Abstract

The utility model relates to a knotting device for an intra-cavity suture line in minimally invasive surgery. The knotting device comprises an outer sheath (1) and an inner core (2), wherein the outer sheath (1) is a thin-tube body with a through hole (11); the inner core (2) is a solid-core thin-rod body inserted into the through hole (11) of the outer sheath; a first hook (12) is arranged at the front end of the outer sheath (1); the first hook (12) is matched with the front end face of the inner core (2) and is used for clamping the suture line together with the front end face of the inner core (2) when the inner core (2) extends forward; and a second hook (21) capable of hooking the suture line is arranged on the rear part of the front end face of the inner core (2) matched with the outer sheath (1). The knotting device has the advantages of convenience in operating and good knotting effect; by utilizing the knotting device to knot, the operation time is saved and the operation risk is reduced; and the knotting device is used together with a minimally invasive surgery operator, such as laparoscope, and also is used together with a nipper entering from the other minimally invasive opening, so that the knotting speed is high and the effect is good.

Description

Minimally Invasive Surgery intracavity suture knotter
Technical field
This utility model relates to medical apparatus and instruments, is specifically related to a kind of suture knotter.
Background technology
Little in order to reach the wound that the patient is caused, that brings is painful little, helps the purpose of wound quickly-healing, and the surgery Minimally Invasive Surgery is implemented widely, also can bring the inconvenience on the certain operations thus, for example intracavity suture knotting.The method that adopts at present is under the observation of endoscope, to use tweezers to match respectively through two different Wicresoft's mouths to tie a knot, and both has been not easy to operation, and the knotting effect is bad again, also can increase the risk of operation in the time of the waste operating time.
Summary of the invention
The purpose of this utility model provide a kind of be convenient to operate, tie a knot effective, not only saved operating time but also can reduce the Minimally Invasive Surgery intracavity suture knotter of operation risk.
The technical solution of this utility model is: it comprises epitheca and inner core; Epitheca is the thin tube-like body with through hole; Inner core is the real core thin rod shape body that is through in the epitheca through hole; The front end of epitheca is provided with time hook one that matches, can clamp with the front end face of inner core when inner core protracts suture with the front end face of inner core, and the rear portion of the front end face that inner core matches with epitheca is provided with time hook two that can hook suture.
The technique effect of this utility model is: it has is convenient to operation, and the effective advantage of tiing a knot uses its knotting both to save operating time, can reduce operation risk again.Minimally Invasive Surgery operators such as it and peritoneoscope are used, and match with the tweezers that get into from another Wicresoft's mouth, and knotting speed is fast again, and effect is good again.
Description of drawings
Accompanying drawing is this utility model example structure sketch map.
The specific embodiment
Shown in accompanying drawing; It comprises epitheca 1 and inner core 2; Epitheca 1 is for having the thin tube-like body of through hole 11; Inner core 2 is for being through at the real core thin rod shape body in the epitheca through hole 11, and the front end of epitheca 1 is provided with time hook 1 that matches, can clamp with the front end face of inner core 2 when inner core 2 protracts suture with the front end face of inner core 2, and the rear portion of the front end face that inner core 2 matches with epitheca 1 is provided with time hook 2 21 that can hook suture.
Return hook 1 by the front end that is positioned at epitheca 1, a side and epitheca 1 front end be connected as a single entity, and the transverse sheet that parallels of inner core 2 front end faces constitute.The corner of returning the leading section of hook 1 is circular arc.Return hook 2 21 by constituting returning the cross-peen of between hook 1 and epitheca 1 leading section, laterally being located at inner core 2 leading sections.
Inner core 2 is through in the epitheca 1 during use, and the rear end of epitheca 1 is fixed on the fixed part of operator, and the rear end of inner core 2 is fixed on the movable part of operator; Elder generation's clamping lever during knotting, inner core 2 front end face that protracts withstands on returning on the hook 1 of epitheca 1, hooks suture with time hook 2 21 on the inner core 2; Coiling back release handle; Time hook 1 on the reuse epitheca 1 hooks up the suture of the other end, and clamping lever is clamped the suture tension, and knotting is accomplished.。
