Hemostats and Root Forceps: Design, Applications, and Clinical Significance in Modern Surgery and Dentistry

1. Introduction

Surgical instruments are at the heart of general and specialty medical and dental care. Hemostats and root forceps are two of the most valuable instruments in the two specialties. Despite shape differences, use, and application, both instruments are the intersection point in the practice of precision, effectiveness, and security in clinical practice. Their anatomic form, ergonomic shape, and functional versatility render them inevitability instruments in the armamentariums in surgery.

2. Hemostats: Evolution and Classification

Hemostats have continued to be a component of surgery since the beginning of operative medicine. Since the word is Greek, with “haima” (blood) and “stasis” (stop), hemostats are applied nearly exclusively for the very purpose of occluding vessels in an effort to minimize intraoperative blood loss.

Historical Perspective

•Prior models were referred to in Roman texts on surgery.

•Ambroise Paré (1510–1590), one of the earliest French surgeons, used primitive clamps in early ligature operations.

•19th century refined the design with Jules-Émile Péan and William Halsted who later refined the design.

Basic Classification of Hemostats

•By Size:

Small: Mosquito forceps

Medium: Kelly, Crile hemostats

Large: Rochester-Carmalt

•By Tip Design:

Straight tips

Curved tips

Right-angled tips

•By Serration:

Horizontal

Longitudinal

Cross-hatched

•By Function:

Hemostasis (vascular)

Tissue holding

Blunt dissection

3. Structure and Design of Hemostats

Modern hemostats are the culmination of gigantic metallurgical and ergonomic developments, finely tuned to function under stressful operational conditions without inducing tissue trauma.

Major Components

• Blades or Jaws:

Serrated to prevent vessels

Typically blunt-tipped to prevent puncture

• Locking Mechanism:

Ratchet lock mechanism

Facilitates graduated force of clamping

• Handles:

Typically circled by fingers

Weighted to provide leverage and control

Material Considerations

• Stainless Steel:

Grade 410 and 420 for high hardness

Corrosion resistance needed for repeated sterilization

• Titanium:

Light in weight and non-magnetic

Used in ophthalmic or neurosurgical hemostats

• Polymer Coated Tips:

Used in electrosurgery to avoid thermal conduction

4. Hemostats in Surgical Practice

Hemostats are essentials in and of themselves in almost all cases — from general surgery to subspecialties such as cardiovascular, orthopedic, and plastic surgery.

Typical Uses

• clamping small vessels before ligation

• control of bleeding in deep cavities

• temporary retention of sutures and operating thread

• Blunt dissection by opening and closing jaws in planes of dissection

Surgical Uses

• In appendectomy: Clamping of vessels of mesoappendix

• In thyroidectomy: Clamping of superior thyroid artery

• In trauma surgery: Temporary blood vessel occlusion

5. Hemostats in Dentistry

Less frequent than in general surgery, but with a special use in dental surgery where they are used most in complicated extractions and periodontal surgery.

Uses in Dentistry

• Clamping of bleeding mucosal vessel

• Retraction cord or gauze holding

• Suture placement or removal aid

• Removal of small oral foreign bodies aid

6. Root Forceps:

Root forceps are endodontic extractors used to remove and engage roots and root segments of teeth. They have an anatomical space-accessible design with adequate grip and control.

Functionality

• Endodontic failure by apical root extraction

• Root fragment removal without adjacent bone loss

•Can be utilized in alveolar surgery or replantation procedure on the schedule

7. Root Forceps Design and Construction

Design of root forceps is specialized but adaptable, conforming to the shape and form of different roots.

Chief Features

•Beaks:

tapering, narrow, pointed

Altered to seat upon contact area of root without crushing

• Hinged Joint:

Opposes hard closure movement with minimal user force

• Handles:

increasingly curved to offer greater access to posterior regions

Materials

• Usually forged in hardened surgical stainless steel

• Can be sandblasted or serrated on surface to improve grip

8. Region and Function of Root Forceps

Root forceps vary significantly based on their recommended location within the oral cavity.

By Location

• Maxillary Forceps:

→ №150 (universal)

→ №286 (Bayonet-shaped for root tips)

• Mandibular Forceps:

→ №151 (universal)

→ Cowhorn (№23) for molar roots

By Function

• Universal vs. regional

• Pediatric vs. adult

• Surgical vs. routine extraction forceps

9. Dental Extraction Role of Root Forceps

Root extractions of teeth require a balance between control and force to avoid alveolar trauma.

Clinical Indications

• Root tip fracture or remaining root tips in crown fracture case

• Brittle roots endodontically treated teeth, removal of

• Surgical extraction of third molars having diverging roots

Preferred Technique

• Elevator luxation prior to forceps application

• Sectioning of periodontal ligament by periotomes

• Rotatory or bucco-lingual rocking motion

10. Comparative Analysis: Hemostats vs. Root Forceps

Although both are grasp instruments, the shape and use setting are different.

Key Differences

• Hemostats:

Fine serrations, locking mechanism

Used to hemostasis and clamp

• Root Forceps:

Strong beaks to grip

To remove tooth roots

Common Features

• Stainless steel construction

• Need to be sterilized

• Ergonomic handles

11. Sterilization and Instrument Maintenance

Infection control is achieved by rigid sterilization practices on all reusable instruments.

Sterilization Methods

• Pressure steam (autoclaving)

• Dry heat sterilization

• Immersion chemical (glutaraldehyde or hydrogen peroxide)

•Heat-sensitive equipment plasma sterilization

Maintenance Best Practices

•Soaking in enzymatic cleaners before use

•Hand scrubbing of hinges and serrations

•Lubrication of jointed instruments

•Check for rust or visibility of cracks

12. Ergonomic and Material Considerations

Ergonomics have a vital part to play in minimizing the fatigue of users and maximizing clinical results.

Ergonomic Principles

•Optimal weight distribution

•Textured handles to avoid slipping

•Angulation to suit anatomy of hand

Material Characteristics

•Resistance to corrosion

•Non-glare surface to avoid glare

Although common in dental and surgical procedures, hemostats and root forceps are not weak. They result from material wear and tear, anatomical difference, and misuse.

Weaknesses Common to All

• Misuse of instruments with tissue damage as a result

• Metal fatigue causing snapping off thin tips or sticking at joints

• Being impossible for posterior roots to be reached by routine forceps

• Slipping due to faulty serration or roughened surface

Situational Weaknesses

• In calcified root canals or extreme root curvature

• Highly closed surgical fields

• Patients with limited oral aperture (trismus)

• Hemostasis failure in coagulopathic patients

Patient safety is basically linked with use, sterilization, and treatment of the instrument.

Safety precautions

• Daily inspection of instruments before use and sterilization

• Hemostatic locking mechanism testing

• Prevention of the application of too much force during root luxation

• Use of the correct fit of forceps to the tooth being removed or fragment to be removed

Reduction of Hazards

• Daily instrument training for staff

• Operating room tray checklists

• Detection and removal of broken practice instruments
