Further, the protection head 4 is a hemispherical structure made of soft rubber and is arranged at the front ends of the circular cylinder wall 7 and the opening plate 1.
Furthermore, the suction hole 6 is a small-hole-shaped structure channel in front of the circular cylinder wall 7 and at the position of the opening plate 1.
Further, the suction port 9 can be communicated with the suction equipment of the operating room through a suction leather strap; and can communicate with the suction port 6 by a movable control valve 8.
Furthermore, the fixed handle 11 is a handle which is fixed with the cylinder wall 7 through the support rod 10 and is immovable.
Further, the spring 12 is a spring 12 having a tensile force between the fixed handle 11 and the movable handle 13.
This formula of turning up peritoneoscope is with concrete connection structure of tissue exposure ware does: the opening plate 1 is positioned at the front end of the cylinder wall 7 of the instrument, the opening plate 1 is positioned behind the protective head 4, and the opening plate 1 is of a flat, metal and smooth steel plate structure; a slotted structure is arranged on the cylindrical barrel wall 7 at the rear part of the protective head 1, two opening plates 1 which can be movably controlled by the connecting rod 5 are concealed in the slot at the front part of the barrel wall 7; at the slotting position of the cylinder wall 7, two expanding plates 1 are fixed on the cylinder wall 7 by a fixed connection 2, the expanding plates 1 can expand and contract around the fixed connection 2, and a movable connection 3 is a movable axial connection which is connected to the other end of the expanding plates 1 and is connected with a connecting rod 5; when the movable handle 13 is moved forwards, the connecting rod 5 and the movable connection 3 can be driven to enable the opening plate 1 to be turned inwards and to be contracted in the grooved cylinder wall 7; the movable handle 13 is pulled backwards, so that the connecting rod 5 can move backwards, and the movable connection 3 is driven, and the opening plate 1 is outwards turned; the spring 12 is a spring 12 which is connected between the fixed handle 11 and the movable handle 13 and has tension; under natural conditions, the spring 12 can make the opening plate 1 in an outward-turning and opening state; the fixed handle 11 is fixed on the cylinder wall 7 through a support rod 10; there are more, the suction hole 6 of aperture structure at section of thick bamboo wall 7 fluting department, suction hole 6 can communicate with each other with suction port 9 through hollow section of thick bamboo wall 7, and control valve 8 is the moving valve who controls suction port 9 and suction hole 6 and communicate with each other (its structure is similar to the mouth switch of urinating on the medical urine collection bag, and its structure is not the focus and difficult point of this patent, on this patent application material, does not describe in detail).
The tissue exposer for the flip-up laparoscope has the advantages that: when the electric coagulation, the electric excision and the suture operation of tissues are required during the operation treatment under the laparoscope, the spreader plate 1 which can be unfolded in a plane can assist an operator to fully and clearly expose the tissues in an operation area, so that the operation is smoother; particularly, when the rectum tissue at the pelvic cavity is exposed in the laparoscopic rectal cancer operation, the advantage of the instrument is more obvious, and the instrument can be used for well assisting an operator to expose the tissue in the rectal operation area in the narrow pelvic cavity area. Among the rectal cancer operation radical surgery, when the operator separates the pelvic cavity region, operation assistant appears when rectum and surrounding tissue expose not clear, or use the electrotome, when too much smog appears in the supersound sword, can use this surgical instruments to expose and absorb smog, operation assistant, through back-pull movable handle 13, cause connecting rod 5 to pull back, can expand the board 1 that struts of this apparatus, strut board 1 can demonstrate a great tissue plane that exposes, strut board 1 through the expansion, can keep off operating member's in the pelvic cavity tissue, fully expose the operation region, help the operation of operator, and then make things convenient for the operation. Meanwhile, when an operator separates tissues, the electric knife and the ultrasonic knife are used to cause smoke to be generated in an operation area, and when the visual field of an operator is influenced, the smoke in the operation area can be sucked away by using the suction hole 6 arranged on the surgical instrument, so that the clear and identifiable visual field of the operator is kept, and the safety of the operation is further ensured.
The specific use method of the tissue exposer for the flip-up laparoscope comprises the following steps: when an operator separates a narrow pelvic cavity operation area of a patient and an operation area is difficult to expose or the operator separates a rectum area in the narrow pelvic cavity during laparoscopic suture, electrocoagulation and electrotomy treatment, particularly in laparoscopic rectal cancer radical operation, when the operator uses an electrotome and an ultrasonic scalpel to generate excessive smoke and cannot see the operation visual field clearly, the surgical instrument can be used for exposing the operation area and absorbing the smoke in the operation area by using the opening plate 1 and the suction hole 6; the specific using method comprises the following steps: taking the surgical instrument, sucking a leather strap through an operating room by a suction port 9, connecting the surgical instrument with suction equipment, pushing a movable handle 13 forwards, contracting two expanding plates 1 in a grooved cylinder wall 7 behind a protective head 4 under the action of a connecting rod 5, placing the ends of the expanding plates 1 of the surgical instrument into the abdominal cavity of a patient through a puncture sleeve hole established on the abdominal wall of the patient, pulling back the ends of the movable handle 13 of the surgical instrument by an operator outside the abdominal cavity of the patient, expanding the expanding plates 1 in an expanding working state of a laparoscope under the action of the connecting rod 5, keeping the expanding working state under the action of the pulling force of a spring 12, blocking tissues through an expanding plane of the expanding plates 1, and particularly, having more obvious advantages when the surgical instrument is used in the pelvic cavity; when excessive smoke is generated in the operation area by using an electric knife and an ultrasonic knife, the suction apparatus can be opened, the suction hole 6 at the front end of the apparatus is used, the control valve 8 is opened, and the smoke in the operation area is sucked and removed through the suction hole 6, the inner cylinder of the cylinder wall 7, the suction port 9 and suction equipment under the action of small-flow suction. After the operation is finished, the movable handle 13 is pushed forwards, the opening plate 1 is contracted in the grooved cylinder wall 7, and the abdominal cavity can be taken out through the abdominal wall puncture cannula of the patient, so that the operation is finished. Through clinical use, this formula of turning up tissue exposure ware for peritoneoscope, the effectual cooperation art person carries out the tissue in the abdominal cavity and expandes, exposes, and in the radical operation of peritoneoscope rectum cancer, the narrow and small rectum pelvic cavity space region of separation, its advantage is more obvious, can effectual assistance assistant, reduces the operation degree of difficulty, improves the operation security, reduces the operation time, and this apparatus is worth clinical popularization.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
