Abstract
The utility model discloses an instrument for abdominal puncture intubation. The instrument comprises a sheath consisting of two semi-tubular bodies connected with each other. The sheath of the instrument for abdominal puncture intubation can be easily torn apart, i.e. the sheath can be separated to two parts and removed from the abdomen, so that the sheath can be easily extracted from the abdomen without influencing the fixed drainage tube and with little trauma.
Description
Technical field
This utility model relates to the surgical clinical operating theater instruments, relates in particular to a kind of abdominal paracentesis tube placing operation apparatus.
Background technology
The abdominal paracentesis tube placing operation is surgical clinical a kind of means and method for the treatment of disease commonly used, and it can be used for the ventricles of the brain-intraperitoneal drainage.Cranium brain numerous disease all can cause " hydrocephalus ", and when hydrocephalus took place, brain increased because of the volume that accumulates in a large number of cerebrospinal fluid, and cerebral tissue can cause the generation of a series of nervous symptoms because of the increase of brain pressure.Need the row ventricles of the brain-intraperitoneal drainage art to subtract low intracranial pressure thus, cerebrospinal fluid absorbs by abdominal tissue (peritoneum, big omentum minus) again simultaneously, and this operation art formula has been a very sophisticated method.Requiring drainage tube should place in the omentum minus capsule in process of clinical application or implant in free abdominal cavity, but at present clinical, all adopt blind method of wearing placement both at home and abroad, is rule of thumb to puncture and place mostly; Do not have simultaneously yet good, more accurately, visual pricking device; And the trocar sheath of puncture usefulness is difficult for taking out after placement.Need be in operation, the limit is toward treatment with external measures, and tube wall is cut off with pliers in the limit, has increased operating difficulty.
The utility model content
The purpose of this utility model is to provide a kind of wound little, operation, abdominal paracentesis tube placing operation apparatus convenient to remove.
For achieving the above object, the technical solution of the utility model is:
A kind of abdominal paracentesis tube placing operation apparatus has trocar sheath, and described trocar sheath is formed by connecting by two semicanal bodies.
State that be provided with in the trocar sheath tube wall can ccontaining fibre-optic through hole.
Described trocar sheath is provided with the annular stop device outward.
Described two semicanal bodies have a hand-held handle of tearing respectively.
The joint face of described two semicanal bodies is concavo-convex to match or two semicanal body junction outer surface cover films.
Described stop medial wall has anti-skidding stricture of vagina.
Described stop is provided with an opening, and described opening is by the latch-up structure closure.
Described latch-up structure is made up of gim peg and lock hole.
Described trocar sheath is made by medical macromolecular materials, and its internal diameter is 2-30mm, and length is 20-300mm, is preferably internal diameter 3mm, length 3.2mm.
Described annular stop device is made by medical macromolecular materials, and its internal diameter is 2-30mm, highly is 1-3cm, and thickness 0.5-2cm is preferably internal diameter 3.2mm.
Described trocar sheath sidewall is provided with scale outward.
Abdominal paracentesis tube placing operation apparatus described in the utility model, trocar sheath two parts easily openable, promptly trocar sheath is separated into two halves and deviates from from the abdominal cavity, make trocar sheath take out from the abdominal cavity easily, and do not influence fixed drainage tube, and wound is little; Be provided with the through hole parallel with trocar sheath in the trocar sheath sidewall, this through hole can penetrate optical fibers, observes situation in the abdomen by the peritoneoscope display system, realizes visual puncture; The stop that trocar sheath is outer can be adjusted the position that it is positioned at trocar sheath as required, realizes localised puncture, uses in the instrumentation process at this abdominal paracentesis tube placing operation, and stop can play the effect of stablizing trocar sheath, prevents that trocar sheath from ftractureing during insertion.

The specific embodiment
See also Fig. 1-4, a kind of abdominal paracentesis tube placing operation apparatus has trocar sheath 1, and described trocar sheath is formed by connecting by two semicanal bodies, and each semicanal body has hand-held 3 concavo-convex matching of joint face of tearing 2, two semicanal bodies of handle, indentation.Described trocar sheath is provided with annular stop device 4 outward, the stop medial wall has anti-skidding stricture of vagina, utilize anti-skidding stricture of vagina to prevent that stop from sliding on trocar sheath, described stop is provided with an opening, described opening is by the latch-up structure closure, described latch-up structure is made up of gim peg 5 and lock hole 6, and stop can be adjusted the position that it is positioned at trocar sheath as required.Be provided with the through hole parallel with trocar sheath 7 in the described trocar sheath sidewall, sidewall is provided with scale outward.
See also Fig. 5, the joint face of two semicanal bodies is concavo-convex to match, and is the buckle shape, sees also two semicanal bodies of Fig. 6 junction outer surface cover film, this thin film top band groove.
Described trocar sheath is made by medical macromolecular materials, and its internal diameter is 3mm, and length is 3.2mm.Described annular stop device is made by medical macromolecular materials, and its internal diameter is 3.2mm, highly is 2cm, thickness 1cm.
See also Fig. 7, when implementing puncture, puncture needle 8 is penetrated trocar sheath, puncture needle is made by rustless steel or medical macromolecular materials, and its diameter is 3mm, matches with the internal diameter of trocar sheath.
In abdominal paracentesis tube placing operation implementation process, carry out visual location as need, then can be with the through hole insertion abdominal cavity of special optical fibers monofilament by the trocar sheath sidewall, see situation in the abdomen on the peritoneoscope display system, drainage tube is inserted intraperitoneal by inner sleeve, and external adjustment adds with laparoscopic forceps auxiliary, accurately drainage tube is inserted " Wen hole " and promptly enters the omentum minus capsule, keep entering about 10-15cm, fully loosen no tension force and get final product.
In abdominal paracentesis tube placing operation implementation process, as need not to put into the omentum minus capsule, then do not need light transmitting filament, insert in the abdominal cavity by sleeve pipe and directly intraperitoneal drainage is put pipe.
Trocar sheath is made up of two semicanal bodies, and two semicanal body easily openables make it to take out from the abdominal cavity easily, and do not influence fixed drainage tube, that is: catch the hand-held handle of tearing of trocar sheath to tear to both sides, trocar sheath promptly is separated into two halves to be deviate from from the abdominal cavity, thereby drainage tube is stayed in the abdominal cavity.
See also Fig. 8 A and Fig. 8 B, if the trocar sheath tube wall is not provided with the optical fiber containing hole, also optical fiber 9 can be placed in the conduit 10, conduit is put into trocar sheath, because catheter length can reach 4-80cm, is longer than trocar sheath length, and it can be as required deeply to the position of seeking and visiting; Operation for convenience, trocar sheath is provided with handle 11.
