Description

Knot pusher and laparoscopic surgery tourniquet for laparoscopic surgery tourniquet

Technical field

The utility model belongs to laparoscopic surgical instruments technical field, and in particular to one kind is used for laparoscopic surgery tourniquet Knot pusher and laparoscopic surgery tourniquet.

Background technique

Existing laparoscopic surgery Hemostasis mainly has electric coagulation hemostasis, the hemostasis of drug vasoconstriction, instrument hemostasis etc., In Wherein have in instrument hemostasis one is being stopped blooding using tourniquet, is that tourniquet is sent into abdominal cavity from laparoscope channel, doctor passes through Operate instrument across laparoscope channel it is intraperitoneal tourniquet knot tighten, advantage be suitable for biggish blood vessel or When can not be stopped blooding with other methods, the disadvantage is that instrument of the doctor by operation across laparoscope channel brings hemostasis into intraperitoneal Row knots and tightens, inconvenient for operation, and tourniquet knotting is difficult, spends the time, operating time is caused to extend, and increases operation risk, Additionally, due to being by laparoscope channel in intraperitoneal operation, doctor tighten tourniquet it is also bad firmly tourniquet is difficult to tighten, Cause tourniquet haemostatic effect not good enough.

Utility model content

The purpose of this utility model be it is in view of the above problems and insufficient, a kind of tourniquet knotting is provided and tightens operation Knot pusher and laparoscopic surgery tourniquet for laparoscopic surgery tourniquet convenient, haemostatic effect is good.

In order to achieve the above objectives, it is adopted the technical scheme that:

A kind of knot pusher for laparoscopic surgery tourniquet for the lock head on push-tight hemostasis band body, including pushes away Bar is tied, the end of ligaturing rod is equipped with handle, and the front end of ligaturing rod is equipped with knot end, and ligaturing rod is fixed with handle, knot end Connection, the laparoscopic surgery tourniquet includes tourniquet and the lock head that tourniquet one end is arranged in, the knot end Middle part side be equipped with front and back transition groove, the lug boss of the front end side of the knot end is equipped with tourniquet card slot, institute The side opening of tourniquet card slot is stated, the front end of the tourniquet card slot extends through the front end face of knot end, the tourniquet The thickness of card slot is greater than the thickness of hemostasis band body, and the thickness for the lock head being less than on hemostasis band body.

As the preferred technical solution of the utility model, outer diameter≤5mm of the ligaturing rod.

As the preferred technical solution of the utility model, the ligaturing rod is structure as a whole with knot end setting.

As the preferred technical solution of the utility model, the front and back transition groove is cambered surface groove.

A kind of laparoscopic surgery tourniquet being used cooperatively with above-mentioned knot pusher, including hemostasis band body and setting are only The lock head of blood band body one end, a side surface of the hemostasis band body are equipped with unidirectional helical teeth, and lock head is equipped with through-hole, Latch head through-hole in be equipped with and hemostasis band body on the matched barb of unidirectional helical teeth, it is described hemostasis band body length >= 35cm。

As the preferred technical solution of the utility model, the width of the hemostasis band body is 2~4mm.

By adopting the above technical scheme, acquired beneficial effect is:

The utility model overall construction design is reasonable, by the way that the longer laparoscopic surgery tourniquet of length, Yi Sheng is arranged When operation, one end of hemostasis band body can be introduced abdominal cavity from laparoscope channel, then allow it in the organ position that needs stop blooding It sets and it is drawn into abdominal cavity from laparoscope channel again after a circle, then the one end for the band body that stops blooding is inserted by doctor outside abdominal cavity It latches in head, knots convenient and efficient, then doctor holds one end of hemostasis band body on one side, on one side pushing away by the utility model Head will be latched from laparoscope channel push-in abdominal cavity by tying device, continue to press on lock head by knot pusher, and until that will stop blooding, position is tightened, Because doctor can conveniently exert oneself in external one end for tensing hemostasis band body and with knot pusher push-tight, great efforts, laparoscope hand Art tourniquet tightens securely, and haemostatic effect is good；In addition the side opening of tourniquet card slot, can be directly clamped among tourniquet from side On ontology, so can not only push and lock from single laparoscope channel when pushing lock head using the knot pusher of the utility model Discount, knot pusher can also enter the hemostasis band body of stuck lock discount front end again behind abdominal cavity from the laparoscope channel of other positions Push lock head that can use that is, when the ligaturing rod of a knot pusher pushes the angle inconvenience of lock head from another The knot pusher that laparoscope channel enters pushes, using flexible.
