Description

Technical Field

[0001] This invention belongs to the field of surgical instrument technology, and specifically discloses a suture forceps for nasal surgery. Background Technology

[0002] Intranasal surgeries, such as septoplasty, turbinate resection, and intranasal tumor resection, often require wound closure within the narrow and limited nasal passages, posing a significant challenge to surgeons. Currently, in clinical practice, conventional surgical forceps (such as needle holders and tissue forceps) are often used in conjunction with independent sutures to complete the suturing procedure.

[0003] However, the existing suturing technique has the following obvious drawbacks: Limited operating space and limited tool functionality: The nasal cavity has a small internal space, and traditional surgical forceps usually only have a single function of clamping or squeezing. During suturing, doctors need to frequently switch between various instruments such as needle holders, tissue forceps, and scissors, which not only makes the steps cumbersome and prolongs the operation time, but also makes it easy to interfere with the surgical field when changing instruments in a limited space, increasing the difficulty of operation and the risk of accidentally damaging surrounding normal tissues.

[0004] Suture management is difficult: before and after inserting the suture needle into the nasal cavity and performing suturing, the thin suture is very easy to get tangled or knotted in the instrument channel or nasal cavity, affecting suturing efficiency and may even lead to suturing failure or the need to repeat the operation.

[0005] Unclear surgical field and tissue fluid interference: During intranasal surgery, blood and tissue fluid seeping from the wound can easily accumulate around the wound, obscuring the surgical field of vision and making it difficult for doctors to clearly identify the wound edges, directly affecting the accuracy and quality of suturing.

[0006] Lack of integrated wound management solutions: Existing instruments often separate functions such as pressure hemostasis, suturing assistance, and suture cutting. There is a lack of an integrated instrument that can simultaneously apply pressure to the wound to facilitate suturing, assist in guiding the suture needle, manage the sutures, and, when necessary, aspirate secretions and maintain a clear surgical field.

[0007] To address the aforementioned issues, there is a need in the art for a multifunctional suture forceps specifically designed for intranasal surgery. This instrument should simplify the suturing process, effectively manage sutures, provide a clear surgical field, and improve the efficiency, precision, and safety of intranasal suturing procedures. Summary of the Invention

[0008] In view of this, the purpose of this invention is to provide a suture passer for nasal surgery to solve the problems mentioned in the background art, such as limited operating space, single tool function, difficulty in suture management, unclear surgical field and tissue fluid interference, and lack of integrated wound treatment solution.

[0009] To achieve the above objectives, the present invention provides a suture forceps for nasal surgery, comprising a forceps body structure, one end of which is connected to a first pinch head, and the other end of which is connected to a second pinch head. The first pinch head and the second pinch head are distributed opposite to each other and have the same shape. A silicone strip and a blade are provided on the opposite inner surfaces of the first pinch head and the second pinch head. A notch is provided on the first pinch head and the second pinch head between the silicone strip and the blade, and the silicone strip and the blade are distributed opposite to each other with the notch as the center. A thread-guiding ring is fixed to the outside of the first pinch head, and a suture thread runs through the thread-guiding ring. A curved needle is fixed to one end of the suture thread near the first pinch head. The notch is configured to form a guide channel for the curved needle to pass through to suture the wound when the first pinch head and the second pinch head are engaged, thus preventing the suture from tangling before suturing the wound.

[0010] In the above technical solution, the first pinch head and the second pinch head are both arc-shaped strip structures with raised upper ends. The silicone strip is elastic and is distributed on the upper part of the inner side of the first pinch head and the second pinch head. The surface of the silicone strip is rough and the blade is distributed on the inner side of the first pinch head and the second pinch head near the upper end.

[0011] In the above technical solution, the clamp body structure further includes a first handle and a second handle that rotates on the first handle. The lower ends of the first pinch head and the second pinch head are fixed with snap-fit ​​strips. The first pinch head is detached and fixed to the first handle through the snap-fit ​​strips, and the second pinch head is detached and fixed to the second handle through the snap-fit ​​strips. The rear ends of the first handle and the second handle are connected with grips.

