The utility model is suitable for a peritoneoscope appendectomy, simple structure, convenient to use has solved the problem that the swollen appendix can't take out through the hole that the peritoneoscope punctured the sheath.

Description

Appendix extractor convenient for taking out swollen appendix

Technical Field

The utility model relates to the field of surgical instruments, in particular to an appendix extractor convenient for taking out a swollen appendix.

Background

With the continuous improvement of medical level, patients who adopt a laparoscope to carry out minimally invasive surgery recover faster after surgery and have fewer complications. Laparoscopic appendectomy has a smaller incision and a lower chance of postoperative infection than traditional open appendectomy.

However, if the patient has an excessively swollen appendix which is too bulky during the operation, it is difficult to grasp the excised appendix with laparoscopic forceps and remove it through the narrow bore of the laparoscopic puncture sheath. The excised appendix is susceptible to rupture by compression when it passes through the narrow bore of a laparoscopic puncture sheath, causing pus to leak into the abdominal cavity, and resulting in abdominal infection.

Disclosure of Invention

The utility model aims at overcoming the defects of the prior art, providing the appendix extractor convenient for taking out the swollen appendix, and solving the problem that the present celioscope appendix extraction is difficult to take out the swollen appendix through celioscope forceps clamps.

The technical scheme of the utility model is that: an appendix extractor convenient for taking out a swollen appendix comprises an appendix accommodating bag, an end cover, a sleeve and a pull rod;

the appendix collecting bag is arranged between the end cover and the sleeve and comprises a C-shaped elastic bone strip and an elastic outer film; the number of the C-shaped elastic bone strips is not less than three, all the C-shaped elastic bone strips are distributed annularly, one end of each C-shaped elastic bone strip is connected to the end cover, the other end of each C-shaped elastic bone strip is connected to the opening of the front end of the sleeve, and all the C-shaped elastic bone strips surround to form a containing space for containing the appendix; the elastic outer film is connected to all the C-shaped elastic bone strips and surrounds the accommodating space, an opening for accommodating the appendix into the accommodating space is arranged between the elastic outer film and the C-shaped elastic bone strips, and the opening is positioned at one end of the elastic outer film close to the sleeve;

one end of the pull rod is connected to the end cover, and the other end of the pull rod penetrates through the accommodating space, the pipe orifice at the front end of the sleeve and the inner hole of the sleeve and extends out of the pipe orifice at the rear end of the sleeve.

The utility model discloses further technical scheme is: the number of the C-shaped elastic bone strips is four.

Compared with the prior art, the utility model have following advantage:

1. the appendix collecting bag is suitable for celioscope appendectomy, simple in structure and convenient to use, the cut appendix is collected in the appendix collecting bag, then the appendix is taken out through the inner hole of the celioscope puncture sheath, and in the taking-out process, the appendix collecting bag can adapt to the inner hole aperture of the celioscope puncture sheath and is adaptively deformed, so that the problem that the swollen appendix cannot be taken out through the inner hole of the celioscope puncture sheath is solved.

2. In the process of taking out the appendix, even if the appendix is crushed, the pus is completely remained in the appendix accommodating bag, the abdominal cavity cannot be polluted, and the risk of abdominal cavity infection caused by appendix crushing is avoided.

The invention is further described below with reference to the figures and examples.

Detailed Description

Example 1:

as shown in figures 1-2, the appendix extractor for facilitating the extraction of the enlarged appendix comprises an appendix accommodating bag, an end cover 2, a sleeve 3 and a pull rod 4.

The appendix receiving bag is arranged between the end cover 2 and the sleeve 3 and comprises a C-shaped elastic bone strip 11 and an elastic outer film 12. The quantity of C shape elasticity bone strip 11 is four, and all C shape elasticity bone strips 11 are the annular and distribute, and one end is all connected on end cover 2, and the other end is all connected in sleeve pipe 3's front end mouth of pipe department, and all C shape elasticity bone strips 11 surround and form the accommodation space 5 that is used for accomodating the appendix. The elastic outer film 12 is connected to all the C-shaped elastic bone strips 11 and surrounds the accommodating space 5, an opening 6 for accommodating the appendix into the accommodating space 5 is arranged between the elastic outer film 12 and the C-shaped elastic bone strips 11, and the opening 6 is positioned at one end of the elastic outer film 12 close to the sleeve 3.

One end of the pull rod 4 is connected to the end cover 2, and the other end of the pull rod passes through the accommodating space 5, the front end pipe orifice of the sleeve 3 and the inner hole of the sleeve 3 and extends out of the pipe orifice at the rear end of the sleeve 3.

Brief description the utility model discloses a use:

referring to FIG. 3, the operator holds the rear end of the cannula 3 and feeds the appendix receiving bag into the patient's abdominal cavity 8 through the internal bore of the laparoscopic puncture sheath A71. The C-shaped elastic bone strip 11 can be deformed when passing through the inner hole of the laparoscope puncture sheath A71, so that the appendix accommodating bag becomes long and narrow as a whole, and the appendix accommodating bag can pass through the inner hole of the laparoscope puncture sheath A71 smoothly.

Referring to fig. 4, after the appendix accommodating bag enters the abdominal cavity of the patient, the tension rod 4 pulls all the C-shaped elastic bone strips 11 to deform synchronously, so that the accommodating space 5 is expanded, and the opening 6 is expanded and opened along with the expansion of the accommodating space 5. Laparoscopic forceps (not shown) are then introduced through the inner bore of the laparoscopic puncture sheath B72 into the abdominal cavity 8 of the patient, and the severed appendix is introduced into the receiving space 5 through the opening 6.

After the appendix is sent into the accommodating space 5 through the opening 6, the pull rod 4 is loosened to restore all the C-shaped elastic bone strips 11 to a natural state, so that the appendix is fully wrapped in the accommodating space 5, then the rear end of the sleeve 3 is held by hand, and the appendix accommodating bag is taken out from the abdominal cavity of a patient through an inner hole of a laparoscope puncture sheath A71.

In the process, on one hand, the appendix-containing sac can generate adaptive deformation so as to smoothly pass through the inner hole of the laparoscopic puncture sheath A71, and on the other hand, even if the appendix is crushed, pus is completely remained in the appendix-containing sac, and the abdominal cavity is not polluted.

Claims

1. Appendix extractor convenient to swell appendix and take out, characterized by: comprises an appendix accommodating bag, an end cover, a sleeve and a pull rod;

2. The appendix extractor of claim 1 for facilitating removal of the enlarged appendix by: the number of the C-shaped elastic bone strips is four.
