Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to a disposable delivery guide. Background Art

[0002] Currently, mesh implantation is used in female pelvic organ prolapse to help the prolapsed organs return to their normal physiological position. The design concept of this product is to help the mesh pass through muscle fascia and other tissues so that the mesh can be implanted into the human body. The existing technology uses a stainless steel puncture needle to drive the mesh belt to puncture the human tissue for fixation.

[0003] The use of stainless steel puncture needles has the problem of being too short, which increases the difficulty of surgery. Since the stainless steel puncture needle is one-piece, it needs to be made into an arc to adapt to the female pelvic structure, but the puncture may not be in place, and the doctor needs to expand the anatomical area and manually pass through the mesh belt, which increases the surgical wound surface, causes greater trauma to the patient, and also increases the difficulty of surgery. The handle is also made of stainless steel. The smooth handle leads to less resistance, and there is a risk of the handle slipping during puncture. Summary of the invention

[0004] Based on the technical problems existing in the background technology, the present invention proposes a disposable delivery guide having the functions of puncture and delivery guidance. The curvature of the stainless steel hook is more in line with the requirements of the female pelvic anatomical structure, effectively reducing the trauma to the patient.

[0005] The present invention provides a disposable delivery guide, comprising a guide body, the guide body comprising a handle, a slider, a stainless steel hook and a lasso, the handle being placed horizontally, the handle being composed of a cylinder and a truncated cone from left to right, the central axes of the cylinder and the truncated cone being arranged horizontally, the top of the upper left corner of the cylinder being arranged obliquely, the middle of the handle being a cylinder with a horizontally arranged central axis, the rightmost end of the handle being a truncated cone, a slide groove being horizontally provided on the top of the handle, the slide block being slidably installed in the slide groove; the stainless steel hook being connected to the left end of the handle, the stainless steel hook being composed of five parts, the rightmost end of the stainless steel hook being the central axis The cylinder 1 is arranged horizontally with its axis, the left end of the cylinder 1 is connected to an arc segment 1, the center of the arc segment 1 is at the lower right corner of the arc segment 1 itself, the left end of the arc segment 1 is connected to the arc segment 2, the center of the arc segment 2 is above the arc segment 2 itself, the arc segment 1 and the arc segment 2 are both hollow three-dimensional structures, the curvature radius of the arc segment 2 is smaller than the curvature radius of the arc segment 1, and the left end of the arc segment 2 is connected to the sleeve upward; the lasso is obliquely inserted into the sleeve, the lasso is connected to the handle through a steel wire, the steel wire is arranged inside the stainless steel hook, the end of the steel wire is located inside the handle and connected to the slider, and an alloy clip is arranged in the lasso. The handle and the slider cooperate with each other to increase the length of the introducer body, so that the doctor can more conveniently insert the mesh belt, and the sleeve is made of polytetrafluoroethylene material, which is currently recognized as the smoothest material in the world, ensuring smoothness during puncture.

[0006] Furthermore, the alloy clip is a nickel-titanium alloy clip. The nickel-titanium alloy clip has a memory function, which ensures that it does not deform during puncture and avoids damage to human tissues around the operation.

[0007] Furthermore, a handle is installed at the bottom of the lower right corner of the handle, and the installation of the handle facilitates the operation of the introducer body by holding it.

[0008] Furthermore, a handle is provided on the slider, which facilitates the movement of the slider, thereby facilitating the control of the steel wire through the slider, and further controlling the retraction and extension of the lasso, i.e., the nickel-titanium alloy clip.

[0009] Furthermore, the sleeve is a polytetrafluoroethylene tube. Since the polytetrafluoroethylene material used in the polytetrafluoroethylene tube has a smooth material, the smoothness of the introducer body during the puncture process is ensured.

[0010] The advantages of the disposable delivery guide provided by the present invention are as follows: the disposable delivery guide provided in the structure of the present invention, by designing the puncture site to be a part composed of a lasso and a sleeve, the lasso can be extended by sliding a handle slider on the handle, thereby increasing the overall length of the instrument, so that the doctor can more conveniently insert the mesh belt; the lasso is made of nickel-titanium alloy material, which has a memory function, ensuring that it does not deform during puncture and avoiding damage to human tissues around the operation; the sleeve is made of polytetrafluoroethylene material, which is currently recognized as the smoothest material in the world, ensuring smoothness during puncture.
