Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
The abdominal cavity object fetching bag shown in figures 1-5 comprises a bag opening 1, a bag body 2, a drainage tube 3 and a support piece;
the bag opening 1 is a circular closed air bag made of airtight materials, a connecting rope 8 is annularly arranged on a semicircle inside the bag opening, and a metal wire 7 connected with the connecting rope 8 in an end-to-end mode is annularly arranged on the other semicircle; one end of the metal wire 7 is connected with the bag opening 1, and the other end extends out of the bag opening 1; the bag opening 1 is communicated with an air bag connecting pipe 9;
the bag body 2 is arranged at the lower end of the bag opening 1, the drainage tube 3 is arranged on the inner wall of the bag body 2, one end of the drainage tube 3 extends out of the bag body 2, and the drainage tube 3 positioned in the bag body 2 is provided with a tube hole 4; the pipe hole 4 is preferably arranged on the drainage pipe 3 positioned at the bottom area of the bag body 2;
the support comprises two arc guide wires 5 with lower end parts arranged side by side; the upper ends of the two guide wires 5 are respectively connected with the two ends of the metal wire 7 positioned in the bag opening 1; the lower ends of the two guide wires 5 are respectively provided with a limiting net 6, and one guide wire 5 passes through the limiting net 6 of the other guide wire 5. In order to reduce the volume, the supporting piece is directly arranged in the drainage tube 3, the drainage tube 3 is communicated with a drainage connecting tube 10 arranged outside the bag body 2, and the drainage connecting tube 10 is connected with negative pressure drainage equipment; the upper end of the guide wire 5 is connected with the metal wire 7 after passing through the drainage tube 3. The metal wire 7 and the guide wire 5 of the embodiment have certain toughness, so that the bag opening 1 and the bag body 2 can be opened, and meanwhile, the metal wire and the guide wire can be bent, so that the metal wire and the guide wire can be pulled straight to pass through the abdominal cavity opening.
As shown in fig. 2 and 3, the cavity fetching bag further comprises a plurality of elastic plugs 11; the bag opening 1 where the guide wire 5 is connected with the metal wire 7 and the bag opening 1 where the metal wire 7 extends are respectively plugged. The elastic plug 11 comprises a plug body 12 which is plugged and fixed on the bag opening 1 and an elastic rubber block 13 which is embedded in the plug body 12; the guide wire 5 or the metal wire 7 passes through the elastic rubber block 13; the elastic rubber block 13 is in a circular truncated cone shape. As shown in fig. 3, when the metal wire 7 is pulled outwards (towards the right direction in fig. 3), the metal wire 7 extrudes the elastic rubber block 13 at the bending part, and the elastic rubber block 13 is extruded and deformed to change the direction of the hole in the elastic rubber block 13 through which the metal wire 7 passes, so that the metal wire 7 can be smoothly pulled out of the elastic plug 11, and the air bag sealing performance of the bag opening 1 is also ensured.
As shown in fig. 3, a ring or a hole is arranged on the metal wire 7 positioned in the bag opening 1 near the position where the metal wire penetrates out of the bag opening 1, and the connecting rope 8 is wound on the ring or the hole at one end of the metal wire 7 extending out of the bag opening 1 for less than or equal to two circles and then extends out of the bag opening 1; the bag mouth 1 is provided with a rubber plug 15 at the extending part of the connecting rope 8.
As shown in fig. 4, 5, 6 and 7, the abdominal cavity object obtaining bag further comprises a rubber sleeve 16, the rubber sleeve 16 is arranged in the drainage tube 3, the rubber sleeve 16 is sleeved on one end of the two arc guide wires 5 far away from the metal wire 7 and extending out of the bag opening 1, one end of the rubber sleeve 16 is in seamless connection with the arc guide wires 5, the other end of the rubber sleeve 16 is in seamless connection with the tube wall of the drainage tube 3, the tube hole 4 formed in the drainage tube 3 is located between the rubber sleeve 16 and the arc guide wires 5 without the rubber sleeve 16, and the rubber sleeve 16 plays a role in blocking so as to prevent tissues from flowing to the left end (in the direction shown in the drawing).
The length of the metal wire 7 in the bag opening 1 is less than or equal to half of the circumference of the bag opening 1. The metal wire 7 automatically expands into an arc shape due to its elasticity after being inserted into the abdominal cavity through the abdominal cavity opening, so that the bag mouth 1 is formed,
in order to expand the bag opening 1 to be larger, the air bag connecting pipe 9 is connected with the air pumping and delivering equipment, the air bag is inflated by inflating the bag opening 1, the bag opening 1 is in a circular ring shape, the bag opening 1 is the largest at the moment, the air pumping and delivering equipment can be adjusted to deliver air pressure according to needs to adjust the inflation quantity of the bag opening 1, and therefore the caliber of the bag opening 1 is adjustable.
The bag also comprises a handle 14; the metal wire 7 extends out of the bag opening 1 and is connected with a handle 14. To reduce the number of abdominal openings, both the balloon connector 9 and the drainage connector 10 are located near the point where the wire 7 extends out of the pouch mouth 1. Preferably, the balloon connection tube 9 and the drainage connection tube 10 are arranged on the side of the handle 14.
In order to adapt to different operations, a string bag is further sleeved in the bag body 2 of the abdominal cavity object fetching bag. The cut tissue is separated from the tissue fluid under the action of the net bag, which is more beneficial to the drainage tube 3 to absorb the tissue fluid.
During the use, oppress the abdominal cavity thing bag to the volume minimum earlier, for example sack 1 is in non-inflation state, and two seal wires 5 promote each other and make two seal wires 5 region as much as possible for form side by side, and because the special design of this embodiment, two seal wires 5 will be side by side with wire 7 after side by side to whole abdominal cavity thing bag body 2 volume of getting is in the minimum state, is similar to the bar-like, can be very convenient insert the abdominal cavity through the abdominal cavity opening. After the bag opening 1 and the bag body 2 of the abdominal cavity object fetching bag enter the abdominal cavity, the bag opening 1 is automatically formed due to the elasticity of the metal wire 7, and the two guide wires 5 are separated under the elastic action of the metal wire 7, so that the bag body 2 at the lower end is separated; if the bag mouth 1 needs to be further expanded, the bag mouth 1 can be inflated to regulate the diameter. After the negative pressure drainage device is pneumatic, the tissue fluid in the bag body 2 can be sucked out of the bag body 2 through the drainage tube 3; because the guide wire 5 is arranged in the drainage tube 3 and is connected with the metal wire 7, when the curvature of the metal wire 7 is adjusted, the guide wire 5 can be driven to move, the limiting net 6 at the lower end of the guide wire 5 slides in the drainage tube 3, the tissue which is easy to block the tube hole 4 in the drainage tube 3 is pushed away from the tube hole 4, a good dredging effect is achieved, and the operation can be directly completed through the handle 14. The specific pipe hole 4 is dredged as shown in schematic diagrams 6 and 7, a certain pipe hole 4 in fig. 6 is blocked by partial tissues, a certain tissue fluid is also contained in the drainage tube 3, at the moment, only the guide wire 5 needs to be pulled, so that the limiting net 6 moves along with the movement of the guide wire and causes the fluctuation of the tissue fluid, the tissue at the pipe hole 4 can be jacked open by the force generated when the tissue fluid fluctuates to realize the dredging, meanwhile, the tissue can be directly pushed away through the limiting net 6, and the tissue falls to the bottom of the drainage tube 3 as shown in fig. 7; the pipe hole 4 is dredged, and the fallen tissue particles can be crushed under the mutual extrusion action of the two limiting nets 6 and then sucked out.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent replacements, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
