Oral temporary total hemostatic clamps

This invention is directed to hemostasis in the lips and the mucosal side of the cheek. These devices are not used for stopping each vessel from bleeding but are used for temporarily stopping the total blood supply to the entire surgical area. Model A has a pair of lip-shaped jaws for providing hemostasis in the entire upper or lower lip. The jaws are curved to conform to the entire lip and formed to interlock to permit longitudinal movement in jaw menbers. This structure is used for changing the size of jaws to adapt to different sizes of lips. Model A has two pairs of arms for maintaining a constant hemostatic pressure throughout the entire lip. Another design is constructed to provide hemostasis in a small area on the lip. Its jaws are semicircular and curved 90.degree. with semicircular parts of arms so that the surgeon can have access to surgical field easily without obstruction. Another model is designed to obtain hemostasis in the mucosal side of the cheek. Its circular jaws are combined with a pair of 90.degree. angulated arms. In the second and third models, the jaw-arm 90.degree. angulation is combined with an interlocked longitudinally movable system for keeping a constant parallel between the jaws in order to obtain hemostasis most effectively. A locking bolt-like bar has two threads. The distal thread is used for keeping the nut on the bar when releasing the device. The proximal thread is used for desirably adjusting the hemostatic pressure.

BACKGROUND OF THE INVENTION 
(1) Field of Invention 
This invention relates to surgical instruments for oral surgery. The 
procedure is based on temporarily stopping the total blood supply to the 
entire surgical area in the lip and the mucosal side of the cheek. These 
devices are not used for stopping each individual vessel from bleeding but 
are used for stopping the total blood supply to the entire surgical area. 
(2) Description of the Prior Art 
Instruments of the general type are known in the art and are exemplified by 
the following patents and publication: 
In the patent to Hoddick et Al U.S. Pat. No. 1,727,879 and Richter U.S. 
Pat. No. 1,437,995 both showed oral instruments conforming to mouth 
morphology but in actuality conforming to the maxillary bone for 
facilitating deep oral surgery. The primary advantage of my device has 
jaws which conform to the whole upper or lower lip whose purpose is to 
provide hemostatic pressure to the entire lip. 
In the patent to Olenik U.S. Pat. No. 1,913,770 noted ring jaws used for 
holding an absorbent pad and sponge for stanching the flow of blood from a 
wound left by the removal of one tonsil in such manner as to prevent no 
interference to an immediately succeeding operation on the opposite 
tonsil. My instrument provides hemostasis to the entire surgical area 
prior to and during surgery not after incision and/or excision of oral 
tissue. 
An inter-ringed clamp of Wolfson in the Annals of Surgery, 1933, pp. 
794-796, is a clamp which has unequal rings; and used to hold and secure 
tissues and viscera in abdominal operation or vaginal operation; but is 
not used for hemostatic purposes. 
In the patent to Bates U.S. Pat. No. 480,165 had a circular ring of jaw 
members which are of the same morphology as in my Model C; but is used on 
the skin for taking up the skin immediately around a snake-bite or other 
affection and cutting off the blood flow to and from the wound or 
affection whereby the poison or disease will be prevented from 
disseminating through the vascular system of the patient. Moreover, Bate's 
device has different types of arms compared with mine. 
In the patent to Rubin U.S. Pat. No. 2,250,605 also had circular ring 
members but they are of unequal size and used as a tissue holder and not 
for hemostatic purposes. Rubin's device has different types of arms 
compared with mine. 
In the patent to Black U.S. Pat. No. 2,100,730 has sliding hugging jaws for 
adjustability but has a different structure compared with my device. 
Moreover, Black's clamp is used for holding animals firmly and securely 
during the time that the animals are being operated upon or treated for 
any purposes. 
SUMMARY OF THE INVENTION 
Surgery of the lips and the mucosal sides of the cheek causes profuse 
bleeding. One objective of my invention is to prevent profuse bleeding of 
the entire surgical area by temporarily stopping the blood flow in the 
entire surgical field. These devices are not used for stopping each blood 
vessel from bleeding but are used for temporarily stopping the total blood 
supply to the entire surgical field. In order to stop the total blood flow 
in surgical field, the jaws of my invention are confined to the entire 
surgical area; one jaw being in the mouth and the other jaw is outside of 
the mouth. 
These devices have the locking bar system which has a bolt-like bar with 
spiral groove-like segments so that we can release these devices gradually 
in order to easily find out which vessels are still bleeding and then use 
regular hemostatic clamps to easily stop each vessel from bleeding. 
Another advantage of my devices (in Model B and C) is to combine the 
sliding hugging system in arms with the 90.degree. jaw-arm angulation so 
that two opposed jaws are always parallel in order to stop bleeding most 
effectively. 
The other objective of my invention is to provide a sufficient clear 
surgical field by having little or no bleeding during the procedure so 
that surgeons can operate easily, rapidly and precisely. 
Another advantage of my invention (in Model A) is to have two pairs of jaws 
for maintaining constant hemostatic pressure throughout the entire 
surgical lip. 
Another advantage of my invention (in Model A) is to have the sliding 
hugging system in jaws for changing the size of the jaw members in order 
to adapt to different sizes of entire upper or lower lips. My sliding 
hugging system is simpler than that of Black's device in that the jaws are 
thinner and thus easily inserted in the mouth.

