International Classification:
A47K 3/022
US Classification:
4445, 44203
Abstract:
A sitz bath helps patients suffering from hemorrhoids and other conditions to void their bowels. A flushing sitz bath utilizes an attached liquid filling tube, integrated water distribution channel and valve, a swing check valve, and a content-emptying flapper valve. This device helps to increase the efficiency of filling the sitz bath basin with the preferred liquid, as well as increasing the ease and cleanliness of the subsequent emptying of the basin contents by minimizing bodily strain and mess.
Elliptical Excision Clamp
US Patent:
2008017, Jul 17, 2008
Filed:
Jan 16, 2007
Appl. No.:
11/623412
Inventors:
Kwok Wai Chiu - Plano TX, US Timothy Chiu - Plano TX, US Kwok Hung Chung - Plano TX, US
International Classification:
A61B 17/28
US Classification:
606205
Abstract:
An elliptical excision clamp helps in the removal of superficial lesions and abnormalities as well as the subsequent suturing of said removal of lesions. An elliptical excision clamp utilizes a pair of half-elliptical shaped clamp jaws curved at an appropriate ratio for the target surgical area, a number of suture hole and slot pairs on the clamp jaws used to facilitate suturing, a crossed members array with finger loops, and a pivot point pin used to connect said crossed members. This device helps minimize bleeding and operation time, and maximizes surgical efficiency and wound management.
Apparatus For Punch Biopsy
US Patent:
2009001, Jan 15, 2009
Filed:
Sep 21, 2008
Appl. No.:
12/234696
Inventors:
KWOK WAI CHIU - Plano TX, US Timothy Chiu - Plano TX, US William S. Wang - Richardson TX, US
International Classification:
A61B 10/00
US Classification:
600562
Abstract:
A punch biopsy apparatus for removing all or a portion of a suspect dermal growth. A punch biopsy apparatus has: a hollow cylinder body; a coring blade at the base of the hollow cylinder body; at least one scooping blade pivotally secured by an axle and a pair of pivot seats within the cylinder body, where each scooping blade is semicircular, a longitudinally-moveable plunger secured within the hollow cylinder, where the plunger has at least one plunger leg for contacting each scooping blade, and each plunger leg transfers longitudinal plunger movement to its respective scooping blade, thereby causing rotational scooping-blade movement. This device helps minimize bleeding and minimize damage to the biopsy sample being retrieved.
