Description

Stomach wall hook pincers

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of apparatus of used for medical procedures.

Background technology

Along with constantly popularizing of laparoscopic surgery, the report of related complications also increases gradually.It is relevant to use towel forceps to carry skin pneumoperitoneum pin puncture manufacture of intraocular pneumoperitoneum in the clinical discovery, the generation of these complication and operation.Find that after deliberation when using traditional towel forceps to carry skin pneumoperitoneum pin puncture manufacture of intraocular pneumoperitoneum, except that operation inconvenience, following deficiency is still arranged: the method that (1) carries skin with towel forceps can only be mentioned skin, and can not effectively mention the holostrome stomach wall.So actual can not the puncture local abdominal cavity form effective space.When (2) carrying the skin puncture stomach wall with towel forceps, under the effect of a pair of rightabout power, the thickness of open textures such as subcutaneous superficial fascia can be elongated, and the thickness of original like this stomach wall will increase greatly, has increased difficulty to puncture, and particularly adiposis patient is more obvious.(3) pneumoperitoneum pin when puncture be owing to can not mention white line effectively and peritoneum down, in the time of outside puncture needle reaches peritoneum, peritoneum can only be pushed and be difficult for puncturing peritoneum to the deep.Like this, repeated localised puncture certainly will make the chance of interior blood vessel of abdomen or gastrointestinal damage increase, and the unsuccessful operating time that also prolonged of repeated localised puncture.

The utility model content

The purpose of this utility model is, provides a kind of simple to operate, the various damages that cause in the time of reducing the puncture of pneumoperitoneum pin, the stomach wall hook pincers that the various complication that the prevention puncture brings take place.

The technical scheme that its technical problem that solves this utility model adopts is:

A kind of stomach wall hook pincers comprise finger ring, preceding pincers handle, forceps major handle, the end of described forceps major handle be provided with and finger ring between angle be the drag hook of 80-85 degree.

The length of described drag hook is 7-8mm.

The utlity model has following beneficial effect:

(1) drag hook is directly mentioned the white line tissue, and its power upwards acts on superficial fascia, and fat deposit is compressed, and can make the thickness of abdominal wall attenuation, and puncture is easy to success, has also overcome the difficulty that some adiposis patients bring to puncture simultaneously.

(2) though the auxiliary pneumoperitoneum pin puncture of drag hook also belongs to the abdominal cavity of blindly puncturing, but after vertical drag hook is mentioned white line, make the stomach wall holostrome pull-up upward of site of puncture, caused the space of a limitation effectively in the abdominal cavity, site of puncture, needle point is away from organ in the abdomen, thereby provide a safety zone for puncture needle enters the abdominal cavity, can prevent effectively in the piercing process intraperitoneal blood vessel or gastrointestinal damage.

(3) in whole piercing process, peritoneum is hauled by a power that makes progress all the time, so puncture needle is easy to sting peritoneum, and penetrates the space of peritoneum, and the sense that falls through is fairly obvious.One-time successful puncture rate is high, the drawback of having avoided repeated localised puncture to bring, and can effectively prevent the generation of the various severe complications that bring of puncture.

(4) drag hook is made easily, and cost is low.

The specific embodiment

Below in conjunction with drawings and Examples this utility model is described in detail.

The sketch map of this utility model stomach wall hook pincers comprises finger ring 4, preceding pincers handle 3, forceps major handle 2 as shown in Figure 1, the end of forceps major handle 2 is curved have and finger ring between angle be the drag hook 1 of 80-85 degree, the length of drag hook is preferably 7-8mm.

The use sketch map of this utility model stomach wall hook pincers as shown in Figure 2, select under the stomach wall median line umbilicus 1-1.5 centimetre to sentence sharp knife during operation and cut 1.0 centimeters osculums, point of a knife vertically downward then, slowly thrust subcutaneous layer of fat, penetrate the tough and tensile tissue that point of a knife contacts behind the fat deposit and be hunter's line 6, this moment, sharp knife was no longer vertically exerted oneself standardized gently osculum (needn't sting white line) on white line.Respectively from skin thorn mouth locate vertical insertion drag hook with the assistant the other side by the patient, bill outwards hooks white line tissue and square vertically upward mentioning.Pneumoperitoneum pin 5 two pincers between thrust abdominal cavity 7 through the white line otch, having fall through the sense after connect the water filling empty needle, water column descend continuously the expression puncture needle gone into the abdominal cavity.Connect pneumoperitoneum apparatus manufacture of intraocular pneumoperitoneum.

Although the disclosed a kind of stomach wall hook pincers that relate to have been carried out special description with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
