The guide cylinder 11 is cylindrical and is provided with a stepped brim outside of one side and an escape groove 11 a is formed for passing the tube 9 of the endo-bag 1, as shown in FIG. 1, at the end of the brim. The outer diameter of the cylindrical body is set so as to be inserted in the trocar site F (FIG. 1). The endo-bag is folded and contained in the guide cylinder 11 and the tube 9 extending therefrom is led out through the escape groove 11 a.
The push shaft 12 is cylindrical so as to be inserted in the guide body 11 and provided with a brim at both sides of the outer circumference thereof. The outer diameter of one brim is set so as to be inserted in the guide body 11 without having any space. The folded and contained endo-bag 1 in the guide body 11 can be pushed out by inserting the push shaft 12 to the guide body 11 with the side having brim heading forward. An escape groove 12 c is provided for the outer circumference of the brim for escaping the tube 9 extending from the endo-bag 1.
The cap for fixing the bag 13 is used for covering the brim 12 d positioned at the guide pin 12 b side of the push shaft 12. The cap 13 is mainly comprised of an outer body 13 a and an inner body 13 c, both of which are fixed in the axial direction each other and connected rotatably around the axis. Therefore, the outer cap body 13 a can be turned without turning the inner cap body 13 c.
The outer cap body 13 a is cylindrical having a brim in the direction of the inner diameter at one side and the cylindrical body without having the brim is covered on the brim 12 d having the guide pin 12 b of the push shaft 12. The cylindrical body is provided with two guide grooves 13 b which is cut into from the edge and is comprised of a straight groove along the axis and a tapered groove extended from the straight groove. The guide pin 12 b is designed to be inserted into the guide groove 13 b.
The inner cap body 13 c is connected to the inner diameter of the brim of the outer cap body 13 a and a tapered male part 13 d is formed corresponding to the tapered female part 12 a of the push shaft 12. When the push shaft 12 is covered with the cap 13, the tapered female part 12 a and the tapered male part 13 d are designed to be caught each other. An O-ring 13 e is inserted into the groove provided at appropriate parts of the tapered male part 13 d.
The inner diameter of the inner cap body 13 c is formed as an inserting hole 13 f for passing through the shaft of the forceps guide 14 and the forceps without having extra space. A sealing ring 13 g is provided at an appropriate portion of the hole 13 f to achieve sealing function when the forceps is pierced.
The diameter of the inserting hole 15 a is set to fit the outer diameter of the surgical instrument such as a forceps A and extra outside air is prevented from entering when the surgical instrument is inserted or operated. After necessary treatment is finished, the surgical instrument is pulled out and the sealing plug 16 is inserted into the hole 15 a. Therefore, leakage out of the endo-bag 1 and entering of a contaminant from the outside air can be prevented by inserting the sealing plug 16 into the hole 15 a.
FIG. 13 shows another embodiment of the inserting means for an endo-bag 1B according to the present invention. FIG. 13(a) shows a guide cylinder, FIG. 13(b) shows a push shaft, and FIG. 13(c) shows the condition wherein the inserting means for an endo-bag can be inserted. FIG. 13(b) shows its left side view at left and its right side view at right other than the vertical sectional view at center. In FIG. 13(c) shows its right side view at right other than the sectional view showing its usage at left.
The folding lines 1 b are shown as two-dotted lines in the figure, however, they are actually formed on the sheet material of the receptacle portion 1 a as an aim to show a line to be fold. There are folding lines 1 ba which are parallel to the longitudinal direction of the receptacle portion 1 a and line 1 bb which is vertical to the lines 1 ba.
The folding lines 1 ba are formed so as to divide the outer circumference of the receptacle portion 1 a into six portions, the outer circumference of which is perpendicular to the longitudinal direction of the receptacle portion 1 a. In the figure, only one side is seen. The folding lines 1 ba are only an aim to fold the endo-bag 1C when it is inserted in the guide cylinder, as mentioned hereinafter. The outer circumference is divided into six in this case, however, the number is appropriately set according to how the bag is folded.
