Example 1

Fig. 1 is a novel instrument for female pelvic floor prolapse operation, including handle 1 and puncture main part 2, puncture main part 2 includes flexion and puncture head 4, handle 1 and puncture main part 2 pass through transition portion 3 and connect, the flexion includes first bending section 21 and second bending section 22 and the whole heliciform that is of flexion, the spiral direction of first bending section 21 and second bending section 22 is opposite, puncture head 4 top is equipped with the closed card hole 5 that penetrates the implantation net piece, card hole 5 is oval.

The oval closed clamping hole 5 penetrating into the implanted mesh at the top end of the puncture head 4 can allow a sling implanted into the mesh to directly penetrate into the clamping hole 5 without fixing a guide thread (suture line), thereby facilitating the operation of a doctor in the operation process.

Wherein, the bending part and the puncture head 4 are made of the same material and are formed by one-time processing, and the bending part can also be processed into the shape of the puncture head 4 for two times or more; the bending part is an integrally formed metal round rod, the bending part is made of medical stainless steel in the embodiment, and the diameter phi of the bending part is 3 mm;

transition portion 3 is the toper and respectively with handle 1 and puncture main part 2 fixed connection, transition portion 3 is the same with the surface shape size that handle 1 and puncture main part 2 contacted respectively, handle 1 is the prism, the material of handle 1 is plastics, and transition portion 3's setting can make handing-over department transition more level and smooth nature for handle 1 and puncture main part 2's connection is more smooth and smooth, reduces the puncture resistance in the use, and compares with the connection structure of original right angle type and does not have the disinfection dead angle, therefore the disinfection is more thorough, and foreign matter can effectually be avoided persisting to this kind of structure, can be used repeatedly after abundant disinfection.

According to the dissection of the female pelvic floor, the lower pubic angle of Chinese female is 90-100 degrees, and the distance between ischial tuberosities on two sides is 8.5-9.5 cm.

Therefore, the included angle theta between the bending radian of the bending part and the bending radian of the handle 1 is 40 degrees; the transverse distance L1 between the outermost end of the outer arc surface of the first bending section 21 and the outermost end of the outer arc surface of the second bending section 22 is 60.6mm, and the longitudinal distance L2 is 56.7 mm; the longitudinal length L3 of the first curved section 21 is 23.3mm, and the longitudinal length L4 of the second curved section 22 is 41.4 mm.

Example 2

According to the technical scheme of the utility model, still can obtain an embodiment opposite with the spiral direction of the flexion of embodiment 1, that is to say the spiral direction of first crooked section 21 is the dextrorotation, the spiral direction of second crooked section 22 is the levorotation.

The puncture tool obtained according to this example was used for puncturing the side of the through-hole 6 opposite to that of example 1, and operated in the same manner as in example 1 except for the change of direction.

The application of the puncture tool in operation will be described below by taking the improved anterior pelvic floor reconstruction of a patient with pelvic organ prolapse as an example. The two puncture instruments with different spiral directions in the embodiments 1 and 2 are adopted to respectively puncture the two sides through the obturator 6, the epidural anesthesia is selected as the anesthesia mode, one common fairy mesh produced by the Proteus company of America is adopted, the mesh main body is trimmed into a butterfly-shaped shape, 4 hanging strips (wings) are trimmed at the same time, and the hanging strips are used as guide arms of the butterfly-shaped mesh and respectively penetrate into the clamping holes 5 at the tops of the two puncture heads 4. The operator incises the mucous membrane of the anterior vaginal wall in a longitudinal shape of 2cm below the urethral orifice, frees the bladder, simultaneously keeps the suprapubic cervical fascia of the vaginal wall, and separates the vaginal wall to the two sides in a blunt and sharp manner until the vaginal wall touches the arcus tendineus of the pelvic fascia. The existing positioning and guiding puncture method in the operation is adopted, and the left and the right are respectively used as two skin outlets for placing two groups of braces with different depths. Under an open visual field, two tools of examples 1 and 2 are used for sequentially entering from the outside to the inside from skin outlets on two sides respectively, fingers are used for guiding in the vaginal space of the bladder all the time, and the sling is placed in the body. The placement of the sling at the other three positions on both sides is also done in sequence under the guidance of the fingers. Finally, the butterfly mesh is made to pass through the pubocervical fascia and the arcus tendineus of the pelvic fascia of the anterior pelvic cavity by the path of the obturator 6, forming a hammock type to be placed in the bladder-vaginal space.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
