Medical instrument manufacturers make kelly clamps in various models to give surgeons flexibility in operations. The kelly clamp types are distinguished from each other mainly through the shape and curvature of their jaws. Common surgical instruments used with these forceps include needle holders, artery forceps, and hemostatic clamps.
Straight kelly clamp
Straight kelly clamps are among the most common required surgical instruments. The surgical clamps have gripping ridges on straight, non-curved jaw sections. This jaw shape is ideal for performing compression and grasping operations on arteries and tissue sections in straight access surgery. The straight kellys are also widely used in surgical dressing placement during wound care procedures.
Curb kelly clamp
The curb kelly clamp differs from the straight variants through a gentle curve along the length of its jaws. This curvature provides better access to cylindrical structures such as blood vessels deep inside the body cavities than straight jaws. The curbed kellys find frequent use in procedures requiring hemostasis, such as ligating blood vessels in surgical field exposure.
Short kelly clamp
Short kelly clamps, with jaws measuring 5 to 6 inches in length, are appropriate for smaller surgeries and wound dressing in restricted spaces. The limited lengths help deliver precise closure in procedures around delicate tissues or narrow blood vessels. Short kellys are equally suitable for routine maintenance of external wounds.
Long kelly clamp
The long kelly clamps, with jaws 8 to 10 inches in length, allow access to deeper body cavities while retaining significant grasping force. The extended reach eliminates the need for excess movement during major surgeries. The clamps also reduce the surgeon's hand and wrist fatigue through ergonomic designs.
Non-curved kelly clamp
Non-curved kelly clamps lack the curvatures seen on the kelly curvilinear clamps. This jaw profile, together with horizontal serrations along their entire length, offers a strong grasp suitable for clamping vessels regardless of orientation. Since their gripping surfaces do not differ whether they are used at the end or along their length, non-curved kelly clamps can rotate 360° to provide gripping flexibility from any position.
Medical supplies manufacturers construct kelly clamps from various metals and alloys. The selection of materials depends on the desired balance between strength, corrosion resistance, and patient safety. The commonly used materials are explained below.
Stainless steel
Stainless steel is by far the most common material used in manufacturing surgical instruments, including kelly clamps. The alloy's unique combination of strength, durability, and corrosion resistance is ideal for the regular stressful demands of an operating theatre. Kelly clamps see intense use as they are exposed to body fluids, sterilization, and continuous handling. Stainless steel, unlike most low-cost metals, does not rust or weaken over extended exposure to moist environments. Its rigidity allows it to maintain precise shapes necessary for grasping and clamping operations.
Carbon steel
Carbon steel is another widely used material for kelly clamps. The alloy's high tensile strength makes it suitable for heavy-duty surgical instruments required in cardiothoracic or orthopaedic operations. Although corrosion-resistant than stainless steel, carbon steel kelly clamps must be cleaned and sterilised properly after each usage. They are typically coated with biocompatible materials to avert rusting, particularly when exposure to dampness lasts for extended periods.
Titanium
Although titanium kelly clamps are less common, they are used in very selective procedures requiring joints or clamps with extra strength and minimal weight. The metal's exceptional resistance to corrosion renders it ideal for long-term implants and usages in patients with metallic allergies. Titanium's biocompatibility means it does not elicit adverse reactions in patients. However, its relatively high cost makes titanium clamps generally restricted to specialty surgeries.
Medical-grade alloys
Manufacturers of medical devices sometimes combine kelly clamp materials into custom alloys. These combinations aim to improve selected features such as increased strength, reduced density, and superior resistance to tarnishing or wear. For instance, adding nickel improves corrosion resistance, while molybdenum enhances the alloy's strength at elevated temperatures. Such specialised kelly clamps are suitable for specific surgeries or environmental conditions within the human body.
Plastics and composites
Although not as common, Kelly clamps are sometimes constructed from plastic or composite materials. The non-metal materials are often used in surgeries requiring electromedical devices, anatomical clamps, and minimal thermal conductance. Plastic compounds balance flexibility with sufficient durability for one-time use kelly clamps. Although less robust than metallic variants, kelly clamps made of plastics are economical and lighter in weight.
The kelly clamp is a crucial instrument in many surgeries, and businessmen need to understand the commercial value of these instruments and their role in various surgical procedures.