The folding line 1 bb is an aim to fold the back of the line 1 bb of the receptacle portion 1 a into the organ receiving mouth 3 side and is formed around the outer circumference in the direction perpendicular to the longitudinal direction of the receptacle portion 1 a.
The angle α defined by the inserting portion for a surgical instrument 4 and the longitudinal center line of the receptacle portion 1 a isn't shown in the endo-bag 1 in FIG. 2, however, it is 150°˜160°. The angle α of the endo-bag 1C is 90°˜100°. The reason of setting such an angle is as follows. As shown in FIG. 21(k) and FIG. 22(l), when the endo-bag 1C is set in the abdominal cavity, the positional relation between the inserting portion 4 and the organ receiving mouth 3 conforms to the relation between the trocar sites to be formed respectively so that the endo-bag 1C has no slag and wrinkles on operation.
The grip plug 11B isn't used in case of the guide cylinder of FIG. 10 and is inserted in the guide cylinder 11A. It is provided with a rounded point 11Ba at its point, a grip 11Bb at an end for easy holding. It is so designed to be easily operated by holding it when it is inserted in the guide cylinder 11A and to be easily inserted in the trocar site because of the rounded point 11Ba.
The guide cylinder 11A is designed so as to be inserted in the trocar site without difficulty because of a spiral 11Aa provided for its outer diameter comparing to the guide cylinder 11 of FIG. 10. An O-ring 11Ab for sealing is provided for its inner diameter so as to be kept airtight when the grip plug 11B is inserted.
The pipe guide 12B is cylindrical and has a thick portion where the half length of the pipe guide 12B is attached with the tip end of the push shaft 12 and a male screw 12Ba is provided for the outer diameter of the thick part. An escape groove 12Bb for freely attaching the tube 9 of the endo-bag 1C and 1D is provided along the whole length of the cylinder including the male screw 12Ba.
The cap for folding 12C of FIG. 29(c) is a thin cylinder and is provided with a female screw 12Ca which is screwed into the male screw 12Ba of the pipe guide 12B at the inner diameter. The cap 12C is designed to cover the folded endo-bag 1C and 1D set at the tip end of the pipe guide 12B so as to keep the folding of the bag at its root. The cap 12C may be screwed until the connection is removed by screwing into the male screw of the pipe guide 12B and may be screwed back for this purpose. Otherwise, the cap 12C may be incorporated from the tip of the folded endo-bag 1C, 1D and may be used by screwing into the male screw 12Ba of the pipe guide 12B.
An outer cap 13Aa having a guide groove 13Aaa is the same as the outer cap 13 a of the bag fixing cap 13 in FIG. 10. The guide projection 12Ac of the push shaft 12A is designed to be inserted in the guide groove 13Aaa of the outer cap 13Aa.
The forceps guide 14A of FIG. 30(b) is comprised of a brim 14Aa, a bottom 14Ab, and a pipe shaft 14Ac like the forceps guide 14 of FIG. 10 and has the same function such as the forceps guide 14.
The contacting part of the guide cylinder 11A on the trocar site F isn't straight, unlike the guide cylinder 11 of FIG. 18, and is formed as spiral 11Aa like a usual trocar. Accordingly, the guide cylinder 11A doesn't apply extra pressure on the abdominal wall E by rotating to be inserted into the trocar site F. Further, it is prevented from entering the outside air by means of the grip plug 11B. The grip plug 11B can be operated effectively when inserted in the trocar site F because it is turned together with the guide cylinder 11A by the operation of turn-stop parts 11Ac and 11Bc.
When the guide cylinder 11A is inserted into a fixed portion and the endo-bag 1C is prepared, the grip plug 11B is removed and the prepared endo-bag 1 is quickly inserted in the guide cylinder 11A as shown in FIG.36(h).
