Problems solved by technology

However, since the tube is flexible, it will be crushed (compressed) by the stripped living tissue
As a result, even if the insertion operation of the sling is performed, the insertion operation may become difficult due to the friction between the tube and the living tissue.

[0055] Figure 1 to Figure 11 are respectively sectional views sequentially showing the usage method of the first embodiment of the medical tube (medical tube assembly) of the present invention, Figure 12 From figure 1 The figure (side view) observed in the direction of arrow A in Figure 13 yes Figure 7 The BB line sectional view in Figure 14 yes Figure 7 The sectional view of line C-C in Figure 15 From Figure 7 ((a) shows the state before the separation part is separated, and (b) shows the state after the separation part is separated). In addition, for the convenience of explanation below, the Figure 1 to Figure 12 in (for Figure 17 ~ Figure 19 Similarly) the upper side is referred to as "upper" or "upper", and the lower side is referred to as "lower" or "below". In addition, the needle tip side is called "tip end", and the opposite side is called "basal end".

[0119] Figure 16 It is a cross-sectional view showing a second embodiment of the medical tube (medical tube assembly) of the present invention.

[0120] Hereinafter, a second embodiment of the medical tube and the medical tube assembly of the present invention will be described with reference to this figure, but differences from the above-mentioned embodiment will be mainly described, and description of the same items will be omitted.

[0121] This embodiment is the same as the first embodiment except that the number of cavities formed is different.

[0122] Such as Figure 16 As shown, in the medical tube 2A of this embodiment, in addition to the lumen 25 into which the implant 8 is inserted, a lumen 26 into which the guide wire 40 is inserted is also formed. The lumen 25 and the lumen 26 are formed independently of each other. This prevents the implant 8 from interfering with the guide wire 40, so that, for example, the guide wire 40 can be inserted and removed smoothly....

[0125] Figure 17 ~ Figure 19 Each is a cross-sectional view sequentially showing the method of use of the third embodiment of the medical tube (medical tube assembly) of the present invention.

[0126] Hereinafter, a third embodiment of the medical tube and the medical tube assembly of the present invention will be described with reference to these drawings, but differences from the above-mentioned embodiment will be mainly described, and descriptions of the same items will be omitted.

[0127] This embodiment is the same as the first embodiment except that the separation part is omitted from the medical tube.

[0128] Such as Figure 17 , Figure 18 As shown, the medical tube 2B of the present embodiment omits the separating portion 235 that the medical tube 2 of the first embodiment has.

[0129] In addition, the distal end portion 81 of the implant 8 protrudes from the distal opening portion 21 of the medical tube 2B in advance.

[0130] As an example of the usage method...

Abstract

Provided are a medical tube and a medical tube assembly which enable an implant to be easily and reliably inserted and placed in a living body. The medical tube (2) has an elongated implant (8) inserted therein. The medical tube (2) is composed of a tube having a tip opening (21) wherein the tip is open, and a base end opening (22) wherein the base end is open. Moreover, the middle of the tube is curved in the longitudinal direction, and the tube has a curved section (231) in which a curved shape is maintained.

Description

technical field [0001] The present invention relates to a medical tube and a medical tube assembly. Background technique [0002] Urinary incontinence, especially abdominal pressure incontinence, causes abdominal pressure to be exerted during normal exercise, laughing, coughing, sneezing, etc., resulting in leakage of urine. The reasons for this include, for example, relaxation of the pelvic floor muscles, which are muscles supporting the urethra, due to childbirth or the like. [0003] Surgical treatment is effective in the treatment of urinary incontinence, such as the use of a strip-shaped implant called a "sling", which is left in the body and supports the urethra with the sling (see for example the patent Literature 1). To place the sling in the body, the operator cuts the vagina with a scalpel, peels off the living tissue between the urethra and the vagina, and uses a puncture needle to form a puncture hole that communicates with the stripped living tissue and the ou...