DESCRIPTION OF THE PREFERRED EMBODIMENT 
Model A, shown in FIG. 1, comprises a pair of opposed jaws which are curved 
to conform to the entire upper or lower lip, shown in FIG. 10, so that we 
can perform a plastic surgery so that during plastic surgery, it is 
possible to adjust the size and/or shape of the entire upper and/or lower 
lip and we can perform other type of surgery on the entire upper or lower 
lip. Each jaw includes 2 parts 1,2, shown in FIGS. 2,3,4, which are 
connected by the sliding hugging system. The sliding hugging system 
comprises the curved channel in the left part of each jaw and a curved 
rod-like segment on the right part of each jaw as shown in FIG. 1. An 
enlarged sectional view of this sliding hugging system is shown in FIG. 5. 
The sliding hugging system is used for changing the size of jaws in order 
to adapt to different size of the entire upper or lower lip. Model A has 
two pairs of arms. Each pair has a locking bar system as shown in FIG. 6. 
This system comprises bolt-like bar 9 that can pivot at the end of the 
lower arm 13 and is locked at the end of the upper arm by a nut 10. The 
bolt-like bar has two spiral groove-like segments 11,12. The distal 
segment 11 keeps the nut when releasing this device. The proximal segment 
12 is used for changing the distance between opposed jaws in order to 
adjust a desirable hemostatic pressure so that after incising and/or 
excising lip tissues, we can release the device gradually in order to 
easily find out which vessels are still bleeding and then use regular 
hemostatic clamps to easily stop each vessel from bleeding. 
Model B, shown in FIG. 8, comprises a pair of semicircular jaws 14 which 
are curved 90.degree. with a pair of semicircular parts of the arms so 
that the surgeon can have access to the surgical field easily without 
obstacle which may be caused by the arms of the device. This device is 
used for lip surgery which need operation only in a small area as shown in 
FIG. 11. For example: Biopsy, Polype, ect. The arm 19,22 of Model B has 
the sliding hugging system which comprises a channel in the lower arm 22 
and a rod-like segment on the upper arm 19. An enlarged sectional view of 
this system is the same structure as in Model A which is shown in FIG. 5. 
The end of arms is the locking bar system as shown in FIG. 6. This system 
comprises a bolt-like bar 9 which is elongated from the upper arm 19 and 
locked at the end of the lower arm by a nut 10. The bolt-like bar 9 has 
two spiral groove-like segments 11,12 like that of Model A. The 
combination of the sliding hugging system and arm-jaw 90.degree. 
angulation 16 as shown in FIG. 13 is used for keeping constantly parallel 
between two opposed jaws so that we can maintain the constant pressure 
throughout the entire surgical area. 
Model C, shown in FIG. 9, comprises a pair of equal circular jaws 15 which 
are connected with segment 18-20 of the arms so that we can use to operate 
a deep oral surgery on the mucosal side of the cheek. For example: Facial 
dimple making as shown in FIG. 12, biopsy, tumor excision, ect. Model C 
has a pair of 90.degree. angulated arms as shown in FIG. 14. At the end of 
arms is the locking bar system which is the same one of Model B. The 
combination of the sliding hugging system and the 90.degree. angulated arm 
is used for keeping a constantly parallel between two opposed jaws with 
the same purpose of Model B.
