Description

Technical Field

[0001] This utility model relates to medical equipment, and more specifically to a forceps with convertible teeth for use in the operating room. Background Technology

[0002] During surgery, toothed forceps and toothless forceps are often used alternately depending on the specific needs of the procedure. This rotation is very common because their respective characteristics and uses complement each other well, helping surgeons to perform surgical procedures more precisely and safely.

[0003] In the early stages of surgery, when separating looser tissues, toothless forceps are typically used. Their smooth tips allow for gentle tissue separation, avoiding unnecessary damage. However, as the surgery progresses to deeper layers, requiring the separation and fixation of tougher tissues, the surgeon may switch to toothed forceps. The serrated edges of toothed forceps better grip harder tissues, preventing slippage and facilitating deeper dissection. During vascular manipulation, toothless forceps are generally used to separate tissues surrounding blood vessels to avoid damaging the fragile vessel walls. However, when fixing blood vessels for ligation or suturing, toothed forceps may be used to ensure the vessels do not slip during the procedure, improving surgical safety and accuracy. In organ manipulation, toothless forceps are usually used for gentle manipulation of the organ surface to avoid damage. However, when more complex operations require fixing or traction of the organ, toothed forceps may be used to ensure tissue stability. During the suturing stage, toothed forceps are generally used to fix the tissue before suturing to ensure that the tissue does not shift. After suturing, if gentle adjustments or inspections of the suture site are needed, toothless forceps may be used to avoid unnecessary pressure and damage to the suture site. In delicate procedures involving nerves, blood vessels, or other delicate tissues, toothless forceps are typically used to avoid damage to fragile tissues. When it is necessary to fix or pull these delicate tissues, toothed forceps may be used briefly, but extra care must be taken to avoid excessive clamping. Furthermore, in emergency situations during surgery, if tissue slips while using toothless forceps, the surgeon may quickly switch to toothed forceps to refix the tissue; if a risk of tissue damage is detected while using toothed forceps, the surgeon will switch back to toothless forceps to reduce further damage to the tissue.

[0004] In summary, the rotation of toothed and toothless forceps during surgery is both common and necessary. This rotation can be flexibly adjusted according to different stages of the surgery and specific needs, ensuring both high efficiency and minimizing tissue damage. Surgeons and nurses typically assess the progress of the surgery and the characteristics of the tissue to quickly determine and select the appropriate forceps to ensure the safety and success of the procedure.

[0005] In preoperative preparation in the operating room, the configuration of instruments is one of the key aspects to ensure the smooth progress of surgery. However, because the use of toothed and toothless forceps is often frequently alternating during surgery, multiple toothed and toothless forceps are usually prepared preoperatively to meet the operational needs at different stages of the surgery. While this preparation method meets the needs of the surgery, it also brings certain inconveniences. On the one hand, preparing multiple toothed and toothless forceps preoperatively undoubtedly increases the workload of preoperative preparation. The scrub nurse needs to strictly disinfect, inspect, and classify each forceps to ensure that each forceps is in a usable condition and can be quickly and accurately provided to the surgeon. This process not only consumes a lot of time and energy but also increases the complexity of instrument management, making it easy for problems such as instrument omission, confusion, or incomplete disinfection to occur, thereby affecting the safety and efficiency of the surgery. On the other hand, the frequent switching between the two types of forceps during the operation also increases the cumbersomeness of using surgical instruments. The surgeon needs to quickly switch forceps at different operational steps, which not only distracts the surgeon but may also cause temporary interruptions to the surgical procedure, thus prolonging the operation time. In addition, frequent changes of forceps can increase the risk of infection during instrument transfer, especially in surgical environments where aseptic operation is required, where even the slightest mistake can lead to serious consequences.
