The library has general surgery textbooks but not Arora's specific instrument book. Since your query is broad ("General Surgical Principles & Instruments"), here is a comprehensive overview based on standard surgical textbooks (Sabiston, Schwartz, Mulholland & Greenfield):
General Surgical Principles & Instruments
1. General Principles of Surgery
Asepsis & Antisepsis
- Asepsis: Preventing contamination of the operative field by pathogenic microorganisms
- Antisepsis: Use of chemical agents to destroy or inhibit microorganisms on living tissue
- Surgeon must follow scrubbing, gowning, and gloving protocols before every operation
Pre-operative Principles
- Thorough patient assessment (history, examination, investigations)
- Informed consent
- Correction of fluid, electrolyte, and nutritional deficits
- Prophylactic antibiotics where indicated
- DVT prophylaxis (stockings, LMWH)
Intra-operative Principles
- Proper patient positioning
- Adequate exposure of the operative field
- Gentle tissue handling — avoid crush injury
- Meticulous haemostasis
- Ensure adequate blood supply to anastomoses
- No tension on suture lines
- Negative resection margins (in cancer surgery)
- Adequate lymphadenectomy (minimum 12 nodes in colon cancer)
Post-operative Principles
- Monitoring of vitals, urine output, drain output
- Pain management
- Early ambulation to prevent DVT
- Wound care and infection surveillance
2. Wound Healing
| Type | Description |
|---|---|
| Primary intention | Clean wound, edges approximated with sutures |
| Secondary intention | Wound left open, heals by granulation |
| Tertiary (delayed primary) | Wound left open initially, then closed after 4–5 days |
Phases of Wound Healing
- Haemostasis (0–few hours) — platelet plug, clotting cascade
- Inflammatory phase (1–4 days) — neutrophils, macrophages
- Proliferative phase (4–21 days) — fibroblasts, collagen, angiogenesis
- Remodelling phase (21 days – 2 years) — collagen reorganisation, scar maturation
3. Sutures
Classification by Absorbability
| Type | Examples | Use |
|---|---|---|
| Absorbable | Catgut, Vicryl (polyglactin), PDS (polydioxanone) | Internal tissues, bowel anastomosis |
| Non-absorbable | Silk, Prolene (polypropylene), Nylon | Skin, vascular anastomosis |
Classification by Structure
- Monofilament — Prolene, Nylon, PDS (less infection risk)
- Multifilament/Braided — Silk, Vicryl (easier to handle, more tissue drag)
Suture Size
- Larger number = finer suture (e.g. 4-0 is finer than 2-0)
4. Surgical Instruments — Classification
A. Cutting & Dissecting
| Instrument | Use |
|---|---|
| Scalpel (BP handle + blade) | Skin incision; Blade No. 22 (large incisions), No. 15 (curved/fine), No. 11 (stab incisions) |
| Scissors — Mayo | Cutting tough tissues, sutures |
| Scissors — Metzenbaum | Delicate dissection |
| Diathermy (electrocautery) | Cutting and coagulation |
B. Grasping & Holding
| Instrument | Use |
|---|---|
| Tissue forceps (toothed) — Rat-tooth | Holding skin edges |
| Non-toothed forceps — Debakey | Handling delicate tissues/vessels |
| Babcock's forceps | Holding bowel without crushing |
| Allis forceps | Holding fascia or edges of wound |
| Sponge-holding forceps (Rampley's) | Holding swabs for skin preparation |
C. Haemostatic (Artery Forceps/Clamps)
| Instrument | Use |
|---|---|
| Artery forceps (mosquito clamp) | Clamping small vessels |
| Kocher's forceps | Toothed, for heavy tissue |
| Spencer Wells forceps | Clamping larger vessels |
| Right-angle (Mixter) clamp | Passing ligatures around vessels |
D. Retractors
| Instrument | Type | Use |
|---|---|---|
| Langenbeck retractor | Hand-held | General retraction |
| Deaver retractor | Hand-held | Deep abdominal retraction |
| Balfour retractor | Self-retaining | Abdominal surgery |
| Finochietto retractor | Self-retaining | Thoracic surgery |
| Weitlaner retractor | Self-retaining | Superficial/orthopaedic |
E. Suturing Instruments
| Instrument | Use |
|---|---|
| Needle holder (Mayo-Hegar) | Holding curved suture needle |
| Gillies needle holder | Combined needle holder + scissors |
F. Drainage
- Corrugated drain — superficial wounds
- Redivac (closed suction) — post-mastectomy, neck dissection
- Robinson drain — general abdominal
- T-tube — common bile duct drainage after CBD exploration
- Intercostal tube drain — pneumothorax/haemothorax
5. Diathermy (Electrosurgery)
| Type | Mechanism | Use |
|---|---|---|
| Monopolar | Current flows patient → active electrode → return pad | Most common; cutting and coagulation |
| Bipolar | Current flows between two tips of forceps only | Near nerves/vessels; safer |
- Cutting mode: Continuous current → vaporises tissue
- Coagulation mode: Pulsed current → chars/desiccates tissue
- Blend mode: Mix of both
6. Sterilisation & Disinfection
| Method | Suitable For |
|---|---|
| Autoclaving (steam under pressure, 134°C) | Most metal instruments |
| Dry heat (160°C, 1 hour) | Glassware, powders, oils |
| Ethylene oxide gas | Heat-sensitive instruments (endoscopes) |
| Glutaraldehyde (Cidex) | Endoscopes, delicate instruments |
| Gamma radiation | Single-use disposable items |
This covers the core topics of General Surgical Principles & Instruments as per standard surgical curricula. Feel free to ask specific questions on any topic — for example: "What is the use of Babcock's forceps?" or "Explain types of wounds" — and I'll provide a detailed answer!