[0012] In the above technical solution, the second pinch head is further connected to a suction pipe, the suction end of the suction pipe is distributed inside the notch on the second pinch head, the discharge end of the suction pipe passes through the second handle and the grip, the discharge end of the suction pipe is fixed with an outer pipe, and a hand-operated water pump is connected to the outer pipe.

[0013] In the above technical solution, the hand-operated water pump is further located below the handle, the hand-operated water pump abuts against the handle, and the outer pipe is fixed to the handle.

[0014] In the above technical solution, the second handle and the first handle are further provided with a connecting head at the end near the grip, and the connecting head is threaded at the end near the grip, and the connecting head is threadedly connected to the grip.

[0015] In the above technical solution, the second knife handle and the end of the first knife handle away from the grip are conical, the ends of the first pinch head and the second pinch head are provided with rounded corners, and the first pinch head and the second pinch head are elastic.

[0016] In the above technical solution, the silicone strip on the first pinch head and the silicone strip on the second pinch head abut each other, the silicone strip is elastic, and the silicone strip has a strip-shaped sheet structure.

[0017] In the above technical solution, the notch is a semi-circular hole structure, the edge of the notch is rounded, and the notch is distributed at the bottom edge of the first pinch head and the second pinch head.

[0018] Compared with the prior art, the present invention has the following beneficial effects: After the first and second pinch heads of the suture forceps pinch the wound in the patient's nasal cavity, the exposed part of the wound will be pinched closed. At this time, the medical staff can use another surgical forceps to drive the curved needle through the notch on the first and second pinch heads, so that the curved needle can drive the suture through the wound in the patient's nasal cavity and suture the wound in the patient's nasal cavity. This suturing technique is in line with the way medical staff suture wounds, and thus makes it easier for medical staff to quickly master the use of the suture forceps.

[0019] 2. After the curved needle in the suture clamp sutures the wound in the patient's nasal cavity, the medical staff's hand, through the handle, moves the rear ends of the first and second pinch heads to fit against the inner wall of the patient's nasal cavity. This tightens the suture through the suture loop and prevents it from fitting against the inner wall of the patient's nasal cavity. Then, the suture is cut using the blades on the first and second pinch heads, thereby increasing the portability of suturing the patient's nasal cavity wound.

[0020] 3. Based on the habits of medical staff in using surgical forceps, when the thumb and forefinger are inserted through the handle, the remaining fingers of the medical staff can hold the hand-operated water pump. When the remaining fingers of the medical staff squeeze the hand-operated water pump, the hand-operated water pump can draw tissue fluid from the patient's wound site through the external and internal connecting pipes, and then discharge the tissue fluid through the external pipes. This avoids the tissue fluid covering the sutured area of ​​the patient's surgical wound, improves the patient's wound suturing comfort, and ensures the normal progress of the wound suturing surgery.

[0023] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0025] Example 1: Please refer to Figures 1 to 8 As shown, the present invention provides a technical solution: This invention relates to a suture forceps for nasal surgery, comprising a forceps body structure, one end of which is connected to a first pinch head 2, and the other end of which is connected to a second pinch head 3. The first pinch head 2 and the second pinch head 3 are distributed opposite to each other and have the same shape. A silicone strip 31 and a blade 32 are provided on the opposite inner surfaces of the first pinch head 2 and the second pinch head 3. A notch 6 is provided on the first pinch head 2 and the second pinch head 3 between the silicone strip 31 and the blade 32. The silicone strip 31 and the blade 32 are distributed opposite to each other with the notch 6 as the center. A suture ring 21 is fixed to the outside of the first pinch head 2. A suture 1 passes through the suture ring 21. A curved needle is fixed to one end of the suture 1 near the first pinch head 2. The notch 6 is configured to form a guide channel for the curved needle to pass through to suture the wound when the first pinch head 2 and the second pinch head 3 are aligned, so as to avoid the suture 1 from getting knotted before suturing the wound.

[0026] The first pinch head 2 and the second pinch head 3 are both arc-shaped strip structures with raised upper ends. The silicone strip 31 is elastic and is distributed on the upper part of the inner side of the first pinch head 2 and the second pinch head 3. The surface of the silicone strip 31 is rough, and the blade 32 is distributed on the inner side of the first pinch head 2 and the second pinch head 3 near the upper end.

