A palatal obturator is a prosthesis that totally occludes an opening such as an oronasal fistula (in the roof of the mouth). They are similar to dental retainers , but without the front wire. Palatal obturators are typically short-term prosthetics used to close defects of the hard/soft palate that may affect speech production or cause nasal ...
Disposable trocars Laparoscopic instruments for insertion through trocars. A trocar (or trochar) is a medical or veterinary device used in minimally invasive surgery.Trocars are typically made up of an awl (which may be metal or plastic with a pointed or tapered tip), a cannula (essentially a rigid hollow tube) and often a seal.
The external obturator muscle or obturator externus muscle (/ ˌ ɒ b tj ʊəˈr eɪ t ər ɪ k ˈ s t ɜːr n ə s /; OE) is a flat, triangular muscle, which covers the outer surface of the anterior wall of the pelvis. It is sometimes considered part of the medial compartment of thigh, [1] and sometimes considered part of the gluteal region. [2]
Here it enters the thigh, through the obturator canal, and divides into an anterior and a posterior branch, which are separated at first by some of the fibers of the obturator externus, and lower down by the adductor brevis. [2] An accessory obturator nerve may be present in approximately 8% to 29% of the general population. [3]
Obturation is the necessary barrel blockage or fit in a firearm or airgun created by a deformed soft projectile. [1] A bullet or pellet made of soft material and often with a concave base will flare under the heat and pressure of firing, filling the bore and engaging the barrel's rifling.
The obturator process is an anatomical feature on the pelvis of archosaurs. It is a raised area of the ischium bone of the pelvis. [1] It is the origin of muscles that attach to the femur and aid in running. These muscles are called M. pubo-ischio-femoralis externus 1 and 2 in crocodylians.
A palatal lift prosthesis is a prosthesis that addresses a condition referred to as palatopharyngeal incompetence.Palatopharyngeal incompetence broadly refers to a muscular inability to sufficiently close the port between the nasopharynx and oropharynx during speech and/or swallowing.
The obturator foramen is the large, [citation needed] bilaterally paired opening of the bony pelvis. It is formed by the pubis and ischium . It is mostly closed by the obturator membrane except for a small opening, the obturator canal , through which the obturator nerve and vessels pass.
