Abstract
The invention relates to a trivalvular sealing valve for a peritoneocentesis device. The trivalvular sealing device comprises a trivalvular sealing valve body (1); one end of the trivalvular sealing valve body (1) is provided with a connecting edge (3); and the other end of the trivalvular sealing valve body (1) is corrugated and comprises three cuts. The trivalvular sealing valve is characterized in that axially arranged airtight assistant ribs (5) are arranged corresponding to each cut (4) on the inner surface of the valve body (1). The three airtight assistant ribs are beneficial to elimination of the phenomenon that the trivalvular sealing valve has a gap when a cut passage behind the cuts is naturally closed, and further enhances the natural closing performance of the cut passage behind the cuts of the trivalvular sealing valve so as to ensure that the cut passage of the trivalvular sealing valve can be automatically closed when an apparatus is replaced in an operation process; the condition that the cut part of the trivalvular sealing valve turns out backwards along the extraction direction of the apparatus when the apparatus is extracted is prevented; thus, CO2 gas in a human abdominal cavity is protected; and the leakage of the CO2 gas in the human abdominal cavity is effectively prevented.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, especially a kind of three flap seal valves that are used for the abdominal paracentesis device effectively stop the leakage of CO2 gas in the human abdominal cavity in the process of operation replacing apparatus.
Background technology
Present peritoneoscope Minimally Invasive Surgery, general open abdomen before this, an operation passage is built up in the back puncture.The CO2 gas that reinjects is set up the human body pneumoperitoneum, and the doctor carries out laparoscopic surgery under laparoscopically monitoring system.Perforator is made up of several parts such as gas seal assembly, housing, puncture shell and puncture needles.Perforator is used with apparatus in operation, after operation path builds up, when changing apparatus, because the perforator sealing member can't be to the CO2 gas effective seal in the human abdominal cavity, thereby causes Intraabdominal gas to leak.
Summary of the invention
The object of the invention is exactly to change in the process of apparatus in operation in order to overcome existing seal valve, the defective that causes intraperitoneal gas to leak, and a kind of three flap seal valves that are used for the abdominal paracentesis device are provided.
The technical solution adopted for the present invention to solve the technical problems is:
The three flap seal valves that are used for the abdominal paracentesis device; Comprise three flap seal valve bodies, three flap seal valve bodies, one end is provided with adjoining edge, and the other end is wrinkle shape and also has three otch; It is characterized in that: at the inner surface of valve body, corresponding each otch is provided with the airtight auxiliary muscle of axial placement.
Article three, airtight auxiliary muscle has solved there is the slit in three flap seal valves when the otch passage is closed naturally behind otch phenomenon; Further strengthened the closed naturally performance of three flap seal valves otch passages behind otch; Thereby when guaranteeing in operation process, to change apparatus, make three flap seal valve otch passages ability moving closure certainly; Prevent that three flap seal valve notch portion were extracted direction to returning the generation of routing up along apparatus when apparatus from extracting, CO2 gas is protected in the human abdominal cavity thereby make, and has effectively stoped the leakage of CO2 gas in the human abdominal cavity.
On the basis of above-mentioned main technical schemes, can increase following further perfect technical scheme:
Described airtight auxiliary muscle is by the adjoining edge place of outward flange to the valve body of otch.
Outer surface at valve body is provided with one group of reinforcement of axially placing; Outside six reinforcements are extracted direction to returning the generation of routing up along apparatus playing when preventing that apparatus from extracting three flap seal valve notch portion; CO2 gas is protected in the human abdominal cavity thereby make, and when effectively having stoped the leakage effects of CO2 gas in the human abdominal cavity, has increased the bulk strength of three flap seal valves; In preventing to perform the operation apparatus when rotating because the deficiency of three flap seal valve intensity; Cause three flap seal valve bulk deformations, it is come off from compressing the positioning sleeve position, and cause the leakage of intraperitoneal gas when changing apparatus.
Described reinforcement is extended by the adjoining edge place vertically, and keeps a segment distance with incision.
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Description of drawings:
Fig. 1 is a front view of the present invention;
Fig. 2 is a side view of the present invention;
Fig. 3 is a rearview of the present invention;
Fig. 4 is the A-A view of Fig. 1 of the present invention;
Fig. 5 is the embodiments of the invention view.
The specific embodiment
As shown in Figure 1, the present invention is used for three flap seal valves of abdominal paracentesis device, comprises three flap seal valve bodies 1; Three flap seal valve bodies, 1 one ends are provided with adjoining edge 3, and are as shown in Figure 2, and the other end is wrinkle shape and also has three otch 4; The incision wrinkle of three flap seal valves make and are hexahedro inclined-plane around the otch, and are as shown in Figure 4, and the axis direction of each inclined-plane and valve body forms a specific angle β; Increase the active force of intraperitoneal gas pressure to it, when operating theater instruments was changed, apparatus took out from the otch of three flap seal valves; The pressure of intraperitoneal gas on three flap seal valves, six inclined-planes, makes the otch passage closed, as shown in Figure 3 immediately in momentary action at this moment; At the inner surface of three flap seal valve bodies 1 adjoining edge place by outward flange to the valve body of otch; Corresponding each otch 4 is provided with the airtight auxiliary muscle 5 of axial placement, evenly is provided with six reinforcements of axially placing 2 at the outer surface of flap seal valve body 1, and described reinforcement 2 is extended by the adjoining edge place vertically; And keep a segment distance with incision, make the sealing of three flap seal valves reach best effect.
As shown in Figure 5, this device is used for the abdominal paracentesis device, and what the abdominal paracentesis device included fixing three flap seal valves compresses positioning set 6, three flap seal valves, puncturing lever 8, spherical sealing ring 7; The main effect that compresses positioning set 1 is the correct location that guarantees three flap seal valves, stops its free play and end face seal in the axial direction;
When puncturing lever inserts, the otch of three flap seal valves will be opened, and this moment, three flap seal valves did not seal, and leaned on spherical sealing ring sealing, stoped the leakage of intraperitoneal gas; And puncturing lever takes out when changing apparatus; Because the existence of a circular hole passage is arranged on the spherical sealing ring; Spherical sealing ring does not play any sealing function; This moment, Intraabdominal gas pressure acted on three flap seal valve otch, six inclined-planes on every side, and three flap seal valve otch passages this moment rapid auto-closing under self-characteristic and gas load stops the leakage of intraperitoneal gas.
