgeon adjusting the size of the graft back and forth, and effectively saving surgery time.

[0053] The utility model realizes the need for better clamping of cartilage and perichondrium complex in ear surgery, ensures the safety and stability of the surgery, is conducive to reducing the difficulty of making ear transplants, is conducive to promoting the development of ear endoscopic minimally invasive surgery in ear surgery, saves operation time and improves operation efficiency.

[0054] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