[0027] The clamp body structure includes a first handle 4 and a second handle 41 that rotates on the first handle 4. The lower ends of the first pinch head 2 and the second pinch head 3 are fixed with a snap-fit ​​strip 44. The first pinch head 2 is detached and fixed to the first handle 4 through the snap-fit ​​strip 44, and the second pinch head 3 is detached and fixed to the second handle 41 through the snap-fit ​​strip 44. The rear ends of the first handle 4 and the second handle 41 are connected with a handle 42. In actual use, medical staff first thread the end of the suture 1 through the suture loop 21, and then tie a curved needle to the end of the suture 1. Since the curved needle used in existing nasal surgery is semi-circular, when the suture 1 needs to suture the wound inside the patient's nasal cavity, the medical staff can tie the curved needle to the first pinch head 2, and then use the first pinch head 2 to drive the curved needle with the suture 1 to be delivered into the patient's nasal cavity. When the first pinch head 2 drives the curved needle to the inside of the patient's nasal cavity, the medical staff can use another surgical forceps to clamp the end of the curved needle. At this time, the curved needle required for wound suturing is separated from the suture forceps. When the medical staff needs to suture the wound inside the patient's nasal cavity, the medical staff's fingers pass through the handle 42 and use the handle 42 to drive the first knife handle 4 and the second knife handle 41 to open. At this time, the first pinch head 2 and the second pinch head 3 are separated. Then the medical staff use the handle 42 to drive the first knife handle 4 and the second knife handle 41 to merge. Then the first pinch head 2 and the second pinch head 3 are used to pinch the patient's wound, which makes it easier for the curved needle to drive the suture 1 to suture the wound in the patient's nasal cavity. When the first pinch head 2 and the second pinch head 3 pinch the wound in the patient's nasal cavity, the silicone strip 31 can increase the friction between the patient's nasal cavity tissue and the first pinch head 2 and the second pinch head 3, thereby facilitating the first pinch head 2 and the second pinch head 3 to pinch the wound in the patient's nasal cavity. However, when the first pinch head 2 and the second pinch head 3 pinch the patient's nasal cavity tissue, the patient's nasal cavity tissue will be blocked by the first pinch head 2 and the second pinch head 3, which makes it difficult for the curved needle to drive the suture 1 to suture the wound in the patient's nasal cavity. In order to solve this problem, notches 6 are provided on the first pinch head 2 and the second pinch head 3. When the first pinch head 2 and the second pinch head 3 pinch the wound in the patient's nasal cavity, the exposed part of the wound will be pinched closed. At this time, the medical staff can use another surgical forceps to drive the curved needle through the notch 6 on the first pinch head 2 and the second pinch head 3, so that the curved needle can drive the suture 1 through the wound in the patient's nasal cavity and suture the wound in the patient's nasal cavity. This suturing technique is in line with the way medical staff suture wounds, and makes it easier for medical staff to quickly master the use of the suture forceps. After the curved needle drives the suture 1 to suture the wound in the patient's nasal cavity, another surgical forceps clamps the curved needle that has penetrated the wound. Then, the medical staff's hands pull the first pinch head 2 and the second pinch head 3 through the handle 42, so that the first pinch head 2 and the second pinch head 3 can move inside the patient's nasal cavity. At the same time, the suture 1 passes through the suture ring 21, so that the rear end of the suture 1 is supported by the suture ring 21, avoiding friction between the part of the suture 1 that is about to penetrate the wound and the wound, thereby increasing the patient's comfort in suturing the wound. After the curved needle drives the suture 1 to suture the wound in the patient's nasal cavity, the medical staff's hand, through the handle 42, drives the rear ends of the first pinch head 2 and the second pinch head 3 to fit against the inner wall of the patient's nasal cavity. This tightens the suture 1 through the suture ring 21 and prevents the suture 1 from fitting against the inner wall of the patient's nasal cavity. Then, the suture 1 can be cut by using the blades 32 on the first pinch head 2 and the second pinch head 3. It should be noted that you should refer to the instruction manual appendix. Figure 3 The blade 32 is inclinedly positioned on the upper part of the raised ends of the first pinch head 2 and the second pinch head 3, while the blade 32 does not adhere to the bottom of the first pinch head 2 and the second pinch head 3. This can prevent the blade 32 from touching the patient's nasal tissue when the silicone strip 31 pinches the wound in the patient's nasal cavity, thus preventing the blade 32 from damaging the patient's nasal tissue.