Hemostasis and vessel clamping
Kelly clamps are primarily valued for their hemostatic properties in many operations. They are mainly employed to clamp blood arteries, restricting blood flow and allowing surgeons to operate safely on vascular structures. This makes them very important in procedures like abdominal, cardiovascular, and orthopaedic surgery, where precise control of bleeding is crucial. Suppliers of kelly clamps face great demand for these devices due to their importance in essential surgical procedures and their potential role in improving patient outcomes through better control of blood loss.
Versatility in surgical procedures
Kelly clamps are multipurpose. Apart from hemostasis, these clamps are used in tissue grasping, organ manipulation, and securing suturing materials. The clamps assist during the excision and closure of tissues. The clamps find uses in general surgery, gynaecological surgery, and urological surgery. This wide utilisation increases suppliers' demand for quality kelly clamps in hospitals and surgical centres.
Bulk purchasing and cost considerations
Hospitals generally purchase kelly clamps in bulk, negotiating favourable pricing terms. The quantity purchases increase the clamps' unit economic cost, so suppliers providing discount incentives for large orders enjoy increased sales. Additionally, given their frequent use, kelly clamps are relatively inexpensive, making them a cost-effective choice for healthcare facilities. Suppliers therein provide quality, durable, easy-to-sterilize clamps. The clamps reduce operating costs through extended reuse and require less frequent replacement.
Sterilisation and infection control
As kelly clamps are used in invasive procedures, they must be readily sterilised between customer use. Their construction materials, such as stainless steel and carbon steel, resist sterilisation methods like autoclaving. Buyers should choose clamps that maintain integrity and resist corrosion after repeated sterilisation. This ensures effective infection control and patient safety. Suppliers provide clamps that withstand intensive sterilisation processes. The reduced risk of infection advances operational efficiency and patient turnover, further benefiting the healthcare facility.
When selecting kelly clamps, healthcare practitioners consider various factors that directly impact performance, durability, and patient safety. Below are the key factors influencing clamp selection.
Material and durability
When selecting clamps, surgeons consider their construction material. Manufacturer's material options include various grades of stainless steel, carbon steel, and titanium. Kelly clamps made of high-quality, corrosion-resistant stainless steel offer superior durability and withstand the rigours of sterilisation and prolonged use. In addition to hemostasis and tissue handling, kelly clamps serve a myriad of purposes during surgeries, including organ traction and tying sutures. Surgical centres prefer kelly clamps made of very strong steel alloys with sufficient clamp strength for heavy-duty applications.
Ergonomic design and sterility maintenance
As surgeons use kelly clamps repetitively for extended durations, they look for ergonomic designs that minimise hand fatigue. Finger grooves or ridges greatly help with grip, reducing slippage. Healthcare professionals also ensure the clamp's surface finish is smooth, reducing tissue trauma upon grasping. They consider how well the clamp maintains sterility, given the rising concern over infection control in healthcare. They choose clamps with easily cleaned surfaces, no crevices harbouring contaminants, and compatible with standard sterilisation techniques.
Ease of use and reputation
Surgeons value clamps that open, close, and lock smoothly with minimal effort. This is critical in fast-paced operations requiring quick, precise control of bleeding or tissue handling. To gauge performance, healthcare practitioners also review recommendations from peers and the reputation of the clamp manufacturers. They choose kelly clamps with documented clinical evidence supporting their effectiveness and research. To ensure consistent quality, they opt for trusted brands who manufacture their clamps through certified processes, invariably linked to improved patient outcomes.
A1: Kelly clamps are mainly used to secure blood vessels, which restricts blood flow during procedures.Coidal clamps are also used on other tissues to enable the surgeon to work safely without excessive bleeding.
A2: While many forceps have varying jaw shapes for distinct uses, kelly clamps have straight, parallel jaws with horizontal serrations running partly across their gripping surfaces. This unique profile offers a firm, stable grasping action for generalised clamping tasks.
A3: Dominant kelly clamps have serrations that run parallel across their jaws, offering a strong grasping surface. In contrast, the serrations of non-dominant kelly clamps form a cross pattern. This configuration on non-dominant clamps provides a better tissue grasp.
A4: Kelly clamps are almost always reusable. They are typically formed of stainless steel to provide for multiple sterilised uses. However, one-time use variants do exist, typically made from plastics during procedures necessitating quick clamp removal.
