Hospital equipment names and pictures
A surgeon needs surgical instruments for surgery, nowadays the human organ can be replaced by artificial ones. without any surgical instrument, the surgeon cannot be done surgery. so we will discuss Hospital equipment names and pictures
surgical instruments having different sizes and shapes. depends on the surgery surgeon uses the instruments, a surgical instrument is one of the important helping tools for the surgeon. with the help of instruments surgeons successfully done human body surgery.
hospital instruments that are used by surgeons are classified into 3 categories, that we will understand.
- Diagnostic instruments- A)Diagnostic instruments B)CT Scan C)Biopsies
- therapeutic instruments
- operative instruments
1) DIAGNOSTIC INSTRUMENTS
The instruments used for diagnostic purposes are;
A. Optical instruments:-
a) Laryngoscope and pharyngoscope;- it is used for direct examination of the larynx and specially used by anaesthetist for intubation.
b) Bronchoscope;- it is specially used for direct visualisation of the trachea and bronchial tree. it is commonly used for diagnostic as well as therapeutic purposes.
c) Mediastinoscope;- it is mainly used for examination and biopsy of superior mediastinal lymph nodes which is frequently involved in bronchial carcinoma.
d) Gastrointestinal endoscopy;–
Oesophagoscope: it is used for examination of the oesophagus. it is a hollow tube about 45cm long and 16-20mm in diameter.
e) Choledochoscope;- Choledochoscope is the technique of visualisation of the common and hepatic bile ducts through choledochotomy. the rigid choledochoscope is an L- shaped instrument with lighting, viewing and irrigating systems.
f) Laproscope;- it is mainly used by gynaecologist for examination of the pelvis and therapeutic purpose such as tubal ligation.
g) Arthroscope;- it is an endoscopic examination of joints.
h) Urological endoscopy;- it is a recent addition in urology. it is useful in a large number of patients to visualise the renal pelvis.
B) CT Scan
-Computerised axial tomography provides information about tissue density in a thin section of tissue.
-This technique was developed in 1972 by N. Hounsfield.
-The idea was based on the assumption that the measurement of x-rays passing through the body could provide information on all tissue in the path of an x-ray beam. when the beam is multidirectional and data obtained is computed and presented in such a form to produce a three-dimensional picture.
Examination of living tissue removed from the body.
a)Curette;- The curette is a scoop-like instrument used to scrape off the material of tissue for biopsy.
b)Needle Biopsy;- Due to simplicity and speed, it is the most frequent technique in the biopsy.
Advantage;- it can be performed under local anaesthesia with minimum facilities and minimum trauma.
c)Biopsy punch forceps;-
Use: remove a piece of tissue by occlusion of two cupped jaws. these are suitable for mucosal biopsies.
these are some Hospital equipment names and pictures.