[0028] Example 2: Please refer to Figures 1 to 8 As shown, based on Embodiment 1, the present invention provides a technical solution. Unlike Embodiment 1, in this embodiment, according to the habits of medical staff using surgical forceps, when the thumb and index finger of the medical staff pass through the handle 42, the remaining fingers of the medical staff can hold the hand-operated water pump 5. When the remaining fingers of the medical staff squeeze the hand-operated water pump 5, the hand-operated water pump 5 can draw tissue fluid from the patient's wound site through the external pipe 51 and the abutment pipe 52, and then discharge the tissue fluid through the external pipe, thereby avoiding the tissue fluid from covering the sutured area of ​​the patient's surgical wound, improving the patient's wound suturing comfort, and ensuring the normal progress of the wound suturing surgery.

[0029] The second squeezing head 3 is connected to a suction pipe 52. The suction end of the suction pipe 52 is located inside the notch 6 on the second squeezing head 3. The discharge end of the suction pipe 52 passes through the second handle 41 and the grip 42. The discharge end of the suction pipe 52 is fixed with an outer pipe 51. A hand-operated water pump 5 is connected to the outer pipe 51.

[0030] A hand-operated water pump 5 is located below the handle 42, and the hand-operated water pump 5 abuts against the handle 42. The outer pipe 51 is fixed to the handle 42.

[0031] To accommodate nasal cavities of different lengths, the first pinch head 2 is detached and fixed to the first handle 4 via a snap-fit ​​strip 44, and the second pinch head 3 is detached and fixed to the second handle 41 via a snap-fit ​​strip 44. At the same time, the second handle 41 and the first handle 4 have a connecting head 43 that rotates at the end near the handle 42. The end of the connecting head 43 near the handle 42 is threaded and threaded onto the handle 42. This makes it easy for medical personnel to replace the first handle 4 and the second handle 41.

[0032] The second handle 41 and the first handle 4 are conical at the ends opposite to the grip 42. The ends of the first pinch head 2 and the second pinch head 3 are rounded. The first pinch head 2 and the second pinch head 3 are elastic.

[0033] When a patient needs to undergo surgery, the first pinch head 2 and the second pinch head 3 come into contact with the patient's nasal cavity. To enhance the sterilization and portability of the suture forceps, both the first pinch head 2 and the second pinch head 3 are made of disposable silicone material. At the same time, the silicone strip 31 on the first pinch head 2 and the silicone strip 31 on the second pinch head 3 abut against each other. The silicone strip 31 is elastic, which can improve the comfort of the patient's surgical wound suturing. The silicone strip 31 has a strip-shaped sheet structure.

[0034] The notch 6 is a semi-circular hole structure with rounded corners at the edges. The notch 6 is distributed at the bottom edges of the first pinch head 2 and the second pinch head 3. When a patient's nasal surgical wound is sutured, tissue fluid may seep out from the wound site. This tissue fluid not only affects the suturing of the wound by medical staff, but also increases the patient's discomfort during the suturing process. To solve this problem, medical staff can connect the discharge end of the hand-operated water pump 5 to an external pipe. Based on the habits of medical staff in using surgical forceps, when the thumb and index finger of the medical staff are inserted through the handle 42, the other fingers of the medical staff can hold the hand-operated water pump 5. When the other fingers of the medical staff squeeze the hand-operated water pump 5, the hand-operated water pump 5 can draw tissue fluid from the patient's wound site through the external pipe 51 and the abutment pipe 52, and then discharge the tissue fluid through the external pipe, thereby avoiding the tissue fluid from covering the sutured area of ​​the patient's surgical wound, improving the patient's wound suturing comfort, and ensuring the normal progress of the wound suturing operation. When the hand-operated water pump 5 can aspirate tissue fluid from the patient's wound site through the external pipe 51 and the abutment pipe 52, the suction end of the abutment pipe 52 is located inside the notch 6. This allows the abutment pipe 52 to accurately aspirate the tissue fluid flowing out of the patient's wound suturing, preventing the tissue fluid from flowing randomly and thus ensuring the normal progress of the wound suturing surgery.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
